  • Random Access in a Wireless Communication Network
    Publication number: 20230156818
    Abstract: A wireless device (40) determines that no resources configured for random access on a link support a minimum gap requirement of the wireless device (40), where the minimum gap requirement is a minimum gap required in time between an end of a transmission of a random access preamble (16) and a start of a transmission of a payload (18). Based on this determination, the wireless device either (i) transmits a random access preamble (16) using the resources configured for random access on the link, but waits to transmit a payload (18) until the wireless device (40) receives a random access response in response to the random access preamble (16); (ii) delays random access on the link until resources configured for random access on the link support the minimum gap requirement of the wireless device (40); or (iii) selects to perform random access on a different link.

  • RADIO NETWORK NODE, USER EQUIPMENT, AND HANDOVER METHODS PERFORMED IN A COMMUNICATION NETWORK
    Publication number: 20230110446
    Abstract: Embodiments herein relate e.g. to a method performed by a first radio network node for handling communication in a wireless communication network. The first radio network node transmits, to a UE served by the first radio network node in a first cell, a message for the UE. The message includes an indication for a reconfiguration for communicating with the first radio network node in the first cell during a handover of the UE to a second cell, wherein the message is associated with a configuration for handing over the UE to the second cell based on whether an execution condition is fulfilled or not, and/or for maintaining a connection to the cell while a connection to the second cell is being established. The first radio network node then receives information, from the UE, indicating that the UE has applied the reconfiguration.

  • METHOD AND APPARATUS FOR CONFIGURING BEAMFORMING OPERATIONS IN A WIRELESS COMMUNICATION NETWORK
    Publication number: 20230098741
    Abstract: A wireless communication device transmits beam sweeping information that indicates a beam sweeping property of the device, and a network node in an associated wireless communication network configures transmission or reception beamforming with respect to the device at one or more Transmission/Reception (TRPs) in the network, based on the beamforming property. Among the various advantages flowing from configuring network-side beamforming for the device in view of the beamforming property, the network need not configure its beamforming operations according to worst-case or minimum-capability assumptions for the device, and, instead tailors its transmission or reception beamforming in dependence on the beamforming property of the device.

  • Switching Random Access Triggered by Backoff
    Publication number: 20230083993
    Abstract: A method by a wireless device includes transmitting, to a network node, a first message to initiate a 2-step Random Access (RA) procedure to access a network. After transmitting the first message, the wireless device receives, from the network node, a second message including at least one parameter indicating that the wireless device is to wait a period of time before reattempting to access the network using the 2-step RA procedure. Based on the parameter indicating that the wireless device is to wait a period of time before reattempting to access the network using the 2-step RA procedure, the wireless device attempts to access the network using a 4-step RA procedure without waiting for the period of time.

  • Methods and apparatuses for performing new radio cell selection/re-selection
    Patent number: 11601859
    Abstract: A user equipment (UE) operates to select and/or re-select among radio cells provided by access nodes of a wireless communication system. The UE measures quality of beams detected from each of the cells. For each of the cells, the UE derives cell quality based on the quality of the beams from the cell. For each of the cells, the UE determines the number of good beams among the beams from the cell based on a cell quality threshold received via system information. The UE ranks the cells in a ranking list relative to each other based on the number of good beams associated with respective ones of the cells and the cell quality. The UE controls, based on the ranking of the cells in the ranking list the number of good beams and the cell quality, selection and/or re-selection of a cell among the cells that is to be used for UE radio communications.
