Abstract:
A DRX/eDRX cycle may include a single PFW located in one of the non-anchor hopping frames and used to transmit a paging message. When the LBT procedure fails for the non-anchor hopping frame in which the PFW is located, transmission of the paging message may be delayed. Postponing the transmission of the paging message until a subsequent DRX/eDRX cycle be detrimental since the UE may not receive the change in system information at the next modification boundary. Thus, there is a need for paging mechanism the increases the chance of a UE receiving a paging message during a DRX/eDRX cycle. The present disclosure provides a paging mechanism that uses a PSFW with a PFW in each non-anchor hopping frame within a DRX/eDRX cycle. Hence, the chance of a UE receiving a paging message and hence the change in system information may be increased.
