Methods performed by a wireless device and a base station for adapting maximum allowed Clear Channel Assessment (CCA) based on operational occasion periodicity are provided. In examples disclosed herein, a wireless device is configured to determine an operational occasion periodicity of a signal that is subject to CCA. Accordingly, the wireless device can determine an association at least between the determined operational occasion periodicity and a maximum number of allowed CCA failures for communicating the signal. The wireless device can then perform one or more operational tasks based on the determined maximum number of allowed CCA failures. By determining the maximum number of allowed CCA failures, the wireless device can obtain information about downlink CCA failures and use the obtained information for adapting measurements procedures in serving cell operational tasks.

A server node and method therein for assisting a first wireless communication device and a second wireless communication device to seek each other in a wireless communication network are disclosed. The server node inquires positioning and movement information of the first and second devices and obtains information on a relative position between the first and the second devices. The server node then sends instructions to at least one of the first and second devices based on the information on the relative position.

Systems and methods are disclosed herein for operational tasks to be performed in slots that are partially overlapped by measurement gaps in a wireless communication system. Embodiments of a method performed by a wireless device and corresponding embodiments of a wireless device are disclosed. In some embodiments, a method performed by a wireless device for performing scheduled communications operations for a serving cell comprises determining a communication slot that is partially overlapped by a measurement gap, the communication slot being associated with a serving cell of the wireless device. The method further comprises identifying a scheduled operational task which can be carried out in a non-overlapped portion of the communication slot, the non-overlapped portion of the communication slot being a portion of the communication slot not overlapped by the measurement gap. The method further comprises performing the scheduled operational task in the non-overlapped portion of the communication slot.

A method for performing measurements in a wireless device is provided. The method comprises: storing a plurality of received measurement configurations, which are linked to each other; applying a first measurement configuration from the plurality of measurement of configurations; and determining whether to apply a second measurement configuration from the plurality of measurement configurations based on the first measurement configuration.

Methods for activation/deactivation of measurement configurations via linkage

A method and apparatus for an incentive and measurement coordination function in a mobile communications network cooperating with a gaming server, advertisement server or similar node or function to attract smartphone users, or users of other devices, to geographical areas where there is a need for coverage measurements. In particular, user equipments may be directed or steered towards areas where network related measurements are necessary (e.g. RSRP) and which are relevant e.g. for network planning. In this manner, an operator may reduce the amount of, or completely eliminate, drive tests (minimization of drive tests, MDT). Users may get incentives (e.g. vouchers, prizes, etc.) in order to move to areas where such measurements are necessary.

Directing devices for coverage measurement purposes

Methods and apparatus in a fifth-generation wireless communications, including an example method, in a wireless device, that includes receiving a downlink signal comprising an uplink access configuration index, using the uplink access configuration index to identify an uplink access configuration from among a predetermined plurality of uplink access configurations, and transmitting to the wireless communications network according to the identified uplink access configuration. The example method further includes, in the same wireless device, receiving, in a first subframe, a first Orthogonal Frequency-Division Multiplexing (OFDM) transmission formatted according to a first numerology and receiving, in a second subframe, a second OFDM transmission formatted according to a second numerology, the second numerology differing from the first numerology. Variants of this method, corresponding apparatuses, and corresponding network-side methods and apparatuses are also disclosed.

The gain of an amplifier in a receiver operating in a cellular communication system is controlled by determining one or more gain variability metrics, which are then used to produce first and second threshold values. A frequency difference between a current carrier frequency and a target carrier frequency is ascertained and then compared to the threshold values. Target gain setting production is based on comparison results: If the frequency difference is larger than the first threshold, a first automatic gain control algorithm is performed; if the frequency difference is smaller than the first threshold and larger than the second threshold, a second automatic gain control algorithm is performed, wherein the second automatic gain control algorithm uses a current gain setting as a starting point; and if the frequency difference is smaller than both the first and second thresholds, the current gain setting is used as the target gain setting.
