Description

Information indication and processing method and device, network equipment and terminal equipment

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to an information indication and processing method, an apparatus, a network device, and a terminal device.

Background

One UE in a Multi-transmission reception point (Multi-TRP) transmission is simultaneously served by a plurality of TRPs, and a high-reliability transmission can be ensured but a great energy consumption overhead is caused at the base station side. In future 6G studies, as the traffic increases, the reliability requirements increase, the number of TRPs will tend to be greater, and the energy consumption overhead at the base station side will be greater.

Under the condition of low load in the system or good channel condition, the UE selects one TRP/link with the best transmission quality/group to ensure high-reliability transmission, at the moment, other TRPs enter a dormant state and instruct the UE not to monitor and close PDCCH on a dedicated control resource set (CORESET) of the TRPs, but the prior art does not support the indication of dynamic TRP on or off, and the terminal cannot update related behaviors according to the switching of the TRPs.

Some concepts related to the embodiments of the present application are first described below.

The current standard supports two TRPs simultaneously serving one UE on one Bandwidth Part (BWP), and the Multi-TRP transmission scenario of R16 is divided into a physical downlink shared channel (Physical downlink shared channel, PDSCH) under a Multiple-downlink control information (Multiple-Downlink Control Information, m-DCI) framework and PDSCH transmission under a Single-downlink control information (Single-Downlink Control Information, S-DCI) framework and Ultra-reliable and low latency communication (Ultra-Reliable and Low Latency Communications, URLLC) enhancements based on Multi-TRP/panel.

1) M-DCI: each PDSCH is transmitted through only one TRP, both TRPs scheduling the respective PDSCH independently. The network side configures control resource sets (Control Resource Set, CORESET) corresponding to two corespoolindex (0 and 1) for the UE supporting M-DCI transmission by using radio resource control (Radio resource control, RRC), and the Multi-TRP transmits respective control information on CORESET corresponding to different corespoolindex. Accordingly, the UE needs to detect the blind-detection DCI information on CORESET corresponding to both coresetpoints.

2) S-DCI: one PDSCH is scheduled over a single physical downlink control channel (Physical downlink control channel, PDCCH), each layer (layer) of the PDSCH is mapped onto only one TRP/packet, and two different data streams of the PDSCH are transmitted simultaneously from two TRPs occupying the same time frequency resource, or one of the TRPs is selected for transmission.

3) URLLC scene enhancement: the Multi-TRP is applied in PDSCH repeated transmission, two TRPs transmit two identical PDSCHs time/frequency division multiplexed, which are scheduled by one downlink DCI, wherein one codebook corresponds to two transmission configuration indication (Transmission Configuration Indicator, TCI) states (states) in the transmission configuration indication (Transmission Configuration Indication) indication field of the DCI, and the two TCI states correspond to the two TRPs, respectively.

The embodiment of the application provides an information indication, a processing method, a device, a network device and a terminal device, which are used for solving the problem that in the prior art, indication of dynamic TRP opening or closing is not supported, and a terminal cannot update behaviors according to switching of TRPs.

The method and the device are based on the same application, and because the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repetition is not repeated.

As shown in fig. 2, an embodiment of the present application provides an information indication method, which is executed by a network device, and includes:

step S201, a first signaling is sent to a terminal;

wherein the first signaling is used to indicate the turning on and/or off of at least one or a set of Transmission Reception Points (TRP).

It should be noted that, the first signaling may implement the indication of one or more TRP at the same time, or may implement the indication of one or more groups of TRP at the same time.

Optionally, the first signaling is further used for triggering a behavior after the configuration information group is switched;

after the terminal receives the first signaling, the terminal can know which configuration information group is specifically switched to, and then execute the corresponding action of the switched configuration information group.

It should be noted that, in the embodiment of the present application, the network device may be understood as one of a plurality of TRPs capable of serving a terminal, where the plurality of TRPs can coordinate, that is, each TRP notifies each other whether each TRP is turned on or off, and then is dynamically indicated by one TRP to turn on or off.

Optionally, in at least one embodiment of the present application, the first signaling carries a first indication field, where the first indication field indicates on and/or off of at least one or a set of TRP by a bit map or a code point manner.

For example, assuming that there are N TRPs, when the bit map mode is adopted for indication, the first indication field carries N bits, and each bit corresponds to an on or off state indicating one TRP, for example, when the value of a certain bit is 0, the TRP corresponding to the bit is indicated to be in an off state, and when the value of a certain bit is 1, the TRP corresponding to the bit is indicated to be in an on state; alternatively, for example, when the value of a certain bit is 1, the TRP corresponding to the bit is indicated to be in the off state, and when the value of a certain bit is 0, the TRP corresponding to the bit is indicated to be in the on state. When the code point mode indication is adopted, the value of the bit carried by the first indication field is used for indicating the index of the TRP which is specifically started.

Optionally, the first signaling includes dynamic signaling and/or Radio Resource Control (RRC) signaling.

