  • Patent number: 11968659
    Abstract: The present disclosure provides a method of scheduling for a UE. The method includes dividing M UEs into N groups, wherein a distance metric between each UE in a group and the center of the group does not exceed a first predetermined threshold, where M and N are positive integers; pairing the N groups, wherein a distance metric between centers of the two paired groups is greater than a second predetermined threshold; and in a case where there is a group paired with a group to which a first UE for which scheduling is to be performed belongs, scheduling transmissions in different directions respectively for the first UE and the second UE from the paired group on the same time-frequency resource. The present disclosure also provides a signal transmission method, a base station, a UE and a computer readable medium.

  • Patent number: 11963192
    Abstract: The present invention discloses a method for receiving scheduling information, comprising steps of: receiving Downlink Control Information (DCI); and determining, according to a mapping relationship between configured transmission resources used for a Physical Uplink Shared Channel (PUSCH) and scheduling information in the DCI, scheduling information corresponding to the PUSCH in the DCI. Compared with the prior art, in the present invention, the scheduling information in the DCI is determined by the mapping relationship between the configured transmission resources used for transmitting the PUSCH by a UE and the scheduling information in the DCI, so that a base station can schedule all UEs for which there is a mapping relationship between PUSCH configured transmission resources and the scheduling information in DCI by sending only one piece of DCI. The scheduling overhead is reduced, the resource waste is reduced, and the efficiency of scheduling terminals by a communication system is significantly improved.

  • Publication number: 20240080153
    Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments of the present application provide a method performed by a network controlled repeater (NCR) in a wireless communication system. The method includes receiving, by an NCR mobile terminal (NCR-MT) from a base station, control information; identifying a forwarding state of an NCR-amplifier and a resource corresponding to the forwarding state based on the control information: receiving, by the NCR-MT from the base station, a downlink signal; and forwarding, by the NCR-amplifier to a user equipment (UE), the downlink signal on the identified resource, in case that the forwarding state is a forwarding-on state.
