Description

Uplink power adjustment method and related equipment

Technical Field

The embodiment of the application relates to the field of wireless communication, in particular to a technology for adjusting uplink power.

Background

In a wireless communication system, various data are transmitted between a terminal side device and an access network side device on an uplink and a downlink according to various protocol layers established by the 3rd generation partnership project (3 GPP) organization, and the data are control signaling or service data. These Protocol layers mainly include a Physical (PHY) layer, a Media Access Control (MAC) layer, a Radio Link Control (RLC), a Packet Data Convergence Protocol (PDCP) layer, and a Radio Resource Control (RRC) layer.

On a physical layer, the access network side device may send Downlink Control Information (DCI) on a Physical Downlink Control Channel (PDCCH), where the downlink control information includes a Transmit Power Control (TPC) command, and the TPC command indicates an uplink power adjustment amount for sending uplink data. The DCI may be specific to the terminal-side device (specific to), or may be specific to a certain terminal group including the terminal-side device. And under the condition that the uplink power adjustment mode is an accumulation mode, the current uplink power for sending the uplink data is the uplink power adjustment quantity indicated by the TPC command superimposed on the last uplink power, and the candidate adjustment quantity of the uplink power adjustment quantity is { -1,0,1,3} decibel (dB).

On the uplink, the terminal-side device may send low-priority traffic (e.g., enhanced mobile bandwidth (eMBB) traffic) and high-priority traffic (e.g., Ultra Reliable and Low Latency Communications (URLLC)) to the terminal. The access network side equipment indicates that the uplink power adjustment amount is a large value (for example, 3dB) when transmitting the high-priority service through the TPC command, so as to quickly increase the uplink power, thereby resisting interference of low-priority services transmitted by other terminal side equipment on the same time-frequency resource. When the terminal side device stops sending a certain priority service (e.g., a high priority service) and starts sending another priority service (e.g., a low priority service), the uplink power may have been accumulated to a large value, and the access network side device may need to reduce the uplink power but may use an adjustment amount of-1 dB to reduce the uplink power at the fastest speed, which may cause a large interference to the services (especially, the high priority service) sent by other terminal side devices.

Disclosure of Invention

In view of the foregoing problems, embodiments of the present application provide an uplink power adjustment method and related devices.

A first aspect of the embodiments of the present application provides an uplink power adjustment method, which includes the following steps.

The terminal side equipment receives downlink control information sent by access network side equipment, wherein the downlink control information indicates an uplink power adjustment amount when uplink data is sent; the terminal side equipment adjusts the uplink power according to the uplink power adjustment quantity; wherein,

when the priority of the uplink data is a first priority, indicating the uplink power adjustment amount from at least one candidate adjustment amount corresponding to the first priority by the downlink control information; when the priority of the uplink data is a second priority, indicating the uplink power adjustment amount from at least one candidate adjustment amount corresponding to the second priority by the downlink control information; the absolute value of the minimum negative value in the at least one candidate adjustment amount corresponding to the first priority is greater than or equal to the maximum positive value in the at least one candidate adjustment amount corresponding to the second priority.

In this case, the different priorities correspond to a set of candidate adjustment amounts respectively, and the access network side device and the terminal side device correspond the set of candidate adjustment amounts corresponding to the priority of the current uplink data to the candidate bit state of the downlink control information. The access network side device may indicate to the terminal side device which adjustment amount in the set of candidate adjustment amounts is an actual uplink power adjustment amount through an actual bit state in the downlink control information. Further, for two different priorities, taking the first priority and the second priority as an example, the absolute value of the minimum negative value in the set of candidate adjustment amounts corresponding to the first priority is greater than or equal to the maximum positive value in the set of candidate adjustment amounts corresponding to the second priority, even if the terminal side device switches from sending the uplink data of the second priority to sending the uplink data of the first priority, because the absolute value of the negative value of the candidate adjustment amount corresponding to the first priority is larger, the uplink power can be reduced more quickly, thereby reducing the interference to other terminal side devices.