Optionally, the dynamic signaling includes at least one of:

a group common Control Physical Downlink Control Channel (PDCCH), a non-scheduled PDCCH, a scheduled PDCCH, or a medium access Control-Control Element (MAC-CE).

Preferably, the RRC signaling is group common RRC signaling.

Optionally, the RRC signaling is carried by at least one of:

Optionally, the non-scheduled PDCCH is used for transmitting non-scheduled Downlink Control Information (DCI); for example, the non-scheduling DCI may be DCI format 2_0, DCI format 2_6, or the like.

When the first signaling is the MAC CE, the first signaling is illustrated as the first signaling of the MAC layer.

a11, a terminal;

it is understood that the first signaling is terminal specific.

A12, a terminal group;

it is understood that the first signaling is terminal group specific.

A13, a cell;

it is understood that the first signaling is cell specific.

wherein the explicit means comprises at least one of: a dormant BWP switch indication, a configuration information set indication, a TRP status indication, a TRP identification indication;

the implicit means comprises at least one of: quasi co-sited (QCL) information, PDCCH transmission location, search Space Set Group (SSSG) handover indication information, PDCCH skip indication information.

The following describes the different instruction modes in detail.

1. The first signaling indicates the turn-on and/or turn-off of at least one or a group of TRPs based on a dormant BWP switch indication

In this case, the method further comprises:

the set of configuration information includes at least one of:

a Reference Signal (RS) configuration information set, a broadcast signal configuration information set, and control resource set (CORESET) configuration information.

Optionally, in the case that the target BWP is the currently active BWP, after the indication of the first signaling takes effect, the terminal switches the configuration information on the currently active BWP; in case the target BWP is another BWP than the currently active BWP, the terminal is to switch from the currently active BWP to the other BWP after the indication of the first signaling takes effect.

It should be noted that in this application case, when the terminal device determines that the TRP is turned on or off based on the first indication domain, it needs to be determined based on the on-off state of the TRP when the first signaling is received, for example, when the first indication domain indicates the dormant BWP of TRP1, if the terminal device receives the first signaling, the terminal device determines that the TRP1 of the first indication domain is turned off when the terminal device is in the on state, and the terminal switches to the configuration information set corresponding to the dormant BWP corresponding to TRP1 on TRP 1; if the terminal equipment receives the first signaling, the TRP1 is in a closed state, the terminal equipment determines that the indication TRP1 of the first indication domain is opened, and the terminal is switched to a configuration information group associated with the TRP1 opened state on the TRP1 or resumes to activate the initial behavior on the BWP.

In this case, it can be understood that the first indication domain is a TRP indication domain, carrying TRP information that is dynamically indicated to be turned on/off; when the bit bitmap mode is adopted for indication, N bits in the TRP indication domain correspond to N or N groups of TRPs, a bit value of 0 indicates TRP to be closed, and a bit value of 1 indicates TRP to be opened. When indicated by the code point method, the value of the bit in the TRP indication domain indicates that TRP index (or TRP group index or dormant BWP index) is turned on (or off).

It should be further noted that, in this case, the association relationship between the TRP and the at least one dormant BWP acquired by the terminal device may be preconfigured, predefined or configured by the network device.

2. The first signaling indicates on/off of at least one or a group of TRPs based on the configuration information group indication

In this case, the method further comprises:

wherein each set of configuration information includes at least one of:

RS configuration information set, broadcast signal configuration information set, CORESET configuration information.

It should be noted that in this application case, when the terminal device determines that the TRP is turned on or off based on the first indication domain, the terminal device needs to be determined based on the on-off state of the TRP when the first signaling is received, for example, when the configuration information set of TRP1 is indicated in the first indication domain, if the terminal device receives the first signaling, the TRP1 is in the on state, the terminal device determines that the TRP1 is indicated to be turned off in the first indication domain, and the terminal switches to the configuration information set corresponding to TRP1 on TRP 1; if the terminal equipment receives the first signaling, the TRP1 is in a closed state, the terminal equipment determines that the indication TRP1 of the first indication domain is opened, and the terminal is switched to a configuration information group associated with the TRP1 opened state on the TRP1 or resumes to activate the initial behavior on the BWP.

In this case, it can be understood that the first indication field is a configuration information set indication field, carrying TRP information for dynamic indication on/off; when the bit map mode is adopted for indication, N bits in the configuration information group indication domain correspond to N configuration information groups, the bit value of 0 indicates that the configuration information group is deactivated, and the bit value of 1 indicates that the configuration information group is activated. When the code point indication is adopted, the value of the bit in the TRP indication domain indicates the configuration information group of the switching.

In this case, the association relationship between the at least one configuration information set acquired by the terminal device and the TRP state may be preconfigured, predefined or configured by the network device.

