Method and apparatus for transmission or reception of data in communication system

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method and apparatus according to an embodiment may allow a terminal or a base station to configure parameters for supporting limited buffer rate matching (LBRM) by using higher layer signaling or enable a suitable configuration to be made in a case of not configuring parameters for supporting the LBRM using the higher layer signaling.

Data transmitting method, data receiving method, terminal device, and network device

A data transmitting method, a data receiving method, a terminal device, and a network device are provided. The method includes: determining, by a terminal device, a target resource based on a time index and/or configuration information; and transmitting, by the terminal device, data to a network device on the target resource. The terminal device can control resource granularity of the target resource to meet transmission requirements of the terminal device, and can further avoid an actual data transmission process from occurring only on a same frequency domain resource and can further improve the frequency diversity gain in the non-slot transmission. In addition, randomness of interference can be enhanced as much as possible to avoid a same user from always or frequently being in conflict, so when a DMRS of the terminal device conflicts with that of other terminals, performance of user identification can be effectively improved.

Signaling radio bearer type 3 (SRB3) and secondary cell group (SCG) failure handling

A user equipment (UE) can include processing circuitry configuring the UE for Dual Connectivity (DC) with a Master Node-B (MN) and a Secondary Node-B (SN). The processing circuitry is to decode connection reconfiguration information received from the MN. The connection reconfiguration information includes signaling radio bearer type 3 (SRB3) configuration information. The SRB3 configuration information originating from the SN and configuring a SRB3, where the SRB3 is for direct communication between the UE and the SN.
