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。

Abstract: Systems and methods for antenna switching without using a radio-frequency switch are provided. A signal received via a first antenna is digitized to form a first digital received signal. A signal received via a second antenna is digitized to form a second digital received signal. A switch selects the first digital received signal or the second digital received signal to be supplied to a modem to be demodulated. The switch may also supply a digital transmit signal from the modem to be supplied to digital-to-analog converters to and then transmitted using the first or second antenna. Additionally, when the modem is demodulating the signal received via the first antenna, another modem may be demodulating the signal received via the second antenna and vice versa.

Abstract: Apparatus, methods, and computer-readable media for facilitating UE beam selection based on service demands are disclosed herein. An example method of wireless communication includes determining to select an UL beam having a higher EIRP capability than an EIRP capability associated with a current beam for transmitting on UL when at least one of a target transmit power based on a TPC exceeds an EIRP capability associated with the current beam or when an amount of data in a buffer of the UE is greater than a data threshold. The example method also includes determining, upon determining to select the UL beam, a set of UL beams with an EIRP capability satisfying an EIRP capability threshold and a respective beamforming direction corresponding to a beamforming direction associated with the current beam, selecting one UL beam of the set of UL beams, and transmitting on UL on the selected UL beam.

Abstract: Aspects of the present disclosure provide techniques for the user equipment (UE) to select a power management mode from a plurality of power management modes supported by the UE based on decoding of a portion of the downlink subframe. For example, when the UE receives a subframe from a base station, the UE may decode a control channel region of the subframe to determine whether the subframe includes a channel grant allocated to the UE. If no channel grant is included in the subframe, the UE may select a power management mode for the UE from the plurality of power management modes supported by the UE that maximizes the UE's sleep opportunities while balancing the deficient performance costs.

Abstract: Techniques for providing transmission throttling for emission exposure management are described. Embodiments implement duty cycle based transmission throttling for emission exposure management. Transmission throttling implemented in accordance with embodiments drops or skips transmission of some portion of transmission blocks of a communication process, such as to drop some transmission blocks providing retransmission of data. Transmit power levels utilized with respect to each of transmission blocks transmitted may be closer to that of a transmit power control target level (e.g., meeting the TPC target level) while nevertheless meeting an emission exposure limit level. Embodiments may, for example, be implemented with respect to a hybrid automatic repeat request (HARQ) process. Other aspects and features are also claimed and described.
