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

1.1 frame Structure

To support various frequency bands and deployment scenarios, NR (New Radio, New air interface) supports flexible numerology configuration. One numerology (denoted with μ) corresponds to one SCS configuration (and cyclic prefix length) on the frequency domain. In NR, the signal is generated by multiplying the basic SCS (15kHz) by an integer N (i.e., by N-fold)ⁿN is an integer), a variety of different numerologies are defined. As shown in table one:

watch 1

As shown in table one, as the SCS increases, the number of slots (slots) included on each subframe increases, and the time occupied by each slot decreases.

1.2PDCCH

The PDCCH (Physical Downlink Control Channel) is a Downlink Control Channel and carries Control Information DCI (Downlink Control Information) of a PUSCH (Physical Uplink Share Channel) and a PDSCH (Physical Downlink Share Channel). In LTE, the PDCCH occupies the entire bandwidth in the frequency domain and the first 1-3 symbols of each subframe in the time domain. In NR, if the PDCCH continues to occupy the whole Bandwidth in LTE, it is not clear that resources are wasted, and it may put high requirements on the UE, which is not beneficial to reduce the cost of the UE, so the PDCCH in NR may be in BWP (Bandwidth Part), and the time domain does not occupy fixed time slots. In NR, one PDSCH is scheduled for one PDCCH so far. PDCCH time-frequency resources in NR are mainly determined by core-resource set (Control-resource set) and Search Space (SS).

1.2.1CORESET

CORESET addresses the existing range problem of PDCCH, such as time domain length and frequency domain range. Because the system bandwidth of NR is large (400M maximum), if the static configuration mode of LTE (occupying the whole system bandwidth) is used, blind detection complexity is greatly increased. Therefore, NR employs configurable CORESET, and the time domain length and frequency domain range of CORESET can be configured by system information or dedicated RRC (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, which aims to reduce the blind detection complexity of the UE as much as possible. Unlike LTE, for a certain core space in NR, NR may configure different search spaces for different UEs, that is, different blind detection modes (such as monitoring period, monitored symbol start position, etc.) for different UEs. Therefore, the blind detection complexity of the UE can be further reduced.

1.2.3DCI

The UE knows the CORESET and Search space configuration of the UE and finds the PDCCH sent to the UE, thereby solving the content carried by the PDCCH, namely the DCI. DCI is divided into different formats as shown in table two:

watch two

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

1 distinguishing mark: 1bit

2 frequency domain resource allocation domain

3 time domain resource allocation domain: 4bits

4 mapping of VRBs to PRBs: 1bits

5 modulation coding scheme: 5bits

6 New data indicates: 1bits

The following describes in detail a channel scheduling method provided in the embodiments of the present application with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Fig. 2 is a flowchart illustrating a channel scheduling method according to 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 equipment determines the slot number and the slot position occupied by one or more target channels scheduled by a first channel;

s220, the communication device determines the number of symbols and the symbol position occupied by the target channel in each slot occupied.

It should be noted that the execution subject of the method may be a communication device, such as a terminal or a network side device. The following describes the technical solution of the present application in detail by taking the communication device as an example to execute the above method.

Firstly, the communication device may determine the slot number and slot position occupied by the target channel scheduled by the first channel; the communication device may then determine the number of symbols and the symbol position that the target channel occupies in each slot occupied.

The first channel may be a channel having a channel scheduling function, such as PDCCH or PUCCH. Wherein, the PDCCH may schedule the PDSCH, and the PUCCH may schedule the 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.

According to the channel scheduling method provided by the embodiment of the application, because the first channel can schedule one or more target channels, compared with the technical scheme that only one channel can be scheduled at a time in the prior art, the complexity of channel scheduling can be remarkably reduced, so that the energy consumption of communication equipment is reduced, and the communication efficiency of the communication equipment is improved.

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

one target channel occupies a plurality of slots;

each target channel of the plurality of target channels occupies a slot.

When the target channel scheduled by the first channel is one, the target channel may occupy a plurality of slots, e.g., 3, 5, etc. The number of slots occupied by the slot may be adjusted according to actual situations, which is not specifically limited in this embodiment of the present application.

For example, when the target channel needs to occupy a large time domain resource, the number of slots it occupies may be, for example, 8; when the target channel needs to occupy a small time domain resource, the number of slots it occupies may be, for example, 2.

When the number of the target channels scheduled by the first channel is multiple, each target channel in the multiple target channels occupies one slot respectively. For example, when the first channel schedules 6 target channels, the 6 target channels occupy one slot each, and occupy 6 slots in total.

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

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

mode 1: determining the slot number according to the first slot number indicated by the link control information;

the link Control Information may include DCI or UCI (Uplink Control Information).

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

And when the first channel is the PUCCH, the communication device may parse first slot number information included in the UCI related indication field, and use the first slot number as the slot number.

