Description

Communication method, device and storage medium

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on February 8, 2024, with application number 202410177013.X and application name “A communication method, device and storage medium”. The entire contents of the above application are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a communication method, device and storage medium. Background Art

[0003] In mobile communication systems, uplink and downlink data transmission methods can be categorized into time division duplex (TDD), frequency division duplex (FDD), and full duplex (FD) modes. In FD scenarios, subband non-overlapping full duplex (SBFD) achieves full duplex on the base station side by dividing a single carrier into non-overlapping uplink and downlink subbands, transmitting and receiving data separately on these subbands. This means that network equipment, such as base stations (gNBs or gNodeBs), supports full duplex mode, allowing simultaneous co-frequency transmission and transmission. Alternatively, network equipment supports SBFD mode, allowing uplink and downlink transmission to occur on different subbands within the SBFD symbol area.

[0004] Since multiple subbands may be simultaneously transmitting and receiving within a single carrier in a full-duplex mode scenario, additional interference is introduced. Among them, additional interference includes cross-link interference (CLI), for example, the downlink signal from the neighboring base station will interfere with the reception of the uplink signal for the serving base station, and for example, the downlink signal from the serving base station will cause self-interference to the reception of the uplink signal for the serving base station; for example, the uplink signal from the neighboring terminal device will interfere with the reception of the downlink signal for the target terminal device. In order to cope with the additional interference in full-duplex mode, the power on specific resources needs to be precisely controlled to suppress or better resist the above-mentioned additional interference, otherwise it may lead to erroneous reception of the transmitted signal.

[0083] Illustrative embodiments of the present application include, but are not limited to, a communication method, an electronic device, and a storage medium.

[0084] The technical solution provided in this application can be applied to various communication systems including scenarios with two working modes, wherein the two working modes include a first working mode and a second working mode, and the first working mode and the second working mode can be two working modes of a network device, respectively. The term "working mode" herein can also be replaced by "operation mode".

[0085] Optionally, the first working mode may be a non-full-duplex mode, and the second working mode may be a full-duplex mode. In various communication systems in duplex networking scenarios, full-duplex networking is adopted on the basis of existing communication systems, 5G NR systems, future evolution systems, or multiple communication convergence systems, etc. A variety of application scenarios may be included, and these scenarios may include but are not limited to: communication scenarios between UEs, communication scenarios between network devices, and communication scenarios between network devices and UEs. The technical solutions provided in the embodiments of the present application can also be applied to scenarios such as communication between UEs and UEs in a 5G communication system, or communication between network devices and network devices.

[0086] The following describes a communication method and device proposed in an embodiment of the present application, taking the first working mode and the second working mode as an example, respectively, a non-full-duplex mode.

[0087] To meet the challenges of wireless broadband technology and maintain the leading edge of 3GPP networks, the 3GPP standards group has developed a next-generation mobile communications network architecture, known as the 5G network architecture. This architecture not only supports 3GPP-defined wireless technologies (such as LTE) accessing the 5G core network (5GC), but also supports non-3GPP access technologies accessing the 5GC through the non-3GPP interworking function (N3IWF), the trusted non-3GPP gateway function (TNGF), the trusted WLAN interworking function (TWIF), or the next-generation packet data gateway (NG-PDG). The core network functions are divided into user plane function (UPF) and control plane function (CPF). The UPF is primarily responsible for packet forwarding, quality of service (QoS) control, and billing information statistics. CPF is mainly responsible for user registration and authentication, mobility management, and sending data packet forwarding policies and QoS control policies to UPF. It can be further divided into access and mobility management function (AMF) and session management function (SMF).

[0088] Core network equipment includes, for example, a mobility management entity (MME), a broadcast multicast service center (BMSC), etc., or may also include corresponding functional entities in the 5G system, such as core network control plane (CP) or user plane (UP) network functions, such as SMF, AMF, etc. The core network control plane can also be understood as a core network control plane function (CPF) entity.

[0089] The technical solution provided in the embodiment of the present application can be applied to the system architecture shown in Figure 1. The functions of the user equipment and each network entity are as described below.

[0090] Radio access network (RAN): A network composed of multiple 5G-RAN nodes that implements wireless physical layer functions, resource scheduling and wireless resource management, wireless access control, and mobility management. 5G-RAN is connected to the UPF via the user plane interface N3 to transmit data from terminal devices. 5G-RAN establishes a control plane signaling connection with the AMF via the control plane interface N2 to implement functions such as radio access bearer control. RAN can be any device with wireless transceiver capabilities, including but not limited to 5G base stations (5G node base, gNB), evolutionary node base (eNB), wireless access points (WiFi AP), world interoperability for microwave access base stations (WiMAX BS), transmission receiving points (TRP), wireless relay nodes, wireless backhaul nodes, etc.

[0091] The access network device (i.e., the network device of the access network) in the embodiment of the present application can also be a device for communicating with a terminal device. The access network device can be a base station (base transceiver station, BTS) in a global system of mobile communication (GSM) system or code division multiple access (CDMA), or a base station (nodeB, NB) in a wideband code division multiple access (WCDMA) system, or an evolutionary node base (eNB) in an LTE system, or a wireless controller in a cloud radio access network (CRAN) scenario, or the access network device can be a relay station, an access point, a vehicle-mounted device, a wearable device, and an access network device in a future 5G network or an access network device in a future evolved PLMN network, etc., and the embodiment of the present application is not limited.

[0092] In NR, the functions of the base station are divided into two parts, called centralized unit (CU)-distributed unit (DU) separation. From the perspective of the protocol stack, the CU includes the radio resource control (RRC) layer and the packet data convergence protocol (PDCP) layer of the LTE base station, and the DU includes the radio link control (RLC) layer, the media access control (MAC) layer and the physical (PHY) layer of the LTE base station. In ordinary 5G base station deployments, the CU and DU can be physically connected through optical fiber, and logically there is a specially defined F1 interface for communication between the CU and DU. From a functional perspective, the CU is mainly responsible for radio resource control and configuration, cross-cell mobility management, bearer management, etc. The DU is mainly responsible for scheduling, physical signal generation and transmission.

[0093] Among them, the above-mentioned base stations can be macro base stations, micro base stations, pico base stations, small stations, relay stations, balloon stations, etc.

