Claims:1. A wireless device comprising:
a transmit chain;
a first holder for housing a first subscriber identity module (SIM);
a second holder for housing a second SIM; and
a processing block configured to:
receive concurrently a first sequence of sub-frames on the first SIM and a second sequence of sub-frames on the second SIM;
determine whether the first sequence of sub-frames and the second sequence of sub-frames are received in respective successive sub-frame intervals prior to a current interval; and
if the first sequence of sub-frames and the second sequence of sub-frames are received in successive sub-frame intervals prior to the current interval:
allocate a first sequence of successive sub-frame intervals to the first SIM to transmit using the transmit chain; and
allocate a second sequence of successive sub-frame intervals to the second SIM to transmit using the transmit chain.
, Description:Background
[001] Technical Field
[002] Aspects of the present disclosure relate generally to user equipment used in wireless telephone networks, and more specifically to scheduling acknowledgements to received sub-frames in multi-SIM user equipment using a shared transmit chain when receiving data continuously on each SIM (Subscriber Identity Module).

[003] Related Art
[004] Wireless user equipment (UE), or wireless devices in general, refer to instruments such as mobile phones using which users connect with mobile telephone networks on a wireless medium, as is well known in the relevant arts. In a common scenario, a UE interfaces with a base station of a mobile telephone network providing the corresponding user the facility of voice and data based services.
