Present disclose provides a kind of methods in user equipment (UE), including：The top-quality downlink wave beam of selection signal is as descending reference from multiple downlink wave beams；And uplink is carried out based on the descending reference.
Description
Technical field
This disclosure relates to wireless communication technology field, more specifically, this disclosure relates to user equipment, base station and related side
Method.
Background technology
In March, 2016, in third generation partner program (3rd Generation Partnership Project：
3GPP) in RAN#71 plenary session, NTT DOCOMO propose a new research project about 5G technical standards (referring to non-special
Sharp document：RP-160671：New SID Proposal：Study on New Radio Access Technology), and obtain
Approval.The purpose of the research project is to develop a new wireless (New Radio：NR) access technology is answered with meeting all of 5G
With scene, demand and deployed environment.Mainly there are three application scenarios by NR：Mobile broadband communication (the Enhanced Mobile of enhancing
Broadband：EMBB), large-scale machines class communicates (massive Machine Type Communication：MMTC) and super
Reliable low latency communicates (Ultra Reliable and Low Latency Communications：URLLC).It is ground according to this
Study carefully a goal programming, two stages of standardization point of NR carry out：The standardization effort of first stage will be completed in mid-terms in 2018；
The standardization effort of second stage will be completed in the end of the year 2019.The standard criterion of first stage wants forward compatibility in second stage
Standard criterion, and the standard criterion of second stage will be established on standard criterion in the first stage, and meet 5G NR technical bids
Accurate is required.
It, can be widely using wave beam (beam) come into the transmission of row information in NR.In multi-beam transmission system, no matter
Being uplink or downlink can use multiple wave beams to be serviced for the same user equipment (User Equipment, UE).Make
When with multiple multi-beam transmissions, how to handle uplink transmission timing becomes problem to be solved.

Between calculate the Timing Advance of the uplink beam, and should in random access response (Random Access Response)
Lead informs UE.UE using the Timing Advance on the subsequent upstream transmission of the uplink beam to adjust its uplink when being sent
Between.In subsequent transmission process, base station can make UE renewal time leads by time advance order.
When the switching of the uplink beam of UE (such as since the geographical location movement of UE causes the uplink beam of original configuration to be believed
Number be deteriorated, need replacing new uplink beam), at this time because UE can not judge that source uplink beam and target uplink beam whether may be used
To use identical Timing Advance, so UE can not determine whether to obtain new Timing Advance by random access.
Therefore, in beam switchover, how to obtain Timing Advance also becomes problem to be solved.
