Abstract: A method and apparatus configuring default beams are described. In some embodiments, the method of wireless communication at a User Equipment (UE) comprises: receiving, from a base station, configuration information for configuring a default beam for the physical downlink shared channel (PDSCH) to use on condition that an offset between reception of downlink control information (DCI) in the scheduling physical downlink control channel (PDCCH) and corresponding PDSCH is less than a threshold and at least one Transmission Configuration Indicator (ICI) states includes spatial receiving parameters for configuring a quasi-co-location; configuring, by the UE, a default beam configuration for the PDSCH based on the configuration information and a monitored control resource set (CORESET) with a lowest CORESET identifier (ID) from among a set of CORESETs in a latest slot in a same bandwidth part (BWP), wherein at least one CORSET of the set of CORESETs includes more than one TCI state; and receiving a transmission using the default beam.

Abstract: Systems, methods, and apparatuses for muting resource elements used for wireless communications is disclosed. In one aspect, a method can include actions of obtaining, by user equipment (UE), configuration data that indicates a frequency density of muted resource blocks, identifying, by the UE and based on a value of an antenna ports information element in downlink control information (DCI) that schedules a PUSCH transmission, a group of resource elements within the muted resource blocks, determining, by the UE, a muted resource pattern (MRP) within the RBs for the scheduled PUSCH based on the frequency density of the muted resource blocks and the identified group of resource elements, and transmitting, by the UE, an allocation of RBs for PUSCH without transmission on the identified group of resource elements of the determined MRP.

Abstract: A wireless user equipment (UE) may employ any of various mechanisms for reporting signal quality measurements to a wireless network. The UE may impose a time delay between measurement and reporting, based on a delay parameter K. The UE may average measurements obtained at different measurement instances. The UE may employ any of various schemes for prioritizing transmission of one type of report over another, when temporal collisions occur between different types of report. The UE may employ a differential report that includes a state for indicating that a beam is not workable. The UE may employ a beam index that includes a state for indicating an invalid beam. A base station may receive a signal quality report and determine workability of a beam, e.g., by triggering a report of channel state information.

Abstract: A smart repeater (SMR) can be configured to amplify and forward data from a base station based on received control information for managing power efficiency of on-off operations. The SMR can configure a power control mechanism based on the control information to adapt one or more bandwidths associated with the SMR based on the control information to save power and forward the communications to the base station or the UE. The control information can include a component carrier (CC) index or a bandwidth part (BWP) identifier (ID), and a set of parameters to configure on-off operations of the one or more bandwidths according to one or more CCs or BWPs.

Abstract: Apparatuses, systems, and methods for performing downlink signal reception with antenna panel switching in a wireless communication system. A cellular base station may receive an indication of an antenna panel activation delay from a wireless device. The cellular base station may select a scheduling offset for a transmission to the wireless device based at least in part on the antenna panel activation delay. The scheduling offset may be selected to be at least the length of the antenna panel activation delay if it is expected that the wireless device may perform antenna panel activation to receive the transmission. The cellular base station may schedule the transmission to the wireless device using the selected scheduling offset, and may perform the transmission to the wireless device at the selected scheduling offset after scheduling the transmission to the wireless device.

Abstract: Inter-cell mobility may include decoding a first radio resource control (RRC) reconfiguration message received from a first cell. The first RRC reconfiguration message may comprise a first portion of configuration information for performing a cell change to a second cell. A cell change message received from the first cell may be decoded. The cell change message may indicate that a cell change to the second cell is to be performed. A cell change acknowledgment may be encoded for transmission to the second cell. A second RRC reconfiguration message received from the second cell may be decoded. The second RRC reconfiguration message may comprise a second portion of configuration information for performing the cell change to the second cell. The second portion of configuration information may comprise a remaining portion of configuration information to perform the cell change to the second cell.
