摘要： A method, an apparatus, and a computer program product for wireless communication are provided in which a network entity may be operable to communicate D2D resource allocations to a UE supported by a HeNB. In one example, the network entity may be operable to determine whether a HeNB is operable to communicate system information to a UE. As used herein, system information may include, but is not limited to, D2D resource allocations, paging information, etc. When the network entity determines that a HeNB is operable to communicate system information to a UE, then it may transmit the system information to the HeNB to allow the HeNB to convey the system information to the UE. When the network entity determines that a HeNB is not operable to communicate system information to a UE, then it may transmit the system information to the UE via one or more other network entities.

摘要： A method, an apparatus, and a computer program product for wireless communication are provided in connection with minimizing device-to-device D2D ready-to-send/clear-to-send RTS/CTS signaling overhead resource usage. In one example, a WAN entity, e.g. eNB, is equipped to receive one or more channel gain values from a plurality of UEs, determine that a connection identification CID can be reused by multiple D2D links based on the received one or more channel gain values, and transmit information indicating that the CID may be reused. In another example, a UE is equipped to measure a direct power signals and an inverse power echoes on a CID used for a link formed between a third and fourth UE, and determine that the CID may potentially be reused by a link formed with a second UE for D2D RTS/CTS signaling, based at least in part on the measured direct power signals, measured the inverse power echoes, and a signal-to-interference ratio SIR threshold.

摘要： In a first method, a first apparatus determines a channel gain to a second apparatus with which the first apparatus is communicating. The first apparatus determines interferer backoff information that ensures an interference level at the first apparatus such that a signal received from the second apparatus can be decoded reliably. The interferer backoff information is determined based on the channel gain. The first apparatus transmits information based on the interferer backoff information in a message to the second apparatus. In a second method, a first apparatus in communication with a second apparatus determines a channel gain to a third apparatus with which the first apparatus can potentially interfere. The first apparatus receives a message from the third apparatus. The message includes interferer backoff information. The first apparatus determines a power for transmitting a signal to the second apparatus based on the interferer backoff information and the channel gain.

摘要： Systems and methodologies are described herein that facilitate interference control and resource management in a wireless communication system. As described herein, a base station, terminal, and/or other entity in a wireless communication system that observes interference from one or more other network entities can construct and communicate resource utilization messages (RUMs) in order to request the interfering network entities to conduct power backoff on designated resources. Parameters constructed as a function of quality of service (QoS) and/or priority metrics (such as head-of-line delays, queue lengths, burst sizes, delay targets, average rates, or the like) can be included within the RUM, such that an entity receiving the RUM can compute QoS changes associated with various power backoff levels in order to select a power backoff level that maximizes overall system QoS performance.
