[0192] Among them, the terminal 11 involved in the embodiment of the present application may be a device that provides voice and / or data connectivity to the user, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem. In different systems, the name of the terminal may also be different. For example, in a 5G system, the terminal may be called a user equipment (UE). A wireless terminal can communicate with one or more core networks (CN) via a radio access network (RAN). The wireless terminal can be a mobile terminal, such as a mobile phone (or a "cellular" phone) and a computer with a mobile terminal. For example, it can be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges language and / or data with a radio access network. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDA), Redcap terminals and other devices. A wireless terminal may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, and a user device, but is not limited thereto in the embodiments of the present application.

[0193] The network device 12 involved in the embodiment of the present application may be a base station, which may include multiple cells providing services for the terminal. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in the access network that communicates with the wireless terminal through one or more sectors on the air interface, or other names. The network device may be used to interchange received air frames with Internet Protocol (IP) packets, and serve as a router between the wireless terminal and the rest of the access network, wherein the rest of the access network may include an Internet Protocol (IP) communication network. The network device may also coordinate the attribute management of the air interface. For example, the network device involved in the embodiments of the present application may be a network device (Base Transceiver Station, BTS) in the Global System for Mobile communications (Global System for Mobile communications, GSM) or Code Division Multiple Access (Code Division Multiple Access, CDMA), or a network device (NodeB) in Wide-band Code Division Multiple Access (WCDMA), or an evolutionary network device (evolutional Node B, eNB or e-NodeB) in the long term evolution (long term evolution, LTE) system, a 5G base station (gNB) in the 5G network architecture (next generation system), a base station in 6G, or a home evolved Node B (Home evolved Node B, HeNB), a relay node, a home base station (femto), a pico base station (pico), etc., which is not limited in the embodiments of the present application. In some network structures, the network device may include a centralized unit (CU) and a distributed unit (DU), and the centralized unit and the distributed unit may also be arranged geographically separately.

[0194] In the embodiment of the present application, the network device and the terminal can each use one or more antennas for multiple input multiple output (MIMO) transmission, and the MIMO transmission can be single user MIMO (SU-MIMO) or multi-user MIMO (MU-MIMO). According to the form and number of antenna combinations, MIMO transmission can be two-dimensional MIMO (2D-MIMO), three-dimensional MIMO (3D-MIMO), full-dimensional MIMO (FD-MIMO) or massive MIMO, and can also be diversity transmission, precoded transmission, beamforming transmission, etc.

[0195] Before describing the embodiments of the present application, the following briefly introduces the related technologies:

[0196] 1. Duplex Mode

[0197] The fifth generation new wireless system (5th Generation New RAT, 5G NR) supports time division duplex (TDD) and frequency division duplex (FDD). The TDD mode is to send and receive at different times on the same frequency channel, that is, the carrier, and distinguish the uplink and downlink transmission resources by time. The FDD mode sends and receives on different frequency channels at the same time, and distinguishes the uplink and downlink transmission resources by frequency.

[0198] 5G NR will support SBFD in the Rel-18 stage, that is, the base station can simultaneously transmit and receive in different subbands within a frequency band / carrier / BWP, and the subbands used for transmission and reception do not overlap. An SBFD symbol is a symbol that contains both a subband for uplink transmission (referred to as uplink SBFD subband) and a subband for downlink transmission (referred to as downlink SBFD subband).

[0199] 2. Semi-static SBFD and dynamic SBFD

[0200] Semi-static SBFD: SBFD subband resources are semi-statically configured. The transmission direction in the subband does not change dynamically. In the uplink SBFD subband, only uplink transmission is possible, but downlink reception is not possible. In the downlink SBFD subband, only downlink reception is possible, but uplink transmission is not possible. All base stations and UEs use the same semi-static SBFD configuration. Figure 2As shown, the base station and the terminal have the same understanding of the resources of the SBFD symbols.

[0201] Dynamic SBFD: Dynamic SBFD may be implemented in multiple ways. One implementation is to semi-statically configure SBFD subband resources, but the transmission direction within the subband can change dynamically. The base station needs to instruct the terminal on the transmission direction within the subband.

