Description

Technical Field
The present invention relates to the field of communications technologies, and in particular, to an information transceiving method and apparatus, a storage medium, and a terminal.
Background
In a New Radio (NR) standard text (Rel-15/Rel-16), for codebook-based Uplink transmission, a Downlink Control Information (DCI) of a scheduling node includes a Sounding Reference Signal Resource Indicator (SRI) field, and a terminal can obtain spatial Information of a Physical Uplink Shared Channel (PUSCH) and antenna port Information for determining Precoding Information of the PUSCH according to the SRI field, so as to obtain a Precoding Matrix Indicator (TPMI) based on the antenna port Information. If the network does not enable the terminal to transmit with full power, the antenna port information can be acquired through a high layer such as Radio Resource Control (RRC); however, if the network enables full power transmission by the terminal, especially full power transmission mode 2, the antenna port information needs to be available from the SRI field in the DCI.
In NR Rel-15/Rel-16, for uplink transmission based on a non-codebook, the scheduling DCI thereof includes an SRI field, and the terminal can acquire spatial information of a PUSCH and rank information of the PUSCH according to the SRI field, thereby acquiring Demodulation Reference Signal (DMRS) information for the PUSCH based on the rank information.
In NR Rel-15/16, the downlink is to acquire related Transmission information, such as spatial information, through a Transmission Configuration Indicator (TCI) state.
In the future standard protocol, as Rel-17, a unified TCI status-based indication framework for uplink and downlink is supported, that is, for uplink transmission, the scheduling DCI thereof, such as DCI0_1/DCI 0_2, may no longer include an SRI field, and instead a transmission configuration indication TCI field, whereas in Rel-15/16, the TCI field is used to indicate relevant transmission information, such as spatial domain information, Doppler spread, Doppler shift, delay spread, average delay, that is, for uplink transmission, if the unified TCI status-based indication framework for uplink and downlink is supported, a problem that antenna port information for determining precoding information for PUSCH cannot be obtained, or rank information for PUSCH cannot be determined easily occurs.

Detailed Description
As mentioned above, in the future standard protocol, for example, Rel-17 stands to support the unified TCI state-based beam indication framework for uplink and downlink, that is, for uplink transmission, the scheduling DCI thereof, such as DCI0_1/DCI 0_2, may no longer include the SRI field, and instead may include the transmission configuration indication state TCI field, whereas in Rel-15/16, the TCI field is used to indicate the relevant transmission information, such as spatial information, Doppler spread (Doppler spread), Doppler shift (Doppler shift), delay spread (delay spread), and average delay (average delay), that is, for uplink transmission, if the unified TCI state-based indication framework for uplink and downlink is supported, the problem of being unable to determine the antenna port information of the precoding information for PUSCH or being unable to determine the rank information of PUSCH is easily generated. The inventor of the present invention finds, through research, that for uplink transmission based on a codebook, according to a TCI field in scheduling DCI thereof, a terminal can only know spatial domain information of a PUSCH, but cannot specifically know antenna port information thereof for determining precoding information of the PUSCH; for uplink transmission based on non-codebook, according to the TCI field in the scheduling DCI, the terminal can only know the spatial domain information of PUSCH, but cannot know the rank (rank) information thereof.
In the embodiment of the invention, the configuration information of the CORESET is obtained, wherein the configuration information of the CORESET comprises first TCI state information; and receiving and/or sending information according to the first TCI state information. By adopting the scheme, compared with the prior art that the antenna port information used for determining the precoding information of the PUSCH cannot be obtained or the rank information of the PUSCH cannot be determined by setting and acquiring the configuration information of the CORESET containing the first TCI state information, by adopting the scheme of the embodiment of the invention, the antenna port information used for determining the precoding information of the PUSCH scheduled by the PDCCH and/or the rank information of the PUSCH scheduled by the PDCCH can be determined directly or indirectly according to the first TCI state information.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, fig. 1 is a flowchart of a first information transceiving method in an embodiment of the present invention. The first information transceiving method may include steps S11 to S12:
step S11: acquiring configuration information of CORESET, wherein the configuration information of CORESET comprises first TCI state information;
step S12: and receiving and/or sending information according to the first TCI state information.
