Embodiments are described herein for selective joinder of wireless cells by machine-type communication (MTC) user equipment (UE). An MTC UE may detect a plurality of wireless cells, each provided by an evolved Node B (eNB). The MTC UE may detect eNB categories associated with individual wireless cells of the plurality of wireless cells, and may identify one or more wireless cells of the plurality of detected wireless cells on which MTC traffic is permitted based on the associated eNB categories. The MTC UE may selectively join a wireless cell of the one or more identified wireless cells based on a cell selection criterion. Additionally, an eNB may provide a wireless cell and provide, to an MTC UE, an MTC policy that identifies a circumstance under which the eNB will permit MTC traffic. The eNB may be configured to selectively serve the MTC UE based on the MTC policy.

A method and wireless transmit receive unit (WTRU) are disclosed that is configured to perform cell reselection to another cell when the WTRU is in a CELL_FACH state using an Enhanced-Dedicated Channel (E-DCH). The cell reselection is based on internal measurements by the WTRU. Alternatively, the cell reselection can be WTRU based on the WTRU measurements reported to the network.

A disclosure of the present specification provides a method for establishing a packer data network (PDN) connection by a user equipment (UE). The method may comprise the steps of: transmitting a session initiation protocol (SIP)-based request message for requesting sending of a voice over LTE (VoLTE) call through a first type PDN connection; receiving, from a network node, a message including information directly or indirectly indicating that there is a problem in the first type PDN connection, instead of a normal response message to the SIP-based request message; determining to change the PDN type from the first type to a second type, on the basis of the information in the received message; and transmitting, to a mobility management entity (MME), a PDN connection request message including information on the changed second type.

A radio terminal (12) transmits, to a radio access network (RAN) node (11) in a radio access network (RAN), an indication indicating whether a measurement gap for inter-bandwidth part (BWP) measurement among BWPs included in a plurality of downlink BWPs is required. The downlink BWPs are included within one system bandwidth. Further, the radio terminal (12) receives, from the RAN node (11), a measurement configuration including a measurement gap configuration for one or more BWPs included in the downlink BWPs. It is thus, for example, possible to allow a radio terminal to be configured with a proper measurement gap for inter-BWP measurement within one carrier bandwidth.

Interruptions in communication due to user equipment (UE) handovers (HO) are signaled from the mobile communication network to the traffic source. For ultra-low latency and reliable communication, the signaling of HO start and completion notifications prevents retransmissions of in-flight packets by the traffic source, eliminating additional delays and inefficiencies. Signaling can be implemented by a network element, by a network element in conjunction with a smart traffic handler between the network and the traffic source (e.g., applications) and by a UE having at least two different radio interfaces.

Systems and techniques relating to wireless communications are described. A transmitter for a wireless local area network (WLAN) identifies a channel bonding mode out of a number of channel bonding modes. The channel bonding mode includes two or more available channels used by the transmitter for data transmission in the WLAN, and the two or more available channels indicating at least one busy channel not used by the transmitter for data transmission. The channel bonding mode is signaled to a receiver using a bandwidth field of a legacy signal field that is duplicated across respective channels used in the WLAN, the legacy signal field being in a preamble portion of a frame. The frame is transmitted to the receiver, wherein the frame includes a data portion of the frame that occupies the two or more available channels according to the channel bonding mode.

A first computer that includes a processor and memory storing instructions executable by the processorthe processor is programmed to: establish a satellite link between a satellite terminal and the first computer, the link comprising at least one radio access bearer (RAB); receive a rejection message from a second computer indicating that the second computer refuses to accept a terminal handover; and in response to receiving the rejection message, transmit to the second computer a pending handover request message comprising an indication of a link quality of the at least one RAB.
