Abstract: Apparatuses and methods are disclosed for managing discovery in wireless peer-to-peer networks. Various discovery procedures may be implemented by supporting a broadcast of a plurality of discovery signals spaced apart in time by silent periods from a peer node and changing the duration of at least one of the silent periods.

Abstract: Techniques for transmitting data with short-term interference mitigation in a wireless communication system are described. In one design, a first station (e.g., a base station or a terminal) may receive a message sent by a second station to request reduction of interference on at least one resource. In response to receiving the message, the first station may determine a first transmit power level to use for the at least one resource based on one or more factors such as a priority metric sent in the message, the buffer size at the first station, etc. The first station may send a power decision pilot on the at least one resource at a second transmit power level determined based on the first transmit power level.

Abstract: Techniques for transmitting data with short-term interference mitigation in a wireless communication system are described. In one design, a first station (e.g., a base station or a terminal) may send a first message to at least one interfering station to request reduction of interference on at least one resource. The first station may send the first message in anticipation of receiving data on the at least one resource. An interfering station may receive the first message from the first station and may reduce interference on the at least one resource by reducing its transmit power and/or by steering its power in a direction different from the first station. The first station may thereafter receive data from a second station on the at least one resource. The techniques may be used for data transmission on the forward and reverse links.

Abstract: Signaling-only access may be established with an access node (104) under certain circumstances such as, for example, upon determining that a node (102) is not authorized for data access at the access node (102). A node (104) that is not authorized for data access at an access node (104) may still be paged by the access node (104) through the use of signaling-only access. In this way, transmissions by the access node (104) may not interfere with the reception of pages at the node (302). A first node may be selected for providing paging (102) while a second node (106) is selected for access (304) under certain circumstances such as, for example, upon determining that the second node provides more desirable service than the first node.

Abstract: Providing for management of wireless communications in a heterogeneous wireless access point (AP) environment is described herein. By way of example, system data of an over-the-air message can be configured to include information identifying a distinct type of transmitting base station. In some aspects, the information can include an access type of the base station and/or a sector ID for distinguishing the base station among large numbers of other base stations. According to other aspects, the information can include wireless channel resources designated for a particular type of base station, or blanked by the transmitting base station, to facilitate interference reduction on such resources. By employing aspects of wireless communication management disclosed herein, efficient and reliable communication can be affected in large heterogeneous AP networks.

Abstract: Systems and methodologies are described that facilitate transmitting beac on symbols of a beacon message such that a sequence of symbols can satisfy a linear constraint over a field where the field elements can be identified w ith carriers. In this regard, a coding scheme can be applied to a beacon mes sage; the coding scheme can produce a plurality of beacon symbols to transmi t on given subcarriers. A receiving device of the beacon symbols can decode a beacon message by receiving less than the total number of symbols in a bea con message and determining the remaining symbol subcarriers based on the li near constraint. Thus, more efficient decoding of beacons is facilitated as well as resolving beacon ambiguity by figuring out which symbols satisfy lin ear constraints for the symbols, and resolving time and frequency shift by d etecting an offset that would result in satisfaction of the linear constrain t.

Abstract: Embodiments describe efficient tradeoff of latencies with processing times. A single control field can be placed within a frame to tradeoff encoding time with decoding time. Alternatively, a control field can be split into two portions to achieve good latency performance while maintaining sufficient processing time for scheduling, encoding and decoding. In accordance with some embodiments, a ACK/NACK field on one hop can serve the dual purpose of being a request for resources on the next hop in a multi-hop system. Also described is implicit acknowledgment monitoring that can improve latency performance.
