Description

Resource determination method and equipment

Technical Field

The present application relates to the field of wireless communication technologies, and in particular, to a resource determination method and device.

Background

Most of NR (New Radio ) systems use frequency points higher than those of LTE (Long Term Evolution), however, since the deployment cost of a base station is very high, an operator system can achieve coverage performance equivalent to that of an LTE system with an NR system, and thus NR base station devices can be directly upgraded or deployed on an original LTE site.

In the NR system, one transmission (or repetition) of one Transport Block (TB) occupies all or part of symbols in one slot (slot) in time, and occupies one or more Physical Resource Blocks (PRBs) in a frequency domain. However, since the uplink is a power-limited system, even if more PRBs are allocated, the coverage enhancement effect cannot be achieved. Conversely, the uplink transmission time should be extended as much as possible. Although NR currently supports repeated transmission, NR cannot support transmission of one TB across multiple slots when the number of PRBs occupied in the frequency domain is small, since current time-domain resource scheduling is at most one slot. Although the current system supports the performance improvement by using Redundancy Version (RV) rotation method compared to a transmission with a lower code rate (one TB spanning multiple slots), when the code rate is too high, the performance is still limited.

Furthermore, for higher frequency transmissions, such as >52.6GHz, larger subcarrier spacings, such as several hundred kHz, need to be employed. Then, a time of one slot is made very short. Thus, to meet the uplink coverage requirement, a longer transmission time is required. Therefore, how to more effectively indicate the time domain and frequency domain resource allocation is a problem to be solved.

For better understanding and description of aspects of embodiments of the present application, some of the techniques involved in embodiments of the present application are briefly described below.

Fig. 1 illustrates an example of a wireless communication system 100, wherein the wireless communication system 100 includes one or more fixed infrastructure elements forming a network distributed over a geographic area. Infrastructure elements may include APs (Access points), ATs (Access terminals), BSs (Base stations), Node-BS (Node BS), enbs (evolved nodebs), gnbs (next generation Base stations), etc., or other terms used in the art.

As shown in fig. 1,

infrastructure elements

101 and 102 serve several MSs (mobile stations) or UEs or terminal devices or

users

103 and 104 in a service area within a cell or cell sector. In some systems, one or more BSs are communicatively coupled (core to) to a controller forming an access network, the controller being communicatively coupled to one or more core networks. The present examples are not limited to any one particular wireless communication system.

In the time and/or frequency domain,

infrastructure elements

101 and 102 transmit DL (Downlink) communication signals 112 and 113 to MSs or

UEs

103 and 104, respectively. The MSs or

UEs

103 and 104 communicate with the

infrastructure elements

101 and 102 via UL (Uplink) communication signals 111 and 114, respectively.

Alternatively, the mobile communication system 100 is an OFDM (Orthogonal Frequency Division Multiplexing)/OFDMA (Orthogonal Frequency Division Multiplexing Access) system including a plurality of base stations including the base station 101 and the base station 102 and a plurality of UEs including the UE103 and the UE 104. Base station 101 communicates with UE103 via UL communication signal 111 and DL communication signal 112.

When the base station has a Downlink packet to send to the UE, each UE obtains a Downlink allocation (resource), such as a set of radio resources in a PDSCH (Physical Downlink Shared Channel). When the UE needs to send a packet in the Uplink to the base station, the UE obtains a grant from the base station, wherein the grant allocates a PUSCH (Physical Uplink Shared Channel) containing a set of Uplink radio resources. The UE acquires Downlink or uplink scheduling information from a PDCCH (Physical Downlink Control Channel) dedicated to itself. Downlink or uplink scheduling Information and other Control Information carried by the PDCCH are referred to as DCI (Downlink Control Information).

Fig. 1 also shows different physical channels for downlink 112 and uplink 111 examples. The downlink 112 includes a PDCCH121, a PDSCH122, a PBCH (Physical Broadcast Channel) 123, and a PSS (Primary Synchronization Signal)/SSS (Secondary Synchronization Signal ) 124. In the 5G NR, PSS, SSS, and PBCH together form an SSB (SS/PBCH block) 125. PDCCH121 transmits DCI120 to the UE, i.e., DCI120 is carried through PDCCH 121. PDSCH122 transmits downlink data information to the UE. The PBCH carries MIB (Master Information Block) for UE early discovery and cell-wide coverage (cell-wide coverage). The Uplink 111 includes a PUCCH (Physical Uplink Control Channel) 131 carrying UCI (Uplink Control Information) 130, a PUSCH132 carrying Uplink data Information, and a PRACH (Physical Random Access Channel) 133 carrying Random Access Information. Besides the traditional cellular networking mode, the invention can also be applied to a resource allocation method of bypass (sidelink) transmission. The bypass transmission refers to communication between terminals.

