Patent Application
20240406888
This application belongs to the field of communication technologies, and specifically, to a method and an apparatus for determining a power control PC parameter, and a terminal.
A meaning of power control (PC) in a current technology includes: maintaining a power (where the power is adjusted based on a distance between a terminal and a base station, to ensure that powers of signals arriving at the base station are similar); improving performance (where a power is adjusted dynamically based on a channel change, to accurately and quickly adjust the power); and reducing interference (where power leakage of an adjacent channel is reduced, inter-user and inter-cell interference is reduced, and battery life is prolonged).
Division of the power control is as follows:
The power control further includes power headroom report (PHR), mainly for assisting the base station in scheduling; and power scaling (Power sharing), mainly for sharing a power and ensuring transmission of a cell/channel with a high priority.
On one hand, a new unified transmission configuration indicator (TCI) framework is introduced in a 5th generation (5G) communication system, and may be referred to as a unified TCI framework. To be specific, a same beam indicated by a network by using a media access control control element (MAC CE) and/or downlink control information (DCI) may be used for transmission of a plurality of channels. The beam may also be referred to as a common beam. The unified TCI framework includes two modes: a joint TCI mode and a separate TCI mode, and is configured by using radio resource control (RRC) signaling of the network. A joint TCI state indication specifically includes indicating that a TCI state is used for both uplink transmission and downlink transmission; and a separate TCI state indication specifically includes indicating that a TCI state is used for uplink transmission or downlink transmission.
On the other hand, multi-transmission and reception point (multi-TRP, which may be referred to as MTRP for short) transmission is introduced in 5G. Signaling control is classified into two cases: single-DCI scheduling and multi-DCI scheduling.
Multi-DCI (which may be referred to as mDCI for short) scheduling: Each transmission and reception point (TRP) transmits a respective PDCCH, and each PDCCH schedules a respective physical downlink shared channel (PDSCH). In this case, a plurality of control resource sets (CORESETs) configured by a network for user equipment (UE) are associated with different CORESET pool indexes (CORESETPoolindexes) of RRC parameters, and correspond to different TRPs.
Single-DCI (which may be referred to as sDCI for short) scheduling: A PDCCH is transmitted by a TRP to schedule a PDSCH. In this case, a plurality of CORESETs configured by a network for UE cannot be associated with different CORESETPoolIndexes. In this case, the MAC CE activates a maximum of 8 codepoints, where at least one codepoint corresponds to two TCI states. When a codepoint indicated by a TCI field in DCI corresponds to two TCI states and indicates that a TCI state includes “QCL-TypeD”, it means that a scheduled PDSCH is from two TRPs.
However, the unified TCI framework is currently applied to only a single-TRP scenario, and there is no solution to how to determine an uplink power control parameter when the unified TCI framework is applied to a multi-TRP scenario.

The technical solutions in embodiments of this application are clearly described below with reference to the accompanying drawings in embodiments of this application. It is clear that the described embodiments are some rather than all of embodiments of this application. All other embodiments obtained by a person skilled in the art based on embodiments of this application fall within the protection scope of this application.
In this specification and claims of this application, the terms “first”, “second”, and so on are intended to distinguish similar objects but do not indicate a specific order or sequence. It should be understood that the terms used in this way are exchangeable in a proper case, so that embodiments of this application can be implemented in sequences other than those illustrated or described herein. The objects distinguished by “first” and “second” are usually a class, and a quantity of the objects is not limited. For example, a first object may be one or a plurality of objects. In addition, “and/or” in the specification and claims means at least one of connected objects, and a character “/” usually means that a preceding and succeeding related objects are in an “or” relationship.
It is worth noting that technologies described in embodiments of this application are not limited to a long term evolution (LTE)/LTE-Advanced (LTE-A) system, and may alternatively be applied to another wireless communication system, such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), single-carrier frequency division multiple access (SC-FDMA), and another system. The terms “system” and “network” in embodiments of this application are often used interchangeably, and the described technologies may be used in the foregoing systems and wireless technologies, or may be used in other systems and wireless technologies. A new radio (NR) system is described in the following descriptions as an example, and NR terms are used in most of the following descriptions, but the technologies may alternatively be applied to an application, such as a 6th generation (6G) communication system, other than an NR system application.
A method for determining a power control PC parameter according to embodiments of this application is described in detail below by using some embodiments and application scenarios thereof with reference to the accompanying drawings.
