Abstract: Techniques are provided for selecting a spatial relation for a physical uplink shared channel (PUSCH) transmission by a user equipment (UE) operating in a multi-transmission reception point (TRP) multi-antenna panel environment. For example, the UE prepares a PUSCH transmission intended for a first TRP of a plurality of TRPs available to the UE in the wireless network, and determines a first antenna port group of a plurality of antenna port groups of the UE that is more directionally aligned with the first TRP than other antenna port groups of the plurality of antenna port groups. The UE further transmits the PUSCH transmission to the first TRP via the first antenna port group using a default spatial relation used for a physical uplink control channel (PUCCH) communication with the first TRP via the first antenna port group.

Abstract: Systems and methods are provided to determine an estimated location of a user equipment (UE). For instance, a UE can provide a positioning request to a node while the UE is in a radio resource control idle (RRC_IDLE) or inactive (RRC_INACTIVE) state. The positioning request can be implemented in a random access channel (RACH) message A (MsgA). The UE can then receive a positioning response from the node. The positioning response can be implemented in a RACH message B (MsgB).

Abstract: Disclosed herein are systems and methods for providing low-latency uplink scheduling requests. For instance, a user equipment (UE) can determine a time of transmission of uplink (UL) data by the UE to a UL device. The UE can further generate control data comprising the determined time of transmission and size information for the UL data. The UE can further provide the control data to the UL device prior to providing the UL data to the UL device. The UE can further receive a UL grant from the UL device. The UE can further provide the UL data to the UL device in response to receiving the UL grant.

Abstract: Some embodiments of this disclosure include apparatuses and methods for uplink panel selection with power saving. In some embodiments, user equipment (UE) may experience a positional change. In response, the UE may deactivate a first communication panel to save power and activate a second communication panel. The UE may then transmit a status message to a communication node indicating the activation and/or deactivation. The node may then register this activation and/or deactivation. In some embodiments, the node may monitor uplink slots from the first and second communication panel to identify the activation and deactivation. For example, if the node detects an absence of an uplink signal within a slot threshold, the node may identify the panel as being deactivated. The node may establishing communications with another panel based on a detected signal and/or the status message.

Abstract: One or more computer-readable media (CRM) are disclosed. The CRM include instructions to, upon execution of the instructions by one or more processors of a base station, cause the base station to: generate a phase tracking reference signal (PT-RS) for phase shift compensation; and transmit the PT-RS across a physical downlink shared channel (PDSCH) using a single-carrier based waveform comprising a carrier frequency. The single-carrier based waveform may be SC-FDE or DFT-s-OFDM.

Abstract: An approach is described for a wireless communication for a fifth generation (5G) or new radio (NR) system. The wireless communication includes a gNode (gNB) configured to indicate a time domain resource allocation within one Discrete Fourier Transform (DFT) size in a downlink control information (DCI), and to transmit a physical downlink shared channel (PDSCH) with a Discrete Fourier Transform-spread-Orthogonal Frequency Division Multiplexing (DFT-s-OFDM) waveform in accordance with the time domain resource allocation within the one DFT size.

Abstract: Systems, apparatuses, methods, and computer-readable media are provided for use in a wireless network for dynamic indication of soft resource availability. Some embodiments are directed to an apparatus in an Integrated Access and Backhaul (IAB) node. The apparatus includes processor circuitry and radio front circuitry. The radio front end circuitry can be configured to receive, from a second IAB node, a slot format indicator (SFI). The SFI can include a slot format entry including a soft symbol indicating availability of a soft resource. The processor circuitry can be configured to use the slot format entry to communicate with a third IAB node, different from the second IAB node, using the soft resource as indicated by the soft symbol.

Abstract: A base station may generate first configuration information to configure a first user equipment (“UE”) to operate using a first bandwidth within a wideband carrier of a cell, generate second configuration information to configure a second UE to operate using a second bandwidth within the wideband carrier of the cell, and cause transmission of the first and second configuration information to the first and second UEs, respectively. The base station may configure the first and second UEs based upon capabilities received from each UE, respectively.
