Fig. 2 is referred to, is a kind of flow diagram of communication means provided by the embodiments of the present application, this method is set from terminal The standby angle interacted with the network equipment is introduced, and this method can include but is not limited to:
Step S201: the network equipment, which is determined, triggers aperiodic wave beam scanning for terminal device；
In a kind of mode in the cards, the network equipment determines whether needle according to current beam scanning attribute information Aperiodic wave beam scanning is triggered to terminal device.
Wherein, beam scanning attribute information can include but is not limited to beam angle, beam scanning density, beam scanning side To, beam scanning range etc..Beam angle can be broad beam or narrow beam.Beam scanning density can be oversample factor (oversampling factor).Beam scanning direction can be horizontally oriented, vertical direction or horizontal+vertical direction.Wave beam Scanning range refers to beam-scanning angles range.
Current beam scanning attribute information refers to the beam scanning attribute information in P-1 stage, can be the stage net The beam scanning attribute information of network equipment side is also possible to the beam scanning attribute information of the stage terminal equipment side, the application Embodiment does not limit this.
It is pre- that the network equipment can determine whether current beam scanning attribute information meets first by following several situations If trigger condition, and then determine whether to trigger aperiodic wave beam scanning for terminal device.
The beam angle in one: P-1 stage of situation is broad beam, and beam angle needed for aperiodic wave beam scanning is narrow beam, I.e. one of first preset trigger condition is narrow beam, then it is pre- to determine that current beam scanning attribute information is unsatisfactory for first If trigger condition；
The beam scanning range in two: P-1 stage of situation is smaller, and the beam scanning range of aperiodic wave beam scanning is larger, i.e., The two of first preset trigger condition are to preset more than or equal to default beam scanning range if current beam scanning range is less than When beam scanning range, it can determine that current beam scanning attribute information is unsatisfactory for the first preset trigger condition；
The beam scanning density in three: P-1 stage of situation is larger, and the beam scanning density of aperiodic wave beam scanning is larger, i.e., The three of first preset trigger condition are to preset more than or equal to default beam scanning density if current beam scanning density is less than Beam scanning density can determine that current beam scanning attribute information is unsatisfactory for the first preset trigger condition；
The beam scanning direction in four: P-1 stage of situation is horizontal direction or vertical direction, and aperiodic wave beam scanning needs to increase Add vertically or horizontally, i.e., the four of the first preset trigger condition are two beam scanning directions, then needing to increase In the case where beam scanning direction, it can determine that current beam scanning attribute information is unsatisfactory for the first preset trigger condition；
It should be noted that above-mentioned four kinds of situations, which are not constituted, is unsatisfactory for first in advance to current beam scanning attribute information If the restriction of trigger condition, can also be worked as in practical application by the combination of at least two situations in above-mentioned four kinds of situations to determine Whether preceding beam scanning attribute information meets the first preset trigger condition, can also determine current wave by other means Whether beam scanning attribute information meets the first preset trigger condition.
In the case where current beam scanning attribute information is unsatisfactory for the first preset trigger condition, the network equipment can be true Surely it needs to trigger aperiodic wave beam scanning for terminal device.Aperiodic wave beam scanning can correspond to P-2 stage, P-3 stage Or the combination in P-2 stage and P-3 stage.P-2 stage and P-3 stage can be independent scanning, can also be with Combisweep.For non- Period beam scanning, especially for the P-3 stage, the network equipment needs to configure the corresponding aperiodic wave beam scanning letter of terminal device Breath, including reference signal resource configuration information and measurement report configuration information etc..
The network equipment can will be in current beam scanning attribute information in the case where that is unsatisfactory for the first preset trigger condition institute The triggering type of the aperiodic wave beam scanning of triggering is determined as the first triggering type.
In the mode of alternatively possible realization, the network equipment reports the information to be to determine according to from terminal device is received It is no to trigger aperiodic wave beam scanning for terminal device.
Wherein, information is reported to can be measurement report, measurement report may include the measurement such as RSRP, RSSI, RSRQ, SINR At least one of parameter.Information is reported to can also be that feedback information, feedback information may include hybrid automatic repeat-request (hybrid auto repeat request, HARQ) statistical information etc., when there are data between terminal device and the network equipment When transmission, terminal device can send feedback information to the network equipment.
The network equipment can be determined by following two situation reports whether information meets the second preset trigger condition, in turn Determine whether to trigger aperiodic wave beam scanning for terminal device.
Situation one: whether it is lower than measurement ginseng from one or more measurement parameters in the received measurement report of terminal device Several or these measurement parameters preset thresholds report information to meet the second preset trigger condition if so, can determine, i.e., and at this time the One of two preset trigger conditions are the preset threshold less than measurement parameter.The preset threshold of some measurement parameter can be different Correspond to different values under scene, the specific value of preset threshold is in the embodiment of the present application without limitation.
Situation two: by taking HARQ statistical information as an example, whether it is greater than or equal to from the received HARQ statistical information of terminal device Default HARQ statistical magnitude reports information to meet the second preset trigger condition if so, can determine, i.e. the second default triggering at this time The two of condition are more than or equal to default HARQ statistical magnitude.The specific value of default HARQ statistical magnitude is in the embodiment of the present application In without limitation.
It should be noted that above-mentioned two situations are not constituted to the limit for reporting information to meet the second preset trigger condition It is fixed, it can also be determined by the combination of above-mentioned two situations in practical application and report whether information meets the second default triggering item Part can also determine by other means and report whether information meets the second preset trigger condition.
In the case where reporting information to meet the second preset trigger condition, the network equipment, which can determine, to be needed to set for terminal Standby triggering aperiodic wave beam scanning, can be determined as second for the triggering type of the aperiodic wave beam scanning triggered in this case Trigger type.
