Embodiment Construction

[0045] As mentioned in the background, in the prior art, when organizing and scheduling the system information blocks, only the system information blocks with the same repetition period are placed in one SI, and each SI is not protected from cross-border, which may lead to a Too much content in the SI cannot be sent, and the system information blocks that must be obtained cannot be obtained smoothly, which wastes memory and is easy to cause memory out of bounds due to a single system information block being too large, PER encoding failure, and cell establishment failure.

[0046] For this reason, Embodiment 1 of the present application proposes a system information transmission method, which is applied to the LTE system to solve problems in the prior art, such as figure 2 Shown, specifically include the following steps:

[0047] Step 201, respectively assigning system information blocks with large capacities to be transmitted in different system information SIs;

[0048] In ...

Abstract

The present application discloses a system information transmission method and device, including: respectively assigning system information blocks with large capacities to different system information SIs for transmission; separately assigning system information block SIB2 among small-capacity system information blocks to one SI transmission; determine the number of other small-capacity system information blocks other than the SIB2 and the repetition period of each of the other small-capacity system information blocks; if there are multiple small-capacity system information blocks, it is the small-capacity system information with the same repetition period Block allocation is transmitted in the same SI, and small-capacity system information blocks with different repetition periods are allocated for transmission in different SIs; this saves memory, prevents memory out of bounds, and avoids cell establishment failure due to memory out of bounds, PER Encoding failure problem.

Description

technical field [0001] The embodiment of the present application relates to the technical field of communications, and in particular to a system information transmission method. The embodiment of the present application also relates to a system information transmission device. Background technique [0002] The current implementation of system information is as follows: figure 1 As shown, the configuration in the database is read, and each system information block (SIB1-SIB7) is constructed, wherein no cross-border protection is performed for each system information block. When organizing and scheduling system information blocks, the system information blocks with the same repetition period are placed in one system information SI, and no cross-border protection is performed for each SI. [0003] According to the existing method of constructing system information, the following situations will occur: [0004] 1. Since the existing organizational scheduling information puts ...
