摘要： A wireless device receives configuration parameters comprising first parameters of downlink RSs and second parameter indicating that a default beam is used for uplink transmission. A DCI indicating a first uplink transmission via a PUSCH resource is received. A spatial relation information, for the first uplink transmission, is determined to be associated with one of the downlink reference signals in response to the second parameter indicating that the default beam is used. A transport block is transmitted via the PUSCH resource according to the spatial relation information.

摘要： A wireless device receives one or more RRC messages comprising configuration parameters of a cell. The configuration parameters indicate uplink BWPs of an uplink carrier of the cell. The uplink BWPs comprise a first uplink BWP and a second uplink BWP. The configuration parameters further indicate a sidelink BWP of the uplink carrier of the cell. A numerology of the second uplink BWP is different than a numerology of the sidelink BWP. The wireless device activates the first uplink BWP. The wireless device activates the sidelink BWP. The wireless device switches from the first uplink BWP to the second uplink BWP as an active uplink BWP. The wireless device deactivates, based on the switch, the sidelink BWP.

摘要： A wireless device receives radio resource control message(s) from a base station indicating random access resources of an uplink bandwidth part of a cell, that comprise two-step random access resources and four-step random access resources. Determining that the two-step random access resources comprise contention-free two-step random access resources, the wireless device selects from among a two-step random access type and a four-step random access type, the two-step random access type. Based on the two-step random access type, a preamble is transmitted to the base station using the two-step random access resources.

摘要： A wireless device receives configuration parameters indicating: a plurality of hybrid automatic repeat request (HARQ) processes of a cell; a subset of the plurality of HARQ processes; and a HARQ process identifier offset. A downlink control information (DCI) comprising a first HARQ process identifier and a resource assignment is received. The first HARQ process identifier indicates a HARQ process in the subset of the plurality of HARQ processes. A second HARQ process identifier is determined based on the first HARQ process identifier and the HARQ process identifier offset. The second HARQ process identifier indicates a second HARQ process of the plurality of HARQ processes. Based on the resource assignment, a transport block of a HARQ buffer associated with the second HARQ process is transmitted.

摘要： A wireless device receives one or more radio resource control messages. The one or more radio resource control messages indicating: a first control resource set (coreset) group; a second coreset group; a first physical uplink control channel (PUCCH) cell associated with a first index indicating the first coreset group; and a second PUCCH cell associated with a second index indicating the second coreset group. one or more transport blocks are received. A determination is made of a PUCCH cell for transmitting hybrid automatic repeat request (HARQ) feedback of the one or more transport blocks. The determining comprises: determining the first PUCCH cell in response to the one or more transport blocks being scheduled via the first coreset group; and determining the second PUCCH cell in response to the one or more transport blocks being scheduled via the second coreset group. The HARQ feedback is transmitted via the determined PUCCH cell.

摘要： A wireless device receives, before a scheduled sidelink transmission via a resource of one or more resources of a sidelink resource pool of a cell, a downlink control information (DCI). The DCI indicates switching from a first bandwidth part of the cell to a second bandwidth part of the cell as an active bandwidth part. In response to the DCI: the second bandwidth part is activated after a delay from the reception of the DCI; the scheduled sidelink transmission via the resource of the one or more resources is dropped; and monitoring physical sidelink control channels for sidelink control information is skipped during the delay.

摘要： A wireless device receives one or more messages. The one or more messages indicate: a plurality of repetition values of a physical sidelink shared channel (PSSCH); and a repetition threshold for the PSSCH. A sidelink control information is received. The sidelink control information schedules a transport block. The sidelink control information indicates a first repetition value of the plurality of repetition values. The transport block is received via the PSSCH. A determination is made, based on the first repetition value and the repetition threshold, to transmit an acknowledgment for the transport block. The acknowledgment for the transport block is transmitted.

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.

摘要： A wireless device receives configuration parameters of one or more configured grants of an unlicensed cell. The wireless device receives a downlink control information indicating an uplink grant for a first TB corresponding to a first HARQ process. The wireless device stores, based on a first LBT procedure indicating a busy channel, the first TB in a first HARQ buffer associated with the first HARQ process. The first LBT is for a scheduled transmission of the first TB. The wireless device flushes, based on a second LBT procedure indicating a busy channel, a second HARQ buffer associated with a second HARQ process. The second LBT procedure is for a scheduled transmission of a second TB via a first configured grant of the one or more configured grants.

摘要： A wireless device initiates a beam failure recovery procedure in response to detecting a first number of beam failure instances. A beam failure recovery timer is started with a first timer value. A first reference signal is selected in response to an expiry of the beam failure recovery timer. A first preamble associated with the first reference signal is transmitted. A downlink control channel for a downlink control information is monitored during a response window and in response to transmitting the first preamble. A preamble transmission counter is incremented, from a value of the preamble transmission counter before the expiry of the beam failure recovery timer, in response to not receiving the downlink control information during the response window. A second preamble for the beam failure recovery procedure is transmitted in response to the preamble transmission counter indicating a second number equal to or less than a third number for preamble transmissions.
