Abstract
Certain aspects of the present disclosure relate to methods and apparatus for conveying timing information that changes across a transmission time interval (TTI) in which multiple redundancy versions of a physical broadcast channel (PBCH) are transmitted.
Claims32
A method for wireless communications by a base station, comprising:
- determining, based on a physical broadcast channel (PBCH) transmission periodicity and a duration of a PBCH transmission time interval (TTI), a first set of one or more bits of a timing reference number conveyed in the PBCH that change over a duration of the TTI;
- transmitting multiple versions of a physical broadcast channel (PBCH) within the TTI, including a second set of bits of the timing reference number that do not change over the duration of the TTI;
- and
- providing an indication, with each PBCH transmission, of the first set of bits of the timing reference number.

A method for wireless communications by a wireless device, comprising:
- determining, based on a physical broadcast channel (PBCH) transmission periodicity and a duration of a PBCH transmission time interval (TTI), a first set of one or more bits of a timing reference that change over a duration of the TTI;
- decoding at least one of multiple versions of a physical broadcast channel (PBCH) within the TTI, wherein including a second set of bits of the timing reference number that do not change over the duration of the TTI;
- and
- obtaining an indication, with each decoded PBCH transmission, of the first set of bits of the timing reference number.
