However, the following description describes a New Radio (NR) system for example purposes, and NR terminology is used in most of the description below, although these techniques are also applicable to applications other than NR system applications, such as 6th generation ( 6th ^Generation , 6G) communication system.

FIG. 1 shows a structural diagram of a wireless communication system to which an embodiment of the present application can be applied. The wireless communication system includes a terminal 11 and a network-side device 12 . The terminal 11 may also be called a terminal device or a user terminal (User Equipment, UE), and the terminal 11 may be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer) or a notebook computer, a personal digital assistant (Personal Digital Assistant, PDA), handheld computer, netbook, ultra-mobile personal computer (ultra-mobile personal computer, UMPC), mobile Internet Device (Mobile Internet Device, MID), wearable device (Wearable Device) or vehicle-mounted device ( VUE), pedestrian terminal (PUE) and other terminal-side devices, wearable devices include: bracelets, earphones, glasses, etc. It should be noted that, the embodiment of the present application does not limit the specific type of the terminal 11 .

The base station in the NR system is taken as an example, but the specific type of the base station is not limited.

In order to more fully understand the technical solutions provided by the embodiments of the present application, the following contents are now introduced:

1.1 Frame structure

In order to support various frequency bands and deployment scenarios, NR (New Radio, new air interface) supports flexible numerology configurations. A numerology (denoted by μ) corresponds to an SCS configuration (and cyclic prefix length) in the frequency domain. In NR, by multiplying the base SCS (15 kHz) by an integer N (ie expanding by a factor of N. N=2 ⁿ , where n is an integer), a number of different numerologies are defined. As shown in Table 1:

Table I

As shown in Table 1, as the SCS increases, the number of slots (time slots) included in each subframe increases exponentially, while the time occupied by each slot decreases exponentially.

1.2PDCCH

PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) is a downlink control channel, which carries the control information DCI (Downlink Control Channel) of PUSCH (Physical Uplink Share Channel, Physical Uplink Share Channel) and PDSCH (Physical Downlink Share Channel, Physical Downlink Share Channel). Information, downlink control information). In LTE, the PDCCH occupies the entire bandwidth in the frequency domain, and occupies the first 1-3 symbols of each subframe in the time domain. In NR, if the PDCCH continues to occupy the entire bandwidth in the LTE method, it will undoubtedly be a waste of resources, and it will put high requirements on the UE, which is not conducive to reducing the cost of the UE. set bandwidth), and the time domain does not occupy a fixed number of time slots. In NR, one PDSCH is scheduled by one PDCCH so far. The PDCCH time-frequency resources in NR are mainly determined by CORESET (Control-resource set, control resource set) and search space (Search Space, SS).

1.2.1 CORESET

CORESET solves the problem of the existence range of PDCCH, such as time domain length and frequency domain range. Since the system bandwidth of NR is very large (maximum 400M), if the static configuration method of LTE is used (occupying the entire system bandwidth), the complexity of blind detection will be greatly increased. Therefore, the NR adopts a configurable CORESET, and the time domain length and frequency domain range of the CORESET can be configured through system information or a dedicated RRC (Radio Resource Control, radio resource control) message.

1.2.2Search space

The Search space solves the problem of how the UE searches. There is a similar concept in LTE, the purpose of which is to reduce the blind detection complexity of the UE as much as possible. Different from LTE, the search space in NR is for a certain CORESET, and NR can configure different search spaces for different UEs, that is, different blind detection methods are configured for different UEs (such as monitoring period, monitoring symbol starting position, etc.). Thus, the blind detection complexity of the UE can be further reduced.

