Systems and methods for assignment and allocation of mixed-type combinations of slots
Methods and systems for performing allocation of mixed-type combinations of slots are provided. Specifically, in a single assignment message, an allocation of slots over two frames and slots over four frames is performed. These can be RTTI and BTTI blocks for example.
1. A method in network access equipment comprising:
transmitting a single assignment message that assigns a single temporary block flow, TBF, comprising a first mixed transmit time interval, TTI, combination of slots for time division multiple access, TDMA, communication unidirectionally in one of an uplink and a downlink;
wherein the first mixed TTI combination of slots in the single TBF is equal to an odd number of slots greater than or equal to three and comprises at least one pair of slots for reduced transmit time interval, RTTI, blocks and no more than one slot for basic transmit time interval, BTTI, blocks.
2. The method of claim 1 further comprising communicating based on the single assignment message.
3. The method of claim 2 , wherein communicating based on the assignment message comprises transmitting data blocks on the at least one pair of slots for RTTI blocks and the slot for BTTI blocks.
4. The method of claim 2 , wherein communicating based on the assignment message comprises receiving data blocks on the at least one pair of slots for RTTI blocks and the slot for BTTI blocks.
5. The method of claim 2 , wherein an RTTI block consists of a first pair of slots in a first TDMA frame and a second pair of slots in a second TDMA frame; and wherein a BTTI block consists of a slot in the first TDMA frame, a slot in the second TDMA frame, a slot in a third TDMA frame, and a slot in a fourth TDMA frame.
6. The method of claim 5 , wherein the single assignment message contains at least:
an indication that the assignment is a mixed TTI TBF assignment;
indication of slot(s) carrying BTTI block(s); and
indication of slot(s) carrying RTTI block(s).
7. The method of claim 5 , wherein the single assignment message comprises a packet uplink assignment message, a packet downlink assignment message, or a packet timeslot reconfigure message.
8. A method in user equipment, UE, comprising:
receiving a single assignment message that assigns a single temporary block flow, TBF, comprising a first mixed transmit time interval, TTI, combination of slots for time division multiple access, TDMA, communication unidirectionally in one of an uplink and a downlink;
wherein the first mixed TTI combination of slots in the single TBF is equal to an odd number of slots greater than or equal to three and comprises at least one pair of slots for reduced transmit time interval, RTTI, blocks and no more than one slot for basic transmit time interval, BTTI, blocks.
9. The method of claim 8 further comprising communicating based on the single assignment message.
10. The method of claim 9 , wherein communicating based on the assignment message comprises receiving data blocks on the at least one pair of slots for RTTI blocks and the slot for BTTI blocks.
11. The method of claim 9 , wherein communicating based on the assignment message comprises transmitting data blocks on the at least one pair of slots for RTTI blocks and the slot for BTTI blocks.
12. The method of claim 9 , wherein an RTTI block consists of a first pair of slots in a first TDMA frame and a second pair of slots in a second TDMA frame; and wherein a BTTI block consists of a slot in the first TDMA frame, a slot in the second TDMA frame, a slot in a third TDMA frame, and a slot in a fourth TDMA frame.
13. The method of claim 12 , wherein the single message contains at least:
an indication that the assignment is a mixed TTI TBF assignment;
indication of slot(s) carrying BTTI block(s); and
indication of slot(s) carrying RTTI block(s).
14. The method of claim 12 , wherein the single assignment message comprises a packet uplink assignment message, a packet downlink assignment message, or a packet timeslot reconfigure message.
15. A user equipment comprising:
a receive module configured to receive a single assignment message that assigns a single temporary block flow, TBF, comprising a first mixed transmit time interval, TTI, combination of slots for time division multiple access, TDMA, communication unidirectionally in one of an uplink and a downlink, the first mixed TTI combination of slots in the single TBF being equal to an odd number of slots greater than or equal to three and comprising at least one pair of slots for reduced transmit time interval, RTTI, blocks and no more than one slot for basic transmit time interval, BTTI, blocks.
16. The user equipment of claim 15 , wherein the receive module is configured to receive data blocks on the at least one pair of slots for RTTI blocks and the slot for BTTI blocks.
17. The user equipment of claim 16 , further comprising a transmit module configured to transmit data blocks on the at least one pair of slots for RTTI blocks and the slot for BTTI blocks.
18. The user equipment of claim 17 , wherein an RTTI block consists of a first pair of slots in a first TDMA frame and a second pair of slots in a second TDMA frame; and wherein a BTTI block consists of a slot in the first TDMA frame, a slot in the second TDMA frame, a slot in a third TDMA frame, and a slot in a fourth TDMA frame.
19. The user equipment of claim 18 , wherein the single message contains at least:
an indication that the assignment is a mixed TTI TBF assignment;
indication of slot(s) carrying BTTI block(s); and
indication of slot(s) carrying RTTI block(s).
20. The user equipment of claim 18 , wherein the single assignment message comprises a packet uplink assignment message, a packet downlink assignment message, or a packet timeslot reconfigure message.
21. A network access equipment comprising:
a transmit module configured to transmit a single assignment message that assigns a single temporary block flow, TBF, comprising a first mixed transmit time interval, TTI, combination of slots for time division multiple access, TDMA, communication unidirectionally in one of an uplink and a downlink, the first mixed TTI combination of slots in the single TBF being equal to an odd number of slots greater than or equal to three and comprising at least one pair of slots for reduced transmit time interval, RTTI, blocks and no more than one slot for basic transmit time interval, BTTI, blocks.
22. The network access equipment of claim 21 , wherein the transmit module is configured to transmit data blocks on the at least one pair of slots for RTTI blocks and the slot for BTTI blocks.
23. The network access equipment of claim 22 , further comprising a receive module configured to receive data blocks on the at least one pair of slots for RTTI blocks and the slot for BTTI blocks.
