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: Some aspects of this disclosure relate to apparatuses and methods for implementing designs for configurations of resource elements to carry reference signals for a user equipment (UE). A reference signal can be processed by the UE according to the configuration of resource elements to carry reference signals. The configurations can be determined by the base station, and received from the base station by the UE. The base station determines the configurations based on information or parameters provided by the UE, e.g., a coherence bandwidth of the channel, a coherence time of the channel, a preference associated with channel status information reference signal, or a preference associated with demodulation reference signal for the UE.

Abstract: Embodiments include a user equipment (UE) and methods performed by the UE. The methods include receiving a measurement configuration request from a network, in response to the measurement configuration request, measuring a quality of one or more uplink (UL) carrier aggregation (CA) combinations, wherein each UL CA combination comprises a plurality of component carriers, generating a message that includes the quality of the one or more UL CA combinations and transmitting the message to the network. Further embodiments include the above operations being performed as a set of instructions executed by a processor or an integrated circuit that includes circuitry to perform the operations.

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.
