Abstract: A control circuit determines that a wireless portable electronic device currently being serviced via licensed wireless spectrum should also be served via unlicensed wireless spectrum and then transmits a Radio Resource Control (RRC) message to cause the wireless portable electronic device to connect to a network node operating in the unlicensed wireless spectrum. By one approach this control circuit comprises an Evolved Node-B base station in a Long Term Evolution (LTE) Radio Access Network (RAN) and the network node operating in the unlicensed wireless spectrum comprises an 802.11-compatible wireless local area network node.

Abstract: Systems and methods to request system information are provided. In some aspect, a user equipment (UE) transmits a request for on-demand system information. The UE transmits a challenge response for authentication of the request for the on-demand system information. The UE receives the on-demand system information after the request for the on-demand system information is authenticated based on the challenge response.

Abstract: Method and systems for managing a communication link. One or more indicators of an expected service interruption associated with a communication link is determined. The communication link may be a link between a relay and a communication target and/or a link between the relay and a user equipment (UE). In response, the UE initiates one or more actions to reduce or avoid the expected service interruption.

Abstract: A method for transmitting a scheduling request includes receiving, at a relay UE and from a remote UE, a sidelink control information. The relay UE is within a coverage area of a base station. The remote UE is outside of the coverage area. The relay UE is configured to relay transmissions from the remote UE to the base station, and the sidelink control information indicates a future transmission of a data packet over a sidelink channel. A scheduling request is transmitted to a base station. A scheduling grant that indicates an uplink resource is received from the base station. A data packet over the sidelink channel is received from the remote UE.

Abstract: In some examples, a device sends first information to a service, the first information comprising location information of the wireless device, and receives, from the service, assistance information that is based on the first information. The device performs initial access of a wireless access network using the assistance information to achieve power saving at the wireless device, and transmits second information to the service over the wireless access network node.

Abstract: A channel sharing method includes determining a starting time for transmission on an LAA-LTE channel. A length of a hybrid preamble is determined based on the starting time and a predetermined transmission time boundary. Subsequent to determining the length of the hybrid preamble, the hybrid preamble having the determined length is transmitted. Subsequent to the hybrid preamble, a Long Term Evolution (LTE) signal is transmitted.

Abstract: Some aspects of what is described here relate to systems, devices, and computer-implemented methods for capturing data related to a mobile device in a wireless network. In one example, a method may include receiving, at a mobile device, data capture configuration information from a wireless network, the data capture configuration information indicating a data type to be captured from the mobile device in an off-network environment. Thereafter, in response to detecting the off-network environment at the mobile device, a data element is stored in a local memory of the mobile device. The data element corresponds to the data type indicated by the data capture configuration information. The data element is sent to the wireless network, for instance, when the mobile device has access to the wireless network.

Abstract: A method for allocating resources for device-to-device transmission between two or more user equipment (UEs) includes transmitting, from a first UE to a second UE, a resource allocation configuration for device-to-device communications. A resource request for a device-to-device transmission is received from the second UE. In response to the resource request, a resource for the device-to-device transmission is selected at the first UE. A resource grant is transmitted to the second UE. The resource grant identifies the selected resource. A device-to-device transmission is received from the second UE over the selected resource.
