Description

Transmission method, device, equipment and storage medium of uplink voice service
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, a device, and a storage medium for transmitting an uplink voice service.
Background
Currently, in The 3rd Generation Partnership Project (3 GPP) protocol, there are two typical cell types in The Long Term Evolution (LTE) system: frequency Division Duplex (FDD) cells and Time Division Duplex (TDD) cells. An FDD cell has a pair of carriers: an uplink carrier and a downlink carrier. The UE transmits a Physical Random Access Channel (PRACH), a Physical Uplink Shared Channel (PUSCH), a Physical Uplink Control Channel (PUCCH), a Sounding Reference Signal (SRS), and a PUSCH/PUCCH Demodulation Reference Signal (DMRS) to a base station through an Uplink carrier, and the base station broadcasts a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), and a Physical Broadcast Channel (PBCH) in a cell through the downlink carrier. Meanwhile, the base station sends Downlink Physical channels and Downlink Physical signals, such as a Physical Downlink Control Channel (PDCCH for short) and a Physical Downlink Shared Channel (PDSCH for short), to the UE through a Downlink carrier. A TDD cell has only one carrier that supports several uplink and downlink allocations, each of which divides 10 subframes in each 10ms radio frame on the carrier into uplink and downlink subframes. And the UE and the base station respectively transmit corresponding uplink physical channels/uplink physical signals and downlink physical channels/downlink physical signals through the uplink subframe and the downlink subframe. Specifically, the uplink physical channel, the uplink physical signal, the downlink physical channel, and the downlink physical signal transmitted in the TDD cell are the same as those of the FDD cell.
In actual networking, the following scenarios exist:
(1) There is a pair of FDD carriers, and there are one or more uplink carriers with different frequency points.
(2) There is one TDD carrier and one or several ascending carriers with different frequency points.
In practical service application, there are service demands for video uploading in many scenarios, and the demand for uplink bandwidth in an FDD cell or a TDD cell is far greater than the demand for downlink bandwidth. For the actual networking scenario and service application scenario, those skilled in the art need to solve the problem of how to transmit the uplink voice service of the UE in the networking scenario.

Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the disclosure, as detailed in the appended claims.
The terms "comprising" and "having," and any variations thereof, in the description and claims of this invention and the drawings described herein are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but may alternatively include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Firstly, the application scene related to the invention is introduced:
in actual networking, the following scenarios exist:
(1) There is a pair of FDD carriers, and there are one or more uplink carriers with different frequency points.
(2) There is one TDD carrier and one or several uplink carriers with different frequency points.
In practical service application, there are service demands for video uploading in many scenarios, and the demand for uplink bandwidth in an FDD cell or a TDD cell is far greater than the demand for downlink bandwidth.
In view of the actual networking scenario and the service application scenario, it is necessary to solve the problem how to use a pair of FDD carriers or a TDD carrier and at least one uplink carrier with different frequency points to meet the requirement that the uplink bandwidth is far greater than the downlink bandwidth in actual application.
In the embodiment of the present invention, a special FDD cell or a special TDD cell is established in the networking scenario. The special FDD cell includes 1 pair of FDD carriers and 1 or more different-frequency-point uplink carriers. And 1, the FDD carriers are respectively the only downlink carrier and the uplink main carrier in the special FDD cell, and other uplink carriers are uplink auxiliary carriers in the special FDD cell. These carriers all adopt FDD frame structures. The special TDD cell comprises 1 TDD carrier and 1 or more different frequency point uplink carriers. The only TDD carrier in the special TDD cell adopts a TDD frame structure and simultaneously supports uplink and downlink service transmission, the TDD carrier is an uplink main carrier and a downlink carrier, and other uplink carriers adopt FDD frame structures and are uplink auxiliary carriers.
In a particular FDD or TDD cell, there are multiple uplink carriers, and therefore it is necessary to determine how to transmit uplink voice traffic of the UE in the particular FDD or TDD cell.