In this step, the M pieces of joint TCI state information may be understood as M pieces of TCI state information that are simultaneously for uplink transmission and downlink transmission. The M pieces of separate TCI state information may be understood as M pieces of TCI state information for uplink transmission, M pieces of TCI state information for downlink transmission, or Ml pieces of TCI state information for uplink transmission and M2 pieces of TCI state information for downlink transmission, where M1+M2 is equal to M. It should be noted that the “TCI state information” mentioned in this embodiment of this application may be any one of the foregoing M pieces of joint TCI state information or any one of the foregoing M pieces of separate TCI state information. This is not specifically limited herein.
It should be noted that the “PC parameter” in the “when the TCI state information is associated with or includes a PC parameter” and the “when the TCI state information is not associated with or does not include a PC parameter” mentioned in this embodiment of this application may be specifically a set of PC parameters or a part of PC parameters in a set of PC parameters. The set of PC parameters includes a path loss reference signa and/or a parameter setting. The parameter setting includes at least one of a target power value P0 of an open loop receive end, a partial path loss compensation factor α, and a close loop power control index (Close Loop Index, CLI).
If the PC parameter is a part of PC parameters in a set of PC parameters, for example, when the TCI state information is associated with or includes a first part of PC parameters in the set of PC parameters (where the TCI state information is not associated with or does not include a second part of PC parameters in the set of PC parameters), a first part of PC parameters of the SRS resource to which the TCI state information is applied are the first part of the PC parameters associated with or included in the TCI state information, and a second part of PC parameters of the SRS resource to which the TCI state information is applied are determined based on the configuration information of the SRS resource set.
It should be noted that, when M is greater than 1, all of the M pieces of TCI state information may be associated with or include the PC parameter. Alternatively, none of the M pieces of TCI state information is associated with or includes the PC parameter. Alternatively, a part of the M pieces of TCI state information are associated with or include the PC parameter, and a part of the M pieces of TCI state information are not associated with or do not include the PC parameter.
Optionally, when M is greater than 1, M may be understood as a quantity of TRPs. For example, when M is equal to 2, the plurality of pieces of TCI state information are TCI state information respectively corresponding to TRPs. When M is equal to 1, the TCI state information is TCI state information of a TRP in a plurality of TRPs or TCI state information common to all TRPs.
It should be noted that, in a multi-TRP scenario to which this embodiment of this application is applied, when N is equal to 1, there are the following two cases:
Case 1: In a multi-DCI scheduling case, the terminal may determine, based on that a network configures a plurality of pieces of different TRP identity (ID) information (for example, CORESETPoolIndexes of RRC parameters), that the terminal is in a multi-DCI mode in the multi-TRP scenario. In this scenario, the terminal may further determine, based on received DCI, that a scheduled channel corresponds to a TRP. Specifically, one piece of TCI state information is indicated in the DCI. The TCI state information may be for determining that the scheduled channel corresponds to a TRP in a plurality of TRPs (where an uplink channel to which the TCI state information is applied may be understood as an uplink channel of the TRP corresponding to the TCI state information).
Case 2: In a single-DCI scheduling case, the terminal may indirectly determine, based on configuration information of a network, for example, based on a quantity of TCI states corresponding to each codepoint in codepoints activated by using a MAC CE, that the terminal is in the multi-TRP scenario. In this scenario, the terminal determines, based on a TCI state corresponding to a codepoint indicated by received DCI, that a scheduled channel corresponds to one or more TRPs. When the codepoint indicated by the DCI corresponds to one TCI state, the TCI state may be for determining that an uplink channel scheduled by using the DCI applies the TCI state information and corresponds to a TRP in a plurality of TRPs.
In an optional embodiment, the PC parameter includes a path loss reference signa (PLRS) and/or a parameter setting. The parameter setting includes at least one of a target power value P0 of an open loop receive end, a partial path loss compensation factor α, and a close loop power control index CLI.
In an optional embodiment, the network may configure an SRS resource set, or the network may configure a plurality of SRS resource sets.
In at least one embodiment of this application, step 202 in which when the TCI state information is associated with or includes the PC parameter, the terminal determines, based on the PC parameter associated with or included in the TCI state information, the PC parameter of the SRS resource to which the TCI state information is applied includes:
When the network configures a first SRS resource set, the terminal determines the PC parameter of the SRS resource that is in the first SRS resource set and to which the TCI state information is applied as:
For example, the first SRS resource set includes K SRS resources, where K is an integer greater than or equal to 1. Optionally, the method is applied to a multi-DCI scenario with a plurality of TRPs.
