For ease of description, the above-mentioned devices are collectively referred to as terminal devices. The number of terminal devices 10 is generally multiple, and one or more terminal devices 10 may be distributed in a cell managed by each access network device 20. The terminal device may also be referred to as a terminal or UE for short, and those skilled in the art will understand its meaning.

[0035] Access network equipment 20 is a device deployed in an access network to provide wireless communication capabilities for terminal devices 10. Access network equipment 20 may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems employing different wireless access technologies, the names of devices that provide access network equipment functions may vary. For example, in 5G NR systems, they are referred to as gNodeBs or gNBs. As communication technologies evolve, the term "access network equipment" may change. For ease of description, in the embodiments of this application, the aforementioned devices that provide wireless communication capabilities for terminal devices 10 are collectively referred to as access network equipment. In some embodiments, access network equipment 20 enables communication between terminal devices 10 and core network elements 30. For example, in an LTE (Long Term Evolution) system, access network equipment 20 may be an Evolved Universal Terrestrial Radio Access Network (EUTRAN) or one or more eNodeBs within the EUTRAN. In a 5G NR system, access network equipment 20 may be a Radio Access Network (RAN) or one or more gNBs within the RAN. In the embodiment of the present application, unless otherwise specified, the "network device" refers to the access network device 20, such as a base station.

[0036] The core network element 30 is a network element deployed in the core network.

The technical solutions described in the embodiments of the present application may be applicable to LTE systems, 5G NR systems, and subsequent evolution systems of 5G NR systems (e.g., B5G (Beyond 5G) systems, 6G systems (6th Generation System, sixth generation mobile communication systems)), and other communication systems such as NB-IoT (Narrow Band Internet of Things) systems, which are not limited in this application.

[0039] In an embodiment of the present application, the network device can provide services for a cell, and the terminal device communicates with the network device through the transmission resources (for example, frequency domain resources, or spectrum resources) on the carrier used by the cell. The cell can be a cell corresponding to the network device (for example, a base station). The cell can belong to a macro base station or a base station corresponding to a small cell. The small cells here may include: metro cell, micro cell, pico cell, femto cell, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0040] Before introducing the technical solutions of this application, we first introduce and explain some of the relevant technical knowledge involved in this application. The following related technologies can be combined with the technical solutions of the embodiments of this application as optional solutions, and they all fall within the scope of protection of the embodiments of this application. The embodiments of this application include at least part of the following contents.

[0041] 1. SBFD (Subband non-overlapping Full Duplex)

[0042] To overcome the problems of weak uplink coverage, large uplink latency, and insufficient uplink capacity caused by limited uplink resource allocation in NR TDD (Time Division Duplexing), the 3GPP (3rd Generation Partnership Project) introduced XDD (cross division duplex) technology, which allows data to be sent and received simultaneously on different subbands in the same subframe / time slot / symbol. This technology is mainly used on the base station side, while the terminal side still maintains the current state, that is, only supporting sending or receiving data within a subframe / time slot / symbol. As shown in Figure 2, the middle subband of a downlink or flexible subframe / time slot / symbol is configured as an uplink subband.

[0043] The introduction of XDD technology naturally introduces two symbol types. For example, the lines above are divided into full uplink symbols, or non-SBFD (non-subband non-overlapping full-duplex) symbols, and uplink transmission resources in downlink or flexible time-domain units, or SBFD symbols. For example, in Figure 3, in the middle time slot, symbols 1-8 are SBFD symbols, with a narrower effective uplink transmission bandwidth equal to the bandwidth of the uplink subband. Symbols 9-14 are non-SBFD symbols (full uplink symbols), with a wider effective uplink transmission bandwidth equal to the bandwidth of the entire active BWP (active bandwidth part). Similarly, the distinction between symbol types can also be used to distinguish between time slot types, with some time slots being SBFD and others being non-SBFD (full uplink).

[0044] The current SBFD scheme has the following conclusions: SBFD operates within a TDD carrier. The SBFD scheme is designed within a single uplink and downlink BWP (Bandwidth Part) pair with aligned center frequencies. Within a TDD carrier, an SBFD symbol can have at most one uplink subband, which can be located in the middle or on either side of the TDD carrier.

[0045] In summary, for uplink / downlink repeated transmission, there will be a situation where multiple symbol types are spanned. To this end, two options can be set: Option 1 and Option 2. Option 1 restricts uplink transmission / downlink reception to symbols of the same type through base station configuration / scheduling. Taking PUSCH repetition (Physical Uplink Shared Channel repetition) as an example, if Option 1 is selected, PUSCH resources can only be allocated within the UL subband, which will lead to uplink resource fragmentation in all uplink symbols. Therefore, Option 2 can be considered, that is, each PUSCH transmission is restricted to one symbol type, and different PUSCH repetitions can be in different symbol types.

[0046] 2. FDRA (Frequency domain resource assignment)

[0047] NR supports two types of frequency domain resource allocation for both uplink and downlink: Type 0 frequency domain resource allocation and Type 1 frequency domain resource allocation. The network side configures the type of frequency domain resource allocation used by the terminal through the high-level parameter resourceAllocation. The terminal can be configured to use resource allocation Type 0, resource allocation Type 1, or dynamic switch. When the configuration parameter is "dynamic switch", the network side indicates the type of frequency domain resource allocation used by the terminal through the FDRA field in the DCI (Downlink Control Information).

[0048] Resource allocation Type 0:

[0049] As shown in Figure 4, the granularity of Type0 frequency domain resource allocation is RBG (Resource Block Group), which is a combination of a series of continuous virtual RBs (Resource Block). The number of virtual RBs included in each RBG is determined according to the size of the BWP (Size) and the RRC (Radio Resource Control) configuration parameter rbg-Size. rbg-Size is used to configure "configuration 1" or "configuration 2" in Table 1 below, that is, the nominal RBG size.

[0050] Table 1

[0051] As shown in Figure 4, Type0 frequency domain resource allocation uses a bitmap to indicate the RBG allocated to the terminal. 1 represents allocating this RBG to the terminal, and 0 represents not allocating this RBG to the terminal. The total number of RBGs contained in the BWP of PRBs is N RBG , is the number of the starting resource block in the BWP, and P is the nominal RBG size. exist In the case of otherwise, The remaining RBGs are of size P.

