    摘要: Systems and methodologies are described that facilitate cycling through precoders for transmitting wireless network communications in a time domain. The precoders can be cycled according to a precoder sequence for each data symbol transmission. When the last precoder is selected the cycle can begin again, a new precoder sequence can be received or defined, and/or the like. A precoder sequence related to a subset of precoders present in a wireless device can be defined sequentially, cyclically shifted according to an identifier or one or more communications parameters, randomly, pseudo-randomly according to an identifier or one or more communications parameters, and/or the like. In addition, the precoder sequence can be utilized to select a precoder for one or more retransmissions. Such cycling of precoders can increase transmit diversity.

    摘要: A system and method for facilitating resource management in OFDM systems is provided. The system permits different and flexible resource cell metric operations levels (e.g. uplink load management, admission control, congestion control, signal handoff control) for different sub-bands. For the uplink load management, there are multiple distinct load operation points (e.g. IoT, RoT) per sub-band group instead of the same operation level across the entire available band. The sub-band groups encompass the entire band. The facilitation system also comprises a variety of transmitting protocols, command increment variable stepsize methods and robust command response methods. The system thus provides more flexible reverse link resource management and more efficient utilization of the bandwidth.

    摘要: Techniques for assigning acknowledgement (ACK) resource to a user equipment (UE) in a wireless communication system are described. In one design, a first parameter indicative of radio resources (e.g., the lowest index of at least one physical resource block) allocated to the UE for data transmission may be obtained. A second parameter indicative of another resource (e.g., a cyclic shift of a reference signal sequence) assigned to the UE for data transmission may also be obtained. The first and/or second parameter may be restricted, and each restricted parameter may be limited to a set of allowed values among all available values for the parameter. ACK resource assigned to the UE for data transmission may be determined based on the first and second parameters. In one design, sequential first parameter values may be mapped to sequential ACK resources indices. In another design, mirror mapping with different mapping directions may be used for different allowed values of the second parameter.

    摘要: A method for enhancing a sounding reference signal (SRS) in a non-root wireless communication device is disclosed. The method determines that all SRS transmissions for the wireless communication device are to occur in an uplink pilot time slot (UpPTS) portion of a transition subframe. The method also determines whether available uplink bandwidth for the UpPTS portion is greater than available uplink bandwidth for a normal uplink subframe. A current SRS is transmitted using the available uplink bandwidth for UpPTS portion when the available uplink bandwidth for the UpPTS portion is greater than available uplink bandwidth for the normal uplink subframe.

    摘要: Methods and apparatuses are provided for bundling resource blocks (RB) for varying bandwidth scenarios in wireless communication. Where multiple access points form a coordinated multiple point (COMP) set for a device. the access points may be configured to use a common RB bundling size for precoding transmissions to the device. In another aspect, where a device is allocated a bandwidth and a bandwidth extension, a RB bundling size may be determined for the bandwidth and bandwidth extension, jointly or individually. The RB bundling size may be determined based on the bandwidth or on the bandwidth and the bandwidth extension.
