Description

Information sending and receiving method and device Technical Field

[0001] The present application relates to the field of communications. Background Art

[0002] The current 3GPP protocol has introduced the Multiple Transmit / Receive Point (multi-TRP) feature for enhanced massive MIMO. With multi-TRP, a serving cell can schedule a user equipment (UE) across two TRPs, providing better coverage and reliability, and potentially higher data rates for physical channels such as the PDSCH, PUSCH, PDCCH, and PUCCH.

[0003] For the multi-TRP scenario, there are single-DCI mode and multi-DCI mode. In single-DCI mode, the same downlink control information (DCI) is used to schedule the UE's transmission in two TRPs; in multi-DCI mode, the UE is scheduled separately by independent DCI from different TRPs.

[0004] It should be noted that the above introduction to the technical background is merely for convenience, to provide a clear and complete description of the technical solutions of this application and to facilitate understanding by those skilled in the art. It should not be assumed that the above technical solutions are well known to those skilled in the art simply because they are described in the background technology section of this application.

[0005] Summary of the Invention

[0006] In the discussion of uplink and downlink MIMO evolution technology in Release 18, it was agreed that in multi-DCI multi-TRP operations, two timing advances (TAs) would be supported. Two timing advance groups (TAGs) would be configured in the same serving cell, and each TAG would have a corresponding time alignment timer (TAT). In other words, different TRP transmissions in the same serving cell can have different timing advance attributes and belong to different TAGs.

[0007] In the current 3GPP specifications, each serving cell supports only one TAG. Therefore, when the TAT associated with this TAG expires, the UE needs to notify the RRC to release all PUCCH and Sounding Reference Signal (SRS) configured in the serving cell associated with this TAG, clear downlink allocated resources and configured uplink grants (UL Grants), and clear any PUSCH resources used for semi-persistent CSI reporting. The configuration of these resources is based on the BWP configuration.

[0008] The inventors discovered that since Release 18 agrees that the service cell supports two TAs in the case of multi-DCI and multi-TRP, that is, one service cell can be configured with two TAGs, each corresponding to a different TAT. Therefore, in the same service cell, there is a situation where one TAT times out while the other TAT is still running. The TAG associated with the TAT that has not timed out still has a reliable TA. Therefore, the service cell and the UE can continue to communicate and transmit data using the TRP corresponding to the TAG, and related services should not be affected. However, for the TAG with a TAT timeout, related services will be affected, such as releasing and clearing related configured resources, or caching these resources for service recovery after re-acquisition of synchronization. In either case, the UE needs to be able to distinguish which TAG the related resources belong to, and then maintain the resources based on the TAG, such as use, cache, release, clear, etc. Since the resources that need to be maintained are currently configured according to the BWP, it is difficult to identify and distinguish them according to the TAG.

[0009] Supporting the configuration of two TAGs within a serving cell is a new enhancement introduced in Release 18 for multi-DCI and multi-TRP. Currently, resources such as PUCCH / SRS / UL Grant / DL Assignment / PUSCH for semi-persistent CSI report are all configured based on BWP and have no association information with TAG.

[0010] According to the discussion and decision of Release 18, the association between TRP and TAG will not be restricted or bound. Instead, the RRC message will be used to specify which TAG each UL / Joint TCI-state is associated with, or to associate the TAG ID with the UL / Joint TCI-state.

[0011] According to RAN1's ​​decision, a new parameter applyIndicatedTCIStateXX for mTRP-UTCI (multi-TRP Unified TCI) is introduced in the configuration of related resources to inform the UE of the TCI state applied to the configured resources: {the first, the second, both, none}. The relevant resources are as follows:

[0012] -BWP-DownlinkDedicated

[0013] -ConfiguredGrantConfig

[0014] -ControlResourceSet

[0015] -CSI-AperiodicTriggerStateList

[0016] -PUCCH-Config

[0017] -SRS-Config

[0018] However, the above decision of RAN1 does not indicate the association between TCI state and TAG.

[0019] Another problem in the prior art is that currently, each serving cell only supports one TAG ID configuration, and there is no description of how to indicate the situation in which a cell supports multiple TAGs in Release 18.

[0020] Therefore, at present, when a serving cell is configured with two TAGs, the identifier of the second TAG is not configured to specify; and, when the TAT associated with one TAG times out while the TAT associated with the other TAG is still running, the UE cannot capture which resources will be affected, that is, which resources are related to the TAG with timed out TAT, and therefore cannot release or cache the resources with unreliable TA status separately while keeping the resources with normal TA status to continue business; these resources are either all retained, resulting in resource waste; or all cleared or released, resulting in business impact on the resources corresponding to the normal part of the TA.