[0094] SMF: Mainly responsible for the control plane functions of terminal device session management, including selection and control of user plane functions (UPF), Internet protocol (IP) address allocation, session QoS management, and obtaining policy and charging control (PCC) policies (from PCF).

[0095] UPF: As the anchor point for protocol data unit (PDU) session connections, it is responsible for filtering data packets for terminal devices, data transmission / forwarding, rate control, generating billing information, etc., and providing connections to the data network (DN).

[0096] PCF: Provides configuration policy information for terminal devices and policy information for controlling terminal devices to network control plane elements (such as SMF); generates terminal device access policies and QoS flow control policies.

[0097] AF: interacts with network elements in the core network to provide some services. For example, it interacts with PCF to perform service policy control, interacts with NEF to obtain some network capability information or provide some application information to the network, and provides some data network access point information to PCF to generate routing information for corresponding data services.

[0098] In the embodiments of the present application, the terminal device is wirelessly connected to the RAN device, and the RAN network element is wirelessly or wiredly connected to the 5GC device. The 5GC device and the RAN network element can be independent and distinct physical devices, or the functions of the 5GC device and the logical functions of the RAN network element can be integrated into the same physical device, or a single physical device can integrate some of the functions of the 5GC device and some of the functions of the RAN network element. The terminal device can be fixed or mobile.

[0099] 5GC equipment mainly includes the above-mentioned PCF network elements, SMF network elements and UPF network elements.

[0100] It should be noted that the aforementioned "network element" may also be referred to as an entity, device, apparatus, or module, etc., and this application does not specifically limit this. Furthermore, in this application, for ease of understanding and explanation, the term "network element" is omitted in some descriptions. For example, an NEF network element is referred to as NEF. In this case, the "NEF" should be understood as an NEF network element or NEF entity. The following descriptions of identical or similar situations are omitted.

[0101] It should be noted that the naming of each network element included in Figure 1 is only a name, and the name does not limit the function of the network element itself. In 5G networks and other future networks, the above-mentioned network elements may also have other names, and the embodiments of this application do not specifically limit this. For example, in a 6G network, some or all of the above-mentioned network elements may continue to use the terminology used in 5G, or may have other names, etc., which are uniformly explained here and will not be repeated below.

[0102] It should be noted that the network elements in Figure 1 do not have to exist simultaneously, and the network elements required can be determined according to needs. The connection relationship between the network elements in Figure 1 is not unique and can be adjusted according to needs.

[0103] It is understandable that the above-mentioned network elements or functions can be network elements in hardware devices, software functions running on dedicated hardware, or virtualized functions instantiated on a platform (for example, a cloud platform).

[0104] In order to facilitate understanding of the communication method of the embodiment of the present application, the technical problems to be solved by the embodiment of the present application are analyzed and explained below.

[0105] As mentioned above, in a FD scenario, subband non-overlapping full duplex (SBFD) can achieve full duplex on the base station side by dividing non-overlapping uplink / downlink subbands within a single carrier and receiving and transmitting data separately on the subbands.

[0106] In the SBFD scenario, network equipment, such as base stations (gNB, gNodeB), supports full-duplex capability and can send and receive data simultaneously on the same frequency; or the network equipment supports SBFD mode. In the SBFD symbol area, uplink and downlink can exist at any time in different sub-bands, that is, the symbols in the SBFD symbol area can exist as uplink symbols and downlink symbols at the same time. Taking Figures 2A and 2B as an example, a single carrier is divided into multiple sub-bands, where the SBFD symbol area includes the uplink symbol U corresponding to the uplink sub-band. SBFD And the downlink symbol D corresponding to the downlink subband SBFD According to FIG2A and FIG2B, the uplink symbol U SBFD and down symbol D SBFD Taking Figure 2C as an example, a single carrier is divided into multiple sub-bands, where the SBFD symbol area includes the uplink symbol U corresponding to the uplink sub-band. SBFD and the downlink symbols D corresponding to the multiple downlink subbands SBFD_1 、D SBFD_2 As shown in Figure 2C, the uplink symbol U SBFD and multiple descending symbols D SBFD_1、D SBFD_2 Can exist at the same time.

[0107] In the SBFD scenario, one SBFD mode is that the terminal device, such as the user equipment (UE), does not have full-duplex capability and uses TDD to communicate with the network device. That is, the symbols of a single UE in the SBFD symbol area can only be either uplink symbols or downlink symbols. It can be understood that in this SBFD mode, since the UE does not support full-duplex mode, the uplink signal sent by the UE to the network device will not be subject to self-interference. At the same time, the uplink signal sent by the UE to the network device may be interfered with by the downlink signal from the network device. In addition, the uplink signal sent by the UE to the network device may be interfered with by the downlink signal from the neighboring network device of the network device, and the uplink signal sent by the UE to the network device may also interfere with the downlink signal for the neighboring UE. These interferences are CLI.

[0108] In the SBFD scenario, another SBFD mode is that the terminal device, such as the UE, has full-duplex capability. That is, the symbols of a single UE in the SBFD symbol area may include uplink symbols and downlink symbols. It can be understood that in this SBFD mode, the uplink signal sent by the UE to the network device will interfere with the reception of the downlink signal for the UE. At the same time, the uplink signal sent by the UE to the network device may be interfered with by the downlink signal from the network device. In addition, the uplink signal sent by the UE to the network device may be interfered with by the downlink signal from the network device's neighboring network devices, and the uplink signal sent by the UE to the network device may also interfere with the reception of the downlink signal for the neighboring UE. These interferences are CLI.

[0109] It should be noted that the full-duplex mode in the embodiments of the present application is not limited to SBFD. In other embodiments, other full-duplex modes such as simultaneous full-duplex in the same frequency may also be adopted, and the present application does not limit this.

[0110] The following describes the CLI in the scenario of the embodiment of the present application in conjunction with FIG3 .

[0111] Referring to Figure 3 , in the communication system shown in Figure 3 , network equipment includes a first base station 210 and a second base station 220, and UEs include a first terminal 211, a second terminal 212, a third terminal 221, and a fourth terminal 222. First base station 210 is located near second base station 220. First terminal 211 and second terminal 212 belong to the cell managed by adjacent base station 210, while third terminal 221 and fourth terminal 222 belong to the cell managed by second base station 220. Second terminal 212, third terminal 221, and fourth terminal 222 are located near each other.