In a specific implementation of step S11, TCI status (State) information of a Control Resource Set (Control Resource Set, core) may be configured.
Specifically, taking NR Rel-15/16 as an example, it is supported that a Media Access Control (MAC) Control unit (Control Element, CE) configures a TCI state of CORESET 0.
In a specific implementation of step S12, the information transceiving method in this embodiment of the present application receives and/or transmits information according to the first TCI status information.
In the embodiment of the present invention, by setting and acquiring configuration information of CORESET including first TCI status information, compared with the prior art in which either antenna port information used for determining precoding information of a PUSCH scheduled by a PDCCH cannot be determined or rank information of the PUSCH cannot be determined, by adopting the scheme of the embodiment of the present invention, there is an opportunity to directly or indirectly determine antenna port information used for determining precoding information of a PUSCH scheduled by a PDCCH and/or rank information of a PUSCH scheduled by a PDCCH according to the first TCI status information.
Further, if the configuration information of the CORESET indicates that the CORESET is CORESET0, and the QCL-TypeD reference signal indicated by the first TCI state information is an SRS, the SRS and the SSB have a Quasi co-location (QCL) relationship.
Specifically, the RSs included in the TCI state in NR Rel-15/16 are all downlink RSs, such as: when the TCI state configured by the CORESET0 includes an RS that is a CSI-RS, or an SSB, to ensure consistency between the idle-state UE and the connected-state UE, the protocol further specifies that the CSI-RS has a QCL relationship with the SSB.
In a future standard protocol, for example, Rel-17 establishment supports a unified TCI State-based indication framework for uplink and downlink, that is, Reference Signals (RS) included in a TCI State may include uplink signals, such as SRS, in addition to downlink signals, that is, RS included in a TCI State may be Synchronization Signal Block (SSB), Channel State Information Reference Signal (CSI-RS), or SRS, so that when RS included in a TCI State configured by CORESET0 is SRS, it may be difficult to ensure consistency between idle-State UE and connected-State UE if no further constraint condition is set.
In the embodiment of the present invention, the configuration information set in the CORESET indicates that the CORESET is CORESET0, the reference signal of Quasi-co-location type D (QCL-type D) indicated by the first TCI state information is SRS, and the SRS and the SSB have a QCL relationship, compared with the prior art, only the case where the RSs are downlink RSs is specified, and the specification of the case where the RSs include both downlink signals and uplink signals is lacked.
Referring to fig. 2, fig. 2 is a partial flowchart of a second information transceiving method according to an embodiment of the present invention. The second information transceiving method may include steps S11 to S12 shown in fig. 1, and may further include steps S21 to S22, each of which is described below.
It should be noted that the sequence numbers of the steps in this embodiment do not represent a limitation on the execution sequence of the steps. For example, steps S21 to S22 may be performed between steps S11 to S12, and may also be performed after step S12.
In step S21, the PDCCH is received and/or demodulated according to the first TCI status information.
In step S22, antenna port information used for determining precoding information of a PUSCH scheduled by the PDCCH is obtained at least according to the DCI in the PDCCH.
In the embodiment of the present invention, the antenna port information used for determining the precoding information of the PUSCH scheduled by the PDCCH is obtained at least according to the DCI in the PDCCH, and compared with the case that the antenna port information used for determining the precoding information of the PUSCH may not be determined in the prior art, by adopting the scheme of the embodiment of the present invention, the antenna port information used for determining the precoding information of the PUSCH can be accurately determined.
In a specific implementation manner of the embodiment of the present invention, the step of obtaining, at least according to DCI in the PDCCH, antenna port information used for determining precoding information of a PUSCH scheduled by the PDCCH may include: and if the DCI is used for codebook-based uplink transmission and the QCL-TypeD reference signal indicated by the second TCI state information contained in the DCI is SRS, the number of ports of the SRS is antenna port information used for determining the precoding information of the PUSCH scheduled by the PDCCH.