Optionally, the wireless communication network 100 uses OFDMA or a multi-carrier architecture, including AMC (Adaptive Modulation and Coding) on the downlink and next generation single carrier FDMA architecture or multi-carrier OFDMA architecture for UL transmission. FDMA-based single-carrier architectures include 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 OFDMA systems are also included.

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

In the NR system, the frequency domain resource allocation minimum unit 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 size of RBG is determined according to the base station configuration and the bandwidth of BWP (bandwidth block). In the frequency domain, a Transport Block (TB) occupies at most 14 symbols in a time slot, which is indicated in the Time Domain Resource Allocation (TDRA) in the downlink control information DCI. Before establishing an RRC (Radio Resource Control) link, a TDRA table is defined in advance in a protocol, which includes: a parameter K0 (for PDSCH) or K2 (for PUSCH) for indicating a slot (slot) position, a symbol start position S and a symbol length L within a slot, and a data transmission mapping Type (Type a and Type b of DMRS mapping). For the downlink data channel PDSCH, the predefined TDRA table also includes an indication of the DMRS location. After establishing the RRC, the base station may configure a new TDRA table to the UE through the RRC to indicate the time domain resource allocation information. In order to reduce signaling overhead, a Start and Length Indicator (SLIV) indicating joint coding of a start symbol S and a length L is used to indicate a symbol start position S and a symbol length L within a slot.

A Physical Uplink Shared Channel (PUSCH) is taken as an example for explanation, and the same method is applied to a Physical Downlink Shared Channel (PDSCH).

The slot of the PUSCH transmitted by the UE is determined as K2

Where n is the slot where the scheduling DCI is located, K2 is determined based on the value of PUSCH (numerology), and μ_PUSCHAnd mu_PDCCHSub-carrier spacing (subcarrier spacing) for PUSCH and PDCCH, respectively. The starting symbol S allocated to the PUSCH with respect to the starting slot, and the number L of consecutive symbols calculated from the symbol S are determined by the following equations (1) and (2) and according to the indication (SLIV) of the start and length corresponding to the row of the index:

if (L-1) ≦ 7, SLIV ≦ 14 · (L-1) + S (equation 1),

otherwise, SLIV · (14-L +1) + (14-1-S) (equation 2),

wherein L is more than 0 and less than or equal to 14-S.

And setting the mapping Type of the PUSCH according to the mapping Type corresponding to the indexed row based on the PUSCH mapping (mapping) types of the Type A and Type B modes defined by section 6.4.1.1.3 in the protocol TS 38.211. The configuration method of the TDRA table of the PDSCH and the TDRA table of the PUSCH is similar.

In NB-IoT systems, to support coverage enhancement, the concept of Resource Units (RUs) is defined such that one transmission of one TB can span multiple subframes (subframes). In NB-IoT, one RU includes the same number of Resource Elements (REs). The length of an RU is calculated by indicating the number of carriers occupied by each RU, and further, the length of a corresponding Transport Block (TB) size is calculated by indicating the number of RUs.

For an OFDM communication system with a large subcarrier spacing (e.g., a subcarrier spacing of 120kHz or 240kHz) and/or a system requiring coverage enhancement, especially a system requiring uplink coverage enhancement, one transport block also needs to be in multiple time domain resource units (e.g., slots, subframes, time units (time units) in one or several symbol (symbols) time domain, etc.). A lower code rate and thus better performance may be provided than with multiple repetitions (multiple repetitions) or multiple transmissions (multiple transmissions), especially when the transmission bandwidth is limited.

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

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

In the embodiment of the application, more effective resource allocation of transmission block transmission is realized.

The above embodiments of the present application are described in full detail by the following examples:

the method is suitable for the downlink channel, the uplink channel or the bypass channel.

