specific Embodiment 1

[0044] Such as figure 2 As shown, the base station selects two activated component carriers for the user equipment and schedules the physical uplink shared channel of the user equipment in a subframe bundling manner to transmit the same data. The frequency resource allocated by one component carrier is one resource block, the frequency resource allocated by the other component carrier is one resource block, and the modulation mode is quadrature phase shift keying. The user equipment simultaneously sends data on resource blocks allocated in each subframe.

specific Embodiment 2

[0045] Such as image 3 As shown, the base station selects 3 activated component carriers for the user equipment and schedules the physical uplink shared channel of the user equipment in a subframe bundling manner to transmit the same data. The frequency resources allocated by the three component carriers are all one resource block, and the modulation methods are all quadrature phase shift keying. The user equipment simultaneously sends data on resource blocks allocated in each subframe.

specific Embodiment 3

[0046] Such as Figure 4 As shown, the base station selects 4 activated component carriers for the user equipment and schedules the physical uplink shared channel of the user equipment in a subframe bundling manner to transmit the same data. The frequency resources allocated by these 4 component carriers are all one resource block, but the user equipment only has 3 component carriers in each subframe of the 4 bundled subframes to transmit at the same time, and each subframe in each of the 4 bundled subframes The component carrier is forbidden to transmit once in turn (it can also be forbidden to transmit once in a non-rotational manner), and the modulation method is quadrature phase shift keying.

Abstract

The invention discloses a method and system for dispatching a physical uplink shared channel (PUSCH). The method includes configuring N activated uplink component carriers for user equipment (UE), and dispatching a PUSCH of the UE in a mode of uplink carrier aggregation and subframe bundling, wherein N is an integer larger than 0. The method and the system can simultaneously employ uplink carrier aggregation and subframe bundling to carry out PUSCH transmission, and keep or even improve system performance.

Description

technical field [0001] The present invention relates to an advanced Long Term Evolution (LTE-Advanced for short) mobile communication system, in particular to a scheduling method and system for a physical uplink shared channel, and an uplink data transmission method and system. Background technique [0002] According to Section 8.6.1 of the 3GPP TS 36.213 V10.1.0 protocol of the 3rd Generation Partnership Project (3GPP for short), when a long-term evolution (LTE) base station schedules a user equipment ( When the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) is referred to as UE), the UE will continuously use 4 subframes to transmit uplink data in a subframe bundling manner, and the modulation method is quadrature phase shift keying (QPSK for short). , the allocated resources are 1 resource block (abbreviated as RB) or 2 RBs or 3 RBs. According to section 5.5 of 3GPP TS 36.300 V10.3.0, the base station can schedule the physical uplink shared channel...
