Abstract: Systems, methods, and devices for broadcast service negotiation and non-simultaneous transmit-receive (STR) channel blindness recovery are provided herein. Some methods performed by a Wireless Transmit/Receive Unit (WTRU), may comprise operating over a first link; operating over a second link; receiving a frame including a Network Allocation Vector (NAV) setting associated with the second link, the NAV setting indicating a time duration; and sending a transmission over the first link, wherein a duration of the transmission over the first link is shorter than or equal to the time duration indicated by the NAV setting. The frame including the NAV setting indicates that the time duration may not be extended or modified. The method may further comprise sending, by the WTRU, an indication that it the WTRU is capable of performing a multi-link restricted transmission. The WTRU may enter a sleep mode on the first link after sending the transmission over the first link.

Abstract: Embodiments of the present application provide a method and an apparatus for CSI feedback, an electronic device, and a storage medium. The method for CSI feedback includes: determining a CSI measurement resource corresponding to each data layer group during CSI measurement; determining first correspondence relations between each data layer group and DMRS ports during CSI measurement; determining mapping modes between each data layer group and CSI-RS ports during CSI measurement; determining transmission mode used in CSI measurement and CSI reporting mode corresponding to the transmission mode; and performing CSI feedback according to the CSI measurement resource, the first correspondence relations, the mapping modes, the transmission mode used in the CSI measurement and the CSI reporting mode corresponding to the transmission mode. Therefore, the embodiments of the present application improve flexibility and accuracy of CSI feedback and reduce complexity of CSI feedback.

Abstract: A wireless transmission scheduling method is proposed. The method may be a synchronous media access control (MAC) wireless transmission scheduling method optimized for a user datagram protocol (UDP) of a personal wireless network-based data transmission system. The method may include setting a superframe period, a beacon period, and a contention period by a master station in a network. The method may also include calculating transmission periods of one or more slave stations participating in the network and a transmission period of the master station. The method may further include transmitting information about the calculated transmission periods of the one or more slave stations to the one or more slave stations participating in the network. The method may further include transmitting data by the one or more slave stations and the master station in the transmission periods assigned to the one or more slave stations and the master station.
