Abstract
Methods and apparatuses of UE for an efficient neighbor cell search in a wireless communication network. A method of a UE comprises: receiving system information including time instance information for performing measurements on neighboring cells; identifying a time instance included in the time instance information; determining, based on a comparison between a current absolute time and the time instance, whether to perform the measurements on the neighboring cells; and skipping performing the measurements on the neighboring cells based on a determination that the current absolute time is before the time instance.
Claims6
A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving a system information block (SIB);
- identifying a distance between the UE and a reference location of a serving cell based on the SIB;
- identifying whether the distance is shorter than a distance threshold;
- identifying that the SIB includes time information on when the serving cell is going to stop serving an area currently covered by the serving cell;
- and
- in case that (i) the distance is not shorter than the distance threshold and (ii) a current absolute time is before a stop time indicated by the time information, performing a measurement for at least one cell.
A user equipment (UE) comprising:
- a transceiver configured to
- receive a system information block (SIB);
- and
- a processor operably coupled to the transceiver, the processor configured to:
- identify a distance between the UE and a reference location of a serving cell based on the SIB;
- identify whether the distance is shorter than a distance threshold;
- identify that the SIB includes time information on when the serving cell is going to stop serving an area currently covered by the serving cell;
- and
- in case that (i) the distance is not shorter than the distance threshold and (ii) a current absolute time is before a stop time indicated by the time information, perform a measurement for at least one cell.
A base station (BS) comprising:
- a processor;
- and
- a transceiver operably coupled to the processor, the transceiver configured to
- transmit, to a user equipment (UE), a system information block (SIB) to the UE that includes time information on when a serving cell associated with the BS is going to stop serving an area currently covered by the serving cell,
- wherein, in case that (i) a distance between the UE and a reference location of the serving cell associated with the BS is not shorter than a distance threshold and (ii) a current absolute time is before a stop time indicated by the time information, a measurement for at least one cell is performed, and
- wherein the reference location of the serving cell is based on the SIB.
