Problems solved by technology

The disadvantage of this method is that once the network indicates to use a header with a large length field, then this subheader needs to be used regardless of the size of the MAC SDU
This results in unnecessary overhead in each MAC PDU for shorter sized MAC SDUs

Embodiment approach

[0032] In the first embodiment, the sending node 101a and the receiving node 101b send and receive protocol data units (PDUs) as follows: In this embodiment (eg Figure 3a and Figure 3b depicted), the network 100 signals to the node 101 during DRB creation or connection establishment if support for large MAC SDUs (or extension of the length field in the MAC subheader) is required. A signaling parameter in a Radio Resource Control (RRC) signaling message sent by the network 100 indicates whether a large MAC SDU (or an extension of the length field in the MAC subheader) is configured / supported. The RRC signaling message is an RRC connection reconfiguration message. In various embodiments, the signaling parameters are indicated in the RRC signaling message independently for each data radio bearer, or they apply to all data radio bearers. The signaling parameter is a bit value, where a value of "1" indicates that a large MAC SDU (or an extension of the length field in the MAC s...

Abstract

The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A method and system for managing data transmission in a communication network is provided. During Data Resource Bearer (DRB) creation, network signals to a transmitting node, the data transfer requirement. The network uses a signaling parameter to indicate a large data transfer requirement. Based on the data transfer requirement information collected from the network, the transmitting node determines the type of data format that needs to be used for the data transmission. If the network signals large data transfer requirement, then the transmitting node selects a Subheader format in which the length field of the data format suits the large data transfer requirement. Further, data communication is initiated using the selected Subheader format.

Description

technical field [0001] Embodiments herein relate to wireless communication networks, and more particularly, to sending and receiving protocol data units between a user equipment (UE) and a base station (BS) in a wireless communication network. Background technique [0002] In order to meet the demand for wireless data communication traffic that has increased since the deployment of 4G (fourth generation) communication systems, efforts have been made to develop improved 5G (fifth generation) or pre-5G communication systems. Therefore, 5G or pre-5G communication system is also called "super 4G network" or "post-LTE system". [0003] 5G communication systems are considered to be implemented in higher frequency (millimeter wave) bands, such as the 60GHz band, in order to achieve higher data rates. In order to reduce the propagation loss of radio waves and increase the transmission distance, beamforming, massive multiple-input multiple-output (MIMO), full-dimensional MIMO (FD-MI...
