US 10,567,120 B2 · Method and apparatus for determining number of HARQ processes in wireless communication system

Abstract

Provided are a method for determining the number of hybrid automatic repeat request (HARQ) processes in a carrier aggregated system configured with a plurality of serving cells, and an apparatus using such a method. The method receives data from a downlink subframe of a second serving cell, and transmits an ACK/NACK signal for the data from an uplink subframe of a first serving cell, wherein the first serving cell uses a first-type frame, the second serving cell uses a second-type frame, and the number of HARQ processes in the second serving cell are determined with respect to each subframe comprised in the second-type frame and on the basis of the number of downlink subframes comprised in each section comprising a set number of subframes.

Dependent claims

A method for performing hybrid automatic repeat request (HARQ) processes in a carrier aggregation system with which a plurality of serving cells including a primary cell and a secondary cell are configured, the method performed by a user equipment (UE) and comprising:

receiving a signal;
determining a number of HARQ processes of the secondary cell among the plurality of serving cells based on the signal;
and
receiving physical downlink shared channels (PDSCHs) related to the HARQ processes on the secondary cell,
wherein based on the signal informing a specific number, the UE determines the number of HARQ processes of the secondary cell as same as the specific number,
wherein based on the signal not informing the specific number, the UE determines the number of HARQ processes of the secondary cell as a predetermined value, and
wherein a bit field size of the signal informing the number of HARQ processes of the secondary cell is 4 regardless of a type of the secondary cell.
