Description

Technical Field

[0001] This invention relates to the field of wireless communication technology, and in particular to a resource indication method and apparatus. Background Technology

[0002] Based on relevant coverage performance evaluation results, the Physical Uplink Shared Channel (PUSCH) requires coverage enhancement. One possible approach is to enhance PUSCH coverage through retransmission and multi-slot transport block (TB) processing. Multi-slot TB processing refers to treating the sum of bits to be transmitted across multiple time slots as a TB, encoding this TB, and then transmitting it over consecutive time slots. According to the Low Density Parity Check Code (LDPC) coding principle, the increased code length from multi-slot joint coding can lead to greater coding gain, thereby enhancing PUSCH coverage.

[0003] In the prior art, whether PUSCH retransmission is enabled is indicated by higher-layer signaling, and the PUSCH time domain resource allocation and the number of retransmissions are indicated by the DCI 0_X TDRA field. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a resource indication method and apparatus that can flexibly configure the transmission time length of TBprocessing and avoid the increase of DCI overhead.

[0105] Figure 7 This is a schematic diagram of the composition of the resource indicator device according to an embodiment of the present invention. Detailed Implementation

[0106] To make the technical problems, technical solutions and advantages of the embodiments of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0107] Existing signaling methods (such as higher-layer signaling and downlink control information (DCI)) cannot indicate whether multi-slot TB processing is enabled in PUSCH and the number of TB processing slots. The most direct way is to use higher-layer signaling to switch it on and off, but this method is not flexible enough. Indicating the on / off status and number of slots for multi-slot TB processing via DCI will increase DCI overhead.

[0108] On the other hand, when a TB of bits is relatively small and can be transmitted within a single time slot, encoding the sum of bits from multiple time slots as a large TB yields a significant coding gain. However, when a TB contains a large number of bits, it naturally needs to be divided into several coding blocks (CBs) for transmission across multiple time slots. In this case, using repetitive transmission provides a greater coverage gain. With existing protocols, base stations cannot adaptively choose between repetitive transmission and multi-time-slot TB processing.

[0109] This invention provides a resource indication method and apparatus that can solve the problems of PUSCH multi-slot TBprocessing switch and slot number indication, and how the base station should trigger the use of repeated transmission or multi-slot TBprocessing, thereby achieving flexible configuration of TB processing transmission time length and avoiding increased DCI overhead.

[0110] This invention provides a resource indication method, executed by a network-side device, such as... Figure 1 As shown, the method includes:

[0111] Step 101: Send resource configuration information to the terminal. The resource configuration information includes the time domain resource allocation (TDRA) field of the downlink control information (DCI) and the configuration physical uplink control channel (PUSCH) TDRA table to indicate the transmission time length of the PUSCH transport block (TB) processing.

[0112] In this embodiment, the resource configuration information includes a DCI TDRA field (i.e., DCI 0_X TDRA field) and a PUSCH TDRA table, which are used to indicate the transmission time length of PUSCH TB processing. Since the PUSCH TDRA table, which is not associated with TB processing, already has the start position, length flag value SLIV, and repeated transmission number information, by reusing the DCI TDRA field and configuring the PUSCH TDRA table, the transmission time length of TB processing can be flexibly configured, avoiding the increase of DCI overhead.

[0113] In some embodiments, the resource configuration information further includes at least one or more of the following:

[0114] Semi-static indication of multi-slot PUSCH TB processing switch;

[0115] A threshold for TB is used to indicate that when the number of bits in TB is greater than the threshold, multi-slot TB processing is not triggered, using a PUSCH TDRA table not associated with TB processing. When the number of bits in TB is less than the threshold, multi-slot TB processing is triggered, using a PUSCH TDRA table associated with TB processing.

[0116] By configuring a threshold for the size of a TB, repeated transmission or multi-slot TB processing can be triggered. When the number of bits in a TB is less than the threshold, encoding the sum of one or more time slot bits as a large TB yields a greater coding gain. The network side, such as the base station, uses a PUSCH TDRA table associated with TB processing. When the number of bits in a TB is greater than the threshold, the TB naturally needs to be divided into several CBs for multi-slot transmission. The gain from multi-slot TB processing is smaller, and the base station uses a PUSCH TDRA table not associated with TB processing, namely PUSCH-TimeDomainResourceAllocationList.

[0117] By setting a TB size threshold, the network side, such as the base station, can adaptively trigger the use of PUSCH retransmission or multi-slot TB processing to achieve better coverage performance.

[0118] In some embodiments, when the number of bits in a TB is less than a threshold, the configured number of repetitions can be considered as the number of time slots carrying the TB.

