First Claim
Patent Images
1. A method of performing cell reselection, by a user equipment (UE), in a wireless communication system, the method comprising:
- receiving system information including a first offset, a second offset and a third offset;
calculating a ranking for a single-cell point-to-multipoint (SCPTM) cell based on the first offset, the second offset and the third offset; and
performing the cell reselection based on the calculated ranking,wherein the first offset is an offset applied to the SCPTM cell according to whether a frequency to which the SCPTM cell belongs is an inter-frequency or an intra-frequency of a serving cell that the UE is camping on,wherein the second offset is an offset applied temporarily to the SCPTM cell, andwherein the third offset is an offset only applied to the SCPTM cell.

Abstract
Provided are a method for performing cell reselection by a terminal in a wireless communication system and a device for supporting same. The terminal detects a single-cell point-to-multipoint (SCPTM) cell of interest, calculates the ranking of the SCPTM cell of interest, and performs cell reselection on the basis of the calculated ranking. The ranking of the SCPTM cell of interest can be calculated by means of applying a cell-specific priority (CSP).

18. A user equipment (UE) performing cell reselection in a wireless communication system, the UE comprising:
-
a memory; a transceiver; and a processor, connected with the memory and the transceiver, that; controls the transceiver to receive system information including a first offset, a second offset and a third offset; calculates a ranking for a single-cell point-to-multipoint (SCPTM) cell based on the first offset, the second offset and the third offset; and performs the cell reselection based on the calculated ranking, wherein the first offset is an offset applied to the SCPTM cell according to whether a frequency to which the SCPTM cell belongs is an inter-frequency or an intra-frequency of a serving cell that the UE is camping on, wherein the second offset is an offset applied temporarily to the SCPTM cell, and wherein the third offset is an offset only applied to the SCPTM cell.
