A transceiver for transmitting and receiving full duplex communications includes transmitter and receiver circuitry. The transmitter circuitry transmits from a first location first signals having a first orthogonal function +l.sub.n applied thereto on a first channel on a first frequency band to a second location. The receiver circuitry receives at the first location second signals on a second channel on the first frequency band from the second location having a second orthogonal function −l.sub.n applied thereto and the first signals having the first orthogonal function +l.sub.n applied thereto on the first channel on the first frequency band from the first location at a same time on the first frequency band. The receiver circuitry only processes received signals including the second orthogonal function −l.sub.n. The first signals on the first channel are transmitted on the first frequency band on the first frequency band at a same time the second signals on the second channel are received on the first frequency band on the first frequency band.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may obtain an indication of an overlap between a plurality of sidelink communications. The mobile station may detect a conflict between the plurality of sidelink communications having the overlap based at least in part on whether the plurality of sidelink communications are intended for an interference cancellation capable receiver mobile station. Numerous other aspects are described.

In some embodiments, a method for mitigating interference in a channel having multiple users can include: determining a starting angle based on a direction of a signal of interest (SOI); iteratively steering a beam away from the starting angle in opposite directions and calculating a grade of the beam; choosing the beam at a current angle as a receive beam based on the beam grade; receiving a signal using the receive beam; and decoding the SOI from one or more interfering signals using successive interference cancellation multi-user detection (SIC MUD) on the received signal.

The present disclosure discloses a method and a system for providing a code cover to Orthogonal Frequency Division Multiplexing (OFDM) symbols in a multiple user system. A data sequence is received from each of a plurality of users. Further, a reference sequence is generated for the data sequence of each of the plurality of users. Each of the reference sequence is multiplied with a code cover which are orthogonal to each other. Each of the reference sequence is time-multiplexed with corresponding data sequence, to generate a corresponding multiplexed sequence. Further, a Discrete Fourier Transform (DFT) is performed on each of the multiplexed sequence to generate a corresponding DFT-spread-Orthogonal Frequency Division Multiplexing (DFT-s-OFDM) symbol. Lastly, the corresponding DFT-s-OFDM symbol is processed for transmitting over corresponding one or more channels.

A multiple access slotted wireless communication system comprising a plurality of terminals and a multi-access receiver is described. The multi-access receiver can decode multiple transmissions in each slot of a frame from terminals in its field of view. Each terminal has an active state for transmitting and an inactive state. After receiving acknowledgement of a successful transmission by the terminal, the terminal enters the inactive state for at least a transmission delay time. This may be the remaining time that the terminal is in the field of view of the multi-access receiver. This may be achieved by the terminal using a probability of transmission to determine whether or not to transmit in the next frame. The terminal may also be configured to select the slot in a frame, and this may be based upon information such as which slots were acknowledged. The receiver may use compression to transmit acknowledgement messages.

Provided is a method for a terminal for transmitting uplink control data. The method includes receiving, from a base station, at least one of UL control channel resource set configuration information and UL control channel transmission information, configuring an UL control channel including the UL control information based on at least one of the UL control channel resource set configuration information and the UL control channel transmission information, and transmitting the UL control channel to the base station. The UL control channel is configured with one or more UL control channel formats based on the number of symbols that configure the UL control channel.

Embodiments of this disclosure include apparatuses and methods for data channel mapping type and demodulation reference signal (DM-RS) configuration to enable a physical layer (L1) crosslink interference (CLI) measurement and reporting. Some embodiments are direct to a method of operating a base station (BS), where the method can include generating, by the BS, a demodulation reference signal (DM-RS), determining, by the BS, a position of the DM-RS in a first transmission slot, transmitting, by the BS, the DM-RS to a UE based on the determined position in the first transmission slot, processing, by the BS, a crosslink interference (CLI) measurement fed back based on the DM-RS, wherein the CLI measurement fed back is in a channel state information (CSI) report, and performing, by the BS, a CLI mitigation based on the CLI measurement.

Disclosed is a device discovery method, comprising: a terminal device sending a target sequence on a first time-frequency resource by means of a first antenna port, wherein the target sequence is used for implementing D2D discovery; and the terminal device detecting, while sending the target sequence, a first sequence on the first time-frequency resource by means of a second antenna port, wherein the first sequence and the target sequence are sequences, having autocorrelation and cross-correlation attributes, in a first sequence group. Also disclosed are a terminal device and a storage medium.

An apparatus may include at least one processor and at least one memory including computer program code. The at least one memory and the computer program code can be configured to, with the at least one processor, cause the apparatus to at least apply at least one orthogonal cover code to at least a first antenna port and a second antenna port. The at least one memory and the computer program code can be further configured to, with the at least one processor, cause the apparatus to at least perform at least one rotation operation associated with at least one signal of the first antenna and the second antenna. The apparatus is caused to at least perform at least one channel estimation based upon the at least one signal of the first antenna and the second antenna.

Embodiments of the invention are directed to a cellular communication network that can determine whether communications between one base station-UE pair may interfere with another UE that is in the same cell or a different cell. The network identifies interference parameters associated with interference signals that may be received by a UE. The interference signals may be generated by the base station itself, such as communications with other UEs, or by a neighboring base station. The base station transmits the interference parameters to the UE. The UE receives the one or more parameters comprising information about signals expected to cause intra-cell or inter-cell interference. The UE then processes received signals using the one or more parameters to suppress the intra-cell or inter-cell interference.
