Partitioning of frequency resources for transmission of control signals and data signals in SC-FDMA communication systems

摘要

A method for the partitioning frequency resources used in the transmission of control signals and data signals by user equipments in a communication system. The control signals and data signals are for periodic transmission and dynamic transmission. Also provided is an apparatus and method for user equipments to determine the first frequency unit available for the transmission of dynamic control signals, such as acknowledgement signals associated respective reception of data signals configured through a scheduling assignment by a serving Node B. The utilization of the operating bandwidth is maximized by avoiding fragmentation and facilitates the achievement of reception reliability targets particularly for control signals.

1. A method for a base station to allocate frequency resources for uplink transmission of user equipments (UEs) in a communication system, the method comprising:
allocating, by a processor of the base station, on each side of an operating bandwidth, a second frequency resource for an acknowledgement signal between a first frequency resource for a channel quality indication (CQI) signal having periodic transmission and a third frequency resource for transmission of a data signal; and allocating, by the processor, the third frequency resource between the second frequency resources, wherein the data signal is transmitted together with a reference signal mapped to a middle symbol position in a slot.
