Prioritizing high speed train (hst) cells over non-hst cells

A method of wireless communication performed by a user equipment (UE), comprising:

• receiving, from a high speed train (HST) cell, a system information block (SIB) indicating an HST flag based at least in part on the UE camping on the HST cell;
• disconnecting from the HST cell and camping on a non-HST cell based at least in part on a UE mobility in an HST railway;
• and
• determining that disconnecting from the non-HST cell and camping on a new HST cell is to be prioritized over remaining on the non-HST cell, based at least in part on the UE being in the HST railway and based at least in part on a priority of HST cells being greater than a priority of non-HST cells.

A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to:
• receive, from a high speed train (HST) cell, a system information block (SIB) indicating an HST flag based at least in part on the UE camping on the HST cell;
• disconnect from the HST cell and camp on a non-HST cell based at least in part on a UE mobility in an HST railway;
• and
• determine that disconnecting from the non-HST cell and camping on a new HST cell is to be prioritized over remaining on the non-HST cell based at least in part on the UE being in the HST railway and based at least in part on a priority of HST cells being greater than a priority of non-HST cells.

An apparatus for wireless communication, comprising:

• means for receiving, from a high speed train (HST) cell, a system information block (SIB) indicating an HST flag based at least in part on the apparatus camping on the HST cell;
• means for disconnecting from the HST cell and camping on a non-HST cell based at least in part on an apparatus mobility in an HST railway;
• and
• means for determining that disconnecting from the non-HST cell and camping on a new HST cell is to be prioritized over remaining on the non-HST cell based at least in part on the apparatus being in the HST railway and based at least in part on a priority of HST cells being greater than a priority of non-HST cells.
