    摘要： Techniques for supporting high decoding throughput are described. A transmitter may encode a code block of data bits with a Turbo encoder. A receiver may perform decoding for the code block with a Turbo decoder having multiple soft-input soft-output (SISO) decoders. A contention-free Turbo interleaver may be used if the code block size is larger than a threshold size. A regular Turbo interleaver may be used if the code block size is equal to or smaller than the threshold size. The contention-free Turbo interleaver reorders the data bits in the code block such that information from the multiple SISO decoders, after interleaving or deinterleaving, can be written in parallel to multiple storage units in each write cycle without encountering memory access contention. The regular Turbo interleaver can reorder the data bits in the code block in any manner without regard to contention-free memory access.

    摘要： In a wireless network (100) with HSDPA-enabled user equipment devices (130), the base transceiver station (120) transmits to each HSDPA-enabled UE information regarding allocation of HSDPA codes and associated modulation techniques for other HSDPA-enabled UEs. Using this additional control information, each UE configures decision feedback filter of its equalizer to reduce inter-user interference. The additional control information may be transmitted in a packet (300) that includes a CRC portion (310) with the packet's CRC masked by a common ID, which is known to the HSDPA-enabled UEs. To reduce the number of bits needed to transmit the additional control information, the HSDPA codes used with a particular modulation technique are allocated consecutively. For each modulation technique, only the beginning code and the total number of codes need be known to the UEs. The number of codes used with each modulation technique may be allowed to change once in several TTIs.

    摘要： Techniques for performing decision feedback equalization are described. A feed-forward filter response and a feedback filter response are derived based on a channel estimate and a reliability parameter and further without constraint on the feedback filter response or with a constraint of no feedback for an on-time sample. The reliability parameter is indicative of the reliability of the feedback used for equalization and may be frequency dependent or frequency invariant. Different feed-forward and feedback filter responses may be derived with different constraints on the feedback filter and different assumptions for the reliability parameter. Equalization is performed with the feed-forward and feedback filter responses. If equalization is performed for multiple iterations then, for each iteration, the reliability parameter may be updated, the feed-forward and feedback filter responses may be derived based on the updated reliability parameter, and equalization may be performed with the filter responses for the iteration.

    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.
