Abstract: A user equipment (UE) may be configured/scheduled with uplink (UL) transmissions over multiple channels. Each UL transmission is aligned with a boundary of a UE fixed period frame (FFP). For each UL transmission, the UE may determine whether a gNB has initiated a channel occupancy time (COT) in a gNB FFP over a corresponding channel. If the COT is not initiated, the UE may initiate a COT in the UE FFP over the channel when the channel is available, by transmitting a corresponding UL transmission over the channel in the UE FFP. The UE may send, to the gNB, information indicating UE-initiated COT channel(s) of the multiple channels over which COT(s) have been initiated by the UE. The gNB may provide feedback for the UL transmissions based on the information.

Abstract: A user equipment (UE) may perform partial sensing during a sidelink (SL) discontinuous reception (DRX) inactive time of the UE over a partial sensing occasion to obtain a sensing result. The partial sensing may include periodic based partial sensing (PBPS) or contiguous partial sensing (CPS), and the partial sensing occasion may include a sensing occasion determined on a most recent sensing occasion for PBPS or a minimum number of slots for CPS. The UE may determine, based on at least the sensing result, available resources for SL transmissions, and transmit a SL transmission over a resource of the available resources.

Abstract: A reduced capability (RedCap) user equipment (UE) receives a system information block (SIB), in a first initial downlink (DL) bandwidth part (BWP) based on a first configuration within a master information block (MIB) received by the RedCap UE, the SIB indicating a second configuration for a second initial DL BWP, wherein the RedCap UE has a maximum bandwidth capability less than a minimum bandwidth capability for a non-RedCap UE, and wherein a bandwidth of the second initial DL BWP is no larger than the maximum bandwidth capability; receives transmissions in the first initial DL BWP before an initial access procedure; and receives transmissions in the second initial DL BWP during and after the initial access procedure in response to the RedCap UE transmitting a random access channel (RACH).

Abstract: According to embodiments, a first UE (e.g., UE A) receives from a second UE (e.g., UE B) a sidelink control information (SCI) in a first slot. The SCI comprises a resource reservation for a shared channel. The resource reservation indicates a set of frequency resources and a time resource assignment. The first UE transmits to the second UE a conflict indicator on resources of a feedback channel. The resources of the feedback channel include a second slot for transmitting the conflict indicator. A location of the second slot is based on one of the first slot or a slot indicated by the time resource assignment. The conflict indicator indicates a potential resource conflict or a detected resource conflict on at least one of the set of frequency resources or the time resource assignment indicated by the resource reservation.

Abstract: A user equipment (UE) may determine, based on a criterion, whether to indicate, to a gNB, that it is a reduced capability (RedCap) UE during or after a random access (RA) procedure, and indicate that it is the RedCap UE during or after the RA procedure according to a determination result. The RedCap UE has a reduced quantity of receive branches or a reduce bandwidth than a non-RedCap UE. The gNB may determine whether a first message received during the RA procedure indicates that the UE is the RedCap UE. When the first message indicates the UE as the RedCap UE, the gNB sends a second message to the UE during the RA procedure using a coverage recovery technique. When the first message does not indicate the UE as the RedCap UE, the gNB determines whether the UE is the RedCap UE after the RA procedure is completed.

Abstract: A first user equipment (UE) reserves a resource from a resource pool for transmission of sidelink data associated with a packet priority, and transmits a location of the reserved resource, an indicator indicating whether a reservation priority is assigned to the sidelink data, and a priority value that is associated with the packet priority or the reservation priority. A second UE receives the location of the reserved resource, the indicator and the priority value, and based thereon performs sidelink communication. A UE may also select, from a resource pool based on a packet priority of sidelink data to be transmitted, a subset of resources usable by the UE, and transmit the sidelink data using a resource selected from the subset of resources. The resource pool includes one or more subsets of resources each of which is associated with a set of priority values.

Abstract: Embodiments are provided herein for determining a synchronizing master for device-to-device (D2D) communication in a cellular network environment. In an embodiment, a user equipment (UE) receives a discovery signal comprising a timing reference, and determines a transmitter of the discovery signal. In accordance with the determination of the transmitter of the discovery signal, the UE performs one of synchronizing to the timing reference in the discovery signal and transmitting a second discovery signal. The UE performs the synchronizing to the timing reference if the transmitter of the discovery is a cellular network. Alternatively, the UE transmits the second discovery signal upon determining that the transmitter of the discovery signal is a second UE that is out of coverage of a cellular network.

Abstract: User Equipments (UEs) may be assigned a set of aggregated component carriers for downlink carrier aggregation and/or carrier selection. Some UEs may be incapable of transmitting uplink signals over all component carriers in their assigned set of aggregated component carriers. In such scenarios, a UE may need to perform SRS switching in order to transmit SRS symbols over all of the component carriers. Embodiments of this disclosure provide various techniques for facilitating SRS switching. For example, a radio resource control (RRC) message may be used to signal a periodic SRS configuration parameter. As another example, a downlink control indication (DCI) message may be used to signal an aperiodic SRS configuration parameter. Many other examples are also provided.

Abstract: A user equipment (UE) in a frame based equipment (FBE) mode may determine that a communication channel in an unlicensed spectrum is available for use, and transmit, in the communication channel, a transmission to a gNB in a fixed frame period (FFP) associated with the UE to initiate a channel occupancy time (COT) by the UE in the FFP. The transmission starts at the beginning of the FFP and ends before an idle period within the FFP. The gNB receives the transmission and, based thereon, determines that the UE has initiated the COT. The gNB may acknowledge or reject initiation of the COT by the UE.

Abstract: Example methods and apparatus for reducing power consumption of user equipment (UE) are described. One example method includes receiving an indication by the UE for determining physical downlink control channel (PDCCH) candidate ordering for a plurality of PDCCH candidates in a PDCCH search space. The UE determines a first PDCCH candidate from among the plurality of PDCCH candidates based on the indication. In response to determining that downlink control information (DCI) for the UE is not found in the first PDCCH candidate, the UE determines a second PDCCH candidate from among the plurality of PDCCH candidates based on the indication. In response to determining that the DCI for the UE is found in the second PDCCH candidate, the UE processes the DCI.

Abstract: A method and system for including a base station that configures a first user equipment (UE) that is in a radio resource control connected state with the base station. The UE is configured to be a synchronization source and transmit a first device-to-device synchronization signal (D2DSS) by using a synchronization resource that comprises a time resource, a frequency resource or a time and frequency resource. The base station instructs the first UE to transmit the first D2DSS using the synchronization resource. The base station signals the UE to configure the UE separately from the signal to transmit the D2DSS, and both of the signals are performed with radio resource control signaling from the base station to the UE.