[0021] In order to solve one or more of the above problems, embodiments of the present application provide a method and apparatus for sending and receiving information.

[0066] Figure 2 is a schematic diagram of a multi-TRP scenario according to an embodiment of the present application. As shown in Figure 2, a serving cell can schedule terminal device 102 via two TRPs, TRP1 and TRP2. In addition, in multi-DCI mode, terminal device 102 is scheduled by independent DCIs from different TRPs.

[0067] In addition, as shown in Figure 2, two tags, TAG1 and TAG2, are configured in the same service cell, and each TAG is configured with a corresponding TAT. In other words, different TRP transmissions in the same service cell can have different time advance attributes and belong to different tags, that is, the transmission of TRP1 belongs to TAG1, and the transmission of TRP2 belongs to TAG2.

[0068] The following describes various implementations of the present application in conjunction with the accompanying drawings. These implementations are merely illustrative and are not intended to limit the present application.

[0069] Embodiments of the first aspect

[0070] An embodiment of the present application provides a method for sending and receiving information, which is applied to a terminal device, such as the terminal device 102 in Figures 1 and 2.

[0071] FIG3 is a schematic diagram of a method for sending and receiving information according to an embodiment of the present application. As shown in FIG3 , the method includes:

[0072] 301: The terminal device receives a first configuration from the network device;

[0073] The first configuration is at least used to indicate that a first timing advance group (TAG) is associated with a first resource; the first TAG includes a first serving cell of the terminal device; and the first resource is a resource of the first serving cell of the terminal device.

[0074] In some embodiments, two TAGs are configured in the same serving cell, namely a first TAG and a second TAG, such as TAG1 and TAG2 in Figure 2. For example, the first TAG includes the first serving cell of the terminal device.

[0075] In some embodiments, the first configuration is at least used to indicate that the first TAG is associated with the first resource, and the first resource is a resource of the first serving cell of the terminal device, that is, a resource configured for the first serving cell of the terminal device. In addition, the first serving cell refers to a serving cell of the terminal device.

[0076] For example, the first resource includes at least one of the following: physical uplink control channel (PUCCH); sounding reference signal (SRS); downlink assignment; uplink grant; physical uplink control channel for semi-persistent CSI reporting (PUSCH for semi-persistent CSI reporting).

[0077] In this way, when the TAT related to the first TAG times out and the TAT related to the second TAG is still running, the terminal device can cache, suspend or release the resources related to the first TAG whose TAT has timed out without affecting the communication transmission on the resources related to the second TAG whose TAT is still running.

[0078] In some embodiments, the first TCI state is associated with the first resource, and the association between the first TAG and the first resource means that the first TCI state associated with the first resource is associated with the first TAG;

[0079] For example, the first TCI state associated with the first resource includes at least one of the following: a first TCI state that can be used for the first resource; a first TCI state that is applied to the first resource; and a first TCI state that is used to send or receive signals on the first resource.

[0080] In some embodiments, the configuration information of the first TCI state includes an identifier of the first TAG, and the first TCI state is associated with the first TAG. Thus, the first TAG is associated with the first resource.

[0081] For example, the identifier of the first TAG is the ID (identity) of the first TAG.

[0082] In some embodiments, the configuration of the identifier of the first TAG is a configuration related to the number of TAGs included in the configuration information of the first serving cell or an optional configuration.

[0083] In some embodiments, the TCI state includes an uplink TCI state and / or a downlink TCI state. For example, the TCI state is indicated by TCI-State.

[0084] For example, a field indicating the TAG ID is added to the TCI-State domain, and the tag-Id field is optionally configured. That is, the tag-Id field is optional. When the serving cell is configured with two tags, the tag-Id field is used to indicate the tag ID associated with this TCI-State. In addition, when the serving cell is configured with more than one tag, this field is used to indicate the tag associated with this TCI-State; when the serving cell is configured with only one tag, this field does not need to be configured.

[0085] An example of TCI-State is as follows:

[0086] For another example, a field for indicating the TAG ID is added to the TCI-UL-State-r17 field, and tag-Id is optionally configured, that is, the tag-Id field is optional (OPTIONAL).

[0087] When the serving cell is configured with two TAGs, the tag-Id field is used to indicate the TAG ID associated with this TCI-State. In addition, when the serving cell is configured with more than one TAG, this field is used to indicate the TAG associated with this TCI-State. When the serving cell is configured with only one TAG, this field can be omitted.

