Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of communication, and particularly relates to a method and device for determining a power control (PC) parameter and a terminal. BACKGROUND

[0002] The significance of power control (PC) in the current technology includes: maintaining power (adjusting power according to the distance between a terminal and a base station to ensure that the power of a signal reaching the base station is close); improving performance (dynamically adjusting power according to channel changes to achieve accurate and rapid power adjustment); and reducing interference (reducing adjacent channel power leakage, reducing inter-user and inter-cell interference, and prolonging battery life).

[0003] The power control is divided as follows:

[0004] Downlink power control mainly depends on the configuration and implementation of the network side;

[0005] Uplink power control mainly includes: PC of a physical uplink shared channel (PUSCH), PC of a physical uplink control channel (PUCCH), PC of a sounding reference signal (SRS), and PC of a physical random access channel (PRACH);

[0006] It also includes: power headroom reporting (PHR), mainly for assisting base station scheduling; and power scaling / sharing, mainly for sharing power to ensure transmission of a cell / channel with a higher priority.

[0007] In one aspect, a new unified transmission configuration indicator (TCI) framework is introduced in 5G, which can be referred to as unified TCI framework, that is, the same beam indicated by a network using a media access control control element (MAC CE) and / or a downlink control information (DCI) can be used for multiple channel transmissions, and such a beam can also be referred to as a common beam. In the unified TCI framework, there are two modes, joint TCI and separate TCI, which are configured by RRC signaling of the network. The joint TCI state specifically includes: indicating that a certain TCI state is used for both uplink transmission and downlink transmission; the separate TCI state specifically includes: indicating that a certain TCI state is used for uplink transmission or downlink transmission.

[0008] On the other hand, multi-transmission-reception node (multi-TRP, which can be referred to as MTRP) transmission is introduced in 5G, and the control signaling aspect is divided into two cases: single-DCI scheduling and multi-DCI scheduling.

[0009] Multi-DCI (multi-DCI, which can be referred to as mDCI) scheduling: each TRP sends its own PDCCH, and each PDCCH schedules its own PDSCH. At this time, the multiple control resource sets (CORESETs) configured by the network for the UE are associated with different RRC parameters CORESETPoolIndex, corresponding to different TRPs;

[0010] Single-DCI (single-DCI, which can be referred to as sDCI) scheduling: a PDCCH is sent by one TRP to schedule a PDSCH. At this time, the multiple CORESETs configured by the network for the UE cannot be associated with different CORESETPoolIndex. In this case, the MAC CE activates a maximum of 8 code points, at least one of which corresponds to two TCI states. When the code point corresponding to the TCI field in a DCI corresponds to two TCI states and indicates that one of the TCI states contains "QCL-TypeD", it means that the scheduled PDSCH comes from two TRPs.

[0011] However, in the unified TCI framework, it is currently only applied to a single-TRP scenario, and there is no solution for how to determine uplink power control parameters when the unified TCI framework is applied in a multi-TRP scenario. SUMMARY

[0036] With reference to the accompanying drawings, the determination method of the power control (PC) parameter provided by the embodiments of the present application will be described in detail in combination with some embodiments and application scenarios.

[0037] Please refer to Figure 2 , Figure 2 The step flowchart of the determination method of the PC parameter provided by the embodiments of the present application, the PC parameter determination method comprises:

[0038] Step 201, the terminal receives the common beam information configured by the network side device, the beam information comprises: M joint transmission configuration indication (TCI) state information, or M independent TCI state information, wherein M is an integer greater than or equal to 1;

[0039] In this step, the M joint TCI state information can be understood as M TCI state information used for uplink transmission and downlink transmission at the same time. The M independent TCI state information can be understood as M TCI state information used for uplink transmission, or M TCI state information used for downlink transmission, or M1 TCI state information used for uplink transmission and M2 TCI state information used for downlink transmission, and M1+M2 is equal to M. It should be noted that the "TCI state information" mentioned in the embodiments of the present application can be any one of the above-mentioned M joint TCI state information, or any one of the above-mentioned M independent TCI state information, which is not limited here.

[0040] Step 202, in the case that the TCI state information is associated with or contains the PC parameter, the terminal determines the PC parameter of the SRS resource applying the TCI state information according to the PC parameter associated with or contained by the TCI state information; and / or, in the case that the TCI state information is not associated with or does not contain the PC parameter, the terminal determines the PC parameter of the SRS resource applying the TCI state information according to the PC parameter included in the configuration information of the SRS resource set.

