Description

TCI state indication method, terminal and network side equipment

Technical Field

The embodiment of the invention relates to the technical field of wireless communication, in particular to a Transmission Configuration Indicator (TCI) state indication method, a terminal and network side equipment.

Background

The following describes several related terms of communication:

1. quasi co-location (QCL-Quasi-location)

Quasi-co-location, refers to signals having the same channel characteristics between different channels, which can be assumed to originate from the same transmission source. QCL configurations may include a variety of different Signal types, such as Channel State Information-Reference Signal (CSI-RS) or Synchronization Signal Block (SSB) or Sounding Reference Signal (SRS). The network side device may configure its corresponding QCL configuration for different beams. The network side device may change the beam on which the terminal operates by changing the QCL configuration of the terminal (UE).

2. Beam management (Beam management)

The beam management comprises: beam measurement, beam reporting, beam indication, etc. The network side device configures setting information (reporting setting) of a beam report (beam reporting) for the terminal through high-level signaling, wherein the setting information includes content information of the beam report, time domain related messages (periodic, aperiodic and semi-persistent) of the beam report, frequency domain granularity (frequency granularity) information of the beam report, and the like. The content information in the beam reporting (beam reporting) may include: at least one optimal transmit beam identification information selected by the terminal, physical layer measurement results (e.g., L1-RSRP) of beams selected by the terminal, grouping information of beams selected by the terminal, etc. There are three cases of configuring reference signals for downlink beam measurement: SSB only, CSI-RS only, SSB + CSI-RS. Wherein the CSI-RS refers to a terminal-specific (UE-specific) configuration, not a cell-specific (cell-specific) configuration.

3. Semi-static reference signals for beam management

Semi-static Channel State Information-Reference Signal (SP CSI-RS), a Channel State Information Reference Signal (NZP CSI-RS) for measuring non-zero power of interference.

Semi-static Channel State Information-interference measurement (SP CSI-IM), generally referred to as zero-power interference measurement (ZP CSI-RS).

Semi-static Sounding Reference Signal (SP SRS) is used for quality measurement of uplink channel, such as measurement of received power and Channel Quality Indicator (CQI).

The SP CSI-RS, the SP CSI-IM and the SP SRS resource configuration (resource setting) used for channel measurement all comprise one or more resource sets (resource sets), and each resource set comprises a plurality of resources (resource).

4. Transmission Configuration Indicator (TCI) status (state)

The TCI state is used to dynamically indicate a QCL spatial relationship (relationship) between reference signals in one reference signal set and a Physical Downlink Shared Channel (PDSCH) demodulation reference signal (DMRS) port (port).

The contact function sent by the 3GPP RAN1 to the RAN2 expects that the RAN2 designs several media access control layer control units (MAC CEs), and the network side device indicates to activate/deactivate the SP CSI-RS resource set, the SP CSI-IM resource set, and the SP SRS resource set of the terminal by issuing the MAC CEs.

Currently, 3GPP has correspondingly completed the design of MAC CEs related to several beam management (beam management) in the contact function, wherein for SP CSI-RS resource set/SP CSI-IM resource set and SP SRS resource set, in addition to designing MAC CEs for activation/deactivation, it needs to provide corresponding QCL spatial relationship in the activated state.

In the current protocol, the specification of the carrying condition of the TCI state in the MAC CE for activation/deactivation of the SP CSI-RS/CSI-IM resource set and the SP SRS resource set is incomplete, on the other hand, the current 3GPP conference has agreed to support the uplink cross-carrier beam indication uplink spatial information indication, but the current corresponding MAC CE format does not provide the functional indication, so that the terminal cannot accurately process the received MAC CE for activation/deactivation.

The contact function sent by the 3GPP RAN1 to the RAN2 expects that the RAN2 designs several MAC CEs, and the network side device instructs to activate/deactivate the SP CSI-RS resource set, the SP CSI-IM resource set, and the SP SRS resource set of the terminal by issuing the MAC CEs.

At present, 3GPP has correspondingly completed the design of MAC CE related to several beam management (beam management) in the contact function, please refer to table 1.

TABLE 1

For the SP CSI-RS resource set/SP CSI-IM resource set and the SP SRS resource set, in addition to designing the MAC CE for activation/deactivation, it is also necessary to provide a corresponding QCL spatial relationship in an activated state.

