Problems solved by technology

[0005] The CB resource allocation method in the prior art may cause a waste of CB resources. For example, when no UE sends uplink data or when multiple UEs send at the same time and cause conflicts, the utilization rate of CB resources will be low.

Embodiment 1

[0031] see figure 1 , this embodiment provides a method for scheduling requests, including:

[0032] 101: Configure a first shared resource for multiple terminal devices, where the first shared resource is used by the terminal device to send an SR, and send first information to the multiple terminal devices, where the first information is used to notify the terminal device of the first Share resource;

[0033] 102: Receive an SR from the first shared resource;

[0034] 103: Allocate a second shared resource for uplink data to the multiple terminal devices, or allocate a dedicated resource for uplink data to at least one terminal device among the multiple terminal devices.

[0035] The above method is mainly applied to a device for allocating scheduling request resources and uplink data resources to terminal equipment, usually a network side equipment, such as eNB in ​​LTE, Relay (relay station), UMTS (Universal Mobile Telecommunications System, universal mobile communication...

Embodiment 2

[0038] see figure 2 , this embodiment provides a method for scheduling requests, including:

[0039] 201: The current terminal device receives the first information sent by the network side device, the first information is used to notify the first shared resource, the first shared resource is used for the terminal device to send SR, and the network side device configures for multiple terminal devices , and the multiple terminal devices include the current terminal device;

[0040] 202: Send an SR to the network side device on the first shared resource;

[0041] 203: After the network side device allocates a second shared resource for uplink data to the above-mentioned multiple terminal devices, or allocates a dedicated resource for uplink data to the current terminal device, send an uplink resource on the second shared resource or dedicated resource. data to the network side device.

[0042] The foregoing terminal device is a device on the user side, including but not limi...

Embodiment 3

[0046] see image 3 , this embodiment provides a scheduling request method, which is applied to the scenario where the eNB neither assigns an identifier to the shared resource used for the scheduling request nor assigns an index number to the UE, specifically including:

[0047]301: The eNB configures a first shared resource for scheduling requests for multiple UEs, and sends first information to the multiple UEs, where the first information is used to notify the UEs of the first shared resource.

[0048] Wherein, the eNB may determine according to at least one of factors such as QoS (Quality of Service) requirements of services established by each UE, service characteristics, UE location or channel quality, quantity of SR resources, and eNB strategy. Which UEs share an SR resource. The services established by the UE include but are not limited to: WWW (World Wide Web, World Wide Web) services, FTP (File Transfer Protocol, file transfer protocol) services, SMS (Short Messagin...

Abstract

The invention discloses a schedule requesting method, network side equipment, terminal equipment and a system and belongs to the technical field of communication. The method comprises the steps that a first sharing resource for SR is configured, and first information messages are sent to a large amount of terminal equipment; the SR on the first sharing resource is received; and a second sharing resource of uplink data is distributed for the terminal equipment, or a special resource of the uplink data is distributed for one piece of the terminal equipment. The network side equipment comprises a configuration module, a receiving module and a distributing module. The terminal equipment comprises a receiving module, a requesting module and a sending module. The system comprises the network side equipment and first terminal equipment. Uplink data resource waste is avoided, the using rate of the uplink data resources is improved, and the sending success rate of the uplink data is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to scheduling request technology. Background technique [0002] LTE-A (Long Term Evolution-Advance, the follow-up evolution of long-term evolution) technology is a further evolution of LTE (Long Term Evolution, long-term evolution). On the basis of LTE, it can further increase data rate, reduce delay, and improve coverage, etc. . Among them, in order to reduce the transmission delay of uplink data, a CB (Contention Based, contention-based) uplink authorization technology for uplink data transmission is proposed in LTE-A. This technology is different from the traditional UE (User Equipment, user equipment) The scheduling process is different when the request is made. It is the way that the eNB (evolved Node B, evolved base station) actively allocates resources for scheduling. [0003] The traditional scheduling process is as follows: UE sends SR (Scheduling Request, ...