Based on the first aspect, in a first possible implementation manner of the first aspect, an absolute value of a smallest negative value in at least one candidate adjustment amount corresponding to the first priority is greater than or equal to an absolute value of a smallest negative value in at least one candidate adjustment amount corresponding to the second priority. By applying the technical solution provided by the possible implementation manner, the maximum reduction degree in the candidate adjustment amounts corresponding to the first priority is higher than the maximum reduction degree in the candidate adjustment amounts corresponding to the second priority, which is beneficial for the terminal side device to reduce the uplink power more quickly when the terminal side device switches from sending the uplink data of the second priority to sending the uplink data of the first priority.

Based on the first aspect or the first possible implementation manner of the first aspect, in a second possible implementation manner of the first aspect, a maximum positive value of the at least one candidate adjustment amount corresponding to the first priority is smaller than or equal to a maximum positive value of the at least one candidate adjustment amount corresponding to the second priority. By applying the technical solution provided by the possible implementation manner, the maximum improvement degree of the candidate adjustment amount corresponding to the second priority is not higher than the maximum improvement degree of the candidate adjustment amount corresponding to the first priority, and the adjustment accuracy of the candidate adjustment amount corresponding to the first priority can be improved. For example, the maximum degree of improvement of the candidate adjustment amount corresponding to the first priority is +3dB, the maximum degree of improvement of the candidate adjustment amount corresponding to the second priority is +5dB, and in the case where the number of candidate bit states of the downlink control information is fixed (for example, 2 bits have 4 candidate bit states), the candidate adjustment amount corresponding to the first priority is 4 of 0 to 3dB, and the candidate adjustment amount corresponding to the second priority is 4 of 0 to 5 dB. Therefore, the accuracy of the adjustment amount candidate corresponding to the first priority is higher.

In a third possible implementation manner of the first aspect, based on any one of the first to the second possible implementation manners of the first aspect, the method further includes: the terminal side equipment determines the priority of the uplink data according to the downlink control information; the downlink control information indicates the priority of the uplink data, the transmission format used by the downlink control information indicates the priority of the uplink data, or the scrambling identifier used by the downlink control information indicates the priority of the uplink data. The possible implementation mode provides various design modes of the priority of the uplink data through the design of the downlink control information, so that the terminal side equipment can identify the priority of the uplink data according to the uplink control information.

wherein, when the priority of the second uplink data is higher than the priority of the first uplink data, the maximum positive value of at least one candidate adjustment amount of the second uplink power adjustment amount is greater than or equal to the maximum positive value of at least one candidate adjustment amount of the first uplink power adjustment amount; or, when the priority of the second uplink data is less than the priority of the first uplink data, an absolute value of a minimum negative value in at least one candidate adjustment amount of the second uplink power adjustment amount is greater than or equal to a maximum positive value in at least one candidate adjustment amount of the first uplink power adjustment amount.

Based on the second aspect, in a first possible implementation manner of the second aspect, the method further includes:

and the terminal side equipment receives a Radio Resource Control (RRC) message sent by the access network side equipment, wherein the RRC message indicates at least one candidate adjustment amount of the second uplink power adjustment amount and at least one candidate adjustment amount of the first uplink power adjustment amount under the condition that the priority of the second uplink data is higher than the priority of the first uplink data or under the condition that the priority of the second uplink data is lower than the priority of the first uplink data.

By applying the technical scheme provided by the third aspect, after the uplink power when the first uplink data is transmitted is rapidly increased, the rapid decrease of the uplink power when the terminal side device switches from transmitting the first uplink data to transmitting the second uplink data can be realized. Optionally, when the first uplink power adjustment amount is not greater than the preset threshold (that is, the uplink power when the first uplink data is sent is not rapidly increased), an absolute value of a minimum negative value in the candidate adjustment amounts of the second uplink power adjustment amount is not greater than a maximum positive value in the candidate adjustment amounts of the first uplink power adjustment amount or the preset threshold.

