System and method for delay scheduling
A method includes determining a first subframe on which to transmit a first downlink control information (DCI) message and determining a second subframe on which to transmit a first information, where the first information is scheduled to be transmitted on the second subframe in accordance with scheduling information indicated in the first DCI message. The method also includes determining a delay between the first subframe and the second subframe and transmitting, by a communications controller to a user equipment (UE), the second subframe in accordance with the delay.
1. A method comprising:
determining a first subframe on which to transmit a first downlink control information (DCI) message;
determining a second subframe on which to transmit a first information, wherein the first information is scheduled to be transmitted on the second subframe in accordance with scheduling information indicated in the first DCI message;
determining a delay between the first subframe and the second subframe; and
transmitting, by a communications controller to a user equipment (UE), the second subframe in accordance with the delay.
2. The method of claim 1 , wherein the delay is fixed.
3. The method of claim 1 , wherein the delay is zero.
4. The method of claim 1 , wherein the second subframe is a subframe of a physical downlink shared channel (PDSCH).
5. The method of claim 1 , wherein determining the delay between the first subframe and the second subframe comprises determining the delay between the first subframe and the second subframe in accordance with a capability of the UE.
6. The method of claim 1 , wherein determining the delay between the first subframe and the second subframe comprises determining the delay in accordance with the first information.
7. The method of claim 1 , wherein the first DCI message comprises a field indicating the delay.
8. The method of claim 1 , further comprising transmitting, by the communications controller to the UE, the delay on higher layer signaling.
9. The method of claim 1 , wherein the second subframe further comprises a second DCI message, wherein the second DCI message indicates scheduling of the first information.
10. The method of claim 9 , wherein the first DCI message corresponds to a first device category of the UE and the second DCI message corresponds to a second device category of the UE.
11. The method of claim 1 , wherein the first subframe comprises a second information, wherein the first DCI message indicates scheduling of the second information.
12. The method of claim 1 , further comprising determining whether the communications controller supports different device categories.
13. A method comprising:
receiving, by a user equipment (UE) from a communications controller, symbols of a first subframe comprising a downlink control information (DCI) message;
receiving, by the UE from the communications controller, symbols of a second subframe in accordance with a delay, wherein the symbols of the second subframe comprise information, and wherein the DCI message indicates scheduling of the information; and
obtaining the delay.
14. The method of claim 13 , wherein obtaining the delay comprises receiving, by the UE from the communications controller, the delay.
15. The method of claim 13 , wherein obtaining the delay comprises obtaining the delay by a higher layer signaling.
16. The method of claim 13 , further comprising transmitting, by the UE to the communications controller, an acknowledgment delay after receiving the symbols in accordance with the information and the delay.
17. The method of claim 16 , wherein the acknowledgment delay is at least four subframes.
18. The method of claim 13 , wherein receiving the symbols of the second subframes comprises receiving the symbols of the second subframe in accordance with a capability of the UE.
19. A communications controller comprising:
a processor; and
a non-transitory computer readable storage medium storing programming for execution by the processor, the programming including instructions to
determine a first subframe on which to transmit a first downlink control information (DCI) message,
determine a second subframe on which to transmit a first information, wherein the first information is scheduled to be transmitted on the second subframe in accordance with scheduling information indicated in the first DCI message,
determine a delay between the first subframe and the second subframe, and
transmit, to a user equipment (UE), the second subframe in accordance with the delay.
20. A user equipment (UE) comprising:
a processor; and
a non-transitory computer readable storage medium storing programming for execution by the processor, the programming including instructions to
receive, from a communications controller, symbols of a first subframe comprising a downlink control information (DCI) message,
receive, from the communications controller, symbols of a second subframe in accordance with a delay, wherein the symbols of the second subframe comprise information, and wherein the DCI message indicates scheduling of the information, and
obtain the delay.
