    Abstract: Methods and apparatus for transmitting extended service request messages in a congested network are described. An apparatus includes a timer, a receiver and a processor. The receiver receives a message that includes a timer value. The processor sets the timer based on the timer value, activates the timer, and attempts mobile-originated circuit switched fallback for an emergency call during a period that corresponds to the timer value and during which mobile-originated circuit switched fallback is otherwise prohibited.

    Abstract: A method and apparatus may be used to cancel a communication session. The apparatus may transmit a message that indicates a request to cancel the communication session. The apparatus may continue a Packet Switched (PS) session without performing an intersystem change. If the apparatus receives an intersystem change command, the apparatus may transmit a message to reject the intersystem change command, or it may ignore the intersystem change command.

    Abstract: A wireless transmit/receive unit (WTRU), supporting Long Term Evolution (LTE), to perform circuit switched (CS) fallback is provided. The WTRU may receive, via a packet switched (PS) evolved UMTS terrestrial radio access network (E-UTRAN), a paging message including an International Mobile Subscriber Identity (IMSI). The paging message may have a domain indicator indicating that the paging message is from a CS service. The WTRU may fallback to CS and subsequently use the IMSI.

    Abstract: A method and apparatus are described. A wireless transmit/receive unit (WTRU) generates data bits and piggybacked acknowledgement/non-acknowledgement (PAN) bits and generates a plurality of symbols based on the data bits and the PAN bits. Each symbol of the plurality of symbols represents a plurality of bits and has a least significant bit (LSB) position, and no PAN bits are present in the LSB position of each of the plurality of symbols. The plurality of symbols are transmitted.

    Abstract: A method for use in wireless transmit/receive unit (WTRU) which assesses both a first network and a second network to receive radio frames from each of the first network and the second network is disclosed. The method comprise: obtaining a first paging occasion (PO) as the first network's current PO and a second PO as the second network's current PO; determining whether there is a PO collision between the first PO and the second PO, on condition that there is the PO collision, selecting a network from the first network and the second network, and sending a request to the selected network; receiving, from the selected network, a collision avoidance parameter corresponding to the request; calculating a third PO for the selected network using the collision avoidance parameter, and using the third PO as the selected network's current PO.