In order to support transmission of one TB in multiple time units in the first aspect, several methods for supporting time domain resource allocation are described below.

The method comprises the following steps: the TDRA table indicates the starting symbol position S in the first time unit, the symbol length in the last time unit, and the number of time units n.

Alternatively, the resource location is determined according to the TDRA table and the new parameter n added to each row, where n is used to indicate the number of time units occupied by one TB. In another example, the new parameter n may be indicated by additional signaling, wherein the additional signaling comprises a joint indication of one or more of: RRC, MAC, DCI. Compared with the two methods, the former method can save DCI overhead for indicating TDRA, and the latter method can reduce configuration overhead of a TDRA table RRC. The UE determines the initial time slot position according to the parameter K0 or K2 for indicating the time slot (slot) position indicated in the TDRA table, and determines the initial symbol position according to the symbol initial position S in the time slot in the TDRA table. And the UE determines the number of the time slots occupied by the TB according to the number n of the time units occupied in the TDRA table, and determines the number L of the symbols occupied in the last time slot according to the length L of the symbols in the TDRA table. The number n of time units may be defined or configured as one of the following:

● (A) the number of time units n includes the total number of time units of the start, the time units of the complete occupation except the time units occupied by the start position and the end position, and the time units of the end;

● (B) the number of time cells n comprises only the number of time cells other than the time cells occupied by the start and end positions;

● (C) the number of time cells n includes the number of time cells that occupy a complete time cell.

Specifically, if S ═ 0 or L is the number of symbols in one time unit, then inclusion is performed, otherwise exclusion is not performed.

Alternatively, the time cell may be predefined as several symbols, such as 14 symbols. At this time, one time unit is one slot in one NR system. However, one transmission of an actual TB may occupy a part of symbols in one slot.

Optionally, the UE calculates a total symbol length L _ all occupied by the TB transmission according to at least one of: the parameter n for indicating the number of time units occupied by a TB, the starting symbol S, the symbol length L, and the number of symbols in each time unit L _ unit. The UE calculates a Transport Block Size (TBS) from the L _ all. Specifically, with the above method (a), L _ all ═ L _ unit × n- (L _ unit-L) -S.

Alternatively, table 1 is an example of a table of PUSCH resource allocation. For the RRC configured TDRA table, the starting symbol S and the symbol length L are obtained by indicating the SLIV and calculating according to equation (1). The UE acquires a TDRA index number for indicating time domain resource allocation according to DCI or RRC (for example, for a configured grant type one (configured grant type 1)), and the TDRA index number is indicated as index 1 in table 1. Then, as shown in fig. 4, the UE obtains the time domain resource configuration as: transmission starts at the 3 rd symbol (symbol 2) of the jth slot after the slot in which the PDCCH is received, to the 8 th symbol (symbol 7) position of the j +3 th slot. The PUSCH has a subcarrier spacing of 15kHz, and j is 1 according to a predefined rule.

At this time, if L _ unit is 14, the total number of occupied symbols for the transmission is L _ all 14 × 4- (14-8) -2 ═ 48.

Table 1: TDRA table

The second method comprises the following steps: and determining the position of time domain resource allocation according to the starting position of the sub-block indicated by the SLIV (or the starting symbol S and the symbol length L indicated in the TDRA table) and the number n of the sub-blocks. The number n of sub-blocks may be a new column (a new parameter is added to each index) in the TDRA table, or may be additionally indicated through signaling. Wherein the additional signaling comprises a joint indication of one or more of: RRC, MAC, DCI.

Alternatively, one subblock is defined as L symbols. The number of symbols in a sub-block may be less than or equal to the number of symbols in a time unit.

The SLIV indicates the starting position and symbol length in one time unit occupied by the first sub-block. According to the SLIV, the initial position and the symbol length occupied by the first sub-block in a time unit can be determined. In addition, the ending position can be determined according to the starting position and the symbol length of the first sub-block in a time unit. Wherein the end position may be within the first time unit or within other time units, i.e. a plurality of time units. Furthermore, the temporal position of the other sub-blocks may be inferred according to predefined rules. The method can be specifically realized by one of the following methods:

the method A comprises the following steps: each sub-block occupies the same symbol allocation (same symbol allocation) in consecutive n time units.

