[0042] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0043] First, the relevant technologies involved in the embodiments of this application are introduced:

[0044] (1) Uplink subband in downlink symbol / time slot

[0045] In related technologies, data can be sent and received simultaneously on different subbands within the same subframe. This technology, called X-Division Duplex (XDD), is primarily used on the base station side. However, the terminal device side maintains a state where only data can be sent or received within a subframe.

[0046] In some embodiments, as shown in FIG1 , the XDD technology configures the middle subband of the frequency domain resources corresponding to a downlink symbol / time slot as an uplink subband. When a terminal device is configured or instructed to receive data on the downlink symbol / time slot, such as receiving data carried on a physical downlink shared channel (PDSCH), the frequency domain resources occupied by the PDSCH overlap with the uplink subband in the frequency domain resources corresponding to the downlink symbol / time slot. Since the base station side is partially in the state of receiving uplink data from other terminal devices in the uplink subband, the base station side cannot send downlink data to the terminal device in the uplink subband. In other words, the base station side will only send PDSCH to the terminal device on the downlink subbands on both sides of the uplink subband.

[0047] The subband configurations in different symbols / time slots within a subframe may be consistent or different, and this embodiment of the present application does not impose any specific limitation on this.

[0048] (2) Frequency Domain Resource Indication Method

[0049] Methods for indicating frequency domain resources for PDSCH or Physical Uplink Shared Channel (PUSCH) generally include the following two methods:

[0050] Resource allocation type 0

[0051] Resource allocation is performed according to Type 0. The frequency domain resource information field, that is, the RB allocation information, includes a bitmap to indicate or allocate the resource block group (RBG) of the terminal device. An RBG is a set of continuous PRBs or a set of continuous virtual resource blocks (VRBs). The size of the RBG is determined by a high-level parameter, usually represented by P. The size of the RBG may be different in different bandwidth parts (BWPs) and in different frequency domain resource configurations.

[0052] For a including For an uplink or downlink BWP i of RBs, the total number of RBGs is N RBG The calculation formula is:

[0053]

[0054] Among them, the number of RBs contained in the first RBG (which can also be understood as the size of the first RBG) is if Then the number of RBs contained in the last RBG is if Then the number of RBs contained in the last RBG is The size of other RBGs is P.

[0055] The bitmap has a total of N RBG Each bit represents an RBG. RBGs are arranged in ascending order of frequency, and the index of BWP starts from the BWP with the lowest frequency. The order of the RBG bitmap is from RBG 0 to RBGN RBG-1, mapping from the most significant bit (MSB) to the least significant bit (LSB). The RBG allocated to the terminal device and the RBG not allocated to the terminal device are represented by different bit values ​​in the bitmap. When the bit value corresponding to a certain RBG in the bitmap is the first value, it indicates that the RBG is the RBG allocated to the terminal device. When the bit value corresponding to a certain RBG in the bitmap is the second value, it indicates that the RBG is the RBG not allocated to the terminal device. For example, if a certain RBG is allocated to the terminal device, the corresponding bit value in the bitmap is 1. If a certain RBG is not allocated to the terminal device, the corresponding bit value in the bitmap is 0.

[0056] For example, as shown in Figure 2, the network device allocates resources to RBG 0 to RBG 8 according to Type 0, and the bit map is 010001101, which means that the corresponding bits of RBG 1, RBG 5, RBG 6, and RBG 8 in the bit map are 1, and the corresponding bits of other RBGs in the bit map are 0, indicating that RBG 1, RBG 5, RBG 6, and RBG 8 are allocated to the terminal device.

[0057] Resource allocation method 1 (Type 1)

[0058] Resource allocation is performed according to Type 1. In the frequency domain resource information field, that is, the RB allocation information, a continuous VRB set is indicated or allocated to the terminal device. The mapping of VRBs and PRBs in the VRB set is interleaved or non-interleaved. The VRBs in the VRB set are located in the activated BWP.

[0059] For Type 1, the frequency domain resource information field consists of a resource indicator value (RIV), which is based on the starting VRB number RB. start and the allocated RB continuous length L RBS The specific calculation formula is as follows:

[0060] if So

[0061] if So

[0062] in,

[0063] For example, as shown in FIG3 , the network device allocates resources to RB 0 to RB 17 according to Type 1, indicating the starting number of the resource block RB start is 7, the continuous length of the resource block is L RBS If it is 7, it means that RB 7 to RB 14 are allocated to the terminal device.

[0076] FIG5 shows a flow chart of a resource indication method provided by some exemplary embodiments of the present application. This embodiment is illustrated by taking the method executed by a terminal device as an example. The method includes:

[0077] Step 502: The terminal device receives frequency domain resource indication information (which may be referred to as frequency domain resource indication or frequency domain resource allocation).

[0078] The frequency domain resource indication information is used to determine the frequency domain resource location of the physical channel. In some embodiments, the frequency domain resource indication information is carried in a first information field of the DCI, which is a frequency domain resource allocation (FDRA) field.

[0079] In some embodiments, the physical channel includes at least one of an uplink channel, a downlink channel, and a side channel, but is not limited thereto. The embodiments of the present application do not specifically limit this.

[0080] The number of bits of the frequency domain resource indication information is determined based on the first frequency domain bandwidth, and the valid bits of the frequency domain resource indication information are determined based on the second frequency domain bandwidth; wherein the first frequency domain bandwidth includes the second frequency domain bandwidth.