[0088] An example of TCI-UL-State-r17 is as follows:

[0089] For example, for the tag-Id field, its definition can be: Timing Advance Group ID, as specified in TS 38.321[3], indicates the TAG ID which this TCI-State associates to. This field is optional when this cell belongs to only one TAGs.

[0090] In some embodiments, the configuration information of the first TCI state includes an index of the first TAG in the configuration information of the first serving cell, and the first TCI state is associated with the first TAG.

[0091] In some embodiments, the configuration of the index of the first TAG is a configuration related to the number of TAGs included in the configuration information of the first serving cell or an optional configuration.

[0092] For example, a TAG indicating application is added to the TCI-State field, and the applyIndicatedTAG field is optionally configured, that is, the applyIndicatedTAG field is optional.

[0093] When the serving cell is configured with two TAGs, this field is used to indicate whether the TCI-State is associated with the first or second TAG of the serving cell. When the serving cell is configured with only one TAG, this field does not need to be configured.

[0094] An example of TCI-State is as follows:

[0095] For another example, a TAG indicating application is added in the TCI-UL-State-r17 field, and the applyIndicatedTAG field is optionally configured, that is, the applyIndicatedTAG field is optional (OPTIONAL).

[0096] When the serving cell is configured with two TAGs, this field is used to indicate whether the TCI-State is associated with the first or second TAG of the serving cell. When the serving cell is configured with only one TAG, this field does not need to be configured.

[0097] An example of TCI-UL-State-r17 is as follows:

[0098] For example, for the field applyIndicatedTAG, its definition can be: This field indicates which TAG of the serving cell to be applied for this TCI State, as specified in TS 38.321[3], This field can be optional present when this cell belongs only one TAGs.

[0099] In some embodiments, the first TCI state associated with the first resource is a first TCI state applied to the first resource; the first TCI state applied to the first resource is indicated by a parameter related to applyIndicatedTCI-State included in the configuration information of the first resource. For example, the parameter related to applyIndicatedTCI-State is a parameter such as "applyIndicatedTCI-State-r18" or "applyIndicatedTCI-StateDCI-1-0-r18."

[0100] In some embodiments, the indication of the applyIndicatedTCI-State-related parameter includes information about the first TAG, and the first TCI state applied to the first resource is associated with the first TAG. For example, the information about the first TAG includes index information of the first TAG in the configuration information of the first serving cell.

[0101] For example, for parameters related to applyIndicatedTCI-State, the part of the definition used to indicate the first TAG information may be: This field indicates,for PUCCH / PUSCH transmission(s)or PDCCH / PDSCH reception or CSI-RS resource(set)or SRS resource set,if UE applies the first,the second(or both or none of the)"indicated"UL / DL only TCI or joint TCI.The first indicated UL / DL only TCI or joint TCI is associated with the first TAG ID specified in the serving cell; And the second indicated UL / DL only TCI or joint TCI is associated with the second TAG ID specified in the serving cell.

[0102] That is, the first UL / DL only TCI or joint TCI is associated with the first TAG configured in the serving cell, and the second UL / DL only TCI or joint TCI is associated with the second TAG configured in the serving cell.

[0103] The terminal device establishes an association between the TAG ID and the configuration resources of the service cell according to the TAG sequence configured in the service cell, and can then maintain the configuration resources of the service cell according to the TAG.

[0104] In some embodiments, as shown in FIG3 , the method further includes:

[0105] 302: The terminal device maintains the first resource according to the first configuration and the first TAG, and the first TAG is associated with the first resource.

[0106] For example, the terminal device caches, suspends, or releases the first resource according to the first TAG, wherein a first time alignment timer (TAT) times out;

[0107] For another example, the terminal device recovers the first resource according to the first TAG, wherein the first TAT recovers from a timeout state to a running state; the first TAT is associated with the first TAG.

[0108] In some embodiments, as shown in FIG3 , the method further includes:

[0109] 303: The terminal device receives a second configuration from the network device, where the second configuration is used to configure a first serving cell of the terminal device, and the second configuration includes information about a TAG to which the first serving cell belongs. Operation 303 is optional.

[0110] In this way, by enhancing the configuration of the TAG in the configuration of the serving cell, it is possible to support the configuration of two different TAGs in the same serving cell.

[0111] The existing configuration for configuring the serving cell of the terminal device includes a field tag-Id, which is defined as: Timing Advance Group ID, as specified in TS 38.321[3], which this cell belongs to.

