    摘要: Techniques for transmitting control information to support communication on multiple component carriers (CCs) are disclosed. A user equipment (UE) may be configured for operation on multiple CCs. These CCs may be associated with control messages having different definitions. For example, a control message for a CC configured for frequency division duplex (FDD) may have a different definition than a control message for a CC configured for time division duplex (TDD). A base station may send first control information for a first CC based on a definition of a control message for a second CC, instead of a definition of a control message for the first CC. The control message for the second CC may be selected for use to send the first control information based on various designs.

    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: A method for wireless communications is disclosed that includes determining a power operation control feature of a first mode of operation of a user equipment (UE). A channel prioritization is triggered based at least in part on the power operation control feature. A second configuration indicating UE operation in a second mode is received and is based on a UE generated report of a state resulting from the first mode of operation. The second mode of operation is then implemented.

    摘要: Techniques for supporting operation on multiple carriers are described. In an aspect, a carrier indicator (CI) field may be used to support cross-carrier assignment. The CI field may be included in a grant sent on one carrier and may be used to indicate another carrier on which resources are assigned. In one design, a cell may determine a first carrier on which to send a grant to a UE, determine a second carrier on which resources are assigned to the UE, set a CI field of the grant based on the second carrier and a CI mapping for the first carrier, and send the grant to the UE on the first carrier. The UE may receive the grant on the first carrier from the cell and may determine the second carrier on which resources are assigned to the UE based on the CI field of the grant and the CI mapping for the first carrier.

    摘要: Techniques for supporting multimedia broadcast/multicast services (MBMS) are described. In an aspect, resources used for MBMS services may be provided with a multi-tier structure. In the first tier, resources (e.g., subframes) used for a multicast control channel (MCCH) for MBMS services may be signaled in a system information block (SIB). In the second tier, resources (e.g., subframes) for channels carrying data for MBMS services may be signaled via the MCCH. In one design, a base station/cell may determine resources used to send a MCCH. The cell may generate a SIB comprising information indicative of the resources used to send the MCCH. The cell may send the SIB in a broadcast control channel (BCCH). The cell may send the MCCH on the resources indicated by the information sent in the SIB. The cell may send other channels carrying data for MBMS services based on information sent in the MCCH.

An example of a first method can include providing one or more discontinuous reception cycles respectively corresponding to one or more inactivity periods. During respective awake periods of the one or more discontinuous reception cycles, data can be received on respective ones of one or more frequency carriers. The number and type of the one or more frequency carriers on which data is received can be determined based on the one or more inactivity periods. Further, in some embodiments, in addition to providing discontinuous reception on selected frequency carriers, data can be received according to continuous reception on other frequency carriers, such as the anchor carrier.

    摘要: Techniques for sending control information to support operation on multiple component carriers (CCs) are disclosed. A user equipment (UE) may be configured with multiple CCs for carrier aggregation. The multiple CCs may be associated with different uplink-downlink configurations and may have different downlink subframes and uplink subframes. In one aspect, uplink control information (UCI) for a secondary CC (SCC) may be sent on a primary CC (PCC) based on a UCI transmission timeline for the PCC (and not based on a UCI transmission timeline for the SCC). For example, a downlink grant for the SCC may be sent based on a downlink grant transmission timeline for the PCC. In another aspect, uplink grants for an SCC may be sent on the PCC based on an uplink grant transmission timeline for the PCC (and not based on an uplink grant transmission timeline for the SCC).

    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: Bandwidth segmentation according to a one carrier approach conveyed in a main information block (MIB) supports a plurality of contiguous frequency segments with one frequency segment seen by legacy terminals and the whole bandwidth seen by advanced terminals. Control regions either within data regions of a legacy frequency band segment or with one or two contiguous advanced frequency band segments separated by the legacy frequency band segment are communicated to advanced terminals in system information blocks (SIBs) or conveyed to an advanced UE by dedicated signaling.