Detailed Description

In the architecture diagram of the wireless communication system shown in fig. 1, the wireless communication system includes a terminal-side device and an access network-side device, and optionally further includes a core network-side device. The wireless communication system may be a Long Term Evolution (LTE) system, and may also be a fifth generation mobile communication system (also called a New Radio (NR) communication system).

The terminal side device may be a terminal sold independently or a chip system in the terminal. The terminal is also called User Equipment (UE) or a mobile station (mobile station), and includes a mobile phone, a handheld internet of things device, wearable devices (wearable devices), a vehicle-mounted terminal, and the like.

The access network side device may be an independent wireless access device or a chip system in the wireless access device. The wireless access device may be a base station of various communication systems. Base stations can be classified into two major categories, macro base station (macro base station) and small base station (micro base station), and the small base station can be classified into micro base station (pico base station), pico base station (pico base station), and the like. The wlan access point may be a router, switch, etc.

And the terminal side equipment and the access network side equipment transmit data by establishing at least one Radio Bearer (RB). Wherein the data may comprise signaling data or traffic data. The radio bearer mainly used for transmitting the signaling data is a Signaling Radio Bearer (SRB), and the radio bearer mainly used for transmitting the service data is a Data Radio Bearer (DRB). The service data includes enhanced mobile broadband (eMBB) data, massive machine type communication (mtc) data, and Ultra Reliable and Low Latency Communication (URLLC) data. Different types of service data may correspond to different priorities, and different types of service data may also correspond to different priorities. The priority here is used to indicate the urgency of the data transmission. The higher the priority, the more urgent is the data transmission. For example, eMBB data is typically lower priority than URLLC data; different URLLC data may also correspond to different priorities.

In the conventional technology, a terminal side device transmits uplink data of a certain priority (e.g., URLLC data of high priority) by increasing uplink power, so as to avoid interference (e.g., interference generated on the same time-frequency resource) generated by other terminal side devices due to transmitting uplink data of other priorities (e.g., eMBB data of low priority). When the terminal-side device switches from transmitting uplink data of such priority to transmitting uplink data of other priority, it may be necessary to reduce uplink power to reduce interference to other terminal-side devices. However, due to the restriction of the existing standard protocol, the uplink power of the terminal-side device cannot be quickly reduced, so that the interference to the other terminal-side devices cannot be quickly reduced.

In view of the research on the above technical problem, various embodiments of the present application provide an uplink power adjustment method and related apparatus when transmitting uplink data, which are described in detail below.

The uplink data may be service data such as the aforementioned URLLC data, eMBB data, mtc data, and the like; the uplink data may also be various uplink control signaling, such as Radio Resource Control (RRC) signaling, Hybrid Automatic Repeat reQuest-acknowledgement/non-acknowledgement (HARQ-ACK/NACK) information, and the like; the uplink data can also be randomly accessed to a preamble (preamble); the uplink data may also be an uplink reference signal, such as a Sounding Reference Signal (SRS), a demodulation reference signal (DMRS). The aforementioned service data is mainly carried on a Physical Uplink Shared Channel (PUSCH) in the physical layer, and is also designed to be carried on a Physical Uplink Control Channel (PUCCH) in the physical layer in some documents; the aforementioned uplink control signaling may be carried mainly on PUCCH, but in some documents is also designed to be carried in PUSCH (for example, HARQ-ACK/NACK may be carried on PUSCH to implement capability test on access network side equipment); the aforementioned random access preamble may be carried on a Physical Random Access Channel (PRACH) in the physical layer.

Optionally, in the technical solutions provided in the embodiments of the present application, the uplink power adjustment mode is an accumulation mode. The accumulation mode is that when the terminal side device sends uplink data, the uplink power of this time is the uplink power adjustment amount indicated by the uplink power of the last time superimposed on the received downlink control information (for example, the TPC command). The access network side device may measure the uplink power of the terminal side device, and use a difference between the measured uplink power and a preset uplink power as a reference for determining the uplink power adjustment amount. For example, if the measured uplink power is lower than the preset uplink power, the uplink power adjustment amount indicated by the TPC command is a positive value, so as to increase the current uplink power; and if the measured uplink power is higher than the preset uplink power, the uplink power adjustment quantity indicated by the TPC command is a negative value so as to reduce the current uplink power.

