Abstract: Embodiments of the present disclosure relate to a method, device and computer readable storage medium of communication. The method performed by the terminal device comprises initiating an RRC connection release procedure during the terminal device performing a SDT with a network device. The method further comprises disabling indicating an arriving of non-small data transmission to the network device during the RRC connection release procedure. In this way, the RRC connection release procedure may be completed without any disturbing, and the state between the terminal device and the network device may be consistent.

Abstract: Embodiments of the present disclosure relate to methods for communication, terminal devices, network devices and computer readable media. In the method, a terminal device determines a transmission configuration indicator (TCI) state for a physical downlink control channel (PDCCH) candidate, based on at least one of: an index of the PDCCH candidate, and an index of a control channel element (CCE) of the PDCCH candidate. The terminal device monitors the PDCCH candidate based on the TCI state. As a result, the complexity of the terminal device for blind detection or decoding is able to be reduced.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. According to embodiments of the present disclosure, the terminal device performs a cyclic shift on a sequence of uplink control information. The terminal device further performs an orthogonal spread on the sequence with the cyclic shift. The terminal device transmits the processed sequence to the network device. In this way, it avoids wasting transmission resources for DMRS. Further, it also avoids too complicated sequence detections.

Abstract: Example embodiments of the present disclosure relate to communication. According to embodiments of the present disclosure, a network device transmits configuration information for one or more frequency hopping modes to a terminal device. The terminal device determines which frequency hopping mode is used and also determines a plurality of frequency hopping positions based on the configuration information. In this way, it can have more frequency hopping positions which achieve more frequency diversity gain and benefit to coverage enhancement. Further, the frequency hopping frequency is configured more flexible.

Abstract: Embodiments of the present disclosure relate to methods, devices and apparatus of resource mapping for data transmission and of data receiving. In an embodiment of the present disclosure, a carrier frequency band for the data transmission is divided into a plurality of sub-bandwidths, and the method may include mapping resource elements for the data transmission in an order of sub-bandwidths and mapping, in each of the plurality sub-bandwidths, the resource elements first in an order of frequency domain and then in an order of time domain. With embodiments of the present disclosure, new radio access system with wider bandwidth could co-exist well with other communication on unlicensed band like WiFi.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media of communication. A method of communication implemented by a terminal device comprises generating, in an inactive state, a first control element of a media access control layer, the first control element carrying a first identity of the terminal device; and transmitting, to a network device, the first control element and uplink data. The method of communication implemented by a network device comprises receiving the first control element and uplink data from the terminal device; and transmitting the uplink data to a core network element. In this way, small data transmission can be achieved in an inactive state of the terminal device with reduced signaling overhead.

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: 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.
