Description

[Technical field]

[0001] The present application relates to the field of communications, and more particularly, to a communication method and device. [Background technology]

[0002] This application claims priority to Chinese Patent Application No. 202210237422.5, entitled "COMMUNICATION METHOD AND APPARATUS," filed with the China State Intellectual Property Office on March 11, 2022, which is incorporated herein by reference in its entirety.

[0003] In 5G new radio (NR), beamforming (BF) technology is usually used to obtain good directional gain, increase directional power, improve signal to interference plus noise ratio (SINR), and further improve the overall performance of the system, in order to avoid the attenuation generated in the process of signal propagation in space. Considering the balance between cost and performance, hybrid beamforming (HBF) technology, including digital beamforming and analog beamforming, is currently used. The antenna panel is the core component, i.e., the beam is received or transmitted through the antenna panel.

[0004] Currently, the discussion on antenna panels is based on the uplink transmission process regarding fast selection and switching of multi-antenna panels, and specifically discusses the definition of antenna panels and how to reflect antenna panels in the protocol, but does not relate to the issue of antenna panels on a terminal device transmitting transport blocks simultaneously. Summary of the Invention

[0005] The present application provides a communication method and a communication apparatus for effectively solving the problem of indicating the transmission mode of a terminal device in a multi-antenna panel scenario.

[0006] According to a first aspect, a communication method is provided. The communication method can be implemented by a terminal device, or can be implemented by a chip or circuit disposed in the terminal device. This is not limited in the present application.

[0007] The communication method includes receiving first information, where the first information indicates one mode or two modes, the one mode being one of a first mode, a second mode, or a third mode, and the two modes being two of the first mode, the second mode, or the third mode, where the first mode is transmitting a transport block via one antenna panel, the second mode is transmitting the same transport block at at least two instants via the at least one antenna panel, the transport block being transmitted at each of the at least two instants via the one antenna panel, and the third mode is simultaneously transmitting the same transport block via the at least two antenna panels, different antenna panels transmitting different portions of the transport block, or the third mode is simultaneously transmitting one transport block via each of the at least two antenna panels; and transmitting the transport block in the one mode or one of the two modes indicated by the first information.

[0008] Therefore, in the present application, in a multi-antenna panel scenario, the terminal device receives the first information to implement indicating a transmission mode of at least one antenna panel on the terminal device. That is, the first information can indicate one or two modes of a first mode, a second mode, or a third mode. The present application also applies to a multi-transmission point scenario. When the terminal device transmits a transport block to one or more transmission / reception points via a multi-antenna panel, the first information indicates the transmission mode of the antenna panel on the terminal device.

[0009] Referring to the first aspect, in some implementations of the first aspect, when the value of the first information is a first value, the first information indicates two modes, the two modes being the first mode and the second mode, or when the value of the first information is a second value, the first information indicates one mode, the mode being the third mode, or when the value of the first information is a first value, the first information indicates two modes, the two modes being the first mode and the second mode, or when the value of the first information is a second value, the first information indicates two modes, the two modes being the first mode and the third mode, or when the value of the first information is a first value, the first information indicates two modes, the two modes being the first mode and the third mode, or when the value of the first information is a second value, the first information indicates one mode, the mode being the second mode.

[0010] Thus, in the present application, a terminal device can receive first information whose values ​​are first and second values ​​for indicating the first and second modes, and the third mode, respectively, or a terminal device can receive first information whose values ​​are first and second values ​​for indicating the first and second modes, and the first and third modes, respectively, or a terminal device can receive first information whose values ​​are first and second values ​​for indicating the first and third modes, and the second mode, respectively.

[0011] Referring to the first aspect, in some implementations of the first aspect, when the first information indicates two modes, the method further includes a step of receiving, by the terminal device, second information, where the second information indicates one of the two modes, and the step of transmitting the transport block in the one mode or one of the two modes indicated by the first information includes a step of transmitting the transport block based on the first information and the second information.

[0012] Therefore, in the present application, when the first information indicates two modes among the first mode, the second mode, and the third mode, the terminal device can determine a specific mode from the two modes based on the second information, which accurately indicates the transmission mode of the multi-antenna panel on the terminal device. In addition, when the second information is at least one bit in the downlink control information DCI, dynamic switching between the first mode and the second mode or between the first mode and the third mode can be implemented, thereby reducing network delay.

[0013] Referring to the first aspect, in some implementations of the first aspect, the second information is at least one bit in a radio resource control RRC, a medium access control control element MAC CE, or downlink control information DCI.

[0014] Therefore, in the present application, when the second information is two bits in the RRC, MAC CE, or DCI, the transmission mode of the multi-antenna panel at the terminal device side can be indicated without increasing the bit overhead.

[0015] Referring to the first aspect, in some implementations of the first aspect, the first information is one bit in an RRC, a MAC CE, or a DCI.

[0016] Therefore, in this application, one bit in the RRC, MAC CE, or DCI is introduced to indicate one mode or two modes in multiple transmission modes. When one bit in the RRC, MAC CE, or DCI indicates two transmission modes, two bits configured in the DCI can indicate one of the two modes. This reduces the impact of standardization.

[0017] Referring to the first aspect, in some implementations of the first aspect, the first mode, the second mode, or the third mode includes at least two submodes, and parameter sets of any two submodes in the same mode are different, and the parameter sets include at least one of a channel set, a channel group set, a time domain resource set, a frequency domain resource set, or a spatial domain resource set, and when the first information indicates a mode, the first information further indicates a submode within the mode.

[0018] Therefore, in the present application, when the first information indicates one mode, the first information further indicates a sub-mode within the mode, such that the terminal device receives the first information to implement accurately indicating the sub-mode corresponding to the mode.

[0019] Referring to the first aspect, in some implementations of the first aspect, the first information is at least two bits in an RRC, a MAC CE, or a DCI.

[0020] Therefore, in the present application, when the first information is two bits configured in the DCI, the value of the two bits configured in the DCI may indicate one of a plurality of transmission modes, and the value of the two bits configured in the DCI further indicates a sub-mode corresponding to the mode, which solves the problem of indicating a sub-mode corresponding to a transmission mode of an antenna panel at a terminal device side without increasing bit overhead.

[0021] Referring to the first aspect, in some implementations of the first aspect, the first information indicates one mode, and when a value of the first information belongs to a first value set, the first information indicates that the mode is a first mode, and the first value set includes at least one value, or when a value of the first information belongs to a second value set, the first information indicates that the mode is a second mode, and the second value set includes at least one value, or when a value of the first information belongs to a third value set, the first information indicates that the mode is a third mode, and the third value set includes at least one value.

[0022] Referring to the first aspect, in some implementations of the first aspect, the first information indicates one or two modes from a plurality of modes, where the plurality of modes includes one or more of the first mode, the second mode, or the third mode, and the method further includes a step of receiving third information, where the third information indicates that the plurality of modes includes the third mode.

[0023] Referring to the first aspect, in some implementations of the first aspect, the third information may be an RRC, a MAC CE, or a DCI.

[0024] Referring to the first aspect, in some implementations of the first aspect, the third information includes a first field, and when the value of the first field is a third value, the third information indicates that the multiple modes include the third mode, or when the value of the first field is a fourth value, the third information indicates that the multiple modes do not include the third mode. For example, the third value may be 0 and the fourth value is 1, or the third value is 1 and the fourth value is 0.

[0025] Referring to the first aspect, in some implementations of the first aspect, whether the plurality of modes includes the third mode may be determined based on whether the third information includes the first field. When the third information includes the first field, the plurality of modes includes the third mode, or when the third information does not include the first field, the plurality of modes does not include the third mode. Alternatively, when the third information includes the first field, the plurality of modes does not include the third mode, or when the third information does not include the first field, the plurality of modes includes the third mode.

[0026] According to a second aspect, a communication method is provided. The communication method can be implemented by a network device, or can be implemented by a chip or circuit disposed in the network device. This is not limited in the present application.

[0027] The method includes the steps of determining first information, where the first information indicates one mode or two modes, the one mode being one of a first mode, a second mode, or a third mode, and the two modes being two of the first mode, the second mode, or the third mode, where the first mode is transmitting a transport block via one antenna panel, the second mode is transmitting the same transport block at at least two instants via the at least one antenna panel, the transport block being transmitted at each of the at least two instants via the one antenna panel, and the third mode is simultaneously transmitting the same transport block via the at least two antenna panels, different antenna panels transmitting different portions of the transport block, or the third mode is simultaneously transmitting one transport block via each of the at least two antenna panels; and transmitting the first information.

[0028] Therefore, in the present application, in a multi-antenna panel scenario, the network device can transmit the first information to the terminal device to implement indicating the transmission mode of the multi-antenna panel on the terminal device. That is, the first information can indicate one or two modes of the first mode, the second mode, or the third mode. The present application also applies to a multi-transmission point scenario. When the terminal device transmits a transport block to one or more transmission / reception points via the multi-antenna panel, the first information transmitted by the network device is received, and the first information indicates the transmission mode of the antenna panel on the terminal device.

[0029] Referring to the second aspect, in some implementations of the second aspect, when the value of the first information is a first value, the first information indicates two modes, the two modes being the second mode and the third mode, or when the value of the first information is a second value, the first information indicates one mode, the mode being the first mode, or when the value of the first information is a first value, the first information indicates two modes, the two modes being the second mode and the third mode, or when the value of the first information is a second value, the first information indicates two modes, the two modes being the first mode and the third mode, or when the value of the first information is a first value, the first information indicates two modes, the two modes being the first mode and the third mode, or when the value of the first information is a second value, the first information indicates one mode, the mode being the second mode.

[0030] Thus, in the present application, the network device can transmit first information, the values ​​of which are first and second values ​​for indicating a first mode, a second mode, and a third mode, respectively, of an antenna panel of a terminal device, or for indicating a first mode, a second mode, and a first mode, and a third mode, respectively, of an antenna panel on a terminal device, or for indicating a second mode, a first mode, and a third mode, respectively, of an antenna panel on a terminal device.

[0031] Referring to the second aspect, in some implementations of the second aspect, when the first information indicates two modes, the method further includes a step of transmitting second information, where the second information indicates one of the two modes.

[0032] Therefore, in the present application, when the first information indicates two modes among the first mode, the second mode, and the third mode, the network device can transmit the second information so that the terminal device determines a specific mode from the two modes. This implements accurately indicating the transmission mode of the antenna panel on the terminal device. In addition, when the second information is at least one bit in the downlink control information DCI, dynamic switching between the first mode and the second mode or between the first mode and the third mode can be implemented, thereby reducing network delay.

[0033] Referring to the second aspect, in some implementations of the second aspect, the second information is at least one bit in a radio resource control RRC, a medium access control control element MAC CE, or downlink control information DCI.

[0034] Therefore, in the present application, when the second information is two bits in the RRC, MAC CE, or DCI, the transmission mode of the multi-antenna panel at the terminal device side can be indicated without increasing the bit overhead.

[0035] Referring to the second aspect, in some implementations of the second aspect, the first information is one bit in an RRC, a MAC CE, or a DCI.