[0081] Valid bits refer to bits in the frequency domain resource indication information that are used to determine the frequency domain resources of the physical channel. Alternatively, valid bits refer to bits that need to be used, parsed, or processed when parsing the frequency domain resource indication information, and bits other than the valid bits need to be pruned or discarded.

[0082] The first frequency domain bandwidth refers to the bandwidth of a bandwidth part (BWP). The first frequency domain bandwidth is the bandwidth of the BWP activated by the terminal device. In some embodiments, the terminal device is configured with multiple BWPs, but only one BWP is activated at a time (i.e., the first frequency domain bandwidth). The first frequency domain bandwidth is typically represented by the number of resource blocks (RBs) in the BWP.

[0083] The second frequency domain bandwidth is a bandwidth used for a physical channel in the BWP.

[0084] In some embodiments, the second frequency domain bandwidth is a bandwidth used for a physical channel in an activated BWP.

[0085] In some subframes, all bandwidth in the BWP is used for the same physical channel, such as a downlink channel. In some subframes, the BWP is divided into multiple subbands, with different subbands used for different physical channels, such as the first subband for a downlink channel and the second subband for an uplink channel. When the physical channel configured by the network device to the terminal device is an uplink channel, the second frequency domain bandwidth is the bandwidth used for the uplink channel in the BWP. When the physical channel configured by the network device to the terminal device is a downlink channel, the second frequency domain bandwidth is the bandwidth used for the downlink channel in the BWP. When the physical channel configured by the network device to the terminal device is a sidelink channel, the second frequency domain bandwidth is the bandwidth used for the sidelink channel in the BWP.

[0086] In some embodiments, the second frequency domain bandwidth refers to the bandwidth of the physical channel indicated by the frequency domain resource indication information in the BWP.

[0087] For example, taking the physical channel as a downlink channel as an example, when both uplink transmission resources and downlink transmission resources exist in the same subframe, that is, when the subframe can simultaneously send and receive data, the second frequency domain bandwidth is the bandwidth used for downlink transmission in the BWP, and the second frequency domain bandwidth is expressed by the number of RBs contained in the bandwidth used for downlink transmission in the BWP. When all channels in the same subframe are downlink channels, the second frequency domain bandwidth is the bandwidth of the BWP, that is, the second frequency domain bandwidth is equal to the first frequency domain bandwidth.

[0088] In some embodiments, the second frequency domain bandwidth is a continuous bandwidth.

[0089] For example, taking the physical channel as a downlink channel as an example, when an uplink channel and a downlink channel exist simultaneously in the same subframe, that is, when the subframe can send and receive data at the same time, the second frequency domain bandwidth includes the continuous bandwidth used for downlink transmission in the BWP, and the second frequency domain bandwidth is usually expressed by the number of continuous RBs contained in the bandwidth used for downlink transmission in the BWP.

[0090] In some embodiments, the second frequency domain bandwidth refers to a discrete bandwidth.

[0091] For example, taking the physical channel as a downlink channel as an example, when an uplink channel and a downlink channel exist simultaneously in the same subframe, that is, when the subframe can send and receive data at the same time, the second frequency domain bandwidth includes the discrete bandwidth used for downlink transmission in the BWP, and the second frequency domain bandwidth is usually expressed by the number of discrete RBs contained in the bandwidth used for downlink transmission in the BWP.

[0092] In some embodiments, when data is received on different subbands in the same subframe, the second frequency domain bandwidth is the bandwidth of the BWP, that is, the second frequency domain bandwidth is equal to the first frequency domain bandwidth.

[0093] In summary, the technical solution provided by the embodiment of the present application is that the terminal device receives frequency domain resource indication information for determining the frequency domain resource position of the physical channel, the number of bits of the frequency domain resource indication information is determined based on the first frequency domain bandwidth, and the effective bit position of the frequency domain resource indication information is determined based on the second frequency domain bandwidth. In the resource indication method provided by the present application, on the one hand, the number of bits of the frequency domain resource indication information is still determined based on the first frequency domain bandwidth, because the frequency domain resource indication information is usually carried in the DCI. Therefore, when the frequency domain resource structure of the frequency domain resources scheduled by the DCI is different, the number of bits in the information domain of the frequency domain resource indication information in the DCI can be guaranteed to be the same; on the other hand, the effective bit position in the frequency domain resource indication information is determined based on the second frequency domain bandwidth, so that when the frequency domain resource structure includes frequency domain resources of different transmission directions, the terminal device determines the frequency domain resources configured for the physical channel based on the effective bit position, thereby avoiding the network device sending frequency domain resource indication information with different bit numbers according to different frequency domain resource structures.

[0094] FIG6 shows a flow chart of a resource indication method provided by some exemplary embodiments of the present application. This embodiment is illustrated by taking the method executed by a terminal device as an example. The method includes:

[0095] Step 602: The terminal device receives frequency domain resource indication information.

[0096] In some embodiments, the terminal device receives frequency domain resource indication information, referred to as frequency domain resource indication.

[0097] The frequency domain resource indication information is used to determine the frequency domain resource position of the physical channel.

[0098] The number of bits of the frequency domain resource indication information is determined based on the first frequency domain bandwidth, and the valid bits of the frequency domain resource indication information are determined based on the second frequency domain bandwidth; wherein the first frequency domain bandwidth includes the second frequency domain bandwidth.