The method of the embodiment of the invention transmits the uplink voice service of the UE through the uplink semi-persistent scheduling (SPS) PUSCH resource distributed on a plurality of uplink carriers selected in the special FDD/TDD cell, and activates or deactivates the uplink SPS PUSCH resource on one uplink carrier with the uplink SPS PUSCH resource through the PDCCH scrambled by the SPS C-RNTI on the downlink carrier in the special cell, thereby realizing the transmission of the uplink voice service of the UE in the special FDD cell or the TDD cell. Hereinafter, the uplink SPS PUSCH resource is simply referred to as: and (4) uplink SPS resources. For a special FDD cell and a special TDD cell, any downlink physical channel or any downlink physical signal sent by the base station to the UE is sent through a unique downlink carrier in the special cell, for example, a dedicated signaling sent by the base station to the UE, such as configuration information of an uplink SPS resource of each first carrier, configuration information of a first TPC command, and configuration information of a second TPC command, which are described below, is sent to the UE through the PDSCH. The scheduling information of the PDSCH is transmitted to the UE through the PDCCH. And both the PDSCH and the PDCCH are sent to the UE through a unique downlink carrier in the special cell.
Fig. 1 is a flowchart illustrating a method for transmitting an uplink voice service according to an embodiment of the present invention. The main execution body of the embodiment is a base station. As shown in fig. 1, the method provided by this embodiment includes:
step 101, a base station determines a plurality of first carriers according to capability information reported by User Equipment (UE), and allocates an uplink SPS resource to each of the plurality of first carriers; the capability information includes an indication that the UE supports a special cell and frequency band information of an uplink carrier supported by the UE.
Specifically, for a UE accessing a special FDD or TDD cell, the UE reports capability information to a base station.
If the UE carries the indication of supporting the special cell and the frequency band information of the supported uplink carrier in the capability information, the base station determines each uplink carrier supported by the UE in the current cell according to the frequency band information of the uplink carrier supported by the UE.
The indication of the special cell is used for indicating the UE to: only a special FDD cell, only a special TDD cell, or both a special FDD cell and a special TDD cell.
When the UE applies for the uplink voice service, the base station selects a plurality of first carriers from the determined uplink carriers supported by the UE, and the base station allocates uplink SPS resources to the UE on each of the first carriers for transmitting the voice service of the UE.
Step 102, the base station sends configuration information of the uplink SPS resource of each first carrier in the plurality of first carriers to the UE.
And after receiving the configuration information of the uplink SPS resources of each first carrier in the plurality of first carriers, the UE stores the configuration information and feeds back a response message to the base station.
Specifically, the base station notifies the UE of the configuration information of the uplink SPS resource of each of the determined multiple first carriers through dedicated signaling. Optionally, the dedicated signaling is a Radio Resource Control (RRC) reconfiguration message.
And the UE receives the special signaling sent by the base station, stores the configuration information of the uplink SPS resource of each first carrier in a plurality of first carriers in the special signaling, and feeds back a response message to the base station. Optionally, the response message is an RRC reconfiguration complete message.
103, the base station selects a second carrier from the plurality of first carriers, and sends first bearer information on a PDCCH scrambled by a Semi-Persistent Scheduling Cell Radio Network Temporary Identifier (SPS C-RNTI) to the UE, so that the UE activates an uplink SPS resource configured on the second carrier according to the first bearer information on the PDCCH, and sends a physical uplink shared channel, PUSCH, on the second carrier through the uplink SPS resource according to the configuration information of the SPS resource; and the PUSCH bears a transmission block of the voice service of the UE.
Before step 103, the method further comprises:
and the base station allocates SPS C-RNTI to the UE and sends the configuration information of the SPS C-RNTI to the UE.
And after receiving the configuration information of the SPS C-RNTI, the UE stores the configuration information and feeds back a response message to the base station.
Preferably, the base station may send the configuration information of the SPS C-RNTI to the UE in step 102.
