Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to an information determination method, apparatus and terminal. Background Technology

[0002] Current technology introduces a new Transmission Configuration Indication (TCI) structure that uses the same beam for multiple channels, referred to as a common beam. The network uses the Media Access Control Element (MAC CE) or Downlink Control Information (DCI) to indicate that the beam can be used for transmission on multiple channels.

[0003] The control resource set CORESET (i.e., CORESET#0) with ID 0 is configured by the Physical Broadcast Channel (PBCH) (via the Master Information Block (MIB)) and is used by the terminal to receive System Information (SI). For the broadcast Physical Downlink Control Channel (PDCCH), the terminal determines which common search space corresponding to the Synchronization Signal and PBCH block (SSB) to receive. For the unicast Physical Downlink Shared Channel (PDSCH), it can be scheduled by the DCI associated with CORESET#0.

[0004] In carrier aggregation (CA) scenarios, for a set of component carriers (CCs) or bandwidth parts (BWPs), the network can indicate a common TCI state ID. This common TCI state ID is used to determine at least the common quasi-co-address information of the terminal-specific PDCCH or PDSCH, and / or, to determine at least the common uplink transmit spatial filter information of the terminal-specific PUCCH or PUSCH. The source reference signal (RS) in the common TCI state ID indicated by the target CC can be configured on the target CC or other CCs. The source reference signal in the common TCI state ID has the following characteristics:

[0005] (A) A source RS in a public TCI state ID is cross-CC, meaning it is used for all target CCs;

[0006] (B) The source RS in the public TCI state ID is based on each CC, and the source RS dedicated to each CC is further associated with the same quasi-co-located QCL-TypeD RS.

[0007] Since CORESET#0 is a non-UE-specific or non-UE-dedicated CORESET, it is not yet determined whether the TCI state is used for CORESET#0 in the current technology.

[0008] Therefore, the existing technology has the following problems:

[0009] When the common beam is not used for CORESET#0, it is unclear how to determine the beam information of the DCI-scheduled channel or reference signal on CORESET#0.

[0010] In the CA scenario, if the source RS in the aforementioned public TCI state ID is applied, it is unclear how to determine the relevant information of CORESET#0 on a certain CC. Summary of the Invention

[0011] This application provides an information determination method, apparatus, and terminal that can solve the problems in the prior art of how to determine the beam information of the PDSCH scheduled by DCI on CORESET#0 or how to determine the relevant information of CORESET#0 on a certain CC in a CA scenario.

[0035] The information determination method, apparatus, and terminal provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0036] It should be noted that the beam information mentioned in the embodiments of this application can also be referred to as: beam identification information, spatial relation information, spatial domain transmission filter information, spatial domain reception filter information, spatial filter information, transmission configuration indication state (TCI state) information, quasi-co-addressable (QCL) information, or QCL parameters, etc. Downlink beam information is typically represented using TCI state information or QCL information. Uplink beam information is typically represented using TCI state information or spatial relation information.

[0037] like Figure 2 As shown in the embodiment of this application, an information determination method is provided, including:

[0038] Step 201: The terminal receives a first command, which is used to activate, indicate, or update the common beam information.

[0039] In this step, the common beam information can be determined based on the joint TCI state, separate DL TCI state, or separate UL TCI state in the first command. This common beam information is used to determine the common QCL information for at least the terminal-specific PDCCH or PDSCH, and / or the terminal-specific PUCCH or PUSCH.

[0040] Step 202: The terminal receives a second command, which is used to activate, indicate or update the first beam information, which is the beam information of the control resource set CORESET#0; optionally, the first beam information can also be a common beam information.

[0041] In this step, the second command and the first command can be the same command, that is, the common beam information and the first beam information are indicated by a single command; or the first command and the second command can be different commands, that is, the common beam information and the first beam information are indicated by different commands respectively.

[0042] Optionally, the first beam information may be the same as or different from the common beam information.

[0043] Step 203: The terminal determines the parameter information of the common search space of CORESET#0 on the carrier unit CC or bandwidth portion BWP configured with CORESET#0, or determines the beam information used by the channel or reference signal scheduled by the downlink control information on CORESET#0, based on the common beam information or the first beam information.

[0044] Optionally, the first beam information can also be used for channels associated with CORESET#0, such as the PDCCH on CORESET#0, the PUSCH scheduled by the PDCCH on CORESET#0, the PDSCH scheduled by the PDCCH on CORESET#0, and the channel where the feedback information (such as the HARQ-ACK information) of the channel scheduled by the PDCCH on CORESET#0 is located.

