Because wave beam is narrower, carries out optimal or suboptimum wave beam the multidiameter delay of wave beam training acquisition and compare Long Term Evolution (LTE, Long Term Evolution) can be reduced substantially.Fig. 1 show the wave beam difference schematic diagram in correlation technique.It is different The beam capabilities of equipment have differences, in order to resist multidiameter delay, if unified configuration may not necessarily reach system optimal.

After Traffic Channel introduces precoding, due to beam gain, transmission covering and the control channel meeting of Traffic Channel Difference is produced, this species diversity equally includes the difference of delay spread.LTE, which, at present embodies this species diversity, and current The control information of the multiple terminals of control channel multiplexing, and the difference of multiple terminal Existential Space positions, if still set according to this Meter, control channel should still use theaomni-directional transmission or wider beam transmission, and Traffic Channel is for each terminal, from From the point of view of link budget and interference, Traffic Channel is transmitted using narrow beam.Therefore, it is necessary to control channel and business are believed Road separately designs the configuration of its cyclic prefix (CP, Cyclic Prefix).

In addition, the intercarrier that LTE is supported is separated with 15kHz and 7.5kHz, and NR systems will support more carrier wave intervals, i.e., Just flexible subcarrier spacing configuration may also be carried out in same frequency range.

NR systems need to support different frequency range, different use-cases.For example, high band is more prone to the transmission mechanism of narrow beam, if The standby side using more cooperation transmissions (CoMP, Coordinated Multiple Points Transmission/Reception) Case is to lift reliability or handling capacity.These situations all cause terminal or base station experienced different communication environments, and its CP's matches somebody with somebody Put demand also difference, and the LTE network of correlation technique is to carry out CP configurations by broadcasting, this mode to different frequency range, The bad adaptability of different use-cases.For example, terminal can undergo different communication environments in moving process, its multidiameter delay can occur Change, its different communication environments of the positions of different terminals are there is also difference, and terminal is in mode handover procedure is carried out (such as from list Point transmission is switched to multicast communication) it will also result in the difference of multidiameter delay.These situations require matching CP configurations.