Preferably, the configuration information of the SPS C-RNTI and the configuration information of the uplink SPS resources of each first carrier may be sent to the UE through the same dedicated signaling. And after receiving the configuration information of the uplink SPS resources and the SPS C-RNTI configuration information of each first carrier transmitted by the same special signaling, the UE stores the information and only feeds back a response message to the base station.
The SPS C-RNTI is used to scramble Cyclic Redundancy Check (CRC) information of a transmission block on the PDCCH, where the transmission block on the PDCCH is activation or deactivation information of an uplink SPS resource on a certain uplink carrier in this embodiment.
Further, before the voice service of the UE starts to be transmitted, the base station selects a second carrier from a plurality of first carriers configured with the uplink SPS resources, and sends the PDCCH scrambled by the SPS C-RNTI so as to transmit the first bearing information to the UE. The first bearer information includes: activation information of SPS resources on a second carrier. Optionally, the first bearer information includes: and the activation indication domain has a value of 1 and is used for indicating the uplink SPS resources on the second carrier indicated by the activation carrier indication domain. Specifically, the first carriers are numbered from 0, the numbers are from 0 to N-1, and N is the total number of the first carriers. And the value of the carrier indication domain in the first bearer information is the number of the second carrier.
And the UE monitors the PDCCH scrambled by the SPS C-RNTI after acquiring the configuration information of the uplink SPS resources and the configuration information of the SPS C-RNTI on each first carrier. And when the PDCCH scrambled by the SPS C-RNTI is detected, first bearing information on the PDCCH is acquired, and the UE activates the uplink SPS resource configured on the second carrier according to the first bearing information on the PDCCH.
After the activation of the uplink SPS resource on the second carrier, the UE periodically transmits, according to the configuration information of the SPS resource on the second carrier, a PUSCH on the second carrier through the uplink SPS resource, where the PUSCH carries a transport block of an uplink voice service of the UE.
And the base station receives a PUSCH (physical uplink shared channel) sent by the UE on the second carrier through the uplink SPS resource, and obtains a transmission block of the uplink voice service of the UE by decoding the transmission block on the PUSCH.
In the embodiment of the invention, the uplink voice service of the UE is transmitted through the uplink SPS resource on a certain uplink carrier in a special FDD cell or a special TDD cell. Specifically, a transport block is generated for the service every 20ms, and optionally, the base station configures uplink SPS resources with a period of 20ms for the UE on each first carrier to transmit the service. When the uplink voice service is started or restarted, the uplink SPS resource configured on a certain first carrier of the UE is activated through the bearing information on the PDCCH, when the uplink voice service is ended or the service enters a silent period, the currently activated uplink SPS resource is deactivated through the bearing information on the PDCCH, and the PDCCH does not need to be periodically sent during the activation of the uplink SPS resource. Compared with the method that the configuration information of the PUSCH resource dynamically scheduled is sent to the UE through the PDCCH in each 20ms period so as to transmit only one transmission block of the uplink voice service in the period, the transmission of the voice service through the uplink SPS resource can greatly save the PDCCH resource.
In the method of this embodiment, a base station determines a plurality of first carriers according to capability information reported by a UE, and allocates an uplink SPS resource to each of the plurality of first carriers; the capability information comprises an indication that the UE supports a special cell and frequency band information of an uplink carrier supported by the UE; the base station sends configuration information of the uplink SPS resource of each first carrier in the plurality of first carriers to the UE; the base station selects a second carrier from the plurality of first carriers, and sends a PDCCH scrambled by an SPSC-RNTI to the UE, wherein a transmission block on the PDCCH is first bearing information, so that the UE activates uplink SPS resources configured on the second carrier according to the first bearing information on the PDCCH and sends a PUSCH on the second carrier through corresponding uplink SPS resources according to the configuration information of the activated uplink SPS resources; the PUSCH bears the transmission block of the voice service of the UE, so that the uplink SPS resource of the corresponding uplink carrier wave is activated through the first bearing information on the PDCCH scrambled by the SPS C-RNTI, and the uplink voice service is transmitted through the activated uplink SPS resource.
