[0002] In the New Radio (NR) standard of the fifth generation wireless access system, the basic unit in the frequency domain is a subcarrier, and the basic unit in the time domain is an Orthogonal Frequency Division Multiplexing (OFDM) symbol. A Resource Element (RE) is the smallest physical resource, which contains one subcarrier within one OFDM symbol.

[0003] Specifically, the network device can configure one or more downlink / uplink bandwidth regions (BWPs) for a terminal device, the BWP is a subset of the system carrier bandwidth, and the multiple bandwidth regions can overlap in the frequency domain. The network can activate one of the downlink / uplink bandwidth regions from the configured bandwidth regions for the terminal device (UE), and transmit a physical downlink shared channel (PDSCH) and a physical downlink control channel (PDCCH) to the terminal device in the activated downlink bandwidth region, while the terminal device transmits an uplink shared channel (PUSCH) to the network in the activated uplink bandwidth region.

[0070] Common index region: a set of contiguous physical resource blocks in frequency domain obtained according to the common index mechanism Common index scheme.

[0071] Further, a possible structure diagram of the above network device can be as followsFigure 2 The network device 102 can be capable of performing the methods provided by embodiments of the present application. The network device 102 can include a controller or processor 201 (hereinafter referred to as processor 201) and a transceiver 202. The controller / processor 201 is also sometimes referred to as a modem processor. The modem processor 201 can include a baseband processor (BBP) (not shown) that processes digitized received signals to extract information or data bits conveyed in the signals. As such, the BBP generally implements one or more digital signal processor(s) (DSP(s)) within the modem processor 201 or as a separate integrated circuit (IC) as desired or expected.

[0072] The transceiver 202 can be used to support the transceiving of information between the network device and terminal devices, and to support radio communication between terminal devices. The processor 201 can also be used to perform various functions of terminal devices in communication with other network devices. On the uplink, uplink signals from the terminal devices are received via an antenna, modulated by the transceiver 202, and further processed by the processor 201 to recover the traffic data and / or signaling information sent by the terminal devices.

[0073] Optionally, the network device can also include a bus. The transceiver 202, the memory 203, and the communication unit 204 can be connected to the processor 201 via the bus. For example, the bus can be a Peripheral Component Interconnect (PCI) bus or an Extended Industry Standard Architecture (EISA) bus, etc. The bus can include an address bus, a data bus, and a control bus, etc.

[0074]

[0075] ​Figure 3 Fig. 1 shows a possible architecture of a terminal device in the communication system described above. The terminal device is capable of performing the method provided by the embodiments of the present application. The terminal device can be any one of the one or more terminal devices in Fig. 1. The terminal device comprises a transceiver 301, an application processor 302, a memory 303 and a modem processor 304. Figure 1

[0076] The transceiver 301 can condition (e.g., filter, amplify, downconvert, and digitize) a signal received from the antenna and provide input samples. On the uplink, the transceiver 301 can condition (e.g., filter, amplify, upconvert, and convert to analog) the output samples and provide a signal to the antenna for transmission.

[0077] The modem processor 304, also sometimes referred to as a controller or processor, can include a baseband processor (BBP) (not shown) that processes the digitized received signal to extract the information or data bits conveyed in the signal. The BBP is generally implemented in one or more digital chips or as a separate integrated circuit (IC) as needed or as desired in the modem processor 304.

[0078] In one design, the modem processor 304 can include an encoder 3041, a modulator 3042, a decoder 3043, and a demodulator 3044. The encoder 3041 is configured to encode a signal to be transmitted. For example, the encoder 3041 can be configured to receive traffic data and / or signaling messages to be sent on the uplink and process (e.g., format, encode, or interleave, etc.) the traffic data and signaling messages. The modulator 3042 is configured to modulate the output signal of the encoder 3041. For example, the modulator can perform symbol mapping and / or modulation, etc., on the output signal (data and / or signaling) of the encoder and provide output samples. The demodulator 3044 is configured to demodulate an input signal. For example, the demodulator 3044 processes the input samples and provides symbol estimates. The decoder 3043 is configured to decode the demodulated input signal. For example, the decoder 3043 processes (e.g., deinterleaves, and / or decodes, etc.) the demodulated input signal and outputs decoded signals (data and / or signaling). The encoder 3041, the modulator 3042, the demodulator 3044, and the decoder 3043 can be implemented by a composite modem processor 304. These units process the signals based on the radio access technology employed by the wireless access network.

[0079] ​The modem processor 304 receives digitized data, which can represent voice, data, or control information, from the application processor 302 and processes the digitized data for transmission. The modem processor can support one or more of multiple wireless communication protocols for multiple communication systems, such as LTE, New Radio, Universal Mobile Telecommunications System (UMTS), High Speed Packet Access (HSPA), etc. Optionally, one or more memories can also be included in the modem processor 304.

[0080] Optionally, the modem processor 304 and the application processor 302 can be integrated in one processor chip.

[0081] The memory 303 is used to store program code (sometimes also called program, instruction, software, etc.) and / or data for supporting communication of the terminal device.

[0082] It should be noted that the memory 203 or the memory 303 can include one or more memory units, for example, can be a memory unit inside the processor 201 or the modem processor 304 or the application processor 302 for storing program code, or can be an external memory unit independent of the processor 201 or the modem processor 304 or the application processor 302, or can also be a component including a memory unit inside the processor 201 or the modem processor 304 or the application processor 302 and an external memory unit independent of the processor 201 or the modem processor 304 or the application processor 302.

[0083] The processor 201 and the modem processor 304 (hereinafter referred to as the processor 304) can be the same type of processor or different types of processors. For example, the processor 201 and the processor 304 can be implemented with one or more Central Processing Units (CPUs), general-purpose processors, Digital Signal Processors (DSPs), Application-Specific Integrated Circuits (ASICs), Field Programmable Gate Arrays (FPGAs), another programmable logic device, a transistor logic device, hardware components, an integrated circuit, or any combination thereof. The processor 201 and the processor 304 can be a combination of computing devices, such as a combination of one or more microprocessors, a combination of a DSP and a microprocessor, or a combination of a system on chip (SoC) and the like.

[0084] Those skilled in the art can understand that various illustrative logical blocks, modules, circuits, and algorithms described in connection with the aspects disclosed herein can be implemented as electronic hardware, instructions stored in memory or in another computer-readable medium and executed by a processor or other processing device, or combinations of both. The devices described herein can be used in any circuit, hardware component, IC, or IC chip, as an example. The memory disclosed herein can be any type and size of memory and can be configured to store any type of information required. To clearly illustrate this interchangeability, various illustrative components, blocks, modules, circuits, and steps have been described above generally in terms of their functionality. How such functionality is implemented depends on the particular application, design choices, and / or design constraints imposed on the overall system. Skilled artisans can implement the described functionality in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the present disclosure.

[0085] In the embodiments of the present application, transmitting a downlink (uplink) channel can refer to transmitting data or information carried on the downlink (uplink) channel, where the data or information can refer to data or information after channel coding.

