Title: Mobile communication terminal and method of detecting received signal strength
IPC: H04W36/36
Filed: 2000-08-10
Abstract: A determining section 106 compares received signal strengths of the respective pilot signals stored in a strength table 105 with a predetermined threshold of received signal strength, and reports a pilot signal exceeding the predetermined threshold to a control section 107. The control section 107 instructs a strength extracting section 104 to increase the number of received signal strength extraction times of the pilot signal exceeding the predetermined threshold. The strength extracting section 104 extracts received signal strengths from the respective pilot signals based on the instructed number of times. The strength table 105 detects the received signal strengths of the respective pilot signals at timing when the number of received signal strength extraction times reaches the predetermined number of times. <IMAGE>

Abstract: PURPOSE: A wireless communication system using a multi-element antenna having a space-time system is provided to increase the capacity of a multiple-input and multiple-output system. CONSTITUTION: Each sub-stream(125-1¯125-4) of a primary data stream(115) is stratified to produce processed sub-streams(635-1,635-2,635-3,635-4) whose strata(632-11¯632-44) are separated out and decoded with an acceptable error rate. The sub-stream(125-1¯125-4) is stratified by dividing it into a plurality of sub-stream-components(625-11¯625-44) that are processed to obtain strata(632-11¯632-44), with each stratum(632-11¯632-44) representing one of the sub-stream-components(625-11¯625-44). The strata(632-11¯632-44) are then combined to obtain the processed sub-stream(635-1¯635-4). Stratifying allows a particular processed sub-stream's strata(632-11¯632-44) to have different transmit features from each other, such as different bit rates, or different power levels, or both. This reduces the interference for some of the strata(632-11¯632-44) of each processed sub-stream since they are no longer interference for the other strata according as stratum are separated out and decoded.
