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: Some embodiments include an apparatus, method, and computer program product for using low layer protocols for inter-cell mobility management in a 5G wireless communications system. A serving 5G node B (gNB) can configure reports that a user equipment (UE) transmits to the serving gNB to make handover decisions. The serving gNB can configure a group of Transmission Configuration Indication (TCI) states (e.g., a group of beams) that correspond a physical cell, and the report includes layer 3 measurements corresponding to a neighboring or serving cell's TCI state. The report can be conveyed using lower layer protocols. The report can include layer 1 measurements conveyed using a layer 1 protocol and the serving gNB can perform filtering to generate corresponding layer 3 measurement results. Based on the reports, the serving gNB can perform a handover and synchronization using lower layer protocols, from one TCI state to another.

Abstract: An exemplary unified framework that is disclose for identifying which communication beams are to be uplink and/or downlink communication beams. This exemplary unified framework can utilize one or more universal Transmission Configuration Indication (TCI) states to identify the one or more communication beams that are to be utilized for uplink and/or downlink communication. The one or more universal TCI states can be used identify the one or more communication beams. And the one or more universal TCI states can include applicability information to identify which control channels, such as the PDCCH and the PUCCH to provide some examples, data channels, such as the PDSCH and/or the PUSCH to provide some examples, and/or signals, such as the DMRS, the PTRS, the SRS, and/or the CSI-RS to provide some examples, are to utilize the communication beams identified by the one or more universal TCI states.

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.
