Problems solved by technology

[0003] However, since the duration of a radio frame in S-UMTS is extended to 2N×10ms, the transmission time interval (Transmission Time Interval, TTI for short) is also extended to 2N times of TTI in UMTS, so that the transmission system in S-UMTS broadcasts The period required for the message increases, and the time required for the user equipment (User Equipment, referred to as: UE) to obtain the system information block (referred to as: SIB) sent by the base station increases to 2N times the time required in UMTS, which causes the UE to read The time for obtaining the SIB is prolonged, and the time for accessing the network is prolonged, which affects the user experience and the success rate of service initiation

Abstract

Embodiments of the invention provide block transmission method and apparatus of system information, wherein, the method comprises the following steps: user equipment UE receives a broadcast control channel BCCH sent from a base station; the BCCH acquires a system information block SIB of a first part sent by the base station; the DCCH acquires SIB of a second part sent from the base station, wherein, the sum of the SIB of the first part and the SIB of the second part is integrated system broadcast information; DCCH acquires SIB of the second part sent from the base station. The system information block is transmitted by BCCH and DCCH respectively, thereby minimizing transmission time of SIB and improving transmission efficiency of SIB, minimizing time for UE to read SIB, and reducing time for accessing network, and improving user experience and improving success rate of service initiation.

Description

technical field [0001] The present invention relates to communication technology, in particular to a system information block transmission method and device. Background technique [0002] At present, the bandwidth of the Universal Mobile Telecommunication System (UMTS for short) is fixed at 5MHz. In order to apply to different frequency band bandwidths, a scalable Universal Mobile Telecommunication System (Scalable Universal Mobile Telecommunication System, short for S -UMTS), that is, narrowband UMTS, whose bandwidth is 5MHz lower than the bandwidth of standard UMTS, that is, the bandwidth of S-UMTS is determined according to the scaling factor, where the scaling factor is 2N, N is an integer greater than or equal to 1, and S- The bandwidth of UMTS is 1 / (2N) of the standard bandwidth. At the same time, in order to ensure that S-UMTS and UMTS have the same power spectral density, it is necessary to expand the time slots in S-UMTS. For a radio frame with a duration of 10ms ...
