[0034] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.
[0035] The power control parameter determination method of the present disclosure can be applied to... Figure 1 The wireless communication system shown. (See attached image) Figure 1 As shown, this wireless communication system includes network equipment and terminals. The terminals connect to the network equipment via wireless resources and transmit data.
[0036] Understandable, Figure 1 The wireless communication system shown is for illustrative purposes only. A wireless communication system may also include other network devices, such as core network equipment, wireless relay equipment, and wireless backhaul equipment. Figure 1 Not shown in the diagram. This disclosure does not limit the number of network devices and terminals included in the wireless communication system.
[0037] It is further understood that the wireless communication system of this disclosure is a network providing wireless communication functionality. The wireless communication system can employ different communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA), 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 carrier sense multiple access with collision avoidance. Based on factors such as capacity, speed, and latency, networks can be categorized as 2G networks, 3G networks, 4G networks, or future evolution networks, such as 5G networks. 5G networks can also be referred to as New Radio (NR). For ease of description, this disclosure may sometimes simply refer to the wireless communication network as a network.
[0038] Furthermore, the network device involved in this disclosure can also be referred to as a wireless access network device. This wireless access network device can be: a base station, an evolved Node B (eBY), a home base station, an access point (AP) in a Wireless Fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (TP), or a transmission and reception point (TRP), etc. It can also be a gNB in an NR system, or a component or part of a base station. It should be understood that the specific technology and specific device form used in the embodiments of this disclosure are not limited. In this disclosure, the network device can provide communication coverage for a specific geographical area and can communicate with terminals located within that coverage area (cell). Furthermore, when it is a vehicle-to-everything (V2X) communication system, the network device can also be an in-vehicle device.
[0039] Furthermore, the terminal involved in this disclosure can also be referred to as a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., which is a device that provides voice and / or data connectivity to a user. For example, the terminal can be a handheld device with wireless connectivity, an in-vehicle device, etc. Currently, some examples of terminals include: smartphones, customer premise equipment (CPE), pocket personal computers (PPCs), handheld computers, personal digital assistants (PDAs), laptops, tablets, wearable devices, or in-vehicle devices, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device can also be an in-vehicle device. It should be understood that the embodiments of this disclosure do not limit the specific technology or specific device form adopted by the terminal.
[0040] The application of multiple TRPs / panels in base stations primarily aims to improve coverage at cell edges and provide a more balanced quality of service within the service area. This involves collaborative data transmission among multiple TRPs / panels using different methods. From a network architecture perspective, deploying the network with a large number of distributed access points and centralized baseband processing is more conducive to providing a balanced user experience rate and significantly reducing latency and signaling overhead during handover. Utilizing collaboration between multiple TRPs or panels to transmit / receive data from multiple angles and beams can better overcome various obstruction / blocking effects, ensuring robust link connections and making it suitable for URLLC services to improve transmission quality and meet reliability requirements.
[0041] In some embodiments of this disclosure, transmission enhancement of the Physical Downlink Shared Channel (PDSCH) can be achieved based on the application of multi-point cooperative transmission technology between downlink multiple TRPs / PANELs. Since data transmission involves scheduling feedback between uplink and downlink channels, enhancing only the downlink data channel is insufficient to guarantee service performance in URLLC research. Therefore, it is necessary to further enhance the Physical Downlink Control Channel (PDCCH), Physical Uplink Control Channel (PUCCH), and data channels such as the Physical Uplink Shared Channel (PUSCH).
[0042] Uplink PUSCH transmission is transmitted to the TRP direction of multiple base stations. In some embodiments of this disclosure, cooperative transmission under TDM transmission mode is standardized. Different repetitions of the same information on PUSCH are sent to different TRPs of the base station at different time-division multiplexing through different transmission occupancy (TO) in the time domain. This method has relatively low requirements for terminal capabilities, does not require the ability to transmit beams simultaneously, and has a large transmission delay.
[0043] For uplink, the actual channels traversed by PUSCH channels facing different TRPs may have very different spatial characteristics. Therefore, it is assumed that the QCL-D of PUSCH channels in different transmission directions are different.
[0044] The above implementation scheme does not consider multiple-transmission-reception-point (M-TRP) scenarios, and the uplink is transmitted to a single-transmission-reception-point (S-TRP). Some embodiments of this disclosure enhance the uplink transmission of M-TRP under S-DCI, transmitting the uplink PUSCH to the TRP directions of multiple base stations, and standardizing the cooperative transmission under TDM transmission mode. By time-division multiplexing the transmission of the same information on the PUSCH to different TRPs of the base station at different transmission occupancy (TO) times, this method has relatively low requirements for terminal capabilities. Each TO only needs to transmit the PUSCH in one TRP direction, so it does not require the ability to transmit beams simultaneously, but the transmission delay is relatively large.
[0045] In some embodiments of this disclosure, it is desirable to achieve simultaneous cooperative transmission from multiple terminal panels to multiple base stations' TRPs to increase transmission reliability and throughput, while effectively reducing transmission latency under multiple TRPs. However, this requires the terminal to have the ability to transmit multiple beams simultaneously. PUSCH transmission can be based on multi-panel or multi-TRP transmission scheduled by a single Physical Downlink Control Channel (PDCCH), i.e., S-DCI, such as... Figure 2 As shown. The UE communicates with the base station's TPR1 via panel1, for example, receiving the first precoding matrix indicator (TPMI) TPMI1 sent by TPR1, and sending one or more transport layer-related information to TRP1. It also communicates with the base station's TPR2 via panel2, for example, receiving the second precoding matrix indicator (TPMI2) sent by TPR2, and sending one or more transport layer-related information to TRP2. Multi-panel or multi-TRP transmission can also be scheduled based on different PDCCHs, i.e., multiple-downlink control information (M-DCI), such as... Figure 3 As shown in the diagram, the UE communicates with the base station's TPR1 through panel1, for example, receiving PDCCH1 sent by TRP1 and sending PUSCH1 to TRP1. It also communicates with the base station's TPR2 through panel2, for example, receiving PDCCH2 sent by TRP2 and sending PUSCH2 to TRP2.