[0052] Resource Allocation Type 1:

[0053] As shown in FIG4 , Type 1 resource allocation can indicate a series of continuous virtual RBs to the terminal, using a RIV (Resource Indication Value) to indicate the start RB (RB start ) and the number of RBs (L RBs ) for joint coding.

[0054] The starting RB and the number of RBs are jointly coded as follows: In the case of otherwise in, is the size of BWP, L RBs Not less than 1 and not greater than

[0055] 3. Frequency hopping

[0056] NR supports frequency hopping for Type 1 frequency domain resource allocation of PUSCH. The basic implementation scheme is that the upper layer configures multiple frequency hopping offsets and then indicates one of them through DCI. Specifically:

[0057] Frequency hopping offsets are configured through the RRC parameter frequencyHoppingOffsetLists: when the BWP size is less than 50 PRBs, RRC configures 2 frequency hopping offsets, and the UL grant indicates one of them; when the BWP size is greater than or equal to 50 PRBs, RRC configures 4 frequency hopping offsets, and the UL grant indicates one of them.

[0058] For intra-slot frequency hopping, the starting PRB (Physical Resource Block) number is Where i=0 and i=1 correspond to the first hop and the second hop respectively.

[0059] For inter-slot frequency hopping, the starting PRB number of each hop is in It is the number of the current time slot in the system radio frame.

[0060] In the DCI FDRA indication field with frequency hopping enabled, for PUSCH frequency hopping with resource allocation type Type 1, the highest bit N of the FDRA indication field is UL_hop Used to indicate the frequency hopping offset. If the high-level parameter frequencyHoppingOffsetLists contains two offset values, then N UL_hop = 1, if the high-level parameter frequencyHoppingOffsetLists contains two offset values, then N UL_hop = 2. The bit provides frequency domain resource allocation, where The number of PRBs included in the uplink BWP.

[0061] Please refer to Figure 5, which shows a flow chart of a wireless communication method provided by an embodiment of the present application. The execution subject of each step of the method is a terminal device. The method may include step 510.

[0062] In step 510, the terminal device receives first information, where the first information includes a first indication field, and the first indication field is used to indicate frequency domain resources occupied by at least one physical channel transmission.

[0063] At least one physical channel occupies the first type of time domain resources and / or the second type of time domain resources.

[0064] In the embodiment of the present application, the time domain resource may be a subframe, a time slot, a symbol, etc., which is not limited in the present application. In some embodiments, the first information is DCI.

[0065] In some embodiments, the first information is used to schedule at least one physical channel transmission.

[0066] In some embodiments, the first indication field is an FDRA indication field in the DCI.

[0067] In some embodiments, the physical channel is a PUSCH or a PDSCH (Physical Downlink Shared Channel).

[0068] In some embodiments, the first type refers to a time domain resource type that does not include an uplink subband or a downlink subband, and the second type refers to a time domain resource type that includes an uplink subband or a downlink subband.

[0069] In some embodiments, the first type refers to a time domain resource type that does not include an uplink subband, and the second type refers to a time domain resource type that includes an uplink subband. For example, the first type of time domain resource may be a full uplink time domain resource (e.g., a non-SBFD subframe / time slot / symbol), and the second type of time domain resource may be a SBFD subframe / time slot / symbol. Accordingly, the physical channel is the PUSCH.

[0070] In some embodiments, the first type refers to a time domain resource type that does not include a downlink subband, and the second type refers to a time domain resource type that includes a downlink subband. For example, the first type of time domain resource may be a full downlink time domain resource, and the second type of time domain resource may be an SBFD subframe / time slot / symbol. Accordingly, the physical channel is a PDSCH.

[0071] In some embodiments, at least one physical channel transmission is repeated transmission of the same channel or the same TB (Transport Block). Exemplarily, at least one physical channel transmission is repeated transmission of the same PUSCH / PDSCH.

[0072] In some embodiments, at least one physical channel transmission is a single transmission of one channel or one TB. Exemplarily, at least one physical channel transmission is a single transmission of PUSCH / PDSCH.

[0073] In some embodiments, at least one physical channel transmission is separate transmission of different channels or different TBs. Exemplarily, at least one physical channel transmission is separate transmission of different PUSCHs / PDSCHs, and different PUSCHs / PDSCHs transmit different TBs.

[0074] In some embodiments, at least one physical channel transmission is a separate transmission of different parts of the same TB. For example, one TB occupies multiple time slots for transmission, and the frequency domain resources of the multiple time slots are the same.

[0075] In some embodiments, the number of bits of the first indication field is determined based on the first frequency domain bandwidth.

[0076] In some embodiments, the first frequency domain bandwidth is an activated BWP. Further, the activated BWP may be an activated uplink BWP or an activated downlink BWP.

[0077] In some embodiments, the physical channel is a PUSCH, and accordingly, the first frequency domain bandwidth is an activated uplink BWP.

[0078] In some embodiments, the physical channel is a PDSCH, and accordingly, the first frequency domain bandwidth is an activated downlink BWP.

[0079] For example, please refer to Figure 6, which shows a schematic diagram of the frequency domain resource offset corresponding to different types of time domain resources provided by an embodiment of the present application. In this example, the frequency domain resource allocation type is the frequency domain resource allocation Type0 mentioned above, the first frequency domain bandwidth is the activated UL BWP, the size of the first frequency domain bandwidth is 16 PRBs, occupying PRB1 to 16, and every two PRBs form an RBG. Then the number of bits of the first frequency domain bandwidth is equal to the number of RBGs N included in the first frequency domain bandwidth. RBG , that is, the number of bits in the first indication field is 8.

[0080] For example, please refer to Figure 7, which shows a schematic diagram of the frequency domain resource offset corresponding to different types of time domain resources provided by another embodiment of the present application. In this example, the frequency domain resource allocation type is the frequency domain resource allocation Type 1 mentioned above, the first frequency domain bandwidth is the activated UL BWP, and the size of the first frequency domain bandwidth is 16 PRBs, occupying PRB1 to 16. Then according to the formula It is determined that the number of bits of the first indication field is 8.

