Title: METHOD AND APPARATUS FOR DETERMINING DELAY BETWEEN RANDOM ACCESS CHANNEL AND DOWNLINK CONTROL CHANNEL
Abstract:
A method is provided for determining delay between random access channel and downlink control channel in random access procedures. The method comprises receiving from a base station, by a user equipment, information related to one or more delay(s) between a random access channel and one or more repetition period(s) of a downlink control channel for the user equipment; sending to the base station, by the user equipment, the random access channel transmitted in a repetitive form; receiving, by the user equipment, the one or more repetition period(s) of the downlink control channel, wherein each of the one or more repetition period(s) of the downlink control channel is transmitted according to a corresponding one of the delay(s); and determining, by the user equipment, the one or more delay(s) based at least on the information related to the delay(s).
