A wireless device receives a radio resource control (RRC) message indicating a first resource pool of a sidelink (SL) communication. The wireless device determines, from a candidate resource set in the first resource pool, a SL grant indicating resources for one or more SL transmissions of the SL communication. The wireless device receives, by a medium access control (MAC) layer from a physical layer of the wireless device, an indication of SL listen before talk (LBT) failure of a first resource of the resources indicated in the SL grant. Based on the indication, the wireless device selects, for the first resource, a second resource from the first resource pool excluding resources associated with SL LBT failure. The wireless device transmits, via the second resource, the one or more SL transmissions of the SL communication.

Slidelink transmission method and apparatus based on sidelink listen-before-talk failure on a shared spectrum

A wireless device receives one or more messages indicating reference downlink control information (DCI) formats, wherein each of the reference DCI formats is for a respective of one of downlink bandwidth parts (BWPs) of a scheduling cell. The wireless device receives, via a first downlink BWP of the downlink BWPs, a sidelink DCI including one or more fields and a quantity of predefined values. The quantity is based on a size of a reference DCI format, of the reference DCI formats, corresponding to the first downlink BWP.

Sidelink downlink control information configuration

A wireless device may receive from a base station a first downlink control information (DCI) scheduling a physical downlink shared channel (PDSCH) transmission. The first DCI may indicate that the wireless device is not to transmit feedback for the PDSCH transmission before receiving a second DCI and a PDSCH group index. The second DCI may indicate a time slot for transmitting feedback and the PDSCH group index. In response to the wireless device receiving the second DCI and based on the second DCI indicating feedback for the same PDSCH group index as the first DCI, the wireless may transmit to the base station, in the time slot indicated, the feedback for the PDSCH transmission.

Scheduling physical downlink shared channel feedback

A destination wireless device receives, from a base station, configuration parameters of physical sidelink feedback channel (PSFCH) radio resources. The destination wireless device receives, from a source wireless device, sidelink control information comprising an identity (ID) of the source wireless device. The destination wireless device transmits, to the source wireless device, an acknowledgement for a transport block via a PSFCH radio resource having an index. The index is based on: the ID of the source wireless device, an ID of the destination wireless device, and a modulo operation performed on a quantity of the PSFCH radio resources.

Feedback resource

A wireless device receives downlink control information (DCI) comprising one or more fields set to one or more values. The wireless device validates, based on the one or more values, the DCI as an activation or a release of a configured grant of a bandwidth part (BWP) of BWPs of a cell. The wireless device transmits, based on validating the DCI, a confirmation of receiving the DCI, wherein the confirmation comprises an identifier of the BWP and an identifier of a sub-band of a plurality of sub-bands of the BWP.

Configured grant processes for wireless devices

A method may include receiving, by a wireless device, one or more configuration parameters for a timing advance (TA) reporting procedure. The one or more configuration parameters may include a first timing advance threshold for a TA reporting based on an offset between a current timing advance value and a last reported timing advance value. The method may also include triggering the TA reporting procedure based on a condition for the first timing advance threshold being satisfied. The method may additionally include based on the triggering the TA reporting procedure, triggering a scheduling request (SR) and starting a SR prohibit timer. The method may further include, in response to canceling the TA reporting procedure, cancelling the triggered SR and stopping the SR prohibit timer.

Reporting timing advance information in non-terrestrial networks

A wireless device receives one or more parameters indicating a plurality of sidelink carriers, a discontinuous transmission (DTX) threshold value, and a channel busy ratio (CBR) threshold value for a sidelink carrier selection procedure. The wireless device selects one or more first sidelink carriers from the plurality of sidelink carriers. The wireless device determines that the number DTXs on at least one sidelink carrier is equal to the DTX threshold value. Based on the determining, the wireless device triggers the sidelink carrier selection procedure and transmits a message indicating the at least one sidelink carrier. The wireless device selects, during the triggered sidelink carrier selection procedure and based on a CBR being below the CBR threshold value, a third sidelink carrier from the plurality of sidelink carriers. The wireless device transmits, to the second wireless device, a sidelink transport block (TB) via the third sidelink carrier.

Sidelink radio link failure based on carrier reselection

A first wireless device receives, from a second wireless device, sidelink control information comprising a field with a value indicating to transmit a report message comprising preferred radio frequency resources of a sidelink between the first wireless device and the second wireless device. In response to the value of the field indicating to transmit the report message, the first wireless device transmits, to the second wireless device and via a physical sidelink shared channel of the sidelink, the report message indicating radio frequency resources preferred by the first wireless device. The first wireless device receives, from the second wireless device, sidelink transport blocks via one or more resources of the preferred radio frequency resources.

Measurement information feedback reporting

A wireless device receives a sidelink control information (SCI) that may schedule a transport block and may also indicate a first repetition value. The wireless device may also receive a transport block via a physical sidelink shared channel (PSSCH). Based on a comparison of the first repetition value received via the SCI and a repetition threshold, the wireless device may determine to transmit an acknowledgment for the received transport block. The wireless device may then transmit the acknowledgment for the received transport block.

Hybrid automatic repeat request feedback in radio systems

A wireless device receives a configured grant (CG) configuration indicating: a period of the CG configuration, and a number of consecutive slots for transmission occasions within the period. The wireless device transmits uplink data, via a transmission occasion of the transmission occasions. A hybrid automatic repeat request (HARQ) process index (ID) for transmission of the uplink data is based on: the number of consecutive slots for the transmission occasions within the period, and an offset for the transmission occasion of the transmission occasions within the period. The offset is based on an order of the transmission occasion among the transmission occasions within the period.

Hybrid automatic repeat request process for configured grant

A first wireless device receives, from a second wireless device, a first medium access control (MAC) control element (CE) requesting for an inter-UE coordination between the first wireless device and the second wireless device, wherein the first MAC CE indicates a start time and an end time of a selection window for a resource selection procedure of the second wireless device to select resources for one or more sidelink transmissions by the second wireless device. The first wireless device selects a preferred resource set or a non-preferred resource set during the selection window. The first wireless device transmits, to the second wireless device, a second MAC CE indicating the preferred resource set or the non-preferred resource set for the second wireless device to select resources for the one or more sidelink transmissions. The first wireless device receives the one or more sidelink transmissions.

Resource selection window for sidelink inter-UE coordination

A first wireless device determines a number of sidelink slots configured in a sidelink resource pool. The first wireless device determines a second reservation period in units of slots based on a first reservation period in milli-second (ms) and the number of sidelink slots. The first wireless device transmits a transport block via one or more transmission resources selected based on the second reservation period.
