Abstract: Aspects of the present disclosure relate to wireless communication. In some aspects, a user equipment (UE) may receive a downlink grant that does not include a downlink assignment index (DAI); determine a pre-defined bundle window, associated with ACK/NACK multiplexing or bundling, based at least in part on receiving the downlink grant that does not include the DAI; and transmit ACK/NACK feedback to acknowledge or negatively acknowledge one or more downlink communications received in the pre-defined bundle window. In some aspects, a UE may receive a downlink grant that does not include a DAI; determine a bundle window, associated with ACK/NACK multiplexing or bundling, based at least in part on receiving the downlink grant that does not include the DAI, wherein the bundle window is not pre-defined; and transmit ACK/NACK feedback to acknowledge or negatively acknowledge one or more downlink communications received in the bundle window. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide a bandwidth-dependent maximum number of control symbols. As described herein, a BS may determine a channel bandwidth for communicating with a UE, determine a maximum number of downlink control symbols based, at least in part, on the determined channel bandwidth, and transmit up to the maximum number of downlink control symbols to the UE. According to aspects, a DMRS may be transmitted after the maximum number of downlink control symbols. For example, the DMRS may be transmitted in a symbol immediately following the downlink control symbols.

Abstract: Aspects herein describe increasing density of reference signal transmissions in wireless communications. A plurality of reference signal configurations, each indicating resource elements for one or more antenna ports over which reference signals for the one or more antenna ports are scheduled for transmission, can be received. An association configuration indicating an association between at least two antenna ports as having similar channel characteristics can also be received. A plurality of reference signals can be received in the resource elements corresponding to the at least two antenna ports as indicated in the at least two of the plurality of reference signal configurations, which can be used to perform a channel measurement of the similar channel characteristics of channels of the at least two antenna ports over at least a portion of the plurality of reference signals.

Abstract: The present disclosure relates to efficient transmission of acknowledgment (ACK) and negative ACK (NACK) information in a wireless communication system. For example, a user equipment (UE) may transmit, on an uplink communication channel, one or more data packets to a network entity. The UE may further receive, on a downlink communication channel, a clustered ACK/NACK indication from the network entity in response to transmitting the one or more data packets on the uplink communication channel. Additionally, for instance, a network entity may receive, on an uplink communication channel, one or more data packets from a user equipment. The network entity may also transmit, on a downlink communication channel, a clustered ACK/NACK indication from the network entity in response to receiving the one or more data packets on the uplink communication channel.

Abstract: In order to provide a more robust RLM procedure for 5G/NR, a base station may provide a dynamic relationship between a PDCCH and another reference signal (e.g., SS/CSI-RS) to a UE. For example, an apparatus may receive an adjustment parameter regarding a PDCCH from a base station. The adjustment parameter may comprise a relationship between the PDCCH and the at least one of the SS or the CSI-RS for deriving a radio link quality of a hypothetical PDCCH. The apparatus may receive an SS/CSI-RS that is QCL with the PDCCH and perform a radio link measurement based on the received at least one of the SS or the CSI-RS using the adjustment parameter regarding the PDCCH. Among other relationships/offsets, the adjustment parameter may indicate a TPR difference, a beamforming gain difference, a beam width difference, a beam orientation difference.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive when operating in a network that provides synchronization signals at a plurality of locations in a channel bandwidth, a common search space (CSS) indicator for a synchronization signal, wherein the CSS indicator indicates that the synchronization signal is not associated with a CSS for a downlink control channel. The user equipment may determine a location of the CSS for the downlink control channel based at least in part on the CSS indicator. Numerous other aspects are provided.

Abstract: The present disclosure describes various aspects of the implementation and design of Physical Downlink Control Channel (PDCCH) in 5G new radio (NR) applications. Aspects include methods, apparatuses, and computer-readable medium for one or more of multiple PDCCH search spaces, control resource block (CRB), irregular multiple slots or mini-slots grants, or fast control channel signaling for grant-free uplink (UL). For example, different scheduling entities can each have one or two search spaces defined (e.g., common and/or user equipment (UE)-centric search spaces). Also, CRBs can be used as units for PDCCH transmission instead of resource element groups/control channel elements (REGs/CCEs). In addition, irregularities in time domain, frequency domain, or both can be introduced in the granting of resource blocks (RBs) over multiple slots or mini-slots. Moreover, signaling can be used to indicate to a UE configured for grant-free UL the portion of the pool of resources available for grant-free UL.

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.