[0081] In some embodiments, the interpretation of the first indicator field is determined based on the first frequency domain bandwidth and / or the second frequency domain bandwidth. The interpretation of the first indicator field refers to the interpretation of the content indicated by the bits in the first indicator field. The second frequency domain bandwidth is a subset of the first frequency domain bandwidth.

[0082] In an embodiment of the present application, the interpretation of the first indication field is updated, that is, the interpretation of the first indication field can be determined according to the second frequency domain bandwidth, while the size of the first indication field is still determined according to the first frequency domain bandwidth. The function of the first indication field can be increased without increasing the size of the first indication field, thereby reducing the complexity of the terminal device in detecting the first information.

[0083] In some embodiments, the second frequency domain bandwidth is an uplink subband in an activated BWP. The uplink subband in an activated BWP can also be understood as the intersection of the activated BWP and the actually configured uplink subband. For example, when the physical channel is a PUSCH, the second frequency domain bandwidth is an uplink subband in an activated uplink BWP.

[0084] In some embodiments, the second frequency domain bandwidth is a downlink subband in an activated BWP. The downlink subband in an activated BWP can also be understood as the intersection of the activated BWP and the actually configured downlink subband. For example, when the physical channel is a PDSCH, the second frequency domain bandwidth is a downlink subband in an activated downlink BWP.

[0085] In some embodiments, the activated BWP includes two downlink sub-bands, and any one of the two downlink sub-bands, or the sum of the two, can be taken as the second frequency domain bandwidth in the embodiments of the present application.

[0086] In some embodiments, the second frequency domain bandwidth is an uplink subband and a guard bandwidth in an activated BWP.

[0087] In some embodiments, the second frequency domain bandwidth is a downlink subband and a guard bandwidth in an activated BWP.

[0088] In some embodiments, the second frequency domain bandwidth is the activated BWP minus the third frequency domain bandwidth. The third frequency domain bandwidth is the uplink subband and / or guard bandwidth in the activated BWP, or the downlink subband and / or guard bandwidth in the activated BWP.

[0089] In some embodiments, at least one physical channel occupies a first type of time domain resource. In this case, the interpretation of the first indicator field is determined according to the first frequency domain bandwidth.

[0090] In some embodiments, the lowest M bits or the highest M bits of the first indication field are used to indicate the frequency domain resources occupied by at least one physical channel in the first type of time domain resources, where M is determined based on parameters associated with the first frequency domain bandwidth, and M is a positive integer.

[0091] In some embodiments, the parameters associated with the first frequency domain bandwidth include at least one of the following: the size of the first frequency domain bandwidth, and the granularity of frequency domain resource allocation corresponding to the first frequency domain bandwidth.

[0092] In some embodiments, at least one transmission in at least one physical channel occupies the second type of time domain resources. In this case, the interpretation of the first indicator field is determined according to the second frequency domain bandwidth.

[0093] In some embodiments, the lowest N bits or the highest N bits of the first indication field are used to indicate the frequency domain resources occupied by at least one physical channel in the second type of time domain resources, where N is determined based on parameters associated with the second frequency domain bandwidth, and N is a positive integer.

[0094] In some embodiments, the parameters associated with the second frequency domain bandwidth include at least one of the following: the size of the second frequency domain bandwidth, and the granularity of frequency domain resource allocation corresponding to the second frequency domain bandwidth.

[0095] The size of the frequency domain bandwidth refers to the number of PRBs included in the frequency domain bandwidth or the number of associated RBGs. The granularity of frequency domain resource allocation refers to the smallest unit for allocating frequency domain resources. For example, for frequency domain resource allocation Type 0, the number of PRBs included in an RBG is the granularity of frequency domain resource allocation.

[0096] In some embodiments, the reference range of the frequency domain resources indicated by the least significant N bits or the most significant N bits of the first indication field is: RBGs associated with the second frequency domain bandwidth, where an RBG associated with the second frequency domain bandwidth refers to an RBG including at least X RBs belonging to the second frequency domain bandwidth, where X is a positive integer. That is, among the RBGs associated with the second frequency domain bandwidth, at least X RBs belong to the second frequency domain bandwidth. In one embodiment, X=1, that is, as long as at least one RB in an RBG belongs to the second frequency domain bandwidth range, the RBG is an RBG associated with the second frequency domain bandwidth. For example, referring to FIG6 , since PRB6 in RBG3 belongs to the second frequency domain bandwidth, RBG3 is an RBG associated with the second frequency domain bandwidth, and the PRBs included in RBG4, RBG5, and RBG6 all belong to the second frequency domain bandwidth. Therefore, in this example, the RBGs associated with the second frequency domain bandwidth are RBG3, RBG4, RBG5, and RBG6.

[0097] In some embodiments, each of the lowest N bits or the highest N bits of the first indication field corresponds to an RBG associated with the second frequency domain bandwidth. Therefore, the lowest N bits or the highest N bits of the first indication field can be used to indicate, from the RBGs associated with the second frequency domain bandwidth, the RBGs occupied by at least one physical channel in the second type of time domain resources.

[0098] In some embodiments, each codepoint of the lowest N bits or the highest N bits of the first indication field is used to indicate a distribution of frequency domain resources occupied by at least one physical channel in the second type of time domain resources in an RBG associated with the second frequency domain bandwidth. For example, if N is 2, the four codepoints 00, 01, 10, and 11 can indicate four distributions.

