Description

Technical Field

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

[0002] In order to reduce the transmission delay in the time division duplex (TDD) system and enhance the uplink coverage of the TDD system, a subband full duplex (SBFD) scheme is proposed. That is, a section of resources for uplink transmission is configured on the downlink symbols and / or flexible symbols in the TDD system. For example, in the SBFD scheme, a carrier or a bandwidth part (BWP) is divided into multiple subbands, where the subband used to send uplink signals can be called uplink (UL) subband; the subband used to send downlink signals can be called downlink (DL) subband. In order to avoid interference to other terminal devices, the position of the UL subband relative to the DL subband is not fixed.

[0003] During random access by a terminal device, the network device can schedule the transmission of the physical uplink shared channel (PUSCH) using downlink control information (DCI) that carries the uplink grant (UL grant). When using the SBFD scheme for PUSCH transmission, since the location of the UL subband is not fixed, the resources allocated by the network device for the PUSCH may not include the UL subband, which may affect the efficiency of random access by the terminal device and increase the random access latency.

[0125] The technical solution in this application will be described below with reference to the accompanying drawings.

[0126] Figure 1 It is a schematic diagram of a communication system applicable to an embodiment of the present application.

[0127] like Figure 1 As shown, the communication system 10 includes a radio access network (RAN) 100 and a core network (CN) 200. The RAN 100 includes at least one RAN node (e.g., Figure 1 110a and 110b, collectively referred to as 110) and at least one terminal (such as Figure 1 120a-120j in the figure, collectively referred to as 120). The RAN 100 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices ( Figure 1 Terminal 120 is wirelessly connected to RAN node 110. RAN node 110 is wirelessly or wiredly connected to core network 200. The core network equipment in core network 200 and RAN node 110 in RAN 100 can be different physical devices, or they can be the same physical device that integrates core network logical functions and radio access network logical functions.

[0128] The RAN 100 may be a cellular system related to the Third Generation Partnership Project (3GPP), such as a fourth generation (4G) mobile communication system, a fifth generation (5G) mobile communication system, or a future-oriented evolution system (e.g., a sixth generation (6G) mobile communication system). The RAN 100 may also be an open access network (O-RAN or ORAN), a cloud radio access network (CRAN), or a wireless fidelity (WiFi) system. The RAN 100 may also be a communication system that integrates two or more of the above systems.

[0129] The RAN node 110, sometimes also referred to as access network equipment, RAN entity, or access node, constitutes part of the communication system and is used to help terminals achieve wireless access. The multiple RAN nodes 110 in the communication system 10 can be nodes of the same type or different types. In some scenarios, the roles of the RAN node 110 and the terminal 120 are relative, for example, Figure 1 The network element 120i can be a helicopter or a drone, which can be configured as a mobile base station. For the terminals 120j that access the RAN 100 through the network element 120i, the network element 120i is a base station; but for the base station 110a, the network element 120i is a terminal. The RAN node 110 and the terminal 120 are sometimes referred to as communication devices, for example Figure 1 The network elements 110a and 110b can be understood as communication devices with base station functions, and the network elements 120a-120j can be understood as communication devices with terminal functions.

[0130] In one possible scenario, a RAN node may be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a next generation base station in a sixth generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. A RAN node may be a macro base station (e.g. Figure 1 110a in), micro base stations or indoor stations (such as Figure 1 110b in the figure), a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, the RAN node may also be a server, a wearable device, a vehicle or an on-board device, etc. For example, the access network device in the vehicle to everything (V2X) technology may be a road side unit (RSU). All or part of the functions of the RAN node in this application may also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (such as a cloud platform). The RAN node may also be provided with a communication module, circuit or chip that performs the corresponding communication function. The RAN node may also be configured with program instructions for performing the corresponding communication function and corresponding program instructions. The RAN node in this application may also be a logical node, a logical module or software that can implement all or part of the functions of the RAN node.

[0131] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, and different RAN nodes respectively implement part of the functions of the base station. For example, the RAN node can be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU can be set separately, or they can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0132] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (Open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, this application uses CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0133] Terminal 120 can be a device or module that accesses the aforementioned communication system and has corresponding communication functions. A terminal can also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), the Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, smart cities, etc. A terminal can be a mobile phone, tablet computer, computer with wireless transceiver functions, wearable device, vehicle, drone, helicopter, airplane, ship, robot, robotic arm, smart home appliance, transport vehicle with wireless communication functions, communication module, etc. The embodiments of this application do not limit the device form of the terminal. The terminal is typically provided with a communication module, circuit, or chip that performs the corresponding communication functions. The terminal is also configured with program instructions for performing the corresponding communication functions.

[0134] I understand. Figure 1 This is just an example and does not limit the scope of protection of this application. The communication method provided in the embodiment of this application may also involve Figure 1 The network elements not shown in the figure, of course, the communication method provided in the embodiment of the present application may also include only Figure 1 Some network elements are shown.

[0135] In order to facilitate understanding of the technical solutions of the embodiments of the present application, before introducing the solutions of the embodiments of the present application based on this architecture, some terms or concepts that may be involved in the embodiments of the present application are first briefly described.

[0136] 1. Initial bandwidth part (BWP)

[0137] When a UE accesses a cell or a carrier from an idle state, the BWP corresponding to the UE's initial access is called the initial BWP. A cell or a carrier can usually have one or more initial BWPs. That is, the initial BWP can be understood as the BWP configured by the system for initial access, and the identifier (ID) of the BWP is equal to 0. The initial BWP includes an initial uplink BWP (initial UL BWP) and / or an initial downlink BWP (initial DL BWP). The initial UL BWP can be configured by signaling initialUplinkBWP; the initial DL BWP can be configured by signaling initialDownlinkBWP. The initial BWP can be used for the UE's initial access process, including the reception of RAR and Msg4 during the random access process, and the transmission of preamble and Msg3.

[0138] In this application, the initial BWP may be understood as a BWP that supports the UE to perform initial access, or the UE performs random access on the initial BWP.

[0139] 2. Activate BWP

[0140] After a terminal device accesses a network device, in addition to the initial BWP (i.e., BWP 0), the network device may also configure other BWPs for data transmission, such as BWP 1 and BWP 2, as needed. At the same time, the network device may activate a specific BWP from these BWPs for data transmission. This activated BWP is referred to as an active BWP. Active BWPs include an active uplink BWP (active UL BWP) and / or an active downlink BWP (active DL BWP). A UE may also perform random access on an active BWP.

[0141] 3. Duplex mode

[0142] Currently, NR systems include frequency division duplex (FDD) and time division duplex (TDD).

[0143] FDD can be understood as being able to perform downlink and uplink transmissions simultaneously, but at different frequencies. Figure 2 As shown in (a), in time slot 0, the UE can receive downlink data on the downlink (DL) BWP, and can also send uplink data on the uplink (UL) BWP of time slot 0.

[0144] TDD can be understood as not being able to perform downlink and uplink transmissions simultaneously. Figure 2 As shown in (b), the UE can only receive downlink data in time slot 0 and can only send uplink data in time slot 4. Time slot 3 is a flexible time slot, that is, it can send uplink data or receive downlink data, but not send uplink data and receive downlink data at the same time.

[0145] Compared with FDD, TDD occupies less frequency domain resources. However, since the transmission direction in a time slot in TDD is fixed, it will increase the uplink transmission delay, for example Figure 2 The time slot 0 shown in (b) can only be used for downlink transmission, not uplink transmission; for example, Figure 2 Only uplink transmission can be performed on time slot 4 shown in (b), and downlink transmission cannot be performed. In order to solve the delay problem of TDD, complementary time division duplex (C-TDD) is proposed. C-TDD can also be called full duplex. Figure 2 As shown in (c), in time slot 0, a frequency domain resource is allocated within the BWP for uplink transmission. This allows uplink data to be sent or received, or even simultaneously, in time slot 0, reducing uplink transmission latency. Furthermore, compared to TDD, full-duplex provides more uplink resources, which can also improve uplink coverage.

[0146] 3. Subband non-overlapping full duplex (SBFD)

[0147] The SBFD solution configures a section of resources for uplink transmission on downlink symbols (abbreviated as D symbols) and / or flexible symbols (abbreviated as F symbols) in the TDD system.

[0148] In SBFD, a carrier or a BWP is divided into multiple subbands, and different subbands can have different transmission directions. For example, a BWP may include subband #1 and subband #2. Subband #1 and subband #2 have different transmission directions. For example, subband #1 can be used by terminal devices to send uplink signals to network devices, while subband #2 can be used by network devices to send downlink signals to terminal devices.

[0149] It can be understood that subband #1 and subband #2 refer to two types of subbands with different transmission directions, and do not mean that a BWP contains only two subbands. For example, a BWP includes subband #1 and subband #2, where the transmission directions of subband #1 and subband #2 are different. Alternatively, a carrier includes subband #1, subband #2, and subband #3, where the transmission directions of subband #1 and subband #3 are the same, and the transmission directions of subband #1 and subband #2 are different. In the embodiment of the present application, the BWP used for uplink transmission is called an uplink (UP) BWP, and the BWP used for downlink transmission is called a downlink (DL) BWP; the subband used for uplink transmission is called a UL subband, and the subband used for downlink transmission is called a DL subband.

[0150] 4. Uplink symbols, downlink symbols, flexible symbols and SBFD symbols

[0151] The frequency domain resources on the uplink symbol (denoted as U symbol) can be used for uplink transmission; the frequency domain resources on the downlink symbol (denoted as D symbol) can be used for downlink transmission; the frequency domain resources on the flexible symbol (denoted as F symbol) can be used for uplink transmission or downlink transmission, and the transmission direction of the flexible symbol can be determined based on control signaling.

