The Base Transmitter wave beam answered is different；Such as the quantity for CSI-RS resource needed for UE reception beam scanning；Such as some
CSI-RS resource concentrates the quantity of CSI-RS resource, and the CSI-RS resource concentrates Base Transmitter wave corresponding to CSI-RS resource
Shu Xiangtong；Such as the reference coefficient of CSI report cycle, the reference coefficient corresponding UE in the period receive the quantity or right of wave beam
Answer the number of repetition of CSI-RS resource corresponding to Base Transmitter wave beam.
Beam scanning period type can serve to indicate that periodicity (periodic) beam scanning, semi-persistent (semi-
Persistent) beam scanning or aperiodicity (aperiodic) beam scanning.For example, launching beam numerical value is 4, received wave
Beam quantity is 2, then the network equipment can configure 8 different CSI-RS resource, aperiodic (aperiodic) is can be used in correspondence
Beam scanning, CSI-RS resource different at this time represent different transmitting-receiving wave beams pair；It can also be configured 4 different CSI-RS moneys

It accuses.If the network equipment, which fails to obtain, receives number of beams, report cycle can only be based on a certain secondary taking turn week of launching beam
Phase is reported, that is, terminal device has often swept 4 launching beams, just one-shot measurement is reported to report.In contrast, former side
Formula can save and report expense.
Report parameter may include Reference Signal Received Power (reference signal receiving power,
RSRP), Reference Signal Received Quality (reference signal received quality, RSRQ) or received signal strength
Indicate at least one of parameters such as (received signal strength indication, RSSI).
It further include step S305 and step S306 after step S304 in a kind of embodiment in the cards.

Table 9
| Value (K1=2 bit) | Between reception wave beam amount field |
| 0 | [1,2] |
| 1 | [3,6] |
It is understood that the beam scanning capabilities of different terminal equipment have a certain difference, some terminal devices do not have
There are beam scanning capabilities or beam scanning capabilities weaker, there is a high likelihood that falling into the range of [1,2], some terminal devices
Beam scanning capabilities are stronger, there is a high likelihood that falling into the range of [3,6].
Step S404: the network equipment configures resource allocation information according to the numerical intervals and reports in configuration information at least
It is a kind of.