1.2.3 DCI

The UE knows its own CORESET and Search space configuration, finds the PDCCH sent to itself, and thus solves the content carried by the PDCCH channel, that is, the downlink control information DCI. DCI is divided into different formats, as shown in Table 2:

Table II

The content contained in different DCI formats is inconsistent. Take DCI 1-0 as an example:

1 distinction mark: 1bit

2 Frequency Domain Resource Allocation Domain

3 Time domain resource allocation domain: 4bits

4VRB to PRB mapping: 1bits

5 modulation coding scheme: 5bits

6 new data indication: 1bits

7 redundant version: 2bits

8HARQ process indication: 4bits

9 Downlink allocation indication: 2bits

10PUCCH power control signaling: 2bits

11PUCCH resource indication: 3bits

12HARQ feedback timing indication: 3bits

The channel scheduling method provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios.

FIG. 2 is a schematic flowchart of a channel scheduling method provided by an embodiment of the present application. As shown in FIG. 2 , an embodiment of the present application provides a channel scheduling method, which may include:

S210, the communication device determines the number of slots and slot positions occupied by one or more target channels scheduled by the first channel;

S220. The communication device determines the number of symbols and symbol positions occupied by the target channel in each occupied slot.

It should be noted that the execution body of the above method may be a communication device, such as a terminal or a network side device. The technical solution of the present application will be described in detail below by taking a communication device performing the above method as an example.

First, the communication device can determine the number of slots and slot positions occupied by the target channel scheduled by the first channel; then, the communication device can determine the number of symbols and symbol positions occupied by the target channel in each occupied slot.

The first channel may be a channel with a channel scheduling function, such as PDCCH or PUCCH. Wherein, PDCCH can schedule PDSCH, and PUCCH can schedule PUSCH.

The target channel may be a channel scheduled by the first channel, for example, when the first channel is PDCCH, the target channel may be PDSCH, and when the first channel is PUCCH, the target channel may be PUSCH.

In the channel scheduling method provided by the embodiments of the present application, since the first channel can schedule one or more target channels, the complexity of channel scheduling can be significantly reduced compared to the technical solution in which only one channel can be scheduled at a time in the prior art , thereby reducing the energy consumption of the communication device and improving the communication efficiency of the communication device.

In one embodiment, the manner in which the target channel occupies the slot may include any of the following:

A target channel occupies multiple slots;

Each target channel in the multiple target channels occupies a slot.

When there is one target channel scheduled by the first channel, the target channel may occupy multiple slots, such as 3, 5 and so on. The number of slots occupied by the slot can be adjusted according to the actual situation, which is not specifically limited in this embodiment of the present application.

For example, when the target channel needs to occupy larger time domain resources, the number of slots it occupies can be, for example, 8; when the target channel needs to occupy smaller time domain resources, the number of slots it occupies can be, for example, 2 .

When there are multiple target channels scheduled by the first channel, each of the multiple target channels occupies a slot respectively. For example, when the first channel schedules 6 target channels, the 6 target channels occupy one slot respectively, occupying 6 slots in total.

The number of the multiple target channels may be adjusted according to the actual situation, which is not specifically limited in this embodiment of the present application.

In one embodiment, determining the number of slots occupied by one or more target channels scheduled by the first channel may include any of the following methods:

Mode 1: Determine the number of slots according to the first number of slots indicated by the link control information;

The link control information may include DCI or UCI (Uplink Control Information, uplink control information).

When the first channel is the PDCCH, the communication device can parse out the first slot number information included in the relevant indication field of the DCI, and use the first slot number as the slot number.

When the first channel is PUCCH, the communication device can parse out the first slot number information included in the relevant indication field of the UCI, and use the first slot number as the slot number.

Mode 2: Determine the number of slots according to the second number of slots included in the TDRA (Time Domain Resource Assignment, Time Domain Resource Assignment) entry (configuration table) configured by the radio resource control RRC;

The communication device may identify the second slot number information included in the TDRA entry configured by the RRC for the communication device, and use the second slot number as the slot number.

Mode 3: Determine the number of slots according to the third slot number predefined by the protocol or preconfigured by the network;

The communication device may use the third slot number predefined by the protocol or preconfigured by the network as the slot number.

