    Abstract: A base station (BS) may transmit, and a user equipment (UE) may receive, a physical broadcast channel, such as a narrowband physical broadcast channel (NB-PBCH). In an interference-limited scenario with synchronous cells in a network, repetitions of a symbol being transmitted for a first physical broadcast channel of a first cell may collide with repetitions of a symbol being transmitted for a second physical broadcast channel of a second cell. This may result in the UE being unable to recover symbols of a physical broadcast channel. In some aspects, the BS may transmit, and the UE may receive, a physical broadcast channel including bits processed using a first processing stage, such as using first scrambling sequences, and a second processing stage, such as using second scrambling sequences, to compensate for the interference, thereby ensuring that the UE can recover the symbols of the physical broadcast channel.

    Abstract: Various aspects of the disclosure relate to beam information for independent links. For example, beam information for one link may be sent on at least one other link. In some aspects, the independent links may involve a first device (e.g., a user equipment) communicating via different independent links with different devices (e.g., transmit receive points (TRPs) or sets of TRPs). For example, the first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., a TRP) via a second link. In some scenarios, one link can indicate beam switching for at least one other link. In some scenarios, one link can indicate link recovery for at least one other link. In some scenarios, one link can indicate link failure for at least one other link.

    Abstract: Due to the limited dimension of a NB that may be used by multiple users, as well as possible large coverage areas, timing offset estimation may be outside of NCP. The inaccuracy in the timing estimate can be improved by using more than one tone hopping distance for PRACH. An apparatus may then transmit a first and second tone of the PRACH at a first hopping distance from the first tone. The apparatus may then transmit a third tone of the PRACH and a fourth tone of the PRACH at a second hopping distance from the third tone. The second hopping distance may be greater than first hopping distance. The apparatus may also transmit an additional tone of the PRACH using a random hopping distance. A receiving apparatus may receive the transmitted PRACH and determine a phase estimation based on the sets of tones having different hopping distances.