On the basis of the above embodiment, optionally, the following operations may be further performed after step 103:
the base station acquires a BLock Error Rate (BLock Error Rate, BLER for short) of the transmission BLock on the PUSCH according to the decoding result of the transmission BLock on the PUSCH sent by the UE;
and if the BLER of the PUSCH meets a preset condition, the base station selects a third carrier from the plurality of first carriers, and sends second bearing information on the PDCCH scrambled by the SPS C-RNTI to the UE, so that the UE activates uplink SPS resources configured on the third carrier according to the second bearing information of the PDCCH, and sends the PUSCH on the third carrier through the uplink SPS resources according to the configuration information of the uplink SPS resources on the third carrier, and the PUSCH bears the transmission blocks of the voice service of the UE.
Specifically, the base station counts the decoding result of the transport block on the PUSCH transmitted by the currently activated uplink SPS resource, and obtains the BLER of the transport block of the voice service. And when the counted BLER meets the preset condition, the base station considers that the quality of the voice service on the uplink carrier wave is poor. The base station selects an uplink carrier (namely, a third carrier) with good radio channel quality from other first carriers configured with the uplink SPS resources, and then activates the uplink SPS resources on the third carrier through second bearing information on the PDCCH scrambled by the SPS C-RNTI.
Wherein, the preset condition may be: and when the counted number of the transmission blocks on the PUSCH exceeds a preset first threshold value and the counted BLER value of the transmission blocks on the PUSCH is greater than a preset second threshold value, the base station considers that the quality of the voice service on the uplink carrier wave is deteriorated. Of course, the base station may also adopt other preset conditions.
And after receiving the second bearing information scrambled by the SPS C-RNTI on the PDCCH, the UE activates the uplink SPS resource of the corresponding third carrier according to the second bearing information and continuously transmits the transmission block of the voice service through the uplink SPS resource on the third carrier. Optionally, the second bearer information includes: the value of the carrier indication domain is the number of the third carrier, and the value of the activation indication domain is 1, which is used for indicating the uplink SPS resources on the third carrier indicated by the activation carrier indication domain.
It is to be understood here that: after the UE has the activated uplink SPS resource, if the uplink SPS resource activation information on the PDCCH is received again, the UE activates a new uplink SPS resource according to the new uplink SPS resource activation information, and transmits a transport block of a voice service of the UE through the new uplink SPS resource, where the previously activated uplink SPS resource is temporarily unused.
Further, optionally, after the second bearer information on the PDCCH scrambled by the SPS C-RNTI is sent to the UE, the following operations may also be performed:
and after correctly decoding the transport block of the PUSCH received on the third carrier wave, the base station sends third bearing information on the PDCCH scrambled by the SPS C-RNTI to the UE, so that the UE releases the uplink SPS resource on the second carrier wave according to the third bearing information on the PDCCH.
Specifically, after the base station receives the PUSCH transmitted by the UE through the uplink SPS resource on the newly activated third carrier and correctly decodes the transport block on the PUSCH, the base station sends the third bearer information on the PDCCH scrambled by the SPS C-RNTI, which is used to deactivate the uplink SPS resource of the previously used second carrier. Optionally, the third bearer information includes: the carrier indication domain and the activation indication domain, the value of the carrier indication domain is the number of the second carrier, and the value of the activation indication domain is 0, which is used for indicating the deactivation of the uplink SPS resources on the second carrier indicated by the carrier indication domain.
And after the UE receives third bearing information on the PDCCH scrambled by the SPS C-RNTI, releasing the uplink SPS resources on the second carrier according to the third bearing information. Further, the UE may still store the configuration information of the uplink SPS resource on the second carrier, so as to activate the SPS resource on the second carrier again later according to the bearer information on the PDCCH scrambled by the SPS C-RNTI sent by the base station.