Alternatively, taking table 1 index 1 as an example, S is 2, L is 8, and n is 4. As shown in fig. 5, the TB transmission is continuous 8 symbols starting at the 3 rd symbol (symbol 2) of the slot j, and continuous 8 symbols starting at the 3 rd symbol (symbol 2) in each of the slot j +1, the slot j +2, and the slot j + 3.

The method B comprises the following steps: the symbol allocation occupied by the first sub-block is determined according to the SLIV (or the starting symbol S and the symbol length L indicated in the TDRA table), and the next symbols available for uplink or downlink data transmission are continuously occupied n times, that is, n symbols with the length L are occupied in sequence.

Alternatively, taking table 1 index 1 as an example, S is 2, L is 8, and n is 4. As shown in fig. 6, the TB transmission starts 8 consecutive symbols at the 3 rd symbol (symbol 2) of slot j and then n-1 consecutive sub-blocks. Wherein each sub-block comprises 8 symbols. As shown in fig. 6, the 2 nd sub-block occupies symbols 10 to 13 of the slot j and symbols 0 to 3 of the slot j +1, the 3 rd sub-block occupies symbols 4 to 11 of the slot j +1, the 4 th sub-block occupies symbols 12 to 13 of the slot j +1 and symbols 0 to 5 of the slot j + 2.

Optionally, the UE calculates a total symbol length L _ all occupied by the TB one-time transmission according to at least one of the following: the parameter n for indicating the number of sub-blocks occupied by one TB, the number L of symbols in each sub-block, determines the total number L _ all of symbols for transmitting the TB, which is L × n. The UE calculates a Transport Block Size (TBS) from the L _ all.

For index 1 in table 1 above, L _ all ═ L × n ═ 8 × 4 ═ 32 can be calculated.

The third method comprises the following steps: the time unit position K is indicated in the TDRA table, as well as the starting symbol position S in the starting time unit, and the total symbol length L _ all. Where L _ all may be greater than the number of symbols in a time unit (e.g., a slot or a subframe). In this method, one time unit may be one time slot.

Specifically, there are two methods to indicate S and L _ all:

method X: the TDRA table is configured by RRC, wherein a start symbol position and a total symbol length L _ all are configured respectively.

Alternatively, it is simpler and straightforward to configure S and total symbol length L _ all separately. No additional SLIV calculation is required to be introduced to support the number of symbols in L _ all of approximately one time cell. For example, the start symbol S position corresponding to index 3 in table 1 is 2, and the total symbol length L _ all is 28. Wherein, a time slot time unit is 14 symbols, and the total length of the symbols is about the number of symbols in a time unit.

Method Y: the starting symbol position S, as well as the total symbol length L _ all, are jointly coded and indicated in the TDRA table.

Alternatively, if the indication of the starting symbol position S is within a time unit (e.g., a slot or subframe). At this time, the position of the first time unit occupied by one TB transmission may be additionally indicated in the TDRA table, for example, a slot indicating transmission start with K0 for PDSCH and K2 for PUSCH. In one example, if the number of symbols in a slot is 14 and 0 ≦ S <14, SLIV may be calculated according to the following method:

if L _ all is less than or equal to 14, then

● if L _ all + S is less than or equal to 14

● if (L _ all-1) ≦ 7

■SLIV＝14×(L_all-1)+S，

● else

■SLIV＝14×(7-L_all+1)+(7-1-S)

● if L _ all + S >14

● if (L _ all-1) ≦ 7

■SLIV＝14×(14-L_all+1)+(14-1-S)

● else

■SLIV＝14×(L_all-1)+S

If L _ all >14, then

●SLIV＝14×(L_all-1)+S

In the third method, the total number of symbols occupied by one transmission is L _ all, and is directly determined according to the TDRA or calculated according to the SLIV in the TDRA.

Alternatively, in the former three methods, the time unit may be a time slot, and the number of symbols in the sub-block is usually less than or equal to the number of symbols of one time unit. To reduce overhead, the number of symbols in a sub-block may be greater than the number of symbols in a time unit (e.g., slot). In the method four described below, the base station may configure several symbol numbers and/or slot numbers as a new sub-block, and then replace the symbol with the sub-block as the smallest time-domain scheduling resource granule.

