Abstract: Some embodiments are disclosed for Uplink (UL) Transmission (Tx) switching in a wireless network. Some embodiments a base station (BS) can receive first UL Txs, transmit, a dynamic trigger signal for UL Tx switching, where a number of configured UL Tx switching bands, M, is greater than a maximum number of UL Tx chains, N, where M and N are integers. The BS can receive second UL Txs according to the dynamic trigger signal. In some examples, the first UL Txs and the second UL Txs correspond to a first pair of bands of the M configured UL Tx switching bands, or the first UL Txs correspond to a first pair of bands of the M configured UL Tx switching bands, and the second UL Txs correspond to one band of the first pair of bands and a different band of the M configured UL Tx switching bands.

Abstract: Some aspects relate to apparatuses and methods for implementing mechanisms for providing signaling and procedures to indicate a mode of communication of a wireless communication system. For example, a base station is configured to determine a mode of communication for a cell associated with the base station. The mode of communication can include one of a full-duplex mode or a half-duplex mode. The base station can further generate system information to enable initial access by a user equipment (UE) to the cell. A portion of the system information can indicate the mode of communication for the cell. The base station can also transmit the system information to the UE.

Abstract: The exemplary embodiments relate to a computer-readable storage medium, a device, an integrated circuit and a method that perform operations related to a first user equipment (UE) configured with a sidelink (SL) connection with a second UE. The operations include generating an SL counter check request including at least a first count for data transmissions from the first UE to the second UE as determined by the first UE. The operations further include transmitting the request to the second UE and receiving a counter check response to the request, the response comprising at least a second count for data transmissions from the first UE to the second UE as determined by the second UE. The operations further include determining a first difference between the first count and the second count and, when the first difference exceeds a threshold, releasing the SL connection with the second UE.

Abstract: Aspects are described for a user equipment (UE) comprising a transceiver configured to enable wireless communication with a base station and a second UE, and a processor communicatively coupled to the transceiver. The processor is configured to determine a set of subcarriers from two physical resource blocks (PRBs). The set of subcarriers includes only one subcarrier or more than two subcarriers. The processor is further configured to transmit, using the first set of antenna ports of the transceiver, channel state information reference signals (CSI-RSs) in a set of resource elements (REs) to the second UE. The set of REs occupies the set of subcarriers.

Abstract: A base station can include a transceiver and a processor communicatively coupled to the transceiver. The transceiver can enable wireless communication with a user equipment (UE) by a first component carrier (CC) in a first cell managed by the base station in a carrier aggregation (CA) wireless communication system. The processor can generate a system scheduling message to be transmitted on the first CC to the UE in the first cell, where the system scheduling message comprises a schedule of monitoring occasions for system information of a second CC by the UE in a second cell. Afterwards, the processor can transmit the system scheduling message on the first CC to the UE.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing a beam pairing procedure between a transmission UE and a receiver UE. The transmission UE and the receiver UE can configure a set of beam patterns to be used in the beam pairing procedure. The set of beam patterns can include one or more transmission beams of the UE, and one or more receiving beams of the receiver UE. The transmission UE can transmit one or more sidelink reference signals to the receiver UE, and the receiver UE can perform signal strength measurements of the one or more sidelink reference signals. Based on the signal strength measurements, either the transmission UE or the receiver UE can make the selection of the transmission beam and the corresponding receiving beam for the beam pairing procedure.

Abstract: Current 5G provisions for wireless communications do not allow for the differentiation of channel access by User Equipments (UEs) with different priorities. Approaches are described by which priority access for UEs in a controlled environment using frame based equipment (FBE), and in particular for different UEs or the same UE that has different configured grants. The approaches are particularly helpful for ultra-reliable low-latency communication (URLLC) UEs. In one approach, the UE performs a clear channel assessment (CCA) in an idle period before the fixed frame period (FFP), followed by a channel access priority test. In an alternative approach, the UE performs a channel access priority test before the UE performs a clear channel assessment (CCA) in an idle period before the fixed frame period (FFP). Other approaches include setting the fixed frame period length to different sizes for each UE, using a random number of skipped fixed frame periods, and the gNB configuring UEs with multiple semi-static channel access mode parameters.
