US 10,945,304 B2 · Apparatus and method of transmitting/receiving signals in mobile communication system supporting carriers

Abstract

The disclosure relates to methods and systems for converging a 5th-Generation (5G) communication system with technology for Internet of Things (IoT). The disclosure is applicable to intelligent services based on 5G communication and IoT-related technologies. A method for configuring a connection by a terminal is provided, which includes receiving a radio resource control (RRC) message from a base station, determining whether semi-persistent scheduling (SPS) and transmission time interval (TTI) bundling are configured based on the RRC message, determining whether dual connectivity is configured, if the SPS and the TTI bundling are configured, determining whether the TTI bundling is configured for master cell group (MCG) and the SPS is configured for secondary cell group (SCG), if the dual connectivity is configured, and configuring an RRC connection based on the RRC message, if the TTI bundling is configured for the MCG and the SPS is configured for the SCG.

Dependent claims

A method performed by a terminal in a wireless communication system, the method comprising:

determining that a downlink transmission is indicated through a physical downlink control channel (PDCCH) for a subframe, or a downlink assignment is configured through the PDCCH for the subframe, wherein the subframe with the PDCCH is included in an active time, and the subframe with the PDCCH is not part of a configured measurement gap;
and
starting a hybrid automatic repeat request (HARQ) round trip time (RTT) timer, based on the determining that the downlink transmission is indicated through the PDCCH for the subframe, or the downlink assignment is configured through the PDCCH for the subframe,
wherein the HARQ RTT timer is set based on time division duplex (TDD) configuration information associated with a primary cell in a cell group (CG), in case that the primary cell in the CG is associated with a TDD, and
wherein the primary cell in the CG is configured with a resource for a physical uplink control channel (PUCCH).
