Abstract:
1. A physical uplink control channel (PUCCH) power control method, comprising: determining, by a user equipment (UE), a value of a power control parameter n performing, by the UE, power control on the PUCCH format 3 transmission based on the value of the n wherein the determining, by the UE, the power of the power control parameter n when a spatial bundling operation is employed, determining the n wherein the performing, by the UE, power control on the PUCCH format 3 based on the value of the n when the PUCCH format 3 transmission is employed in subframe i of serving cell c, putting the n wherein P CMAX,c (i) is a maximum transmit power of a serving cell c in subframe i, P O PUCCH is an open loop power control parameter, Δ F PUCCH (F) is a power offset associated with PUCCH format F, PL c is a downlink path loss in the serving cell c measured and calculated by the UE, Δ TxD (F′) is a transmission diversity power compensation set according to a different PUCCH format F′, and h(n CQI ,n HARQ ,n SR ) is a value based on the PUCCH format; when single Reed-Muller (RM) encoded PUCCH format 3 is employed and no transmission diversity is configured, when single RM encoded PUCCH format 3 is employed and transmission diversity is configured, or when dual RM encoded PUCCH format 3 is employed, wherein if a current subframe is configured as an SR transmission subframe, n SR =1; otherwise, n SR =0, n CQI is a number of bits of a channel quality indicator.
