Abstract: Techniques discussed herein can facilitate power management at a User Equipment (UE) via selection of a power management stage based on a current power status. One example aspect is a UE comprising one or more processors configured to: monitor a temperature of the UE via one or more temperature sensors and a power usage of the UE; determine a power status of the UE based at least in part on the temperature of the UE and the power usage of the UE; select, based at least in part on the determined power status, a power management stage of a plurality of power management stages; and implement one or more power management techniques associated with the selected power management stage. A notification can be triggered to alert a user that the processor is implementing the one or more power management techniques prior to implementation.

Abstract: First user equipment (UE) exchanges at least a portion of data to be transmitted to a communication network with a second UE on a side channel. The UEs then send the data to the network at increased transmission power by using transmit antennas of both the first and second UEs, instead of just those of the first UE. In some cases, the second UE may transmit a variation of the data sent by the first UE to perform transmit diversity and improve signal-to-noise ratio. To avoid unintended beamforming of the transmissions, the network may mix signals (e.g., having a same symbol) received at the same time period but at different sub-carriers, or mix the signals received at different time periods but at the same sub-carrier. The network may notify the UEs of a phase correction value based on the signals, and the UEs may adjust using the phase correction value.

Abstract: An electronic device may include wireless circuitry with a radio that conveys wireless data with a wireless base station using antennas according to a communication schedule and that performs sensing using the antennas. The sensing may involve transmission of sensing signals and reception of reflected signals during sensing periods. Control circuitry may adjust timing of the sensing periods, based on network configuration information and the current sensing requirements of the device, to align with scheduled inactive times for the radio. In this way, the radio may perform radio-frequency sensing for use in adjusting wireless transmissions to satisfy radio-frequency exposure requirements without substantially disrupting wireless data communications.

Abstract: An electronic device may include wireless circuitry that detects the location of external objects. A signal generator may concurrently transmit different radio-frequency ranging signals over two or more transmit antennas. The ranging signals may include waveforms with time-varying frequencies, where each waveform includes frequencies that are non-overlapping with the frequencies of each of the other waveforms at any given time. Antennas may receive reflected versions of the ranging signals and a processor may process the reflected versions of the ranging signals to identify the location of the external objects. This may prevent interference between the ranging signals and may significantly reduce the latency of location detection relative to examples where the ranging signals are transmitted by different transmit antennas in series.

Abstract: A user equipment (UE), or other network component can operate to generate new radio (NR) communications in millimeter wave (mmW) frequencies. Body proximity sensing (BPS) operations can be performed to determine whether a maximum permissible exposure (MPE) event is triggered. A safe transmit power level associated with the one or more bands can then be used to provide the NR communications. Additionally, determinations of whether various conditions are satisfied to suspend the BPS operations for a period can be evaluated and implemented. The BPS can be configured such that a BPS period of the BPS operations are aligned with a discontinuous reception (DRX) cycle at a beginning of a DRX on-duration of a DRX cycle, wherein the one or more conditions comprise a DRX idle time or state.

Abstract: In a multi-radio user equipment (UE) various techniques may be used to buffer communications for a first radio access technology (RAT). A low channel quality for a second RAT is reported. An indication to halt downlink communications of the second RAT based on the reported low channel quality is received. The buffered communications by the first RAT when the second RAT downlink communications are halted are transmitted. An indication to the second RAT is sent to resume normal channel quality reporting.

Abstract: A user equipment (UE) uses information regarding the timing of scheduling mobile wireless services (MWS) RAT communications to improve MWS and wireless network connectivity (WCN) radio access technology coexistence. To allow sufficient time for an uplink grant to be received by the UE in advance of the scheduled uplink time, an uplink grant may be sent in advance of the scheduled uplink time. In some instances, the UE may receive an indication of scheduled uplink time of the MWS RAT via a physical layer communication. The UE may schedule communications of the WCN RAT based at least in part on the indication of future activity.

Abstract: In one embodiment, a wireless access point (AP) receives messages from a wireless wide area network (WWAN) device, wherein these messages identify parameters of future WWAN frames. Each message identifies a starting time, an operating band, an upload/download sub-frame configuration, and a special sub-frame pattern of a WWAN frame. The AP uses the parameters defined by each received message to determine whether to transmit a beacon frame at a scheduled target beacon transmission time (TBTT), or delay the transmission of the beacon frame to a delayed TBTT. The AP will not delay the scheduled TBTT if the parameters defined by the received message indicate there are no co-existence problems. However, the AP will delay a transmission from the scheduled TBTT if this scheduled TBTT coincides with a downlink sub-frame of the WWAN frame, and the WWAN frame has an operating band subject to interference from the intended transmission.

The processor may also monitor one or more operational parameters associated with the wireless signals, and in response thereto dynamically adjust one or both of the first and second priority values.
