Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the invention. Rather, they are merely examples of apparatus and methods consistent with aspects of the invention as detailed in the accompanying claims.

The terminology used in the present disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used in this disclosure and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any or all possible combinations of at least one of the associated listed items.

It should be understood that although the terms first, second, third, etc. may be used in this disclosure to describe various information, these information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure. The word "if" as used herein may be interpreted as "at … …" or "at … …" or "responsive to a determination", depending on the context.

Currently, the time-frequency resources for NR-PDCCH transmission can be determined by the following parameters:

parameter 1, CORESET

CORESET is used to indicate the number of orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbols occupied by NR-PDCCH transmissions and the Resource Block (RB) location occupied by the frequency domain.

Specifically, the base station indicates RBs occupied by CORESET in the frequency domain with 6 RBs as granularity through a bitmap (bitmap) having a length of 45 bits (bits).

The base station indicates the number of symbols occupied by CORESET in the time domain by a duration (duration) parameter, for example, 1 to 3 OFDM symbols are occupied.

Parameter 2, search Space (SS)

The SS parameters determine the absolute time domain position of the time-frequency resource occupied by the NR-PDCCH transmission.

When the downlink resource in the DL slot (slot) is divided into two or more discontinuous segments by UL subband, as shown in fig. 1, since the frequency domain resource allocation of CORESET is in granularity of 6 RBs, there may be a portion of CORESET resources located inside the UL subband, so that the overlapping portion of resources cannot be used for transmitting the NR-PDCCH, which results in a decrease in transmission performance of the NR-PDCCH.

In order to solve the technical problems, the present disclosure provides a channel transmission method and apparatus, and a storage medium. The transmission performance of the PDCCH can be prevented from being reduced, and the reliability of full duplex communication is improved.

The channel transmission method provided by the present disclosure is first introduced from the terminal side.

An embodiment of the present disclosure provides a channel transmission method, referring to fig. 2, fig. 2 is a flowchart of a channel transmission method, which may be performed by a terminal, according to an embodiment, and the method may include the following steps:

In step 201, in response to the control resource set CORESET overlapping the first resource set occupied by the uplink sub-band, a resource set occupied by the physical downlink control channel PDCCH is determined.

In the embodiment of the present disclosure, the uplink sub-band is located on a time unit whose transmission direction is downlink or variable.

The time unit may be a seamless bidirectional forwarding detection (Seamless Bidirectional Forwarding Detection, SBFD) time unit. The SBFD time unit is a time unit on which information transmission in different transmission directions can be performed.

In the embodiments of the present disclosure, the SBFD time unit may particularly refer to a downlink time unit including an uplink sub-band, or a variable time unit including an uplink sub-band (i.e., a time unit in which a transmission direction is variable).

In the embodiment of the present disclosure, the time unit may be in a slot, symbol, or duration (span), which is not limited by the present disclosure. Wherein a span comprises a plurality of consecutive symbols.

In the embodiment of the disclosure, the resource set occupied by the PDCCH and the first resource set occupied by the uplink sub-band do not overlap.

In step 202, a PDCCH transmitted by a base station is detected and received on a resource included in the resource set.

In the above embodiment, the terminal detects and receives the PDCCH on the resources included in the resource set, and since the determined resource set does not overlap with the first resource set occupied by the uplink subband, it is possible to avoid reducing the transmission performance of the PDCCH, and improve the reliability of full duplex communication.

In some alternative embodiments, referring to fig. 3, fig. 3 is a flowchart illustrating a channel transmission method according to an embodiment, which may be performed by a terminal, the method may include the steps of:

in step 301 overlapping resources belonging to both the CORESET and the first set of resources are determined.

In the embodiment of the present disclosure, the overlapping resource is a resource of an overlapping portion of CORESET and the first resource set.

In step 302, a second set of resources and a set of remaining resources are determined.

In an embodiment of the present disclosure, the second resource set includes at least the overlapping resources described above, and CORESET includes the second resource set and the remaining resource set.

In one possible implementation, when determining the second set of resources, a preset number set may be provided by the protocol, where the preset number in the preset number set may be a positive integer multiple of 6, considering that when the base station indicates RBs occupied by CORESET through a bit map with a length of 45 bits (bits), the preset number set is in granularity of 6 RBs. For example, the preset number set includes {6, 12, 18 … … }.

Wherein if the total number of RBs occupied by the second resource is equal to the first preset number included in the preset number set, it may be determined that only the overlapping resources are included in the second resource set. The first preset number may be any one preset number in the preset number set.