[0036] Therefore, in this application, one bit in the RRC, MAC CE, or DCI is introduced to indicate one mode or two modes in multiple transmission modes. When one bit in the RRC, MAC CE, or DCI indicates two transmission modes, two bits configured in the DCI can indicate one of the two modes. This reduces the impact of standardization.

[0037] Referring to the second aspect, in some implementations of the second aspect, the first mode, the second mode, or the third mode includes at least two submodes, and parameter sets of any two submodes in the same mode are different, and the parameter sets include at least one of a channel set, a channel group set, a time domain resource set, a frequency domain resource set, or a spatial domain resource set, and when the first information indicates a mode, the first information further indicates a submode within the mode.

[0038] Therefore, in the present application, when the first information indicates one mode, the first information further indicates a sub-mode within the mode, such that the network device can transmit the first information to implement accurately indicating the sub-mode corresponding to the mode.

[0039] Referring to the second aspect, in some implementations of the second aspect, the first information is at least two bits in an RRC, a MAC CE, or a DCI.

[0040] Therefore, in the present application, when the first information is two bits configured in the DCI, the value of the two bits configured in the DCI may indicate one of a plurality of transmission modes, and the value of the two bits configured in the DCI further indicates a sub-mode corresponding to the mode, which solves the problem of indicating a sub-mode corresponding to a transmission mode of a multi-antenna panel at the terminal device side without increasing bit overhead.

[0041] Referring to the second aspect, in some implementations of the second aspect, the first information indicates one mode, and when the value of the first information belongs to a first value set, the first information indicates that the mode is a first mode, and the first value set includes at least one value, or when the value of the first information belongs to a second value set, the first information indicates that the mode is a second mode, and the second value set includes at least one value, or when the value of the first information belongs to a third value set, the first information indicates that the mode is a third mode, and the third value set includes at least one value.

[0042] Referring to the second aspect, in some implementations of the second aspect, the first information indicates one or two modes from a plurality of modes, where the plurality of modes includes one or more of the first mode, the second mode, or a third mode, and the method may further include a step of transmitting third information, where the third information indicates whether the plurality of modes includes the third mode.

[0043] Referring to the second aspect, in some implementations of the second aspect, the third information may be an RRC, a MAC CE, or a DCI.

[0044] Referring to the second aspect, in some implementations of the second aspect, the third information includes a first field, and when the value of the first field is a third value, the third information indicates that the multiple modes include the third mode, or when the value of the first field is a fourth value, the third information indicates that the multiple modes do not include the third mode. For example, the third value may be 0 and the fourth value is 1, or the third value is 1 and the fourth value is 0.

[0045] Referring to the second aspect, in some implementations of the second aspect, whether the plurality of modes includes the third mode may be indicated based on whether the third information includes the first field. When the third information includes the first field, the plurality of modes includes the third mode, or when the third information does not include the first field, the plurality of modes does not include the third mode. Alternatively, when the third information includes the first field, the plurality of modes does not include the third mode, or when the third information does not include the first field, the plurality of modes includes the third mode.

[0046] According to a third aspect, a communication method is provided. The communication method can be implemented by a terminal device, or can be implemented by a chip or circuit disposed in the terminal device. This is not limited in the present application.

[0047] The communication method includes the steps of receiving first information, where the first information is used to determine a target mode from at least two modes, the at least two modes including at least two of a first mode, a second mode, and a third mode, where the first mode is transmitting a transport block via one antenna panel, the second mode is transmitting the same transport block at at least two instants via the at least one antenna panel, the transport block being transmitted at each of the at least two instants via the one antenna panel, and the third mode is simultaneously transmitting the same transport block via at least two antenna panels, different antenna panels transmitting different portions of the transport block, or the third mode is simultaneously transmitting one transport block via each of the at least two antenna panels; and transmitting the transport block in the target mode.

[0048] Therefore, in the present application, in a multi-antenna panel scenario, the terminal device can receive the first information and determine a target transmission mode. The present application also applies to a multi-transmission point scenario. When the terminal device transmits a transport block to one or more transmission / reception points through an antenna port, the terminal device receives the first information and determines a target mode.

[0049] Referring to the third aspect, in some implementations of the third aspect, when the at least two modes are two modes, the two modes are a first mode and a second mode, or the two modes are a first mode and a third mode, or the two modes are a second mode and a third mode, and the first information indicates one of the two modes, where the mode is the target mode. Referring to the third aspect, in some implementations of the third aspect, when the at least two modes are three modes, the first information indicates one mode or two modes of the three modes, and when the first information indicates two modes, the method further includes a step of receiving second information, where the second information indicates one of the two modes, where the mode is the target mode.

[0050] Therefore, in the present application, when the at least two modes are three modes, the terminal device receives the second information and determines the target mode.

[0076] According to a fifth aspect, a communication method is provided. The communication method can be implemented by a terminal device, or can be implemented by a chip or circuit disposed in the terminal device. This is not limited in the present application.

[0078] Therefore, in the present application, in a multi-antenna panel scenario, the terminal device receives the first information to implement indicating a transmission mode of at least one antenna panel on the terminal device. That is, the first information can indicate one or more of a first mode, a second mode, or a third mode. The present application also applies to a multi-transmission point scenario. When the terminal device transmits a transport block to one or more transmission / reception points via the multi-antenna panel, the first information indicates the transmission mode of the antenna panel on the terminal device.

[0080] Therefore, in the present application, when M is 2, in a multi-antenna panel scenario, the terminal device can receive the first information to implement indicating the transmission mode of the antenna panel on the terminal device. The present application also applies to a multi-transmission point scenario. When the terminal device transmits a transport block to one or more transmission / reception points via the antenna panel, the first information is received, and the first information indicates the transmission mode of the antenna panel on the terminal device.

[0081] Referring to the fifth aspect, in some implementations of the fifth aspect, when M is 2, the first information is at least one bit in a radio resource control RRC, a medium access control control element MAC CE, or downlink control information DCI.

[0082] Referring to the fifth aspect, in some implementations of the fifth aspect, when M is 3, the value of N may be 1 or 2. When N is 1, the first information indicates one mode from three modes, the three modes including the first mode, the second mode, and the third mode. In this case, the first information may be 1 bit or 2 bits. Alternatively, when N is 2, the first information indicates two modes from three modes, and the terminal device may transmit the transport block in one of the two modes, or when N is 2, the first information indicates two modes from the three modes.

[0150] The technical solutions in the embodiments of the present application are applicable to various communication systems, such as long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, universal mobile telecommunications system (UMTS), worldwide interoperability for microwave access (WiMAX) communication systems, fifth generation (5G) mobile communication systems, or NR. The technical solutions provided in the present application are further applicable to future communication systems, such as sixth generation mobile communication systems. Alternatively, the communication system may be a public land mobile network (PLMN), a device-to-device (D2D) communication system, a machine-to-machine (M2M) communication system, an internet of things (IoT) communication system, or another communication system.

[0151] Compared with 4G LTE (Long Term Evolution, NR) using low frequency bands, 5G NR (New Radio, NR) adds high frequency bands (generally considered higher than 6G), for example, 26 GHz, 28 GHz, 39 GHz, or 60 GHz frequency bands, to meet the requirements of three scenarios, including extended mobile bandwidth, massive connections, and high reliability and low latency in 5G NR. High frequency bands can achieve larger bandwidth and higher transmission speeds. Due to the high signal frequency, in the process of the signal propagating in space, serious attenuation occurs, which severely limits the signal coverage. To address this challenge, beamforming (BF) is used in 5G NR to obtain good directional gain, increase the directional power of different transmission directions, improve the signal to interference plus noise radio (SINR), and further improve the system performance. Considering the balance between deployment cost and system performance, hybrid beamforming (HBF) technology, including digital beamforming and analog beamforming, is used in the 5G NR research process. In the implementation process of beamforming technology, antenna panels are the core components, and beams are received or transmitted through the antenna panels. In the 5G NR deployment implementation process, directional beam technology is used. In order to implement wide-area coverage, base stations (BS) and terminals with multi-antenna panels are deployed. Especially for terminals, in order to implement wide-area coverage in the case of limited space and cost saving, the deployment of antenna panels has a more significant impact on the signal transmission performance of the terminal. In current commercial products, two or three antenna panels are generally built into mobile terminals, and more antenna panels, for example, four or eight antenna panels, may be built into fixed stations, for example, customer premises equipment (CPE) / fixed wireless access (FWA).

[0152] It should be understood that the antenna panel in the embodiments of the present application may be an antenna set. In addition, the antenna panel in the embodiments of the present application may be replaced with an "antenna set".

[0153] Optionally, the antenna set may be an antenna set whose transmit power can be controlled independently or separately. The antenna set may alternatively be an antenna set capable of independent or separate time adjustment. The antenna set may alternatively be an antenna set whose modulation and coding are performed independently or separately.

[0154] In implementation, the antenna panel in the embodiment of the present application may be one capability value in the capability value set list of the terminal device. Therefore, the antenna panel in the embodiment of the present application may be replaced with a "capability set" as an alternative. The capability value set may include the quality of a channel sounding reference signal (SRS) port, the maximum amount of SRS ports, the amount of layers transmitted in the uplink (UL), the maximum amount of layers transmitted in the UL, the coherence type of the antenna port, etc.

[0155] Optionally, there is a correspondence between the capability value set and a synchronization signal and physical broadcast channel block (SSB resource indicator, SSBRI), or there is a correspondence between the capability value set and a channel-state information reference signal (CSI-RS) resource indicator (CRI-RS resource indicator, CRI). Thus, one antenna panel may refer to one SSBRI or CRI.

[0156] In implementation, the antenna panel in the embodiments of the present application may be replaced with "SSBRI" or "CRI".

[0157] Optionally, the correspondence between the capability value set and the SSBRI or the correspondence between the capability value set and the CRI may be determined by the terminal device. The terminal device may report the correspondence between the capability value set and the SSBRI or the correspondence between the capability value set and the CRI to the network device in a beam report. Alternatively, the terminal device may report the capability value set, the SSBRI, or the CRI to the network device.

[0158] In implementation, the antenna panel in the embodiment of the present application may be an SRS set, and therefore the antenna panel in the present application may also be referred to as an "SRS set."

[0159] Optionally, in an embodiment of the present application, the definition of one antenna panel may be dynamically changed. For example, one antenna panel may include a capability set of four SRS ports at moment 1, and the antenna panel may include a capability set of two SRS ports at moment 2 after moment 1.

[0160] In the embodiment of the present application, a transport block (TB) is a basic unit for processing in the physical layer and for data exchange between the Media Access Control (MAC) sublayer and the physical layer. In the implementation, a transport block is a data block that contains a MAC protocol data unit (PDU).

[0161] A mode in an embodiment of the present application may be a transmission mode, a transmission rule, a mapping method, a mapping rule, or a resource determination method.

