In a conventional mobile communication system based on fourth generation (4G) mobile communication technology, a Sounding Reference Signal (SRS) is mainly used for acquiring uplink or downlink Channel State Information (CSI). Specifically, a power at which a terminal, for example, a User Equipment (UE) sends an SRS on a subframe i is: P_SRS(i)=min{P_CMAX, P_{SRS_OFFSET}10 log₁₀(M_SRS) P_{O_PUSCH}(j) α(j)·PL+f(i)} where P_CMAXrepresents the maximum transmission power configured by the UE; P_{SRS_OFFSET}represents a semi-static parameter of the UE configured by a higher layer, which is divided into two cases, in a case that K_S=1.25, then a range of P_{SRS_OFFSET}is [−3,12] db and a step size is 1 db; in a case that K_S=0, then the range of P_{SRS_OFFSET}is [−10.5, 12] and the step size is 1.5 db; M_SRSrepresents a transmission bandwidth of the SRS, which is expressed by the number of resource blocks (RBs); f (i) represents a current power adjustment value of a Physical Uplink Sharing Channel (PUSCH); both P_{O_PUSCH}(j) and α(j) are values related to the PUSCH, j=1; PL represents a value of the path loss.

In a future mobile communication system, for example, a mobile communication system based on a fifth generation (5G) mobile communication technology, an SRS can be used not only for acquiring uplink or downlink CSI, but also be used for beam management. However, in the related art, there is no related solution for how to perform power control of resources for uplink beam management.

Specifically, in some embodiments of the present disclosure, uplink power control relates to the following: in a New Radio (NR) system, a Physical Uplink Sharing Channel (PUSCH) and a part of all types of Sounding Reference Signal (SRS) share the same closed-loop power control command; PUSCH and Physical Uplink Control Channel (PUCCH) rely on independent power control commands; power control of an inter-carrier handover of the SRS; calculation of a path loss (i.e., Path Loss) supports at least a periodic Channel State Information Reference Signal (CSI-RS) calculation, and is applicable to PUSCH, PUCCH, and SRS.

Specifically, the SRS may be used not only for acquiring uplink or downlink Channel State Information (CSI), but also for beam management. In order to facilitate a network device (e.g., a base station) to better evaluate a quality (superior or inferior) of an uplink beam of a terminal, such as a User Equipment (UE), transmission powers of uplink beam management resources used for an uplink beam management procedure is preferably the same in the uplink beam measurement process when an SRS or another resource (e.g., a resource of a physical uplink shared channel) is used for uplink beam management). Accordingly, the embodiments of the present disclosure provide a power control method of an uplink beam management resource in an uplink beam management procedure so as to regulate power control of the uplink beam management resource in the uplink beam management procedure, further improve an efficiency of uplink beam management and improve an uplink transmission speed.

Referring to FIG. 1, FIG. 1 is a schematic diagram of a network structure to which some embodiments of the present disclosure are applicable, and as shown in FIG. 1, the network structure includes a network device 10 and a terminal 20, wherein the terminal 20 can communicate with the network device 10 through a network. The network device 10 may be an Evolutional base station (an Evolutional Node B, or eNB or eNodeB for short), a relay station or an access point, or a base station in a 5G network (gNB), or a radio network controller on a network side or a terminal (simply referred to as a UE), which is not limited herein. The terminal 20 may be a mobile phone, a Tablet Personal Computer, a Laptop Computer, a Personal Digital Assistant (PDA), a Mobile Internet Device (MID) or a Wearable Device or the like.

In the embodiments of the present disclosure, the network device 10 configures a power control parameter for a resource in an uplink beam management resource set used for an uplink beam management procedure, and sends the power control parameter to the terminal 20. The uplink beam management includes a plurality of identical or different beam transmission resources being adopted by the terminal.

The resource set may include one or more of an SRS resource set, a Physical Random Access Channel (PRACH) resource set and a Physical Uplink Control Channel (PUCCH) resource set, each of one or more of the SRS resource set, the PRACH resource set, and the PUCCH resource set includes resources corresponding to the same resource identifier and/or resources corresponding to different resource identifiers.

The above power control parameter may include one or more of an open-loop power control parameter set, a closed-loop power control parameter set, and a transmission power, wherein the open-loop power control parameter set may include, but is not limited to, one or more of a target reception power, a path loss compensation factor, and a power offset. The closed-loop power control parameter set may include, but is not limited to, one or more of a power adjustment value, the number of resource blocks, and a modulation and coding scheme.

Optionally, the network device 10 may configure the common power control parameter for the same resource or different resources in the same uplink beam management resource set used for the uplink beam management procedure, so that the terminal 20 sends the resources in the uplink beam management resource set using the same transmission power in the uplink beam management procedure.