After correctly decoding a transport block on the PUSCH on the third carrier for the first time, the base station may send third bearer information on the PDCCH scrambled by the SPS C-RNTI for deactivating the uplink SPS resource on the previously used second carrier. The third bearer information on the SPS C-RNTI scrambled PDCCH may also be sent after consecutive correct decoding of M consecutive transport blocks on PUSCH on the third carrier for deactivating SPS resources on the previously used second carrier. Optionally, the base station may further set other conditions for triggering the base station to send the third bearer information on the PDCCH scrambled by the SPS C-RNTI, so as to deactivate the SPS resource on the previously used second carrier.
In this embodiment, after the radio channel quality of the current second carrier becomes poor, the base station may select a third carrier with better radio channel quality, and send the second bearer information on the PDCCH scrambled by the SPS C-RNTI to the UE, so that the UE activates the uplink SPS resource configured on the third carrier according to the second bearer information on the PDCCH, and sends the PUSCH on the third carrier through the uplink SPS resource according to the configuration information of the uplink SPS resource on the activated third carrier, that is, transmits the transport block of the uplink voice service through the PUSCH.
On the basis of the foregoing embodiment, there are multiple implementable manners for the base station to select the third carrier, and optionally, in this embodiment, the following two manners may be implemented:
the first mode is as follows:
before the step 103, the base station allocates Sounding Reference Signal (SRS) resources to the UE on each of the multiple first carriers;
and the base station informs the UE of the configuration information of the SRS resources on each first carrier through a special signaling. And after receiving the special signaling, the UE stores the configuration information of the SRS resource on each first carrier and feeds back a response message to the base station.
Preferably, the base station sends the configuration information of the SRS resource on each first carrier to the UE in step 102. The base station may send the configuration information of the SRS resource on each first carrier and the configuration information of the uplink SPS resource of each first carrier to the UE through the same dedicated signaling. After receiving the dedicated signaling, the UE stores the corresponding configuration information and feeds back only one response message to the base station.
The base station determines the wireless channel quality of the UE on each first carrier according to the SRS sent by the UE on each first carrier through the allocated SRS resource;
correspondingly, the selecting, by the base station, a third carrier from the plurality of first carriers includes:
and the base station selects the third carrier from the first carriers according to the wireless channel quality of the UE on each first carrier.
Specifically, the base station may allocate SRS resources to the UE on each first carrier on which the uplink SPS resources are configured. And the base station estimates the wireless channel quality of the UE on the corresponding first carrier according to the SRS sent by the UE on the first carrier through the SRS resource. When the third carrier needs to be selected, the base station may select one carrier with the best radio channel quality as the third carrier from the other first carriers except the second carrier according to the radio channel quality of each of the first carriers obtained most recently.
The second mode is as follows:
before the step 103, the base station sends PHR Report instruction information to the UE, where the instruction information is used to instruct the UE to Report Power Headroom Report (PHR) information of each first carrier;
and after receiving the indication information, the UE stores the indication information and feeds back a response message to the base station.
Preferably, the base station may send PHR report indication information to the UE in step 102.
Preferably, the base station may send the indication information and the configuration information of the uplink SPS resource of each first carrier to the UE through the same dedicated signaling. After receiving the dedicated signaling, the UE stores the corresponding configuration information and feeds back only one response message to the base station.
The base station determines the wireless channel quality of the UE on each first carrier according to the PHR information of each first carrier reported by the UE;
correspondingly, the selecting, by the base station, a third carrier from the first carriers includes:
and the base station selects the third carrier from the first carriers according to the wireless channel quality of the UE on each first carrier.
Specifically, after the base station sends PHR reporting indication information to the UE, the base station receives PHR information of each first carrier reported by the UE, the base station determines the radio channel quality of the UE on each first carrier according to the PHR information of each first carrier, and selects a carrier with the best radio channel quality from the other first carriers except the second carrier as the third carrier according to the radio channel quality of each first carrier obtained most recently when the third carrier needs to be selected.