[0119] In some embodiments, the PUSCH TDRA table includes a PUSCH mapping type, a PUSCH slot offset K2, a transmission start symbol S, a number of symbols transmitted per slot L, and a number of TB processing slots N, indicating that PUSCH transmission starts from the slot with a slot offset of K2, and TB processing is performed for N consecutive uplink slots, with each slot occupying the S to S+L symbols.

[0120] In some embodiments, the L symbols in each time slot are resources or units carrying TB.

[0121] In some embodiments, the PUSCH TDRA table includes PUSCH mapping type, PUSCH slot offset K2, transmission start symbol S, and transmission symbol number L, indicating that the transmission starts from the Sth symbol of the PUSCH with slot offset K2 scheduled by DCI, and performs TB processing on L consecutive available uplink symbols.

[0122] In some embodiments, L transmission symbols represent resources or units that transmit TB.

[0123] In some embodiments, the PUSCH TDRAtable includes a PUSCH mapping type, a PUSCH slot offset K2, a transmission start symbol S, a number of transmission symbols L, and a number of TB processing slots N, indicating that PUSCH transmission starts from the slot with a slot offset of K2, and TB processing is performed for N consecutive uplink slots.

[0124] In some embodiments, L symbols represent resources or units that carry TB.

[0125] In some embodiments, N*L symbols represent resources carrying TB.

[0126] In some embodiments, the available resources included in the time-domain resources indicated by the resource configuration information are used to determine the size of the transport block.

[0127] In some embodiments,

[0128] The available resources are at least one or more of the following:

[0129] The available resources are those that do not conflict with the downlink symbols or time slot resources configured in a semi-static manner;

[0130] The available resources do not conflict with the downlink symbol or the variable flexible symbol indicated by the Slot Format Indicator (SFI);

[0131] The available resources do not conflict with the downlink symbols and flexible symbols in the semi-statically configured time slots, especially in the case of uplink symbols in special subframes;

[0132] The available resources are uplink symbols in the semi-statically configured time slot resources, specifically for uplink symbols in special subframes.

[0133] The above method can be used to determine the validity of indicated resources and resolve conflicts with other dynamic indications. Based on the determination of resource validity, it can better adapt to the situation in TDD (Time Division Duplex) where only some uplink symbols are available in special subframes.

[0134] This invention provides a resource indication method, executed by a terminal, such as... Figure 2 As shown, the method includes:

[0135] Step 201: Receive resource configuration information sent by the network-side device. The resource configuration information includes the time-domain resource allocation (TDRA) field of the downlink control information (DCI) and the configuration of the physical uplink control channel (PUSCH) TDRA table to indicate the transmission time length of the PUSCH transport block (TB) processing.

[0136] In this embodiment, the resource configuration information includes a DCI TDRA field (i.e., DCI 0_X TDRA field) and a PUSCH TDRA table, which are used to indicate the transmission time length of PUSCH TB processing. Since the PUSCH TDRA table, which is not associated with TB processing, already has the start position, length flag value SLIV, and repeated transmission number information, by reusing the DCI TDRA field and configuring the PUSCH TDRA table, the transmission time length of TB processing can be flexibly configured, avoiding the increase of DCI overhead.

[0137] In some embodiments, the resource configuration information further includes at least one or more of the following:

[0138] Semi-static indication of multi-slot PUSCH TB processing switch;

[0139] A threshold for TB is used to indicate that when the number of bits in TB is greater than the threshold, multi-slot TB processing is not triggered, using a PUSCH TDRA table not associated with TB processing. When the number of bits in TB is less than the threshold, multi-slot TB processing is triggered, using a PUSCH TDRA table associated with TB processing.

[0140] By configuring a threshold for the size of a TB, repeated transmission or multi-slot TB processing can be triggered. When the number of bits in a TB is less than the threshold, encoding the sum of one or more time slot bits as a large TB yields a greater coding gain. The network side, such as the base station, uses a PUSCH TDRA table associated with TB processing. When the number of bits in a TB is greater than the threshold, the TB naturally needs to be divided into several CBs for multi-slot transmission. The gain from multi-slot TB processing is smaller, and the base station uses a PUSCH TDRA table not associated with TB processing, namely PUSCH-TimeDomainResourceAllocationList.

[0141] By setting a TB size threshold, the network side, such as the base station, can adaptively trigger the use of PUSCH retransmission or multi-slot TB processing to achieve better coverage performance.

[0142] In some embodiments, when the number of bits in a TB is less than a threshold, the configured number of repetitions can be considered as the number of time slots carrying the TB.

