[0004] figure 1 The disadvantage of the contention-based bandwidth request process shown in is that: in a bandwidth allocation request, the base station and the mobile station interact too many times, if the mobile station does not receive the CDMA_Alloc_IE information sent by the base station in step S14, the mobile station After a period of time, a new CDMA codeword is selected to resend
For real-time interactive services, such delays may be unbearable, and it is necessary to improve this bandwidth request and allocation method

Embodiment Construction
[0025] figure 2 A schematic diagram of a partial network topology of a wireless communication system is shown, wherein a base station B manages a plurality of mobile stations M1, M2, M3, . . . , M10 and so on. image 3 It shows a system flowchart of fast bandwidth request and allocation between a mobile station and a base station according to a specific embodiment of the present invention. The following combination image 3 right figure 2 The process of fast bandwidth request and allocation between the base station B and the mobile station M1 will be described in detail.
[0026]First, in step S31, the base station B sends a first resource allocation notification message to the mobile station M1, the first resource allocation notification message includes the time-frequency resources of the time-frequency resource blocks used for each mobile station to randomly send the bandwidth allocation request message Information, the time-frequency resource block is shared by multip...

The present invention proposes a technical scheme for rapid bandwidth request and allocation for existing fault of bandwidth request and allocation in a wireless broadband access network, a mobile station transmits a bandwidth allocation request message for bandwidth allocation to a base station only once, which reduces interworking times between the base station and the mobile station, improves efficiency of bandwidth request and allocation, shortens effectively waiting time for sending service data, and especially improves support for data service sensitive to time delay. Since the present invention reduces interworking times between the base station and the mobile station, so that it saves kinds of process resources in the base station and mobile station. The base station can adjust the size of time frequency resource block for each mobile station transmitting bandwidth allocation request message according to the number of the mobile station domainated by the base station and / or service type in each mobile station, so that it can make the whole wireless communication system (including one base station and one or more mobile stations dominated by the base station) work more effectively.
Description
technical field [0001] The present invention relates to a base station and a mobile station in a wireless communication network, in particular to a method and device for requesting a base station to allocate resources for the mobile station and a method and device for allocating resources for the mobile station in the base station. Background technique [0002] In recent years, broadband wireless access technology has shown unprecedented prosperity in technology research and development and innovation. IEEE 802 series standards have developed rapidly, and technologies such as 802.11 and 802.16 have become the focus of attention in the wireless communication industry today. In the broadband wireless access network, in the downlink, the base station sends broadcast control data and service data to multiple mobile stations (or called user terminals) in a point-to-multipoint manner. In the uplink, multiple mobile stations send service data or control information, such as bandwid...
