Description
Technical field
The present invention relates to the transmission plan in wireless communication system, more particularly to the method and apparatus of random access.
Background technology
The increasingly diversification of the application scenarios of future broadband wireless communication systems, different application scenarios propose difference to system
Performance requirement.In order to meet the different performance requirements of plurality of application scenes, in 3GPP (3rd Generation Partner
Project, third generation cooperative partner program) in RAN (Radio Access Network, wireless access network) #72 plenary session certainly
It is fixed that new technology (NR, New Radio) of eating dishes without rice or wine is studied.
(Massive) MIMO becomes a research hotspot of next generation mobile communication system NR on a large scale.Extensive MIMO
In, mutiple antennas forms one certain party of relatively narrow beam position and always improves communication quality by beam shaping.Multiple antennas ripple
The wave beam that beam excipient is formed is generally narrow, and the partial channel knowledge that communicating pair needs to obtain other side can just make the wave beam to be formed
Direction is correctly oriented.Before the partial channel knowledge that communicating pair obtains other side, or the local channel letter obtained before
In the case that breath has failed, transmitting terminal and receiving terminal need to connect to ensure to send the correct of signal using the redundancy of bigger
Receive, for example wave beam mops up (Beam Sweeping) scheme, i.e. transmitting terminal passes through TDM (Timing Division
Multiplexing, is time-multiplexed) mode repeatedly send same signal, every time send for different directions wave beam, together
When receiving terminal using it is no reception wave beam repeat signal in select suitable signal.Initiated in user equipment initial random
During access (such as random access based on collision), when not having mutual benefit between the wave beam of uplink and downlink
(Reciprocity), i.e., it can not judge to send wave beam by receiving wave beam, or judge to receive wave beam by sending wave beam
When, user equipment and base station equipment are required for being mopped up using wave beam and ensure being properly received for random access channel.
The content of the invention
During initial random access, two (or multiple) different user equipment (UE) using competition by the way of to
Random access request is initiated in base station, and identical targeting sequencing (Preamble) is have selected simultaneously if there is at least two user equipmenies
And during the transmission to Preamble is mopped up using wave beam, when base station is possible to receive from two or more differences
The identical Preamble carved, this, which will result in base station, can not judge that these identical Preamble are set from same user
Standby or different user equipment, so that cause the subsequent step in random access to include random access response (Msg2),
There is deviation or fuzzy in the information that Msg3 and Conflict solving (Msg4) carry.Especially when base station is received on different Beam
Multiple identical Preamble when, send the user equipment of these Preamble since spatial reuse will not collide, from
And can be successfully accessed, but existing Random Access is based on, such as LTE (Long Term Evolution, term
Evolution) in Random Access, sent in identical running time-frequency resource in the user equipment of identical Preamble only have one
It is a to be finally successfully accessed.If continuing to use the Random Access of existing (such as LTE), fuzzy cause base station due to above-mentioned
Make the collision to make mistake to solve to determine, or cause the increase of waste and the random access delay of resource.
The problem of fuzzy and wasting of resources is collided caused by for being mopped up due to random access procedure using wave beam, the present invention
Provide solution.Solution using the present invention, by supporting Msg2, Msg3 or Msg4 in random access procedure
Multi-beam send, while the beam information of each step is associated solve mopped up due to wave beam caused by obscure, and
Support the random access multiplexing in space, improve the performance of random access.It should be noted that in the case where there is no conflict, this Shen
The feature in the embodiment and embodiment in UE (User Equipment, user equipment) please can be applied in base station, instead