Optionally, the network device 10 may send the above-described power control parameter to the terminal 20 through a higher-layer (i.e., Higher Layer) signaling.

After the terminal receives the power control parameter sent by the network device 10, the terminal 20 may send the resources in the uplink beam management resource set according to the power control parameter. For example, in a case that the power control parameter is the transmission power, the terminal 20 may send the resources in the uplink beam management resource set using the transmission power. In a case that the power control parameter is a path loss value, the terminal 20 may calculate a transmission power using the path loss value, and further send resources in the uplink beam management resource set using the transmission power. In a case that the power control parameter is a reference beam set, the terminal 20 may calculate a path loss value using the reference beam set, and further calculate a transmission power, and further send the resources in the uplink beam management resource set using the transmission power. In a case that the power control parameter is the open-loop power control parameter set and/or the closed-loop power control parameter set, the terminal 20 may calculate a transmission power according to the open-loop power control parameter set and/or the closed-loop power control parameter set, and further send the resources in the uplink beam management resource set using the transmission power.

Optionally, in some embodiments of the present disclosure, in a case that the power control parameters for the resources in the uplink beam management resource set used for the uplink beam management procedure are the same, the terminal 20 may send respective resources in the uplink beam management resource set used for the uplink beam management procedure using the same transmission power, so that the network device (e.g., the base station) may better evaluate the quality of an uplink beam.

In this way, in some embodiments of the present disclosure, the network device 10 configures the power control parameter for the uplink beam management resource set, and sends the power control parameter to the terminal 20. Thus, the terminal 20 may send the resource used for the uplink beam management based on the power control parameter configured by the network side, and may control a signaling overhead of the power control of the uplink beam management resources used for the uplink beam management procedure.

The embodiments of the present disclosure provide a power control method. The method is applied to a network device. Referring to FIG. 2, FIG. 2 is a flowchart of a power control method provided by some embodiments of the present disclosure, and as shown in FIG. 2, the method includes the following steps 201-202.

Step 201: configuring a power control parameter for a resource in an uplink beam management resource set used for an uplink beam management procedure.

In some embodiments of the present disclosure, the uplink beam management procedure may include an identical beam or a plurality of different beams being adopted by a user equipment.

The uplink beam management resource set may include one or more of an SRS resource set, a PRACH resource set, and a PUCCH resource set, wherein the SRS resource set may include one or more SRS resources, the PRACH resource set may include one or more PRACH resources and the PUCCH resource set may include one or more PUCCH resources.

Optionally, each of one or more of the SRS resource set, the PRACH resource set, and the PUCCH resource set may include resources corresponding to the same resource identifier and/or resources corresponding to different resource identifiers, wherein, resources corresponding to the same resource identifier are the same, and resources corresponding to different resource identifiers are different. For example, in a case that the uplink beam management resource set includes the SRS resource set and the PRACH resource set, the SRS resource set may include SRS resources corresponding to the same resource identifier and/or SRS resources corresponding to different resource identifiers. Similarly, the PRACH resource set may also include PRACH resources corresponding to the same resource identifier and/or PRACH resources corresponding to different resource identifiers.

Optionally, the above power control parameter is used for power control of resources in the uplink beam management resource set. For example, the above power control parameter may include, but is not limited to, one or more of the open-loop power control parameter set, the closed-loop power control parameter set and the transmission power.

Optionally, the open-loop power control parameter set may include, but is not limited to, one or more of a target reception power, a path loss compensation factor, and a power offset; the closed-loop power control parameter set may include, but is not limited to, one or more of a power adjustment value, the number of resource blocks, and a modulation and coding scheme.

It will be understood that the embodiments of the present disclosure may reasonably configure the above-described power control parameter according to actual conditions.

It will be understood that the embodiments of the present disclosure may configure only one power control parameter for all resources in the uplink beam management resource set in the uplink beam management procedure, and may also configure a power control parameter for each resource in the uplink beam management resource set in the uplink beam management procedure.

Step 202: sending the power control parameter to the terminal, so that the terminal sends a resource in the uplink beam management resource set according to the power control parameter.

