    Abstract: A user equipment (UE) may receive information, via radio resource control (RRC) signaling, regarding a search space of a physical downlink control channel (PDCCH) for obtaining downlink control information (DCI) from a radio access network (RAN) node. Based on a slot format (SF) index in the DCI, the UE may determine a slot format for communicating with the RAN node, and communicate with the RAN node in accordance with the slot format. Additionally, a UE may communicate UE capability information, which may include a maximum number of blind decode attempts (BDAs), to the RAN node. The UE may determine shortened channel control elements (sCCEs) to be used, by the RAN node, to transmit shortened downlink control information (sDCI) via a shortened physical downlink control channel (sPDCCH), obtain sDCI by monitoring the sPDCCH in accordance with the determined sCCEs, and communicate with the RAN node in accordance with the sDCI.

    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: Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for a shared channel occupancy time (COT) procedure in a wireless channel of unlicensed spectrum. The shared COT can be utilized among one or more user equipment (UE) and a 5G Node B (gNB). A UE contends for access to the channel to acquire the COT, and transmits in the uplink (UL) according to the UEs time-domain configuration. When the UL transmission does not utilize the entire COT, the UE can signal to the gNB that the COT can be shared. In particular, the UE transmits an indication of a COT boundary that the gNB can use to determine when to transmit DL data in the shared COT. The COT can also be shared between two or more UEs in addition to the gNB.

    Abstract: Some embodiments of this disclosure include apparatuses and methods for a fallback procedure for a 2-step random access channel (RACH) procedure for data transmission in a wireless communication system where the apparatuses and methods include at least generating, by a user equipment (UE), a first signal that includes a first message (MsgA) for a 2-step random access channel (RACH) procedure, transmitting, by the UE, the first signal to a next generation NodeB (gNB), determining, by the UE, whether a 4-step RACH procedure is to be used to further transmit the first signal including the MsgA, and further transmitting, by the UE, the first signal to the gNB using the 4 step RACH procedure based on determining that the 4-step RACH procedure should be used.

    Abstract: A user equipment (UE) can include processing circuitry configured to decode physical broadcast channel (PBCH) information received from a base station (BS). The decoded PBCH information includes a scrambled PBCH payload and an unscrambled bit sequence. A scrambling sequence is generated based on time information signaling within the unscrambled bit sequence. The scrambled PBCH payload is de-scrambled using the scrambling sequence, to obtain master information block (MIB) information. System information block (SIB) information is decoded based on the MIB information. The decoded PBCH information includes cyclic redundancy check (CRC) information. The scrambled PBCH payload and the unscrambled bit sequence can be verified based on the CRC information. The time information signaling includes one or more bits of a system frame number (SFN).

    Abstract: Systems, methods, and apparatuses disclosed herein can operate on an unlicensed spectrum. These systems, methods, and apparatuses can perform a Clear Channel Assessment (CCA) to detect transmissions within the unlicensed spectrum. Thereafter, these systems, methods, and apparatuses can transmit, in response to the unlicensed spectrum being clear of transmissions, one or more first symbols within an uplink (UL) burst portion of a frame structure. The frame structure can include a downlink (DL) burst portion and the UL burst portion separated by gap. These systems, methods, and apparatuses can receive one or more second symbols within the DL burst portion.
