A user device (e.g., a mobile phone, user equipment (UE), a dual subscriber identity module (SIM) dual standby (DSDS) device, a multi-SIM multi-standby device (MSMS) device, a mobile device, a smart device, laptop, tablet, computing device, etc.) may dynamically determine configurations for preferred and/or offload networks and optimally switch connections between service provider networks.

Methods and systems for switching between service provider networks

A base station may sense, on a cell using unlicensed spectrum, that the unlicensed spectrum is available for transmission. The base station may transmit, after sensing that the unlicensed spectrum is available, consecutive subframes. Each subframe may include a physical downlink control channel and a physical downlink shared channel.

Wireless operation in unlicensed spectrum

A method and apparatus are described. A method includes determining whether the apparatus is in a coverage enhancement (CE) mode or a non-CE mode. The method further includes receiving a CE-system information block (CE-SIB) on a physical downlink shared channel (PDSCH) based on at least one of a known location or at least one known parameter for the CE-SIB, on a condition that the WTRU is determined to be in the CE mode.

Method and apparatus for system information block (SIB) acquisition for wireless transmit/receive units (WTRUS) in non-CE and coverage enhanced (CE) modes

A wireless transmit/receive unit (WTRU) receives first timing advances and first power control commands from a first eNodeB and second timing advances and second power control commands from a second eNodeB and transmits, to the first eNodeB, a first physical uplink control channel using a first uplink component carrier. The first physical uplink control channel has a first timing adjusted by the first timing advances but not by the second timing advances and a first power level adjusted by the first power control commands but not by the second power control commands. The WTRU transmits a second physical uplink control channel using a second uplink component carrier. The second physical uplink control channel has a second timing adjusted by the second timing advances but not by the first timing advances and a second power level adjusted by the second power control commands but not by the first power control commands.

Method and apparatus for enhancing cell-edge user performance and signaling radio link failure conditions via downlink cooperative component carriers

A method and apparatus are described for supporting a two-stage device-to-device (D2D) discovery using a D2D interworking function (IWF). A D2D IWF component may be configured to perform mapping between an application running on an application server and a third generation partnership project (3GPP) network, and provide a set of application programming interfaces (APIs) to allow discovery to be provided as a service to D2D applications. An application identifier may be mapped to a 3GPP identifier. Further, a method and apparatus are described for performing client-server discovery. A first wireless transmit/receive unit (WTRU) may be configured for a listen-only operation, and a second WTRU may be configured to transmit beacons. The first and second WTRUs may perform a radio access network (RAN) discovery procedure at an access stratum (AS) layer. A method and apparatus for performing charging for D2D service using a D2D IWF are also described.

Method and apparatus for supporting proximity discovery procedures

This disclosure includes a method, alone or in combination with other methods or steps described herein. The method may include defining, based on a multipath option and an identifier, a first connection with user equipment according to a first network provider over a path of a first network that comprises packet-switched signaling. The method may include defining, based on the identifier, a second connection with the user equipment according to a second network provider over a path of a second network that comprises the packet-switched signaling. The method may include receiving first data over the path of the first network and second data over the path of the second network. The method may include sending a combination of the first data and the second data to an application server. The method may include receiving, based on the combination, a response. The method may include sending the response to the user equipment.

Diverse pathway integration

A wireless transmit/receive unit (WTRU) may receive a first scheduling assignment that includes an indication of one or more first resources and an indication of a first priority for a first sidelink data transmission from another WTRU. The first WTRU may determine to send a second sidelink data transmission associated with a second priority that is lower than the first priority. The first WTRU may determine a signal strength associated with the first scheduling assignment and may select one or more resources for sending the second sidelink data transmission. The first WTRU may determine that one or more first resources are available for transmission of the second sidelink data transmission based on the signal strength associated with the first scheduling assignment being below a threshold. The first WTRU may send a second scheduling assignment including an indication of the selected one or more resources for the second sidelink data transmission.

Device-to-device (D2D) pre-emption and access control

Systems, methods, and instrumentalities are disclosed to manage interference caused by D2D communications. A wireless transmit receive unit (WTRU) may include a processor. The processor may be configured to perform one or more of the following. The processor may determine to send information using a device-to-device transmission via a resource pool from a plurality of resource pools. Each resource pool may be associated with a range of reference signal receive power (RSRP) values. The processor may determine a RSRP measurement of a cell associated with the WTRU. The processor may select a resource pool from the plurality of resource pools based on the RSRP measurement of the cell. The RSRP measurement of the cell may be within the range of RSRP values associated with the selected resource pool. The processor may send the information using the selected resource pool.

Resource selection for device to device discovery or communication

Methods and apparatus for changing cell range coverage are disclosed. A wireless transmit/receive unit (WTRU) may include circuitry configured to transmit subframes of radio frames using a physical uplink shared channel (PUSCH), where the subframes are divided into first and second sets. The circuitry may include a first power control loop utilized for the first set of subframes and a second power control loop utilized for the second set of subframes. The first power control loop may set transmission power levels for transmission over the PUSCH for the first set of subframes, and the second power control loop may set transmission power levels for transmission over the PUSCH for the second set of subframes. The circuitry may be configured with a first physical uplink control channel (PUCCH) for a first eNodeB and a second PUCCH for a second eNodeB to simultaneously communicate with the first and the second eNodeBs.

Method and apparatus for data-splitting transmission from multiple sites

Methods and apparatus for performing device-to-device (D2D) discovery are described. A service discovery process may include a discoverable device (e.g., a wireless transmit/receive unit (WTRU)) sending a discovery request, over a wireless connection, for a radio resource for the purpose of performing a transmission for radio frequency (RF) proximity detection for a given service. The WTRU may receive a discovery response including a configuration for RF proximity detection from a network, which configuration may be associated to the service. The configuration for RF proximity may be received by dedicated signaling, (e.g., physical downlink shared channel (PDSCH)), in particular for a discoverable WTRU. The configuration for RF proximity may be received on a broadcast channel, (e.g., a discovery shared channel (DISCH)), in particular for a monitoring WTRU, and may include one or more service identities, each associated with an RF proximity detection configuration, or a validity information and a measurement configuration.

Method and apparatus for performing device-to-device discovery

Methods, apparatuses and systems for user-plane congestion management are provided. Among these method, apparatuses and systems is a method, implementable by a base station (and/or a serving gateway), for mitigating user plane congestion. The method may include sending a congestion indication to a core network; receiving a general packet radio system (GPRS) tunneling protocol (GTP) packet including an first internet protocol (IP) packet associated with a first flow within a bearer; obtaining, from a header of the GTP packet, an indicator indicative of a priority of the IP packet, wherein the indicator was inserted into the header of the GTP packet by the core network responsive to the congestion indication; and dropping any of the GTP packet and the first IP packet on condition that a priority of a second IP packet associated with second flow within the bearer takes precedence over the priority of the first IP packet.

User-plane congestion management

Current wireless networks do not allow machine type communication (MTC) devices to have long discontinuous reception (DRX) cycles or sleep lengths. A long DRX cycle may allow MTC systems and devices to operate with much longer DRX/Sleep cycles/periods. This may facilitate the MTC operations for infrequent system access or infrequent system reaching (e.g. paged once in a week) with no or low mobility and may allow MTC devices to sleep for a long time with low power consumption.

Methods and apparatus for handling MTC long DRX cycle/sleep lengths
