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： Certain aspects of the present disclosure propose techniques for bundling and ciphering service data units (SDU) in the packet data convergence protocol (PDCP) layer. The proposed techniques increase the data rate of the communication system. At the transmitter side, the PDCP layer may bundle SDUs and cipher each SDU individually before submitting them to a lower layer. At the receiver-side, the PDCP layer may unbundle and decipher the SDUs before submitting them to higher layers.

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： Techniques for bundling and ciphering data prior to transmission are described. In an exemplary design, a transmitting entity receives a plurality of service data units (SDUs) from an upper layer, assigns sequential sequence numbers to the SDUs, and bundles the SDUs into a single protocol data unit (PDU). In one design, the transmitting entity generates a single count value based on a sequence number of a designated SDU (e.g., the first SDU) in the PDU and ciphers all SDUs based on the single count value. In another design, the transmitting entity ciphers each segment of at least two SDUs in the PDU based on a count value for that segment. The transmitting entity generates a header with at least one sequence number and possibly length and/or other information for the SDUs. The transmitting entity forms the PDU with the header and the SDUs and passes the PDU to a lower layer.
