Abstract:
An access and mobility management function (AMF) receives, from a base station, a non-access stratum (NAS) request message of a wireless device (100) indicating one or more network slices. The AMF determines to perform network slice specific authentication and authorization, NSSAA, for a first network slice of the one or more network slices. The AMF sends, to the base station, based on the determining, an indication that the first network slice is pending.
Abstract:
A first wireless device transmits a discovery message to a second wireless device (3010). The discovery message comprises a parameter. The parameter indicates that the first wireless device is only allowed to access a cell associated with at least one closed access group (3020).
Abstract:
A wireless device receives configuration parameters. The configuration parameters are for a first antenna group for a cell. The configuration parameters are for a second antenna group for the cell. The wireless device triggers a power headroom report in response to activating the first antenna group. The wireless device transmits the first power headroom report.
Abstract:
A first access node receives, from a second access node, configuration parameters indicating whether radio resources are allowed to be activated for a first area of a first child access node and a second area of a second child access node in an overlapping time duration. The first access node transmits, to at least one of the first child access node and the second child access node and based on the configuration parameters, an activation indication of the radio resources for the first area or the second area.
Abstract:
A wireless device receives one or more messages comprising configuration parameters for a cell group. The cell group comprises: a first cell configured with one or more beam failure recovery (BFR) parameters; and one or more second cells configured to use the first cell for a BFR procedure. A deactivation timer of the first cell is restarted in response to receiving a physical downlink control channel indicating an uplink grant or a downlink assignment for any secondary cell, other than the first cell, in the cell group.
Abstract:
A wireless device increments a beam failure instance counter based on: one or more received powers of one or more downlink signals being less than one or more threshold values. A determination is made that the one or more downlink signals are transmitted due to one or more downlink listen before talk procedures indicating clear channel. A random access preamble is transmitted based on the beam failure instance counter reaching a first value.
Abstract:
A wireless device receives one or more messages comprising one or more configuration parameters of a cell. A beam failure recovery procedure of the cell is initiated based on a beam failure detection for the cell. The cell is transitioned into a dormant state during the beam failure recovery procedure. A channel state information for the cell is reported in the dormant state. The beam failure recovery procedure is aborted based on the transitioning the cell into the dormant state during the beam failure recovery procedure.
Abstract:
A wireless device receives parameters indicating that first bearer(s) of bearer(s) are configured with duplication. Each bearer in bearer(s) is identified by an identifier. A control element of a fixed size of one octet is received. The control element comprises a sequence of activation bits comprising a first activation bit for a first bearer in the first bearer(s). A first position of the first activation bit in the one octet identifies a second position of a first bearer identifier in an ordered list of the bearer identifiers. A first value of the first activation bit indicates whether the PDCP duplication for the first bearer is activated or deactivated. In response to the control element indicating that the PDCP duplication is activated for the first bearer, a first packet corresponding to the first bearer is transmitted via a first cell and a duplicate of the first packet via a second cell.
Abstract:
Introduction of a timing advance group concept into LTE TS 36.321 for release 11. A timing advance group (TA group) comprises up to five cells. For each TA group the UE only needs a single TA timer. The initial timing alignment is achieved by a base station initiated RACH pro¬ cedure. The configuration of multiple TA groups depends on the UE capabilities report which defines Multi-TA capability of the UE based on each supported band combination A base station receives radio capability parameters from a wireless device on a first signaling bearer on a primary cell. The radio capability parameters comprise a first sequence of radio configuration parameters. A first radio configuration parameter in the first sequence comprises a first parameter indicating whether multiple timing advance groups are supported for a first band combination. The first band combination is in a second sequence of band combinations. The index of the first radio configuration parameter in the first sequence determines the index of the first band combination in the second sequence.
Abstract:
Introduction of a timing advance group concept into LTE TS 36.321 for release 11. A timing advance group (TA group) comprises up to five cells. For each TA group the UE only needs a single TA timer. The initial timing alignment is achieved by a base station initiated RACH procedure. The BTS sends its initiation command on PDCCH. The TA command is a MAC element that comprises a 2 bit TA group index. A base station transmits timing advance commands to wireless devices for adjusting uplink transmission timing by the wireless devices. Each of the wireless devices operate in a mode. A wireless device interprets a timing advance command depending on the mode in which the wireless device is operating. Each of the timing advance commands consists of a subheader having the same value for the each of the timing advance commands, a control element comprising a timing advance value, and an information element interpreted differently, depending on the wireless device operating mode.