[0099] The first frequency domain bandwidth refers to the bandwidth of a BWP. The first frequency domain bandwidth is the bandwidth of the BWP activated by the terminal device. In some embodiments, the terminal device is configured with multiple BWPs, but only one BWP is active at a time. The first frequency domain bandwidth is typically represented by the number of RBs in the BWP.

[0115] When the physical channel is a downlink channel, the second frequency domain bandwidth includes the following cases:

[0116] In the case where the physical channel is a downlink channel, the second frequency domain bandwidth includes the frequency domain bandwidth excluding the bandwidth occupied by uplink transmission resources.

[0117] Figure 7 shows a schematic diagram of resource distribution within a subframe. In the figure, the downlink subband refers to the bandwidth occupied by the downlink channel. When the physical channel is a downlink channel, the frequency domain resource indication information is used to determine the frequency domain resource location of the downlink channel. In Figure 7, the first frequency domain bandwidth is the bandwidth of the BWP, and the second frequency domain bandwidth includes the frequency domain bandwidth within the first frequency domain bandwidth used for downlink transmission. Since all resources in the subframe of Figure 7 are downlink channels, the second frequency domain bandwidth is equal to the first frequency domain bandwidth.

[0118] The frequency domain resource indication information is used to determine the frequency domain resource location of the downlink channel. The bandwidth of the BWP in the same subframe is represented by the number of RBs corresponding to the BWP. That is, the bandwidth of the first frequency domain bandwidth can be expressed as:

[0119] The bandwidth occupied by the uplink channel in the same subframe can be expressed as: N UL .

[0120] When all resources in the same subframe are downlink channels, the second frequency domain bandwidth is the bandwidth of the BWP, that is, the second frequency domain bandwidth is equal to the first frequency domain bandwidth, that is,

[0121] FIG8 is a schematic diagram of the frequency domain resource distribution in an exemplary subframe. In the figure, the downlink subband refers to the bandwidth occupied by the downlink transmission resource, and the uplink subband refers to the bandwidth occupied by the uplink transmission resource.

[0122] When an uplink channel and a downlink channel exist simultaneously in the same subframe, that is, when the subframe can send and receive data simultaneously, the second frequency domain bandwidth is the bandwidth used for downlink transmission in the BWP. The second frequency domain bandwidth is usually expressed by the number of RBs included in the bandwidth used for downlink transmission in the BWP:

[0124] In some embodiments, a schematic diagram of the frequency domain resource distribution in an exemplary subframe is shown in FIG9 . In the figure, the downlink subband refers to the bandwidth occupied by the downlink transmission resource, and the uplink subband refers to the bandwidth occupied by the uplink transmission resource. The bandwidth occupied by the uplink transmission resource and the bandwidth occupied by the downlink transmission resource are included in the same subframe. When the physical channel is an uplink channel, the frequency domain resource indication information is used to determine the frequency domain resource position of the uplink channel. In FIG9 , the first frequency domain bandwidth is the bandwidth of the BWP, and the second frequency domain bandwidth includes the frequency domain bandwidth in the first frequency domain bandwidth excluding the bandwidth occupied by the uplink transmission resource, that is, the frequency domain bandwidth in the first frequency domain bandwidth excluding the bandwidth occupied by the uplink transmission resource.

[0125] In some embodiments, the terminal device determines the number of RBs corresponding to the BWP through radio resource control layer parameters (Radio Resource Control, RRC).

[0126] In the case where the physical channel is a downlink channel, the second frequency domain bandwidth includes the frequency domain bandwidth excluding the bandwidth occupied by uplink transmission resources and the bandwidth occupied by the guard sideband.

[0127] In some embodiments, a schematic diagram of resource distribution in a subframe is shown in FIG10 . In the figure, a downlink subband refers to the bandwidth occupied by a downlink channel, and an uplink subband refers to the bandwidth occupied by an uplink channel. The same subframe includes bandwidths occupied by three downlink channels and two protection sidebands. When the physical channel is a downlink channel, the frequency domain resource indication information is used to determine the frequency domain resource position of the downlink channel. In FIG10 , the first frequency domain bandwidth is the bandwidth of the BWP, and the second frequency domain bandwidth includes the frequency domain bandwidth used for downlink transmission in the first frequency domain bandwidth. Therefore, the second frequency domain bandwidth is equal to the first frequency domain bandwidth minus the bandwidth occupied by the protection sideband.

[0128] The frequency domain resource indication information is used to determine the frequency domain resource location of the downlink channel. The bandwidth of the BWP in the same subframe is represented by the number of RBs corresponding to the BWP. That is, the bandwidth of the first frequency domain bandwidth can be expressed as:

[0129] The bandwidth occupied by the uplink channel in the same subframe can be expressed as: N UL .

[0130] The bandwidth occupied by the guard band in the same subframe can be expressed as: N G .

