Abstract
In one embodiment, the present invention includes a repeating frame for a time division radio communications system with a sequence of uplink slots each having a predetermined duration, a sequence of downlink slots, each having a predetermined duration that is greater than the duration of the uplink slots, 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.
Claims72
A repeating frame for a time division radio communications system comprising:
- a sequence of uplink slots each having a predetermined duration;
- a sequence of downlink slots, each having a predetermined duration that is greater than the duration of the uplink slots;
- 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.
3 more elements
A method comprising:
- receiving bursts in a sequence of uplink slots of a repeating frame, each uplink slot having a predetermined duration, the uplink bursts each being separated by an uplink interburst guard time;
- transmitting bursts in a sequence of downlink slots of a repeating frame, each downlink slot having a predetermined duration that is greater than the duration of the uplink slots, the downlink bursts each being separated by a downlink interburst guard time;
- waiting for an interframe guard time after the sequence of downlink bursts;
- and repeating the frame.
1 more element
A machine-readable medium having stored thereon data representing instructions which, when executed by a machine, cause the machine to perform operations comprising:
- receiving bursts in a sequence of uplink slots of a repeating frame, each uplink slot having a predetermined duration, the uplink bursts each being separated by an uplink interburst guard time;
- transmitting a sequence of downlink slots of a repeating frame, each downlink burst having a predetermined duration that is greater than the duration of the uplink slots,
- the downlink bursts each being separated by a downlink interburst guard time;
- waiting for an interframe guard time after the sequence of downlink bursts;
- and repeating the frame.
2 more elements
A method comprising:
- transmitting a burst in a predetermined one of a sequence of uplink slots of a repeating frame, each uplink slot having a predetermined duration, the uplink burst being separated from other uplink bursts by an uplink interburst guard time;
- receiving a burst in a predetermined one of a sequence of downlink slots of a repeating frame, each downlink slot having a predetermined duration that is greater than the duration of the uplink slots, the downlink burst being separated from other downlink bursts by a downlink interburst guard time;
- waiting for an interframe guard time after the sequence of downlink bursts;
- and repeating the transmitting and receiving.
1 more element
An apparatus comprising:
- a receiver to receive bursts in a sequence of uplink slots of a repeating frame, each uplink slot having a predetermined duration, the uplink bursts each being separated by an uplink interburst guard time;
- a transmitter to transmit bursts in a sequence of downlink slots of a repeating frame, each downlink slot having a predetermined duration that is greater than the duration of the uplink slots, the downlink bursts each being separated by a downlink interburst guard time;
- and
- a processor to determine the duration of the interburst guard times and to suspend operation of the receiver and transmitter for an interframe guard time after the sequence of downlink bursts.
1 more element
An apparatus comprising:
- a transmitter to transmit a burst in a predetermined one of a sequence of uplink slots of a repeating frame, each uplink slot having a predetermined duration, the uplink bursts each being separated by an uplink interburst guard time;
- a receiver to receive a burst in a predetermined one of a sequence of downlink slots of a repeating frame, each downlink slot having a predetermined duration that is greater than the duration of the uplink slots, the downlink bursts each being separated by a downlink interburst guard time;
- and
- a processor to determine the duration of the interburst guard times and to suspend operation of the receiver and transmitter for an interframe guard time after the sequence of downlink bursts.
1 more element
A repeating frame for a time division radio communications system comprising:
- a sequence of uplink slots each having a predetermined duration, the uplink slots supporting a plurality of transmission modes;
- a sequence of downlink slots, each having a predetermined duration that is greater than twice the duration of the uplink slots, the downlink slots supporting a plurality of transmission modes, so that the ratio of the downlink data rate to the uplink data rate can be set at a variety of different values including values that are greater than two to one.
An apparatus comprising:
- means for receiving data in a sequence of uplink slots each slot having a predetermined duration, and the data in each slot being received in any one of a plurality of different predetermined transmission modes;
- means for transmitting data in a sequence of downlink slots, each slot having a predetermined duration that is greater than twice the duration of the uplink slots, the data in each downlink slots being transmitted in any one of a plurality of transmission modes;
- and
- means for selecting the transmission modes so that the ratio of the downlink data rate to the uplink data rate can be set at a variety of different values including values that are greater than two to one.