It should be noted that, in the embodiment of the present application, in order to distinguish the TCI status information included in the configuration information of the CORESET from the TCI status information included in the DCI, the first TCI status information is used to represent the TCI status information included in the configuration information of the CORESET, and the second TCI status information is used to represent the TCI status information included in the DCI.
In another specific implementation manner of the embodiment of the present invention, the step of obtaining, at least according to the DCI in the PDCCH, antenna port information used for determining precoding information of a PUSCH scheduled by the PDCCH may include: and if the DCI is used for codebook-based uplink transmission and a QCL-TypeD reference signal indicated by second TCI state information contained in the DCI is a CSI-RS, the number of ports of the CSI-RS is antenna port information used for determining precoding information of a PUSCH scheduled by the PDCCH.
In the embodiment of the present invention, by setting the second TCI status information included in the DCI to determine the antenna port information used for determining the precoding information of the PDCCH-scheduled PUSCH, compared with the case that the antenna port information used for determining the precoding information of the PDCCH-scheduled PUSCH may not be determined in the prior art, by using the scheme of the embodiment of the present invention, the antenna port information used for determining the precoding information of the PDCCH-scheduled PUSCH can be accurately determined.

The third information transceiving method may include steps S11 to S12 shown in fig. 1, and may further include steps S31 to S32, each of which is described below.
It should be noted that the sequence numbers of the steps in this embodiment do not represent a limitation on the execution sequence of the steps. For example, steps S31 to S32 may be performed between steps S11 to S12, and may also be performed after step S12.
In step S31, the PDCCH is received and/or demodulated according to the first TCI status information.
In a specific implementation, more details regarding step S31 are described with reference to step S21 in fig. 2, and are not described herein again.
In step S32, if the DCI in the PDCCH is used for codebook-based uplink transmission, antenna port information used for determining precoding information of a PUSCH scheduled by the PDCCH is determined according to second TCI status information included in the DCI.
Further, the step of determining antenna port information for determining precoding information of the PDCCH-scheduled PUSCH according to the second TCI status information included in the DCI may include: a preset number of bits in second TCI status information included in the DCI are used to indicate the antenna port information used to determine the precoding information of the PUSCH scheduled by the PDCCH.
Further, the DCI may include a preset number of bits of the second TCI status information, which are 1MSB bits or 1LSB bits.
As a non-limiting example, if the downlink control information is used for codebook-based uplink transmission and the terminal obtains the port information through the TCI field, one possible way is as follows:
if the higher layer parameters (e.g., TCI-PresentInDCI) are not enabled, then the TCI field contains 1 bit, e.g., X 0 If X is 0 0 indicates that the port number is 2, and if X0 is 1, the port number is 4; otherwise, if the higher layer parameters (e.g., TCI-PresentInDCI) are enabled, the TCI field contains 4 bits, such as X 0 X 1 X 2 X 3 Where X0 is used to represent port number information and X1X2X3 bits of 3 are used to indicate TCI status.
In the embodiment of the present invention, by setting the second TCI status information included in the DCI, determining the antenna port information used for determining the precoding information of the PDCCH-scheduled PUSCH, compared with the case that the antenna port information used for determining the precoding information of the PDCCH-scheduled PUSCH may not be determined in the prior art, by using the scheme of the embodiment of the present invention, the antenna port information used for determining the precoding information of the PDCCH-scheduled PUSCH can be accurately determined.

In step S41, the PDCCH is received and/or demodulated according to the first TCI status information.
In a specific implementation, more details regarding step S41 are described with reference to step S21 in fig. 2, and are not described herein again.
In step S42, if the DCI in the PDCCH is used for codebook-based uplink transmission, antenna port information used for determining precoding information of a PUSCH scheduled by the PDCCH is determined according to coding information and a layer number field of the PDCCH.