[0152] In this application, if the frequency domain resources on a symbol include frequency domain resources for uplink transmission (e.g., uplink subband) and frequency domain resources for downlink transmission (e.g., downlink subband), the symbol can be called an SBFD symbol. There can also be a guard band between the DL subband and the UL subband. The frequency domain resources on a symbol can be understood as the frequency domain resources on the entire BWP. The BWP can be a downlink BWP, such as an activated downlink BWP. More specifically, for example, if the frequency domain resources of the entire activated downlink BWP on a symbol are configured with a UL subband, then the frequency domain resources on the symbol include the UL subband and the DL subband, and the symbol can be an SBFD symbol.

[0153] For ease of description, uplink symbols, downlink symbols, and flexible symbols are collectively referred to as non-SBFD symbols. It can be understood that the frequency domain resources on non-SBFD symbols include frequency domain resources used for uplink transmission, or frequency domain resources used for downlink transmission. For example Figure 3 The figure shows the resource locations of one SBFD symbol and two non-SBFD symbols (non-SBFD symbol #1 and non-SBFD symbol #2) in the time and frequency domains. The frequency domain resources of the SBFD symbol include the UL subband and the DL subband. Non-SBFD symbol #1 may be a downlink symbol or a flexible symbol, while non-SBFD symbol #2 may be an uplink symbol or a flexible symbol.

[0154] The relative positions of the UL subband and the DL subband on the above SBFD symbol are only examples and are not limited in this application. For example, the UL subband may also be located at an edge position.

[0155] 5. Full-duplex time domain resources and non-full-duplex time domain resources

[0156] In an embodiment of the present application, uplink transmission or downlink transmission can be performed on a frequency domain resource within a BWP. The frequency domain resource can be configured by the base station. If uplink transmission is performed on the frequency domain resource (which can be understood as a UL subband in this case), downlink transmission (which can be understood as a DL subband) can also be performed on part or all of the frequency domain resources within the BWP (which can be understood as a DL BWP) other than the frequency domain resource. If downlink transmission is performed on the frequency domain resource (which can be understood as a DL subband), uplink transmission (which can be understood as a UL subband) can also be performed on part or all of the frequency domain resources within the BWP (which can be understood as a UL BWP) other than the frequency domain resource. The time domain resource in which the frequency domain resource is located can be called a full-duplex time domain resource. For example, the full-duplex time domain resource is the above-mentioned SBFD symbol. That is, the full-duplex time domain resource can be used for both uplink and downlink transmission at the same time. For example, the base station and / or the terminal performs uplink and downlink transmission simultaneously on the full-duplex time domain resource. For example, a base station performs both uplink and downlink transmissions on full-duplex time domain resources (i.e., the base station is full-duplex), but a terminal can be half-duplex, meaning that the terminal can only perform downlink or uplink transmissions at a given moment (e.g., a symbol). In this case, on full-duplex time domain resources, the base station can perform downlink transmissions with one terminal while also performing uplink transmissions with another terminal. If the terminal is also full-duplex, then on full-duplex time domain resources, the base station can perform downlink transmissions with the terminal while also performing uplink transmissions with the terminal.

[0157] In addition, for the sake of convenience, the frequency domain resources on the BWP (which can be understood as the frequency domain resources of the entire BWP) can only be used for uplink transmission, such as uplink symbols, or can only be used for downlink transmission, such as downlink symbols, or can be used for uplink or downlink transmission, such as flexible symbols. The time domain resources where the frequency domain resources are located are called non-full-duplex time domain resources, and the non-full-duplex time domain resources can be the non-SBFD symbols mentioned above. Non-full-duplex time domain resources can only be used for uplink transmission or downlink transmission.

[0158] It should be understood that the present application does not limit the form of the time unit. The above full-duplex time domain resource is an SBFD symbol, which is only explained by taking the time unit as a symbol as an example. The time unit can also be a subframe, or a half frame, or a frame, or a mini-subframe, a time slot or a mini-time slot, or a transmission occasion (TO). The time unit can also be a time unit defined in a communication system evolved after 5G. For the sake of convenience in the following description, in the embodiment of the present application, the time unit is mainly explained as a time slot.

[0159] 6. Frequency hopping (FH)

[0160] Frequency hopping refers to the shifting of the frequency resources to which data is mapped. Generally, when frequency hopping is enabled, the location of the frequency resources to which data is mapped changes at different times. For example, the location of the frequency resources to which data is mapped varies in different time slots. Frequency hopping can achieve frequency diversity gain in the communication system, improving uplink transmission performance.

[0161] For example, in a frequency hopping mode (inter-slot frequency hopping), the time slot and the resource block (RB) satisfy the following correspondence:

[0162]

[0163] in, Indicates the time slot number; RB start Indicates the starting resource block indicated by the network device, such as RB start =0; Indicates the bandwidth size of the activated UL BWP or the initial UL BWP, that is, the number of RBs of the activated UL BWP or the initial UL BWP; RB offset Indicates the frequency domain offset indicated by the network device, which is used to determine the starting RB position of the next hop, for example, RB offset =2, In slot 0, Then in slot 1, Starting resource block RB start Refers to virtual RB (virtual resource block, VRB). slot The starting resource block in is also a VRB.

[0164] 7. Random access (RA)

[0165] The random access process may refer to the process from when the terminal device sends a random access preamble to try to access the network to when a basic signaling connection is established with the network.

[0166] It should be understood that before selecting a random access channel (RACH) occasion (RO) for sending a preamble, the terminal device needs to select an uplink carrier. For example, when a supplementary uplink (SUL) or normal uplink (NUL) is configured, the terminal device can choose whether to send the preamble on the SUL or NUL.

[0167] After selecting an uplink carrier, a terminal device (e.g., a terminal device in a radio resource control (RRC) connected state) may need to perform a bandwidth part (BWP) operation. For example, when the active uplink BWP of the terminal device is not configured with a RO, the terminal device needs to switch the active UL BWP to the initial UL BWP.

[0168] After selecting the uplink carrier or BWP operation, the terminal device can select the random access type (RA type). RA type may include, for example: four-step random access (such as Figure 4 ), two-step random access (as shown in Figure 5 ).

[0169] Furthermore, after determining the RA type, the terminal device needs to perform random access channel (RACH) resource selection: the terminal device can select the RO to send the preamble based on the selected synchronization signal block (synchronization signal and PBCH block, SSB) and the mapping relationship between SSB and RO; or, the terminal device can select the preamble to send based on the selected synchronization / broadcast signal block (synchronization signal / physical broadcast channel block, SSB) (or expressed as SS / PBCH block) and the mapping relationship between SSB and preamble.

[0170] For example, one SSB may correspond to multiple ROs, or multiple SSBs may be mapped to one RO; for another example, one SSB may correspond to one or more preambles, and different SSBs may use different preambles.

[0171] As mentioned above, RA types can include two-step random access and four-step random access. Figure 2 and Figure 3 Four-step random access and two-step random access are introduced respectively.

[0172] Figure 4 This is a schematic flow chart of a four-step random access process, which may include the following steps:

[0173] S401, a network device sends a synchronization signal, system information and / or random access configuration information to a terminal device.

[0174] Before the four-step random access, the network device sends synchronization signals and system information by broadcasting. For example, in the NR system, the network device periodically sends SSB and system information according to the configuration.

[0175] Optionally, the network device sends random access configuration information to the terminal device so that the terminal device can determine information such as the index of the random access preamble, time-frequency resources, and power configuration.

[0176] S410: The terminal device sends a random access preamble to the network device. Correspondingly, the network device receives the random access preamble from the terminal device.

[0177] The random access preamble may be carried in a random access request, and the random access request may be referred to as message 1 (message 1, Msg1).

[0178] Exemplarily, after being powered on or when needing to re-access the network, the terminal device scans the synchronization signal of the network device, synchronizes the downlink time and frequency, and receives the configuration information of the random access resource in the system information; the terminal device selects the random access resource associated with the SSB based on the configuration information and the received SSB, which includes time-frequency resources and code domain resources (random access preamble); the terminal device uses the random access resource to send a random access signal, i.e., a random access preamble (preamble or sequence). The random access signal can be carried by a physical random access channel (PRACH).

[0179] The random access preamble can be a preamble in group A or group B. The purpose of grouping the preamble is to add certain prior information so that the network device can allocate appropriate uplink resources for message 3 (Msg3) in the random access response (RAR).

[0180] For example, if the terminal device estimates that the subsequent Msg3 may be large when it connects, it can use the preamble in group B; otherwise, it can use the preamble in group A. In this way, the network device can know the group to which the preamble belongs based on the received preamble, and thus know the approximate resource requirements of Msg 3.

[0181] S420: The network device sends a RAR to the terminal device. Correspondingly, the terminal device receives the RAR from the network device.

[0182] Exemplarily, after receiving the random access preamble, the network device sends a RAR, also known as message 2 (Msg2), to the terminal device based on the random access preamble.

[0183] Msg2 may also include indication information indicating the uplink resources for sending Msg3, such as uplink grant ULgrant. That is, after receiving Msg2, the terminal device can obtain the uplink resources for sending Msg3.

[0184] S430, the terminal device sends Msg3 to the network device.

[0185] Exemplarily, after receiving Msg2, the terminal device sends Msg3 to the network device based on Msg2.

[0186] Msg3 may include layer 2 (layer 2, L2) information and / or layer 3 (layer 3, L3) information, for example, an RRC connection establishment request message.

[0187] S440: The network device sends a contention resolution message to the terminal device.

[0188] The network device sends a contention resolution message, also called message 4 (Msg4), to the terminal device.