[0099] For example, please refer to Figure 6. In this example, the second frequency domain bandwidth is an uplink subband with a size of 7 PRBs, and the sizes of the associated RBGs in the first frequency domain bandwidth and the second frequency domain bandwidth are the same, that is, the granularity of frequency domain resource allocation in the first frequency domain bandwidth and the second frequency domain bandwidth is the same. X is 1, and the RBGs associated with the second frequency domain bandwidth are RBG3, RBG4, RBG5 and RBG6. The number of RBGs associated with the second frequency domain bandwidth can be determined as N, that is, N=4. The number of RBGs associated with the second frequency domain bandwidth can be calculated by the size of the second frequency domain bandwidth and the granularity of frequency domain resource allocation corresponding to the second frequency domain bandwidth. In this example, the number of bits in the first indication field is the same as the number of RBGs associated with the first frequency domain bandwidth, and the number of RBGs associated with the first frequency domain bandwidth can be calculated according to the formula Calculated, where is the number of PRBs included in the first frequency domain bandwidth, is the number of the starting PRB of the first frequency domain bandwidth, and P is the size of the RBG associated with the first frequency domain bandwidth. The upper 4 bits or the lower 4 bits of the 8-bit first indicator field are used to indicate the frequency domain resources occupied by at least one physical channel in the second type of time domain resources. The reference range of the frequency domain resources indicated by the upper 4 bits or the lower 4 bits of the 8-bit first indicator field is RBG3, RBG4, RBG5, and RBG6. Furthermore, if the upper 4 bits or the lower 4 bits of the 8-bit first indicator field indicate 0011, the frequency domain resources occupied by the at least one physical channel in the second type of time domain resources are RBG3 and RBG4. If the upper 4 bits or the lower 4 bits of the 8-bit first indicator field indicate 1100, the frequency domain resources occupied by the at least one physical channel in the second type of time domain resources are RBG6 and RBG5.

[0100] In some embodiments, the reference range of the frequency domain resources indicated by the least significant N bits or the most significant N bits of the first indication field is: all RBs included in the second frequency domain bandwidth.

[0101] In some embodiments, each of the least significant N bits or the most significant N bits of the first indication field is used to indicate an RB included in the second frequency domain bandwidth.

[0102] In some embodiments, each code point of the lowest N bits or the highest N bits of the first indication field is used to indicate a distribution of frequency domain resources occupied by at least one physical channel in the second type of time domain resources in the RB included in the second frequency domain bandwidth.

[0103] For example, please refer to Figure 7. In this example, the second frequency domain bandwidth is an uplink subband with a size of 7 PRBs. Then, according to the formula Determine N=5, where the size of the second frequency domain bandwidth is is 7, and the granularity of frequency domain resource allocation is 1. In this example, the upper 5 bits or lower 5 bits of the first indicator field are used to indicate the frequency domain resources occupied by at least one physical channel in the second type of time domain resources. The reference range of the frequency domain resources indicated by the upper 5 bits or lower 5 bits of the first indicator field is PRB6 to PRB12, and the SLIV coding method corresponding to the upper 5 bits or lower 5 bits of the first indicator field is the same as that described above, except that PRB6 to PRB12 contained in the uplink subband are renumbered as PRB1 to PRB7. Furthermore, the upper 5 bits or lower 5 bits of the first indicator field can indicate that the frequency domain resources occupied by at least one physical channel in the second type of time domain resources are PRB6 to PRB9.

[0104] It should be noted that in the embodiment of the present application, the frequency domain resource allocation granularity corresponding to the second frequency domain bandwidth may be the same as or different from the frequency domain resource allocation granularity corresponding to the first frequency domain bandwidth. In the case of different granularities, a finer frequency domain resource allocation granularity may be used for the second type of time domain resources. Accordingly, the terminal device needs to maintain two sets of granularity division schemes (such as two sets of RBG division schemes).

[0105] In some embodiments, the Q bits in the first indication field are used to indicate at least one of the following information: a frequency domain offset between a transmission occupying a first type of time domain resources and a transmission occupying a second type of time domain resources in at least one physical channel, a first frequency hopping offset, and a second frequency hopping offset. The Q bits are part or all of the bits in the first indication field except the lowest N bits or the highest N bits, where Q is a positive integer.

[0106] The first frequency hopping offset corresponds to a transmission occupying the first type of time domain resources in at least one physical channel. That is, the first frequency hopping offset may be a frequency domain offset between two adjacent transmissions occupying the first type of time domain resources in at least one physical channel, or may be a frequency domain offset between two hops in each transmission occupying the first type of time domain resources in at least one physical channel.

[0107] The second frequency hopping offset corresponds to a transmission in at least one physical channel that occupies the second type of time domain resources. That is, the second frequency hopping offset may be a frequency domain offset between two adjacent transmissions in at least one physical channel that occupies the second type of time domain resources, or may be a frequency domain offset between two hops in each transmission in at least one physical channel that occupies the second type of time domain resources.

[0108] In some embodiments, each code point of all or part of the Q bits may correspond to an offset value of the frequency domain offset.

[0109] In some embodiments, the frequency domain offset is an RB offset or an RBG offset.

[0110] In some embodiments, the above-mentioned RBG offset is determined based on the RBG associated with the first frequency domain bandwidth, that is, the unit of the above-mentioned frequency domain offset is the same as the frequency domain resource allocation granularity corresponding to the first frequency domain bandwidth, that is, the number of RBs included in each offset in the RBG offset is equal to the number of RBs in the RBG associated with the first frequency domain bandwidth.

[0111] In some embodiments, the above-mentioned RBG offset is determined based on the RBG associated with the second frequency domain bandwidth, that is, the unit of the above-mentioned frequency domain offset is the same as the frequency domain resource allocation granularity corresponding to the second frequency domain bandwidth, that is, the number of RBs included in each offset in the RBG offset is equal to the number of RBs in the RBG associated with the second frequency domain bandwidth.

[0112] In some embodiments, the RBG offset is determined based on the larger value of the RBG associated with the first frequency domain bandwidth and the RBG associated with the second frequency domain bandwidth. The RBG size is the number of RBs in the RBG. For example, if the RBG associated with the first frequency domain bandwidth is larger than the RBG associated with the second frequency domain bandwidth, the unit of the frequency domain offset is the same as the frequency domain resource allocation granularity corresponding to the first frequency domain bandwidth, that is, the number of RBs included in each offset in the RBG offset is equal to the number of RBs in the RBG associated with the first frequency domain bandwidth.