Referring to FIG. 2, FIG. 2 is a format of a MAC CE for activating/deactivating a set of SP CSI-RS/CSI-IM resources, and as can be seen from FIG. 2, "TCI State ID" in the MAC CE for activating/deactivating a set of SP CSI-RS/CSI-IM resources_iAnd the field is used for indicating whether the MAC CE carries TCI state information of the QCL spatial relationship of each resource in the SP CSI-RS/CSI-IM resource set. An "a/D" field in the MAC CE in fig. 2 is used to indicate to activate or deactivate the SP CSI-RS/CSI-IM resource set, and when the "a/D" field is set to 0, to indicate to deactivate the SP CSI-RS/CSI-IM resource set, at this time, the MAC CE does not carry the "TCI State ID_iA field for indicating activation of SP CSI-RS/CSI-IM resource set when the A/D field is set to 1, wherein the MAC CE carries a TCI State ID_i"field.

Referring to fig. 3, fig. 3 shows a format of a MAC CE for activating/deactivating a set of SP SRS resources, and as can be seen from fig. 3, F in the MAC CE for activating/deactivating the set of SP SRS resources_i"and" Resource ID_i"field for collectively indicating TCI status information of QCL spatial relationship for each resource in the set of SP SRS resources in the MAC CE. An "A/D" field in the MAC CE in FIG. 3 for indicating activation or deactivation of the SP CSI-RS/CSI-IM resource set, when the "A/D" field is set to 0Indicating to deactivate SP SRS resource set, at this time, the MAC CE does not carry' F_i"and" Resource ID_iA field indicating activation of SP SRS resource set when the A/D field is set to 1, wherein the MAC CE carries' F_i"and" Resource ID_i"field.

However, the existing protocol does not completely explain the carrying conditions of the TCI states in the MAC CEs for activation/deactivation in the SP CSI-RS/CSI-IM resource set and the SP SRS resource set, so that the terminal cannot accurately process the received MAC CEs for activation/deactivation.

To solve the above problem, referring to fig. 4, an embodiment of the present invention provides a TCI status indication method, where the TCI status indication method is applied to a terminal, and includes:

step 41: receiving RRC configuration information, wherein the RRC configuration information indicates whether TCI state information is carried in an activation/deactivation MAC CE of a semi-static reference signal resource set for beam management, and the TCI state information is used for indicating a QCL spatial relationship of the semi-static reference signal resource set;

step 42: receiving the MAC CE;

step 43: and when the TCI state information is carried by the MAC CE, judging whether to ignore the TCI state information carried by the MAC CE or not according to the RRC configuration information.

In this embodiment of the present invention, preferably, the semi-static reference signal resource set includes: a set of SP CSI-RS/CSI-IM resources or a set of SP SRS resources. Of course, in some other embodiments of the present invention, it is not excluded that the set of semi-static reference signal resources is other types of sets of semi-static reference signal resources for beam management.

The RRC configuration information in the embodiment of the present invention may be implemented in various manners, which will be described below by way of example.

Example one

When the RRC configuration information comprises configuration information of TCI state information corresponding to the MAC CE, the TCI state information is carried in the MAC CE; or

When the RRC configuration information does not include the configuration information of the TCI state information corresponding to the MAC CE, carrying or not carrying the TCI state information in the MAC CE;

that is to say, when the received RRC configuration information includes configuration information of TCI state information corresponding to the MAC CE, it indicates that the TCI state information is carried in the MAC CE received by the terminal;

when the received RRC configuration information does not include the configuration information of the TCI status information corresponding to the MAC CE, it indicates that the TCI status information may be carried in the MAC CE received by the terminal, and the TCI status information may not be carried in the MAC CE received by the terminal.

At this time, when the TCI status information is carried by the MAC CE, the step of determining whether to ignore the TCI status information carried by the MAC CE according to the RRC configuration information may include:

when the RRC configuration information comprises configuration information of TCI state information corresponding to the MAC CE and the received MAC CE carries the TCI state information, determining that the TCI state information in the MAC CE is valid;

and when the RRC configuration information does not include the configuration information of the TCI state information corresponding to the MAC CE and the received MAC CE carries the TCI state information, ignoring the TCI state information in the MAC CE.