[0131] In the case that all channels in the same subframe are downlink channels, the second frequency domain bandwidth is the bandwidth of the BWP, that is, the second frequency domain bandwidth is equal to the first frequency domain bandwidth, that is,

[0132] In some embodiments, a schematic diagram of resource distribution in a subframe is shown in FIG11 . In the figure, a downlink subband refers to the bandwidth occupied by a downlink channel, and an uplink subband refers to the bandwidth occupied by an uplink channel. The same subframe includes bandwidths occupied by two downlink channels, a bandwidth occupied by one uplink channel, and two protection sidebands. When the physical channel is a downlink channel, the frequency domain resource indication information is used to determine the frequency domain resource location of the downlink channel. In FIG11 , the first frequency domain bandwidth is the bandwidth of the BWP, and the second frequency domain bandwidth includes the frequency domain bandwidth in the first frequency domain bandwidth excluding the bandwidth occupied by the uplink transmission resources and the bandwidth occupied by the protection sideband.

[0133] When an uplink channel and a downlink channel exist simultaneously in the same subframe, that is, when the subframe can send and receive data simultaneously, the second frequency domain bandwidth is the bandwidth used for downlink transmission in the BWP. The second frequency domain bandwidth is usually represented by the number of RBs included in the bandwidth used for downlink transmission in the BWP:

[0134]

[0135] In some embodiments, when the physical channel is a first sidelink channel, the second frequency domain bandwidth includes a frequency domain bandwidth other than a bandwidth occupied by the target transmission resource; or

[0136] The second frequency domain bandwidth includes the frequency domain bandwidth excluding the bandwidth occupied by the target transmission resource and the guard sideband; or,

[0137] The second frequency domain bandwidth includes the frequency domain bandwidth occupied by the first side channel;

[0138] Among them, the target transmission resources include: at least one of: a second side transmission resource, an uplink transmission resource and a downlink transmission resource; the second side transmission resource has a different transmission direction from the first side transmission resource, the first side transmission resource is the side transmission resource corresponding to the first side channel, and the first side transmission resource is used to transmit the first side channel.

[0139] For example, terminal device A and terminal device B communicate through a first sideline channel, and the bandwidth of the BWP between terminal device A and terminal device B is D, that is, the frequency domain bandwidth of the first frequency domain bandwidth is D. When the second sideline transmission resource is included in the same subframe, the frequency domain bandwidth of the second sideline transmission resource is d1, then, the frequency domain bandwidth of the second frequency domain bandwidth is: D-d1.

[0140] It can be understood that after the frequency domain resource position is determined, the transmission resource is used to transmit at least one of a downlink channel, an uplink channel, and a side channel. For example, when the frequency domain resource indication information determines that the physical channel is a downlink channel, the second frequency domain bandwidth includes the frequency domain bandwidth occupied by the downlink channel in the first frequency domain bandwidth; or, the second frequency domain bandwidth includes the frequency domain bandwidth occupied by the downlink transmission resource in the first frequency domain bandwidth; or, the second frequency domain bandwidth includes the frequency domain bandwidth used for downlink transmission in the first frequency domain bandwidth; or, the second frequency domain bandwidth includes the frequency domain bandwidth in the first frequency domain bandwidth excluding the bandwidth occupied by the uplink transmission resource; or, the second frequency domain bandwidth includes the frequency domain bandwidth in the first frequency domain bandwidth excluding the bandwidth occupied by the uplink transmission resource and the protection sideband.

[0141] For example, when the frequency domain resource indication information determines that the physical channel is the first sidelink channel, the second frequency domain bandwidth includes the frequency domain bandwidth occupied by the first sidelink channel; or, the second frequency domain bandwidth includes the frequency domain bandwidth occupied by the first sidelink transmission resource.

[0142] In some embodiments, the effective bit is determined in any of the following ways:

[0143] The valid bits are N1 low-order bits in the frequency domain resource indication information, where N1 is determined based on the second frequency domain bandwidth.

[0144] The effective bits are N2 high-order bits in the frequency domain resource indication information, where N2 is determined based on the second frequency domain bandwidth, and N1 and N2 are positive integers.

[0145] In some embodiments, as shown in FIG12 , a bit map of the first information field includes 10 bits, with the left side being the low-order bits and the right side being the high-order bits. When the valid bits are the N1 low-order bits in the frequency domain resource indication information, the valid bits are the lowest N1 bits counted from left to right in the bit map of the first information field. When the valid bits are the N2 high-order bits in the frequency domain resource indication information, the valid bits are the highest N2 bits counted from right to left in the bit map of the first information field.

[0146] For example, when N1 is 4, the lowest 4 bits counted from left to right in the bitmap of the first information field are taken as valid bits.

[0147] In some embodiments, the values ​​of the bits other than the valid bits in the frequency domain resource indication information are fixed values ​​or default values.

[0148] In some embodiments, the fixed value is set to 0 or 1, but is not limited thereto, and the embodiments of the present application do not make specific limitations on this.

[0149] For example, taking the fixed value as 0, the number of bits of the frequency domain resource indication information is M, the number of valid bits in the frequency domain resource indication information is m, and the Mm bits in the frequency domain resource indication information are set to 0.

[0150] In some embodiments, the size of a resource block group (RBG) within the second frequency domain bandwidth is determined based on the second frequency domain bandwidth; or,

[0151] The size of the RBG within the second frequency domain bandwidth is determined based on the first frequency domain bandwidth.

[0152] RBG refers to a set of RBs.

[0153] For example, when an uplink channel and a downlink channel exist simultaneously in the same subframe, the size of the RBG within the second frequency domain bandwidth is determined based on the second frequency domain bandwidth.

