Techniques for transmitting random access signaling for system access are described. In an aspect, random access signaling may be sent based on at least one transmission parameter having 5 different values for different user equipment (UE) classes. At least one parameter value may be determined based on a particular UE class, and the random access signaling may be sent based on the determined parameter value(s). The random access signaling may be a random access preamble, and the at least one transmission parameter may include a target SNR, a backoff time, and/or a power ramp. The random access preamble may then be sent based on a target SNR value, a power ramp value, and/or a 0 backoff time value for the particular UE class. In another aspect, a message for system access may be sent based on a power control correction received in a random access response for the random access preamble. co z a) Cl) (D- a) 0 cu of _n a) U) / > _ a) L -0 0 ~ 0 - < < M_ < 0 z z E (1) C ) a u E 0) o - C) -) - T- 8 CD ) E i E u _0 ) C/ / -~ 00 ) -~CL -0a - Z Z a E a) ~ 0 0) 0 |
