  • Publication number: 20210274575
    Abstract: A session management function (SMF) receives a request message from a network exposure function (NEF). The request message is for a delivery of a trigger to a wireless device. The request message includes a trigger payload and a trigger indication. The trigger payload includes information for an application on the wireless device. The trigger indication identifies that the request message carries the trigger payload. The SMF sends, via an access and mobility management function (AMF), a non-access stratum (NAS) message to the wireless device. The NAS message includes the trigger indication and the trigger payload. The SMF receives, from the wireless device via the AMF and based on the trigger payload, a request to establish a packet data unit session for the application.

  • Publication number: 20210274539
    Abstract: A wireless device receives a first SR configuration corresponding to first logical channel(s); and a second SR configuration corresponding to second logical channel(s). Based on the first logical channel(s) having data available for uplink transmission: a first counter, of the first SR configuration, is set to a first initial value and incremented based on transmission of a first SR associated with the first logical channel(s); and a random access preamble is transmitted in response to the first counter reaching a first counter value. Based on the second logical channel(s) having data available for uplink transmission: a second counter, of the second SR configuration, is set to a second initial value and incremented based on transmission of a second SR associated with the at least one second logical channel; and a random access preamble is transmitted in response to the second counter reaching a second counter value.

  • Publication number: 20210274542
    Abstract: A wireless device receives one or more messages. The one or more messages may comprise a first RNTI for a first SPS and a second for a second SPS. A downlink control information (DCI) corresponding to one of the first RNTI or the second RNTI may be received. The DCI may be validated, at least based on a cyclic shift value associated with the DCI, if the DCI corresponds to the first RNTI. Otherwise, the DCI may be validated without considering the cyclic shift value. One of the first SPS or the second SPS, corresponding to the DCI, may be activated in response to the validating being successful.

  • Patent number: 11109397
    Abstract: Wireless communications using multiple active resources (e.g., bandwidth parts (BWP)) are described. At least one of multiple active resources (e.g., BWPs) of a first cell may be selected to send scheduling information (e.g., cross-carrier scheduling information) for other cells. A base station may send downlink control information (DCI) for scheduling (e.g., cross-carrier scheduling) a second cell using the selected BWP. A wireless device may monitor a physical downlink control channel (PDCCH) of the selected BWP to detect the DCI for scheduling (e.g., cross-carrier scheduling) the second cell.

    Abstract: A wireless device receives one or more radio resource control messages. The one or more radio resource control messages comprise configuration parameters of semi-persistent channel state information (CSI) reports for transmission via a physical uplink shared channel (PUSCH) of a first cell in a timing advance group. A downlink control information (DCI) indicating activation of semi-persistent CSI is received via PUSCH resources of the PUSCH of the first cell. In response to a time alignment timer of the timing advance group expiring, first PUSCH resources of the PUSCH resources are cleared. The first PUSCH resources occur after the time alignment timer expires.