[0154] In the case that all channels in the same subframe are downlink channels, the size of the RBG in the second frequency domain bandwidth is determined based on the first frequency domain bandwidth.

[0155] In some embodiments, the frequency domain resource indication information is carried in the first information field of the downlink control information.

[0156] In some embodiments, the frequency domain resource indication information is used to determine the frequency domain resource position of the downlink channel, wherein the number of bits of the frequency domain resource indication information is determined based on the first frequency domain bandwidth and the frequency domain resource indication method.

[0157] For example, when the frequency domain resource indication mode is resource allocation mode 0 (Type 0), the number of bits of the frequency domain resource indication information is: N RBG , where N RBG Indicates BWP The number of RBGs composed of RBs.

[0158] When the frequency domain resource indication mode is resource allocation mode 1 (Type 1), the number of bits of the frequency domain resource indication information is:

[0159] In some embodiments, when the frequency domain resource indication mode is resource allocation mode 1 and resource mapping adopts the "dynamic switching" mode, the number of bits of the frequency domain resource indication information is:

[0160] The "dynamic switching" mode means that the first bit value in the DCI is used to indicate resource allocation mode 1 or resource allocation mode 0. For example, when the first bit value is 1, it indicates resource allocation mode 1, and when the first bit value is 0, it indicates resource allocation mode 0. The dynamic switching of the resource allocation mode is achieved by switching the first bit value in the DCI.

[0161] In some embodiments, the frequency domain resource indication information is used to determine the frequency domain resource position of the downlink channel, wherein the effective number of bits of the frequency domain resource indication information is determined based on the second frequency domain bandwidth and the frequency domain resource indication method.

[0162] For example, when the frequency domain resource indication mode is resource allocation mode 0 (Type 0), the effective number of bits of the frequency domain resource indication information is: N′ RBG , where N′ RBG express The number of RBGs composed of RBs.

[0163] When the frequency domain resource indication mode is resource allocation mode 1, the effective number of bits of the frequency domain resource indication information is:

[0164] In some embodiments, when the frequency domain resource indication mode is resource allocation mode 1 and resource mapping adopts the "dynamic switching" mode, the effective number of bits of the frequency domain resource indication information is:

[0165] In some embodiments, the size of the RBG within the second frequency domain bandwidth is determined based on the second frequency domain bandwidth; or, the size of the RBG within the second frequency domain bandwidth is determined based on the first frequency domain bandwidth.

[0166] The size of the RBG within the second frequency domain bandwidth is determined based on the second frequency domain bandwidth, so that the scheduling granularity of the network device for non-overlapping subband full-duplex (SBFD) terminal devices is consistent with the scheduling granularity of non-SBFD terminal devices, thereby avoiding resource fragmentation.

[0167] In some embodiments, in repeated transmission, the second frequency domain bandwidth is determined based on the bandwidth of the physical channel in the first transmission of the repeated transmission or the last transmission of the repeated transmission. In other words, in repeated transmission, the second frequency domain bandwidth is determined based on the bandwidth of the physical channel corresponding to the transmission direction in the first transmission of the repeated transmission or the last transmission of the repeated transmission.

[0168] Exemplarily, when the physical channel is a downlink channel, in at least two repeated transmissions, the second frequency domain bandwidth includes the frequency domain bandwidth occupied by the downlink channel in the first transmission of the repeated transmission; or, the second frequency domain bandwidth includes the frequency domain bandwidth occupied by the downlink channel in the last transmission of the repeated transmission.

[0169] Exemplarily, when the physical channel is an uplink channel, in at least two repeated transmissions, the second frequency domain bandwidth includes the frequency domain bandwidth occupied by the uplink channel in the first transmission of the repeated transmission; or, the second frequency domain bandwidth includes the frequency domain bandwidth occupied by the uplink channel in the last transmission of the repeated transmission.

[0170] In at least two repeated transmissions, the bandwidth of the physical channel corresponding to the transmission direction in the first transmission or the last transmission in the repeated transmission is determined as the second frequency domain bandwidth, supporting multiple repeated transmissions to use the same frequency domain resources for data transmission, reducing the complexity of data transmission, and improving the simplicity of data transmission.

[0171] Step 604: Determine the frequency domain resources of the physical channel based on the frequency domain resource indication information.

[0172] In some embodiments, the terminal device determines the frequency domain resources of the physical channel based on the valid bits in the frequency domain resource indication information.

[0173] In some embodiments, the terminal device determines the frequency domain resources of the uplink channel based on the valid bits in the frequency domain resource indication information.

[0174] For example, the frequency domain resource indication information is used to determine the frequency domain resource position of the uplink channel. The terminal device determines that the number of bits of the frequency domain resource indication information is J based on the first frequency domain bandwidth. The terminal device determines that the valid bits of the frequency domain resource indication information used to indicate the frequency domain resource position of the uplink channel are K based on the second frequency domain bandwidth. The JK bits other than the valid bits of the frequency domain resource indication information are set to 0 or 1. Then, the terminal device determines the frequency domain resources of the uplink channel based on the K valid bits in the frequency domain resource indication information.

[0175] In some embodiments, the terminal device determines the frequency domain resources of the downlink channel based on the valid bits in the frequency domain resource indication information.

