20/55 bottom link sent by at least part of the transmission beams coinciding with the receiving beam in the measurement report.
[093] In at least one embodiment, the same antenna panel can correspond to several reception beams or receive groups of beams with the first reception capacity.
[094] In at least one embodiment, a receiving beam or group of receiving beams with the second receiving capacity may correspond to at least one antenna panel. Antenna panels corresponding to several reception beams or groups of reception beams with the second reception capacity are not overlapped.
[095] For the convenience of understanding the first receiving beam and the second receiving capacity, detailed descriptions will be made below in combination with Fig. 3 and Fig. 4.
[096] As shown in Fig. 3, the network device can send lower link signals to the terminal device via a transmission beam Bl, transmission beam B2 and transmission beam B3 from an emitting node 1 and can send lower link signals to the terminal device via a transmission beam B4, transmission beam B5 and transmission beam B6 from an emitting node 2. The terminal device can receive the lower link signals sent by the network device via two receiving beams, that is, a receiving beam bl and a receiving beam b2.
[097] The network device can send lower link measurement signals to the terminal device via
Petition 870190090451, of 12/09/2019, p. 26/160

[098] The measurement result can, for example, be illustrated as follows. Consider that the measurement result is the Received Reference Signal Power (RSRP) and beam pairs that are not related can be considered
with power in signal particularly low and can be ignored.[Bl bl] -60dB [Bl b2] -120dB [B2 bl] -70dB [B2 b2] -120dB [B3 bl] -lOOdB [B3 b2] -120dB [B4 bl] -120dB [B4 b2] -lOOdB [B5 bl] -120dB [B5 b2] -65dB [B6 bl] -120dB [B6 b2] -7 5dB [099] Case must to be Four bundles of

[0100] The beam pairs [Bl bl], [B2 bl], [B5 b2] and [B6 b2] correspond to the ideal signal quality and then the four pairs of beams can be reported.

can be illustrated as follows. [Bl bl] -60dB [B2 bl] -70dB [B5 b2] -65dB [B6 b2] -7 5dB [0101] When the network device receives the
measurement result, it can be learned that the same receiving beam can simultaneously receive signals sent by different transmission beams. This means that the network device can simultaneously send the lower link signals to the terminal device using Bl and B2 or B5 and B6.
[0102] As shown in Fig. 4, the network device can send lower link signals to the terminal device via transmission beam Bl, transmission beam B2 and transmission beam B3 from the emitting node 1 and can send signals from lower link to the terminal device by means of the transmission beam B4, transmission beam B5 and transmission beam B6 of the emitting node 2.

The receiving beam group bl can include receiving beams bl-1 and bl-2 and the receiving beam group b2 can include receiving beams b2-l and b2-2.
[0103] The network device can send lower link measurement signals to the terminal device via transmission beam Bl, transmission beam B2, transmission beam B3, transmission beam B4, transmission beam B5 and transmission beam B6. The terminal device can measure the lower link signals sent by
Petition 870190090451, of 12/09/2019, p. 28/160
23/55 each transmission beam using the receiving beams bl1, bl-2, b2-l and b2-2 to obtain a measurement result. The terminal device can select a transmission beam according to the measurement result.
[0104] The measurement report can, for example, be illustrated as follows. Consider that the measurement result is RSRP and unrelated beam pairs can be considered to be of particularly low signal strength and can be ignored.
[Bl bl-1] -60dB [Bl bl-2] -120dB [B2 bl-1] -70dB [B2 bl-2] -120dB [B3 bl-1] -lOOdB [B3 bl-2] -120dB [B4 b2-l] -120dB [B4 b2-2] -lOOdB [B5 b2-l] -120dB [B5 b2-2] -65dB [B6 b2-l] -120dB [B6 b2-2] -7 5dB
[0105] If four transmission beams are to be reported, several pairs of beams can be selected from the result and the selected beam pairs and the corresponding measurement result can be reported.
[0106] The beam pairs [BI bl-1], [B2 bl-1], [B5 b2-2] and [B6 b2-2] correspond to the ideal signal quality and then the four pairs of beams can be reported. In the reporting process, a receiving beam group identifier corresponding to each receiving beam can be reported.
