Further, the MISO operator is configured to generate an output signal with an amplitude or a phase controlled by at least one of the amplitude control signals, the phase control signals and the power supply signal.

Methods, systems, and devices for wireless communication are described. A network device, such as a base station, may transmit a request message to a user equipment (UE). The request message may include a request for the UE to transmit a set of sounding reference signals (SRSs). The set of SRSs may include two (or more) beamformed signals. The network device may receive the set of SRSs according to the request message. The network device may identify, based on a co-phasing parameter associated with the two (or more) beamformed signals, an antenna port precoder configuration to use for communicating with the UE.

Embodiments of the present disclosure disclose an uplink transmission method, an uplink transmission scheduling method and a device. The uplink transmission method is applied to a terminal and includes: performing delay processing of an uplink signal on multiple antenna ports and then transmitting the uplink signal.

The method for reporting terminal information includes: transmitting a setting parameter of an antenna structure of a terminal to a base station, where the setting parameter includes a radio frequency parameter; where the radio frequency parameter includes one or more of: a quantity of panels, frequency information supported by each panel, a quantity of beams supported by each panel, and a quantity of antenna array polarization directions of each panel.

A method for sidelink groupcast transmission, performed by a transmitting terminal, may comprise configuring a first feedback resource located at a first time point and a second feedback resource located at a later time point than the first time point; transmitting groupcast control information and groupcast data to a receiving terminal group; receiving first feedback information through the first feedback resource from at least one terminal belonging to a first subgroup of the receiving terminal group; and receiving second feedback information through the second feedback resource from at least one terminal belonging to a second subgroup of the receiving terminal group.

A wireless communication apparatus is capable of improving communication efficiency by reducing the amount of control information transmitted. A channel quality information extraction section extracts CQI's from a received signal. An allocation control section allocates subcarriers for every communication terminal apparatus and selects a modulation scheme in such a manner that required transmission rate is satisfied for each communication terminal apparatus based on required transmission rate information, etc. and CQI's for communication terminal apparatus of each user. A required subcarrier number determining section decides the number of subcarriers allocated to every communication terminal apparatus so as to satisfy the required transmission rate for each communication terminal apparatus. A required subcarrier number information generating section generates information for the number of subcarriers allocated to every communication terminal apparatus. A subcarrier allocation section allocates packet data to selected subcarriers. Modulating sections adaptively modulate packet data allocated to each subcarrier.

An example method may include configuring a pattern of a sounding packet of a first wireless node in a resource space. Configuring the pattern may include assigning first precoders to a first subset of the resource space for a first antenna sector of the first wireless node; and assigning second precoders to a second subset of the resource space for a second antenna sector of the first wireless node. The method may include wirelessly transmitting the sounding packet with the configured pattern to a second wireless node. The method may include transmitting data packets from the first wireless node to the second wireless node according to one or more transmission parameters that are at least one of received from the second wireless node or determined based on channel state information (CSI) feedback received from the second wireless node.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a set of recommended base station transmit beams for full duplex operation based at least in part on measurements of a set of base station transmit beams and measurements of self-interference associated with the set of base station transmit beams. The UE may transmit a report that indicates a recommendation to use one or more of the set of recommended base station transmit beams for full duplex operation. Numerous other aspects are described.

Disclosed are a method and a device for managing a beam in sidelink communication. An operation method of a first terminal comprises: a step for transmitting a first sidelink signal in all directions using a beam sweeping method in an initial beam management section; a step for receiving, from a second terminal, first feedback information for the first sidelink signal; a step for setting a first beam pair between the first terminal and the second terminal on the basis of the first feedback information; a step for performing sidelink communication with the second terminal using the first beam pair; and a step for, when it is necessary to reset the first beam pair, transmitting the second sidelink signal in a specific direction instead of all the directions using the beam sweeping method in a partial beam management section. Therefore, the performance of a communication system can be improved.

A method is disclosed of a transmitter configured to transmit one or more physical layer packets, which together have a plurality of measurement signals for channel estimation. The method includes receiving (from a sensing device) a precoding setting request for the measurement signals for channel estimation, wherein the precoding setting request is indicative of one or more precoding settings prioritized for sensing, configuring the transmitter to use precoding settings for the plurality of measurement signals for channel estimation based on the precoding setting request, and transmitting the one or more physical layer packets. A method is also disclosed of a receiver configured to operate as a sensing device.