[0176] For example, the frequency domain resource indication information is used to determine the frequency domain resource position of the downlink channel. The terminal device determines that the number of bits of the frequency domain resource indication information is J based on the first frequency domain bandwidth. The terminal device determines that the valid bits of the frequency domain resource indication information used to indicate the frequency domain resource position of the downlink channel are K based on the second frequency domain bandwidth. The JK bits other than the valid bits of the frequency domain resource indication information are set to 0 or 1. Then, the terminal device determines the frequency domain resources of the downlink channel based on the K valid bits in the frequency domain resource indication information.

[0177] In some embodiments, the terminal device determines the frequency domain resources of the sidelink channel based on valid bits in the frequency domain resource indication information.

[0178] For example, the frequency domain resource indication information is used to determine the frequency domain resource position of the side channel between the terminal devices. The terminal device determines that the number of bits of the frequency domain resource indication information is J based on the first frequency domain bandwidth. The terminal device determines that the valid bits of the frequency domain resource indication information used to indicate the frequency domain resource position of the side channel are K based on the second frequency domain bandwidth. The JK bits other than the valid bits of the frequency domain resource indication information are set to 0 or 1. Then, the first terminal device determines the frequency domain resources of the side channel between the first terminal device and the second terminal device based on the K valid bits in the frequency domain resource indication information.

[0179] In summary, the technical solution provided by the embodiment of the present application is that the terminal device receives frequency domain resource indication information for determining the frequency domain resource position of the physical channel, the number of bits of the frequency domain resource indication information is determined based on the first frequency domain bandwidth, and the effective bit position of the frequency domain resource indication information is determined based on the second frequency domain bandwidth. In the resource indication method provided by the present application, on the one hand, the number of bits of the frequency domain resource indication information is still determined based on the first frequency domain bandwidth, because the frequency domain resource indication information is usually carried in the DCI. Therefore, when the frequency domain resource structure of the frequency domain resources scheduled by the DCI is different, the number of bits in the information domain of the frequency domain resource indication information in the DCI can be guaranteed to be the same; on the other hand, the effective bit position in the frequency domain resource indication information is determined based on the second frequency domain bandwidth, so that when the frequency domain resource structure includes frequency domain resources of different transmission directions, the terminal device determines the frequency domain resources configured for the physical channel based on the effective bit position, thereby avoiding the network device sending frequency domain resource indication information with different bit numbers according to different frequency domain resource structures.

[0180] Furthermore, without considering the impact of other DCI fields, the number of bits in the frequency domain resource indication information remains constant for different frequency domain resource structures, which can keep the DCI size consistent. This eliminates the need for the communication system to design different DCI formats for different frequency domain resource structures, reduces the number of DCI formats, and reduces the computational complexity and time consumption of terminal devices when blindly detecting PDCCHs.

[0181] The above embodiment describes the resource indication method on the terminal device side. Next, the resource indication method on the network device side will be described in detail.

[0182] Each embodiment will be described in detail below.

[0183] FIG13 shows a flow chart of a resource indication method provided by an exemplary embodiment of the present application. This embodiment is illustrated by taking the method as being executed by a network device. The method includes:

[0184] Step 1301: The network device sends frequency domain resource indication information (which may be referred to as frequency domain resource indication or frequency domain resource allocation).

[0185] The frequency domain resource indication information is used to determine the frequency domain resource location of the physical channel. In some embodiments, the frequency domain resource indication information is carried in a first information field of the DCI, which is a frequency domain resource allocation (FDRA) field.

[0186] In some embodiments, the physical channel includes at least one of an uplink channel, a downlink channel, and a side channel, but is not limited thereto. The embodiments of the present application do not specifically limit this.

[0187] The number of bits of the frequency domain resource indication information is determined based on the first frequency domain bandwidth, and the valid bits of the frequency domain resource indication information are determined based on the second frequency domain bandwidth; wherein the first frequency domain bandwidth includes the second frequency domain bandwidth.

[0188] Valid bits refer to bits that can be used to determine the frequency domain resources of the physical channel. Alternatively, valid bits refer to bits that need to be used or parsed when parsing the frequency domain resource indication information, and bits other than the valid bits need to be trimmed or discarded.

[0189] The first frequency domain bandwidth refers to the bandwidth of a BWP. The first frequency domain bandwidth is the bandwidth of the BWP activated by the terminal device. In some embodiments, the terminal device is configured with multiple BWPs, but only one BWP is activated at a time (i.e., the first frequency domain bandwidth). The first frequency domain bandwidth is typically represented by the number of RBs in the BWP.

[0190] The second frequency domain bandwidth is a bandwidth used for a physical channel in the BWP.

[0191] Furthermore, the second frequency domain bandwidth is a bandwidth used for a physical channel in an activated BWP.

[0192] In some subframes, all bandwidth in the BWP is used for the same physical channel, such as a downlink channel. In some subframes, the BWP is divided into multiple subbands, with different subbands used for different physical channels, such as the first subband for a downlink channel and the second subband for an uplink channel. When the physical channel configured by the network device to the terminal device is an uplink channel, the second frequency domain bandwidth is the bandwidth used for the uplink channel in the BWP. When the physical channel configured by the network device to the terminal device is a downlink channel, the second frequency domain bandwidth is the bandwidth used for the downlink channel in the BWP. When the physical channel configured by the network device to the terminal device is a sidelink channel, the second frequency domain bandwidth is the bandwidth used for the sidelink channel in the BWP.

