Abstract

Claims (40)

1. A method of transmitting uplink data by a communications device in a wireless communications network, the method comprising:

receiving an indication of first communications resources allocated for a transmission of data by the communications device and associated with encoding parameters,

determining that first uplink data is available for transmission,

selecting the first communications resources for the transmission of the first uplink data,

selecting encoding parameters different from the encoding parameters associated with the first communications resources,

forming a transport block comprising the first uplink data in accordance with the selected encoding parameters, and

transmitting, using the first communications resources, the transport block and an indication of the selected encoding parameters, the indication of the selected encoding parameters being transmitted as one bit in hybrid automatic repeat request (HARQ) feedback, the method further comprising:

receiving an indication of the encoding parameters associated with the first communications resources, the indication of the encoding parameters comprising a first index value associated with a first row of a first predetermined table of encoding parameters, wherein

the selected encoding parameters are selected from a second row of a second predetermined table of encoding parameters, the second row associated with a second index value, the second index value being determined from the first index value according to a predetermined rule.

2. The method according to claim 1 , the method comprising:

receiving an indication of second communications resources available for a transmission of data by the communications device,

wherein the first communications resources comprise a portion of the second communications resources.

3. The method according to claim 2 , wherein the second communications resources are periodic.

4. The method according to claim 1 , the method comprising:

determining that second uplink data is available for transmission, the second uplink data associated with a lower priority than the first uplink data,

transmitting to an infrastructure equipment of the wireless communications network a request for an allocation of communications resources for the transmission of the second uplink data, wherein

the indication of the first communications resources is transmitted by the infrastructure equipment in response to receiving the request for the allocation.

5. The method according to claim 4 , wherein the second uplink data is associated with a requirement for a maximum permitted latency that is longer than a maximum permitted latency associated with the first uplink data.

6. The method according to claim 4 , wherein the second uplink data is associated with an Enhanced Mobile Broadband service.

7. The method according to claim 1 , the method comprising:

receiving a permission indication, the permission indication indicating that the communications device may select encoding parameters different from those associated with the first communications resources.

8. The method according to claim 1 , wherein the selected encoding parameters are selected from a plurality of permitted encoding parameters.

9. The method according to claim 8 , the method comprising:

determining the plurality of permitted encoding parameters based on the encoding parameters associated with the first communications resources.

10. The method according to claim 1 , wherein the indication of the selected encoding parameters comprises an indication that the selected encoding parameters differ from the encoding parameters associated with the first communications resources.

11. The method according to claim 1 , the method comprising:

receiving downlink data,

determining whether the downlink data has been decoded correctly, and

determining whether acknowledgement information indicating whether the downlink data has been decoded correctly is to be transmitted using the first communications resources.

12. A method of receiving uplink data by an infrastructure equipment in a wireless communications network, the method comprising:

transmitting an indication of first communications resources allocated for a transmission of data by a communications device and associated with encoding parameters,

receiving, using the first communications resources, a transport block and an indication of selected encoding parameters,

decoding from the transport block the uplink data in accordance with the indication of the selected encoding parameters,

wherein the selecting encoding parameters are different from the encoding parameters associated with the first communications resources, and

the indication of the selected encoding parameters is transmitted as one bit in hybrid automatic repeat request (HARQ) feedback, and

the indication of the encoding parameters includes a first index value associated with a first row of a first predetermined table of encoding parameters, and

the encoding parameters are selected from a second row of a second predetermined table of encoding parameters, the second row associated with a second index value, the second index value being determined from the first index value according to a predetermined rule.

13. The method according to claim 12 , the method comprising:

transmitting an indication of second communications resources available for a transmission of data by a communications device, wherein

the first communications resources comprise a portion of the second communications resources.