[0045] In at least one optional embodiment of this application, in a carrier aggregation (CA) scenario, the common beam information includes a common transport configuration indicator (TCI) state identifier (such as a common TCI state ID), which is applied to at least one channel or reference signal on a set of CCs or BWPs. The terminal can determine the beam information of a first channel or a first reference signal on a set of CCs or BWPs based on the common TCI state ID.

[0046] Optionally, the first channel may be at least one of terminal-specific PDCCH, terminal-specific PDSCH, terminal-specific PUCCH, and terminal-specific PUSCH.

[0047] Optionally, the public TCI state ID can be the ID of the combined TCI state activated, indicated, or updated by the first command, or the ID of a separate downlink TCI state, or the ID of a separate uplink TCI state, without any specific limitation here.

[0048] Accordingly, in a carrier aggregation (CA) scenario, the first beam information includes a first TCI state identifier (such as a first TCI state ID), which is applied to CORESET#0 on a set of CCs or BWPs. The terminal determines the beam information of CORESET#0 on a set of CCs or BWPs configured by the network based on the first TCI state ID.

[0049] It should be noted that CORESET#0 is configured on at least one specific CC or BWP in the above set of CCs or BWPs; that is, CORESET#0 is not configured on every CC or BWP in a set of CCs or BWPs.

[0050] Optionally, the first TCI state ID can be the same as or different from the public TCI state ID.

[0051] Optionally, the first TCI state ID can be a public TCI state ID or a non-public TCI state ID.

[0052] Optionally, the first TCI state ID can also be used for channels associated with CORESET#0, such as the PDCCH on CORESET#0, the PDSCH scheduled by the PDCCH on CORESET#0, the PUSCH scheduled by the PDCCH on CORESET#0, and the channel where the feedback information (such as HARQ-ACK information) of the channel scheduled by the PDCCH on CORESET#0 is located.

[0053] In at least one optional embodiment of this application, in a CA scenario, step 203 involves the terminal determining parameter information of the common search space of CORESET#0 on the carrier unit CC or bandwidth portion BWP configured with CORESET#0 based on the common beam information or the first beam information, including:

[0054] The terminal determines the reference signal of the quasi-co-address QCL type D of CORESET#0 configured on the CC or BWP based on the common TCI status identifier or the first TCI status identifier.

[0055] The terminal determines the first reference signal based on the determined reference signal of QCL type D;

[0056] The terminal determines the parameter information of the common search space of CORESET#0 on the CC or BWP configured with CORESET#0 based on the first reference signal or the synchronization signal block SSB associated with the first reference signal.

[0057] It should be noted that when the QCL type is QCL type D (QCL-TypeD), the {SpatialRX parameter} corresponding to QCL-TypeD represents beam information.

[0058] As an optional embodiment, the reference signal for the determined QCL type D can be based on each CC or BWP (i.e., the reference signal for the QCL type D determined by the terminal includes: the reference signal for the QCL type D of each CORESET#0 on each CC or BWP configured with CORESET#0). For example, the network is configured with CORESET#0 on CC0, CC1, CC2, and CC3. The QCL-Type D RS of CORESET#0 on CC0 is TRS0 on CC0, the QCL-Type D RS of CORESET#0 on CC1 is TRS1 on CC1, the QCL-Type D RS of CORESET#0 on CC2 is TRS2 on CC2, and the QCL-Type DRS of CORESET#0 on CC3 is TRS3 on CC3.

[0059] As another optional embodiment, the reference signal for the determined QCL type D can also be the common QCL type D reference signal for all CORESET#0s (i.e., the reference signal for the QCL type D determined by the terminal includes: the common QCL type D reference signal for all CORESET#0s on the CC or BWP configured with CORESET#0). For example, if the network configures CORESET#0 on CC0, CC1, CC2, and CC3, the QCL-Type D RS for CORESET#0 on these four CCs is TRS0 on CC0.

[0060] In at least one optional embodiment of this application, the terminal determines, based on the common TCI status identifier or the first TCI status identifier, a reference signal of quasi-co-address QCL type D on the CC or BWP configured with CORESET#0, including:

[0061] If the first TCI status identifier is the same as the common TCI status identifier, the terminal determines the reference signal of the CC configured with CORESET#0 or the QCL type D of CORESET#0 on the BWP based on the common TCI status identifier.

[0062] or,

[0063] If the first TCI status identifier is different from the common TCI status identifier, the terminal determines the reference signal of the CC configured with CORESET#0 or the QCL type D of CORESET#0 on the BWP based on the first TCI status identifier.

