Abstract: Embodiments of the present disclosure relate to reporting beam failure. A terminal device detects a beam failure on one or more serving cells of the terminal device. If the beam failure is detected on the one or more serving cells, the terminal device obtains information concerning one or more candidate beams and the one or more serving cells. Each of the one or more candidate beams is associated with a respective one of the one or more serving cells. The terminal device then transmits at least a portion of the information to a network device associated with the one or more serving cells.

Abstract: In accordance with some embodiments, an apparatus may include at least one processor and at least one memory including computer program code. The at least one memory and the computer program code can be configured to, with the at least one processor, cause the apparatus to at least receive at least one random access preamble from user equipment. The at least one memory and the computer program code can be further configured to, configure at least one backoff indicator. The at least one memory and the computer program code can be further configured to, with the at least one processor, cause the apparatus to at least transmit the at least one backoff indicator and at least one backoff configuration indicator to the user equipment. The at least one backoff configuration indicator is used to indicate how the at least one backoff indicator is applied.

Abstract: When a time domain collision between Tracking Reference Signal (TRS) symbols and downlink shared data channel symbols is detected, the TRS symbols may be multiplexed with the downlink shared data channel symbols from multiple Transmission Reception Points (TRPs) not sharing quasi co-location (QCL) parameters with each other. If a time domain collision between TRS symbols and dynamically or semi-static (e.g., persistent) downlink shared data channel transmissions is detected, transmission and/or reception of the TRS and/or the downlink shared data channel may be adjusted.

Abstract: Examples of the disclosure relate to management of Transmission Configuration Indicator (TCI) States. In examples of the disclosure a User Equipment (UE) can be arranged to receive an indication of a plurality of candidate TCI states. The plurality of candidate TCI states comprise at least one TCI state different to the TCI state with which the UE is currently configured. The UE can also be arranged to transmit an indication of a selected TCI state from the plurality of candidate TCI states where the selected TCI state is different to the TCI state with which the UE is currently configured. The indication of the selected TCI state can be transmitted to a gNB or access node. The transmission of the selected TCI state uses one of a hybrid automatic repeat request (HARQ) acknowledgement (ACK) and an ACK transmission.

Abstract: An method includes determining, by a user device, a configuration for a plurality of beam failure detection reference signal (BFD-RS) sets, and a candidate beam set associated with each of the plurality of (BFD-RS) sets; determining, by the user device, a beam failure status of the plurality of (BFD-RS) sets, including determining a beam failure for at least one of the (BFD-RS) sets; adjusting at least one of the following based on the beam failure status of the plurality of (BFD-RS) sets: a candidate beam evaluation period to evaluate candidate beams of an associated candidate beam set after a beam failure of one of the (BFD-RS) sets; a beam failure detection evaluation period for the user device to detect a failure of one of the (BFD-RS) sets; and scheduling restrictions that restrict or not restrict occasions in which the user device is required to monitor a downlink control channel.