[0112] In full-duplex mode, the base station can simultaneously configure the downlink (DL) sub-band and the uplink (UL) sub-band on one carrier. That is, on the same carrier, at the same time, some terminals can perform uplink transmission, and some terminals can perform downlink transmission; or on the same carrier, at the same time, a single terminal can perform uplink transmission and downlink transmission.

[0113] In the first embodiment, the downlink signal from the second base station 220 to the third terminal 221 generates adjacent channel interference to the uplink signal from the first terminal 211 received by the first base station 210 .

[0114] In the second embodiment, a downlink signal from the first base station 210 to the second terminal 212 generates co-channel interference to an uplink signal from the first terminal 211 received by the first base station 210 .

[0115] In the third embodiment, the uplink signal from the first terminal 211 to the first base station 210 generates CLI for the downlink signal received by the third terminal 221 from the second base station 220. Furthermore, the uplink signal from the fourth terminal 222 to the second base station 220 also generates adjacent channel interference for the downlink signal received by the third terminal 221 from the second base station 220.

[0116] For the uplink signal sent from the first terminal 211 to the first base station 210, in the case of CLI caused by other links, such as in the scenarios of the first and second embodiments above, in order to ensure the transmission quality of the transmitted signal, it is necessary to appropriately increase the uplink transmit power. In addition, in the case of CLI that may cause other links, such as in the scenario of the third embodiment above, in order to reduce the interference caused to other links, it is necessary to appropriately reduce the uplink transmit power. Therefore, in full-duplex mode, the power on specific resources needs to be precisely controlled to minimize the impact of CLI on the system.

[0117] Based on the above problems, the present application provides a communication method, in which a network device configures two uplink power control parameter sets for a terminal device, namely a first uplink power control (UL PC) parameter set for full-duplex mode and a second UL PC parameter set for non-full-duplex mode. The terminal device can determine in real time whether the working mode of the network device is full-duplex mode to select the corresponding power control parameters, thereby realizing uplink transmission power control in a full-duplex networking scenario.

[0118] In one embodiment, a terminal device may control the transmit power of an uplink signal based on whether the network device is in full-duplex mode. For example, a network device with full-duplex capability may send a configuration message or indication information to the terminal device to assist the terminal device in determining the operating mode corresponding to the signal to be transmitted. Specifically, the terminal device may determine the operating mode of the network device corresponding to the time-frequency position of the signal to be transmitted, so that the terminal device can control the transmit power of the uplink signal based on the determined operating mode.

[0119] For example, in an optional embodiment, the network device sends the working mode configuration information of the full-duplex mode to the terminal device. The terminal device can determine whether the signal to be sent corresponds to the full-duplex mode based on the working mode configuration information of the full-duplex mode. The working mode configuration information includes time-frequency domain position information and uplink and downlink information, for example, including the working mode of the uplink signal at each time domain position and frequency domain position. If the terminal device determines that the signal to be sent corresponds to the full-duplex mode according to the working mode configuration information, the uplink transmission power of the signal to be sent is determined by the first UL PC parameter set for the full-duplex mode; if the terminal device determines that the signal to be sent corresponds to the non-full-duplex mode according to the working mode configuration information, the uplink transmission power of the signal to be sent is determined by the second UL PC parameter set for the non-full-duplex mode.

[0120] In an optional embodiment, the network device may send power control indication information to the terminal device. For example, the power control indication information is carried in downlink control information (DCI), and one or more fields in the DCI are used to indicate whether to use the first UL PC parameter set or the second UL PC parameter set. The terminal device may determine which parameter set to use, the first UL PC parameter set for full-duplex mode or the second UL PC parameter set for non-full-duplex mode, based on the power control indication information. If it is determined to use the first UL PC parameter set, the first UL PC parameter set is used to determine the uplink transmit power of the signal to be sent; if it is determined to use the second UL PC parameter set, the second UL PC parameter set is used to determine the uplink transmit power of the signal to be sent. It should be noted that the above-mentioned indication of the working mode through DCI is only an example. In other embodiments, other configuration information or indication messages may also be used to indicate the working mode to the terminal device, and this application is not limited to this.

[0121] In an optional implementation, the terminal device measures the measurement quantity of a specific subband and determines whether it corresponds to full-duplex mode based on the measurement result. Optionally, if the measurement result is less than or equal to the measurement threshold, it is considered that the signal to be transmitted does not correspond to full-duplex mode, and the first UL PC parameter set for full-duplex mode is used to determine the uplink transmit power of the signal to be transmitted; if the measurement result is greater than the measurement threshold, it is considered that the signal to be transmitted corresponds to full-duplex mode, and the second UL PC parameter set for non-full-duplex mode is used to determine the uplink transmit power of the signal to be transmitted. As an example, the specific subband is the subband of the signal to be transmitted. If the measurement result is less than or equal to the measurement threshold, it means that the subband is not subject to downlink interference from the adjacent subband, and it is considered to correspond to non-full-duplex mode. Otherwise, it is considered to correspond to full-duplex mode. The measurement parameters may include at least one of synchronization signal reference signal received power (SS-RSRP), channel state reference signal received power (CSI-RSRP), sounding reference signal reference signal received power (SRS-RSRP), received signal strength indication (RSSI), and cross-link interference received signal strength indicator (CLI-RSSI). It should be noted that the above-mentioned specific subband is the subband of the signal to be transmitted, which is only an example, and what kind of working mode is considered to correspond to according to the measurement results is also only an example. In other embodiments, other subbands can also be measured, and the working mode can be determined according to the measurement results in other ways. This application is not limited to this.

[0122] As an example, the operating mode configuration information can enable the terminal device to know which operating mode the signal to be sent corresponds to, so that different parameters are used according to different operating modes to calculate the uplink transmit power. Accordingly, an embodiment of the present application provides a communication method applied to a terminal device in the communication system shown in Figure 1. Optionally, the terminal device can be a UE. As shown in Figure 4, the method may include S401-S403:

[0123] S401: The terminal device receives the working mode configuration information sent by the network device.

[0124] In an optional embodiment, the operating mode configuration information includes time-frequency resource configuration information of the operating mode, and the time-frequency resource configuration information of the operating mode is used to instruct the terminal device to determine the operating mode corresponding to the time-frequency resource of the uplink signal to be sent based on the time-frequency resource configuration information. For example, the time-frequency resource configuration information includes time-frequency domain position information and uplink and downlink information. Specifically, for each time-frequency domain unit of data transmission, there may be different uplink and downlink information.

