Abstract
An apparatus and a method are provided for selecting a receiver in a user equipment (UE). The method includes receiving, at the UE, a signal; determining, at the UE, a switch metric based on correlation metrics of a training sequence of the signal; comparing, at the UE, the switch metric with a threshold; and selecting, at the UE, one of a voice services over adaptive multi-user channels on one slot (VAMOS) receiver and a non-VAMOS receiver based on the comparing result.
Claims17
A method for selecting a receiver in a user equipment (UE), the method comprising:
- receiving, at the UE, a signal;
- generating a first correlation metric based on a correlation of a training sequence of the signal with a local training sequence for the UE in a voice services over adaptive multi-user channels on one slot (VAMOS) mode;
- generating a second correlation metric based on a correlation of the training sequence of the signal with a local training sequence for the UE in a non-VAMOS mode;
- determining a switch metric based on the first correlation metric and the second correlation metric;
- comparing, at the UE, the switch metric with a threshold;
- and
- selecting, at the UE, one of a VAMOS receiver and a non-VAMOS receiver based on the comparing result.
A user equipment (UE) comprising:
- at least one processor;
- and
- a memory including a computer executable program code, which when executed, controls the at least one processor,
- wherein the at least one processor is configured to:
- receive a signal;
- generate a first correlation metric based on a correlation of a training sequence of the signal with a local training sequence for the UE in a voice services over adaptive multi-user channels on one slot (VAMOS) mode;
- generate a second correlation metric based on a correlation of the training sequence of the signal with a local training sequence for the UE in a non-VAMOS mode;
- determine a switch metric based on the first correlation metric and the second correlation metric;
- compare the switch metric with a threshold;
- and
- select one of a VAMOS receiver and a non-VAMOS receiver based on the comparing result.
A computer program product comprising a computer executable program code recorded on a computer readable non-transitory storage medium, wherein the computer executable program code, when executed, causes a user equipment to:
- receive a signal;
- generate a first correlation metric based on a correlation of a training sequence of the signal with a local training sequence for the UE in a voice services over adaptive multi-user channels on one slot (VAMOS) mode;
- generate a second correlation metric based on a correlation of the training sequence of the signal with a local training sequence for the UE in a non-VAMOS mode;
- determine a switch metric based on the first correlation metric and the second correlation metric;
- compare the switch metric with a threshold;
- and
- select one of a VAMOS receiver and a non-VAMOS receiver based on the comparing result.
