  • Patent number: 12143321
    Abstract: A base station for a wireless communication network is provided. The wireless communication network includes a plurality of base stations, each base station to serve one or more users. One or more users are served by a plurality of base stations to receive a first data signal from the base station and a second data signal from at least one further base station using multi-user superposition transmission, MUST. The base station includes a backhaul interface for a communication with one or more of the plurality of base stations of the wireless communication network. For transmitting the first data signal to one or more users served by the base station and by the further base station, the base station is configured to negotiate a MUST setting with the further base station via the backhaul interface, and map data of the first data signal using a first transmit constellation set according to the negotiated MUST setting.

  • Patent number: 12101806
    Abstract: An apparatus, for wideband communication with one or more transceivers in a wireless communication system using one or more subbands of a predefined wideband, is configured to perform initial Listen-Before-Talk, LBT, for each subband of the predefined wideband so as to determine from the predefined wideband one or more non-occupied subbands on which the wideband communication is allowed during a certain transmission time, and during the certain transmission time, transmit to and/or receive from the transceiver using the non-occupied subbands. During the certain transmission time and in case the initial LBT indicted that one or more of the subbands are occupied, the apparatus is configured to perform a further LBT for the one or more occupied subbands so as to determine one or more of the initially occupied subbands being no longer occupied, and transmit to and/or receive from the transceiver using, in addition to the initially non-occupied subbands, the one or more no longer occupied subbands.

  • Publication number: 20240243852
    Abstract: 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.

  • Publication number: 20240215112
    Abstract: A wireless communication system includes one or more base stations, and a plurality of UEs for a sidelink communication using sidelink resources. The UEs includes a transmitting UE and a receiving UE using a subset of the sidelink resources of the wireless communication system. The receiving UE sends over the sidelink a sidelink feedback to the transmitting UE. The sidelink feedback indicates for a data transmission a successful or non-successful reception at the receiving UE. The transmitting UE reports the sidelink feedback to a base station. The base station provides to the transmitting UE, responsive to the sidelink feedback, sidelink resources for a possible retransmission of a data packet over the sidelink to the receiving UE. The reporting of the sidelink feedback to the base station by the transmitting UE is activated or deactivated responsive to one or more conditions.
