摘要： A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus generates a codeword, determines at least one puncture to the codeword based on allowing a legacy receiver to decode the codeword without knowledge of the at least one puncture, replaces each of the at least one puncture with a pilot, and transmits the codeword. The apparatus may also generate an IEEE 802.11 codeword having pilots in a first set of subcarriers, and puncture the codeword with additional pilots unknown to a legacy receiver in a second set of subcarriers. Accordingly, when an original set of pilot symbols is insufficient or inappropriately placed in a resource structure, a codeword may be transmitted with a new pilot structure capable of being decoded by legacy receivers not aware of the new pilot structure.

摘要： Sets of communications resources, e.g., sets of peer discovery resources, in a peer to peer communications system are used concurrently by multiple transmitting devices. The communications system supports a plurality of different pilot sequences. Multiple transmitting devices may transmit their signals on the same set of communications resources, but with different pilot sequences. This approach allows receiving devices to distinguish between multiple signal sources, e.g., wireless terminals, using a shared communications resource. A wireless communications device monitors a plurality of different sets of communications resources and selects, e.g., based on received energy levels, a set of communications resources from said plurality of different sets of communications resources to use for communication. The communications device further selects one of a plurality of different pilot sequences to use for said communication and transmits pilot signals using the selected pilot sequence and at least a portion of the selected set of communications resources.

摘要： A method, an apparatus, and a computer program product for wireless communication are provided in which a first eNB may be operable to determine a set of resources to allocate for D2D communications based on one or more network factors and transmit the set of resources allocated for D2D communications. A first UE may receive the set of resources allocated for D2D communications. A second UE may inform the first UE of a set of resources allocated for D2D communications by a second eNB. The first UE may determine a subset of resources to use for D2D communications with a second UE based on one or more D2D resource determination schemes, and may signal the determined subset to the first eNB. The first eNB may receive the subset of resources and transmit a control signal indicating that the subset of resources has been allocated for D2D communications.
