Abstract: A transmission method, a transmission apparatus, a network device, and user equipment are provided, and are applied to the field of communications technologies. The method includes: configuring, by a base station, a resource request parameter for first UE; allocating a first PUSCH resource used by the first UE to send resource request information; and allocating, to the first UE when the base station detects, on the first PUSCH resource, resource request information sent by the first UE, a second PUSCH resource used for sending data. In this way, PUCCH capacity limitation is effectively mitigated, and more UEs can send resource requests, so that resource usage in an uplink transmission process can be increased, and a system capacity can be increased.

Abstract: Embodiments provide a communication method, terminal, and a base station. The method includes: receiving, by terminal, a reference signal sent by a base station; and obtaining, by the terminal, channel energy of a narrow beam by measuring the reference signal, where the narrow beam is a directional beam. According to the communication method in the embodiments of the present disclosure, the terminal may obtain the channel energy of the narrow beam by measuring the reference signal. Compared with the prior art in which channel energy of a narrow beam is measured on a base station side, a difference is that the terminal can more accurately estimate the channel energy of the narrow beam. That is, the channel energy of the narrow beam estimated by the terminal can more accurately reflect channel quality, and transmission efficiency can be improved.

Abstract: Embodiments of this disclosure provide a communication method and a related device. In certain embodiments, the method includes determining, by a network device, a first resource set, the resources included in the first resource set are periodic. At a same transmission moment, the first resource set serves only one terminal device or one terminal device group, the terminal device group including a plurality of terminal devices. At different transmission moments, resources used for co-directional transmission in the first resource set occupy a same frequency domain position on a same carrier. The method includes sending, by the network device, resource configuration information to the terminal device by using higher layer signaling. The resource configuration information is used to indicate the first resource set.