In an optional embodiment, when K is equal to 1, in other words, when the first SRS resource set includes one SRS resource, the terminal determines that the SRS resource uses the preset TCI state information, and a PC parameter of the SRS resource is the PC parameter associated with or included in the preset TCI state information. The preset TCI state information is any one of the following:
Optionally, the first identification information includes at least one of the following:
In another optional embodiment, when K is greater than or equal to 2 (for example, K is equal to 2), in other words, when the first SRS resource set includes a plurality of SRS resources, and M is greater than 1, the terminal determines the PC parameter of the SRS resource that is in the first SRS resource set and to which the TCI state information is applied as: the PC parameter associated with or included in the TCI state information used by the SRS resource.
Correspondingly, the method further includes:
The terminal determines, based on first identification information associated with each SRS resource in the first SRS resource set, that TCI state information used by the SRS resource is the TCI state information corresponding to the first identification information.
Optionally, the first identification information includes at least one of the following:
For example, in the mDCI scenario, the K SRS resources are respectively associated with different TRP IDs (different CORESET pool indexes). In this case, the K SRS resources respectively use TCI state information corresponding to each TRP ID, and use a PC parameter associated with or included in each piece of TCI state information.
Further, when the network configures a first SRS resource set, PC parameters associated with or included in the M pieces of TCI state information are the same, to ensure that PC parameters of all SRS resources in the first SRS resource set are the same. In other words, in this embodiment of this application, the PC parameters included in or associated with the TCI state information indicated by the network are limited to be the same.
Alternatively, when the network configures a first SRS resource set, PC parameters associated with or included in the M pieces of TCI state information are different. In other words, in this embodiment of this application, the PC parameters included in or associated with the TCI state information indicated by the network are allowed to be different.
It should be noted that, when the network configures an SRS resource set (namely, the first SRS resource set), and the set includes the K SRS resources, each SRS resource in the K SRS resources uses one piece of TCI state information indicated by the network. Different SRS resources may use same or different TCI state information.
In another optional embodiment, when M is equal to 1, all SRS resources included in the first SRS resource set use one piece of TCI state information included in the common beam information. In addition, if the TCI state information is associated with or includes a PC parameter, PC parameters of all the SRS resources included in the first SRS resource set are the PC parameter associated with or included in the TCI state information.
In another optional embodiment, when M is equal to 1, a target SRS resource in the first SRS resource set uses one piece of TCI state information included in the common beam information. Another SRS resource other than the target SRS resource may not be transmitted, or TCI state information and a PC parameter of the another SRS resource do not change.
The target SRS resource includes at least one of the following:
For example, there is a correspondence between the target SRS resource and the TCI state information indicated by the network, or the target SRS resource and the TCI state information indicated by the network correspond to a same channel group, CORESET group, or TRP ID.
In at least one embodiment of this application, step 202 in which the terminal determines, based on the PC parameter associated with or included in the TCI state information, the PC parameter of the SRS resource to which the TCI state information is applied includes:
When the network configures a plurality of second SRS resource sets, the terminal determines a PC parameter of a second SRS resource set to which the TCI state information is applied as:
PC parameters of all SRS resources included in the second SRS resource set are the same. To be specific, PC parameters of all SRS resources included in a same second SRS resource set are the same, and PC parameters of SRS resources included in different second SRS resource sets may be the same or different.
For example, the network configures P second SRS resource sets, and each second SRS resource set includes at least one SRS resource set. Optionally, the method is applied to a single-DCI scenario. P is greater than 1.
When M is greater than 1, the P second SRS resource sets respectively use one piece of TCI state information indicated by the network. TCI state information used by different second SRS resource sets may be the same or different. For example, all SRS resources in an SRS resource set A use first TCI state information, and all SRS resources in an SRS resource set B use second TCI state information. In this case, the method further includes:
The terminal determines, based on a first correspondence, the TCI state information used by the second SRS resource set, where the first correspondence includes any one of the following:
The first identification information includes at least one of the following:
When M is equal to 1, all the plurality of second SRS resource sets use one piece of TCI state information included in the common beam information. In addition, if the TCI state information is associated with or includes a PC parameter, PC parameters of the plurality of second SRS resource sets are all the PC parameter associated with or included in the TCI state information.
