Description

[0001] This application is a divisional application of the application for patent with application number 201911101906.1, the application date of which is November 12, 2019, and the title of which is "Resource Determination Method and Device". TECHNICAL FIELD

[0002] The present application relates to the technical field of wireless communication, in particular, the present application relates to a resource determination method and device. BACKGROUND

[0003] The NR (New Radio) system mostly uses a higher frequency point than the LTE (Long Term Evolution) system. However, since the deployment cost of a base station is very high, the operator system can achieve a coverage performance comparable to the LTE system by using the NR system, so that the NR base station device can be directly upgraded or deployed on the original LTE site.

[0004] In the NR system, one transmission (or repetition) of one transport block (TB) occupies all or part of the symbols in a time slot in time and occupies one or more physical resource blocks (PRBs) in the frequency domain. However, since the uplink is a power-limited system, even if more PRBs are allocated, the coverage enhancement effect cannot be achieved. On the contrary, the transmission time of the uplink should be as long as possible. Although the NR currently supports repeated transmission, since the current time domain resource scheduling of the NR is at most in units of a time slot, when the number of PRBs occupied in the frequency domain is small, the TB cannot be transmitted across multiple time slots. Compared with transmitting a TB across multiple time slots by using a lower code rate, although the current system supports the method of using redundancy version (RV) rotation to improve performance, when the code rate is too high, the performance is still limited.

[0005] In addition, for higher frequency transmission, such as >52.6GHz, a larger subcarrier spacing, such as several hundred kHz, needs to be used. Then, the time of a time slot will be very short. In this way, in order to meet the uplink coverage requirement, a longer transmission time is needed. Therefore, how to more effectively indicate the time domain and frequency domain resource allocation is a problem to be solved. SUMMARY

The embodiments described below are examples of how the present application can be implemented, and are not to be construed as limiting the present application.

In addition, "connected" or "coupled" used herein can include wireless connection or wireless coupling. The phrase "and / or" used herein includes all or any one of the associated listed items and all combinations thereof.

[0030] In order to better understand and illustrate the scheme of the embodiments of the present application, some technologies involved in the embodiments of the present application are briefly described below.

[0031] Figure 1An example of a wireless communication system 100 is shown, in which the wireless communication system 100 comprises one or more fixed infrastructure units forming a network distributed over a geographical area. The infrastructure units can comprise APs (Access Points), ATs (Access Terminals), BSs (Base Stations), Node-Bs, eNBs (evolved Node Bs), gNBs (next generation Node Bs) and other terminology used in the art.

[0032] As shown in Figure 1 Infrastructure units 101 and 102 serve a number of MSs (mobile stations) or UEs or terminal devices or users 103 and 104 in a service area, which can be a cell or a cell sector. In some systems, one or more BSs can be communicably coupled to a controller forming an access network, which can be communicably coupled to one or more core networks. The present example is not limited to any particular wireless communication system.

[0033] In the time and / or frequency domain, infrastructure units 101 and 102 transmit DL (Downlink) communication signals 112 and 113, respectively, to MSs or UEs 103 and 104. MSs or UEs 103 and 104 communicate with infrastructure units 101 and 102, respectively, through UL (Uplink) communication signals 111 and 114.

[0034] Optionally, the mobile communication system 100 is an OFDM (Orthogonal Frequency Division Multiplexing) / OFDMA (Orthogonal Frequency Division Multiple Access) system comprising a plurality of base stations including base station 101, base station 102, and a plurality of UEs including UE 103 and UE 104. Base station 101 communicates with UE 103 through UL communication signals 111 and DL communication signals 112.

[0035] When a base station has downlink packets to send to a UE, each UE gets a downlink assignment (resources), such as a set of radio resources in a PDSCH (Physical Downlink Shared Channel). When a UE needs to send a packet in the uplink to the base station, the UE gets a grant from the base station, where the grant allocates a set of uplink radio resources in a PUSCH (Physical Uplink Shared Channel). The UE gets the downlink or uplink scheduling information from a PDCCH (Physical Downlink Control Channel) dedicated to itself. The downlink or uplink scheduling information and other control information carried by the PDCCH is called DCI (Downlink Control Information).

