US 2018/0294943 A1 · HARQ OPERATION WHEN TDD CELL AND FDD CELL ARE INCLUDED IN CARRIER AGGREGATION

Abstract

One disclosure of the present specification provides a method for operating a HARQ from user equipment (UE). The method comprises the steps of: the UE receiving downlink data from each cell, when at least one TDD-based cell and at least one FDD based cell are established according to carrier aggregation (CA), a specific TDD-based cell is established as a primary cell of the carrier aggregation (CA), and the at least one FDD-based cell is established as a secondary cell of the carrier aggregation (CA); the UE confirming a PUCCH format to be used for transmitting a HARQ ACK/NACK for the downlink data; and the UE determining the number of bits for transmitting the HARQ ACK/NACK when use of the specific PUCCH format for transmitting the HARQ ACK/NACK is confirmed.

Dependent claims

A method for performing a hybrid automatic retransmit request (HARQ) operation, the method performed by a user equipment (UE) and comprising:

determining a number of HARQ ACK/NACK bits to be transmitted using a physical uplink control channel (PUCCH) format;
and
wherein the UE is configured with at least one time division duplex (TDD)-based cell and at least one frequency division duplex (FDD)-based cell,
wherein the at least one TDD-based cell is configured as a primary cell,
wherein the at least one FDD-based cell is configured as a secondary cell;
wherein a maximum number of cells configured for the UE is limited such that the number of HARQ ACK/NACK bits does not exceed a maximum number of bits allowed in the PUCCH format if an uplink-downlink (UL-DL) configuration of the at least one TDD-based cell corresponding to the primary cell corresponds to one of UL-DL configurations 2, 3 and 4 and if the at least one FDD-based cell is configured as the secondary cell.