[0202] For SBFD, in order not to increase the implementation complexity of UE, semi-static SBFD on the UE side and dynamic SBFD on the base station side can be considered. Specifically, the semi-static SBFD configurations of different UEs are different, which results in the transmission direction of some symbols changing dynamically from the perspective of the base station. Figure 3 As shown in the figure, in time slot n+1 (i.e. slot n+1), UE-1 and UE-2 have different understandings of the transmission direction of the resources, which may lead to conflicts. To address this problem, base station scheduling can be used to avoid conflicts between different terminals, but this has great restrictions on base station configuration and affects the flexibility of base station configuration. In order to avoid conflicts between different terminals, it is also possible to define that the UE does not transmit the configured uplink transmission or does not receive the configured downlink transmission on all SBFD symbols, but this has a great impact on the configured channel, resulting in a loss of UE transmission performance.

[0203] In view of this, an embodiment of the present application proposes a solution for a UE to determine a transmission mode of an SBFD subband based on a base station configuration or indication. The following describes the transmission determination method, transmission indication method, terminal and network device provided in the embodiment of the present application in conjunction with the accompanying drawings.

[0204] See also Figure 4 , Figure 4 is a flow chart of a transmission determination method provided by an embodiment of the present application. Figure 4 As shown, the transmission determination method includes the following steps:

[0205] Step 401: The terminal receives a first message from a network device, where the first message includes first information, where the first information is used to indicate a transmission mode of at least part of SBFD subbands of N time domain units, where N is an integer greater than 1 or equal to 1;

[0206] Step 402: The terminal determines, based on the first information, whether to use a first SBFD subband of a first time domain unit for first transmission, the N time domain units including the first time domain unit;

[0207] Wherein, when the first transmission is an uplink transmission, the first SBFD sub-band is an uplink SBFD sub-band;

[0208] When the first transmission is downlink transmission, the first SBFD sub-band is a downlink SBFD sub-band.

[0209] In the embodiment of the present application, the transmission conflict can be understood as, for the same SBFD subband of the same time domain unit, one terminal or some terminals (represented by UE-1) understand it as an uplink SBFD subband and perform uplink transmission on the subband, and another terminal or some other terminals (represented by UE-2) understand it as a downlink SBFD subband and perform downlink transmission on the subband. In this way, a transmission conflict occurs when uplink transmission and downlink transmission are performed simultaneously on the same SBFD subband.

[0210] In order to avoid transmission conflicts between different UEs due to inconsistent understanding of the transmission direction of the SBFD subband, in an embodiment of the present application, the network device indicates to UE-1 through a first message the transmission mode that UE-1 needs to adopt on certain specific SBFD subbands in certain specific time domain units. For UE-2, the network device may indicate to UE-2 through a second message the transmission mode that UE-2 needs to adopt on certain specific SBFD subbands in the time domain unit. Alternatively, the network device does not indicate to UE-2 the transmission mode that it needs to adopt, so that UE-2 can transmit according to its own understanding. The network device can flexibly indicate (or configure) a specific transmission mode for UE-1 (and UE-2) based on the transmission requirements of UE-1 and UE-2.

[0211] For example, for the transmission (or non-dynamic transmission) configured by the terminal, the transmission mode may include two types: allowing transmission and not allowing transmission, or two types: allowing transmission and not being able to transmit. The time domain unit may include, for example, a symbol, a time slot, and the like.

[0212] Taking the case where UE-1 and UE-2 have different understandings of the transmission direction of the first SBFD subband of the first time domain unit (e.g., UE-1 understands the first SBFD subband of the first time domain unit as an uplink SBFD subband, i.e., the transmission direction is uplink, and UE-2 understands the first SBFD subband of the first time domain unit as a downlink SBFD subband, i.e., the transmission direction is downlink) as an example, the indication method of the network device may include the following situations:

[0213] Case 1: The network device indicates the transmission mode of the first SBFD subband in the first time domain unit to UE-1 through a first message, and indicates the transmission mode of the first SBFD subband in the first time domain unit to UE-2 through a second message. In this case, the network device indicates different transmission modes to the two terminals respectively. For example, for the transmission (or non-dynamic transmission) configured for UE-1 and the transmission (or non-dynamic transmission) configured for UE-2, the network device can indicate to UE-1 that transmission is allowed in the first SBFD subband in the first time domain unit, and indicate to UE-2 that transmission is not allowed in the first SBFD subband in the first time domain unit. This can avoid transmission conflicts between UE-1 and UE-2 due to inconsistent understanding of the transmission direction of the first SBFD subband in the first time domain unit by UE-1 and UE-2.

