    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: A method, apparatus, and computer program product for wireless communication are provided in which a transmission power is prioritized between an access channel and a second channel. Additionally, the access channel and the second channel are transmitted simultaneously. Each of the access channel and the second channel are transmitted at a transmission power determined based on the priority. Further, a method, apparatus, and computer program product for wireless communication are provided in which information is received regarding first resources to use for transmitting an access channel with an acknowledgment and second resources for transmitting the access channel with a negative acknowledgment. Further, the access channel is transmitted on the first or second resources.

    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: Certain aspects of the present disclosure provide techniques for determining resources for transmission of acknowledgement messages to a user equipment (UE). The techniques involve receiving a plurality of codewords from the UE via an uplink component carrier, and determining at least first and second index pairs identifying resources of a downlink channel to be used for transmitting acknowledgement messages for the received codewords. The first index pair is determined based on a first set of parameters, and the second index pair is determined based on the first set of parameters and a second set of one or more parameters. At least one of the parameters in the second set is a fixed value.
