摘要： Dynamic adjustment of antenna selection period at a wireless communication device or user equipment having two or more antennas. The described approaches consider an antenna selection performance metric. The antenna selection performance metric may include both measurement overhead (capacity loss due to measurements) and antenna switching capacity gain (gain in capacity through switching antenna subsets). The antenna selection performance metric may further include an estimate of UE speed or an antenna selection change rate. The antenna selection period may be adjusted by increasing or decreasing the antenna selection period based on the antenna selection performance metric. Antenna selection may be enabled or disabled based on the antenna selection performance metric.

摘要： Techniques for transmitting pilot and for processing received pilot to obtain channel and interference estimates are described. A terminal may generate pilot symbols for a first cluster in a time frequency block based on a first sequence and may generate pilot symbols for a second cluster in the time frequency block based on a second sequence. The first and second sequences may include common elements arranged in different orders and may be considered as different versions of a single sequence. The terminal may transmit the pilot symbols in their respective clusters. A base station may obtain received pilot symbols from multiple clusters in the time frequency block. The base station may form each of multiple basis vectors with multiple versions of the sequence assigned to the terminal and may process the received pilot symbols with the multiple basis vectors to obtain a channel estimate for the terminal.

摘要： Channel feedback reporting for non-orthogonal wireless communication systems employing frequency selective channels. A plurality of channel feedback matrices corresponding to a plurality of sub-carriers of a sub-band for a non-orthogonal channel may be determined by a UE, and one or more effective channel feedback matrices for the sub-band may be determined based on the plurality of channel feedback matrices. Each of the one or more effective channel feedback matrices may be associated with corresponding sets of transmission strategies, where each of the corresponding sets of transmission strategies include one or more transmission strategies of a plurality of transmission strategies for the non-orthogonal channel. Channel feedback information representing the one or more effective channel feedback matrices may be reported to a base station, which may estimate channel quality for the plurality of transmission strategies based at least in part on the channel feedback information, for downlink transmissions to UEs over the non-orthogonal channel.

摘要： System and method are disclosed for synchronization of a transmitting device and a receiving device that communicate with each other via pulse modulation. The synchronization technique entails the transmitting device sending one or more quasi-periodic pulse sequences to the receiving device. A quasi-periodic pulse sequence is based on a substantially periodic pulse sequence, and may include some non-periodic pulses or not include some periodic pulses. The transmitting device may transmit frames each including a preamble that comprises one or more quasi-periodic pulse sequences, and a data payload that may comprise data. The receiving device receives the signal, generates samples of the signal, and detects the quasi-periodic pulse sequences in the received signal by analyzing samples based on a sample associated with a pulse and the period associated with the substantially periodic pulse sequence. The receiving device is further able to detect frames based on the detection of the sequence, and extract data therefrom.

摘要： Various aspects of an approach for acquiring sequences such as balanced Hamming weight preamble sequences are described herein. The approach provides for the acquisition of preamble sequences base on energy accumulation. The approach includes creating a plurality of synchronization hypotheses, with each hypothesis being created based on energies sampled at a first location and a second location in a plurality of locations associated with a sequence of transmitted symbols; calculating a plurality of metrics based on the plurality of synchronization hypotheses, wherein each metric is associated with a hypothesis; selecting, as a candidate, one hypothesis from the plurality of synchronization hypotheses including a maximum associated metric. The approach may further include determining a boundary in the sequence of transmitted symbols based on a correlation property of the sequence of transmitted symbols. The second location includes a predetermined offset from the first location configured to provide enhanced interference immunity.