[0189] The contention resolution message may be the contention resolution identity MAC control unit (MAC CE) of the terminal device, that is, part of the content of Msg3 or the entire content of Msg3; the contention resolution message may also be the physical downlink control channel (PDCCH) scrambled by the cell radio network temporary identifier (C-RNTI), that is, if the terminal device detects the PDCCH scrambled by the C-RNTI, it is considered that the contention resolution is successful.

[0190] It should be understood that Figure 4 The random access shown is merely an example and is not limited in this application. For a detailed description of the four-step random access, please refer to the current related art. The four-step random access is merely an example of the name of the random access procedure, and this application does not limit the specific name of the random access procedure. For example, the random access procedure may also be referred to as contention-based random access. Furthermore, in non-contention-based random access, the terminal device and the network device may only perform S410 and S420. For details, please refer to the existing related descriptions and will not be repeated here.

[0191] Figure 5 This is a schematic flow chart of a two-step random access process, which may include the following steps:

[0192] S510, the terminal device sends message A (message A, MsgA) to the network device.

[0193] The MsgA includes a preamble and a physical uplink shared channel (PUSCH).

[0194] The preamble is sent on the PRACH resource (such as the RO mentioned above); the PUSCH resource can carry L2 or L3 information, such as beam failure recovery (BFR) MAC CE or RRC connection establishment request message.

[0195] S520, the network device sends message B (message B, MsgB) to the terminal device.

[0196] Exemplarily, after receiving the MsgA message sent by the terminal device, the network device sends a MsgB message to the terminal device based on the MsgA message.

[0197] The MsgB message may include a success RAR or a fallback RAR.

[0198] When the terminal device receives the fallback RAR, the terminal device needs to fall back to the four-step random access, that is, send Msg3.

[0199] In addition to the above-mentioned fallback process from two-step random access to four-step random access, if the network device chooses to perform two-step random access when triggering random access, after the preamble of the two-step random access reaches the maximum number of transmissions, the terminal device can also fall back to four-step random access to attempt access, so as to increase the success rate of random access of the terminal device.

[0200] It should be understood that Figure 5 The random access procedure shown is merely an example and is not limited in this application. For a detailed description of two-step random access, please refer to the current related art. Two-step random access is merely an example of the name of the random access procedure, and this application does not limit the specific name of the random access procedure. For example, the random access procedure may also be referred to as contention-based random access. In non-contention-based random access, the terminal device and the network device only execute S510, and the network device sends a RAR to the terminal device. For details, please refer to the existing related description and will not be repeated here.

[0201] In the above random access process, the RAR sent by the network device to the terminal device includes a timing advance (TA) command, an uplink (UL) grant, and a temporary cell radio network temporary identifier (TC-RNTI). Figure 6 As shown in . The TAC field contains the TA value that the terminal device needs to adjust in the uplink, which is calculated by the network device; the UL grant can be used to schedule the physical uplink shared channel (PUSCH) transmission. In addition, when the PUSCH transmission fails, that is, the network device does not correctly receive the PUSCH, the network device can schedule the retransmission of the PUSCH through the TC-RNTI encrypted downlink control information (DCI) format (format) 0_0.

[0202] In contention-based random access, the PUSCH scheduled by the UL grant can be understood as Msg3, that is, the initial transmission of Msg3 scheduled by the UL grant. If the network device does not correctly receive Msg3, it can schedule Msg3 again using DCI format 0_0 scrambled by TC-RNTI. At this time, the PUSCH scheduled by the UL grant can be understood as a retransmission of Msg3. In non-contention-based random access, the PUSCH scheduled by the UL grant can be understood as normal data scheduling, but the PUSCH is scrambled with TC-RNTI. If the network device does not correctly receive the PUSCH, it can schedule the retransmission using DCI format 0_0 scrambled by TC-RNTI.

[0203] The network device can indicate the frequency domain resources for transmitting PUSCH by indicating VRB. The terminal device can determine the PRB based on the VRB indicated by the network device and the mapping relationship between VRB and PRB. For example, the mapping between VRB and PRB can adopt non-interleaved mapping. For PUSCH scheduled by UL grant in RAR or PUSCH scheduled by DCI format 0_0 with TC-RNTI scrambling:

[0204] If the activated uplink BWP includes all RBs of the initial uplink BWP, and the subcarrier spacing and cyclic prefix length of the activated uplink BWP are the same as those of the initial uplink BWP, then the VRB with index n (denoted as VRB n) is mapped to the VRB with index PRB, where Indicates the index of the starting PRB of the initial uplink BWP. The index of the PRB is the index of the PRB in the carrier, that is, PRB 0 is the first RB of the carrier. Indicates the index of the starting PRB of the activated uplink BWP (for example, the activated uplink BWP is BWP i). Similarly, the index of the PRB is the index of the PRB in the carrier. Figure 7 The position of VRB 0 shown on the left side of FIG. 1 can be understood as the reference point of VRB n at this time being the starting RB of the initial UL BWP.

[0205] Otherwise, VRB n is mapped to PRB n of active UL BWP. Figure 7 The position of VRB 0 shown on the right side of the figure can be understood as the reference point of VRB n is the starting RB of the active UL BWP.

[0206] Since the size of the frequency domain resources indicated by the TC-RNTI scrambled DCI format 0_0 is determined according to the bandwidth of the initial ULBWP (i.e., the number of RBs), for example, the bandwidth of the frequency domain resources is less than or equal to the bandwidth of the initial UL BWP, the frequency domain resources occupied by the PUSCH scheduled by the RAR UL grant or the PUSCH scheduled by the TC-RNTI scrambled DCI format 0_0 (referred to as the first PUSCH) are as follows: Figure 7 In addition, since the position of the UL subband on the SBFD time domain resource is not fixed, for example, the UL subband can be located at the edge of the BWP. Therefore, when the SBFD solution is used for uplink transmission, the first PUSCH may not be transmitted in the UL subband, that is, VRB n cannot be mapped to the UL subband, which may cause a waste of uplink resources and increase the uplink transmission delay.

[0207] For example, Figure 7 As shown in , the UL subband is located above the initial uplink BWP, and the first PUSCH needs to be transmitted on the frequency domain resources within the range #1. Therefore, the PUSCH will not be transmitted in the UL subband.

[0208] In view of this, the present application provides a communication method and a communication device to improve resource utilization and reduce the delay of uplink transmission of terminal equipment.

[0209] Figure 8 It is a schematic flow chart of a communication method 800 provided in this application, which may include the following steps.

[0210] S810: The network device sends first information to the terminal device. Correspondingly, the terminal device receives the first information from the network device.

[0211] The first information is used to schedule PUSCH transmission. Exemplarily, the first information may be a random access response (RAR) message or downlink control information (DCI). Specifically, the first information may be a UL grant in a RAR message; the format of the DCI may be 0_0, and a cyclic redundancy check (CRC) of the DCI may be scrambled using the TC-RNTI.

[0212] For example, the network device sends a RAR to the terminal device in the random access process and schedules PUSCH transmission through the UL grant. The PUSCH transmission may include the transmission of Msg3 in the random access process; or the PUSCH is a retransmitted Msg3. For example, if the Msg3 transmission fails, the network device may schedule the retransmission of Msg3 through the TC-RNTI-scrambled DCI format (format) 0_0.

[0213] Specifically, the first information may include a first index, and the first index may be used to determine the frequency domain resource for the PUSCH transmission (referred to as the first frequency domain resource). Exemplarily, the first index includes an index of a virtual frequency domain resource unit, and the index of the virtual frequency domain resource unit corresponds to the index of the physical frequency domain resource unit, that is, the terminal device can determine the physical frequency domain resource unit through the index of the virtual frequency domain resource unit, and the physical frequency domain resource unit is used for the PUSCH transmission.

[0214] For the convenience of explanation, the following takes the virtual frequency domain resource unit as VRB and the physical frequency domain resource unit as PRB as an example. The first information may be a frequency domain resource allocation field, which may indicate the starting VRB index and the number of consecutive RBs L. RBs . The first information can specifically be the frequency domain resource assignment (FDRA) field in DCI 0_0, or the frequency domain resource assignment field in the UL grant in the RAR. The first index can be understood as the index of the starting VRB, that is, the starting VRB index indicated in the frequency domain resource assignment field. The value of the starting VRB index is greater than or equal to 0 and less than the number of RBs in the initial UL BWP. The value of the starting VRB index is an integer.

[0215] It should be understood that in this application, the granularity of the frequency domain resource unit is RB, which is only an example. The granularity of the frequency domain resource unit can also be resource element (RE), resource block group (RBG) or other granularity, without limitation.

[0216] The correspondence between the first index and the PRB can be understood as the correspondence between the VRB corresponding to the first index and the PRB, that is, which PRB corresponds to the VRB with the first index. This correspondence can be determined by the reference point of the first index. The reference point of the first index can be understood as the PRB corresponding to VRB 0, or the index x of the PRB corresponding to VRB 0, where x is an integer greater than or equal to 0. Since VRB 0 corresponds to PRB x, the PRB corresponding to the VRB with the first index can be determined. Therefore, the index x of the PRB corresponding to VRB 0 is called the reference point of the first index, where x is less than the number of RBs for the activated UL BWP. For example, the VRB with the first index is VRB i, where i is an integer greater than or equal to 0. Then VRB i corresponds to PRB (i+x), that is, the index of the PRB corresponding to the VRB with the first index is the first index plus x.