[0143] In some embodiments, the PUSCH TDRA table includes a PUSCH mapping type, a PUSCH slot offset K2, a transmission start symbol S, a number of symbols transmitted per slot L, and a number of TB processing slots N, indicating that PUSCH transmission starts from the slot with a slot offset of K2, and TB processing is performed for N consecutive uplink slots, with each slot occupying the S to S+L symbols.

[0144] In some embodiments, the L symbols in each time slot are resources or units carrying TB.

[0145] In some embodiments, the PUSCH TDRA table includes PUSCH mapping type, PUSCH slot offset K2, transmission start symbol S, and transmission symbol number L, indicating that the transmission starts from the Sth symbol of the PUSCH with slot offset K2 scheduled by DCI, and performs TB processing on L consecutive available uplink symbols.

[0146] In some embodiments, L transmission symbols represent resources or units that transmit TB.

[0147] In some embodiments, the PUSCH TDRA table includes a PUSCH mapping type, a PUSCH slot offset K2, a transmission start symbol S, a number of transmission symbols L, and a number of TB processing slots N, indicating that PUSCH transmission starts from the slot with a slot offset of K2, and TB processing is performed for N consecutive uplink slots.

[0148] In some embodiments, L symbols represent resources or units that carry TB.

[0149] In some embodiments, N*L symbols represent resources carrying TB.

[0150] In some embodiments, the available resources included in the time-domain resources indicated by the resource configuration information are used to determine the size of the transport block.

[0151] In some embodiments,

[0152] The available resources are at least one or more of the following:

[0153] The available resources are those that do not conflict with the downlink symbols or time slot resources configured in a semi-static manner;

[0154] The available resources do not conflict with the downlink symbol or the variable flexible symbol indicated by the Slot Format Indicator (SFI);

[0155] The available resources do not conflict with the downlink symbols and flexible symbols in the semi-statically configured time slots, especially in the case of uplink symbols in special subframes;

[0156] The available resources are uplink symbols in the semi-statically configured time slot resources, specifically for uplink symbols in special subframes.

[0157] The above method can be used to determine the validity of indicated resources and resolve conflicts with other dynamic indications. Based on the determination of resource validity, it can better adapt to the situation in TDD (Time Division Duplex) where only some uplink symbols are available in special subframes.

[0158] The technical solution of the present invention will be further explained and illustrated below with reference to specific embodiments.

[0159] Example 1:

[0160] In this embodiment, the TB size threshold is N. thresh Assume N threshThe time domain resource allocation is performed using the PUSCH TDRA table associated with TB processing when the number of bits in a TB is less than or equal to 8000 bits. When the number of bits in a TB is greater than 8000 bits, the TB processing function is turned off, and the time domain resource allocation is performed using the PUSCH TDRA table not associated with TB processing.

[0161] Example 2:

[0162] When higher-layer signaling indicates that multi-slot PUSCH TB processing is disabled, the DCI 0_X TDRA field can use the time-domain resource allocation table configured by higher-layer signaling for resource allocation.

[0163] When higher-layer signaling indicates that multi-slot PUSCH TB processing is enabled and PUSCH repetition is disabled, the bits of the DCI 0_XTDRA field are mapped to the row index of the PUSCH TDRA table associated with TB processing. The PUSCH TDRA table associated with TB processing has two configuration methods:

[0164] As shown in Table 1, each row index indicates the specific PUSCH mapping type, PUSCH slot offset K2, transmission start symbol S, number of symbols transmitted per slot L, and number of TB processing slots. The first row indicates that PUSCH transmission starts from the slot with slot offset K2, and TB processing is performed in 2 uplink slots, with each slot occupying symbols 0 to 13.

[0165] Table 1 PUSCH TDRA table

[0166]

[0167]

[0168] As shown in Table 2, each row index indicates the specific PUSCH mapping type, PUSCH slot offset K2, transmission start symbol S, and number of transmission symbols L. The first row indicates that PUSCH transmission starts from the slot with slot offset K2, and TB processing is performed on the 0th symbol of that slot for 32 consecutive available uplink symbols.

[0169] Table 2 PUSCH TDRA table

[0170]

[0171]

[0172] Example 3:

[0173] The base station instructs the UE (terminal) to perform multi-timeslot transmission of the same TB in 3 time slots, such as Figure 3 As shown. The downlink and uplink symbols in the first time slot X are configured based on RRC (Radio Resource Control) signaling. Therefore, the number of symbols the UE uses to calculate the TB does not include the downlink and flexible symbols in the shown X time slot; only the semi-statically configured uplink symbols are considered for calculating the TB size. Simultaneously, the resources of the two subsequently indicated uplink slots are also considered.

