    摘要: Embodiments disclosed herein address the need in the art for reduced overhead control with the ability to adjust transmission rates as necessary. In one aspect, a first signal indicates an acknowledgement of a decoded subpacket and whether or not a rate control command is generated, and a second signal conditionally indicates the rate control command when one is generated. In another aspect, a grant may be generated concurrently with the acknowledgement. In yet another aspect, a mobile station monitors the first signal, conditionally monitors the second signal as indicated by the first signal, and may monitor a third signal comprising a grant. In yet another aspect, one or more base stations transmit one or more of the various signals. Various other aspects are also presented. These aspects have the benefit of providing the flexibility of grant-based control while utilizing lower overhead when rate control commands are used, thus increasing system utilization, increasing capacity and throughput.

    摘要: Downlink power control commands are mapped to resources used for uplink communications within a wireless communication system. An eNode B receives communications from UEs and determines the resources used by the UEs for those transmissions on the uplink which are transmitted at non-optimum power levels. Power control messages are formulated wherein the location of the power control commands is mapped to particular resources used by the UEs for their uplink transmissions. This facilitates the eNode B to dynamically assign resources for the power control commands while permitting the UEs to decode the power control messages to adjust their power accordingly.

    摘要: Techniques for accessing a wireless communication system are described. A user equipment (UE) sends a random access preamble for system access. The random access preamble may include a random identifier (ID), a channel quality indicator (CQI), etc. The UE may randomly select the random ID or may be assigned this random ID. The UE receives a random access response from a base station. The random access response may include control channel resources (e.g., CQI and PC resources), uplink resources, and/or control information (e.g., timing advance and PC correction) for the UE. The random access response may be sent in two parts using two messages. A first message may be sent on a control channel and may include identification information and possibly other information. A second message may be sent on a shared data channel and may include remaining information for the random access response.

    摘要: Channel dependent credit accumulation for determining a mobile handover is provided herein. In some aspects, a characteristic(s) of a source channel(s) serving a mobile device and of one or more target channels can be evaluated. Magnitudes of the evaluated characteristics can be utilized to generate handover credits associated with the target channel(s) (e.g., based on some function of a difference in the magnitudes). If a concurrent number of credits associated with a target channel equals or rises above one or more threshold levels, a mobile device can initiate a handover. As described, disparity in source and target channel quality, signal strength, etc., can be determined to increase probability of a handover based on channel degradation over one or more time intervals.

    摘要: Systems and methods are provided for a learning-based determination of semi-persistent scheduling of data-packet flow wireless communication. A packetized data flow served to a wireless terminal is fully scheduled for an initial period of time in order to collect statistics associated with scheduled packet sizes (Ss) and inter-packet times (Ts). Analysis of a cumulative distribution of {S, T} pairs indicate whether a characteristic packet size (S0) and size dispersion (D0) are associated with the cumulative distribution. Inter-time intervals associated with the characteristic size and dispersion complete a transport format. Semi-persistent scheduling is utilized for a packetized flow when a characteristic transport format can be extracted, or learned, from the accumulated statistics. Extracted transport formats can be employed to optimize scheduling efficiency upon handover.

    摘要: Techniques for acknowledging data transmissions in a multi-carrier wireless communication network are disclosed. In some aspects, a user equipment (UE) receives a data transmission on at least one component carrier (CC) in a plurality of configured CCs. The UE determines acknowledgement/negative acknowledgement (ACK/NACK) information for the data transmission and determines an uplink channel for sending the ACK/NACK information. When the ACK/NACK information is sent on a PUCCH, the UE may perform power control based on which CCs in the plurality of configured CCs data is received. When the ACK/NACK information is sent on a PUSCH, the UE may determine a number of resource elements based on its CC configuration.

A UE may receive load indicator signals from a plurality of base stations in adjacent cells and determine, based at least in part on the load indicator signals, a transmit power metric. The transmit power metric may be provided to a serving base station, which may allocate uplink resources based on the transmit power metric. Additional information related to receiver sensitivity and/or path loss may be used to determine the transmit power metric.