[0113] In some embodiments, the RBG offset is determined based on the smaller value of the RBG associated with the first frequency domain bandwidth and the RBG associated with the second frequency domain bandwidth. For example, if the RBG associated with the second frequency domain bandwidth is smaller than the RBG associated with the first frequency domain bandwidth, the unit of the frequency domain offset is the same as the frequency domain resource allocation granularity corresponding to the second frequency domain bandwidth, that is, the number of RBs included in each offset in the RBG offset is equal to the number of RBs in the RBG associated with the second frequency domain bandwidth.

[0114] In some embodiments, frequency domain resources occupied by at least one physical channel in a first type of time domain resources are determined based on frequency domain resources occupied by at least one physical channel in a second type of time domain resources.

[0115] In some embodiments, the frequency domain resources of the transmission occupying the first type of time domain resources in at least one physical channel are determined based on at least one of the following: the frequency domain resources occupied by at least one physical channel in the second type of time domain resources, the frequency domain offset between the transmission occupying the first type of time domain resources and the transmission occupying the second type of time domain resources in at least one physical channel, and the size of the first frequency domain bandwidth.

[0116] In some embodiments, the RB number of the transmission occupying the first type of time domain resources in at least one physical channel is determined according to the size of the first frequency domain bandwidth and the first intermediate value.

[0117] In some embodiments, the RB number of the transmission occupying the first type of time domain resources in at least one physical channel is obtained by performing a modulo operation on the first intermediate value and the size of the first frequency domain bandwidth.

[0118] In some embodiments, the first intermediate value is determined based on the RB number of the transmission occupying the second type of time domain resources in at least one physical channel and the above-mentioned frequency domain offset.

[0119] In some embodiments, the first intermediate value is the sum of the RB number of the transmission occupying the second type of time domain resources in at least one physical channel and the above-mentioned frequency domain offset.

[0120] In some embodiments, the RB number RB1 of the transmission occupying the first type of time domain resources in at least one physical channel is (RB2+RBoffset) mod BWPsize, where RB2 is the RB number of the transmission occupying the second type of time domain resources in at least one physical channel, RBoffset is the above-mentioned frequency domain offset, and BWPsize is the size of the first frequency domain bandwidth.

[0121] In some embodiments, the RBG number occupied by the transmission occupying the first type of time domain resources in at least one physical channel is determined according to the number of RBGs included in the first frequency domain bandwidth and the second intermediate value.

[0122] In some embodiments, the RBG number occupied by the transmission occupying the first type of time domain resources in at least one physical channel is obtained by performing a modulo operation on the second intermediate value and the number of RBGs included in the first frequency domain bandwidth.

[0123] In some embodiments, the second intermediate value is determined according to the number of RBGs occupied by transmission occupying the second type of time domain resources in at least one physical channel and the above-mentioned frequency domain offset.

[0124] In some embodiments, the second intermediate value is the sum of the number of the RBG occupied by the transmission occupying the second type of time domain resources in at least one physical channel and the frequency domain offset.

[0125] In some embodiments, the RBG number occupied by the transmission occupying the first type of time domain resources in at least one physical channel is RBG1 = (RBG2 + RBGoffset) mod BWPnum, where RBG2 is the number of the RBG occupied by the transmission occupying the second type of time domain resources in at least one physical channel, RBGoffset is the above-mentioned frequency domain offset, and BWPnum is the number of RBGs included in the first frequency domain bandwidth.

[0126] For example, please refer to Figure 6. In this example, the number of bits of the first indication field is 8, N is 4, and the RBGs occupied by the transmission occupying the second type of time domain resources in at least one physical channel are {RBG3~RBG4}. Then, all or part of the remaining 4 bits or the lower 4 bits in the first indication field, such as the upper two bits of the remaining four bits, can be used to indicate the RBG offset. For example, 00, 01, 10, and 11 represent offsets of -2 RBGs, -1 RBG, 1 RBG, and 2 RBGs, respectively. If 00 is indicated, the RBGs occupied by the transmission occupying the first type of time domain resources in at least one physical channel are {RBG3~RBG4}-2RBG, i.e., RBG1 and RBG2.

[0127] For example, please refer to Figure 7. In this example, the number of bits of the first indication field is 8, N is 5, and the RBs for transmission occupying the second type of time domain resources in at least one physical channel are {PRB6~PRB9}. Then, all or part of the remaining 5 bits or the lower 5 bits in the first indication field, such as the upper two bits of the remaining three bits, can be used to indicate the RB offset. For example, 00, 01, 10, and 11 represent offsets of -4 RBs, -2 RBs, 2 RBs, and 4 RBs, respectively. If 00 is indicated, the RBs for transmission occupying the first type of time domain resources in at least one physical channel are {PRB6~PRB9}-4PRB, that is, PRB2~PRB5.

[0128] Taking uplink transmission as an example, it can be seen that by setting the above frequency domain offset, when the second frequency domain bandwidth is an uplink subband at the middle of the uplink BWP, the frequency domain resources corresponding to the transmission of the first type of time domain resources in at least one physical channel can be offset from the middle of the uplink BWP to both sides. This ensures that the transmission of the physical channel in the second type of time domain resources falls within the range of the uplink subband, while avoiding (uplink) frequency domain resource fragmentation in the first type of time domain resources.

[0129] In the above embodiment, the first indication field is interpreted according to the size of the second frequency domain bandwidth, which can reduce the number of bits required to interpret the first indication field. The remaining bits except N bits can be interpreted for other purposes, such as indicating the above-mentioned frequency domain offset and frequency hopping offset, thereby achieving the purpose of flexibly indicating the frequency domain resources of two symbol types without increasing the overhead of the first information (such as DCI).

[0130] Frequency hopping is a relatively important means of achieving frequency diversity gain in uplink transmission. As described above, the number and size of frequency hopping offsets for different uplink transmission bandwidths are generally configured based on the uplink transmission bandwidth. The effective uplink transmission bandwidths for the first type of time domain resources and the second type of time domain resources are different. Therefore, how the configuration and indication of frequency hopping offsets are adapted to the different uplink transmission bandwidths is also a question that needs to be considered. In the above embodiment, it was mentioned that the Q bits in the first indication field can also be used to indicate the first and second frequency hopping offsets. This will be further explained in the following embodiments.

[0131] In some embodiments, R bits in the first indication field are used to indicate the first frequency hopping offset, and S bits in the first indication field are used to indicate the second frequency hopping offset, where R is a positive integer and S is a positive integer.

