    摘要: In a wireless communication system unused resource elements are utilized to transmit additional pilot and control signals. The additional pilot and control signals may mitigate the impact of interference. The unused resource elements may be in a downlink pilot timeslot (DwPTS) in a time division duplex system.

    摘要: A method for improving channel estimation in a wireless communication system is disclosed. A wireless signal that includes a plurality of multipath components is received. N channel estimates are then obtained, where N is any positive integer greater than one. Each channel estimate of the N channel estimates corresponds to a different multipath component of the plurality of multipath components. The effects of interference between the plurality of multipath components on the N channel estimates is then reduced.

    摘要: Certain aspects of the disclosure relate to performing cross-subframe control channel signaling for wireless communications. A method may be provided for signaling downlink control channel resource allocations and/or physical control format indications in a subframe different from the subframe in which a downlink data transmission may be performed. In one aspect, the method may include transmitting PDCCH and/or PCFICH during a first subframe to allocate resources for a PDSCH during a second subframe and transmitting the PDSCH during the second subframe.

    摘要: Systems and methodologies are described that facilitate adaptively communicating data to wireless devices. An access point can precode a dedicated reference signal (DRS) for transmitting to a wireless device, and the wireless device can receive the precoded DRS. The wireless device can determine the precoder by estimating a channel of the DRS and can provide channel condition feedback to the access point. The access point can create data signals including a single or a burst of data transmissions according to the feedback and can precode the data signals using the same precoder. The wireless device can additionally decode the data signals using the precoder. Moreover, the access point can cycle through precoders according to a patterned, random, pseudo-random, and/or similar sequence.

    摘要: Carrier aggregation to enhance Evolved Multimedia Broadcast Multicast Service (eMBMS) includes transmitting unicast signaling for a unicast service on an anchor carrier to mobile entities, transmitting eMBMS signaling on a second carrier different from the anchor carrier to the mobile entities for use with the unicast signaling, and various techniques for practical application of carrier aggregation for eMBMS enhancement. In addition, allocating subframes used for MBMS on a Single Frequency Network (MBSFN) includes allocating at least a portion of one or more subframes otherwise reserved for unicast subframes on a mixed carrier to provide an increased allocation of subframes carrying MBSFN information, transmitting MBSFN signals on the increased allocation of subframes, and more detailed aspects.