Mode 2: determining the slot number according to a second slot number contained in a TDRA (Time Domain Resource Assignment) entry (configuration table) configured by a radio Resource control RRC;

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

Mode 3: determining the slot number according to a third slot number predefined by a protocol or preconfigured by a network;

the communication device may take a third slot number, either predefined by the protocol or pre-configured by the network, as the slot number.

Mode 4: determining the slot number according to the subcarrier interval SCS of the first channel or the SCS of the target channel;

alternatively, the mode 4 may include any one of:

mode 41: determining the slot number according to the preset corresponding relation between the SCS of the first channel or the SCS of the target channel and the slot number;

the preset corresponding relationship between the SCS of the first channel or the SCS of the target channel and the slot number may be, for example:

when SCS is 480K, the slot number is 4; when SCS is 960K, the slot number is 8; alternatively, the first and second liquid crystal display panels may be,

when SCS is 480K, the slot number is 6; when SCS is 960K, slot number is 12.

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

Mode 42: the slot number is determined based on 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 the specific size thereof may be adjusted according to actual needs, which is not specifically limited in this embodiment of the application.

For example, when the SCS of the first channel is 960K, and the quotient thereof with the reference SCS is 960/120-8, the slot number may 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 result after calculation as the slot number.

For example, the coefficient may be a positive integer, e.g. 2, and when the SCS of the first channel is 960K, the slot number may be 8 × 2-16, or 8+ 2-10.

Mode 5: determining the slot number according to the second slot number and a preset parameter;

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

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

For example, when the second slot number is 6 and the preset parameter is 3, the slot number is 6 × 3 — 18 when the product of the second slot number and the preset parameter is the slot number; when the sum of the second slot number and the preset parameter is the slot number, the slot number is 6+ 3-9; when the quotient of the second slot number and the preset parameter is the slot number, the slot number is 6 ÷ 3 ═ 2.

Mode 6: and determining the slot number according to the SCS of the first channel or the SCS of the target channel and the second slot number.

Optionally, the method 6 may include:

determining a ratio of the SCS of the first channel or the SCS of the target channel to a reference SCS; the slot number is determined based on the product of the ratio and the second slot number.

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

If the second slot number is 4, the product of the ratio and the second slot number is 4 × 4 to 16. The slot number may be taken as the product 16 of the above ratio and the second slot number.

Optionally, a correction parameter may be set, which may be a positive or 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 taken as the slot number.

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

According to the channel scheduling method provided by the embodiment of the application, the slot number occupied by the target channel is determined through the various modes, the determined slot number occupied by the target channel can be guaranteed to be reasonable in various application scenes, and the applicability of the channel scheduling method provided by the embodiment of the application in various application scenes is effectively improved.

In one embodiment, in the case that slots occupied by one or more target channels scheduled by a first channel are discontinuous, N slots are used for target channel transmission in M slots, and the positions of the N slots are predefined by a protocol, or preconfigured by a network side, or determined according to a preset rule;

wherein, M is the slot number which can be used for target channel transmission at present, and N is the slot number; m is greater than N.

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

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

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

taking the first slot and the last slot of the M slots as the slots occupied by the target channel, and randomly distributing the slots occupied by the other target channels to other slots except the first slot and the last slot of the M slots;

or, one or two middle slots located in the middle position in the M slots are used as slots occupied by the target channel, and the slots occupied by the rest target channels are randomly distributed to the other slots except the middle slot in the M slots;

or, according to the size of the priority of each slot in the M slots, selecting the first N slots as the slots occupied by the target channel; the priority may be determined by a location of a slot in a radio frame or a radio subframe or a slot bundling (including multiple slots), or by a current symbol occupancy of a slot, and the like.

The foregoing is merely an example of the preset rule, and the specific content of the preset rule may be adjusted according to actual needs, which is not specifically limited in this embodiment of the application.

In one embodiment, in the case that the first channel schedules a target channel, step S220 may include:

s2201, determining the number of symbols and the positions of the symbols occupied by the target channel in each slot occupied according to the link control information and/or the number of the slots.

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

operation 1: determining the number of symbols and the positions of the symbols occupied by the target channel in each slot occupied by the target channel according to the information of the starting symbols carried by the link control information and the length of the continuous symbols of the whole target channel;

the link control information may carry information of a start symbol (start symbol) and a length of an entire target channel sustain symbol.

The communication device may determine the position of the starting symbol occupied by the target channel based on the information of the starting symbol.

For example, the indication field in the link control information indicates that the starting symbol of the target channel is 5, and the length of the whole target channel persistent symbol is 60. The target channel starts with the 5 th symbol in the first slot and occupies subsequent symbols in turn (if the symbol in the current slot is full, the symbol in the next slot continues to be occupied, and so on) until the number of occupied symbols reaches 60, as shown in fig. 3.

As can be seen from fig. 3, the number of symbols and the symbol position occupied by the target channel in each slot can be directly determined by the information of the starting symbol carried by the link control information and the length of the continuous symbol of the entire target channel.

