摘要： Wireless communication systems using random access procedures are described. One or more downlink control messages may indicate a system frame number corresponding to a random access preamble. The one or more downlink control messages may indicate the system frame number using a radio network identifier. The one or more downlink control messages may indicate the system frame number in a field.

摘要： Wireless communication techniques for priority services are described. An access node may transmit, to another access node, data corresponding to a wireless device. The access node may transmit the data along with downlink resource information indicating a radio resource. The other access node may use the radio resource to transmit the data to the wireless device. The access node may transmit one or more preemption indications to one or more other communication devices to preempt any other transmissions in the radio resource.

摘要： Beam failure recovery (BFR) procedures for wireless communications are described. A wireless device may receive a scheduling request configuration for a first cell that indicates uplink resources dedicated to BFR of a second cell and/or uplink resources configured for scheduling requests. A beam failure for a second cell may occur at a time that the wireless device has no uplink resources dedicated to BFR. The wireless device may use (e.g., based on a type of data or resource) an uplink resource configured for scheduling requests to report the BFR.

摘要： Wireless communications and beam failure recovery are described. A wireless device may send one or more messages associated with a beam failure recovery for a cell. The one or more message may comprise an indication that the wireless device has not selected a candidate beam for the cell. The wireless device may receive a response and determine that a beam failure recovery procedure has successfully completed.

摘要： Systems, apparatuses, and methods are described for wireless communications. Wireless communications between a base station and one or more wireless devices are described. A wireless device may use power ramping for transmissions and/or retransmissions. Power ramping may be used during a random access procedure. A wireless device may fail a listen before talk procedure before sending a preamble or a transport block on an unlicensed band. The wireless device may use power ramping to determine a power of transmission of the preamble and/or transport block based on the prior preamble or a transport block transmission. Power ramping may be determined using a power ramping counter value and/or a power ramping step value, which may be shared or associated with the preamble and/or a transport block.

摘要： Beam failure recovery (BFR) procedures are described for wireless communications. A base station may send a message to a wireless device during a BFR procedure. The message may comprise one or more BFR configuration parameters and/or reconfigure one or more BFR configuration parameters. The wireless device may stop the BFR procedure, for example, after or in response to receiving the message from the base station. The wireless device may initiate a second BFR procedure using one or more of the BFR configuration parameters received in the message.

摘要： Wireless communications are described. A wireless device and/or a base station may provide improved resource management. A base station may configure and/or transmit a beam failure recovery medium access control control element (BFR MAC CE) to a wireless device to configure particular cells to use particular assigned candidate beams from a pool of shared candidate beams during beam failure recovery operations. The BFR MAC CE may provide orthogonality in beams that may be designated for use by active cells out of a shared pool of beams that may not be orthogonal across all potentially available cells.

摘要： Beam failure recovery procedures (BFR) are described for wireless communications. At least one transmission for a BFR procedure may overlap with a scheduled transmission. A wireless device may prioritize a transmission for a BFR procedure, for example, by dropping the scheduled transmission and transmitting the at least one transmission the BFR procedure.

摘要： Systems, apparatuses, and methods are described for wireless communications. Packet data convergence protocol (PDCP) packet duplication may be configured for a bearer of a wireless device. The bearer may use various cells to send packets. A base station central unit and/or a base station distributed unit may configure the cells for the bearer based on various types of information.
