Abstract: RESUMEN Un equipo de usuario (UE) puede recibir, desde una estación base, un bloque de señal de sincronización (SSB) de un conjunto de SSB cuasicoubicados (QCL), comprendiendo el SSB una indicación de un parámetro que indica información asociada con una pluralidad de ubicaciones de canal de control de enlace descendente correspondientes al conjunto de SSB QCL. El UE puede determinar, basándose al menos en parte en el parámetro, la pluralidad de ubicaciones de canal de control de enlace descendente correspondientes al conjunto de SSB QCL. El UE puede recibir una concesión de enlace descendente para una información del sistema basada al menos en parte en la monitorización de una o más ubicaciones de canal de control de enlace descendente de la pluralidad de ubicaciones de canal de control de enlace descendente. El UE puede recibir la información del sistema basándose, al menos en parte, en la concesión del enlace descendente. El UE puede establecer una conexión con la estación base basada al menos en parte en la SSB y la información del sistema recibida.

Abstract: A user equipment (UE) may receiving, from a base station, a synchronization signal block (SSB) of a set of quasi-collocated (QCL) SSBs, the SSB comprising an indication of a parameter indicating information associated with a plurality of downlink control channel locations corresponding to the set of QCL SSBs. The UE may determine, based at least in part on the parameter, the plurality of downlink control channel locations corresponding to the set of QCL SSBs. The UE may receive a downlink grant for a system information based at least in part on monitoring one or more downlink control channel locations of the plurality of downlink control channel locations. The UE may receive the system information based at least in part on the downlink grant. The UE may establish a connection with the base station based at least in part on the SSB and the received system information.

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: Methods, systems, and devices for using a common physical downlink control channel (PDCCH) to indicate transmission beams to be used by a base station during a transmission opportunity or a periodicity to monitor search spaces are described. A user equipment (UE) may monitor a search space (in some cases, using a periodicity) for the common PDCCH to determine if transmission beams associated with the UE are to be used during the transmission opportunity. If so, the UE may wake-up during at least a portion of the transmission opportunity to receive additional information. If the common PDCCH indicates that no transmission beams associated with the UE are to be used during the transmission opportunity, the UE may enter or re-enter the sleep state. The UE may switch to a new periodicity for monitoring the search space based on the information transmitted within the common PDCCH.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive downlink control information within a control resource set (CORESET) configured with a wideband demodulation reference signal (DMRS) and including disjoint segments of resource blocks (RBs). The downlink control information may be located at least partially within a first segment of the disjoint segments and a second segment of the disjoint segments may be exclusive of the downlink control information. The downlink control information may include a grant of a set of resources for a downlink shared channel that overlaps with the CORESET. The UE may determine a rate matching operation for the wideband DMRS for a downlink shared channel for portions of the set of resources that overlap with the second segment of the disjoint segments, and receive the downlink shared channel on the set of resources according to the determined rate matching operation.

Abstract: Wireless communications systems and methods related to communicating in a frequency band based on bandwidth parts are provided. A first wireless communication device communicates with a second wireless communication device, a first configuration indicating a plurality of bandwidth parts in a frequency band, the plurality of bandwidth parts based on an expected channel access pattern associated with a listen-before-talk (LBT) in the frequency band. The first wireless communication device communicates, with the second wireless communication device, a first communication signal in a first bandwidth part of the plurality of bandwidth parts based on an LBT result.

Abstract: Timing considerations for autonomous uplink (AUL) downlink feedback information (AUL-DFI) is disclosed. With the flexible timeline for new radio (NR) operations, signaling of the processing timeline may be used for the served user equipments (UEs) to properly interpret the acknowledgement information in the AUL-DFI. The UE receives a signal identifying a minimum processing time of the serving base station to process AUL. Using the knowledge of the minimum processing time, the UE determines which of the outstanding AUL transmissions are accurately addressed in the AUL-DFI and which are still pending. Additional signaling to the UE may instruct the UE when to implement any changes to transmission parameters also signaled via the AUL-DFI. Slots prior to the indicated change time will be transmitted using the current parameters, while slots after the indicated time will use the updated parameters from the AUL-DFI.
