Method for determining uplink control channel scheduling unit, base station and user equipment
摘要
說明書
According to a rule, the base station and UE respectively derive the scheduling unit used by the PUCCH starting from the start scheduling unit, and mapping of the PUCCH in the derived scheduling unit. Specifically, the reserved scheduling unit and/or the unknown scheduling unit and/or the RACH scheduling unit after the start scheduling unit are excluded and the scheduling unit is selected from the uplink scheduling unit and the downlink scheduling unit. The downlink scheduling unit includes a downlink-only scheduling unit and a downlink-dominated scheduling unit, and the uplink scheduling unit includes an uplink-only scheduling unit and an uplink-dominated scheduling unit. If the selected scheduling unit is an uplink-dominated scheduling unit, the number of uplink symbols included in the uplink-dominated scheduling unit is required to satisfy a requirement, and if the selected scheduling unit is a downlink-dominated scheduling unit, the number of downlink symbols included in the downlink-dominated scheduling unit is required to satisfy a requirement.
In one carrier, a slot n is indicated as a start slot of the PUCCH. Assuming that the PUCCH is configured to span 3 slots and there are 4 uplink OFDM symbols in each slot to carry the PUCCH, the UE also needs to determine another 2 slots after the slot n to carry the PUCCH. In this embodiment, the base station and the UE determine remaining slots according to the following rule.
