Abstract

Aspects of the present disclosure provided techniques that for wireless communications by a user equipment (UE). An exemplary method, performed by a UE, generally includes determining one or more locations for receiving system information for machine type communication (MTC) over a bundled transmission and decoding the system information received at the locations over the bundled transmission.

Claims

1. A method for wireless communications by a user equipment (UE), comprising:

determining one or more locations for receiving system information for machine type communication (MTC) over a bundled transmission; and

decoding the system information received at the locations over the bundled transmission.

2. The method of claim 1, wherein the determination of the locations is dependent, at least in part, on one or more services supported by the UE.

3. The method of claim 2, wherein the services supported by the UE is dependent, at least in part, on a service bandwidth.

4. The method of claim 2, wherein the determination of the locations is dependent, at least in part, on whether the UE supports multicast broadcast media service (MBMS).

5. The method of claim 4, wherein the determination is based on an MBMS configuration provided to the UE in a broadcast transmission.

6. The method of claim 4, wherein determining comprises:

decoding an MTC-specific control channel with scheduling information indicating the locations.

7. The method of claim 6, further comprising determining one or more subframes in which the MTC-specific control channel may be transmitted based on MBMS configuration information provided to the UE.

8. The method of claim 1, wherein determining the locations comprises determining one or more fixed locations for transmission of the system information.

9. The method of claim 1, wherein determining the locations comprises determining one or more fixed times for transmission of the system information.

10. The method of claim 1, wherein content of the system information is fixed over a period of the bundled transmission.

11. The method of claim 10, wherein at least one of a modulation and coding scheme (MCS) or redundancy version (RV) for the system information is fixed over the period of the bundled transmission.

12. The method of claim 11, further comprising receiving an indication of at least one of the locations, MCS, or RV for the system information for a subsequent bundled transmission via a broadcast channel.

13. The method of claim 1, wherein determining the locations comprises determining a pair of alternating frequency locations for transmission of the system information.

14. A method for wireless communications by a base station (BS), comprising:

determining one or more locations for transmitting system information for machine type communication (MTC) over a bundled transmission to a user equipment (UE); and

transmitting the system information at the locations over the bundled transmission.

15. The method of claim 14, wherein the determination of the locations is dependent, at least in part, on one or more services supported by the UE.

16. The method of claim 15, wherein the services supported by the UE is dependent, at least in part, on a service bandwidth.

17. The method of claim 15, wherein the determination of the locations is dependent, at least in part, on whether the UE supports multicast broadcast media service (MBMS).

18. The method of claim 17, wherein the determination is based on MBMS configuration provided to the UE in a broadcast transmission.

19. The method of claim 17, further comprising transmitting, to the UE, an MTC-specific control channel with scheduling information indicating the locations.

20. The method of claim 19, further comprising determining one or more subframes in which the MTC-specific control channel may be transmitted based on an MBMS configuration information provided to the UE.

21. The method of claim 14, wherein determining the locations comprises determining one or more fixed locations for transmission of the system information.

22. The method of claim 14, wherein determining the locations comprises determining one or more fixed times for transmission of the system information.

23. The method of claim 14, wherein content of the system information is fixed over a period of the bundled transmission.

24. The method of claim 23, wherein at least one of a modulation and coding scheme (MCS) or redundancy version (RV) for the system information is fixed over the period of the bundled transmission.

25. The method of claim 24, further comprising transmitting, to the UE, an indication of at least one of the locations, MCS, or RV for the system information for a subsequent bundled transmission via a broadcast channel.

26. The method of claim 14, wherein determining the locations comprises determining a pair of alternating frequency locations for transmission of the system information.

27. An apparatus comprising at least one processor and a memory coupled to the at least one processor with instructions stored thereon, wherein:

the at least one processor is configured to;

determine one or more locations for receiving system information for machine type communication (MTC) over a bundled transmission; and

decode the system information received at the locations over the bundled transmission.

28. The apparatus of claim 27, wherein the determination of the locations is dependent, at least in part, on one or more services supported by the UE.

29. An apparatus comprising at least one processor and a memory coupled to the at least one processor with instructions stored thereon, wherein:

the at least one processor is configured to;

determine one or more locations for transmitting system information for machine type communication (MTC) over a bundled transmission to a user equipment (UE); and

transmit the system information at the locations over the bundled transmission.

30. The apparatus of claim 29, wherein the determination of the locations is dependent, at least in part, on one or more services supported by the UE.
