摘要： Systems and methodologies are described that facilitate transmitting beacon symbols comprising static and dynamic information about the beacon and/or a transmitter thereof (or substantially any information a beacon transmitter desires to send). In this regard, the beacon symbol transmitter can select a subcarrier of bandwidth for transmitting the beacon symbol where the subcarrier is indicative of data and is in one of a plurality of subcarrier groups related to the total available subcarriers. Thus, the groups can have common virtual subcarriers such that a subcarrier index can be found in each group. In this way, the selected group can indicate additional information that can change based on what group is selected for transmitting a given beacon symbol.

摘要： Communication techniques enable efficient communication to an UE (User Equipment) that is subject to a dominant interference signal that is transmitted by a different base station. Disclosed interference cancellation techniques, both UE-centric and network-centric, are suitable to this situation. These techniques are particularly advantageous when undesirable or difficult to introduce changes in the physical (PHY) and medium access control (MAC) layers at the existing base stations. UE-centric framework refers to an approach largely implemented by UEs to include pico or femto cells. Network-centric framework closed-loop coordination between base stations and UEs mitigate interference thereby improving network performance. In particular, an interfering base-station can help a "victim" UE by adjusting downlink pilot and control power and to adjust traffic data rates responsive to information that the "victim" UEs provide, including information about the interfering link and performance of the cancellation itself sent over the air or using the backhaul.

摘要： Techniques for sending signaling messages with beacon signals in a wireless communication network are described. In one design, a transmitter station may map a signaling message (e.g., a reduce interference request) to multiple code symbols. The transmitter station may select multiple resource elements from among a plurality of resource elements based on the multiple code symbols. In one design, each code symbol may be sent across frequency by selecting one of multiple subcarriers in one symbol period (500). In another design, each code symbol may be sent across time by selecting one of multiple symbol periods on one subcarrier (700). The transmitter station may generate a beacon signal having transmit power on the selected resource elements and no transmit power on remaining resource elements. The transmitter station may send the beacon signal to at least one receiver station.
