Abstract: Embodiments include a computer readable storage medium, a user equipment, a method and an integrated circuit that perform operations. The operations include generating configured grant uplink control information (CG-UCI), generating hybrid automatic repeat request acknowledgement (HARQ-ACK) information, generating channel state information (CSI) and mapping the CG-UCI, HARQ-ACK, and CSI to resource elements (REs) in resource blocks (RBs) of a configured grant physical uplink shared channel (PUSCH) transmission, wherein the PUSCH transmission includes a demodulation reference signal (DMRS) and wherein the mapping includes one of mapping a concatenated bit sequence or omitting a portion of the CSI.

Abstract: Methods and apparatuses are disclosed for signaling unused channel occupancy time (COT) to the gNB for COT sharing among other UEs. Upon determining that a portion of the maximum COT (MCOT) provided to the UE will be unused, the UE can generate COT sharing information for transmission back to the gNB. The COT sharing information identifies a starting point and a duration (e.g., a number of consecutive slots) of the unused portion of the MCOT. This information is then encoded into configured grant uplink control information (UG-UCI) and transmitted to the gNB as part of the uplink transmission. In aspects, the unused portion may begin part-way through a slot. In this instance, a starting symbol of the unused portion or an ending symbol of the used portion may also be encoded into the uplink transmission. In this manner, unused COT is not wasted, but rather repurposed by the gNB.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing downlink transmission and interlace uplink transmission. For example, some aspects of this disclosure relate to a base station including a transceiver configured to communicate over a wireless network with a user equipment (UE) and a processor communicatively coupled to the transceiver. The processor divides a plurality of candidate Synchronization Signal Block (SSB) positions in a time window into a plurality of groups and communicates, using the transceiver, information associated with the plurality of groups of candidate SSB positions to the UE. The processor further performs a listen-before-talk (LBT) procedure. In response to the LBT procedure being successful, the processor determines a first group of the plurality of groups and transmits, using the transceiver, one or more SSBs on one or more candidate SSB positions of the first group to the UE.

Abstract: A next generation evolved Node B (gNB) configured to provide an unlicensed bandwidth for communications with a user equipment (UE) performs a listen-before-talk procedure to determine an occupation state of busy or idle for the unlicensed bandwidth. When the occupation state is determined by the gNB to be idle, the gNB signals the UE, via a downlink control indicator (DCI), to conduct a channel access measurement (CAM) on the unlicensed bandwidth, the measurement comprising at least one of an energy detection measurement or a signal quality measurement. A measurement report is received from the UE comprising an indication of the occupation state of the unlicensed bandwidth as determined by the UE.

Abstract: Disclosed are systems, methods, integrated circuits and computer readable storage media for configuring time sensitive communications (TSC). The configuring of the TSC includes monitoring, by a user plane function (UPF), a source and destination of packets in a first protocol data unit (PDU) session of a first user equipment (UE) and in a second PDU session of a second UE, pairing a first device side TSN translator (DS-TT) port of the first UE with a second DS-TT port of the second UE when the first PDU session and the second PDU session are served by the same UPF, wherein the pairing is based on the monitoring of the first and second PDU sessions and when the first DS-TT and second DS-TT ports are paired, communicating the packets between the first UE and the second UE in a UE-UE communication without traversing the TSN.

Abstract: A base station of a network provides a user equipment (UE) with information relating to monitoring a Physical Downlink Control Channel (PDCCH) of multiple component carrier (CCs) in a carrier aggregation (CA) scheme. The base station configures a first CC and a second CC of a CA combination for a user equipment (UE) and provides the UE with information for the CA combination, wherein the information comprises an indication whether the first CC and the second CC are collocated.

Abstract: An evolved Node B (eNB) serves as a primary serving cell (PCell) providing a primary component carrier (PCC) in a licensed spectrum to a user equipment (UE) in a carrier aggregation (CA) scheme. A secondary component carrier (SCC) is provided in an unlicensed spectrum. The eNB monitors parameters of bandwidths in the unlicensed spectrum, when at least one of the parameters indicates a change in availability of a select one of the bandwidths, the eNB generates a control indicator defining the change in availability of the bandwidth and broadcasts the control indicator to the UE, wherein the control indicator affects a modification in a transceiver of the UE associated with the bandwidth.

Abstract: A method is disclosed where a user equipment (“UE”) is operating in a carrier aggregation mode and connected to a first cell operating on a licensed band and a second cell operating on an unlicensed band. The method may include the UE performing a carrier sensing operation on the unlicensed band, determining, from the carrier sensing operation, a duration that the unlicensed band will be occupied, refraining from transmitting data to the second cell on the unlicensed band for the duration that the unlicensed band will be occupied and setting a transmitter in communication with the second cell to a low power mode for the duration that the unlicensed band will be occupied.