A first embodiment of the present application provides an uplink power adjustment method, as shown in fig. 2, which includes the following steps.

A terminal side device receives downlink control information sent by an access network side device, where the downlink control information indicates an uplink power adjustment amount when uplink data is sent.

In 201, the access network side may carry the downlink control information through a Physical Downlink Control Channel (PDCCH) in a physical layer. Optionally, the downlink control information includes a Transmit Power Control (TPC) field, where the TPC field indicates an uplink power adjustment amount when uplink data is transmitted. The candidate time-frequency resource position of the PDCCH is preset between the access network side device and the terminal side device, and the access network side device may also notify the terminal side device through an RRC message, so that the terminal side device blindly detects the PDCCH at the candidate time-frequency resource position of the PDCCH. The process of sending the RRC message by the access network side device may be a random access process, a process of switching the terminal side device out of or to the access network side device, or a process of reestablishing a connection between the terminal side device and the access network side device due to a radio link failure, and the like.

In 201, the terminal side device may use an identifier specific to the terminal side device, an identifier specific to a terminal group to which the terminal side device belongs, or an identifier specific to a cell in which the terminal side device is located, to blindly detect the PDCCH, thereby acquiring the downlink control information. Optionally, the identifier is a Radio Network Temporary Identifier (RNTI). In the NR system, DCI format 0_0 and DCI format 0_1 are DCI scrambled using RNTI specific to the terminal side device, which can receive both DCI using RNTI specific to the terminal side device. In the NR system, DCI format 2_2 is DCI scrambled using RNTI specific to the terminal group, and the side device can receive such DCI using RNTI specific to the terminal group.

As a possible implementation manner, for example, as shown in table 1, when the priority of the uplink data is a first priority, the downlink control information indicates the uplink power adjustment amount from at least one candidate adjustment amount corresponding to the first priority; and when the priority of the uplink data is a second priority, indicating the uplink power adjustment amount from at least one candidate adjustment amount corresponding to the second priority by the downlink control information. In this implementation, the at least one candidate adjustment amount corresponding to the first priority may be partially different from the at least one candidate adjustment amount corresponding to the second priority, or may be all different.

Optionally, an absolute value of a smallest negative value of the at least one candidate adjustment amount corresponding to the first priority is greater than or equal to a largest positive value of the at least one candidate adjustment amount corresponding to the second priority. In this optional implementation manner, the maximum reduction degree of the uplink power adjustment amount corresponding to the first priority is higher than the maximum improvement degree of the uplink power adjustment amount corresponding to the second priority, and even if the terminal side switches from the uplink data of the second priority to the uplink data of the first priority, since the uplink power is reduced faster when the uplink data of the first priority is transmitted, interference (especially interference on the same time-frequency resource) to other terminal side devices can be reduced.

Optionally, the first priority is lower than the second priority. For example, if the first priority is the priority of the eMBB data, the uplink data is the eMBB data; and if the second priority is the priority of the URLLC data, the uplink data is the URLLC data. The access network side device generally arranges high priority data to be transmitted as early as possible or at a high quality resource position. The priority level may be indicated by the traffic type. For example, for traffic types eMBB data and URLLC data, the priority of eMBB data is lower than the priority of URLLC data. The priority level may also be indicated by the quality of service (QoS) requirement. For example, data with higher QoS requirements may have higher priority and data with lower QoS requirements may have lower priority. For example, if the QoS requirement of the first URLLC data is high and the QoS requirement of the second URLLC data is low, the priority of the first URLLC data is higher than the priority of the second URLLC data.

TABLE 1

Optionally, an absolute value of a smallest negative value of the at least one candidate adjustment amount corresponding to the first priority is greater than or equal to an absolute value of a smallest negative value of the at least one candidate adjustment amount corresponding to the second priority.

