Description

Indication method and terminal for Transmission Configuration Indication (TCI) state

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an indication method and a terminal for indicating a TCI status by transmission configuration.

Background

In a mobile communication system, a Radio Resource Control (RRC) may configure a Physical Downlink Shared Channel (PDSCH) Configuration (PDSCH-config) in a downlink (downlink) Bandwidth Part (BWP), and configure a list (list) of a corresponding Transmission Configuration Indicator (TCI) state (TCI-state) in the PDSCH-config, such as TCI-statetoaddmodlist.

Among other parameters, the RRC may also configure Control Resource Set (CORESET) parameters, including parameters such as CORESET #0 and parameters of other CORESETs besides CORESET # 0. The list of TCI states, such as TCI-statesdcch-ToAddList, is configured in the RRC configuration of other CORESET. Wherein the list is a subset of the PDSCH-cnfig configured TCI status list, i.e., TCI-statesdcch-ToAddList is a subset of TCI-statetoaddmodlist.

The Media Access Control (MAC) Control unit (Control Element, CE) includes TCI status Indication information (MAC CE TCI State Indication) and CORESET Identification (ID) Indication, and the TCI status identification (TCI State ID) in the Indication indicates the TCI status of the CORESET ID. Wherein, the TCI state identifies TCI-StatesPDCCH-ToAddList and/or TCI-StatesPDCCH-ToReleaseList applied to CORESET configuration. However, in the configuration of CORESET #0, TCI-statesdcch-ToAddList is not configured, and the MAC CE cannot indicate the TCI state of CORESET #0 according to the configuration information of CORESET, which affects the effectiveness and efficiency of communication.

The target TCI state may be determined when the TCI state identifier is applied to a first TCI state list of the target PDSCH configuration information, or may be determined when the TCI state identifier is applied to a second TCI state list of the preset CORESET configuration information. The preset CORESET may be a specific CORESET or may not be the specific CORESET.

Suppose the terminal receives the MAC CE at active BWP; and acquiring a CORESET identifier and a TCI state identifier (TCI-StateId) carried in the MAC CE. If the CORESET identifier is configured to be #0, before the MAC CE takes effect, the RRC reconfigures the TCI state list in the PDSCH configuration information of active BWP, the terminal applies the TCI state identifier indicated by the MAC CE to the TCI state list in the PDSCH configuration information of BWP associated with the preset CORESET, and activates the TCI state corresponding to TCI-State id to be the TCI state of CORESET # 0.

Or, assuming that if the CORESET identifier is configured as # n, when the TCI state list is not configured in the CORESET # n configuration information configured by the RRC, and before the MAC CE becomes effective, the TCI state list in the PDSCH configuration information of the RRC reconfiguration active BWP is applied to the TCI state list in the PDSCH configuration information of the BWP associated with the preset CORESET, and the TCI state corresponding to the TCI-state id is activated as the TCI state of the CORESET # n.

Further, in this scenario, the terminal does not expect to receive a TCI state in which the MAC CE activates not configured in active BWP, at which point the terminal may discard the MAC CE. Suppose the terminal receives the MAC CE at active BWP; and acquiring a CORESET identifier and a TCI state identifier carried in the MAC CE. If the CORESET flag is configured as #0, before the MAC CE becomes effective, the RRC reconfigures the TCI state list in the PDSCH configuration information of the active bwp, and the terminal may discard the MAC CE.

Scene two,

When the preset PDSCH configuration information is the PDSCH configuration information for activating BWP, that is, the terminal determines the TCI state of CORESET in the TCI state list of the PDSCH configuration information for activating BWP in advance (e.g., in agreement). In this scenario, when the terminal performs BWP handover before the MAC CE becomes effective, the target PDSCH configuration information is one of the following:

1. PDSCH configuration information of the initial bandwidth part BWP;

2. PDSCH configuration information of active BWP before handover; suppose the terminal receives the MAC CE at active BWP; and acquiring a CORESET identifier and a TCI state identifier (TCI-StateId) carried in the MAC CE. If the CORESET identifier is configured as #0, BWP handover occurs before the MAC CE becomes effective, the terminal applies the TCI state identifier indicated by the MAC CE to the TCI state list in the PDSCH configuration information of activeBWP before BWP handover, and activates the TCI state corresponding to the TCI-StateId to be the TCI state of CORESET # 0. Or, if the CORESET identifier is configured as # n, when the TCI state list is not configured in the CORESET # n configuration information configured by the RRC and BWP handover occurs before the MAC CE becomes effective, applying the TCI state identifier indicated by the MAC CE to the TCI state list in the PDSCH configuration information of active BWP before BWP handover, and activating the TCI state corresponding to the TCI-state id as the TCI state of CORESET # n.

3. PDSCH configuration information of activated BWP after handover; suppose the terminal receives the MAC CE at active BWP; and acquiring a CORESET identifier and a TCI state identifier (TCI-StateId) carried in the MAC CE. If the CORESET identifier is configured as #0, BWP handover occurs before the MAC CE becomes effective, the terminal applies the TCI state identifier indicated by the MAC CE to the TCI state list in the PDSCH configuration information of active BWP after BWP handover, and activates the TCI state corresponding to the TCI-state id to be the TCI state of CORESET # 0. Or, if the CORESET identifier is configured as # n, when the TCI state list is not configured in the CORESET # n configuration information configured by the RRC and BWP handover occurs before the MAC CE becomes effective, applying the TCI state identifier indicated by the MAC CE to the TCI state list in the PDSCH configuration information of active BWP after BWP handover, and activating the TCI state corresponding to the TCI-state id as the TCI state of CORESET # n.

