  • Radio-network node, wireless device and methods performed therein
    Patent number: 11601969
    Abstract: Embodiments herein relate to method performed by a radio-network node for handling a data transmission, from a wireless device to the radio-network node, in a wireless communication network. The radio-network node schedules one or more resources for carrying an uplink data transmission from the wireless device over a channel, and for carrying a feedback transmission, of a downlink data transmission from the radio-network node, over the same channel. The radio-network node transmits a control message to the wireless device, which control message indicates the one or more resources scheduled for carrying the uplink data transmission and the feedback transmission over the same channel.

    Patent number: 11595157
    Abstract: Embodiments include methods for a wireless device operating in a wireless communication network. Such methods include receiving from the wireless communication network, during a first transmission-time interval (TTI), an explicit request for automatic repeat-request (ARQ) feedback from the wireless device. The request can include an indication of one of the following: a range of ARQ process numbers for which the ARQ feedback is requested, or a range of TTIs, indicating that the wireless device is to provide ARQ feedback for all ARQ processes active during the indicated range of TTIs. Such methods also include transmitting to the wireless communication network, during a second TTI after the first TTI, ARQ feedback information for the ARQ processes indicated in the request. Other embodiments include complementary methods performed by a network node, as well as wireless devices and network nodes configured to perform such methods.

  • RANDOM-ACCESS RESPONSE WITH ANALOG BEAMFORMING
    Publication number: 20230028292
    Abstract: A system and method of Random-Access Response, RAR, messaging when a base station employs narrow beamforming. Multiple RAR messages are successively transmitted from the base station to a User Equipment, UE, before any response to a RAR message is received from the UE. Thus, despite any calibration mismatch between Uplink, UL, and Downlink, DL, beams in the beamformed system, a RAR message is not only received by the UE, but is received over the most-suitable DL beam for that UE. Each RAR message may contain a message-specific scheduling-delay indicator in the UL grant carried in the RAR message to provide an adjustable time delay for the UE's uplink transmission scheduled by the UL grant. Multiple RAR transmissions can schedule a single UL transmission at a specific time instance or different UL transmissions at different time intervals. The UE may report to the base station the best DL RAR transmission detected by the UE.
