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.

Network architecture, methods, and devices for a wireless communications network

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.

Adapting maximum allowed CCA failures based on single occasion periodicity

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.

Communication nodes and methods for relative positioning of wireless communication devices

Methods and apparatus in a fifth-generation wireless communications network, including an example method, in a wireless device, that includes determining a reporting quality threshold for a parameter related to channel state information (CSI); performing a measurement for each of a plurality of beams from a first predetermined set of beams for evaluation; evaluating the measurement for each of the plurality of beams against the reporting quality threshold; discontinuing the performing and evaluating of measurements in response to determining that the reporting quality threshold is met for one of the beams, such that one or more beams in the first predetermined set of beams are not measured and evaluated; and reporting, to the wireless communications network, CSI for the one of the beams.

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.

Adapting operations in flexible allocation slots partially overlapping with measurement gaps

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

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.

Optimization of automatic gain control for narrow bandwidth operation

One or more embodiments herein relate to a method for an uplink transmission timing adjustment in a wireless communication device served by a network node and configured to operate in a coverage enhancement mode. The coverage enhancement mode comprises a repetitive transmission of a first uplink signal during a first repetition period. The method comprises determining a change in a downlink timing (), determining whether the first repetition period is ongoing (); and in response to the change in the downlink timing and the first repetition period being ongoing, performing an adjustment of an uplink transmission timing outside the first repetition period ().

Uplink transmission timing control

According to certain embodiments, a method () by a wireless device () includes receiving information relating to a Narrowband Secondary Synchronization Signal (NSSS) transmit diversity scheme. The information indicates a number of NSSS occasions that use different NSSS transmit diversity configurations. Based on the NSSS transmit diversity scheme, at least one measurement is performed across NSSS occasions.

Explicit measurement definition

A wireless device is configured to receive an activation command that commands the wireless device to activate a serving cell. The wireless device is configured to activate the serving cell within a maximum delay since receiving the activation command. The maximum delay depends on whether there is at least one other serving cell already activated for the wireless device in the same frequency band as that in which the serving cell is to be activated.
