摘要:
Systems and methodologies are described that facilitate adjusting power spectrum density (PSD) for wireless devices according to multiple possible step sizes. A step size for an adjustment can be selected based at least in part on a received overload indicator from one or more access points, a PSD required to achieve a target signal-to-interference-and-noise ratio (SINR) for a wireless device, and a PSD previously assigned to the wireless device. Once the step size is selected, it can be applied to the previous PSD to generate a new PSD for the wireless device, and the wireless device can accordingly adjust PSD to mitigate inter-cell interference with the one or more access points.

Wireless uplink communication is disclosed which includes dividing information bits into first and second sets of information bits. The first set of information bits is encoded into a first set of coded bits, while the second set of information bits is encoded into a second set of coded bits. The first and second sets of coded bits are rate matched into a defined number of bits generating first and second sets of rate-matched coded bits. The first and second sets of rate-matched coded bits are interleaved using various interleaving methods to generate an interleaved set of coded bits.

A method for transmitting a channel quality indicator-only feedback payload is described. A channel quality indicator scheduling message is received from a base station. A channel quality indicator-only feedback payload is generated. The channel quality indicator-only feedback payload is transmitted on a physical uplink shared channel. The method may be performed by a wireless communication device.

Techniques for acknowledging data transmissions in a multi-carrier wireless communication network are disclosed. In one aspect, a UE determines a number of acknowledgement/negative acknowledgement (ACK/NACK) bits for a data transmission on one more component carriers (CCs) based on information obtained from a grant. The grant may be a downlink grant or an uplink grant, and the information obtained may include a number of CCs scheduled for data transmission and/or identifiers of the scheduled CCs. The UE may determine the number of ACK/NACK bits for acknowledging the data transmission based on the number of scheduled CCs and the identifier of each scheduled CC.

A method of wireless communication includes determining a number of symbols for uplink control information (UCI) on each of a plurality of layers, multiplexing symbols for the UCI with data on multiple layers such that the symbols are time aligned across the layers, and sending the multiplexed symbols on the multiple layers on uplink. In some designs, the number of symbols for the UCI may be determined based on a spectral resource parameter.

Certain aspects of the present disclosure relate to techniques for indicating downlink assignments to a user equipment (UE). According to certain aspects, the techniques generally involve generating a downlink assignment index (DAI) indicating a number of assigned downlink transmissions for a user equipment (UE) configured to communicate using multiple component carriers and transmitting a physical downlink control channel (PDCCH) containing the DAI to the user equipment (UE) in a frequency division duplexing (FDD) subframe in which uplink and downlink transmissions may take place at the same time on different carrier frequencies.

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:
Systems and methodologies are described that facilitate cycling through precoders for transmitting wireless network communications in a time domain. The precoders can be cycled according to a precoder sequence for each data symbol transmission. When the last precoder is selected the cycle can begin again, a new precoder sequence can be received or defined, and/or the like. A precoder sequence related to a subset of precoders present in a wireless device can be defined sequentially, cyclically shifted according to an identifier or one or more communications parameters, randomly, pseudo-randomly according to an identifier or one or more communications parameters, and/or the like. In addition, the precoder sequence can be utilized to select a precoder for one or more retransmissions. Such cycling of precoders can increase transmit diversity.
