Abstract: Wireless communication devices, systems, and methods related to mechanisms to implement improved interference tracking over time. A BS may transmit information to a UE that allows the UE to quantize channel measurements into interference states. The UE may transmit an interference change report as triggered by an event, such as an interference metric exceeding a threshold after quantizing into the interference states. This enables the system to capture and respond to abrupt changes. Further, the interference change report may include historic interference information. The UE may include statistics based on the historic interference information. The UE may further be triggered to transmit an interference change report in response to a BS requesting it, or in response to a configured period of time elapsing. The UE may further include MCS information predicted for one or more future time periods based on historic information, which the BS may use in scheduling.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may transmit an expiration indication to a receiving device as part of a scheduling message for a transport block. The expiration indication may provide information related to an expiration time for the transport block. If the expiration time is reached prior to successful reception by a receiving device, the receiving device may assume that the transport block has expired and may refrain from transmitting a retransmission grant, or may empty a hybrid automatic repeat request (HARM) buffer associated with the transport block. If the transmitting device fails to successfully receive an indication from the receiving device of a successful reception of the transport block prior to the expiration period, the transmitting device may also assume that the transport block has expired.

Abstract: Some aspects of the present disclosure disclose methods and systems related to managing overlapping semi-persistent scheduling (SPS) configured physical downlink shared channel (PDSCH) transmission occasions. In some aspects, a user equipment (UE) may identify one or more semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) transmission occasions in a slot and receive, from a base station (BS) and via a physical downlink control channel (PDCCH), a semi-persistent scheduling (SPS) release configured to release at the UE a SPS configuration including a configuration index. The UE may then perform SPS PDSCH transmission occasions collision avoidance procedures while releasing the SPS PDSCH transmission occasion to manage overlapping SPS PDSCH transmission occasions.

Abstract: Methods, systems, and devices for wireless communication are described. A first user equipment (UE) may receive a control message that includes an indication to mute communications between the first UE and a second UE. The indication may be applicable to at least one communication link between the first UE and the second UE. The indication may include an identifier of the first UE, an identifier of the second UE, or an identifier of the at least one communication link. The first UE may receive the indication based on a power status of the first UE, a power status of the second UE, a reliability metric associated with the at least one communication link, or an interference metric associated with a network entity. Accordingly, the first UE may determine that the at least one communication link is muted for a time duration based on the indication.