[0163] 1 is a diagram of an architecture of a wireless communication system according to an embodiment of the present application. As shown in FIG. 1, the wireless communication system 100 may include a network device 101 and a terminal device 102. The terminal device 102 may be connected to the network device 101. The network device 101 may also be referred to as a base station device.

[0164] It should be understood that the communication system 100 may include multiple terminal devices 102 and multiple network devices 101. This is not limited to this embodiment of the present application.

[0165] In implementation, the present application applies to multiple mobile communication scenarios, including, but not limited to, point-to-point transmission between a network device 101 and a terminal device 102 or between terminal devices 102, multi-hop transmission between a network device 101 and a terminal device 102, and DC (dual connectivity) or multi-connection between multiple base stations and user devices.

[0166] It should be understood that the terminal device 102 in the embodiment of the present application may be an unmanned aerial vehicle (UAV), an access terminal, a subscriber unit, a subscriber station, a mobile station, a relay station, a remote station, a remote terminal, a mobile device, a user terminal, a user equipment (UE), a terminal, a wireless communication device, a user agent, or a user equipment. The terminal device may alternatively be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication capabilities, a computing device, another processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a 5G network, a terminal device in a future evolved public land mobile network (PLMN), a terminal device in a future Internet of Vehicles, etc. This is not limited in the present embodiment of the present application.

[0167] By way of example and not of limitation, in the embodiment of the present application, the wearable device may also be referred to as an intelligent wearable device, which is a collective term for wearable devices developed by intelligently designing everyday wear through wearable technology, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that can be worn directly on the body and integrated into a user's clothing or accessories. A wearable device implements not only hardware devices, but also powerful functions, data exchange, and cloud interaction through software support. In a broad sense, intelligent wearable devices include full-featured large devices that can implement full or partial functions without relying on a smartphone, such as smart watches or smart glasses, and devices that are dedicated to one type of application and need to be used with other devices such as smartphones, such as various smart bands or smart jewelry for monitoring physical signs.

[0168] In addition, in the embodiment of the present application, the terminal device may alternatively be a terminal device in an internet of things (IoT) system. IoT is an important part of the future development of information technology. The main technical feature of IoT is to connect things to a network by using communication technology to implement an intelligent network for human-machine interconnection and thing-thing interconnection. In the embodiment of the present application, the IoT technology may implement mass connection, deep coverage, and terminal power connection, for example, by using narrowband (NB) technology.

[0169] In addition, in the embodiment of the present application, the terminal device may alternatively include a sensor, such as an intelligent printer, a train detector, or a gas station, etc. The main functions of the terminal device include: collecting data (by some terminal devices), receiving control information and downlink data of the network device, transmitting electromagnetic waves, and transmitting uplink data to the network device.

[0170] In the implementation, the terminal device 102 may alternatively be a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in autonomous driving, a wireless terminal in telemedicine, a wireless terminal in smart grid, a wireless terminal in smart city, a wireless terminal in smart home, etc. In the embodiment of the present application, the apparatus configured to implement the function of the terminal may be a terminal, or an apparatus, such as a chip system, that can support the terminal in implementing the function. The apparatus may be installed in the terminal. The chip system may include a chip, or may include a chip and another separate component.

[0171] The network device 101 of the embodiment of the present application includes an access network device, for example, a base station, where the BS may be a device deployed in a radio access network and capable of implementing wireless communication with a terminal. The base station may be in multiple forms, such as a macro base station, a micro base station, a relay station, and an access point. For example, the base station of the embodiment of the present application may be a base station in 5G. The base station in 5G may also be called a transmission / reception point or a 5G base station (next-generation Node B, gNB).

[0172] The network device 101 of the embodiment of the present application may be any communication device having a wireless transceiver function and configured to communicate with the terminal device 102. The device includes, but is not limited to, an evolved NodeB (eNB), a radio network controller (RNC), a NodeB (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (home evolved NodeB, HeNB or home NodeB, HNB), a baseBand unit (BBU), an access point (AP) in a wireless fidelity (Wi-Fi) system, a wireless relay node, a wireless backhaul node, a transmission point (TP), a transmission and reception point (TRP), etc. Alternatively, the device may be a gNB or a transmission point in a 5G system such as an NR system, may be an antenna panel or a group of antenna panels (including a multi-antenna panel) in a 5G system, or may be a network node such as a baseband unit or a distributed unit (DU) that includes a gNB or a transmission point.

[0173] In some deployments, the network device 101 of the embodiment of the present application may be a central unit (CU) or a DU, or the network device includes a CU and a DU. The gNB may further include an active antenna unit (AAU). The CU implements some functions of the gNB, and the DU implements some functions of the gNB. For example, the CU is responsible for processing non-real-time protocols and services, and implements functions of the radio resource control (RRC) layer and the packet data convergence protocol (PDCP) layer. The DU is responsible for processing physical layer protocols and real-time services, and implements functions of the radio link control (RLC) layer, the media access control (MAC) layer, and the physical (PHY) layer. The AAU implements some physical layer processing functions, radio frequency processing, and functions related to active antennas. Information at the RRC layer eventually becomes information at the PHY layer or is converted from information at the PHY layer. Therefore, in this architecture, higher layer signaling, such as RRC layer signaling, may also be considered as being transmitted by the DU, or transmitted by the DU and AAU. It may be understood that the network device may be a device including one or more of a CU node, a DU node, and an AAU node. In addition, the CU may be classified as a network device in an access network (radio access network, RAN), or the CU may be classified as a network device in a core network (CN). This is not limited in the present application.

[0174] Furthermore, the CU may be divided into a control plane central unit (CU-CP) and a user plane control unit (CU-UP). The CU-CP and the CU-UP may be deployed on different physical devices. The CU-CP is responsible for the control plane function and mainly includes an RRC layer and a PDCP-C layer. The PDCP-C layer is mainly responsible for data encryption and decryption, integrity protection, data transmission, etc. on the control plane. The CU-UP is responsible for the user plane function and mainly includes an SDAP layer and a PDCP-U layer. The SDAP layer is mainly responsible for processing data of the core network and mapping flows to bearers. The PDCP-U layer is mainly responsible for at least one function of encryption and decryption, integrity protection, header compression, serial number maintenance, data transmission, etc. on the data plane. Specifically, the CU-CP and the CU-UP are connected through a communication interface (e.g., an E1 interface). The CU-CP represents a network device and is connected to a core network device through a communication interface (e.g., an Ng interface) and is connected to a DU through a communication interface (e.g., an F1-C (control plane) interface). The CU-UP is connected to a DU through a communication interface (e.g., an F1-U (user plane) interface). In another possible implementation, the PDCP-C layer is also included in the CU-UP.

[0175] It can be understood that the above protocol layer division between CU and DU, and protocol layer division between CU-CP and CU-UP are merely examples, and there may be other division methods, which are not limited in the embodiments of the present application.

[0176] The network device 101 of the present application may be a device including a CU or a DU, or a CU and a DU, or a device including a control plane CU node (CU-CP node), a user plane CU node (CU-UP node), and a DU node.

[0177] In the embodiment of the present application, the network device 101 and the terminal device 102 can be deployed on land, on water, or in the air on an aircraft, balloon, or satellite, including an indoor device, an outdoor device, a handheld device, or a vehicle-mounted device. The scenario in which the network device and the terminal device are deployed is not limited in the embodiment of the present application.

[0178] In an embodiment of the present application, the terminal device 101 or the network device 102 includes a hardware layer, an operating system layer running on the hardware layer, and an application layer running on the operating system layer. The hardware layer includes hardware such as a central processing unit (CPU), a memory management unit (MMU), and a memory (also called a main memory). The operating system may be any one or more types of computer operating systems that implement service processing through processes, for example, a Linux operating system, a Unix operating system, an Android operating system, an iOS operating system, or a Windows operating system. The application layer includes applications such as a browser, an address book, a word processing software, and an instant messaging software.

[0179] In an embodiment of the present application, the apparatus configured to implement the functions of the network device may be the network device 101, or may be an apparatus, such as a chip system, that can support the network device in implementing the functions. The apparatus may be installed in the network device.

[0180] The technical solutions provided in the embodiments of the present application are applied to wireless communication between communication devices. The wireless communication between communication devices may include wireless communication between a network device 102 and a terminal device 101, wireless communication between network devices, and wireless communication between terminals. In the embodiments of the present application, the term "wireless communication" may be shortened to "communication", and the term "communication" may be shortened to "data transmission", "information transmission", or "transmission".

[0181] Figure 2 is a diagram of an example of an application scenario according to an embodiment of the present application. As shown in Figure 2, the application scenario may include a network device 210, a network device 220, and a terminal device 230. The terminal device 230 includes an antenna panel 231 and an antenna panel 232. In any implementation, in the application scenario shown in Figure 2, the network device 210 and the network device 220 may be two base stations. The network device 210 and the network device 220 may alternatively be two transmission / reception points TRP of one base station.

[0182] It should be understood that the application scenario may include multiple terminal devices and multiple network devices. There may be multiple antenna panels in the terminal device 230. This is not limited in the embodiment of the present application.

[0183] In implementation, when a network device configures multiple SRS resource sets for a terminal device, the terminal device may determine an antenna panel corresponding to an uplink transmission and determine an SRS resource in the SRS resource set by receiving an SRS resource indicator (SRI) transmitted by the network device to transmit precoding. The precoding may be digital beamforming and / or precoding, or beamforming and / or precoding, or digital and analog hybrid beamforming and precoding.

[0184] In implementation, a network device may configure one or more SRS resource sets for a terminal device. One SRS resource set may include one or more SRS resources. One SRS resource may include an SRS resource ID, a quantity of SRS ports, an SRS time domain type indicator, an SRS periodicity, a time-frequency resource location of the SRS within one slot, etc.

[0185] In the implementation, when the transmission mode is codebook (CB)-based uplink transmission, the network device may configure multiple SRS resource sets for the terminal device. Each SRS resource set includes one or more SRS resources, and the terminal device transmits the SRS resources in each SRS resource set to the network device. Each SRS resource corresponds to one uplink channel. The network device learns different uplink channel qualities based on the received SRS resources. The network device selects an SRS resource based on the uplink channel quality and indicates the SRS resource to the terminal device. The network device transmits an SRI, a transmitted precoding matrix indicator (TPMI), and a transmitted rank indication (TRI) to the terminal device. The SRI indicates the SRS resource selected by the network device, and the terminal device may determine the SRS resource selected by the network device based on the received SRI. The terminal device transmits a physical uplink share channel (PUSCH) in a beam direction in which the SRS resource was previously transmitted. In this specification, transmitting a PUSCH may be understood as transmitting data on a PUSCH. The terminal device may further determine an antenna panel or an antenna port for transmitting a PUSCH in an uplink transmission process based on an SRS resource. TPMI indicates a precoding matrix used when a PUSCH is transmitted. TRI indicates a rank (a quantity of ranks) used when a PUSCH is transmitted.

