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.

Sidelink demodulation reference signal indication in sidelink control information

A wireless device receives one or more radio resource control (RRC) messages comprising configuration parameters of a cell that indicate: a bandwidth part (BWP) inactivity timer; a plurality of downlink BWPs comprising a first downlink BWP and a second downlink BWP; and a sidelink BWP. The wireless device performs sidelink communication on the sidelink BWP. The wireless device determines whether to switch from the first downlink BWP to the second downlink BWP, based on: expiry of the BWP inactivity timer; and a priority of the sidelink communication.

Bandwidth part switching based on priority level

A wireless device receives, via a search space, a downlink control information (DCI). The DCI includes a cancellation indication (CI) for cancelling uplink signals via uplink resources of an uplink cell. The wireless device determines that one or more sidelink resources, of a scheduled sidelink transmission via a sidelink bandwidth part (BWP) on the uplink cell, overlap with the uplink resources. The wireless device drops a scheduled sidelink transmission, via one or more sidelink resources of a sidelink bandwidth part (BWP), based on a first priority of the scheduled sidelink transmission and a second priority of the CI.

Cancellation indications of uplink and sidelink transmissions

A wireless device receives parameters indicating: a hybrid automatic repeat request (HARQ) round trip time (RTT) timer of a multicast and broadcast service (MBS), and a feedback indicator indicating whether HARQ feedback is enabled. The wireless device receives a group common DCI scheduling a transport block (TB) of the MBS. In response to the feedback indicator indicating that HARQ feedback is enabled, the wireless device transmits a HARQ feedback with a negative value based on the TB being unsuccessfully decoded, starts the HARQ RTT timer after transmitting the HARQ feedback, and monitors, in response to the HARQ RTT timer expiring, a downlink control channel for a retransmission of the TB.

Discontinuous reception operation of multicast and broadcast services

A wireless device receives parameters, including a first discontinuous reception (DRX) configuration associated with unicast transmissions in a cell and a second DRX configuration associated with multicast and broadcast services (MBS) in the cell. The wireless device may also receive a power saving (PS) indication indicating not to start a DRX on duration timer. The PS indication may be applied for the first DRX configuration; and it may not be applied for the second DRX configuration. The wireless device may further skip monitoring, in a first DRX on duration of the first DRX configuration, first physical downlink control channels (PDCCHs) for the unicast transmissions based on receiving the PS indication. The wireless device may also monitor, in a second DRX on duration of the second DRX configuration and while skipping monitoring the first PDCCHs in the first DRX on duration, second PDCCHs for the MBS.

Power saving operation for multicast and broadcast services

A wireless device receives configuration parameters, of a multicast and broadcast service (MBS) session, that indicates a channel state information (CSI) report configuration and a group common identifier. Based on the group common identifier, a downlink control information (DCI) is received that includes a resource indication of a group common physical downlink shared channel (PDSCH) for a multicast transmission of a transport block (TB), and a parameter indicating whether a CSI report is enabled for the MBS session. The TB is received via the group common PDSCH. In response to the parameter indicating that the CSI report is enabled, the CSI report is transmitted based on the CSI report configuration.

Channel state information report for multicast and broadcast services

A wireless device receives configuration parameters comprising pathloss reference linking indicators for SRS resource sets of a first cell associated with one or more TRPs, wherein each SRS resource set of the SRS resource sets comprises SRS resources, and each SRS resource set is associated with a respective pathloss reference linking indicator of the pathloss reference linking indicators, indicating a cell index identifying a pathloss reference cell. The wireless device transmits, via SRS resources of a first SRS resource set of the SRS resource sets in the first cell, SRSs with a transmission power determined based on a first pathloss RS of a first pathloss reference cell, wherein the first pathloss reference cell is indicated by a first pathloss reference linking indicator, of the pathloss reference linking indicators, associated with the first SRS resource set.

Power control for multiple transmission reception points

Wireless devices may communicate with each other, for example, via sidelink communication. A wireless device may receive downlink messages from a base station, and the wireless device may receive sidelink messages from another wireless device. Acknowledgment messages to the base station may be prioritized, based on an indication of a priority, such that a sidelink message may be prioritized over acknowledgment feedback for a downlink message.

Feedback for wireless communications

A base station transmits, to a wireless device, configuration parameters of a control resource set in a bandwidth part (BWP), and the control resource set includes resource block (RB) sets of the BWP. The base station transmits a control information via one or more control channel elements (CCEs) of first CCEs within a first RB set of the RB sets. The base station receives, from the wireless device, a signal via an uplink resource based on an index of a CCE of the one or more CCEs of the first CCEs. The index is determined based on first index values, of the first CCEs within the first RB set, starting from a same initial value as that of index values of CCEs within each respective RB set of the RB sets.

Control channel element indexing for uplink transmission

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.
