[0006] However, the existing evaluation results show that even if the TTI Bundling technology is applied, the VoIP service still cannot achieve ideal coverage due to the limitation of the maximum transmit power of the uplink
For how to further improve the coverage performance of VoIP services under the 50ms delay limit, no effective solution has been proposed yet

Embodiment 1
[0091] Assuming that the currently supported RV index number is 5, specifically {0, 1, 2, 3, 4}, all the nth (n=1, 2, 3, 4) transmission attempts of the first VoIP packet RV data is represented as:
[0092] { RV 0 n , RV 1 n , RV 2 n , RV 3 n , RV 4 n } .
[0093] Such as Figure 4 As shown, the execution of the nth (n=1, 2, 3, 4) transmission attempt of the first VoIP data packet includes:
[0094] Select the 5 RV data of the 1st transmission attempt of the 1st VoIP data packet, and map the 5 RV data to TTI 01 to TTI 05 of the 1st transmission attempt according to the order of the RV index, specifically, The RV data related to TTI 01 to TTI 05 are:
[0095] ...
Embodiment 2
[0103] Assuming that the currently supported RV index number is 4, specifically {0, 1, 2, 3}, all RV data of the nth (n=1, 2, 3, 4) transmission attempt of the first VoIP packet Expressed as:
[0104] { RV 0 n , RV 1 n , RV 2 n , RV 3 n } .
[0105] Such as Figure 5 As shown, the execution of the nth (n=1, 2, 3, 4) transmission attempt of the first VoIP data packet includes:
[0106] Select the 4 RV data of the first transmission attempt of the first VoIP data packet, and map the 4 RV data to TTI 01 to TTI 05 of the first transmission attempt according to the order of the RV index, specifically, The RV data related to TTI 01 to TTI 05 are:
[0107] { RV 0 1 ...

Abstract
The invention discloses a transmission time interval cluster transmission method and device. The method comprises the steps that a terminal determines a set A of an air interfacedelaytime limit d and common divisors, smaller than p, in common divisors of a reach period p of a data packet; elements, meeting the formula: mod(d-a, (p / a)-1)=0, in the set A are determined and form a subset B; values corresponding to the elements in the subset B in a one-to-one mode are computed according to the formula: c=(d-b) / ((p / b)-1) and form a set C; a minimum value cmin in the elements of the set C is determined, an element bcmin, corresponding to the cmin, in the subset B is determined, the bcmin is used as a continuous TTI number used in a transmission try in transmission time interval cluster transmission, and the cmin is used as loopback time; when the terminal transmits the data packet, on the basis that the continuous TTI number used in one transmission try is the bcmin and the loopback time is the cmin, redundancy version data of the date packet in each transmission try are sent.
Description
technical field [0001] The present invention relates to a long-term evolution system, in particular to a transmission time interval bundling transmission method and device. Background technique [0002] The radio access network of the Long Term Evolution (referred to as LTE) system includes: a network side (enhanced Node B, eNB) and a user equipment (UE), wherein the network side is connected to a core network or other networks, and is connected through The wireless interface communicates with the UE located in the cell served by the network side. In order to improve the uplink (UL) inter-network voice, that is, IP-based voice transmission (Voice over IP, referred to as VoIP) service coverage, the LTE physical layer introduces Transmission Time Interval Bundling (Transmission Time Interval Bundling, referred to as TTI Bundling) technology. [0003] Wherein, the transmission time interval bundling TTI Bundling refers to that the scheduler allocates radio resources exceeding...