[0036] Figure 1Different physical channels of the downlink 112 and the uplink 111 examples are also shown. The downlink 112 includes a PDCCH 121, a PDSCH 122, a PBCH (Physical Broadcast Channel) 123, and a PSS (Primary Synchronization Signal) / SSS (Secondary Synchronization Signal or Secondary Synchronization Signal) 124. Among them, in 5G NR, the PSS, the SSS, and the PBCH jointly constitute an SSB (SS / PBCH block) 125. The PDCCH 121 transmits a DCI 120 to the UE, that is, the DCI 120 is carried by the PDCCH 121. The PDSCH 122 transmits downlink data information to the UE. The PBCH carries an MIB (Master Information Block), which is used for early discovery of the UE and cell-wide coverage. The uplink 111 includes a PUCCH (Physical Uplink Control Channel) 131 carrying a UCI (Uplink Control Information) 130, a PUSCH 132 carrying uplink data information, and a PRACH (Physical Random Access Channel) 133 carrying random access information. In addition to the traditional cellular networking mode, the application can also be applied to the resource allocation method of sidelink transmission. Sidelink transmission refers to communication between terminals.

[0037] Optionally, the wireless communication network 100 uses OFDMA or a multi-carrier architecture, including AMC (Adaptive Modulation and Coding) on the downlink and a next-generation single-carrier FDMA architecture or a multi-carrier OFDMA architecture for UL transmission. The FDMA single-carrier architecture includes IFDMA (Interleaved FDMA), LFDMA (Localized FDMA), DFT-SOFDM (DFT-spread OFDM) of IFDMA or LFDMA. In addition, various enhanced NOMA (non-orthogonal multiple access) architectures of the OFDMA system are also included.

[0038] An OFDMA system serves remote units by allocating downlink or uplink wireless resources that typically include a set of subcarriers over one or more OFDM symbols. Example OFDMA protocols include the evolving LTE and 5G NR in the 3GPP UMTS standards, and the IEEE 802.16 family of standards in the IEEE standards. The architecture can also include the use of transmission techniques such as MC-CDMA (multi-carrier CDMA), MC-DS-CDMA (multi-carrier direct sequence CDMA), OFCDM (Orthogonal Frequency and Code Division Multiplexing, one or two dimensional transmission of orthogonal frequency code division multiplexing). Alternatively, simpler time and / or frequency division multiplexing / multiple access techniques, or combinations of these different techniques, can be employed. In an alternative embodiment, the communication system can use other cellular communication system protocols, including but not limited to TDMA (Time division multiple access) or direct sequence CDMA (Code Division Multiple Access).

[0039] In NR system, the minimum unit of frequency domain resource allocation is one PRB. In order to reduce the overhead of frequency domain resource allocation, NR follows the concept of resource block group (RBG) in LTE, and the RBG size is determined according to the base station configuration and the bandwidth of BWP (bandwidth Part). In the frequency domain, one transport block (TB) occupies at most 14 symbols in a slot, which is indicated in the time domain resource allocation (TDRA) in the downlink control information DCI. Before establishing the RRC (Radio Resource Control) link, the TDRA table is defined in the protocol in advance, which includes: the parameter K0 (for PDSCH) or K2 (for PUSCH) for indicating the slot position, the starting position S of the symbol in the slot and the symbol length L, and the data transmission mapping type (the type of DMRS mapping Type A and Type B). For the downlink data channel PDSCH, the indication of the DMRS position is also included in the pre-defined TDRA table. After establishing the RRC, the base station can configure a new TDRA table for the UE through the RRC to indicate the time domain resource allocation information. In order to reduce the signaling overhead, the start and length indicator (SLIV) indicating the starting symbol S and the length L is used to indicate the starting position S of the symbol in the slot and the symbol length L.

[0040] The physical uplink shared channel (PUSCH) is taken as an example for illustration, and the same method is applicable to the physical downlink shared channel (PDSCH).

[0041]

[0042] The slot in which the UE transmits the PUSCH is determined by K2 as .

[0043] Wherein, n is the slot in which the scheduling DCI is located, K2 is determined based on the numerology of the PUSCH, and and Subcarrier spacing of PUSCH and PDCCH respectively. The starting symbol S allocated to PUSCH relative to the starting slot, and the number of consecutive symbols L calculated from symbol S by the following formula (1) and formula (2) and the indication of the starting and length (SLIV) of the corresponding row according to the index decide: If Then (Formula 1), Else (Formula 2), Where .

[0044] The mapping type of PUSCH according to the row of the index is set based on the Type A and Type B PUSCH mapping defined in section 6.4.1.1.3 of the protocol TS 38.211. The configuration method of the TDRA table of PDSCH and the TDRA table of PUSCH is similar.