In this embodiment, the quality of the wireless channel of the UE on the first carrier may be determined through the SRS or PHR information on the first carrier, so as to select an uplink carrier with better quality of the wireless channel for transmitting a transmission block of the uplink voice service of the UE.
On the basis of the foregoing embodiment, optionally, the method of this embodiment may further include:
the base station sends a first TPC command to the UE through a first PDCCH format scrambled by a first transmission power control-radio network temporary identifier (TPC-RNTI) of a first carrier where the currently activated uplink SPS resource is located; the first TPC command is used for controlling the power of a PUSCH of a first carrier where the currently activated uplink SPS resource is located;
correspondingly, before the base station sends the first TPC command to the UE through the first PDCCH format scrambled by the first TPC-RNTI of the first carrier of the currently activated uplink SPS resource, the method further includes:
before step 103, the base station determines configuration information of the first TPC command for each first carrier, and sends the configuration information of the first TPC command for each first carrier to the UE; the first TPC command configuration information for any of the first carriers includes: a first TPC-RNTI, a first TPC index and a first PDCCH format. The first PDCCH format is PDCCH format 3 or PDCCH format 3A.
And the UE stores the first TPC command configuration information of each first carrier wave sent by the base station and feeds back a response message to the base station.
Preferably, the base station may send the configuration information of the first TPC command for each first carrier to the UE in step 102.
Preferably, the base station may send the first TPC command configuration information of each first carrier and the uplink SPS resource configuration information of each first carrier to the UE through the same dedicated signaling. After receiving the dedicated signaling, the UE stores the corresponding configuration information and feeds back only one response message to the base station.
For a first carrier where a currently activated uplink SPS resource is located, configuration information of the first TPC command of the carrier is used for the UE to monitor a first PDCCH format scrambled by a first TPC-RNTI corresponding to the carrier on a downlink carrier of the special cell, and the transmission power of a PUSCH of the first carrier where the currently activated uplink SPS resource is located is adjusted according to the monitored first TPC command carried on the first PDCCH format.
Specifically, for the PUSCH transmitted through the uplink SPS resource, the PUSCH is a semi-persistent PUSCH, and power control of the semi-persistent PUSCH on each first carrier is independent from each other. The method for calculating the power of the semi-static PUSCH on each first carrier is the same as the method for calculating the power of the semi-static PUSCH in each cell in the existing 3GPP standard. Namely: according to the 3GPP standard, the method of calculating the transmit power of the semi-persistent PUSCH in the cell c may be used to calculate the transmit power of the semi-persistent PUSCH on the first carrier c in the present invention.
And the first TPC command of the semi-static PUSCH on each first carrier is carried to the UE through a corresponding PDCCH DCI format 3/3A. For an semi-static PUSCH on each first carrier, a base station determines a first TPC-RNTI carrying a first TPC command of the PUSCH and a first TPC index (TPC index, TPC index for short) corresponding to the first TPC command of the semi-static PUSCH in a PDCCH DCI format 3/3A scrambled by the first TPC-RNTI. The base station sends the first TPC command configuration information of each first carrier to the UE, where, for each first carrier, the first TPC command configuration information of the carrier includes: a first TPC-RNTI, a first TPC subscript, and a first PDCCH format (the first PDCCH format is DCI format 3 or DCI format 3A).
Preferably, the configuration information of the first TPC command for each first carrier is sent to the UE in the aforementioned step 102. The UE stores configuration information of the first TPC command of each first carrier and feeds back a response message to the base station. And then the UE monitors a first PDCCH DCI format scrambled by the corresponding first TPC RNTI according to the configuration information of the first TPC command of the carrier where the currently activated uplink SPS resource is positioned, and when the corresponding first PDCCH format is detected, the first TPC command on the first PDCCH format is obtained according to the corresponding first TPC subscript and is used for adjusting the transmission power of the PUSCH on the corresponding carrier.
