Abstract

The present invention discloses a retransmission method, device, apparatus and storage medium, including: the network side indicates the time domain resource allocation for the terminal to transmit PUSCH, where the PUSCH time domain resources include at least two time slots or two time domain resource granularities, and the time domain resources allocated within different time slots or time domain resource granularities are not completely the same; wherein, the PUSCH time domain resources are used for the terminal to retransmit the same data. The terminal receives the time domain resource allocation of PUSCH indicated by the network side and retransmits the same data on the PUSCH time domain resources. By adopting the present invention, the terminal can determine different PUSCH symbol allocations in different time slots for the terminal to retransmit the same data. Therefore, for a terminal that only supports transmitting one PUSCH within one time slot, the UL symbols in special time slots can be fully utilized for PUSCH transmission through this solution, which can be used to improve the coverage and reliability of PUSCH.

Description

Technical Field

[0001] The present invention relates to the field of wireless communication technology, and particularly to a retransmission method, device, apparatus and storage medium. Background Art

[0002] NR (New Radio) currently supports two types of PUSCH repetition, namely PUSCH repetition type A (PUSCH: Physical Uplink Shared Channel) and PUSCH repetition type B.

[0003] Among them, PUSCH repetition type A is slot-based PUSCH repetition, and the supported PUSCH mapping type can be type A or type B. The terminal transmits the same TB (Transport Block) on K consecutive slots, and the time-domain resource allocation method (i.e., the occupied symbol position) within each slot is exactly the same.

[0004] Among them, PUSCH repetition type B is mini-slot-based PUSCH repetition, and the supported PUSCH mapping type can only be type B. PUSCH repetition type B can transmit multiple PUSCHs within one slot.

[0005] The disadvantages of the prior art are as follows: In the current retransmission scheme, the time-domain resource allocation for each PUSCH transmission is exactly the same (same symbol length), and it is impossible to transmit PUSCHs with different symbol lengths in different slots or time-domain resource granularities, and it is impossible to make full use of the different uplink and downlink symbol number configurations in different slots in the TDD frame structure, and it is impossible to transmit in each slot with uplink symbols.

Since the terminal can determine different PUSCH symbol allocations in different time slots for the terminal to repeat the transmission of the same data, the different uplink and downlink symbol number configurations in different time slots in the TDD frame structure can be fully utilized. For example, there are only 4 uplink symbols in the special time slot, and there are 14 uplink symbols in the uplink time slot. Through this solution, the UL symbols in the special time slot can be fully utilized for the transmission of PUSCH. For example, the terminal can use 4 uplink symbols to transmit PUSCH once in the special time slot, and can use all 14 symbols to transmit PUSCH again in the uplink time slot, which can be used to improve the coverage and reliability of PUSCH. BRIEF DESCRIPTION OF THE DRAWINGS

[0133] The drawings described herein are used to provide a further understanding of the present invention, and constitute a part of the present invention. The schematic embodiments of the present invention and their descriptions are used to explain the present invention, and do not constitute an improper limitation to the present invention. In the drawings:

[0134] Figure 1 It is a schematic flowchart of the repeated transmission method on the network side in the embodiment of the present invention;

[0135] Figure 2 It is a schematic flowchart of the repeated transmission method on the terminal side in the embodiment of the present invention;

[0136] Figure 3 It is a schematic diagram of the base station structure in the embodiment of the present invention;

[0137] Figure 4 It is a schematic diagram of the UE structure in the embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0138] The inventor noticed during the invention process:

[0139] In the current TDD (Time Division Duplex) frame structure, there are special time slots used for the uplink and downlink conversion of TDD. For example, DDDDDDDSUU, where D represents the downlink time slot, U represents the uplink time slot, and S represents the special time slot. The ratio of the S time slot is D:S:U = 6:4:4.