[0045] In NB-IoT system, in order to support coverage enhancement, the concept of resource block (RU) is defined, so that one transmission of a TB can span multiple subframes. In NB-IoT, the number of resource elements (RE) contained in one RU is the same. The length of RU is calculated by indicating the number of carriers occupied by each RU, in addition, the length of the corresponding transport block (TB) size is calculated by indicating the number of RUs.

[0046] For OFDM communication system with large subcarrier spacing (such as subcarrier spacing of 120 kHz or 240 kHz) and / or system requiring coverage enhancement, especially system requiring uplink coverage enhancement, one transport block also needs to be on multiple time domain resource units (such as time unit on slot, subframe, one or several symbol time domains, etc.). Compared with the method of multiple repetitions or multiple transmissions, it can provide lower code rate, thereby obtaining better performance, especially when the transmission bandwidth is limited.

[0047] For the TDRA table configured by RRC, the starting symbol S and the symbol length L are calculated according to the value of SLIV in the TDRA table and formula (1); or the value of SLIV is calculated according to S and L, and SLIV is indicated in the TDRA table, or the starting symbol S and the symbol length L are directly indicated in the TDRA table.

[0048] For the purpose, technical solutions and advantages of the present application, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0062] Optionally, according to the resource allocation information, the granularity of at least one time domain sub-block is determined, including: According to the subcarrier spacing in the resource allocation information, and a pre-defined or base station configured correspondence between the subcarrier spacing and the granularity of the time domain sub-block, the granularity of at least one time domain sub-block is determined. Alternatively, according to the granularity of a frequency domain resource sub-block in the resource allocation information, and a pre-defined or base station configured correspondence between the granularity of the frequency domain resource sub-block and the granularity of the sub-block, the granularity of at least one time domain sub-block is determined.

[0063] Optionally, according to the resource allocation information, the manner of determining the number of subcarriers in at least one sub-physical resource block includes at least one of the following: According to the information for indicating the number of subcarriers in at least one sub-physical resource block in the resource allocation information, the number of subcarriers in at least one sub-physical resource block is determined. According to the information for indicating the size of a bandwidth block (BWP) block size or the size of a bandwidth occupied by a BWP in the resource allocation information, the number of subcarriers in at least one sub-physical resource block is determined. According to the information for indicating the subcarrier spacing in the resource allocation information and the information of the bandwidth of at least one sub-physical resource block, the number of subcarriers in one sub-physical resource block is determined.

[0065] Another method for resource allocation is provided in the embodiments of the present application, and is applied to a base station. A flowchart of the method is shown in FIG. 2. The method comprises the following steps. Figure 3 In step S201, resource allocation information is sent.

[0066] In step S202, a time domain resource position occupied by one transmission block (TB) in one transmission and / or a total symbol length occupied by one TB in one transmission is determined according to the resource allocation information. One TB occupies multiple time units in one transmission; and / or, A number of subcarriers in at least one sub-physical resource block is determined according to the resource allocation information, and a frequency domain resource position occupied by the one TB is determined according to the number of subcarriers in the at least one sub-physical resource block, wherein the number of subcarriers in the at least one sub-physical resource block is less than the number of subcarriers in one physical resource block.

[0067] In the embodiments of the present application, more efficient resource allocation for TB transmission is achieved.

[0068] The above embodiments of the present application are fully and thoroughly introduced through the following embodiments. The method of the present application is applicable to a downlink channel, an uplink channel or a sidelink channel.

[0069] In a first aspect, in order to support the transmission of one TB in multiple time units, several time domain resource allocation methods are introduced as follows.

[0070] Method one: A TDRA table indicates a starting symbol position S on a first time unit, a symbol length on a last time unit, and a number n of time units.

[0071] Optionally, a new parameter n is added in each row of the TDRA table to determine a resource position, wherein n is used to indicate the number of time units occupied by one TB. In another example, the new parameter n can be indicated by additional signaling, wherein the additional signaling includes one or more of the following joint indications: RRC, MAC, DCI. In the first method, the DCI overhead for indicating the TDRA can be saved, and in the second method, the RRC configuration overhead of the TDRA table can be reduced. The UE determines a starting slot position according to a parameter K0 or K2 in the TDRA table for indicating the slot position, and determines a starting symbol position according to a symbol starting position S in the TDRA table. The UE determines the number of slots occupied by the TB according to the number n of time units in the TDRA table, and determines the number of symbols L occupied in the last slot according to a symbol length L in the TDRA table. The number n of time units can be defined or configured as one of the following: ​(A) The number of time units n includes the total number of time units occupied by the starting time unit, the time units other than the time units occupied by the starting position and the ending position, and the ending time unit. (B) The number of time units n includes the number of time units other than the time units occupied by the starting and ending positions. (C) The number of time units n includes the number of time units occupied by the complete time units.

