Problems solved by technology

[0003] However, in the prior art, none of these header information can reflect the time urgency of the requested service data to be transmitted, such as the waiting delay of the service data, and the waiting delay includes possible bandwidth request message buffering Delay, bandwidth request message transmission conflict avoidance delay and relay station processing delay, etc., may also include the waiting delay for the mobile terminal to wait for a period of time and then resend the resource allocation request message because the current bandwidth request is rejected
If the base station does not consider this information, it will allocate resources indiscriminately between requests that have been delayed by collisions and those that have not been delayed. This allocation strategy is unreasonable, and it cannot provide shorter service delays. and better system fairness
This is especially problematic in relay-based multi-hop networks due to potentially longer buffering, relaying, and propagation delays and more contention for resources

[0027] figure 2 According to a specific embodiment of the present invention, the mobile terminal M requests the base station B to allocate resources to the base station B through the relay station R, and it is a schematic diagram of a two-hop network topology. image 3 According to a specific embodiment of the present invention, the mobile terminal M sends a resource allocation request to request resources, the relay station R forwards the resource allocation request, and the base station B allocates resources for multiple mobile terminals according to the resource allocation request. The following will refer to the attached figure 2 And attached image 3 , the method of the present invention is described in detail.

[0028] The time information described in this embodiment is the average generation time of the service data to be transmitted in the mobile terminal M, the mobile terminal sends a resource allocation request including the average generation time of the service ...

[0053] In the second embodiment, the time information of the urgency information contained in the resource allocation request generated by the mobile terminal M is the average waiting delay of the service data to be transmitted, that is, from the generation of the service data to be transmitted in the mobile terminal M to the The average time interval between resource allocation requests. When base station B allocates resources to each mobile terminal under its jurisdiction, resources are allocated to each mobile terminal in sequence according to the average waiting time delay of service data to be transmitted in each mobile terminal at this time.

[0054] Image 6 According to the second embodiment of the present invention, it shows a flowchart of a system method in which a mobile terminal M sends a resource allocation request, a relay station R updates and forwards the resource allocation request, and a base station B allocates resources for multiple mobile terminals accordi...

[0078] As a modification example of the first embodiment above, considering the fact that the business data to be transmitted is divided into batches, for the same batch of business data, when the mobile terminal M sends a resource allocation request for the batch for the first time, the resource The urgency information with time information included in the allocation request is the above-mentioned average generation time. If the same batch of business data cannot be sent to base station B after mobile terminal M sends the resource allocation request for the first time, then mobile terminal M is the remaining part of the batch of business data (it may also be the batch of All of the service data) resend resource allocation requests, and the resent resource allocation requests include information indicating resend until the batch of service data is sent completely. Then do the same for the next batch of business data. Among them, the information indicating retransmission can b...

Abstract

The present invention proposes a technical solution for requesting and allocating resources. The base station allocates resources for each mobile terminal in a certain order based on certain criteria and according to the urgency information with time information of the data to be transmitted in multiple mobile terminals. , so as to provide more average service delay and better system fairness. The waiting time information of the service data to be transmitted of the mobile terminal is added to the resource allocation request of the mobile terminal to express a certain degree of urgency of the service data to be transmitted, which overcomes the problem that the existing base station assigns multiple mobile terminals according to the resource allocation request. When using resources, it is impossible to understand the time urgency of mobile terminal business data, and it is possible to distinguish resource allocation requests with different time urgency and determine the order in which resources are allocated to multiple mobile terminals according to predetermined rules. The average service delay of the system improves the performance of the wireless communication network.

Description

technical field [0001] The present invention relates to a method and a device for requesting and allocating communication resources in the field of wireless communication, in particular to a method and a device for requesting resource allocation in a mobile terminal, a method and a device for controlling resource allocation in a base station, and a method and a device for controlling resource allocation in a relay station. A method and device for assisting in controlling resource allocation. Background technique [0002] In the field of wireless communication, the request and allocation of wireless communication resources is an important issue. In various communication modes, their respective methods for requesting and allocating wireless communication resources have been developed. For example, in a WiMAX system, requesting and allocating wireless communication resources are performed in a Demand Assigned Multiple Access (DAMA, Demand Assigned Multiple Access) manner. In t...