[0217] For example, the reference point of the first index may be PRB 0 (the index of the PRB corresponding to VRB 0 is 0, i.e., x=0), that is, VRB 0 corresponds to PRB 0, then VRB 1 corresponds to PRB 1, VRB 2 corresponds to PRB 2, and so on. For another example, the reference point of the first index may be PRB 5 (the index of the PRB corresponding to VRB 0 is 5, i.e., x=5), that is, VRB 0 corresponds to PRB 5, then VRB 1 corresponds to PRB 6, VRB 2 corresponds to PRB 7, and so on.

[0218] It should be understood that the embodiments of the present application are described using an example where the index value starts at 0, but the present invention is not limited thereto. That is, when the index value starts at 0, the reference point of the first index is the index of the PRB corresponding to VRB 0. If the index value starts at 1, the reference point of the first index is the index of the PRB corresponding to VRB 1. The index of the PRB starts from the activated UL BWP. If the index value starts at 0, PRB 0 refers to the starting PRB of the activated UL BWP.

[0219] Furthermore, the reference point of the first index is related to the first position relationship or the second position relationship. For example, the index (eg, x) of the PRB corresponding to VRB0 is related to the first position relationship or the second position relationship.

[0220] Among them, the first position relationship is the position relationship between the second frequency domain resource and the third frequency domain resource. The second frequency domain resource is the initial BWP of the terminal device (for example, the initial uplink BWP configured for the terminal device), and the third frequency domain resource includes the frequency domain resource (for example, UL subband) used for uplink transmission on time domain resource #1, and the time domain resource #1 is the full-duplex time domain resource in the time domain resource of the PUSCH transmission. The frequency domain resource on the time domain resource can also be understood as the frequency domain resource corresponding to the time domain resource.

[0221] It should be understood that the third frequency domain resource is located within the activated DL BWP and within the activated UL BWP. For example, if the activated DL BWP includes common resource blocks (CRBs) 10 to 19 and the activated UL BWP includes CRBs 12 to 17, then the third frequency domain resource is located within CRBs 12 to 17, for example, the third frequency domain resource includes CRBs 13 to 15.

[0222] The second positional relationship is the positional relationship between the third frequency domain resource and the fourth frequency domain resource. The fourth frequency domain resource is the activated BWP of the terminal device (for example, the activated uplink BWP). It can be understood that when the activated BWP (an example of an activated BWP) is the initial BWP, the activated BWP is the initial BWP, or in other words, at this time the fourth frequency domain resource and the second frequency domain resource are both the initial BWP. At this time, it can be understood that the first positional relationship is the same as the second positional relationship, both of which are positional relationships between the second frequency domain resource and the third frequency domain resource.

[0223] Specifically, the first positional relationship can be characterized by whether there is overlap between the third frequency domain resource and the second frequency domain resource, or by the bandwidth size of the frequency domain resource overlapping between the third frequency domain resource and the second frequency domain resource. The bandwidth of the overlapping frequency domain resources can be understood as the number of overlapping RBs. The subcarrier spacing of the RB can be the subcarrier spacing of the third or second frequency domain resource.

[0224] The second positional relationship can be characterized by the size relationship between the first frequency domain interval and the bandwidth of the second frequency domain resource, wherein the first frequency domain interval is the frequency domain interval between the frequency domain starting position of the third frequency domain resource and the frequency domain starting position of the fourth frequency domain resource. The bandwidth of the second frequency domain resource can be understood as the number of RBs included in the second frequency domain resource, and the subcarrier spacing of the RB is the subcarrier spacing of the second frequency domain resource. The first frequency domain interval can also be understood as the number of RBs, and the subcarrier spacing of the RB is the subcarrier spacing of the fourth frequency domain resource or the subcarrier spacing of the third frequency domain resource. The third frequency domain resource is located in the fourth frequency domain resource, that is, the bandwidth of the frequency domain resource where the fourth frequency domain resource overlaps with the third frequency domain resource is equal to the bandwidth of the third frequency domain resource, or it can be understood that the number of PRBs where the fourth frequency domain resource overlaps with the third frequency domain resource is equal to the number of PRBs of the third frequency domain resource. The subcarrier spacing of the third frequency domain resource is the same as the subcarrier spacing of the fourth frequency domain resource.

[0225] Optionally, the method may further include: the terminal device determining a reference point of the first index based on the first position relationship or the second position relationship. The reference point of the first index is as described above. That is, the terminal device determines x based on the first position relationship or the second position relationship.

[0226] Exemplarily, the terminal device can determine whether to further determine the reference point of the first index based on the first position relationship or the second position relationship based on whether the configuration parameters of the second frequency domain resources and the fourth frequency domain resources (i.e., the initial BWP and the activated BWP) are the same, and the position relationship between the initial BWP and the activated BWP.

[0227] In a possible implementation, when the configuration parameters of the initial BWP and the activated BWP are the same, and the activated BWP includes the initial BWP, the terminal device can determine the reference point of the first index based on the first position relationship. The configuration parameters include the subcarrier spacing and the length of the cyclic prefix (CP). The activated BWP including the initial BWP can be understood as that the activated BWP and the initial BWP have an intersection (i.e., there is an overlap), and the bandwidth of the frequency domain resources of the intersection (i.e., the number of overlapping RBs) is equal to the bandwidth of the initial BWP (i.e., the number of RBs of the initial BWP), or it can be understood as that the activated UL BWP includes all RBs of the initial UL BWP. The subcarrier spacing of the RB is the subcarrier spacing in the configuration parameters.

[0228] In one example, if the third frequency domain resource does not overlap with the second frequency domain resource (which can be understood as RB non-overlapping), the reference point of the first index is located in the third frequency domain resource, illustratively, at the frequency domain starting position of the third frequency domain resource. Figure 11(d) shows a case where the UL subband (an example of a third frequency domain resource) does not overlap with the initial BWP. At this time, the reference point of the first index can be located at the frequency domain starting position of the UL subband (for example, the starting RB). The subcarrier spacing of the third frequency domain resource and the second frequency domain resource can be the same. The frequency domain starting position of the third frequency domain resource can be understood as the PRB corresponding to the frequency domain starting position of the third frequency domain resource, or can be understood as the PRB overlapping with the frequency domain starting position of the third frequency domain resource. The index of the PRB is the index of the PRB on the fourth frequency domain resource.

[0229] Based on the above scheme, when there is no overlap between the third frequency domain resources and the second frequency domain resources, by determining the reference point of the first index as the frequency domain starting position of the third frequency domain resources, the first frequency domain resources can be located within the third frequency domain resources, that is, the terminal device can use the frequency domain resources for uplink transmission on the full-duplex time domain resources to perform the PUSCH transmission, which can reduce the delay of the PUSCH transmission.

[0230] If the third frequency domain resource overlaps with the second frequency domain resource, the reference point of the first index is located in the second frequency domain resource, illustratively, at the frequency domain starting position of the second frequency domain resource (for example, the starting RB). That is, when the third frequency domain resource overlaps with the initial BWP, the terminal device can determine the reference point of the first index in an existing manner, that is, the reference point of the first index is the frequency domain starting position of the initial BWP. For example, Figure 11 (a), (b) and (c) show the situation where the UL subband (an example of the third frequency domain resource) overlaps with the initial BWP. In this case, the reference point of the first index can be the frequency domain starting position of the initial BWP (for example, the starting RB). That is, the VRB with index n (denoted as VRB n) is mapped to the VRB with index of PRB. Among them, Indicates the starting RB of the initial BWP, Indicates the starting RB for activating the BWP.

[0231] It should be understood that the reference point of the first index is located at the frequency domain starting position of the frequency domain resource (e.g., the third frequency domain resource or the second frequency domain resource) is only an example of the reference point of the first index being located in the frequency domain resource. By determining that the reference point of the first index is located at the starting position of the frequency domain resource, resource utilization can be improved. The reference point of the first index can also be located at other positions of the frequency domain resource, and this application does not limit this. The following description of the same or similar situations is omitted.

[0232] It can be understood that when the UL subband overlaps with the initial BWP, by determining the reference point of the first index as the starting RB of the initial BWP, the first frequency domain resource can be located within the UL subband, that is, the terminal device can use the frequency domain resources used for uplink transmission on the full-duplex time domain resources to perform the PUSCH transmission, thereby reducing the delay of the PUSCH transmission.

[0233] In another example, if the bandwidth of the frequency domain resource where the third frequency domain resource overlaps with the second frequency domain resource is smaller than the bandwidth of the second frequency domain resource, the reference point of the first index is located in the third frequency domain resource. Exemplarily, the reference point of the first index is the frequency domain starting position of the third frequency domain resource. It should be understood that in this case, the bandwidth of the frequency domain resource where the third frequency domain resource overlaps with the second frequency domain resource can also be 0, that is, there is no overlap between the third frequency domain resource and the second frequency domain resource. For example, Figure 11 (b), (c), and (d) show the case where the bandwidth of the frequency domain resource where the UL subband (an example of the third frequency domain resource) overlaps with the initial BWP is smaller than the bandwidth of the initial BWP, where: Figure 11 (d) shows a situation where the UL subband does not overlap with the initial BWP. In this case, the reference point of the first index may be the frequency domain starting position of the UL subband.

[0234] Based on the above scheme, when the frequency domain resources where the third frequency domain resources overlap with the second frequency domain resources are smaller than the second frequency domain resources, by determining the reference point of the first index as the frequency domain starting position of the third frequency domain resources, the terminal device can utilize the frequency domain resources for uplink transmission on the full-duplex time domain resources to perform the PUSCH transmission, thereby reducing the delay of the PUSCH transmission.

