Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. According to various embodiments of the disclosure, a method performed by an electronic device may include: identifying a CHS group (CHG) event including a connected hybrid stream (CHS) event; identifying at least one subevent included in the CHS event; transmitting a data packet within a period of a first subevent among the at least one subevent; and receiving a feedback signal based on the data packet within the period of the first subevent.

Abstract: Various embodiments of the present disclosure relate to an electronic device for transmitting data and an operation method thereof ?n electronic device according to an embodiment of the present disclosure may include a communication circuit configured to support Bluetooth low energy (BLE), and at least one processor operatively connected to the communication circuit, wherein the at least one processor is configured to identify first data packets by dividing the same to correspond to the number of subevents, identify at least one first subevent and at least one second subevent in the divided subevents, update, based on an offset, the at least one first subevent and the at least one second subevent, and transmit, to an external electronic device, the first data packets included in the updated first subevent and the updated second subevent. In addition, various embodiments identified through the specification are also possible.

Abstract: A method for reporting channel state information of a terminal comprises: a step of measuring CSI-RS transmitted from a base station; and a step of reporting CSI generated on the basis of the CSI-RS measurement to the base station, wherein the CSI comprises: a PMI for indicating a precoding matrix from a codebook and an RI for indicating a rank, wherein the PMI comprises a first PMI for a beam group selected by the terminal and a second PMI which comprises a beam sub-group selection information for beams included in the beam group and phase-matching information for each antenna port polarization for the selected beam sub-group, and wherein as the rank increases, the phase-matching information may be indicated with different granularity from each other depending on whether the beam sub-groups selected from the beam group are the same or different.
