    摘要: Systems and methodologies are described that facilitates communicating Physical Control Format Indicator Channel (PCFICH) information to a user equipment (UE) in which the PCFICH information is specific to a particular component carrier. The PCFICH information for each component carrier can be communicated via an anchor component carrier in order to reduce decoding each PCFICH information for each component carrier. In particular, the PCFICH information can be decoded for an anchor component carrier and PCFICH information for additional carriers can be included in a Multi-Carrier (MC) grant of the Physical Downlink Control Channel (PDCCH).

    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 reporting channel quality information (CQI) in a multi-carrier wireless communication system are disclosed. In one aspect, a user equipment determines one or more reporting groups, each comprising a plurality of component carriers which are configured for the user equipment. The user equipment may detect a trigger from a base station that selects a reporting group and may respond to the trigger by sending CQI for at least the activated component carriers in the selected reporting group.

    摘要: Techniques for supporting communication with carrier extension are described. In one design, a base carrier and at least one segment available to a user equipment (UE) for communication may be determined. At least one operating parameter for the UE may be determined based on a composite bandwidth of the base carrier and the at least one segment. The UE may communicate based on the at least one operating parameter, which may include a resource block group (RBG) size and/or a bitmap used for resource allocation on the downlink, a gap used for resource allocation with frequency hopping on the downlink, a number of hopping bits used for resource allocation with frequency hopping on the uplink, a subband size and/or a number of bandwidth parts used for channel quality indicator (CQI) reporting, a sounding reference signal (SRS) bandwidth and/or a SRS configuration for SRS transmission on the uplink, and/or other operating parameters.

    摘要: Techniques for supporting fallback operation in a multi-carrier communication system are described. In one aspect, a UE may determine at least one first downlink control information (DCI) format to monitor on a first carrier. The UE may monitor for the first DCI format(s) on the first carrier to detect DCI sent to the UE. The UE may receive a reconfiguration message related to communication on a plurality of carriers by the UE with cross-carrier signaling, and may determine at least one second DCI format to monitor on the first carrier based on the reconfiguration message. The UE may monitor for the first DCI format(s) and the second DCI format(s) on the first carrier after receiving the reconfiguration message.

    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.