[0235] If the bandwidth of the frequency domain resource where the third frequency domain resource overlaps with the second frequency domain resource is equal to the bandwidth of the second frequency domain resource, or in other words, the third frequency domain resource includes all the second frequency domain resources, then the reference point of the first index is located in the second frequency domain resource. Exemplarily, the reference point of the first index may be the frequency domain starting position of the second frequency domain resource. For example, Figure 11 (a) shows a case where the UL subband (an example of the third frequency domain resource) includes all initial BWPs. In this case, the reference point of the first index may be the frequency domain starting position of the initial BWP.

[0236] It can be understood that when the UL sub-band includes all the initial BWPs, by determining that the reference point of the first index is located at the initial BWP, the first frequency domain resource can be within the UL sub-band, that is, the terminal device can use the frequency domain resources used for uplink transmission on the full-duplex time domain resources to perform the PUSCH transmission, thereby reducing the delay of the PUSCH transmission.

[0237] In another possible implementation, when the configuration parameters of the initial BWP and the activated BWP are different, or the frequency domain resources overlapped by the activated BWP and the initial BWP (which can be understood as the number of overlapping RBs) are less than the bandwidth of the initial BWP, the terminal device can determine the reference point of the first index based on the second positional relationship. The configuration parameters refer to the description in the first possible implementation.

[0238] In one example, if the first frequency domain interval is greater than or equal to the bandwidth of the second frequency domain resource, the reference point of the first index is located at the third frequency domain resource, illustratively, at the frequency domain starting position of the third frequency domain resource. Figure 12 (d) shows the situation where the frequency domain interval (an example of the first frequency domain interval) between the UL subband (an example of the third frequency domain resource) and the activated BWP (an example of the fourth frequency domain resource) is greater than the bandwidth of the initial BWP (an example of the second frequency domain resource). At this time, the reference point of the first index can be located at the frequency domain starting position of the UL subband.

[0239] Based on the above scheme, when the frequency domain interval between the UL subband and the activated BWP is greater than or equal to the bandwidth of the initial BWP, by determining the reference point of the first index as the frequency domain starting position of the third frequency domain resource, the terminal device can utilize the frequency domain resources for uplink transmission on the full-duplex time domain resources to perform the PUSCH transmission, thereby reducing the delay of the PUSCH transmission.

[0240] If the first frequency domain interval is smaller than the bandwidth of the second frequency domain resource, the reference point of the first index is located at the fourth frequency domain resource, illustratively, at the frequency domain starting position of the fourth frequency domain resource. Figure 12 (a), (b) and (c) show the situation where the frequency domain interval (an example of the first frequency domain interval) between the UL subband (an example of the third frequency domain resource) and the activated BWP (an example of the fourth frequency domain resource) is smaller than the bandwidth of the initial BWP (an example of the second frequency domain resource). At this time, the reference point of the first index can be located at the frequency domain starting position of the activated BWP.

[0241] It can be understood that when the first frequency domain interval is smaller than the bandwidth of the second frequency domain resource, by determining that the reference point of the first index is located at the activated BWP, the first frequency domain resource can include all or part of the third frequency domain resource, that is, the terminal device can use the frequency domain resources used for uplink transmission on the full-duplex time domain resources to perform the PUSCH transmission, thereby reducing the delay of the PUSCH transmission.

[0242] In another example, if the first frequency domain interval is greater than 0, or in other words, if there is a frequency domain interval between the third frequency domain resource and the fourth frequency domain resource, the reference point of the first index is located in the third frequency domain resource; otherwise, the reference point of the first index is located in the fourth frequency domain resource. Figure 12 (b), (c) and (d) show the case where the frequency domain interval between the UL subband and the activated BWP (an example of the first frequency domain interval) is greater than 0. In this case, the reference point of the first index can be the frequency domain starting position of the UL subband; otherwise, the position relationship between the UL subband and the activated BWP is as follows: Figure 12 As shown in (a), the reference point of the first index can be the frequency domain starting position of the activated BWP.

[0243] Based on the above scheme, when there is a frequency domain gap between the UL subband and the activated BWP, by determining the reference point of the first index as the frequency domain starting position of the third frequency domain resource, the terminal device can utilize the frequency domain resources for uplink transmission on the full-duplex time domain resources to perform the PUSCH transmission, thereby reducing the delay of the PUSCH transmission.

[0244] In another possible implementation, the time domain resource for the PUSCH transmission includes a full-duplex time domain resource. In this case, the reference point of the first index is determined to be located on the third frequency domain resource on the full-duplex time domain resource. That is, in this case, the reference point of the first index is determined to be located on the frequency domain resource used for uplink transmission on the full-duplex time domain resource. Figure 11 or Figure 12 In the example, the reference point of the first index is located in the UL sub-band, such as the reference point of the first index is the starting position of the UL sub-band in the frequency domain.

[0245] Based on the above scheme, when the time domain resources for the PUSCH transmission include full-duplex time domain resources, by determining the starting frequency domain position of the frequency domain resources used for uplink transmission on the full-duplex time domain resources as the reference point of the first index, the first frequency domain resources can be located within the frequency domain resources used for uplink transmission, thereby reducing the delay of the PUSCH transmission.

[0246] In addition, if there is frequency hopping in the PUSCH transmission on the non-full-duplex time domain resources and the full-duplex time domain resources, that is, there is a frequency domain interval (recorded as the second frequency domain interval) between the frequency domain starting position of the first frequency domain resource on the non-full-duplex time domain resources and the frequency domain starting position on the full-duplex time domain resources, then on the full-duplex time domain resources, the reference point of the first index can be the position of the reference point of the first index determined above. At this time, the frequency domain starting position of the first frequency domain resource on the full-duplex time domain resource can be determined based on the reference point of the first index and the first index, or based on the reference point of the first index, the first index and the second frequency domain interval. The second frequency domain interval can be understood as the RB in formula (1) offset , or, the second frequency domain interval is used to indicate the frequency domain position of PUSCH frequency hopping (ie, the frequency domain position of the second hop); the first index can be understood as the starting VRB in formula (1), i.e., RB start If the time slot number of the full-duplex time domain resource is satisfy The frequency domain starting position of the first frequency domain resource on the full-duplex time domain resource is determined according to the reference point of the first index and the first index; if the time slot number of the time slot where the full-duplex time domain resource is located is satisfy The frequency domain starting position of the first frequency domain resource on the full-duplex time domain resource is determined based on the reference point of the first index, the first index and the second frequency domain interval. Then based on And the reference point of the first index determines the frequency domain starting position of the first frequency domain resource. It can be understood as time slot The index of the starting VRB on .

[0247] The frequency domain position of the reference point of the first index of the PUSCH transmission on the full-duplex time domain resource is determined by the above possible implementation manner. Optionally, the PUSCH transmission may also include non-full-duplex time domain resources (such as Figure 13 UL slot shown in ). This application does not limit the position of the reference point of the first index on the non-full-duplex time domain resource.

[0248] Exemplarily, on the non-full-duplex time domain resource, the position of the reference point of the first index may be the same as the position of the reference point of the first index on the full-duplex time domain resource.

[0249] For example, Figure 13 As shown in (c), the frequency domain position of the RB where VRB 0 is located on the UL slot (an example of non-full-duplex time domain resources) (denoted as RB#0) and the RB where VRB 0 is located on the SBFD slot (an example of full-duplex time domain resources) (denoted as RB#1) are the same.

[0250] For another example, if PUSCH transmission has frequency hopping on non-full-duplex time domain resources and full-duplex time domain resources, then on the non-full-duplex time domain resources, the position of the reference point of the first index may be the position of the reference point of the first index determined in any of the above examples. Figure 13 As shown in (d), the frequency domain interval between the RB where VRB 0 is located on the UL slot and the RB where VRB 0 is located on the SBFD slot is the second frequency domain interval (denoted as interval #1).

[0251] Optionally, on the non-full-duplex time domain resource, the position of the reference point of the first index is different from the position of the reference point of the first index on the full-duplex time domain resource. In this case, the reference point of the first index on the non-full-duplex time domain resource can refer to the existing relevant description. For example, when the configuration parameters of the initial BWP and the activated BWP are the same, and the activated BWP includes the initial BWP, the reference point of the first index can be the frequency domain starting position of the initial BWP; when the configuration parameters of the initial BWP and the activated BWP are different, or the bandwidth of the overlapping part of the activated BWP and the initial BWP (which can also be understood as the number of overlapping RBs) is less than the bandwidth of the initial BWP (which can be understood as the number of RBs of the initial BWP), the reference point of the first index can be the frequency domain starting position of the activated BWP.

[0252] For example, Figure 13 As shown in (a), the reference point of the first index on the UL slot is the starting PRB of the activated BWP, that is, VRB 0 corresponds to the starting PRB of the activated BWP, and the reference point of the first index on the SBFD slot is the starting PRB of the UL subband, that is, VRB0 corresponds to the starting PRB of the UL subband.

[0253] For example, Figure 13 As shown in (b), the PUSCH transmission has frequency hopping on the non-full-duplex time domain resources and the full-duplex time domain resources, then VRB 0 on the UL slot corresponds to the starting RB of the activated BWP, and on the SBFD slot, VRB 0 corresponds to the starting RB of the UL subband. When the first index is 0, the first frequency domain resource on the SBFD slot is shifted up to the second frequency domain interval based on the starting RB of the UL subband.

[0254] In the embodiment of the present application, there is no limitation on the manner in which the terminal device determines each frequency domain resource (for example, at least one of the second frequency domain resources to the fourth frequency domain resources).

[0255] Exemplarily, the frequency domain resource may be predefined.

[0256] Alternatively, the frequency domain resource may be determined by the network device and configured to the terminal device by the network device.