[0186] Optionally, in the case of a codebook-based uplink transmission mode, each SRS resource set includes up to two SRS resources, and each SRS resource is a multi-port SRS resource. In the implementation of the present application, the SRS resource may be referred to as a channel. In the implementation of the present application, the channel may be a transmission link. For example, as shown in FIG. 2, the network device 210 and / or the network device 220 configure two SRS resource sets for the terminal device 230, namely, the #1 SRS resource set and the #2 SRS resource set. Each SRS resource set in FIG. 2 corresponds to one network device. The #1 SRS resource set includes two resources, namely, channel 1 and channel 2 shown in FIG. 2. In this specification, the channel 1 may be referred to as the SRS resource 1, and the channel 2 may be referred to as the SRS resource 2. The #2 SRS resource set includes two resources, namely, channel 3 and channel 4 shown in FIG. 2. In this specification, the channel 3 may be referred to as the SRS resource 3, and the channel 4 may be referred to as the SRS resource 4.

[0187] In the application scenario of FIG. 2, the terminal device 230 has two antenna panels 231 and 232, and the terminal device may transmit four SRS resources to the network device via the two antenna panels. FIG. 2 shows that the terminal device transmits SRS resource 1 and SRS resource 3 via panel 231, and the terminal device transmits SRS resource 2 and SRS resource 4 via panel 232. When the network device indicates the selected SRS resource to the terminal device, the terminal device may determine the antenna panel corresponding to the SRS resource to determine which antenna panel is for transmitting the PUSCH. For example, when the network device indicates to the terminal device that the selected SRS resource is SRS resource 1, the terminal device may determine that the antenna panel corresponding to the SRS resource 1 is antenna panel 231. Thus, the terminal device may determine to transmit the PUSCH via panel 231. In this specification, transmitting a PUSCH may be understood as transmitting a transport block.

[0188] 2 shows an example in which each SRS resource set includes two SRS resources. In an optional implementation, each SRS resource set may further include only one SRS resource.

[0189] In implementation, when the uplink transmission is a non-codebook (NCB) based uplink transmission, the network device may configure multiple SRS resource sets for the terminal device. Unlike the case of CB based uplink transmission, in the NCB based uplink transmission mode, each SRS resource set includes up to four SRS resources, and each SRS resource is a single-port SRS resource.

[0190] It should be understood that the present application is applicable to codebook-based or non-codebook-based uplink transmission modes. Figure 2 shows a codebook-based uplink transmission scenario. Figure 2 is just an example for illustration purposes. This is not a limitation in the present application.

[0191] It can be understood that the network device may select one or more SRS resources and indicate the one or more SRS resources to the terminal device, and the terminal device transmits a PUSCH to the network device on the one or more SRS resources indicated by the network device. The terminal device may transmit the PUSCH to the network device on the one or more SRS resources in different transmission modes.

[0192] Optionally, in an embodiment of the present application, one PUSCH may include one or more transport blocks, and one antenna panel may transmit one transport block or a portion of one transport block.

[0193] Optionally, in an embodiment of the present application, a network device may use one SRI to indicate one SRS resource to a terminal device, and a network device may use multiple SRIs to indicate multiple SRS resources to a terminal device, where each SRI indicates one SRS resource.

[0194] Optionally, in an embodiment of the present application, the terminal device transmitting a transport block to the network device via the antenna panel specifically refers to the terminal device transmitting the transport block to the network device through one or more demodulation reference signals (DMRS) on the antenna panel.

[0195] The following describes three modes in the embodiment of the present application.

[0196] The three modes in the embodiment of the present application include a first mode, a second mode, and a third mode.

[0197] First mode

[0198] The first mode is a transmission mode in which the terminal device transmits a transport block to the network device by using one antenna panel, or a transmission mode in which the terminal device transmits a transport block to the network device via one antenna panel, or a transmission mode in which the terminal device transmits a transport block to the network device on one antenna panel. For example, the terminal device 230 transmits one transport block to the network device 210 by using the antenna panel 231. Alternatively, the terminal device 230 transmits one transport block to the network device 210 and the network device 220 by using the antenna panel 231.

[0199] In a possible implementation, the first mode may alternatively be expressed as transmitting a transport block based on one SRS resource set configuration by using one antenna panel. Specifically, the first mode means that the network device configures one SRS resource set for the terminal device, and the terminal device transmits a transport block to the network device by using one antenna panel. In this case, the mode is the first mode. For example, as shown in FIG. 2, when the SRS resource set configured by the network device for the terminal device is the #1 SRS resource set, the first mode may be understood to be that the terminal device 230 transmits a transport block to the network device 210 by using the antenna panel 231, or that the terminal device 230 transmits a transport block to the network device 210 by using the antenna panel 232.

[0200] Optionally, in an embodiment of the present application, the first mode may alternatively be understood to be transmitting a transport block on one antenna panel based on one SRS resource indicated by one SRI. For example, as shown in FIG. 2, when a network device indicates SRS resource 1 to a terminal device by using one SRI, the terminal device transmits a transport block to the network device 210 on the antenna panel 231 through channel 1. In this specification, there may be a collocation relationship between the SRS resource indicated by the SRI and the DMRS port for transmitting the transport block on the antenna panel. Therefore, the first mode may alternatively be understood to be transmitting a transport block based on one collocation relationship.

[0201] Optionally, the first mode may also be referred to as a single transmission mode.

[0202] Second Mode

[0203] The second mode is a transmission mode in which the terminal device transmits the same transport block at at least two instants by using at least one antenna panel, the transport block being transmitted at each of the at least two instants by using one antenna panel, or the second mode is a transmission mode in which the terminal device transmits the same transport block at at least two instants via at least one antenna panel, the transport block being transmitted at each of the at least two instants via one antenna panel, or the second mode is a transmission mode in which the terminal device transmits the same transport block at at least two instants on at least one antenna panel, the transport block being transmitted at each of the at least two instants on one antenna panel.

[0204] For example, terminal device 230 transmits one transport block to network device 210 at a first moment by using antenna panel 231, and then terminal device 230 transmits the same transport block to network device 220 at a second moment by using antenna panel 232, where the first moment is different from the second moment.

[0205] In another example, the terminal device 230 transmits one transport block to the network device 210 at a first moment by using the antenna panel 231, and then the terminal device 230 transmits the same transport block to the network device 220 at a second moment by using the antenna panel 231, where the first moment is different from the second moment.

[0206] In another example, the terminal device 230 transmits one transport block to the network device 210 at a first moment by using the antenna panel 231, and then the terminal device 230 transmits the same transport block to the network device 210 at a second moment by using the antenna panel 232, where the first moment is different from the second moment.

[0207] In this specification, the same transport block means that the information or data carried in two or more transport blocks is the same.

[0208] In the above description of the second mode, the instants may be understood as time units. Correspondingly, the first and second instants may be understood as the first and second time units. In this case, the second mode may be understood as a transmission mode for transmitting the same transport block in at least two time units by using at least one antenna panel, the transport block being transmitted in each of the at least two time units by using one antenna panel. In this case, the first and second time units do not overlap.

[0209] It should be understood that a time unit in an embodiment of the present application may be one or more symbols, one or more slots, one or more mini-slots, one or more frames, one or more subframes, or one or more half-frames.

[0210] In a possible implementation, the second mode may alternatively be expressed as transmitting a transport block in each of at least two time units via one antenna panel based on the configuration of multiple SRS resource sets, where the at least two time units do not overlap. Specifically, the second mode means that the network device configures multiple SRS resource sets for the terminal device, and the terminal device transmits a transport block in at least two time units, and transmits the transport block to the network device in each time unit by using one antenna panel, where the two time units do not overlap. In this case, the mode is the second mode.

[0211] For example, as shown in FIG. 2, when the SRS resource sets configured by the network device for the terminal device are #1 SRS resource set and #2 SRS resource set, the terminal device 230 transmits one transport block to the network device 210 in a first time unit by using antenna panel 231, and then the terminal device 230 transmits a transport block to the network device 220 in a second time unit by using antenna panel 232, where the first time unit is different from the second time unit.

[0212] In another example, when the SRS resource sets configured by the network device for the terminal device are #1 SRS resource set and #2 SRS resource set, the terminal device 230 transmits one transport block to the network device 210 in a first time unit by using the antenna panel 231, and then the terminal device 230 transmits a transport block to the network device 220 in a second time unit by using the antenna panel 231, where the first time unit is different from the second time unit.

[0213] In another example, when the SRS resource sets configured by the network device for the terminal device are #1 SRS resource set and #2 SRS resource set, the terminal device 230 transmits one transport block to the network device 210 in a first time unit by using the antenna panel 231, and then the terminal device 230 transmits the same transport block to the network device 210 in a second time unit by using the antenna panel 232, where the first time unit is different from the second time unit.

[0214] Optionally, in an embodiment of the present application, the second mode may alternatively be understood to be transmitting a transport block in each of at least two time units based on SRS resources indicated by multiple SRIs via one antenna panel, where a transport block is transmitted in each time unit based on one SRS resource. For example, as shown in FIG. 2, when a network device indicates SRS resource 1 and SRS resource 4 to a terminal device by using two SRIs, the terminal device transmits a transport block to the network device 210 on the antenna panel 231 through channel 1 in the first time unit, and then the terminal device transmits a transport block to the network device 220 on the antenna panel 232 through channel 4 in the second time unit. In this specification, there may be a collocation relationship between the SRS resources indicated by the SRIs and the DMRS ports for transmitting the transport block on the antenna panel. Therefore, the second mode may alternatively be understood to be transmitting a transport block in at least two time units based on multiple collocation relationships.

[0215] Optionally, the second mode may be referred to as an alternating transmission mode.

[0216] Third mode

[0217] The third mode may be a transmission mode in which the same transport block is transmitted simultaneously by using at least two antenna panels on the terminal device, with different antenna panels transmitting different parts of the transport block, or the third mode may be a transmission mode in which one transport block is transmitted simultaneously by using each of the at least two antenna panels, or The third mode may be a transmission mode in which the same transport block is transmitted simultaneously via at least two antenna panels, with different antenna panels transmitting different portions of the transport block, or the third mode may be a transmission mode in which one transport block is transmitted simultaneously via each of the at least two antenna panels.

[0218] For example, antenna panel 231 and antenna panel 232 transmit the same transport block simultaneously, where antenna panel 231 and antenna panel 232 transmit different parts of the same transport block, or antenna panel 231 and antenna panel 232 on terminal device 230 each transmit one transport block simultaneously.

[0219] In a third mode, the terminal device may transmit the transport block to the same network device or may transmit the transport block to different network devices by using a multi-antenna panel.

[0220] For example, terminal device 230 transmits a portion of a transport block to network device 210 by using antenna panel 231, and the terminal device transmits another portion of the transport block to network device 210 by using antenna panel 232.

[0221] In another example, terminal device 230 transmits a portion of a transport block to network device 210 by using antenna panel 231, and the terminal device transmits another portion of the transport block to network device 220 by using antenna panel 232.

[0222] In another example, the terminal device 230 transmits one transport block to the network device 210 by using the antenna panel 231, and the terminal device transmits another transport block to the network device 210 by using the antenna panel 232.

