A method includes receiving an indication to transmit a first set of signals using a first standard (e.g., Long Term Evolution) via a first set of antennas of a radio frequency device and a second set of signals using a second standard (e.g., New Radio) via a second set of antennas. The method also includes transmitting the first set of signals via the first set of antennas using a first power based on positions of the first set and second set of antennas, exposure conditions of the first set and the second set of signals on a user, and/or priorities of the first and the second set of signals. Moreover, the method includes transmitting the second set of signals via the second set of antennas using a second power based on the positions of the antennas, the exposure conditions of the signals on the user, and/or priorities of the signals.

Systems, methods, and computer-readable media herein dynamically adjust the number of elements active within a neighboring base station in order to reduce the back lobe overlap and thus reduce the interference caused by such an overlap. User devices assigned to communicate with an antenna array are monitored to determine if they are experiencing a decreased level of performance which may be caused by an overlapping back lobe from a neighboring cell site. If the user device's performance falls below a threshold value, the gain associated with the neighboring cell site is dynamically reduced in order to reduce the back lobe overlap.

This application discloses a method for sending a physical uplink shared channel and an apparatus and relates to the communication field, to resolve a problem of how to transmit uplink data to different TRPs by using different precoding matrices. A network device sends indication information to a terminal device, where the indication information is used to indicate first information and second information. The first information is used to indicate first precoding information corresponding to a first nominal PUSCH repetition. The second information is used to indicate second precoding information corresponding to a second nominal PUSCH repetition. The terminal device sends N PUSCHs based on precoding information indicated by the indication information. The precoding information corresponding to the N PUSCHs includes at least one of the first precoding information and the second precoding information.