[0064] In at least one optional embodiment of this application, the terminal determines a first reference signal based on a determined reference signal of QCL type D, including:

[0065] The reference signal for QCL type D determined by the terminal includes: In the case where each CC or BWP of CORESET#0 has its own reference signal for QCL type D, the same reference signal associated with each reference signal of QCL type D is determined as the first reference signal; optionally, the first reference signal is an SSB. Optionally, the QCL type of the first reference signal is QCL type D.

[0066] For example, the reference signal for QCL type D is determined as follows: in the TCI state determined according to the common TCI state ID or the first TCI state ID, the RS resource ID of type QCL-Type D in the reference signal (or source RS) of the QCL message is determined on each CC / BWP, and is used as the QCL-Type D RS (reference signal of QCL type D) of CORESET#0 on that CC / BWP.

[0067] The QCL-Type D RSs of CORESET#0 on each CC or BWP have a QCL relationship, and these QCL-Type DRSs are associated with the same first reference signal. As an optional embodiment, the common reference signal (i.e., the first reference signal) associated with the reference signals of each QCL type D includes:

[0068] A reference signal of QCL type D is configured in each of the reference signals of CORESET#0 on each CC or BWP of CORESET#0;

[0069] or,

[0070] The reference signal of QCL type D of CORESET#0 is configured on each CC or BWP of CORESET#0.

[0071] In short, in this scenario, the first reference signal can be one of the QCL-TypeD RSs of CORESET#0 on each CC or BWP configured with CORESET#0, or the QCL-TypeD RS of these CORESET#0 QCL-TypeD RSs.

[0072] For example, the network is configured with CORESET#0 on CC0, CC1, CC2, and CC3. The QCL-Type D RS of CORESET#0 on CC0 is TRS0 on CC0, the QCL-Type D RS of CORESET#0 on CC1 is TRS1 on CC1, the QCL-Type D RS of CORESET#0 on CC2 is TRS2 on CC2, and the QCL-Type D RS of CORESET#0 on CC3 is TRS3 on CC3.

[0073] Therefore, TRS0 on CC0 can be a common QCL-Type D RS of TRS1, TRS2, and TRS3, or in other words, TRS1, TRS2, and TRS3 are all associated with TRS0. In this case, TRS0 is the first reference signal. If the QCL-Type DRS of CORESET#0 on CC0 is the SSB on CC0, then this SSB can also be a common QCL-Type D RS of TRS1, TRS2, and TRS3, or in other words, TRS1, TRS2, and TRS3 are all associated with the SSB. In this case, the SSB on CC0 is the first reference signal.

[0074] Alternatively, the common QCL-TypeD RS of CORESET#0 on these four CCs, namely TRS0, TRS1, TRS2, and TRS3, is the SSB on CC0, or in other words, it is associated with the SSB on CC0. This SSB on CC0 is the first reference signal.

[0075] As another optional embodiment, the first reference signal is configured on the first reference CC or the first reference BWP in a set of CCs or BWPs corresponding to the common TCI status identifier;

[0076] or,

[0077] The first reference signal is configured on the second reference CC or the second reference BWP in a set of CCs or BWPs corresponding to the first TCI status identifier;

[0078] or,

[0079] The first reference signal is configured on the third reference CC or the third reference BWP of the CC or BWP configured with CORESET#0; for example, the first reference signal is configured on the CC or the active BWP of the primary cell.

[0080] In at least one optional embodiment of this application, the terminal determines a first reference signal based on a determined reference signal of QCL type D, including:

[0081] When the reference signal for QCL type D determined by the terminal includes: the reference signal for the common QCL type D of all CORESET#0 on the CC or BWP configured with CORESET#0, the reference signal for the common QCL type D is determined to be the first reference signal.

[0082] For example, the reference signal for the determined QCL type D is: the RS resource of type QCL-TypeD in the reference signal (or source RS) of the QCL message in the TCI state determined according to the common TCI state ID or the first TCI state ID. This RS resource is the common QCL-TypeD RS of all CORESET#0.

[0083] For example, if the network is configured with CORESET#0 on CC0, CC1, CC2, and CC3, and the QCL-TypeD RS of CORESET#0 on these four CCs is TRS0 on CC0, then TRS0 is the first reference signal. If the QCL-TypeD RS of CORESET#0 on these four CCs is SSB on CC0, then SSB is the first reference signal.

[0084] As another optional embodiment, the first reference signal (i.e., the reference signal of common QCL type D) is configured on the first reference CC or the first reference BWP in a set of CCs or BWPs corresponding to the common TCI status identifier;

[0085] or,

[0086] The first reference signal (i.e., the reference signal of common QCL type D) is configured on the second reference CC or the second reference BWP in a set of CCs or BWPs corresponding to the first TCI status identifier;

[0087] or,

[0088] The first reference signal (i.e., the reference signal of common QCL type D) is configured on the third reference CC or the third reference BWP of the CC or BWP configured with CORESET#0; for example, the first reference signal is configured on the CC or the active BWP of the primary cell.

