Claim of US Patent No. 10,484,143
1. A method in a User Equipment (UE) supporting short-latency radio communications, comprising:receiving K radio signal groups, K being a positive integer greater than 1;
transmitting a single uplink signaling related to correct decoding of the received K radio signal groups, the single uplink signaling comprising HARQ-ACK information; wherein:
the K radio signal groups are received in K time windows on a same carrier, and any two time windows of the K time windows are orthogonal in the time domain;
lengths of Enhanced Transmission Time Intervals (eTTIs) corresponding to the K radio signal groups correspond to K time lengths respectively, and any two time lengths of the K time lengths are not equal;
the HARQ-ACK information indicates whether a coding block in each of the K radio signal groups is correctly decoded;
the number of radio signals in the K radio signal groups are Q1, . . . , QK respectively, the Q1, . . . , QK being positive integers respectively; and
in the K radio signal groups that are associated with the uplink signaling, an eTTI length corresponding to a radio signal group transmitted earlier is greater than an eTTI length corresponding to a radio signal group transmitted later.