[0072] Specifically, if S = 0 or L is the number of symbols in a time unit, then it is included, otherwise it is not included.

[0073] Optionally, the time unit can be predefined as several symbols, such as 14 symbols. At this time, a time unit is a slot in an NR system. However, an actual one-time transmission of a TB can occupy part of the symbols in a slot.

[0074] Optionally, the UE calculates the total number of symbols L_all occupied by the one-time transmission of the TB according to at least one of the following: the parameter n used to indicate the number of time units occupied by one TB, the starting symbol S, the symbol length L, and the number of symbols in each time unit l _unit. The UE calculates the transport block size (TBS) according to the L_all. Specifically, for the above method (A), .

[0075] Optionally, Table 1 is an example of a table for PUSCH resource allocation. For an RRC configured TDRA table, the starting symbol S and the symbol length L are obtained by indicating SLIV and according to formula (1). The UE obtains the TDRA index number used to indicate the time domain resource allocation according to the DCI or the RRC (for example, for the uplink configured grant type one (configured grant type 1)). The index is indicated as index 1 in Table 1. Then, as shown in Figure 4 , the UE obtains the time domain resource configuration as: starting from the 3rd symbol (symbol 2) of the jth slot after the slot in which the PDCCH is received, to the 8th symbol (symbol 7) position of the j+3th slot. Wherein, the subcarrier spacing of the PUSCH is 15 kHz, according to the predefined rule, j = 1.

[0076] At this time, l _unit = 14, then the total number of symbols occupied by the transmission is .

[0077] Table 1: TDRA table

[0078] Method two: according to the starting position of the sub-block indicated by SLIV (or the starting symbol S and the symbol length L indicated in the TDRA table) and the number n of sub-blocks, the position of the time domain resource allocation is determined. Wherein, the number n of sub-blocks can be added in a new column in the TDRA table (a new parameter is added in each index), or can be additionally indicated by signaling. Wherein, the additional signaling includes one or more of the following joint indications: RRC, MAC, DCI.

[0079] Optionally, one sub-block is defined as L symbols. The number of symbols in one sub-block can be less than or equal to the number of symbols in one time unit.

[0080] SLIV represents the starting position and symbol length of the first sub-block in a time unit. According to SLIV, the starting position and symbol length of the first sub-block in a time unit can be determined. In addition, the end position can also be determined according to the starting position and symbol length of the first sub-block in a time unit. Wherein, the end position can be within the first time unit, or within other time units, i.e. more time units. In addition, the time domain positions of other sub-blocks can be inferred according to the predefined rules. Specifically, one of the following methods can be implemented: Method A: In the next n time units, each sub-block occupies the same symbol allocation.

[0081] Optionally, taking Table 1 index 1 as an example, S = 2, L = 8, n = 4. As shown in the following figure, the TB transmission starts from the 3rd symbol (symbol 2) in slot j for 8 consecutive symbols, and in slot j+1, slot j+2, slot j+3, it also starts from the 3rd symbol (symbol 2) for 8 consecutive symbols. Figure 5

[0082] Method B: According to SLIV (or the starting symbol S and the symbol length L indicated in the TDRA table), the symbol allocation occupied by the first sub-block is determined, and the next n symbols available for uplink or downlink data transmission are occupied in succession, i.e. n symbols with length L are occupied in turn.

[0083] Optionally, taking Table 1 index 1 as an example, S = 2, L = 8, n = 4. As shown in the following figure, the TB transmission starts from the 3rd symbol (symbol 2) in slot j for 8 consecutive symbols, and on the next n-1 sub-blocks. Wherein, each sub-block includes 8 symbols. Figure 6 Figure 6 ​​As shown, the second sub-block occupies symbols 10 to 13 in time slot j and symbols 0 to 3 in time slot j+1, the third sub-block occupies symbols 4 to 11 in time slot j+1, and the fourth sub-block occupies symbols 12 to 13 in time slot j+1 and symbols 0 to 5 in time slot j+2.