Or if the total number of the Resource Blocks (RBs) occupied by the second resource is not equal to any preset number in a preset number set, the terminal may determine the second preset number of RBs including the overlapping resource in the second resource set. Wherein the second preset number may be a smallest one of the preset number sets that is greater than the total number of RBs.

For example, if the total number of RBs occupied by the overlapping resources is 3, the second preset number is 6, and the terminal determines that the second resource set includes a total of 6 RBs including 3 RBs occupied by the overlapping resources.

For another example, the total number of RBs occupied by overlapping resources is 8, and the second preset number is 12. The terminal determines a total of 12 RBs of the second set of resources including 8 RBs occupied by the overlapping resource.

Accordingly, after determining the second resource set, the terminal may obtain the remaining resource set after removing the second resource in CORESET.

In step 303, the remaining set of resources is determined as the set of resources occupied by the PDCCH.

In step 304, the PDCCH sent by the base station is detected and received on the resources included in the set of resources.

In the above embodiment, the terminal may remove at least the overlapping resources overlapping with the first resource set in CORESET, determine the obtained remaining resource set as the resource set occupied by the PDCCH, and detect and receive the PDCCH sent by the base station on the resources included in the resource set. And the transmission performance of the PDCCH is prevented from being reduced, and the reliability of full duplex communication is improved.

In step 402, a second set of resources and a set of remaining resources are determined.

In an embodiment of the present disclosure, the second resource set includes at least the overlapping resources described above, and CORESET includes the second resource set and the remaining resource set. In one possible implementation, the terminal may provide a preset number set by the protocol when determining the second resource set, where the preset number in the preset number set may be a positive integer multiple of 6, considering that when the base station indicates RBs occupied by CORESET through a bit map with a length of 45 bits (bits), the preset number set is in granularity of 6 RBs. For example, the preset number set includes {6, 12, 18 … … }.

If the total number of the resource blocks RB occupied by the second resource is not equal to any one preset number in the preset number set, the terminal may determine the second preset number of RBs including the overlapping resource in the second resource set. Wherein the second preset number may be a smallest one of the preset number sets that is greater than the total number of RBs.

In another possible implementation, CORESET may be determined to be the second set of resources, and accordingly, the terminal may determine that the remaining set of resources is empty.

In step 403, each second resource included in the second resource set is shifted by a first number of RBs in the frequency domain, to obtain a third resource set.

In an embodiment of the present disclosure, the third set of resources does not overlap with the first set of resources.

In one possible implementation, the terminal may determine the first number according to a protocol convention.

In another possible implementation, the terminal determines the first number based on indication information sent by the base station. Wherein the indication information is used to indicate the first number. It should be noted that, if the entire CORESET is determined as the second resource set, the third resource set obtained after offsetting the second resource set by the first number of RBs needs to be located entirely within the activated downlink BWP.

In step 404, a union of the remaining set of resources and the third set of resources is determined as the set of resources.

Wherein if the remaining set of resources is empty, a third set of resources may be determined as the set of resources occupied by the PDCCH.

In step 405, on the resources included in the resource set, a PDCCH sent by the base station is detected and received.

In the above embodiment, the terminal may offset the second resource in CORESET, determine, based on the third resource set obtained after the offset and the union of the remaining resource sets, the resource set occupied by the PDCCH, and detect and receive the PDCCH sent by the base station on the resource included in the resource set.

In the embodiments of the present disclosure, a PDCCH candidate (candidate) refers to one resource location where a PDCCH may be located. The plurality of PDCCH candidates together form a PDCCH candidate set.

The terminal may perform mapping of the PDCCH based on CORESET to determine the PDCCH candidate set.

In step 502, a first PDCCH candidate in the PDCCH candidate set is determined that there is an overlap with the first resource set.

In the embodiment of the present disclosure, the terminal may first determine, in the PDCCH candidate set, a first PDCCH candidate overlapping with the first resource set. The number of first PDCCH candidates may be one or more, which is not limited by the present disclosure.

In step 503, the first PDCCH candidate is removed from the PDCCH candidate set, and the remaining PDCCH candidates are obtained.

In the embodiment of the present disclosure, after the first PDCCH candidate overlapping with the first resource set is removed directly in the PDCCH candidate set, the remaining PDCCH candidate may be obtained.