[0046] Terminals are typically configured with multiple physical panels, and the capabilities of different panels may vary. For example, they may have different numbers of Sounding Reference Signal (SRS) ports and support different maximum data transmission layers; one panel might support a maximum of Layer 2 transmission, while another supports a maximum of Layer 4. The network scheduler determines whether the terminal is suitable for simultaneous uplink transmission across multiple panels. If the terminal is suitable for simultaneous uplink transmission across multiple panels and is scheduled accordingly, the network will directly or indirectly indicate the relevant transmission parameters, including the terminal's specific beamforming information, the number of data layers used for transmission, the allocation of Demodulation Reference Signal (DMRS) ports, and precoding indication information.
[0047] In some embodiments of this disclosure, Simultaneous Transmission from Multiple Panels (STxMP) supports transmission schemes for S-DCI-based PUSCHs including Space Division Multiplexing (SDM) and Single Frequency Network (SFN) schemes. In the SDM scheme, different parts of a PUSCH Transport Block (TB) are transmitted to two different TRPs on the same time-frequency resource through their respective corresponding DMRS ports or port combinations allocated on different panels. Different panels, different TRPs, or different TOs are associated with different TCI states, i.e., beams. In the SFN scheme, a PUSCH TB is transmitted to two different TRPs on the same time-frequency resource through the same DMRS ports or port combinations allocated on different panels. Different panels, different TRPs, or different TOs are associated with different TCI states, i.e., beams.
[0048] In 5G systems, there are data services with different priorities, latency requirements, or reliability requirements. For example, URLLC services have extremely high requirements for latency and reliability, while Enhanced Mobile Broadband (eMBB) services have relatively lower requirements. URLLC typically uses shorter transmission intervals for scheduling, and its bursty and random nature results in fragmented resource distribution and low resource utilization. Therefore, multiplexing with eMBB transmissions can be considered to improve resource utilization. Unlike downlink transmissions, a UE does not know whether its uplink data transmission resources overlap with those of other UEs transmitting services of different priorities. To ensure the reliability of URLLC transmissions, an Open-Loop Power Control Parameter Set Indication (OLPC) field can be introduced into the Downlink Control Information (DCI) to indicate the power boosting function for the scheduling PUSCH. It can also introduce a new Radio Resource Control (RRC) parameter P0-PUSCH-Set to indicate power control. Each Sounding Reference Signal resource indicator (SRI) corresponds to an open-loop power control P0-PUSCH-Set parameter, which is indicated through the Open-loop power control parameter set indication field.
[0049] During uplink STxMP transmission, situations still arise where different terminals within the system send eMBB and URLLC services, and the network prioritizes ensuring the transmission reliability of URLLC services. In M-TRP-based PUSCH enhancements, the conflict conditions between URLLC services transmitted via M-TRP and eMBB services generally differ across different TRPs, meaning the interference levels received by the two TRPs at the base station vary. If the different interference levels of different TRPs within the M-TRP are not distinguished, the adjustment mechanism may cause terminals to fail to adapt their transmission power well to the interference conditions, increasing interference to other users and degrading system performance.
[0050] like Figure 4As shown, if UE1 sends URLLC service data to TRP1 and TRP2 on PUSCH, and UE2 sends EMBB service data to TRP1 on PUSCH, the interference situation received by TRP1 and TRP2 is different. Therefore, it is necessary to optimize the transmission power of the terminal under different interference conditions.
[0051] In view of this, the present disclosure provides a power control parameter determination method. When it is determined that the terminal is performing STxMP transmission of PUSCH, one or more OLPC indication fields are configured for the terminal, which enhances the power boosting mechanism of OLPC and can more reasonably handle the conflicts of different service terminals during STxMP transmission, thereby optimizing the performance of the terminal and the system.
[0052] In this embodiment of the disclosure, when it is determined that the terminal is performing multi-panel simultaneous transmission STxMP transmission on the Physical Uplink Shared Channel (PUSCH), one or more OLPC indication fields are configured for the terminal.
[0053] Figure 5 This is a flowchart illustrating a power control parameter determination method according to an exemplary embodiment, such as... Figure 5 As shown, this method is executed by a network device and includes the following steps.
[0054] In step S11, it is determined that the terminal performs STxMP transmission of PUSCH, and one or more OLPC indication fields are configured for the terminal.
[0055] In some embodiments, the network device configures the number of OLPC indication fields for the terminal via higher-layer signaling.
[0056] In one implementation, the network device determines whether the terminal supports configuring multiple OLPC indication fields based on the capability information reported by the terminal, and determines the number of OLPC indication fields to configure for the terminal based on the capability information.
[0057] In another implementation, the network device configures the number of OLPC indication fields for the terminal based on protocol specifications or default rules.
[0058] In this embodiment of the disclosure, the network device can determine the transmission scenario of the terminal. When it is determined that the current transmission scenario of the terminal is to configure and schedule PUSCH for STxMP transmission, that is, when it is determined that the terminal is performing STxMP transmission of PUSCH, since the terminal may cause conflicts with other terminals with different services when sending services in this scenario, the network device can configure one or more OLPC indication fields for the terminal to enhance the OLPC control method and avoid the above-mentioned conflicts.
[0059] By employing the technical solution of this disclosure embodiment, one or more OLPC indication fields are configured for the terminal when it is determined that the terminal is performing STxMP transmission of PUSCH, thereby enhancing the power boosting mechanism of OLPC. This can more reasonably handle the conflicts between different service terminals during STxMP transmission and optimize the performance of the terminal and the system.
[0060] In this embodiment of the disclosure, one or more OLPC indication fields are used to determine the open-loop power control parameters corresponding to different PUSCH TOs for different TCI states or different TRPs, and the PUSCH TOs for different TCI states or different TRPs are associated with different sets of Probe Reference Signals (SRS) resources.
[0061] The association between a TCI state and an SRS resource set can be given by the SRS resource set indicator field. For example, when the SRS resource set indicator field corresponding to a code point indicates "10", TCI state1 can be associated with SRS resource set 1, corresponding to the first TO of the PUSCH; TCI state2 can be associated with SRS resource set 2, corresponding to the second TO of the PUSCH. The reverse is also true.
