Up-link license distribution and priority of logical channels flow in LTE
In LTE, when UE medium education (Medium Access Control) layer receive physically come it is up
After link license (Uplink grant), multiplexed combinations entity (the Multiplexing and Assembly in MAC entity
Entity) according to the up-link indicated physical resource can be permitted to be taken out from the data buffer storage of each logic channel accordingly
Data fill up distributed resource.Briefly, data corresponding to a logic channel can regard a kind of business as
Data, UE are configured with multiple different logic channels, then the UE has inhomogeneous business simultaneously.ENB can configure each logic
The priority of channel, referred to as priority of logical channels, in the resource in distributing up-link license, priority of logical channels is high
Logical channel data can preferentially be distributed resource.In general, the business higher to delay requirement is often allocated higher
Priority.Inhomogeneity business is realized by the resource distribution mode (i.e. bgical channel priority flow) of this differentiation priority
Quality of service requirement.
In the case where supporting carrier aggregation (Carrier Aggregation, CA), UE has multiple serving cells simultaneously
(or being server carrier), in same TTI, each server carrier may be that the UE distributes up-link license, i.e., should
UE MAC layer can receive multiple up-links license of the physical layer from different server carriers simultaneously.In this case, how
The indicated resource of multiple up-links license is allocated between each logic channel, for example multiple up-links are permitted
A bigger resource is combined into be allocated, or the allocation order between the license of multiple up-links, and by MAC layer
MAC control elements (Control Element, CE) be assigned in the resource of which up-link license, be all that UE is realized and asked
Topic；I.e. agreement provides, these problems oneself determine inside UE.
Bj in LTE in priority of logical channels flow is calculated
As described above, MAC entity can be from high to low each logical channel assignment resource according to the priority configured, it is every
Individual logical channel assignment how many resources (that is, the logic channel can transmit how many data in the TTI) can by parameter Bj come
Realize.
MAC entity safeguards a Bj value to each logic channel, can simply be interpreted as the Bj values and indicate logic letter
How many data volume that can transmit of road.Existing protocol provides that Bj increases at each TTI, and incrementss are Prioritized Bit rate
(Prioritized Bit Rate, PBR) is multiplied by TTI length, i.e., the increase PBR data volumes per 1ms.When multiplexed combinations entity is to be somebody's turn to do
After logical channel assignment can transmit the resource of X size data amounts, correspondingly also Bj can be subtracted X.
As described above, in the case of CA, it is that UE realizations are asked that how MAC, which distributes multiple up-links to be permitted denotable resource,
Topic, because corresponding up-link license can meet identical quality of service requirement on each server carrier, one
The data of logic channel can obtain identical service quality in any one server carrier transmitted over resources.Present invention invention
People has found that, when introducing sTTI, situation is then entirely different.STTI sPUSCH can provide service quality more more preferable than PUSCH,
For accurate, shorter time delay service can be provided.For the business that those time delays are urgent, it is more suitable for using corresponding to sPUSCH
Up-link granting resources transmit, and this is exactly the original intention that time delay reduces subject under discussion.
In addition, inventor also found, Bj can increase automatically in each TTI.After sTTI is introduced, when UE simultaneously
During using sTTI and TTI, according to described in existing protocol, Bj can increase in each TTI and each sTTI, and this causes excessive
Increase, so as to be impacted to the resource allocation of reality.
Technical scheme will be described in detail below.Hereinafter, unless illustrating, UE and UE MAC
Entity is in most cases used interchangeably.But it should be noted that, although in the following description, logic of the invention is believed
The preferential flow and method in road can perform in UE MAC entity, but in some other actual execution, it can also be used in UE
Handle and performed in other entities of same or similar function, the executive agent of the present invention program is not limited to MAC entity.
In the present invention, UE in the preferential flow of logical channels can by MAC control member (Control Element,
CE) it is included in MAC PDU corresponding to PUSCH, further, MAC CE can also be included in MAC corresponding to sPUSCH
In PDU.
