摘要:
Methods performed by a wireless device, such as a user equipment, operating in a dormant mode comprise performing a measurement on each of a plurality of resources from a predetermined set of resources or demodulating and decoding information from each of a plurality of resources from a predetermined set of resources, such as a set of beams. The methods further include evaluating the measurement or the demodulated and decoded information for each of the plurality of resources against a predetermined criterion, and then discontinuing the performing and evaluating of measurements, or discontinuing the demodulating and decoding and evaluation of information, in response to determining that the predetermined criterion is met, such that one or more resources in the predetermined set of resources are neither measured nor demodulated and decoded. The methods further comprise deactivating receiver circuitry, further in response to determining that the predetermined criterion is met. The method further comprises receiving, in a first downlink subframe, a first Orthogonal Frequency-Division Multiplexing transmission formatted according to a first numerology and receiving, in a second downlink subframe, a second OFDM transmission formatted according to a second numerology, the second numerology differing from the first numerology.

Methods, devices, and computer programs for improving the efficiency of multiuser multimedia messaging services are disclosed. A multimedia message is sent from an originator user device to an originator server and further to one or more recipient servers to which recipient user devices as addressed are associated to. The one or more recipient servers execute a multicast delivery for distributing the multimedia message to the recipient user devices and/or an improved reporting of a transmission state of the multimedia message by receiving status messages from the recipient user devices, each status message comprising an indication of an individual transmission state of the multimedia message at one of the recipient user devices, aggregating the indications into a report representing the transmission state of the multimedia message, and sending the report to the originator server.

Methods of operating a first VAE server for identifying a second VAE server are disclosed. V2X message information per geographical area is received from a V2X application specific server. Position information is received from a VAE client of a wireless device, wherein the position information indicates a position of the wireless device. Responsive to receiving the position information and responsive to the V2X message information per geographical area, a second VAE server is identified based on the position information. The second VAE server is identified by transmitting a service continuity request, including the position information, to a plurality of VAE servers including the second VAE server. A service continuity response message, including an identifier of the second VAE server, is received from the second VAE server.

The invention relates to a method, a broadcast management centre, a router, a host and a system for performing broadcast in a point-to-point oriented packet-switched telecommunication network. The basic idea is to use multicast for parts of the transmission within said telecommunication network. The multicast technique is used to send broadcast data to a geographical broadcast group to which a network node belongs. The network nodes are configured to a certain geographical broadcast group by the broadcast management centre.

Die vorliegende Erfindung betrifft ein Verfahren zur Zuordnung einer Adresse eines datendienstanbietenden Servers zu einer Kommunikationsvorrichtung wie beispielsweise einem Mobilfunkgerät oder einer SIM-Karte. Bei der Zuordnung wird die Serveradresse aus einer Menge von Adressenbezeichnern ausgewählt. Jeder Adressenbezeichner bezeichnet unabhängig von der aktuellen Serverkonfiguration des Kommunikationsnetzes einen gültigen Server. Die Serveradresse kann aus einem festen und einem variablen Anteil zusammengesetzt werden. Weiterhin können die Adressenbezeichner, beispielsweise mittels eines sogenannten DNS Servers aktualisiert werden. Das beschriebene Serveradressenzuordnungsverfahren verbessert die Skalierbarkeit des Kommunikationssystems und bietet eine effiziente Maßnahme zur Lastverteilung sowohl für datendienstanbietende Anwendungsserver als auch für sogenannte DNS Server. Weiterhin betrifft die Erfindung eine entsprechende Kommunikationsvorrichtung zur Zuordnung einer Serveradresse, sowie ein entsprechendes Kommunikationssystem und Computerprogramm.

A mobile device (10) subscribes to receive messages targeted to a first geographical area (18-A), e.g., a first tile or area of a grid for geocasting. The mobile device (10) also subscribes to receive messages targeted to a second geographical area (18-B), e.g., a second tile or area of the grid for geocasting. The mobile device (10) notably does this such that the mobile device (10) is simultaneously subscribed to receive messages targeted to the first geographical area (18-A) and to receive messages targeted to the second geographical area (18-B).
摘要:
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 downlink subframe, a first Orthogonal Frequency-Division Multiplexing, OFDM, transmission formatted according to a first numerology and receiving, in a second downlink subframe, a second OFDM transmission formatted according to a second numerology, the second numerology differing from the first numerology, where the first numerology has a first subcarrier spacing and the second numerology has a second subcarrier spacing, the first subcarrier spacing differing from the second subcarrier spacing. The example method further includes, in the same wireless device, receiving and processing first Layer 2 data on a first physical data channel and receiving and processing second Layer 2 data on a second physical data channel, wherein the receiving and processing of the first Layer 2 data comprises the use of soft HARQ combining and wherein the receiving and processing of the second Layer 2 data comprises no soft HARQ combining. Variants of this method, corresponding apparatuses, and corresponding network-side methods and apparatuses are also disclosed.

A fifth-generation wireless communications network includes a server node, radio network equipment and a wireless device. In an example method, a server node receives first user data in response to (i) the wireless device receiving from the radio network equipment information indicating a plurality of uplink access configurations, each uplink access configuration including a random access configuration; (ii) the wireless device receiving an uplink access configuration index; (iii) the wireless device using the uplink access configuration index to identify an uplink access configuration from among the indicated plurality of uplink access configurations, and (iv) the wireless device transmitting the first user data to the wireless communications network according to the identified uplink access configuration. In the example method, further, the server node initiates transmission of second and third user data. This causes the wireless device to (v) receive from the radio network equipment, in a first downlink subframe, a first OFDM transmission formatted according to a first numerology and carrying the second user data, and (vi) receive from the radio network equipment, in a second downlink subframe, a second OFDM transmission formatted according to a second numerology and carrying the third user data, wherein the numerologies have different subcarrier spacings.