Or, the base station may send the indication information or the indication message to the terminal in an implicit manner, for example, when the base station sends a certain message to the terminal, the base station determines the message content corresponding to the resource set occupied by the current PDCCH based on the predefined correspondence between different contents of the message and different resource sets, and sends the message content to the terminal, and the terminal may determine the resource set occupied by the PDCCH corresponding to the message content based on the correspondence.

The present disclosure does not limit the specific content or manner of informing the terminal of the resource set occupied by the PDCCH determined by the base station, where the base station sends the indication information or indication message to the terminal.

The above is merely exemplary, and the terminal may determine the set of resources occupied by the PDCCH and report the set of resources to the base station. The base station determines the resource set occupied by the PDCCH based on the information content reported by the terminal, and transmits the PDCCH to the terminal on the corresponding resource, which is not limited in this disclosure.

In order to facilitate an understanding of the above-described aspects, the present disclosure provides the following embodiments.

In embodiment 1, the terminal is a Rel-18 and subsequent terminals, which have half duplex capability or full duplex capability, and the patent is not limited in any way. It is assumed that the base station side performs full duplex operation in the downlink time slot of the time division duplex (Time Division Duplexing, TDD) band, that is, performs scheduling of downlink data and uplink data simultaneously.

In this embodiment, it is assumed that CORESET configured by the base station for the terminal overlaps with the first set of resources occupied by UL subband on the SBFD time unit. SBFD time units are specified in the presently disclosed embodiments as DL time units or flexible time units where UL subbands are present.

As a specific example, assume that CORESET configured by a base station for a terminal occupies 18 RBs in succession in the frequency domain and 3 symbols in the time domain. The frequency domain resource of CORESET is indicated by 45bit bitmap, and the time domain resource is indicated as 3 continuous OFDM symbols by duration indication information. Specifically, it is assumed that RB indexes (index) occupied by the CORESET in the active DL BWP are rb#0 to rb#17, and that RB indexes occupied by the UL subband in the active DL BWP are rb#15 to rb#35, as shown with reference to fig. 12.

It should be noted that this patent is not limited to configuring or indicating the with-the-art reference (reference) RB used by UL subband. The present embodiment only declares the RB positions occupied by UL subband in active BWP. The overlap relationship between CORESET and UL subband is also shown, for example, in fig. 12.

In this embodiment, when there is an overlap between a part of resources of CORESET and UL subband, NR-PDCCH is transmitted by:

the base station transmits NR-PDCCH in the residual resource set obtained after the RBs overlapped with the first resource set are removed.

When the total number of RBs occupied by overlapping resources simultaneously belonging to CORESET and the first resource set in UL subband is smaller than 6, the terminal completely removes 6 RBs including the overlapping resources in CORESET to obtain a residual resource set.

And the terminal determines the rest resource set as the resource set occupied by the PDCCH, and detects and receives the NR-PDCCH on the resources included by the resource set.

Likewise, for the base station, when the total number of RBs occupied by overlapping resources belonging to both CORESET and the first set of resources in UL subband is less than 6, the base station removes all 6 RBs including the overlapping resources in CORESET.

Specifically, when mapping NR-PDCCH in CORESET, the base station needs to remove the RBs overlapping CORESET and UL subband and map NR-PDCCH on the RBs included in the residual resource set.

In this embodiment, since the total number of RBs occupied by overlapping resources is 3, the base station needs to remove a total of 6 RBs including the 3 RBs, that is, the base station performs mapping and transmission of NR-PDCCHs only on RBs #0 to RB # 11. When the SBFD terminal detects that NR-PDCCH is received on the CORESET, the NR-PDCCH is only mapped on RB#0 to RB#11. The terminal detects and receives PDCCHs transmitted by the base station on RB#0 to RB#11.

It should be noted that the method described in this embodiment can be directly applied to the configuration of CORESET that is discontinuous in the frequency domain. The specific method is completely consistent with the continuous scheme of CORESET in the frequency domain, and is not described herein.

In embodiment 2, the terminal is a Rel-18 and subsequent terminals, which have half duplex capability or full duplex capability, and the present patent is not limited in any way. It is assumed that the base station side performs full duplex operation in the downlink timeslot of the TDD band, that is, performs scheduling of downlink data and uplink data simultaneously.

As a specific example, assume that CORESET configured by a base station for a terminal occupies 18 RBs in succession in the frequency domain and 3 symbols in the time domain. The frequency domain resource of CORESET is indicated by 45bit bitmap, and the time domain resource is indicated as 3 continuous OFDM symbols by duration indication information. Specifically, it is assumed that RB indexes (index) occupied by the CORESET in the active DL BWP are rb#0 to rb#17, and that RB index occupied by the UL subband in the active DL BWP is rb#15 to rb#35, as shown with reference to fig. 12.