[0125] It can be understood that the working mode in the embodiment of the present application is the working mode of the network device, including non-full-duplex mode and full-duplex mode.

[0126] As an example, the time domain location is divided into a single time slot based on the time domain unit, such as time slot 1 and time slot 2; the frequency domain location is divided into a single frequency domain resource based on the frequency domain unit, such as frequency domain resource 1 and frequency domain resource 2. The uplink and downlink information of different frequency bands in the same slot can be both uplink, both downlink, or both uplink and downlink respectively. For example, the uplink and downlink information of frequency domain resource 1 in time slot 1 is uplink, and the uplink and downlink information of frequency domain resource 2 in time slot 1 is downlink, indicating that the uplink and downlink information of different frequency bands in the same slot are both uplink and downlink respectively; due to the simultaneous existence of uplink and downlink subbands, time slot 1 corresponds to full-duplex mode.

[0127] Optionally, each terminal device may correspond to a frequency domain resource in the time-frequency resource configuration information, and each frequency domain resource in the time-frequency resource configuration information corresponds to multiple time slots. Therefore, the time-frequency resource configuration information configures the uplink and downlink information of each time slot for the terminal device. For example, the uplink and downlink information of the frequency domain resource corresponding to the terminal device in each time slot may include a silent state, uplink or downlink. It can be understood that the silent state means that no uplink or downlink transmission is performed at the corresponding position. For example, frequency domain resource 1 represents the subband used for communication between the network device and the terminal device, and the uplink and downlink information of frequency domain resource 1 in time slot 1 is static; the uplink and downlink information of frequency domain resource 1 in time slot 2 is uplink.

[0128] Optionally, the time domain unit includes any one of a superframe, a system frame, a subframe, a time slot, a micro-time slot, a mini-time slot, and an orthogonal frequency division multiplexing OFDM symbol, or includes any combination of a superframe, a system frame, a subframe, a time slot, a mini-time slot, and an orthogonal frequency division multiplexing OFDM symbol. This application does not limit the time domain unit.

[0129] Optionally, the frequency domain unit includes any one of a control channel element (CCE), a control resource set (CORSET), a physical resource block (PRB), a band width partial (BWP), or a subcarrier. This application does not limit the frequency domain unit.

[0130] In an optional implementation, the working mode configuration information includes working mode indication information, and the working mode indication information is used to instruct the terminal device to determine the working mode corresponding to the signal to be sent.

[0131] Optionally, the operating mode indication information includes non-full-duplex mode indication information and full-duplex mode indication information, wherein the non-full-duplex mode indication information is used to indicate that the signal to be sent by the terminal device corresponds to the non-full-duplex mode; and the full-duplex mode indication information is used to indicate that the signal to be sent by the terminal device corresponds to the full-duplex mode.

[0132] S402: The terminal device receives a first UL PC parameter set and a second UL PC parameter set sent by the network device.

[0133] The first UL PC parameter set corresponds to a non-full-duplex mode, and the second UL PC parameter set corresponds to a full-duplex mode.

[0134] It can be understood that for uplink signals corresponding to non-full-duplex mode, the terminal device calculates its uplink transmit power according to the first UL PC parameter set; and for uplink signals corresponding to full-duplex mode, the terminal device calculates its uplink transmit power according to the second UL PC parameter set.

[0135] Optionally, the first UL PC parameter set or the second UL PC parameter set includes parameters of at least one uplink channel or uplink signal. The uplink channel includes at least one of a physical uplink shared channel (PUSCH), a physical uplink control channel (PUCCH), and a physical random access channel (PRACH), and the uplink signal includes a sounding reference signal (SRS).

[0136] In an optional embodiment, the parameter types included in the first UL PC parameter set and the second UL PC parameter set are consistent.

[0137] For example, for each parameter type, the value of the parameter type in the first UL PC parameter set is lower than the value of the parameter type in the second UL PC parameter set. That is, the first UL PC parameter set is configured to calculate a lower uplink transmit power than the second UL PC parameter set.

[0138] For another example, for each parameter type, the value of the parameter type in the first UL PC parameter set is higher than the value of the parameter type in the second UL PC parameter set. That is, the first UL PC parameter set is configured to have a higher uplink transmit power than the second UL PC parameter set.

[0139] In an optional embodiment, the first UL PC parameter set and the second UL PC parameter set include a first parameter type that is positively correlated with the uplink transmit power and a second parameter type that is negatively correlated with the uplink transmit power. It is understood that a larger parameter of the first parameter type results in a larger calculated uplink transmit power; and a larger parameter of the second parameter type results in a smaller calculated uplink transmit power.

[0140] For example, for each first parameter type, the value of the parameter type in the first UL PC parameter set is lower than the value of the parameter type in the second UL PC parameter set; for each second parameter type, the value of the parameter type in the first UL PC parameter set is higher than the value of the parameter type in the second UL PC parameter set. That is, the first UL PC parameter set is configured to have a lower uplink transmit power calculated than the second UL PC parameter set.

[0141] For another example, for each first parameter type, the value of the parameter type in the first UL PC parameter set is higher than the value of the parameter type in the second UL PC parameter set; for each second parameter type, the value of the parameter type in the first UL PC parameter set is lower than the value of the parameter type in the second UL PC parameter set. That is, the first UL PC parameter set is configured to have a higher uplink transmit power calculated than the second UL PC parameter set.

[0142] The following introduces optional implementation methods of the PUSCH parameters included in the first UL PC parameter set or the second UL PC parameter set.

[0143] The 3rd Generation Partnership Project (3GPP) defines the PUSCH power control formula in Section 7.1.1 of TS 38.331 to calculate the uplink transmit power of a terminal device transmitting PUSCH information in BWP b, cell c, carrier f, and subframe i. The specific formula is as follows:

[0147] Optionally, in the first UL PC parameter set, the parameter value of each PUSCH is lower than the value of the same type of parameter in the second UL PC parameter set. O_PUSCH，b，f，c (j) Compared to P in the second UL PC parameter set O_PUSCH，b，f，c (j) takes a lower value.

