Method and device for detecting uplink synchronization signal in each step in wireless access system supporting high frequency band
First Claim
1. A method for detecting a Random Access Channel (RACH) signal by a base station in a wireless access system supporting a high frequency band, the method comprising:
- allocating cyclic shift values used in the base station;
configuring a received signal vector for signals transmitted on a RACH;
deriving cyclic shift candidates whose correlation value between the received signal vector and a first detection filter is equal to or larger than a reference value, wherein the first detection filter corresponds to a filter on which a single effective channel is assumed; and
detecting a RACH signal using a second detection filter, corresponding to a filter on which multiple effective channels are assumed, within the cyclic shift candidates,wherein the first detection filter and the second detection filter are configured based on the cyclic shift values.

Abstract
The present invention provides a method for detecting an uplink synchronization signal in a wireless access system supporting a high frequency band, a method for designing a detection filter for the same, and devices for supporting the methods. A method by which a base station detects a random access channel (RACH) signal in a wireless access system supporting a high frequency band, according to one embodiment of the present invention, comprises the steps of: allocating a cyclic shift value used in the base station; configuring a reception signal vector for signals transmitted through the RACH; deriving a cyclic shift candidate greater than or equal to a reference value from the reception signal vector by using a first detection filter; and detecting the RACH signal from the cyclic shift candidate by using a second detection filter, wherein the first detection filter and the second detection filter can be set on the basis of the cyclic shift value.
