The present disclosure relates to systems and methods for operating a control signal to communicate signals using a first antenna and a first frequency band in response to determining that intra-device operations are occurring or are expected to occur, that a first amount of energy received by the first antenna is less than a threshold amount of energy, and that the first antenna is unaffected by the intra-device operations. The control signal may also delay communication of the signals in response to determining that intra-device operations are occurring, and that first amount of energy is greater than or equal to the threshold amount of energy.

Listen-before-talk systems, devices, and methods based on intra-device operations

Multi-radio wireless network devices are capable of transmitting and/or receiving data from multiple radiofrequency (RF) networks at different bands. Total transmission power limitations may be in place due to, for example, safety reasons. As a result, active management of transmission power may be performed during simultaneous transmission in different bands and/or networks. In some embodiments, the management may take place on group-by-group basis and a network-by-network basis. Antennas may be grouped based on their relative positions and impact on radiation emitted by the devices.

Granular adjustment of antenna power in multi-radio systems

A device and method selects an antenna configuration. The method performed at a user equipment includes determining at least one communication functionality that is being used, each communication functionality configured to utilize at least one antenna in a multi-antenna arrangement of the user equipment. The method includes receiving a first indication of whether a cellular communication functionality is being used, the cellular communication functionality configured to utilize at least one antenna in the multi-antenna arrangement. The method includes receiving a second indication of whether a coexistence condition is present. The method includes determining an antenna configuration for the multi-antenna arrangement to be used by the determined communication functionality based upon the determined communication functionality, the first indication, and the second indication. The method includes configuring the multi-antenna arrangement for the determined communication functionality based upon the antenna configuration.
