摘要： Data is transmitted and received in a TDMA frequency hopping system by allocating two or more time slots for transmitting identical data packets, and transmitting the identical data packets in the allocated time slots at different frequencies. This requires the transmission of redundant information but reduces the likelihood of data loss. An adaptive scheme may be employed wherein more time slots are allocated for the repeated data transmissions in areas of poor reception while fewer time slots are allocated for the repeated data transmissions in areas of higher quality reception or when higher bandwidth is required.
摘要翻译：通过分配用于发送相同数据分组的两个或更多个时隙并在不同频率的分配的时隙中发送相同的数据分组，在TDMA跳频系统中发送和接收数据。这需要传输冗余信息，但是降低数据丢失的可能性。可以采用自适应方案，其中在接收不良的区域中为重复的数据传输分配更多的时隙，而在较高质量接收的区域中或当需要更高的带宽时，为更重要的数据传输分配较少的时隙。

摘要： A method for communication in a sequence of frames includes assigning a respective time slot to each of a plurality of mobile units, while reserving an unassigned time slot. During a first frame, one of the mobile units transmits an uplink signal in the respective time slot, carrying first uplink data over the air to a base station. The base station transmits a downlink signal to the mobile unit indicating that retransmission of the first uplink data is required. Responsively to the downlink signal, during a second frame subsequent to the first frame, the mobile unit transmits the uplink signal both in the respective time slot and in the reserved time slot so as to carry the first uplink data and second uplink data over the air to the base station. A similar method may be used for downlink retransmission.
