    Abstract: A communication system that includes mobile user equipment and a communication network is provided. The communication network includes a first base station communicating with the user equipment according to a first defined radio frame format with a first sequence of radio frames each having the same length and each being allocated a respective first System Frame Number (SFN) to sequentially number the radio frames of the first sequence. A second base station is provided to communicate with the user equipment according to a second defined radio frame format including a second sequence of radio frames each having the same length and each being allocated a respective second SFN such that the radio frames of the second sequence are sequentially numbered. A radio signal includes first information indicative of a difference between the first and second SFNs at a particular time and second information usable with the first information.

    Abstract: Methods and apparatuses in a wireless communication system. A method of operating a user equipment BS includes generating a first indicator requesting a report of a set of sidelink (SL) discontinuous reception (DRX) configurations for SL communications among user equipments (UEs); transmitting a downlink signal including the first indicator; receiving an uplink signal including the report of the set of the SL DRX configurations based on the first indicator indicating that the report of the set of the SL DRX configurations is requested; and configuring, based on the report of the set of the SL DRX configurations, a network DRX configuration for a Uu interface between a UE and a network entity including the BS.

    Abstract: A random access channel (RACH)-less conditional cell switch is provided. A user equipment (UE) receives and stores a candidate cell configuration including an execution condition of a conditional cell switch to the candidate cell. The UE selects the candidate cell as a target cell for the conditional cell switch on determination that the execution condition is met. The UE determines whether a valid timing advance (TA) and a valid uplink (UL) grant for initial UL transmission to the target cell is available. When a valid TA and a valid UL grant are available, UE transmits initial UL transmission to the target cell using the valid TA and the valid UL grant. When a valid TA is unavailable, the UE performs random access procedure to the target cell. When a valid UL grant is unavailable, the UE transmits a scheduling request to the target cell.
