    摘要: Providing for improved error control signaling in wireless communications is disclosed herein. By way of example, multiple transmissions can be conducted for a HARQ process prior to a scheduled feedback signal on the HARQ process, causing a receiving device to combine the multiple transmissions, rather than treat them as separate transmissions. In this manner, multiple transmissions can be employed to increase overall receive energy, without violating maximum transmit power constraints in a wireless communication. Further, these multiple transmissions can be configured based on prevailing signal strength at the receiving device, or based on processing capabilities of the receiving device, providing flexible protocols that can accommodate advanced as well as legacy UEs in wide range of wireless conditions.

    摘要: Systems and methodologies are described that facilitate selecting frequency for transmitting control channel format indicator (CCFI) data such to identify a related cell. In one example, the CCFI data can be transmitted in an initial portion of frequency (such as an orthogonal frequency division multiplexing (OFDM) symbol) in a time transmit interval (TTI). The CCFI data can be spread across the initial portion of frequency and be shifted to identify the transmitting cell. Additionally, the CCFI data can be scrambled to further identify the cell. The CCFI data can also be utilized to determine structure of subsequent control and/or data channels.

    摘要: Systems and methodologies are described that facilitate evaluating and utilizing timing updates in a wireless communications network. A base station can transmit timing adjustment commands to mobile devices as needed as opposed to a periodic timing update where timing adjustment commands are always sent within a certain period. However, the mobile devices need to stay awake to monitor the timing adjustment message resulting in high power consumption. On the other hand with periodic update, the mobile devices can wake up to check whether there is a timing adjustment for itself and, if not, return to a sleep mode. With the proposed method, a mobile device can sleep for a period of time to check for timing adjustment commands upon waking. Thus, both the mobile power consumption and downlink signaling overhead are reduced.

    摘要: Techniques for sending a MIMO transmission using a combination of cyclic delay diversity and precoding are described. A set of delays (e.g., zero delay, small delay, and large delay) for cyclic delay diversity and a set of precoding matrices may be supported. In one design, a Node B may select a delay specifically for a UE or for a set of UEs served by the Node B. In another design, a UE may evaluate different combinations of precoding matrix and delay, determine the combination with the best performance, and send this combination of precoding matrix and delay to the Node B. The Node B may perform precoding with the precoding matrix and then processing for cyclic delay diversity based on the selected delay. Alternatively, the Node B may perform processing for cyclic delay diversity based on the selected delay and then precoding with the precoding matrix.

    摘要: Transmission of eMBMS signals by at least one network entity of a wireless communications system may include coordinating transmission of eMBMS signaling with a remote access point of a wireless communications system to broadcast the eMBMS signaling from a multiple antenna matrix comprising at least one antenna of the network entity and at least one antenna of the access node. The network entity may be an access point. The access point may vary a precoding matrix applied to the eMBMS signaling to transmit from the network entity, or use alternative techniques for providing transmit diversity. Accordingly, the access point may provide transmit diversity for the eMBMS signaling transmitted from the multiple antenna matrix implemented between different cells on the wireless communication network. The access point may vary the precoding matrix to cause cyclical rotation of beam direction for the eMBMS transmissions from different cells of the network.