In some embodiments of the present disclosure, the network device sends, to a terminal, the power control parameter configured for the resources in the uplink beam management resource set used for the uplink beam management procedure. Thus, the terminal may send, according to the power control parameters configured by the network device, the resources in the uplink beam management resource set used for the uplink beam management procedure. For example, in a case that the power control parameter is the transmission power, the terminal may send the resources in the uplink beam management resource set using the transmission power; in a case that the power control parameter is the path loss value, the terminal may calculate a transmission power according to the path loss value, and further send the resources in the uplink beam management resource set using the transmission power; in a case that the power control parameter is a reference beam set identifier, the terminal may calculate a path loss value according to the reference beam set identifier, further calculate a transmission power, and further send the resources in the uplink beam management resource set using the transmission power, wherein the reference beam set may include one or more reference beam identifiers; in a case that the power control parameter is the open-loop power control parameter set and/or the closed-loop power control parameter set, the terminal may calculate a transmission power according to the open-loop power control parameter set and/or the closed-loop power control parameter set, and further send the resources in the uplink beam management resource set using the transmission power.

Thus, the power control method according to some embodiments of the present disclosure configures the power control parameter for the resources in the uplink beam management resource set used for the uplink beam management procedure, and sends the power control parameter to the terminal, such that the terminal sends the resources in the uplink beam management resource set according to the power control parameter. In this way, power control of the resources in the uplink beam management resource set used for the uplink beam management procedure is realized, and the signaling overhead of the power control of an uplink beam management resource used for the uplink beam management procedure can be controlled.

Optionally, the uplink beam management resource set includes one or more of a Sounding Reference Signal (SRS) resource set, a Physical Random Access Channel (PRACH) resource set, and a Physical Uplink Control Channel (PUCCH) resource set, wherein, each of one or more of the SRS resource set, the PRACH resource set, and the PUCCH resource set includes resources corresponding to the same resource identifier and/or resources different resource identifiers.

The power control parameter includes one or more of an open-loop power control parameter set, a closed-loop power control parameter set, a transmission power, a path loss value, and a reference beam set identifier.

In some embodiments of the present disclosure, the SRS resource set may include one or more SRS resources. The PRACH resource set may include one or more PRACH resources. The PUCCH resource set may include one or more PUCCH resources. Each of the above SRS resource set, the PRACH resource set, and the PUCCH resource set may include the same resource and/or different resources. For example, the PRACH resource set may include PRACH resources having the same channel type and the same beam, and/or PRACH resources having different channel types or PRACH resources having the same channel type but different beams. In particular, the embodiments of the present disclosure may identify the same resource and different resources according to a resource identifier, and accordingly, each of the above SRS resource set, the PRACH resource set and the PUCCH resource set may include resources corresponding to the same resource identifier and/or resources different resource identifiers.

The reference beam set identifier described above may include one or more reference beam identifiers.

The power control parameter described above may include, but is not limited to, one or more of an open-loop power control parameter set, a closed-loop power control parameter set, and a transmission power, wherein the open-loop power control parameter set may include one or more open-loop power control parameters, such as a target reception power, a path loss compensation factor, and so on; the closed-loop power control parameter set may include one or more closed-loop power control parameters, for example, a power adjustment value, the number of resource blocks, and the like. It will be understood that the embodiments of the present disclosure may reasonably configure the above-described power control parameter according to actual conditions.

Optionally, the open-loop power control parameter set includes one or more of a target reception power, a path loss compensation factor, and a power offset; and the closed-loop power control parameter set includes one or more of a power adjustment value, the number of resource blocks, and a modulation and coding scheme.

In some embodiments of the present disclosure, the open-loop power control parameter set may include, but is not limited to, one or more of a target reception power, a path loss compensation factor, a power offset; the closed-loop power control parameter set may include, but is not limited to, one or more of a power adjustment value, the number of resource blocks, a modulation and coding scheme.

It may be understood that the embodiments of the present disclosure may reasonably configure the open-loop power control parameter set and the closed-loop power control parameter set as described above according to actual conditions.

Optionally, the above step 201 of configuring the power control parameter for the resource in the uplink beam management resource set used for the uplink beam management procedure, includes: configuring the common power control parameter for resources in the uplink beam management resource set used for the uplink beam management procedure; or configuring a corresponding power control parameter for each resource in the uplink beam management resource set used for the uplink beam management procedure, respectively, wherein corresponding power control parameters for respective resources are the same.

In the embodiments of the present disclosure, only one power control parameter may be configured for all resources in the beam management resource set used for the uplink beam management procedure. That is, all resources in the uplink beam management resource set used for the uplink beam management procedure correspond to the common power control parameter, so that the terminal sends all resources in the beam management resource set according to the common power control parameter. Optionally, the embodiments of the present disclosure may also configure one power control parameter for respective resource in the beam management resource set used for the uplink beam management procedure. That is, each resource in the beam management resource set used for the uplink beam management procedure corresponds to one power control parameter, so that the terminal can control sending of each resource according to the power control parameter corresponding to the each resource. It should be noted that, in order for the network device to better evaluate the quality of the uplink beam of the terminal, power control parameters corresponding to respective resources are the same, so that the terminal can send each resource with the same transmission power.