The method four comprises the following steps: the UE obtains the granularity of at least one sub-block according to the configuration of the base station; and determining the time domain resource position of one TB according to the initial resource position S in the time domain resource indication domain indicated by the base station and the number n of the sub-blocks. The method specifically comprises the following implementation methods:

the method comprises the following steps: the UE obtains a subblock with a granularity of L1 symbols or L1 time units (e.g., slots, etc.) according to the configuration of the base station. The indication of the starting resource location S starts transmission at the position of the several sub-blocks.

Alternatively, as shown in fig. 7, the base station configures granularity L1 of one sub-block to be 2 symbols, and then S-2 and n-8 represent that one transmission of one TB starts from the 3 rd sub-block and occupies 8 sub-blocks. That is, symbols 4 to 13 of slot j and symbols 0 to 5 of slot j +1 are occupied.

The calculation of the total symbol length occupied by a TB for one transmission is determined according to the number of symbols in a sub-block and the number of sub-blocks. When L1 indicates the number of symbols, the total number of symbols is L _ all — L1 × n. When L1 is the number of slots, assuming that a slot has 14 symbols, the number of symbols is L _ all — 14 × L1 × n.

The method 2 comprises the following steps: the UE obtains a sub-block 1 having a size of L1 symbols or L1 time units (e.g., slots, etc.) for deciding a start position and a sub-block 2 having a size of L2 symbols or L1 time units (e.g., slots, etc.) for a transmission length according to the configuration of the base station. The indication of the starting resource location S starts transmission at the position of the several sub-blocks 1. The number of symbols actually transmitted is determined according to the size L2 of sub-block 2.

Alternatively, as shown in fig. 8, the size L1 of sub-block 1 configured to indicate the start position is 2 symbols, and the size L2 of sub-block 2 configured to indicate the symbol length is 8 symbols, then S-2 and n-4 represent one transmission of one TB, starting from the 3 rd sub-block with length of 2 symbols, occupying 4 sub-blocks with length of 8 symbols. That is, symbols 4 to 13 occupying slot j, all symbols of slot j +1, and symbols 0 to 7 occupying slot j + 2.

The calculation of the total symbol length occupied by a TB transmission is determined by 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 L _ all — L2 × n. When L2 is the number of slots, assuming that a slot has 14 symbols, the number of symbols is L _ all — 14 × L2 × n.

Compared to method 1, method 2 is more flexible in indicating the starting position.

Alternatively, for the above method 1 and method 2, the time slot j may be decided according to the decision method of the time slot position as in the previous method (e.g., according to K0 or K2 in the TDRA table). Or, the time slot j may be directly predefined as the time slot occupied by the corresponding PDCCH transmission or the position of the xth time slot after the time slot occupied by the corresponding PDCCH transmission. Preferably, the time slot j is an indication that the time slot occupied by the corresponding PDCCH transmission is more suitable for the PDSCH, and the position of the xth time slot after the time slot occupied by the corresponding PDCCH transmission is more suitable for the PUSCH indication. Where x may be determined based on the processing capability of the UE, and/or the subcarrier spacing.

Alternatively, for methods 1 and 2 above, S and n may be jointly encoded as well. Thus, a time window (window) needs to be defined or configured to calculate the SLIV.

Alternatively, for method 1, when the window length is

For each subblock, the calculation of SLIV may replace L in equation (1) with n, that is:

● if

Then

● if

● else

Wherein

And is

At this point, one transmission of one TB may be restricted from crossing this window. For L1 ═ 2, the window length is 14, i.e., no more than 28 symbols are spanned.

Simpler calculable if the window is allowed to be crossed

The same idea of the above calculation applies for method 2.

Alternatively, the sub-block may 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 time in order to obtain a certain coverage. Then at this point, the UE may be configured with one sub-block as one or more time slots. Since the time of one slot is already short, the number of occupied sub-blocks can be indicated more simply. The start position may also be indicated in one sub-block or time slot. For more flexibility, the number of transmission sub-blocks, and the starting position may be indicated in DCI or RRC with different fields or parameters, respectively.

The method 3 comprises the following steps: the subblock granularity is determined according to the subcarrier spacing.