Optionally, a maximum positive value of the at least one candidate adjustment amount corresponding to the first priority is smaller than or equal to a maximum positive value of the at least one candidate adjustment amount corresponding to the second priority.

As an implementation, the method further comprises: the terminal side equipment determines the priority of the uplink data according to the downlink control information; the downlink control information indicates the priority of the uplink data, the transmission format used by the downlink control information indicates the priority of the uplink data, or the scrambling identifier used by the downlink control information indicates the priority of the uplink data.

The priority of the uplink data is indicated by a field composed of at least one bit in the downlink control information, and the terminal side device can make sure the priority of the uplink data by reading the field. For example, when the field indicates 00, the uplink data is of a first priority; when the field indicates 01, the uplink data is of a second priority; when the field indicates 10, the uplink data is the third priority; and when the field indicates 11, the uplink data is of a fourth priority. Optionally, the field may be a data type field, and when the field indicates a data type of uplink data, the terminal side device may determine the priority of the uplink data according to the data type. Optionally, the field may further define a mapping type (mapping type) field in the NR system, and when the field indicates mapping type B, the priority of the uplink data is the priority of the URLLC data, and when the field indicates mapping type a, the priority of the uplink data is lower than the priority of the URLLC data.

The transmission format of the downlink control information indicates the priority of the uplink data. For example, when the downlink control information is a transmission format corresponding to URLLC data, the terminal-side device may determine that the uplink data is high-priority data; when the downlink control information is in a transmission format corresponding to eMMC data, the terminal side device may determine that the uplink data is lower priority data than URLLC data.

The scrambling flag of the downlink control information is used to perform Cyclic Redundancy Check (CRC) on the downlink control information. The scrambling identity may be an identity specific to the terminal side device, such as the aforementioned RNTI specific to the terminal side device; the scrambling identifier may also be an identifier specific to a terminal group to which the terminal-side device belongs, or an identifier of a serving cell in which the terminal-side device is located.

And 202, the terminal side equipment adjusts the uplink power according to the uplink power adjustment amount.

In 202, as a possible implementation manner, taking the uplink data carried on the PUSCH as an example, under the condition of the serving cell c, the activated uplink BWP b of the carrier f and the PUSCH transmission opportunity i, the terminal side device may adjust the uplink power of the PUSCH according to the following formula:

wherein, P_CMAX,f,c(i) The allowed maximum transmission power for the PUSCH transmission opportunity i for carrier f on serving cell c. P_{O_PUSCH,b,f,c}(j) In order to expect the power received on a single Resource Block (RB), the value is related to the parameter j, and is configured by the access network side device through an RRC message. In the NR system, j-0 corresponds to a PUSCH used for random access, j-1 corresponds to an unlicensed PUSCH, and j>Corresponding to 2 is PUSCH scheduled by downlink control information. PL_b,f,c(q_d) For downlink path loss estimation, where q_dReference signal index used for downlink path loss estimation. Alpha is alpha_b,f,c(j) Is a path loss compensation factor. P_{O_PUSCH,b,f,c}(j) And alpha_b,f,c(j) All configured by RRC message, and are open-loop power control parameters. Delta_TF,b,f,c(i) For the purpose of transmitting power offset, the method is suitable for a single input multiple output (MIMO) layer transmission scene and is used for describing expected received power offset caused by different adjustment modes and code rate changes.

Is the serving cell c, carrier f, the resource size (e.g., number of RBs) that activates the PUSCH transmission opportunity i allocation in the uplink BWP bMesh), μ is subcarrier spacing configuration.

Indicating that the transmit receive power is directly proportional to the allocated transmission bandwidth. f. of_b,f,cAnd (i, l) represents an uplink power adjustment amount indicated by the downlink control information (e.g., TPC command). Wherein, the parameter l is the index of the closed loop power control process, and in the NR system, at most two closed loop power control processes can be configured in one service cell.

