Method for transmitting and receiving signals based on segmented access scheme and method for allocating sequence for the same
DC CAFC
First Claim
1. A method for a specific user equipment (UE) to transmit a signal via a random access channel, the method comprising:
- selecting one random access preamble sequence set from among predetermined random access preamble sequence sets considering at least one of a size of information to be transmitted by the specific UE and a degree of a path loss;
randomly selecting a specific sequence within the selected random access preamble sequence set; and
transmitting the selected sequence via the random access channel.

Abstract
A segmented access based signal transmitting/receiving method and a sequence allocating method for the same are disclosed. According to one embodiment of the present invention, a method of transmitting a signal of a user equipment in a communication system includes selecting a channel in accordance with at least one selected from the group consisting of a signal attenuation extent of a downlink signal to the αser equipment and a speed of the user equipment from channels differently provided based on at least one selected from the group consisting of the signal attenuation extent of the downlink signal and the speed of the user equipment and transmitting the signal using the selected channel.