3. The first signaling indicates on and/or off of at least one or a group of TRPs based on TRP status indication

In this case, the method further includes:

wherein the set of configuration information includes at least one of:

In this case, it can be understood that the first indication domain is a TRP indication domain, carrying TRP information that is dynamically indicated to be turned on/off; when the bit bitmap mode is adopted for indication, N bits in the TRP indication domain correspond to indication of on (or off) of N or N groups of TRPs, a bit value of 0 indicates TRP off, and a bit value of 1 indicates TRP on. When the code point indication is adopted, the value of the bit in the TRP indication domain indicates that TRP index (or TRP group index) is turned on (or off).

When the terminal determines to turn on a certain TRP, switching to a second configuration information group corresponding to the TRP; when the terminal determines to close a certain TRP, switching to a first configuration information group corresponding to the TRP.

In this case, the association relationship between at least one set of configuration information acquired by the terminal device and the TRP state may be preconfigured, predefined or configured by the network device.

4. The first signaling indicates an indication of the opening and/or closing of at least one or a group of TRPs based on TRP identification

Alternatively, the TRP identification may be understood as a TRP index (index), or a TRP number, e.g. an index indicating TRP1 and TRP2 in a first indication field carried in a first signaling, the first signaling being used to indicate to turn off TRP1 and TRP2.

In this case, the TRP identifier is mainly used to indicate the TRP that needs to be turned off, that is, if the first signaling carries the identifier of which TRP or groups of TRPs, the terminal determines to turn off the TRP or groups of TRPs, further, the configuration information group corresponding to the TRP in the turned-off state may be preconfigured, predefined or configured by the network device, and when the terminal determines to turn off a certain TRP, the terminal switches to the configuration information group corresponding to the TRP.

The set of configuration information includes at least one of:

5. Indication of the opening and/or closing of at least one or a group of TRPs based on first information at said first signaling

Specifically, the first information is QCL information or PDCCH transmitting position; optionally, the QCL information includes Transmission Configuration Indication (TCI) status information.

In this case, the method further comprises:

wherein the set of configuration information includes at least one of:

RS configuration information set, broadcast signal configuration information set, and CORESET configuration information.

For example, in the case where the first information is QCL information, it may be understood as an indication of TRP on (or off) by multiplexing an existing indication field; in this case, it may be understood that the first indication field is a QCL related indication field (e.g., a TCI indication field), and the content indicated in the QCL related indication field has an association with TRP, e.g., TRP 1 when the TCI state indicated in the QCL related indication field is 0 and TRP 2 when the TCI state indicated in the QCL related indication field is 1.

For example, when the first information is a PDCCH transmission location, it may be understood that if the TRP has no dedicated distinguishing information, one PDCCH transmission location is associated with each TRP or each group of TRPs (for example, the transmission location may be CORESET or Search Space (SS)), and the network device transmits the PDCCH corresponding to the specific TRP at the dedicated transmission location of the on (or off) TRP.

It should be noted that, taking the first information as QCL information as an example, in this application case, when the terminal device performs TRP on or off determination based on the first indication domain, the terminal device needs to determine based on the on or off state of the TRP when receiving the first signaling, for example, when the first indication domain indicates the TCI state corresponding to TRP1, if the terminal device receives the first signaling, the terminal device determines that the TRP1 of the first indication domain is closed, and the terminal switches to the configuration information set corresponding to TRP1 on TRP 1; if the terminal equipment receives the first signaling, the TRP1 is in a closed state, the terminal equipment determines that the indication TRP1 of the first indication domain is opened, and the terminal is switched to a configuration information group associated with the TRP1 opened state on the TRP 1.

In this case, the association relationship between the TRP state and the at least one QCL information or the at least one PDCCH transmitting location acquired by the terminal device may be preconfigured, predefined or configured by the network device.

6. Indication of opening and/or closing of at least one or a group of TRPs based on SSSG switch indication information at the first signaling

In this case, the method further includes:

In this case, it can be understood that the first indication domain is an SSSG switching indication domain, that is, an indication of TRP on (or off) by multiplexing an existing SSSG switching indication domain; specifically, two SSSGs may be configured on the TRP dedicated CORESET, corresponding to PDCCH monitoring periods of TRP on (or off) states, respectively; it is also possible to configure only one SSSG on the TRP-specific CORESET, which SSSG corresponds to the PDCCH monitoring period used by the TRP on state, while the PDCCH is not monitored in the TRP off state, and the network device sends this first signaling on the associated location according to the on (or off) TRP.

In this case, the association relationship between the SSSG corresponding to the SSSG switching indication information and the TRP state obtained by the terminal device on at least one CORESET may be preconfigured, predefined or configured by the network device.

7. The first signaling indicates the turn-on and/or turn-off of at least one or a group of TRPs based on PDCCH skip (skip) indication information

In this case, the method further includes:

In this case, it can be understood that the first indication field is a PDCCH skip indication field, that is, an indication of TRP on (or off) is performed by multiplexing an existing PDCCH skip indication field; specifically, a PDCCH skip step number is associated with different TRP to be turned on (or turned off) respectively, and when the terminal device obtains the PDCCH skip step number in the PDCCH skip indication field, it can determine whether to turn on or turn off a certain TRP based on the association relationship between the PDCCH skip step number and the TRP state.

