Abstract: A cellular base station (BS) which transmits more flexible downlink control information (DCI) to the UE, and a UE capable of receiving and processing a received DCI message. The DCI message may have a DCI format of 0_1 or 0_2 and further may comprise an UL-SCH set to 0, a CSI request field of all 0s and an SRS request field having a nonzero value. The DCI message may indicate to the UE that the UE should: 1) transmit an aperiodic SRS corresponding to SRS request; and 2) that the UE should not transmit on the PUSCH. The DCI may include existing fields that specify either a slot offset or beam information useable when transmitting the aperiodic SRS. The base station may also generate a DCI message with an SRS trigger that is targeted to a plurality of UEs in a group, or a plurality of groups of UEs, for greater efficiency.

Abstract: Techniques discussed herein can facilitate transmission and reference signals (RS) associated with layer-1 (L1) operations outside of a configured carrier bandwidth (CBW) of a user equipment (UE). One example aspect is a UE with one or more processors configured to transmit UE capability information. The UE capability information includes a frequency separation threshold, where the frequency separation threshold represents a frequency separation from a CBW of the UE. The one or more processors are further configured to receive a RS within the frequency separation threshold and outside of the CBW, and subsequently perform a L1 operation based on the RS.

Abstract: Disclosed are techniques for reducing likelihood of Random Access Channel (RACH) transmission blockages and thereby facilitate an initial access procedure for new radio (NR) unlicensed spectrum (NR-U) operation in a fifth generation (5G) wireless communication system including an NR node. In some embodiments, a parameter generated by a gNB and received by a UE indicates that, from among a set of consecutive RACH Occasions (ROs), a gap is available for performing a listen-before-talk (LBT) procedure before commencing a RACH transmission.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to determine a default beam for a dedicated PUCCH/SRS in a CC. The UE may determine a pathloss RS has been configured in the CC, e.g., responsive to the UE determining that spatial relationship information for a default transmission beam has not been configured and determine the default beam for transmissions based, at least in part, on the (configured) pathloss RS. Additionally, responsive to determining that the pathloss RS has not been configured in the CC, the UE may determine that no CORESETs/TCI states for a PDSCH in the CC have been configured and determine the default beam for transmissions based, at least in part, on a default transmission beam in another CC, a CC index, a PRACH procedure; a PUSCH transmission; an SRS transmission, and/or a PUCCH transmission.

Abstract: Systems, methods, and circuitries are provided for performing sidelink communication. An example method generates SCI stage 1 and stage 2 for transmitting a transport block (TB) to a user equipment device (UE). The method includes determining the type of sidelink communication for transmitting the TB. An SCI stage 2 format is selected based on the type of sidelink communication. An SCI stage 2 payload is encoded in accordance with the selected SCI stage 2 format. The selected SCI stage 2 format value is encoded in an SCI stage 1 payload. The SCI stage 1 payload and SCI stage 2 payload are transmitted to the UE.

Abstract: The present application relates to devices and components including apparatus, systems, and methods to perform SRS transmission when a UE supports SRS Tx antenna port switching. In an example, a determination is made about whether a scheduled SRS transmission impacts a scheduled DL reception given the SRS Tx antenna port switching. If so, the SRS transmission and/or the DL reception are changed. In a further example, the UE can supports an SRS TA capability in conjunction with the SRS Tx antenna port switching capability. In this example, SRS TA can be applied to a scheduled SRS transmission.
