The disclosure provides a method and system for feeding back channel measurement information. The method includes: a receiving station receives a control frame for a channel measurement from a sending station, and sends channel measurement information to the sending station; the sending station correctly receives the channel measurement information or a part of the channel measurement information to obtain a valid response frame responding to the control frame for the channel measurement. Through the above solutions, if the sending station only correctly receives a part of the channel measurement information, the sending station does not consider this transmission is failed but consider that the valid response frame responding to the control frame for the channel measurement is obtained, so as to avoid unnecessary withdraw and retransmission, thereby saving bandwidth resources.

The disclosure discloses an identifier assignment method in a Wireless Local Area Network (WLAN), which includes: a group identifier is set for a non-Access Point Station (STA). The method further includes: in a process during which the STA associates or reassociates to an Access Point (AP), a terminal identifier is assigned to the associated or reassociated STA or a terminal identifier and a group identifier are assigned to the associated or reassociated STA. The disclosure also discloses an identifier assignment device in a WLAN for implementing the terminal access method. The terminal identifier is significantly expanded through the setting of the group identifier, so that a unique identifier can be assigned to the STA accessing to the AP without identifier repetition of the STA. Meanwhile, the grouping of the STA also facilitates the scheduling and management of the STA in a group. The disclosure ensures that sufficient STAs can access to the AP and a different identifier can be assigned to each STA.

The disclosure discloses an Identifier (ID) allocation method, including that: a non-AP Station (STA) sends a first radio frame to an Access Point (AP); and the AP sends a second radio frame to the STA, wherein the second radio frame carries group ID information or group ID information and second station ID information allocated to the STA. In a case that the STA sends a Reassociation Request frame to the AP, the AP may also send the STA a Reassociation Response frame carrying group ID information and/or station ID information reallocated to the STA. Correspondingly, the disclosure further discloses an ID allocation system. With the disclosure, a terminal is distinguished by the group ID information and the station ID information, such that it is possible to avoid Association ID (AID) shortage and support group management of terminals.

The present disclosure discloses a method for achieving backward compatibility in a large bandwidth wireless network and an Access Point (AP) for solving the technical problem of compatibility between a more effective channelization solution and a plurality of existing channelization solutions. The technical solution of the disclosure is implemented on the basis of time division multiplexing and frequency division multiplexing, and under the time division multiplexing mode, the AP sends/receives wireless frames on channels belonging to a first and a second channelization set respectively and alternately in terms of time according to a communication protocol; and under the frequency division multiplexing mode, the AP independently configures time window parameters and the corresponding main and/or secondary channel parameters on the channels which belong to the first and second channelization sets and are non-overlapped in the frequency domain, and sends/receives the wireless frames. By way of the above solution of the disclosure, the wireless station can establish a large bandwidth wireless network supporting backward compatibility.

A data transmission method and system are disclosed. The method comprises: a sending station sends a radio frame and notifies group transmission time interval information; a group station receives the radio frame and acquires group transmission time interval information of a group to which the group station belongs; and the group station competes for a sending opportunity within the group transmission time interval of the group to which the group station belongs. In accordance with the scheme provided in embodiments of the disclosure, a sending station allocates specific group transmission time intervals (subsections) to stations of different groups, and in the case of a large number of users stations, user stations in different groups compete for channels within different time intervals, thereby avoiding the simultaneous or approximately simultaneous competition among a large number of users, reducing the probability of collisions and improving the utilization efficiency of wireless resources.

The present invention relates to a load balancing method for a wireless local area network, which includes the following steps: initializing the load balancing group, self-organizing to select an online access point from the load balancing group as a load balancing agent center, each access point of the said balancing group managing and processing the load balance in accordance with the load level and balance optimizing policy, therefore implements the network load balance. The method of the invention improves reliability of the network load information, presents the load information from invalidly broadcasting in the wireless local area network, therefore reduces the additional overhead for managing the load balance of the wireless network, particularly in the network that having three layers switching equipment, self-organizing to select the agent center can utilize the network resource in effect, therefore managing the dynamic load balance information much more effectively, reducing the dependence on the upper server, and managing the network much more flexibly.

The invention discloses a method for wireless terminal dynamically switching window in a wireless LAN environment. The wireless LAN comprises several access points and stations which establish wireless communication connections with the access points. The stations can switch the current access window by scanning. The method characterizes in that including following steps: giving the switching window an initial value through the stations; the stations judge if there is another access point of which the signal quality is greater than that of the current access window through scanning wireless channels; if so, further judge if the stations are in a frequently handoff status, if so, the handoff judging result is not allowed to switch window; if not, the handoff judging result is allowed to switch window. The present invention can adaptively adjust the stations' switch windows according to the stations' handoff status and frequently handoff status. On one hand, the invention avoids the occurring of frequently handoff by changing the handoff conditions of the stations, increasing the access efficiency of the stations which is in the handoff status and in a wireless LAN environment, while maintaining the sensitivity of the stations which is in the handoff status, ensuring the quality of the wireless links between the stations and the access points.