It should be noted that in this application case, when the terminal device determines that the TRP is turned on or off based on the first indication domain, the terminal device needs to be determined based on the on-off state of the TRP when the first signaling is received, for example, when the first indication domain indicates the number of PDCCH skip steps of TRP1, if the terminal device receives the first signaling, the terminal device determines that the first indication domain indicates TRP1 to be turned off, and the terminal does not monitor the PDCCH on one or a group of search spaces corresponding to TRP1 on TRP 1; if the terminal equipment receives the first signaling, the TRP1 is in a closed state, the terminal equipment determines that the indication TRP1 of the first indication domain is opened, and the terminal triggers measurement of TRS resources corresponding to the TRP1 on the TRP 1.

In this case, the association relationship between the at least one PDCCH skip step number acquired by the terminal device and the TRP state may be preconfigured, predefined or configured by the network device.

After receiving the first signaling, the terminal device only needs to analyze and obtain specific information carried in the first signaling, then determine whether to turn on or turn off the TRP based on the association relation between the specific information and the TRP state, and then execute corresponding actions.

For example, in the case that the terminal determines that the first TRP is closed according to the first signaling, performing a first operation;

wherein the first operation includes at least one of:

b11, not monitoring PDCCH on one or a group of search spaces corresponding to the first TRP;

b12, monitoring PDCCH on one or a group of search spaces corresponding to the first TRP in a first period, wherein the period length of the first period is longer than the length of a monitoring period used under the condition that the first TRP is started;

b13, switching to a configuration information group associated with a first TRP off state, the configuration information group comprising at least one of: a reference signal RS configuration information set, a broadcast signal configuration information set, and a control resource set CORESET configuration information.

For example, in the case that the terminal determines that the second TRP is on according to the first signaling, performing a second operation;

wherein the second operation includes at least one of:

BWP, restoring and activating the initial behavior on the BWP;

b22, switching to a configuration information group associated with a second TRP on state, the configuration information group comprising at least one of: RS configuration information set, broadcast signal configuration information set, and CORESET configuration information;

b23, triggering and measuring TRS resources corresponding to the second TRP.

Optionally, in at least one embodiment of the present application, before the sending the first signaling to the terminal, the method further includes:

After receiving the first indication information, in the subsequent process of receiving the first signaling, if the function of retransmitting the first signaling is supported, the terminal device sends HARQ-ACK information to the network device at a HARQ-ACK feedback position according to the receiving condition of the first signaling, where the HARQ-ACK information includes: acknowledgement information or non-acknowledgement information. And under the condition of supporting the function of retransmitting the first signaling, if the network equipment does not receive the acknowledgement information at the HARQ-ACK feedback position, retransmitting the first signaling to the terminal.

For example, when the network device does not support retransmission of the signaling, the network device issues the first signaling once according to the transition of the TRP on (or off) state, and the network device defaults that the terminal device can receive correctly, and updates the corresponding on (or off) behavior according to the TRP state. When the network equipment supports retransmission of the signaling, the network equipment carries/predefines a feedback ACK/NACK position in the signaling, the terminal feeds back the ACK/NACK information at the signaling indication position after correctly receiving the ACK information, and the network equipment continues to send the signaling after not receiving the ACK information until the terminal equipment correctly receives or the first signaling reaches the maximum retransmission times.

Optionally, in at least one embodiment of the present application, the method further includes:

It should be noted that, by this configuration, when the target TRP is turned on, the terminal device can quickly access the target TRP.

Specific applications of the present application are exemplified below.

Application case one, dynamic TRP on (or off) indication based on dormant BWP handoff

The method specifically comprises the following steps:

in step 11, the network device configures N dormant BWP (first dormant BWP, second dormant BWP … nth dormant BWP, N > 1) according to the supportable Multi-TRP number or group number, each dormant BWP corresponds to one or a group of TRP-off and the turned-off TRP-specific CORESET does not configure a Search Space and the turned-off TRP-corresponding RS signal (e.g. channel state information reference signal (Channel StateInformation Reference Signal, CSI-RS), synchronization signal/physical broadcast channel signal block (Synchronization Signal and PBCH block, SSB, which may also be referred to as synchronization signal block), channel sounding reference signal (sounding reference signals, SRS)) and/or broadcast signal long period (or non-period) configuration, while each dormancy is associated with one BWP configuration: 1) The associated BWP is that the current active BWP represents switching configuration information on the current BWP after the signaling is validated; 2) The associated BWP is the other BWP and the signaling is switched to the associated BWP after being validated.

Step 12, when the network device triggers one or a group of Multi-TRP to switch from TRP on state to off state (switch off state to on state), the network issues group common DCI to indicate the information of one or a group of TRP of one (or a group of) UE to turn off (or turn on) in a bit map/code point (bitmap) manner;

Step 13, the UE receiving the signaling triggers the behavior according to the dormant BWP configuration information associated with the TRP closed in the indication: the PDCCH on the sleep BWP-associated CORESET is not detected, and the RS configuration of the sleep BWP-associated RS updates the RS measurement; the signaling indicates the opened TRP, and the UE continuously monitors PDCCH on the TRP exclusive CORESET and measures according to the RS configuration of the original configuration. If the BWP associated with the dormant BWP is the current active BWP indicates that the UE switches configuration information on the current BWP after the signaling is validated, otherwise the UE switches to the associated BWP after the signaling is validated.