[0140] For cell-edge users, PUSCH repetition is a good way to improve coverage. However, according to the current PUSCH repetition type A method, the terminal repeats the transmission of PUSCH in multiple time slots, and the PUSCH symbol resource allocation in each time slot must be exactly the same. That is, it can only transmit more symbols on two Us. For example, each transmits a PUSCH with 14 symbols. If you want to use the S time slot, since the number of PUSCH symbols in each time slot must be the same, then at most 8 symbols of PUSCH can be transmitted on one S and two Us respectively. This transmission method cannot fully utilize the 14 uplink symbols of the U time slot.

[0141] Another implementation method is to use the PUSCH repetition type B method. Assuming the number of symbols repeated each time is 4, then one PUSCH can be transmitted in one S time slot, and 3 PUSCHs can be transmitted in the following two Us respectively. However, PUSCH repetition type B requires the terminal to support the transmission of multiple PUSCHs in one time slot. This UE (User Equipment) capability is optional and not supported by all UEs.

[0142] Therefore, how to achieve PUSCH repeated transmission in both the S time slot and the U time slot for a terminal that only supports the ability to transmit one PUSCH in one time slot, and use as many symbols as possible. For example, transmit 8 symbols in the S time slot and 14 symbols in the U time slot. This is a problem to be solved.

[0143] Based on this, in the embodiments of the present invention, a PUSCH repeated transmission scheme is provided. For one TB, it can achieve different numbers of symbols in the time domain resource allocation on different time slots. Specifically, the scheme can achieve different numbers of symbols in the time domain resource allocation on different time slots for one TB. The terminal can transmit the same TB on as many time slots as possible to improve the coverage performance of PUSCH.

[0144] The following will describe the specific embodiments of the present invention with reference to the accompanying drawings.

[0145] In the description process, the implementation will be described separately from the UE side and the base station side, and then examples of their combined implementation will also be given to better understand the implementation of the solutions given in the embodiments of the present invention. Such a description method does not mean that the two must be implemented in cooperation or must be implemented separately. In fact, when the UE and the base station are implemented separately, they also solve the problems on the UE side and the base station side respectively, and when the two are used in combination, better technical effects will be obtained.

The time-domain resources defined by the row index are used for the terminal to determine the time-domain resources used for transmitting the PUSCH.

Among them, one row index corresponds to two SLIV values, or one row index corresponds to two sets of configurations of the starting symbol and the number of symbols;

[0156] The terminal transmits the PUSCH on the time-domain resources defined according to the row index.

[0157] The following describes a scheme where one indicated time-domain resource allocation row index corresponds to two SLIV values, or one row index corresponds to two sets of starting symbols and the number of symbols.

[0158] In implementation, the row index of the PUSCH time-domain resource allocation table used by the terminal indicated by the network side is indicated by the time-domain resource allocation information field carried by DCI (Downlink Control Indicator).

[0159] In implementation, the network side configures the usage conditions corresponding to the two SLIV values or the two sets of starting symbols and the number of symbols respectively through high-layer signaling.

[0160] Specifically, the behavior of the network side can be as follows:

[0161] The network side indicates the row index of the PUSCH time-domain resource allocation table used by the terminal through the time-domain resource allocation information field carried by DCI, where one row index corresponds to two SLIV (Start and length indicator value) values or corresponds to two sets of configurations of the starting symbol and the number of symbols.

[0162] The network side configures two SLIV values or two sets of starting symbols and the number of symbols in a PUSCH time-domain resource configuration information through high-layer signaling.

[0163] In implementation, it can further include:

[0164] The network side configures the usage conditions corresponding to the two SLIV values or the two sets of starting symbols and the number of symbols respectively through high-layer signaling;

[0165] Among them, the usage conditions include: use in full uplink time slots and / or non-full uplink time slots.

[0166] For the terminal side, it further includes:

[0167] Receiving the usage conditions corresponding to the two SLIV values or the two sets of starting symbols and the number of symbols configured by the network side. Among them, the usage conditions include: use in full uplink time slots and / or non-full uplink time slots;

[0168] Determine the SLIV value or the starting symbol and the number of symbols used within different time slots or time domain resource granularities according to the usage conditions.

