摘要： Systems and methodologies are described that facilitate conveying decoding statuses in a wireless communication environment. A UE can transmit a plurality of codewords as part of an uplink multiple-input multiple-output (MIMO) transmission to a base station. The base station can receive and attempt to decode the plurality of codewords. Further, decoding statuses for the plurality of codewords can be determined. Moreover, the decoding statuses for the plurality of codewords can be signaled to the UE. For example, the decoding statuses for the plurality of codewords can be conveyed via a single PHICH. According to another example, multiple PHICHs can convey the decoding statuses. Pursuant to a further example, the decoding statuses can be conveyed at least in part via a PDCCH.

摘要： System(s) and method(s) are provided for inter-cell power control in the presence of fractional frequency reuse in a wireless communication system. Transmission power control of a terminal (210); and ensuing inter-cell interference mitigation, is accomplished by receiving load indicators (23Oi) from non-serving sectors (246i), decoding those load indicators corresponding to the non-serving sectors that operate in the same frequency bands as the terminal, and adjusting the transmission power according to the states of the decoded load indicators in conjunction with the associated non-serving sector forward link signal-to-interference and-noise ratio at the terminal. The states of the load indicators reflect magnitudes of interference metrics with respect to threshold values. Load indicators can also be conveyed by the non-serving sector to a base station (260) serving the terminal through a backhaul (250) communication, and said base station can schedule an adjusted transmission power for the terminal.

摘要： 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).

摘要： Systems and methodologies are described that facilitate allocation of uplink acknowledgement (ACK) resources for a wireless communication system. Various aspects described herein facilitate explicit creation and transmission of a bundled assignment of downlink communication resources and uplink resources for ACK transmission, thereby facilitating overhead-efficient ACK allocation for users that can communicate pursuant to a persistent resource assignment without requiring scheduling information from an associated control channel. Additionally, indexing schemes for uplink ACK resources are provided herein to facilitate ACK allocation for systems in which both scheduled and persistent users can communicate at a common transmission time interval (TTI).
