    摘要: Techniques for handling inconsistent control information in a wireless communication system are described. In an aspect, inconsistent control information is handled in different manners for the downlink and uplink. In one design, a user equipment (UE) receives a first grant with first control information for a first data transmission and also receives a second grant with second control information for a second data transmission. The UE determines that the second control information is inconsistent with the first control information, e.g., due to the two grants conveying different transport block sizes. The UE determines whether to retain or discard the second grant based on whether the two grants are for data transmissions on the downlink or uplink. In one design, the UE retains the second grant if the two grants are for data transmissions on the downlink and discards the second grant if the two grants are for data transmissions on the uplink.

    摘要: Certain aspects of the present disclosure relate to a method for sending control information to multiple user terminals that share the same resources in a Spatial Division Multiple Access (SDMA) wireless system. The control information can be transmitted from an access point over a physical downlink control channel (PDCCH) that is common for a plurality of user terminals. The overall PDCCH overhead can thus be reduced due to a smaller number of required PDCCH in the SDMA wireless system.

    摘要: Systems and methodologies are described that facilitate allocating uplink resources to mobile devices to employ to signal acknowledgment indicators. Persistently scheduled mobile devices can be explicitly assigned uplink resources. Dynamically scheduled mobile device can utilize a one-to-one mapping to identify uplink resources based upon a downlink control channel index. The one-to-one mapping can be revised to remove associations between downlink control channel indices and resources allocated to persistently scheduled users and/or reserved for other control signaling in a mixed resource block. In addition, downlink control channel indices can be selected to avoid collisions between dynamic and persistent users.

    摘要: Certain aspects of the present disclosure relate to techniques for determining resource elements REs used for Coordinated Multipoint (CoMP) transmission schemes. The techniques generally include determining, by a User Equipment (UE), a set of data REs used for Coordinated Multipoint (CoMP) operation. The determination is based on a CoMP scheme and data REs available to particular base stations involved in the CoMP operation. The technique further includes processing data received via the CoMP operation on the determined set of data REs.