[0214] Case 2: The network device indicates the transmission mode of the first SBFD subband in the first time domain unit to UE-1 through the first message, and does not indicate the transmission mode of the first SBFD subband in the first time domain unit to UE-2. In this case, UE-2 can decide the transmission in the first SBFD subband of the first time domain unit according to its own understanding, and the network device indicates to UE-1 a transmission mode that does not conflict with the transmission of UE-2. This can avoid transmission conflicts between UE-1 and UE-2 due to inconsistent understanding of the transmission direction of the first SBFD subband of the first time domain unit by UE-1 and UE-2.

[0215] In an embodiment of the present application, a terminal receives a first message from a network device, the first message includes first information, and the first information is used to indicate the transmission mode of at least part of the SBFD subbands of N time domain units; the terminal determines whether to use the first SBFD subband of the first time domain unit for the first transmission based on the first information. Through the above process, the terminal can determine whether to use the SBFD subband for the first transmission based on the indication of the network device, so as to avoid transmission conflicts between different UEs due to different UEs' understanding of the transmission direction of the SBFD subband.

[0216] In some embodiments, the method further comprises:

[0217] In a case where the terminal determines not to use the first SBFD subband of the first time domain unit for the first transmission, the terminal abandons the first transmission, or the terminal performs the first transmission in a second SBFD subband of another available time domain unit;

[0218] Wherein, when the first transmission is an uplink transmission, the second SBFD sub-band is an uplink SBFD sub-band;

[0219] When the first transmission is downlink transmission, the second SBFD sub-band is a downlink SBFD sub-band.

[0220] Here, the terminal performs the first transmission in the second SBFD subband of other available time domain units. For example, the terminal performs the first transmission in the second SBFD subband of the next available time domain unit.

[0221] In some embodiments, the first transmission is a non-dynamic transmission.

[0222] In this implementation, considering that the transmission requirements of dynamic transmission are higher (such as higher requirements for transmission timeliness) and the transmission requirements of non-dynamic transmission are lower, the network device can indicate (or configure) the transmission mode for the non-dynamic transmission that the terminal needs to transmit in the SBFD sub-band, thereby reducing the impact on the terminal transmission performance.

[0223] Non-dynamic transmission may include, for example, semi-persistent transmission, periodic transmission, repeated transmission, multi-slot transmission, and the like.

[0224] In some embodiments, the type of the first transmission includes at least one of the following:

[0225] Semi-persistent transmission configured by Radio Resource Control (RRC) signaling;

[0226] Semi-persistent transmission activated by the Medium Access Control (MAC) Control Element (CE);

[0227] A non-initial transmission based on semi-persistent transmission activated by downlink control information (DCI);

[0228] Non-first transmission based on repeated transmission scheduled by DCI;

[0229] Non-first transmission based on multi-slot transmission scheduled by DCI.

[0230] It should be noted that the first transmission of semi-persistent transmission based on DCI activation, the first transmission of repeated transmission based on DCI scheduling, and the first transmission of multi-slot transmission based on DCI scheduling can be regarded as dynamic transmission. The terminal can perform the above first transmission normally in the corresponding SBFD subband according to its own understanding.

[0231] In some embodiments, the transmission mode indicated by the first information includes at least one of the following:

[0232] The first transmission mode allows uplink transmission in the uplink SBFD subband;

[0233] The second transmission mode does not allow uplink transmission in the uplink SBFD subband;

[0234] The third transmission mode allows downlink transmission in the downlink SBFD subband;

[0235] The fourth transmission mode does not allow downlink transmission in the downlink SBFD subband.

[0236] The transmission mode indicated by the network device through the first information can be a transmission mode exclusive to the terminal, or it can be a transmission mode exclusive to the first configuration. The first configuration is used to perform transmission configuration on the terminal. The first configuration can be, for example, a configuration authorization (Configured Grant, CG), semi-persistent scheduling (Semi-Persistent Scheduling, SPS) and other configurations.

[0237] In some embodiments, the first information includes at least one of the following:

[0238] Information used to indicate a full time domain set, where the full time domain set includes all SBFD time domain units configured for the terminal;

[0239] Information used to indicate a first time domain set, wherein a transmission mode corresponding to an uplink SBFD subband of a time domain unit in the first time domain set is the first transmission mode;

[0240] Information used to indicate a second time domain set, wherein the transmission mode corresponding to the uplink SBFD subband of the time domain unit in the second time domain set is the second transmission mode;

[0241] Information used to indicate a third time domain set, wherein the transmission mode corresponding to the downlink SBFD subband of the time domain unit in the third time domain set is the third transmission mode;

[0242] Information used to indicate a fourth time domain set, wherein the transmission mode corresponding to the downlink SBFD subband of the time domain unit in the fourth time domain set is the fourth transmission mode.