[0084] Optionally, the UE calculates the total symbol length L_all occupied by the TB in one transmission based on at least one of the following: the parameter n used to indicate the number of sub-blocks occupied by a TB, the number of symbols L in each sub-block, and the total number of symbols used to transmit the TB. The UE calculates the transport block size (TBS) based on this L_all.

[0085] For index 1 in Table 1 above, it can be calculated that... .

[0086] Method 3: The TDRA table indicates the time unit position K, the starting symbol position S in the starting time unit, and the total symbol length L_all. L_all can be greater than the number of symbols in a time unit (such as a time slot or subframe). In this method, a time unit can be a time slot.

[0087] There are two specific methods to indicate S and L_all: Method X: Configure the TDRA table via RRC, where the starting symbol position and the total symbol length L_all are configured respectively.

[0088] Alternatively, configuring S and the total symbol length L_all separately is simpler and more direct. There's no need to introduce additional SLIV calculations to support approximately the number of symbols in one time unit. For example, in Table 1, the starting symbol S position corresponding to index 3 is 2, and the total symbol length L_all = 28. Here, one time slot unit contains 14 symbols, and the total symbol length is approximately the number of symbols in one time unit.

[0089] Method Y: Jointly encode the starting symbol position S and the total symbol length L_all and indicate them in the TDRA table.

[0090] Optionally, if the indication of the start symbol position S is within a time unit (such as a slot or subframe), then the position of the first time unit occupied by a TB transmission can be additionally indicated in the TDRA table, for example, K0 for PDSCH to indicate the start slot and K2 for PUSCH to indicate the start slot. In one example, if the number of symbols in a slot is 14, and If S < 14, then SLIV can be calculated using the following method:

[0091]

[0092] In Method 3, the total number of symbols used in a single transmission is L_all, which is determined directly by TDRA or calculated based on SLIV in TDRA.

[0093] Optionally, in the first three methods, the time unit can be a time slot, and the number of symbols in a sub-block is usually less than or equal to the number of symbols in a time unit. To reduce overhead, the number of symbols in a sub-block can be greater than the number of symbols in a time unit (such as a time slot). In method four, described below, the base station can configure several numbers of symbols and / or time slots as a new sub-block, and then use the sub-block to replace the symbols as the smallest unit of time-domain scheduling resources.

[0094] Method 4: The UE obtains the granularity of at least one sub-block based on the base station configuration; it determines the time-domain resource location of a TB based on the starting resource location S in the time-domain resource indication field indicated by the base station and the number of sub-blocks n. Specific implementation methods include the following: Method 1: The UE obtains a sub-block with a granularity of L1 symbols or L1 time units (such as time slots) based on the base station configuration. The starting resource location S indicates the location at which the transmission begins.

[0095] Optionally, such as Figure 7 As shown, the base station configures a sub-block granularity L1 of 2 symbols. Then S=2 and n=8 represent that a transmission of TB starts from the 3rd sub-block and occupies 8 sub-blocks. That is, it occupies symbols 4 to 13 in time slot j and symbols 0 to 5 in time slot j+1.

[0096] The total symbol length for a single TB transmission is calculated based on the number of symbols in a sub-block and the number of sub-blocks. When L1 represents the number of symbols, the total number of symbols is... When L1 represents the number of time slots, assuming one time slot has 14 symbols, then the number of symbols is... .

[0097] Method 2: The UE obtains a sub-block 1 of size L1 symbols or L1 time units (such as time slots) to determine the starting position, and a sub-block 2 of size L2 symbols or L1 time units (such as time slots) to determine the transmission length, based on the base station configuration. The starting resource position S indicates the position of the first sub-block 1 transmission. The actual number of symbols transmitted is determined by the size L2 of sub-block 2.

[0098] Optionally, such as Figure 8As shown, the base station is configured with a sub-block size L1 of 2 symbols to indicate the starting position, and a sub-block size L2 of 8 symbols to indicate the symbol length. Therefore, S=2 and n=4 represent that a transmission of one TB starts from the third sub-block of length 2 symbols and occupies 4 sub-blocks of length 8 symbols. That is, it occupies symbols 4 to 13 in time slot j, all symbols in time slot j+1, and symbols 0 to 7 in time slot j+2.

[0099] The total symbol length required for a single TB transmission is calculated based on the number of symbols L2 in a sub-block and the number of sub-blocks n. When L2 is the number of symbols, the total number of symbols is... When L2 represents the number of time slots, assuming one time slot has 14 symbols, then the number of symbols is... .

[0100] Compared to Method 1, Method 2 can indicate a more flexible starting position.

