Single Antenna Sharing For Multiple Wireless Connections

摘要

A wireless device includes: a first radio and first transceiver configured to transmit and receive according to a first radio access technology; a second radio and second transceiver configured to transmit and receive according to a second radio access technology; a first antenna and a second antenna connected to the first radio and the second radio; a switch; and a control unit configured to control the switch to configure connections of the first and second antennas to the first and second radios. The control unit is configured to control the switch to disconnect the second radio from the second antenna in response to a receiving, by the second radio through the second antenna, a signal that is below a predetermined threshold, and to connect the second radio to the first antenna during a wakeup period of the second radio.

主权项

1. A method for antenna selection in a wireless device having a first radio associated with a first radio access technology and a second radio associated with a second radio access technology different from the first radio access technology, wherein the first and second radios each comprise a base band processor, the method comprising:
determining whether a signal received through an antenna assigned to the first radio falls below a predetermined threshold; and in response to determining that the received signal is below the predetermined threshold:
setting the first radio in an idle mode;configuring a new receive path associated with the first radio, wherein the new receive path utilizes an antenna assigned to the second radio;
detecting a wakeup period associated with the first radio access technology; andselecting the new receive path for receiving signals from a network associated with the first radio access technology in response to detecting the wakeup period associated with the first radio access technology.
