Abstract: Embodiments of the present disclosure relate to devices, methods, devices and computer readable storage media of resource allocation for coverage enhancement. The method comprises receiving, at a terminal device and from a network device, an indication of a resource allocation mode to perform an uplink data transmission, the resource allocation mode at least indicating resources allocated for the uplink data transmission being to be mapped on a plurality of slots, the plurality of slots comprising no symbols configured for downlink transmission; and transmitting the uplink data transmission based on the indication. In this way, the capability of coverage enhancement for the User Equipments (UEs) can be improved by scheduling the resources for the Physical Uplink Shared Channel (PUSCH) according to the approach of resource allocation of the present disclosure.

Abstract: Embodiments of the present disclosure provide a solution for scaling time for performing uplink and downlink transmissions. In a method for communications, a network device obtains a capability indicator of a terminal device. The network device determines a target scheduling scheme for the terminal device based on the capability indicator. The network device transmits information associated with the target scheduling scheme to the terminal device. The information associated with the target scheduling scheme causes the terminal device to perform uplink and downlink transmissions based on the target scheduling scheme. Embodiments of the present disclosure provides a more flexible and adaptive configuration and scheduling manner, and thereby improving communication performances and reducing the cost of terminal devices.

Abstract: Embodiments of the present disclosure relate to communication. According to embodiments of the present disclosure, if an expiration of a data inactivity timer occurs during a handover, a terminal device maintains in a RRC connected state. The terminal device releases a link with the source network device. Further, the terminal device is able to ignore the expiration of the data inactivity timer during the handover. In this way, the impact of data inactivity of the source network device is properly handled.

Abstract: Embodiments of the present disclosure provide a solution for coverage enhancement. In a method for communication, a terminal device receives, from a network device, information on an inferring relation between a first channel associated with a first slot and a second channel associated with a second slot. The terminal device determines, based on the information, whether the first and second channels are to be inferable from each other. In accordance with a determination that the first and second channels are to be inferable from each other, the terminal device performs communications with the network device on the first and second channels based on the inferring relation. Embodiments of the present disclosure effectively enhance coverage of communications, thereby improving communication performance.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A method of communication comprises determining, at a terminal device, whether first paging occasion information of a first paging overlaps with second paging occasion information of a second paging; and in response to the first paging occasion information overlapping with the second paging occasion information, transmitting an indication of paging collision between the first paging and the second paging to a network device associated with the first paging. In this way, the solving of the paging collision issue can be facilitated at RAN side, and low latency and high efficiency can be achieved.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for data transmission during simultaneous connectivity based handover. A method of communication comprises in response to a second connection being established between a second network device and a terminal device having a first connection with a first network device, determining, at the first network device, a first set of SDUs to be transmitted by the second network device to the terminal device; determining first information regarding a SN assigned to each of the first set of SDUs and a HFN associated with the SN; and transmitting the first set of SDUs and the first information to the second network device. The method further comprises receiving, at the second network device, the first set of SDUs and first information; and transmitting the first set of SDUs to the terminal device based on the first information. The method further comprises receiving, at the terminal device, a first set of PDUs corresponding to the first set of SDUs from the second network device; receiving a second set of PDUs corresponding to the second set of SDUs from the first network device; determining the first information; and determining an order of the first and second sets of PDUs based on the first information. Embodiments of the present disclosure can facilitate correct data transmission during a simultaneous connectivity based handover and improve data transmission efficiency.