In this embodiment, when there is an overlap between CORESET and the first set of resources, the NR-PDCCH is transmitted by:

the base station removes the first PDCCH transmitting with the first resource set having overlap, i.e. does not transmit downlink control information on said first PDCCH transmitting (DL control information).

The terminal discards, i.e. does not detect reception DL control information on, the first PDCCH candidate with UL subband.

Specifically, when the first PDCCH candidate in the NR PDCCH candidate set is mapped to the RB overlapping with the first resource set occupied by the UL subband, the base station discards the first PDCCH candidate, i.e., does not map control information thereon. The terminal also does not expect to detect the received PDCCH candidate on the RB overlapping with UL subband.

Further, if any one RB is included in the first PDCCH candidate map RB and overlaps with UL subband, the base station and the terminal discard the first PDCCH candidate.

In embodiment 3, the terminal is a Rel-18 and subsequent terminals, which have half duplex capability or full duplex capability, and the present patent is not limited in any way. It is assumed that the base station side performs full duplex operation in the downlink timeslot of the TDD band, that is, performs scheduling of downlink data and uplink data simultaneously.

In this embodiment, when there is an overlap in the first resource set occupied by CORESET and UL subband, the NR-PDCCH is transmitted by:

and the base station offsets COESET on the SBFD symbol and ensures that there is no overlap between the offset COERSET and the first resource set.

The first RB number of the offset is configured by the base station or determined by a predefined manner.

The terminal divides CORESET into a second set of resources and a set of remaining resources. And according to a predefined rule or indication information sent by the base station, each second resource in the second resource set is shifted on the SBFD symbol to obtain a third resource set, and the union of the third resource set and the rest resource set is determined as the resource set occupied by the PDCCH.

The terminal detects the received NR-PDCCH on the resources included in the resource set.

The first number of RBs to which the third set of resources is offset may be configured by the base station or determined by a predefined manner.

In this embodiment, since rb#15, rb#16, and rb#17 included in CORESET overlap with the first resource set occupied by UL subband, the corresponding 6 RBs need to be shifted until there is no overlap with the first resource set.

In this embodiment, the RBs #12 to RB #17 included in CORESET are determined as the third resource set, and offset in the frequency domain is performed to be offset to RBs #36 to RB #41. After the offset, the RB actually occupied by CORESET includes: rb#0 to rb#11, and rb#36 to rb#41. The base station maps NR PDCCHs on the RBs #0 to #11 and the RBs #36 to #41, and the terminal detects the received NR PDCCHs on the RBs #0 to #11 and the RBs #36 to #41.

Note that in performing RB offset, offset is required to be performed with 6 RBs as granularity. The offset is performed only within an SBFD time unit (e.g., SBFD slot).

In embodiment 4, the terminal is a Rel-18 and subsequent terminals, which have half duplex capability or full duplex capability, and the present patent is not limited in any way. It is assumed that the base station side performs full duplex operation in the downlink timeslot of the TDD band, that is, performs scheduling of downlink data and uplink data simultaneously.

the terminal determines a new CORESET on other frequency domain resources than the first set of resources.

That is, the bitmap of 45 bits length used to configure CORESET ignores the UL subband bandwidth at the time of mapping.

The base station determines a new CORESET on other frequency domain resources than the first set of resources, i.e. on the actual downstream BWP

Specifically, the terminal determines, according to CORESET indication information sent by the base station, a specific frequency domain resource location occupied by a new CORESET on a resource that does not overlap with the first resource set, for example, as shown in fig. 13.

The base station transmits CORESET indication information, determining the resources that CORESET occupies in the actual (virtual) DL BWP. Specifically, it is assumed that active DL BWP includes 100 RBs, and UL subband is configured in one DL slot. The RBs occupied by the UL sub are RB#15 to RB#35. Then in this embodiment virtual DL BWP contains actual RB index of { rb#0 to rb#14, rb#36 to rb#99}.

Assuming that the CORESET configured by the base station for the terminal includes 18 continuous RBs, taking a bitmap as an example, the 45-bit long bitmap is:

{111000000000000000000000000000000000000000000000}。

referring to fig. 14, the base station and the terminal detect the received NR PDCCH therein according to CORESET in virtual BWP on SBFD slot.

In the embodiment, the transmission performance of the PDCCH can be prevented from being reduced, and the reliability of full duplex communication is improved.
