Abstract: Methods, systems, and devices for interleaved mapping are described. In some implementations, a transmitting device identifies a set of virtual resource blocks (VRBs) corresponding to at least one code block to be transmitted to a receiving device. The transmitting device may determine that a quantity of VRBs to be transmitted to the receiving device is different than a quantity of entries within a regular interleaving matrix. Thus, the transmitting device may map each of the VRBs to a physical resource block (PRB) according to an irregular interleaving matrix to generate at least one interleaved code block. The transmitting device may transmit the interleaved code block to the receiving device. The receiving device may receive the interleaved code block and identify the PRBs associated with the interleaved code block. The receiving device may map each PRB within the interleaved code block to a VRB according to an irregular deinterleaving matrix.

Abstract: Methods and apparatuses for data aided channel quality estimation using both pilot and data information are disclosed herein. In one exemplary aspect, a method for estimating channel quality in a wireless communication system is disclosed. The method comprises estimating a pilot noise variance based on a pilot signal received from a base station on a downlink and estimating a data noise variance based on a data signal received from the base station on the downlink. The method also comprises combining the pilot noise variance and the data noise variance to obtain a combined noise variance, and estimating the channel quality based on the combined noise variance.

Abstract: Methods and apparatus for receiving, processing, and decoding MIMO transmissions in communications systems are described. A non-Gaussian approximation method for simplifying processing complexity where summations are used is described. Use of a priori information to facilitate determination of log likelihood ratios (LLRs) in receivers using iterative decoders is further described. A Gaussian or non-Gaussian approximation method using a priori information may be used to determine a K-best list of values for summation to generate an LLR is also described.

Abstract: Techniques for improved handoff searching in asynchronous systems, such as W-CDMA, are disclosed. In one aspect, a two-step search procedure is used when a list of neighbor codes is known. In the first step, a received signal is correlated with a slot timing code to locate on or more pilots and the slot boundaries associated therewith. In the second step, the received signal is correlated with each of the list of codes at the slot boundaries identified with pilots in the first step to identify the pilot code and the frame timing associated with each pilot. Various other aspects of the invention are also presented. These aspects have the benefit of decreasing search time, which translates to increased acquisition speed, higher quality signal transmission, increased data throughput, decreased power, and improved overall system capacity.
