Abstract: According to embodiments, a UE receives, from a source cell, a mobility pre-configuration radio resource control (RRC) message for random-access channel (RACH)-less access. The mobility pre-configuration RRC message indicates target timing advance (TA) assistance information. The UE receives, from the source cell, a lower layer target access command. The lower layer target access command indicates a most updated or latest network-updated time sensitive dynamic TA assistance information. The UE determines a target cell TA of a target cell based on a latest source cell TA of the source cell, a latest measured timing difference between reference signals (RSs) from the source cell and from the target cell, the most updated or latest network-updated time sensitive dynamic TA assistance information, and the target TA assistance information. The UE performs the RACH-less mobility access to the target cell based on the target cell TA.

Abstract: Embodiments of this disclosure provide an efficient mechanism for re-ordering media access control (MAC) service data units (MSDU) segments by including link-specific MAC addresses and link-independent sequence control fields in MAC headers appended to MAC protocol data unit (MPDU) payloads within which the MSDU segments are encapsulated prior to transmitting the MPDU payloads over multiple aggregated 802.11 links. Each sequence control field may include a link-independent sequence number that indicates a relative position of a corresponding MSDU within the sequence of MSDUs of the same traffic stream. Additionally, when the MSDU segment is an MSDU fragment, the sequence control field may further include a link-independent fragment number that indicates a relative position of the corresponding MSDU fragment within a sequence of MSDU fragments of the MSDU that was subject to fragmentation.

Abstract: A method for operating a radio link control (RLC) entity of a communication equipment includes the RLC entity being configured for receiving data over a plurality of logical channels, the RLC entity receiving RLC protocol data units (PDUs) generated by a plurality of transmitting RLC entities over a plurality of logical channels, generating RLC service data units (SDUs) from the RLC PDUs, and delivering the RLC SDUs to an upper layer.

Abstract: A method includes: determining, by an access point based on remaining quantities of electricity and/or location information of all stations in at least one station group in a basic service set, an identifier of a type-1 station in each of the at least one station group and available time window information that corresponds to each type-1 station, and generating a notification message including relay enabling information of the at least one station group, relay enabling information of each station group includes identifiers of at least two type-1 stations in the station group and the available time window information of each type-1 station; and broadcasting, by the access point, the notification message in the basic service set.
