Embodiment 1

[0212] like Figure 2 to Figure 3 As shown, the base station configures two carriers for the user terminal, wherein the subcarrier spacing of carrier 1 is configured as 15kHz, and the subcarrier spacing of carrier 2 is configured as 60kHz, and carrier 1 is the transmission carrier of PUCCH, and the base station configures carrier 2 to use Multi-slot PUSCH transmission with a repetition number of 4. When there is PUCCH transmission in slot n of carrier 1, if at the same time the base station schedules a multi-slot PUSCH in slots 4n+2, 4n+3, 4n+4, 4n+5 of carrier 2, then,

[0213] If you use the above method one, such as figure 2 As shown, the UCI carried by the PUCCH in carrier 1 is transferred to the time slots 4n+2, 4n+3, 4n+4, and 4n+5 of carrier 2 for multiplex transmission on the PUSCH, and the PUCCH is discarded;

[0214] If you use the second method above, such as image 3 As shown, since there is no multi-slot PUSCH whose start position is earlier than or equal to t...

Embodiment 2

[0220] like Figure 4 As shown, the base station configures four carriers for the user terminal, wherein the subcarrier spacing of carrier 1 is configured as 15 kHz, the subcarrier spacing of carrier 2, carrier 3 and carrier 4 are all configured at 60 kHz, and carrier 1 is the transmission carrier of PUCCH. The base station configures carrier 2 and carrier 3 to use multi-slot PUSCH transmission with a repetition number of 4, and carrier 4 to use single-slot PUSCH transmission. When there is PUCCH transmission in slot n of carrier 1, if at the same time the base station schedules a multi-slot PUSCH in slots 4n+2, 4n+3, 4n+4, 4n+5 of carrier 2, A multi-slot PUSCH is scheduled in time slots 4n, 4n+1, 4n+2, and 4n+3, and a single-slot PUSCH is scheduled in time slots 4n, 4n+1, 4n+2, and 4n+3 of carrier 4 , then the user terminal preferentially selects the PUSCH for single-slot transmission, and multiplexes the UCI on the PUSCH in the time slot 4n of the carrier 4 for transmission...

Embodiment 3

[0223] like Figure 5 to Figure 8 As shown, the base station configures two carriers for the user terminal, wherein, the subcarrier spacing of carrier 1 is configured as 15kHz, the subcarrier spacing of carrier 2 is configured as 60kHz, carrier 1 is the transmission carrier of PUCCH, and the base station configures carrier 2 to use repeated The number of multi-slot PUSCH transmissions is 4. When there is PUCCH transmission in slot n and slot n+1 of carrier 1, if at the same time the base station schedules multi-slot PUSCH transmission of slots 4n+2, 4n+3, 4n+4, 4n+5 on carrier 2 , there are several different results as follows:

[0224] Using the above rules for a while, such as Figure 5 As shown, the multi-slot PUSCH transmission on carrier 2 is discarded, and only the PUCCH in slot n and slot n+1 of carrier 1 is transmitted;

[0225] When using rule 2 above, if Image 6 As shown, the UCI information carried by the first PUCCH is placed on the multi-slot PUSCH for multip...

Abstract

The embodiment of the invention provides an uplink control information UCI transmission method, a user terminal and a base station. The method is applied to a user terminal, and comprises the following steps: determining whether a multi-time-slot PUSCH which is at least partially overlapped with a single-time-slot PUCCH in time exists for the single-time-slot PUCCH; if the multi-time-slot PUSCH which is at least partially overlapped with the single-time-slot PUCCH in time exists, transferring the UCI carried by the single-time-slot PUCCH to each time slot of the multi-time-slot PUSCH for transmission, and discarding the single-time-slot PUCCH; or, if the multi-time-slot PUSCH which is at least partially overlapped with the single-time-slot PUCCH in time exists, transmitting the UCI borne by the single-time-slot PUCCH in the single-time-slot PUCCH, and discarding the time slot which is overlapped with the single-time-slot PUCCH in time in the multi-time-slot PUSCH. Thus, the embodimentsof the present invention can effectively ensure the transmission performance of the UCI on the premise of ensuring that no uplink channel conflict occurs.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a UCI transmission method, user terminal and base station. Background technique [0002] With the development and change of mobile communication service requirements, many organizations such as the International Telecommunication Union (International Telecommunication Union, ITU) have begun to study a new wireless communication system, that is, a 5G New Radio (New Radio, NR) communication system. [0003] For the same user terminal, in order to avoid excessive peak-to-average power ratio (Peak to Average Power Ratio, PARR), the 5G NR communication system currently does not support simultaneous transmission of uplink channels or signals. Therefore, when the resources of uplink channels or signals When overlapping, specific information multiplexing or discarding transmission rules need to be defined to ensure that the user terminal only transmits one uplink channel o...