[0041] It should be noted that the "PC parameter" in the "case that the TCI state information is associated with or contains the PC parameter" and the "case that the TCI state information is not associated with or does not contain the PC parameter" mentioned in the embodiments of the present application can be a set of PC parameters, or part of the PC parameters in a set of PC parameters. Wherein, a set of PC parameters comprises: a loss estimation reference signal and / or a parameter set (setting), the parameter set comprises: at least one of an open loop receiving end power target value P0, a partial loss compensation factor α and a closed loop power control index CLI.

[0042] If the PC parameter is part of the PC parameter in a set of PC parameters, for example, the TCI state information is associated with or contains the first part of the PC parameter in a set of PC parameters (the TCI state information is not associated with or does not contain the second part of the PC parameter in the set of PC parameters), the first part of the PC parameter of the SRS resource applying the TCI state information is the first part of the PC parameter associated with or contained by the TCI state information; and the second part of the PC parameter of the SRS resource applying the TCI state information is determined by the configuration information of the SRS resource set.

[0043] It should be noted that in the case where M is greater than 1, the M TCI state information can be associated with or contain the PC parameter, or the M TCI state information can not be associated with or contain the PC parameter, or part of the M TCI state information is associated with or contains the PC parameter, and part of the M TCI state information is not associated with or contains the PC parameter.

[0044] Optionally, in the case where M is greater than 1, M can be understood as the number of TRPs, for example, M is equal to 2, and the plurality of TCI state information is the TCI state information corresponding to each TRP, respectively. In the case where M is equal to 1, the one TCI state information is the TCI state information of a certain TRP in the multi-TRP or the TCI state information common to all TRPs.

[0045] It should be noted that in the multi-TRP scenario applied in the embodiments of the present application, for the case where N is equal to 1, there are the following two cases:

[0046] Case 1: In the case of multi-DCI scheduling, the terminal can determine that it is in the multi-DCI mode of the multi-TRP scenario according to the network configuring a plurality of different TRP ID information (such as the RRC parameter CORESETPoolIndex). In this 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 one TCI state information, and the one TCI state information can be used to determine that the scheduled channel corresponds to a certain TRP in the multi-TRP (where the uplink channel applying the TCI state information can be understood as the uplink channel of the TRP corresponding to the TCI state information).

[0047] Case 2, in the single-DCI scheduling case, the terminal can indirectly determine that it is in a multi-TRP scenario according to the configuration information of the network, 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 channel scheduled by the DCI corresponds to one or more TRPs according to the TCI state corresponding to the code point indicated by the received DCI. When the code point indicated by the DCI corresponds to one TCI state, the one TCI state can be used to determine that the uplink channel scheduled by the DCI applies the one TCI state information and corresponds to one of the multiple TRPs.

[0048] As an optional embodiment, the PC parameter comprises a path loss estimation reference signal (PLRS) and / or a parameter set (setting), and the parameter set comprises at least one of an open-loop receive end power target value P0, a partial path loss compensation factor a, and a closed-loop power control index CLI.

[0049] As an optional embodiment, the network can configure one SRS resource set, or the network can also configure multiple SRS resource sets.

[0050] In at least one embodiment of the present application, in the case where the TCI state information is associated with or contains the PC parameter in step 202, the terminal determines the PC parameter of the SRS resource applying the TCI state information according to the PC parameter associated with or contained in the TCI state information, comprising:

[0051] In the case where the network configures a first SRS resource set, the terminal determines the PC parameter of the SRS resource applying the TCI state information in the first SRS resource set as:

[0052] The PC parameter associated with or contained in the TCI state information used by the SRS resource; or

[0053] The PC parameter associated with or contained in the preset TCI state information.

[0054] For example, the first SRS resource set comprises K SRS resources, and K is an integer greater than or equal to 1. Optionally, the multi-DCI scenario for multi-TRP is applied.

[0055] As an optional embodiment, in the case where K is equal to 1, i.e., in the case where the first SRS resource set comprises one SRS resource, the terminal determines that the SRS resource uses the preset TCI state information, and the PC parameter of the SRS resource is the PC parameter associated with or contained in the preset TCI state information; wherein the preset TCI state information is any one of the following:

[0056] Pth TCI state information in the M TCI state information; such as P equals to 1, or P equals to 2, etc., the value of P is configured by the network or pre-agreed;

[0057] TCI state information corresponding to the same first identification information as the SRS resource; such as the Pth TCI state information in the M TCI state information corresponds to a certain first identification information, and the SRS resource also corresponds to the same first identification information, then the SRS resource uses the Pth TCI state information;

[0058] TCI state information corresponding to the SRS resource; such as the correspondence between the SRS resource and the TCI state information is configured by the network or pre-agreed;

[0059] Optionally, the first identification information includes at least one of the following:

[0060] Identification information of a control resource set CORESET;

[0061] Identification information of a CORESET pool;

[0062] Identification information of a transmission receiving node TRP;

[0063] Identification information of a channel group;

[0064] Identification information of a CORESET group;

[0065] Identification information of a physical uplink control channel PUCCH resource group.

