The base station central unit may include one or more processors and memory storing instructions that, when executed by the one or more processors, cause the base station central unit to send, to the base station distributed unit, an indication that a cell is associated with a first non-public network (NPN); and to send, to the base station distributed unit, a request for configuration of the cell for a wireless device that supports the first NPN. The base station distributed unit may include one or more processors and memory storing instructions that, when executed by the one or more processors, cause the base station distributed unit to receive the indication and the request for configuration of the cell.

Abstract: A first base station determines that session resources for a network slice are not available for a wireless device. The first base station sends to a second base station and based on the determination, a request for a handover of the wireless device. The request comprises: an identifier of the network slice for the handover; and a cause information element indicating that a cause for the handover is that the session resources are not available for the network slice at the first base station. A response to the request is received from the second base station.

Abstract: An access and mobility management function (AMF) receives from a first wireless device a non-access stratum (NAS) message comprising an identifier (ID) of a group communication session. The AMF receives from a session management function (SMF) a message comprising a list of one or more second wireless devices associated with the group communication session and a list of one or more packet data unit (PDU) sessions. The AMF determines, based on a state of the one or more second wireless devices, to page the one or more second wireless devices. The AMF receives from the one or more second wireless devices one or more service request messages.

Abstract: A base station transmits, to a wireless device, message(s) comprising a first maximum value for a preamble transmission counter and a second maximum value for a second counter. The base station transmits a control order initiating a random access procedure on a first unlicensed cell. The first maximum value may indicate a maximum number of preamble transmissions for the random access procedure. The second maximum value may indicate a number of listen-before-talk (LBT) failures of at least one LBT procedure performed for transmission of a preamble for the random access procedure. A value of the preamble transmission counter may be kept the same. A value of the second counter may be incremented based on the at least one LBT failure. The random access procedure may be cancelled based on either the preamble transmission counter reaching the first maximum value or the second counter reaching the second maximum value.

The base station starts reception of channel state information for the PUCCH secondary cell from a third time interval that is a number of time intervals after the first time interval.

Abstract: A base station transmits, to a wireless device, configuration parameters of a secondary physical uplink control channel (PUCCH) group. The configuration parameters include a PUCCH secondary cell and a secondary cell. The base station transmits, during a first time interval, a command activating the secondary cell.

In response to activation of the PUCCH secondary cell being completed in or after the pre-determined number of time intervals after the first time interval, the positive number is based on when the activation of the PUCCH secondary cell is completed by the wireless device.