[0148] Optionally, in the first UL PC parameter set, the parameter value of each PUSCH is higher than the value of the same type of parameter in the second UL PC parameter set. O_PUSCH，b，f，c(j) Compared to P in the second UL PC parameter set O_PUSCH，b，f，c (j) takes a higher value.

[0151] Optionally, the PUCCH parameters included in the first UL PC parameter set or the second UL PC parameter set include P O_PUCCH，b，f，c (q u ).

[0158] P PRACH，b，f，c (i) = min{P CMAX，f，c (i), P PRACH，target，f，c +PL b，f，c}

[0159] Optionally, the PRACH parameters included in the first UL PC parameter set or the second UL PC parameter set include PREAMBLE_RECEIVED_TARGET_POWER.

[0160] For the specific content of PREAMBLE_RECEIVED_TARGET_POWER, please refer to the definition in 3GPP TS 38.321 protocol, which is not repeated here.

[0161] Optionally, the PRACH parameters included in the first UL PC parameter set or the second UL PC parameter set include preambleReceivedTargetPower and powerRampingStep.

O_SRS，b，f，c (q s ) and α SRS，b，f，c (q s ) can refer to the definition of 3GPP in TS 38.213 protocol, which will not be repeated here.

[0169] It can be understood that the terminal device can calculate the uplink transmission power of the terminal device for SRS information transmission in BWP b, cell c, carrier f, subframe i according to the SRS parameters.

[0170] Optionally, in the first UL PC parameter set, the parameter value of each SRS is lower than the value of the same type of parameter in the second UL PC parameter set. O_SRS，b，f，c (q s ) is compared with P in the second UL PC parameter set O_SRS，b，f，c (q s ) has a lower value.

[0171] Optionally, in the first UL PC parameter set, the parameter value of each SRS is higher than the value of the same type of parameter in the second UL PC parameter set. O_SRS，b，f，c (q s ) compared to P in the second UL PC parameter set O_SRS，b，f，c (q s ) takes a higher value.

[0172] S403: The terminal device determines the UL PC parameter set to be used from the first UL PC parameter set and the second UL PC parameter set according to the working mode configuration information.

[0173] It can be understood that the UL PC parameter set to be used determined by the terminal device can be used to calculate the uplink transmit power of the uplink signal to be sent.

[0174] In an optional embodiment, after the terminal device determines to use the first UL PC parameter set, it calculates the first uplink transmit power of the uplink signal to be sent according to the first UL PC parameter set, and transmits the uplink signal to be sent to the network device at the first uplink transmit power.

[0175] In an optional embodiment, after the terminal device determines to use the second UL PC parameter set, it calculates the second uplink transmit power of the uplink signal to be sent according to the second UL PC parameter set, and transmits the uplink signal to be sent to the network device with the second uplink transmit power.

[0176] In the embodiment described above where the working mode configuration information includes the time-frequency resource configuration information of the working mode, the terminal device can determine the working mode corresponding to the time-frequency resource of the uplink signal to be transmitted based on the time-frequency resource configuration information, and adopt the UL PC parameter set corresponding to the working mode. It can be understood that the working mode is one of the non-full-duplex mode and the full-duplex mode, and the UL PC parameter set is one of the first UL PC parameter set and the second UL PC parameter set. In this embodiment, step S403 may include step S4031 and step S4033:

[0177] S4031: When the terminal device determines, based on the time-frequency resource configuration information, that the signal to be sent corresponds to a time-frequency region of a non-full-duplex mode, it determines to use the first UL PC parameter set.

[0178] It can be understood that the time-frequency resource configuration information includes the uplink and downlink information of each time domain resource and each frequency domain resource, for example, the frequency domain resources corresponding to the terminal device and other frequency domain resources, and the uplink and downlink information of each time slot.

[0179] Optionally, in the time slot where the signal to be sent is located, if the uplink and downlink information of the frequency domain resources corresponding to the terminal device and other frequency domain resources of the carrier are consistent, for example, both are UL, then it is determined that the signal to be sent corresponds to the time-frequency region of the non-full-duplex mode, and it is determined to use the first UL PC parameter set.

[0180] S4033: When the terminal device determines, based on the time-frequency resource configuration information, that the signal to be sent corresponds to the time-frequency region of the full-duplex mode, it determines to use the second UL PC parameter set.

[0181] Optionally, in the time slot where the signal to be sent is located, if the uplink and downlink information of the frequency domain resources corresponding to the terminal device and other frequency domain resources of the carrier include uplink and downlink, for example, one is UL and the other is DL, then it is determined that the signal to be sent corresponds to the time-frequency region of the full-duplex mode, and it is determined to use the second UL PC parameter set.

[0182] By executing steps S4031 and S4033, the terminal device can directly determine the operating mode corresponding to the signal to be transmitted based on the time-frequency resource configuration information. Optionally, the time-frequency resource configuration information can be configuration information for a period of time, covering multiple time slots. Therefore, the terminal device can determine the operating mode of the uplink signal to be transmitted in multiple time slots based on the time-frequency resource configuration information, thereby determining the UL PC parameter set used to calculate the uplink transmit power of the multiple time slots.

[0183] In the embodiment described above where the operating mode configuration information includes indication information of the operating mode, the terminal device can determine the operating mode corresponding to the signal to be transmitted based on the indication information of the operating mode, and adopt the UL PC parameter set corresponding to the operating mode. It can be understood that the operating mode is one of non-full-duplex mode and full-duplex mode, and the UL PC parameter set is one of the first UL PC parameter set and the second UL PC parameter set. In this embodiment, step S403 may include steps S4032 and S4034:

[0184] S4032: When the terminal device determines that it is working in a non-full-duplex mode according to the indication information of the working mode, it determines to use the first UL PC parameter set.

[0185] It can be understood that the operating mode indication information includes non-full-duplex mode indication information and full-duplex mode indication information, wherein the non-full-duplex mode indication information is used to indicate that the signal to be sent by the terminal device corresponds to the non-full-duplex mode.

[0186] Optionally, the terminal device may determine to use the first UL PC parameter set based on the indication information that the working mode is a non-full-duplex mode.

[0187] S4034: When the terminal device determines to operate in full-duplex mode according to the indication information of the operating mode, it determines to use the second UL PC parameter set.