Since the subcarrier spacing determines the length of the symbols and time slots, the size of the sub-blocks in the above-described method may be predefined for each subcarrier spacing. As shown in table 2, the correspondence between the subcarrier spacing and the subblock size may be predefined in the protocol or configured through signaling. The multiple subcarrier spacings may correspond to the same or different sub-block sizes. For example, 15 kHz-120 kHz each correspond to a symbol, and 240kHz, 480kHz and 960kHz each correspond to 28,56,112 symbols. The sub-block size may be expressed by a time unit such as the number of symbols or the number of slots.

Table 2: correspondence between subcarrier spacing and subblock size

Subcarrier spacing	Number of symbols in sub-block (or number of time slots in sub-block)
		15kHz～120kHz	14(1)
240kHz	28(2)
		480kHz	56(4)
960kHz	112(8)

Optionally, the sub-block size is determined according to a configured parameter n and a sub-carrier spacing. For example, for a sub-carrier spacing of a kHz (e.g., a ═ 120), the sub-block size is n symbols (e.g., n ═ 1), and then for a sub-carrier spacing of m × 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).

Alternatively, in a protocol, the subcarrier spacing may be represented by other parameters corresponding to or used to calculate the subcarrier spacing.

Alternatively, when the subcarrier spacing is large, one PRB may occupy a large bandwidth in the frequency domain. The base station may configure different sizes of the frequency domain resource sub-blocks or predefine the sizes of the frequency domain resource sub-blocks according to the subcarrier spacing. In this case, the number of symbols of the time domain sub-blocks may be determined by the number of frequency domain sub-blocks according to a predefined relationship. For example, when the frequency domain sub-block is 1 sub-carrier, the sub-block size of the time domain is 14 symbols; when the frequency domain sub-block is 2 sub-carriers, the sub-block size of the time domain is 7 symbols, etc. Then, when the base station indicates the frequency domain sub-block size to the UE, the corresponding time domain sub-block size may be inferred. Alternatively, when the base station indicates the time domain sub-block size to the UE, the corresponding frequency domain sub-block size may be inferred.

Optionally, the granularity of the sub-blocks may be configured for uplink or downlink or bypass data transmission and/or control channel transmission, respectively. I.e. the same or different sub-block granularity may be configured.

Optionally, for the above methods, the UE may further determine the data transmission mapping types (Type a and Type b) according to the indication in the TDRA table. In particular, only one of the transmission types may be predefined or configured (additionally configured) for this new resource allocation method.

Optionally, although the transmission of one transport block spans multiple time units, repetition may be further introduced for better coverage or higher reliability. The repetition number may be configured separately, or as shown in table 1, an item of repetition number k is added to the TDRA table, and is jointly indicated together with other time domain resource allocation information.

In a second aspect: frequency domain resource allocation

In NR, there are two methods for frequency domain resource allocation:

type (Type)0 resource allocation method: according to a predefined criterion and/or configuration of a base station, dividing frequency domain resources of a given bandwidth into a plurality of Resource Block Groups (RBGs), and then indicating one or more resource block groups occupied by TB transmission by means of a bitmap (bitmap). Wherein each resource block group includes one or more Physical Resource Blocks (PRBs) or virtual resource blocks (virtual resource blocks). The number of physical resource blocks included in each resource block group is defined or configured according to the size of a given bandwidth. Optionally, table 3 is the values of RBGs for different BWP bandwidths. The base station configures one of two configurations through RRC.

Table 3: RBG value corresponding to different BWP bandwidth or subcarrier number in one sub-block

Bandwidth Block Size (Bandwidth Part Size)	Configuration 1	Configuration 2
			1–36	2	4
37–72	4	8
			73–144	8	16
145–275	16	16

Type (Type)1 resource allocation method: the starting position RB _ start and the continuous resource block length L _ RBs of the resource are indicated by a Resource Indication Value (RIV) in units of VRBs or PRBs. The resource indication value RIV is calculated by the methods of formula (1) and formula (2).

For large subcarrier spacing, power spectral enhancement (PSD) boosting is not focused on a small bandwidth, as the bandwidth occupied by one subcarrier may be several hundred kilohertz (kHz) or even several hundred megahertz (MHz), especially for power limited upstream transmission, as it distributes power over a large bandwidth. PSD enhancement can achieve the same or better coverage while saving spectrum resources. So that more users can be supported.

