Embodiment Construction

[0027] Hereinafter, embodiments of the present invention will be described based on the drawings.

[0028] In the following embodiments, a wireless communication device for realizing PDCP and / or RLC parallel processing is disclosed. To summarize the embodiments described later, it is as follows: in order to realize parallel processing in the RLC layer for the bearers transmitted in the same base station, on the one hand, multiple RLC entities are configured; on the other hand, in order to avoid redundant MAC processing, the Multiple RLC entities set one MAC entity.

[0029] First, refer to image 3 A wireless communication system according to an embodiment of the present invention will be described. image 3 It is a schematic diagram showing a radio communication system according to an embodiment of the present invention.

[0030] Such as image 3 As shown, a wireless communication system 10 has a user equipment (UE) 101 and a base station (gNB) 102 (hereinafter collective...

Abstract

Disclosed is a technique for implementing efficient parallel processing in a PDCP / RLC layer. An embodiment of the present invention relates to a wireless communication device comprising a PDCP processing unit which performs processing in a PDCP layer, a RLC processing unit which performs processing in an RLC layer, and a MAC processing unit which performs processing in a MAC layer. The RLC processing unit includes a plurality of RLC entities, and the MAC processing unit includes a single MAC entity.

Description

technical field [0001] The present invention relates to wireless communication devices. Background technique [0002] In 3GPP (3rd Generation Partnership Project), the 5th generation (5G ) system or NR (New Radio Access Technology). In the 5G system or the NR system, requirements for realizing a peak rate of 20 Gbps downlink and 10 Gbps uplink are stipulated (3GPP TR38.913 V13.0.0). [0003] For the high-speed communication speed of the physical (PHY) layer, there is a process in the PDCP (Packet Data Convergence Protocol) and / or RLC (Radio Link Control) layer that cannot follow, and the higher layer The possibility of becoming a bottleneck and not being able to achieve the peak rate. Therefore, parallelization of processing in the PDCP and / or RLC layer is being considered in order to cope with the increase in the communication speed of the PHY layer.
