Description

Information determination method, device and terminal

Technical Field

The application belongs to the technical field of communication, and particularly relates to an information determination method, an information determination device and a terminal.

Background

The current art introduces a new Transmission Configuration Indication (TCI) structure, using the same beam for multiple channels, which may be referred to as a common beam. The network indicates that the beam can be used for multiple channel transmission using a Media Access Control Element (MAC CE) or Downlink Control Information (DCI).

The control resource set CORESET (i.e., CORESET # 0) having ID 0 is configured by a Physical Broadcast Channel (PBCH) (configured by a Master Information Block (MIB)) for a terminal to receive System Information (SI). For a Physical Downlink Control Channel (PDCCH), the terminal determines which Synchronization Signal/Physical broadcast Channel Signal block (SSB) is received in a common search space (common search space). For a unicast Physical Downlink Shared Channel (PDSCH), it may be scheduled by DCI associated with CORESET #0.

In a Carrier Aggregation (CA) scenario, for a group of Carrier elements (CCs) or Bandwidth parts (BWPs), the network may indicate a common TCI state ID used to determine common quasi co-location information for at least a terminal-specific PDCCH or PDSCH and/or common uplink transmit spatial filter (spatial filter) information for at least a terminal-specific PUCCH or PUSCH. Wherein, the source reference signal (source RS) in the common TCI state ID indicated for the target CC can be configured on the target CC or other CCs. For the source reference signals in the common TCI state ID, the following features apply:

(A) One source RS in the common TCI state ID is cross CC, i.e. for all target CCs;

(B) The source RS in the common TCI state ID is per CC, and the source RS special for each CC is further related to the RS of one same quasi-co-located QCL-TypeD.

Since CORESET #0 belongs to CORESET that is not terminal-specific (non-UE-specific or non-UE-determined), the TCI state has not been determined in the prior art as to whether to be used for CORESET #0.

Therefore, the following problems exist in the prior art:

when common beam is not used for core set #0, it is not clear how to determine beam information of a channel or reference signal scheduled by DCI on core set #0.

In the CA scenario, if the source RS in the common TCI state ID is applied, it is not clear how to determine the related information of CORESET #0 on a certain CC.

As shown in fig. 2, an embodiment of the present application provides an information determining method, including:

step 201, a terminal receives a first command, where the first command is used to activate or indicate or update common beam information;

in this step, the common beam information may be determined according to a joint TCI state (joint TCI state) or a separate downlink TCI state (separate DL TCI state) or a separate uplink TCI state (separate UL TCI state) in the first command. The common beam information is used for determining common QCL information of at least a terminal-specific PDCCH or PDSCH and/or a terminal-specific PUCCH or PUSCH;

In this step, the second command and the first command may be the same command, that is, one command indicates the common beam information and the first beam information; alternatively, the first command and the second command are different commands, that is, the common beam information and the first beam information are respectively indicated by different commands.

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

In step 203, the terminal determines the parameter information of the common search space of the carrier cell CC configured with the CORESET #0 or the CORESET #0 on the bandwidth portion BWP, or determines the beam information used by the channel or the reference signal scheduled by the downlink control information on the CORESET #0 according to the common beam information or the first beam information.

Optionally, the first beam information may also be used for a channel related to core set #0, such as a channel where feedback information (e.g., HARQ-ACK information) of the PDCCH scheduled on core set #0, the PUSCH scheduled on PDCCH scheduled on core set #0, the PDSCH scheduled on PDCCH scheduled on core set #0, and the channel where feedback information (e.g., HARQ-ACK information) of the PDCCH scheduled on core set #0 is located.

In at least one optional embodiment of the present application, in a carrier aggregation CA scenario, the common beam information includes: the common transmission configuration indicates a TCI state identification (e.g., a common TCI state ID) that applies to at least one channel or reference signal on a group of CCs or BWPs. The terminal may determine beam information of a first channel or a first reference signal on a set of CCs or BWPs according to the common TCI state ID.

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

Alternatively, the common TCI state ID may be an ID of a joint TCI state activated or indicated by the first command or updated, or an ID of a downstream TCI state alone, or an ID of an upstream TCI state alone, which is not particularly limited herein.

Correspondingly, in a carrier aggregation CA scenario, the first beam information includes: a first TCI state identification (e.g., a first TCI state ID) that applies to CORESET #0 across a group of CCs or BWPs. The terminal determines the beam information of CORESET #0 on a group of CC or BWP configured by the network according to the first TCI state ID.

It should be noted that CORESET #0 is configured on at least one specific CC or BWP in the above-mentioned group of CC or BWP; that is, not every CC or BWP in a set of CCs or BWPs has CORESET #0 configured thereon.