Optionally, the open-loop power control parameter set and/or the closed-loop power control parameter set are determined by a downlink beam or a downlink beam pair used to calculate a path loss value of a resource in the uplink beam management resource set, or, determined by an uplink beam or an uplink beam pair corresponding to the downlink beam or the downlink beam pair used to calculate a path loss value of a resource in the uplink beam management resource set; or the open-loop power control parameter set and/or the closed-loop power control parameter set are determined based on a reference power control parameter, wherein, the reference power control parameter includes a power control parameter of a Physical Uplink Shared Channel (PUSCH) or a power control parameter of a Physical Random Access Channel (PRACH) or a power control parameter of a Physical Uplink Control Channel (PUCCH) or a power control parameter of a Sounding Reference Signal (SRS); and/or the path loss value is calculated from one or more Reference Signal Receiving Power (RSRP) values reported by the terminal based on a channel state information reference signal (CSI-RS) set and/or a synchronization signal block set; and/or the reference beam set identifier is determined based on a beam reported by a terminal.

The synchronization signal block set may be, for example, a Synchronization Signal (SS) block (i.e., Block) in a 5G system. It may be understood that the above synchronization signal block set may also be synchronization signal blocks in other mobile communication systems. The RSRP may be a first-layer RSRP (L1-RSRP), or a third-layer RSRP (L3-RSRP).

In some embodiments of the present disclosure, the open-loop power control parameter set and/or the closed-loop power control parameter set may be determined based on a downlink beam or a downlink beam pair used to calculate a path loss value of a resource in the uplink beam management resource set, or, determined based on an uplink beam or an uplink beam pair corresponding to the downlink beam or the downlink beam pair used to calculate a path loss value of a resource in the uplink beam management resource set.

In particular, the terminal may calculate the path loss value based on a periodic or semi-persistent Channel State Information Reference Signal (CSI-RS) set and/or synchronization signal block set, wherein the CSI-RS set may include one or more CSI-RSs, the synchronization signal block set may include one or more synchronization signal blocks. It should be noted that the above periodic CSI-RS set and/or synchronization signal block set may refer to a set of periodically sent CSI-RSs and/or a set of periodically sent synchronization signal blocks. The semi-persistent CSI-RS set and/or synchronization signal block set described above may refer to a set of CSI-RSs periodically sent within a time period (e.g., which may be determined by a configured start time point and a configured end time point), and/or a set of synchronization signal blocks periodically sent over a time period.

For example, the terminal may take the maximum of the path loss values of transmission beams or transmission beam pairs of at least two CSI-RSs and/or at least two synchronization signal blocks as the path loss value corresponding to the resource in the uplink beam management resource set; or take the minimum of the path loss values of transmission beams or transmission beam pairs of at least two CSI-RSs and/or at least two synchronization signal blocks as the path loss value corresponding to the resource in the uplink beam management resource set; or take an intermediate value among the path loss values of transmission beams or transmission beam pairs of at least two CSI-RSs and/or at least two synchronization signal blocks as the path loss value corresponding to the resource in the uplink beam management resource set; or take a weighted average value of the path loss values of transmission beams or transmission beam pairs of at least two CSI-RSs and/or at least two synchronization signal blocks as the path loss value corresponding to the resource in the uplink beam management resource set.

For example, taking as an example a case that the maximum value between the path loss value “a” of the transmission beam or the transmission beam pair for a CSI-RS having an identifier “a” and the path loss value “b” of the transmission beam or the transmission beam pair for a CSI-RS having an identifier “b” is taken as the path loss value corresponding to the resource in the uplink beam management resource set; in a case that the path loss value “a” is greater than the path loss value “b”, the path loss value corresponding to the resource in the uplink beam management resource set is the path loss value “a”, and the open-loop power control parameter set and/or the closed-loop power control parameter set described above may be determined based on the downlink beam or the downlink beam pair used to calculate the path loss value “a”, i.e., the transmission beam or the transmission beam pair for the CSI-RS having the identifier “a”, or based on the uplink beam or the uplink beam pair corresponding to the transmission beam or the transmission beam pair for the CSI-RS having the identifier “a”.

Optionally, the open-loop power control parameter set and/or the closed-loop power control parameter set may also be determined based on the reference power control parameter, wherein, the reference power control parameter includes a power control parameter of the Physical Uplink Shared Channel (PUSCH) or a power control parameter of the Physical Random Access Channel (PRACH) or a power control parameter of the Physical Uplink Control Channel (PUCCH) or a power control parameter of the Sounding Reference Signal (SRS).

