BACKGROUND

1. Field

The present disclosure relates to method and apparatus for implementing wireless protocol configurable according to services and devices.

2. Description of Related Art

In order to meet the demand for wireless data traffic soring since the 4th generation (4G) communication system came to the market, there are ongoing efforts to develop enhanced 5th generation (5G) communication systems or pre-5G communication systems. For the reasons, the 5G communication system or pre-5G communication system is called the beyond 4G network communication system or post LTE system.

For higher data transmit rates, 5G communication systems are considered to be implemented on ultra-high frequency bands (mmWave), such as, e.g., 60 GHz. To mitigate pathloss on the ultra high frequency band and increase the reach of radio waves, the following techniques are taken into account for the 5G communication system: beamforming, massive multi-input multi-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beamforming, and large-scale antenna.

Also being developed are various technologies for the 5G communication system to have an enhanced network, such as evolved or advanced small cell, cloud radio access network (cloud RAN), ultra-dense network, device-to-device (D2D) communication, wireless backhaul, moving network, cooperative communication, coordinated multi-point (CoMP), and interference cancellation.

There are also other various schemes under development for the 5G system including, e.g., hybrid FSK and QAM modulation (FQAM) and sliding window superposition coding (SWSC), which are advanced coding modulation (ACM) schemes, and filter bank multi-carrier (FBMC), non-orthogonal multiple access (NOMA) and sparse code multiple access (SCMA), which are advanced access schemes.

The advent of brand-new services and devices leads to increased demand for mobile communication systems for supporting massive connectivity, lower latency, better reliability, and an ultra-high data rate. It is a most challenging issue to support various requirements for a diversity of types of services and devices in 5G mobile communication systems. It should be noted that all the requirements are not necessary for each service and/or each device. Some services and/or some devices may require only lower latency whereas the others may require an ultra-high data rate as well as tolerable latency.

SUMMARY

In 4G wireless protocol design (e.g., LTE rel-8 system), wireless protocol design has been optimized for voice and mobile data services. However, the LTE baseline may be too inflexible to encompass other new types of services and devices (e.g., low-cost, energy-efficient IoT devices) with different requirements. Thus, there may be a need for a new wireless protocol design capable of efficiently supporting various new types of services and devices, but rather than upgrading the LTE-based wireless protocols in 5G radio protocol design.

In 5G mobile wireless communication protocol design for supporting various services and devices, the same functionality may be supported in various ways specific to the services and/or devices. For example, random access functionality for uplink data transmission should be very reliable and fast to support ultra-reliable and low latency (URLL) services. To achieve this, noncollision-based random access with a reduced number of message exchanges may be taken into account. In random access functionality for enhanced mobile broadband (eMBB) for an ultra-high data rate, the random access procedure is contention-based but may be the same as current 4G mobile communication radio design well optimized for high-data rate mobile data. Hence, 5G radio design integrated to support various devices and services with different requirements is very challenging.

Therefore, an issue that the present disclosure is to address is to provide a wireless protocol capable of efficiently supporting various devices and services.
