    Abstract: Methods and apparatuses are presented to facilitate coexistence between multiple wireless communication protocols implemented by a wireless communication device, using a shared antenna, e.g., due to limitations resulting from a small form factor of the wireless communication device. The wireless communication device may determine whether communications according to a second protocol are causing performance of communications according to a first protocol to fall below a threshold level. If so, the wireless communication device may operate in a mode that favors communications according to the first protocol. If not, the wireless communication device may operate in a mode that favors communications according to the second protocol. For example, the mode that favors communications according to the first protocol may include temporarily implementing operations to remedy the poor performance of the communications according to the first, e.g., periodically, until the performance of the communications according to the first protocol recovers.

    Abstract: A network reselection procedure, of a wireless communication device, that occurs following a network detachment event, such as a device sleep event or a device power savings mode event. The wireless communication device attempts to acquire a first wireless network to which the wireless communication device was most recently attached, immediately preceding the network detachment event. Then, in response to an unsuccessful acquisition of the first wireless network, the wireless communication device attempts an alternate network acquisition utilizing a Most Recently Used List (MRUL) that is stored at the wireless communication device and includes information about one or more frequency bands allocated to a primary service provider with which the wireless communication device is affiliated. After determining whether the alternate network acquisition attempt was successful, the wireless communication device attaches to a second network and stores information associated with the second network.

    Abstract: Improving transmission control protocol (TCP) uplink performance of a wireless user equipment (UE) device which multiplexes radio resources between multiple radio access technologies (RATs). Radio control may be provided to a radio resource control (RRC) entity that operates according to a first RAT at a first time. The first RAT may utilize TCP packet-switched (PS) communications. As a second time, radio control may be provided to an RRC entity that operates according to a second RAT which utilizes circuit-switched communications in order to check for paging messages. Radio control by the first RAT's RRC entity may be suspended while radio control is provided to the second RAT's RRC entity. An indication that radio control by the first RAT's RRC entity is suspended may be provided to a TCP entity that operates according to the first RAT. The TCP entity may suspend an uplink retransmission timer in response to the indication.

    Abstract: In order to reduce the time delay when transitioning between different communication protocols used to communicate information via a cellular-telephone network, an electronic device (such as a cellular telephone) may only partially disable a software stack associated with a current communication protocol. In particular, after receiving an indicator that there is a message to be communicated using a second communication protocol while the electronic device is currently configured to communicate using a first communication protocol, the electronic device may disable a portion of a software stack associated with the first communication protocol and may enable a software stack associated with the second communication protocol. Then, the electronic device communicates the message using the second communication protocol. Next, the electronic device: may disable the software stack associated with the second communication protocol and may enable the portion of the software stack associated with the first communication protocol.

    Abstract: Enabling receive diversity based on detecting incorrect paging message length. A paging channel may be monitored. An indication of a paging message may be received on the paging channel. The paging message may include a message length field indicating a message length of the paging message. The message length field of the paging message may be received on the paging channel and decoded. It may be determined that the message length indicated in the message length field is incorrect. Receive diversity may be enabled for at least one subsequent paging occasion in response to determining that the message length indicated in the message length field is incorrect.