[0188] It can be understood that the indication information of the working mode includes indication information of non-full-duplex mode and indication information of full-duplex mode. Among them, the indication information of full-duplex mode is used to indicate that the signal to be sent by the terminal device corresponds to the full-duplex mode.

[0189] Optionally, the terminal device may determine to use the second UL PC parameter set based on the indication information that the working mode is the full-duplex mode.

[0190] By executing steps S4032 and S4034, the terminal device can directly determine the operating mode corresponding to the signal to be transmitted based on the operating mode indication information. Optionally, the operating mode indication information can indicate the operating mode for a period of time, covering multiple time slots. Therefore, the terminal device can determine the operating mode of the uplink signal to be transmitted in multiple time slots based on the operating mode indication information, thereby determining the UL PC parameter set used to calculate the uplink transmit power of the multiple time slots.

[0191] Accordingly, an embodiment of the present application provides a communication method, which is applied to a network device in the communication system shown in Figure 1. Optionally, the network device may be a base station. As shown in Figure 5, the method may include S501-S502:

[0192] S501: The network device sends working mode configuration information to the terminal device.

[0193] In an optional implementation, the working mode configuration information includes time-frequency resource configuration information of the working mode. For the time-frequency resource configuration information of the working mode, reference may be made to the above description in conjunction with FIG4 , which will not be repeated here.

[0194] In an optional embodiment, the working mode configuration information includes indication information of the working mode. For the indication information of the working mode, reference can be made to the above description in conjunction with FIG4 , which will not be repeated here.

[0195] S502: The network device sends a first UL PC parameter set and a second UL PC parameter set to the terminal device.

[0196] The first UL PC parameter set corresponds to a non-full-duplex mode, and the second UL PC parameter set corresponds to a full-duplex mode.

[0197] It can be understood that for uplink signals corresponding to non-full-duplex mode, the terminal device calculates its uplink transmit power according to the first UL PC parameter set; and for uplink signals corresponding to full-duplex mode, the terminal device calculates its uplink transmit power according to the second UL PC parameter set.

[0198] Optionally, the network device may configure parameters in the first UL PC parameter set based on absolute values.

[0199] Optionally, the network device may configure the parameters in the second UL PC parameter set based on the offset value, for example, configuring the parameters in the second UL PC parameter set according to the relative value or offset value of the corresponding parameter in the first UL PC parameter set.

[0200] In an optional implementation, the network device may detect the transmission status of the communication system and configure the first UL PC parameter set and the second UL PC parameter set according to the detection result.

[0201] For example, if the detection result indicates that the CLI is large, the network device can configure the power value calculated by the parameters in the second UL PC parameter set to be larger than the power value calculated by the parameters in the first UL PC parameter set, thereby increasing the uplink transmission power in full-duplex mode to suppress the received CLI.

[0202] For another example, if the detection result indicates that the target terminal device causes greater interference to other terminal devices, the network device may configure the power value calculated by the parameters in the second UL PC parameter set to be smaller than the power value calculated by the parameters in the first UL PC parameter set, thereby reducing the uplink transmission power in full-duplex mode, thereby reducing the interference of the target terminal device to other terminal devices.

[0203] For other contents such as specific parameters of the first UL PC parameter set and the second UL PC parameter set, reference may be made to the above description in conjunction with FIG. 4 , which will not be repeated here.

[0204] As an example, the UL PC parameter set adopted by the terminal device can be dynamically indicated to the terminal device by configuration information or indication information, without the terminal device having to determine the time-frequency domain position or working mode. Accordingly, an embodiment of the present application provides a communication method applied to a terminal device in the communication system shown in Figure 1. Optionally, the terminal device is a UE. As shown in Figure 6, the method may include S601-S602:

[0206] The first UL PC parameter set corresponds to a non-full-duplex mode, and the second UL PC parameter set corresponds to a full-duplex mode.

[0207] It can be understood that for uplink signals corresponding to non-full-duplex mode, the terminal device calculates its uplink transmit power according to the first UL PC parameter set; and for uplink signals corresponding to full-duplex mode, the terminal device calculates its uplink transmit power according to the second UL PC parameter set.

[0208] For specific contents of the first UL PC parameter set and the second UL PC parameter set, reference may be made to the above description in conjunction with FIG. 4 , which will not be repeated here.

[0209] S602: The terminal device receives configuration information or indication information of the UL PC parameter set sent by the network device.

[0210] In an optional embodiment, the terminal device may receive configuration information of a UL PC parameter set sent by a network device. The configuration information of the UL PC parameter set is used to indicate the UL PC parameter set used by the terminal device, for example, indicating that the terminal device uses a first UL PC parameter set, or indicating that the terminal device uses a second UL PC parameter set.

[0211] The configuration information of the UL PC parameter set may include configuration information of the first UL PC parameter set or configuration information of the second UL PC parameter set.

[0212] Optionally, the configuration information of the UL PC parameter set is sent in one of a system information block (SIB), an RRC signaling, and a MAC-CE signaling.

[0213] In an optional embodiment, the terminal device may receive indication information of a UL PC parameter set sent by the network device. The indication information of the UL PC parameter set is used to indicate the UL PC parameter set adopted by the terminal device, for example, indicating that the terminal device adopts a first UL PC parameter set, or indicating that the terminal device adopts a second UL PC parameter set.

[0214] The indication information of the UL PC parameter set may include indication information of the first UL PC parameter set or indication information of the second UL PC parameter set.

[0215] Optionally, the UL PC parameter set indication information is sent in one of RRC signaling, MAC-CE signaling, DCI, and Random Access Response (Random Access Response, RAR).

[0216] Optionally, in an implementation manner in which the indication information is sent based on DCI, the field in the DCI where the indication information is located may adopt the following five schemes:

[0217] First, a specific state of the "SRS resource set indicator" field in the DCI indicates the first and second UL PC parameter sets.

[0218] For example, if the "SRS resource set indicator" field has a first value, it indicates a first UL PC parameter set; if the "SRS resource set indicator" field has a second value, it indicates a second UL PC parameter set.

[0219] Second, a specific state of the "SRS resource indicator" field in the DCI indicates the first and second UL PC parameter sets.

[0220] For example, if the "SRS resource indicator" field has a first value, it indicates a first UL PC parameter set; if the "SRS resource indicator" field has a second value, it indicates a second UL PC parameter set.

