摘要： Methods, devices and computer program products are provided to improve uplink communications in a wireless communication system. Reference symbols in an uplink transmission radio subframe are time-frequency multiplexed with additional data symbols. The multiplexed data symbols are transmitted in an uplink transmission to another device within the wireless communication network along with non-multiplexed data symbols. The multiplexing operations enable the transmission of additional data symbols without increasing the overhead associated with the transmission of symbols in the radio subframe.

摘要： A method of wireless communication is disclosed which includes acquiring a first set of precoding matrices for a set of frequency bands and generating a second set of precoding matrices for the set of frequency bands based on the first set of precoding matrices. The second set of precoding matrices enables a transmission that satisfies a cubic metric criteria in multiple-in multiple-out communication mode in the uplink. In some designs, generating the second set of precoding matrices can be based on restricting the first set of precoding matrices for a set of frequency bands and transmission rank, rotating the first set of precoding matrices based for a predetermined transmission rank, or a combination thereof.

摘要： Systems and methods are described herein for transmitting uplink SC-FDMA symbols. When an extended cyclic prefix is used, the symbols are divided into pairs, and the first symbol and a function of the second symbol in each pair is transmitted via a first antenna and the second symbol and a function of the first symbol in each pair is transmitted via a second symbol. When an unpaired symbol remains, the unpaired symbol is divided into halves, and a first function of the halves is transmitted on the first antenna and a second function of the halves is transmitted on the second antenna.

摘要： User equipment (UE) associated with synchronous networks operate in a synchronous mode while UEs associated with asynchronous networks operate in an asynchronous mode. When operating in a synchronous mode, a UE can significantly improve performance of synchronization signal detection, data decoding, and tracking loop management by using the interference cancellation (IC) techniques that are not available in an asynchronous mode of operation. Obtaining synchronization indicators and determining the synchronization status of the current network by UE is disclosed. The determination may be based on the synchronization indicator, whether detected through signal detection, signal measurements, signal analysis, or the like.

摘要： A system and method for facilitating resource management in OFDM systems is provided. The system permits different and flexible resource cell metric operations levels (e.g. uplink load management, admission control, congestion control, signal handoff control) for different sub-bands. For the uplink load management, there are multiple distinct load operation points (e.g. IoT, RoT) per sub-band group instead of the same operation level across the entire available band. The sub-band groups encompass the entire band. The facilitation system also comprises a variety of transmitting protocols, command increment variable stepsize methods and robust command response methods. The system thus provides more flexible reverse link resource management and more efficient utilization of the bandwidth.

摘要： Methods and apparatus for selecting samples for secondary synchronization signal (SSS) detection are described. Several alternatives are provided for efficient cell identifier detection. In a first alternative, multiple bursts of a signal received from a cell are sampled with non-uniform spacing between sampling intervals to determine a sequence for cell identification. In a second alternative, samples of a first and a second signal received from a stronger cell are cancelled, and a sequence for detecting a weaker cell is determined by reducing effects of the samples of a third signal received from the weaker cell which do not overlap with the primary synchronization signal (PSS) or SSS of the stronger cell. In a third alternative, a sequence for detecting a weaker cell is determined by reducing effects of any sampled bursts that correspond to a high transmission power portion of a signal from a stronger cell.