[0223] In another example, terminal device 230 transmits one transport block to network device 210 by using antenna panel 231, and the terminal device transmits another transport block to network device 220 by using antenna panel 232.

[0224] Optionally, in the embodiment of the present application, the third mode may alternatively be understood to be simultaneously transmitting a transport block on at least two antenna panels based on SRS resources indicated by multiple SRIs, where a transport block is transmitted on each antenna panel based on one SRS resource. For example, as shown in FIG. 2, when a network device indicates SRS resource 1 and SRS resource 4 to a terminal device by using two SRIs, the terminal device transmits a transport block to the network device 210 on the antenna panel 231 through channel 1, and the terminal device transmits the transport block to the network device 220 on the antenna panel 232 through channel 4. In this specification, there may be a collocation relationship between the SRS resources indicated by the SRIs and the DMRS ports for transmitting the transport block on the antenna panels. Therefore, the third mode may alternatively be understood to be simultaneously transmitting a transport block on at least antenna panels based on multiple collocation relationships.

[0225] It should be understood that in the third mode of the embodiment of the present application, "simultaneous" may be understood as the existence of a set of intersections between time units at which at least two antenna panels on a terminal device transmit a transport block to a network device, or "simultaneous" may be understood as the same moment in time.

[0226] Optionally, the third mode may be referred to as a simultaneous transmission mode.

[0227] Optionally, in a scenario in which a multi-antenna panel is configured for a terminal device, when the terminal device transmits a transport block to a network device, the first mode and the second mode are supported. The network device may be a transmission / reception point in this specification.

[0228] Optionally, in a scenario where a multi-antenna panel is configured for a terminal device, the third mode is not supported when the terminal device transmits a transport block to a network device. The network device may be a transmission / reception point in this specification.

[0229] Optionally, in a scenario where a multi-antenna panel is configured for a terminal device, when the terminal device transmits a transport block to multiple network devices, the first mode, the second mode, and the third mode are supported. The network device may be a transmission / reception point in this specification.

[0230] It may be understood that in each transmission mode, the terminal device transmits a transport block to the network device on one or more SRS resources indicated by the network device.

[0231] In the first mode, the network device may indicate one or more SRS resources to the terminal device. As shown in FIG. 2, the network device may indicate one SRS resource, for example, SRS resource 1, SRS resource 2, SRS resource 3, or SRS resource 4, to the terminal device, or the network device may indicate two SRS resources, for example, SRS resource 1 and SRS resource 3, or SRS resource 2 and SRS resource 4, to the terminal device. Thus, the first mode corresponds to six channel group sets. The terminal device transmits a transport block on the SRS resource indicated by the network device by using one antenna panel.

[0232] In the second mode, the network device may indicate two SRS resources to the terminal device. The terminal device transmits a transport block to the network device at a first moment and a second moment by using one antenna panel. At each moment, the terminal device may transmit a transport block to the network device on one of the two SRS resources on one antenna panel. When two SRS resource sets are configured for the terminal device, each SRS resource set includes two SRS resources, and the second mode may include multiple channel group sets. Similarly, the third mode also includes multiple channel group sets.

[0233] Table 1 shows channel group sets corresponding to the three transmission modes of the CB-based uplink transmission communication scenario shown in FIG.

[0234] [Table 1]

[0235] As shown in Table 1, when the transmission mode is the first mode, there are six channel group sets in total, and the channel group sets are numbered from 1 to 6.

[0236] The channel group set corresponding to the first mode may include two sub-modes, namely, a first mode 1 and a first mode 2. The first mode 1 includes four channel group sets numbered 1 through 4. For example, as shown in FIG. 2, when the first mode corresponds to number 2 of the first mode 1, the antenna panel 232 on the terminal device 230 may transmit a transport block to the network device 210 through channel 2. The first mode 2 includes two channel group sets numbered 5 and 6. For example, as shown in FIG. 2, when the first mode corresponds to number 5 of the first mode 2, the antenna panel 231 on the terminal device 230 may transmit one transport block to each of the network device 210 and the network device 220 through channel 1 and channel 3.

[0237] When the transmission mode is the second mode, there are a total of 12 channel group sets, and the channel group sets corresponding to the second mode may include three sub-modes, namely, second mode 1, second mode 2, and second mode 3. The second mode 1 includes four channel group sets numbered 7 to 10. For example, as shown in FIG. 2, when the second mode corresponds to number 7 of the second mode 1, the antenna panel 231 on the terminal device 230 transmits one transport block to the network device 210 at a first moment through channel 1, and the antenna port 232 on the terminal device 230 transmits the same transport block to the network device 220 at a second moment through channel 4, where the first moment is different from the second moment. The second mode 2 includes four channel group sets numbered 11 to 14. For example, as shown in FIG. 2, when the second mode corresponds to the number 11 of the second mode 2, the antenna panel 232 on the terminal device 230 transmits one transport block to the network device 220 at a first moment through channel 4, and the antenna panel 231 on the terminal device 230 transmits the same transport block to the network device 210 at a second moment through channel 1, where the first moment is different from the second moment. The second mode 3 includes four channel group sets numbered 15 to 18. For example, as shown in FIG. 2, when the second mode corresponds to the number 15 of the second mode 3, the antenna panel 231 on the terminal device 230 transmits one transport block to the network device 210 at a first moment through channel 1, and the antenna panel 232 on the terminal device 230 transmits the same transport block to the network device 210 at a second moment through channel 2, where the first moment is different from the second moment. It should be noted that in the second mode, each channel group set illustrates an example in which two channels are included, and the two channels represent a sequence in which the terminal device transmits transport blocks to the network device.For example, for a channel group set numbered 7, the channel group set includes channel 1 and channel 4. In this case, the terminal device first transmits a transport block to the network device over channel 1, and then transmits the transport block to the network device over channel 4. For example, for a channel group set numbered 11, the channel group set includes channel 4 and channel 1. In this case, the terminal device first transmits a transport block to the network device over channel 4, and then transmits the transport block to the network device over channel 1.

[0238] When the transmission mode is the third mode, there are four channel group sets in total, and the channel group set corresponding to the third mode may include two sub-modes, namely, the third mode 1 and the third mode 2. The third mode 1 includes two channel group sets numbered 19 and 20. For example, as shown in FIG. 2, when the third mode corresponds to the number 20 of the third mode 1, the antenna panel 231 and the antenna panel 232 on the terminal device 230 transmit the same transport block to the network device 220 through the channel 3 and the channel 4, respectively, where the antenna panel 231 and the antenna panel 232 transmit different parts of the transport block. Alternatively, the channel group set corresponding to the number 20 may be understood as the antenna panel 231 and the antenna panel 232 on the terminal device 230 each simultaneously transmit one transport block to the network device 220 through the channel 3 and the channel 4, respectively. The third mode 2 includes two channel group sets numbered 21 and 22. 2, when the third mode corresponds to number 21 of the third mode 1, antenna panel 231 on terminal device 230 and antenna panel 232 on terminal device 230 transmit the same transport block to network device 210 and network device 220 through channel 1 and channel 4, respectively, where antenna panel 231 and antenna panel 232 transmit different portions of the transport block. Alternatively, the channel group set corresponding to number 21 may be understood as antenna panel 231 on terminal device 230 transmitting one transport block to network device 210 through channel 1, and antenna panel 232 transmitting one transport block to network device 220 through channel 4.

[0239] FIG. 3 is a schematic flowchart of a communication method according to an embodiment of the present application.

[0240] S301: A network device sends first information to a terminal device.

[0241] Specifically, the first information indicates one mode or two modes, where the one mode is one of the first mode, the second mode, or the third mode, and the two modes are two of the first mode, the second mode, or the third mode.

[0242] For example, in an implementation, by receiving first information transmitted by a network device, it may be determined that the transmission mode of the antenna panel at the terminal device side is one mode out of three modes, or the first information may further indicate that the transmission mode of the antenna panel at the terminal device side is two modes out of three modes.

[0243] In the implementation, the first information may be one bit. Optionally, the bit is carried in radio resource control (RRC) information, medium access control control element (MAC CE), or downlink control information (DCI). Specifically, the value of the bit may indicate an antenna panel at the terminal device side for selecting one mode or two modes of the three modes.

[0244] For example, the first information is one bit in the DCI, and when the first value of the bit in the DCI is 1, the first information indicates two modes, the two modes being a first mode and a second mode, or when the second value of the bit in the DCI is 0, the first information indicates one mode, the mode being a third mode.

[0245] In another example, the first information is one bit in the DCI, and when a first value of the bit in the DCI is 1, the first information indicates two modes, the two modes being the first mode and the second mode, or when a second value of the bit in the DCI is 0, the first information indicates two modes, the two modes being the first mode and the third mode. In another example, the first information is one bit in the DCI, and when a first value of the bit in the DCI is 1, the first information indicates two modes, the two modes being the first mode and the third mode, or when a second value of the bit in the DCI is 0, the first information indicates one mode, the mode being the second mode.

[0246] The above description simply uses an example where the first value is 1 and the second value is 0. It can be understood that the first value may be 0 and the second value may be 1.

[0247] When the first information is a first value, the first information indicates any one or two of the three modes. When the first information is a second value, the first information indicates one or two of the three modes that are not completely the same as the one or two modes. This is not limited to this embodiment of the present application, and details will not be described in this specification.

[0248] In implementation, the first information may be 2 bits. Optionally, when the first information is 2 bits, the first indication may directly indicate one mode. The 2 bits may be carried in RRC information, MAC CE, or DCI.

[0249] S302: The terminal device transmits a transport block in a transmission mode indicated by the first information or one of two transmission modes indicated by the first information.

[0250] Optionally, when the first information indicates one mode, the terminal device transmits the transport block in the mode indicated by the first information, or when the first information indicates two modes, the terminal device transmits the transport block in one of the two modes indicated by the first information.

[0251] Optionally, when the first information indicates two modes, the method may include step S303: the network device sends second information to the terminal device, where the second information is used to indicate the mode of the two modes.

[0252] For example, when the first information indicates that the transmission modes of the antenna panel on the terminal device are the first mode and the third mode, the terminal device may transmit the transport block in the first mode or the third mode, or the terminal device may receive second information transmitted by the network device, where the second information indicates whether the mode used by the terminal device is the first mode or the third mode.

[0253] In an implementation, the second information may be at least one bit in an RRC, MAC CE, or DCI. For example, when the first information indicates that the transmission mode of the antenna panel on the terminal device is a first mode and a second mode, and the second information is two bits configured in the DCI, the value of the two bits configured in the DCI may further indicate whether the transmission mode of the antenna panel on the terminal device is the first mode or the second mode.

[0254] Specifically, the transmission mode of the antenna panel on the terminal device and indicated by the second information transmitted by the network device is that mode of the two modes determined by the terminal device based on the first information.

[0255] Optionally, in this embodiment of the present application, the first information indicates one or two modes from the plurality of modes, where the plurality of modes includes one or more of the first mode, the second mode, or the third mode, and the method of this embodiment of the present application further includes a step of receiving third information, where the third information indicates whether the plurality of modes includes the third mode.

