    Abstract: Methods, apparatus, and systems for a beam failure recovery on one or more secondary cells are described. In one example aspect, a wireless communication method includes receiving, by a first device, parameters configured to carry out beam failure detection and beam failure recovery for secondary cells associated with the first device, determining, by the first device, whether a beam failure event has occurred on at least one of the secondary cells based on at least one of the parameters, performing, upon a determination that the beam failure event has occurred, a beam failure recovery procedure for the secondary cell with the beam failure event, and terminating the beam failure recovery procedure upon an occurrence of a termination event.

    Abstract: This disclosure relates generally to wireless communications and, more particularly, to systems and methods for dynamic configuration of a packet duplication convergence protocol (PDCP) configuration. In one embodiment, a method performed by a communication device includes: receiving configuration information from a communication node; and determining, for a packet duplication protocol per data radio bearer, a number of copies or a logical path based on the configuration information.

    Abstract: Techniques are described to adjust transmission rates. For example, in a dual-connectivity system, a first communication node can be in communication with a first network node and a second network node. The first communication node may receive from a first network node a first message that includes a recommended bit rate for an ongoing communication between the first communication node and a second communication node. In some embodiments, the first communication node can, in response to receiving the first message, send an acknowledgment or a non-acknowledgment indicator to the first network node indicating that the first communication node accepts or rejects the recommended bit rate.

    Abstract: Some techniques for efficiently indicating a mapping relationship from physical random access channel preambles and/or random access resource specific to one or more system information blocks in a wireless communication network are described. One example method includes transmitting, from a network node, a message that identifies a number of random access preambles that are reserved for transmissions of system information requests by mobile devices.

    Abstract: The disclosed techniques enable communication nodes to perform rate adjustments. As an example, a communication node may receive a control information from a network node. Based on the received control information, the control node may determine that the network node supports codec adaptation or that the communication node is allowed to enable the codec adaptation.
