Abstract: A wireless device may receive message(s) comprising configuration parameters of cells grouped into a first cell group and a second cell group. One or more first grants for transmission in a first subframe on one or more first cells of the first cell group are received. The one or more first cells may comprise an LAA cell. One or more second grants for transmission in a second subframe on one or more second cells of the second cell group may be received. The first subframe may overlap the second subframe. The first subframe may lead the second subframe by a timing difference. In response to the timing difference being larger than a timing value, a power scaling rule may be applied to transmissions corresponding to the one or more second grants based on whether a listen before talk procedure indicates a clear channel for the LAA cell.

The first DCI comprises: a first trigger field indicating that the first DCI is triggered in response to a second DCI indicating a second trigger; and a field indicating a validation duration for receiving the second DCI via a cell. A discontinuous reception (DRX) process determines that a medium access control (MAC) entity is not in an Active Time. The MAC entity, during at least a portion of the validation duration, monitors a control channel for the second trigger on the cell even if the MAC entity is not in the Active Time.

The wireless device receives an uplink grant indicating radio resources of a first radio resource type. The wireless device constructs a transport block comprising the BSR. The wireless device transmits the transport block via the radio resources of the first radio resource type.

A first downlink control information (DCI) indicating a first resource assignment for the first SPS may be received. A second DCI indicating a second resource assignment for the second SPS may be received. A first transport block (TB) associated with a first HARQ process identifier may be transmitted, employing the first resource assignment. A second TB associated with a second HARQ process identifier may be transmitted, employing the second resource assignment.

Abstract: A wireless device receives message(s) comprising configuration parameters for a cell. A first DCI is received in a first TTI and comprises: a first field indicating a first resource block assignment; and a first trigger field indicating whether the first DCI is a first triggered DCI. A second DCI is received in a second TTI and comprises: a second field indicating a second resource block assignment; and a second trigger field indicating whether the second DCI is a second triggered DCI. A third DCI is received in a third TTI via a common control channel of the cell and comprises a third trigger field indicating a trigger. The first DCI or the second DCI may be selected as a selected DCI at least based on a relative start time of the first TTI and the second TTI.

Abstract: A wireless device receives, in a first subframe, a first DCI comprising: a first field indicating an assignment of resource blocks for transmissions via an uplink subframe of an LAA cell; and a first trigger indicating that the first DCI is triggered in response to a second DCI indicating a second trigger. Timing of the uplink subframe is determined based at least on the second DCI. Power headroom values of a reference subframe for transmission via the resource blocks of the uplink subframe of the LAA cell are determined. The reference subframe is different from the uplink subframe. The reference subframe is a subframe after a predetermined number of subframes from the first subframe. A second DCI is received. A transport block comprising a power headroom report comprising the power headroom values of the reference subframe is transmitted, via the uplink subframe of the LAA cell.

Abstract: A received first DCI comprises: a first trigger field (indicating that the first DCI is triggered in response to a second DCI comprising a second trigger), a validation field (indicating a validation duration for receiving the second DCI validating the first DCI), a hybrid retransmission request (HARQ) identifier field, and a new data identifier (NDI) field. TBs are created in response to the first DCI. In response to monitoring not detecting the second DCI: the first DCI is invalidated and transmission of TBs dropped; the HARQ process ID and the NDI are stored; and the first TBs are stored in a HARQ buffer. A third DCI indicating a same value of the HARQ process ID is received. Uplink signals are transmitted in response to the third DCI. The stored NDI are employed to determine an adaptive-retransmission of the TBs or a new transmission of second TBs.
