Abstract: Method and apparatus for supporting massive random access An access device configures resources for a proxy-based random access operation to the network and transmits an indication of the configured resources and of at least one identified support device and of a plurality of identified terminal devices to use the proxy-based random access operation, wherein the at least one support device is instructed by the indication to act as a proxy for the proxy-based random access operation. Then, the proxy-based random access operation can be enabled for the identified plurality of terminal devices via the at least one support device.

Abstract: A terminal device selects are source indicator to be used for non-scheduled access and transmits it to an access device of the network in the non-scheduled access. If it determines based on a response to the non-scheduled access, that it has selected the same resource indicator as another terminal device, it keeps the resource indicator but selects different physical random access channel occasions by setting a time offset for a retransmission with the selected resource indicator. An initial waiting time may be determined by the access device (e.g. based on a traffic amount on the access channel) and transmitted to the terminal device for setting the time offset. Also, a layer (2) error caused by a random access channel resource collision of terminal devices may be determined at the access device and a feedback indicating a non-acknowledgement for layer (2) may be transmitted to colliding terminal devices.

Abstract: According to an example embodiment, a method may include logging, by a user device in a wireless network, information related to a multiple-event conditional handover execution, wherein the multiple-event conditional handover execution is based on a joint evaluation of multiple events by the user device; and sending, by the user device, a report including at least a portion of the information.

Abstract: Configuration information including location and radio capabilities for first and second network nodes (for example, DeNB and RN respectively) are provided to register them to a spectrum access system (SAS). To establish a DeNB-RN backhaul link on a shared radio spectrum the DeNB sends the SAS a request for radio resources and authorization to transmit. The configuration information and/or the request indicates the DeNB and the RN belong to a backhaul system. The DeNB receives a grant for the radio resources and authorization, and broadcasts the authorization to the RN. The RN scans a broadcast channel while its receiver is active and its transmitter is inactive; detects the authorization to transmit, changes its transmitter from inactive to active, and transmits a reply to the DeNB's broadcast. The RN's reply to the DeNB's broadcast is used to establish the backhaul link.
