Abstract: Methods, systems, and devices for wireless communications at a user equipment (UE) are described. Techniques are described herein for performing out-of-order processing. The UE may receive a first downlink channel at a first time and a second downlink channel at a second time. The UE may determine that a priority of the second downlink channel is different (e.g., higher) than a priority of the first downlink channel. The UE may determine that a first uplink transmission associated with the first downlink channel is to be transmitted after a second uplink transmission associated with the second channel based on the different priorities. The UE may set one or more operations based on these determinations. In some cases, the UE may suspend processing the of the first downlink channel to process the second downlink channel.

Abstract: Wireless communications systems and methods related to improve control reporting latency are provided. A wireless communication device receives, from a first link in a first time interval, first control information associated with a second link and the first time interval. The wireless communication device transmits, via the second link in the first time interval, a control report associated with the second link based on a report configuration that is independent from the first control information. The report configuration is associated with a waveform type. The wireless communication device receives, from the first link in a second time interval following the first time interval, second control information that is dependent on the control report. The report configuration includes a power headroom (PHR) report configuration. The PHR report configuration includes a reference PHR report configuration. The PHR report configuration includes a delayed PHR report configuration.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive a first set of grants for performing uplink transmissions between the UE and a first group of cells associated with a first radio access technology (RAT) and a second set of grants for performing uplink communication between the UE and a second group of cells associated with a second RAT. The UE may determine that a combined transmit power exceeds a total power limit or that there may be a potential of the combined power exceeding the total power limit. The UE may further perform the uplink communication with the first group of cells using the first RAT and the second group of cells using the second RAT.

Abstract: Methods, systems, and devices for wireless communications are described that support configuration of aperiodic sounding reference signal transmission and triggering. A base station may transmit, within a first transmission time interval (TTI), a grant triggering a user equipment (UE) to transmit an aperiodic sounding reference signal (A-SRS), and may identify offset information indicating a TTI offset relative to the grant. The base station may determine a second TTI for the A-SRS based on the TTI offset. A UE may detect, within a first TTI, the grant triggering the UE to transmit the A-SRS, identify the offset information indicating the TTI offset relative to the grant, and determine the second TTI for transmitting the A-SRS based on the TTI offset. The UE may transmit the A-SRS in an SRS resource of the second TTI, and the base station may monitor the SRS resource of the second TTI for the A-SRS.

Abstract: A wireless device may identify a set of resources reserved for feedback information (e.g., resource elements (REs) reserved for feedback such as acknowledgement (ACK) or negative ACK (NACK) information) within a transmission time interval (TTI). Feedback information may be mapped to the reserved set of resources (e.g., reserved REs). The wireless device may determine a set of unused reserved resources (e.g., a set of unused reserved REs) based on the number of feedback bits. The wireless device may then map other bits (e.g., zeros, known bits, pattern or sequence of bits, random bits, etc.) to the set of unused reserved REs, or boost transmission power of bits mapped around the unused reserved REs. In some cases, the number of reserved REs may be determined based on the number of feedback bits (e.g., the size of the ACK/NACK payload). The wireless device may then transmit the information to a base station.

Abstract: A configurable new radio (NR) RACH procedure that may be executed by a UE and a base station is disclosed. A first message can be transmitted, in an inactive or idle state, a on a physical random access channel, where the first message includes a random access preamble. A second message can be received on a downlink channel in response to the first message, where the second message includes a temporary cell radio network temporary identifier and an uplink grant for the user equipment. A request can be transmitted on an uplink channel based on the uplink grant. A common search space of a downlink control channel can be monitored, such as for an acknowledgement message or a negative acknowledgement message corresponding to the request and identifiable based on the temporary cell radio network temporary identifier.

Abstract: Aspects of the present disclosure provide apparatus and techniques that may be applied in systems that may help enable efficient communication between a base station (BS) and certain devices, such as wearable devices and/or machine type communication (MTC) user equipments (UEs), having a single receiver (RX) for long term evolution (LTE). An exemplary method, performed by a BS, generally includes receiving, from a UE, an indication of a category of the UE, wherein the category of the UE indicates at least one of: a maximum throughput supported by the UE or a number of layers supported by the UE; assuming a number of receivers at the UE based on the category of the UE; determining one or more transmit parameters based on the number of receivers of the UE; and communicating with the UE according to the one or more transmit parameters.

Abstract: Methods, systems, and devices for radio resource management (RRM) measurement and reporting for license assisted access (LAA) cells operating in unlicensed or shared frequency spectrum are described. A user equipment (UE) may receive an RRM measurement configuration including a channel occupancy parameter for measuring neighbor cells of a shared frequency band. The channel occupancy parameter may be used to determine a channel occupancy metric that may be sent to a base station for cell selection. The channel occupancy metric may include an averaged or filtered received signal strength and may be reported for serving cells and/or intra-frequency neighbor cells. A base station may further configure a UE with a discovery reference signals (DRS) measurement timing configuration (DMTC), which may include an extended DMTC search window. The UE may search for DRS transmissions from neighbor cells according to the DMTC.

Abstract: Systems and method of embodiments herein operate to conserve battery power of user equipment (UE). Embodiments determine whether waking up a UE receiver would be beneficial and based on the determination, the UE either wakes up the receiver or returns to sleep. Embodiments determine whether to wake up the receiver by performing pre-wake up (PWU) operation which either wakes up the receiver in a low power mode or wakes up the UE's wake up receiver. It may be determined whether a wake up (WU) signal is received during a PWU stage. If a WU signal is received during the PWU stage the UE may perform a full wake up of the receiver. If a WU signal is not received the UE may return to idle mode. In embodiments, WU (Wake Up) DRX cycles are supplemented with a Full DRX (Discontinuous Reception) cycle.
