A method is disclosed herein for reducing energy consumption in a wireless device. A wireless device (e.g., a user equipment) can provide an indication to a network node (e.g., a base station) to indicate that the wireless device will prioritize energy consumption reduction over some network requirements (e.g., latency and/or scheduling flexibility requirements). Accordingly, the wireless device can perform certain power-saving actions to reduce energy consumption. The network node, upon receiving the indication from the wireless device, can perform certain network-related actions to assist the wireless device in reducing energy consumption. As a result, it is possible for the wireless device to reduce energy consumption and complexity, thus helping to prolong battery life in the wireless device.

Methods and devices for reducing UE energy consumption

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

Embodiments described herein provide methods and apparatus for transmitting at least one data stream comprising a plurality of samples between a first wireless device and a second wireless device using machine-to-machine communication. A method in the first wireless device comprises receiving the at least one data stream; generating a first data packet comprising N of the plurality of samples, wherein N is an integer value of greater than or equal to 2; and transmitting the first data packet to the second wireless device.

Method for bundling sampling data for wireless transmission

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.

It is provided a method for processing input media data. The method is performed in a media data processor and comprising the steps of: obtaining input media data; identifying, in the input media data, sensitive information; generating replacement information, wherein the replacement information is at least partly anonymised information corresponding to the sensitive information, and the replacement information contains at least one characteristic based on the sensitive information; modifying the input media data by replacing its sensitive information with the replacement information, resulting in a modified media data; and providing the modified media data for further processing.

Processing media data with sensitive information

A method implemented in a User Equipment, UE, for a cellular communication system includes transmitting a Random Access (RA) preamble and receiving a Random Access Response (RAR) from a base station (BS) containing a timing advance value, T, indicative of a radio signal propagation delay between the UE and the BS and information indicative of an added time delay, T, between reception of the RA preamble by the BS and transmission of the RAR by the BS.

Enhanced timing advanced filtering

Antenna weights of a plurality of beamformed directions are determined. Transmission on the first beamformed direction is prioritized over transmission on the second beamformed direction, e.g., during beam sweeping. Such techniques may find application in discovery of an access node by a device attached to a wireless network.

Beamforming

A method, wireless device, and network node configured to enable a wireless device to serve as a base station to at least one other wireless device in a communications network, the wireless device being configured to perform predetermined base station functions. The method includes determining a condition triggering a need to provide the predetermined base station functions to the at least one other wireless device, notifying a network node in the communications network that the wireless device is available to provide the predetermined base station functions, receiving approval from the network node to provide the predetermined base station functions, and providing the predetermined base station functions to the at least one other wireless device.

Cellular service improvement and extension by user equipment

A technique for wirelessly charging a wireless device using a charging beam transmitted by a base station in a wireless communication system is disclosed. A method implementation of the technique is performed by the base station and comprises receiving (S), from the wireless device, feedback on charging quality observed by the wireless device, and adjusting (S) the charging beam based on the feedback received from the wireless device.

Technique for wirelessly charging a wireless device in a wireless communication system

Systems and methods are disclosed herein that relate to the use of a Device-to-Device (D2D) sidelink, e.g., in a licensed spectrum, to assist with clear channel assessment in an unlicensed spectrum. In doing so, the hidden node problem and/or the exposed node problem can be mitigated. In some embodiments, a method of operation of a wireless device in a cellular communications network comprises performing a sidelink-assisted clear channel assessment (SLA-CCA) procedure to determine whether to transmit on an unlicensed channel. The SLA-CCA procedure is a Clear Channel Assessment (CCA) procedure that is assisted by information received by the wireless device from one or more other wireless devices over a D2D sidelink in a licensed spectrum. The method further comprises, upon determining to transmit on the unlicensed channel as a result of performing the SLA-CCA procedure, transmitting a transmission on the unlicensed channel.

Sidelink assisted cooperative listen-before-talk

Messages are transmitted to a target device over a wireless network comprising a primary channel in which first messages are transmitted in a random access procedure, and a secondary channel in which second messages are transmitted using a dedicated access procedure, wherein each of the first messages comprises a pointer to the secondary channel, each first message comprising information about the transmitting device and the target device. For each of the first and second message, a transmission opportunity comprising a time slot for transmitting the corresponding message is selected and the primary channel is scanned to determine, based on the received first messages, whether a second message will be transmitted in the time slots selected for the first or second message in which the transmitting device or the target device is involved. The selected transmission opportunities are confirmed or amended based on a result of the scanning.

Message transmission with reduced interference

A first communication node and method therein for activation of a positioning procedure for a target device in a wireless communication network are disclosed. The first communication node determines whether the target device has moved and activates a positioning procedure for the target device when the movement is larger than a threshold.
