摘要： Techniques for transmitting and receiving a reference signal in a wireless network are described. In one design, a UE may generate multiple transmissions of a reference signal at multiple frequency locations. The UE may send the transmissions of the reference signal in multiple symbol periods of at least one subframe. The UE may send at least two transmissions of the reference signal in each subframe, e.g., one transmission of the reference signal in each symbol period of a subframe. Each transmission of the reference signal may cover a portion of the bandwidth of the reference signal and may be sent on a set of contiguous subcarriers at a particular frequency location. The multiple transmissions of the reference signal may cover the entire bandwidth of the reference signal. A location estimate for the UE may be determined based on time of arrivals (TOAs) of the reference signal measured by multiple receiver stations.

摘要： A method and apparatus for dynamic interference management is disclosed. A frequency channel is partitioned into a plurality of groups. Two or more groups are assigned weights reflecting degrees of disadvantage of a node. Each group is further partitioned into a plurality of tones. A node experiencing interference determines a group, selects a tone within the group, and transmits a wireless signal using the selected tone. A receiving node receives a plurality of tones including the selected tone, identifies active tones from the received tones, and determines a response based on the weights of the active tones.

摘要： All or a portion of a timeslot of a slotted communication system may be dynamically designated for transmitting or for receiving. For example, a timeslot originally designated for receiving information at a wireless node may be temporarily designated for transmitting information from the wireless node. Such a designation may be made to accommodate a temporary asymmetry in traffic flow between wireless nodes or may be made based on other criteria. In some aspects, a resource utilization messaging scheme may be employed to mitigate interference associated with the designation of timeslots for transmitting or receiving.

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.

摘要： Methods and apparatus well suited to decentralized traffic scheduling in wireless peer to peer network are described. An individual wireless terminal corresponding to a peer to peer connection makes a transmitter yielding or receiver yielding decision for a traffic slot. Quality of service information is disseminated as part of the scheduling control signaling. A scheduling control signal, e.g., a traffic transmission request signal or a traffic transmission request response signal, includes a pilot portion and a quality of service information portion. The pilot facilitates the recovery of the quality of service information by a plurality of different devices which may have different channel conditions with respect to the transmitter of the scheduling control signal. The different devices may benefit from utilizing the recovered quality of service information in making a yielding decision regarding traffic signaling in a traffic segment.

摘要： An adaptable decision parameter is used to determine whether to react to resource utilization messages. The decision parameter may comprise a decision threshold that is adapted based on received resource utilization messages. The decision parameter may comprise a probability that is used to determine whether to react to a received resource utilization message. Such a probability may be based on, for example, one or more channel conditions, the number of interferers seen by a node, the number of received resource utilization messages, or some other form of resource utilization message-related information.

摘要： Systems and methodologies are described that facilitate scheduling over multiple hops in a wireless communication network. Radio resources can be partitioned into sets of sub-frames that can be allocated statically and/or dynamically. Statically allocated radio resources can be reassigned over time based on the loading on each hop and/or throughput imbalance. In addition, dynamic assignment of sub-frames to each hop can be based on traffic or channel conditions. Moreover, the radio resources can be dynamically allocated in a distributed scheme, wherein a base station controls the scheduling of resources, or a centralized scheme, wherein a relay station controls the scheduling of resources. Furthermore the allocation of radio resources can be transparent or explicit. In the transparent case, the access terminal listens directly to the base station, and the relay station does not transmit control information, such as DL or UL assignments. Conversely, when the allocation of resources is explicit the relay station does transmit control information.
