Information exchanged method and device
First Claim
1. A method for exchanging information, the method comprising:
- determining, by a transmitting Access Point (AP), an air interface broadcast resource for transmitting information to a receiving AP; and
transmitting, by the transmitting AP, information to the receiving AP by broadcasting the information over the determined air interface broadcast resource;
wherein the determining, by the transmitting AP, the air interface broadcast resource for transmitting information to the receiving AP comprises;
determining, by the transmitting AP, the air interface broadcast resource as configured by a first network-side device, wherein the first network-side device is a cluster head AP;
ordetermining, by the transmitting AP, the air interface broadcast resource for transmitting information to the receiving AP from a pool of air interface broadcast resources configured by a second network-side device, wherein, the second network-side device transmits the configuration information of the pool of air interface broadcast resources to a cluster head AP in each set of the transmitting APs in a preset area range, so that the transmitting AP determines the air interface broadcast resources as configured by the cluster head AP;
wherein the cluster head AP is an AP selected from a set of APs comprising the transmitting AP, wherein any one AP in the set and the cluster head AP can receive air interface information transmitted from each other by broadcasting the information;
wherein after the transmitting AP selects the air interface broadcast resource for transmitting information to the receiving AP, the method further comprises;
transmitting, by the transmitting AP, resource preemption signaling to the receiving AP to indicate the air interface broadcast resource selected by the transmitting AP;
wherein the determining, by the transmitting AP, the air interface broadcast resource for transmitting information to the receiving AP comprises;
determining, by the transmitting AP, whether the selected air interface broadcast resource is preempted successfully, according to a feedback message of the receiving AP for the resource preemption signaling; and
determining, by the transmitting AP, the selected air interface broadcast resource as the air interface broadcast resource for transmitting information to the receiving AP, upon determining that the selected air interface broadcast resource is preempted successfully.

Abstract
An information exchange method and device for addressing a coordination problem between different access points (APs) caused by low exchange efficiency between the APs. The information exchange method provided in an embodiment of the present invention comprises: determining, by a transmitting AP, an air interface broadcast resource for transmitting information to a receiving AP; and transmitting, by the transmitting AP and based on the determined air interface broadcast resource, the information to the receiving AP in a broadcast form. Adopting the embodiment of the present invention not only allows an air interface transmission to be performed between the APs, but also allows communication between more than two APs. One AP can transmit information thereof, in the broadcast form, to all neighboring APs having a needing to exchange information therewith, thereby improving coordination efficiency between the APs.

7. A method for exchanging information, the method comprising:
-
determining, by a receiving Access Point (AP), an air interface broadcast resource occupied by a transmitting AP; and receiving, by the receiving AP, information transmitted from the transmitting AP by broadcasting the information, over the determined air interface broadcast resource; wherein the determining, by the receiving AP, the air interface broadcast resource occupied by the transmitting AP comprises; receiving, by the receiving AP, resource preemption signaling transmitted by any one transmitting AP, and determining an air interface broadcast resource indicated in the resource preemption signaling as the air interface broadcast resource occupied by the any one transmitting AP, wherein after the receiving AP receives the resource preemption signaling transmitted by the any one transmitting AP, the method further comprises; transmitting, by the receiving AP, a feedback message for the resource preemption signaling to the any one transmitting AP. - View Dependent Claims (8, 9)
