technical field

The present application belongs to the technical field of communications, and in particular relates to a method, device and terminal for determining power control PC parameters.

Background technique

The significance of power control (PC) in the current technology includes: maintaining power (adjusting power according to the distance between the terminal and the base station to ensure that the power of the signal reaching the base station is close); improving performance (dynamically adjusting power according to channel changes to achieve accurate Fast power adjustment); reduce interference (reduce adjacent channel power leakage, reduce interference between users and cells, and extend battery life).

The power control is divided as follows:

Downlink power control mainly depends on the configuration and implementation of the network side;

Uplink power control mainly includes: PC for Physical Uplink Shared Channel (PUSCH), PC for Physical Uplink Control Channel (PUCCH), PC for Sounding Reference Signal (SRS), PC of Physical Random Access Channel (PRACH);

It also includes: Power Headroom Report (PHR), which is mainly to assist base station scheduling; power scaling (Power scaling/sharing), whose main purpose is to share power and ensure higher priority cell/channel transmission.

On the one hand, 5G introduces a new unified Transmission Configuration Indicator (TCI) framework, which can be called the unified TCI framework (unified TCI framework), that is, the network uses the Media Access Control layer control unit (Media Access Control Control Element, MAC CE) and/or downlink control information (Downlink Control Information, DCI) indicates that the same beam (beam) can be used for multiple channel transmission, and this beam can also be called a common beam (common beam). The unified TCI framework includes two modes of joint TCI (joint TCI) and independent TCI (separate TCI), which are configured by radio resource control (Radio Resource Control, RRC) signaling of the network. Wherein, the combined TCI state indication specifically includes: indicating that a certain TCI state is used for uplink transmission and downlink transmission at the same time; the independent TCI state indication specifically includes: indicating that a certain TCI state is used for uplink transmission or downlink transmission.

On the other hand, 5G introduces multi-transmission receiving node (multi-TRP, which can be referred to as MTRP) transmission, and the control signaling is divided into two cases: single DCI scheduling and multi-DCI scheduling:

Multi-DCI (multi-DCI, may be referred to as mDCI) scheduling: each transmission and reception point (Transmission and Reception Point, TRP) sends its own PDCCH, and each PDCCH schedules its own PDSCH. At this time, the network is a user equipment (User Equipment, Multiple control resource sets (Control resource set, CORESET) configured by UE) are associated with different RRC parameter CORESET pool indexes (CORESETPoolIndex), corresponding to different TRPs;

Single DCI (single DCI, which can be referred to as sDCI for short) scheduling: A PDCCH is sent by a TRP to schedule a PDSCH. At this time, multiple CORESETs configured by the network for the UE cannot be associated with different CORESETPoolIndex. In this case, MAC CE activates up to 8 code points (codepoint), at least one of which corresponds to two TCI states (TCI state). When the codepoint indicated by the TCI field (TCI field) in a DCI corresponds to two TCI states and indicates that one TCI state contains "QCL-TypeD", it means that the scheduled PDSCH comes from two TRPs.

However, in the unified TCI framework, it is only applied to a single TRP scenario at present, and there is no solution for how to determine the power control parameters of the uplink channel when the unified TCI framework is applied in a multi-TRP scenario.

The method for determining the power control PC parameter provided by the embodiment of the present application will be described in detail below through some embodiments and application scenarios with reference to the accompanying drawings.

Please refer to FIG. 2. FIG. 2 is a flowchart of steps of a method for determining a power control PC parameter provided in an embodiment of the present application. The method for determining a PC parameter includes:

Step 201, the terminal receives the common beam information indicated by the network side device, the common beam information includes: N joint transmission configuration indication TCI status information, or N independent TCI status information, N is an integer greater than or equal to 1;

In this step, the N pieces of joint TCI state information can be understood as N pieces of TCI state information used for uplink transmission and downlink transmission at the same time. N pieces of independent TCI state information can be understood as N pieces of TCI state information for uplink transmission, or N pieces of TCI state information for downlink transmission, or N1 pieces of TCI state information for uplink transmission and N2 pieces of TCI state information for downlink transmission The transmitted TCI status information, and N1+N2 is equal to N. It should be noted that the "TCI status information" mentioned in the embodiment of this application may be any one of the above-mentioned N joint TCI status information, or any one of the above-mentioned N independent TCI status information, which will not be described in detail here. limited.

Step 202, in the case that the TCI status information is associated with or includes PC parameters, the terminal determines that the PC parameters of the uplink channel to which the TCI status information is applied are the PC parameters associated with or included in the TCI status information; and/or In a case where the TCI state information is not associated with or does not contain PC parameters, the terminal determines PC parameters of an uplink channel to which the TCI state information is applied according to target parameters.

