A method of wireless communication by a first user equipment (UE) includes receiving a vehicle-to-everything (V2X) message from a second UE. The method also includes periodically transmitting and receiving a radar signal to sense an environment of the first UE. The method includes estimating joint communication and radar side information based on the V2X message and the radar signal. The method further includes predicting a communication state between the first UE and the second UE based on the joint communication and radar side information. The method still further includes updating communication transmit parameters based on the communication state.

Embodiments of the present invention provide an uplink control information sending method, an uplink control information receiving method, an apparatus, and a system. The method includes: receiving, by a terminal device, channel indication information from an access network device on a physical control channel; determining the channel resource set that is of N channel resource sets and that matches a type or a size of the UCI as a first channel resource set; determining a channel resource that is in the first channel resource set and that is indicated by the channel indication information; and sending uplink control information UCI to the access network device on the channel resource. A quantity of bits that need to be added to the channel indication information in the embodiments of the present invention is less than that in the prior art.

A method and apparatus are disclosed herein for controlling transmit power in a station (STA) of a wireless local area network (WLAN). A STA may transmit, to another STA, transmit power step size information that indicates a maximum transmission power for an operational bandwidth that the STA supports. The STA may receive, from another STA, a signal in one of the plurality of operational bandwidths that the STA supports. The received signal may include a transmission power based on the transmitted adjustment step size setting.

In a communication device, a multi-carrier signal with at least one group of signal carriers is received from a communication connection. For each of the signal carriers, at least one individual error value is evaluated or generated. From the individual error values, a combined error value is evaluated or generated. The combined error value is transmitted on a backchannel of the communication connection.

A wireless communication device transmits data to multiple wireless terminals at the same timing. The wireless communication device includes a complement calculation part configured to calculate the amount of complement for transmission data for each wireless terminal among multiple wireless terminals on multiple subcarriers distributed and assigned thereto, a complementation part configured to complement transmission data using the amount of complement calculated for each wireless terminal, and a transmitter configured to transmit the complemented transmission data to multiple wireless terminals via multiple subcarriers. The wireless communication device further includes a frame generator configured to generate frames (e.g. OFDMA frames) used to multiplex and transmit the complemented transmission data to multiple wireless terminals. The complement calculation part calculates the amount of complement based on the number of available subcarriers, which is determined via carrier sensing.

A communications device transmitting/receiving signals to/from a mobile communications network includes one or more network elements providing a wireless access interface for the communications device. The wireless access interface includes plural communications resource elements across a host frequency range of a host carrier, and a first section of the communications resources within a first frequency range for preferable allocation to reduced capability devices forming a first reduced bandwidth carrier and a second section of the communications resources within a second frequency range for preferable allocation to the reduced capability devices forming a second reduced bandwidth carrier. Each of the first and second frequency ranges is within the host frequency range. The communications device is configured with a reduced capability to receive the signals only within a frequency bandwidth less than the host frequency range and equal to at least one of the first frequency range or the second frequency range.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information (DCI) that schedules an uplink communication in an uplink frequency band. The UE may transmit, at an uplink frequency within the uplink frequency band, the uplink communication with a power that varies over the uplink frequency band based at least in part on a location of the uplink frequency relative to a downlink frequency band associated with the UE. Numerous other aspects are provided.

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for a user equipment (UE) entering a dormant state with respect to a secondary cell group (SCG) of a node network (SN) having a primary serving cell (PSCell). In one aspect, the UE may maintain a parameter set for at least the PSCell while the UE is in the dormant state with respect to the SCG. For example, the UE may receive a parameter change message from either the SN or a master network (MN) and transmit a parameter change acknowledgment to either the SN or the MN. The parameter change message may be transmitted as one or both of a downlink control information (DCI) or media access control (MAC) control element (CE). The UE may transmit physical layer measurements to the SN based on the parameter set.
