Methods, systems, and devices for wireless communication at a user equipment (UE) are described. A UE may establish a wireless connection with a primary cell and may identify a set of antenna modules of the UE and multiple sets of receive beams. Each set of receive beams may include at least one beam from each antenna module. The UE may perform a measurement procedure on signals received from one or more candidate secondary cells using at least a first set of receive beams. The UE may then transmit, to the primary cell, a measurement report based on performing the measurement procedure upon determining that at least one of the multiple sets of receive beams satisfies a threshold value and before performing the measurement procedure on signals received from the one or more candidate secondary cells using at least one remaining set of receive beams.

An antenna adaptation is provided for a communication node as controlled by a antenna adaptation command. The antenna adaptation command adjusts the number of active transmit antennas and/or the number of active receive antennas in the communication node such as for reducing interference at the communication node.

A wireless communication device may receive with one of N antennas a signal processing message indicating a number up to N signals to process. Each of the N antennas may used to receive a communication. The indicated number of up to N signals may be processed and data from the indicated number of up to N signals recovered.

An apparatus, comprising: means for obtaining radio environment information related to at least one downlink signal received by a user equipment using at least one currently-active reception antenna panel of a plurality of selectively-activatable reception antenna panels; and means for reconfiguring at least one of the plurality of selectively-activatable reception antenna panels to be used for performing radio measurements of a downlink signal to be one of active and inactive in response to a variation in the radio environment information.

A method and apparatus for random access indication. The serving base station sends a random access indication signaling to a terminal. The random access indication signaling is configured to indicate, to the terminal, a target antenna panel and/or a target beam for sending a random access preamble. The terminal receives the random access indication signaling, and determines, according to the random access indication signaling, the target antenna panel and/or target beam for sending the random access preamble.

Aspects described herein relate to activating, at a user equipment (UE), a first set of antennas or associated communication resources of the UE to measure a first synchronization signal block (SSB) for synchronizing communications in a first connected mode discontinuous receive (CDRX) period without activating a second set of antennas or associated communication resources of the UE to measure a second SSB, and activating, at the UE, the second set of antennas or associated communication resources of the UE to measure a second SSB for synchronizing communications in a second CDRX period without activating the first set to measure the first SSB.

To schedule panel specific uplink transmissions, the UE may assist in the scheduling of the panel specific uplink transmission by improving the manner in which the specific panel is indicated for uplink transmission. The apparatus receives, from a base station, an indication of a UE panel for an uplink transmission. The apparatus determines a Tx panel at the UE based on the indication of the UE panel. The apparatus transmits, to the base station, the uplink transmission using the Tx beam associated with the Tx panel.

By a transmission method according to one aspect of the present disclosure, in a broadcasting system that generates a first broadcasting signal and a second broadcasting signal by performing multi-antenna encoding on program data, and wirelessly transmits a first broadcasting signal and a second broadcasting signal, a first transmit station transmits the first broadcasting signal, a second transmit station transmits the second broadcasting signal, the first transmit station and the second transmit station transmit the first broadcasting signal and the second broadcasting signal to an overlapping area at an identical time using an overlapping frequency band, polarized wave transmitted from the first transmit station differs from polarized wave transmitted from the second transmit station, and arrangement of the first transmit station differs from arrangement of the second transmit station.

An electronic device, according to various embodiments of the present invention, is disclosed, comprising: an antenna array including a plurality of antenna elements disposed at intervals of a first distance; and a communication circuit electrically connected with the antenna array, wherein the communication circuit is configured to: supply power to a first antenna element and a second antenna element spaced apart from the first antenna element by a second distance among the plurality of antenna elements; form a beam comprising a main lobe and a grating lobe having a predetermined angle with the main lobe, by using the first antenna element and the second antenna element; and sense an RF signal incident from the outside by using the formed beam. Various other embodiments inferred from the present specification are also possible.

This application provides a method for adjusting a half-power angle of an antenna, to adjust a maximum half-power angle or a maximum beam gain of an individual transceiver channel. The method includes: first determining that M antenna elements in N antenna elements connected to a first transceiver channel of an access network device need to be turned on or off, where N>M≥1, and both N and M are integers, that is, a quantity of antenna elements driven by the first transceiver channel needs to be adjusted; and then sending first indication information to the access network device, where the first indication information is used to indicate to turn on or off the M antenna elements.