By applying the technical scheme provided by the first embodiment of the present application, different priorities respectively correspond to a set of candidate adjustment amounts, and the access network side device and the terminal side device can correspond the set of candidate adjustment amounts corresponding to the priority of the current uplink data to the candidate bit state of the downlink control information. The access network side device may indicate to the terminal side device which adjustment amount in the set of candidate adjustment amounts is an actual uplink power adjustment amount through an actual bit state in the downlink control information. Further, for two different priorities, taking the first priority and the second priority as an example, the absolute value of the minimum negative value in the set of candidate adjustment amounts corresponding to the first priority is greater than or equal to the maximum positive value in the set of candidate adjustment amounts corresponding to the second priority, even if the terminal side device switches from sending the uplink data of the second priority to sending the uplink data of the first priority, because the absolute value of the negative value of the candidate adjustment amount corresponding to the first priority is larger, the uplink power can be reduced more quickly, thereby reducing the interference to other terminal side devices.

A second embodiment of the present application provides an uplink power adjustment method, as shown in fig. 3, which includes the following steps.

301, a terminal side device receives first downlink control information sent by an access network side device, where the first downlink control information indicates a first uplink power adjustment amount when first uplink data is sent.

The manner in which the terminal side device receives the first downlink control information in 301 is similar to the manner in which the terminal side device receives the downlink control information in 201, and reference may be made to 201 specifically.

And 302, the terminal side equipment adjusts the uplink power according to the first uplink power adjustment amount.

The terminal side device in 302 adjusts the first uplink power in a similar manner as the terminal side device in 202 adjusts the uplink power, which can refer to 202.

303, the terminal side device receives second downlink control information sent by the access network side device, where the second downlink control information indicates a second uplink power adjustment amount when sending second uplink data.

The manner in which the terminal side device receives the second downlink control information in 303 is similar to the manner in which the terminal side device receives the downlink control information in 201, and reference may be made to 201 specifically.

304, the terminal side device adjusts the uplink power again according to the second uplink power adjustment amount and the adjusted uplink power.

The terminal side device in 304 adjusts the uplink power again in a similar manner as the terminal side device in 202 adjusts the uplink power, and 202 is referred to.

As a possible implementation manner, in a case that the priority of the second uplink data is higher than the priority of the first uplink data, a maximum positive value (for example, candidate adjustment amount 1 in table 2) of at least one candidate adjustment amount of the second uplink power adjustment amount is greater than or equal to a maximum positive value (for example, candidate adjustment amount 2 in table 2) of at least one candidate adjustment amount of the first uplink power adjustment amount. In this implementation, as shown in 440 of fig. 4, the first uplink data is low priority data, the second uplink data is high priority data, and the terminal side device switches from transmitting the low priority data to transmitting the high priority data. Compared with the degree of maximum promotion of the uplink power when the low-priority data is sent, the uplink power when the high-priority data is sent can be promoted more quickly, and the high-priority data is prevented from being interfered as far as possible, particularly the interference of the low-priority data on the same time-frequency resource by other terminal side equipment.

TABLE 2

As another possible implementation manner, in a case that the priority of the second uplink data is lower than the priority of the first uplink data, an absolute value of a smallest negative value in at least one candidate adjustment amount of the second uplink power adjustment amount is greater than or equal to a largest positive value in at least one candidate adjustment amount of the first uplink power adjustment amount (for example, candidate adjustment amounts 3 and 4 in table 2). In this implementation, as shown in 420 in the uplink data transmission skip diagram shown in fig. 4, in this implementation, the first uplink data is high-priority data, the second uplink data is low-priority data, and the terminal-side device switches from sending the high-priority data to sending the low-priority data. Compared with the degree of maximally improving the uplink power when sending high-priority data, the uplink power when sending low-priority data can be reduced more quickly, so that the interference generated by the low-priority data is avoided as much as possible, and particularly the interference to the high-priority data of other terminal side equipment in the same time-frequency resource is avoided.

