Embodiment 1

[0036] Embodiment 1: RRA reports idle resources of BS to RRC

[0037] Such as image 3 shown, including the following steps:

[0038] S101. The RRC sends the RRM-Spare-capacity-request primitive to the RRA, requesting to report the idle wireless resources of the BS, including the information specifying the idle resources to be reported and the reporting conditions or reporting period. The idle resource information includes one of the following or random combination:

[0039] 1. The average value, maximum value and minimum value of the number of uplink idle OFDM symbols and the number of sub-channels within a statistical period T;

[0040] 2. The average value, maximum value and minimum value of the number of downlink idle OFDM symbols and the number of sub-channels within a statistical period T;

[0041] 3. The average value, maximum value and minimum value of the number of idle OFDM symbols and the number of subchannels of each service currently provided;

[0042] General...

Embodiment 2

[0049] Embodiment 2: Exchange BS idle resource information between RRCs

[0050] As shown in Figure 5, RRC1 requests RRC2 to report the idle resource information of one or some BSs specified in its category. This situation is mainly used when the terminal needs to know the idle resources of these BSs when switching between BSs under different RRCs. Whether the information is running or not is switched, and the specific process includes the following steps:

[0051] S201. RRC1 sends an RRM-Spare-capacity-request primitive to RRC2, requesting to report idle wireless resources of a designated BS, including resource information designated to be reported and identification information of the BS;

[0052] Still taking the OFDMA system as an example, the BS idle resource information that needs to be reported also includes one or any combination of the following:

[0053] 1. The average value, maximum value and minimum value of the number of uplink idle OFDM symbols and the number of...

Abstract

The invention relates to WiMAX communication technology, and discloses a method for acquiring idle resources of a base station in a WiMAX system, so as to solve the problem that accurate idle wireless resources of a BS cannot be acquired in the prior art. The method includes: the radio resource controller instructs the radio resource agent to report base station idle resource information and reporting conditions or reporting periods, and the idle resource information includes one or any combination of the following: uplink / downlink average idle resources, maximum idle resources , the minimum idle resource, and the currently available resources of each uplink / downlink service; the wireless resource agent periodically counts the idle resource information according to the set statistics period, and when the reporting condition is met or when the reporting period is reached, the latest The corresponding data counted in a counting period are reported to the radio resource controller. The above idle resource information may also be exchanged between radio resource controllers.

Description

technical field [0001] The present invention relates to WiMAX communication technology, in particular to a method and device for acquiring idle resources of a base station in a WiMAX system. Background technique [0002] The IEEE 802.16 standard defines the wireless metropolitan area network standard of BWA (Broadband Wireless Access). This standard defines different physical layer technologies for different frequency bands. and SME (Smail Enterprise, small business users) market. [0003] MAC (Media Access Control, media access control layer) defined in IEEE 802.16 supports very unfavorable user environments, can cope with the application environment that may have hundreds or thousands of users on each channel, and supports continuous and burst and other business volumes. It has an ATM (Asynchronous Transfer Mode, asynchronous transfer mode) convergence sublayer and a packet convergence sublayer, and encapsulates multiple high-level data units into a MAC PDU (Media Access...