[0132] In some embodiments, the R bits and the S bits are non-repeating bits in the first indication field, so that different frequency hopping offset situations can be indicated more flexibly.

[0133] In some embodiments, the R bits and the S bits may be the same bits in the first indicator field, or the R bits may include S bits. In this case, no additional bits are required to indicate the two frequency hopping offsets. This is particularly applicable when the second frequency domain bandwidth is similar or identical to the first frequency domain bandwidth, for example, when the number of bits other than the N bits in the first indicator field is relatively small.

[0134] In some embodiments, T bits in the first indication field are used to indicate the first frequency hopping offset and the second frequency hopping offset, where T is a positive integer.

[0135] In some embodiments, T is determined according to the number of frequency hopping offsets included in the first frequency hopping offset list.

[0136] In some embodiments, T is determined according to the number of frequency hopping offsets included in the second frequency hopping offset list.

[0137] In some embodiments, T is determined according to the larger value of the number of frequency hopping offsets included in the first frequency hopping offset list and the number of frequency hopping offsets included in the second frequency hopping offset list.

[0138] In some embodiments, each code point of T bits may be used to indicate a frequency hopping offset in the first frequency hopping offset list and a frequency hopping offset in the second frequency hopping offset list, respectively.

[0139] For example, if the code point of T bits (T is 2) in the first indication field is 00, it can indicate the first frequency hopping offset in the first frequency hopping offset list and the first frequency hopping offset in the second frequency hopping offset list. If the code point of T bits (T is 2) in the first indication field is 01, it can indicate the second frequency hopping offset in the first frequency hopping offset list and the second frequency hopping offset in the second frequency hopping offset list.

[0140] In some embodiments, the first frequency hopping offset is determined from a first frequency hopping offset list, and the second frequency hopping offset is determined from a second frequency hopping offset list.

[0141] The first frequency hopping offset list includes at least one frequency hopping offset configured for the first type of time domain resources. Exemplarily, each code point of R bits may indicate a frequency hopping offset in the first frequency hopping offset list.

[0142] The second frequency hopping offset list includes at least one frequency hopping offset configured for the second type of time domain resources.

[0143] The frequency hopping offsets in the first and second frequency hopping offset lists can be configured directly or indirectly by the network device. For example, the network device can configure corresponding offset values ​​for the frequency hopping offsets in the first frequency hopping offset list to indicate the frequency hopping offsets in the second frequency hopping offset list. For example, if frequency hopping offset 1 and frequency hopping offset 2 in the first frequency hopping offset list are configured with offset values ​​1 and 2, respectively, then the frequency hopping offsets in the second frequency hopping offset list are frequency hopping offset 1 + offset value 1 and frequency hopping offset 2 + offset value 2. In other words, the second frequency hopping list is not directly configured but is instead obtained through the first frequency hopping list and the offset values.

[0144] For example, if the code point of T bits (T is 2) in the first indication field is 00, it can indicate the first frequency hopping offset in the first frequency hopping offset list and the first offset value in the offset value list. If the code point of T bits (T is 2) in the first indication field is 01, it can indicate the second frequency hopping offset in the first frequency hopping offset list and the second offset value in the offset value list. The offset value list includes at least one offset value configured for the frequency hopping offset in the first offset list.

[0145] Alternatively, exemplarily, in the case of T=2, when the number of frequency hopping offsets included in the first frequency hopping offset list is different from the number of frequency hopping offsets included in the second frequency hopping offset list, the frequency hopping offset is determined from the frequency hopping offset list containing a larger number of frequency hopping offsets with reference to the code points (00, 01, 10, 11) of all T bits (2 bits); and the frequency hopping offset is determined from the frequency hopping offset list containing a smaller number of frequency hopping offsets with reference to the high or low code points (1 or 0) of the T bits (2 bits).

[0146] In some embodiments, R is determined according to the number of frequency hopping offsets included in the first frequency hopping offset list.

[0147] In some embodiments, S is determined based on the number of frequency hopping offsets included in the second frequency hopping offset list. For example, each code point of S bits may indicate a frequency hopping offset in the second frequency hopping offset list. For example, if the number of frequency domain offsets included in the second frequency hopping offset list is 2, then S = 1 (code points are 0 and 1); if the number of frequency domain offsets included in the second frequency hopping offset list is 4, then S = 2 (code points are 00, 01, 10, 11).

[0148] In some embodiments, the number of frequency hopping offsets included in the second frequency hopping offset list is less than the number of frequency hopping offsets included in the first frequency hopping offset list. In this case, the S bits can be the highest S bits or the lowest S bits of the R bits, where S bits is a positive integer less than R.

[0149] In some embodiments, the number of frequency hopping offsets included in the second frequency hopping offset list is determined based on the first frequency domain bandwidth. For example, when the first frequency domain bandwidth is less than 50 PRBs, two frequency hopping offsets are configured in the second frequency hopping offset list. When the first frequency domain bandwidth is greater than 50 PRBs, four frequency hopping offsets are configured in the second frequency hopping offset list.

[0150] In some embodiments, the number of frequency hopping offsets included in the second frequency hopping offset list is determined based on the second frequency domain bandwidth. For example, when the second frequency domain bandwidth is less than 50 PRBs, two frequency hopping offsets are configured in the second frequency hopping offset list. When the second frequency domain bandwidth is greater than 50 PRBs, four frequency hopping offsets are configured in the second frequency hopping offset list.

[0151] In some embodiments, the first frequency hopping offset and the second frequency hopping offset are determined from the same frequency hopping offset list, which includes at least one frequency hopping offset. For example, the frequency hopping offset list may include four frequency hopping offsets, four of which may be used as first frequency hopping offsets and two of which may be used as second frequency hopping offsets. Therefore, S may be determined based on four, and R may be determined based on two.