That is, when the RRC configuration information does not include configuration information of TCI status information corresponding to the MAC CE, even if the TCI status information is carried in the MAC CE received by the terminal, the terminal does not parse the TCI status information in the MAC CE.

When the set of semi-static reference signal resources is a set of SP CSI-RS/CSI-IM resources:

when the received RRC configuration information does not include the configuration information of TCI state information corresponding to the MAC CE for activating/deactivating the SP CSI-RS/CSI-IM resource set, the MAC CE for activating/deactivating the SP CSI-RS/CSI-IM resource set does not carry the TCI state information, or the MAC CE still carries the TCI state information, but the terminal ignores the TCI state information in the MAC CE.

When the set of semi-static reference signal resources is a set of SP SRS resources:

when the received RRC configuration information does not include configuration information of TCI status information corresponding to a MAC CE for activating/deactivating an SP SRS Resource set, the MAC CE for activating/deactivating the SP SRS Resource set does not carry the TCI status information, that is, does not carry "Fi" and "Resource IDi" fields, or the MAC CE still carries the TCI status information, that is, carries "Fi" and "Resource IDi" fields, but the terminal ignores the TCI status information in the MAC CE.

Example two

One way of this embodiment is:

the RRC configuration information may include indication information, where the indication information is used to indicate whether a first MAC CE used for activating/deactivating an SP SRS resource set carries the TCI state information;

when the indication information indicates that the first MAC CE carries the TCI state information, the first MAC CE carries the TCI state information;

when the indication information indicates that the first MAC CE does not carry the TCI state information, the first MAC CE carries or does not carry the TCI state information;

the step of judging whether to ignore the TCI state information carried by the MAC CE according to the RRC configuration information when the TCI state information is carried by the MAC CE comprises the following steps:

when the indication information indicates that the first MAC CE carries the TCI state information and the received first MAC CE carries the TCI state information, determining that the TCI state information in the first MAC CE is valid;

and when the indication information indicates that the first MAC CE does not carry the TCI state information and the received first MAC CE carries the TCI state information, ignoring the TCI state information in the first MAC CE.

That is to say, when the indication information in the RRC configuration information indicates that the first MAC CE does not carry the TCI status information, even if the TCI status information is carried in the first MAC CE received by the terminal, the terminal does not parse the TCI status information in the first MAC CE.

For example, 1 bit (i.e., indication information) may be introduced into the RRC configuration information to indicate whether a first MAC CE for activating/deactivating an SP SRS Resource set carries the TCI status information, for example, when the 1 bit is set to "1", the first MAC CE is indicated to carry the TCI status information, at this time, Fi and Resource IDi fields are carried in the first MAC CE, and the first MAC CE is valid, and when the 1 bit is set to "0", the first MAC CE is indicated to not carry the TCI status information, at this time, Fi and Resource IDi fields may not be carried in the first MAC CE, or the first MAC CE still carries Fi and Resource IDi fields, but the terminal ignores the Fi and Resource IDi fields.

Another way of this embodiment is:

setting a selectable preset parameter in the RRC configuration information;

when the RRC configuration information comprises preset parameters, the TCI state information is carried in the first MAC CE for activating/deactivating the SP SRS resource set;

when the RRC configuration information does not include the preset parameter, the TCI state information is carried or not carried in the first MAC CE;

when the RRC configuration information comprises the preset parameters and the received first MAC CE carries the TCI state information, determining that the TCI state information in the first MAC CE is valid;

and when the RRC configuration information does not include the preset parameters and the received first MAC CE carries the TCI state information, ignoring the TCI state information in the first MAC CE.

That is to say, when the RRC configuration information includes the preset parameter, the Fi and Resource ID are carried in the first MAC CE received by the terminal_iA field in which a terminal determines Fi and Resource ID in the first MAC CE_iThe field is valid.

When the RRC configuration information does not include the preset parameter, the F is not carried in the first MAC CE received by the terminal_iAnd Resource ID_iField, or the first MAC CE received by the terminal still carries the F_iAnd Resource ID_iField, but terminal ignores F in said first MAC CE_iAnd Resource ID_iA field.