[0062] In some embodiments, different PUSCH TOs corresponding to different TCI states or different TRPs are associated with power parameter sets, each power parameter set includes multiple power control configurations, and each power control configuration may include one or more open-loop power control parameters.
[0063] For example, the first PUSCH TO corresponding to the first TCI state or the first TRP is associated with the first power parameter set, such as Uplink_PowerControl, and the second PUSCH TO corresponding to the second TCI state or the second TRP is associated with the second power parameter set, such as P0-PUSCH-AlphaSet.
[0064] In one implementation, the OLPC indication field is used to indicate that the power control configuration corresponding to the PUSCH TO corresponding to the TCI state or TRP is determined based on the SRI index or default rules from the set of power parameters associated with the PUSCH TO corresponding to the TCI state or TRP, and the corresponding open-loop power control parameters are obtained from the power control configuration.
[0065] For example, the first OLPC indication field is used to indicate that the first PUSCHTO power parameter set corresponding to the first TCI state or the first TRP is the first power parameter set. The first power parameter set includes three power configurations, namely power control configuration 0, power control configuration 1 and power control configuration 2. When the SRI index corresponding to the first TCI state or the first TRP exists and the first SRI index value is 1, then the power control configuration 1 in the first open-loop power control parameters corresponding to the first PUSCHTO of the first TCI state or the first TRP is determined based on the first SRI index value. Then the terminal determines the first open-loop power control parameters from the power control configuration 1. The second OLPC indication field is used to indicate the PUSCHTO2 associated power parameter set 1 corresponding to TCI state2 or TRP2. The power control parameter set 1 includes three power control configurations: power control configuration 0, power control configuration 1, and power control configuration 2. If the index of TCI state is TCI state2 and TCI state2 corresponds to power control configuration 2, then the open-loop power control parameter corresponding to PUSCHTO2 corresponding to TCI state2 or TRP2 is determined from power control configuration 2 in power parameter set 1.
[0066] In this embodiment of the disclosure, by configuring one or more OLPC indication fields, the open-loop power control parameters corresponding to different PUSCH transmission times TO for different TCI states or different TRPs are determined, which more reasonably handles the conflicts of different service terminals when transmitting STxMP, and optimizes the performance of terminals and systems.
[0067] In a power control parameter determination method provided in this disclosure embodiment, a single OLPC indication field is configured for the terminal.
[0068] In some embodiments, when a network device configures an OLPC indication field for a terminal, an OLPC indication field is used simultaneously to determine the open-loop power control parameters corresponding to different PUSCH TOs for different TCI states or different TRPs.
[0069] In one implementation, the network device configures a power control parameter set for the terminal. This power control parameter set includes a first power control parameter set (P0-PUSCH-AlphaSet) and a second power control parameter set (P0-PUSCH-Set). That is, the network device configures both a first power control parameter set and a second power control parameter set for the terminal. Then, an OLPC indication field is simultaneously used to determine the open-loop power control parameters corresponding to different PUSCH TOs for different TCI states or different TRPs. The open-loop power control parameters corresponding to different PUSCH TOs for different TCI states or different TRPs are located in the same power control parameter set. If the DCI includes different SRIs corresponding to different PUSCH TOs, the open-loop power control parameters corresponding to different PUSCH TOs for different TCI states or different TRPs are determined from the control parameter set based on the different SRI index values. If all or some of the different SRIs corresponding to different PUSCH TOs in the DCI are missing, the open-loop power control parameters corresponding to the PUSCH TOs for which no SRIs are missing are obtained based on the default rules, that is, the different or the same open-loop power control parameters corresponding to different PUSCH TOs for different TCI states or different TRPs are determined from the control parameter set.
[0070] For example, the network device configures a first power control parameter set and a second power control parameter set for the terminal, and the OLPC indication field indicates the first power control parameter set. If the DCI includes different SRIs corresponding to different PUSCH TOs, the OLPC indication field is used to determine the power control configurations corresponding to different PUSCH TOs for different TCI states or different TRPs based on the SRI indices of different TCI states or different TRPs from the first power control parameter set, and to determine the corresponding open-loop power control parameters from their respective power configurations. If all or some of the different SRIs corresponding to different PUSCH TOs in the DCI are absent, the OLPC indication field is used to determine the power control configurations corresponding to PUSCH TOs without SRIs based on default rules from the first power control parameter set, and to determine the corresponding open-loop power control parameters from their respective power control configurations. In this case, the open-loop power control parameters corresponding to different PUSCH TOs for different TCI states or different TRPs may be the same or different.
[0071] In another implementation, the network device configures a power control parameter set for each TRP. This power parameter set includes a first power control parameter set and a second power control parameter set. That is, the network device configures a first power control parameter set and / or a second power control parameter set for each TRP. Then, an OLPC indication field is used to indicate how to determine the open-loop power control parameters for different TCI states or different PUSCH TOs corresponding to different TRPs from the power control parameter set corresponding to each TRP.
[0072] In this embodiment of the disclosure, when the network device configures an OLPC indication field for the terminal, the OLPC indication field is used to determine the different or the same open-loop power control parameters corresponding to different PUSCH TOs for different TCI states or different TRPs, thereby enabling the determination of open-loop power control parameters for multiple TCI states or multiple TRPs through an OLPC indication field.
[0073] In a power control parameter determination method provided in this embodiment, multiple OLPC indication fields are configured for the terminal.
[0074] Among them, different OLPC indication fields in multiple OLPC indication fields are used to determine the open-loop power control parameters corresponding to different PUSCH TO for different TCI states or different TRPs.
[0075] In some embodiments, different OLPC indication fields in multiple OLPC indication fields are used to determine the power control configurations corresponding to different PUSCH TOs for different TCI states or different TRPs, and different PUSCH TOs for different TCI states or different TRPs use the corresponding open-loop power control parameters in their respective power control processes.
[0076] In this embodiment of the disclosure, the network device can configure multiple OLPC indication fields for the terminal. Different OLPC indication fields can be used to determine the corresponding open-loop power control parameters corresponding to different PUSCH TO for different TCI states or different TRPs.