Alternatively, the first TCI state ID may be the same as or different from the common TCI state ID.

Optionally, the first TCI state ID may be a common TCI state ID or a non-common TCI state ID.

Optionally, the first TCI state ID may also be used for a channel related to core set #0, such as a PDCCH on core set #0, a PDSCH scheduled by the PDCCH on core set #0, a PUSCH scheduled by the PDCCH on core set #0, a channel where feedback information (such as HARQ-ACK information) of the channel scheduled by the PDCCH on core set #0 is located, and the like.

In at least one optional embodiment of the present application, in a CA scenario, in step 203, the terminal determines, according to the common beam information or the first beam information, parameter information of a common search space of the carrier cell CC or the bandwidth portion BWP where the CORESET #0 is configured, where the parameter information includes:

the terminal determines a reference signal of a quasi-co-location QCL type D of CORESET #0 on CC or BWP configured with CORESET #0 according to the public TCI state identifier or the first TCI state identifier;

the terminal determines a first reference signal according to the determined reference signal of QCL type D;

and the terminal determines the parameter information of the common search space of the CORESET #0 on the CC or BWP configured with the CORESET #0 according to the first reference signal or the synchronization signal block SSB related to the first reference signal.

It should be noted that when the QCL type is QCL type D (QCL-type), { Spatial RX parameter } corresponding to QCL-type represents beam information.

As an alternative embodiment, the determined reference signal of QCL type D may be per-CC or BWP based (i.e. the reference signal of QCL type D determined by the terminal includes the respective reference signal of QCL type D of CORESET #0 on each CC or BWP where CORESET #0 is configured). For example, the network has CORESET #0 disposed on CC0, CC1, CC2, and CC3, QCL-TypeD RS of CORESET #0 on CC0 is TRS0 on CC0, QCL-TypeD RS of CORESET #0 on CC1 is TRS1 on CC1, QCL-TypeD RS of CORESET #0 on CC2 is TRS2 on CC2, QCL-TypeD RS of CORESET #0 on CC3 is TRS3 on CC 3.

As another alternative, the reference signal of the determined QCL type D may also be a reference signal of a common QCL type D of all CORESET #0 (i.e. the reference signal of the QCL type D determined by the terminal includes a reference signal of a common QCL type D of all CORESET #0 on the CC or BWP where CORESET #0 is configured). For example, the network configures CORESET #0 on CC0, CC1, CC2, CC3, and QCL-type RS of CORESET #0 on these 4 CCs are all TRS0 on CC 0.

In at least one optional embodiment of the present application, the determining, by the terminal, the reference signal of the quasi-co-located QCL type D of the CORESET #0 on the CC or the BWP configured with the CORESET #0 according to the common TCI state identifier or the first TCI state identifier includes:

under the condition that the first TCI state identifier is the same as the public TCI state identifier, the terminal determines the reference signal of the QCL type D of CORESET #0 on CC or BWP which is configured with CORESET #0 according to the public TCI state identifier.

Alternatively, the first and second electrodes may be,

and under the condition that the first TCI state identifier is different from the public TCI state identifier, the terminal determines the reference signal of the QCL type D of CORESET #0 on CC or BWP which is configured with CORESET #0 according to the first TCI state identifier.

In at least one optional embodiment of the present application, the determining, by the terminal, the first reference signal according to the determined reference signal of QCL type D includes:

the reference signals of QCL type D determined at the terminal include: when the reference signal of the QCL type D of the CORESET #0 on each CC or BWP of the CORESET #0 is configured, determining the same reference signal associated with the reference signal of each QCL type D as the first reference signal; optionally, the first reference signal is SSB. Optionally, the QCL type of the first reference signal is QCL type D.

For example, the reference signals of QCL type D determined are: and in the TCI state determined according to the common TCI state ID or the first TCI state ID, the RS resource determined on each CC/BWP by the RS resource ID with the type of QCL-type in reference signal (or source RS) in the QCL message is used as the QCL-type RS (reference signal of QCL type D) of CORESET #0 on the CC/BWP.

The QCL-TypeD RSs of CORESET #0 on each CC or BWP have a QCL relationship, and these QCL-TypeD RSs are associated to the same first reference signal. As an alternative embodiment, the same reference signal (i.e. the first reference signal) associated with the reference signal of each QCL type D comprises:

configuring a reference signal of one QCL type D in reference signals of the respective QCL types D of the CORESET #0 on each CC or BWP of the CORESET # 0;

alternatively, the first and second electrodes may be,

the reference signal of QCL type D of CORESET #0 on each CC or BWP of CORESET #0 is configured.

