摘要： A base station may communicate with a wireless device. A message may be used to indicate information for a layer 1 and/or layer 2 triggered mobility (LTM) procedure. For example, a medium access control (MAC) control element (CE) may indicate various information such as a target cell for the LTM procedure, whether to perform a random access (RA) procedure toward a target cell, a TA value, a bandwidth part (BWP) of BWPs of the target cell, and/or other information associated with the LTM procedure.

摘要： A base station may communicate with other base stations. The base station may hand over one or more wireless devices served by its cell to a neighboring base station, for example, to save overall energy consumption in the network. Feedback information (e.g., one or more messages) may be provided by the neighboring base station to the base station to help further decision-making related to handing over other wireless device(s).

摘要： A wireless device may communicate with a base station via a primary cell (PCell) and one or more secondary cells. A plurality of types of handovers, such as a layer 1 / layer 2 triggered handover or a conditional handover, may be indicated to the wireless device for switching its PCell. One or more conditions, such as a priority associated with a handover type, may be used to determine which type of handover to perform.

摘要： A group of wireless devices may use shared resources to communicate information to a base station. At least one configuration parameter (e.g., QoS parameter(s)) associated with over-the-air computation may be used for group uplink transmissions. Data associated with the group of wireless devices may be determined, based on an aggregation of the group uplink transmissions, and/or may be provided to a network node using the configuration parameter(s).

摘要： Systems, apparatuses, and methods are described for wireless communications. Wireless communications between a base station and one or more wireless devices are described. A wireless device may use power ramping for transmissions and/or retransmissions. Power ramping may be used during a random access procedure. A wireless device may fail a listen before talk procedure before sending a preamble or a transport block on an unlicensed band. The wireless device may use power ramping to determine a power of transmission of the preamble and/or transport block based on the prior preamble or a transport block transmission. Power ramping may be determined using a power ramping counter value and/or a power ramping step value, which may be shared or associated with the preamble and/or a transport block.

摘要： A wireless device may communicate with a base station via a cell. A cell may be selected for wireless communications based on having a configuration that is capable of serving certain wireless resources associated with a wireless device. A wireless device may select a cell that comprises a communication link supporting certain wireless resources that may be required for use by the wireless device.

摘要： Systems, apparatuses, and methods are described for wireless communications. A policy control function may determine a policy and charging control rule comprising one or more Ethernet source MAC addresses and a quality of service policy. The policy control function may send the policy and charging control rule to a session management function to provide an Ethernet PDU session for a wireless device.

摘要： Wireless communications for transmission power control are described. A reference signal may be mapped to a power control parameter set. A message to schedule a transmission may be received that indicates the power control parameter set. A transmission power for the scheduled transmission may be determined based on the reference signal.

摘要： Wireless resource determination and use are described. A wireless device may determine to use a resource (e.g., PUCCH resource), indicated by control information (e.g., DCI), for sending an acknowledgement (e.g., HARQ-ACK feedback) of a reception of data (e.g., at least one transport block). The control information may be received in a message of a plurality of messages. The wireless device may select the control information (e.g., for determining the resource) from among other control information in the plurality of messages, based on one or more factors.

摘要： A base station may communicate with other base stations for handover decisions. Information about energy consumption of other base stations may be used by the base station for efficient handover decisions. Predictions of energy consumption may be exchanged before making a handover decision so that handover decisions may be based on energy usage.