It should be noted that the "PC parameter" mentioned in the embodiment of the present application in "the case where the TCI state information is associated with or contains a PC parameter" and "the case where the TCI state information is not associated or contains a PC parameter" can specifically be one A set of PC parameters, or a part of PC parameters in a set of PC parameters. Wherein, a set of PC parameters includes: a path loss estimation reference signal and/or a parameter set (setting), and the parameter set includes: an open-loop receiving end power target value P0, a partial path loss compensation factor α, and a closed-loop power control index CLI at least one of the .

If the PC parameters are part of the PC parameters in a set of PC parameters, for example, the TCI status information is associated with or includes the first part of the PC parameters in a set of PC parameters (the TCI status information is not associated or does not include the In the case of the second part of the PC parameter of the set of PC parameters), the first part of the PC parameter of the uplink channel to which the TCI state information is applied is the first part of the PC parameter associated with or contained in the TCI state information; the uplink channel to which the TCI state information is applied The second part of PC parameters is determined by the terminal according to the target parameters.

Wherein, the target parameters include at least one of the following:

PC parameters included in the configuration information of the uplink channel;

PC parameters associated with the uplink channel;

Default PC parameters for network configuration;

The default PC parameters agreed in the protocol;

PC parameters included in the spatial relationship information configured on the frequency band or carrier where the uplink channel is located or on the bandwidth part (Bandwidth Part, BWP);

It should be noted that, when N is greater than 1, the N pieces of TCI state information may all be associated with or contain PC parameters, or none of the N pieces of TCI state information may be associated with or contain no PC parameters, or, the N pieces of TCI state information Part of the TCI state information is associated with or contains PC parameters, and part of the TCI state information is not associated with or does not contain PC parameters.

Optionally, when N is greater than 1, N may be understood as the number of TRPs, for example, N is equal to 2, and the plurality of TCI state information are TCI state information corresponding to each TRP. When N is equal to 1, the one piece of TCI state information is the TCI state information of a certain TRP among the multiple TRPs, or the common TCI state information of all TRPs.

It should be noted that, in the multi-TRP scenario applied in the embodiment of this application, for the case where N is equal to 1, there are the following two situations:

Case 1, in the case of multiple downlink control information (Downlink Control Information, DCI) scheduling, the terminal can determine that it is in the multiple DCI mode of the multiple TRP scenario according to the network configuration of multiple different TRP ID information (such as the RRC parameter CORESETPoolIndex). In the scenario, the terminal can also determine that the scheduled channel corresponds to a certain TRP according to the received DCI. Specifically, the DCI will indicate 1 TCI status information, and the 1 TCI status information can be used to determine the scheduled channel. It corresponds to a certain TRP among the multiple TRPs (the uplink channel to which the TCI state information is applied can be understood as the uplink channel of the TRP corresponding to the TCI state information).

Case 2, in the case of single DCI scheduling, the terminal can indirectly determine the location according to the configuration information of the network. In a multi-TRP scenario, for example, according to the number of TCI states corresponding to each code point in the code points activated by the MAC CE, in this scenario, the terminal determines that the scheduled channel corresponds to the TCI state according to the received DCI indicated by the code point. For one or more TRPs, when the code point indicated by the DCI corresponds to one TCI state, the one TCI state can be used to determine that the DCI-scheduled uplink channel applies the one TCI state information and corresponds to one of the multiple TRPs a TRP.

As an optional embodiment, the uplink channel mentioned in the embodiment of this application includes: a physical uplink control channel (Physical Uplink Control Channel, PUCCH) and/or a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH). PUSCH and PUCCH can be at least one of the following:

Preset PDCCH scheduling or associated PUSCH and PUCCH

UE-specific PUSCH or PUCCH;

Dynamically scheduled PUSCH;

Configure authorized PUSCH (Configured grant PUSCH);

Among them, the preset physical downlink control channel (Physical Downlink Control Channel, PDCCH) can be: all PDCCHs, or, the PDCCH on the UE-dedicated control resource set (Control Resource Set, CORESET), or, only associated with the user-specific search space (UE -Specific Search Space, PDCCH on CORESET of USS), or, PDCCH on CORESET associated with USS and common search space CSS, or, PDCCH on CORESET other than CORESET#0.

In at least one embodiment of the present application, the PC parameters of the uplink channel may also be referred to as a set of PC parameters of the uplink channel, wherein the set of PC parameters includes: a path loss estimation reference signal and/or a parameter set (setting), so The above parameter set includes: at least one item of open-loop receiver power target value P0, partial path loss compensation factor α, and closed-loop power control index (Close Loop Index, CLI).