Mode 4: Determine the number of slots according to the subcarrier spacing SCS of the first channel or the SCS of the target channel;

Optionally, Mode 4 may include any of the following:

Mode 41: Determine the number of slots according to the SCS of the first channel or the preset correspondence between the SCS of the target channel and the number of slots;

The preset correspondence between the SCS of the first channel or the SCS of the target channel and the number of slots may be, for example:

When SCS=480K, the number of slots is 4; when SCS=960K, the number of slots is 8; or,

When SCS=480K, the number of slots is 6; when SCS=960K, the number of slots is 12 and so on.

The preset corresponding relationship may be adjusted according to actual needs, which is not specifically limited in this embodiment of the present application.

Manner 42: Determine the number of slots according to the SCS of the first channel or the quotient of the SCS of the target channel and the reference SCS.

The size of the reference SCS may be, for example, 120K, and its specific size may be adjusted according to actual needs, which is not specifically limited in this embodiment of the present application.

For example, when the SCS of the first channel is 960K, and the quotient of the SCS and the reference SCS is 960/120=8, the number of slots can be determined to be 8.

Of course, it is also possible to multiply the SCS of the first channel or the quotient of the SCS of the target channel and the reference SCS by a certain coefficient, or add a certain coefficient, and use the calculated result as the slot number.

For example, the coefficient may be a positive integer, such as 2, and when the SCS of the first channel is 960K, the number of slots may be 8×2=16, or 8+2=10.

Method 5: Determine the number of slots according to the second slot number and preset parameters;

The preset parameter is a positive integer, which can be, for example, 3, and its specific size can be adjusted according to actual needs, which is not specifically limited in this embodiment of the present application.

After the second slot number and the preset parameter are determined, the product or sum or quotient of the second slot number and the preset parameter may be used as the slot number.

For example, when the second slot number is 6 and the preset parameter is 3, when the product of the second slot number and the preset parameter is the slot number, the slot number is 6×3=18; When the sum of the parameters is the number of slots, the number of slots is 6+3=9; when the quotient of the second number of slots and the preset parameter is the number of slots, the number of slots is 6÷3=2.

Manner 6: The number of slots is determined according to the SCS of the first channel or the SCS of the target channel, and the number of the second slots.

Optionally, way 6 may include:

Determine the ratio of the SCS of the first channel or the SCS of the target channel to the reference SCS; determine the number of slots according to the product of the ratio and the second number of slots.

For example, when the SCS of the first channel or the SCS of the target channel is 480K and the reference SCS is 120K, the ratio of the SCS of the first channel or the SCS of the target channel to the reference SCS is 480:120=4.

If the second slot number is 4, the product of the above ratio and the second slot number is 4×4=16. The product of the above ratio and the second slot number 16 can be used as the slot number.

Optionally, a correction parameter may also be set, and the correction parameter may be a positive integer or a negative integer, such as -2 or 2, and the sum of the product of the above ratio and the second slot number and the correction parameter is used as the slot number.

For example, when the correction parameter is -2, the product of the above ratio and the second slot number, 16, and the sum of the correction parameter -2, 14, can be used as the slot number.

In the channel scheduling method provided by the embodiments of the present application, the number of slots occupied by the target channel is determined through the above various methods, which can ensure that the determined number of slots occupied by the target channel is reasonable in various application scenarios, which effectively improves the The applicability of the channel scheduling method provided by the embodiment of the present application in various application scenarios is discussed.

In one embodiment, when the slots occupied by one or more target channels scheduled by the first channel are discontinuous, there are N slots in the M slots for target channel transmission, and the N slots are used for transmission of the target channel. The location is predefined by the protocol, or preconfigured by the network side, or determined according to preset rules;

Among them, M is the number of slots that can currently be used for target channel transmission, and N is the number of slots; M is greater than N.

After the communication device determines the number M of slots that can currently be used for target channel transmission, it can use N slots among the M slots as the slots occupied by the target channel according to the provisions of the protocol. Among them, the protocol can stipulate that, for example, the first slot and the last slot in the M slots must be used as the slots occupied by the target channel, and the slots occupied by the remaining target channels can be randomly assigned to the M slots except the first slot. one slot and other slots other than the last slot; alternatively, the protocol may specify that, for example, one or two middle slots in the middle of the M slots must be used as the slots occupied by the target channel, and the remaining target The slot occupied by the channel can be randomly allocated to other slots except the middle slot among the M slots.