[0169] Specifically, the network side configures the time slot configuration pattern or usage conditions corresponding to the two SLIV values or the two sets of values of the starting symbol and the number of symbols through high-layer signaling. The usage conditions can be the time slot configuration pattern.

[0170] The time slot configuration pattern or usage conditions can be at least one of the following cases:

[0171] 1) Full uplink time slot;

[0172] 2) Non-full uplink time slot.

[0173] A full uplink time slot means that all symbols within this time slot are configured as uplink symbols; a non-full uplink time slot means that at least one of the symbols within this time slot is a downlink symbol or a flexible symbol.

[0174] For example, the network side configures one of the SLIV values or a set of values of the starting symbol and the number of symbols to correspond to a full uplink time slot, and the other SLIV value or a set of values of the starting symbol and the number of symbols to correspond to a non-full uplink time slot.

[0175] A full uplink time slot, for example, is a time slot where all are UL (uplink) symbols.

[0176] In implementation, it further includes:

[0177] The network side configures or indicates the repetition count of the terminal PUSCH through high-layer signaling or DCI.

[0178] Specifically, the network side configures or indicates the repetition count of the PUSCH through high-layer signaling or DCI.

[0179] For the terminal side, it can be as follows:

[0180] The terminal receives the DCI sent by the network side, and the time domain resource allocation information field carried in the DCI indicates the row index of the PUSCH time domain resource allocation table used by the terminal, where one row index corresponds to two SLIV values or corresponds to two sets of values of the starting symbol and the number of symbols.

[0181] The terminal receives the configuration or indication of the repetition count of the PUSCH from the network side through high-layer signaling or DCI.

[0182] The terminal determines the time domain resource allocation of the PUSCH according to different SLIV values or different values of the starting symbol and the number of symbols on different time slots, and repeats the transmission of the PUSCH on at least one time slot.

[0183] The terminal receives the usage conditions or time slot configuration patterns corresponding to the two SLIV values or two sets of start symbol and symbol quantity values respectively configured by the network side through high-layer signaling.

[0184] The usage conditions or time slot configuration patterns may be at least one of the following cases:

[0185] 1) All uplink time slots;

[0186] 2) Non-all uplink time slots.

[0187] The terminal determines which SLIV value or which set of start symbol and symbol quantity values to use to determine the time domain resource allocation of the PUSCH for this time slot or time domain resource granularity according to the configuration pattern or usage condition of the above time slot.

[0188] It may be configured through high-layer signaling. For example, when the SLIV value is n, it corresponds to all uplink time slots, and when the SLIV value is m, it corresponds to non-all uplink time slots.

[0189] For example, when the start symbol is n1 and the symbol quantity is m1, it corresponds to all uplink time slots; when the start symbol is n2 and the symbol quantity is m2, it corresponds to non-all uplink time slots.

[0190] In implementation, the SLIV value or start symbol and symbol quantity used within different time slots or time domain resource granularities are determined according to one or a combination of the following symbol quantities:

[0191] The number of uplink symbols configured within the time slot or time domain resource granularity;

[0192] The number of non-downlink symbols configured within the time slot or time domain resource granularity;

[0193] The number of symbols capable of transmitting PUSCH within the time slot or time domain resource granularity.

[0194] Specifically, the terminal determines which SLIV value or which set of start symbol and symbol quantity values to use to determine the time domain resource allocation of the PUSCH for this time slot or time domain resource granularity according to the symbol configuration situation within the time slot or time domain resource granularity.

[0195] Among them, the symbol configuration situation within the time slot or time domain resource granularity may be at least one of the following cases:

[0196] 1) The number of uplink symbols configured within the time slot or time domain resource granularity;

[0197] 2) The number of non-downlink symbols configured within the time slot or time domain resource granularity;

[0198] 3) The number of symbols capable of transmitting PUSCH within the time slot or time domain resource granularity.

