Abstract

A method facilitating determination of transmission type via demodulation reference signal (DMRS) patterns is provided. In one example, the method can include generating information according to a protocol for receipt by a mobile device, wherein the information is indicative of a defined transmission type for the mobile device and wherein the protocol employs demodulation reference signal patterns; and transmitting the information to the mobile device. In some embodiments, the protocol comprises a first protocol in which the information comprises a first message transmitted in a first set of resources to communicate to the mobile device a first downlink control information (DCI) format associated with a first transmission type, and wherein the protocol further comprises a second protocol in which the information comprises a second message transmitted in a second set of resources to communicate to the mobile device a second DCI format associated with a second transmission type.

Claims (28)

1. An apparatus, comprising:

a processor; and

a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:

generating information according to a protocol for receipt by a mobile device, wherein the information is indicative of a defined transmission type for the mobile device and wherein the protocol employs demodulation reference signal patterns; and

transmitting the information to the mobile device, wherein the protocol comprises a first protocol in which the information comprises a first message transmitted with a first group of resources to the mobile device, the first message defining a first downlink control information format associated with a first transmission type, and wherein the protocol further comprises a second protocol in which the information comprises a second message transmitted with a second group of resources to the mobile device, the second message defining a second downlink control information format associated with a second transmission type.

2. The apparatus of claim 1 , wherein the first transmission type is indicative of a first demodulation reference signal pattern of the demodulation reference signal patterns.

3. The apparatus of claim 2 , wherein the first transmission type is a slot transmission type and wherein the second transmission type is a mini-slot transmission type.

4. The apparatus of claim 2 , wherein the second transmission type is indicative of a second demodulation reference signal pattern of the demodulation reference signal patterns.

5. The apparatus of claim 1 , wherein the information indicative of the defined transmission type is transmitted via a physical downlink control channel.

6. The apparatus of claim 1 , wherein the protocol comprises a first protocol in which the information comprises a first message transmitted in a first set of resources to the mobile device, wherein the first message comprises a first transmission type.

7. The apparatus of claim 6 , wherein the protocol further comprises a second protocol in which the information comprises a second message transmitted in a second set of resources to the mobile device, and wherein the second message comprises a second transmission type.

8. The apparatus of claim 7 , wherein the first transmission type is indicative of a first demodulation reference signal pattern, wherein the second transmission type is indicative of a second demodulation reference signal pattern, and wherein the second transmission type is different from the first transmission type.

9. The apparatus of claim 1 , wherein the protocol comprises a first protocol in which the information comprises a first message comprising a bitmap representative of defined information, wherein first information of the defined information is indicative of a first transmission type and wherein second information of the defined information is indicative of a second transmission type.

10. The apparatus of claim 9 , wherein the first transmission type comprises a slot transmission type and wherein the second transmission type comprises a mini-slot transmission type different from the first transmission type.

11. A method, comprising:

generating, by a device comprising a processor, information according to a protocol for receipt by a mobile device, wherein the information is indicative of a defined transmission type for the mobile device, and wherein the protocol employs demodulation reference signal patterns; and

transmitting, by the device, the information to the mobile device, wherein the protocol comprises a first protocol in which the information comprises a first message transmitted in first resources in order to communicate, to the mobile device, a first downlink control information format associated with a first transmission type, and wherein the protocol further comprises a second protocol in which the information comprises a second message transmitted in second resources to communicate, to the mobile device, a second downlink control information format associated with a second transmission type.

12. The method of claim 11 , wherein the first transmission type is indicative of a first demodulation reference signal pattern of the demodulation reference signal patterns, and wherein the second transmission type is indicative of a second demodulation reference signal pattern of the demodulation reference signal patterns, wherein the second transmission type is different from the first transmission type.

13. The method of claim 12 , wherein the first transmission type is a slot transmission type, and wherein the second transmission type is a mini-slot transmission type.

14. The method of claim 11 , wherein the protocol comprises a first protocol in which the information comprises a first message transmitted in first resources to communicate, to the mobile device, a first transmission type.

15. The method of claim 14 , wherein the protocol further comprises a second protocol in which the information comprises a second message transmitted in second resources to communicate, to the mobile device, a second transmission type.

16. The method of claim 15 , wherein the first transmission type is indicative of a first demodulation reference signal pattern, wherein the second transmission type is indicative of a second demodulation reference signal pattern, and wherein the second transmission type is different from the first transmission type.

17. A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:

receiving information according to a protocol from a base station device, wherein the information is indicative of a defined transmission type for the mobile device and wherein the protocol employs demodulation reference signal patterns; and

communicating information content based on the protocol, wherein the protocol comprises a first protocol in which the information comprises a first message transmitted in a first group of resources, wherein the first message communicates, to the mobile device, a first downlink control information format associated with a first transmission type, wherein the protocol further comprises a second protocol in which the information comprises a second message transmitted in a second group of resources, and wherein the second message communicates, to the mobile device, a second downlink control information format associated with a second transmission type.

18. The non-transitory machine-readable medium of claim 17 , wherein the first transmission type is indicative of a first demodulation reference signal pattern of the demodulation reference signal patterns, and wherein the second transmission type is indicative of a second demodulation reference signal pattern of the demodulation reference signal patterns.

19. The non-transitory machine-readable medium of claim 18 , wherein the first transmission type is a slot transmission type.

20. The non-transitory machine-readable medium of claim 19 , wherein the second transmission type is a mini-slot transmission type.