[0086] For example, in order to improve the blind detection efficiency of the terminal device, the concept of control resource set (CORESET) is proposed in NR. The network device divides one or more control resource sets for each terminal device, and sends a control channel to the terminal device on any control resource set corresponding to the terminal device. The terminal device accesses the service cell to obtain the information of the resource block set (RB set) included in the CORESET in the frequency domain, and the resource block set included in the control resource set is located in one downlink BWP. In NR, the resource block set in the frequency domain has a granularity of 6 contiguous resource blocks (RBs) for control resource allocation.

[0087] Generally, the resources occupied by the BWP in the frequency domain can be configured by the exclusive signaling of the terminal device, such as RRC signaling, which is not limited here. A terminal device can be configured with a maximum of 4 BWPs for downlink transmission, and can also be configured with a maximum of 4 BWPs for uplink transmission; and the configurations of the BWPs of different terminal devices can be different, and only one uplink / downlink BWP is activated for transmission in actual transmission. The resources of the bandwidth area BWP are located within the system carrier bandwidth, and the number of physical resource blocks in the common index area included in the system carrier can be determined according to Table 1 below, wherein the terminal device receives indication information indicating the subcarrier width μ, and determines the number of physical resource blocks in the common index area according to μ and Table 1; or receives a notification from the network device to determine, or according to the provisions of the standard or protocol, which is not limited here, and the following is an example of table lookup.

[0088] Table 1

[0089] μ Number of physical resource blocks 0 275 1 275 2 275 3 275 4 138 5 69

[0090] wherein μ corresponds to the size of subcarrier width, as shown in Table 2. For example, μ = 0 corresponds to a physical resource block of 275, and the common resource block index (Common RB index) is from number {0} to number {274}, i.e., {0, 1, 2, 3, …, 274}. The Common RB index is used to configure the resource occupied by the BWP in the frequency domain, wherein a BWP includes a set of resource blocks that are continuous in the frequency domain, and the minimum granularity in the frequency domain is 1 resource block. The Common RB index can be configured by the network device, and for a given subcarrier width, the network device configures the offset of the RB numbered 0 in the Common RB index relative to the frequency domain reference point, wherein the frequency domain reference point is a frequency domain location that is pre-configured or defined, or notified by the network device (e.g., high layer signaling), wherein the frequency domain reference point can be one of the following: the smallest numbered physical resource block included in the synchronization / broadcast channel block (SS / PBCH Block) in the primary cell (Pcell), the uplink frequency domain location notified by the system information in the primary cell (Pcell), the frequency domain location indicated by the secondary cell configuration information in the secondary cell (Scell), and the frequency domain region indicated by the secondary uplink (SUL) frequency domain configuration information in the secondary uplink (SUL) frequency domain, without specific limitation here.

[0091] Table 2

[0092] μ Subcarrier width 0 15 1 30 2 60 3 120 4 240 5 480

[0093] For example, the network device configures 1 BWP for two terminal devices UE0 and UE1, i.e., BWP0 and BWP1, respectively. The resource of BWP0 is 14 frequency-domain continuous resource blocks from RB number {1} to RB number {14} in Common RB index, i.e., the resource blocks corresponding to Common RB index {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14}. The resource of BWP1 is 12 frequency-domain continuous resource blocks from RB number {12} to RB number {23} in Common RB index, i.e., the resource blocks corresponding to RB number {12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23} in Common RB index, as shown in Figure 4 BWP0 includes Common RB index {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14}, and the corresponding BWP RB index is {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13}. Similarly, the BWP RB index corresponding to BWP1 can also start from 0.

[0094] Specifically, the network device can configure BWP0 as the bandwidth region of UE0, and BWP1 as the bandwidth region of UE1, or BWP0 and BWP1 as two candidate bandwidth regions configured by the network device for the same UE. There can be more BWP2, BWP3, etc. in the actual scenario, which is not limited here. In order to avoid the collision of control channel resources caused by the occupation of the same RB in different BWPs. Further, when performing CORESET resource allocation in BWP0 and BWP1 and more BWPs, only one CORESET resource of one BWP is configured on the overlapping RB resource. The following is an example explanation. Figure 5

[0095] In Figure 5 , the resource indication information is used to indicate a plurality of resource blocks for the terminal device, which can be indicated in the form of a bitmap. Each bit in the bitmap corresponds to 6 resource blocks (taking 6 resource blocks as an example for the resource allocation granularity of RE set). BWP0 includes CORESET0 and the resource allocation indication information of the bitmap is {`100`}, i.e., the physical resource block numbers of BWP0 included by CORESET0 are {0, 1, 2, 3, 4, 5}; BWP1 includes CORESET1 and the resource allocation indication information of the bitmap is {`11`}, i.e., the physical resource block numbers of BWP1 included by CORESET1 are {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11}.

[0096] ​As the RB numbers {10, 11, 12, 13} of the CORESET0 correspond to the Common RB index of the RB numbers {0, 1, 2, 3} in the CORESET1, as shown in Figure 4 In the BWP0, the RB numbers {10, 11, 12, 13} cannot be allocated to the CORESET0, and since the CORESET resource allocation granularity is 6 RBs, the four RBs with the RB numbers {6, 7, 8, 9} in the BWP0 cannot be used for the CORESET0 in the BWP0 due to not meeting the resource allocation granularity size (6 RBs) and cannot be allocated to other BWPs. Therefore, the RB numbers {6, 7, 8, 9} in the BWP0 become resource fragments, resulting in reduced spectral utilization.

[0097] Since the resource granularity (6 RBs) of the CORESET in the frequency domain does not match the resource granularity (1 RB) of the bandwidth area in the frequency domain, there are resource fragments that cannot be used to configure the CORESET in a bandwidth area, reducing the spectral utilization. The same problem exists in the transmission of data channels.

[0098] It should be noted that the present embodiment relates to the term "starting resource block", which can mean the resource block with the smallest corresponding subcarrier number among the resource blocks included in a certain area (for example, a common index area or a bandwidth area), or the resource block with the smallest number when the included resource blocks are numbered from low frequency to high frequency; or the resource block with the largest corresponding subcarrier number among the resource blocks included in a certain area (for example, a common index area or a bandwidth area), or the resource block with the largest number when the included resource blocks are numbered from low frequency to high frequency, wherein the low frequency and the high frequency are defined relative to the subcarrier number, and the subcarrier number at the low frequency position is smaller than the subcarrier number at the high frequency position. In the embodiment, no specific limitation is made, and the actual communication system requirements, network device notification, or standard or protocol provisions are used as the reference.

[0099] It should also be noted that the present embodiment relates to the expressions "first bit", "second bit", "last bit", and the like. The "first bit" means the most significant bit (MSB) among multiple bits, the "second bit" means the most significant bit other than the MSB among multiple bits, and so on. The "last bit" means the least significant bit (LSB) among multiple bits. The present embodiment uses the first and second and similar expressions to facilitate the description of the scheme.

