Abstract

Aspects of the present disclosure provide techniques for wireless communications by a user equipment (UE). An exemplary method, performed by a UE, generally includes receiving a physical broadcast channel (PBCH), and determining, based on a first one or more bits in the PBCH, whether a second one or more bits in the PBCH are used to indicate control information for communications related to a first type of applications or a second type of applications.

Claims (86)

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

receiving a physical broadcast channel (PBCH); and

determining, based on a first one or more bits in the PBCH, whether a second one or more bits in the PBCH are used to indicate control information for communications related to a first type of applications or a second type of applications.

2. The method of claim 1 , wherein:

the first type of applications comprises machine type communications (MTC) applications; and

the second type of applications comprises non-MTC applications.

3. The method of claim 2 , wherein:

the first one or more bits comprise one bit, with different combinations of bit values indicating MTC or non-MTC.

4. The method of claim 2 , wherein:

the first one or more bits comprise at least two bits, with different combinations of bit values indicating MTC without coverage enhancement, MTC with coverage enhancement, non-MTC without coverage enhancement, or non-MTC with coverage enhancement.

5. The method of claim 1 , wherein:

one or more bits of the first one or more bits comprises a service indicator indicating a purpose of one or more of the second one or more bits.

6. The method of claim 1 , wherein:

a first bit of the first one or more bits comprises an machine type communications (MTC) indicator; and

a second bit of the first one or more bits comprises a coverage enhancement (CE) indicator.

7. The method of claim 6 , wherein:

a first combination of values of the MTC and CE indicators indicates the second one or more bits are reserved; and

a second combination of values of the MTC and CE indicators indicates the second one or more bits are used to indicate at least one of a time frequency position of a system information block (SIB), a transport block size of the SIB, or a control format indicator (CFI).

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

transmitting a physical broadcast channel (PBCH); and

indicating, via a first one or more bits in the PBCH, whether a second one or more bits in the PBCH are used to indicate control information for communications related to a first type of applications or a second type of applications.

9. The method of claim 8 , wherein:

the first type of applications comprises machine type communications (MTC) applications; and

the second type of applications comprises non-MTC applications.

10. The method of claim 9 , wherein:

the first one or more bits comprise one bit, with different combinations of bit values indicating MTC or non-MTC.

11. The method of claim 9 , wherein:

12. The method of claim 8 , wherein:

one or more bits of the first one or more bits comprises a service indicator indicating a purpose of one or more of the second one or more bits.

13. The method of claim 8 , wherein:

a first bit of the first one or more bits comprises an machine type communications (MTC) indicator; and

a second bit of the first one or more bits comprises a coverage enhancement (CE) indicator.

14. The method of claim 13 , wherein:

a first combination of values of the MTC and CE indicators indicates the second one or more bits are reserved; and

15. An apparatus for wireless communications, comprising:

means for receiving a physical broadcast channel (PBCH); and

means for determining, based on a first one or more bits in the PBCH, whether a second one or more bits in the PBCH are used to indicate control information for communications related to a first type of applications or a second type of applications.

16. The apparatus of claim 15 , wherein:

the first type of applications comprises machine type communications (MTC) applications; and

the second type of applications comprises non-MTC applications.

17. The apparatus of claim 16 , wherein:

the first one or more bits comprise one bit, with different combinations of bit values indicating MTC or non-MTC.

18. The apparatus of claim 16 , wherein:

19. The apparatus of claim 15 , wherein:

one or more bits of the first one or more bits comprises a service indicator indicating a purpose of one or more of the second one or more bits.

20. The apparatus of claim 15 , wherein:

a first bit of the first one or more bits comprises an machine type communications (MTC) indicator; and

a second bit of the first one or more bits comprises a coverage enhancement (CE) indicator.

21. The apparatus of claim 20 , wherein:

a first combination of values of the MTC and CE indicators indicates the second one or more bits are reserved; and

22. An apparatus for wireless communications, comprising:

means for transmitting a physical broadcast channel (PBCH); and

means for indicating, via a first one or more bits in the PBCH, whether a second one or more bits in the PBCH are used to indicate control information for communications related to a first type of applications or a second type of applications.

23. The apparatus of claim 22 , wherein:

the first type of applications comprises machine type communications (MTC) applications; and

the second type of applications comprises non-MTC applications.

24. The apparatus of claim 23 , wherein:

the first one or more bits comprise one bit, with different combinations of bit values indicating MTC or non-MTC.

25. The apparatus of claim 23 , wherein:

26. The apparatus of claim 22 , wherein:

one or more bits of the first one or more bits comprises a service indicator indicating a purpose of one or more of the second one or more bits.

27. The apparatus of claim 22 , wherein:

a first bit of the first one or more bits comprises an machine type communications (MTC) indicator; and

a second bit of the first one or more bits comprises a coverage enhancement (CE) indicator.

28. The apparatus of claim 27 , wherein:

a first combination of values of the MTC and CE indicators indicates the second one or more bits are reserved; and

29. An apparatus for wireless communications, comprising:

a receiver configured receive a physical broadcast channel (PBCH);

at least one processor configured to determine, based on a first one or more bits in the PBCH, whether a second one or more bits in the PBCH are used to indicate control information for communications related to a first type of applications or a second type of applications; and

a memory coupled to the at least one processor.

30. An apparatus for wireless communications, comprising:

a transmitter configured to transmit a physical broadcast channel (PBCH);

at least one processor configured to indicate, via a first one or more bits in the PBCH, whether a second one or more bits in the PBCH are used to indicate control information for communications related to a first type of applications or a second type of applications; and

a memory coupled to the at least one processor.

31. A non-transitory computer-readable medium for wireless communications by a user equipment (UE), the non-transitory computer-readable medium having computer-executable code stored thereon, comprising:

code for receiving a physical broadcast channel (PBCH); and

code for determining, based on a first one or more bits in the PBCH, whether a second one or more bits in the PBCH are used to indicate control information for communications related to a first type of applications or a second type of applications.

32. A non-transitory computer-readable medium for wireless communications by a base station (BS), the non-transitory computer-readable medium having computer-executable code stored thereon, comprising:

code for transmitting a physical broadcast channel (PBCH); and
