Abstract

Methods and apparatus are provided for repeated transmission. In one novel aspect, the RV sequence is selected from a predefined set of RV sequences for the repeated transmission. In one embodiment, the one or more RV values in the selected RV sequence are repeatedly used for the repeated transmission, by applying each RV value one by one to one block of repetitions cyclically, wherein the number of repetition in the block is determined by the repetition number and the length of the RV sequence. In another embodiment, the one or more RV values in the selected RV sequence are repeatedly used for the repeated transmission, by applying each RV value one by one to one repetition cyclically. In one embodiment, the RV value and the scrambling sequences are the same for the repetition blocks and a symbol level combination is applied.

Dependent claims

A method comprising:

obtaining a repetition configuration by a user equipment (UE) in a wireless communication system, wherein the repetition configuration configures each repetition for repeatedly transmitted information packets;
determining a repetition time interval (RTI) length for the repeatedly transmitted information;
receiving information packets from a base station, wherein the information packets are transmitted repeatedly by a repetition number, and wherein a redundancy version (RV) value is selected from a preconfigured RV sequence for each repeated transmission n, and wherein the RV sequence is repeatedly used for the repeated transmission by (a) applying each RV value to one block of repetitions such that each block of repetitions has the same RV value, wherein the number of repetition blocks is determined by the repetition number, and (b) applying each RV value one by one to each repetition blocks cyclically;
and
combining each received repetition of the information packets and decoding the information packets based on the repetition configuration.
