Abstract: 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.

Abstract: Embodiments of the present disclosure relate to random access in a communication system. A first device receives a criterion to select a random access type for performing random access to a second device. The first device further determines whether the first device is allocated a contention-free random access resource for a certain random access type, and then performs the random access to the second device based on the determination and conditionally based on the criterion. As such, in the case where contention-free random access resource has been allocated for a certain random access type, the device can conditionally apply the criterion for selection of the random access type and can thus perform random access with improved efficiency.

Abstract: Embodiments of the present disclosure relate to mechanism for interactions for entering into the sleep mode. According to embodiments of the present disclosure, the network device transmits the information of go-to-sleep, GTS, to the terminal device on a lower layer (for example, the physical layer). The lower protocol layer informs the higher protocol layer (for example, the MAC layer) of the information of GTS. The terminal device determines how to monitor the physical downlink channel based on the information of GTS. Further, the terminal device may switch bandwidth part based on the information of GTS. In this way, the GTS is able to significantly save power.

Abstract: There is disclosed an apparatus. The apparatus comprises means for using a first random access type in a random access procedure; and in response to determining that a threshold number of failed random access attempts has been reached using the first random access type, determining whether to switch to using a second random access type which is different from the first random access type.

Abstract: Embodiments of the present disclosure relate to a device, a method, an apparatus and a computer readable storage medium for bandwidth part (BWP) switching. In example embodiments, a method is provided. The method comprises determining, at a terminal device, whether continuous Listen-Before-Talk (LBT) failures occur on a first bandwidth part (BWP), the terminal device operating on the first BWP. The method further comprises in response to the continuous LBT failures occurring on the first BWP, switching to a second BWP different from the first BWP. Instead of triggering a re-establishment procedure once continuous LBT failures are detected, switching to another BWP on different LBT sub-channels can be much more efficient than going through the whole re-establishment and reconfiguration procedures.

Abstract: Embodiments of the present disclosure relate to uplink control information for uplink information based on wake-up signals. According to embodiments of the present disclosure, the terminal device determines based on transmission information at a first time point whether a predetermined number of the one or more occasions overlaps with active time of the terminal device. The terminal device determines the configuration for transmitting the uplink information based on the determination. In this way, ambiguity has been reduced and the flexibility of the network is improved.

Abstract: Apparatuses, methods and software for configured grant operation are provided. The first apparatus comprises at least one processor; and at least one memory including computer program codes; the at least one memory and the computer program codes are configured to, with the at least one processor, cause the device at least to transmit a transport block of a HARQ process on preconfigured resources for an uplink transmission to a second apparatus while starting a first timer and a second timer for the HARQ process, wherein the first timer indicates a time period during which the transport block is able to be retransmitted, and wherein the second timer is configured to expire before the first timer; monitor a response associated with the transport block from the second apparatus; and in response to the second timer expiring before receiving the response and before expiry of the first timer, retransmit the transport block while restarting the second timer.

Abstract: Embodiments of the present disclosure relate to a method for confirming uplink semi-persistent scheduling deactivation and a terminal device. In example embodiments, an indication of uplink semi-persistent scheduling deactivation is received from a base station while the terminal device stores data available for uplink transmission. Then, confirmation of the deactivation is sent to the base station. Such confirmation of the deactivation may notify the base station that the terminal device has received the indication of the uplink semi-persistent scheduling deactivation and further that the uplink semi-persistent scheduling will be deactivated at the terminal device.

Abstract: Various communication systems may benefit from an enhanced radio link control status report. A method may include determining a negative acknowledgment sequence number range. The negative acknowledgment sequence number range may include a plurality of consecutive radio link control missing sequence numbers. The method may also include determining at least one of a en negative acknowledgment end sequence number when the plurality of consecutive radio link control missing sequence numbers exceeds the negative acknowledgment sequence number range. In addition, the method may include sending a radio link control status report comprising at least one of a negative acknowledgment sequence number, the negative acknowledgment sequence number range, or the negative acknowledgment end sequence number when the plurality of consecutive radio link control missing sequence numbers exceeds the at least one negative acknowledgment sequence number range.
