Abstract

Provided in the present invention are a method performed by user equipment, and user equipment. A method performed by user equipment is a method of an RRC connection re-establishment procedure performed by user equipment (UE), and includes the following steps: triggering or initiating, by the UE, an RRC connection re-establishment procedure; during initiation of the RRC connection re-establishment procedure, starting, by the UE, a timer T 311 , and performing cell selection or relay selection; and in the case that the UE has selected a suitable cell or the UE has selected a suitable relay, stopping, by the UE, T 311 , wherein the suitable cell is a cell of which a measured value or a level value meets a cell selection rule, and the suitable relay is a relay of which a measured value or a level value meets a relay selection rule.

Claims (15)

1. A method performed by user equipment, the method comprising:

starting a first timer and performing a selection, upon initiating a Radio Resource Control (RRC) connection re-establishment procedure;

upon performing the selection, stopping the first timer and starting a second timer, regardless of whether the selection is a suitable cell selection or a suitable relay selection, wherein,

in a case where the suitable cell selection is performed, the second timer is started with use of a first value, and

in a case where the suitable relay selection is performed, the second timer is started with use of a second value; and

stopping the second timer upon reception of an RRC reestablishment message.

2. A user equipment, comprising:

a processor; and

a memory storing instructions,

wherein the instructions, when run by the processor, cause the user equipment to:

start a first timer and perform a selection, upon initiating a Radio Resource Control (RRC) connection re-establishment procedure;

upon performing the selection, stop the first timer and start a second timer, regardless of whether the selection is a suitable cell selection or a suitable relay selection, wherein,

in a case where the suitable cell selection is performed, the second timer is started with use of a first value, and

in a case where the suitable relay selection is performed, the second timer is started with use of a second value; and

stop the second timer upon reception of an RRC reestablishment message.
