Abstract: Aspects relate to configuration of phase-tracking reference signals (PT-RSs) in sidelink networks. A sidelink PT-RS configuration for a transmitting wireless communication device may be configured based on a sidelink channel state information (CSI) report received from a receiving wireless communication device. The transmitting wireless communication device may further transmit the sidelink PT-RS configuration to the receiving wireless communication device.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, which may be otherwise known as user equipment (UE) may support repetition of physical downlink control channels (PDCCH) and handling a combined PDCCH candidate associated with multiple search space sets. For example, a UE may combine a first PDCCH candidate corresponding to a first search space set and a second PDCCH candidate corresponding to a second search space set to form a combined PDCCH candidate. The UE may decode the combined PDCCH candidate based on one or more factors, for example, such as a blind decoding PDCCH candidate threshold. As a result, the UE may decode the combined PDCCH candidate in addition to decoding of individual PDCCH candidates, thereby providing increased flexibility for downlink control information (DCI) and improving the reliability of PDCCH.

Abstract: Aspects relate to techniques for enhancing sidelink scheduling information to include a priority assigned to a sidelink transmission. For example, a transmitting wireless communication device may receive sidelink scheduling information scheduling a sidelink transmission from a transmitting wireless communication device to a receiving wireless communication device. The sidelink scheduling information may further include a priority indicator associated with the sidelink transmission. The transmitting wireless communication device may then transmit the sidelink transmission to the receiving wireless communication device based on the scheduling information. The priority indicator may further facilitate hybrid automatic repeat request (HARQ) codebook construction on the sidelink and uplink for the transmission of acknowledgement information of the sidelink transmission.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for maintaining, between a user equipment (UE) and a component of a base station (BS), a mutual understanding of a set of linked physical downlink control channel (PDCCH) candidates if the UE selects to monitor a subset of the linked PDCCH candidates. In one aspect, the UE may monitor the subset of the linked PDCCH candidates, and the UE and the component of the BS may select a reference PDCCH candidate from which to define scheduling information in accordance with the UE monitoring the subset of the linked PDCCH candidates. In some examples, the UE and the component of the BS may select the reference PDCCH candidate in accordance with one or more mutually understood rules or procedures such that the UE and the component of the BS may select a same reference PDCCH candidate.