Alternatively, the frequency domain resource allocation may be performed by a method of defining smaller frequency domain resource blocks, such as sub-PRB (sub-physical resource block). One sub-PRB may have one or more subcarriers. The base station may configure the UE with the number of subcarriers in one sub-PRB. Or the UE may infer from different subcarrier spacings, as specified by the protocol. Specifically, there may be several methods:

the method comprises the following steps: the base station directly configures the number of sub-carriers in one sub-PRB to the UE through signaling (such as RRC, MAC, DCI and the like). For example, the number of subcarriers in one sub-PRB is directly configured to the UE.

The method 2 comprises the following steps: the number of sub-carriers in a sub-PRB is determined according to the BWP size (the number of frequency domain resource blocks occupied in the BWP) or the size of the bandwidth (in Hz) occupied by the BWP. Optionally, the number of one or more sets of sub-PRB sub-carriers corresponding to each other may be defined or configured for the number of frequency-domain resource blocks occupied by the at least two BWPs or the bandwidth occupied by the at least two BWPs. When multiple groups of subcarrier numbers are defined or configured, the base station may indicate one of the multiple groups of subcarrier numbers to the UE through signaling (e.g., one of DCI, MAC, or RRC).

Optionally, as shown in table 3, when BWP occupies 50 PRBs, the number of subcarriers in one sub-PRB is two groups, where the first group is 4 subcarriers, and the second group is 8 subcarriers. The base station may further indicate to the UE to employ the first configuration (i.e., the first group) of 4 subcarriers.

The method 3 comprises the following steps: the bandwidth of one Sub-PRB (for example, Hz is used as a unit) is predefined or configured to the UE by the base station, and the number of the Sub-carriers in one Sub-PRB is determined according to the Sub-carrier interval and the bandwidth of the Sub-PRB.

Alternatively, the bandwidth of one sub-PRB is configured to be 1.44MHz, and then for a subcarrier interval of 120kHz, there may be 1.44MHz/12 subcarriers of 120 kHz; for a subcarrier spacing of 240kHz, one sub-PRB may have 1.44MHz/240 kHz-6 subcarriers; for a subcarrier spacing of 480kHz, one sub-PRB may have 1.44MHz/480 kHz-3 subcarriers; for a sub-carrier spacing of 1.44Hz, one sub-PRB may have 1 sub-carrier of 1.44MHz, and so on.

The method 4 comprises the following steps: and calculating the number of sub-PRB subcarriers according to the number of the time domain resource allocation symbols transmitted by one TB or the number of the symbols in one time domain unit.

Optionally, the total number of REs in one scheduling resource (e.g., 144 REs) is predefined or configured in advance, and the number of subcarriers in one sub-PRB multiplied by the number of symbols in one time domain unit (or the number of time domain resource allocation symbols for one TB transmission) is equal to the total number of REs in the scheduling resource. For example, if the total number of REs in one scheduling resource is 168 REs, and the number of symbols in one time domain unit is 28, the number of subcarriers in the sub-PRB is 168/28 — 6, which is the total number of REs in the scheduling resource.

Optionally, in the methods 1 to 4, the number of subcarriers in a Sub-PRB may be replaced by the number of RBs, or the number of RBGs, so that a larger bandwidth may be allocated at a time, thereby reducing the bit overhead required for time domain resource allocation. At this time, it may be named super RBG (super RBG) in terms of its characteristics. In the above method 4, the symbols in the time domain may be replaced with time units in other time domains, such as a set of symbols, a slot, a subframe, etc.

For frequency domain resource allocation, one of two methods (Type 0 or Type 1) in resource allocation in NR may be applied. The same applies to other resource allocation methods. Here, one frequency-domain resource scheduling unit is one or more Sub-PRBs (or one or more super RBGs).

Optionally, in the Type 2 frequency domain resource allocation method, a starting frequency domain resource location and an occupied resource size need to be indicated. At this time, indication may be performed with different granularities. For example, a first frequency-domain granularity (e.g., one sub-PRB or one super RBG) is determined by any of the methods 1-4, and is used to indicate a starting position of a frequency-domain resource occupied by a transmission. The second frequency-domain granularity (e.g., as one sub-PRB or one super RBG) is determined by any of the above methods 1-4 to indicate the size of the frequency-domain resource occupied by one transmission.

a more efficient resource allocation for transmission of transport blocks is achieved.
