Abstract: Systems and methods of increasing paging opportunities when the unlicensed band is used are described. The gNB sends an RRC message that indicates multiple monitoring occasions in a paging occasion of a paging frame. The UE monitors a monitoring occasion of a PO to determine whether a PDCCH with a P-RNTI has been received in an unlicensed band. If such a PDCCH is received, the UE decodes PDSCH information in the PDCCH to determine whether the P-RNTI is a P-RNTI of the UE. If so, the UE avoids monitoring subsequent monitoring occasions of the PO. If the PDCCH does not contain a P-RNTI, the UE continues to monitor other monitoring occasions within the PO.

Abstract: An apparatus of user equipment (UE) includes processing circuitry coupled to memory, where to configure the UE for communication of data in a New Radio-Unlicensed (NR-U) spectrum, the processing circuitry is to decode RRC signaling from a base station. The RRC signaling includes configuration information to configure a listen-before-talk (LBT) timer and a scheduling request (SR) prohibit timer. An LBT procedure is performed while the LBT timer is activated. An SR is encoded for transmission to the base station, based on detecting an unoccupied transmission resource within the NR-U spectrum during the LBT procedure. The SR transmission activates the SR prohibit timer. An uplink grant from the base station is decoded in response to the SR, the uplink grant received while the SR prohibit timer is activated. A buffer status report (BSR) is encoded for transmission to the base station based on the uplink grant.

Abstract: The disclosure is directed to a system and method of operating a user equipment (UE) to make the new radio (NR) carrier aggregation more effective. The system and method can include at least: receiving a release message confirming release of the UE from a base station, the release message including Long Term Evolution radio access technology (RAT) frequencies and New Radio (NR) RAT frequencies; measuring during an IDLE state, the LTE RAT frequencies and the NR RAT frequencies; transmitting a resume request message to the base station, the resume request message including an indication of a measurement report available from the UE, the measurement report including frequency measurements for the LTE RAT frequencies and the NR RAT frequencies; and after a security setup with the base station, transmitting a resume complete message to the base station, the resume complete message including the measurement report with the LTE RAT frequency measurements and NR RAT frequency measurements.

Abstract: Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The UE may receive, from a gNB, configuration information related to a 2-step random access (RA) procedure between the UE and the gNB in unlicensed spectrum. The 2-step RA procedure may include: an uplink MsgA message that includes, within a random access occasion (RO), a MsgA preamble and a MsgA payload; and a downlink MsgB message that includes, within another RO, a MsgB PDCCH and a MsgB payload. The configuration information may indicate: resources allocated for the MsgA preamble; and a mapping between the resources allocated for the MsgA preamble and the MsgA payload. The UE may determine the resources allocated for the MsgA payload based on the resources allocated for the MsgA preamble and the mapping.

Abstract: Embodiments of an Evolved Node-B (eNB), User Equipment (UE) and methods for communication are generally described herein. The eNB may receive, from a UE, uplink control information (UCI) that indicates a hybrid automatic repeat request identifier (HARQ ID) for a grant-less uplink (GUL) transmission by the UE during a first sub-frame. The eNB may select, from candidate HARQ IDs, a HARQ ID for a scheduled uplink (SUL) transmission by another UE in a second sub-frame after the first sub-frame. The eNB may, if the GUL transmission is successfully decoded, include the HARQ ID for the GUL transmission in the candidate HARQ IDs for the GUL transmission. The eNB may, if the GUL transmission is not successfully decoded, exclude the HARQ ID for the GUL transmission from the candidate HARQ IDs for the GUL transmission.

Abstract: Systems, apparatuses, methods, and computer-readable media are provided for a user equipment (UE) device that includes one or more processors configured to determine, based on a DL signal in an LTE-TDD radio frame, that an eNB has assessed, based on a Cat-2 listen before talk (LBT) procedure, that a radio frame is valid; and in response to determining that the radio frame is valid, transmitting a UL burst within a predetermined period of time after a DL burst in the radio frame.

Abstract: A network device (e.g., a user equipment (UE), or a new radio NB (gNB)) can process or generate a configuration of a physical random access channel (PRACH) over physical resource blocks (PRBs) that are interlaced in an unlicensed band in an NR unlicensed (NR-U) communication. The PRBs in the PRACH can be based on an occupied channel bandwidth (OCB) of the unlicensed band in the NR-U communication. A random access channel transmission in the PRACH can then be generated by interlacing the PRBs defining the PRACH.