And operation 2: and determining the number of occupied symbols and the positions of the symbols of the target channel in each occupied slot according to the information of the starting symbol and the information of the ending symbol carried by the link control information and the slot number.

For example, the indication field in the link control information indicates a start symbol, e.g., the 5 th symbol, of the target channel and an end symbol, e.g., the 9 th symbol, of the target channel. The target channel occupies subsequent symbols in sequence from the 5 th symbol in the first slot (if the symbol in the current slot is full, the symbol in the next slot is occupied continuously, and so on); and combining the slot numbers, such as 5, to obtain the target channel occupying the 9 th symbol in the 5 th slot. As shown in fig. 3.

As can be seen from fig. 3, by combining the information of the start symbol and the information of the end symbol carried by the link control information with the slot number, the number of symbols and the symbol position occupied by the target channel in each slot occupied can be directly determined.

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

s2202, according to the link control information and the slot number, determining the symbol number and the symbol position occupied by the target channel in each occupied slot.

Alternatively, the specific operation of step S2202 may include any one of:

operation I: determining that the time domain resource positions of all the other target channels in the corresponding slots thereof are consistent with the TDRA information of the first target channel by combining the slot number according to the TDRA information of the first target channel carried in the link control information;

in operation I, the link control information may only carry the TDRA information of the first target channel, and in combination with the slot number, the time domain resource positions of all subsequent default remaining target channels in the corresponding slots are consistent with the TDRA information of the first target channel.

Wherein the TDRA information may include a number of symbols occupied by the target channel and location information. And under the condition that the slot position occupied by the target channel is determined, the target channel can occupy corresponding symbols in the corresponding slots according to the TDRA information.

For example, 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 (occupied symbol numbers and symbol positions) of the subsequent 4 target channels in the corresponding slots are 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 slots occupied by the target channel is shown in fig. 4; an example of the slot occupied by the target channel in the case where the slot occupied by the target channel is discontinuous is shown in fig. 5.

Operation II: according to a first number of TDRA carried by the link control information or list entry containing the first number of TDRA, determining that the first number of target channels follow the TDRA indication, wherein time domain resource positions of all subsequent target channels in corresponding slots are the same as one or more TDRA in the first number of TDRA, and the one or more TDRA is predefined or preconfigured;

the first number may be, for example, 2, 3, and the like, and the specific size may be adjusted according to actual situations, which is not specifically limited in this embodiment of the 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 indication of 2 TDRAs, that is, the first target channel can follow the indication of the first TDRA, and occupy symbols in the corresponding slot according to the number of symbols occupied by the target channels included in the first TDRA and the position information; and the second target channel may occupy symbols within the corresponding slot according to the number of symbols occupied by the target channel included in the second TDRA and the position information, following the indication of the second TDRA.

The subsequent 3-5 th target channels can occupy the same time domain resource position as the time domain resource position occupied by the first or second target channel in the corresponding slot with reference to the occupied time domain resource position (occupied symbol number and position) of the first or second target channel.

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

In the case where the target channel is discontinuous (does not occupy all symbols within the corresponding slot), and the slot occupied by the target channel is continuous, an example of the slot occupied by the target channel is shown in fig. 6; in the case where the target channel is discontinuous and the slot occupied by the target channel is discontinuous, an example of the slot occupied by the target channel is shown in fig. 7; in the case where the target channel is continuous (occupies all symbols within the corresponding slot), and the slot occupied by the target channel is continuous, an example of the slot occupied by the target channel is shown in fig. 8; in the case where the target channel is continuous and the slot occupied by the target channel is discontinuous, an example of the slot occupied by the target channel is shown in fig. 9.

Operation III: and determining the number of symbols occupied by the target channel in each slot occupied by the target channel according to the information of the starting symbol and the information of the ending symbol carried by the link control information and the slot number.

For example, the first channel schedules 5 target channels, the link control information carries information of a start symbol and information of an end symbol, for example, the start symbol information may indicate that the 5 th symbol is the start symbol, and the end symbol information may indicate that the 9 th symbol is the end symbol. The first target channel is occupied starting with the 5 th symbol of the corresponding slot until the last symbol, e.g., the 14 th symbol, of the slot is occupied. The subsequent second, third and fourth target channels occupy all symbols in the corresponding slot, and the last fifth target channel occupies the 1 st to 9 th symbols in the corresponding slot.

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

The channel scheduling method provided by the embodiment of the application determines the number of symbols and the positions of the symbols occupied by the target channel in the corresponding slot through the various manners, so that the determined number of symbols and positions of the symbols occupied by the target channel are reasonable in various application scenes, and the applicability of the channel scheduling method provided by the embodiment of the application in various application scenes is effectively improved.

It should be noted that, in the scheduling method for a channel provided in the embodiment of the present application, the execution subject may be a scheduling apparatus for a channel, or a control module in the scheduling apparatus for a channel, which is used for executing the scheduling method for a channel.
