摘要： Systems and methodologies are described that facilitate precoding signals transmitted over downlink control channels to provide transmit diversity. A dedicated reference signal (DRS) related to a wireless device can additionally be precoded such that the wireless device can determine a precoder or related parameters based at least in part on performing a channel estimate for the precoded DRS signal. The wireless device can utilize the determined precoder or related parameters to decode precoded signals received over downlink control channel resources. Additionally or alternatively, an access point can signal a sequence of precoders to the wireless device. The access point can cycle through the sequence of precoders to precode signals for transmission over downlink control channel resources, and the wireless device can decode the signals based at least in part on similarly cycling through the precoders for received signals.

摘要： Systems and methodologies are described herein that facilitate processing and pruning of blind decoding results (e.g., associated with grant signaling) within a wireless communication environment. As described herein, blind decoding results associated with grant signaling and/or other suitable signaling can be pruned in various manners, thereby reducing false alarm probabilities associated with such results. For example, techniques are provided herein for constraining respective decoding candidates to possible radio network temporary identifier (RNTI) values, performing validity checking on payload of respective decoding candidates, and selecting a most likely decoding candidate from a previously pruned set of candidates. Further, techniques are described herein for generating filler bits (e.g., padding bits, reserved bits, etc.) in a grant message according to a predefined pattern, thereby enabling checking of such bits to further reduce false alarm rates.

摘要： An enhanced random access procedure for current (e.g. Release 8, ReI. 8) and future (e.g. Release 9, ReI. 9 and beyond) versions of user equipment (UE) communicating with base stations (eNB). A random access preamble is transmitted, wherein the random access preamble comprises release version information of a user equipment. A payload portion of a random access response is derived (decoded), and a contention resolution message is received. The base station (eNB) may determine the release version of the UE transmitting the random access preamble (e.g. if the release version is sent on the random access preamble), and will select one or more (i.e. a set of group of) Random Access Channel (RACH) sequences from a set of RACH sequences based on the release version of the UE and will generate a random access response. The base station will transmit the random access response using a first scheme.

In one scheme, a filter selection metric is determined for a signal to be recovered, a channel estimation filter is selected based on the filter selection metric, and a channel estimate is derived with the selected channel estimation filter.

A second channel estimate is derived with a second channel estimation filter having a second filter response that is different from the first filter response.
