Embodiment Construction

[0038] In the embodiment of the present invention, in the multi-carrier aggregation system, carrier resources are configured for the terminal according to the set scheduling principle, and corresponding time-frequency resources are allocated on the configured carrier resources, and the carrier resources and the time-frequency resources are used as Dedicated scheduling request resources;

[0039] Notifying the terminal of the carrier resource and / or the time-frequency resource.

[0040] see figure 1 As shown, the method of the embodiment of the present invention includes the following steps:

[0041] Step 101: In the multi-carrier aggregation system, configure carrier resources for the terminal according to the set scheduling principle, and allocate corresponding time-frequency resources on the configured carrier resources, and use the carrier resources and / or the time-frequency resources as Dedicated scheduling requests resources.

[0042] Here, the selection of carrier res...

Abstract

The invention discloses a special scheduling request resource allocation method and a special scheduling request resource allocation device. The method comprises the following steps of: in a multi-carrier aggregation system, determining that a terminal transmits carrier resources available for special scheduling according to set scheduling rules, and allocating the carrier resources of special scheduling requests for UE on selected carriers according to the set rules, wherein the carrier resources comprise the quantity and numbers of the carriers; and informing the terminal of the allocated carriers and available time-frequency resources on each carrier so as to realize the configuration of the time-domain and frequency-domain resources of the special scheduling requests for the terminal in the multi-carrier aggregation system.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for allocating dedicated scheduling request resources. Background technique [0002] The long-term evolution (LTE) / advanced long-term evolution (LTE-A) system is a communication system based on scheduling, that is, if there is data to be sent in the transmission buffer of the terminal (UE), then the UE needs to send a buffer status to the base station first The report (buffer status report, BSR) notifies the base station of the data information to be sent in the current sending buffer of the UE. After receiving the BSR sent by the UE, the base station allocates corresponding uplink shared channel (UL-SCH) resources for the UE according to the amount of data to be sent by the UE and the type of service, and notifies the UE to send on the allocated UL-SCH resources. data. [0003] The UE also needs to use the uplink shared channel (UL-SCH) res...
