Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A terminal device receives, from a first network device, a conditional reconfiguration for a set of candidate cells, the conditional reconfiguration comprising information indicating that a subsequent conditional cell change is enabled for at least one candidate cell in the set of candidate cells. If a cell change or addition is performed based on the conditional reconfiguration, the terminal device maintains at least a portion of the conditional reconfiguration for use in the subsequent conditional cell change. In this way, a procedure of a subsequent conditional cell change may be enabled.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A first device receives, from a second device, information on modification of system information and determines modified system information to be transmitted to a third device based on a stored request for system information from the third device and the information on modification of system information. Then the first device transmits the modified system information to the third device. In this way, delivery of modified SI for remote UE can be achieved with saved power consumption and signaling overhead.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communications. A method implemented at a terminal device comprises in response to switching to a second frequency part, determining a time duration for the terminal device to use a first reference signal received from a network device in a first frequency part as a Quasi Co-location (QCL) reference signal. The terminal device performs communication with the network device before the time duration ends based on a first set of properties obtained by measuring at least the first reference signal. The method also comprises obtaining, within the time duration, a second set of properties by measuring at least a second reference signal received from the network device in the second frequency part, the second reference signal and the first reference signal having a first identification. The method also comprises performing, after the time duration, communication in the second frequency part with the network device based on the second set of properties by using the second reference signal as the QCL reference signal.

Abstract: According to embodiments of the present disclosure, solutions on the transport block over multiple slots (TBoMS) are proposed. A terminal device receives a configuration from a network device. The configuration indicates that a transport block is transmitted over a first number of slots. The terminal device determines a start bit point of a circular buffer in a slot within the first number of slots based on a redundancy version start indication, an index of the slot and a predetermined factor. In this way, two parts of the CSI can be decoded independently and it can achieve improved performances.

Abstract: Example embodiments of the present disclosure relate to small data transmission. Although the present disclosure, the stored data is not taken into consideration when calculating data volume for small data transmission, and thus correct data volume value can be obtained thereby. Further, the terminal device may obtain information about volume of new data before calculating data volume for small data transmission. In addition, during small data transmission, the reported buffer status report may indicate an actual state of the remaining small data transmission data. Further, when the terminal device fails to transmit small data transmission data via 4-step random access procedure, the terminal device may fall back to 4-step random access small data transmission properly.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A terminal device receives an indication of at least one transmission configuration indicator (TCI) state in a detected downlink control information (DCI) in a first physical downlink control channel (PDCCH). The terminal device also receives a downlink transmission from the network device based on the at least one TCI state based on a first condition. The terminal device further applies the at least one TCI state to at least one reference signal (RS) in a first RS set based on the first condition, wherein the first RS set is applied for beam failure detection. Moreover, the terminal device determines an estimation of a radio link quality between the terminal device and the network device based on the first RS set. In this way, proper beam failure detection can be processed.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for Reference Signal (RS) transmission. A method for communication comprises determining one or more RS ports for RS transmission, the one or more RS ports being included in one or more RS groups. The method further comprises determining a plurality of parameters for generating a RS sequence specific to a RS group in the one or more RS groups, the RS group including at least one of the one or more RS ports. The method further comprises generating the RS sequence based on the plurality of parameters. In addition, the method further comprises transmitting the generated RS sequence over the at least one of the one or more RS ports. The embodiments of the present disclosure can solve the PAPR issue caused by mapping a same RS sequence to antenna ports across RS port groups.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. According to embodiments of the present disclosure, a terminal device receives, from a network device, a radio resource control (RRC) configuration comprising a repetition number for physical uplink shared channel (PUSCH) transmission occasions associated with a first sounding reference signal (SRS) resource indicator (SRI) and PUSCH transmission occasions associated with a second SRI, the RRC configuration further comprising a redundancy version (RV) offset to a RV sequence associated with the first SRI. The terminal device receives DCI indicating an identity of a RV. If a first RV sequence determined based on the repetition number, the identity and the RV offset meets a condition, the terminal device does not apply the first RV sequence. In this way, it improves reliability.

Abstract: Embodiments of the present disclosure provide a solution for supporting a successful handover report. In a method for communication, a terminal device receives a report configuration from a first network device providing a first cell. The report configuration indicates whether a successful handover report is to be generated for a handover of the terminal device from the first cell to a second cell of a second network device. Then, the terminal device applies the report configuration during performing of the handover. Through the embodiments of the present disclosure, the terminal device may be limited to reporting a successful handover report if the source network device considers the successful handover report as necessary, thereby saving the processing resources and communication resources for the potentially unnecessary successful handover reports.
