Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a bearer parameter configuration method for a separated architecture base station and a wireless communication system. Background Art

[0002] Compared with 4G networks, 5G wireless network base stations introduce a design architecture that separates the control plane and the user plane, such as Figure 1 As shown, the base station user plane entity CU-UP supports SDAP layer and PDCP layer protocols, the base station control plane entity CU-CP supports RRC layer protocols, and the base station separation entity DU supports physical layer, MAC layer and RLC layer protocols. The E1 interface is used for communication between CU-CP and CU-UP, the F1-C interface is used for communication between CU-CP and DU, and the F1-U interface is used for communication between CU-UP and DU.

[0003] In some services that are sensitive to both latency and bandwidth, such as extended reality services, 3GPP SA2 defines new parameter PDU sets, each of which contains one or more PDUs. At the same time, it defines new QOS parameter configurations for PDU sets to support QoS processing based on PDU sets in NG-RAN.

[0004] In the current split architecture base station, when the base station control plane entity configures the relevant low-latency parameters for the base station user plane entity, there are still the following problems: 1) The base station user plane entity cannot determine the uplink jitter; 2) When processing packet loss, the traditional packet loss strategy uses PDU as the granularity to set packet loss, and lacks the definition of packet loss for PDU sets in the uplink / downlink direction; and in the congested state, due to the different importance of different PDU sets, discarding all PDU sets in a QOS flow will cause the throughput of the base station user plane entity for this type of service to decrease; 3) In order to assist the cache reporting of the MAC layer, the traditional PDCP layer needs to support statistics on the size of PDCP data packets and indicate them to the lower layers such as RLC or MAC layer, but for time-sensitive communication services, data packets may be discarded after a certain period of time, and the data packets counted by PDCP will make the cache calculated by the MAC layer too large, resulting in resource waste. Based on the above reasons, the current 3GPP Rel-18 5G split architecture protocol still has defects in processing time-sensitive communication services such as extended reality, and needs to be enhanced in new ways to meet the needs of network deployment and optimization.

[0005] To address the above-mentioned problems, no effective solution has been proposed yet. Summary of the invention

[0006] The embodiments of the present application provide a bearer parameter configuration method for a separated architecture base station and a wireless communication system, so as to at least solve the technical problem that the existing protocol cannot meet the requirements when the separated architecture base station processes time-sensitive communication services such as extended reality.
