Description

Method and equipment for reporting

Technical Field

The present invention relates to the field of wireless communications technologies, and in particular, to a method and a device for reporting.

Background

With the deployment of more and more home base stations, micro cells, relays and other local nodes, the traditional network architecture mainly based on macro base stations gradually evolves to a network architecture with more types of base stations coexisting, and provides more levels of network coverage. In order to improve the correlation performance under the multi-type base station coexistence network architecture, a network architecture for realizing cooperation/aggregation among multiple base stations through non-ideal links is provided.

Under the architecture, a part of RBs (Radio Bearer ) of a UE (User Equipment) is on an MCell (Master Cell) managed by an MeNB (Master eNB, Master base station), and the part of RBs includes a control plane SRB (Signaling Radio Bearer) and a User plane DRB (Data Radio Bearer ). While another part of the same UE is carried (including SRBs and DRBs) on a SCell (Secondary Cell) managed by the SeNB (Secondary base station).

One possible multi-layer network overlay environment is shown in fig. 1. In this scenario, multiple RBs of the UE may be respectively carried by a MeNB-controlled cell (MCell) and an SeNB-controlled cell (SCell). Wherein the RB detached to the SeNB may include a DRB and/or an SRB.

And the UE respectively transmits uplink data simultaneously through the MeNB and the SeNB, and the operation is uplink separated bearer.

In order to obtain more throughput gain for the uplink split bearer, a technique implements: defining a threshold value reported by a multi-cell BSR (Buffer Status Report), where the threshold value is calculated based on all Data volumes (including SDU (Service Data Unit)/PDU (Protocol Data Unit)) of a Packet Data Convergence Protocol (PDCP) Buffer, and when the Data volume equals or exceeds the threshold value, the UE performs special processing, such as: the multiple cells report the same BS (Buffer Status) content. When below this threshold, BSR reporting will be triggered only for network configuration CG (Cell Group).

At present, the mode of performing multi-cell BSR reporting operation by the UE may cause that the network side cannot determine whether the UE performs multi-cell BSR reporting operation according to the BSR reporting content, thereby affecting subsequent network uplink data scheduling and further affecting uplink throughput.

Optionally, the terminal may determine the target data after meeting the BSR reporting condition.

The specific content of the BSR reporting condition may refer to a 3GPP TS 36.321 protocol, which is not described herein again.

In implementation, the embodiment of the present invention may set the threshold value based on different objects, and the target data determined by the terminal is different for the threshold values set for different objects.

If the threshold is a threshold based on data of all PDUs and SDUs in a PDCP (Cell Group) entity buffer area corresponding to a separate bearer and an RLC (Radio Link Control) entity buffer area corresponding to the separate bearer or any one CG (Radio Link Control), the target data includes data of the PDCP buffer area and data of the RLC entity buffer area (Radio Link Control), the PDCP buffered data is data of the PDCP buffer area corresponding to the separate bearer, and the RLC entity buffer area data is data of all PDUs and SDUs in the RLC entity buffer area corresponding to the separate bearer or any one CG.

And if the threshold value is based on the threshold value of separating and carrying all the data of the PDUs and the data of the SDUs in the corresponding PDCP buffer area, the target data comprises the data of the PDCP buffer area, and the data of the PDCP buffer area is the data of separating and carrying all the PDUs and the data of the SDUs in the corresponding PDCP buffer area.

In implementation, based on different objects, when determining the BSR reporting mode according to the result, there are also different reporting modes. As described in detail below.

Based on an object, two reporting modes exist:

in a first reporting mode, if the data volume of the target data is not less than a set threshold value, the terminal determines the BS content to be reported, wherein the BS content to be reported comprises the sum of the data volume of a PDCP buffer corresponding to a separate bearer and the data volume of all CGs corresponding to the separate bearer or an RLC entity buffer of the CG to be reported;

And (3) reporting mode based on the object two:

There are two reporting modes based on three objects:

in the first reporting mode, if the data volume of the target data is greater than a set threshold value, the terminal determines the BS content to be reported and sends the determined BS content to all the CGs corresponding to the separated bearer, wherein the BS content to be reported comprises the sum of the data volume of the PDCP buffer corresponding to the separated bearer and the data volume of all the CGs corresponding to the separated bearer or the RLC entity buffer of the CG to be reported;

And secondly, the terminal determines the BS content to be reported and sends the determined BS content to the CG configured on the network side, wherein the BS content to be reported comprises the sum of the data volume of the PDCP buffer area corresponding to the separated load and the data volume of the RLC entity buffer area of the CG configured on the network side.

In implementation, if the data amount of the target data is equal to a set threshold, which of the two methods is specifically adopted may be specified in a protocol; or can be notified by the network side; it is also possible that the terminal selects itself and informs the network which way to use.

A second reporting mode, if the data volume of the target data is larger than a set threshold value, the terminal determines the BS content to be reported and sends the determined BS content to all the CGs corresponding to the separated bearer, wherein the BS content to be reported comprises the sum of the data volume of all the PDCP buffer areas in the LCG where the separated bearer is located and the data volume of all the CGs in the LCG where the separated bearer is located or the RLC entity buffer areas of the CGs to be reported;

And (3) reporting mode based on the object four:

Optionally, the terminal may further place information indicating that the BSR is to perform special processing in the BS content or send the information to the network side together with the BS content, so as to notify the network side whether the BSR is lower than or higher than the threshold or equal to the threshold.

Optionally, after determining the BSR reporting mode according to the comparison result, the terminal may also notify the network side of the determined BSR reporting mode, such as reporting to all CGs or reporting to some CGs.