[0152] For example, please refer to Figure 7. It can be seen from the above embodiment that in this example, the number of bits of the first indication field determined by the first frequency domain bandwidth is 8. Then, when frequency hopping is introduced, since the size of the first frequency domain bandwidth is 16PRB, the number of frequency hopping offsets in the first frequency hopping offset list is 2. Accordingly, the first indication field can include S=1 bits for indicating the first frequency hopping offset. Therefore, the number of bits of the first indication field can be 9, and S=1 bit can be the highest bit in the first indication field. In addition, in this example, N=5, it can be seen that there are 3 bits left in the first indication field in addition to N bits and S=1 bit. For the indication of the frequency hopping offset, one possible situation is that the upper 1 bit of the 3 bits can be used to indicate the second frequency hopping offset, and the lower 2 bits can be used to indicate the above-mentioned frequency domain offset. Another possible situation is that S=1 bit can be used to indicate the first frequency hopping offset and the second frequency hopping offset. For example, if the bit is 0, it indicates that the first frequency hopping offset is the first frequency hopping offset in the first frequency hopping offset list, and the second frequency hopping offset is the first frequency hopping offset in the second frequency hopping offset list; if the bit is 1, it indicates that the first frequency hopping offset is the second frequency hopping offset in the first frequency hopping offset list, and the second frequency hopping offset is the second frequency hopping offset in the second frequency hopping offset list.

[0153] In the above embodiment, the remaining bits except N bits in the first indication field are used to indicate two frequency hopping offsets, without increasing the number of bits of the first information, and thus reducing the complexity of terminal detection.

[0154] In some embodiments, for transmission occupying a first type of time domain resources in at least one physical channel, the starting RB is determined based on at least one of the starting RB, the first frequency hopping offset and the first frequency domain bandwidth corresponding to the frequency domain resources occupied by at least one physical channel in the first type of time domain resources.

[0155] It can be seen from the above embodiments that the frequency domain resources occupied by at least one physical channel in the first type of time domain resources can be determined based on the frequency domain resources occupied by at least one physical channel in the second type of time domain resources. Accordingly, the starting RB corresponding to the frequency domain resources occupied by at least one physical channel in the first type of time domain resources can also be determined based on the starting RB corresponding to the frequency domain resources occupied by at least one physical channel in the second type of time domain resources. Specifically, the starting RB number RB corresponding to the frequency domain resources occupied by at least one physical channel in the first type of time domain resources is start-1 =(RB start-2 +RBoffset)mod BWPsize, where RB start-2is the starting RB number corresponding to the frequency domain resources occupied by at least one physical channel in the second type of time domain resources, RBoffset is the above-mentioned frequency domain offset, and BWPsize is the size of the first frequency domain bandwidth.

[0156] In some embodiments, when a transmission occupying a first type of time domain resource in at least one physical channel frequency hops within a time slot, for the first hop of each transmission occupying the first type of time domain resource in the at least one physical channel, the number of the starting RB is determined based on the number of the starting RB corresponding to the frequency domain resource occupied by the at least one physical channel in the first type of time domain resource. Specifically, the number of the starting RB is equal to the number of the starting RB corresponding to the frequency domain resource occupied by the at least one physical channel in the first type of time domain resource. For the second hop of each transmission occupying the first type of time domain resource in the at least one physical channel, the number of the starting RB is determined based on the number of the starting RB corresponding to the frequency domain resource occupied by the at least one physical channel in the first type of time domain resource, the first frequency hopping offset, and the first frequency domain bandwidth. Specifically, the number of the starting RB is obtained by performing a modulo operation on a third intermediate value and the first frequency domain bandwidth. The third intermediate value may be the sum of the number of the starting RB corresponding to the frequency domain resource occupied by the at least one physical channel in the first type of time domain resource and the first frequency hopping offset.

[0157] Exemplarily, in the case where the transmission occupying the first type of time domain resources in at least one physical channel is frequency-hopped within a time slot, Among them, RB start1 It is the number of the starting RB of a certain hop in a transmission of at least one physical channel occupying the first type of time domain resources. offset-1 is the first frequency hopping offset, BWP size is the size of the first frequency domain bandwidth (activated BWP), and i=0 and i=1 respectively indicate the first hop and the second hop in one transmission.

[0158] In some embodiments, when a transmission occupying a first type of time domain resource on at least one physical channel frequency hops between time slots, for a transmission in a time slot that meets the first determination value of 0, the number of the starting RB is determined based on the number of the starting RB corresponding to the frequency domain resource occupied by the at least one physical channel in the first type of time domain resource. Specifically, the number of the starting RB is equal to the number of the starting RB corresponding to the frequency domain resource occupied by the at least one physical channel in the first type of time domain resource. For a transmission in a time slot that meets the first determination value of 1, the number of the starting RB is determined based on the number of the starting RB corresponding to the frequency domain resource occupied by the at least one physical channel in the first type of time domain resource, the first frequency hopping offset, and the first frequency domain bandwidth. Specifically, the number of the starting RB is obtained by performing a modulo operation on the third intermediate value and the first frequency domain bandwidth. The first determination value can be determined based on the number of the time slot in which the transmission occurs. Specifically, the first determination value can be obtained by performing a modulo operation on the number of the time slot in which the transmission occurs and 2.

[0159] Exemplarily, in the case where the transmission occupying the first type of time domain resources in at least one physical channel hops between time slots, Among them, RB start2 It is the number of the starting RB of transmission in a certain time slot in transmission occupying the first type of time domain resources in at least one physical channel. is the first judgment value, is the number of one of the above time slots.

[0160] In some embodiments, for transmissions occupying a second type of time domain resources in at least one physical channel, the starting RB is determined based on at least one of the starting RB corresponding to the frequency domain resources occupied by at least one physical channel in the second type of time domain resources, the second frequency hopping offset, and the second frequency domain bandwidth.

[0161] As can be seen from the above embodiment, the lowest N bits or the highest N bits of the first indication field are used to indicate the frequency domain resources occupied by at least one physical channel in the second type of time domain resources. In other words, the lowest N bits or the highest N bits of the first indication field can directly indicate the starting RB corresponding to the frequency domain resources occupied by at least one physical channel in the second type of time domain resources.