[0193] In some embodiments, the second frequency domain bandwidth refers to the bandwidth of the physical channel indicated by the frequency domain resource indication information in the BWP.

[0194] For example, taking the physical channel as a downlink channel as an example, when both uplink and downlink channels exist in the same subframe, that is, when the subframe can simultaneously send and receive data, the second frequency domain bandwidth is the bandwidth used for downlink transmission in the BWP. The second frequency domain bandwidth is represented by the number of RBs contained in the bandwidth used for downlink transmission in the BWP. When all channels in the same subframe are downlink channels, the second frequency domain bandwidth is the bandwidth of the BWP, that is, the second frequency domain bandwidth is equal to the first frequency domain bandwidth.

[0195] In some embodiments, the second frequency domain bandwidth is a continuous bandwidth.

[0196] For example, taking the physical channel as a downlink channel as an example, when an uplink channel and a downlink channel exist simultaneously in the same subframe, that is, when the subframe can send and receive data at the same time, the second frequency domain bandwidth is the continuous bandwidth for downlink transmission in the BWP, and the second frequency domain bandwidth is usually expressed by the number of RBs contained in the continuous bandwidth for downlink transmission in the BWP.

[0197] In some embodiments, the second frequency domain bandwidth refers to a discrete bandwidth.

[0198] For example, taking the physical channel as a downlink channel as an example, when an uplink channel and a downlink channel exist simultaneously in the same subframe, that is, when the subframe can send and receive data at the same time, the second frequency domain bandwidth is the discrete bandwidth for downlink transmission in the BWP, and the second frequency domain bandwidth is usually expressed by the number of RBs contained in the discrete bandwidth for downlink transmission in the BWP.

[0199] In some embodiments, when data is received on different subbands in the same subframe, the second frequency domain bandwidth is the bandwidth of the BWP, that is, the second frequency domain bandwidth is equal to the first frequency domain bandwidth.

[0200] In summary, the technical solution provided by the embodiment of the present application is that the network device sends frequency domain resource indication information for determining the frequency domain resource position of the physical channel, the number of bits of the frequency domain resource indication information is determined based on the first frequency domain bandwidth, and the effective bit position of the frequency domain resource indication information is determined based on the second frequency domain bandwidth. On the one hand, the number of bits of the frequency domain resource indication information is still determined based on the first frequency domain bandwidth, because the frequency domain resource indication information is usually carried in the DCI. Therefore, when the frequency domain resource structure of the frequency domain resources scheduled by the DCI is different, the number of bits in the information domain of the frequency domain resource indication information in the DCI can be guaranteed to be the same; on the other hand, the effective bit position in the frequency domain resource indication information is determined based on the second frequency domain bandwidth, so that when the terminal device includes frequency domain resources of different transmission directions in the frequency domain resource structure, the frequency domain resources configured for the physical channel are determined based on the effective bit position, thereby avoiding the network device sending frequency domain resource indication information with different bit numbers according to different frequency domain resource structures.

[0256] For example, taking the fixed value as 0, the number of bits of the frequency domain resource indication information is M, the number of valid bits in the frequency domain resource indication information is m, and the Mm bits in the frequency domain resource indication information are set to 0.

[0257] In some embodiments, the size of a resource block group (RBG) within the second frequency domain bandwidth is determined based on the second frequency domain bandwidth; or,

[0258] The size of the RBG within the second frequency domain bandwidth is determined based on the first frequency domain bandwidth.

[0259] RBG refers to a set of RBs.

[0260] For example, when an uplink channel and a downlink channel exist simultaneously in the same subframe, the size of the RBG within the second frequency domain bandwidth is determined based on the second frequency domain bandwidth.

[0261] In the case that all channels in the same subframe are downlink channels, the size of the RBG in the second frequency domain bandwidth is determined based on the first frequency domain bandwidth.

[0262] In some embodiments, the frequency domain resource indication information is carried in the first information field of the downlink control information.

[0263] In some embodiments, the frequency domain resource indication information is used to determine the frequency domain resource position of the downlink channel, wherein the number of bits of the frequency domain resource indication information is determined based on the first frequency domain bandwidth and the frequency domain resource indication method.

[0264] For example, when the frequency domain resource indication mode is resource allocation mode 0, the number of bits of the frequency domain resource indication information is: N RBG , where N RBG Indicates BWP The number of RBGs composed of RBs.

[0265] When the frequency domain resource indication mode is resource allocation mode 1, the number of bits of the frequency domain resource indication information is:

[0266] In some embodiments, when the frequency domain resource indication mode is resource allocation mode 1 and resource mapping adopts the "dynamic switching" mode, the number of bits of the frequency domain resource indication information is:

[0267] In some embodiments, the frequency domain resource indication information is used to determine the frequency domain resource position of the downlink channel, wherein the number of bits of the frequency domain resource indication information is determined based on the second frequency domain bandwidth and the frequency domain resource indication method.

[0268] For example, when the frequency domain resource indication mode is resource allocation mode 0, the effective number of bits of the frequency domain resource indication information is: N′ RBG , where N′ RBG express The number of RBGs composed of RBs.

