    摘要: In release 8 of the LTE standard (“Rel-8”), downlink data transmissions of one or more user equipments (UEs) in one subframe may be scheduled by control channels of different subframes. The resources for use in acknowledging whether or not a downlink data transmission was successfully received by a UE may be based on a starting control channel element (CCE) of a corresponding control channel. Two or more control channels of different subframes may have the same starting CCE, which may lead to acknowledgment resource collisions between the one or more UEs. Therefore, certain aspects of the present disclosure provide techniques to avoid acknowledgment resource collisions between the one or more UEs.

    摘要: Aspects disclosed herein relate to channel and interference estimations in a multiple transmission point environment including an eNB and RRHs. In the disclosed aspects, one or more transmission points can signal to a UE to measure channel state conditions based on a first and a second resource pattern. The UE may receive the signaling and perform interference estimation based at least in part on the first resource pattern, and channel estimation based at least in part on the second resource pattern. The UE may generate a channel state report based on the interference and channel estimations, and transmit the channel state report to a transmission point. The eNB may employ the received channel state report in scheduling one or more resources for use by the UE, and may select or adjust network traffic on the first and the second resource pattern, to affect the resulting channel and interference estimation.

    摘要: Methods, apparatuses, and articles of manufacture are disclosed for adjusting a power level in connection with transmitting parallel uplink channels. In one aspect, a user equipment determines a power-limited condition in which a total transmit power of a group of power-controlled channels exceeds a maximum level in a transmission subframe. The user equipment may determine, in an iterative fashion, power backoff values by which to establish a configured maximum power level. The parallel uplink channels in the group may be prioritized and different backoff values may be used with channels having different priorities. The user equipment may thereafter adjust a transmit power of the power-controlled channels based on the configured maximum power level.

    摘要: Methods, systems, apparatus and computer program products are provided to facilitate the transmission of channel status information in wireless systems, such as advanced long-term evolution (LTE-A) systems. Requests for aperiodic channel status reports are generated in systems that use multiple carriers and operate in multiple-in-multiple-out (MIMO) configurations. The request enables a user equipment to configure two transport blocks for the transmission of channel status information only. In some instances, data, in addition to channel status information, is transmitted by the user equipment.