The communication device may also determine N slots among the M slots as the slots occupied by the target channel according to the pre-configuration of the network.

The communication device may also use N slots among the M slots as the slots occupied by the target channel according to an allocation result determined by the network according to a preset rule. The preset rules can include, for example:

The first slot and the last slot in the M slots are used as the slots occupied by the target channel, and the slots occupied by the remaining target channels are randomly assigned to the M slots except the first slot and the last slot. in other slots of ;

Alternatively, one or two middle slots located in the middle of the M slots are used as the slots occupied by the target channel, and the slots occupied by the remaining target channels are randomly allocated to the M slots except the middle slot. slot;

Alternatively, according to the priority of each of the M slots, the first N slots are selected as the slots occupied by the target channel; , including the location determination in multiple slots), or determined by the current symbol occupancy rate of the slot, etc.

The above is only an example of the preset rule, and the specific content of the preset rule can be adjusted according to actual needs, which is not specifically limited in this embodiment of the present application.

In one embodiment, when the first channel schedules a target channel, step S220 may include:

S2201. Determine the number of symbols and symbol positions occupied by the target channel in each slot occupied by the target channel according to the link control information and/or the number of slots.

Optionally, the specific operation of step S2201 may include any of the following:

Operation 1: According to the information of the start symbol carried by the link control information and the length of the continuous symbol of the entire target channel, determine the number of symbols and symbol positions occupied by the target channel in each occupied slot;

The link control information may carry the information of the start symbol and the length of the continuation symbol of the entire target channel.

The communication device may determine the position of the start symbol occupied by the target channel according to the information of the start symbol.

For example, the indication field in the link control information indicates that the start symbol of the target channel is 5, and the length of the continuation symbol of the entire target channel is 60. Then the target channel starts from the 5th symbol in the first slot, and occupies subsequent symbols in turn (if the symbols in the current slot are full, it continues to occupy the symbols in the next slot, and so on), until the occupied The number of symbols reaches 60, as shown in Figure 3.

It can be seen from FIG. 3 that the number of symbols and symbol positions occupied by the target channel in each slot can be directly determined by the information of the start symbol carried by the link control information and the length of the continuous symbol of the entire target channel.

Operation 2: According to the information of the start symbol and the information of the end symbol carried by the link control information, combined with the number of slots, determine the number of symbols and symbol positions occupied by the target channel in each occupied slot.

For example, the indication field in the link control information indicates the start symbol of the target channel, such as the 5th symbol, and the end symbol of the target channel, such as the 9th symbol. Then the target channel starts from the 5th symbol in the first slot, and occupies subsequent symbols in turn (if the symbols in the current slot are full, it continues to occupy the symbols in the next slot, and so on); number, such as 5, the target channel occupies the 9th symbol in the 5th slot. As shown in Figure 3.

It can be seen from FIG. 3 that the number of symbols and symbol positions occupied by the target channel in each slot occupied by the target channel can be directly determined through the information of the start symbol and the information of the end symbol carried by the link control information, combined with the number of slots.

In one embodiment, in the case of determining the number of slots and slot positions occupied by multiple target channels scheduled by the first channel, step S220 may include:

S2202. Determine the number of symbols and symbol positions occupied by the target channel in each occupied slot according to the link control information and the number of slots.

Optionally, the specific operation of step S2202 may include any of the following:

Operation I: According to the TDRA information of the first target channel carried in the link control information, combined with the number of slots, determine that the time domain resource positions of all the remaining target channels in their corresponding slots are consistent with the TDRA information of the first target channel ;

In operation 1, the link control information may only carry the TDRA information of the first target channel, combined with the number of slots, the subsequent default time domain resource positions of all remaining target channels in the corresponding slots and the TDRA information of the first target channel Consistent.