Optionally, the open-loop power control parameter set and/or the closed-loop power control parameter set may be configured by referring to the power control parameter of the PUSCH currently or historically sent, or referring to the power control parameter of the PRACH currently or historically sent, or referring to the power control parameter of the SRS currently or historically sent. In particular, the open-loop power control parameter set and/or the closed-loop power control parameter set may be configured by referring to the power control parameter of the PUSCH most recently sent, or referring to the power control parameter of the PRACH most recently sent, or referring to the power control parameter of the SRS most recently sent.

For example, in a case that the open-loop power control parameter set includes the target reception power, a target reception power “a” of the PUSCH most recently sent may be used as the target reception power in the open-loop power control parameter set.

Optionally, the path loss value may be calculated according to one or more Reference Signal Receiving Power (RSRP) values reported by the terminal based on the channel state information reference signal (CSI-RS) set and/or the synchronization signal block set.

In the embodiments of the present disclosure, the network device may calculate the path loss value according to the one or more Reference Signal Receiving Power (RSRP) reported by the terminal based on the CSI-RS set and/or the synchronization signal block set, and send the path loss value to the terminal, so that the terminal calculates a transmission power according to the path loss value. It may be understood that the above CSI-RS set and/or the synchronization signal block set may be configured by the network device for the terminal, or may be configured by the terminal.

Optionally, the above step 201 of configuring the power control parameter for the resource in the uplink beam management resource set used for the uplink beam management procedure includes: configuring a part of power control parameters in the open-loop power control parameter set and/or a part of power control parameters in the closed-loop power control parameter set for resources in the uplink beam management resource set used for the uplink beam management procedure.

In the embodiments of the present disclosure, a part of power control parameters in the open-loop power control parameter set and/or a part of power control parameters in the closed-loop power control parameter set may also be configured for the resource in the uplink beam management resource set used for the uplink beam management procedure. Optionally, a part of the power control parameters in the open-loop power control parameter set and/or a part of the closed-loop power control parameter set may be configured in conjunction with a power control parameter configured by a terminal side, e.g., in a case that the terminal side configures the target reception power, the network device side may configure one or more of remaining power control parameters other than the target reception power, for example, the path loss compensation factor, the power offset, and the like.

Specifically, the network device sends a part of power control parameters in the open-loop power control parameter set and/or a part of power control parameters in the closed-loop power control parameter set to the terminal, so that the terminal may calculate a transmission power based on the part of the power control parameters in the open-loop power control parameter set and/or the part of the power control parameters in the closed-loop power control parameter set configured by the network device, in conjunction with the power control parameter configured by the terminal side, so that the transmission power can be used to send resource in the resource set.

Optionally, configuration of the power control parameter at the terminal side may be performed by referring to the power control parameter of the PUSCH most recently sent or the power control parameter of the PRACH most recently sent or the power control parameter of the PUCCH most recently sent or the power control parameter of the SRS most recently sent. For example, in a case that the terminal side needs to configure the target reception power of the resources of the resource sets, the target reception power of the PUSCH most recently sent may be used as the target reception power of the resources of the resource sets.

The embodiments of the present disclosure configure a part of power control parameters in the open-loop power control parameter set and/or a part of power control parameters in the closed-loop power control parameter set only for the resource in the uplink beam management resource set used for the uplink beam management procedure, and may reduce a control signaling overhead.

Optionally, the method further includes: configuring a channel state information reference signal (CSI-RS) set or a synchronization signal block set for calculating a path loss value of the resource in the uplink beam management resource set, and sending the CSI-RS set or the synchronization signal block set to the terminal; or configuring a measurement resource set and sending the measurement resource set to the terminal.

In some embodiments of the present disclosure, the network device may configure a channel state information reference signal (CSI-RS) set or a synchronization signal block set for calculating a path loss value of the resource in the uplink beam management resource set, and send the channel state information reference signal (CSI-RS) set or the synchronization signal block set to the terminal, so that the terminal may calculate the path loss value of the resource in the resource set based on the CSI-RS set or the synchronization signal block set sent by the network device, wherein the CSI-RS set may include one or more CSI-RS, and the synchronization signal block set described above may include one or more synchronization signal blocks.

Optionally, the network device in some embodiments of the present disclosure may also configure a measurement resource set and send the measurement resource set to the terminal, wherein the measurement resource set includes a plurality of measurement resources, and the plurality of measurement resources may be CSI-RSs or synchronization signal blocks.

Optionally, the terminal determines the CSI-RS set or the synchronization signal block set used to calculate the path loss value of the resource in the uplink beam measurement resource set, according to a Reference Signal Receiving Power (RSRP) or a Signal to Interference Plus Noise Ratio (SINR) of each measurement resource. For example, N measurement resources with relatively larger RSRPs or relatively larger SINRs may be obtained from M measurement resources and taken as a CSI-RS set or a synchronization signal block set for calculating path loss value of the resource in the uplink beam management resource set, where M, N are all positive integers, M>=N.