[0089] As another optional embodiment, the terminal determines the first reference signal based on the determined reference signal of QCL type D, including:

[0090] If the reference signal for QCL type D determined by the terminal is not an SSB, then the reference signal for QCL type A is determined to be the first reference signal. In other words, the parameter information of the common search space (which may be referred to as searching space #0 or SS#0) of CORESET#0 in this embodiment depends on a reference SSB (which is the first reference signal or an SSB associated with the first reference signal), and the reference SSB is any one of the following:

[0091] If the reference signal of QCL type D in CA CORESET#0 is based on each CC or BWP, then the SSB that is commonly associated with these QCL type D reference signals is taken as the reference SSB.

[0092] If the reference signal of QCL type D of CORESET#0 in CA is the same QCL type D reference signal of all CC or BWP, then this same QCL type D reference signal or its associated SSB shall be used as the reference SSB.

[0093] If the reference signal of QCL type D in CORESET#0 in CA is not an SSB, the reference signal of QCL type A or its associated SSB shall be used as the reference SSB.

[0094] As an optional embodiment, the reference signal of the QCL type D includes at least one of the following:

[0095] Synchronization signal block (SSB);

[0096] Channel State Information Reference Signal (CSI-RS);

[0097] Tracking reference signal TRS;

[0098] Detection reference signal SRS.

[0099] As another optional embodiment, the parameter information of the public search space of CORESET#0 on the CC or BWP includes at least one of the following:

[0100] Listening timing information;

[0101] Time-domain resource information;

[0102] Frequency domain resource information;

[0103] Spatial parameter information;

[0104] QCL information.

[0105] Furthermore, based on the parameter information of the common search space of CORESET#0, the terminal can determine the resource block RB information, time offset information, time slot information, period information, and space reception parameters of CORESET#0 where the common search space is located.

[0106] In at least one optional embodiment of this application, the terminal listens to the common search space of Type0-PDCCH based on the parameter information of the common search space. The terminal determines the listening timing based on the mapping relationship (or association relationship) between SSB and CORESET and / or the search space, and listens to PDCCH at the listening timing.

[0107] In at least one optional embodiment of this application, step 203, in which the terminal determines the beam information used by the channel or reference signal scheduled by the downlink control information on CORESET#0 based on the common beam information or the first beam information, includes:

[0108] When the first beam information is the same as the common beam information, and the time interval between the downlink control information on CORESET#0 and the channel or reference signal scheduled by the downlink control information is less than a preset threshold (or the transmission time of the channel or reference signal is earlier than the application time of the first beam information), the beam information used by the channel or reference signal is determined to include at least one of the following:

[0109] The preceding common beam information indicated by the first command;

[0110] On the active BWP of the cell where the channel or reference signal is located, the terminal listens to the beam information of the CORESET with the smallest ID in the nearest time slot of the CORESET.

[0111] On the active BWP of the cell where the channel or reference signal is located, the beam information of the CORESET with the smallest ID in the CORESET monitored by the terminal.

[0112] Reference CC or reference BWP, the terminal listens for the beam information of the CORESET with the smallest ID in the nearest time slot of the CORESET;

[0113] According to CC or BWP, the beam information of the CORESET with the smallest ID in the CORESET monitored by the terminal;

[0114] The beam information of CORESET#0, where the downlink control information for the channel or reference signal is located;

[0115] On the active BWP of the cell where the channel or reference signal is located, the active beam information corresponding to the minimum code point in the active beam information of the channel or reference signal is applied.

[0116] The activation beam information corresponding to the smallest code point in the activation beam information applied to the channel or reference signal on the reference CC or reference BWP.

[0117] The reference CC or reference BWP includes: a CC or BWP in a set of CCs or BWPs corresponding to the common beam information, or a CC or BWP in a set of CCs or BWPs corresponding to the first beam information, or a CC or BWP configured with CORESET#0.

[0118] For example, in the statements "Activation beam information corresponding to the smallest codepoint in the activation beam information of the channel or reference signal applied to the active BWP of the cell where the channel or reference signal is located;" and "Activation beam information corresponding to the smallest codepoint in the activation beam information of the channel or reference signal applied to the reference CC or reference BWP;", the channel or reference signal is a PDSCH, and the network activates M beam information (TCI state) for the PDSCH on the active BWP of the cell where the PDSCH is located or on the reference CC or reference BWP. These M beam information correspond to codepoints from codepoint 0 to codepoint M-1, respectively. Then, the activation beam information corresponding to codepoint 0 is determined as the beam information used by the PDSCH.

