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: An antenna system includes: a radiating element; a feed coupled to the radiating element at a first point on the radiating element and configured to convey energy to the radiating element; and a radiation-adjustment device coupled to the radiating element at a second point, configured to alter a radiation characteristic of the radiating element, and including: coarse-adjustment elements; an integrated-circuit chip including: switches, each coupled to a respective one of the coarse-adjustment elements where the coarse-adjustment elements are disposed external to the integrated-circuit chip; and a fine-adjustment circuit; the antenna system further including a controller communicatively coupled to the switches and to the fine-adjustment circuit, the controller configured to alter the radiation characteristic of the radiating element by selectively causing one or more of the switches to couple one or more of the coarse-adjustment elements to the radiating element, and by adjusting a value of the fine-adjustment circuit.

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.

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 translation: 可以分配设备天线，使得非LTE模块（例如，GSM模块或1x模块）与LTE DRx模块共享相同的天线。 当LTE DRx模块执行LTE发射天线选择时，可能导致非LTE语音业务的劣化，导致在接收/发送语音时隙期间将非LTE模块切换到不同的天线，导致时隙损失。 因此，提供了一种用于控制天线切换的方法，装置和计算机程序产品。 该装置有助于第一无线电模块使用第一天线来执行第一操作，在发射天线选择期间检测第二无线电模块将尝试使用第一天线来执行第二操作，并且确定是否切换使用第一无线电模块 基于第一操作的类型从第一无线电模块到第二无线电模块的天线。