[0257] For example, the network device configures the initial BWP and / or activates the BWP for the terminal device through high-layer signaling and / or physical layer signaling. For example, the network device configures the initial BWP and / or activates the BWP for the terminal device through radio resource control (RRC) signaling and / or media access control (MAC) control element (CE) signaling.

[0258] For another example, the network device configures the terminal device to activate the BWP through high-layer signaling (such as RRC message and / or MAC CE), and further, the network device indicates the third frequency domain resources to the terminal device through physical layer signaling (such as DCI). The embodiment of the present application does not limit how the DCI indicates the third frequency domain resources. For example, the DCI includes an RBG bit map, and the RBG bit map is used to indicate the third frequency domain resources allocated to the terminal device. For another example, the DCI is used to indicate the starting VRB of the third frequency domain resources on the activated BWP and the number of consecutive RB resource blocks (RB).

[0259] Exemplarily, the subcarrier spacing of the third frequency domain resources may be the same as the subcarrier spacing of the fourth frequency domain resources.

[0260] S820. The terminal device determines a first frequency domain resource based on the first index and a reference point of the first index.

[0261] Exemplarily, after determining the reference point of the first index, that is, after determining the frequency domain position of the reference point of the first index, the terminal device can determine the position of the frequency domain resource corresponding to the first index based on the frequency domain position of the reference point of the first index, thereby determining the first frequency domain resource.

[0262] For example, if the first index indicated by the network device includes VRB 0 to VRB n, where n is a positive integer, then the reference point at the first index is located at the frequency domain starting position of the initial BWP (e.g. Figure 7 In the case of PRB 7 shown in , the first frequency domain resource may include PRB 7 to PRB (7+n); when the reference point of the first index is located at the frequency domain starting position of the UL subband (such as Figure 7 In the case of PRB 16) shown in , the first frequency domain resources may include PRB 16 to PRB (16+n).

[0263] For another example, if the first index indicated by the network device includes VRB n to VRB (n + m), where m and n are positive integers, then the reference point at the first index is located at the frequency domain starting position of the initial BWP (e.g. Figure 7 In the case of PRB 7 shown in , the first frequency domain resource may include PRB (7+n) to PRB (7+n+m); the reference point of the first index is located at the frequency domain starting position of the UL subband (such as Figure 7 In the case of PRB 16) shown in , the first frequency domain resources may include PRB (16+n) to PRB (16+n+m).

[0264] Optionally, the first index can also indicate the frequency domain starting position of the first frequency domain resource, that is, the index of the starting VRB. Furthermore, the first information can also indicate the number of continuous frequency domain resource units occupied by the first frequency domain resource, which can be understood as the number of continuous VRBs. In this case, the terminal device determines the position of the frequency domain resource corresponding to the first index through the reference point of the first index, and determines the first frequency domain resource based on the position of the frequency domain resource and the number of continuous frequency domain resource units. It can be understood that the terminal device determines the first frequency domain resource based on the reference point of the first index, the first index and the number of continuous RBs.

[0265] For example, if the first index indicates VRB 0, and the network device indicates that the number of continuous frequency domain resource units occupied by the first frequency domain resource is k, where k is a positive integer, then the reference point at the first index is located at the frequency domain starting position of the initial BWP (e.g. Figure 7 In the case of PRB 7 shown in , the frequency domain starting position of the first frequency domain resource is PRB 7, and the first frequency domain resource includes PRB 7 to PRB (7+k-1).

[0266] S830: The terminal device performs the PUSCH transmission on the first frequency domain resource.

[0267] Exemplarily, the PUSCH transmission may include the transmission of at least two PUSCHs, wherein the at least two PUSCHs include a first PUSCH and a second PUSCH, the time domain resources of the first PUSCH include at least full-duplex time domain resources, and the time domain resources of the second PUSCH are non-full-duplex time domain resources. It can be seen from the above content that the frequency domain starting positions of the first PUSCH and the second PUSCH may be the same or different.

[0268] Among them, the time domain resources of the first PUSCH at least include full-duplex time domain resources, which can be understood as the time domain resources of the first PUSCH are full-duplex time domain resources, or the time domain resources of the first PUSCH include full-duplex time domain resources and non-full-duplex time domain resources. For example, the time domain resources of the first PUSCH are one time slot, and the one time domain may include SBFD symbols and non-SBFD symbols (such as uplink symbols). The first PUSCH and the second PUSCH can be understood as repetitions of PUSCH.

[0269] Optionally, the PUSCH transmission may also include the transmission of one PUSCH.

[0270] Figure 9 This is a schematic flow chart of a communication method 900 provided in this application. The method may include the following steps.

[0271] S910: The network device sends first information to the terminal device. Correspondingly, the terminal device receives the first information from the network device.

[0272] The first information is used to schedule PUSCH transmission. For details of the first information, please refer to the description of S810.

[0273] Exemplarily, the first information may include a first index, which may be used to determine the frequency domain resource for performing the PUSCH transmission (denoted as the first frequency domain resource). For example, the frequency domain resource corresponding to the first index is the first frequency domain resource. For another example, the first frequency domain resource is determined by the first index, the number of consecutive frequency domain resource units, and the reference point of the first index.

[0274] Specifically, the first index includes the index of the virtual frequency domain resource unit, for example, the index of the starting virtual frequency domain resource unit. For example, if the virtual frequency domain resource unit is a VRB, the first index is the index of the starting VRB. In this case, the first index is the starting VRB index indicated in the frequency domain resource allocation domain. The value of the index of the starting VRB is greater than or equal to 0 and is less than the number of RBs of the initial ULBWP. The value of the index of the starting VRB is an integer. The number of consecutive frequency domain resource units can be understood as the number of consecutive RBs L indicated by the FDRA domain. RBs .

[0275] There is a correspondence between the virtual frequency domain resource unit and the physical frequency domain resource unit, or there is a correspondence between the index of the virtual frequency domain resource unit and the index of the physical frequency domain resource unit. That is, the terminal device can determine the index of the physical frequency domain resource unit through the index of the virtual frequency domain resource unit, or determine the physical frequency domain resource unit based on the virtual frequency domain resource unit. The physical frequency domain resource unit is used for the PUSCH transmission. For the convenience of explanation, the following description takes the virtual frequency domain resource unit as VRB and the physical frequency domain resource unit as PRB as an example.

[0276] For the correspondence between the first index and the PRB, reference may be made to the description in S810.

[0277] It should be understood that the embodiments of the present application are described using an example where the index value starts at 0, but the present invention is not limited thereto. That is, when the index value starts at 0, the reference point of the first index is the index of the PRB corresponding to VRB 0. If the index value starts at 1, the reference point of the first index is the index of the PRB corresponding to VRB 1. The index of the PRB starts from the activated UL BWP. If the index value starts at 0, PRB 0 refers to the starting PRB of the activated UL BWP.

[0278] Furthermore, the PRB corresponding to the first index can be determined by the PRB corresponding to the reference point of the first index. The PRB corresponding to the reference point of the first index is located in the third frequency domain resource, for example, the reference point of the first index is the frequency domain starting position of the third frequency domain resource. The third frequency domain resource includes the frequency domain resource for uplink transmission on the full-duplex time domain resource. It should be understood that the third frequency domain resource (i.e., UL subband) is located within the activated DL BWP, and within the activated UL BWP. For example, the activated DL BWP includes CRB 10 to CRB 19, and the activated UL BWP includes CRB 12 to CRB 17, then the third frequency domain resource is located within CRB 12 to CRB 17, for example, the third frequency domain resource includes CRB 13 to CRB 15. The subcarrier spacing of the third frequency domain resource is the same as the subcarrier spacing of the activated UL BWP.

[0279] For example, if the first index includes VRB 0 to VRB n, where n is a positive integer, then the reference point at the first index is located at the frequency domain starting position of the third frequency domain resource (e.g. Figure 7 In the case of RB 16) shown in , the frequency domain resources corresponding to the first index may include RB 16 to RB (16+n).

[0280] The reference point of the first index is the frequency domain starting position of the third frequency domain resource. It can be understood that the reference point of the first index is the starting PRB of the third frequency domain resource, that is, VRB 0 is mapped to the starting PRB of the third frequency domain resource, or it can be understood that the reference point of the first index is the index of the starting PRB of the third frequency domain resource. For example, if the index of the starting PRB of the third frequency domain resource is j, then VRB 0 is mapped to PRB j. j is an integer greater than or equal to 0. The value of j must be less than the number of RBs in the activated BWP. The index of the starting PRB of the third frequency domain resource is the index of the starting PRB of the third frequency domain resource within the activated BWP. For example, if j=0, the reference point of the first index can be PRB 0 (the index of the PRB corresponding to VRB 0 is 0, that is, x=0), that is, VRB 0 corresponds to PRB 0, then VRB 1 corresponds to PRB 1, VRB 2 corresponds to PRB 2, and so on. For another example, j=5, then the reference point of the first index may be PRB 5 (the index of the PRB corresponding to VRB 0 is 5, ie x=5), that is, VRB 0 corresponds to PRB 5, then VRB 1 corresponds to PRB 6, VRB 2 corresponds to PRB 7, and so on.

[0281] Exemplarily, in the cases shown in the following examples, the frequency domain resource corresponding to the reference point of the first index is located in the third frequency domain resource, for example, the frequency domain starting position of the third frequency domain resource.

[0282] Example #1, the configuration parameters of the initial BWP (an example of the second frequency domain resource) and the activated BWP (an example of the fourth frequency domain resource) are the same, and the activated BWP includes the initial BWP; the third frequency domain resource does not overlap with the second frequency domain resource, that is, the frequency domain resource used for uplink transmission on the full-duplex time domain resource of PUSCH transmission does not overlap with the initial BWP. For example, Figure 11 (d) shows a case where the UL subband (an example of a third frequency domain resource) does not overlap with the initial BWP. Configuration parameters include the subcarrier spacing and the cyclic prefix length. The activated BWP including the initial BWP can be understood as including all RBs in the initial UL BWP.