If multiple (or multiple groups of) TRPs are indicated to be turned off at the same time, the dormant BWP corresponding to the turned-off TRPs is effective at the same time, i.e. the UE does not monitor the PDCCH on the dedicated CORESET of the turned-off TRPs on the associated dormant BWP at the same time, and the associated RS resources are measured for a long period/non period.

The indication method proposed in this embodiment is described in detail below by taking the design of dynamic TRP switch signaling content under 2 TRP and 4 TRP, respectively, as an example.

1. In case 2 TRPs serve one UE

The network device configures configuration information updated by the terminal after the first dormant BWP and the second dormant BWP are closed and closed corresponding to TRP1 and TRP2 for the UE, and the signaling indication and related configuration information corresponding to TRP closing and opening are as follows:

a) The TRP indication field uses a 2 bit bitmap indication:

[1,0] indicates that the first dormant BWP configuration information is in effect, SS is not configured on corespot index0 of the dormant BWP, TRP1 only configures long-period/non-period RS signals and/or broadcast signals, if the dormant BWP associated BWP is the current active BWP indicating that the signaling is in effect, the UE switches configuration information on the current BWP, otherwise the signaling is in effect, the UE switches to the associated BWP;

[0,1] indicates that the second dormant BWP configuration information is in effect, SS is not configured on coresetpoindex 1 of the BWP, TRP2 only configures long-period/non-period RS signals and/or broadcast signals, if the dormant BWP associated BWP is the current active BWP indicating that the signaling is in effect, the UE switches the configuration information on the current BWP, otherwise the signaling is in effect, the UE switches to the associated BWP;

[0,0] indicates that the original active BWP configuration information is in effect, and original BWP CORESPopoolilndex 0 and 1 maintain the original Search Space configuration, maintain the configuration of RS signals and/or broadcast signals on the original BWP.

b) The TRP indication field employs a 1 bit indication:

[0] instruct TRP1 on/off state switching: the first dormant BWP configuration information is validated, SS is not configured on CORESET corresponding to CORESET pool index0 of the BWP, TRP1 only configures long-period/non-period RS signals and/or broadcast signals, if the dormant BWP associated BWP is the current active BWP, the UE switches the configuration information on the current BWP after the signaling is validated, otherwise, the UE switches to the associated BWP after the signaling is validated;

[1] Indicating TRP2 inter on/off state switching: the second dormant BWP configuration information is validated, SS is not configured on CORESET corresponding to CORESETpool index of the BWP, TRP2 only configures long-period (or non-period) RS signals and/or broadcast signals, if the dormant BWP associated BWP is the current active BWP indicating that the signaling is validated, configuration information is switched on the current BWP by the UE, otherwise the UE is switched to the associated BWP after the signaling is validated;

wherein when the closed TRP is turned on again to serve the UE, this signaling is still issued (TRP indication field is consistent with the bit field setting at TRP off), representing TRP re-opening.

2. In case 4 TRPs serve one UE

a) Single TRP off indication:

the network device configures configuration information updated by the terminal after the four dormancy BWP are closed respectively corresponding to the 4 TRPs for the UE, and specific signaling indication contents are as follows:

1) TRP indication field employing 2-bit codepoint indication

[0,0] indicates TRP1 inter-on/off state switching: the first dormant BWP configuration information is validated, the corresponding CORESET dedicated to TRP1 of the BWP is not configured with SS, TRP1 is configured with long-period/non-period RS signals and/or broadcast signals only, if the BWP associated with the dormant BWP is the current active BWP, the UE switches configuration information on the current BWP after signaling is validated, otherwise, the UE switches to the associated BWP after signaling is validated;

[0,1] indicates TRP2 inter on/off state switching: the second dormant BWP configuration information is validated, the corresponding CORESET dedicated to TRP2 of the BWP is not configured with SS, TRP2 is configured with long-period/non-period RS signals and/or broadcast signals only, if the BWP associated with the dormant BWP is the current active BWP, the UE switches configuration information on the current BWP after signaling is validated, otherwise, the UE switches to the associated BWP after signaling is validated;

similar to the two indications above, [1,0] and [1,1] correspond to TRP3 and 4on/off state switching: the UE switches to/from the third dormant BWP and the fourth dormant BWP, the SS is not configured on CORESET corresponding to the corresponding shutdown TRP, the shutdown TRP only configures long-period (or non-period) RS signals and/or broadcast signals, if the BWP associated with the dormant BWP is the current active BWP, the UE switches configuration information on the current BWP after the signaling is validated, otherwise the UE switches to the associated BWP after the signaling is validated.

