Method and apparatus for resource allocation in wireless communication systems

摘要

Systems and methodologies are described that facilitate resource allocation and management in a wireless communication system. As described herein, a resource grid structure can be utilized to allocate resources for respective users corresponding to a given channel (e.g., a Physical Uplink Control Channel (PUCCH)). The resource grid can be constructed using one or more cyclic shifts and a set of four orthogonal covers to provide improved efficiency in resource usage. Further, slots in the resource grid can be allocated to respective users based on user indexes via one or more resource allocation functions. For example, a resource allocation function can step along a first orthogonal cover at increasing cyclic shifts, alternate between second and fourth orthogonal covers at increasing cyclic shifts upon exhaustion of the first orthogonal cover, and step through a third orthogonal cover at increasing cyclic shifts upon exhaustion of the second and fourth orthogonal covers.

1. A method for resource allocation in a wireless communication system, comprising:
identifying, by an apparatus, a set of acknowledgement (ACK)/negative acknowledgement (NACK) resources, wherein the set of ACK/NACK resources corresponds to a resource block comprising a plurality of data symbols and a plurality of demodulation reference signal (DM-RS) symbols; generating a resource grid corresponding to the set of ACK/NACK resources, wherein the resource grid has a first dimension corresponding to one or more cyclic shifts and a second dimension corresponding to a plurality of orthogonal covers, wherein the orthogonal covers correspond to orthogonal sequences used for transmission over the plurality of data symbols; and multiplexing one or more users onto the identified set of ACK/NACK resources at least in part by allocating resources corresponding to respective positions in the resource grid to respective users in the one or more users.
