Abstract: Measurement mode determination for narrowband internet of things devices There are provided measures for measurement mode determination for NB-IoT devices. Such measures exemplarily comprise receiving, by a NB-IoT device and from a serving network node (30), configuration information indicative of a measurement mode (e.g., Inband/Guard-band/Standalone) in relation to a neighbor cell, deriving said measurement mode of said neighbor cell from said configuration information, and measuring a reference signal of said neighbor cell based on said measurement mode.

Abstract: Various communication systems may benefit from taking appropriate measurements. For example, certain wireless communication systems may benefit from optimized user equipment measurements for fast cell access. A method can include receiving, at a user equipment, a configuration from a network to which the user equipment is connected. The configuration may include instructions to the user equipment regarding measurements with respect to detected cells. The method may also include performing the measurements according to the received configuration, and reporting the measurements to the network.

Abstract: Methods, apparatuses, and computer program products for uplink (UL) timing advance (TA) adjustment at beam switch are provided. A method may include, when it is determined that beam change or transmission configuration indication (TCI) state switch should occur for beam(s) originating from non-collocated source nodes, enabling assistance information relating to time difference for a UE. The method may include preparing timing adjustment prediction model(s) configured to predict a timing advance adjustment (TAA) or actual TA that should be applied by the UE at the beam change, using the at least one prepared timing adjustment prediction model to determine the TAA or the actual TA that should be applied by the UE at the beam change. The method may include signaling or assigning the TAA or the actual TA to the UE, or using the TAA to adjust for a UE autonomously adjusted TA value at the beam change.

Abstract: Systems, methods, apparatuses, and computer program products for conditional proactive discontinuous reception (DRX) measurement are provided. For example, a user equipment (UE) may be in a DRX active state (e.g., where the DRX is used) and configured to proactively measure for radio problems. Another example may relate to a network-controlled implementation where the serving network node (e.g., a base station (BS)) may signal the UE a condition and a configuration for the proactive DRX measurement. Another example may relate to a UE-controlled implementation for improving service unavailability using DRX operation. For example, the serving BS may signal, to the UE, proactive DRX measurement assistance information.

Abstract: Systems, methods, apparatuses, and computer program products for faster radio frequency (RF) activation are provided. One method may include transmitting by a network node, or receiving by a user equipment, a connection release message for the user equipment, wherein the connection release message comprises an indication for the user equipment to start measuring secondary cells after connection release. The method may then include during or immediately after connection setup or connection resume, receiving by the network node or transmitting by the user equipment, an indication of availability of measurements of the secondary cells.

Abstract: Methods and apparatus, including computer program products, are provided for MBSFN measurements. In one aspect there is provided a method. The method may include receiving, by a user equipment, measurement configuration information indicative of one or more first measurements to be performed on a first set of subframes and one or more second measurements to be performed on a second set of subframes, wherein the first set of subframes are associated with multicast broadcast mobile services and the second set of subframes are associated with non-multicast broadcast mobile services; and performing one or more measurements in accordance with the received measurement configuration information; and reporting one or more first measurement results for the one or more first measurements supplemented with one or more second measurement results for the one or more second measurements. Related apparatus, systems, methods, and articles are also described.

Abstract: Various communication systems may benefit from appropriate sharing of resources amongst multiple nodes. For example, certain wireless communication systems may benefit from using a single measurement gap for master node and secondary node measurements in a multi-radio-access-technology dual connectivity scenario, or similar scenarios. A method can include determining, by a first network node, that a gap pattern is existing in a second network node. The method can also include enquiring, by the first network node to the second network node, whether the gap pattern can be used for a new measurement. The method can further include configuring, by the first network node, a user equipment to perform the new measurement in the gap pattern, based on a response from the second network node to the enquiring.

Abstract: A method and apparatus for providing multi-beam downlink channel control procedures. The invention allows for power savings at a user device by indicating what states are to be used and/or indicating deactivation of receiver panels. This is accomplished, at least partially, through the use of a transmission configuration indication table based, at least partially, on measurements made by a user device and panel tags indicating the panels used to make those measurements. Determining optimal downlink and uplink beam selection is accomplished with reference to user device measurements and reporting.

Abstract: In the context of measurement configuration in the presence of multiple carriers, and in particular supplementary cells, LAA SCells, a method is provided to scale the measurement period that takes into account the capability of the UE to perform, for example by means of multiple searchers or increased buffer capacity, to measure multiple carriers simultaneously. The method comprises determining a scaled period (p) according to the following equation: p=pDMTC*min[n, ceiling(NCC/NCC_support)]; selecting respective selected occasions for each of NCC carriers out of occasions for measuring a respective reference signal, wherein the occasions occur with the predefined period (pDMTC), and the respective selected occasions occur with the scaled period (p); and inhibiting a measuring of a respective reference signal at occasions different from the respective selected occasions for each of the NCC carriers.