Wherein, when the closed TRP is turned on again to provide service to the UE, this signaling is still issued (TRP indication field is consistent with the bit field setting at TRP off), representing TRP re-on.

2) TRP indication field adopts 4-bit bitmap indication

Four bits correspond to four TRP, bit 0-TRP OFF, bit 1-TRP ON, after receiving the signaling, the UE switches to/leaves the corresponding dormant BWP configured ON the network side, SS is not configured ON the CORESET dedicated to the closed TRP ON the BWP, and the closed TRP only configures long-period (or non-period) RS signals and/or broadcast signals. Accordingly, the UE listens for PDCCH, long period/non-period RS signals and/or broadcast signals on CORESET that does not configure SS. If the BWP associated with the dormant BWP is the currently active BWP indicates that the UE switches configuration information on the current BWP after the signaling is validated, otherwise the UE switches to the associated BWP after the signaling is validated

b) TRP group on/off indication:

taking 4 TRP as an example, two TRPs in each group, the network device configures configuration information updated by the terminal after the first dormant BWP and the second dormant BWP are respectively corresponding to TRP group 1 shutdown and TRP group 2 shutdown for the UE, if the dormant BWP associated BWP is the configuration information switched on the current BWP by the UE after the signaling is validated and if the current active BWP is the BWP associated BWP, otherwise, the UE is switched to the associated BWP after the signaling is validated. Signaling indication and corresponding configuration information after TRP on/off state transition are as follows:

1) TRP indication field employing 2-bit codepoint indication

[1,0] indicates TRP group 1 on/off state switching: the first dormant BWP configuration information is validated, SS is not configured on the dedicated CORESET of TRP group 1 of the dormant BWP, and TRP group 1 only configures long-period/non-period RS signals and/or broadcast signals;

[0,1] indicates TRP group 2 on/off state switching: the second dormant BWP configuration information is validated, SS is not configured on the TRP group 2 dedicated CORESET of the BWP, and the TRP group 2 only configures long-period/non-period RS signals and/or broadcast signals.

2) The TRP indication field employs a 1 bit indication:

[0] indicating TRP group 1 on/off inter state switching: the first dormant BWP configuration information is validated, SS is not configured on the dedicated CORESET of TRP group 1 of the BWP, and TRP group 1 only configures long-period/non-period RS signals and/or broadcast signals;

[1] Indicating TRP group 2 inter on/off state switching: the second dormant BWP configuration information is validated, SS is not configured on the TRP group 2 dedicated CORESET of the BWP, and the TRP group 2 only configures long-period/non-period RS signals and/or broadcast signals.

Dynamic TRP on/off indication for application case two based on configuration information group switching

The method specifically comprises the following steps:

in step 21, the network device configures N RS Resource Groups according to the number of Multi-TRP and possible TRP-off, and each RS Resource Group corresponds to one/group of long-period/non-period RS signals (e.g., CSI-RS, SSB, SRS) and/or broadcast signals and/or one (or a group of) TRP-specific CORESET without SS.

Step 22, when the network side triggers a (or a group of) TRP to switch between on/off states, the downlink signaling indicates RS Resource Group ID corresponding to the UE;

step 23, the ue triggers monitoring and not monitors PDCCH on TRP dedicated CORESET after receiving signaling indication, and updates RS and/or broadcast signal resources associated with measurement.

The following describes in detail the indication method proposed in this embodiment, taking the design of dynamically closing TRP signaling content under 2 TRPs as an example, the RRC configuration information is as follows:

RS Resource Group 0: TRP1 and TRP2 configure normal RS signal and/or broadcast signal resource allocation, and SS is normally configured on CORESET corresponding to TRP1 and TRP2 exclusive;

RS Resource Group 1: TRP1 configures long period (or non-period) RS signal and/or broadcast signal resource configuration, TRP2 configures normal RS signal and/or broadcast signal resource configuration, SS is not configured on CORESET corresponding to TRP1 exclusive, SS is configured on CORESET corresponding to TRP2 exclusive;

RS Resource Group 2: TRP1 configures normal RS signal and/or broadcast signal resource configuration, TRP2 configures long period (or non-period) RS signal and/or broadcast signal resource configuration, SS is normally configured on CORESET corresponding to TRP1 exclusive, SS is not configured on CORESET corresponding to TRP2 exclusive;

RS Resource Group 3: TRP1 and TRP2 configure long period/aperiodic RS signal and/or broadcast signal resource allocation, and SS is not configured on CORESET corresponding to TRP1 and TRP 2.

The network device triggers the UE to associate according to the TRP on/off state, RS Resource GroupID that the lower signaling indication takes effect: 00 corresponds to RS Resource Group; 01 corresponds to RS resource group 1;10 corresponds to RS Resource Group; 11 corresponds to RS Resource Group.

