Problems solved by technology

In the current LTE-A system, there are relatively few PDCCHs that can be used, and neither independent PDCCHs nor simple joint coding of PDCCHs can effectively reduce the occupation of PDCCHs. Therefore, when more PDCCHs are needed for scheduling, PDCCHs are used Will be limited, which will affect the normal scheduling of data, and then affect the data transmission delay

Embodiment 1

[0042] The multi-carrier scheduling configuration message sent by the eNB to the UE indicates that the UE can be scheduled by a PDCCH command to the UE to send and receive data. The number of the carrier where the PDCCH commands of multiple carriers are located. The resource block coding method is that each carrier is coded sequentially. For the convenience of description, the carrier that the above-mentioned eNB schedules to the UE for data transmission and reception through the PDCCH command is called the first carrier, and the carrier where the PDCCH commands that schedule the multiple first carriers are located is called the second carrier. The following embodiments continue to use the same terminology.

[0043] Thereafter, the eNB sends a PDCCH order to the UE on the second carrier. In the PDCCH order, the indication information of the resource blocks that the UE can use includes the resource block start code and the number of resource blocks, so that the UE can use the ...

Embodiment 2

[0047] As a variant of Embodiment 1, the multi-carrier scheduling configuration message sent by the eNB to the UE indicates that the encoding of the multiple first carriers scheduled by the UE is continuous, and the resource block encoding mode of the first carrier is unified for the first carrier sequential encoding.

[0048] Afterwards, the eNB sends a PDCCH order to the UE on the second carrier, and the indication information of the resource blocks that the UE can use in the PDCCH order includes the start code of the resource block and the number of resource blocks, so that the UE can use the resource block on the first carrier. The resource block starts encoding and resources defined by the resource block number.

[0049] For example, the first carrier is carrier 1 and carrier 2, the second carrier is carrier 3, and the codes of RBs on carriers 1 and 2 are RB Index=0~49, that is, RB Index=0~24 on carrier 1 and RB index on carrier 2 RB Index=25~49; the PDCCH command indica...

Embodiment 3

[0052] The multi-carrier scheduling configuration message sent by the eNB to the UE indicates the number of multiple first carriers scheduled by the UE, where the resource block encoding method of the first carrier is based on the second carrier that sends the PDCCH command, and is paired according to the carrier number The carriers indicated by the number of the first carriers are sequentially coded.

[0053] According to the embodiment of the present invention, in specific implementation, all carriers configured for the UE may be scheduled by default, and the number of first carriers is equal to the number of all carriers configured for the UE.

[0054] Thereafter, the eNB sends a PDCCH order to the UE on the second carrier, and the indication information of the resource blocks available to the UE in the PDCCH order includes the resource block start code and the number of resource blocks, so that the UE can use the first resources on a carrier defined by said resource block ...

Abstract

The invention relates to a method and a device of multi-carrier scheduling. The method of the multi-carrier scheduling comprises sending multi-carrier configuration information to user equipment (UE), wherein the multi-carrier configuration information comprises the information of a plurality of carriers scheduled by physical downlink control channel (PDCCH) instructions and the resource block coding scheme information of the first carriers, sending PDCCH instructions through a second carrier, wherein the PDCCH instructions comprise the indicating information of a resource block capable of being used by the UE, and enabling the UE to schedule the resources of the first carriers according to the information of the first carrier, the resource block coding scheme and the indicating information. According to the method and the device of the multi-carrier scheduling, the scheduling of the resources of multiple carriers is achieved by effective noise bandwidth (eNB) through a PDCCH instruction, the efficiency of scheduling multiple carriers by the PDCCH is improved, the limited degree of the PDCCH is relieved, and data transmission delay is reduced.

Description

technical field [0001] The present invention relates to wireless communication technology, and more specifically, to a method and equipment for multi-carrier scheduling. Background technique [0002] In order to improve the peak rate of user equipment (User Equipment, referred to as UE), LTE-A introduces the concept of multiple carrier aggregation (Carrier Aggregation, referred to as CA). When the UE needs to aggregate multiple carriers to transmit data, the base station (Evolutional NodeB, The eNB for short) can allocate multiple serving cells / component carriers (CC for short) to the UE, and one of the CCs is used as the primary component carrier (PCC for short), and the cell where the PCC is located is also called the primary cell (Primary Cell, PCell for short), other CCs serve as Secondary Component Carriers (SCC for short), and the cell where the SCC is located is also called a Secondary Cell (SCell for short). [0003] In a heterogeneous network, in order to avoid the...
