The embodiments of the present disclosure provide a transmission method for improving PUCCH coverage performance, that is, a PUCCH repeat transmission scheme based on symbol level, where PUCCH repeat transmission can be flexibly configured through DCI, multiple PUCCH repeat transmissions can be supported in one slot, uplink symbol transmission in a special slot can be utilized, and discontinuous uplink symbol transmission in the same slot can be supported, so that uplink resource utilization rate is improved, PUCCH repeat transmission delay is reduced, and PUCCH coverage performance is further improved.
The following describes a transmission method for improving uplink coverage performance of a physical uplink control channel according to an embodiment of the present disclosure.
Fig. 4 is a diagram of some other embodiments of the transmission method for improving uplink coverage performance of a physical uplink control channel according to the present disclosure.
As shown in fig. 4, a DDDSU frame structure is taken as an example, where D is a downlink subframe or symbol, S is a feature subframe, and U is an uplink subframe or symbol. Slot 3(slot #3) is a special subframe, slot 4(slot # 4).
In S, for example, D: GP: U is 8:2:4, it is assumed that the number of repeatedly transmitted symbols is 4, the symbol start position is 10, and the number of times of PUCCH repeated transmission is 4. Symbols 8 and 9 of slot 3 are guard interval symbols, symbols 2 and 3 of slot 4 are unavailable symbols, and a bold frame represents PUCCH repetition (PUCCH repetition).
For the Nominal PUCCH repeated transmission scheme, repeated transmission can be carried out only once on slot # 4, and the rest UL symbols (uplink symbols) cannot be transmitted, so that the utilization rate of uplink resources is greatly reduced, and the repeated transmission performance of the PUCCH is seriously influenced.
For the Actual PUCCH repeat transmission scheme, uplink resources can be fully utilized, 4 times of repeat transmission can be completed in a short time, and the PUCCH repeat transmission delay is reduced. The advantages that exist are as follows:
first, uplink symbol transmission in a special slot is possible. For example, symbols 10-13 of slot 3, are transmitted for the first repetition (rep # 0).
And secondly, repeated transmission of the PUCCH can be carried out for multiple times in one time slot. For example: three PUCCH repetition transmissions may be performed in slot 4, specifically: symbols 0-1, 4-5 of slot 4 constitute a second repeat transmission (rep #1), symbols 6-9 of slot 4 constitute a third repeat transmission (rep #2), and symbols 10-13 of slot 4 constitute a fourth repeat transmission (rep # 3).
Thirdly, when the unavailable symbols exist, the PUCCH repeated transmission of the discontinuous symbols can be carried out. For example: symbols 0-1, 4-5 of slot 4 constitute a second repeat transmission (rep # 1).
