Base station midamble selection

摘要

Midamble codes are selected in a wireless time division duplex communication system. At least one channelization code is assigned to a user equipment. A mapping is provided between midamble codes and channelization codes. At least one midamble code is mapped to a plurality of channelization codes having a same spreading factor. The midamble code mapped to the at least one channelization code to the user equipment is selected. A communication burst is formed with the assigned at least one channelization code and the selected midamble code.
