| 1. A radio of a time division radio communications system comprising a transceiver for communicating with other radios of
the time division radio communication system over radio channels using a preestablished time division frame structure, the
preestablished frame structure comprising:
a sequence of uplink slots each having a predetermined duration, the uplink slots being for use at least in part in determining
spatial parameters for use in receiving subsequent uplink slots from the corresponding uplink transceiver;
a sequence of downlink slots following the sequence of uplink slots, each downlink slot being associated with an uplink slot,
each downlink slot having a predetermined duration that is greater than the duration of each of the uplink slots of the sequence,
the downlink slots being for use in sending data to the corresponding uplink transceiver using the determined spatial parameters
from the preceding uplink slots of the same frame;
an interburst guard time between each uplink slot;
an interburst guard time between each downlink slot; and
an interframe guard time after the sequence of downlink slots.
