Method and apparatus for mitigating data loss during autonomous system information reading

An apparatus for wireless communication, comprising:

• means for suspending reception of downlink transmission from a serving cell by a user equipment (UE) during a system information (SI) reading gap;
• means for receiving system information from a neighbor cell by the UE during the SI reading gap;
• means for skipping updating at least one tracking loop for an uplink based on the serving cell during the SI reading gap;
• means for updating at least one tracking loop for a downlink based on the neighbor cell during the SI reading gap;
• and
• means for maintaining capability to transmit on the uplink to the serving cell by the UE during the SI reading gap such that the UE has the capability to transmit on the uplink to the serving cell and receive the system information on the downlink from the neighbor cell during the SI reading gap.

An apparatus for wireless communication, comprising:

• a memory unit;
• and
• at least one processor coupled to the memory unit, the at least one processor being configured:
• to suspend reception of downlink transmission from a serving cell by a user equipment (UE) during a system information (SI) reading gap,
• to receive system information from a neighbor cell by the UE during the SI reading gap,
• to skip updating at least one tracking loop for an uplink based on the serving cell during the SI reading gap,
• to update at least one tracking loop for a downlink based on the neighbor cell during the SI reading gap, and
• to maintain capability to transmit on the uplink to the serving cell by the UE during the SI reading gap such that the UE has the capability to transmit on the uplink to the serving cell and receive the system information on the downlink from the neighbor cell during the SI reading gap.

A computer program product, comprising:

• a non-transitory computer-readable medium comprising:
• code for causing at least one computer to suspend reception of downlink transmission from a serving cell by a user equipment (UE) during a system information (SI) reading gap,
• code for causing the at least one computer to receive system information from a neighbor cell by the UE during the SI reading gap,
• code for causing the at least one computer to skip updating at least one tracking loop for an uplink based on the serving cell during the SI reading gap;
• code for causing the at least one computer to update at least one tracking loop for a downlink based on the neighbor cell during the SI reading gap;
• and
• code for causing the at least one computer to maintain capability to transmit on the uplink to the serving cell by the UE during the SI reading gap such that the UE has the capability to transmit on the uplink to the serving cell and receive the system information on the downlink from the neighbor cell during the SI reading gap.

A serving cell configured for wireless communication, comprising:

• a memory unit;
• and
• at least one processor coupled to the memory unit, the at least one processor being configured:
• to estimate system information (SI) reading gaps for a user equipment (UE) to read system information from at least one neighbor cell when the serving cell is unaware of when the UE will read the SI from the at least one neighbor cell based on the SI reading gaps autonomously selected by the UE, and
• to communicate with the UE based at least in part on the estimated SI reading gaps.