EXAMPLE III

The RRC configuration information includes bitmap indication information, where the bitmap indication information is used to indicate whether each resource in the semi-static reference signal resource set in the MAC CE is carried in the MAC CE.

Each bit in the bitmap indication information is used to indicate whether each resource in the semi-static reference signal resource set is carried in the MAC CE. For example, a bit position "1" indicates that the MAC CE carries the resource corresponding to the bit, and a bit position "0" indicates that the MAC CE does not carry the resource corresponding to the bit.

That is, in the RRC signaling, whether each resource in the semi-static reference signal resource set in the MAC CE is carried in the MAC CE is explicitly determined in a bitmap (bitmap) form, so that whether the TCI state information of each resource in the semi-static reference signal resource set is carried in the MAC CE is implicitly described.

The length of the bitmap indication information is equal to the number of resources in the semi-static reference signal resource set.

and the length of bitmap indication information in the RRC configuration information is equal to the number of resources in the SP CSI-RS resource set in the MAC CE for activating/deactivating the SP CSI-RS/CSI-IM resource set.

Existing protocols specify: there are 16 CSI-RS resource sets (resource sets) at most in the CSI-RS resource configuration (resource setting) configured for the terminal, and there are 64 resources (resource) in each resource set at most. The number of all different CSI-RS resources in the total set of resources does not exceed 128.

That is, the bit number of the bitmap indication information corresponding to the SP CSI-RS/CSI-IM resource set does not exceed 64.

and the length of bitmap indication information in the RRC configuration information is equal to the number of resources in the SP SRS resource set in the MAC CE for activating/deactivating the SP SRS resource set.

The bit number of bitmap indication information corresponding to the SP SRS resource set is 64.

At present, the RAN1 has agreed to support cross-carrier beam indication spatial relationship, and thus the format of the first MAC CE for activating/deactivating the SP SRS resource set at present cannot flexibly indicate which cell and which BWP correspond to the spatial relationship.

Example four

In order to solve the above problem, in the embodiment of the present invention, a first MAC CE for activating/deactivating an SP SRS resource set carries a first indication field, where the first indication field is used to indicate Cell IDs and BWP IDs corresponding to QCL spatial relationships of all resources in the SP SRS resource set.

In the embodiment of the present invention, the QCL spatial relationship in the MAC CE is configured based on the Resource set (i.e., Resource set level configuration), and the QCL spatial relationship of all resources in the SP SRS Resource set corresponds to the same Cell ID and the same BWP ID.

Referring to fig. 5, in the embodiment of the present invention, a "Serving Cell ID for Cross-carrier" and a "BWP ID for Cross-carrier" field are added to a MAC CE for activating/deactivating an SP SRS resource set, and are used to indicate Cell IDs and BWP IDs corresponding to QCL spatial relationships of all resources of the SP SRS resource set.

EXAMPLE five

The first MAC CE carries a second indication field, where the second indication field is used to indicate a Cell ID and a BWP ID corresponding to a QCL spatial relationship of each resource in the SP SRS resource set.

In the embodiment of the present invention, the QCL spatial relationship in the MAC CE is based on Resource configuration (i.e., Resource level configuration), and the QCL spatial relationship of each Resource in the SP SRS Resource set corresponds to a Cell ID and a BWP ID.

Referring to fig. 6, in the embodiment of the present invention, a "Serving Cell ID for Cross-carrier i" and a "BWP ID for Cross-carrier i" field are added to a MAC CE for activating/deactivating an SP SRS resource set, and are used to indicate a Cell ID and a BWP ID corresponding to a QCL spatial relationship of each resource of the SP SRS resource set. For example, "Serving Cell ID for Cross-carrier 0" and "BWP ID for Cross-carrier 0" corresponding to the QCL spatial relationship of the first resource of the SP SRS resource set, and "Serving Cell ID for Cross-carrier 1" and "BWP ID for Cross-carrier 1" corresponding to the QCL spatial relationship of the second resource of the SP SRS resource set. N in fig. 6 is the number of resources in the SP SRS resource set.