Thus, the terminal can directly send the resource in the uplink beam management resource set using the transmission power.

It should be noted that the above periodic CSI-RS set and/or synchronization signal block set may be a set of CSI-RSs periodically sent and/or a set of synchronization signal blocks periodically sent. The semi-persistent CSI-RS set and/or synchronization signal block set described above may be a set of CSI-RSs periodically sent within a time period (e.g., which may be determined by a configured start time point and a configured end time point), and/or a set of synchronization signal blocks periodically sent over a time period. The above RSRP may include an L3-RSRP or an L1-RSRP.

In some embodiments of the present disclosure, the transmission power is configured for the uplink beam management resource used for the uplink beam management procedure by the network side, so that a control signaling overhead can be effectively reduced.

For example, a power control parameter “a” is configured for the resource in the uplink beam management resource set used for an uplink beam management procedure “a”, a power control parameter “b” is configured for the resources in the uplink beam management resource set used for the uplink beam management procedure “b”, where the power control parameter “a” and the power control parameter “b” are different.

Referring to FIG. 3, FIG. 3 is a flowchart of a power control method provided by another embodiment of the present disclosure. The method is applied to a network side. As shown in FIG. 3, the present disclosure provides a power control method including the steps of 301-302.

Step 301: receiving a power control parameter corresponding to a resource in an uplink beam management resource set used for an uplink beam management procedure.

In some embodiments of the present disclosure, the uplink beam management procedure may include an identical beam or a plurality of different beams being adopted by a user equipment.

Optionally, the above power control parameter is used for power control of resources in the uplink beam management resource set. For example, the above power control parameter may include, but is not limited to, one or more of an open-loop power control parameter set, a closed-loop power control parameter set and a transmission power.

It will be understood that the embodiments of the present disclosure may reasonably configure the above-described power control parameter according to actual conditions.

It will be understood that the embodiments of the present disclosure may configure only one power control parameter for all resources in the uplink beam management resource set, and may also configure a power control parameter for each resource in the uplink beam management resource set.

Step 302: sending a resource in the uplink beam management resource set according to a power control parameter corresponding to the resource in the uplink beam management resource set.

In the embodiments of the present disclosure, after the terminal receives the power control parameter, the terminal may send the resource in the resource set based on the power control parameter. For example, in a case that the power control parameter is the transmission power, the terminal may send, using the transmission power, the resource in the uplink beam management resource set used for the uplink beam management procedure; in a case that the power control parameter is the open-loop power control parameter set and/or the closed-loop power control parameter set, the terminal may calculate the transmission power according to the open-loop power control parameter set and/or the closed-loop power control parameter set, and further send, using the transmission power, the resource in the uplink beam management resource set used for the uplink beam management procedure.

Thus, the power control method according to some embodiments of the present disclosure receives the power control parameter corresponding to the resource in the uplink beam management resource set used for the uplink beam management procedure, and sends the resource in the uplink beam management resource set according to the power control parameter corresponding to the resource in the uplink beam management resource set. In this way, power control of resources in the uplink beam management resource set used for the uplink beam management procedure is realized, and a signaling overhead of the power control of uplink beam management resources used for the uplink beam management procedure can be controlled.

The reference beam set identifier described above may include one or more reference beam identifiers.

Optionally, power control parameters corresponding to respective resources in the uplink beam measurement resource set used for the same uplink beam measurement procedure are the same.

In the embodiments of the present disclosure, all resources in the beam management resource set used for the uplink beam management procedure may correspond to the common power control parameter. That is, all resources in the uplink beam management resource set used for the uplink beam management procedure correspond to the common power control parameter, so that the terminal sends all resources in the beam management resource set according to the common power control parameter. Optionally, in the embodiments of the present disclosure, each resource in the beam management resource set used for the uplink beam management procedure may also correspond to a corresponding power control parameter, and power control parameters corresponding to the resources are the same, so that the terminal can send each resource using the same transmission power and the network device may better evaluate the quality of the uplink beam of the terminal.

Optionally, sending the resource in the uplink beam management resource set according to the power control parameter corresponding to the resource in the uplink beam management resource set, includes: calculating a transmission power corresponding to the resource in the uplink beam management resource set, according to the power control parameter corresponding to the resource in the uplink beam management resource set, wherein, the power control parameter includes one or more of an open-loop power control parameter set, a closed-loop power control parameter set, a path loss value, and a reference beam set identifier; and sending the resource in the uplink beam management resource set using the transmission power corresponding to the resource in the uplink beam management resource set.

