Abstract: User equipment (UE) includes processing circuitry coupled to memory. To configure the UE for multi-transmission reception point (TRP) reception, the processing circuitry is to decode radio resource control (RRC) signaling. The RRC signaling includes configuration information configuring a plurality of transmission configuration indication (TCI) states. A media access control (MAC) control element (CE) is decoded, where the MAC CE indicates multiple active TCI states of the configured plurality of TCI states. Multiple received beams are determined using the multiple active TCI states. Downlink information is decoded, where the downlink information originates from multiple TRPs and is received via the determined multiple receive beams associated with the multiple active TCI states.

Abstract: Systems, devices, and techniques for antenna port configuration in wireless communication systems are described. A described technique performed by a user equipment (UE) includes receiving configuration information that determines a bit-width value for an antenna port indication field of a downlink control information (DCI) format; receiving a DCI message that is in accordance with the DCI format; and determining an antenna port configuration for one or more demodulation reference signals based on the DCI message, the configuration information, and the bit-width value.

Abstract: Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may attempt to decode sidelink synchronization signals (SLSSs) received on component carriers (CCs) of a carrier aggregation. In one configuration, synchronization resources for SLSS transmissions may be aligned across the CCs at subframe boundaries in time, restricted to a portion of the CCs, and restricted to a same sub-frame. The UE may, for multiple CCs, determine a priority level for the CC based on indicators in the SLSSs received on the CC. The UE may select, from the CCs on which one or more SLSSs are decoded, the CC for which the determined priority level is highest. The UE may determine a reference timing for sidelink communication based on the one or more SLSSs received on the selected CC.

Abstract: Described is an apparatus of a User Equipment (UE). The apparatus may comprise a first circuitry and a second circuitry. The first circuitry may be operable to encode a Non-scheduled Physical Uplink Control Channel (N-PUCCH) in an Uplink (UL) burst transmission, and to encode a Physical Uplink Shared Channel (PUSCH) in the UL burst transmission. The second circuitry may be operable to initiate the UL burst transmission subject to a Listen-Before-Talk (LBT) protocol on a channel of the wireless network. The UL burst transmission may be initiated without a UL grant received from the eNB.

Abstract: Technology for a user equipment (UE) operable to process scheduled uplink (UL) transmissions is disclosed. The UE can process one or more uplink (UL) grants received from an eNodeB on a downlink (DL) subframe in a first transmission opportunity (TxOP). The UE can determine, based on the one or more UL grants, one or more UL subframes in at least one subsequent TxOP for an UL transmission from the UE. The UE can process the UL transmission for communication on the one or more UL subframes in the at least one subsequent TxOP.

Abstract: Technology for a user equipment (UE) operable to determine a transport block size (TBS) is disclosed. The UE can determine a number of assigned resource elements (REs) in one or more symbols for a transport block. The UE can determine a reference number of REs per physical resource block (PRB) in the transport block based on a reference number of REs for the transport block corresponding to each PRB and an assigned number of PRBs for the transport block. The UE can determine a TBS for the transport block based at least on the reference number of REs per PRB in the transport block. The UE can encode information in a selected transport block for transmission via a physical uplink shared channel (PUSCH) to a Next Generation NodeB (gNB) in accordance with the TBS determined at the UE.

Abstract: Some embodiments of this disclosure include apparatuses and methods for multiplexing uplink (UL) and/or downlink (DL) data transmission packets in user equipment (UE). In some embodiments, the UE may receive a resource configuration from a network node including one or more parameters for establishing a communication channel. The UE may receive a command from the network node indicating a UL grant for packet transmission from the UE. While preparing to transmit a first packet corresponding to the UL grant, the UE may receive a second packet having a higher priority designation, wherein the second packet includes an overlapping symbol with the first packet. The UE may transmit the second packet in view of this higher priority.