[0221] Third, a specific state of the "Open-loop power control parameter set indication" field in the DCI indicates the first and second UL PC parameter sets.

[0222] For example, if the "Open-loop power control parameter set indication" field has a first value, it indicates a first UL PC parameter set; if the "Open-loop power control parameter set indication" field has a second value, it indicates a second UL PC parameter set.

[0223] The fourth type is a new field in the DCI, which indicates the first and second UL parameter sets.

[0224] For example, a first field is added to the DCI, wherein if the first field has a first value, it indicates a first UL PC parameter set; if the first field has a second value, it indicates a second UL PC parameter set.

[0225] Fifth, in the fields corresponding to the above four solutions, two or more fields jointly indicate the first and second UL PC parameter sets.

[0226] For example, if the "SRS resource set indicator" field has the first value and the "SRS resource indicator" field has the second value, it indicates the first UL PC parameter set; if the "SRS resource set indicator" field has the third value and the "SRS resource indicator" field has the fourth value, it indicates the second UL PC parameter set.

[0227] For another example, a first field and a second field are added to the DCI. If the first field has the first value and the second field has the second value, it indicates the first UL PC parameter set; if the first field has the third value and the second field has the fourth value, it indicates the second UL PC parameter set.

[0238] Optionally, when the indication information is indication information of the second UL PC parameter set, it is determined to use the second UL PC parameter set.

[0239] Optionally, in an embodiment where the indication information is sent based on DCI, the following five methods may be used to obtain the indication information from a specific field in the DCI. The field where the indication information is located in the DCI may refer to the above description of step S602 and will not be repeated here.

[0240] Accordingly, an embodiment of the present application provides a communication method, which is applied to the communication system shown in Figure 1. Specifically, the method is applied to a network device. As shown in Figure 7, the method may include S701-S702:

[0241] S701: The network device sends a first UL PC parameter set and a second UL PC parameter set to the terminal device.

[0242] The first UL PC parameter set corresponds to a non-full-duplex mode, and the second UL PC parameter set corresponds to a full-duplex mode.

[0244] For specific contents of the first UL PC parameter set and the second UL PC parameter set, reference may be made to the above description in conjunction with FIG. 4 , which will not be repeated here.

[0245] S702: The network device sends configuration information or instruction information of the UL PC parameter set to the terminal device.

[0246] In an optional implementation, the network device may send configuration information of a UL PC parameter set to the terminal device. The configuration information of the UL PC parameter set is used to indicate the UL PC parameter set used by the terminal device, for example, indicating that the terminal device uses a first UL PC parameter set, or indicating that the terminal device uses a second UL PC parameter set.

[0247] The configuration information of the UL PC parameter set may include configuration information of the first UL PC parameter set or configuration information of the second UL PC parameter set.

[0248] Optionally, the configuration information of the UL PC parameter set is sent in one of system information blocks SIB, RRC signaling, and MAC CE signaling.

[0249] In an optional implementation, the network device may send an indication of a UL PC parameter set to the terminal device. The indication of the UL PC parameter set is used to indicate the UL PC parameter set used by the terminal device, for example, indicating that the terminal device uses a first UL PC parameter set, or indicating that the terminal device uses a second UL PC parameter set.

[0250] The indication information of the UL PC parameter set may include indication information of the first UL PC parameter set or indication information of the second UL PC parameter set.

[0251] Optionally, the sending method of the indication information of the UL PC parameter set includes one of RRC signaling, MAC-CE signaling, DCI, and RAR.

[0252] Optionally, in an implementation manner in which the indication information is sent based on DCI, the following five indication schemes are adopted in DCI:

[0253] First, a specific state of the "SRS resource set indicator" field in the DCI indicates the first and second UL PC parameter sets.

[0254] For example, if the "SRS resource set indicator" field has a first value, it indicates a first UL PC parameter set; if the "SRS resource set indicator" field has a second value, it indicates a second UL PC parameter set.

[0255] Second, a specific state of the "SRS resource indicator" field in the DCI indicates the first and second UL PC parameter sets.

[0256] For example, if the "SRS resource indicator" field has a first value, it indicates a first UL PC parameter set; if the "SRS resource indicator" field has a second value, it indicates a second UL PC parameter set.

[0257] Third, a specific state of the "Open-loop power control parameter set indication" field in the DCI indicates the first and second UL PC parameter sets.

[0258] For example, if the "Open-loop power control parameter set indication" field has a first value, it indicates a first UL PC parameter set; if the "Open-loop power control parameter set indication" field has a second value, it indicates a second UL PC parameter set.

[0259] The fourth type is a new field in the DCI, which indicates the first and second UL parameter sets.

[0260] For example, a first field is added to the DCI, wherein if the first field has a first value, it indicates a first UL PC parameter set; if the first field has a second value, it indicates a second UL PC parameter set.

[0261] Fifth, in the fields corresponding to the above four solutions, two or more fields jointly indicate the first and second UL PC parameter sets.

If the first field has the first value and the second field has the second value, it indicates the first UL PC parameter set; if the first field has the third value and the second field has the fourth value, it indicates the second UL PC parameter set.

[0264] It can be understood that the above are only two examples, and in other optional embodiments, other field combinations can also be adopted.

[0265] As an example, a terminal device can determine its operating state based on measurement results of a specific subband and calculate the uplink transmit power based on the UL PC parameter set corresponding to the operating state. Accordingly, an embodiment of the present application provides a communication method applied to a terminal device in the communication system shown in Figure 1. Optionally, the terminal device can be a UE. As shown in Figure 8, the method may include S801-S802:

[0266] S801: The terminal device receives a first UL PC parameter set and a second UL PC parameter set sent by a network device.

[0267] The first UL PC parameter set corresponds to a non-full-duplex mode, and the second UL PC parameter set corresponds to a full-duplex mode.

[0268] It can be understood that for uplink signals corresponding to non-full-duplex mode, the terminal device calculates its uplink transmit power according to the first UL PC parameter set; and for uplink signals corresponding to full-duplex mode, the terminal device calculates its uplink transmit power according to the second UL PC parameter set.

[0269] For specific contents of the first UL PC parameter set and the second UL PC parameter set, reference may be made to the above description in conjunction with FIG. 4 , which will not be repeated here.