[0112] In some embodiments, the configuration of the TAG information to which the first service cell belongs is multiple TAG identifiers and / or TAG extension identifiers, and the other TAG identifiers except the first TAG identifier among the multiple TAG identifiers are mandatory configurations or optional configurations; the extension identifier is a mandatory configuration or an optional configuration.

[0113] For example, an optional configuration field tag-Id, such as tag-Id2 or tag-Id-Ext, is added to the configuration of the first service cell (second configuration) of the terminal device, that is, the field tag-Id2 or tag-Id-Ext is optional (OPTIONAL).

[0114] When the serving cell is configured with two TAGs, this field is used to indicate the ID of the second TAG. In addition, when the serving cell is configured with only one TAG, this field does not need to be configured.

[0115] An example of a portion of the second configuration is as follows:

[0116] Another example of a portion of the second configuration is as follows:

[0117] For example, for the field tag-Id2 or tag-Id-Ext, its definition can be: Timing Advance Group ID, as specified in TS 38.321[3], this field present when this cell belongs to more than one TAGs, indicates the second TAG ID which this cell belongs to.

[0118] In some embodiments, the configuration of the information of the TAG to which the first serving cell belongs is a SEQUENCE type TAG identifier or a TAG identifier list.

[0119] In some embodiments, the configuration of the information of the TAG to which the first serving cell belongs is a TAG identifier and a mandatory or optional SEQUENCE type TAG extension identifier or a TAG identifier list or a TAG identifier extension list.

[0120] In some embodiments, the SEQUENCE type TAG extension identifier or TAG identifier list or TAG identifier extension list includes identifiers of other TAGs other than the first TAG to which the first service cell belongs, and includes or does not include the identifier of the first TAG to which the first service cell belongs.

[0121] In one embodiment, the tag-Id configuration in the existing configuration is extended to a SEQUENCE type field tag-Id or tag-Id-List. When the serving cell is configured with more than one TAG, the SEQUENCE contains more than one TAG-Id, which is used to indicate the TAG identities configured in the serving cell.

[0122] Another example of part of the second configuration is as follows:

[0270] In some embodiments, for the case where two TAGs, i.e., two PTAGs, are configured in SpCell, if a SCell is configured with only one TAG, and it is the same as one of the PTAGs in SpCell, this situation is not covered in the current specification discussion, so it is necessary to supplement this situation.

[0272] The first SpCell is a SpCell of the terminal device, the first SCell is an SCell of the terminal device, and the first cell group is a cell group of the terminal device.

[0273] FIG14 is a schematic diagram of a method for processing a time alignment timer timeout according to an embodiment of the present application. As shown in FIG14 , the method includes:

[0274] 1401: a first time alignment timer (TAT) associated with a first PTAG of the at least two PTAGs is running, and a second TAT associated with the second PTAG times out;

[0275] 1402: The terminal device applies one or more of the following processes to the first SCell: flush all HARQ buffers; notify RRC to release PUCCH; notify RRC to release SRS; clear any configured downlink allocation and configured uplink grant; clear any PUSCH resources used for semi-persistent CSI reporting; maintain N of the TAG TA .

[0276] A specific example is as follows:

[0277] 1>when a timeAlignmentTimer expires:

[0278] 2>if the timeAlignmentTimer is associated with a PTAG,then for all Serving Cells configured with this TAG and only one TAG configured while a second PTAG of the associated SpCell for which the timeAlignmentTimer is running:

[0279] 3>flush all HARQ buffers;

[0280] 3>notify RRC to release PUCCH, if configured;

[0281] 3>notify RRC to release SRS, if configured;

[0282] 3>clear any configured downlink assignments and configured uplink grants;

[0283] 3> Clear any PUSCH resource for semi-persistent CSI reporting;

[0284] 3> Maintain N TA (defined in TS 38.211[8]) of this TAG.

[0285] Another specific example is as follows:

[0286] 1> When a timeAlignmentTimer expires:

[0287] 2> If the timeAlignmentTimer is associated with a PTAG while TAT for the other PTAG of SpCell is running, then for all SCell belonging to this TAG and configured with only TAG:

[0288] 3> Flush all HARQ buffers;

[0292] 3> Clear any PUSCH resource for semi-persistent CSI reporting;

[0293] 3> Maintain N TA (defined in TS 38.211[8]) of this TAG.

[0294] It can be seen from the above embodiments that in the case where two TAGs, i.e., two PTAGs, are configured in SpCell, if a certain SCell is configured with only one TAG, and it is the same as one of the PTAGs in SpCell, by describing the processing procedure when one TAT times out and the other TAT is running, the terminal device can perform appropriate processing in this situation.
