A user device, UE, for a wireless communication system communicates with one or more further UEs using a sidelink, SL. The UE is to operate in a Discontinuous Reception, DRX, mode. When being out-of-coverage, the UE is to obtain one or more resources available for a transmission

NR sidelink discontinuous reception resource allocation

An embodiment of a user equipment supports conditional handovers to one or more cells of a cellular network. The user equipment is configured to receive configuration data from the cellular network. The configuration data indicates for a plurality of target cells of the cellular network, conditions to trigger a conditional handover to any of the target cells. The user equipment is further configured to check the conditions with respect to appliance, and, in case of appliance, trigger the conditional handover.

User equipment supporting conditional handovers to cells of a cellular network and a cellular network supporting conditional handovers

A user device, UE, for one or more wireless communication systems, includes one or more transceiver chains. The UE shares at least one transceiver chain with at least two connections to the one or more wireless communication systems. The UE is connected to one or more network entities, like a gNB or another UE, with the connections, and perform one or more operations on the connections at respective operation occasions. When the UE transmits or receives on a current one of the connections, it does not to transmit or receive on the other connections.

Enhanced multi-connection operations

In the field of wireless communication systems or networks, the design of resource pools as they may be used in sidelink communications among users of the wireless communication system, for example in V2X applications, is described. In particular, an improved resource pool design, for example for resource pools to be used in sidelink communications in V2X services in view of the advantages defined by the NR 5G standard, is presented.

NR V2X resource pool design

A user device, UE, for a wireless communication system is described. The wireless communication system has a plurality of user devices, UEs. The UE communicates with one or more further UEs using a sidelink, SL. To operate in a Discontinuous Reception, DRX, mode, the UE receives a DRX configuration from one of a plurality of DRX configuration sources. The plurality of DRX configuration sources are ranked such that each of the DRX configuration sources has a rank different from the remaining DRX configuration sources, and the UE is to select the DRX configuration from the DRX configuration source having the highest rank among the available DRX configuration sources.

NR sidelink discontinuous reception

A user device, UE, for a wireless communication system is described. The wireless communication system includes a plurality of user devices, UEs. The UE communicates with one or more transmitting UEs using a sidelink, supports a certain number of HARQ processes, and buffers one or more transmissions for each HARQ process. During a unicast communication with a transmitting UE using the sidelink, the UE receives from the transmitting UE a transmission during a transmission time interval, the transmission associated to control data, e.g. SCI, including a HARQ process ID, buffers the received transmission for the HARQ process, and combines the buffered transmissions prior to decoding. In case a successfully identified transmission is not buffered, the UE indicates to the transmitting UE that the transmission is not buffered at the UE.

V2X HARQ process management

A user equipment, UE, for a wireless communication network including one or more base stations, performs a transmission to a base station using a grant-free, GF, transmission scheme. The transmission being performed in accordance with a GF transmission configuration. The UE receives from the base station a certain signaling. The certain signaling indicates that the base station failed to identify the UE from the transmission. Responsive to the certain signaling from the base station, the UE retransmits the transmission in accordance with a GF retransmission configuration. The GF retransmission configuration is different from the GF transmission configuration.

ARQ/HARQ-related procedure for grant-free random access

An apparatus includes an antenna and a transceiver. The transceiver transmits a first signal via the antenna, the first signal including a unique identification of the apparatus and a request for receive information about the first signal at a receiver. The transceiver receives from the receiver a second signal via the antenna, the second signal including first information about a direction of arrival (DoA) of the first signal at the receiver and second information indicative of a location of the receiver.

Apparatus, system and method for improving position estimation and/or communication performance in a wireless communication network

Embodiments provide a transceiver, wherein the transceiver is configured to transmit or receive data in at least one transmission time interval on certain allocated resource elements of a wireless communication system, wherein the transceiver is configured to at least partially blank a transmission time interval for a data block to be transmitted or received by the transmitter, wherein the transceiver is configured (a) to signal to another transceiver a transmission grant in a blanked part of the at least partially blanked transmission time interval or (b) to at least partially blank the transmission time interval based on a blanking pattern received from another transceiver.

Sounding feedback utilizing shortened frame structures

A receiver is configured is configured to receive a data signal, the data signal having at least one data signal block, the data signal block having a predefined duration in the time domain, a number of symbols in the time domain and a bandwidth in the frequency domain, wherein the data signal block is received over a plurality of transmission intervals, wherein a length of one transmission interval is shorter than the duration of the data signal block so that a subset of the symbols of the data signal block is received over one transmission interval, and wherein the receiver includes a signal processing device configured to process the symbols of the data signal block which have been received over one transmission interval.

Examples refer to communication networks between user equipments, UEs, with other devices, such as a base station, BS. Examples refer to communication methods, e.g., for uplink, UL. A joint-resource pool (JRP) is defined.

Joint resource pools for uplink communications

A first transceiver for a wireless communication system according to an embodiment is to determine information on an occupancy of a transmission channel. Moreover, the first transceiver is to transmit the information on the occupancy of the transmission channel to a second transceiver. Furthermore, the first transceiver is to determine the information on the occupancy of the transmission channel and to transmit the information on the occupancy of the transmission channel to the second transceiver without having received from the second transceiver a ready-to-transmit message with which the second transceiver would inform the first transceiver that the second transceiver intends to transmit user data to the first transceiver.

A receiver, e.g. an IoT device, receives and processes a radio signal. The radio signal has at least a first frequency band and a second frequency band. The first frequency band includes a first signal, the second frequency band includes a second signal, and each of the first signal and the second signal includes a plurality of frames, each frame having a plurality of subframes (M-subframe). One or more of the subframes of the first signal include connecting information allowing a receiver to establish a connection with a wireless communication system. All of the subframes of the second signal are free of any connecting information. The receiver establishes the connection with the wireless communication system using the connecting information, and, after having established the connection with the wireless communication system and responsive to band information indicating the second frequency band, operate in the second frequency band.