[0243] Taking the time domain unit as a symbol as an example, the indication methods of the network device may specifically include the following:

[0244] Method 1: configure the full set of semi-static SBFD symbols (ie, the full time domain set), and configure some of the SBFD symbols as set 1 (ie, the first time domain set). The terminal can determine set 2 (ie, the second time domain set) based on the full set and set 1.

[0245] Further, some SBFD symbols in the full set may be configured as set three (i.e., the third time domain set), and the terminal may determine set four (i.e., the fourth time domain set) based on the full set and set three. Alternatively, some SBFD symbols in the full set may be configured as set four, and the terminal may determine set three based on the full set and set four.

[0246] Method 2: configure the entire set of semi-static SBFD symbols, and configure some of the SBFD symbols as set 2. The terminal may determine set 1 based on the entire set and set 2.

[0247] Further, some SBFD symbols in the full set may be configured as set three, and the terminal may determine set four based on the full set and set three. Alternatively, some SBFD symbols in the full set may be configured as set four, and the terminal may determine set three based on the full set and set four.

[0248] Method three: configure some SBFD symbols as set one, and configure another part of SBFD symbols as set two.

[0249] Furthermore, some SBFD symbols may be configured as set three, and another part of SBFD symbols may be configured as set four.

[0250] Mode 4: configure the full set of semi-static SBFD symbols, and configure some of the SBFD symbols as set 3. The terminal may determine set 4 based on the full set and set 3.

[0251] Mode 5: configure the full set of semi-static SBFD symbols, and configure some of the SBFD symbols as set 4. The terminal may determine set 3 based on the full set and set 4.

[0252] Method six: configure some SBFD symbols as set three, and configure another part of SBFD symbols as set four.

[0253] The terminal may adopt the first transmission mode in the uplink SBFD subband of the SBFD symbols included in set one, adopt the second transmission mode in the uplink SBFD subband of the SBFD symbols included in set two, adopt the third transmission mode in the uplink SBFD subband of the SBFD symbols included in set three, and adopt the fourth transmission mode in the uplink SBFD subband of the SBFD symbols included in set four.

[0254] In this implementation, the network device indicates the correspondence between the SBFD subband and the transmission mode of each time domain unit by configuring the time domain set. This indication method is simple and clear and can efficiently indicate the transmission mode corresponding to the SBFD subband of each time domain unit.

[0255] In some embodiments, the terminal determines, based on the first information, whether to use a first SBFD subband of a first time domain unit for first transmission, including:

[0256] The terminal determines, based on the first information, a time domain set to which the first time domain unit belongs;

[0257] The terminal determines, according to the time domain set to which the first time domain unit belongs, whether to use the first SBFD subband of the first time domain unit for the first transmission.

[0258] In this implementation manner, the terminal may determine whether to use a certain SBFD subband of a certain time domain unit for transmission according to the time domain set to which the time domain unit belongs.

[0259] In some embodiments, the terminal determines, according to the time domain set to which the first time domain unit belongs, whether to use the first SBFD subband of the first time domain unit for the first transmission, including any of the following:

[0260] When the first time domain unit belongs to the first time domain set and the first transmission is an uplink transmission configured in the first time domain unit, the terminal determines to use a first SBFD subband of the first time domain unit for the first transmission;

[0261] When the first time domain unit belongs to the second time domain set and the first transmission is an uplink transmission configured in the first time domain unit, the terminal determines not to use a first SBFD subband of the first time domain unit for the first transmission;

[0262] When the first time domain unit does not belong to the first time domain set and the first transmission is an uplink transmission configured in the first time domain unit, the terminal determines not to use the first SBFD subband of the first time domain unit for the first transmission;

[0263] When the first time domain unit does not belong to the second time domain set and the first transmission is an uplink transmission configured in the first time domain unit, the terminal determines to use a first SBFD subband of the first time domain unit for the first transmission;

[0264] When the first time domain unit belongs to the third time domain set and the first transmission is a downlink transmission configured in the first time domain unit, the terminal determines to use a first SBFD subband of the first time domain unit for the first transmission;

[0265] When the first time domain unit belongs to the fourth time domain set and the first transmission is a downlink transmission configured in the first time domain unit, the terminal determines not to use the first SBFD subband of the first time domain unit for the first transmission;

[0266] When the first time domain unit does not belong to the third time domain set and the first transmission is a downlink transmission configured in the first time domain unit, the terminal determines not to use the first SBFD subband of the first time domain unit for the first transmission;

[0267] When the first time domain unit does not belong to the fourth time domain set and the first transmission is a downlink transmission configured in the first time domain unit, the terminal determines to use a first SBFD subband of the first time domain unit for the first transmission.

