Abstract: Embodiments of the present disclosure relate to mechanism for first random access mode falling back to second random access mode. According to embodiments of the present disclosure, the fallback to second random access mode is indicated in messageB and the user equipment only needs to monitor the messageB for the quick mode on the downlink control signal which is addressed to an identifier. The user equipment does not need to monitor the downlink control channel for the second random access mode. In this way, the user equipment is allowed to fall back to the second random access mode without further retry of the quick node, thereby reducing overload and latency.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable mediums for beam failure recovery. The method includes detecting a beam failure on a serving cell of the terminal device, the serving cell including at least one of a primary cell and a secondary cell serving the terminal device. The method further includes in response to detecting the beam failure on the serving cell, generating a medium access control, MAC, control element, CE, the MAC CE including a field associated with the serving cell, wherein the field is set to be a predefined value indicating the beam failure. The method further includes transmitting the MAC CE to a network device associated with the serving cell.

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.

Abstract: In example an embodiment, according to the method, a timer is started to monitor selection of a RA resource in response to a RA procedure for accessing a network device being initiated. The timer is configured with expiration time. The timer is stopped in response to a RA resource being selected for transmitting a RA preamble to the network device. A preamble transmission counter is incremented in response to the timer expiring. The preamble transmission counter records the number of transmitted RA preambles. A failure of the RA procedure is indicated in response to the incremented preamble transmission counter exceeding a threshold. The embodiment enables completion of the RA procedure regardless of an out of coverage situation where no beam is available to be selected for transmitting a RA preamble.

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.
