Abstract

Systems and methodologies are described that facilitate improved resource management in a wireless communication system. As described herein, supergroups can be formed from groups of Physical Hybrid Automatic Repeat Request Channels (PHICHs) such that respective PHICH supergroups are multiplexed onto respective non-overlapping resource element subsets, thereby improving resource usage efficiency for the extended cyclic prefix case and limited numbers of transmit antennas. In one example described herein, even-indexed PHICH groups are mapped to a selected subset of resource elements in a group while odd-indexed PHICH groups are mapped to the remaining resource elements in the group. This mapping can be performed by modifying orthogonal sequences associated with the PHICH groups and/or by performing resource mapping in different manners for respective PHICH supergroups. Upon receiving a transmission of mapped PHICH information, a receiving entity can leverage knowledge of the mapping to decode transmitted PHICH information using the proper resource subset(s).

Description

[0001] cross reference [0002] This patent application claims priority to U.S. Provisional Application No. 61 / 038,875, filed March 24, 2008, entitled "METHODS ANDAPPARATUS FOR TRANSMIT DIVERSITY SCHEMES IN LTE," which is hereby incorporated by reference in its entirety. technical field [0003] In general, the present invention relates to wireless communication, and in particular, to techniques for resource management in wireless communication systems. Background technique [0004] Wireless communication systems are widely used to provide various communication services; for example, voice, video, packet data, broadcast and messaging services may be provided via such wireless communication systems. These systems may be multiple-access systems, which are capable of supporting communication for multiple users by sharing available system resources. Examples of such multiple-access systems include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA...
