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 configuration parameters indicating one or more radio network temporary identifiers (RNTIs) to monitor, via downlink control channels, during an active time of DRX operation. The wireless device selects, for transmission of a message-A of a random access procedure, one or more resources, where the message-A comprises a preamble and a payload and the payload comprises a C-RNTI. The wireless device starts a response window based on transmitting the preamble via at least one resource of the one or more resources. Based on dropping transmission of the payload and during the response window, the wireless device monitors the downlink control channels for a first RNTI, where the first RNTI is associated with a response to the preamble and determined based on the at least one resource, and does not monitor the downlink control channels for the one or more RNTIs.

Two-step random access procedure with discontinuous reception

A wireless device may receive a first downlink control information (DCI) associated with scheduling resources for a transport block (TB) and indicating a first transmission configuration indicator (TCI) state from a first TCI state pool. The wireless device may further receive a second DCI indicating a second TCI state from a second TCI state pool. Based on the first TCI state being from the first TCI state pool and the second TCI state being from the second TCI state pool that is different from the first TCI state pool, the wireless device may receive the TB via the resources and based on the second TCI state.

Transmission and reception with multiple beams

A wireless device selects, in response to initiating a random access procedure, a first radio resource for transmitting a message. In response to determining the first radio resource is invalid for transmission of the message, the wireless device transmits, via a second radio resource, the message based on determining the second radio resource is valid for the transmission of the message and determining a time difference between the second radio resource and the first radio resource is smaller than a threshold.

Two step random access in non-terrestrial networks

Wireless communication techniques for power saving are described. A wireless device may be configured with one or more power saving configurations, such as a dormant state. During a dormant state, downlink channel monitoring (e.g., on a secondary cell) may be stopped and/or a beam failure recovery procedure may be performed.

Beam failure recovery in a power saving operation

A wireless device receives a layer 1 or layer 2 triggered mobility (LTM) cell switch command. The LTM cell switch command comprises a configuration index indicating a cell for an LTM procedure and does not comprise a timing adjustment value for a primary timing advance group (PTAG) of the cell. In response to receiving the LTM cell switch command with no timing adjustment value, the wireless device starts a time alignment timer associated with the PTAG after measuring a timing advance of the cell.

Timing advance for mobility

Wireless communications are described. A wireless device and/or a base station may determine/select one or more beams for transmission of signals (e.g., sounding reference signals, SRSs) in one or more cells. The wireless device and/or the base station may determine/select a beam based on one or more of: cell indicators of a first cell and/or a second cell, antenna panel indicators associated with SRS transmissions, priorities of SRS transmissions, resource set indicators corresponding to the SRS transmissions, and/or other information.

Methods, devices, and apparatuses for beam management

Wireless communication techniques using search space sets are described. A downlink channel may be monitored using search space sets based on one or more conditions. For example, a downlink channel may be monitored on a first search space set during a first time period (e.g., before an expiration of a timer) and/or a downlink channel may be monitored on a second search space set during a second time period (e.g., after an expiration of a timer).

Downlink monitoring using search space sets

A wireless device may receive one or more configuration parameters indicating entries of a time domain resource allocation table and one or more scheduling offsets. Each entry of the entries may comprise a respective slot offset. The wireless device may receive downlink control information (DCI) indicating a first entry of the entries and a first scheduling offset of the one or more scheduling offsets. The wireless device may receive downlink data in a first slot determined based on a slot offset of the first entry and the first scheduling offset.

High frequency time domain resource allocation

Control information may be used to schedule communications between a wireless device and a base station. The wireless device may monitor control channels associated with one or more cells to receive the control information.

Scheduling wireless communications

A wireless device receives one or more messages indicating a first transmission occasion for a physical uplink control channel (PUCCH) resource and indicating a second transmission occasion for the PUCCH resource. The wireless device receives downlink control information (DCI) indicating a transmission configuration indicator (TCI) state and indicating the PUCCH resource. The wireless device skips transmission, via the first transmission occasion of the PUCCH resource and based on a first listen before talk (LBT) procedure indicating a busy channel on the first transmission occasion, of an acknowledgment of the receiving the DCI indicating the TCI state. The wireless device transmits, based on a second LBT procedure indicating an idle channel on the second transmission occasion, the acknowledgment via the second transmission occasion of the PUCCH resource.

Beam management procedures with shared spectrums

Wireless communications may comprise one or more random access procedures. A random access procedure may be associated with a buffer status report (BSR). The BSR report may be maintained based on one or more conditions associated with the RA procedure, such as awaiting a random access response, an ongoing RA delay trigger timer, and/or transmission of the BSR.

Random access associated with buffer status reporting

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 wireless device receives one or more messages comprising a parameter indicating a first value of a listen before talk (LBT) counter. The LBT counter is incremented based on an LBT procedure indicating an LBT failure for an uplink transmission via a first bandwidth part. Based on the LBT counter reaching the first value, a switch is made from the first bandwidth part to a second bandwidth part as an active bandwidth part.

Cell and bandwidth part operations in unlicensed bands

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 be sent based on MPE detection and one or more messages, such as for cell activation, bandwidth part (BWP) or other wireless resource activation and/or switching, and/or a discontinuous reception (DRX) or other state transition.