The dynamic TRP on/off indication of the TRP association-based configuration information group switching in the application case III specifically comprises the following processes:

step 31, the network device associates two Resource groups for each (or each group of) TRP;

RS Resource group 0: the corresponding RS signal (e.g., CSI-RS, SSB, SRS) and/or broadcast signal normal measurement with the TRP (or set of TRPs) in the on state, the TRP-specific CORESET normally configures the Search Space;

RS Resource group 1: the corresponding RS signal (e.g., CSI-RS, SSB, SRS) and/or broadcast signal long period/aperiodic measurements with the TRP (or set of TRP) in the off state, the TRP-specific CORESET is not configured with a Search Space.

In step 32, each (or each group of) TRP in the signaling corresponds to a 1-bit indication Resource group ID, when the network device triggers a certain (or a group of) TRP to perform an on/off state transition, the lower signaling indicates that the corresponding TRP switches between associated Resource group 0 and Resource group 1, and bit setting 0: resource group 0 takes effect; bit setting 1: resource group 1 takes effect;

step 33, when the network device triggers the state switching between on/off of one or more TRP, the UE sends down a Resource Group ID corresponding to the signaling indication UE, and after receiving the signaling indication, the UE monitors and does not monitor the PDCCH on the dedicated core for TRP, and measures the effective RS signal and/or broadcast signal Resource.

The dynamic TRP on/off indication of the switching of the configuration information group based on TCI association in the application case IV specifically comprises the following processes:

In step 41, the network device associates two Resource groups for each TCI state corresponding to each TRP, where Resource group 0 represents a corresponding RS conventional measurement with the TRP in the ON state, and the TRP dedicated CORESET normally configures the Search Space. Resource group 1 represents a corresponding RS (e.g., CSI-RS, SSB, SRS) long period (or aperiodic) measurement with TRP in the off state, with TRP-specific CORESET not configured with Search Space.

Step 42, the TCI indication field for each TRP in the signaling associates 1 bit Resource group indication field: an indication Resource group ID; when the network device triggers a certain TRP/group to perform on/off state transition, the downlink signaling indicates that the Resource group indication domain associated with the corresponding TCI state is switched between Resource group 0 and Resource group 1, and the bit is set to 0: resource group 0; bit setting 1: resource group 1;

in step 43, the terminal detects the signaling, and triggers the associated action according to the TCI indication and Resource group ID, for example, the signaling indicates TCI 0, i.e. Resource group 0, the ue is not listening to the PDCCH on the TRP dedicated CORESET corresponding to TCI 0, and configures the measurement reference signal according to Resource group 0.

Application case five, dynamic TRP on/off indication based on transmit location and configuration information group switching

The method specifically comprises the following steps:

step 51, the network side configures two or more Resource groups for each (or each group of) TRP associated CORESET/coresetpoinolindex (if the network side is not configured with TRP-specific CORESET, one or a group of TRPs are associated according to the existing CORESET/Search Space);

step 52, setting a Resource group indication domain in the group Common signaling, when the network device triggers one (or a group of) TRPs to perform on/off state transition, issuing the signaling on the CORESET/Search Space associated with the TRPs, wherein the Resource group indication domain in the signaling indicates RS Resource group ID corresponding to the TRP state;

step 53, the terminal detects the signal on the correlated core/Search Space associated with the TRP, measures the relevant reference signal according to RS Resource group ID in the signal, and determines whether to monitor the PDCCH on the CRORSET dedicated to the TRP/group according to the TRP status before receiving the signal.

Application case six, dynamic TRP on/off indication based on PDCCH listening adaptation and configuration information group switching

Similar to application five, the network device associates two SSSGs (SSSG 0-regular listening; SSSG 1-long listening period/non-listening) on the CORESET associated with each (or each group) of TRPs, each SSSG associates one Resource group (SSSG 0-associated CSI-Resource group 0-regular reference signal (e.g., CSI-RS, SSB, SRS) and/or broadcast signal configuration, SSSG 1-associated Resource group 1-long period/non-periodic reference signal and/or broadcast signal configuration), when the network device triggers one (or a group of) of TRPs to make an on/off inter-state transition, signaling down DCI format 2_0 on the TRP associated CORESET, switches between SSSG0 and SSSG1 through a searsspacesswitch trigger indication field, and implicitly instructs the TRP on/off state transition, while triggering the UE to perform a Resource switch.

Application case seven TRP on/off indication based on group common RRC signaling

Step 71, the network device pre-configures N configuration information sets according to the supportable Multi-TRP number or sets and possible TRP (set) switch conditions, where the information sets include at least one of the following configurations:

RS Resource Group, which contains configuration information such as time-frequency resources and/or period and/or terminal reporting measurement quantity of a periodic/aperiodic RS signal (e.g., CSI-RS, SSB, SRS) and/or broadcast signal associated with one/group of TRP;

one/group TRP exclusive CORESET is not configured with SS;

TRP identification information, such as TRP/TRP group ID, CORESETPoolindex;

BWP ID；

CC ID。

step 72, when the network device triggers a state switch between on/off of one or a group of TRPs, issuing a group Common RRC signaling bearer indication TRP switch information and/or a pre-configuration information group indication information indication and triggering at least one group of pre-configuration information groups to take effect; wherein,

TRP on/off information indicated based on codepoint and/or bitmap;

for example, bitmap indicates: 0001-TRP (group) 0-2 off, TRP (group) 3 on;

codepoint indicates: 00-TRP (group) 0 is off/on.