[0162] In some embodiments, when a transmission occupying a second type of time domain resource in at least one physical channel frequency hops within a time slot, for the first hop of each transmission occupying the second type of time domain resource in the at least one physical channel, the number of the starting RB is determined based on the number of the starting RB corresponding to the frequency domain resource occupied by the at least one physical channel in the second type of time domain resource. Specifically, the number of the starting RB is equal to the number of the starting RB corresponding to the frequency domain resource occupied by the at least one physical channel in the second type of time domain resource. For the second hop of each transmission occupying the second type of time domain resource in the at least one physical channel, the number of the starting RB is determined based on the number of the starting RB corresponding to the frequency domain resource occupied by the at least one physical channel in the second type of time domain resource, the second frequency hopping offset, and the second frequency domain bandwidth. Specifically, the number of the starting RB is obtained by performing a modulo operation on a fourth intermediate value and the second frequency domain bandwidth. The fourth intermediate value may be the sum of the number of the starting RB corresponding to the frequency domain resource occupied by the at least one physical channel in the second type of time domain resource and the first frequency hopping offset.

[0163] Exemplarily, when the transmission occupying the second type of time domain resources in at least one physical channel is frequency-hopped within a time slot, Among them, RB start3 It is the number of the starting RB of a certain hop in a transmission of at least one physical channel occupying the second type of time domain resources. offset-2 is the second frequency hopping offset, UL subband size is the size of the second frequency domain bandwidth (uplink subband), i=0 and i=1 respectively indicate the first hop and the second hop in each transmission.

[0164] In some embodiments, when a transmission occupying a second type of time domain resource in at least one physical channel hops between time slots, then for a transmission occupying the second type of time domain resource in at least one physical channel, where the time slot meets the first determination value of 0, the number of the starting RB is determined according to the number of the starting RB corresponding to the frequency domain resource occupied by the at least one physical channel in the second type of time domain resource. Specifically, the number of the starting RB is equal to the number of the starting RB corresponding to the frequency domain resource occupied by the at least one physical channel in the second type of time domain resource. For a transmission occupying the second type of time domain resource in at least one physical channel, where the time slot meets the first determination value of 1, the number of the starting RB is determined according to the number of the starting RB corresponding to the frequency domain resource occupied by the at least one physical channel in the second type of time domain resource, the second frequency hopping offset, and the first frequency domain bandwidth. Specifically, the number of the starting RB is obtained by performing a modulo operation on the fourth intermediate value and the second frequency domain bandwidth.

[0165] Exemplarily, in the case where the transmission occupying the second type of time domain resources in at least one physical channel hops between time slots, Among them, RB start4 is the number of the starting RB of transmission in a certain time slot in the transmission occupying the second type of time domain resources in at least one physical channel, is the number of one of the above time slots.

[0166] It should be noted that the above formulas in pairs can be split and combined arbitrarily by technicians according to their needs, and this application does not limit this.

[0167] The technical solution provided by the embodiment of the present application is achieved by receiving the first information by the terminal device, and the first indication field in the first information is used to indicate the frequency domain resources occupied by the transmission of at least one physical channel, and at least one physical channel occupies the first type of time domain resources and / or the second type of time domain resources. It is realized that the frequency domain resources occupied by the transmission of at least one physical channel are indicated through the first information. Furthermore, in the case where at least one physical channel occupies the first type and the second type of time domain resources, the above method can indicate the frequency domain resources occupied by the physical channel transmission in two different types of time domain resources through one indication information (i.e., the first information).

[0168] Please refer to Figure 8, which shows a flow chart of a wireless communication method provided by an embodiment of the present application. The execution subject of each step of the method is a network device. The method may include step 810.

[0169] In step 810 , the network device sends first information, where the first information includes a first indication field, and the first indication field is used to indicate frequency domain resources occupied by at least one physical channel transmission.

[0170] At least one physical channel occupies the first type of time domain resources and / or the second type of time domain resources.

[0171] In some embodiments, the first type refers to a time domain resource type that does not include an uplink subband or a downlink subband, and the second type refers to a time domain resource type that includes an uplink subband or a downlink subband.

[0172] In some embodiments, the number of bits of the first indication field is determined based on the first frequency domain bandwidth.

[0173] In some embodiments, the lowest N bits or the highest N bits of the first indication field are used to indicate the frequency domain resources occupied by at least one physical channel in the second type of time domain resources, where N is determined based on parameters associated with the second frequency domain bandwidth, which is a subset of the first frequency domain bandwidth, and N is a positive integer.

[0174] In some embodiments, there is at least one transmission in at least one physical channel occupying the second type of time domain resources.

[0175] In some embodiments, the parameters associated with the second frequency domain bandwidth include at least one of the following: the size of the second frequency domain bandwidth, and the granularity of frequency domain resource allocation corresponding to the second frequency domain bandwidth.

[0176] In some embodiments, frequency domain resources occupied by at least one physical channel in a first type of time domain resources are determined based on frequency domain resources occupied by at least one physical channel in a second type of time domain resources.

[0177] In some embodiments, the reference range of the frequency domain resources indicated by the lowest N bits or the highest N bits of the first indication field is: RBGs associated with the second frequency domain bandwidth, where the RBGs associated with the second frequency domain bandwidth refer to RBGs including at least X RBs belonging to the second frequency domain bandwidth, where X is a positive integer. Alternatively, all RBs included in the second frequency domain bandwidth.

[0178] In some embodiments, the Q bits in the first indication field are used to indicate at least one of the following information: a frequency domain offset, a first frequency hopping offset, and a second frequency hopping offset between transmissions occupying the first type of time domain resources and transmissions occupying the second type of time domain resources in at least one physical channel.

[0179] The first frequency hopping offset corresponds to transmissions in at least one physical channel occupying time domain resources of a first type.

[0180] The second frequency hopping offset corresponds to transmissions in the at least one physical channel occupying time domain resources of a second type.

[0181] The Q bits are part or all of the bits in the first indication field except the least significant N bits or the most significant N bits, where Q is a positive integer.

[0182] In some embodiments, the frequency domain offset is an RB offset or an RBG offset.

[0183] In some embodiments, the RBG offset is determined based on the RBG associated with the first frequency domain bandwidth. Alternatively, the RBG offset is determined based on the RBG associated with the second frequency domain bandwidth.
