A first configuration of a first set of random access channel occasions can be transmitted in a handover command message from a first cell. A second configuration of a second set of random access channel occasions of a second cell can be transmitted. The second set of random access channel occasions can be different from the first set of random access channel occasions. System information of the second cell can include the second configuration of the second set of random access channel occasions. A random access channel preamble can be received on a random access channel occasion. At least one selected from the first set of random access channel occasions and the second set of random access channel occasions can include the random access channel occasion. The first cell can be different from the second cell.

Apparatuses, methods, and systems are disclosed for transmission of a paging message. One apparatus includes a processor and a transceiver that transmits at least one paging occasion (“PO”) configuration in a system information block (“SIB”), where the SIB includes a first quantity of PO configurations. The processor determines a paging frame (“PF”) and a PO identity within the PF and selects a PO configuration, where an amount of POs per PF corresponds to the first quantity of PO configurations included in the SIB and where the selected PO configuration is associated with the determined PO identity. The transceiver transmits a PDCCH carrying paging DCI on a particular paging symbol within a particular paging slot of the determined PF, where the particular paging slot and the particular paging symbol are determined based on the selected PO configuration.

A method, network device and terminal device for providing remaining minimum system information (RMSI) in a wireless network. A method comprises determining whether a SS/PBCH block in the SS burst set configures the RMSI. In response to that the SS/PBCH block configures the RMSI, transmitting one or more repeated RMSI within a first periodicity.

Disclosed are techniques for wireless communication. In an aspect, a position estimation entity configures a sidelink anchor group with sidelink anchor(s), to which respective sidelink PRS pre-configuration(s) are sent. A UE transmits a request to schedule an on-demand sidelink PRS position estimation session of the UE. The position estimation entity provides the UE with assistance data associated with the sidelink anchor group for the on-demand sidelink PRS position estimation session. The UE sends the sidelink anchor group a sidelink PRS trigger to perform a sidelink PRS exchange with some or all of the sidelink anchor group in accordance with the respective sidelink PRS pre-configuration(s).