[0077] In this embodiment of the disclosure, the OLPC indication field corresponding to the TO of PUSCH associated with different SRS resource sets can be independently indicated. In one example, multiple OLPC indication fields can be configured to be carried in the downlink control information (DCI), and the number of bits and code points corresponding to each OLPC indication field may be the same or different. That is, by extending the existing DCI indication fields, multiple OLPC indication fields can be configured in the DCI indication fields to achieve control over PUSCH power enhancement for transmission to different TRPs.
[0078] In this embodiment of the disclosure, the network device independently configures the number of bits and code points for each of the multiple OLPC indication fields.
[0079] In some embodiments, the number of bits in each OLPC indication field is configured independently by RRC signaling, and the code point in each OLPC indication field is indicated independently by DCI.
[0080] For example, the network device configures the number of bits of the first OLPC indication field to 1 based on RRC signaling, and the DCI indicates that the code point of the first OLPC indication field is 0; the network device configures the number of bits of the second OLPC indication field to 2 based on RRC signaling, and the DCI indicates that the code point of the second OLPC indication field is 00.
[0081] In this embodiment of the disclosure, when the DCI includes an SRI, the OLPC indication field of the TO corresponding to the PUSCH associated with different SRS resource sets can also be used to indicate the power parameter set corresponding to the open-loop power control parameters of different TCI states or different TRPs associated with different SRI / SRS resource sets through the OLPC indication field.
[0082] In this embodiment of the disclosure, the terminal may or may not use the unified TCI state framework to indicate beam information. When the terminal does not use the unified TCI state framework to indicate beam information, it is necessary to configure default parameter sets PO-PUSCH-AlphaSet and / or P0-PUSCH-Set for the terminal.
[0083] When the terminal does not use a unified TCI state framework to indicate beam information, and the DCI includes SRIs, the open-loop power control parameters can be determined based on this default parameter set. In one example, in response to the DCI including multiple SRIs and the terminal not using a unified TCI state to indicate beams, and at least one OLPC indication field in the multiple OLPC indication fields has 0 bits, the open-loop power control parameters corresponding to the PUSCH TO of the TCI state or TRP associated with at least one OLPC indication field are determined based on predefined rules. These predefined rules can be: determining the first or second value in the default parameter set PO-PUSCH-AlphaSet as the open-loop power control parameters that can correspond to the first or second TCI state or different PUSCH TOs corresponding to different TRPs; or determining the first or second value in the default parameter set P0-PUSCH-Set as the open-loop power control parameters that can correspond to the first or second TCI state or different PUSCH TOs corresponding to different TRPs.
[0084] In this embodiment of the disclosure, the open-loop power control parameters corresponding to the first or second TCI state or different PUSCH TOs for different TRPs can be determined in the PO-PUSCH-AlphaSet using the sri_PUSCH_PowerControlId of SRI1 or SRI2. Alternatively, the open-loop power control parameters corresponding to the first or second TCI state or different PUSCH TOs for different TRPs can also be determined using different P0-PUSCH-Sets of SRI1 or SRI2.
[0085] In this embodiment of the disclosure, the code point corresponding to at least one OLPC indication field among a plurality of OLPC indication fields is designated as the first code point. The open-loop power control parameters corresponding to the PUSCH TO of the TCI state or TRP associated with at least one OLPC indication field can be determined based on the first power parameter set indicated by the SRI and the SRI index, wherein the first power parameter sets indicated by different SRIs may be the same or different. The first power parameter set may be a PO-PUSCH-AlphaSet.
[0086] For example, the power control configuration corresponding to different PUSCH TOs for the first or second TCI state / TRP is determined in PO-PUSCH-AlphaSet by using SRI_PUSCH_PowerControlId of SRI1 or SRI2, and the open-loop power control parameters are obtained from their respective power control configurations.
[0087] In this embodiment of the disclosure, the code point of each OLPC indication field in response to multiple OLPC indication fields is a second code point. The open-loop power control parameters corresponding to different PUSCH TOs for at least one OLPC indication field associated with a TCI state or TRP are determined based on the second power parameter set indicated by the SRI and the SRI index, wherein the second power parameter sets indicated by different SRIs may be the same or different. The second power parameter set may be a P0-PUSCH-Set.
[0088] For example, the power control configuration corresponding to different PUSCH TOs for the first or second TCI state / TRP is determined in the P0-PUSCH-Set by SRI1 or SRI2, and the open-loop power control parameters are obtained from their respective power control configurations.
[0089] When the terminal does not use a unified TCI state to indicate beam information, and the DCI includes SRIs, the open-loop power control parameters can also be determined based on the open-loop power control parameter set and the corresponding SRI index. In one example, in response to the DCI including multiple SRIs and the terminal not using a unified TCI state, and multiple OLPC indication fields having at least one OLPC indication field with 1 bit, the open-loop power control parameters corresponding to the PUSCH TO of the TCI state or TRP associated with at least one OLPC indication field are determined based on the associated power parameter set and the corresponding SRI index.
[0090] In this embodiment of the disclosure, when the DCI does not include the SRI, the open-loop power control parameters of the application corresponding to each panel are determined by 1 bit or 2 bits in multiple OLPC indication fields. At this time, the multiple OLPC indication fields can determine the open-loop power control parameters corresponding to different PUSCH TOs for different TCI states or different TRPs based on default rules.
[0091] In this embodiment of the disclosure, in response to the absence of SRI in the DCI and the fact that at least one OLPC indication field in the plurality of OLPC indication fields has 1 bit or 2 bits, the open-loop power control parameter corresponding to the PUSCHTO of the TCI state or TRP associated with at least one OLPC indication field is determined based on the code point of at least one OLPC indication field.
[0092] In this embodiment of the disclosure, in response to the code point of at least one OLPC indication field being a third code point, the open-loop power control parameters corresponding to the PUSCH TO of the TCI state or TRP associated with at least one OLPC indication field are determined based on a first power parameter set associated with at least one OLPC indication field. The first power parameter set may be a PO-PUSCH-AlphaSet. For example, when the code point of the OLPC indication field is 0 or 00, the open-loop power control parameters corresponding to the PUSCH TO of the corresponding TCI state or TRP can be determined through the PO-PUSCH-AlphaSet.