[0101] Optionally, for methods 1 and 2 above, time slot j can be determined according to the time slot position determination method in the preceding methods (e.g., according to K0 or K2 in the TDRA table). Alternatively, time slot j can be predefined as either the time slot occupied by the corresponding PDCCH transmission or the position of the xth time slot after the corresponding PDCCH transmission. Preferably, time slot j being the time slot occupied by the corresponding PDCCH transmission is more suitable for PDSCH indication, while the position of the xth time slot after the corresponding PDCCH transmission is more suitable for PUSCH indication. Here, x can be determined based on the UE's processing capacity and / or subcarrier spacing.

[0102] Alternatively, for methods 1 and 2 above, S and n can also be jointly encoded. In this case, a time window needs to be defined or configured to compute the SLIV.

[0103] Optionally, for method 1, when the length of the window is When calculating SLIV for a sub-block, L in formula (1) can be replaced with n, i.e.:

[0104] At this point, a single transmission of one TB will be limited to not crossing this window. For L1=2 and a window length of 14, this means it will not cross more than 28 symbols.

[0105] If spanning windows is allowed, it is even simpler to calculate SLIV = (n-1) +S.

[0106] The same calculation method applies to Method 2.

[0107] Optionally, the aforementioned sub-block can be one or more time slots. When the subcarrier spacing is large and the symbol length is small, uplink transmission needs to last for a certain period of time to achieve adequate coverage. In this case, a sub-block can be configured as one or more time slots for the UE. Since the duration of a time slot is already very short, the number of occupied sub-blocks can be indicated more simply. The starting position can also be indicated by a sub-block or time slot. For greater flexibility, different fields or parameters can be used in the DCI or RRC to indicate the number of transmitted sub-blocks and the starting position respectively.

[0108] Method 3: Determine the sub-block granularity based on the subcarrier spacing.

[0109] Since the subcarrier spacing determines the length of symbols and time slots, the size of the sub-block in the above method can be predefined for each subcarrier spacing. As shown in Table 2, the correspondence between subcarrier spacing and sub-block size can be predefined in the protocol or configured via signaling. Multiple subcarrier spacings can correspond to the same or different sub-block sizes. For example, 15kHz~120kHz all correspond to 1 symbol, while 240kHz, 480kHz, and 960kHz correspond to 28, 56, and 112 symbols respectively. The sub-block size can be represented by time units such as the number of symbols or the number of time slots.

[0110] Table 2: Correspondence between subcarrier spacing and subblock size

[0111] Optionally, the sub-block size is determined based on a configured parameter n and the subcarrier spacing. For example, for a subcarrier spacing of A kHz (e.g., A=120), if the sub-block size is n symbols (e.g., n=1), then the subcarrier spacing is m. When the frequency is A kHz (e.g., m=2, A=120, i.e., 240kHz), the sub-block size is n. m symbols (i.e., n) m = 2 symbols).

[0112] Alternatively, in the protocol, the subcarrier spacing can be represented by corresponding or other parameters used to calculate the subcarrier spacing.

[0113] Optionally, since a single PRB in the frequency domain may occupy a large bandwidth when the subcarrier spacing is large, the base station can configure different sizes for the frequency domain resource subblocks, or predefine the size of the frequency domain resource subblocks based on the subcarrier spacing. In this case, the number of symbols in the time domain subblock can be determined by the number of frequency domain subblocks according to a predefined relationship. For example, when the frequency domain subblock consists of 1 subcarrier, the time domain subblock size is 14 symbols; when the frequency domain subblock consists of 2 subcarriers, the time domain subblock size is 7 symbols, and so on. Therefore, when the base station indicates the size of the frequency domain subblock to the UE, the corresponding size of the time domain subblock can be inferred. Alternatively, when the base station indicates the size of the time domain subblock to the UE, the corresponding size of the frequency domain subblock can be inferred.

[0114] Optionally, the granularity of sub-blocks can be configured separately for uplink, downlink, or bypass data transmission and / or control channel transmission. That is, the same or different sub-block granularities can be configured.

[0115] Optionally, for the methods mentioned above, the UE can also determine the data transmission mapping type (Type A and Type B) according to the indication in the TDRA table. In particular, for this new resource allocation method, only one of the multiple transmission types may be predefined or configured (additionally configured).

