Abstract
A user equipment terminal (UE) performs cell search in a wireless network. The UE determines a search pattern based on statistics of search trials performed at one or both of a location and time in a recurrent time cycle. The search pattern includes a sequence of alternating search durations and non-search durations for a configurable number of searches. Furthermore, the search pattern includes the search durations or the non-search durations that increase, decrease, or no-change according to probability derived from the statistics. The UE performs the cell search according to the search pattern.
Claims20
A method for a user equipment terminal (UE) to perform cell search in a wireless network, comprising:
- determining a search pattern based on statistics of search trials performed at one or both of a location and time in a recurrent time cycle,
- wherein the search pattern includes a sequence of alternating search durations and non-search durations for a configurable number of searches, and
- wherein the search pattern includes the search durations or the non-search durations that increase, decrease, or no-change according to probability derived from the statistics;
- and
- performing the cell search according to the search pattern.
An apparatus for wireless communication, the apparatus being a user equipment terminal (UE), comprising:
- antenna circuitry;
- a memory;
- and
- processing circuitry coupled to the memory and operative to perform cell search, the processing circuitry further operative to:
- determine a search pattern based on statistics of search trials performed at one or both of a location and time in a recurrent time cycle,
- wherein the search pattern includes a sequence of alternating search durations and non-search durations for a configurable number of searches, and
- wherein the search pattern includes the search durations or the non-search durations that increase, decrease, or no-change according to probability derived from the statistics;
- and
- perform the cell search according to the search pattern.