Information indicating that the pre-configuration information group takes effect based on the codepoint and/or bitmap;

For example, bitmap indicates: 0001-failure of pre-configuration information set 0-2 (pre-defined association with TRP: corresponding TRP (set) 0-2 off), validation of pre-configuration information set 3 (TRP (set) 3 on);

wherein, the group common RRC signaling can be carried by SIB message and/or PBCH and/or PDSCH and/or group common PDSCH scheduled by group common PDCCH; the PBCH carries 2 TRP switch information as an example:

2.1 predefining 4 groups of configuration resource information groups, group 0-2 TRP full open RS/CORESET configuration information;

RS/CORESET configuration information with Group 1-TRP1 on TRP2 off; RS/CORESET configuration information with Group 2-TRP1 off TRP2 on; all of Group 3-2 TRPs close RS/CORESESET configuration information;

2.2 adding TRP switch/configuration information group indication domain in MIB message, defining the indication domain length as 2 bits, and the base station indicating corresponding value in the indication domain in MIB message according to the change of TRP switch state, such as:

00-TRP1 and 2 are all on, and the pre-configuration information Group 0 is in effect;

01-TRP1 on TRP2 off, pre-configuration information Group 1 is in effect;

10-TRP2 on TRP1 off, pre-configuration information Group 2 is in effect;

11-TRP1 and 2 are all off, and the Group of pre-configuration information Group 3 is active;

2.3 the terminal detects the corresponding information of the TRP switch indicated by the TRP switch/configuration information group indication domain and/or configuration information group in the receiving of the MIB message, and updates the corresponding behavior.

Optionally, this signaling may be predefined whether the ACK/NACK is fed back 73. If the predefined configuration requires the terminal to feed back the ACK/NACK, the UE feeds back the ACK/NACK information according to the received signaling indication. And updating the RS/PDCCH to send according to the pre-configuration information associated with the signaling only after the terminal feeds back the ACK information and the base station successfully receives the ACK information of the terminal. Accordingly, the terminal triggers the pre-configuration information set of the signaling indication to take effect after feeding back the ACK, namely does not monitor the PDCCH on the dedicated CORESET of the closing/monitoring opening TRP, and updates the RS and/or broadcast signal resources associated with measurement. If the ACK/NACK is predefined not to be fed back, the terminal immediately updates the behavior after successfully receiving the signaling, and correspondingly, the base station also updates the RS/PDCCH to send after issuing the signaling.

It should be noted that, in the PDCCH signaling dynamically indicating that TRP is turned on or off, in the Multi-TRP transmission, when only one or a part of TRP service can ensure reliability, and in the case of throughput transmission, the rest TRP is turned off to save energy consumption of the network device, and simultaneously, the signaling is issued to instruct the UE to trigger the terminal energy saving behavior: the PDCCH and reference signal (e.g., SSB, CSI-RS, etc.) measurement behavior update on the partial Search Space is not detected (or with a long listening period), and the energy consumption overhead on the network side and the terminal side can be saved at the same time. When the TRP needing to be closed starts the guaranteed service, the downlink instruction restores the UE behavior under the original Multi-TRP transmission, and high-reliability transmission is guaranteed. And when the high-reliability and high-throughput transmission of the system are ensured, the energy consumption expenditure of the network side and the terminal is reduced.

In summary, the following beneficial effects can be achieved by the embodiment of the application:

1. in the existing Multi-TRP transmission, if the CORESET for distinguishing TRPs is configured at a higher layer, the UE always monitors PDCCH corresponding to the TRP on the configured CORESET, and if the network equipment closes some TRPs and signals down to instruct the UE not to detect the Search Space corresponding to the closed TRP, unnecessary blind detection power consumption of the terminal can be saved.

2. In the DCP mechanism, the DCP wakes up the UE to monitor all the Search spaces on the current BWP, and if the UE supports Multi-TRP transmission, the UE monitors all the Search spaces corresponding to the TRP. However, in addition to a few scenarios, the UE can select an optimal TRP/link to ensure reliable transmission, and there is additional power consumption of the base station TRP and power consumption overhead of the UE to detect the PDCCH at the corresponding CORESET positions of these TRPs.

3. The turned-off TRP may not transmit (or transmit with a long listening period) a reference signal (e.g., SSB, CSI-RS); the terminal cannot distinguish the CSI-RS resource allocation of Multi-TRP, when the network equipment closes a part of TRPs, the TRPs can only maintain the CSI-RS with long period (or non-period), and the UE can update the CSI-RS measurement behavior on the closed TRP by carrying the reference signal configuration information associated with the closed TRP in the first signaling adopted by the method, so that the power consumption of the UE for measuring the CSI-RS is further reduced.