[0256] Optionally, the third information may be an RRC, a MAC CE, or a DCI.

[0257] Optionally, the third information includes the first field, and when a value of the first field is a third value, the third information indicates that the plurality of modes includes the third mode, or when a value of the first field is a fourth value, the third information indicates that the plurality of modes does not include the third mode. For example, the third value may be 0 and the fourth value is 1, or the third value is 1 and the fourth value is 0.

[0258] Optionally, whether the plurality of modes includes the third mode may be determined based on whether the third information includes the first field. For example, when the third information includes the first field, the plurality of modes includes the third mode, or when the third information does not include the first field, the plurality of modes does not include the third mode. As another example, when the third information includes the first field, the plurality of modes does not include the third mode, or when the third information does not include the first field, the plurality of modes includes the third mode.

[0259] FIG. 4 is a schematic flowchart of another example of a communication method according to an embodiment of the present application.

[0260] S401: A network device sends first information to a terminal device.

[0261] Specifically, the first information is used to determine a target mode from the at least two modes, where the at least two modes include at least two of a first mode, a second mode, or a third mode.

[0262] S402: A terminal device transmits a transport block in a target mode.

[0263] The following provides four optional implementations for the embodiment of FIG.

[0264] Implementation 1: The at least two modes may be two modes, and the two modes may be a first mode and a third mode, or the two modes may be a second mode and a third mode, or the two modes may be a first mode and a second mode. In this case, the first information indicates one mode from the two modes, and the mode is a target mode. In this case, the first information may be one bit, and different values ​​in the bit indicate one mode or another mode of the two modes. The bit may be carried in an RRC, a MAC CE, or a DCI.

[0265] Implementation 2: The at least two modes may be three modes, and the three modes include a first mode, a second mode, and a third mode. In this case, the first information is used to determine a target mode from the three modes, and the target mode is one of the three modes. In Implementation 2, the content indicated by the first information may include two cases.

[0266] Case 1: The first piece of information directly indicates one of three modes.

[0267] Case 2: The first piece of information indicates two modes out of three.

[0268] In this implementation, the first information indicates one mode or two modes, the one mode being the first mode, the second mode, or the third mode, and the two modes being two modes of the first mode, the second mode, or the third mode. When the first information has different values, the first information can indicate one mode or two modes. When the first information is one bit and the bit has different values, the first information can indicate one mode or two modes of the three modes. When the first information is two bits, the first information can directly indicate one mode. The first information of this implementation is the same as the first information of the embodiment of FIG. 3, and the details are not described again in this specification.

[0269] Optionally, as in the embodiment of Figure 3, when the first information indicates two modes, the terminal device may determine one of the two modes as the target mode, or when the first information indicates two modes, the method may further include the following step: S403: the terminal device receives second information, where the second information indicates the mode among the two modes, and the mode is the target mode. The description of the second information is the same as that of the embodiment of Figure 3, and the details are not described again in this specification.

[0270] Optionally, the method of this embodiment of the present application further includes a step of receiving third information, where the third information indicates whether the at least two modes includes a third mode.

[0271] Optionally, the third information may be an RRC, a MAC CE, or a DCI.

[0272] Optionally, the third information includes the first field, and when the value of the first field is a third value, the third information indicates that the at least two modes include the third mode, or when the value of the first field is a fourth value, the third information indicates that the at least two modes do not include the third mode. For example, the third value may be 0 and the fourth value is 1, or the third value is 1 and the fourth value is 0.

[0273] Optionally, whether the at least two modes include the third mode may be determined based on whether the third information includes the first field. For example, when the third information includes the first field, the at least two modes include the third mode, or when the third information does not include the first field, the at least two modes do not include the third mode. In another example, when the third information includes the first field, the at least two modes do not include the third mode, or when the third information does not include the first field, the at least two modes include the third mode.

[0274] FIG. 5 is a schematic flowchart of another example of a communication method according to an embodiment of the present application.

[0275] S501: A network device transmits first information to a terminal device, and the terminal device receives the first information transmitted by the network device.

[0276] The first information is used by the terminal device to determine N modes from the M modes, where N is an integer greater than 0 and M is an integer greater than or equal to N.

[0277] The M modes include one or more of a first mode, a second mode, or a third mode.

[0278] In a possible implementation, the value of M is 2. When the value of M is 2, the value of N may be 1. In this case, the first information is used to determine one transmission mode from two transmission modes. In this case, it can be understood that this embodiment is the same as implementation 1 in the embodiment of FIG. 4.

[0279] In another optional implementation, the value of M is 3. The value of N may be 1, or the value of N may be 2.

[0280] When the value of M is 3 and the value of N is 1, in this case, the present embodiment is the same as Case 1 of Implementation 2 in the embodiment of FIG.

[0281] When the value of M is 3 and the value of N is 2, in this case, this embodiment is the same as Case 2 of Implementation 2 in the embodiment of FIG.

[0282] For details, please refer to the description of the embodiment in Figure 4 and Figure 3. The details will not be described again here.

[0283] It may be understood that M and N may alternatively have other values, for example, the value of M may be 4, 5, 6, or another possible positive integer value, and N may be any positive integer value less than or equal to M.

[0284] S502: A terminal device transmits a transport block in one of N transmission modes.

[0285] Optionally, the same as in the embodiment of Fig. 3, when the first information indicates two modes, the terminal device may determine one of the two modes as a target mode, or when the first information indicates two modes, the method may further include S503. The terminal device receives second information, where the second information indicates one of the two modes, and the mode is the target mode. The description of the second information is the same as the description of the second information in the embodiment of Fig. 3, and the details are not described again in this specification.

[0286] Optionally, the method in this embodiment of the present application further includes a step of receiving third information, where the third information indicates whether the M modes include a third mode.

[0287] Optionally, the third information may be an RRC, a MAC CE, or a DCI.

[0288] Optionally, the third information includes the first field, and when a value of the first field is a third value and the third information indicates that the M modes include the third mode, or when a value of the first field is a fourth value, the third information indicates that the M modes do not include the third mode. For example, the third value may be 0 and the fourth value is 1, or the third value is 1 and the fourth value is 0.

[0289] Optionally, whether the M modes include the third mode may also be determined based on whether the third information includes the first field. For example, when the third information includes the first field, the M modes include the third mode, or when the third information does not include the first field, the M modes do not include the third mode. In another example, when the third information includes the first field, the M modes do not include the third mode, or when the third information does not include the first field, the M modes include the third mode.

[0290] FIG. 6 is a schematic flowchart of another example of a transmission method according to an embodiment of the present application.

[0291] S601: A network device transmits first information to a terminal device, and the terminal device receives the first information transmitted by the network device.

[0292] S602: The terminal device determines one mode or N modes based on the first information, where the one mode is one of the M modes, and the N modes are N modes of the M modes, N is an integer greater than 1, and M is an integer greater than or equal to N.

[0293] The M modes include at least one or more of a first mode, a second mode, and a third mode.

[0294] In a possible implementation, the value of M may be 2. In this case, the terminal device may determine one mode from two modes based on the first information. Alternatively, it may be understood that the first information indicates one mode from two modes. In this case, it may be understood that this embodiment is the same as implementation 1 in the embodiment of FIG. 4.

[0295] In a possible implementation, the value of M may be 3. In this case, the terminal device may determine one mode or N modes from the three modes based on the first information, where N may be equal to 2.

[0296] When the terminal device determines one mode from three modes based on the first information, in this case, in the present embodiment, please refer to Case 1 of Implementation 2 in the embodiment of Figure 4. When the terminal device determines N modes from three modes based on the first information, where N=2, in this case, in the present embodiment, please refer to Case 2 of Implementation 2 in the embodiment of Figure 4.

[0297] It may be understood that M and N may alternatively have other values, for example, the value of M may be 4, 5, 6, or another possible positive integer value, and N may be any positive integer value less than or equal to M.

[0298] S603: The terminal device transmits a transport block in one mode or one of N modes.

[0299] Optionally, the same as in the embodiment of Fig. 3, when the first information indicates two modes, the terminal device may determine one of the two modes as a target mode, or when the first information indicates two modes, the method may further include: The terminal device receives second information, where the second information indicates one of the two modes, and the mode is the target mode. The description of the second information is the same as the description of the second information in the embodiment of Fig. 3, and the details are not described again in this specification.

[0300] Optionally, the method in this embodiment of the present application further includes receiving third information, where the third information indicates whether the M modes include a third mode.

[0301] Optionally, the third information may be an RRC, a MAC CE, or a DCI.

[0302] Optionally, the third information includes the first field, and when a value of the first field is a third value, the third information indicates that the M modes include the third mode, or when a value of the first field is a fourth value, the third information indicates that the M modes do not include the third mode. For example, the third value may be 0 and the fourth value is 1, or the third value is 1 and the fourth value is 0.

[0303] Optionally, whether the M modes include the third mode may also be determined based on whether the third information includes the first field. For example, when the third information includes the first field, the M modes include the third mode, or when the third information does not include the first field, the M modes do not include the third mode. In another example, when the third information includes the first field, the M modes do not include the third mode, or when the third information does not include the first field, the M modes include the third mode.

[0304] The technical solutions in the embodiments of Figures 3 to 6 will not be described in detail below.

[0305] 7 to 9 show three examples in which the first information indicates the transmission mode of an antenna panel on a terminal device when the first information is one bit in an RRC, MAC CE, or DCI.

[0306] FIG. 7 is a block diagram of an example of a communication method according to an embodiment of the present application.

[0307] In Figure 7, the first information is one bit. When the first information is a first value, the first information indicates two modes, the two modes being a first mode and a second mode; or when the first information is a second value, the first information indicates one mode, the mode being a third mode.

[0308] When the value of the bit in the RRC, MAC CE, or DCI is 0, the first information indicates the third mode.

[0309] In one implementation, the terminal device may determine the channel group set in the third mode by receiving the fourth information. For example, the fourth information may be two SRI fields in the DCI, each SRI field corresponding to one bit. In the codebook-based uplink transmission scenario shown in FIG. 2, when the value of the first information, i.e., the bit in the RRC, MAC CE, or DCI, indicates the third mode, the correspondence between the value of the fourth information and the channel group set in the third mode is shown in Table 2.

[0310] [Table 2]

[0311] It can be learned from the above Table 2 that when the first information is 1 bit in the DCI and the value of the bit in the DCI that is 0 indicates the third mode, the value of the fourth information, i.e., two SRI fields in the DCI, may indicate a specific channel group set in the third mode. For example, when the fourth information is two SRI fields in the DCI, each SRI field corresponds to 1 bit, the value of the bit in the #1 SRI field in the DCI is 0, and the value of the bit in the #2 SRI field in the DCI is 0, the channel group set is channel 1 and channel 2. In this case, please refer to FIG. 2, and in the scenario shown in FIG. 2, the terminal device may determine that channel 1 corresponds to antenna panel 231 and channel 2 corresponds to antenna panel 232. Therefore, this can be understood as antenna panel 231 on terminal device 230 and antenna panel 232 on terminal device 230 simultaneously transmitting the same transport block to network device 210 through channel 1 and channel 2, respectively, in a channel group set in the third mode, with antenna panel 231 and antenna panel 232 transmitting different portions of the transport block, or antenna panel 231 on terminal device 230 and antenna panel 232 on terminal device 230 simultaneously transmitting one transport block to network device 210 through channel 1 and channel 2, respectively.

