    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: Methods and apparatus for processing channel quality information (CQI) and scheduling resources subject to cooperative resource allocation based on the CQI are provided. To convey the CQI for protected/unprotected subframes in a single report, a new vector CQI format may be utilized. Two alternatives for CQI processing this vector format and the advantages of each are described. In the first alternative, a single entry from the CQI vector is selected for processing by a downlink scheduler and/or other media access control (MAC) blocks (e.g., a PHICH, DCI power control, and/or PDCCH scheduler). In the second alternative, the selection from the CQI vector is made on a per-subframe basis, and both the subframe and the selected CQI element are processed by the downlink scheduler and/or the other MAC blocks. In this manner, better scheduling decisions may be made using the CQI vector.

    摘要: Existing criteria for analyzing radio link failure conditions may not satisfactorily address the conditions between cells that support cooperative resource coordination. Generally, when the UE declares radio link failure, the UE discontinues communication with a serving base station and searches for a new base station. When the UE lies in a region with severe interference, where the interference is coordinated between base stations by the interfering cell yielding part of its resources, the UE measurements for determining radio link failure (RLF) may vary considerably, depending on whether the measured resources were yielded by the interfering cell. When the UE measures resources which were not yielded by the interfering cell, the UE can erroneously declare RLF (e.g., due to high interference), although the UE can still access the serving cell using resources yielded by the interfering cell. Accordingly, disclosed are aspects for determining RLF based by accounting for cooperative resource coordination employing yielded resources.

    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.
