METHOD AND APPARATUS FOR PERFORMING RADIO ACCESS WITH DELAY IN A WIRELESS COMMUNICATION SYSTEM
First Claim
1. A method of performing a radio access procedure in a wireless communication system using a number of orthogonal frequency division multiple (OFDM) symbols, the method performed by a user equipment (UE) and comprising:
- transmitting a radio resource control (RRC) connection request message to a network, wherein an establishment cause of the RRC connection request message is set to be delay tolerant or low priority;
receiving information associated with a first wait time included in an RRC connection reject message or an RRC connection release message from the network; and
performing a radio access to the network with a delay which is determined based on a lower bound of the first wait time and a upper bound of the first wait time,wherein the lower bound of the first wait time and the upper bound of the first wait time are indicated by the information on the first wait time.

Abstract
In one design, a method to change a network-assigning mechanism and to use a distributed UE-selecting mechanism with the minimum possible information transferred from the network to the UE is proposed. In particular, it provides mechanism to define a lower bound and an upper bound for the extended wait time. For instance, the method comprises transmitting a RRC connection request message to a network, wherein an establishment cause of the RRC connection request message is set to be delay tolerant or low priority; receiving information associated with a first wait time included in an RRC connection reject/release message from the network; and performing a radio access to the network with a delay which is determined based on a lower bound of the first wait time and a upper bound of the first wait time.

10. A method of performing a radio access procedure in a wireless communication system using a number of orthogonal frequency division multiple (OFDM) symbols, the method performed by a user equipment (UE) and comprising:
-
transmitting a radio resource control (RRC) connection request message to a network, wherein an establishment cause of the RRC connection request message is set to be delay tolerant or low priority; in response to the RRC connection request message, receiving an RRC connection reject message from the network including first information associated with an extended wait time, wherein the first information includes a first portion and a second portion; determining a lower bound for the extended wait time and an upper bound for the extended wait time by using the first information associated with the extended wait time; drawing a random number from a uniform distribution between the lower bound and the upper bound for the extended wait time; starting an extended wait timer according to the drawn number; and performing an access class (AC) barring procedure after the extended wait timer is expired. - View Dependent Claims (11, 12, 13, 14)
