    摘要： Methods, systems, and devices are described for reference signal design in wireless communications. A base station may select a reference signal density scheme from a set of available density schemes associated with a port count. The reference signal density scheme may also be selected based on the category of the mobile device receiving the reference signal transmissions. The reference signal density scheme may be a higher density reference signal density scheme or a lower density reference signal density scheme, where the higher density reference signal density scheme includes more reference signal resource elements per subframe. The mobile device may determine the reference signal density scheme based on characteristics of a channel. The higher density reference signal density scheme may provide additional channel estimation opportunities for the mobile device. In some cases, the mobile device sends the channel estimated based on the received reference signals to the base station.

    摘要： A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus generates a data transport block, divides the data transport block into a number of sub-blocks. The sub-blocks include at least a first sub-block and a second sub-block, where a size of the first sub-block is different than a size of the second sub-block. The apparatus may encode the number of sub-blocks using different code rates and/or different coding schemes. The apparatus may modulate the encoded sub-blocks using different modulation orders. The apparatus transmits the sub-blocks to a receiver.

    摘要： Methods and apparatus for initial acquisition gain control in a communication system a method for use in a wireless communication system are disclosed. A disclosed methodology includes measuring the power of a signal received by a transceiver a number of times over a prescribed time period, the signal including a number of symbols. A gain of the transceiver is unidirectionally adjusted when a currently measured power is greater than a previously measured power during the prescribed time period until a maximal power level is measured. By adjusting the gain to accommodate a maximal power value, which is the same as the power level of an acquisition pilot symbol, overshoot and distortion by the transceiver are avoided during initial timing and frequency acquisition. Corresponding apparatus are also disclosed.

    摘要： Apparatus and methods for determining timing tracking in a multiple antenna wireless system are disclosed. Timing tracking is obtained, in particular, by determining at least two channel density profiles for signals respectively received by at least two antennas of multiple receive antenna wireless device. The channel density profiles are then combined, such as by summing, to form a composite channel density profile. The composite is, in turn, used by a timing tracking algorithm to determine a timing decision for setting the timing tracking in a transceiver device used in the multiple antenna wireless system. Use of a composite density profile affords the system increased resistance to channel dynamics such as fading, birth and death, which reduces degradation due to mistiming caused by such channel dynamics.

    摘要： Method and apparatus for progressive preamble transmission in a communication system, such as a wireless system, is disclosed. In particular, a first symbol is utilized to communicate first timing information for coarse timing acquisition. A second symbol communicates first information including network identification information concerning a first network for fine timing acquisition of symbols in the first network. If a second network data is desired, a progressive or selectively utilizable third symbol communicates second information including network identification information concerning a second network. The network identification information concerning the second network includes network identification information concerning the first network to minimize processing to determine fine timing acquisition for the second network data.

    摘要： Base stations (such as small cells) may support active and dormant states. To facilitate state transitions, these cells may transmit discovery signals. The transmission design of both discovery signals and network synchronization signals from small cells should provide for regular periodicity, while supporting the benefit of transitioning between active and dormant states. Disclosed is a method, a computer program product, and an apparatus that determine a first reference signal for at least one of discovery or measurement, and a second reference signal for synchronization, where both the first reference signal and the second reference signal are based on a same type of reference signal.
