Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication of a RS. A method of communication comprises determining, at a network device, information indicating a first number of resources configured for communication of a RS, the first number being associated with a third number of transmit antenna ports and a fourth number of receive antenna ports of a terminal device and the fourth number being larger than a predetermined number; and transmitting the information to the terminal device. The method further comprises receiving, at the terminal device, the information; determining a second number of resources from the first number of resources, the first number being larger than or equal to the second number; and performing the communication of the RS based on the second number of resources. Embodiments of the present disclosure can achieve a RS resource configuration and a RS communication for increased antenna ports.

Abstract: Embodiments of the present disclosure relate to a method, network device, and apparatus for transmitting a preemption indication and a method, terminal device, and apparatus for receiving a preemption indication. In an embodiment of the present disclosure, the method of transmitting a preemption indication may comprise transmitting a preemption indication to a terminal device, wherein the preemption indication indicates information on a portion of resources allocated to a first transmission which is preempted by a second transmission, and wherein the preemption indication is associated with information on structure of the current slot. In embodiments of the present disclosure, by means of information on structure of a subframe, the indication monitoring and overhead for the preemption indication can be reduced remarkably, thereby providing a much more efficient preemption indication solution.

Abstract: Embodiments of the present disclosure provide a solution for improving feedback information for transmissions with repetition in a communication system. In a method for communication, a terminal device can obtain a first group of candidate offsets for transmissions of a first type and a second group of candidate offsets for transmissions of a second type. The terminal device may receive, from the network device, scheduling information for scheduling a transmission in a first slot, the scheduling information comprising a target offset selected from the first group of candidate offsets, the target offset indicating a second slot associated with a feedback indication for the transmission. The terminal device may determine a set of slots based on the second slot and the first group of candidate offsets. The terminal device may transmit, to the network device in the second slot, a set of feedback indications for the set of slots. Embodiments of the present disclosure can optimize and improve the reporting of feedback information by the terminal device to the network device in the communication system.

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 transmitting UL 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.
