Abstract

A user equipment (UE) may communicate over a first wireless wide area network (WWAN). The first WWAN may be supported by a first subscriber identity module (SIM) of the UE. The UE may also communicate simultaneously over a second WWAN supported by a second SIM. The UE may process the second WWAN communication with a portion of a WWAN module and a portion of a wireless local area network (WLAN) module.

First claim

What is claimed is:

1 . A method for wireless communication, comprising:
receiving, via a first antenna associated with a first radio access technology, a first signal corresponding to the first radio access technology; receiving, via a second antenna associated with the first radio access technology, a second signal corresponding to the first radio access technology; and processing the second signal by at least one component associated with a second radio access technology, the second radio access technology being different from the first radio access technology.

2 . The method of claim 1 , further comprising:
processing the first signal by at least one component associated with the first radio access technology.

3 . The method of claim 1 , wherein the first radio access technology supports a first subscriber identity module (SIM) of the UE, and the second radio access technology supports a second SIM of the UE.

4 . The method of claim 1 , wherein the first radio access technology is associated with a wireless wide area network (WWAN).

5 . The method of claim 1 , wherein the second radio access technology is associated with a wireless local area network (WLAN).

6 . The method of claim 1 , further comprising:
processing the second signal using a radio frequency (RF) front end component associated with the first radio access technology.

7 . The method of claim 6 , further comprising:
routing the second signal from the RF front end component associated with the first radio access technology to the at least one component associated with the second radio access technology.

8 . The method of claim 7 , further comprising:
routing the second signal from the at least one component associated with the second radio access technology to a baseband component associated with the first radio access technology, wherein the at least one component associated with the second radio access technology is an analog component.

9 . The method of claim 1 , further comprising:
processing the second signal using an amplifier associated with the first radio access technology.

10 . The method of claim 1 , wherein the at least one component associated with the second radio access technology comprises a filter.

11 . The method of claim 1 , wherein the at least one component associated with the second radio access technology comprises a down-converter.

12 . The method of claim 1 , wherein the at least one component associated with the second radio access technology comprises an amplifier.

13 . The method of claim 1 , wherein the at least one component associated with the second radio access technology comprises an analog-to-digital converter.

14 . The method of claim 1 , wherein the second antenna is a diversity antenna associated with the first radio access technology.

15 . The method of claim 1 , further comprising:
receiving, via a third antenna associated with the second radio access technology, a third signal corresponding to the second radio access technology.

16 . The method of claim 15 , further comprising:
determining a first time for processing the second signal by the at least one component associated with the second radio access technology; and determining a second time for processing the third signal by the at least one component associated with the second radio access technology.

17 . The method of claim 15 , wherein the third signal is associated with Wireless Fidelity (Wi-Fi) communications.

18 . The method of claim 1 , wherein the first signal is associated with one of Long Term Evolution (LTE) communications or LTE-Advanced (LTE-A) communications.

19 . The method of claim 1 , wherein the second signal is associated with global system for mobile communications (GSM).

20 . A method for wireless communication, comprising:
transmitting, via a first antenna associated with a first radio access technology, a first signal corresponding to the first radio access technology; processing a second signal by at least one component associated with a second radio access technology, the second radio access technology being different from the first radio access technology; and transmitting, via a second antenna associated with the first radio access technology, the second signal corresponding to the first radio access technology.

21 . The method of claim 20 , further comprising:
processing the first signal by at least one component associated with the first radio access technology.

22 . The method of claim 20 , wherein the first radio access technology supports a first subscriber identity module (SIM) of the UE, and the second radio access technology supports a second SIM of the UE.

23 . The method of claim 20 , wherein the first radio access technology is associated with a wireless wide area network (WWAN).

24 . The method of claim 20 , wherein the second radio access technology is associated with a wireless local area network (WLAN).

25 . The method of claim 20 , further comprising:
routing the second signal from a baseband component associated with the first radio access technology to the at least one component associated with the second radio access technology, wherein the at least one component associated with the second radio access technology is an analog component.

26 . The method of claim 25 , further comprising:
routing the second signal from the at least one component associated with the second radio access technology to a radio frequency (RF) front end component associated with the first radio access technology.

27 . The method of claim 26 , further comprising:
processing the second signal using an RF front end component associated with the first radio access technology.

28 . The method of claim 20 , wherein the at least one component associated with the second radio access technology comprises a synthesizer.

29 . The method of claim 20 , wherein the at least one component associated with the second radio access technology comprises a filter.

30 . The method of claim 20 , wherein the at least one component associated with the second radio access technology comprises a digital-to-analog converter.

31 . The method of claim 20 , wherein the second antenna is a diversity antenna associated with the first radio access technology.

32 . The method of claim 20 , further comprising:
determining a first time for processing the second signal by the at least one component associated with the second radio access technology; and determining a second time for processing a third signal by the at least one component associated with the second radio access technology, the third signal corresponding to the second radio access technology.

33 . The method of claim 32 , further comprising:
transmitting, via a third antenna associated with the second radio access technology, the third signal during the second time for processing the third signal.

34 . The method of claim 32 , wherein the third signal is associated with Wireless Fidelity (Wi-Fi) communications.

35 . The method of claim 20 , wherein the first signal is associated with one of Long Term Evolution (LTE) communications or LTE-Advanced (LTE-A) communications.