[0066] As another optional embodiment, in the case where K is greater than or equal to 2 (such as K equals to 2), that is, the first SRS resource set includes multiple SRS resources, and M is greater than 1, the terminal determines the PC parameter of the SRS resource in the first SRS resource set that applies the TCI state information as:

[0067] The PC parameter associated with or contained in the TCI state information used by the SRS resource.

[0068] Correspondingly, the method further includes:

[0069] The terminal determines, according to the first identification information associated with each SRS resource in the first SRS resource set, the TCI state information used by the SRS resource as the TCI state information corresponding to the first identification information.

[0070] Optionally, the first identification information includes at least one of the following:

[0071] Identification information of a control resource set CORESET;

[0072] identification information of a CORESET pool;

[0073] identification information of a transmission receiving point, TRP;

[0074] identification information of a channel group;

[0075] identification information of a CORESET group;

[0076] identification information of a physical uplink control channel, PUCCH resource group.

[0077] For example, in the mDCI scenario, the K SRS resources are respectively associated with different TRP IDs (different CORESET pool indexes); then the K SRS resources respectively use the TCI state information corresponding to each TRP ID, and use the PC parameters associated with or contained in each TCI state information.

[0078] Further, in the case where the network configures a first SRS resource set, the PC parameters associated with or contained in the M TCI state information are the same, thereby ensuring that the PC parameters of all SRS resources in the first SRS resource set are the same; that is, the PC parameters associated with or contained in the TCI state information indicated by the network are the same in the embodiment of the application.

[0079] Alternatively, in the case where the network configures a first SRS resource set, the PC parameters associated with or contained in the M TCI state information are different; that is, the PC parameters associated with or contained in the TCI state information indicated by the network are different in the embodiment of the application.

[0080] It should be noted that when the network configures 1 SRS resource set (i.e., a first SRS resource set) and includes K SRS resources in the set, each SRS resource in the K SRS resources respectively uses 1 of the TCI state information indicated by the network, wherein the TCI state information used by different SRS resources can be the same or different.

[0081] As another optional embodiment, in the case where M is equal to 1, all SRS resources included in the first SRS resource set use 1 TCI state information included in the common beam information. If the TCI state information is associated with or contains PC parameters, the PC parameters of all SRS resources included in the first SRS resource set are the PC parameters associated with or contained in the TCI state information.

[0082] As another optional embodiment, in the case of M being equal to 1, the target SRS resource in the first SRS resource set uses 1 TCI state information included in the common beam information; other SRS resources except the target SRS resource can no longer be transmitted, or the TCI state information and PC parameters of other SRS resources remain unchanged.

[0083] The target SRS resource includes at least one of the following:

[0084] The SRS resource corresponding to the 1 TCI state;

[0085] The SRS resource corresponding to the 1 TCI state with the same first identification information. Optionally, the first identification information includes at least one of the following:

[0086] The identification information of the control resource set CORESET;

[0087] The identification information of the CORESET pool;

[0088] The identification information of the transmission receiving node TRP;

[0089] The identification information of the channel group;

[0090] The identification information of the CORESET group;

[0091] The identification information of the physical uplink control channel PUCCH resource group.

[0092] For example, the target SRS resource has a corresponding relationship with the TCI state indicated by the network, or the target SRS resource corresponds to the same channel group or CORESET group or TRP ID as the TCI state indicated by the network.

[0093] In at least one embodiment of the present application, the terminal determines the PC parameters of the SRS resource applying the TCI state information according to the PC parameters associated with or contained in the TCI state information in step 202, including:

[0094] In the case of the network configuring multiple second SRS resource sets, the terminal determines the PC parameters of the second SRS resource set applying the TCI state information as:

[0095] The PC parameters associated with or contained in the TCI state information used by the second SRS resource set;

[0096] The PC parameters of all SRS resources included in the second SRS resource set are the same. That is, the PC parameters of all SRS resources included in the same second SRS resource set are the same, and the PC parameters of SRS resources included in different second SRS resource sets can be the same or different.

[0097] For example, the network configures P second SRS resource sets, each of which includes at least one SRS resource set. Optionally, it is applied to a single-DCI scenario. P is greater than 1.