Optionally, in a case that the priority of the second uplink data is smaller than the priority of the first uplink data, an absolute value of a smallest negative value of the at least one candidate adjustment amount of the second uplink power adjustment amount is greater than or equal to an absolute value of a smallest negative value of the at least one candidate adjustment amount of the first uplink power adjustment amount (e.g., candidate adjustment amount 2 in table 2). In this implementation, the terminal-side device switches from sending high priority data to sending low priority data. Compared with the precision with which the uplink power can be adjusted when high-priority data is transmitted, the precision with which the uplink power can be adjusted when low-priority data is transmitted is higher.

As another possible implementation manner, as shown in 410 and 430 in fig. 4, in the case that the priority of the second uplink data is equal to the priority of the first uplink data, both the first uplink power adjustment amount indicated by the first downlink control information and the second uplink power adjustment amount indicated by the second downlink control information are non-negative values or non-positive values. In this implementation, the priority of the uplink data sent by the terminal-side device is not changed, and therefore, if the uplink power is raised when the terminal-side device sends the first uplink data, the uplink power is still raised when the terminal-side device sends the second uplink data; if the uplink power is reduced when the terminal side equipment transmits the first uplink data, the uplink power is still reduced when the terminal side equipment transmits the second uplink data. Therefore, the terminal side equipment is prevented from being inconsistent with the adjustment direction of the uplink power when the second uplink data is transmitted after the information of the adjustment direction (lifted or lowered) of the uplink power when the first uplink data is transmitted is lost.

As a possible implementation manner, the terminal side device receives a radio resource control RRC message sent by the access network side device, where the RRC message indicates at least one candidate adjustment amount of the second uplink power adjustment amount and at least one candidate adjustment amount of the first uplink power adjustment amount when the priority of the second uplink data is higher than the priority of the first uplink data or when the priority of the second uplink data is lower than the priority of the first uplink data. By applying the possible implementation manner, since the RRC message supports message segmentation, the terminal side device can easily implement the above technical scheme compared with other protocol layer messages, so as to obtain the required candidate adjustment amount.

Optionally, the method further comprises: the terminal side equipment determines the priority of the first uplink data according to the first downlink control information; and the terminal side equipment determines the priority of the second uplink data according to the second downlink control information. Wherein, the priority of the first uplink data is indicated in the first downlink control information, the transmission format used by the first downlink control information indicates the priority of the first uplink data, or the scrambling identifier used by the first downlink control information indicates the priority of the first uplink data; the second downlink control information indicates the priority of the second uplink data, the transmission format used by the second downlink control information indicates the priority of the second uplink data, or the scrambling identifier used by the second downlink control information indicates the priority of the second uplink data. This alternative implementation is similar to the manner of identifying the priority of the uplink data in the first embodiment, and may specifically refer to the description related to the first embodiment.

By applying the technical scheme provided by the second embodiment of the present application, based on the skip state of the priorities of the two uplink data, after the uplink power when the first uplink data is sent is rapidly increased, the terminal side device can rapidly decrease the uplink power when the terminal side device switches from sending the first uplink data to sending the second uplink data.

A third embodiment of the present application provides an uplink power adjustment method, as shown in fig. 5, which includes the following steps.

501, a terminal side device receives first downlink control information sent by an access network side device, where the first downlink control information indicates a first uplink power adjustment amount when first uplink data is sent.

The manner in which the terminal side device receives the first downlink control information in 501 is similar to the manner in which the terminal side device receives the downlink control information in 201, and reference may be made to 201 specifically.

502, the terminal side device adjusts the uplink power according to the first uplink power adjustment amount.

The terminal side device in 502 adjusts the first uplink power in a similar manner as the terminal side device in 202 adjusts the uplink power, which can refer to 202.

503, the terminal side device receives second downlink control information sent by the access network side device, where the second downlink control information indicates a second uplink power adjustment amount when sending second uplink data.

503, the terminal side device receives the second downlink control information in a similar manner to the terminal side device receives the downlink control information in 201, and reference may be made to 201 specifically.

And 504, the terminal side device adjusts the uplink power again according to the second uplink power adjustment amount and the adjusted uplink power.

