Embodiment Construction

[0024] The specific implementation manner of the method for sending system scheduling information of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] The frame length of a TDMA system defined by 3GPP is 10ms. For example, in the TD-SCDMA system, the TD-SCDMA system divides a 10ms frame into two subframes with the same structure. The duration of each subframe is 5ms, and each 5ms A subframe consists of 3 special time slots and 7 regular time slots (TS0~TS6); in these 7 regular time slots, TS0 is always used as a downlink time slot to send system broadcast information (on a single carrier frequency cells, usually do not carry services).

[0026] see figure 1 as shown, figure 1 A flow chart showing a method for sending system scheduling information in an embodiment mainly includes the following steps:

[0027] In step S101, system scheduling information is pre-processed for transmission to obtain system information...

Abstract

The invention provides a system scheduling information transmission method, which comprises the following steps of: performing transmission preprocessing on system scheduling information to obtain system information blocks suitable for channel transmission; calculating a repetition period for the transmission of the system scheduling information after a plurality of idle timeslots are set in a broadcast channel according to the number of the system information blocks, wherein the system scheduling information is not transmitted in the idle timeslots; and filling the system information blocks into the broadcast channel for transmission according to the repetition period, and communicating with other base stations by utilizing the idle timeslots. The invention also provides a system scheduling information transmission device and a base station system. By the technology, the data communication of a base station with the other base stations also can be realized in a system scheduling information transmission process, so that the complexity of a processing process for realizing a system function is lowered, the utilization rates of resources are increased, the processing capability of the base station is improved, and the construction cost of the base station is reduced.

Description

technical field [0001] The present invention relates to system scheduling information sending technology, in particular to a system scheduling information sending method, device and base station system. Background technique [0002] In the TD-SCDMA system, after the user terminal equipment (User Equipment, UE) is turned on, it searches for a cell and camps on it. After camping on a suitable cell, the UE starts to read the system scheduling information on the broadcast channel (BCH) , further, the UE can establish a connection with the base station to communicate with the base station according to the information. [0003] For the existing system scheduling information transmission method (refer to 3GPP 25.331), when the system information is transmitted on the broadcast channel, it is divided into different types of system information blocks according to the carried content. Due to the limitation of the BCH transmission block format, it is necessary to The system informatio...