[0116] Optionally, although the transmission of a transport block spans multiple time units, repetition can be further introduced to achieve better coverage or higher reliability. The number of repetitions can be configured individually, or, as shown in Table 1, a repetition count k can be added to the TDRA table for joint indication along with other time-domain resource allocation information.

[0117] The second aspect: Frequency domain resource allocation In NR, there are two methods for allocating frequency domain resources: Type 0 Resource Allocation Method: Based on predefined criteria and / or base station configuration, a given bandwidth of frequency domain resources is divided into several resource block groups (RBGs). A bitmap is then used to indicate one or more resource block groups occupied by a TB transmission. Each resource block group includes one or more physical resource blocks (PRBs) or virtual resource blocks. The number of physical resource blocks included in each resource block group is defined or configured according to the given bandwidth. Optionally, Table 3 shows the RBG values ​​corresponding to different BWP bandwidths. The base station configures one of the two configurations via RRC.

[0118] Table 3: RBG values ​​or number of subcarriers in a subblock corresponding to different BWP bandwidths.

[0119] Type 1 resource allocation method: In VRB or PRB units, the resource indicator value (RIV) indicates the starting position RB_start and the length of the contiguous resource blocks L_RBs. The resource indicator value RIV is calculated using formulas (1) and (2).

[0120] For large subcarrier spacing, since the bandwidth occupied by a single subcarrier can be hundreds of kilohertz (kHz) or even hundreds of megahertz (MHz), especially for power-constrained uplink transmissions, it is more efficient to concentrate power in a smaller bandwidth for power spectrum density (PSD) boosting than to distribute power across a large bandwidth. PSD boosting can achieve the same or better coverage while conserving spectrum resources, thus supporting more users.

[0121] Optionally, smaller frequency domain resource blocks, such as sub-PRBs (sub-physical resource blocks), can be defined for frequency domain resource allocation. A sub-PRB can have one or more subcarriers. The base station can configure the number of subcarriers in a sub-PRB to the UE. Alternatively, the UE can infer the number based on different subcarrier intervals according to protocol specifications. Specifically, the following methods are possible: Method 1: The base station directly configures the number of subcarriers in a sub-PRB to the UE via signaling (such as RRC, MAC, DCI, etc.). For example, directly configure the number of subcarriers in a sub-PRB to the UE.

[0122] Method 2: Determine the number of subcarriers in the sub-PRB based on the BWP size (the number of frequency domain resource blocks occupied in the BWP) or the bandwidth occupied by the BWP (in Hz). Optionally, one or more sets of sub-PRB subcarrier numbers can be defined or configured one-to-one with the number of frequency domain resource blocks occupied in at least two types of BWPs or the bandwidth occupied by at least two types of BWPs. When multiple sets of subcarrier numbers are defined or configured, the base station can indicate one of the multiple sets of subcarrier numbers to the UE through signaling (such as DCI, MAC, or RRC).

[0123] Optionally, as shown in Table 3, when the BWP occupies 50 PRBs, the number of subcarriers in a sub-PRB is divided into two groups, with the first group having 4 subcarriers and the second group having 8 subcarriers. The base station can further instruct the UE to adopt the first configuration (i.e., the first group) with 4 subcarriers.

[0124] Method 3: Predefine or configure the bandwidth of a Sub-PRB to the UE (e.g., in Hz), and determine the number of subcarriers in a Sub-PRB based on the subcarrier spacing and the bandwidth of the Sub-PRB.

[0125] Optionally, if the bandwidth of a sub-PRB is configured to be 1.44MHz, then for a subcarrier spacing of 120kHz, a sub-PRB can have 1.44MHz / 120kHz = 12 subcarriers; for a subcarrier spacing of 240kHz, a sub-PRB can have 1.44MHz / 240kHz = 6 subcarriers; for a subcarrier spacing of 480kHz, a sub-PRB can have 1.44MHz / 480kHz = 3 subcarriers; for a subcarrier spacing of 1.44Hz, a sub-PRB can have 1 1.44MHz subcarrier, and so on.

[0126] Method 4: Calculate the number of sub-PRB subcarriers based on the number of time-domain resource allocation symbols for a TB transmission or the number of symbols in a time-domain unit.

[0127] Optionally, the total number of REs in a scheduling resource can be predefined or configured (e.g., 144 REs). The number of subcarriers in a sub-PRB multiplied by the number of symbols in a time-domain unit (or the number of time-domain resource allocation symbols for a TB transmission) equals the total number of REs in that scheduling resource. For example, if the total number of REs in a scheduling resource is 168 REs and the number of symbols in a time-domain unit is 28, then the number of subcarriers in that sub-PRB is 168 / 28 = 6, which is the total number of REs in the scheduling resource.

