METHOD AND SYSTEM FOR MAPPING HARQ-ACK BITS

摘要

A subscriber station is provided. The subscriber station includes a transmit path circuitry to transmit uplink control information (UCI) in a subframe comprising one or more resource blocks, each resource block comprising S SC-FDM symbols. Each of the S symbols comprises N virtual subcarriers, and each subcarrier of each symbol comprises a resource element. The subscriber station also includes a UCI symbol allocator to allocate a first vector sequence of HARQ-ACK bits to a control region of each of four symbols of a resource block, the control region allocated for HARQ-ACK bits. The UCI symbol allocator also allocates 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. The control region of the fifth symbol can be allocated for rank information (RI) bits.
