摘要： A wireless device receives a radio resource control message from a base station. The radio resource control message comprises one or more configuration parameters for a random access channel. A downlink control information is received that comprises a field indicating a slot format indication, for a slot, among a plurality of SFIs. The plurality of SFIs indicate uplink, flexible, and random access symbols. The wireless device determines radio resources of one or more random access channel occasions of the slot based on the one or more configuration parameters and at least one random access symbol indicated by the slot format indication for the slot. A preamble is transmitted via the radio resources of the one or more random access channel occasions.

摘要： A wireless device receives one or more messages. The one or more messages comprise configuration parameters of a cell. The configuration parameters indicate: a plurality of slot format combinations of the cell; a plurality of reference signals (RS) of the cell; and a channel occupancy time (COT) radio network temporary identifier (RNTI). The wireless device receives a downlink control information (DCI) scrambled by the COT-RNTI indicating a slot format combination of the plurality of slot format combinations, for an RS of the plurality of RSs. A channel occupancy time (COT) structure is determined for the RS based on the slot format combination. A transport block is transmitted, via uplink resources of the cell, based on the COT structure.

摘要： A wireless device receives one or more configuration parameters for uplink bandwidth parts (BWPs) of a cell. A first preamble, for a random-access procedure, is transmitted via a first uplink BWP of the uplink BWPs. A random-access response comprising a backoff indicator is received. A backoff window associated with the backoff indicator is started. A second uplink BWP of the uplink BWPs, that is different from the first uplink BWP, is selected for transmission of a second preamble during the backoff window. The wireless device transmits, via the second uplink BWP and based on the selecting, the second preamble for the random-access procedure.

摘要： A wireless device transmits, one or more radio resource control (RRC) messages indicating assistance information for a sidelink operation. The assistance information indicates: an identifier indicating a logical channel associated with a sidelink traffic; and one or more periodicities associated with the logical channel. In response to the assistance information, one or more second RRC messages indicating one or more configured grant configurations determined based on the one or more of periodicities of the logical channel is received. The wireless device triggers, a transmission of a buffer status report in response to sidelink data of the logical channel becoming available. A scheduling request (SR) is transmitted. In response to the SR: the transmission of the buffer status report is cancelled; and one or more activation commands indicating activation of the one or more configured grant configurations is received.

摘要： A wireless device receives configuration parameters of a bandwidth part comprising resource block (RB) sets, each RB set having an RB index. The wireless device receives, during a downlink control channel monitoring occasion, a plurality of downlink control information (DCI)s and each DCI of the plurality of DCIs is received via a respective RB set of the RB sets. The wireless device transmits a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook comprising HARQ-ACK information bits corresponding to the plurality of DCIs, wherein the HARQ-ACK information bits are in order of indexes of RB sets corresponding to the DCIs.

摘要： A wireless device receives one or more messages from a base station. The one or more messages comprise: first configuration parameters of one or more cells grouped into a timing advance group; second configuration parameters of a time alignment timer for the timing advance group; and third configuration parameters of semi-persistent channel state information (CSI) reports for transmission via a first cell of the one or more cells. A downlink control information is received. The downlink control information indicates activation of a plurality of resources of the first cell for the semi-persistent CSI reports. A semi-persistent CSI report, of the semi-persistent CSI reports, is transmitted via a first resource of the plurality of resources. In response to the time alignment timer expiring, second resources of the plurality of resources that occur after the time alignment timer expires are cleared.

摘要： A wireless device receives configuration parameters indicating one or more first RSs, on a first cell, as candidate RSs for a BFR procedure of a second cell. The wireless device triggers, in response to a number of beam failure instances on the second cell, the BFR procedure for the second cell. The first cell is deactivated. Based on the deactivating the first cell, the BFR procedure for the second cell is cancelled.

摘要： A wireless device initializes a candidate resource set. The candidate resource set comprises candidate resources in a selection window. The wireless device receives a second sidelink transmission. The second sidelink transmission comprises sidelink control information (SCI). The SCI indicates first resources during the selection window. The SCI indicates a priority of the second sidelink transmission. The priority is used for excluding the first resources from the candidate resource set. The wireless device excludes the first resources from the candidate resource set based on the priority being higher than a first priority threshold. The wireless device selects second resources from the candidate resource set based on the excluding of the first resources from the candidate resource set. The wireless device transmits a first sidelink transmission via the second resources.

摘要： A wireless device receives one or more radio resource control (RRC) messages indicating: uplink resources of a first cell; and a sidelink resource pool of the first cell. A power headroom value of the first cell is selected among: a first power headroom value of an uplink transmission via the uplink resources; and a second power headroom value of a sidelink transmission via the sidelink resource pool. A power headroom report is transmitted. The power headroom report comprises: the power headroom value of the first cell; and a power headroom type indicating whether the power headroom value of the first cell is for the uplink transmission or the sidelink transmission.

摘要： A first wireless device receives, from a base station, configuration parameters of a resource pool of a sidelink. The configuration parameters indicate a primary zone configuration, a secondary zone configuration, and a first primary zone identifier of a first primary zone. a second primary zone identifier of a second primary zone in which the first wireless device is positioned, is determined based on a geographic location of the first wireless device using the primary zone configuration. A secondary zone identifier of a secondary zone in which the first wireless device is positioned, is determined based on the geographic location using the secondary zone configuration. The first wireless device transmits control information indicating the secondary zone identifier to second wireless device(s). The control information is transmitted via the resource pool, in response to the second primary zone identifier being the same as the first primary zone identifier.
