摘要:
A method of operating a time division multiple access (TDMA) radio system having multi-slot capabilities and utilizing half-duplex transmission/reception where uplink and downlink user data transmissions between a mobile station (MS) 2 and a base station (BS) 3 are made in separate TDMA frames. A greater number of time slots are allocated to the mobile station 2 in each downlink TDMA frame than in each uplink TDMA frame to improve the efficiency of radio resource allocation and of the radio module 4 of the mobile station 2.
摘要:
A mobile station comprises means (301, 302, 303, 304, 326) for receiving downlink data from test equipment and means (331, 310, 311, 312, 313) for sending uplink data to the test equipment. To test data channel operation a test loop (204, 332, 333) is established to loop downlink data received from the test equipment back to the uplink direction to the test equipment. During the test, the reception of downlink data and transmission of uplink data in the mobile station are controlled by a relatively low protocol level.
