摘要： A wireless device receives a sidelink (SL) downlink control information (DCI). The SL DCI indicates: one or more first frequency domain resources; one or more first time domain resources; and a periodicity. One or more SL control information (SCI) indicating the periodicity and one or more first SL transmissions is transmitted via a first set of SL resources. The first set of SL resources are determined based on the one or more first frequency domain resources and the one or more first time domain resources. One or more second SL transmissions are transmitted via a second set of SL resources determined based on: the one or more first frequency domain resources; the one or more first time domain resources; and the periodicity.

摘要： In an embodiment a wireless device receives configuration parameters, of a cell, indicating: a first reference signal (RS) of a first transmission reception point (TRP) of the cell; a second RS of a second TRP of the cell; random access channel (RACH) resources of a RACH of the cell; and a power offset value. The wireless device measures a first received power value of the first RS and measures a second received power value of the second RS. The wireless device selects, based on the measuring and the power offset value, an RS from the first RS and the second RS. Then, the wireless device transmits a preamble, associated with the selected RS, via the RACH resources.

摘要： Described are embodiments for uplink transmission using multiple panels. In an embodiment, a wireless device receives configuration parameters indicating a transmission configuration indication (TCI) state index is associated with: a first TCI state, of a first antenna panel, for uplink transmissions; and a second TCI state, of a second antenna panel, for uplink transmissions. The wireless device receives a command indicating the TCI state index and determines, based on the configuration parameters, the first TCI state and the second TCI state associated with the TCI state index indicated in the command. The wireless device transmits, via the first antenna panel, one or more first transport blocks based on the first TCI state. The wireless transmits, via the second antenna panel, one or more second transport blocks based on the second TCI state.

摘要： A wireless device receives message(s) comprising configuration parameter(s) indicating reference signal(s) of a cell. The configuration parameter(s) may indicate one or more preambles for a beam failure recovery procedure. The configuration parameter(s) may indicate a time alignment timer of a timing advance group comprising the cell. The time alignment timer may start in response to receiving a timing advance command for the timing advance group. The beam failure recovery procedure may be initiated in response to detecting a beam failure of the cell. The beam failure of the cell may be detected based on the reference signal(s) of the cell. A preamble of the one or more preambles may be transmitted for the beam failure recovery procedure. The beam failure recovery procedure may be aborted in response to an expiry of the time alignment timer during the beam failure recovery procedure.

摘要： A wireless device receives a DCI from a base station. The DCI comprises a power control command of an uplink shared channel, a CSI request field, a hybrid automatic repeat request process number, and a redundancy version. Validation of the DCI for an activation of a semi-persistent CSI reporting is performed based on: a radio network temporary identifier of the semi-persistent CSI reporting, the hybrid automatic repeat request process number being set to a first value, and the redundancy version being set to a second value. The semi-persistent CSI reporting indicated by the CSI request field is activated in response to the validation being achieved. A semi-persistent CSI report is transmitted, based on the activated semi-persistent CSI reporting, via the uplink shared channel with a transmission power determined based on the power control command.

摘要： A wireless device activates a first downlink bandwidth part (BWP) of a cell and a first uplink BWP of the cell. An active downlink BWP, identified with a second downlink BWP index, is switched from the first downlink BWP to a second downlink BWP. It is determined that the second downlink BWP is configured with one or more beam failure recovery (BFR) parameters. An active uplink BWP, identified with a second uplink BWP index that is the same as the second downlink BWP index, is switched, based on the determining, from the first uplink BWP to a second uplink BWP. The active downlink BWP is switched from the second downlink BWP to a third downlink BWP. Based on a determination that the third downlink BWP is not configured with one or more BFR parameters, the second uplink BWP is kept as the active uplink BWP.

摘要： A wireless device receives message(s) comprising configuration parameter(s) of a first cell and a second cell. The configuration parameter(s) indicate a plurality of bandwidth parts (BWPs) of the first cell. A first uplink BWP of the plurality of BWPs is activated as an active uplink BWP. A beam failure recovery procedure for the second cell is initiated based on detecting a beam failure. A determination that the first uplink BWP is not configured with one or more beam failure recovery resources for the second cell is made. The active uplink BWP of the first cell is switched, based on the determination, from the first uplink BWP to a second uplink BWP, of the plurality of BWPs, configured with the one or more beam failure recovery resources for the second cell. An uplink signal indicating the beam failure is transmitted via the second uplink BWP.
