Problems solved by technology

However, due to the limitation of the preamble sequence and the diversity of SI types and combinations that the UE expects to obtain, there is a problem of how to obtain multiple SIs when the UE initiates an SI request.

example 11

[0095] Example 1.1: Assuming that the UE receives the following exemplary direct correspondence between the preamble sequence and the SIB:

[0096] The first preamble corresponds to the first SIB, that is, the UE can request the network side to broadcast or unicast the first SIB by sending the first preamble, and the network side / base station can broadcast or unicast to the UE after receiving the first preamble the first SIB;

[0097] The second preamble corresponds to the first SIB and the second SIB, that is, by sending the second preamble, the UE can request the network side / base station to broadcast or unicast the first SIB, and after the network side / base station receives the second preamble, The first SIB and the second SIB may be broadcast or unicast to UEs.

[0098] Based on the above assumptions, when the SIBs that the UE needs to obtain are the first SIB and the second SIB, because the first preamble corresponds to only one SIB required by the UE, and the second pre...

[0099] Example 1.2: Assuming that the UE receives the following exemplary indirect correspondence between the preamble sequence and the SIB:

[0100] The first preamble sequence corresponds to the first SI, that is, the UE can request the network side / base station to broadcast or unicast the first SI by sending the first preamble sequence, and the network side / base station can broadcast or unicast the first SI to the UE after receiving the first preamble sequence Unicast the first SI;

[0101] The second preamble corresponds to the first SI and the second SI, that is, by sending the second preamble, the UE can request the network side / base station to broadcast or unicast the first SI, and after the network side / base station receives the second preamble, The first SI and the second SI may be broadcast or unicast to the UE;

[0102] The first SIB is included in the first SI, and the second SIB is included in the second SI.

Abstract

The disclosure provides a method executed at UE (User Equipment), which comprises the steps of: receiving information from a base station, which carries a direct or indirect corresponding relationshipbetween a leader sequence and a SIB (System Information Block); on the basis of one or more required SIBs and the received corresponding relationship, selecting the corresponding leader sequences according to at least one of the following criterions of: selecting one single leader sequence corresponding to the greatest number of required SIBs, selecting one single leader sequence corresponding the smallest number of unneeded SIBs, selecting one or more leader sequences of which the total number is the smallest and which correspond to the one or more required SIBs, and according to prioritiesof the one or more required SIBs, selecting different leader sequences respectively corresponding to different priorities of required SIBs; and sending the selected leader sequences to the base station so as to request one or more required SIBs for the base station. The disclosure further provides corresponding UE and a computer readable medium.

Description

technical field [0001] The present disclosure relates to the technical field of wireless communication, and more specifically, the present disclosure relates to a system information request method, a corresponding user equipment, and a computer-readable medium. Background technique [0002] With the rapid growth of mobile communication and the great advancement of technology, the world will move towards a fully interconnected network society, that is, anyone or anything can obtain information and share data at any time and anywhere. It is estimated that by 2020, the number of connected devices will reach 50 billion, of which only about 10 billion may be mobile phones and tablet computers, and the rest are not machines that talk to people, but machines that talk to each other. Therefore, how to design a system to better support the Internet of Everything is a topic that requires in-depth research. [0003] To this end, at the 3rd Generation Partnership Project (3GPP) RAN#64 ...
