Description
Technical field
Carried out in base station (eNB) the present invention relates to communication technical field, more particularly to one kind
The method and apparatus of row Stochastic accessing.
Background technology
Millimeter wave (millimeter wave) frequency band primary frequency range is 30GHz to 300GHz,
Because of its abundant frequency resource (equivalent to more than 200 times of 4G networks), think most have by industry
Wish to realize the kilomegabit level wireless access in following 5th generation wireless communication technology (5G).
But, frequency higher can cause signal attenuation higher, and this is also that millimetre-wave attenuator will
The maximum technological challenge for facing.Using the wave beam forming having compared with high directivity and can also make
Adjusted with extensive multiple-input and multiple-output (Multi-Input ＆ Multi-Output, MIMO)
The sensing of wave beam, so as to make up the decay of data transfer.It is general in extensive MIMO technology
Use the limited radio-frequency channel (radio frequency) less than antenna number, it is contemplated that performance
Balance between advantage and implementation cost, the implementation cost includes being directly proportional to radio-frequency channel number
Hardware cost and signal transacting computation complexity and energy ezpenditure.
Due to that cannot know optimal transmission or reception beam position, uplink random access procedure is but
Can not be benefited from wave beam forming.Therefore, if the mode of traditional uplink random access procedure
Be applied to millimeter wave frequency band, due to path loss higher, user equipment (UE) probably due to
Receive base station (eNB) signal quality excessively poor and cannot be successfully accessed.

Also, eNB is based respectively on each beam position of itself to receive each wave beam based on UE
Point to the targeting sequencing for sending such that it is able to determine that eNB and UE each send or connect to each other
A pair optimal beam positions of data are received, so that eNB and UE make respectively in subsequent step
Pointed to send or receive data with identified optimal beam.
Then, in step P2, eNB uses institute after the targeting sequencing for detecting UE transmissions
The optimal beam of determination is pointed to and to send accidental access response (Random Access to the UE
Response, RAR) information, leading sequence of the accidental access response information including detected by
Column information, up timing information, and resource distribution instruction information.Also, UE uses institute
The optimal beam of determination is pointed to receive the accidental access response message.
Then, in step P3, UE uses Physical Uplink Shared Channel (Physical Uplink
Shared Channel, PUSCH) random accessing message is sent to eNB, the Stochastic accessing disappears
Breath includes the identification information of the UE.
Then, in step P4, eNB uses Physical Downlink Shared Channel (Physical
Downlink Shared Channel, PDSCH) send to be identified comprising the UE to the UE and believe
The contention resolution message of breath, to confirm to attempt to use multiple UE's of same random access resource
Conflict has been solved, and random access procedure is completed.
Although the program can reach beam forming gain higher, the program needs UE many
The secondary beam position for repeating to send targeting sequencing to determine optimal reception or send data so that
The process of the transmission targeting sequencing is more long, extends the time of random access procedure, when special
In the case of UE to be accessed is a fairly large number of, may result in the UE more than comparing cannot succeed
Access.Also, determine that optimal wave beam refers in the program based on the access request of single UE
Always set up up connection, and beam position determined by being directed to each UE be probably it is different,
Therefore further increase and extend random access procedure and the complexity implemented.
