Problems solved by technology

If several ultra-real-time services (services with higher priority than the existing LCG) LCG are defined in the existing LCG, the differentiation degree of the original service will be affected to a certain extent
If the method of increasing the length of the LCGID in the BSR is used, on the one hand, there will be incompatibility problems, and on the other hand, the BSR will become significantly larger. For ultra-real-time services, reporting a larger BSR will inevitably bring more time delay and resources. Waste; and in the future 5G is likely to use a shorter transmission time interval (TTI, Transmission TimeInterval) to transmit BSR, increasing the BSR of LCG ID length will bring further restrictions

Embodiment 1

[0044] In this embodiment, the format of the super real-time service-specific buffer status report (hereinafter referred to as S-BSR) provided by the present invention is specifically described.

[0045] Specifically, S-BSR is divided into short S-BSR or truncated S-BSR and long S-BSR. In this embodiment, the long (Long) S-BSR is based on whether it has the support for ordinary service buffer status report Capabilities are divided into two format types, the first format and the second format. The long S-BSR in the first format only has the ability to report the status report of the super real-time service buffer, that is, it can only map the buffer data size of the logical channel group corresponding to the super real-time service; the long S-BSR in the second format also has The ability to report the super real-time service buffer status report and the ordinary service status report, that is, the ability to map the data volume of the logical channel group buffer corresponding...

Embodiment 2

[0057] In this embodiment, the report trigger condition of the super real-time service-specific buffer status report (S-BSR) provided by this embodiment is described.

[0058] Specifically, when at least one of the following events occurs, the reporting of the S-BSR is triggered:

[0059] (1) When any one of all logical channels in the super-real-time logical channel group has data to send, it will trigger the reporting of the S-BSR, and here, such an S-BSR is called a conventional S-BSR;

[0060] Specifically, when more than one logical channel group in the super real-time logical channel group has data to be sent, the long S-BSR in the first format or the long S-BSR in the second format is selected for reporting, wherein the S-BSR The specific selection of the format depends on the format configuration of the S-BSR of the user equipment and whether there is data to be sent in the common service logic channel group in the current TTI. If there is a second format in the format...

Embodiment 3

[0070] This embodiment illustrates the coexistence of common service buffer status reports and ultra-real-time service-specific buffer status reports. Specifically, in the case where the common service BSR and the super real-time service S-BSR coexist, optionally, the common service BSR and the super real-time service S-BSR are simultaneously sent in one MAC PDU, such as Figure 8 Shown, adopt the mode of described simultaneous transmission, comprise the MAC control unit of common business BSR and super real-time business S-BSR in MAC PDU, have corresponding two subheads correspondingly at the subheader of MAC simultaneously, in subheader Different BSRs are identified by the LCID value in the section, and the LCID value is configured by the base station through Radio Resource Control (RRC, Radio Resource Control) signaling; optionally, the normal service BSR and the super real-time service S- BSR, that is, in a MAC PDU, either a common service BSR or a super real-time service ...

Abstract

The invention discloses a method, a device and a system for reporting a buffer status report (BSR). The method comprises steps: user equipment receives the format configuration information of the BSR sent by a base station, wherein the BSR format configuration information comprises the format of a buffer status report specially for super real-time service (S-BSR); and when the user equipment detects the buffer status report specially for the super real-time service needs to be reported, the user equipment reports the buffer status report specially for the super real-time service in the format of the buffer status report specially for the super real-time service. According to the method, the device and the system for the reporting buffer status report, the user equipment in a connected state can report the buffer status report for the super real-time service to the base station.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a reporting method, device and system for a buffer status report. Background technique [0002] The rapid development of mobile Internet, Internet of Things and other business applications has become the main driving force to promote the development of the fifth generation mobile communication technology (5G). real-time experience and wireless broadband access anytime, anywhere. In addition, important indicators such as energy efficiency, spectrum efficiency, and peak rate also need to be considered comprehensively in the design of 5G systems. In 2013, China established the IMT-2020 (5G) promotion group to promote the development of 5G technology. According to the overall international situation, it is expected that 5G vision, key capability requirements and spectrum planning will be formed in 2015; after that, 5G standardization work will be launched, and it is planned to s...
