Abstract: Aspects of the present disclosure allow a UE to request, in an anchor carrier on one frequency band, a base station to configure and transmit A-TRS in an SSB-less secondary carrier on a different frequency band. The UE transmits, in a first cell served by the anchor carrier, a request for A-TRS. Based on the request, the UE receives, in a second cell lacking SSB transmissions served by the secondary carrier, the A-TRS based on the request. The base station may also control transmission of the A-TRS in the SSB-less secondary cell based on a timer derived from the request. Using the A-TRS, the UE may apply AGC and time/frequency tracking loop operations prior to receiving a PDSCH in the SSB-less secondary cell, thereby improving reception performance of downlink data transmissions in the secondary carrier. Thus, network energy savings provided by SSB-less secondary carriers may be obtained in inter-band CA.

Abstract: Aspects of the present disclosure allow for more efficient rate matching by allowing a triggered A-ZP-CSI-RS set to support rate matching around multiple slots. Aspects of the present disclosure may allow a triggered A-ZP CSI-RS set to be applied to less than all scheduled PDSCH slots when DCI schedules PDSCH on multiple slots. Aspects of the present disclosure may extend CSI-RS resource mapping to span multiple adjacent slots. In another instance, aspects of the present disclosure allow a resource mapping configuration to indicate an initial symbol of a plurality of symbols spanning the plurality of slots for a respective A-ZP-CSI-RS resource. Doing so also allows a PDSCH transmission in a slot among the plurality of slots using a rate matching pattern associated with a set of A-ZP-CSI-RE resources to be received. In addition, aspects of the present disclosure can also add periodicity to A-ZP-CSI-RS resource set configuration.

Abstract: Wireless communications systems, apparatuses, and methods are provided. A method of wireless communication performed by a user equipment (UE) includes receiving, from a network unit, a reference signal in a first frequency band, measuring the reference signal, and transmitting a communication in the first frequency band based on the measurement, wherein the UE is configured with a supplementary uplink (SUL) carrier on the first frequency band.

In some aspects, a mobile station may receive, from a base station, an indication of a relaxed physical downlink shared channel (PDSCH) hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback timeline associated with a dynamic spectrum sharing (DSS) deployment in which a first radio access technology (RAT) and a second RAT share a same frequency band. The mobile station may receive, from the base station, a PDSCH associated with the first RAT. The mobile station may transmit, to the base station, PDSCH HARQ-ACK feedback for the PDSCH associated with the first RAT based at least in part on the relaxed PDSCH HARQ-ACK feedback timeline associated with the DSS deployment.