[0100] It should be noted that there can be a corresponding relationship between any two or more of the following: the frequency domain position of the starting resource block of the common index region, the frequency domain position of the frequency domain reference point, the number of resource blocks of the common index region, the starting resource block position of the BWP, the number of resource blocks contained in the BWP, and the subcarrier width. The corresponding relationship can be defined by a standard or protocol, determined by a network device, or obtained by a network device, which is not limited here. These mapping relationships do not affect the implementation of the embodiments of the present application, and all possible mappings are covered by the embodiments of the present application.

[0101] For example, the starting resource block of the common index region is the same or different relative to the frequency domain position of the frequency domain reference point for different subcarrier widths.

[0102] For another example, the starting resource blocks of the multiple common index regions of the multiple BWPs are aligned or not aligned in the frequency domain, and the subcarrier widths configured by the multiple BWPs are the same or different.

[0103] The embodiments of the present application will be further described in detail below based on the common aspects of the present application described above. In the description of the embodiments, the time delay between uplink and downlink is ignored, and it is assumed that the transmission time of the network device is the same as the reception time of the terminal device. For the processing corresponding to the transmission of the network device and the reception of the terminal device, the embodiments are described mainly from the perspective of the terminal device. It can be understood by those skilled in the art that the reception of the terminal device from the network device means that the network device has transmitted. In the present application, the term "resource block unit" is used, which can be understood by those skilled in the art as a logical division of resource blocks, which facilitates resource allocation according to the corresponding resource allocation granularity, and can cover other expressions for resource block division.

[0104] In addition, the numbering of the steps in the embodiments of the present application does not limit the order of execution in the specific process, and the order of execution of the above steps will be adjusted adaptively in different optional designs. The values of the parameters represented by letters involved in the embodiments of the present application are all non-negative integers, i.e., the values indicated by the letters are all non-negative integers.

[0105] Embodiment 1

[0106] The embodiments of the present application provide a communication method, in which a terminal device obtains resource indication information, and the resource indication information indicates multiple resource blocks for the terminal device; and the terminal device determines index information of the multiple resource blocks. According to the method provided by the embodiments of the present application, the network device can efficiently allocate or reallocate uplink or downlink resources for one or more terminal devices, and improve the processing efficiency of the terminal device.

[0107] Figure 6An embodiment of the present application is shown in the following Figure 6 The solution provided by Embodiment 1 of the present application is described.

[0108] Step 600: The network device determines a plurality of resource blocks, which are configured for the first terminal device;

[0109] Optionally, the network device further configures a plurality of resource blocks for the second terminal device, which are partially collided with or not collided with the plurality of resource blocks. For the sake of convenience, the description of any terminal device configured with the plurality of resource blocks by the network device is simplified as a terminal device hereinafter.

[0110] The determining and / or configuring step can be performed by the processor 201 of the network device.

[0111] Step 601: The network device sends resource indication information to the terminal device, which is used to indicate the plurality of resource blocks in step 600.

[0112] The step can be performed by the transceiver 202 of the network device, or controlled by the processor 201 of the network device to perform the transceiver 202.

[0113] Optionally, the resource indication information can include a plurality of bits, for example, a bitmap. Each bit in the plurality of bits is used to indicate whether at least one resource block (when the at least one resource block is a plurality of resource blocks, the plurality of resource blocks are a plurality of resource blocks in frequency domain) is used for the terminal device. Specifically, when the value of the bit is 0, the value of the bit is used to indicate that the at least one resource block corresponding to the bit is not available for the terminal device; when the value of the bit is 1, the value of the bit is used to indicate that the at least one resource block corresponding to the bit is available for the terminal device.

[0114] The resource indication information can include a plurality of bits with the value of 1, and a set of at least one resource block corresponding to these bits is configured for the terminal device.

[0115] It should be noted that the number of the plurality of bits included in the resource indication information, and the position of the at least one resource block corresponding to each bit and the number of resource blocks are different according to different configuration modes, which will be exemplarily described hereinafter. For the sake of convenience, the number of bits included in the resource indication information is referred to as S, and S is a positive integer.

[0116] It should be noted that the network device can configure multiple sets of candidate resource blocks for each terminal device, for example, configure multiple candidate BWP, and each candidate BWP contains resource blocks available to the terminal device. The multiple resource blocks mentioned herein refer to resource blocks in a set of candidate resource blocks or in a certain BWP of the multiple candidate BWP. The terminal device determines to send a data channel to the network device through a set of resource blocks in the multiple sets of candidate resource blocks, or to receive or send a control channel from the network device.

[0117] Optionally, the resource indication information is frequency domain resource configuration information of a control resource set (CORESET), for example, a resource block set (RB set), or the resource indication information is frequency domain resource configuration information of a data resource set, for example, frequency domain resource configuration information of a physical uplink shared channel (PUSCH) and / or a physical downlink shared channel (PDSCH).

[0118] In step 602, the terminal device acquires resource indication information, and the resource indication information indicates multiple resource blocks for the terminal device.

[0119] The acquisition step can be performed by the transceiver 301 or the processor 304 of the terminal device, or by the processor 304 controlling the transceiver 301 to perform.

[0120] In step 603, the terminal device determines index information of the multiple resource blocks.

[0121] The index information can be index information of the multiple resource blocks in a common index region, or index information in a bandwidth region.

[0122] Optionally, the index information of the multiple resource blocks can be resource block numbers of one or more resource blocks in the multiple resource blocks. For example, the index information of other resource blocks in the multiple resource blocks can be determined by the index information of the starting resource block of the multiple resource blocks; for another example, the positions of the multiple resource blocks can be determined by the index information of the starting resource block of the multiple resource blocks, without determining the index information of all resource blocks in the multiple resource blocks.

[0123] The determination step can be performed by the processor 304 of the terminal device.

[0124] Specifically, after the terminal device determines the index information of the multiple resource blocks, the terminal device receives a control or data channel sent by the network device on the multiple resource blocks, or sends a data channel to the network device.

[0125] The communication method implemented through the steps 600-603 can enable the network device to notify the terminal device of the allocated or re-allocated downlink or uplink resource through the resource indication information, so that the terminal device can efficiently obtain the resource position in time, and improve the processing efficiency of the terminal device.

[0126] It should be noted that the determination operation of the network device in the embodiment 1 of the present application can be performed by the processor 201, the transceiving operation of the network device can be performed by the transceiver 202, or controlled by the processor 201 to perform through the transceiver 202; the determination operation of the terminal device can be performed by the processor 304, the acquisition operation of the terminal device can be performed by the processor 304 or the transceiver 301, or controlled by the processor 304 to perform through the transceiver 301, depending on the acquisition method, and the transceiving operation of the terminal device can be performed by the transceiver 301.