[0098] In the case where M is greater than 1, the P second SRS resource sets use 1 of the network indicated TCI state information respectively. The TCI state information used by different second SRS resource sets can be the same or different. For example, all SRS resources in SRS resource set A use first TCI state information, and all SRS resources in SRS resource set B use second TCI state information. In this case, the method further includes:

[0099] The terminal determines the TCI state information used by the second SRS resource set according to the first correspondence relationship. The first correspondence relationship includes any one of the following:

[0100] The correspondence relationship between the SRS resource set and the identifier of the TCI state information;

[0101] The correspondence relationship between the SRS resource set and the first identifier information.

[0102] The first identifier information includes at least one of the following:

[0103] The identifier information of the CORESET;

[0104] The identifier information of the CORESET pool;

[0105] The identifier information of the TRP;

[0106] The identifier information of the channel group;

[0107] The identifier information of the CORESET group;

[0108] The identifier information of the PUCCH resource group.

[0109] In the case where M is equal to 1, the plurality of second SRS resource sets all use 1 TCI state information included in the common beam information; and if the TCI state information is associated with or contains PC parameters, the PC parameters of the plurality of second SRS resource sets are the PC parameters associated with or contained in the TCI state information.

[0110] Or,

[0111] In the case where M is equal to 1, a target second SRS resource set in the plurality of second SRS resource sets uses 1 TCI state information included in the common beam information; the remaining second SRS resource sets can no longer be transmitted, or the TCI state information and PC parameters of the remaining second SRS resource sets remain unchanged.

[0112] The target second SRS resource set includes at least one of the following:

[0113] A second SRS resource set having a corresponding relationship with the 1 TCI state information;

[0114] A second SRS resource set corresponding to the same first identification information as the 1 TCI state. The first identification information includes at least one of the following:

[0115] Identification information of a CORESET;

[0116] Identification information of a CORESET pool;

[0117] Identification information of a TRP;

[0118] Identification information of a channel group;

[0119] Identification information of a CORESET group;

[0120] Identification information of a PUCCH resource group.

[0121] For example, the target second SRS resource set has a corresponding relationship with the TCI state information, or the target second SRS resource set corresponds to the same channel group or CORESET group or TRP ID as the TCI state information.

[0122] In at least one embodiment of the present application, the terminal determines the PC parameters of the SRS resource to which the TCI state information is applied according to the PC parameters included in the configuration information of the SRS resource set in step 202, including:

[0123] In the case where the network configures a first SRS resource set, the terminal determines the PC parameters of the SRS resource in the first SRS resource set using the TCI state information without association or without containing PC parameters as the PC parameters included in the configuration information of the first SRS resource set;

[0124] Or, in the case where the network configures a first SRS resource set, the terminal determines the PC parameters of all SRS resources in the first SRS resource set as the PC parameters included in the configuration information of the first SRS resource set.

[0125] It should be noted that if the configuration information of the first SRS resource set associates multiple sets of PC parameters, the multiple sets of PC parameters can correspond to each SRS resource in the first SRS resource set respectively; if the configuration information of the first SRS resource set only associates one set of PC parameters, the one set of PC parameters is applicable to all SRS resources of the first SRS resource set.

[0126] Alternatively, the terminal in step 202 determines the PC parameters of the SRS resource to which the TCI state information is applied according to the PC parameters included in the configuration information of the SRS resource set, including:

[0127] In the case where the network configures multiple second SRS resource sets, the terminal determines the PC parameters of the second SRS resource set to which the TCI state information is applied as:

[0128] The PC parameters included in the configuration information of the second SRS resource set; wherein the PC parameters of all SRS resources included in the second SRS resource set are the same.

[0129] It should be noted that if the configuration information of the second SRS resource set associates multiple sets of PC parameters, the default PC parameters of the second SRS resource set can be pre-agreed, which is not limited here.

[0130] In at least one embodiment of the present application, in the case where the TCI state information associates or contains PC parameters, the terminal determines the PC parameters of the SRS resource to which the TCI state information is applied according to the target configuration as the PC parameters associated or contained by the TCI state information or as the configured first PC parameters.

[0131] Wherein, the target configuration can indicate whether all or part of the PC parameters of the SRS resource or all SRS resources included in the SRS resource set apply the PC parameters associated or contained by the TCI state information. For example, if the target configuration indicates a first state, the SRS resource or SRS resource set applies the PC parameters associated or contained by the TCI state information; if the target configuration indicates a second state, all SRS resources included in the SRS resource or SRS resource set apply the first PC parameters pre-configured.
