Abstract: Wireless communications using a power saving state are described. A wireless device and/or a base station may provide improved resource management such as by monitoring a reduced resource set in a power saving state. The wireless device may monitor an initial resource set in a non-power saving state and a reduced resource set in a power saving state.

Abstract: A wireless device receives a configuration parameter indicating at least two sounding reference signal (SRS) resource sets of a cell. The wireless device receives a power headroom report (PHR) configuration for the cell. The wireless device transmits a PHR comprising one Type 1 power headroom (PH) value of the cell. The PHR is transmitted based on a parameter, indicating to report two power headroom values of the cell, being absent in the PHR configuration.

Abstract: A wireless device may communicate with a base station. The wireless device may request system information associated with a cell. The cell may be determined to be unavailable, for example, based on system information associated with the cell not being provided after a request for it is made.

Abstract: Beam determination may be used in wireless communications, for example, in a beam failure recovery procedure. One or more parameters may be communicated and/or used to indicate an association between resources and a corresponding control resource set (CORESET) pool index of multiple CORESET pool indices. For each of the multiple CORESET pool indices, a reference signal associated with the CORESET pool index may be determined. Wireless communications may be performed by selecting a reference signal for each of the multiple CORESET pool indices, and resources associated with a corresponding CORESET pool index may be communicated based on the selected reference.

Abstract: Transmission repetition may be used in wireless communications. Control channel repetition may be used for scheduling communications between a base station and a wireless device. A time period between the control channel and the scheduled communications may be less than a threshold time period. The wireless device may determine, for communicating with the base station, a wireless resource corresponding to a default resource pool, a resource pool used for at least one repetition of the control channel, and/or based on a resource pool indicated via the control channel.

Abstract: Wireless resource determination and use are described. A wireless device may determine to use a resource (e.g., PUCCH resource), indicated by control information (e.g., DCI), for sending an acknowledgement (e.g., HARQ-ACK feedback) of a reception of data (e.g., at least one transport block). The control information may be received in a message of a plurality of messages. The wireless device may select the control information (e.g., for determining the resource) from among other control information in the plurality of messages, based on one or more factors.

Abstract: A wireless device receives one or more configuration parameters indicating a time window for controlling a radio link failure indication based on a beam failure recovery procedure. A first failure of the beam failure recovery procedure is determined during the time window. The first failure is ignored by not causing a radio link failure in response to the first failure being during the time window. A second failure of the beam failure recovery procedure after the time window is determined. A radio link failure in response to the second failure is indicated.

Abstract: A wireless device may receive one or more messages comprising one or more configuration parameters for a cell. The cell may comprise a normal uplink (NUL) carrier, a supplementary uplink (SUL) carrier, and a downlink carrier comprising at least two downlink bandwidth parts (BWPs). The wireless device may select, for a random-access procedure of the cell, an uplink carrier among the NUL carrier and the SUL carrier based on a measured quality of each downlink BWP of the at least two downlink BWPs. The uplink carrier may be the NUL carrier based on the measured quality of each downlink BWP of the at least two downlink BWPs being equal or greater than an uplink carrier threshold. The wireless device may transmit, via the NUL, a random-access preamble for the random-access procedure.

Abstract: A base station transmits configuration parameters of a cell to a wireless device. In an embodiment, the configuration parameters include bandwidth part (BWP) parameters of a first BWP and a default BWP, a first timer value associated with a cell deactivation timer, and a second timer value associated with a BWP inactivity timer. The base station may also transmit a downlink control information (DCI) indicating an activation of the cell for the wireless device, to the wireless device. In response to transmitting the DCI, the base station may further activate the cell for the wireless device and start the cell deactivation timer based on the first timer value. In response to activating the cell, the base station may activate the first BWP of the cell for the wireless device. The base station may also start the BWP inactivity timer based on the second timer value.