[0283] Example #2: The configuration parameters of the initial BWP (an example of the second frequency domain resource) and the activated BWP (an example of the fourth frequency domain resource) are the same, and the activated BWP includes the initial BWP; the bandwidth of the frequency domain resource where the third frequency domain resource overlaps with the second frequency domain resource is smaller than the bandwidth of the second frequency domain resource. Figure 11(b), (c), and (d) illustrate the case where the bandwidth of the frequency domain resource where the UL subband (an example of the third frequency domain resource) overlaps with the initial BWP is smaller than the bandwidth of the initial BWP. The bandwidth of the overlapping frequency domain resource can be understood as the number of overlapping RBs. The subcarrier spacing of the RB can be the subcarrier spacing of the third or second frequency domain resource. The bandwidth of the second frequency domain resource can be understood as the number of RBs included in the second frequency domain resource, and the subcarrier spacing of the RB is the subcarrier spacing of the second frequency domain resource.

[0284] Example #3: The configuration parameters of the initial BWP and the activated BWP are different, or the frequency domain resources overlapped by the activated BWP and the initial BWP are smaller than the bandwidth of the initial BWP; the frequency domain interval (i.e., the first frequency domain interval) between the frequency domain starting position of the third frequency domain resource and the frequency domain starting position of the fourth frequency domain resource is greater than or equal to the bandwidth of the second frequency domain resource. For example, Figure 12 (d) shows a case where the frequency domain spacing (an example of the first frequency domain spacing) between the UL subband (an example of the third frequency domain resource) and the activated BWP (an example of the fourth frequency domain resource) is greater than the bandwidth of the initial BWP (an example of the second frequency domain resource). The first frequency domain spacing can also be understood as the number of RBs, and the subcarrier spacing of the RBs is the subcarrier spacing of the fourth frequency domain resource or the subcarrier spacing of the third frequency domain resource.

[0285] Example #4: The configuration parameters of the initial BWP and the activated BWP are different, or the frequency domain resources overlapped by the activated BWP and the initial BWP are smaller than the bandwidth of the initial BWP; the first frequency domain interval is greater than 0, or in other words, if there is a frequency domain interval between the third frequency domain resource and the fourth frequency domain resource. For example, Figure 12 (b), (c) and (d) show the case where the frequency domain interval (an example of the first frequency domain interval) between the UL subband and the activated BWP is greater than 0.

[0286] Optionally, in this example, the first frequency domain interval may also be 0, or in other words, if the frequency domain starting position of the third frequency domain resource is the frequency domain starting position of the fourth frequency domain resource. Figure 12 The situation shown in (a).

[0287] It can be understood that the first frequency domain resources determined according to Examples #1 to #4 are part or all of the frequency domain resources in the frequency domain resources for uplink transmission (i.e., UL subband) on the full-duplex time domain resources. Optionally, the terminal device determines the frequency domain resources on the non-full-duplex time domain resources for PUSCH transmission in the manner shown in Examples #1 to #4.

[0288] If the PUSCH is on a non-full-duplex time domain resource, the terminal device calculates the number of consecutive RBs based on the first index L. RBThe first frequency domain resource is determined by using the reference point of the first index. For a specific determination method, reference may be made to the description in S810.

[0289] If PUSCH transmission frequency hopping occurs between non-full-duplex time domain resources and full-duplex time domain resources, that is, there is a frequency domain interval (denoted as the second frequency domain interval) between the frequency domain starting position of the first frequency domain resource on the non-full-duplex time domain resource and the frequency domain starting position on the full-duplex time domain resource, then on the full-duplex time domain resource, the reference point of the first index may be the position of the reference point of the first index determined above. For details, refer to the description in S810.

[0290] It should be understood that the third frequency domain resources, the second frequency domain resources, and the fourth frequency domain resources can refer to the relevant description in S810.

[0291] S920: The terminal device performs the PUSCH transmission on the first frequency domain resource.

[0292] Exemplarily, the PUSCH transmission may include the transmission of at least two PUSCHs, wherein the at least two PUSCHs include a first PUSCH and a second PUSCH, the time domain resources of the first PUSCH include at least full-duplex time domain resources, and the time domain resources of the second PUSCH are non-full-duplex time domain resources. As can be seen from the above content, the frequency domain starting positions of the first PUSCH and the second PUSCH may be the same or different. For details of this step, reference may be made to the description of S830. The first PUSCH and the second PUSCH may be understood as repetitions of the PUSCH.

[0293] Exemplarily, the PUSCH transmission may also include only one PUSCH transmission, that is, there is no repetition.

[0294] Figure 10 This is a schematic flow chart of a communication method 1000 provided in this application. The method may include the following steps.

[0295] S1010: The network device sends first information to the terminal device. Correspondingly, the terminal device receives the first information from the network device.

[0296] The first information is used to schedule PUSCH transmission. The first information may refer to the description in S810.

[0297] Specifically, the first information may include a first index, which can be used to determine the frequency domain resource for the PUSCH transmission (referred to as the first frequency domain resource). Exemplarily, the first index includes an index of a virtual frequency domain resource unit, and the index of the virtual frequency domain resource unit corresponds to the index of the physical frequency domain resource unit. The terminal device can determine the index of the physical frequency domain resource unit based on the index of the virtual frequency domain resource unit, and the physical frequency domain resource unit is used for the PUSCH transmission. The first index can refer to the description in S810.

[0298] The reference point of the first index is located in the second frequency domain resource or the fourth frequency domain resource, for example, the frequency domain starting position of the second frequency domain resource or the fourth frequency domain resource. The second frequency domain resource is an initial BWP (for example, an initial uplink BWP); the fourth frequency domain resource is an activated BWP (for example, an activated uplink BWP). The second frequency domain resource and the frequency domain starting position of the second frequency domain resource can refer to the description in S810. The fourth frequency domain resource and the frequency domain starting position of the fourth frequency domain resource can also refer to the description in S810.

[0299] Exemplarily, when the configuration parameters of the second frequency domain resource and the fourth frequency domain resource are the same, and the fourth frequency domain resource includes the second frequency domain resource, the reference point of the first index is the frequency domain starting position of the second frequency domain resource; when the configuration parameters of the second frequency domain resource and the fourth frequency domain resource are different, or when the bandwidth (number of overlapping RBs) of the frequency domain resource overlapping with the second frequency domain resource is smaller than that of the second frequency domain resource, the reference point of the first index is the starting position of the fourth frequency domain resource.

[0300] The position of the frequency domain resource corresponding to the first index can be determined by determining the position (frequency domain position) of the reference point of the first index. For example, if the first index includes VRB 0 to VRB n, where n is a positive integer, then the reference point of the first index is located at the frequency domain starting position of the initial BWP (e.g. Figure 7 In the case of RB 7) shown in , the frequency domain resources corresponding to the first index may include RB 7 to RB (7+n).

[0301] S1020: The network device sends second information to the terminal device. Correspondingly, the terminal device receives the second information from the network device.

[0302] The second information can be used to determine the first frequency domain offset, or in other words, the second information indicates the first frequency domain offset. For example, the second information can directly indicate the value of the first frequency domain offset, or the second information can indirectly indicate the first frequency domain offset by indicating the interval between two frequency domain resources. The present application does not limit the manner in which the second information indicates the first frequency domain offset. The second information can be a RAR UL grant or a TC-RNTI-scrambled DCI 0_0. For example, if the base station configures a set of values for the first frequency domain offset, such as {A, B, C, D}, the second information is used to indicate which value in the set the first frequency domain offset is. The value of the first frequency domain offset can be greater than 0 or less than 0.

[0303] The first frequency domain offset can be used to determine the first frequency domain resource. That is, the first frequency domain resource is determined based on the first index and the first frequency domain offset. Alternatively, the starting frequency domain position of the first frequency domain resource is determined based on the first index and the first frequency domain offset. The first frequency domain resource overlaps with the third frequency domain resource, and the third frequency domain resource includes the frequency domain resource used for uplink transmission on the time domain resource of the PUSCH transmission. In other words, the first frequency domain resource determined by the first index and the first frequency domain offset overlaps with the third frequency domain resource.

[0304] Exemplarily, in the following examples, the first frequency domain resource is determined by a first index and a first frequency domain offset.

[0305] Example #1, the configuration parameters of the initial BWP (an example of the second frequency domain resource) and the activated BWP (an example of the fourth frequency domain resource) are the same, and the activated BWP includes the initial BWP; the third frequency domain resource does not overlap with the second frequency domain resource, that is, the time domain resource used for uplink transmission on the full-duplex time domain resource of PUSCH transmission does not overlap with the initial BWP. For example, Figure 11 (d) shows a situation where the UL subband (an example of the third frequency domain resource) does not overlap with the initial BWP.

[0306] Optionally, in this example, the value of the first frequency domain offset may be greater than the frequency domain interval between the frequency domain end position of the fifth frequency domain resource and the frequency domain starting position of the third frequency domain resource, or the value of the first frequency domain offset may be greater than the frequency domain interval between the frequency domain starting position of the fifth frequency domain resource and the frequency domain end position of the third frequency domain resource, wherein the fifth frequency domain resource is determined based on the first information.

[0307] Specifically, in the case where the first information includes a first index, the fifth frequency domain resource is determined according to the first index. For example, the first index includes VRB 0 to VRB n, where n is a positive integer, and the reference point of the first index is located at the frequency domain starting position of the initial BWP (e.g. Figure 7 In the case of RB 7) shown in , the fifth frequency domain resources may include RB7 to RB(7+n).