[0127] In the embodiment 1 of the present application, the index of the plurality of resource blocks for the terminal device can be configured according to the resource block index of the common index region (Common RB index) or the resource block index of the bandwidth region (BWP RB index). The specific configuration method can be determined by the network device, or determined according to the standard or protocol, or determined in other ways, which is not limited here. The starting resource block of the BWP can have a certain offset relative to the starting resource block of the common index region, which is referred to as the second offset in the following. It should be noted that when the resource block indexes of the common index region and the BWP region are independently set, i.e., numbered respectively, the resource block indexes of the common index region and the resource block indexes of the BWP can all start from any number, such as 0 or 1, and the embodiment 1 of the present application does not make specific limitation, and is mainly exemplified by starting from 0 in the specific implementation mode.

[0128] In the first optional design, the index of the plurality of resource blocks for the terminal device is configured according to the Common RB index. In this optional design, the index of one or more BWPs configured on the resource blocks of the common index region can follow the Common RB index, or a new BWP RB index can be defined, such as starting from RB0, but the index of the plurality of resource blocks for the terminal device is configured according to the Common RB index.

[0129] Optionally, the method further comprises step 6021: the terminal device acquires a first offset, the first offset being an offset between a starting resource block of the common index region and a frequency domain reference point, the offset can be an offset RB number. Wherein, the frequency domain reference point is explained above. The first offset corresponding to different subcarrier widths can be the same or different, which is not specifically limited here.

[0130] Optionally, the terminal device further acquires the number of resource blocks of the common index region. The specific acquisition manner of the number of resource blocks is described above for the number of resource blocks of the common index region, which is not specifically limited here. The terminal device can acquire the number of resource blocks in any manner. For the convenience of description, the number of resource blocks of the above common index region is referred to as X1 in embodiment 1 of the application.

[0131] Optionally, the network device sends the first offset to the terminal device, and the terminal device receives the first offset from the network device, for example, through high layer signaling, which can be RRC signaling, or the terminal device determines the first offset through a pre-configured table or a corresponding relationship. The corresponding relationship can be a corresponding relationship between the first offset and the subcarrier width, or other corresponding relationships that can be used to acquire the first offset; or the first offset can also be acquired according to an indication or other values corresponding to the first offset.

[0132] Optionally, the first offset can be an RB number, that is, the first offset is an RB number of the starting resource block of the common index region relative to the frequency domain reference point.

[0133] In the first possible implementation, the configuration of the plurality of resource blocks is aligned with the starting resource block of the common index region as a boundary.

[0134] In this possible implementation, the first bit of the S bits is used to indicate whether the n resource blocks starting from the starting resource block in the common index region are used for the terminal device.

[0135] Wherein, the value of n is equal to m, and the m is a resource allocation granularity, which can be pre-configured, or determined or notified to the terminal device by the network device, and m is a positive integer.

[0136] For example, in NR, the allocation granularity of RB set of CORESET in the frequency domain is 6 consecutive RBs, and resources less than 6 consecutive RBs cannot be used for resource allocation of RB set, so m is equal to 6.

[0137] For example, the resource configuration manner is described in the following example. Figure 7 , Figure 7According to the Common RB index configuration, the plurality of resource blocks are, for example, 24 RBs, and are aligned with the starting resource block of the common index region as the boundary. In this case, the first four bits of the S bits respectively indicate 6 RBs that are continuous in the frequency domain, and the first bit indicates 6 RBs that are continuous from the starting resource block. Optionally, if the number of the plurality of resource blocks is not an integer multiple of 6, the last resource block unit contains less than 6 resource blocks.

[0138] For another example, for the resource configuration of a data channel, such as a physical downlink shared channel (PDSCH) and a physical uplink shared channel (PUSCH), the allocation granularity is a resource block group (RBG), but the RBG size (i.e., the number of RBs contained in each RBG) can be related to the BWP bandwidth, and each BWP can correspond to multiple different RBG sizes. The correspondence can be pre-configured or determined by the network device. Optionally, the correspondence can be embodied in the form of a table, such as Table 3 below. Each item in the table corresponds to a BWP bandwidth size, such as the number of RBs, and each item contains the configuration of two REG sizes. Therefore, the value of m needs to be determined according to related parameters such as the BWP bandwidth, and in the case where the BWP corresponds to multiple RBG sizes, the network device also needs to determine one of the RBG sizes as m and notify the terminal device. The notification method can be high-layer signaling, such as RRC signaling. For example, m can be 1, 2, 4, 8, 3, 6, or 12.

[0139] Table 3

[0140] BWP bandwidth Config 1 Config 2 X0–X1 RBs RBG size 1 RBG size 2 X1+1–X2 RBs RBG size 3 RBG size 4 … … …

[0141] Optionally, the second bit of the S bits is used to indicate whether the m resource blocks adjacent to the n resource blocks indicated by the first bit of the S bits are used by the terminal device.

[0142] Further optionally, the third bit of the S bits indicates the m resource blocks adjacent to the m resource blocks indicated by the second bit.

[0143] In this possible implementation, the value of S can be any of the following:

[0144] Firstly, The represents the floor function.

[0145] Secondly, The represents the ceiling function, and the number of resource blocks indicated by the last bit of the S bits is less than m.

[0146] By the possible implementation, m RBs starting from the starting RB of the common index region can be configured as a resource block unit. The configuration manner can realize that the network device configures resources for multiple terminal devices in a manner of aligning with the boundary of the resource block unit, that is, the network device configures resources for multiple terminal devices or multiple resource blocks as much as possible in the unit of m RBs, so that the boundary of each resource block unit of the terminal device is aligned with the starting RB in the unit of m resource blocks, or the number of RBs offset between the boundary of each resource block unit of the terminal device and the starting RB is a multiple of m, so as to avoid the occurrence of resource block fragments (fragments of less than m RBs) that cannot be allocated as much as possible, and improve the resource utilization efficiency. The boundary can be at least one of a low-frequency boundary resource block and a high-frequency boundary resource block of the resource block unit.

[0147] It should be noted that the division of the resource block unit in the embodiment 1 of the present application is only logical division and is not embodied on the physical resource.

[0148] In the second possible implementation, the configuration of the multiple resource blocks is aligned with the boundary of the frequency domain reference point.

[0149] In the possible implementation, the first bit of the S bits is used to indicate whether n resource blocks starting from the starting resource block of the common index region are used for the terminal device. The value of n is determined according to the first offset and m, and n is greater than 0. The explanation of m is described above and will not be repeated here.

[0150] Optionally, in the case where the value of n is determined according to the first offset and m, n is equal to y1, or the value of n is equal to the difference between m and y1, where the value of y1 is equal to the value of the first offset modulo m, that is, the first offset mod m.

[0151] In the first optional implementation, when the first offset is offset to the low-frequency direction relative to the frequency domain reference point, if y1 is not equal to 0, n is equal to y1, and if y1 is equal to 0, n is equal to the value of m minus y1. In this way, the first bit indicates y1 resource blocks starting from the starting RB, and m RBs are configured as a resource block unit starting from the y1+1th resource block, so as to realize that the frequency domain reference point is located at the boundary of the logical resource block unit allocation.

