Abstract
A communication technique for converging a 5G communication system, which is provided to support a higher data transmission rate beyond a 4G system with an IoT technology, and a system therefor applied to intelligent services (e.g., smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security and safety related service, or the like) based on the 5G communication technology and the IoT related technology by re-establishing a PDCP entity for a header compression protocol and activating uplink semi-persistent scheduling.
Claims28
A method by a terminal in a wireless communication system, the method comprising:
- receiving, from a base station, a periodicity of an uplink grant for configuring an uplink transmission and information on resources in time domain being allocated to the uplink grant on radio resource control (RRC) signaling;
- identifying time to initialize the uplink grant based on the information on the resources in time domain;
- initializing the uplink grant to start in the determined time;
- and
- transmitting data to the base station according to the uplink grant.
A method by a base station in a wireless communication system, the method comprising:
- transmitting, to a terminal, a periodicity of an uplink grant for configuring an uplink transmission and information on resources in time domain being allocated to the uplink grant on radio resource control (RRC) signaling;
- and
- receiving, from the terminal, data according to the uplink grant,
- wherein time to initialize the uplink grant is identified based on the information on the resources in time domain, and the uplink grant is initialized to start in the determined time.
A terminal in a wireless communication system, the terminal comprising:
- a transceiver;
- and
- a controller coupled with the transceiver and configured to:
