Abstract: The routing method for wireless transport service comprises a step of receiving a unicast frame from an associated client; determining whether a destination of the unicast frame is locally associated. A wireless node delivers the unicast frame to a final destination if positive, otherwise, determining whether an associated transport device of a destination can be determined.

Abstract: A method of channel allocation for respective radios is disclosed. The method begins by scanning within sectors of a phased array for retrieval of BSSIDs belonging to each beam of a particular channel in the sectors. Then, corresponding characterizing information is recorded for every BSSID located. Next, an initial channel allocation for the respective radios is formed. The initial channel allocation is compared with a plurality of predetermined channel allocation modes that include a first mode of Point-to-Point (PtP) linkage, a second mode of MultiPoint-to-Point (MPtP) linkage, a third mode of Point-to-MultiPoint (PtMP) linkage, and a fourth mode of MultiPoint-To-MultiPoint (MPtMP) linkage, and a mode out of the predetermined channel allocation modes is selected that best characterizes the initial channel allocation. The radios are configured based on the channel allocation and unbalanced loading is reduced by adding/subtracting a non-overlapped frequency channel of a radio to an unbalanced beam.

Abstract: In a multi-carrier and multi-rate CDMA system, a base station transmits an index tag to a number of mobile stations. The index tag has a length indicating a transmission rate and all index tags are nodes in a code tree. In the code tree, mother nodes and their child nodes block each other and are not assigned to the mobile stations at the same time. At the same time, index tags of nodes in the same level of the code tree map are orthogonal to each other. The mobile station constructs an index tag matrix according to the index tag. Then, the index tag matrix is multiplied with a generating matrix that is stored in every mobile station to generate a spreading factor matrix whose rows respectively correspond to different carriers.
