Single antenna sharing for multiple wireless connections

A wireless device, comprising:

• a first radio comprising a base band processor associated with a first radio access technology;
• a second radio comprising a base band processor associated with a second radio access technology different from the first radio access technology;
• a processor coupled to the first radio and the second radio, wherein the processor is configured with processor-executable instructions to:
• receive, through an antenna assigned to the first radio, a signal from a network using the first radio access technology;
• determine whether the signal received through the 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:
• set the first radio in an idle mode;
• configure a new receive path associated with the first radio, wherein the new receive path utilizes an antenna assigned to the second radio;
• detect a wakeup period associated with the first radio access technology;
• and
• select the new receive path for receiving signals from the network using the first radio access technology in response to detecting the wakeup period associated with the first radio access technology.

• in response to determining that the received signal is below the predetermined threshold:
• means for setting the first radio in an idle mode;
• means for configuring a new receive path associated with the first radio, wherein the new receive path utilizes an antenna assigned to the second radio;
• means for detecting a wakeup period associated with the first radio access technology;
• and
• means for selecting the new receive path for receiving signals from the network using the first radio access technology in response to detecting the wakeup period associated with the first radio access technology.

A non-transitory processor-readable storage medium having stored thereon processor-executable instructions configured to cause a processor of 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, to perform operations comprising:

• receive, through an antenna assigned to the first radio, a signal from a network using the first radio access technology;
• determining whether the signal received through the 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;
• determining whether a wakeup period associated with the first radio access technology has started;
• and
• selecting the new receive path for receiving signals from the network using the first radio access technology in response to determining that a wakeup period associated with the first radio access technology has started.
