And aspect mesh network; Internodal binding can change; And therefore this backhaul data can transfer to different nodes with another route at different time; Particularly in mesh network, because linking, this backhaul can change in time, can adjust smart antenna and make and can be connected to different nodes and can not produce excessive interference to other nodes just very unimportant.
The node 102a-n of at least one part system provides at least one smart antenna (then will specify); And except general download transfers to WTRUs and is uploaded the reception by WTRUs; Still utilize this smart antenna transmission backhaul data to other node 102a-n; These nodes 102a-n has the ability to produce a plurality of sensing wave beams, and guides this wave beam to azimuth direction.
In one embodiment, node 102a-n has a plurality of as preset wave beam 109a-h shown in Figure 4, and between a plurality of wave beam 109a-h, selects one so that point to a transmission or reception.Eight sides shown in Figure 4 are wave beam, and it all can be produced by each node 102a-n, it should be noted that wave beam shown in Figure 4 is an example, and any amount of wave beam, beam modes or any type of pattern all can be carried out.
In another embodiment, each wave beam 109a-h can produce and point in real time, and need from preset location sets, not choose.
One execution mode of this System Operation is following: one first selects node; Node 102a for example; Produce a wave beam and guide it to select node towards other; 102b for example, this can reach through the compound weights that adjustment is used for this aerial array assembly, accomplishes general as typically forming aerial array by wave beam.At the same time, node 102a measures and links the quality of A to node 102b, and the quality of binding A can be indicated through signal noise ratio, position or frame error ratio or other measurement quality and measured.This transmission node 102a finds best antenna beam sensing, best weight value combination with this binding quality of maximization, and stores this binding mass measurement and corresponding beam position (weights).This transmission node 102a does these things and stores corresponding quality and wave beam information for all adjacent nodes.
Any node 102a-n can be flexibly and wirelessly is connected with other node 102a-n or breaks, and it is through selecting to point to one or more wave beams of other node 102a-n.In Fig. 1; This first node 102a uses and points to wave beam A message transfer to this Section Point 102b; And use and point to wave beam B message transfer to the four node 102d; Sensing wave beam A and sensing wave beam B are independent control and can transmit simultaneously, because each sensing wave beam A and sensing wave beam B only send towards a particular orientation, therefore can't cause excessive interference to other nodes 102a-n or WTRUs.
Shown in Figure 2 is according to node 202 calcspars of the present invention.This node 202 comprises a smart antenna 204, a controller 206, a memory 208 and a non-essential wired binding 210.This wired binding 210 can be linked to this core network 110 or other node.The multipath that this node 202 carries out that a signal processing algorithm moves to adapt to the user, the change of wireless frequency environment and common channel are disturbed.One RRM (RRM) function is carried out through this controller 206, and how this disposes in this node 202 with the decision Radio Resource.
Aspect mixed node 102n, this program be this smart antenna 204 help to set up down and the wireless link of other node after.When mixed node 102n sets up backhaul when being linked to this core network 110 or other node, do not need configuration info or beam selection, because fix on wired binding 210 entities, and always provide the binding between two nodes.