The terminal side device in 504 adjusts the uplink power again in a similar way as the terminal side device in 202 adjusts the uplink power, and 202 is referred to.

As a possible implementation manner, if the priority of the first uplink data (e.g. URLLC data) is high, then at least one candidate adjustment amount of the first uplink power adjustment amount is a candidate adjustment amount specific to the first uplink data (e.g. a candidate adjustment amount corresponding to URLLC data in table 3).

As a possible implementation manner, as shown in table 3, in a case that the priority of the first uplink data (e.g., URLLC data in table 3) is higher than the priority of the second uplink data (e.g., eMBB data in table 3), and the first uplink power adjustment amount is greater than or equal to a preset threshold, an absolute value of a smallest negative value in at least one candidate adjustment amount of the second uplink power adjustment amount (e.g., candidate adjustment amount 1 corresponding to eMBB data in table 3) is not less than an absolute value of a largest positive value or a smallest negative value in at least one candidate adjustment amount of the first uplink power adjustment amount or the preset threshold. In other cases, at least one candidate adjustment amount of the second uplink power adjustment amount follows a candidate adjustment amount defined by conventional techniques (e.g., in release 15 of the 3GPP NR standard), such as candidate adjustment amount 2 corresponding to the eMBB data in table 3. Alternatively, the preset threshold may be a maximum positive value (e.g. 3dB) of the candidate adjustment amounts defined by the conventional technique, or may be a maximum positive value (e.g. 5dB corresponding to the URLLC data in table 3) of the candidate adjustment amounts specific to the first uplink data. Optionally, the preset threshold may be configured to the terminal side device by an access network side device through an RRC message, or may be preset in the terminal side device when the terminal side device is manufactured.

TABLE 3

As another possible implementation, the method further includes: the terminal side equipment determines the priority of the first uplink data according to the first downlink control information; and the terminal side equipment determines the priority of the second uplink data according to the second downlink control information. Optionally, the priority of the first uplink data is indicated in the first downlink control information, the transmission format used by the first downlink control information indicates the priority of the first uplink data, or the scrambling identifier used by the first downlink control information indicates the priority of the first uplink data; the second downlink control information indicates the priority of the second uplink data, the transmission format used by the second downlink control information indicates the priority of the second uplink data, or the scrambling identifier used by the second downlink control information indicates the priority of the second uplink data. This implementation is similar to the manner of identifying the priority of the uplink data in the first embodiment, and specific reference may be made to the description related to the first embodiment.

In the technical solution provided in the third embodiment of the present application, at least one candidate adjustment amount of the uplink power adjustment amount of the high-priority uplink data is a candidate adjustment amount specific to the high-priority uplink data (for example, a candidate adjustment amount corresponding to URLLC data in table 3). When the terminal side equipment transmits the uplink data with low priority, the candidate adjustment amount of the uplink power is related to the adjustment amount of the uplink power with high priority. If the terminal side equipment changes from high-priority uplink data to sending low-priority uplink data and the uplink power adjustment amount is not less than the preset threshold when the high-priority uplink data is sent, the absolute value of the minimum negative value in at least one candidate adjustment amount of the uplink power adjustment amount when the low-priority uplink data is sent is not less than the absolute value of the maximum positive value or the minimum negative value in at least one candidate adjustment amount corresponding to the high-priority uplink data or the preset threshold (for example, candidate adjustment amount 1 corresponding to eMBB data in table 3); otherwise, for other cases, the candidate adjustment amount defined by the conventional technique (e.g., candidate adjustment amount 1 corresponding to the eMBB data in table 3) is used.

By applying the technical scheme provided by the third embodiment of the present application, in combination with different situations, after the uplink power when the first uplink data is sent is quickly raised, the terminal side device can quickly lower the uplink power when the terminal side device switches from sending the first uplink data to sending the second uplink data, so as to reduce interference that may be generated when the second uplink data is sent, and particularly interference that is generated when other terminal side devices send the uplink data on the same time-frequency resource.
