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: 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: Disclosed are systems, methods, and one or more computer-readable media (CRM) storing instructions for the triggering of a channel state information reference signal (CSI-RS) by user equipment (UE) in a wireless cellular network. The UE measures a downlink reference signal. The UE also determines a condition for triggering a channel state information reference signal (CSI-RS) is satisfied based on the downlink reference signal. Then, the UE transmits a request for a base station of the wireless cellular network to provide the CSI-RS to the UE based on the condition being satisfied.
