    摘要： A terminal apparatus executing radio communication with a base station apparatus, the terminal apparatus: transmits a first message, including a random access preamble and identification information of the terminal apparatus, for starting a random access procedure to the base station apparatus; receives a second message, including a random access response to the first message, from the base station apparatus; and selects one random access preamble group from among a plurality of random access preamble groups on the basis of a first condition, a second condition, a third condition, and a status of the terminal apparatus, in order to notify the base station apparatus of the status of the terminal apparatus when transmitting the first message. Consequently, even when a 2-step random access procedure is adopted, radio resources for the radio communication between the base station apparatus and the terminal apparatus can be used efficiently.

    摘要： A wireless device receives configuration parameters comprising pathloss reference linking indicators for SRS resource sets of a first cell associated with one or more TRPs, wherein each SRS resource set of the SRS resource sets comprises SRS resources, and each SRS resource set is associated with a respective pathloss reference linking indicator of the pathloss reference linking indicators, indicating a cell index identifying a pathloss reference cell. The wireless device transmits, via SRS resources of a first SRS resource set of the SRS resource sets in the first cell, SRSs with a transmission power determined based on a first pathloss RS of a first pathloss reference cell, wherein the first pathloss reference cell is indicated by a first pathloss reference linking indicator, of the pathloss reference linking indicators, associated with the first SRS resource set.

    摘要： A method for selecting a channel for a network element in a shared spectrum communication system is provided. The method comprises identifying a plurality of candidate channels of a frequency band of the shared spectrum communication system. For each of the plurality of candidate channels, the method further comprises determining at least one transmit power estimate based on at least one available interference margin. The at least one available interference margin is based on a power allocation protocol for the shared spectrum communication system. The method further comprises scoring each of the plurality of candidate channels based on the at least one transmit power estimate. The method further comprises ranking the plurality of candidate channels based on the scores for each of the plurality of candidate channels. The method further comprises selecting one of the plurality of candidate channels based on the ranking of the plurality of candidate channels.

    摘要： A method and apparatus for training an artificial intelligence AI model in a wireless network are provided. The method includes: sending first configuration information to a terminal participating in federated learning, where the first configuration information is used to configure at least one of the following: training duration, a time-frequency resource, and a reporting moment; and same training duration, a same time-frequency resource, and a same reporting moment are configured for different terminals participating in federated learning; and receiving a signal obtained through over-the-air superposition of gradients reported by the terminals, where the gradients are gradients that are of an AI model whose training is completed within the training duration and that are reported by the terminals at the reporting moment by using the time-frequency resource.