[0269] When the frequency domain resource indication mode is resource allocation mode 1, the effective number of bits of the frequency domain resource indication information is:

[0270] In some embodiments, when the frequency domain resource indication mode is resource allocation mode 1 and resource mapping adopts the "dynamic switching" mode, the effective number of bits of the frequency domain resource indication information is:

[0271] In some embodiments, the size of the RBG within the second frequency domain bandwidth is determined based on the second frequency domain bandwidth; or, the size of the RBG within the second frequency domain bandwidth is determined based on the first frequency domain bandwidth.

[0272] The size of the RBG within the second frequency domain bandwidth is determined based on the second frequency domain bandwidth, so that the scheduling granularity of the network device for non-overlapping subband full-duplex (SBFD) terminal devices is consistent with the scheduling granularity of non-SBFD terminal devices, thereby avoiding resource fragmentation.

[0273] In some embodiments, the network device indicates the frequency domain resources of the physical channel through valid bits in the frequency domain resource indication information.

[0274] In some embodiments, the network device indicates the frequency domain resources of the uplink channel through valid bits in the frequency domain resource indication information.

[0275] For example, the frequency domain resource indication information is used to determine the frequency domain resource position of the uplink channel. The number of bits of the frequency domain resource indication information is J. The valid bits in the frequency domain resource indication information used to indicate the frequency domain resource position of the uplink channel are K. The JK bits other than the valid bits of the frequency domain resource indication information are 0 or 1. Then, the network device indicates the frequency domain resources of the uplink channel through the K valid bits in the frequency domain resource indication information.

[0276] In some embodiments, the network device indicates the frequency domain resources of the downlink channel through valid bits in the frequency domain resource indication information.

[0277] For example, the frequency domain resource indication information is used to determine the frequency domain resource position of the downlink channel, the number of bits of the frequency domain resource indication information is J, the valid bits used to indicate the frequency domain resource position of the downlink channel in the frequency domain resource indication information are K, and the JK bits other than the valid bits of the frequency domain resource indication information are 0 or 1. Then, the network device indicates the frequency domain resources of the downlink channel through the K valid bits in the frequency domain resource indication information.

[0278] In some embodiments, the network device indicates the frequency domain resources of the sidelink channel through valid bits in the frequency domain resource indication information.

[0279] For example, the frequency domain resource indication information is used to determine the frequency domain resource position of the side channel between the terminal devices, the number of bits of the frequency domain resource indication information is J, the valid bits used to indicate the frequency domain resource position of the side channel in the final frequency domain resource indication information are K, and the JK bits other than the valid bits of the frequency domain resource indication information are set to 0 or 1. Then, the first terminal device indicates the frequency domain resources of the side channel between the first terminal device and the second terminal device based on the K valid bits in the frequency domain resource indication information.

[0280] In some embodiments, in repeated transmission, the second frequency domain bandwidth is determined based on the bandwidth of the physical channel corresponding to the transmission direction in the first transmission of the repeated transmission or the last transmission of the repeated transmission.

[0281] Exemplarily, when the physical channel is a downlink channel, in at least two repeated transmissions, the second frequency domain bandwidth includes the frequency domain bandwidth occupied by the downlink channel in the first transmission of the repeated transmission; or, the second frequency domain bandwidth includes the frequency domain bandwidth occupied by the downlink channel in the last transmission of the repeated transmission.

[0282] Exemplarily, when the physical channel is an uplink channel, in at least two repeated transmissions, the second frequency domain bandwidth includes the frequency domain bandwidth occupied by the uplink channel in the first transmission of the repeated transmission; or, the second frequency domain bandwidth includes the frequency domain bandwidth occupied by the uplink channel in the last transmission of the repeated transmission.

[0283] In at least two repeated transmissions, the bandwidth of the physical channel corresponding to the transmission direction in the first transmission or the last transmission in the repeated transmission is determined as the second frequency domain bandwidth, supporting multiple repeated transmissions to use the same frequency domain resources for data transmission, reducing the complexity of data transmission, and improving the simplicity of data transmission.

[0284] In summary, the technical solution provided by the embodiment of the present application is that the network device sends frequency domain resource indication information for determining the frequency domain resource position of the physical channel, the number of bits of the frequency domain resource indication information is determined based on the first frequency domain bandwidth, the effective bit position of the frequency domain resource indication information is determined based on the second frequency domain bandwidth, and the network device indicates the frequency domain resources of the physical channel through the effective bit position in the frequency domain resource indication information. On the one hand, the number of bits of the frequency domain resource indication information is still determined based on the first frequency domain bandwidth, because the frequency domain resource indication information is usually carried in the DCI. Therefore, when the frequency domain resource structure of the frequency domain resources scheduled by the DCI is different, the number of bits in the information domain of the frequency domain resource indication information in the DCI can also be guaranteed to be the same; on the other hand, the effective bit position in the frequency domain resource indication information is determined based on the second frequency domain bandwidth, so that when the terminal device includes frequency domain resources of different transmission directions in the frequency domain resource structure, the frequency domain resources configured for the physical channel are determined based on the effective bit position, thereby avoiding the network device sending frequency domain resource indication information with different bit numbers according to different frequency domain resource structures.

[0285] Furthermore, without considering the impact of other DCI fields, the number of bits in the frequency domain resource indication information remains constant for different frequency domain resource structures, which can keep the DCI size consistent. This eliminates the need for the communication system to design different DCI formats for different frequency domain resource structures, reduces the number of DCI formats, and reduces the computational complexity and time consumption of terminal devices when blindly detecting PDCCHs.
