Description
Technical field
The present invention relates to moving communicating field, especially in Long Term Evolution (LTE, Long Term Evolution) system
A kind of semi-persistent scheduling (SPS, Semi-Persistent Scheduling) is activated and the method and apparatus of deexcitation.
Background technology
In LTE communication system, it is proposed that the concept of full Internet protocol (IP, Internet Protocol) network,
Voice service is made to be evolved into ip voice (VoIP, the Voice over IP) business of data field.But due to voice user
Quantity the hugest, LTE uses again the resource distribution mode of shared scheduling, and every time transmission is required for the control being correlated with
Information processed, so the expense of the information of control is crossed senior general and is likely to become restriction LTE system and caned the number of users supported simultaneously, reaches
The bottleneck of the throughput of system arrived.The business of VoIP type, its data package size is more fixing, and the time of advent, interval met one
The real-time (the typical voice service cycle is usually 20ms) of set pattern rule.For this characteristic, LTE system introduces one
Plant new scheduling mode SPS.
SPS mode refers to during the scheduled transmission of LTE system, and base station (eNB, evolved Node B) adjusts initial
Spend and indicate subscriber equipment by Physical Downlink Control Channel (PDCCH, Physical Downlink Control Channel)
The schedule information that (UE, User Equipment) is current, including Resource Block (RB, Resource Block) information, adjusts
System and coding strategy (MCS, Modulation and Coding Scheme) information, hybrid automatic repeat-request (HARQ,
Hybrid Automatic Repeat Request) information etc..The mode that UE scrambles according to PDCCH, identification is semi-static
Scheduling, if scrambling with semi-static cell-radio network mark, then it is assumed that be the initial schedule of SPS, and preservation is worked as
Front schedule information, carries out transmission or the reception of this business datum on identical running time-frequency resource position every the fixing cycle.
Thus it is seen that use semi-persistent scheduling transmission, the feature that voice packets periodically arrives can be made full use of, once
Authorizing, the cycle uses, and can effectively save LTE system for dispatching the PDCCH resource of instruction, such that it is able at not shadow
While ringing speech quality and systematic function, support more voice user, and the business into dynamic dispatching that remains able to is protected
Stay certain control information for use.
Illustrating with typical VoIP business, its packet arrival cycle is 20ms, as long as then base station is by arranging semi-static tune
In the cycle (as a example by 20ms) of degree, then indicating to UE semi-persistent scheduling with PDCCH, UE is i.e. according to the instruction of PDCCH
Carry out this scheduling transmission of data or reception, and after 20ms, enterprising in identical running time-frequency resource position
The transmission of the newly arrived VoIP data bag of row or reception.
The up SPS that current LTE system realizes activates and specifically includes that implicit expression deexcitation and explicit deexcitation with anti-activating method:
(1) implicit expression deexcitation
The implicit expression deexcitation of up SPS, needs up-link wireless network user's layer (RNLU, Radio Network Layer User)
The whether deexcitation of medium education (MAC, Media Access Control) layer is notified according to the quantity receiving sky bag
The SPS resource of UE.Wherein, empty bag refers to not comprise MAC Service Data Unit (SDU, Service Data Unit) number
According to.Continuously the threshold value of empty bag by wireless network control layer (RNLC, Radio Network Layer Control) under
When sending out SPS configuration, together it is handed down to RNLU.Deexcitation message informing is provided by RNLU to the SPS of MAC, MAC release UE
Source.
(2) the explicit deexcitation of UE
When the SPS business of UE has and only VoIP, and enter quiet period, it may be assumed that corresponding during continuous 4 SPS new biographies
Medium Access Control (MAC) Protocol Data Unit (PDU, Protocol Data Unit) comprises lower the patrolling of the priority of logical channels than VoIP
Collect the data of channel, but do not comprise the data of logic channel corresponding for VoIP, the SPS resource of now MAC release UE.
VoIP business is being propped up at packet data convergence protocol (PDCP, Packet Data Convergence Protocol)
After holding ROHC function, because the quiet lotus of voice packet is little, the proportion of head is relatively big, voice packet header after compression, voice packet big
Little meeting changes, and in this case, UE can be by reactivation repeatedly, and existing method can not solve this problem very well.With
Time open robustness header compression (ROHC, Robust Header Compression) the most incidentally can produce ROHC feedback bag.
Due to the existence of ROHC feedback bag, the judgement of up explicit activation and deexcitation can be disturbed, thus cause the activation of SPS with
Deexcitation is more frequent.
