US 10,873,979 B2 · User terminal and radio communication method

Abstract

The present invention is designed to reduce the latency due to collisions in UL transmission when contention-based UL data transmission is employed. A user terminal communicates using a second transmission time interval (TTI), having a shorter TTI duration than a first TTI, and this user terminal has a transmission section that transmits multiple UL data without a UL grant from a radio base station, and a control section that controls allocation of the multiple UL data individually, and the control section applies frequency hopping to allocate the multiple UL data to resources of different second TTIs.

Claims4

Dependent claims

A terminal that communicates using a shorter time interval than a subframe, comprising:

a transmission section that transmits multiple UL data without a UL grant from a radio base station;
and
a control section that controls allocation of the multiple UL data,
wherein the control section allocates the multiple UL data to resources of different time intervals by applying frequency hopping.