In the embodiments of the present disclosure, in a case that the power control parameter includes one or more of an open-loop power control parameter set, a closed-loop power control parameter set, a path loss value, and a reference beam set identifier, the terminal needs to calculate a transmission power corresponding to the resource in the resource set according to the power control parameter and further send respective resources in the resource set using the transmission power.

For example, in a case that the power control parameter is the open-loop power control parameter set and the closed-loop power control parameter set, the transmission power may be firstly calculated according to the open-loop power control parameter set and the closed-loop power control parameter set; in a case that the power control parameter is a path loss value, the transmission power may be calculated firstly according to the path loss value; in a case that the power control parameter is the reference beam set identifier, the transmission power may be firstly calculated according to the reference beam set identifier.

Optionally, in a case that the power control parameter includes the open-loop power control parameter set and/or the closed-loop power control parameter set, sending the resource in the uplink beam management resource set according to the power control parameter corresponding to the resource in the uplink beam management resource set, includes: obtaining the reference power control parameter, wherein, the reference power control parameter includes the power control parameter of a Physical Uplink Shared Channel (PUSCH) or a power control parameter of a Physical Random Access Channel (PRACH) or a power control parameter of a Physical Uplink Control Channel (PUCCH) or a power control parameter of a Sounding Reference Signal (SRS); determining the transmission power corresponding to the resource in the uplink beam management resource set according to a part of power control parameters in the open-loop power control parameter set and/or a part of power control parameters in the closed-loop power control parameter set corresponding to resources in the uplink beam management resource set and the reference power control parameter; sending the resource in the uplink beam management resource set using the transmission power corresponding to the resource in the uplink beam management resource set.

In the embodiments of the present disclosure, the terminal may calculate the transmission power in conjunction with the reference power control parameter and a part of power control parameters in the open loop-power control parameter set and/or a part of power control parameters in the closed-loop power control parameter set configured on a network device side. The reference power control parameter may include a power control parameter of the PUSCH or a power control parameter of the PRACH or a power control parameter of the PUCCH or a power control parameter of the SRS.

For example, the reference power control parameter described above may be configured according to a power control parameter of a PUSCH most recently sent, or a power control parameter of a PRACH most recently sent, or a power control parameter of a PUCCH most recently sent, or a power control parameter of the SRS most recently sent.

It should be noted that the reference power parameter may be one or more of power control parameters of a PUSCH, for example, the reference power parameter includes only a target reception power of the PUSCH.

Optionally, a part of power control parameters in the open-loop power control parameter set and/or a part of power control parameters in the closed-loop power control parameter set may be determined based on a reference power parameter configured at a terminal side. For example, in a case that the terminal side configures the target reception power, the network device side may configure one or more of remaining power control parameters other than the target reception power, for example, the path loss compensation factor, the power offset, and the like.

Embodiments of the present disclosure may reduce a control signaling overhead by referring to power control parameters of other channels or signals.

Optionally, obtaining the reference power control parameter includes obtaining a power control parameter of a current or historical PUSCH, or a power control parameter of a current or historical PRACH, or a power control parameter of a current or historical PUCCH, or a power control parameter of a current or historical Sounding Reference Signal (SRS) as the reference power control parameter.

In the embodiments of the present disclosure, the power control parameter of the current or historical PUSCH may be obtained as the reference power control parameter, or the power control parameter of the current or historical PRACH may be obtained as the reference power control parameter, or the power control parameter of the current or historical PUCCH may be obtained as the reference power control parameter, or the power control parameter of the current or historical Sounding Reference Signal (SRS) may be obtained as the reference power control parameter.

Optionally, the reference power control parameter is determined by a beam or a beam pair corresponding to a path loss value of a resource in the uplink beam management resource set, or, determined by a beam or a beam pair corresponding to one path loss value of path loss values of transmission beams or transmission beam pairs of at least two Channel State Information Reference Signal (CSI-RS) sets or at least two synchronization signal block sets, wherein an absolute value of a difference value between the one path loss value and the path loss value of the resource in the uplink beam management resource set is minimum among absolute values of difference values between the path loss values and the path loss value of the resource in the uplink beam management resource set.

