Abstract: Beam determination refers to a set of procedures for an access node (AN) and a user equipment (UE) to select from among downlink communication beams and/or uplink communication beams for downlink and/or uplink communications, respectively. Often times, the downlink communication beams can include one or more downlink control channels, for example, a Physical Downlink Control Channel (PDCCH) and/or a Physical Downlink Shared Channel (PDSCH), to provide downlink reference signals, such as channel-state information reference signals (CSI-RSs), to the UE. The AN can execute various exemplary downlink beam scheduling procedures to control the transmission of the downlink reference signals, such as the CSI-RSs to provide an example, over the downlink communication beams. In some embodiments, the UE can utilize the CSI-RSs to perform beamforming failure detection (BFD) and beamforming failure recovery (BFR) in the wireless networks.

Abstract: A user equipment (UE) reports capabilities to a network. The UE receives a request from a network for radio access capabilities of the UE, determines one or more radio access capabilities related to a supported number of component carriers (CCs) for physical downlink control channel (PDCCH) monitoring by the UE, generates the message that includes the one or more radio access capabilities of the UE and transmits the message to the network.

Abstract: Some aspects of this disclosure include apparatuses and methods for implementing mechanisms for downlink control information between an electronic device (for example, a UE) and a network for cell detection and measurement. For example, some aspects relate to an electronic device including a transceiver and a processor communicatively coupled to the transceiver. The processor monitors one or more paging occasions within a discontinuous repetition cycle (DRX) and can make a determination of one or more paging occasions within the DRX to not monitor. Each paging occasion may include a transmission by the network of downlink control information for one or more paging messages.

Abstract: An approach for wireless communications to support reduced capability New Radio (NR) with larger available control resource sets (CORESET) bandwidths. Examples include a frequency-hopping CORESET with a predefined hopping pattern configured by higher layers, such as RRC signaling or MAC Control Element (CE) on a per CORESET per UE or purely per UE basis. Frequency hopping patterns for CORESET transmissions include the use of PRBs for CORESETs that are mirrored with respect to the central frequency of active bandwidth part (BWP), and the use of a random parameter to step through the frequency pattern. The sub-band location of the physical downlink shared channel that is scheduled by the physical downlink control channel may be indicated using the DCI format, or may be based on a last slot for PDCCH transmission.

Abstract: Devices, systems and methods for implementing beam failure management techniques at a user equipment (UE). The UE receives a timing advance command (TAC) from a currently camped cell and initiates a time advance timer (TAT). When the TAT is running the UE is in a first operating state. The first operating state indicates that the UE is in time alignment with the cell. The UE identifies that the TAT has expired. When the TAT is not running the UE is in a second operating state. The second operating state indicates that the UE is not in time alignment with the cell. The UE implements one or more beam failure management techniques based on the UE operating in the second operating state.

Abstract: A user equipment (UE) receives reference signals during a discontinuous reception (DRX) cycle to perform frequency and timing tracking or automatic gain control (AGC). The UE receives configuration information corresponding to a reference signal that is to be transmitted to a user equipment (UE) when the UE is in a first operating state, receives the reference signal from a cell of a network when the UE is in the first operating state, performs one of frequency and timing tracking or automatic gain control (AGC) using the reference signal and receives a signal from the cell during a time window that the UE is scheduled to utilize an active mode of data exchange processing.

Abstract: Systems and methods for using clear channel assessment (CCA) on a channel prior to transmitting the channel are disclosed. A wireless transmission system may perform omnidirectional CCA using a CCA power threshold that is calculated based on a number of synchronization signal blocks (SSBs) transmitted by the wireless transmission system per SSB burst or per synchronization signal/physical broadcast channel (SS/PBCH) block measurement timing configuration (SMTC) window, or on a number of transmit (Tx) antennas used. A wireless transmission system may perform directional CCA on one or more Rx beams that correspond to one or more intended Tx beams using CCA power thresholds calculated based on an equivalent isotropic radiated power (EIRP) of the one or more intended Tx beams to determine directional availability of the channel. A wireless transmission system may determine a CCA power threshold based on a scaling between an actual CCA bandwidth and a nominal CCA bandwidth.