In an alternative case, details are as follows.
When M is equal to 1, a target second SRS resource set in the plurality of second SRS resource sets uses one piece of TCI state information included in the common beam information, and a remaining second SRS resource set may not be transmitted, or TCI state information and a PC parameter of the remaining second SRS resource set do not change.
The target second SRS resource set includes at least one of the following:
For example, there is a correspondence between the target second SRS resource set and the TCI state information, or the target second SRS resource set and the TCI state information correspond to a same channel group, CORESET group, or TRP ID.
In at least one embodiment of this application, step 202 in which the terminal determines, based on the PC parameter included in the configuration information of the sounding reference signal SRS resource set, the PC parameter of the SRS resource to which the TCI state information is applied includes:
When the network configures a first SRS resource set, the terminal determines that a PC parameter of an SRS resource that is in the first SRS resource set and that uses TCI state information that is not associated with or does not include a PC parameter is a PC parameter included in configuration information of the first SRS resource set.
Alternatively, when the network configures a first SRS resource set, the terminal determines PC parameters of all SRS resources in the first SRS resource set as PC parameters included in configuration information of the first SRS resource set.
It should be noted that, if the first SRS resource set is associated with a plurality of sets of PC parameters in the configuration information of the first SRS resource set, the plurality of sets of PC parameters may respectively correspond to the SRS resources in the first SRS resource set. Alternatively, if the first SRS resource set is associated with only one set of PC parameters in the configuration information of the first SRS resource set, the set of PC parameters is applicable to all the SRS resources in the first SRS resource set.
Alternatively, step 202 in which the terminal determines, based on the PC parameter included in the configuration information of the sounding reference signal SRS resource set, the PC parameter of the SRS resource to which the TCI state information is applied includes:
When the network configures the plurality of second SRS resource sets, the terminal determines the PC parameter of the second SRS resource set to which the TCI state information is applied as:
It should be noted that, if the second SRS resource set is associated with the plurality of sets of PC parameters in the configuration information of the second SRS resource set, a default PC parameter of the second SRS resource set may be pre-agreed. This is not specifically limited herein.
In at least one embodiment of this application, when the TCI state information is associated with or includes the PC parameter, the terminal determines, based on a target configuration, the PC parameter of the SRS resource to which the TCI state information is applied as the PC parameter associated with or included in the TCI state information or as a configured first PC parameter.
The target configuration may indicate whether all or a part of PC parameters of an SRS resource or all SRS resources included in an SRS resource set are applied to the PC parameter associated with or included in the TCI state information. For example, if the target configuration indicates a first state, the SRS resource or the SRS resource set applies the PC parameter associated with or included in the TCI state information. Alternatively, if the target configuration indicates a second state, the SRS resource or all the SRS resources included in the SRS resource set apply the preconfigured first PC parameter.
Optionally, the target configuration is an RRC parameter srs-PowerControlAdjustmentStates of the SRS resource set, and a value thereof may be sameAsFci2 or separateClosedLoop. When srs-PowerControlAdjustmentStates is configured as sameAsFci2 or srs-PowerControlAdjustmentStates is not configured, the SRS resource or all the SRS resources included in the SRS resource set use one piece of TCI state information included in the common beam information. If the TCI state information is associated with or includes the PC parameter, the PC parameter (for example, a close loop power control index (Close Loop Index, CLI)) of the SRS resource or the PC parameters of all the SRS resources included in the SRS resource set are the PC parameter associated with or included in the TCI state information. When srs-PowerControlAdjustmentStates is configured as separateClosedLoop, the SRS resource or all the SRS resources included in the SRS resource set use an additionally configured first PC parameter (for example, a close loop power control index (Close Loop Index, CLI)).
In conclusion, in this embodiment of this application, for a scenario in which a unified TCI framework is applied to a plurality of TRPs, after receiving the M pieces of TCI state information indicated by the network, the terminal determines, based on the PC parameter associated with or included in the TCI state information, the PC parameter of the SRS resource to which the TCI state information is applied, and/or determines, based on the PC parameter included in the configuration information of the sounding reference signal SRS resource set, the PC parameter of the SRS resource to which the TCI state information is applied, to ensure correctness of SRS power adjustment and SRS transmission performance.