4. PDSCH configuration information of a first BWP, wherein the first BWP is one of BWPs including CORESET, or the first BWP is predefined;

5. PDSCH configuration information of one of the BWPs associated with the CORESET;

6. PDSCH configuration information of BWP associated with a preset CORESET.

The determination of the target PDSCH configuration information in this scenario is similar to the determination in scenario one, and the specific determination may be implemented by referring to the example introduced in scenario one, which is not described herein again. It is noted that, similar to the scenario one, the terminal does not expect to receive the TCI state whose MAC CE activates the TCI state identifier not configured in the active BWP in the scenario two, and the terminal may discard the MAC CE. Suppose the terminal receives the MAC CE at active BWP; and acquiring a CORESET identifier and a TCI state identifier carried in the MAC CE. If the CORESET flag is configured as #0, BWP handover occurs before the MAC CE becomes effective, and the terminal may discard the MAC CE.

Further, in some special scenarios, the terminal may perform certain predetermined actions upon receiving the MAC CE.

For example, in the case where the active BWP is reconfigured or released before the MAC CE takes effect, the target TCI state is: a quasi-co-location type D of a Synchronization Signal Block (Synchronization Signal and PBCH Block, SSB) during initial access, or a TCI state of a preset CORESET. That is, the SSB of the terminal using the initial access procedure is a quasi Co-location (QCL) type D of a De-Modulation Reference Signal (DMRS) port of the CORESET # 0. Alternatively, the TCI state using CORESET #0 is predefined, and if the TCI state is not configured in CORESET # n, the TCI state of CORESET #0 is considered to be the TCI state of CORESET # n.

For another example, the TCI status flag indicated by the MAC CE received by the terminal is not within the preset flag range. After step 21, further comprising: in case the TCI status flag indicated by the MAC CE is not within the TCI status range configured for the terminal, the terminal performs one of the following actions:

discarding the MAC CE; the terminal does not expect to receive a MAC CE that activates a TCI state that is not in the TCI state list, in which case the terminal may discard the MAC CE.

The MAC CE is applied to activate the target TCI state.

Wherein the target TCI state is indicated when the predefined TCI state identification applies to the first TCI state list,

alternatively, the target TCI state is indicated when the predefined TCI state identification applies to the second TCI state list. The predefined TCI status identifier may be pre-agreed (e.g., agreed by a protocol) or configured by the network device, for example, a certain TCI status identifier is configured as a default TCI status identifier. The first TCI status list may be a TCI status list in the target PDSCH configuration information, and for a specific application example, reference may be made to the above example, which is not described herein again for example.

Alternatively, the target TCI status is indicated when the TCI status flag indicated by the MAC CE received last time is applied to the first TCI status list, or the target TCI status is indicated when the TCI status flag indicated by the MAC CE received last time is applied to the second TCI status list. The first TCI status list may be a TCI status list in the target PDSCH configuration information, and for a specific application example, reference may be made to the above example, which is not described herein again for example.

Also for example, in the case that a specific CORESET is not included in the active BWP, in this case, the terminal may activate the TCI state of the CORESET in the first TCI state list of the target PDSCH configuration information, or activate the TCI state of the CORESET in the second TCI state list of the preset CORESET configuration information.

For example, the terminal receives the MAC CE at active BWP; and acquiring a CORESET identifier and a TCI state identifier (TCI-StateId) carried in the MAC CE. If the CORESET ID is configured as #0, the initial BWP, the BWP ID with the maximum BWP, or the BWP ID with the minimum BWP associated with CORESET #0 are different from the SCS or CP of the active BWP, or the active BWP does not completely contain the bandwidth of CORESET # 0. At this time, the terminal applies the TCI state identifier indicated by the MAC CE to the PDSCH configuration information TCI state list of the initial BWP or the default BWP or the BWP associated with the core set #0 identifying the largest/smallest BWP, and activates the TCI state corresponding to the TCI-state id to be the TCI state of the core set # 0.

Or, the terminal does not expect to receive the TCI state activating the CORESET not in the active BWP in this case, after step 21, further includes: in case the active BWP does not contain a CORESET (the specific CORESET indicated by the CORESET identification in the MAC CE), the MAC CE is discarded. Where the active BWP does not contain CORESET, the cases include, but are not limited to: the BWP activation differs from the BWP specific CORESET associated subcarrier spacing (SCS), Cyclic Prefix (CP), etc. Alternatively, the active BWP does not fully encompass the bandwidth of a particular CORESET. In this case, the terminal also does not expect to receive a TCI state that activates core set not within active BWP, in which case the terminal may discard the MAC CE.

For another example, in the case of BWP handover, step 21 may further include: in case of BWP handover, the terminal performs one of the following actions:

discarding the MAC CE;

a step of executing the application of the MAC CE to activate the target TCI state of the CORESET after a first time after the BWP handover is completed; i.e. the MAC CE activation signaling takes effect from a period of time (e.g. 3ms) after the completion of the BWP handover.

And if the MAC CE or the feedback information of the MAC CE is received at the second time before the BWP switching, executing a step of applying the MAC CE to activate the target TCI state of CORESET. I.e. the MAC CE activation signaling is to be received at least x (e.g. 3) ms before BWP handover, or the feedback information of the MAC CE is to be received at least x ms before BWP handover.

In the method for indicating the TCI state of the transmission configuration indication according to the embodiment of the present invention, when the TCI state of the CORESET needs to be activated, the terminal applies the TCI state identifier indicated by the MAC CE to the first TCI state list in the target PDSCH configuration information or the second TCI state list in the preset CORESET configuration information to indicate the target TCI state of the CORESET, and activates the target TCI state to determine the receiving beam of the related information, thereby ensuring information transmission and improving communication efficiency.
