Example embodiments of the present disclosure relate to reporting beam failure. A terminal device performs beam failure detection on a first number of serving cells configured for the terminal device. The terminal device determines information to at least indicate respective results of the beam failure detection on a second number of serving cells among the first number of serving cells, where the second number is smaller than the first number. The determined information is transmitted by the terminal device to a network device serving the terminal device using a resource allocated for the terminal device. Based on the information, the network device determines an overall result of the beam failure detection performed on the first number of serving cells.

Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may receive a feedback configuration for providing feedback for downlink communications from a base station. Based on the feedback configuration, the UE may determine whether one or more feedback processes has a multicast-only configuration for multicast data communications, or a multicast-or-unicast configuration for either multicast data communications or unicast data communications. The UE may decode one or more transmissions associated with the one or more feedback processes based on the multicast-only or multicast-or-unicast configuration, and may determine a feedback codebook based on the multicast-only or multicast-or-unicast configuration of the one or more feedback processes. The UE may monitor for retransmissions of one or more multicast data communications based on the feedback process configuration.

This disclosure provides a bearer configuration method for RRC connection reestablishment, a terminal, and a network device. The method in this disclosure includes: when receiving an RRC reestablishment complete message sent by a terminal, determining a Packet Data Convergence Protocol PDCP type supported by a target network to be accessed by the terminal, where the PDCP type includes type-1 PDCP supporting a first network or type-2 PDCP supporting a second network; and reconfiguring bearers in a subsequent RRC process based on the determined PDCP type.

The present disclosure provides a method and a device for non-IP data delivery in a communication system. The method for operating data by a network exposure node includes: receiving a request for operating the data; operating the data according to the request. The data includes a plurality of pieces of non-internet protocol data delivery (NIDD) data, which are buffered in a network and not delivered. The plurality of pieces of data already sent to the network exposure node may still be operated, for example cancelled or replaced, thus undesired actions of the UE may be better avoided.

A wireless communication network serves a Protocol Data Unit (PDU) session type over a Radio Access Network (RAN). The wireless communication network comprises a Network Repository Function (NRF), Management and Orchestration (MANO) system, a User Plane Function (UPF), a RAN, and User Equipment (UEs). The NRF receives UPF requests for User Plane Functions (UPFs) that can serve the PDU session type over the RAN and responsively transfers UPF responses indicating other UPFs that cannot serve the PDU session type over the RAN. The NRF determines when the transfer of the UPF responses is excessive. In response, the NRF transfers an instantiation request to a Management and Orchestration (MANO) system to instantiate a new UPF that can serve the PDU session type over the RAN. The MANO system instantiates the new UPF. The new UPF serves the PDU session type to the UEs over the RAN.
