Abstract: Device antennas may be allocated such that a non-LTE module (e.g., GSM module or 1x module) shares the same antenna with an LTE DRx module. This may lead to degradation of a non-LTE voice service when the LTE DRx module performs LTE transmit antenna selection causing the non-LTE module to be switched to a different antenna during reception/transmission of voice slots, resulting in a loss of slots. Accordingly, a method, an apparatus, and a computer program product for controlling antenna switching are provided. The apparatus facilitates a first radio module to use a first antenna for performing a first operation, detects that a second radio module will attempt to use the first antenna during transmit antenna selection for performing a second operation, and determines whether to switch use of the first antenna from the first radio module to the second radio module based on a type of the first operation.

Abstract: A user equipment (UE) may communicate using different radio access technologies on adjacent frequency bands. The UE may determine that the UE is not receiving wireless signals for a second radio access technology that utilizes a second frequency band adjacent to a first frequency band for a first radio access technology. The UE may place a transmitter of the UE in a filter bypass mode in which a transmit signal bypasses a transmit filter for the first radio access technology in response to determining that the wireless signals for the second radio access technology are not received. The UE may scan, using a receiver for the second radio access technology, while in the filter bypass mode, the second frequency band for a signal for the second radio access technology between scheduled transmissions for the first radio access technology.

Abstract: A wireless communication system includes: a first sub-system including a first radio and a second radio, each including a transceiver or a receiver; and a second sub-system coupled to the first sub-system and including: a first antenna configured to convey signals; a first tuner coupled to the first antenna; and a controller coupled to the first tuner, the controller being configured to cause the first tuner to adjust a characteristic of the first tuner; where the controller and/or the first tuner is configured to provide, to the first sub-system, an indication of an effect on operational performance of a portion of the second sub-system coupled to the second radio based on operation of the first tuner or the first antenna, or a combination thereof; where the first sub-system is configured to modify operation of the second radio based on the indication of the effect on operational performance.
