Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for protecting latency-sensitive communications among multi-link devices (MLDs). An access point (AP) MLD may establish multiple communication links with a non-AP MLD and schedule a restricted target wake time (r-TWT) service period (SP) on one of the links (the “r-TWT link”). In some aspects, when a transmit opportunity (TXOP) acquired on a non-r-TWT link overlaps the r-TWT SP, the TXOP may be extended to support an exchange of latency-sensitive traffic on the non-r-TWT link. In some other aspects, any TXOPs occurring on non-r-TWT links may be terminated prior to the start of the r-TWT SP so that latency-sensitive traffic can be exchanged on the r-TWT link during the SP. An AP MLD also may schedule SPs on multiple communication links. In some aspects, the AP MLD may transfer a TWT agreement between the communication links.

Abstract: A communication method for exposing a user plane event includes allowing an NF entity to subscribe to the user plane event by sending a request to a UPF entity through an SMF entity. The SMF entity forwards requests and responses sent between the NF entity and the UPF entity. Because the SMF entity transparently transmits requests and response messages between the NF entity and the UPF entity, the impact on the performance of the SMF entity is minimized.

Abstract: A wireless device may receive packets according to a protocol, such as Bluetooth, and may rapidly react to receive an interfering RF packet instead of dropping the first RF packet and the interfering RF packet, to decrease message delay due to collisions in high device density environments. When a received signal strength indicator (RSSI) difference between the interfering RF packet and the first RF packet exceeds a threshold, the device may detect the interfering packet and resync a portion of its circuitry to lock on to and receive the interfering packet. The wireless receiver may detect the interfering RF packet by detecting one or more of: a specific resync byte sequence, an increase in RSSI, or a phase shift. Additionally, a wireless device may add the specific resync byte sequence to an RF packet of a standard protocol.

Then the WTRU transmits sidelink data on resources indicated by the DCI using the determined MCS table. The WTRU may also receive HARQ feedback on resources indicated by the DCI for HARQ feedback.