[0312] It should be understood that the correspondence between the value of the bit in each SRI field and the channel group set in the third mode in Table 2 is an example, which is not limited to this embodiment of the present application.

[0313] Alternatively, when the value of the bit in the RRC, MAC CE, or DCI is 1, it indicates that the transmission modes of the antenna panels on the terminal device are the first mode and the second mode.

[0314] In one implementation, when the value of the bit in the RRC, MAC CE, or DCI is 1, it indicates that the transmission mode of the antenna panel on the terminal device is the first mode and the second mode. The terminal device may transmit the transport block in the first mode or the second mode. Alternatively, the terminal device may receive second information, where the second information indicates whether the transmission mode is the first mode or the second mode. The second information may be at least one bit in the RRC, MAC CE, or DCI. For example, the second information may be two bits configured in the DCI. It should be understood that the value of the second information may be understood as a value of two bits configured in the DCI.

[0315] In one implementation, in the application example scenario of FIG. 2, the second information may indicate whether the transmission mode of the antenna panel on the terminal device is the first mode or the second mode by using two bits configured in the DCI. Optionally, the second information may further indicate a sub-mode of the first mode or a sub-mode of the second mode. For example, the second information is two bits configured in the DCI, and when the value of the second information is 00, it indicates the first sub-mode 1 of the first mode, or when the value of the second information is 01, it indicates the first sub-mode 2 of the first mode. For example, the correspondence between the value of the second information and the sub-mode is not limited in this application.

[0316] In one implementation, the terminal device may further determine the channel group set in the first mode or the second mode by receiving the fourth information. For example, the fourth information is two bits in the DCI, and the two SRI fields carried in the DCI occupy one bit each. In the codebook-based uplink transmission scenario shown in FIG. 2, when the value of the first information, i.e., the bit in the RRC, MAC CE, or DCI that is 1, indicates that the transmission mode of the antenna panel on the terminal device is the first mode and the second mode, the terminal device may receive the second information and the fourth information transmitted by the network device and indicating the channel group set in the first mode and the second mode, as shown in Table 3.

[0317] [Table 3]

[0318] Please refer to Table 3. The first and fifth columns of Table 3 indicate the value of the second information, and the value of the second information may be two bits. As shown in Table 3, the value of the second information may be 00, 01, 10, and 11. The second and third columns of Table 3 are the values ​​of the two SRI fields, respectively, and the sixth and seventh columns are the values ​​of the two SRI fields, respectively. As shown in Table 3, for each value of the second information, the two SRI fields may have up to four values, which are 00, 01, 11, and 10, respectively.

[0319] It can be learned from Table 3 that when the second information, which is two bits in the DCI, indicates one of the first mode and the second mode, the value of the fourth information (i.e., the two SRI fields in the DCI) may further indicate a channel group set in the first mode and the second mode.

[0320] As shown in Table 3, when the value of the second information, i.e., the two bits in the DCI, are 00 and 01, it indicates that the transmission mode of the antenna panel on the terminal device is the first mode. When the value of the second information is 00, it corresponds to the first mode 1 of the submode of the first mode, and when the value of the second information is 01, it corresponds to the first mode 2 of the submode of the first mode. When the value of the second information, i.e., the two bits in the DCI, are 10 and 11, it indicates that the transmission mode of the antenna panel on the terminal device is the second mode. When the value of the second information is 10, it corresponds to the second mode 1 of the submode of the second mode, and when the value of the second information is 11, it corresponds to the second mode 2 of the submode of the second mode.

[0321] It should be understood that Table 3 shows 8 channel group sets among 12 channel group sets in the second mode as an example, which is not limited in this embodiment of the present application.

[0322] For example, in the scenario shown in Figure 2, when the value of the second information, i.e., two bits in the DCI, is 10, the value of one bit in the #1 SRI field carried in the fourth information, i.e., DCI, is 0, the value of one bit in the #2 SRI field is 1, and the channel group set in the second mode is channel 1 and channel 3. In this case, it can be understood that the antenna panel 231 on the terminal device 230 transmits one transport block to the network device 210 at a first moment through channel 1, and the antenna panel 231 on the terminal device 230 transmits the same transport block to the network device 220 at a second moment through channel 3, where the first moment is different from the second moment.

[0323] In one implementation, based on the communication scenario of Table 3, the terminal device may further receive second information and fourth information transmitted by the network device indicating channel group sets in the first mode and the second mode, as shown in Table 4.

[0324] [Table 4]

[0325] It should be understood that, unlike those in Table 3, in Table 4, when the value of the second information, i.e., two bits in the DCI, are 00 and 01, the channel group set in the first mode may be determined based on the value of the fourth information, i.e., one bit of one SRI field in the DCI. In this case, the fourth information, i.e., the #2 SRI field in the DCI, is not used. When the value of the second information is 00, it indicates that the channel group set in the first mode is channel 1 or channel 2. When the value of the fourth information is 01, it indicates that the channel group set in the third mode is channel 1 or channel 2. Furthermore, the steps and specific processes of determining the channel groups in the first mode and the second mode in Table 4 may be similar to those in Table 3. In order to avoid repetition, their detailed description is omitted here.

[0326] For example, when the value of the second information is 00, the second information indicates the first mode, and when the value of the fourth information is 0, the fourth information indicates channel 1 in the first mode. In this case, the terminal device transmits a transport block to the network device 210 on the antenna panel 231 through channel 1.

[0327] For example, when the value of the second information is 10, the second information indicates the second mode, and when the value of the fourth information is 00, it indicates that the channel group set is channel 1 and channel 4. In this case, the terminal device 230 transmits a transport block to the network device 210 at a first moment through channel 1 on the antenna panel 231, and then the terminal device 230 transmits the same transport block to the network device 220 at a second moment through channel 4 on the antenna panel 232.

[0328] It should be understood that the correspondence between the values ​​of the second information in Table 3 and Table 4, the values ​​of the two SRI fields in the fourth information, and the channel group sets in the first mode and the second mode is an example, which is not limited in this embodiment of the present application.

[0329] FIG. 8 is a block diagram of another example of a communication method according to an embodiment of the present application.

[0330] In Fig. 8, the first information is 1 bit. When the first information is a first value, the first information indicates two modes, and the two modes are a first mode and a second mode; or when the first information is a second value, the first information indicates two modes, and the two modes are a first mode and a third mode.

[0331] The terminal device receives first information sent by the network device, where the first information may be a bit in an RRC, a MAC CE, or a DCI.

[0332] When the value of the bit in the RRC, MAC CE, or DCI is 0, it indicates that the transmission mode of the antenna panel on the terminal device is the first mode and the third mode.

[0333] In one implementation, when the value of the bit in the RRC, MAC CE, or DCI is 0, it indicates that the transmission modes of the antenna panels on the terminal device are the first mode and the third mode. The terminal device may transmit the transport block in the first mode or the third mode. Alternatively, the terminal device may receive second information, where the second information indicates whether the transmission mode is the first mode or the third mode. The second information may be at least one bit in the RRC, MAC CE, or DCI. For example, the second information may be two bits in the DCI.

[0334] In one implementation, the terminal device may further determine the channel set or channel group set in the first mode and the third mode by receiving the fourth information. In the codebook-based uplink transmission scenario shown in FIG. 2, when the value of the first information, i.e., the bit in the RRC, MAC CE, or DCI that is 0, indicates that the transmission mode of the antenna panel on the terminal device is the first mode and the third mode, the terminal device may receive the second information and the fourth information transmitted by the network device and indicating the channel group set in the first mode and the third mode, as shown in Table 5.

[0335] [Table 5]

[0336] Please refer to Table 5. The first and fifth columns of Table 5 indicate the value of the second information, and the value of the second information may be two bits. As shown in Table 5, the value of the second information may be 00, 01, 10, and 11. The second and third columns of Table 5 are the values ​​of the two SRI fields, respectively, and the sixth and seventh columns are the values ​​of the two SRI fields, respectively. As shown in Table 5, for each value of the second information, the two SRI fields may have up to four values, which are 00, 01, 11, and 10, respectively.

[0337] It can be learned from Table 5 that when the second information, which is two bits in the DCI, indicates one of the first mode and the third mode, the value of the fourth information, i.e., the two SRI fields in the DCI, may indicate a channel group set in the first mode and the third mode.

[0338] As shown in Table 5, when the value of the second information, i.e., the two bits in the DCI, are 00 and 01, it indicates that the transmission mode of the antenna panel on the terminal device is the first mode. When the value of the second information is 00, it indicates the first mode 1 of the submodes of the first mode, and when the value of the second information is 01, it indicates the first mode 2 of the submodes of the first mode. When the value of the second information, i.e., the two bits in the DCI, is 10, it indicates that the transmission mode of the antenna panel on the terminal device is the third mode. When the value of the second information is 11, the four channel group set here is in a reserved state.

[0339] 2, when the value of the second information, i.e., two bits in the DCI, is 10, the value of one bit in the #1 SRI field in the fourth information is 1, the value of one bit in the #2 SRI field is 1, and the channel group set in the third mode is channel 3 and channel 4. In this case, it can be understood as the antenna panel 231 on the terminal device 230 and the antenna panel 232 on the terminal device 230 simultaneously transmitting the same transport block to the network device 220 through channel 3 and channel 4, respectively, where the antenna panel 231 and the antenna panel 232 transmit different parts of the transport block, or the antenna panel 231 on the terminal device 230 and the antenna panel 232 on the terminal device 230 simultaneously transmitting one transport block to the network device 220 through channel 3 and channel 4, respectively.

[0340] In this implementation, in the two sub-modes of the first mode, the first mode 1 and the first mode 2 can be understood to indicate the following meanings: the first mode 1 indicates that one antenna panel on the terminal device transmits a transport block to the network device through one channel, and the first mode 2 indicates that one antenna panel on the terminal device transmits a transport block to the network device through two channels.

[0341] In one implementation, based on the communication scenario of Table 5, the terminal device receives second information and fourth information transmitted by the network device, indicating channel group sets in the first mode and the third mode, as shown in Table 6.

[0342] [Table 6]

[0343] It should be understood that, unlike that of Table 5, in Table 6, when the value of the second information, i.e., two bits in the DCI, are 00 and 01, the channel group set in the first mode may be determined based on the value of the fourth information, i.e., one bit of one SRI field in the DCI. In this case, the fourth information, i.e., the #2 SRI field in the DCI, is not used. When the value of the second information is 00, it indicates that the channel group set in the first mode is channel 1 or channel 2. When the value of the fourth information is 01, it indicates that the channel group set in the third mode is channel 1 or channel 2. Furthermore, the specific process of determining the channel groups in the first mode and the third mode in Table 6 may be similar to that of Table 5. In order to avoid repetition, their detailed description is omitted here.

