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.

A wireless device determines uplink precoders for a transmission of a transport block. The transmission of the transport block take place via uplink resources comprising sub-bands. The uplink precoders for each respective sub-band of the sub-bands are based on a transmission precoder of one or more sounding reference signal (SRS) resources transmitted via each of the respective sub-bands.

Coverage enhancement with frequency selective transmission

A wireless device may receive one or more configuration messages indicating a plurality of resource pools. The wireless device may further measure a plurality of channel busy ratios (CBRs) for the plurality of resource pools based on a CBR measurement window size. The wireless device may also compare the measured CBRs between resource pools by applying a weighting factor. In an embodiment, the weighting factor may be determined based on a relative size of each resource pool of the plurality of resource pools. The wireless device may further select a resource pool for a sidelink transmission among the plurality of resource pools based on the comparing and transmit one or more transport blocks based on a determined transmission parameter.

Enhanced congestion control mechanism for sidelink

A wireless device receives a message configuring one or more time intervals for transmitting coordination information to a second wireless device, where the coordination information indicates a set of resources for one or more sidelink transmissions by the second wireless device. The wireless device selects, from the one or more time intervals, a time interval based on at least a priority level of the one or more sidelink transmissions. The wireless device transmits, to the second wireless device, first coordination information indicating a first set of resources for the one or more sidelink transmissions. The wireless device transmits, to the second wireless device and based on the time interval, second coordination information indicating a second set of resources for the one or more sidelink transmissions.

Sidelink coordination information transmissions/receptions

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 receives one or more messages indicating transmission resource pools of a sidelink, where the transmission resource pools comprise a first transmission resource pool and a second transmission resource pool. In some cases, the wireless device is allowed to use the second transmission resource pool based on one or more thresholds associated with sidelink transport blocks. Based on a transport block meeting the one or more thresholds, the wireless device selects one or more sidelink resources from the second transmission resource pool. The wireless device transmits the transport block via the one or more sidelink resources.

Sidelink resource pool selection for urgent packet transmission

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

Downlink signals, such as synchronization signals and/or reference signals, may be used for facilitating communications between communication devices. The downlink signals may be dynamically reconfigured, for reduced resource consumption, using control channel signaling with reduced resource overhead. Reconfiguration of downlink signals may be based on determined traffic volume in the communication network to minimize any impact of the reconfiguration on network performance.

Dynamic signaling for energy saving in wireless communications

Wireless communications are described for sidelink congestion control. Sidelink congestion control may be performed based on a processing capability of a wireless device and/or sidelink subcarrier spacing.

Sidelink congestion control

A first wireless device receives, from a second wireless device, one or more configuration messages comprising a sidelink latency upper bound for sidelink channel state information (CSI) reporting. The first wireless device receives, from the second wireless device and during a time slot, a sidelink CSI reporting triggering indication via a physical sidelink shared channel. The first wireless device determines, based on receiving the sidelink CSI reporting triggering indication, one or more sidelink CSI reporting resources within a time period indicated by: the sidelink latency upper bound and starting from the time slot. The first wireless device transmits one or more sidelink CSIs on the one or more sidelink CSI reporting resources.

Sidelink channel state information acquisition

A wireless device receives one or more radio resource control (RRC) messages that indicate uplink transmission configuration indicator (TCI) states associated with cancellation indications (CIs). The wireless device receives a first DCI scheduling a transmission via uplink resources and indicating a first uplink TCI state. The wireless device receives a second DCI that includes a cancellation indication (CI) indicating cancellation resources that overlaps with the uplink resources. The wireless device drops the transmission via the uplink resources in response to the uplink TCI states including the first uplink TCI state of the transmission.

Preemption indication with multi-beam

A session management function (SMF) receives, from a wireless device, a packet data unit (PDU) session establishment request message requesting establishment of a PDU session associated with an application and offloaded processing of data from the wireless device to an application server associated with the application. The SMF sends, to the wireless device, a response message indicating a rejection or an acceptance of the offloaded processing of data.

Session management for edge computing

A wireless device may receive, from a base station, one or more radio resource control (RRC) messages. The one or more RRC messages may indicate a plurality of demodulation reference signal (DMRS) patterns and a length of a DMRS for each of the plurality of DMRS patterns. The wireless device may determine a DMRS pattern of a physical sidelink shared channel (PSSCH) based on the plurality of DMRS patterns and the length of the DMRS in the DMRS pattern. The wireless device may transmit, to a second wireless device, sidelink control information (SCI) indicating the DMRS pattern of the PSSCH and a number of one or more antenna ports for the DMRS in the DMRS pattern.
