Abstract
The disclosure relates to a communication technique and a system for converging a 5G communication system with IoT technology to support a higher data rate after a 4G system. Based on 5G communication technology and IoT-related technologies, the disclosure can be applied to intelligent services (e.g., smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, security and safety related services, etc.). The disclosure provides a method and apparatus for selecting data to be transmitted when data transmission occurs simultaneously in different cells.
Claims12
A method performed by a terminal in a wireless communication system, the method comprising:
- identifying a first uplink resource associated with data to be transmitted by a lower layer of a medium access control (MAC) entity configured with a logical channel (LCH)-based prioritization operation;
- identifying whether the first uplink resource does not overlap with a second uplink resource associated with a logical channel having a priority higher than a priority of the first uplink resource, wherein the second uplink resource has not been de-prioritized;
- identifying whether a simultaneous transmission of the first uplink resource and the second uplink resource is not allowed by a configuration;
- and
- in case that the first uplink resource does not overlap with the second uplink resource and the simultaneous transmission of the first uplink resource and the second uplink resource is not allowed by the configuration, identifying the first uplink resource as a prioritized uplink resource,
- wherein the configuration is associated with a simultaneous physical uplink shared channel (PUSCH) and physical uplink control channel (PUCCH) transmission with different priorities.
A terminal in a wireless communication system, 8. the terminal comprising:
- a transceiver;
- and
- a controller configured to:
- identify a first uplink resource associated with data to be transmitted by a lower layer of a medium access control (MAC) entity configured with a logical channel (LCH)-based prioritization operation,
- identify whether the first uplink resource does not overlap with a second uplink resource associated with a logical channel having which has-a priority higher than a priority of the first uplink resource, wherein the second uplink resource has not been de-prioritized,
- identify whether a simultaneous transmission of the first uplink resource and the second uplink resource is not allowed by a configuration, and
- in case that the first uplink resource does not overlap with the second uplink resource and the simultaneous transmission of the first uplink resource and the second uplink resource is not allowed by the configuration, identify the first uplink resource as a prioritized uplink resource,
- wherein the configuration is associated with a simultaneous physical uplink shared channel (PUSCH) and physical uplink control channel (PUCCH) transmission with different priorities.