[0093] In this embodiment of the disclosure, in response to the code point of at least one OLPC indication field being a fourth code point, the open-loop power control parameters corresponding to the PUSCH TO of the TCI state or TRP associated with the at least one OLPC indication field are determined based on the first value in a second power parameter set associated with the at least one OLPC indication field. The second power parameter set may be a P0-PUSCH-Set. For example, when the code point of the OLPC indication field is 1 or 01, the open-loop power control parameters corresponding to the PUSCH TO of the TCI state or TRP can be determined by the first value of the corresponding P0-PUSCH-Set.
[0094] In this embodiment of the disclosure, in response to the code point of at least one OLPC indication field being the fifth code point, the open-loop power control parameter corresponding to PUSCH TO of the TCI state or TRP associated with at least one OLPC indication field is determined based on the second value in the second power parameter set associated with at least one OLPC indication field. The second power parameter set can be a P0-PUSCH-Set. For example, when the code point of the OLPC indication field is 10 or 11, the open-loop power control parameter corresponding to PUSCH TO of the TCI state or TRP can be determined by the second value of the corresponding P0-PUSCH-Set.
[0095] In the above embodiments, the network device can independently configure the number of bits and code points of multiple OLPC indication fields.
[0096] In some embodiments, the network device configures the OLPC indication field for the terminal via the higher-layer signaling p0-PUSCH-SetList. When the network device does not configure the higher-layer parameter p0-PUSCH-SetList, the OLPC indication field is 0 bits, that is, the OLPC indication field does not exist, and the terminal obtains P0 from P0-PUSCH-AlphaSet according to the mechanism specified in the prior protocol. When the network device configures the higher-layer parameter p0-PUSCH-SetList, the network device can configure 1 bit or 2 bits for the OLPC indication field via higher-layer signaling.
[0097] In some embodiments, for each OLPC indication field, the terminal can determine the open-loop power parameters of the TCI state or TRP associated with the OLPC indication field based on higher-layer parameters, the SRI indication field, and the OLPC code point, as shown in Table 1:
[0098] Table 1
[0099]
[0100] This disclosure also provides a method for configuring OLPC indication fields, wherein a network device receives capability information sent by a terminal and configures one or more OLPC indication fields for the terminal based on the terminal's capability information.
[0101] In some embodiments, the network device determines, based on capability information, that the terminal does not support configuring multiple OLPC indication fields, and configures one OLPC indication field for the terminal.
[0102] In some embodiments, the network device determines, based on capability information, that the terminal supports configuring multiple OLPC indication fields, and configures one OLPC indication field for the terminal.
[0103] In some embodiments, the network device determines, based on capability information, that the terminal supports configuring multiple OLPC indication fields, and configures multiple OLPC indication fields for the terminal.
[0104] In this embodiment of the disclosure, the network device can configure one or more OLPC indication fields for the terminal based on the terminal's capability information, thereby more reasonably handling the conflicts of different service terminals when transmitting STxMP, and optimizing the performance of the terminal and the system.
[0105] Figure 6 This is a flowchart illustrating a method for determining power control parameters according to an exemplary embodiment, such as... Figure 6 As shown, this method is executed by the terminal and includes the following steps.
[0106] In step S21, based on the configuration information, one or more OLPC indication fields are determined under the STxMP transmission of PUSCH.
[0107] In some embodiments, the configuration information is determined by the network device based on the capability information reported by the terminal and sent to the terminal. In other embodiments, the configuration information is determined by the terminal based on a protocol. The terminal can determine one or more OLPC indication fields configured by the network device or specified by the protocol based on the configuration information.
[0108] In this embodiment of the disclosure, when the current transmission scenario of the terminal is to configure and schedule PUSCH for STxMP transmission, that is, when the terminal performs STxMP transmission of PUSCH, since the terminal may cause conflicts with other terminals with different services when sending services in this scenario, the terminal determines one or more OLPC indication fields based on the configuration information, thereby enhancing the control of OLPC and avoiding the above-mentioned conflicts.
[0109] By adopting the technical solution of this disclosure embodiment, when the terminal performs STxMP transmission of PUSCH, it determines one or more OLPC indication fields, which enhances the power boosting mechanism of OLPC, and can more reasonably handle the conflicts of different service terminals during STxMP transmission, thereby optimizing the performance of the terminal and the system.
[0110] In this embodiment of the present disclosure, the terminal determines the open-loop power control parameters corresponding to different PUSCH transmission times TO for different TCI states or different TRPs based on one or more OLPC indication fields, and the PUSCH TO for different TCI states or different TRPs are associated with different SRS resource sets.
[0111] The association between a TCI state and an SRS resource set can be given by the SRS resource set indicator field. For example, when the SRS resource set indicator field corresponding to a code point indicates "10", TCI state1 can be associated with SRS resource set 1, corresponding to the first TO of the PUSCH; TCI state2 can be associated with SRS resource set 2, corresponding to the second TO of the PUSCH. The reverse is also true.
[0112] In some embodiments, different PUSCH TOs corresponding to different TCI states or different TRPs are associated with power parameter sets, each power parameter set including multiple power control configurations, and each power control configuration including one or more open-loop power control parameters.
[0113] For example, the first PUSCH TO corresponding to the first TCI state or the first TRP is associated with the first power parameter set, such as Uplink_PowerControl, and the second PUSCH TO corresponding to the second TCI state or the second TRP is associated with the second power parameter set, such as P0-PUSCH-AlphaSet.
[0114] In one implementation, the OLPC indication field is used to indicate the power control configuration corresponding to the PUSCH TO associated with the TCI state or TRP, determined based on the SRI index from the set of power parameters associated with the PUSCH TO corresponding to the TCI state or TRP, and the terminal obtains the open-loop power control parameters from the power control configuration.
