example 1

[0095] Example 1: Indicates that the combination number index is And satisfy M=3, s 0 1 ≤s 2 ,1≤s i ≤N, is the number of downlink resource units, where is the extended binomial coefficient, and The total number of states is Need to indicate that the overhead is bit. It should be noted, It is only the total number of resources represented when the downlink uses PRB as the granularity, but the embodiments of the present invention are not limited thereto, and are also applicable to other resource granularities. For example, when the granularity of PRB is used for uplink, the total number of resources is expressed as For another example, when using CCE as the granularity, the total number of resources is N CCE . In this embodiment, x, y, n, k, etc. are just code names, which can be replaced arbitrarily, and the emphasis is on clarifying the operations therein.

example 2

[0096] Example 2: Indicates that the combination number index is And satisfy M=3, s 0 1 ≤s 2 ,0≤s i ≤N, in is the extended binomial coefficient, and The total number of states is Need to indicate that the overhead is bit.

example 3

[0097] Example 3: Indicates that the combination number index is And satisfy M=3, s' 1 2 ≤s' 3 ,1≤s′ i ≤N′, N'=N+1,s i =s i '-1, where is the extended binomial coefficient, and The total number of states is Need to indicate that the overhead is bit.

[0098] After the receiving side receives the combination number index, for example 1 and example 2, the receiving side engraves the inverse solution s according to r i (The same reasoning is also applicable to the receiving side in Example 3 and reversely solves s according to r i ' and then get s i ), taking M=3 as an example: first select the The value of n corresponding to the maximum number of combinations in is used as the decoding s 0 The value of the number of combinations, that is, at this time s 0 =N-n 0 , and calculate the difference Next, choose to satisfy The value of n corresponding to the maximum number of combinations is used as the decoding s 1 The value of the number of combinations...

Abstract

The invention discloses an information transmission method and device, a base station and a storage medium, and relates to the technical field of communication so as to solve a problem that in the prior art, information transmission is easy to generate time delay increase. The method comprises the steps of: determining an information transmission resource; and according to a transmission resourcedetermination result, carrying out corresponding information transmission, wherein at least two transmission blocks in information are mapped into a single code word to be transmitted, or the information is transmitted by using a control channel resource.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an information transmission method, device, base station and storage medium. Background technique [0002] Currently, the 4th generation mobile communication technology (4G, the 4th Generation mobile communication technology) long-term evolution (LTE, Long-Term Evolution) / advanced long-term evolution (LTE-Advance / LTE-A, Long-Term Evolution Advance) and the fifth generation mobile Communication technology (5G, the 5th Generation mobile communication technology) is facing more and more demands. Judging from the current development trend, both 4G and 5G systems are researching features that support ultra-high reliability and ultra-low latency transmission. [0003] For the scenario where the initial transmission transmits two codewords (codeword) with spatial multiplexing, each codeword corresponds to a TB (transport block, transmission block). When both codewords ar...