In short, in this scenario, the first reference signal may be one of the QCL-type RSs of the CORESET #0 or the QCL-type RSs of the CORESET #0 on each CC or BWP where the CORESET #0 is configured.

For example, the network has CORESET #0 disposed on CC0, CC1, CC2, and CC3, QCL-TypeD RS of CORESET #0 on CC0 is TRS0 on CC0, QCL-TypeD RS of CORESET #0 on CC1 is TRS1 on CC1, QCL-TypeD RS of CORESET #0 on CC2 is TRS2 on CC2, QCL-TypeD RS of CORESET #0 on CC3 is TRS3 on CC 3.

Then, TRS0 on CC0 may be a common QCL-type RS for TRS1, TRS2, TRS3, or TRS1, TRS2, TRS3 may all be associated with TRS0. At this time TRS0 is the first reference signal. If the QCL-type RS of CORESET #0 on CC0 is the SSB on CC0, the SSB may also be the common QCL-type RS of TRS1, TRS2, TRS3, or TRS1, TRS2, TRS3 are all associated with the SSB, and the SSB on CC0 is the first reference signal.

Alternatively, the QCL-TypeRS of CORESET #0 on the 4 CCs, i.e., the common QCL-TypeRS of TRS0, TRS1, TRS2, TRS3, is the SSB on CC0, or associated to CC 0. The SSB on CC0 is the first reference signal.

As another alternative embodiment, the first reference signal is configured on a first reference CC or a first reference BWP in a group of CCs or BWPs corresponding to the common TCI state identification;

alternatively, the first and second electrodes may be,

the first reference signal is configured on a second reference CC or a second reference BWP in a group of CC or BWP corresponding to the first TCI state identification;

alternatively, the first and second electrodes may be,

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

the reference signals of QCL type D determined at the terminal include: and under the condition that the reference signals of the common QCL type D of all CORESET #0 on the CC or BWP configured with CORESET #0, determining the reference signals of the common QCL type D as the first reference signals.

For example, the reference signals of QCL type D determined are: in the TCI state determined according to the common TCI state ID or the first TCI state ID, RS resource with the type of QCL-type in reference signal (or source RS) in the QCL message is the common QCL-type RS of all CORESET #0.

For example, the network configures CORESET #0 on CC0, CC1, CC2, and CC3, and QCL-type RSs of CORESET #0 on these 4 CCs are all TRS0 on CC0, so this TRS0 is the first reference signal. If the QCL-type RS of CORESET #0 on the 4 CCs are all SSBs on CC0, then the SSBs are the first reference signals.

As another alternative embodiment, the first reference signal (i.e., the reference signal of the common QCL type D) is configured on a first reference CC or a first reference BWP in a set of CCs or BWPs corresponding to the common TCI state identification;

alternatively, the first and second electrodes may be,

the first reference signal (i.e., a reference signal of common QCL type D) is configured on a second reference CC or a second reference BWP in a set of CCs or BWPs corresponding to the first TCI state identification;

alternatively, the first and second electrodes may be,

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

As another optional embodiment, the determining, by the terminal, the first reference signal according to the determined reference signal of QCL type D includes:

and determining the reference signal of QCL type A as the first reference signal under the condition that the reference signal of QCL type D determined by the terminal is not SSB. In other words, the parameter information of the common search space (which may be referred to as searching space #0 or SS # 0) of the CORESET #0 in the embodiment of the present application depends on the reference SSB (which is the first reference signal or the SSB associated with the first reference signal), and the reference SSB is any one of the following items:

if the reference signals of QCL type D of CORESET #0 in CA are on a per CC or BWP basis, then the SSB with which these reference signals of QCL type D are commonly associated is taken as the reference SSB;

if the reference signal of QCL type D of CORESET #0 in CA is the reference signal of the same QCL type D of all CCs or BWPs, then using the reference signal of the same QCL type D or its associated SSB as the reference SSB;

if the reference signal of QCL type D of CORESET #0 in CA is not SSB, the reference signal of QCL type a or its associated SSB is taken as the reference SSB.

As an alternative embodiment, the reference signal of QCL type D comprises at least one of:

a synchronization signal block SSB;

And the terminal determines a monitoring occasion according to the mapping relation (or called association relation) between the SSB and the CORESET and/or the search space, and monitors the PDCCH at the monitoring occasion.

in the case that the first beam information is the same as the common beam information, and a time interval between downlink control information on the CORESET #0 and a channel or a reference signal scheduled by the downlink control information is smaller than a preset threshold (or referred to as that a transmission time of the channel or the reference signal is earlier than an application time of the first beam information), determining that the beam information used by the channel or the reference signal includes at least one of:
