Various embodiments of the present disclosure relate to a method for transmitting and receiving data in a wireless communication system. A method by which a terminal transmits a power headroom report (PHR) in a wireless communication system, according to one embodiment of the present disclosure, can comprise the steps of: receiving signaling information including at least one indicator indicating PHR reporting for at least one cell among cells for a dual connectivity operation; and transmitting at least one PHR for the at least one cell corresponding to the at least one indicator. The at least one cell can be a primary cell (Pcell) serving the terminal and/or a primary secondary cell (PScell) serving the terminal.

Method and apparatus for transmitting and receiving data in wireless communication system

Disclosed is a 5G or pre-5G communication system for supporting a data transmission rate higher than that of a 4G communication system such as long term evolution (LTE). Disclosed is a method by which a terminal transmits a buffer status report (BSR) in a communication system, including allocating an uplink resource from a base station; comparing the number of padding bits with a value obtained by summing the size of the BSR and the size of a sub-header of the BSR; and transmitting, to the base station according to the comparison result, the BSR including information indicating the presence or absence of a field representing a buffer size for at least one logical channel group (LCG).

Disclosed are a communication technique for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system and a system therefor. The present disclosure can be applied to intelligent services (for example, smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail, security and safety-related services, and the like) on the basis of 5G communication technology and IoT-related technology. Disclosed is a method by which a terminal performs a random access, comprising: receiving, from a serving base station, a handover command including configuration information indicating a dedicated random access resource and a common random access resource determining whether to perform a random access by using at least one of the dedicated random access resource and the common random access resource according to predetermined criteria; and performing the random access on the basis of the determination result.

Method and device for performing random access procedure

Disclosed is a method by which a first terminal supports vehicle-to-everything (V2X) communication through a first data transmission, comprising the steps of: determining a wireless resource for a second data transmission of a second terminal; transmitting, to the second terminal, first data including information of the wireless resource; and receiving, by using the wireless resource, second data transmitted from the second terminal.

V2V interaction/V2IOT communication method and device

Disclosed is a 5G or pre-5G communication system to be provided for supporting a data transmission rate higher than that of a 4G communication system such as LTE. Provided is a multilink-based data transmission method by which a data transmission device connected to a plurality of links transmits data, comprising the steps of: generating link state information including information on environments of the plurality of links; receiving link configuration information including information on available links; generating a weight for the plurality of links on the basis of the link state information and the link configuration information; selecting at least one link from among the plurality of links for which the weight is generated; and transmitting data to the selected at least one link.

Method and device for transmitting data over a selected link in multilink environment

The various embodiments of the present invention disclose a system and method for multimedia broadcast multicast service (MBMS) operation, the method comprises of receiving, by a User Equipment (UE), a common notification configuration message for a Multi-Cast Control Channel (MCCH) and System Information (SI) change from a network, identifying one or more occasions where MCCH or SI change notification is to be scheduled, configuring, by the UE, a DRX sleep and wake up occasions for the UE based on the scheduling of the MCCH and the SI change notification period, monitoring for MCCH change or SI change notification on Physical Downlink Control Channel PDCCH Format 1C scrambled with M-RNTI on wakeup occasion, determining the change notification based on DCI bits pertaining to SI and/or MCCH of one or more MBMS area, and decoding indicated SI and/or MCCH on PDSCH on CAS sub-frames and/or PMCH channel of respective areas.

System and method for providing multimedia broadcast multicast service (MBMS) operation

The various embodiments of the present invention disclose a system and method for Multimedia Broadcast Multicast Service (MBMS) counting operation is described herein. A method for multimedia broadcast multicast service (MBMS) counting operation is disclosed. In an embodiment of the present application, the method comprises of receiving, by an user equipment (UE), an MBMS counting request from a wireless communication network; sending, by the UE, an MBMS counting response on a dedicated path to the network, if the UE is in connected mode; and triggering, by the UE, a random access channel (RACH) procedure for sending the MBMS counting response, if the UE is in idle mode.

System and method for multimedia broadcast multicast service (MBMS) counting operation

A method for providing a multimedia broadcast/multicast service (MBMS) to a terminal related to a vehicle by a broadcast and multicast service center (BM-SC) is provided. The method includes identifying at least one candidate service area that the terminal is predicted to pass through, and transmitting, to an MBMS-gateway (MBMS-GW), a request for configuring the radio bearer of the at least one candidate service area.
