Abstract: Embodiments of the present disclosure relate to mobility for small data transmission (SDT) procedure. The first device, which is in an inactive state and served in a first cell of the second device, performs a session of small data transmission between the first device and the second device. The first device determines whether a potential cell reselection criterion is satisfied when the session of small data transmission is ongoing. If a potential cell reselection criterion is satisfied, the first device transmits, to the second device, first information indicating an intention of cell reselection. As such, if the cell reselection happens during SDT procedure, the second device is able to put the first device into either the inactive state or the connected state. Accordingly, already transmitted data is not lost in case cell reselection happens before the session of small data transmission is completed.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable storage media of communication for BFR. A method implemented at a first device comprises detecting a beam failure for a serving cell of the first device; in accordance with a determination that the beam failure is detected for the serving cell, triggering a procedure for a beam failure recovery for the serving cell; determining whether information related to the beam failure recovery is available for the serving cell; and in accordance with a determination that the information is unavailable, transmitting to a second device a first indication that the beam failure is detected and a second indication that no candidate beam is available. In this way, the full BFR information for the failed serving cells can be acquired finally, and more reliable and faster BFR can be achieved.

Abstract: Embodiments of the present disclosure relate to methods and devices for transmission by selecting between uplink resources. According to a method implemented by a terminal device in a communication system, a configuration of a first resource is received from a network device, the first resource being a grant-free resource. An uplink grant is received from the network device, indicating a second resource for use in a transmission time interval. The terminal device determines, based on the configuration of the first resource, whether the first resource is available in the transmission time interval. In response to determining that the first resource is available and possibly in response to a predefined condition associated with a logical channel for the terminal device is met, the terminal device transmits uplink data to the network device using the first resource.

Abstract: Embodiments of the present disclosure relate to random access in a communication system. A first device determines whether a contention-free random access resource is allocated from a second device for a first random access type. In accordance with a determination that the contention-free random access resource is allocated, the first device compares a target transport block size corresponding to the contention-free random access resource with a first transport block size configured for a first group of preambles available for the first random access type, and performs random access to the second device based on a result of the comparison.
