Optimized LTE MIB/SIB collection logic after LTE handover
A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus performs a handover from a source cell to a target cell. The apparatus determines a decoding timer value based on network conditions. The apparatus attempts to decode a MIB or a SIB from the target cell within a time after the handover corresponding to the decoding timer value. The apparatus triggers a radio link failure (RLF) when the MIB or the SIB is not decoded within the time corresponding to the decoding timer value.
1. A method of wireless communication, by a user equipment, comprising:
performing a handover from a source cell to a target cell;
determining that the target cell and the source cell are a same cell when the source cell and the target cell have a same cell frequency;
determining that Transmission Time Interval-Bundling (TTI-B) is enabled; and
refraining from decoding a master information block (MIB) message or a system information block message (SIB) of the target cell when it is determined that the target cell and the source cell are the same cell and that TTI-B is enabled.
2. The method of claim 1 , further comprising maintaining a voice over long term evolution call (VoLTE) using the MIB or SIB of the source cell after the handover to the target cell is performed.
3. The method of claim 1 , further comprising determining that the source cell and the target cell have a same cell identifier.
4. The method of claim 1 , wherein the determining that TTI-B is enabled comprises determining that a TTI-B flag is toggled.
5. An apparatus for wireless communication, comprising:
means for performing a handover from a source cell to a target cell;
means for determining that the target cell and the source cell are a same cell when the source cell and the target cell have a same cell frequency;
means for determining that Transmission Time Interval-Bundling (TTI-B) is enabled; and
means for refraining from decoding a master information block (MIB) message or a system information block message (SIB) of the target cell when it is determined that the target cell and the source cell are the same cell and that TTI-B is enabled.
6. The apparatus of claim 5 , further comprising means for maintaining a voice over long term evolution call (VoLTE) using the MIB or SIB of the source cell after the handover to the target cell is performed.
7. The apparatus of claim 5 , further comprising means for determining that the source cell and the target cell have a same cell identifier.
8. The apparatus of claim 5 , wherein the means for determining that TTI-B is enabled is configured to determine that a TTI-B flag is toggled.