[0115] For example, the first OLPC indication field is used to indicate that the power parameter set associated with the first PUSCH TO corresponding to the first TCI state or the first TRP is a first power parameter set. The first power parameter set includes power control configuration 1, power control configuration 2, and power control configuration 3. The SRI index corresponding to the first TCI state or the first TRP is a first SRI index. Based on the first SRI index, it is determined that the first open-loop power control parameter corresponding to the first PUSCH TO corresponding to the first TCI state or the first TRP is located in power control configuration 2. Then, the terminal determines the first open-loop power control parameter from power control configuration 2. The second OLPC indication field is used to indicate that the power parameter set 1 associated with PUSCH TO2 corresponding to TCI state2 or TRP2 is a power parameter set 1. The power control parameter set 1 includes three power control configurations: power control configuration 0, power control configuration 1, and power control configuration 2. If the index of TCI state is TCI state2, and TCI state2 corresponds to power control configuration 2, then the open-loop power control parameter corresponding to PUSCH TO2 corresponding to TCI state2 or TRP2 is determined from power control configuration 2 in power parameter set 1.
[0116] In this embodiment of the disclosure, by configuring one or more OLPC indication fields, the open-loop power control parameters corresponding to different PUSCH transmission times TO for different TCI states or different TRPs are determined, which more reasonably handles the conflicts of different service terminals when transmitting STxMP, and optimizes the performance of terminals and systems.
[0117] Figure 7 This is a flowchart illustrating a method for determining an OLPC indication field according to an exemplary embodiment, such as... Figure 7 As shown, the method includes the following steps.
[0118] In step S31, the terminal determines an OLPC indication field based on the configuration information.
[0119] In a power control parameter determination method provided in this embodiment, the terminal simultaneously determines the open-loop power control parameters corresponding to different PUSCH TOs for different TCI states or different TRPs based on an OLPC indication field.
[0120] In one implementation, the network device configures a power control parameter set for the terminal. This power control parameter set includes a first power control parameter set (P0-PUSCH-AlphaSet) and a second power control parameter set (P0-PUSCH-Set). That is, the network device configures both a first power control parameter set and a second power control parameter set for the terminal. The terminal then simultaneously determines the open-loop power control parameters corresponding to different PUSCH TOs for different TCI states or different TRPs based on an OLPC indication field. The open-loop power control parameters corresponding to different PUSCH TOs for different TCI states or different TRPs are located within the same power control parameter set. If the DCI includes different SRIs corresponding to different PUSCH TOs, the terminal determines the open-loop power control parameters corresponding to different PUSCH TOs for different TCI states or different TRPs from the power control parameter set based on the different SRI index values. If all or some of the different SRIs corresponding to different PUSCH TOs in the DCI are missing, the open-loop power control parameters corresponding to the PUSCH TOs for which no SRIs are missing are obtained based on the default rules, that is, the different or the same open-loop power control parameters corresponding to different PUSCH TOs for different TCI states or different TRPs are determined from the control parameter set.
[0121] For example, the network device configures a first power control parameter set and a second power control parameter set for the terminal, with the OLPC indication field indicating the first power control parameter set. If the DCI includes different SRIs corresponding to different PUSCH TOs, the terminal determines the power control configuration corresponding to different PUSCH TOs for different TCI states or different TRPs based on the SRI index of different TCI states or different TRPs from the first power control parameter set using the OLPC indication field, and determines the corresponding open-loop power control parameters from each of the corresponding power configurations. If all or some of the different SRIs corresponding to different PUSCH TOs in the DCI are absent, the terminal determines the corresponding power control configuration based on the default rules from the first power control parameter set using the OLPC indication field, and determines the corresponding open-loop power control parameters from each of the power control configurations. In this case, the open-loop power control parameters corresponding to different PUSCH TOs for different TCI states or different TRPs may be the same or different.
[0122] In another implementation, the network device configures a power control parameter set for each TRP. This power control parameter set includes a first power control parameter set and a second power control parameter set. That is, the network device configures a first power control parameter set and a second power control parameter set for each TRP. The terminal then determines the open-loop power control parameters corresponding to different TCI states or different PUSCH TOs for different TRPs from the power control parameter set corresponding to each TRP based on an OLPC indication field.
[0123] In this embodiment of the disclosure, when the network device configures an OLPC indication field for the terminal, the terminal can determine different or the same open-loop power control parameters corresponding to different PUSCH TOs for different TCI states or different TRPs based on an OLPC indication field, thereby enabling the determination of open-loop power control parameters for multiple TCI states or multiple TRPs through an OLPC indication field.
[0124] Figure 8 This is a flowchart illustrating a power control parameter determination method according to an exemplary embodiment, such as... Figure 8 As shown, the method includes the following steps.
[0125] In step S41, the terminal determines multiple OLPC indication fields based on the configuration information.
[0126] In step S42, the open-loop power control parameters corresponding to different PUSCH TOs for different TCI states or different TRPs are determined based on different OLPC indication domains in multiple OLPC indication domains.
[0127] In some embodiments, different OLPC indication fields in multiple OLPC indication fields are used to determine the power control configurations corresponding to different PUSCH TOs for different TCI states or different TRPs, and the open-loop power control parameters corresponding to different PUSCH TOs for different TCI states or different TRPs are located in their respective power controls.
[0128] In this embodiment of the present disclosure, the terminal determines multiple OLPC indication fields based on configuration information. Different OLPC indication fields can be used to determine the open-loop power control parameters corresponding to different PUSCH TO for different TCI states or different TRPs.
[0129] In this embodiment of the disclosure, the OLPC corresponding to the TO of a PUSCH associated with different SRS resource sets can be independently indicated. In one example, multiple OLPC indication fields can be configured to be carried in the downlink control information (DCI), and the number of bits and code point information corresponding to each OLPC indication field in the multiple OLPC indication fields are the same. That is, by extending the existing DCI indication fields, multiple OLPC indication fields can be configured in the DCI indication fields to achieve control over the PUSCH power boost sent to different TRPs.
[0130] In this embodiment of the disclosure, the network device independently configures the number of bits and code points for each of the multiple OLPC indication fields.
[0131] In some embodiments, the number of bits in each OLPC indication field is configured independently by RRC signaling, and the code point in each OLPC indication field is indicated independently by DCI.
[0132] For example, the network device configures the number of bits of the first OLPC indication field to 1 based on RRC signaling, and the DCI indicates that the code point of the first OLPC indication field is 0; the network device configures the number of bits of the second OLPC indication field to 2 based on RRC signaling, and the DCI indicates that the code point of the second OLPC indication field is 00.
