    摘要: Systems and methodologies are described that facilitate selecting an uplink carrier for random access within a wireless environment having multiple carriers. Selection of an uplink carrier for random access can be randomly selected from a set of available uplink carriers. Additionally, the uplink carrier for random access can be selected based upon which uplink carrier is paired with an anchor carrier. Further, the uplink carrier for random access can be identified based upon a bandwidth related to the user equipment (UE). Reference signals can also be employed in order to identify an uplink carrier to perform random access.

    摘要: The described aspects include methods and apparatus for communicating control information in a carrier aggregation configuration that uses multiple radio access technologies (RAT). A first resource assignment related to a first carrier corresponding to a first RAT can be received, as well as, a second resource assignment related to a second carrier corresponding to a second RAT. The first carrier and the second carrier are aggregated for communicating data in a wireless network. In addition, resources can be determined for communicating first RAT control data for the first RAT over an uplink carrier based at least in part on the first resource assignment. Second RAT control data can then also be communicated in containers and/or using timing for control data of the first RAT over at least a portion of the resources.

    摘要: Techniques for reporting channel state information (CSI) in a multi-carrier wireless communication system are disclosed. In some examples, a user equipment determines a configuration for reporting CSI for each component carrier (CC) in a plurality of component carriers. For a first subframe, the user equipment determines a priority for transmitting CSI associated with the plurality of CCs based at least in part on the configuration. The user equipment sends, in the first subframe, a CSI report including the prioritized CSI. The CSI report can include CSI for a single CC, or CSI for multiple CCs. For multi-CC reporting of CSI, the user equipment can multiplex CSI reports or CSI elements for the plurality of CCs up to an available payload size.

    摘要: A method of wireless communication includes receiving overlapping information triggering aperiodic sounding reference signal (SRS) transmission. The method also includes processing the overlapping information in accordance with the received triggering information. The overlapping information can be consistent configuration information for the aperiodic SRS transmission, in which case the processing includes transmitting an aperiodic SRS in accordance with the configuration information. When the overlapping information has dissimilar configurations for the aperiodic SRS transmission, the processing includes treating the overlapping information as an error event. The overlapping information can be a trigger received in an uplink grant and a trigger received in a downlink grant. The wireless system can be a multicarrier system including multiple component carriers.

    摘要: Techniques for reporting channel state information (CSI) are disclosed. A user equipment (UE) may be configured for operation on multiple carriers with different configurations, e.g., FDD and TDD carriers and/or carriers with different uplink-downlink configurations. The multiple carriers may have different subframes for making measurements for CSI and/or different subframes for sending CSI. In response to a CSI request, the UE may determine at least one reference subframe to use for determining CSI for the multiple carriers. The reference subframe may be common to the plurality of carriers and may, for example, be based the subframe in which the CSI request in sent. Alternatively, the reference subframe may be different for different carriers such as when it is based on different HARQ timelines applicable for the different carriers. The UE may determine the CSI for the multiple carriers based on the reference subframe(s) and may report the CSI.

    摘要: In accordance with one or more aspects and corresponding disclosure thereof, various aspects are described in connection with channel quality indicator (CQI) feedback in connection with one or more downlink carriers. An anchor carrier scheme is employed to provide channel quality indicator (CQI) feedback of one or more downlink carriers. An indication is set to identify that a designated uplink carrier is used to convey the CQI feedback. An uplink carrier is selected from a set of uplink carriers as an anchor carrier to convey the CQI feedback. CQI feedback is transmitted for one or more downlink carriers using the designated carrier.
