Embodiment 1

[0083] figure 2 It is a schematic diagram according to Embodiment 1 of the present invention, described as follows:

[0084] There are three logical channels RB1, RB2, and RB3, the priorities of which are lowered in turn, and the PBR configurations are X, Y, and Z respectively. In a certain TTI, the corresponding Bj (j is equal to 1, 2, and 3) are DATA1, DATA2, and DATA3 respectively.

[0085] There are three component carriers scheduled for uplink transmission, and the resources authorized in a certain TTI are U, V, and W respectively.

[0086] According to the principle of adapting the Quality of Service (QoS) requirements of the logical channel according to the radio resource conditions of the component carrier, or according to the principle that the priority order of the preset component carrier corresponds to the priority order of the logical channel, The three logical channels select corresponding appropriate component carriers in descending order of priority, and the...

Embodiment 2

[0101] image 3 A schematic diagram according to Embodiment 2 of the present invention is shown, which is described as follows:

[0102] There are three logical channels RB1, RB2, and RB3, the priorities of which are lowered in turn, and the PBR configurations are X, Y, and Z respectively. In a certain TTI, the corresponding Bj (j is equal to 1, 2, and 3) are DATA1, DATA2, and DATA3 respectively.

[0103] There are three component carriers scheduled for uplink transmission, and the resources authorized in a certain TTI are U, V, and W respectively.

[0104] The sum of the resources on all component carriers is used as the total resource pool, and all logical channels are allocated resources in descending order of priority until the resources required by their PBR are met. In the figure, it is marked as operation. Therefore, the resource allocated to RB1 is X; the resource allocated to RB2 is Y; the resource allocated to RB3 is Z.

[0105] After the above steps, the Bj of ...

Embodiment 3

[0119] Figure 4 A schematic diagram according to Embodiment 3 of the present invention is shown, which is described as follows:

[0120] This example illustrates the processing procedure in the case that the resource on the component carrier selected according to the adaptation principle of the logical channel and the component carrier cannot meet the resources required by the PBR of the high-priority logical channel.

[0121] There are two logical channels RB1 and RB2, the priorities of which are lower in turn, and the PBR configurations are X and Y respectively. In a certain TTI, the corresponding Bj (j is equal to 1 and 2 respectively) are DATA1 and DATA2 respectively.

[0122] There are two component carriers scheduled for uplink transmission, and the resources authorized in a certain TTI are U and V respectively.

[0123] According to the principle of adapting the quality of service (QoS) requirements of the logical channel according to the radio resource conditions of...

Abstract

The invention discloses a method for processing priority. The method comprises the following step: allocating all resources on a component carrier to all logic channels according to the descending order of priorities, wherein, all resources contains necessary resources for meeting the need of prioritized bit rate (PBR) of all the logic channels. According to the invention, each component carrier scheduled to uplink transmission generates a media access control protocol data unit (MAC PDU) for the uplink transmission respectively.

Description

technical field [0001] The present invention relates to the communication field, in particular to a priority processing method. Background technique [0002] The Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial Radio Access Network, referred to as E-UTRAN) of the third-generation mobile communication Long Term Evolution (referred to as LTE) system is composed of base stations eNB, so it can also be called The radio interface Media Access Control (MAC) protocol layer of the base station eNB) has a scheduling / priority handling (Scheduling / Priority handling) entity, wherein the scheduling supports dynamic scheduling (Dynamic scheduling) and semi-persistent scheduling (Or called semi-persistent scheduling) (Semi-persistent Scheduling). [0003] Scheduling is used to allocate physical resources for downlink / uplink shared channels, and downlink or uplink scheduling functions are performed by different schedulers (Schedulers). In order to share re...
