example 1

[0153] In this example, on the base station side:

[0154] The beams that send the channel occupation request signal are all or some of the beams whose channels are detected as idle after the base station performs the LBT operation in a chronological order in the direction corresponding to at least one beam.

[0155] The beams performing the LBT operation are all possible beams in the space, and / or, a predetermined configuration of possible beams in the network.

[0156] The channel occupancy request signal contains one or a combination of the following information:

[0157]Information about the scheduled UEID, the Beam ID of the beam that sends the channel occupancy request signal, the location information of the beam that sends the channel occupancy request signal in space, and the channel occupancy time information of the beam that sends the channel occupancy request signal , the resource configuration required when the terminal feeds back the signal allowing the channel t...

example 2

[0177] In this example, in implementation, when the base station receives the signal allowing the channel to be occupied on multiple beams, the base station schedules the channel occupation request signal to perform data transmission with the user whose handshake is successful with the signal allowing the channel to be occupied; and / or,

[0178] When the base station receives the signal allowing the channel to be occupied on multiple beams, the base station performs the operation on the beam whose ratio between the number of users sending the signal allowing the channel to be occupied and the number of users receiving the channel occupying request signal is greater than the preset value data transmission.

[0179] In the implementation, on the beam whose ratio between the number of users sending the signal allowing the channel to be occupied and the number of users receiving the channel occupation request signal is greater than the preset value, select the beam that is dominant...

example 3

[0183] For example, in Example 1, it will have a better effect under the condition that the consistency of the sending and receiving beams of the device is guaranteed. However, if the receiving beam and the sending beam of the LBT are not calibrated, they cannot be kept the same In the case of beams, it is not very meaningful to execute LBT in the direction corresponding to the sending beam at this time. The behavior of the base station can be to not execute LBT in the direction corresponding to each beam, but directly in the direction corresponding to the allowed beam At this time, other behaviors of the terminal and the base station may be consistent with Example 1.

Abstract

The invention discloses a request signal sending method and device, a request signal receiving method and device, and equipment,. The request signal sending method comprises the steps that a base station determines a channel occupation request signal needing to be sent, wherein the channel occupation request signal is a request signal for requesting a terminal to carry out the channel occupation after the base station carries out the monitoring operation before a conversation in a direction corresponding to at least one wave beam; and the base station schedules the sending of the channel occupation request signal on a downlink control channel; a terminal detects a downlink control channel sent by the scheduling channel occupation request signal; and the terminal receives the channel occupation request signal according to the detection result. By adopting the invention, the defect that the prior art is not designed for the channel occupation request signal is overcome, and the transmission of the eNB channel occupation request signal is realized. Furthermore, a scheme capable of achieving the lowest power consumption is also provided in the scheme.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, equipment and device for sending and receiving request signals. Background technique [0002] There is no specific application system planned for the unlicensed spectrum, and it can be shared by various wireless communication systems. At present, the existing communication systems in the unlicensed spectrum mainly include IEEE-standardized Bluetooth, WiFi and 3GPP-standardized LTE-U (LTE in unlicensed spectrum, LTE in the unlicensed frequency band; LTE: Long Term Evolution, long-term evolution) system, multiple systems use shared unlicensed spectrum resources by preempting resources. [0003] In order to ensure the friendly coexistence of LTE-U with WIFI, 3GPP conducted in-depth discussions on LBT (listen before talk) technology and provided four LBT solutions. [0004] Cat.1: No LBT (no LBT); [0005] Cat.2: LBT without random back-off (LBT wit...