[0133] In this embodiment of the disclosure, when the DCI includes an SRI, the terminal can determine the OLPC indication field of the PUSCH TO associated with different SRS resource sets based on the SRI. In one example, the DCI includes multiple SRIs, and the terminal determines the set of power parameters corresponding to the open-loop power control parameters of different TCI states or different TRPs associated with different SRIs / SRS resource sets based on the different OLPC indication fields in the multiple OLPC indication fields.
[0134] In this embodiment of the disclosure, when the terminal does not use the unified TCI state framework to indicate beam information, it is necessary to configure the default parameter set PO-PUSCH-AlphaSet and / or P0-PUSCH-Set for the terminal.
[0135] When the terminal does not use a unified TCI state framework to indicate beam information, and the DCI includes SRIs, the open-loop power control parameters can be determined based on this default parameter set. In one example, in response to the DCI including multiple SRIs, the terminal not using a unified TCI state, and multiple OLPC indication fields having 0 bits, the terminal determines the open-loop power control parameters corresponding to different PUSCH TOs for different TCI states or different TRPs based on predefined rules.
[0136] In some embodiments, the predefined rule may be that the terminal determines the first or second value in the default parameter set PO-PUSCH-AlphaSet as the open-loop power control parameter corresponding to the first or second TCI state or different PUSCH TO corresponding to different TRPs, or the terminal determines the first or second value in the default parameter set P0-PUSCH-Set as the open-loop power control parameter corresponding to the first or second TCI state or different PUSCH TO corresponding to different TRPs.
[0137] In this embodiment of the disclosure, the open-loop power control parameters corresponding to the first or second TCI state or different PUSCH TOs for different TRPs can be determined in the PO-PUSCH-AlphaSet using the sri_PUSCH_PowerControlId of SRI1 or SRI2. Alternatively, the open-loop power control parameters corresponding to the first or second TCI state or different PUSCH TOs for different TRPs can also be determined using different P0-PUSCH-Sets of SRI1 or SRI2.
[0138] In this embodiment of the disclosure, the code point of at least one OLPC indication field of a plurality of OLPC indication fields is determined as the first code point. Based on the first code point of at least one OLPC indication field and the SRI index, the terminal determines the open-loop power control parameters corresponding to the PUSCH TO of at least one OLPC indication field associated with the TCI state or TRP from the first power parameter set corresponding to the PUSCH TO of the TCI state or TRP indicated by the SRI.
[0139] In some embodiments, the first set of power parameters indicated by different SRIs may be the same or different.
[0140] In some embodiments, the first power parameter set may be PO-PUSCH-AlphaSet.
[0141] In this embodiment of the disclosure, the code point of each of the multiple OLPC indication fields is determined as the second code point. Based on the second code point of at least one OLPC indication field and the SRI index, the terminal determines the power control configuration corresponding to the PUSCH TO of at least one OLPC indication field associated with the TCI state or TRP from the second power parameter set corresponding to the PUSCH TO of the TCI state or TRP indicated by the SRI, and obtains the open-loop power control parameters from the respective corresponding power control configurations.
[0142] In some embodiments, the set of second power parameters indicated by different SRIs may be the same or different.
[0143] In some embodiments, the second power parameter set may be a P0-PUSCH-Set.
[0144] When the terminal does not use a unified TCI state framework to indicate beam information, and the DCI includes SRIs, the open-loop power control parameters can still be determined based on the open-loop power control parameter set and the corresponding SRI index. In one example, in response to the DCI including multiple SRIs and the terminal not using a unified TCI state, and the number of bits in multiple OLPC indication fields being 1 bit, the open-loop power control parameters corresponding to different PUSCH TOs for different TCI states or different TRPs are determined by their respective associated power parameter sets and corresponding SRI indices. Furthermore, the power control configurations corresponding to different PUSCH TOs for different TCI states or different TRPs can be determined through different P0-PUSCH-Sets of SRI1 or SRI2, and the open-loop power control parameters can be obtained from their respective power control configurations.
[0145] In this embodiment of the disclosure, when the DCI does not include the SRI, the open-loop power control parameters of the application corresponding to each panel are determined by 1 bit or 2 bits in multiple OLPC indication fields. At this time, the multiple OLPC indication fields can determine the open-loop power control parameters used by different PUSCH TOs corresponding to different TCI states or different TRPs based on default rules.
[0146] In this embodiment of the disclosure, it is determined that the DCI does not include SRI, and at least one OLPC indication field in the plurality of OLPC indication fields has a bit count of 1 bit or 2 bits. The terminal determines the open-loop power control parameters corresponding to the PUSCH TO of the TCI state or TRP associated with at least one OLPC indication field based on the code point of at least one OLPC indication field.
[0147] In this embodiment of the disclosure, at least one code point of the OLPC indication field is determined as the third code point, and the terminal determines the open-loop power control parameter corresponding to the PUSCH TO of the TCIstate or TRP associated with at least one OLPC indication field from the first power parameter set based on the third code point of the at least one OLPC indication field.
[0148] In some embodiments, the first power parameter set may be a PO-PUSCH-AlphaSet. For example, when the code point of the OLPC indication field is 0 or 00, the terminal can determine the open-loop power control parameters corresponding to different PUSCH TOs for different TCI states or different TRPs through the PO-PUSCH-AlphaSet. Furthermore, the terminal can determine the open-loop power control parameters corresponding to the first or second TCI state or different PUSCH TOs for different TRPs in the PO-PUSCH-AlphaSet using the sri_PUSCH_PowerControlId of SRI1 or SRI2.
[0149] In this embodiment of the disclosure, at least one code point of an OLPC indication field is determined as the fourth code point. Based on the fourth code point of at least one OLPC indication field, the terminal determines the open-loop power control parameter corresponding to PUSCHTO of the TCI state or TRP associated with at least one OLPC indication field as the first value in the second power parameter set corresponding to PUSCHTO of the TCI state or TRP.
[0150] In some embodiments, the second power parameter set may be a P0-PUSCH-Set. For example, when the code point of the OLPC indication field is 1 or 01, the terminal can determine the open-loop power control parameters corresponding to different PUSCH TOs for different TCI states or different TRPs by using the first value of different P0-PUSCH-Sets.
