Abstract
In a mobile device for wireless communication capable of communicating on multiple radio access technologies (RATs), cell selection may be improved by reusing cell measurements for inter-RAT cell selection. This will reduce the number of cell measurements taken and improve mobile device performance. A time threshold may be used to instigate new cell measurement to prevent cell measurement data from being outdated.
Claims20
A method for wireless communication, comprising:
- performing a signal measurement of a first radio access network at a first time following a paging occasion of the first radio access network;
- performing a signal measurement of a second radio access network at a second time following a paging occasion of the second radio access network, the paging occasion of the second radio access network occurring after the first time;
- and
- performing cell reselection using the signal measurement of the first radio access network and the signal measurement of the second radio access network.
A user equipment configured for wireless communication, the comprising:
- means for performing a signal measurement of a first radio access network at a first time following a paging occasion of the first radio access network;
- means for performing a signal measurement of a second radio access network at a second time following a paging occasion of the second radio access network, the paging occasion of the second radio access network occurring after the first time;
- and
- means for performing cell reselection using the signal measurement of the first radio access network and the signal measurement of the second radio access network.
A computer program product, comprising:
- a non-transitory computer-readable medium having program code recorded thereon, the program code comprising:
- program code to perform a signal measurement of a first radio access network at a first time following a paging occasion of the first radio access network;
- program code to perform a signal measurement of a second radio access network at a second time following a paging occasion of the second radio access network, the paging occasion of the second radio access network occurring after the first time;
- and
- program code to perform cell reselection using the signal measurement of the first radio access network and the signal measurement of the second radio access network.
A user equipment configured for wireless communication, comprising:
- at least one processor;
- and
- a memory coupled to said at least one processor,
- wherein said at least one processor is configured:
- to perform a signal measurement of a first radio access network at a first time following a paging occasion of the first radio access network;
- to perform a signal measurement of a second radio access network at a second time following a paging occasion of the second radio access network, the paging occasion of the second radio access network occurring after the first time;
- and
- to perform cell reselection using the signal measurement of the first radio access network and the signal measurement of the second radio access network.