Optionally, in the embodiment of the present application, if the TCI status information indicated by the network is associated with or contains PC parameters, then the PUCCH power control (such as corresponding to a certain TRP ID) corresponding to the TCI status information is associated with the TCI status information. or included PC parameters; or, the PUSCH power control corresponding to the TCI state information (such as corresponding to a certain TRP ID), uses the PC parameters associated or included in the TCI state information.

As an optional embodiment, when the TCI state information is associated with or contains PC parameters Next, the method also includes:

If spatial relation information (spatial relation info) is configured on the frequency band or carrier or BWP where the uplink channel is located, and the spatial relation information includes PC parameters, the terminal ignores the PC parameters included in the spatial relation information; It is called the PC parameter associated with or contained in the TCI state information that the terminal preferentially uses.

For example, PUCCH spatial relationship information is configured on the frequency band or carrier or BWP configured with unified TCI. The PUCCH spatial relationship information includes PC parameters, and the terminal preferentially uses the PC parameters associated with or contained in the TCI status information indicated by the network.

As another optional embodiment, in the case where the TCI state information is associated with or contains PC parameters, the method further includes:

When the uplink channel to which the TCI state information is applied is located in the frequency range FR1, the terminal ignores the quasi-co-location type D reference signal (QCL-TypeD RS) in the TCI state information, or, the TCI state Quasi-co-located Type D reference signals (QCL-TypeD RS) are not included in the information. That is to say, the uplink channel of the low frequency band usually does not need to use the beam information similar to the high frequency band, so the QCL-TypeD RS used to determine the beam information in the TCI status information is useless and can be ignored.

For example, for the PUCCH of frequency range 1 (Frequency Range 1, FR1), the terminal ignores the QCL-TypeD RS in the TCI status information.

For another example, for the PUSCH of FRI, the terminal ignores the QCL-TypeD RS in the TCI status information, or the TCI status information does not include the QCL-TypeD RS.

In at least one embodiment of the present application, in the case where the target parameter is a PC parameter included in the configuration information of the uplink channel, the terminal determines, according to the target parameter, the Before the PC parameter, the method also includes:

The terminal receives configuration information of the uplink channel, where the configuration information of the uplink channel includes at least one set of PC parameters. For example, the configuration information of the uplink channel includes: configuration information of the PUCCH, and/or configuration information of the PUSCH, which are not specifically limited here.

Correspondingly, according to the target parameter, the terminal determines the PC parameter of the uplink channel to which the TCI status information is applied, including:

In the case that the configuration information of the uplink channel includes a set of PC parameters, the terminal determines that it should Using the PC parameters of the uplink channel of the TCI state information as the set of PC parameters;

or,

In the case that the configuration information of the uplink channel includes two or more sets of PC parameters, the terminal determines the PC parameters of the uplink channel to which the TCI status information is applied according to the first correspondence: wherein, the first correspondence The relationship includes at least one of the following: the correspondence between the order of the PC parameters and the identification of the TCI state information, the correspondence between the order of the PC parameters and the identification of the TRP corresponding to the uplink channel, the position of the PC parameters and the identification of the TCI state information Corresponding relationship, corresponding relationship between the position of the PC parameter and the TRP identifier corresponding to the uplink channel, the corresponding relationship between the identifier of the PC parameter and the identifier of the TCI state information, and the corresponding relationship between the identifier of the PC parameter and the TRP identifier corresponding to the uplink channel .

For example, when N is equal to 1, the configuration information of the uplink channel includes 2 sets of PC parameters, and the terminal uses the set of PC parameters corresponding to the TCI status information or the preset TRP. The corresponding relationship can be based on the corresponding relationship between the order/position/ID of the PC parameters and the TCI status ID or TRP ID. The preset TRP ID is the TRP ID associated with the PUCCH or PUSCH, or the TRP ID corresponding to the PDCCH that schedules or triggers the PUCCH. Wherein, the TRP corresponding to the uplink channel can be understood as: the TRP associated with the uplink channel; it can also be understood as: the TRP corresponding to the downlink control channel that schedules or triggers the uplink channel. For multiple DCI scenarios, the TRP can be represented by the RRC parameter CORESETPoolIndex. For a single DCI scenario, since the network may not configure the RRC parameter CORESETPoolIndex, the channel group can be used to indirectly represent the TRP.

For example, if the configuration information of PUCCH or PUSCH includes a set of PC parameters, then the PC parameters of PUCCH or PUSCH to which the TCI status information is applied are a set of PC parameters in the configuration information.

