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 pay load based on the resources allocated for the MsgA preamble and the mapping.

Abstract: A mode of operation is provided for user equipment (UE) communicating in unlicensed carrier (e.g., NR-unlicensed). The UE is configured to operate in one or more modes of operation, including FBE and LBE. The UE can be configured to operate in FBE, where the equipment has a fixed frame period according to CCA, or in LBE, where the equipment determines whether the channel is idle or not and transmits only when the channel is clear. The UE is configured to operate in a mode of operation to be used in the communicating with a communication network (e.g., a cellular network), where the UE can transmit and/or receive one or more listen before talk (LBT) messages with the communication network through a Radio Access Network (RAN) based on the mode of operation.

Abstract: Systems and methods of in-sync/out-of-sync (IS/OOS) determination in the unlicensed band are described. Reference signals are measured on the unlicensed band. If the UE determines that at least one of the reference signals is missing, the IS/OOS condition is evaluated on that basis. If the missing signals are ignored when determining the IS/OOS condition, and the IS/OOS condition is unable to evaluated, the L1 sends an indication to the RRC layer. If the number of indications exceeds a threshold, the UE performs re-establishment or sends a report to the base station for adjustment of the reference signal resources. If the missing signals are counted, the missing signals are weighted based on proximity to the noise floor or a number of adjacent signals that are missing.

Abstract: Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for use in a wireless network for improving configured grant for new radio (NR) unlicensed. For example, some embodiments are directed to an electronic device including radio front end circuitry and processor circuitry. The processor circuitry can be configured to receive, using the radio front end circuitry, a message from a base station and, based on the received message, determine whether to use a lowest Channel Access Priority Class (CAPC) or a highest Units (SDUs) that are multiplexed in one or more MAC Protocol Data Units (PDUs) for an uplink (UL)transmission. The processor circuitry transmits, using the radio front end circuitry, the MAC PDU to the base station.

Abstract: Techniques are provided for determining and processing uplink listen before talk (LBT) failures, including the determination of a consistent and systematic LBT failure associated with uplink transmissions in new radio (NR) operating over unlicensed spectrum. For example, a user equipment (UE) identifies a plurality of transmission occasions to be performed by the UE over the unlicensed spectrum. The UE further performs a plurality of listen before talk (LBT) procedures associated with respective ones of the plurality of transmission occasions to be performed by the UE, and tracks a number of LBT failures during the performance of the plurality of LBT procedures, wherein a LBT failure occurs due to a channel used for the associated LBT procedure being busy or when an LBT backoff is still running from a previous LBT failure. The UE further implements a recovery procedure in response to the LBT failures exceeding a predetermined threshold within a predetermined time period.

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 PD SCH 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: Disclosed are systems, apparatuses, methods, and computer-readable media for use in a wireless network for facilitating radio access synchronization. The method includes receiving, from a user equipment (UE) a message having a media access control (MAC) control element (CE) format and comprising a MAC protocol data unit (PDU) structure, the message being formed by multiplexing one or more MAC service data units (SDUs). The method further includes generating a response message to the received message by multiplexing a MAC random access response (RAR) with one or more MAC SDUs. The method then transmits the response message to the UE

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.
