Abstract:
1. A subscriber station comprising: a transmit path circuitry configured to transmit uplink control information (UCI) in a subframe comprising one or more resource blocks, each resource block comprising S single carrier frequency division multiplexing (SC-FDM) symbols, each of the S single carrier frequency division multiplexing (SC-FDM) symbols comprising N virtual subcarriers, and each virtual subcarrier of each symbol comprises a resource element; and a UCI symbol allocator configured to: allocate a first vector sequence of hybrid automatic-repeat-request acknowledgement (HARQ-ACK) bits to a control region of each of four symbols of a resource block, the control region allocated for HARQ-ACK bits, and allocate a second vector sequence of HARQ-ACK bits to a control region of a fifth symbol of the resource block when a condition is met, wherein the control region of the fifth symbol can be allocated for rank information (RI) bits.