For another example, if the configuration information of PUCCH or PUSCH includes two or more sets of PC parameters, then the PC parameters of PUCCH or PUSCH to which the TCI state information is applied are: a set of PC parameters corresponding to the TCI state information.

For another example, when multiple TCI state information is not associated or does not contain PC parameters, and the configuration information includes multiple sets of PC parameters, one TCI state information corresponds to a set of PC parameters in the configuration information; or, in multiple If none of the TCI status information is associated or contains PC parameters, and the configuration information includes a set of PC parameters, multiple TCI status information corresponds to a set of PCs in the configuration information. parameters; or, in the case that a TCI state information is not associated or does not contain PC parameters, and the configuration information includes multiple sets of PC parameters, the TCI state information corresponds to a set of default PC parameters in the configuration information, and the default PC parameters The position or sequence or ID can be configured by the network, and can also be pre-determined.

Optionally, when the configuration information of PUCCH or PUSCH includes two or more sets of PC parameters, only the CLI is different among the two or more sets of PC parameters.

In at least one embodiment of the present application, when the target parameter is a PC parameter associated with an uplink channel, before the terminal determines the PC parameter of the uplink channel to which the TCI state information is applied according to the target parameter, the Methods also include:

The terminal receives first signaling, where the first signaling is used to configure or indicate at least one set of PC parameters associated with the uplink channel. For example, the first signaling is RRC signaling or MAC CE signaling.

Optionally, the PC parameter associated with the uplink channel may also be referred to as: the PC parameter associated with the uplink channel resource.

For example, the network uses RRC signaling to configure at least one set of PC parameters associated with PUCCH resources; or, the network uses MAC CE to indicate at least one set of PC parameters associated with PUCCH resources.

For example, when N is equal to 1, the network uses the MAC CE to indicate that the PUCCH resource is associated with two sets of PC parameters, and the terminal uses a set of PC parameters corresponding to the TCI status information or the preset TRP. The corresponding relationship can be based on the corresponding relationship between the order/position/ID of the PC parameters and the TCI status ID or TRP ID. The preset TRP ID is the TRP ID associated with the PUCCH or PUSCH, or the TRP ID corresponding to the PDCCH that schedules or triggers the PUCCH.

As an optional embodiment, before the terminal receives the first signaling, the method further includes:

The terminal receives second signaling, the second signaling is used to configure a first PC parameter set for the uplink channel, and the first PC parameter set includes multiple sets of PC parameters; for example, the second signaling is RRC signaling.

Wherein, the first signaling is used to indicate that at least one set of PC parameters in the first PC parameter set is associated with the uplink channel.

For example, the network uses RRC signaling to configure a first PC parameter set for PUCCH, and the network uses MAC CE to instruct PUCCH resources to associate at least one set of PC parameters in the first PC parameter set for power control of PUCCH.

Correspondingly, the terminal determines the uplink signal to which the TCI state information is applied according to the target parameter. Tao's PC parameters include:

When the first signaling configures or indicates a set of PC parameters associated with the uplink channel, the terminal determines that the PC parameters of the uplink channel to which the TCI status information is applied are the set of PC parameters;

or,

When the first signaling configures or indicates two or more sets of PC parameters associated with the uplink channel, the terminal determines the PC parameters of the uplink channel to which the TCI state information is applied according to the first correspondence : Wherein, the first corresponding relationship includes at least one of the following: the corresponding relationship between the order of PC parameters and the identification of TCI state information, the corresponding relationship between the order of PC parameters and the TRP identification corresponding to the uplink channel, and the corresponding relationship between the order of PC parameters and the TRP identification corresponding to the uplink channel. The corresponding relationship between the location and the identifier of the TCI state information, the corresponding relationship between the location of the PC parameter and the TRP identifier corresponding to the uplink channel, the corresponding relationship between the identifier of the PC parameter and the identifier of the TCI status information, and the relationship between the identifier of the PC parameter and the uplink channel The corresponding relationship of the TRP identifier corresponding to the channel.

Wherein, the TRP corresponding to the uplink channel can be understood as: the TRP associated with the uplink channel; it can also be understood as: the TRP corresponding to the downlink control channel that schedules or triggers the uplink channel.

For example, if the first signaling configures or indicates a set of PC parameters, then the PC parameters of the PUCCH or PUSCH to which the TCI status information is applied are the set of PC parameters.

For another example, if the first signaling includes two or more sets of PC parameters, then the PC parameters of the PUCCH or PUSCH to which the TCI status information is applied are: a set of PC parameters corresponding to the TCI status information.