[0344] It should be understood that the correspondence between the values ​​of the second information in Table 5 and Table 6, the values ​​of the two SRI fields in the fourth information, and the channel group sets in the first mode and the third mode is an example, which is not limited in this embodiment of the present application.

[0345] Alternatively, a value of the bit in the RRC, MAC CE, or DCI indicates the first mode and the second mode when the value is 1. Optionally, one of the first mode and the second mode may be further indicated by the second information. Optionally, a value of the fourth information may further indicate a channel group set in the first mode or the second mode.

[0346] FIG. 9 is a block diagram of yet another example of a communication method according to an embodiment of the present application.

[0347] In Figure 9, the first information is one bit. When the first information is a first value, the first information indicates two modes, the two modes being the first mode and the third mode; or when the first information is a second value, the first information indicates one mode, the mode being the second mode.

[0348] The terminal device receives first information sent by the network device, where the first information may be a bit in an RRC, a MAC CE, or a DCI.

[0349] A value of 0 for the bit in the RRC, MAC CE, or DCI indicates the second mode.

[0350] In one implementation, the terminal device may determine a channel group set in the second mode by receiving the fourth information. In the codebook-based uplink transmission scenario shown in FIG. 2, when the value of the first information, i.e., the bit in the RRC, MAC CE, or DCI, indicates the second mode, the terminal device may receive the fourth information, which is transmitted by the network device and indicates a channel group set in the third mode, as shown in Table 7. It should be understood that Table 7 shows, as an example, four channel group sets among the twelve channel group sets in the second mode. This is not limited in this embodiment of the present application.

[0351] [Table 7]

[0352] It can be learned from Table 7 that when the first information is one bit in the DCI and the value of the bit in the DCI being 0 indicates a second mode out of the three modes, the channel group set in the second mode can be indicated by the value of the fourth information, i.e., two SRI fields in the DCI. For example, when the fourth information is two SRI fields in the DCI and the value of one bit in the #1 SRI in the DCI is 0 and the value of one bit in the #2 SRI in the DCI is 0, in the scenario shown in FIG. 2, the channel group set in the second mode can be understood as the antenna panel 231 on the terminal device 230 transmitting one transport block to the network device 210 at a first moment through channel 1 and the antenna panel 232 on the terminal device 230 transmitting the same transport block to the network device 220 at a second moment through channel 4, where the first moment is different from the second moment.

[0353] It should be understood that the value of the fourth information, i.e., the correspondence between the two SRI fields in the DCI and the channel group set in the second mode in Table 7, is an example, which is not limited in this embodiment of the present application.

[0354] Alternatively, when the value of the bit in the RRC, MAC CE, or DCI is 1, it indicates that the transmission modes of the antenna panel on the terminal device are the first mode and the third mode. Optionally, one of the first mode and the third mode may be indicated by the second information. Optionally, the value of the fourth information may further indicate a channel group set in the first mode or the third mode.

[0355] 7 to 9 show cases where the first information is 1 bit in a multi-antenna panel scenario. The mode used by the terminal device to transmit the transport block can be determined by using the first information.

[0356] In one possible implementation, the first information may be 2 bits. In this case, the first information may directly indicate one mode. Optionally, the terminal device may further determine a channel group set corresponding to each mode by receiving the fourth information.

[0357] In the codebook-based uplink transmission scenario shown in Figure 2, when the first information, which is two bits in the DCI, indicates that the transmission mode of the antenna panel on the terminal device is the first mode, the second mode, or the third mode, the terminal device may receive the fourth information, which is transmitted by the network device and indicates the channel group set in the first mode, the second mode, or the third mode, as shown in Table 8. It should be understood that Table 8 shows, as an example, four of the six channel group sets in the first mode, four of the twelve channel sets in the second mode, and four channel group sets in the third mode. This is not limited in this embodiment of the present application.

[0358] [Table 8]

[0359] Table 8 is a schematic table showing the first information being the first mode, the second mode or the third mode when the first information is 2 bits in the embodiment in Figures 3 to 6. The first and fifth columns of Table 8 show the value of the first information, and the value of the first information can be 2 bits. As shown in Table 8, the value of the first information can be 00, 01, 10 and 11.

[0360] It can be learned from Table 8 that when the first information, which is two bits in the DCI, indicates one mode in the first mode, the second mode, or the third mode, the channel group set in the first mode, the second mode, or the third mode can be further indicated by the value of the fourth information, i.e., two SRI fields in the DCI. As shown in Table 8, when the value of the two bits of the first information is 00, it indicates the first mode, when the value of the two bits of the first information is 01, it indicates the third mode, or when the value of the two bits of the first information is 10 and 11, it indicates the second mode. When the value of the first information is 10, it corresponds to the second mode 1 of the submode of the second mode, and when the value of the second information is 11, it corresponds to the second mode 2 of the submode of the second mode. It should be understood that Table 8 shows 8 channel group sets in the 12 channel group sets in the second mode as an example. This is not limited in this embodiment of the present application.

[0361] 2, when the value of the first information, i.e., two bits in the DCI, is 11, the value of the fourth information, i.e., one bit in the #1 SRI field in the DCI, is 0, and the value of one bit in the #2 SRI field is 1, and the channel group set in the second mode indicated by the fourth information is channel 2 and channel 4. In this case, it can be understood that the antenna panel 232 on the terminal device 230 transmits a transport block to the network device 210 at a first moment through channel 2, and the antenna panel 232 on the terminal device 230 transmits the same transport block to the network device 220 at a second moment through channel 4, where the first moment is different from the second moment.

[0362] In the example of Table 8, the second mode includes two sub-modes, a second mode 1 and a second mode 2. The second mode 1 includes four channel group sets. The terminal device 230 first transmits a transport block to the network device 210, and then transmits the transport block to the network device 220 in the four channel group sets. The second mode 2 includes four channel group sets. The terminal device 230 first transmits a transport block to the network device 220, and then transmits the transport block to the network device 210 in the four channel group sets. Thus, the first mode 1 and the second mode 2 respectively represent a sequence in which the terminal device transmits a transport block to the network device.

[0363] In one implementation, based on the communication scenario of Table 8, the terminal device receives fourth information indicating a channel group set in the first mode, the second mode, or the third mode transmitted by the network device as shown in Table 9.

[0364] [Table 9]

[0365] It should be understood that the channel group sets included in two sub-modes of the second mode in Table 9 are different from those in Table 8. The second mode in Table 9 includes two sub-modes, a second mode 1 and a second mode 3. The second mode 3 includes four channel group sets, and the antenna panel 231 and the antenna panel 232 on the terminal device 230 continuously transmit a transport block to the network device 210 or continuously transmit a transport block to the network device 220 in the four channel group sets.

[0366] In one implementation, based on the communication scenario of Table 9, the terminal device receives fourth information indicating a channel group set in the first mode, the second mode, or the third mode transmitted by the network device as shown in Table 10.

[0367] [Table 10]

[0368] It should be understood that the channel group set included in the first mode in Table 10 is different from that in Table 9.

[0369] It should be further understood that the correspondence between the values ​​of the first information in Tables 8 to 10, the values ​​of the two SRI fields in the fourth information, and the channel group sets in the first mode, the second mode, and the third mode is an example, which is not limited in this embodiment of the present application.

[0370] In an optional implementation, in the technical solutions of Tables 8 to 10, when the first information is 2 bits, whether the mode indicated by the first information is the first mode, the second mode, or the third mode can be determined by determining the value set to which the value of the first information belongs.

[0371] For example, in Table 8, the first value set may be defined as {00}. In other words, the first value set includes a value, and the value is 00. When the value of the first information is 00, the value of the first information is considered to belong to the first value set. In this case, the first information indicates a first mode. The terminal device may determine one mode based on the first information, and the mode is the first mode, and thus the terminal device transmits a transport block in the first mode.

[0372] In Table 8, the second value set may be defined as {10,11}. In other words, the second value set includes two values, and the two values ​​are 10 and 11. When the value of the first information is 10 or 11, the value of the first information is considered to belong to the second value set. In this case, the first information indicates a second mode. The terminal device may determine one mode based on the first information, and the mode is the second mode, and therefore the terminal device transmits a transport block in the second mode.

[0373] In Table 8, the second value set may be defined as {01}. In other words, the second value set includes values, and the values ​​are 01. When the value of the first information is 01, the value of the first information is considered to belong to the third value set. In this case, the first information indicates a third mode. The terminal device may determine one mode based on the first information, and the mode is the third mode, and therefore the terminal device transmits a transport block in the third mode.

[0374] Table 9 and Table 10 are not described in detail herein by using examples. It can be understood that in Table 9 and Table 10, the first value set, the second value set and the third value set are only examples for explanation. This is not limited in the embodiment of the present application.

[0375] According to the technical solutions of Tables 9 and 10, the two bits configured in the DCI can be used as the first information to specifically indicate one of the first mode, the second mode, or the third mode. In addition, the channel group set in each transmission mode is further determined based on the values ​​of the two SRI fields in the received fourth information sent by the network device. This solves the problem of indicating the transmission mode of the multi-antenna panel at the terminal device side without increasing the bit overhead.

[0376] In this application, an example is used in which the communication device is the terminal device in the above method embodiment. Figure 10 is a diagram of the structure of a terminal device 1000. The terminal device 1000 may include a transceiver module 1010 and a processing module 1020.

The first information is at least two bits in an RRC, MAC CE, or DCI.

[0384] Optionally, the transceiver module 1010 is further configured to receive third information before receiving the first information, where the third information indicates whether the M modes include the third mode.

[0385] In detail, the third information includes a first field, and when a value of the first field is a third value, the third information indicates that the M modes include the third mode, or when a value of the first field is a fourth value, the third information indicates that the M modes do not include the third mode.

The first field is a field in an RRC, a MAC CE, or a DCI.

[0391] In this application, an example is used in which the communication device is a network device in the above method embodiment. Figure 11 is a block diagram of a communication device according to an embodiment of the present application. As shown in Figure 11, the communication device 1100 may include a sending module 1110 and a receiving module 1120.

This is not limited to the embodiments of the present application.

[0410] In some embodiments, an embodiment of the present application further provides a communication device. The communication device includes an interface circuit and a logic circuit. The interface circuit is configured to input and / or output information. The logic circuit is configured to perform the method in any one of the above method embodiments and to process and / or generate output information based on the input.

[0412] In another possible product form, the network device and the terminal device in the embodiment of the present application may be implemented in a common bus architecture. Figure 12 is a diagram of the structure of a communication device 1200 according to one embodiment of the present application. The communication device 1200 includes a processor 1201 and a transceiver 1202. The communication device 1200 may be a network device or a terminal device or a chip in a network device or a terminal device. Figure 12 shows only the main components of the communication device 1200. In addition to the processor 1201 and the transceiver 1202, the communication device may further include a memory 1203 and an input / output device (not shown in Figure 12).