The TDRA information may include the number of symbols occupied by the target channel and location information. In the case where the slot position occupied by the target channel is determined, the target channel can occupy the corresponding symbol in the corresponding slot according to the TDRA information.

For example, if the first channel schedules 5 target channels, the link control information only needs to carry the TDRA information of the first target channel, and the time domain resource positions (the number of occupied symbols and symbols of the following 4 target channels in the corresponding slot) location) is consistent with the TDRA information of the first target channel.

In the case where the slots occupied by the target channel are continuous, an example of the slot occupied by the target channel is shown in Figure 4; when the slots occupied by the target channel are discontinuous, an example of the slot occupied by the target channel is shown in Figure 5.

Operation II: According to the first number of TDRAs carried by the link control information, or the list entry that indicates the first number of TDRAs, determine that the first number of target channels follow the TDRA instruction, and all subsequent target channels are in the corresponding slot. The time domain resource location is the same as one or more TDRAs in the first number of TDRAs, and the one or more TDRAs are predefined or preconfigured;

The first number may be, for example, 2, 3, etc., and the specific size may be adjusted according to the actual situation, which is not specifically limited in this embodiment of the present application.

Assuming that the first channel schedules 5 target channels and the first number is 2, the first 2 of the 5 target channels follow the instructions of the two TDRAs, that is, the first target channel can follow the instructions of the first TDRA, according to The number of symbols occupied by the target channel included in the first TDRA and the position information to occupy the symbols in the corresponding slot; while the second target channel can follow the instructions of the second TDRA, according to the target channel included in the second TDRA. The number of symbols and position information to occupy the symbols in the corresponding slot.

The subsequent 3-5 target channels can refer to the time-domain resource position (the number and position of occupied symbols) occupied by the first or second target channel, and occupy the corresponding slot with the first or second target channel. The time domain resource location occupied by the target channel is the same as the time domain resource location.

For example, the second target channel occupies the 3rd to 12th symbols in the corresponding slot, and the third target channel, the fourth target channel and the fifth target channel also occupy the 3rd to 12th symbols in the corresponding slot.

When the target channel is discontinuous (does not occupy all symbols in the corresponding slot), and the slots occupied by the target channel are continuous, an example of the target channel occupying the slot is shown in Figure 6; When the occupied slots are discontinuous, an example of the target channel occupying the slot is shown in Figure 7; when the target channel is continuous (occupying all symbols in the corresponding slot), and the target channel occupies continuous slots, the target channel occupies An example of a slot is shown in FIG. 8 ; when the target channel is continuous and the slots occupied by the target channel are discontinuous, an example of the slot occupied by the target channel is shown in FIG. 9 .

Operation III: According to the information of the start symbol and the information of the end symbol carried by the link control information, combined with the number of slots, determine the number of symbols occupied by the target channel in each occupied slot.

For example, the first channel schedules 5 target channels, and the link control information carries the information of the start symbol and the information of the end symbol. For example, the start symbol information may indicate that the 5th symbol is the start symbol, and the end symbol information may indicate the 9th symbol is the end symbol. The first target channel is occupied from the 5th symbol of the corresponding slot until the last symbol of the slot, eg, the 14th symbol. The subsequent second target channel, third target channel, and fourth target channel occupy all symbols in the corresponding slot, and the final fifth target channel occupies the first symbol to the ninth symbol in the corresponding slot.

In the case where the slots occupied by the target channel are continuous, an example of the slot occupied by the target channel is shown in Figure 10; when the slots occupied by the target channel are discontinuous, an example of the slot occupied by the target channel is shown in Figure 11.

In the channel scheduling method provided by the embodiments of the present application, the number of symbols and symbol positions occupied by the target channel in the corresponding slot are determined in the above-mentioned various ways, which can ensure the number of symbols occupied by the determined target channel in various application scenarios. And the symbol position is reasonable, which effectively improves the applicability of the channel scheduling method provided by the embodiment of the present application in various application scenarios.
