Abstract

The present invention discloses a method and device for configuring uplink scheduling request resources applied to fast scheduling. The method includes: generating 8 orthogonal codes for SR uplink scheduling request location resources of an uplink frame; Adding at least one partially orthogonal code; configuring the newly added partially orthogonal code as an SR code resource for fast scheduling. The application of the present invention can reduce the average access duration of UE fast scheduling and improve the access efficiency.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an uplink scheduling request resource configuration method and device applied to fast scheduling. Background technique [0002] The LTE (Long Term Evolution, long-term evolution system) 230 system is a wireless network that works in the 230M frequency band and is oriented to applications such as power system data collection, power distribution control, and video communication. The authorized frequency points of the power communication network are discretely distributed in the frequency band from 223.525MHz to 231.65MHz, a total of 40. The bandwidth of each authorized frequency point is 25KHz, which is called a physical sub-wait. Among them, 3 bit synchronization sub-bands, actually 37 frequency points are service sub-bands. The position of UPpts (uplink pilot time slot physical channel) on each service subband is assigned as the position of SR (uplink scheduling ...
