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

A wireless device receives a radio resource control message comprising a first sounding reference signal (SRS) resource set identifier of a first SRS resource set of a serving cell and a second SRS resource set identifier of a second SRS resource set of the serving cell. The wireless device transmits a power headroom report (PHR) medium access control control element (MAC CE) comprising a first field indicating a first power headroom value associated with the first SRS resource set and a second field indicating a second power headroom value associated with the second SRS resource set. The order of the first field and the second field in the PHR MAC CE is based on an ascending order of the first SRS resource set identifier and the second SRS resource set identifier.

Power headroom report for multiple sounding reference signal resource sets

A method may include receiving, by a wireless device and during a random access procedure, a random access response indicating a first backoff time interval of a first sub-band of a cell, and indicating a second backoff time interval of a second sub-band of the cell. The method may include selecting, for a preamble retransmission of the random access procedure, a backoff time interval based on the first backoff time interval and the second backoff time interval. The method may include performing, at a time based on the backoff time interval, a listen-before-talk procedure.

Random access backoff indicator

A wireless device receives one or more configuration parameters indicating a plurality of transmission configuration indicator (TCI) states for uplink transmissions. The wireless device transmits, for a random access procedure, a physical uplink shared channel (PUSCH) transmission with a spatial filter. The wireless device receives a medium access control control element (MAC CE) indicating activation of more than one TCI state of the plurality of TCI states. The wireless device transmits, with the spatial filter used during the random access procedure, one or more uplink signals before receiving a downlink control information (DCI) indicating a TCI state from the more than one TCI state.

Determination of spatial filter for transmissions

Wireless communication techniques using a power saving mode are described. A wireless device may be configured with a plurality of power saving configurations. A base station may transmit an indication of a power saving configuration in the plurality of power saving configurations. The wireless device may monitor a power saving channel based on the indicated power saving configuration.

Activation and deactivation of power saving operation

Wireless communications may be used to support data processing. A plurality of resources may be indicated for a wireless device to use to communicate and/or process data. Data may be received and processed based on groups of the plurality of resources to be used. For example, the plurality of resources to be used may be associated with different resource groups.

Communication and data processing in wireless communications

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 base station may transmit to a wireless device one or more configuration parameters. The one or more configuration parameters indicate: one or more physical uplink control channel (PUCCH) resources, and a default beam is used for physical uplink shared channel (PUSCH) transmissions. The bases station may transmit to the wireless device downlink control information (DCI), with DCI format 0_0, scheduling a PUSCH. The base station may receive from the wireless device, via the PUSCH, a transport block according to a default spatial relation in response to: a DCI format of the DCI being the DCI format 0_0, the configuration parameters indicating that the default beam is used, each PUCCH resource of the one or more PUCCH resources not being configured with a spatial relation, and the wireless device being in a radio resource control (RRC) connected mode.

Default spatial relation for physical uplink shared channel transmissions

Base stations and wireless devices may use cross-slot scheduling for each of a plurality of cells. Base stations and wireless devices may communicate regarding the cross-slot scheduling, including for example, one or more indications associated with cross-slot scheduling for one or more cells. A wireless device may determine cross-slot scheduling for one or more transmissions associated with the one or more cells. The wireless device may save power by switching to a power saving mode for at least one cell during one or more slots, based on the cross-slot scheduling.

Power saving operations for communication systems

A wireless device determines a reference duration for contention window adjustment, wherein the reference duration is from a beginning of a channel occupancy and until an end of a first slot where at least one physical uplink shared channel (PUSCH) is transmitted. The wireless device performs a listen before talk (LBT) procedure with a contention window value associated with the reference duration. The wireless device transmits at least one uplink signal after the LBT procedure indicates a clear channel.

Contention window determination

A base station may transmit, to a wireless device, one or more messages indicating transmission configuration indicator (TCI) states for downlink transmissions. The base station may transmit, to the wireless device, a medium access control control element (MAC CE) activating a plurality of TCI states of the TCI states. The base station may transmit, to the wireless device based on a reference signal identified during a random access procedure and before receiving downlink control information (DCI) indicating a TCI state from the plurality of TCI states, one or more downlink signals.

Default beam for downlink signal transmissions

Wireless communications are described. A base station may send control information for scheduling data to be transmitted to the wireless device via a downlink. The control information may comprise one or more indications of wireless resources to be used by the wireless device to receive the data. The wireless device may receive the data based on one or more determinations/conditions, such as satisfying a time offset (e.g., between reception of the downlink information and a scheduled transmission of the data), whether a control resource set is configured to indicate a transmission configuration state, and/or whether the control information indicates a transmission configuration state.

Methods, systems, and apparatuses for beam management

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 wireless device selects at least two reference signals (RSs) for a random access procedure. A random access preamble is transmitted, for the random access procedure, based on the at least two RSs. A random access response, associated with the random access preamble, is received scheduling a PUSCH transmission. The wireless device transmits: one or more first repetitions, of the PUSCH transmission, with a first transmission power based on a first RS of the at least two RSs; and one or more second repetitions, of the PUSCH transmission, with a second transmission power based on a second RS of the at least two RSs.