EXAMPLE six

A first MAC CE used for activating/deactivating an SP SRS resource set carries a third indication field, wherein the third indication field is used for indicating whether a QCL spatial relationship carried by the first MAC CE is a cross-carrier beam indication;

specifically, on the basis of the fourth and fifth embodiments, 1 bit may be used to indicate whether the QCL spatial relationship carried by the first MAC CE is a cross-carrier beam indication, for example, one of R bits (c-R) of the second byte of the MAC CE is used to indicate, as shown in fig. 7 and 8.

When the third indication field indicates that the QCL spatial relationship carried by the first MAC CE is a cross-carrier beam indication, the first MAC CE carries a Cell ID and a BWP ID corresponding to the QCL spatial relationship indicated by the cross-carrier beam;

when the third indication field indicates that the QCL spatial relationship in the first MAC CE is not a cross-carrier beam indication, the first MAC CE carries or does not carry a Cell ID and a BWP ID corresponding to the QCL spatial relationship indicated by the cross-carrier beam;

wherein the method further comprises:

when the third indication field indicates that the QCL spatial relationship in the first MAC CE is a cross-carrier beam indication, determining that a Cell ID and a BWP ID corresponding to the received QCL spatial relationship indicated by the cross-carrier beam in the first MAC CE are valid;

when the third indication field indicates that the QCL spatial relationship in the first MAC CE is not a cross-carrier beam indication and the received first MAC CE includes a Cell ID and a BWP ID corresponding to the QCL spatial relationship indicated by the cross-carrier beam, ignoring the Cell ID and the BWP ID corresponding to the QCL spatial relationship indicated by the cross-carrier beam in the first MAC CE.

EXAMPLE seven

A first MAC CE for activating/deactivating a set of SP SRS resources carries a fourth indication field, where the fourth indication field is used to indicate whether a QCL spatial relationship of each resource in the set of SP SRS resources in the first MAC CE is a cross-carrier beam indication; that is, the QCL spatial relationship of each Resource in the SP SRS Resource set in the first MAC CE is configured based on a Resource (Resource level), and whether the QCL spatial relationship of each Resource is indicated by a cross-carrier beam is indicated in a bitmap manner.

When the fourth indication field indicates that the QCL spatial relationship of a certain resource in the SP SRS resource set is a cross-carrier beam indication, the first MAC CE carries a Cell ID and a BWP ID corresponding to the QCL spatial relationship of the certain resource indicated by the cross-carrier beam;

when the fourth indication field indicates that the QCL spatial relationship of a certain resource in the SP SRS resource set is not a cross-carrier beam indication, the Cell ID and the BWP ID corresponding to the QCL spatial relationship of the certain resource are the Cell ID and the BWP ID applied by the first MAC CE.

For example, when a fourth indication field corresponding to a certain resource is set to "1", it indicates that the QCL spatial relationship of the certain resource is a cross-carrier beam indication, and the first MAC CE carries a Cell ID and a BWP ID corresponding to the QCL spatial relationship of the certain resource indicated by the cross-carrier beam; when a fourth indication field corresponding to a certain resource is set to "0", it indicates that the QCL spatial relationship of the certain resource is not the cross-carrier beam indication, and the Cell ID and the BWP ID corresponding to the QCL spatial relationship of the certain resource are the Cell ID and the BWP ID applied by the first MAC CE.

Referring to fig. 9, RS-0 and RS-1 … … RS-N in fig. 9 are the fourth indication fields mentioned above, which are used to respectively indicate whether the QCL spatial relationship of each resource in the SP SRS resource set in the first MAC CE is a cross-carrier beam indication. In fig. 9, N indicates the number of resources in the SP SRS resource set in the MAC CE, and m indicates the number of RS-id fields set to 1.

Example eight

A first MAC CE used for activating/deactivating the SP SRS resource set carries a fifth indication field, wherein the fifth indication field is used for indicating the activation or deactivation of the SP SRS resource set;

when the fifth indication field indicates that the SP SRS resource set is deactivated, the first MAC CE does not carry the Cell ID and the BWP ID corresponding to the QCL spatial relationship indicated by the cross-carrier wave beam.

That is, the fifth indication field may be an a/D field in the MAC CE in the fourth to seventh embodiments, and when the a/D field indicates deactivation, none of the "Serving Cell ID for cross-carrier" and the "BWP ID for cross-carrier" fields in the MAC CE in the fourth to seventh embodiments exist.
