    摘要: Providing for noise estimation in wireless communication, and particularly for access request signals transmitted by a user equipment (UE), is described herein. By way of example, a wireless signal receiver can employ unused signal dimensions of a wireless network for noise estimation. In addition, the unused signal dimensions can be selected for time-frequency resources that are associated with a particular wireless channel, in order to obtain a noise estimate for that channel. By employing unused signal dimensions, a noise measurement is likely to include no other signal transmissions, and provide an accurate estimate of noise on that channel. According to various aspects of the subject disclosure, one or more Chu sequences employed for signal transmissions, root sequences thereof, or one or more cyclic shifts of a root sequence can be employed for the unused signal dimension.

    摘要: A method for transmitting an acknowledgement/negative acknowledgement is described. Cell-specific symbol-level cyclic shift hopping is applied to data single-carrier frequency division multiplexing symbols of the acknowledgement/negative acknowledgement. A discrete Fourier transform is applied to the data single-carrier frequency division multiplexing symbols. Cell-specific symbol-level phase hopping is applied to the data single-carrier frequency division multiplexing symbols. The data single-carrier frequency division multiplexing symbols are transmitted in a slot.

    摘要: 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.

    摘要: Certain aspects of the present disclosure provide an apparatus and techniques for efficiently processing uplink communications. A telecommunications receiver processor architecture is provided that may be utilized with a LTE eNodeB base station wherein the data path throughput is optimally matched for a Physical Uplink Shared Channel (PUSCH) receiver. According to certain aspects, the receiver may be configured to perform operations on OFDMs symbols in an interleaved order. Additionally, the receiver may instantiate multiple IDFT engines to process multiple OFDM symbols in parallel.
