IPC: H04H20/67
Filed: 2009-04-07
Abstract: Techniques for sending information in a wireless network are described. The network may support (i) regular subframes used to send unicast information and (ii) multicast/broadcast single frequency network (MBSFN) subframes used to send broadcast information and having lower overhead than the regular subframes. In an aspect, MBSFN subframes may be used to mitigate interference. A first base station may cause high interference to stations (e.g., UEs) served by a second base station. The first base station may reserve a subframe for the second base station, send system information conveying the reserved subframe as an MBSFN subframe to its stations, and transmit in a first part of the reserved subframe in accordance with an MBSFN subframe format. The second base station may skip the first part and may send unicast information to its stations in the remaining part of the reserved subframe.

Title: Structure of shock absorbing rim
Inventor: Li zai-cheng
IPC: B60B9/02
Filed: 2009-04-24
Abstract: This invention is a structure of a shock absorbing rim. The shock absorbing wheel mainly comprises a rim. The inside of the rim defines a first capacity space which houses a suspension assembly. The suspension assembly has a connecting piece at which the lateral sides each have a fixed disc. The fixed disc defines multiple second fixed parts which connect to a center base. There is a second cavity space inside the center base that the lateral sides have corresponding lock-down parts. A fixture piece passes through the lock-down part and the second fixed part. A support piece passes through the second cavity space at the fixture piece. The far-end of the support piece is mounted together with the rim at the fixture piece. Furthermore, an elastic piece surrounds the outside of the support piece. As a result, a rotating rim obtains elasticity through the support piece of the elastic piece. Therefore, the rim achieves maximum shock absorbing effect on uneven surface.
