    摘要: A method includes receiving a cross-subframe assignment in a first subframe, targeting a second subframe in which a transmission power control (TPC) command is to be applied. The method may also include adjusting transmit power in accordance with the TPC command during a third subframe, a predefined number of subframes after the first subframe. Another method includes receiving a cross-subframe assignment in a first subframe. The cross-subframe assignment targets a second subframe in which a first TPC command is to be applied. The method may also include receiving a nominal grant in the first subframe that targets an identified subframe to which a second TPC command is to be applied. The method may also include adjusting the transmit power according to the first TPC command, the second TPC command or a function of the first TPC command and the second TPC command during the second subframe or the identified subframe.

    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: A wireless communication device for determining a reference subframe is described. The wireless communication device includes a processor and instructions stored in memory that is in electronic communication with the processor. The wireless communication device determines a reporting subframe n. The wireless communication device also determines a reference subframe n−nreference based on a limit and at least one limiting criterion. The wireless communication device further generates a report based on the reference subframe if the reference subframe is determined. The wireless communication device additionally sends the report during the reporting subframe if the reference subframe is determined.

    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.

    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.
