Abstract: Embodiments of the present disclosure relate to reporting preconfigured up-link transmission failure. According to embodiments of the present disclosure, the terminal device logs failures associated with transmission on the preconfigured resources and failure causes. The terminal device transmits the logged information to the network device. In this way, the network device is aware of the failure occurrences and their reasons. The network device is able to use the information for configuring uplink resources more efficiently and the resources can be efficiently allocated for other purpose or other terminal devices.

Abstract: Embodiments of the present disclosure relate to mechanism for sharing HARQ processes by multiple configured grant resources. According to embodiments of the present disclosure, multiple configured grant resources share a common pool of HARQ processes. The network device transmits information concerning the multiple configured grants resources and the common pool HARQ process to the terminal device. Further, for one of the multiple configured grant resources, the terminal device selects a HARQ process from the common pool of HARQ processes. In this way, the throughput has improved and the low latency for high priority data is ensured.

Abstract: Embodiments of the present disclosure relate to mechanism for providing multiple transmission opportunities. According to embodiments of the present disclosure, the network device transmits the random access response which includes an indication as to the number of transmission opportunities. If the random access response includes the preamble of the terminal device, the indication as to the number of transmission opportunities is applied to the terminal device. In this way, overheads are saved and the flexibility is improved.

Abstract: Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage medium for selection of a channel access priority. In example embodiments, a subset of data units from a set of data units is selected for multiplexing into a data packet. The selecting is at least in part based on a channel access priority associated with each of the subset of data unit. The subset of data units is multiplexed into the data packet, and then the data packet is transmitted.

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.