[0308] In the case where the first information includes a first index and the number of continuous frequency domain resource units, the fifth frequency domain resource can be determined according to the first index and the number of the continuous frequency domain resource units. For example, the first index indicates VRB 0, the first information indicates that the number of continuous frequency domain resource units is k, k is a positive integer, then the reference point of the first index is located at the frequency domain starting position of the initial BWP (such as Figure 7 In the case of RB 7) shown in , the fifth frequency domain resources include RB 7 to RB (7+k-1).

[0309] For example, assuming that the frequency domain starting position of the third frequency domain resource is RB 16, the value of the first frequency domain offset can be greater than |16-(7+n)|; assuming that the frequency domain ending position of the third frequency domain resource is RB 3, the value of the first frequency domain offset can be greater than |7-3|.

[0310] Example #2: The configuration parameters of the initial BWP (an example of the second frequency domain resource) and the activated BWP (an example of the fourth frequency domain resource) are the same, and the activated BWP includes the initial BWP; the bandwidth of the frequency domain resource where the third frequency domain resource overlaps with the second frequency domain resource is smaller than the bandwidth of the second frequency domain resource. Figure 11 (b), (c) and (d) show the case where the bandwidth of the frequency domain resource where the UL subband (an example of the third frequency domain resource) overlaps with the initial BWP is smaller than the bandwidth of the initial BWP.

[0311] In this example, if the bandwidth of the frequency domain resource where the third frequency domain resource overlaps with the second frequency domain resource is 0, the first frequency domain offset can refer to the description in Example #1.

[0312] If the bandwidth of the frequency domain resource where the third frequency domain resource overlaps with the second frequency domain resource is smaller than the bandwidth of the second frequency domain resource and greater than 0, in one possible implementation, the first frequency domain offset is greater than or equal to 0; in another possible implementation, the first frequency domain offset is greater than or equal to the frequency domain interval between the frequency domain starting position of the fifth frequency domain resource and the frequency domain starting position of the third frequency domain resource. The fifth frequency domain resource can refer to the description in Example #1.

[0313] Example #3: The configuration parameters of the initial BWP and the activated BWP are different, or the frequency domain resources overlapped by the activated BWP and the initial BWP are smaller than the bandwidth of the initial BWP; the frequency domain interval (i.e., the first frequency domain interval) between the frequency domain starting position of the third frequency domain resource and the frequency domain starting position of the fourth frequency domain resource is greater than or equal to the bandwidth of the second frequency domain resource. For example, Figure 12 (d) shows a situation where the frequency domain interval (an example of the first frequency domain interval) between the UL subband (an example of the third frequency domain resource) and the activated BWP (an example of the fourth frequency domain resource) is greater than the bandwidth of the initial BWP (an example of the second frequency domain resource).

[0314] Optionally, in this example, the value of the first frequency domain offset may be greater than the frequency domain interval between the frequency domain end position of the sixth frequency domain resource and the frequency domain start position of the third frequency domain resource, wherein the sixth frequency domain resource is determined based on the first information.

[0315] Specifically, when the first information includes a first index, the sixth frequency domain resource is determined according to the first index. For example, the first index includes VRB 0 to VRB n, where n is a positive integer, and the reference point of the first index is located at the frequency domain starting position of the activated BWP (e.g. Figure 7 In the case of RB 2) shown in , the fifth frequency domain resource may include RB2 to RB n.

[0316] In the case where the first information includes a first index and the number of continuous frequency domain resources, the sixth frequency domain resource can be determined according to the first index and the number of the continuous frequency domain resources. For example, the first index indicates VRB 0, the first information indicates that the number of continuous frequency domain resource units is k, k is a positive integer, then the reference point of the first index is located at the frequency domain starting position of the activated BWP (such as Figure 7 In the case of RB 2) shown in , the fifth frequency domain resources include RB 0 to RB (k-1).

[0317] Example #4: The configuration parameters of the initial BWP and the activated BWP are different, or the frequency domain resources overlapped by the activated BWP and the initial BWP are smaller than the bandwidth of the initial BWP; the first frequency domain interval is greater than 0, or in other words, if there is a frequency domain interval between the third frequency domain resource and the fourth frequency domain resource. For example, Figure 12 (b), (c) and (d) show the case where the frequency domain interval (an example of the first frequency domain interval) between the UL subband and the activated BWP is greater than 0.

[0318] In this example, if the first frequency domain interval is greater than the bandwidth of the second frequency domain resource, the first frequency domain offset can refer to the description in Example #3.

[0319] If the first frequency domain interval is greater than 0 and less than the bandwidth of the second frequency domain resource, in one possible implementation, the first frequency domain offset is greater than or equal to 0; in another possible implementation, the first frequency domain offset is greater than or equal to the frequency domain interval between the frequency domain starting position of the sixth frequency domain resource and the frequency domain starting position of the third frequency domain resource. The sixth frequency domain resource can refer to the description in Example #3.

[0320] Example #5: The configuration parameters of the initial BWP and the activated BWP are different, or the frequency domain resources overlapped by the activated BWP and the initial BWP are smaller than the bandwidth of the initial BWP; the first frequency domain interval is 0, or in other words, if the frequency domain starting position of the third frequency domain resource is the frequency domain starting position of the fourth frequency domain resource. For example, Figure 12 In this example, the first frequency domain offset may be 0.

[0321] Optionally, in the above example, the value of the first frequency domain offset may be less than or equal to the bandwidth size of the second frequency domain resource.

[0322] It can be understood that the first frequency domain resources determined according to Example #1 to Example #5 are frequency domain resources on the full-duplex time domain resources for PUSCH transmission.

[0323] Optionally, the terminal device determines the frequency domain resources on the non-full-duplex time domain resources for PUSCH transmission in the manner shown in Examples #1 to #5.

[0324] Alternatively, in addition to the above situation, the terminal device determines the first frequency domain resource based on the first index, or in other words, the terminal device determines the fifth frequency domain resource or the sixth frequency domain resource as the first frequency domain resource.

[0325] It should be understood that this application does not limit the specific manner in which the network device configures the first frequency domain offset. For example, the network device can configure the value of the frequency domain offset, i.e., the first frequency domain offset, for the terminal device based on the situations shown in Examples #1 to #5 above.

[0326] Alternatively, the network device may configure a set of frequency domain offset values, and the terminal device determines the appropriate frequency domain offset based on the situations shown in Examples #1 to #5 above, that is, the terminal device determines the first frequency domain offset; or, the network device may configure a range of frequency domain offsets, for example, the network device determines the range based on historical offsets, and the terminal device determines the appropriate frequency domain offset based on the situations shown in the above examples.

[0327] S1030: The terminal device performs the PUSCH transmission on the first frequency domain resource.

[0328] Exemplarily, the PUSCH transmission may include transmission of at least two PUSCHs, where the at least two PUSCHs include a first PUSCH and a second PUSCH, the time domain resources of the first PUSCH include at least full-duplex time domain resources, and the time domain resources of the second PUSCH are non-full-duplex time domain resources. As can be seen from the above content, the frequency domain starting positions of the first PUSCH and the second PUSCH may be the same or different. For details of this step, please refer to the description of S830.

[0329] Exemplarily, the PUSCH transmission may also include the transmission of one PUSCH.

[0330] In another embodiment of the present application, the network device may configure the positional relationship between the third frequency domain resource and the second frequency domain resource or the fourth frequency domain resource, so that the first frequency domain resource is located within the third frequency domain resource.

[0331] Exemplarily, when the configuration parameters of the initial BWP (an example of the second frequency domain resource) and the activated BWP (an example of the fourth frequency domain resource) are the same, and the activated BWP includes the initial BWP, the network device configures the third frequency domain resource to overlap with the second frequency domain resource. For example, the positional relationship between the third frequency domain resource and the second frequency domain resource configured by the network device is as follows: Figure 11 Alternatively, the network device configures the bandwidth of the frequency domain resource where the third frequency domain resource overlaps with the second frequency domain resource to be equal to the bandwidth of the initial BWP. For example, the network device configures the positional relationship between the third frequency domain resource and the second frequency domain resource as shown in FIG. Figure 11 Alternatively, when the third frequency domain resource configured by the network device does not overlap with the second frequency domain resource, the network device configures the UL slot to perform the PUSCH transmission.

[0332] When the configuration parameters of the initial BWP (an example of the second frequency domain resource) and the activated BWP (an example of the fourth frequency domain resource) are different, or the bandwidth of the frequency domain resource overlapped by the activated BWP and the initial BWP is smaller than the initial BWP, the network device configures the frequency domain interval between the third frequency domain resource and the fourth frequency domain resource to be smaller than the bandwidth of the initial BWP. For example, the positional relationship between the third frequency domain resource and the fourth frequency domain resource is as follows: Figure 12 (a), (b) and (c) are shown in FIG. That is, when the network device configures the third frequency domain resource, it must meet in, Indicates the starting RB of the third frequency domain resource.

[0333] Alternatively, the frequency domain interval between the third frequency domain resource and the fourth frequency domain resource is 0. For example, the positional relationship between the third frequency domain resource and the fourth frequency domain resource is as follows: Figure 12 As shown in (a). That is, when the network device configures the third frequency domain resource, it satisfies In addition, the bandwidth of the third frequency domain resource may be greater than or equal to the bandwidth of the second frequency domain resource. Otherwise, when the third frequency domain resource configured by the network device does not overlap with the second frequency domain resource, the network device configures the UL slot for the PUSCH transmission.