[0151] In this embodiment of the disclosure, at least one code point of an OLPC indication field is determined as the fifth code point. Based on the fifth code point of at least one OLPC indication field, the terminal determines the open-loop power control parameter corresponding to PUSCHTO of the TCI state or TRP associated with at least one OLPC indication field as the second value in the second power parameter set corresponding to PUSCHTO of the TCI state or TRP.
[0152] In some embodiments, the second power parameter set may be a P0-PUSCH-Set. For example, when the code point of the OLPC indication field is 10 or 11, the terminal can determine the open-loop power control parameters corresponding to different PUSCH TO for different TCI states or different TRPs by using the second value of different P0-PUSCH-Sets.
[0153] In a power control parameter determination method provided in this embodiment, the terminal sends capability information to enable the network device to determine whether the terminal supports configuring one or more OLPC indication fields, thereby enabling the network device to configure one or more OLPC indication fields for the terminal based on the capability information.
[0154] In some embodiments, capability information is used to indicate that the terminal does not support configuring multiple OLPC indication fields, or capability information is used to indicate that the terminal supports configuring multiple OLPC indication fields, and configuration information is used to configure a single OLPC indication field for the terminal, and the terminal determines the single OLPC indication field based on the configuration information.
[0155] In other embodiments, capability information is used to indicate that the terminal supports configuring multiple OLPC indication fields, configuration information is used to configure multiple OLPC indication fields for the terminal, and the terminal determines multiple OLPC indication fields based on the configuration information.
[0156] In this embodiment of the disclosure, the network device can configure one or more OLPC indication fields for the terminal based on the terminal's capability information, thereby more reasonably handling the conflicts of different service terminals when transmitting STxMP, and optimizing the performance of the terminal and the system.
[0157] In the process of determining power control parameters through interaction between the terminal and the network device, the terminal possesses the corresponding functions and implementations of the power control parameter determination method executed by the terminal in the above embodiments, and the network device possesses the corresponding functions and implementations of the power control parameter determination method executed by the network device in the above embodiments.

[0161] Figure 9 This is a block diagram illustrating a power control parameter determination device according to an exemplary embodiment. (Refer to...) Figure 9 The device 100 includes a processing module 101.
[0162] The processing module 101 is used to determine whether the terminal is performing multi-panel simultaneous transmission (STxMP) of the Physical Uplink Shared Channel (PUSCH) and to configure one or more OLPC indication fields for the terminal.
[0163] In one embodiment, one or more OLPC indication fields are used to determine the open-loop power control parameters corresponding to different PUSCH transmission timings TO for different Transmission Configuration Indication States (TCIstate) or different Transmission Receiver Points (TRPs). The PUSCH TO for different TCI states or different TRPs are associated with different Sounding Reference Signal (SRS) resource sets.
[0164] In one embodiment, the processing module 101 is used to configure an OLPC indication field for the terminal.
[0165] In one embodiment, the OLPC indication field is simultaneously used to determine the open-loop power control parameters corresponding to different PUSCH TOs for different TCI states or different TRPs.
[0166] In one embodiment, the processing module 101 is configured to configure multiple OLPC indication fields for the terminal, wherein different OLPC indication fields are used to determine the open-loop power control parameters corresponding to different PUSCH TO for different TCI states or different TRPs.
[0167] In one embodiment, multiple OLPC indication fields are carried in downlink control information (DCI), and the number of bits and code points corresponding to each OLPC indication field may be the same or different.
[0168] In one embodiment, the DCI also includes multiple Channel Sounding Reference Signal Resource Indicators (SRIs) and the terminal does not use a unified TCI state indicator beam. Multiple OLPC indicator fields are used to indicate the power parameter sets corresponding to the open-loop power control parameters of different PUSCH TOs corresponding to different TCI states or different TRPs. Different PUSCH TOs corresponding to different TCI states or different TRPs are associated with different SRI / SRS resource sets.
[0169] In one implementation, in response to the DCI including multiple SRIs and the terminal not using a unified TCI state indicator beam, and at least one OLPC indicator field having 0 bits, the open-loop power control parameters corresponding to the PUSCH TO of the TCI state or TRP associated with at least one OLPC indicator field are determined based on predefined rules.
[0170] In one embodiment, at least one of the multiple OLPC indication fields has 1 bit. The at least one OLPC field is used to indicate the open-loop power control parameters corresponding to the PUSCH TO of the associated TCI state or TRP, which are determined based on the associated power parameter set and the corresponding SRI index.
[0171] In one embodiment, the code point of at least one OLPC indication field is a first code point, and the open-loop power control parameters corresponding to the PUSCH TO of the TCI state or TRP associated with the at least one OLPC indication field are determined based on the first power parameter set indicated by SRI and the SRI index, wherein the first power parameter sets of different SRI indications are the same or different.
[0172] In one embodiment, the code point of at least one OLPC indication field is a second code point, and the open-loop power control parameters corresponding to the PUSCH TO of the TCI state or TRP associated with at least one OLPC indication field are determined based on the second power parameter set indicated by SRI and the SRI index, wherein the second power parameter sets indicated by different SRIs may be the same or different.
[0173] In one embodiment, in response to the absence of SRI in DCI, at least one of the plurality of OLPC indication fields has 1 bit or 2 bits, and the at least one OLPC indication field is used to indicate the open-loop power control parameters corresponding to the PUSCH TO of the associated TCI state or TRP, which are determined based on the code points of the at least one OLPC indication field.
[0174] In one embodiment, the code point of at least one OLPC indication field is a third code point, and the open-loop power control parameters corresponding to the PUSCH TO of the TCI state or TRP associated with at least one OLPC indication field are determined from a first power parameter set.
[0175] In one embodiment, the code point of at least one OLPC indication field is a fourth code point, and the open-loop power control parameter corresponding to the PUSCH TO of the TCI state or TRP associated with the at least one OLPC indication field corresponds to the first value in the second power parameter set.
[0176] In one embodiment, the code point of at least one OLPC indication field is the fifth code point, and the open-loop power control parameter corresponding to the TCI state associated with at least one OLPC indication field or the PUSCH TO corresponding to different TRPs corresponds to the second value in the second power parameter set.
