Patent ID: 8379507

Claim:
A base station for use in a wireless network, comprising: a processor operable to execute instructions, coupled to a memory containing instructions for the processor; a radio receiver and a transmitter coupled to the processor; wherein the transmitter is operable to: transmit an SRI cycle period for use by user equipment (UE) within a cell; transmit a specific SRI subframe offset to a first UE; transmit an index value n to the first UE; and wherein the specific SRI subframe offset and the index value n enable the first UE to determine a unique combination of cyclic shift, reference signal (RS) orthogonal cover, data orthogonal cover, and resource block number for the first UE to use as a unique physical resource for an SRI in the physical uplink control channel (PUCCH); wherein the SRI is transmitted on a two-state SR channel.