[0268] In order to better understand the technical solutions of the embodiments of the present application, specific embodiments are provided below for illustrative purposes.

[0269] Embodiment 1: Uplink transmission cannot be configured in the uplink SBFD subband

[0270] like Figure 5 As shown, the terminal is configured with an uplink SBFD subband and / or a downlink SBFD subband in time slots n+1, n+2, and n+3 and is configured to use different transmission modes. The specific configuration modes include the following two modes (the effects achieved are the same, but there are differences in the configuration modes):

[0271] Mode 1: The terminal is configured to include uplink SBFD subbands in time slots n+1, n+2, and n+3, and does not perform semi-statically configured uplink transmission in the uplink SBFD subband of the configured time slot n+1.

[0272] Method 2: The terminal is configured with an uplink SBFD subband in time slot n+1 and does not perform semi-statically configured uplink transmission in the uplink SBFD subband of time slot n+1, and is configured with an uplink SBFD subband in time slots n+2 and n+3 and can perform semi-statically configured uplink transmission in the uplink SBFD subband of time slots n+2 and n+3.

[0273] Then, in the uplink SBFD subband of time slot n+1, if there is a semi-statically configured uplink transmission, the terminal does not send the semi-statically configured transmission. Further, if the semi-statically configured uplink transmission in the uplink SBFD subband of time slot n+1 is a repeated transmission or a multi-slot transmission, the transmission opportunity is discarded in time slot n+1 or the transmission opportunity is delayed to other available time slots. In the uplink SBFD subbands of time slots n+2 and n+3, if there is a semi-statically configured uplink transmission, the terminal may send the semi-statically configured transmission.

[0274] Embodiment 2: Downlink transmission configured to be received cannot be received in the downlink SBFD subband

[0275] like Figure 6 As shown, the terminal is configured with an uplink SBFD subband and / or a downlink SBFD subband in time slots n+1, n+2, and n+3 and is configured to use different transmission modes. The specific configuration modes include the following two modes (the effects achieved are the same, but there are differences in the configuration modes):

[0276] Mode 1: The terminal is configured to include downlink SBFD subbands in time slots n+1, n+2, and n+3, and does not receive semi-statically configured downlink transmission in the downlink SBFD subband configured in time slot n+3.

[0277] Method 2: The terminal is configured with a downlink SBFD subband in time slot n+1 and time slot n+2 and can receive semi-statically configured downlink transmission in the downlink SBFD subband, and is configured with a downlink SBFD subband in time slot n+3 and cannot receive semi-statically configured downlink transmission in the downlink SBFD subband.

[0278] Then, in the downlink SBFD subband of time slot n+3, if there is a semi-statically configured downlink transmission, the terminal does not receive the semi-statically configured transmission. Further, if the semi-statically configured uplink transmission in time slot n+3 is a repeated transmission or a multi-slot transmission, the transmission opportunity is discarded in time slot n+3 or the transmission opportunity is delayed to other available time slots, such as the next available time slot. In time slot n+1 and time slot n+2, if there is a semi-statically configured downlink transmission in the downlink SBFD subband, the terminal can receive the semi-statically configured downlink transmission.

[0279] It can be seen from the above embodiments that the transmission method in a duplex system can avoid transmission conflicts between different terminals by supporting the terminal not to transmit configured uplink transmission or not to receive configured downlink transmission in only a part of the semi-statically configured SBFD symbols.

[0280] In summary, in the embodiment of the present application, the terminal can determine whether to use the SBFD subband for the first transmission based on the instruction of the network device, which can avoid different UEs from understanding the transmission direction of the SBFD subband, thereby avoiding transmission conflicts between different UEs.

[0283] Optionally, the transmission mode indicated by the first information includes at least one of the following:

[0301] Based on the first information, determining whether to use a first SBFD subband of a first time domain unit for first transmission, the N time domain units including the first time domain unit;

[0302] Wherein, when the first transmission is an uplink transmission, the first SBFD sub-band is an uplink SBFD sub-band;
