    Abstract: A UE may determine a number of resources granted for uplink or downlink communication in a processing window. The resources may include uplink resources or downlink resources and the processing windows may include a predetermined number of subframes. For uplink (UL) transmissions, this may include determining a number of transport block bits, resource blocks, or other resources scheduled in one or more first UL channel grants for a first UL channel, and determining a number of such resources scheduled in a second UL grant for a second UL channel. For downlink (DL) transmissions, the determining may include determining a number of resources received on a first DL channel in each subframe of a set of subframes, and determining a number of resources received on a second DL channel. The determined number of UL or DL resources may be compared to a corresponding threshold which his based on the UE capabilities and processed in accordance a result of the comparison. These and additional aspects are described herein.

    Abstract: An apparatus is disclosed for radar interference mitigation using a pseudorandom offset. The apparatus includes an antenna array and a wireless transceiver. The wireless transceiver is coupled to the antenna array and is configured to transmit, via the antenna array, a radar transmit signal based on at least one pseudorandom offset. The wireless transceiver is also configured to receive, via the antenna array, at least a portion of another radar transmit signal from another apparatus. The wireless transceiver is additionally configured to receive, via the antenna array, a radar receive signal that includes a portion of the radar transmit signal that is reflected by an object. At a given time, a frequency of the radar receive signal is different than a frequency of the radar transmit signal based on the at least one pseudorandom offset.

    Abstract: Certain aspects of the present disclosure generally relate to randomization of positioning reference signal (PRS) frequency offsets and muting patterns in long term evolution (LTE) for enhanced observed time difference of arrival (eOTDOA). According to certain aspects, a method is provided for wireless communications which may be performed, for example, by a base station (BS). The method generally includes randomly selecting at least one parameter used to determine a set of time-frequency resources for transmitting positioning reference signals (PRS) and transmitting PRS on the determined set of time-frequency resources. The user equipment (UE) may randomly select the at least one parameter used to determine the set of time-frequency resources to measure for the PRS from the BS and measure PRS on the determined set of time-frequency resources.

    Abstract: Certain aspects of the present disclosure generally relate to wireless communications, and more specifically to reference signal design for communications with coverage enhancements and devices with limited communications resources, such as machine type communication (MTC) devices, enhanced or evolved MTC (eMTC) devices, and internet of things (IoT) devices. An example method generally includes determining a set of additional reference signals to transmit in a bundled transmission, based on a bundle length of the bundled transmission, and transmitting the bundled transmission, reference signals, and the additional reference signals, based on the determination.

    Abstract: A user equipment (UE) may communicate over a first wireless wide area network (WWAN). The first WWAN may be supported by a first subscriber identity module (SIM) of the UE. The UE may also communicate simultaneously over a second WWAN supported by a second SIM. The UE may process the second WWAN communication with a portion of a WWAN module and a portion of a wireless local area network (WLAN) module.

    Abstract: Timing resolution for user equipments (UEs) that operate using a discontinuous reception (DRX) mode that includes various sleep cycles may be addressed through selection of various alternative wake up procedures. A UE selects a wake-up procedure based on the length of the sleep cycle. The UE may use details of the sleep cycle, including a time offset or timing uncertainty associated with the sleep cycle, when selecting the wake-up procedure. The UE may select to obtain system timing information either directly from a serving cell or non-serving cell in sync with the serving cell or may select to perform either a one-step or two-step pre-wake up procedure in order to obtain the system timing. Once the UE obtains the system timing or determines a wake-up procedure, it performs timing correction before the scheduled wake-up times between the sleep cycles.
