Certain aspects of the present disclosure relate to a technique for communicating Channel State Information (CSI) feedback. In some aspects, the CSI feedback is communicated in a very high throughput (VHT) wireless communications system.

A computer-implemented reconstruction method of discrete digital signals in noisy overloaded wireless communication systems with CSI Errors that is characterized by a channel matrix of complex coefficients, the method including receiving the signal from channel by a signal detector, estimation of the CSI error parameter τ is done at the receiver, estimation noise power is done by a noise power estimator, forwarding the detected signal and the CSI error parameter τ and noise power estimation to a decoder that estimates the transmitted symbol, wherein the estimation of the decoder produces a symbol that could probably have been transmitted it is forwarded to a de-mapper, which outputs the bit estimates corresponding to the estimated transmit signal and the corresponding estimated symbol to a microprocessor for further processing.

First aperiodic zero power channel state information reference signal configuration information of a serving cell can be transmitted. Second aperiodic zero power channel state information reference signal configuration information of the serving cell can be transmitted. Downlink control information can be transmitted in a subframe of the serving cell. The downlink control information can include an aperiodic zero power channel state information reference signal indicator bit field that indicates a selection of one of at least the first aperiodic zero power channel state information reference signal configuration, the second aperiodic zero power channel state information reference signal configuration, and no aperiodic zero power channel state information reference signal in the subframe.

Systems, method and apparatus of managing wireless communication are described herein.

Disclosed are a dynamic configuration method, a terminal device, a network device and a computer storage medium. The method comprises: a terminal device receiving configuration information of at least two modulation and coding scheme (MCS) tables, wherein the configuration information is used for determining the at least two MCS tables; the terminal device receiving scheduling information sent by a network side; and the terminal device determining a target MCS table from the at least two MCS tables based on the scheduling information and the correlation between scheduling information and an MCS tables.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink control information (DCI) block including DCI for a set of transport blocks scheduled for the UE, the DCI including a set of fields. The UE may decode the DCI block to obtain the DCI for the set of transport blocks, where at least two fields of the downlink control information are jointly decoded according to an encoding scheme, and where each possible output of the encoding scheme corresponds to a jointly valid combination of the at least two fields. The UE may receive the set of transport blocks from a base station based on the DCI.

A non-orthogonal multiple access (NOMA) scheme data receiving method is provided. The method can comprise the steps of: receiving, by a user equipment (UE), downlink control information (DCI) for a NOMA scheme; receiving downlink data on the basis of the DCI; decoding interference data included in the received downlink data; cancelling decoded interference data in the received downlink data if the decoding is successful; and decoding the own downlink data remaining after the interference data has been cancelled.

A satisfactory list detection (LD) receiver based on spatial modulation (SM) orthogonal frequency division multiplexing (OFDM) waveform is provided. In some embodiments, the LD receiver can implement a suboptimal LD detection process that relies on a reduced search space an optimal joint ML detection-based process for the SM-OFDM transmission mode. In some aspects, the overall search space for the optimal joint ML is determined by the total spectral efficiency, which can be divided into two information categories with two different search spaces defined by the number of bits of each category. As such, in some aspects, the LD receiver can permit detecting, with reduced complexity, antenna bits and data bits based on a determination of respective log-likelihood ratios.

A receiver receives packets without prior knowledge of their bandwidths. The receiver calculates a first auto-correlation function for a first channel, a second auto-correlation function for a second channel, and a dot product of the first auto-correlation function and the second auto-correlation function. A packet is detected and its bandwidth classified based at least in part on the dot product.

Systems and methodologies are described that facilitate indicating a type of waveform utilized for uplink transmission in a wireless communication environment. An access terminal can select a type of waveform from a set of possible waveform types. Moreover, a reference signal can be generated based upon the selected type of waveform. For instance, a sequence employed to yield the reference signal can be generated and/or chosen as a function of the selected type of waveform. According to another illustration, a tone location and/or a symbol location of the reference signal can as part of the uplink transmission to the base station from the access terminal. The base station can detect the selected type of waveform utilized by the access terminal for the uplink transmission based upon parameter(s) recognized from the reference signal.