Abstract: A wireless device may receive downlink control information (DCI) indicating switching to an uplink carrier. The wireless device may determine to transmit a confirmation for switching to the uplink carrier based on whether the uplink carrier is a licensed carrier or an unlicensed carrier. Based on the uplink carrier being the unlicensed carrier, the wireless device may transmit the confirmation after switching to the uplink carrier.

Abstract: One or more parameters may be used to configure wireless communications between a wireless device and a base station. A transmission configuration indication selection field may indicate which of two (or more) resources is to be used for a transmission/reception. A transport block size for a transmission occasion may be determined using one of the resources, and the same transport block size may be used for another transmission occasion using another of the resources, for example, if the transmission configuration indication selection field indicates using two resources or if the transmission configuration indication selection field is absent.

Abstract: A wireless device receives radio resource control (RRC) messages comprising configuration parameters of a multicast and broadcast service (MBS). The configuration parameters indicate: a first feedback operation with hybrid automatic repeat request (HARQ) feedback being enabled; and a second feedback operation with the HARQ feedback being disabled. A group common downlink control information (DCI) comprises a field indicating one of the HARQ feedback being enabled or the HARQ feedback being disabled. The wireless device receives a first group common DCI: scheduling a first transport block (TB) of the MBS; and comprising the field indicating the HARQ feedback being enabled. The wireless device transmits, based on the field indicating the HARQ feedback being enabled, a first HARQ feedback for the first TB.

Abstract: A wireless device may communicate with a base station using transmission resources/schemes. A resource/scheme for transmission/reception may be indicated by a field and/or by an absence of a field in a message that schedules transmission/reception. For example, a spatial domain multiplexing (SDM) scheme may be used, for scheduled transmission/reception, based on a value in a transmission configuration indicator selection field and/or based on an absence of such a field in a message.

Abstract: A wireless device may send or receive data while in an inactive state and transition to a connected state without performing a random-access procedure. If the random-access procedure is skipped, the wireless device may use previously used configurations to communicate with a base station.

Abstract: Wireless communications may comprise transmissions using a beam. A message may comprise one or more indications of a beam and/or type(s) of signals for downlink and/or uplink transmission using the beam. An acknowledgement may be used to indicate reception of the one or more indications and/or a time offset may be used for applying the beam for the downlink and/or uplink transmission.

Abstract: Wireless communications may use one or more devices for transmission and/or reception that may lead to potentially harmful exposure. One or more safety measures may be used for wireless communication devices, such as maximum power exposure (MPE) reporting and/or related operations. An MPE report may use a power headroom report (PHR) to include an uplink transmission power reduction value associated with an MPE threshold.

Abstract: Systems, apparatuses, and methods are described for beam failure recovery in wireless communications. A plurality of candidate beams may be selected for beam failure recovery. After sending a first signal associated with a first candidate beam for beam failure recovery, the wireless device may send a second signal associated with a second candidate beam for beam failure recovery.

Abstract: One or more parameters may be used to configure wireless communications between a wireless device and a base station. A resource may be configured for sounding reference signal transmission/reception between a wireless device and a base station. Transmission power for a sounding reference signal transmission may be based on one or more configuration parameters. A virtual bandwidth part for positioning frequency hopping may be used when frequency hopping takes place outside an active bandwidth part. The transmission power may be based on the virtual bandwidth part.

Abstract: A base station and/or a wireless device may communicate using a plurality of wireless resources. Multiple carriers may be used for a transmission such that portions of the transmission may be transmitted using different carriers. Multiple carrier transmission may be independently configured for each of a plurality of wireless resources.

Abstract: A wireless device may communicate with a base station using transmission occasions. A number of transmission occasions for a transmission/reception may be indicated by a field and/or by an absence of a field in a message that schedules transmission/reception. For example, two physical downlink shared channel transmission occasions may be used, for scheduled transmission/reception, based on a value in a transmission configuration indicator selection field and/or based on an absence of such a field in a message.
