Abstract: Certain aspects of the present disclosure provide techniques that may be used to help enable low latency communications between a user equipment (UE) and a base station (BS) using quick uplink channels that enable a reduced transmission time interval (TTI). Additionally, certain aspects of the present disclosure provide techniques for managing communications in a wireless communication system, for example, by using enhanced downlink control channels.

Abstract: The present disclosure describes various examples of a method, an apparatus, and a computer readable medium for multi-state discontinuous reception (DRX) in wireless communications. For example, one of the methods described may include identifying, by a user equipment (UE), at least two states in connected mode, determining, by the UE, one or more triggers for transitioning between the at least two states, and transitioning, by the UE, from a first state of the at least two states to a second state of the at least two states in response to a determination of the one or more triggers. In an aspect, the transitioning comprises transitioning between cross-slot scheduling and same-slot scheduling, or between a narrow bandwidth and a wide bandwidth, or between a larger periodicity and a smaller periodicity for monitoring.

Abstract: A method for communication includes a user equipment (UE) periodically awakening to monitor for a wake-up signal (WUS) in a wake-up signal search space, the wake-up signal having a shorter length than a length of a control channel communication to allow the UE to determine whether the UE should monitor for the control channel communication.

Abstract: Various aspects described herein relate to techniques for mobility mode selection in uplink-based and downlink-based mobility in wireless communications systems. In an aspect, a method for wireless communications may include determining that a user equipment (UE) is operating in a first mobility mode, determining whether the UE satisfies at least one condition associated with mobility of the UE for mobility mode selection, and selecting a second mobility mode based on a determination that the UE satisfies the at least one condition, wherein each of the first mobility mode and the second mobility mode is an uplink mobility mode or a downlink mobility mode. The techniques described herein may apply to different communications technologies, including the 5th Generation (5G) New Radio (NR) communications technology.

Abstract: Certain aspects of the present disclosure provide techniques for a slot format indicator (SFI) and slot aggregation level indication in a group common physical downlink control channel (GC PDCCH) and conflict handling for the SFI. According to certain aspects, a method of wireless communication by a base station (BS) is provided. The BS can determine a slot aggregation level and a format of the aggregated slots and send a downlink control channel including a SFI indicating the format of the aggregated slot and an indication of the slot aggregation level. The UE can receive the downlink control channel including the SFI and the indication of the slot aggregation level and the UE can determine a format of a current slot based on the received SFI and slot aggregation level.

Abstract: A method and apparatus for enabling an UE to selecting acknowledgement/non-acknowledgement (ACK/NACK) resources from a subset of a gNB resource pool. The example method may receive, from an gNB, a radio resource control (RRC) configuration indicating a UE-specific resource set that is a subset of a gNB resource pool. The UE may determine one or more ACK/NACK resources from the UE-specific resource set for an upcoming physical uplink control channel (PUCCH). In some aspects, the UE may determine the one or more ACK/NACK resources based on receiving, from the gNB, a physical downlink control channel (PDCCH) including a corresponding ACK/NACK resource configuration. In other aspects, the RRC may contain multiple resource subsets and the UE may determine the one or more ACK/NACK resources based on determining a size of a payload for a UCI to be transmitted on the PUCCH. The aspects may thus enable dynamic ACK/NACK resource allocation.

Abstract: Aspects of the present disclosure describe determining an uplink channel raster for determining frequency location of an uplink channel over which to transmit uplink communications to a base station. Uplink communications can be transmitted to the base station over the uplink channel. The uplink channel raster can be shifted, in frequency, with respect to a legacy uplink channel raster of a legacy communication technology to facilitate coexistence, in an uplink carrier, of the uplink channel and one or more uplink channels of the legacy communication technology.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for implementing one or more ECCE index determinations for MPDCCH in special subframes in eMTC using communications systems operating according to new radio (NR) technologies. For example, a method for wireless communications may include determining a type of channel is scheduled to be transmitted across multiple subframes, determining a first subframe of the multiple subframes is of a first subframe type that is different than a second subframe type of one or more other subframes of the multiple subframes, and determining resources for a decoding candidate of a channel based, at least in part, on the first subframe type and the second subframe type.

Abstract: Aspects of the present disclosure provide techniques and apparatus for performing narrowband physical random access channel (PRACH) procedures in large cells. For example, aspects of the present disclosure provide techniques for narrowband PRACH procedures (e.g., narrowband internet of things (NB-IoT)) to accommodate larger RTTs (e.g., up to 100 km). In some cases, supporting larger RTTs may involve a base station altering its PRACH processing by performing a two-step process of, first, obtaining a frequency domain phase offset based on an uplink signal from a UE, which provides a fractional delay and, second, performing a time domain correlation for different timing hypotheses to determine a timing offset based on the uplink signal. Supporting larger RTTs may also involve enabling a new NPRACH format that may coexist with legacy 3.75 kHz resources.
