Abstract: Embodiments of the present disclosure relate to methods, devices, apparatuses and computer readable storage media for Uplink Control Information (UCI) design. The method comprises determining, at a terminal device, a matrix comprising a set of non-zero linear combination coefficients for quantizing a channel between the terminal device and a network device, the matrix having spatial components and frequency components; shifting the frequency components of the matrix circularly, such that a target coefficient of the set of non-zero linear combination coefficients is located in a frequency component with a predetermined index of the frequency components in a shifted matrix; generating a first indication indicating the spatial component associated with the target coefficient in the matrix; and transmitting, to the network device, uplink control information comprising the first indication. In this way, a new solution for designing the UCI may reduce the overhead for reporting the parameters in the UCI.

Abstract: Example embodiments of the present disclosure relate to methods, devices apparatuses and computer readable storage media of an access procedure for Cell-free Multi-input Multi-output (MIMO). In example embodiments, a terminal device transmits an access request to a first set of uplink access network devices. The access request contains a list of identifications of candidate downlink access network devices. Then, the terminal device receives an access response from a first set of downlink access network devices.

Abstract: Methods and apparatuses for multi-channel communications are disclosed. A method provides precoding, based on sounding reference signal received from a communication device, reference signal ports in spatial and frequency domain by determining pairs of spatial and frequency domain components where the frequency domain components are arranged in clusters comprising one or more frequency domain components, and pairing of at least one of the spatial domain components with at least two clusters of frequency domain components is enabled; sending information of the precoding to the other communication device; and combining the precoding with a report of precoding received in response from the other communication device. Another method provides sending of the sounding reference signal; receiving, the information of the precoding; performing port selection operation based on the clustered information of frequency domain components; and preparing and sending the report based on the selection operation.