[0152] For example, when the first offset is in the high frequency direction relative to the frequency domain reference point, the value of n is equal to m minus the difference of y1, where the value of y1 is equal to the value of the first offset modulo m, i.e., the first offset mod m. In this way, the first bit indicates (m-y1) resource blocks starting from the starting RB, and the (m-y1) resource blocks and the y1 RBs in the first offset can form a resource block unit of m resource blocks in quantity, so that the frequency domain reference point is located at the boundary of the logical resource block unit allocation.

[0153] Optionally, a second bit in the S bits is used to indicate whether m resource blocks adjacent to the n resource blocks indicated by the first bit in the S bits are used for the terminal device.

[0154] Further optionally, a third bit in the S bits indicates m resource blocks adjacent to the m resource blocks indicated by the second bit.

[0155] In this possible implementation, the value of S can be any one of the following, depending on the requirements or configurations of the actual communication scenario:

[0156] Firstly, The represents the floor function;

[0157] Secondly, The represents the floor function;

[0158] Thirdly, The represents the ceiling function;

[0159] Fourthly, The represents the ceiling function.

[0160] The difference between this possible implementation and the first possible implementation is the alignment position. The first possible implementation takes the starting RB of the common index region as the alignment position, while the second possible implementation takes the frequency domain reference point as the alignment position, but the processing manner is similar.

[0161] By the possible implementation, the boundary of the resource block unit configured with the frequency domain reference point can be realized. The configuration manner can realize that the network device configures resources for multiple terminal devices in a manner of boundary alignment of the resource block unit, that is, taking the frequency domain reference point as the boundary of the resource block unit for resource configuration in units of m RBs, ensuring that the resource blocks configured for each terminal device are aligned in units of m resource blocks on the boundary relative to the frequency domain reference point, or ensuring that the number of RBs offset between the boundary of each resource block unit configured for the terminal device and the frequency domain reference point is a multiple of m, so as to avoid as much as possible the occurrence of resource block fragments (fragments of less than m RBs) that cannot be allocated, and improve resource utilization efficiency. The boundary can be at least one of a low-frequency boundary resource block and a high-frequency boundary resource block of the resource block unit.

[0162] In a third possible implementation, the index information of the multiple resource blocks determined by the terminal device in step 603 is determined through offset indication information.

[0163] The method further includes step 6023, in which the network device sends offset indication information to the terminal device, and the terminal device acquires the offset indication information. The offset indication information is used to indicate the number Q of RBs offset from a starting resource block of a common index region to a resource indication reference resource block. The resource indication reference resource block can be preconfigured or determined by the network device, or can be specified by a protocol or standard, and can be a first RB or a last RB in at least one resource block indicated by a first bit of resource indication information. Here, the first and last can be the first and last in a low-frequency position, or the first and last in a high-frequency position. The definitions of high frequency and low frequency are described above. In terms of function, the configuration of the resource indication reference resource block is used for the terminal device to determine the index information of the multiple resource blocks.

[0164] For example, the number Q of RBs of the offset is used to indicate Q consecutive resource blocks in a high-frequency direction from the starting resource block of the common index region. For example, when resource blocks are numbered from 0, the Q consecutive resource blocks RB0, RB1, …, RBQ-1 of the common index region are indicated. m-1 The Q is greater than or equal to 0 and less than m. The value of m is described above.

[0165] For another example, when the resource indication reference resource block is the last RB in at least one resource block indicated by a first bit of resource indication information, the first bit of the S bits corresponds to Q consecutive resource blocks starting from the starting RB, and the Q is not 0.

[0166] For example, if the resource indication reference resource block is the first RB in the at least one resource block indicated by the first bit in the resource indication information, if the Q is 0, the first bit of the S bits corresponds to the first m resource blocks in the starting resource block of the common index region; if the Q is not 0, the first bit of the S bits corresponds to the m resource blocks adjacent to the first Q resource blocks in the starting resource block of the common index region.

[0167] Further optionally, the second bit of the S bits corresponds to the m resource blocks adjacent to the resource block corresponding to the first bit in the common index region.

[0168] Optionally, the offset indication information is carried in the downlink control information DCI or high layer signaling, and is notified to the terminal device by the network device, or is notified to the terminal device by the network device in advance and stored by the terminal device.

[0169] Further optionally, the offset indication information can be multiple bits, and the values indicated by the multiple bits represent the number of offset RBs, as shown in Table 4:

[0170] Table 4

[0171] Offset indication information Offset 000 0 RB 001 1 RB 010 2 RB 011 3 RB 100 4 RB 101 5 RB

[0172] Through the possible implementation, the network device indicates the position information of the part of resource blocks indicated by the resource indication information to the terminal device at the same time of sending the resource indication information to the terminal device, so that the terminal device can accurately and efficiently obtain the resource configuration information, and the processing efficiency of the terminal device is improved.

[0173] In the second optional design, the multiple resource blocks for the terminal device are configured according to the resource block index RB index of the BWP.

[0174] Optionally, the method further includes the step 6021 in the first optional design, and details are described above.

[0175] Optionally, the method further includes a step 6022, in which the terminal device obtains a second offset, and the second offset is an offset between the starting resource block of the common index region and the starting resource block of the carrier bandwidth region BWP. The offset can be the number of offset RBs.

[0176] Optionally, the terminal device further acquires the number of resource blocks of the BWP, which can be determined by table lookup, or notified by the network device, or determined according to a standard or protocol, which is not limited here. For example, the number of resource blocks of the BWP can be indicated by high layer signaling, such as RRC signaling. For the convenience of description, the number of resource blocks of the BWP in Embodiment 1 of the application is referred to as X2.

[0177] Further optionally, the network device sends a second offset to the terminal device, and the terminal device receives the second offset from the network device, for example, through high layer signaling, which can be RRC signaling, or the terminal device determines the second offset through a pre-configured table or a corresponding relationship, which can be a corresponding relationship between the second offset and the subcarrier width, or other corresponding relationships that can be used to acquire the second offset, or the second offset can also be acquired according to an indication or other values corresponding to the second offset, which is not limited here.

[0178] Specifically, the second offset can be the number of RBs, that is, the second offset is the number of RBs of the starting resource block of the BWP relative to the starting resource block of the common index region.

[0179] In the first possible implementation, the configuration of the plurality of resource blocks is aligned with the starting resource block of the common index region as a boundary.

[0180] In this possible implementation, the first bit of the S bits is used to indicate whether the continuous n resource blocks starting from the starting resource block in the bandwidth region BWP are used by the terminal device, or the first bit of the S bits is used to indicate whether the m resource blocks adjacent to the continuous n resource blocks starting from the starting resource block in the bandwidth region BWP are used by the terminal device. The value of n is determined according to the value of m and the second offset, and n is greater than 0. The explanation of m is described above and will not be repeated here.

[0181] Since the frequency domain resources of the BWP are part or all of the resource blocks of the frequency domain resources of the common index region. Based on this, the second offset is the offset of the starting resource block of the BWP relative to the starting RB of the common index region in the high frequency direction.

