摘要： A wireless device receives configuration parameters of one or more configured grants of an unlicensed cell. The wireless device transmits, based on a configured grant of the one or more configured grants, one or more code block groups of a transport block and a code block group transmission information. The code block group transmission information indicates a presence of the one or more code block groups for the transport block. The wireless device receives a downlink control information comprising a first field and a second field. The first field indicates that the base station received the code block group transmission information. The second field indicates hybrid automatic repeat request feedbacks for the one or more code block groups.

摘要： A wireless device receives one or more downlink control information. The one or more downlink control information indicate negative acknowledgements. The negative acknowledgements are for one or more first code block groups of a first transport block corresponding to a first hybrid automatic repeat request (HARQ) process and one or more second code block groups of a second transport block corresponding to a second HARQ process. The wireless device determines that a size of a first configured grant is sufficient to retransmit the one or more first code block groups and the one or more second code block groups. Based on the determining, the wireless device retransmits, via radio resources of the first configured grant, the one or more first code block groups and the one or more second code block groups.

摘要： A wireless device receives one or more messages comprising: first configuration parameters of a plurality of cells comprising a primary cell and a secondary cell; and bandwidth part configuration parameters comprising a value for a bandwidth part inactivity timer. A downlink control information is received on an active bandwidth part of the primary cell. The downlink control information indicates a resource assignment. In response to the receiving the downlink control information, a determination is made that no random access procedure is ongoing on the secondary cell. The bandwidth part inactivity timer of the active bandwidth part of the primary cell is started in response to the determining. In response to an expiry of the bandwidth part inactivity timer, a switch is made from the active bandwidth part to a default bandwidth part.

摘要： A wireless device may receive at least one message comprising: first configuration parameters of a first bandwidth part, and second configuration parameters of a second bandwidth part. The second configuration parameters may comprise a scheduling request configuration indicating scheduling request resources for a logical channel. A scheduling request may be triggered in response to data becoming available for the logical channel. A random access process may be started in response to a valid scheduling request resource for the logical channel not being available on the first bandwidth part. A downlink control information may be received. The downlink control information may indicate switching from the first bandwidth part to the second bandwidth part. In response to the scheduling request resources being available on the second bandwidth part: the random access process may be cancelled, and a scheduling request signal may be transmitted via the scheduling request resources.

摘要： A wireless device transmits, for a random access procedure, a first preamble via a cell comprising a first sub-band and a second sub-band. The wireless device receives a random access response. The random access response indicates a first backoff indicator indicating a first backoff time interval of the first sub-band. The random access response indicates a second backoff indicator indicating a second backoff time interval of the second sub-band. The wireless device determines a preamble retransmission for the random access procedure. The wireless device selects, as a backoff time interval, a shorter one of the first backoff time interval and the second backoff time interval. The wireless device performs, at a time based on the backoff time interval, a listen-before-talk procedure.

摘要： A wireless device receives one or more radio resource control message comprising configuration parameters of a plurality of cells. An activation command indicating activation of a plurality of secondary cells (SCells) of the plurality of cells is received. A first downlink control information (DCI), comprising a power saving indication bitmap, is received. Each bit of the power saving indication bitmap indicates whether to monitor a downlink control channel on a corresponding activated SCell of the plurality of SCells. The wireless device starts monitoring a downlink control channel of an activated SCell of the activated SCells, in response to a bit, of the power saving indication bitmap, corresponding to the activated SCell, indicating monitoring the downlink control channel. A second DCI is received via the downlink control channel.

摘要： A wireless device receives configuration parameters of a first bandwidth part and a second bandwidth part of an unlicensed cell. An active bandwidth part is switched from the first bandwidth part to the second bandwidth part. A first contention window size determined based on the switching. Based on the first contention window size, a listen before talk procedure is performed for transmission of a transport block in one or more subbands of the second bandwidth part. A transport block is transmitted based on a listen before talk procedure indicating a clear channel.

摘要： A wireless device receives at least one message from a base station. The at least one message comprises uplink configuration parameters for a cell of the base station. The uplink configuration parameters indicate: a first uplink; a second uplink; and a power value for selecting one of the first uplink and the second uplink. The wireless device determines a scaled power value based on: the power value; and a moving speed of the wireless device. The wireless device selects as a selected uplink, one of the first uplink and the second uplink based on the scaled power value. The wireless device transmits a random access preamble via the selected uplink.

摘要： A wireless device receives from a base station, message(s) comprising configuration parameters of a cell. The configuration parameters may comprise BWP parameters of a first BWP and a second BWP, and a timer value associated with a BWP inactivity timer. A first DCI may be received at a first slot. The first DCI may indicate switching to the second BWP as an active BWP. In response to the first DCI, the first BWP may switch to the second BWP as the active BWP. In response to the first DCI, the BWP inactivity timer may be started at a second slot based on the timer value. The second slot may occur after the first slot by an amount of time determined based on a time offset value. A default BWP may be switched to in response to an expiry of the BWP inactivity timer.
