Abstract: Embodiments of the present disclosure relate to methods and apparatuses for Control State Information (CSI) transmission. In example embodiments, a method implemented in a terminal device is provided. According to the method, in response to receiving DCI from a network device, a configuration for transmitting CSI to the network device is determined at least based on the DCI. The DCI indicates a CSI-RS for determining the CSI and timing information associated with the CSI. The CSI is determined by measuring the CSI-RS in response to receiving the CSI-RS from the network device. The CSI is transmitted to the network device based on the configuration.

Abstract: Embodiments of the present disclosure relate to a method and apparatus of transmitting uplink (UL) information and a method and apparatus of receiving UL information. In one embodiment of the present disclosure, the method of transmittingUL information comprises transmitting a reference signal using a first sequence; and transmitting UL control information using a second sequence; wherein a reference signal and the UL control information are staggered-multiplexed in frequency domain. With embodiments of the present disclosure, the uplink information can be transmitted in reduced uplink symbols so as to adapt for a proposed subframe structure with reduced uplink symbols and thus, the transmission latency can be reduced greatly.

Abstract: A method for performing transmission between a base station and a terminal device according to a frame structure over an unlicensed spectrum in a wireless network that supports communications over a licensed spectrum and the unlicensed spectrum. The frame structure includes a first set of time resources and at least a first number of consecutive downlink subframes. The method includes determining, during the first set of time resources, availability of an unlicensed carrier in the unlicensed spectrum and reserving a subset in the first set of time resources on the unlicensed carrier upon the unlicensed carrier being determined to be available. The method also includes performing downlink transmission from the base station to the terminal device at least partially within the first number of consecutive downlink subframes on at least the unlicensed carrier in response to a duration of the reserved subset of time resources expiring.

Abstract: Embodiments of the present disclosure relate to methods and apparatuses for control resource mapping. In example embodiments, a method implemented in a communication device is provided. According to the method, REG indices for a plurality of REGs are obtained in a control channel region. The REG bundle indices are determined based on the REG indices and a pattern of REG bundle. The pattern of REG bundle indicates the number of REGs in the frequency domain and the number of OFDM symbols in the time domain. CCE indices are determined based on the determined REG bundle indices and the number of CCEs in the control channel region. The CCE indices are continuous with respect to the REG bundle in the frequency domain.

Abstract: Embodiments of the present disclosure relate to methods and devices for reference signal (RS) transmission. In example embodiments, a method implemented in a network device is provided. According to the method, a first set of RS resources are determined for RS transmission by the network device. The first set of RS resources are associated with a first number of RS ports to be used for RS transmission and correspond to a first set of resource elements (REs) interpolated with unused REs in frequency domain. A first RS configuration for RS transmission is generated based on the first set of RS resources. Information on the first RS configuration is transmitted to a terminal device served by the network device.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media of communication. A terminal device receives, from a network device, a first configuration information transmitted on a first cell, wherein the first configuration information includes a set of TCI states, and the set of TCI states is associated with a second cell different from the first cell. The terminal device receives a first activation command to activate one or more TCI states, wherein the one or more TCI states comprise at least one TCI state from the set of TCI states. The terminal device applies the one or more activated TCI states from a first slot after a predefined timing. In this way, a beam for the second cell can be indicated according to the TCI state indicated by the first cell before serving cell change; accordingly, the latency, the overhead and the interruption time during the inter-cell mobility can be reduced.
