Abstract: Methods are proposed by which a gNB may provide the terminal with multiple measurement gap configurations, each configuration including at least a measurement gap length. Each measurement gap configuration may be linked to a measurement object (with possibly multiple measurement gap configurations defined for one and the same measurement object). The provided measurement gap configurations may replace a measurement configuration information element employed in an LTE wireless communication system (in which case there is no default configuration); alternatively the terminal has a default measurement gap configuration, each measurement object optionally having its own measurement gap configuration which replaces the default configuration. The terminal may be provided with a measurement gap configuration list which indicates the plurality of measurement gap configurations, and a measurement identity list including measurement identities with mappings between the two.

Abstract: The invention provides for association of data streams (and/or logical channels) with individual carriers (cells), and independent buffer status reporting per carrier for terminals with more than one uplink carrier configured. In a “Small Cell” scenario for 3GPP LTE, a terminal may be simultaneously served by a macro cell and one or more small cells. These may operate at different frequencies, have different traffic loading and support different QoS (Quality of Service). The invention allows independent control of traffic on the uplinks to the macro cell and the small cells, which can be used to optimize the user experience in relation to the available resources at any given time/location, and allows particular data to be routed via particular cells.

Abstract: A data signal is transmitted in a wireless communication system from a primary station to a secondary station. The data signal comprising a medium access control header (MAC-hs header) and a protocol data unit associated with the medium access control header.

Abstract: A User Equipment (10) in a wireless communication network reports measurements or selects cells based on the EMF exposure to one or more persons in those cells, estimated to result on the uplink (UL) and/or downlink (DL) due to the UE's use of those cells. The network sends indications to the UE, in order to allow the UE to understand the EMF impact generated when the UE is connected to certain cells. For the downlink, these indications may include an EMF impact indicator or a UL beamforming reception capability indicator. For application to LTE, a new event triggered UE measurement reporting criterion is proposed to allow the UE to report measurements based on a new EMF related metric and to trigger measurement reports with regards to the EMF impact. The new EMF-based measurement reports allow the cell selection/reselection process to take into account minimization or optimization of the EMF impact on the environment.

Abstract: A network which allows the transmission of small data packets after reading System Information. The network can control a cell to allow access from devices (12) using an extended coverage mode, ECM, outside the normal coverage area of the cell. Initial access from devices in the extended cell coverage area can be scheduled (S104, S110) with the use of a pre-defined scheduled time for the devices to access the cell. A transmission of a schedule for ECM operation to the devices (12) that are using the ECM is provided (S144) after an ECM capable device has been moved from idle to connected mode for the first time, and can be updated (S146) at every scheduled opportunity when the device subsequently moves to connected mode. Additionally, embodiments of the present invention provide a modified RACH procedure (S122, S128, S134, S140) to be followed by devices (12) taking advantage of the ECM.

Abstract: In a wireless communication system providing a plurality of cells (Cell A, Cell B), the cells broadcast indications related to performance. At least one of the cells (Cell A) is a serving cell for a secondary station (10), and at least one other cell (Cell B) is not a serving cell. The secondary station (10) computes performance metrics for detected ones of the cells. Based on the values of the performance metrics, the secondary station (10) reports measurement/metrics for one or more cells to a primary station (20) providing a serving cell for the secondary station (10). In this way the primary station (20) can know the amount of available resources in each cell suitable for handover, and can make a better handover choice for the primary station (10).

Abstract: A communication system, such as UMTS, comprises a scheduler (12) in a first station (PS) which is able to control a user equipment (UE1, UE2). The scheduler when operating in a data transmission mode, such as HSUPA (High-Speed Uplink Packet Access) controls the user equipment with combinations of absolute grants (AG) and relative grants (RG). The relative grants serve to adapt a transmission parameter relative to a reference value. The reference value for the relative grant is selected dependent on a property of one or more of the grants. Such a property may comprise the absolute grant being an all process grant or a single process grant.
