Methods and devices for assisting cell reselection and paging
Method, systems and devices for wireless communication. The method includes receiving, by a user equipment (UE), a dedicated signal comprising physical cell identifier (PCI) range information and determining whether a preset condition has occurred. In response to determining that the preset condition has occurred, the method includes setting, by the UE, the PCI range information in the dedicated signal as invalid. In response to determining that the preset condition has not occurred, the method includes replacing, by the UE, previously received PCI range information by the PCI range information in the dedicated signal, and using the PCI range information in the dedicated signal to assist cell reselection.
1 . A method for wireless communication, comprising:
transferring physical cell identifier (PCI) range information in a signal between a radio access network (RAN) node and a user equipment by performing:
sending the signal from the RAN node to the user equipment,
wherein the signal comprises the PCI range information, and
wherein the PCI range information comprises a list of ranges of PCIs for each of a plurality of public land mobile network identifiers (PLMN IDs), each range of PCIs for an intra-frequency or at least one inter-frequency.
2 . The method of claim 1 , wherein:
the signal comprises a radio resource control (RRC) release message.
3 . A non-transitory computer program product comprising a computer-readable program medium code stored thereupon, the code, when executed by a processor, causing the processor to perform the method of claim 1 .
4 . The non-transitory computer program product of claim 3 , wherein:
the signal comprises a radio resource control (RRC) release message.
5 . A wireless communication apparatus comprising a processor and a memory, wherein, when the processor reads instructions from the memory, the processor is configured to perform:
receiving, by a user equipment, a signal form a radio access network (RAN) node, wherein the signal comprises physical cell identifier (PCI) range information; and
determining, by the user equipment, the PCI range information for cell reselection;
wherein the PCI range information comprises a list of ranges of PCIs for each of a plurality of public land mobile network identifiers (PLMN IDs), each range of PCIs for an intra-frequency or at least one inter-frequency.
6 . The wireless communication apparatus of claim 5 , wherein:
the signal comprises a radio resource control (RRC) release message.
