  • Publication number: 20240056912
    Abstract: An example method according to some of the techniques described below is performed by a device operating in a wireless network, where the device could be a UE or a network node, e.g., an NR gNB. This example method includes the step of determining (610) whether a receive-to-transmit or transmit-to-receive switching limitation of a UE can be met during a dual-active protocol stack handover for the UE from a source cell to a target cell. The method further includes the step of taking one or more mitigation actions (620) in response to said determining. Mitigation actions might include, for example, stopping a downlink reception early or starting a scheduled transmission late, in various embodiments or instances.

  • Patent number: 11777696
    Abstract: A wireless device is configured to receive an activation command that commands the wireless device to activate a serving cell. The wireless device is configured to activate the serving cell within a maximum delay since receiving the activation command. The maximum delay depends on whether there is at least one other serving cell already activated for the wireless device in the same frequency band as that in which the serving cell is to be activated.

  • Patent number: 11622329
    Abstract: A network node in a wireless communication network generates configuration information that configures an extent to which a wireless communication device autonomously adapts a number of different receiver components that the wireless communication device uses under different conditions at the wireless communication device. In some examples, the different conditions may be associated with correlation of propagation channels received at the wireless communication device. The network node transmits the configuration information to the device. Correspondingly, the device autonomously adapts the number of different receiver components that the wireless communication device uses in accordance with the configuration information.