For example, in a case that a terminal takes the maximum value between the path loss value “a” of the transmission beam or the transmission beam pair for a CSI-RS having an identifier “a” and the path loss value “b” of the transmission beam or the transmission beam pair for a CSI-RS having an identifier “b” as the path loss value corresponding to the resource in the uplink beam management resource set, and in a case that the path loss value “a” is greater than the path loss value “b”, then the path loss value corresponding to the resource in the uplink beam management resource set is the path loss value “a”, and the above reference power control parameter may be determined based on the downlink beam or the downlink beam pair used to calculate the path loss value “a”, i.e., the transmission beam or the transmission beam pair for the CSI-RS having the identifier “a”. In a case that the terminal takes a weighted average value of the path loss value “a” of the transmission beam or the transmission beam pair for a CSI-RS having the identifier “a” and the path loss value “b” of the transmission beam or the transmission beam pair for a CSI-RS having the identifier “b” as the path loss value corresponding to the resource in the uplink beam management resource set, and in a case that an absolute value of a difference value between the path loss value “a” and the weighted average value “c” is smaller than an absolute value of a difference value between the path loss value “b” and the weighted average value “c”, then the reference power control parameter may be determined according to the transmission beam or the transmission beam pair for the CSI-RS having the identifier “a”.

Optionally, before sending the resource in the uplink beam management resource set according to the power control parameter corresponding to the resource in the uplink beam management resource set, the method further includes: determining a path loss value corresponding to the resource in the uplink beam management resource set based on a path loss value of a transmission beam or a transmission beam pair of a Channel State Information Reference Signal (CSI-RS) set or a synchronization signal block set.

In the embodiments of the present disclosure, the path loss value corresponding to the resource in the uplink beam management resource set may be determined based on a path loss value of a transmission beam or a transmission beam pair of a CSI-RS set or a synchronization signal block set. For example, the maximum value of path loss values of transmission beams or transmission beam pairs of CSI-RS sets or synchronization signal block sets may be taken as the path loss value corresponding to the resource in the resource set. The minimum value of the path loss values of the transmission beams or the transmission beam pairs of the CSI-RS sets or the synchronization signal block sets may also be taken as the path loss value corresponding to the resource in the resource set.

Optionally, determining the path loss value corresponding to the resource in the uplink beam management resource set based on the path loss value of the transmission beam or the transmission beam pair of the Channel State Information Reference Signal (CSI-RS) set or the synchronization signal block set includes: determining the maximum value of the path loss values of transmission beams or transmission beam pairs of at least two CSI-RSs and/or at least two synchronization signal blocks as the path loss value corresponding to the resource in the uplink beam management resource set; or determining the minimum value of the path loss values of transmission beams or transmission beam pairs of at least two CSI-RSs and/or at least two synchronization signal blocks as the path loss value corresponding to the resource in the uplink beam management resource set; or determining an intermediate value among the path loss values of transmission beams or transmission beam pairs of at least two CSI-RSs and/or at least two synchronization signal blocks as the path loss value corresponding to the resource in the uplink beam management resource set; or determining a weighted average value of the path loss values of transmission beams or transmission beam pairs of at least two CSI-RSs and/or at least two synchronization signal blocks as the path loss value corresponding to the resource in the uplink beam management resource set.

Optionally, before determining the path loss value corresponding to the resource in the uplink beam management resource set based on the path loss value of the transmission beam or the transmission beam pair of the Channel State Information Reference Signal (CSI-RS) set or the synchronization signal block set, the method further includes: receiving a CSI-RS set or a synchronization signal block set configured by a network device, wherein the CSI-RS set or the synchronization signal block set is used for calculating the path loss value of the resource in the uplink beam management resource set; or receiving a measurement resource set configured by a network device; determining a channel state information reference signal set or a synchronization signal block set used for calculating a path loss value of the resource in the uplink beam management resource set, according to a Reference Signal Receiving Power (RSRP) or a Signal to Interference Plus Noise Ratio (SINR) of a measurement resource in the measurement resource set.

For example, the above synchronization signal block set may be Synchronization Signal (SS) block (i.e., Block) in a 5G system.

The RSRP may be a first-layer RSRP (L1-RSRP), or a third-layer RSRP (L3-RSRP).

Optionally, the terminal determines the CSI-RS set or the synchronization signal block set used to calculate the path loss value of the resource in the uplink beam measurement resource set, according to a Reference Signal Receiving Power (RSRP) or a Signal to Interference Plus Noise Ratio (SINR) of each measurement resource. For example, N measurement resources with relatively larger RSRPs or relatively larger SINRs may be obtained from M measurement resources and taken as a CSI-RS set or a synchronization signal block set for calculating the path loss value of the resource in the uplink beam management resource set, where M, N are all positive integers, M>=N.

(Technical Specification or Technical Protocol).

Optionally, the method further includes reporting a Reference Signal Receiving Power (RSRP) based on periodic or semi-persistent channel state information reference signals (CSI-RS) or periodic or semi-persistent synchronization signal blocks.

Thus, the network device may calculate the transmission power according to the RSRP reported based on the periodic or semi-persistent CSI-RSs or the periodic or semi-persistent synchronization signal blocks.