[0174] Example 4:

[0175] The base station indication start symbol is S=10, length L=14, and repetition count or time slot number = 3. Then, as follows... Figure 4 The 22 uplink symbols shown (comprising three symbol sets: symbol set #1, symbol set #2, and symbol set #3) are used for a TB transmission. When calculating the TB size, the indicated 22 symbols are considered, except for the third symbol set (#3), which is not considered in determining or identifying the TB size because the subsequent 10 symbols conflict with the downlink symbols in the semi-static configuration of the next time slot.

[0176] This invention also provides a resource indication device, applied to network-side devices, such as... Figure 5 As shown, it includes a transceiver 21 and a processor 22.

[0177] The transceiver 21 is used to send resource configuration information to the terminal. The resource configuration information includes the time domain resource allocation (TDRA) field of the downlink control information (DCI) and the configuration physical uplink control channel (PUSCH) TDRA table to indicate the transmission time length of the PUSCH transport block (TB) processing.

[0178] In this embodiment, the resource configuration information includes a DCI TDRA field (i.e., DCI 0_X TDRA field) and a PUSCH TDRA table, which are used to indicate the transmission time length of PUSCH TB processing. Since the PUSCH TDRA table, which is not associated with TB processing, already has the start position, length flag value SLIV, and repeated transmission number information, by reusing the DCI TDRA field and configuring the PUSCH TDRA table, the transmission time length of TB processing can be flexibly configured, avoiding the increase of DCI overhead.

[0179] In some embodiments, the resource configuration information further includes at least one or more of the following:

[0180] Semi-static indication of multi-slot PUSCH TB processing switch;

[0181] A threshold for TB is used to indicate that when the number of bits in TB is greater than the threshold, multi-slot TB processing is not triggered, using a PUSCH TDRA table not associated with TB processing. When the number of bits in TB is less than the threshold, multi-slot TB processing is triggered, using a PUSCH TDRA table associated with TB processing.

[0182] By configuring a threshold for the size of a TB, repeated transmission or multi-slot TB processing can be triggered. When the number of bits in a TB is less than the threshold, encoding the sum of one or more time slot bits as a large TB yields a greater coding gain. The network side, such as the base station, uses a PUSCH TDRA table associated with TB processing. When the number of bits in a TB is greater than the threshold, the TB naturally needs to be divided into several CBs for multi-slot transmission. The gain from multi-slot TB processing is smaller, and the base station uses a PUSCH TDRA table not associated with TB processing, namely PUSCH-TimeDomainResourceAllocationList.

[0183] By setting a TB size threshold, the network side, such as the base station, can adaptively trigger the use of PUSCH retransmission or multi-slot TB processing to achieve better coverage performance.

[0184] In some embodiments, when the number of bits in a TB is less than a threshold, the configured number of repetitions can be considered as the number of time slots carrying the TB.

[0185] In some embodiments, the PUSCH TDRA table includes a PUSCH mapping type, a PUSCH slot offset K2, a transmission start symbol S, a number of symbols transmitted per slot L, and a number of TB processing slots N, indicating that PUSCH transmission starts from the slot with a slot offset of K2, and TB processing is performed for N consecutive uplink slots, with each slot occupying the S to S+L symbols.

[0186] In some embodiments, the L symbols in each time slot are resources or units carrying TB.

[0187] In some embodiments, the PUSCH TDRA table includes PUSCH mapping type, PUSCH slot offset K2, transmission start symbol S, and transmission symbol number L, indicating that the transmission starts from the Sth symbol of the PUSCH with slot offset K2 scheduled by DCI, and performs TB processing on L consecutive available uplink symbols.

[0188] In some embodiments, L transmission symbols represent resources or units that transmit TB.

[0189] In some embodiments, the PUSCH TDRA table includes a PUSCH mapping type, a PUSCH slot offset K2, a transmission start symbol S, a number of transmission symbols L, and a number of TB processing slots N, indicating that PUSCH transmission starts from the slot with a slot offset of K2, and TB processing is performed for N consecutive uplink slots.

[0198] The available resources are uplink symbols in the semi-statically configured time slot resources, specifically for uplink symbols in special subframes.

[0199] The above method can be used to determine the validity of indicated resources and resolve conflicts with other dynamic indications. Based on the determination of resource validity, it can better adapt to the situation in TDD (Time Division Duplex) where only some uplink symbols are available in special subframes.
