    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.

    摘要: Certain aspects of the present disclosure relate to a method and apparatus for processing wireless communications. According to certain aspects, a linked list of chunks of memory used to store logarithmic likelihood ratio (LLR) values for a transport block is generated. Each chunk holds LLR values for a code block of the transport block. The linked list is then provided to a hardware circuit for traversal. According to certain aspects, the hardware circuit may be an application specific integrated circuit (ASIC) processor or field programmable gate array (FPGA) configured to traverse the linked list of chunks of memory used to store LLR values.

    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: 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.