[0182] Specifically, the value of n is equal to the difference between m and y2, and the value of y2 is equal to the value of the second offset modulo m, that is, second offset mod m.

[0183] Optionally, if y2 is equal to 0, the first bit of the S bits is used to indicate whether the continuous n resource blocks starting from the starting resource block in the bandwidth region BWP are used by the terminal device.

[0184] Optionally, if y2 is not equal to 0, the first bit of the S bits is used to indicate whether the m resource blocks adjacent to the continuous n resource blocks starting from the starting resource block in the bandwidth region BWP are used by the terminal device.

[0185] Optionally, if y2 is not equal to 0, the first bit of the S bits is used to indicate whether the continuous n resource blocks starting from the starting resource block in the bandwidth region BWP are used by the terminal device.

[0186] Referring to Figure 8 , the network device configures the BWP0 and the BWP1 for at least one terminal device, both of which are located in the resource blocks of the common index region, the starting position of the BWP0 is offset by 1 RB in the high frequency direction from the starting resource block of the common index region, and the offset amount of the starting position of the BWP1 is 4 RBs. In order to realize the boundary configured in the resource block unit of the starting resource block of the common index region, the first 5 RBs of the BWP0 starting from the starting resource block RB0-RB4 are taken as a resource block unit, and the RB5-RB 10 , and so on. In this way, the starting resource block RB5 of the second resource block unit in the BWP is offset by an integer multiple of 6 RBs from the starting resource block of the common index region, and the starting resource block RB 11 of the third resource block unit in the BWP0 is also offset by an integer multiple of 6 RBs from the starting resource block of the common index region. Similarly, the RB0-RB1 of the BWP1 is taken as a resource block unit. In this implementation, even if the network device configures the BWP0 and the BWP1, and possibly more BWPs, since the starting or last resource block of each resource block unit is offset by an integer multiple of m RBs from the starting resource block RB of the common index region, in the overlapping part of the multiple BWPs, it is also possible to ensure that there are as few resource fragments as possible.

[0187] Optionally, the second bit of the S bits is used to indicate whether the m resource blocks adjacent to the n resource blocks indicated by the first bit of the S bits are used by the terminal device.

[0188] Further optionally, the m resource blocks indicated by the third bit of the S bits are adjacent to the m resource blocks indicated by the second bit.

[0189] In this possible implementation, the value of S can be any of the following:

[0190] The first, The represents a floor;

[0191] The second, The represents a floor;

[0192] The third, The represents a ceiling;

[0193] The fourth, The represents a ceiling.

[0194] Through the possible implementation, a boundary of a resource block unit configured with a starting resource block of a common index region as a unit can be implemented. Such a configuration manner can implement the network device to configure resources for multiple terminal devices in a manner of aligning with the resource block unit boundary, that is, to configure resources in units of m RBs, to ensure that the resource blocks configured for the terminal device are aligned with the starting RB in units of m resource blocks on the boundary, or in other words, to ensure that the boundary of each resource block unit configured for the terminal device and the starting RB are offset by a number of RBs that is a multiple of m, so as to avoid as much as possible the occurrence of resource block fragments (fragments of less than m RBs) that cannot be allocated, and improve resource utilization efficiency. The boundary can be at least one of a low-frequency and a high-frequency boundary resource block in the resource block unit.

[0195] In the second possible implementation, the configuration of the plurality of resource blocks is aligned with a frequency domain reference point as a boundary.

[0196] In this possible implementation, a first bit in the S bits is used to indicate whether a continuous n resource blocks starting from a starting resource block in a bandwidth region BWP are used for the terminal device, or a first bit in the S bits is used to indicate whether m resource blocks adjacent to the continuous n resource blocks starting from the starting resource block in the bandwidth region BWP are used for the terminal device, a value of the n is determined according to the m and a third offset, and n is greater than 0. The explanation of the m is referred to the foregoing description and will not be repeated here.

[0197] Optionally, the n is equal to y3, or is equal to a difference between the m and y3, where a value of the y3 is equal to a value obtained by taking a modulus of the third offset with the m, and the third offset is related to the first and second offsets. Specifically, the third offset is an offset between the starting resource block of the BWP and the frequency domain reference point. Alternatively, the third offset can also be obtained according to an indication or other values corresponding to the third offset, rather than being determined according to the first and second offsets.

[0198] Further optionally, the third offset can be an offset in the number of RBs, i.e., the third offset is the number of RBs by which the starting resource block of the BWP is offset from the frequency domain reference point.

[0199] For example, when the third offset is in the low frequency direction from the frequency domain reference point, the value of n is equal to y3, or equal to m minus y3, where the value of y3 is equal to the value of the third offset modulo m, i.e., the third offset mod m. In this way, the first bit indicates y3 resource blocks from the starting resource block of the BWP, and from the (y3+1)th resource block, resource allocation is performed in units of m RBs as much as possible to achieve that the frequency domain reference point is located at the boundary of logical resource block unit allocation.

[0200] In this case:

[0201] Optionally, if y3 is not equal to 0, n is equal to y3, and the first bit of the S bits is used to indicate whether the continuous n resource blocks from the starting resource block in the bandwidth area BWP are used for the terminal device, or the first bit of the S bits is used to indicate whether the m resource blocks adjacent to the continuous n resource blocks from the starting resource block in the bandwidth area BWP are used for the terminal device.

[0202] Optionally, if y3 is equal to 0, n is equal to m minus y3, i.e., equal to m itself; and the first bit of the S bits is used to indicate whether the continuous n resource blocks from the starting resource block in the bandwidth area BWP are used for the terminal device.

[0203] For another example, when the third offset is in the high frequency direction from the frequency domain reference point, the value of n is equal to m minus y3, i.e., (m-y3), where the value of y3 is equal to the value of the third offset modulo m, i.e., the third offset mod m. In this way, the first bit indicates (m-y3) resource blocks from the starting resource block of the BWP, and the (m-y3) resource blocks can form a resource block unit of m resource blocks in quantity with the y3 RB fragments in the third offset to achieve that the frequency domain reference point is located at the boundary of logical resource block unit allocation.

[0204] In this case:

[0205] Optionally, if y3 is equal to 0, the first bit of the S bits is used to indicate whether the continuous n resource blocks from the starting resource block in the bandwidth area BWP are used for the terminal device.

[0206] Optionally, if y3 is not equal to 0, the first bit of the S bits is used to indicate whether the n contiguous resource blocks starting from the starting resource block in the bandwidth region BWP are used by the terminal device, or the first bit of the S bits is used to indicate whether the m resource blocks adjacent to the n contiguous resource blocks starting from the starting resource block in the bandwidth region BWP are used by the terminal device.

[0207] Optionally, the second bit of the S bits is used to indicate whether the m resource blocks adjacent to the n resource blocks indicated by the first bit of the S bits are used by the terminal device.

[0208] Further optionally, the third bit of the S bits indicates the m resource blocks adjacent to the m resource blocks indicated by the second bit.

[0209] In this possible implementation, the value of S can be any of the following:

[0210] Firstly, The represents the floor.

