TX antenna selection for LTE in multiple radio devices
First Claim
1. A method of controlling antenna switching, comprising:
- facilitating a first radio module to use a first antenna for performing a first operation;
detecting that a second radio module will attempt to use the first antenna for a periodic transmission of a reference signal as a part of transmit antenna selection for performing a second operation while the first radio module is using the first antenna for performing the first operation; and
determining whether to refrain from switching use of the first antenna from the first radio module to the second radio module based on a type of the first operation,wherein refraining from switching includes throttling an ability of the second radio module to perform the transmit antenna selection by lowering a frequency at which the second radio module performs the transmit antenna selection.

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.
