摘要： A method transmits long term evolution (LTE) measurement reports on an uplink. The method manages invalid reference subframes in a multicarrier configuration. The managing can be implemented by transmitting measurement reports for component carriers with valid reference subframes; and omitting measurement reports for at least one component carrier with an invalid reference subframe.

摘要： Techniques for transmitting data by a power-limited user equipment (UE) in a wireless communication system are described. The UE may transmit data of different types on one or more carriers and may be power limited. In some aspects, the UE may prioritize the data to transmit based on the priorities of the different data types, the priorities of carriers on which the data is transmitted, and/or other criteria. In one design, the UE may obtain data to transmit on at least one carrier for the uplink. The UE may determine that it is power limited for transmission on the at least one carrier. The UE may prioritize the data to transmit based on at least one criterion. The UE may allocate its available transmit power to the prioritized data and may transmit the prioritized data at the allocated transmit power.

摘要： Certain aspects of the present disclosure relate to techniques for user-specific search space design for multi-carrier operation in Long Term Evolution Advanced (LTE-A) systems. The user-specific search space can be designed for searching Physical Downlink Control Channels (PDCCHs) transmitted on one component carrier (CC) that schedules Physical Downlink Shared Channel/Physical Uplink Shared Channel (PDSCH/PUSCH) transmissions on two or more different CCs. In one aspect, multiple independent user-specific search spaces can be designed. In another aspect, one user-specific search space can be randomly derived and then expanded to accommodate search for multiple CCs. In yet another aspect, the search space design can retain randomness in starting search element indices of multiple PDSCH/PUSCH CCs, while overlapping of search spaces for multiple PDSCH/PUSCH CCs can be avoided.

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： 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.