[0211] Secondly, The represents the floor.

[0212] Thirdly, The represents the ceiling.

[0213] Fourthly, The represents the ceiling.

[0214] With this possible implementation, the boundary of the resource block unit configured with the frequency domain reference point can be achieved. This configuration manner can achieve that the network device configures resources for multiple terminal devices in the manner of resource block unit boundary alignment, that is, the boundary of the resource configuration in the unit of m RBs with the frequency domain reference point as the boundary, so as to ensure that the resource blocks configured for each terminal device are aligned in the unit of m resource blocks with respect to the frequency domain reference point at the boundary, or in other words, to ensure that the number of RBs offset between the boundary of each resource block unit configured for the terminal device and the frequency domain reference point is a multiple of m, so as to avoid the appearance of resource block fragments (fragments of less than m RBs) as much as possible, and improve the resource utilization efficiency. The boundary can be at least one of the low-frequency and high-frequency boundary resource blocks of the resource block unit.

[0215] In the third possible implementation, the index information of the multiple resource blocks determined by the terminal device in step 603 is determined through offset indication information.

[0216] The method further comprises step 6023, the network device sends offset indication information to the terminal device, the terminal device acquires the offset indication information, the offset indication information is used to indicate the RB number Q of the offset of the resource indication reference resource block relative to the common index region or the BWP starting resource block, the resource indication reference resource block and the interpretation of the offset indication information are described above, which will not be repeated here.

[0217] For example, the offset RB number Q is used to indicate the continuous Q resource blocks starting from the starting resource block of the common index region or the starting resource block of the BWP; for example, the continuous Q resource blocks RB0, RB1……RB m-1 The Q is greater than or equal to 0 and less than m, the value of m is described above.

[0218] For another example, when the resource indication reference resource block is the last RB in the at least one resource block indicated by the first bit in the resource indication information, the first bit in the S bits corresponds to the continuous Q resource blocks starting from the starting resource block of the common index region or the BWP starting resource block, and the Q is not 0.

[0219] For another example, when the resource indication reference resource block is the first RB in the at least one resource block indicated by the first bit in the resource indication information, the first bit in the S bits corresponds to the continuous m resource blocks starting from the starting resource block of the common index region or the BWP, and the Q is 0.

[0220] In this optional design, the network device configures the resource block for the terminal device according to the resource block index RB index of the BWP. When the offset indication information indicates the continuous Q resource blocks starting from the starting resource block of the common index region, the terminal device determines the index information of the plurality of resource blocks through the offset indication information and the second offset.

[0221] Further optionally, the second bit of the S bits corresponds to the m resource blocks adjacent to the resource block corresponding to the first bit in the common index region or the BWP.

[0222] Optionally, the offset indication information is carried in the downlink control information DCI or the high layer signaling, and is notified to the terminal device by the network device, or is notified to the terminal device by the network device in advance and stored by the terminal device.

[0223] Further optionally, the offset indication information can be a plurality of bits, and the values indicated by the plurality of bits represent the offset RB number, as shown in Table 4.

[0224] Through the possible implementation, the network device indicates the terminal device of the starting position of the partial resource block indicated by the resource indication information while sending the terminal device of the resource indication information, so that the terminal device can efficiently acquire the resource configuration information, and the processing efficiency of the terminal device is improved.

[0225] In a third optional design, the network device configures the resource block for the terminal device according to the Common RB index.

[0226] Optionally, the method further includes the step 6021 in the first optional design, and details are referred to the foregoing description.

[0227] Optionally, the method further includes the step 6022 in the second optional design, and details are referred to the foregoing description.

[0228] Further, the terminal device further acquires the number X1 of the resource blocks of the Common index region and the number X2 of the resource blocks of the BWP, and the explanation of the X1 and the X2 is referred to the foregoing description, and the meaning is the same as the foregoing description.

[0229] In a first possible implementation, the configuration of the plurality of resource blocks is aligned with the starting resource block of the Common index region as a boundary.

[0230] In the possible implementation, the first bit of the S bits is used to indicate whether the n resource blocks starting from the starting resource block of the BWP are used for the terminal device, or the first bit of the S bits is used to indicate whether the m resource blocks adjacent to the continuous n resource blocks starting from the starting resource block in the bandwidth region BWP are used for the terminal device. The index of the starting resource block of the BWP uses the index of the resource block of the Common index region, and is determined by the index of the starting resource block of the Common index region and the second offset. The value of the n is determined according to the second offset and the m, and n>0, and the explanation of the m is referred to the foregoing description, which is not repeated here.

[0231] For example, the RB number of the Common starting resource block is 0, and the number of the starting resource block of the BWP in the Common index region is (0+second offset).

[0232] Since the frequency domain resource of the BWP is part or all of the resource blocks of the frequency domain resource of the Common index region, based on this, the second offset is the offset of the starting resource block of the BWP relative to the starting resource block of the Common index scheme in the high frequency direction.

[0233] Specifically, the value of n is equal to the difference between m and y2, and the value of y2 is equal to the value of the second offset modulo m, i.e., second offset mod m. For the optional correspondence between the value of y2 and the resource block position indicated by the first bit of the S bits, refer to the description in the first possible implementation in the second optional design.

[0234] Optionally, the second bit of the S bits is used to indicate whether the m resource blocks adjacent to the n resource blocks indicated by the first bit of the S bits are used for the terminal device.

[0235] Further optionally, the m resource blocks indicated by the third bit of the S bits are adjacent to the m resource blocks indicated by the second bit.

[0236] In this possible implementation, the value of S can be any of the following:

[0237] Firstly, The represents the floor function.

[0238] Secondly, The represents the floor function.

[0239] Secondly, The represents the ceiling function.

[0240] Thirdly, The represents the ceiling function.

[0241] Through this possible implementation, the starting resource block of the common index region can be used as the boundary of the resource block unit configuration. This configuration manner can enable the network device to configure resources for multiple terminal devices in a resource block unit boundary alignment manner, i.e., to configure resources in units of m RBs, to ensure that the resource blocks configured for the terminal device are aligned with the starting resource block in units of m resource blocks at the boundary, or in other words, to ensure that the boundary of each resource block unit configured for the terminal device and the starting RB are offset by a multiple of m RBs, thereby avoiding the occurrence of resource block fragments (fragments of less than m RBs) that cannot be allocated as much as possible, and improving the resource utilization efficiency. The boundary can be at least one of the low-frequency and high-frequency boundary resource blocks of the resource block unit.

[0242] In the second possible implementation, the configuration of the multiple resource blocks is aligned with the frequency domain reference point as the boundary.

[0243] In the possible implementation, the first bit of the S bits is used to indicate whether n resource blocks starting from a starting resource block of the BWP are used by the terminal device, or the first bit of the S bits is used to indicate whether m resource blocks adjacent to the n resource blocks starting from the starting resource block in the bandwidth region BWP are used by the terminal device. The index of the starting resource block of the BWP is the index of the resource block in the common index region, which is determined by the index of the starting resource block of the common index region and the second offset. The value of n is determined according to the m and a third offset, and n is greater than 0. The m is explained above and will not be repeated here.