[0119] This embodiment is applicable to both single-carrier and carrier aggregation scenarios. Carrier aggregation scenarios include at least: same-carrier scheduling (e.g., the DCI on CORESET#0 and the PDSCH scheduled by that DCI are located in the same CC) and cross-carrier scheduling (e.g., the DCI on CORESET#0 and the PDSCH scheduled by that DCI are located in different CCs).

[0120] Optionally, "the previous common beam information of the common beam information indicated by the first command" can be referred to as:

[0121] Previous common beam information; or,

[0122] Current public beam information; or,

[0123] The preceding common beam information before the common beam information indicated by the first command; or,

[0124] The previous public TCI state ID; or,

[0125] Current public TCI state ID; or,

[0126] The previous public TCI state ID preceding the public TCI state ID indicated by the first command.

[0127] In at least one optional embodiment of this application, step 203, in which the terminal determines the beam information used by the channel or reference signal scheduled by the downlink control information on CORESET#0 based on the common beam information or the first beam information, includes:

[0128] When the first beam information differs from the common beam information, and the time interval between the downlink control information on CORESET#0 and the channel or reference signal scheduled by the downlink control information is less than a preset threshold (also referred to as the transmission time of the channel or reference signal being earlier than the application time of the first beam information), the beam information used by the channel or reference signal is determined to include at least one of the following:

[0141] For example, in the statements "Activation beam information corresponding to the smallest codepoint in the activation beam information of the channel or reference signal applied to the active BWP of the cell where the channel or reference signal is located;" and "Activation beam information corresponding to the smallest codepoint in the activation beam information of the channel or reference signal applied to the reference CC or reference BWP;", the channel or reference signal is a PDSCH, and the network activates M beam information (TCI state) for the PDSCH on the active BWP of the cell where the PDSCH is located or on the reference CC or reference BWP. These M beam information correspond to codepoints from codepoint 0 to codepoint M-1, respectively. Then, the activation beam information corresponding to codepoint 0 is determined as the beam information used by the PDSCH.

[0142] Optionally, "the previous common beam information of the common beam information indicated by the first command" can be referred to as:

[0143] Previous common beam information; or,

[0144] Current public beam information; or,

[0145] The preceding common beam information before the common beam information indicated by the first command; or,

[0159] Non-terminal dedicated CORESET for terminal monitoring.

[0160] Accordingly, the most recent timeslot that the terminal listens to for CORESET includes: the most recent timeslot that the terminal listens to for terminal-specific CORESET, or the most recent timeslot that the terminal listens to for non-terminal-specific CORESET.

[0161] As another optional embodiment, the CORESET with the smallest ID corresponds to the same CORESET pool index as CORESET#0; it can also be said that the CORESET with the smallest ID and CORESET#0 are configured with the same CORESET pool index.

[0162] As another optional embodiment, the activation beam information applied to the channel or reference signal corresponds to the same CORESET pool index as CORESET#0; it can also be said that the activation beam information applied to the channel or reference signal is configured with the same CORESET pool index as CORESET#0.

[0163] Optionally, the activation beam information corresponding to the minimum codepoint includes: the beam information corresponding to the minimum TCI codepoint among multiple TCI codepoints with different beam information in the activation beam information of the channel or reference signal.

[0164] For example, the network activates M sets of beam information (TCI states) for the PDSCH on the active BWP of the cell where the PDSCH resides, or on the reference CC or reference BWP. These M sets of beam information correspond to codepoints from codepoint 0 to codepoint M-1, where each codepoint among codepoint1, codepoint4, and codepoint5 corresponds to multiple different beam information, and all other codepoints correspond to one beam information. Therefore, the active beam information corresponding to codepoint 1 among codepoint1, codepoint4, and codepoint5, which corresponds to multiple different beam information, can be determined as the beam information used by the PDSCH. This example can be applied to a single DCI mode in a multi-transmitter-receiver (TRP) scenario.

[0174] It should be noted that, for the above-mentioned single-carrier scenario or carrier aggregation scenario, it can also be agreed that when the DCI on CORESET#0 schedules the PDSCH, the time interval between the DCI and the scheduled PDSCH is always greater than or equal to a certain threshold.

[0175] In other words, in the embodiments of this application, when the DCI schedules the PDSCH on CORESET#0, including co-carrier scheduling and cross-carrier scheduling, the terminal determines the beam information of the PDSCH based on the same common beam information of CORESET#0 and the terminal's dedicated CORESET, or based on the first beam information of CORESET#0, or based on other default beam schemes.