The configuration information of the first TPC command for each first carrier may be different from each other, or may be completely the same. Since only one uplink SPS resource on the first carrier can be activated in the same subframe, it is preferable that the configuration information of the TPC command on each first carrier can be identical, that is: each first carrier has the same first TPC-RNTI, the same first TPC command index, and the same first PDCCH format. In this way, no matter which first carrier the currently activated uplink SPS resource is located on, the UE only needs to monitor the first PDCCH format scrambled by one fixed first TPC-RNTI to acquire the first TPC command thereon, so as to adjust the transmission power of the PUSCH on the first carrier of the currently activated uplink SPS resource.
Further, the method can also comprise the following steps:
the base station sends a second TPC command to the UE through a second PDCCH format scrambled by a second TPC-RNTI of each first carrier; the second TPC command is used for power control of the SRS on the first carrier. The second PDCCH format is PDCCH DCI format 3B. Correspondingly, before the base station sends the second TPC command for each first carrier to the UE through the second PDCCH format scrambled by the second TPC-RNTI for the first carrier, the method further includes:
before step 103, the base station determines configuration information of the second TPC command for each first carrier, and sends the configuration information of the second TPC command for each first carrier to the UE. And the UE stores the second TPC command configuration information of each first carrier wave sent by the base station and feeds back a response message to the base station. The second TPC command configuration information of each first carrier comprises; a second TPC-RNTI and a second TPC subscript.
Preferably, the base station may send the configuration information of the second TPC command for each first carrier to the UE in step 102.
Preferably, the base station may send the second TPC command configuration information of each first carrier and the uplink SPS resource configuration information of each first carrier to the UE through the same dedicated signaling. After receiving the dedicated signaling, the UE stores the corresponding configuration information and feeds back only one response message to the base station.
And then, the UE monitors a second PDCCH format scrambled by a second TPC-RNTI of each first carrier on a downlink carrier according to the configuration information of the second TPC command of the first carrier, and adjusts the SRS transmitting power of the first carrier according to the monitored second TPC command carried on the second PDCCH format.
Specifically, for each first carrier in which SRS resources are configured, the UE performs power control of SRS in units of carriers. The power control of SRS on each carrier is independent of each other. The method for calculating the SRS transmitting power on each first carrier by the UE is the same as the method for calculating the SRS power in each cell in the existing 3GPP standard. Namely: according to the 3GPP standard, the method of calculating the SRS transmit power in the cell c can be used to calculate the SRS transmit power on the first carrier c in the present invention.
For each first carrier configured with SRS resources, the base station determines a second TPC-RNTI carrying a second TPC command of the SRS on the first carrier and a second TPC command subscript TPC index corresponding to the second TPC command of the first carrier in the PDCCH DCI format 3B scrambled by the second TPC-RNTI. The base station sends the second TPC command configuration information of each first carrier to the UE, where, for each first carrier, the second TPC command configuration information of the carrier includes: a second TPC-RNTI and a second TPC subscript.
Preferably, the base station sends the configuration information of the second TPC command for SRS on each first carrier to the UE in step 102. The UE saves the received configuration information of the second TPC command on each first carrier. And then, the UE monitors the PDCCH DCI format 3B scrambled by the corresponding second TPC RNTI according to the configuration information of the second TPC command of each first carrier, and obtains the second TPC command corresponding to the second TPC command subscript on the UE for adjusting the SRS transmitting power on the corresponding first carrier. Here, the configuration information of the second TPC command differs from one first carrier to another. Only then can the second TPC commands of the SRS on a different first carrier be distinguished.
Further, for each first carrier, if there is a PUSCH transmission on the carrier, the SRS power on the first carrier may be adjusted according to the first TPC command on the PUSCH on the carrier. In this scenario, the base station may not transmit the second TPC command configuration information for the first carrier.
Of course, in the above scenario, the SRS power control on the first carrier may be made independent of the PUSCH power control on the carrier, and the base station sends the second TPC command configuration information to the carrier, so that the UE performs the SRS power control on the carrier independently according to the second TPC command configuration information.