[0128] Optionally, in methods 1 to 4 above, the number of subcarriers in the Sub-PRB can be replaced with the number of RBs or the number of RBGs, thereby allocating a larger bandwidth at once and reducing the bit overhead required for time-domain resource allocation. In this case, it can be named a super resource block group (super RBG) based on its characteristics. In method 4 above, the symbols in the time domain can be replaced with other time units in the time domain, such as a set of symbols, a time slot, a subframe, etc.

[0129] For frequency domain resource allocation, one of the two methods (Type 0 or Type 1) in NR resource allocation can be applied. This also applies to other resource allocation methods. Here, a frequency domain resource scheduling unit is one or more Sub-PRBs (or one or more super RBGs).

[0130] Optionally, in the Type 2 frequency domain resource allocation method, it is necessary to indicate the starting frequency domain resource location and the size of the occupied resources. In this case, different granularities can be used for indication. For example, any of the methods 1-4 above can be used to determine the first frequency domain granularity (e.g., a sub-PRB, a PRB, or a super RBG) to indicate the starting location of the frequency domain resources occupied in a single transmission. Any of the methods 1-4 above can be used to determine the second frequency domain granularity (e.g., a sub-PRB, a PRB, or a super RBG) to indicate the size of the frequency domain resources occupied in a single transmission.

[0131] The technical solution provided in this application has at least the following beneficial effects: It enables more efficient resource allocation for transport block transfers.

[0132] Example 2 Based on the same inventive concept as in Embodiment 1, this application also provides a UE, the structural schematic diagram of which is shown below. Figure 9 As shown, UE30 includes a first processing module 301 and a second processing module 302.

[0133] The first processing module 301 is used to receive resource allocation information; The second processing module 302 is used to determine, based on resource allocation information, the time-domain resource location occupied by a transport block in one transmission and / or the total symbol length occupied by a transport block in one transmission, wherein a transport block occupies multiple time units in one transmission; and / or, The second processing module 302 is used to determine the number of subcarriers in at least one sub-physical resource block according to resource allocation information, and to determine the frequency domain resource location occupied by a transmission block according to the number of subcarriers in at least one sub-physical resource block, wherein the number of subcarriers in at least one sub-physical resource block is less than the number of subcarriers in a physical resource block.

[0134] Optionally, the resource allocation information includes at least one of the following: the number of time units occupied by a transport block, the location information of the first time unit, the start location information, the length information, the number of symbols in each time unit, the granularity of at least one time-domain sub-block, the number of time-domain sub-blocks, a time-domain resource allocation TDRA table for indicating time-domain resource allocation information, and the sequence number in the time-domain resource allocation TDRA table for indicating time-domain resource allocation information. The frequency-domain resource allocation information includes at least one of the following: subcarrier spacing, granularity of frequency-domain resource sub-blocks, the number of subcarriers in at least one sub-physical resource block, the size of the bandwidth block (BWP), and the size of the bandwidth occupied by the BWP.

[0135] Optionally, the starting position information includes the position information of the starting symbol in a time unit; the length information includes symbol length information; and the granularity of the sub-block includes at least one symbol or at least one time unit. Optionally, the configuration information includes information configured by the base station to the UE via Radio Resource Control (RRC) for indicating transmission scheduling; the scheduling information is information transmitted by the base station to the UE via Downlink Control Information (DCI) for indicating transmission scheduling.

[0136] Optionally, the number of time units can be defined or configured as any of the following: The number of time units includes the number of starting time units, the number of complete time units excluding the time units occupied by the starting and ending positions, and the number of ending time units; The number of time units includes the number of time units excluding those occupied by the start and end positions; The number of time units includes the number of complete time units.

[0137] Optionally, determining the time-domain resource location occupied by a transport block in one transmission and / or the total symbol length occupied by a transport block in one transmission based on resource allocation information includes at least one of the following: determining the time-domain resource location occupied by a transport block in one transmission and / or the total symbol length occupied by a transport block in one transmission based on the resource allocation information including the starting symbol location of a transport block in the first time unit, the symbol length in the last time unit, and the number of time units; The total symbol length is determined based on at least one of the following parameters included in the resource allocation information: the parameter indicating the number of time units occupied by a transport block, the start position information, the length information, the number of symbols in each time unit, and the number of time domain sub-blocks.