[0244] For example, the RB number of the Common starting resource block is 0, and the number of the starting resource block of the BWP in the common index region is (0+second offset).

[0245] Optionally, the n is equal to y3, or is equal to the difference between m and y3, where the value of y3 is equal to the value of the third offset after the modulo operation of m, and the third offset is related to the first and second offsets. Specifically, the third offset is an offset between the starting resource block R0 of the BWP and the frequency domain reference point, which is obtained based on the first and second offsets. Alternatively, the third offset can also be obtained according to an indication or other values corresponding to the third offset, rather than being determined according to the first and second offsets.

[0246] Further optionally, the third offset can be the number of offset RBs, that is, the third offset is the number of RBs offset by the starting resource block R0 of the BWP relative to the frequency domain reference point.

[0247] For example, when the third offset is an offset of the starting resource block of the BWP relative to the frequency domain reference point in the low frequency direction, the n is equal to y3, or is equal to the value of m minus y3, where the value of y3 is equal to the value of the third offset after the modulo operation of m, that is, the third offset mod m. In this way, the first bit indicates y3 resource blocks starting from the starting resource block of the BWP, and starting from the y3+1th resource block, resource allocation is performed as much as possible in the resource block unit of m RBs, so that the frequency domain reference point is located at the boundary of the logical resource block unit allocation.

[0248] For example, when the third offset is an offset of the starting resource block of the BWP to a high frequency direction relative to the frequency domain reference point, the value of n is equal to a difference value of m minus y3, i.e., (m-y3), where the value of y3 is equal to a value of the third offset modulo m, i.e., the third offset mod m. In this way, the first bit indicates (m-y3) resource blocks starting from the starting resource block of the BWP, and the (m-y3) resource blocks can form a resource block unit of m resource blocks in quantity with the y3 RBs in the third offset to realize that the frequency domain reference point is located at the boundary of the logical resource block unit allocation.

[0249] It should be noted that the optional correspondence between the value of y3 and the resource block position indicated by the first bit of the S bits can be referred to the description in the second possible implementation of the second optional design.

[0250] Optionally, the second bit of the S bits is used to indicate whether m resource blocks adjacent to the n resource blocks indicated by the first bit of the S bits are used by the terminal device; optionally, the adjacent is adjacent in a high frequency direction.

[0251] Further optionally, the m resource blocks indicated by the third bit of the S bits are adjacent to the m resource blocks indicated by the second bit of the S bits; optionally, the adjacent is adjacent in a high frequency direction.

[0252] In this possible implementation, the value of S can be any of the following:

[0253] Firstly, The represents a floor;

[0254] Secondly, The represents a floor;

[0255] Thirdly, The represents a ceiling;

[0256] Fourthly, The represents a ceiling.

[0257] By the possible implementation, the boundary of the resource block unit configuration with the frequency domain reference point can be realized. The configuration manner can realize that the network device configures resources for multiple terminal devices in a manner of boundary alignment of the resource block unit, that is, the boundary of the resource configuration with the frequency domain reference point as the unit of m RBs, ensures that the resource blocks configured for each terminal device are aligned with the frequency domain reference point in the boundary as the resource block unit of m resource blocks, or in other words, ensures that the number of RBs offset between the boundary of each resource block unit configured for the terminal device and the frequency domain reference point is a multiple of m, and the resource block fragments (fragments of less than m RBs) that cannot be allocated are avoided as much as possible, and the resource utilization efficiency is improved. The boundary can be at least one of a low-frequency and a high-frequency boundary resource block in the resource block unit.

[0258] Embodiment 2

[0259] Embodiment 2 of the present application provides a determination method of a control resource set to realize that when multiple control resource sets overlap on time-frequency resources, the blocking probability of the control channels included in each control resource set on the resources is minimum.

[0260] Step 0: A network device determines multiple control resource sets, each of which corresponds to a mapping manner of a control channel unit;

[0261] A terminal device determines the multiple control resource sets, each of which corresponds to a mapping manner of a control channel unit.

[0262] The corresponding operation in step 0 can be performed by the processor 304 of the terminal device shown in FIG. 3 or the processor 201 of the network device shown in FIG. 2. Figure 3 Figure 2 The operation in step 1 can be performed by the processor 304 of the terminal device shown in FIG. 3.

[0263] Step 1: The terminal device detects a control channel carrying control information in the control channel resource set;

[0264] The operation in step 1 can be performed by the processor 304 of the terminal device shown in FIG. 3. Figure 3 Wherein, the control channel includes multiple control channel units (CCEs), and the control channel unit includes multiple REG bundles (REG bundles);

[0265] In an implementable manner, the control channel unit j includes a set of REG bundles {f(6j / L), f(6j / L+1),..., f(6j / L+6 / L-1)};

[0266] Wherein,

[0267]

[0268] ​​

[0269] x = cA + r

[0270] r = 0, 1,..., A - 1

[0271] c = 0, 1,..., C - 1

[0272]

[0273] or,

[0274]

[0275]

[0276] wherein:

[0277] The terminal device receives high-layer signaling from the network device, and determines the value of A according to the high-layer signaling, and the value set is {2, 3, 6};

[0278] L is the number of REGs included in the REG bundle, and optionally, L can be determined according to high-layer signaling;

[0279] is the number of resource blocks included in the control resource set in the frequency domain;

[0280] is the number of symbols included in the control resource set in the time domain;

[0281] The value of n shift may be configured by high-layer signaling, or n ID is determined according to high-layer signaling.

[0282] By this method, frequency diversity gain can be ensured when the CCE is mapped to multiple discrete REGs of the control resource set; and no matter what the value of n ID is, the CCE mapped to the control resource set can be offset in the frequency domain according to the granularity of 6 RBs, so that when multiple control resource sets overlap in time-frequency resources, the blocking probability of the control channels included in each control resource set on the resources is minimized.

[0283] Optionally, the method further includes step 2: the terminal device obtains an offset, and the offset is used for mapping of the control channel unit; the offset can be determined according to high-layer signaling, or determined according to an identifier configured by high-layer signaling.

[0284] In an implementable manner, the offset can be determined according to high-layer signaling, including: the offset n shift may be determined according to the formula determining, wherein n ID an identity configured by higher layer signaling, a number of symbols included by the control resource set in time domain; L is a number of REGs (Resource element groups) included by the REG bundle.

[0285] The method has the beneficial effect that no matter what the value of n ID is, it can ensure that the CCEs mapped to the control resource set are offset in the frequency domain in the granularity of 6 RBs, so that when multiple control resource sets overlap in time-frequency resources, the blocking probability of the control channels included by each control resource set on the resources is minimized.

[0286] The terminal device acquisition step and the step of receiving the higher layer signaling involved in the above steps can be performed by the receiver 301A of the terminal device in Figure 3 The steps of the network device sending can be performed by the transmitter 202B in Figure 2 .
