The network node assigns resources based at least in part on the priority level. The resources are used for D2D communication or cellular communication.

Abstract: A Device-to-Device, D2D, communication between a first wireless device (D1) served by a first base station (BS1) and a second wireless device (D2) served by a second base station (BS2), is supported by employing an assisting node (406) which cooperates with the first base station by creating a network code form (f(x1,x2)) of first data (x1) transmitted by the first wireless device and second data (x2) transmitted by the second wireless device. The assisting node then transmits the network coded form of the first and second data to the first base station, such that the first base station is able to determine the second data (x2) based on the received first data (x1) and the network coded form (f(x1,x2)), and to transmit the second data to the first wireless device. Thereby, the first wireless device is able to determine the second data more accurately by combining the second data transmitted by the second wireless device in the D2D communication and the second data x2 transmitted by the first base station.

Abstract: Method and radio access point for handling a two-way communication between a first wireless device and a second wireless device which are both served by the radio access point. A set of candidate transmission modes are available for use in the two-way communication. The radio access point obtains a mode-specific quality metric related to a predicted Signal to Interference and Noise Ratio, SINR, for each one of the candidate transmission modes, and selects one of the candidate transmission modes based on the obtained mode-specific quality metrics. The radio access point is thus able to select the transmission mode that has the best mode-specific quality metric in the set. The selected transmission mode is then applied for the two-way communication. Thereby, the most favourable transmission mode may be selected and used to provide satisfactory or even optimal performance.

Abstract: A system and method for enhanced support for handling of Closed Subscriber Groups (CSGs) and sharing of Radio Access Network (RAN) for home base stations and other small cells. An enhanced System Information (SI) structure indicates multiple CSG IDs and CSG Indications, thereby making it possible to support different CSG IDs and CSG Indications for every Public Land Mobile Network Identity (PLMN-ID) and also to support a PLMN-ID with multiple associated CSG IDs and CSG Indications. The enhanced SI makes it possible to have different CSG IDs for different operators, to have multiple CSG IDs for one operator (i.e., a single PLMN), and to selectively use the CSG concept for some PLMNs (as given by their respective CSG Indications), but not for all. A network of base stations (e.g., a RAN) thus can be effectively shared by multiple operators, leading to better cellular coverage, peak rates, and capacity.