[0270] S802: The terminal device determines a UL PC parameter set to be used from the first UL PC parameter set and the second UL PC parameter set according to a measurement result of the target subband.

[0271] It can be understood that the UL PC parameter set to be used determined by the terminal device can be used to calculate the uplink transmit power of the uplink signal to be sent.

[0272] In an optional embodiment, after the terminal device determines to use the first UL PC parameter set, it calculates the first uplink transmit power of the uplink signal to be sent according to the first UL PC parameter set, and transmits the uplink signal to be sent to the network device at the first uplink transmit power.

[0273] In an optional embodiment, after the terminal device determines to use the second UL PC parameter set, it calculates the second uplink transmit power of the uplink signal to be sent according to the second UL PC parameter set, and transmits the uplink signal to be sent to the network device with the second uplink transmit power.

[0274] Optionally, the measurement amount may include at least one of SS-RSRP, CSI-RSRP, SRS-RSRP, RSSI, and CLI-RSSI.

[0275] Three specific implementation methods for determining the UL PC parameter set to be used based on the measurement results of the target subband are described below.

[0276] The first one is that the target subband is a subband adjacent to the uplink signal to be sent.

[0277] In this embodiment, the adjacent subbands of the uplink signal to be transmitted are measured, and the UL PC parameter set to be used is determined according to the measurement result.

[0278] Optionally, if the measurement result is less than or equal to threshold 1, it is determined to use the first UL PC parameter set. It can be understood that a smaller measurement result indicates that there is no downlink signal in the adjacent subband, and thus the determination corresponds to non-full-duplex mode.

[0279] Optionally, if the measurement result is greater than a threshold value 1, it is determined to use the second UL PC parameter set. It can be understood that a larger measurement result indicates that there is a downlink signal in the adjacent subband, and therefore it is determined to correspond to the full-duplex mode.

[0280] Optionally, the threshold 1 is pre-agreed upon by a protocol, or pre-configured by a network device. As an example, before step S802 , the method further includes: receiving the threshold 1 sent by the network device.

[0281] The second type is that the target subband is the subband of the uplink signal to be sent.

[0282] In this embodiment, the subband of the uplink signal to be transmitted is measured, and the UL PC parameter set to be used is determined according to the measurement result.

[0283] Optionally, if the measurement result is less than or equal to threshold 2, it is determined to use the first UL PC parameter set. It can be understood that a smaller measurement result indicates that the target subband is not interfered with by adjacent subbands, and thus it is determined to correspond to non-full-duplex mode.

[0284] Optionally, if the measurement result is greater than threshold 2, it is determined to use the second UL PC parameter set. It can be understood that a larger measurement result indicates that the target subband is interfered with by an adjacent subband, and therefore it is determined to correspond to full-duplex mode.

[0285] Optionally, the threshold 2 is pre-agreed upon by a protocol, or pre-configured by the network device. As an example, before step S802, the method further includes: receiving the threshold 2 sent by the network device.

[0286] The third method involves the target subband being a designated subband. The designated subband is configured by the network device. In this embodiment, before step S802, the method further includes receiving configuration information and / or indication information for the measurement subband from the network device. Optionally, the configuration information and / or indication information for the measurement subband includes the designated subband number or frequency domain resource information for the subband.

[0287] Optionally, if the measurement result is less than or equal to the threshold 3, it is determined to use the first UL PC parameter set. It can be understood that a smaller measurement result indicates no interference from the designated subband, and thus it is determined to correspond to non-full-duplex mode.

[0288] Optionally, if the measurement result is greater than a threshold value 3, it is determined to use the second UL PC parameter set. It can be understood that a larger measurement result indicates interference from a designated subband, and therefore it is determined to correspond to the full-duplex mode.

[0289] Optionally, the threshold 3 is pre-agreed upon by a protocol, or pre-configured by the network device. As an example, before step S802, the method further includes: receiving the threshold 3 sent by the network device.

[0290] Accordingly, an embodiment of the present application provides a communication method, which is applied to a network device in the communication system shown in FIG1 . Optionally, the network device may be a base station. As shown in FIG9 , the method may include S901-S903:

[0291] S901: The network device sends a first UL PC parameter set and a second UL PC parameter set to the terminal device.

[0292] The first UL PC parameter set corresponds to a non-full-duplex mode, and the second UL PC parameter set corresponds to a full-duplex mode.

[0293] It can be understood that for uplink signals corresponding to non-full-duplex mode, the terminal device calculates its uplink transmit power according to the first UL PC parameter set; and for uplink signals corresponding to full-duplex mode, the terminal device calculates its uplink transmit power according to the second UL PC parameter set.

[0294] For specific contents of the first UL PC parameter set and the second UL PC parameter set, reference may be made to the above description in conjunction with FIG. 4 , which will not be repeated here.

[0295] S902: The network device sends configuration information of the measurement subband to the terminal device.

[0296] It can be understood that step S902 is an optional step.

[0297] Specifically, in the embodiment described above where the target subband is the execution subband, the network device needs to send configuration information of the measurement subband to the terminal device. The configuration information of the measurement subband is used to instruct the terminal device to determine the designated subband to be measured.

[0298] It can be understood that in the above-described implementation where the target subband is a subband adjacent to the uplink signal to be transmitted, and in the implementation where the target subband is a subband of the uplink signal to be transmitted, step S902 does not need to be performed.

[0299] Optionally, the configuration information of the measurement subband includes the number of the specified subband, or frequency domain resource and / or time domain resource information of the subband.

[0300] S903: The network device configures a threshold for measuring a sub-band for the terminal device.

[0301] It can be understood that step S903 is an optional step.

[0302] Specifically, in an embodiment where the threshold value of the sub-band measured by the network device is configured by the network device, the network device needs to send configuration information of the sub-band measured to the terminal device, including the threshold value of the sub-band measured.

[0303] It can be understood that in the embodiment described above where the threshold is specified by the protocol, step S903 does not need to be performed.

[0304] It can be understood that the threshold of the measurement subband is used to assist the terminal device in determining the UL PC parameter set to be adopted according to the measurement result of the measurement subband. Specifically, the terminal device compares the measurement result with the threshold to determine the UL PC parameter set to be adopted.

[0305] Optionally, in the embodiment described above where the target subband is a subband adjacent to the uplink signal to be transmitted, the network device configures the terminal device with threshold 1.