[0199] In implementation, when determining the SLIV value or the starting symbol and the number of symbols used within the current time slot or time domain resource granularity, select the SLIV value with the longest allocated number of symbols as the SLIV value, or select the value of the longest number of symbols as the number of symbols allocated for PUSCH.

[0200] Specifically, when the terminal meets the symbol configuration of the current time slot or time domain resource granularity, select the SLIV value with the longest allocated number of symbols as the SLIV value of the current time slot, or select the value of the longest number of symbols as the number of symbols allocated for PUSCH.

[0201] The terminal can automatically match the available SILV value according to the symbol configuration within the current time slot or time domain resource granularity.

[0202] In one embodiment, the symbol length corresponding to one SLIV value is 10, and the symbol length corresponding to another SLIV value is 4. The number of uplink symbols in time slot n is 14, then select the SLIV value with the corresponding symbol length of 10. The number of uplink symbols in time slot m is 5, then select the SLIV value with the corresponding symbol length of 4.

[0203] The following describes the solution by configuring the first parameter.

[0204] The network side indicates the first parameter to the terminal and the row index of the PUSCH time domain resource allocation table used by the terminal, where the first parameter is used to determine the symbol length of the allocated PUSCH time domain resource, and the time domain resource defined by the row index and the first parameter are used for the terminal to determine the time domain resource used for transmitting the PUSCH.

[0205] For the terminal side, the terminal receives the first parameter indicated by the network side and the row index of the PUSCH time domain resource allocation table used by the terminal, where the first parameter is used to determine the symbol length of the allocated PUSCH time domain resource;

[0206] The terminal transmits the PUSCH on the time domain resource determined according to the time domain resource defined by the row index and / or the first parameter.

[0207] The first parameter can be indicated by DCI or high-layer signaling; the row index of the PUSCH time domain resource allocation table can be indicated in DCI.

[0208] In implementation, the first parameter can be a value less than 1, which is used to calculate the length of PUSCH symbol allocation.

[0209] In implementation, the network side indicates the first parameter to the terminal by DCI or high-layer signaling.

[0210] In implementation, the row index of the PUSCH time-domain resource allocation table of the terminal is indicated by the time-domain resource allocation information field carried by DCI.

[0211] Specifically, for the network side, it can be as follows:

[0212] The network side indicates the first parameter of the PUSCH time-domain resource allocation of the terminal through DCI or high-layer signaling.

[0213] The network side configures the first parameter in a PUSCH time-domain resource configuration information through high-layer signaling.

[0214] Alternatively, the first parameter configured by the high-layer signaling is applicable to all PUSCH time-domain resource configuration information.

[0215] The network side indicates the row index of the PUSCH time-domain resource allocation table used by the terminal through the time-domain resource allocation information field carried by DCI.

[0216] The first parameter can be specifically shown as the scaling factor in the bold part of the following table:

[0217]

[0218]

[0219] In implementation, it further includes:

[0220] The network side configures or indicates the repetition transmission times of the PUSCH of the terminal through high-layer signaling or DCI.

[0221] For the terminal side, it can further include:

[0222] The terminal receives the repetition transmission times of the PUSCH indicated by the network side through DCI or configured by high-layer signaling.

[0223] Specifically, the network side configures or indicates the repetition times of the PUSCH through high-layer signaling or DCI.

[0224] For the terminal side, it can be as follows:

[0225] The terminal receives the DCI and / or high-layer signaling sent by the network side. The time-domain resource allocation information field carried in the DCI indicates the row index of the PUSCH time-domain resource allocation table used by the terminal, and the first parameter is carried in the DCI or high-layer signaling.

[0226] The terminal determines the time-domain resource allocation of the PUSCH according to the row index of the PUSCH time-domain resource allocation table used as indicated and / or the first parameter in different time slots, and repeats the transmission of the PUSCH in at least one time slot.

