摘要： Systems and methodologies are described that facilitate implementing a linear adaptive equalizer receiver on the downlink link of a UMTS TDD wireless communication system. A reference signal can be generated based on multiple non-common midamble sequences in a time slot of a received transmission. Traffic-to-pilot ratios for channel codes in the time slot can be generated, and relative strengths of channel codes associated with specific midambles can be determined to weight the midamble. A plurality of the weighted midambles can then be utilized to generate a reference signal to train the equalizer, which can facilitate utilization of total aggregate midamble energy rather than midamble energy associated with a single midamble in the signal.

摘要： Methods, apparatuses, and computer program products are disclosed for facilitating multicarrier channel quality indicator (CQI) feedback. A wireless terminal communicates with a base station via a plurality of carriers and receives configuration data generated by the base station identifying a subset of carriers included in the plurality of carriers. The wireless terminal identifies a reference carrier and reports a reference CQI value corresponding to the reference carrier to the base station. The wireless terminal also reports a differential CQI value derived from the reference CQI value to the base station.

摘要： Systems and methodologies are described that facilitate defining new control channels in legacy wireless networks. Control data resources for new systems can be defined over resources reserved for general data communications in the legacy wireless network specification. In this regard, legacy devices can still be supported by devices implementing new control data resources, and the new control data resources can avoid substantial interference that is typically exhibited over legacy control and/or reference signal resources by instead using the general data resources. In addition, new system devices can avoid scheduling data communication resources over the new control resources to create a substantially non-interfered global control segment. Control data can be transmitted over the segment using beacon-based technologies, reuse schemes, and/or the like.

摘要： Techniques are discussed herein identify transmission strategies and to communicate those identified transmission strategies in a transparent communication environment. In some examples, a user equipment (UE) may identify a new transmission strategy for a downlink channel different from a current transmission strategy for the down link channel. The UE may transmit a channel state information (CSI) message that includes an indication of the new transmission strategy identified by the UE. In some examples, a base station may identify the new transmission strategy for the downlink channel. The base station may transmit a codebook subset restriction (CSR) indicator that includes an indication of the new transmission strategy identified by the base station. In some examples, the UE may modify its feedback strategy based on the new transmission strategy.

摘要： A wireless communication network distributes resources for a Physical Downlink Control CHannel (PDCCH) over multiple carriers in accordance with a constraint that limits a number of blind decoding actions required by user equipment (UE). Distribution can entail segregating UE-specific and common search spaces to different monitored carriers. Distribution can entail segregating aggregation levels to different monitored carriers. Distribution can entail segregating a number of decoding candidates for a given aggregation level to different monitored carriers. The distribution can be orthogonal or non-orthogonal, and can be UE-based or per cell-based. The distribution can be static, semi-static or hop with time.

摘要： Techniques for sending ACK/NACK information in a multi-carrier wireless communication network are disclosed. In one aspect, a plurality of ACK/NACK transmission techniques are selectively employed by a multi-carrier user equipment (UE) to reduce the number of bits of ACK/NACK information to send and/or increase the number of payload bits available for sending the ACK/NACK information. The ACK/NACK transmission techniques may include an orthogonal sequence reduction technique, a channel selection technique, a spatial bundling technique, a carrier bundling technique, and/or a subframe bundling technique. The ACK/NACK transmission techniques may be prioritized based on the number of carriers on which data transmissions are received, a payload size available for carrying ACK/NACK information, and/or other factors. The multi-carrier UE can utilize different ACK/NACK transmission techniques in connection with different subsets of its configured carriers.

摘要： The described aspects include methods and apparatus for communicating control information in a carrier aggregation configuration that uses multiple radio access technologies (RAT). A first resource assignment related to a first carrier corresponding to a first RAT can be received, as well as, a second resource assignment related to a second carrier corresponding to a second RAT. The first carrier and the second carrier are aggregated for communicating data in a wireless network. In addition, resources can be determined for communicating first RAT control data for the first RAT over an uplink carrier based at least in part on the first resource assignment. Second RAT control data can then also be communicated in containers and/or using timing for control data of the first RAT over at least a portion of the resources.
