Problems solved by technology

However, the inventors of the present application found in the process of studying the coverage enhancement of the narrowband Internet of Things system that in the narrowband LTE communication system, due to the small available bandwidth in the frequency domain, one transmission block often occupies multiple subframes continuously
If the existing repetition method is used, the time span is too long, which is not conducive to fast merging and decoding at the receiving end
At the same time, since the wireless channel is a time-varying channel, the longer the time span, the greater the change of the wireless channel, which will also reduce the performance of data merging

Embodiment 1

[0097] Embodiment 1. A data sending method, such as image 3 shown, including:

[0098] S110. Select part or all of the bits from the data buffer area of ​​the transmission block to form the kth subsequence of the transmission block, forming N subsequences in total; where 1≤k≤N, N represents the number of all subsequences;

[0099] S120. Repeat the N subsequences of the transmission block for T times, perform digital baseband modulation, and then transmit; wherein, T is a positive integer, and the sum of the repetition times of the N subsequences, that is, N*T, is not less than The preset number of repetitions R. where R is a positive integer.

[0100] In this embodiment, the sending may, but is not limited to, refer to sending to the next processing unit, or may refer to sending to the peer device directly or after subsequent processing.

[0101] In this embodiment, the repetition T times means that there are T subsequences in the formed transmission block, which means tha...

Embodiment 2

[0247] Embodiment 2. A data sending device, such as Figure 11 shown, including:

[0248] A subsequence composition module 31, configured to select some or all bits from the data buffer area of ​​the transmission block to form the kth subsequence of the transmission block, and form N subsequences in total; wherein, 1≤k≤N;

[0249] The sending module 32 is used to repeat the N subsequences T times, and perform digital baseband modulation before sending; wherein, T is a positive integer, and the sum N*T of the repetition times of the N subsequences is not less than the previous The set number of repetitions R; where R is a positive integer.

[0250] Wherein, the operation of repeating the subsequence and the operation of digital baseband modulation by the sending module 32 can be performed in no particular order, and any operation can be performed first, and then another operation can be performed.

[0251] Optionally, the sending module is further configured to map the N subs...

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a data sending method and device. Background technique [0002] MTC (Machine Type Communication, Machine Type Communication) UE (User Equipment, User Equipment or Terminal), also known as M2M (Machine to Machine, Machine to Machine) user communication equipment, is currently the main application form of the Internet of Things. In the 3GPP (3rd Generation Partnership Project, third generation partnership project) technical report TR45.820V200, several technologies suitable for C-IOT (Cellular Internet of Things, cellular Internet of Things) are disclosed, among which, NB-LTE ( Narrowband Long-Term Evolution, narrowband long-term evolution) technology is the most eye-catching. The system bandwidth of the system is 200kHz, which is the same as the channel bandwidth of the GSM (Global system for Mobile Communication) system, which brings great convenience for the NB-LTE...