[0227] In implementation, it further includes: the network side configures or indicates the repetition transmission times of the terminal's PUSCH through high-layer signaling or DCI.

[0228] Specifically, the terminal receives the repetition times of the PUSCH configured or indicated by the network side through high-layer signaling or DCI.

[0229] In implementation, the terminal determines whether to use the first parameter and the row index of the PUSCH time-domain resource allocation table to determine the time-domain resources used for transmitting the PUSCH within a time slot or time-domain resource granularity, or only use the row index of the PUSCH time-domain resource allocation table to determine the time-domain resources used for transmitting the PUSCH within a time slot or time-domain resource granularity, according to one or a combination of the following symbol quantities:

[0230] The number of uplink symbols configured within a time slot or time-domain resource granularity;

[0231] The number of non-downlink symbols configured within a time slot or time-domain resource granularity;

[0232] The number of symbols within a time slot or time-domain resource granularity that can transmit the PUSCH.

[0233] The determination method of the number of symbols allocated for the PUSCH is described below.

[0234] The terminal determines whether to jointly determine the time-domain resource allocation of the PUSCH in this time slot or time-domain resource granularity according to the first parameter and the row index of the PUSCH time-domain resource allocation table, based on the symbol configuration in the time slot or time-domain resource granularity.

[0235] Among them, the symbol configuration in the time slot or time-domain resource granularity can be at least one of the following situations:

[0236] 1) The number of uplink symbols configured within a time slot or time-domain resource granularity;

[0237] 2) The number of non-downlink symbols configured within a time slot or time-domain resource granularity;

[0238] 3) The number of symbols within a time slot or time-domain resource granularity that can transmit the PUSCH.

[0239] For example, if the number of symbols L determined according to the row index of the PUSCH time-domain resource allocation table * the first parameter satisfies the symbol configuration condition of the above time slot or time-domain resource granularity within the current time slot or time-domain resource granularity, but the number of symbols L determined according to the row index of the PUSCH time-domain resource allocation table does not satisfy the symbol configuration condition of the above time slot or time-domain resource granularity within the current time slot or time-domain resource granularity, the terminal selects L * the first parameter as the number of symbols allocated for the PUSCH in this time slot or time-domain resource granularity.

[0240] If the number of symbols L determined according to the row index of the PUSCH time-domain resource allocation table meets the symbol configuration condition within the current time slot or time-domain resource granularity, the terminal selects L as the number of symbols allocated for the PUSCH in this time slot or time-domain resource granularity.

[0241] The terminal knows the symbol configuration of the current time slot or time-domain resource granularity and also knows the row index of the PUSCH time-domain resource configuration. When determining whether to use the first parameter, it can be based on the current symbol configuration. For example, if the row index of the current PUSCH time-domain resource configuration indicates that 14 symbols are all used as PUSCH transmission symbols, the first parameter is 0.5, and time slot n is a full uplink time slot, then a PUSCH with 14 symbols can be transmitted within this time slot. If there are only 10 UL symbols in time slot n + 1, then only a PUSCH with 14 * 0.5 = 7 symbols can be transmitted.

[0242] In implementation, when the terminal uses the first parameter and the row index of the PUSCH time-domain resource allocation table to determine the time-domain resources used for transmitting PUSCH within a time slot or time-domain resource granularity, the starting symbol position of the PUSCH is the first symbol available for PUSCH transmission within the time slot or time-domain resource granularity, or the last symbol of the PUSCH is the last symbol within the time slot or time-domain resource granularity.

[0243] Specifically, the determination method for the starting symbol of the PUSCH can be as follows:

[0244] When the terminal selects L * the first parameter as the number of symbols allocated for the PUSCH in this time slot or time-domain resource granularity, the terminal configures the starting symbol position of the PUSCH in this time slot or time-domain resource granularity according to the protocol predefinition or high-layer signaling as the first symbol available for PUSCH transmission, or the last symbol of the PUSCH is the last symbol within the time slot or time-domain resource granularity.
