Description

Selection method, system, computer storage medium, the equipment of link communication mode

Technical field

The invention belongs to field of communication technology, it is related to a kind of selection method and system, more particularly to a kind of link communication Selection method, system, computer storage medium, the equipment of mode.

Background technique

Transmission reliability and time delay enhancing are two critical aspects of URLLC, it is defined as in TR 22.862 and TR Super reliable and low time delay communication in 38.913.In URLLC use-case, it is necessary to there is the reliability of superelevation that data packet is correctly received, Acceptance rate reaches 99.999%, and will be in the time delay target of setting.Even if using the shortest TTI that is discussed in RAN1 and HARQ RTT, it is also difficult to meet the delay requirement of URLLC.Therefore, it is necessary to advanced optimize the time delay newly eated dishes without rice or wine to support URLLC Service.A kind of method ensuring reliability is to support carrying duplication, its purpose is by the different identical numbers of path transmission According to packet, to reduce the time delay of HARQ.In 96 meetings of RAN2, packet replication is used with research under multi-connection framework is intended to With link selection mechanism, to reach the reliability requirement of URLLC.In 100 meetings of RAN2, we agree to support RLC AM SRB supports under packet replication and RLC UM mode SRB by dual link come packet replication by dual link and carrier wave polymerization under mode, and Agree to the packet replication that HRLLC is supported with LTE PDCP.

Although packet replication will have some improvement in terms of reliability and delay, due to agreement framework there is also Some disadvantages.Due to being assigned with dual resource, packet replication can consume more physical resources, and require on two paths Individual RLC/MAC/PHY processing (such as connection, segmentation, refitting, channel coding etc.).Therefore, when the channel item of two paths When part is good enough, packet replication may result in the waste of resource.It whether useful mobile with UE is replicated in the life cycle of load Property, local resource availability, backhaul load and time delay are related.For example, the X2 interface between the gNB of multi-connection experienced it is short Under the scene of temporary high load and/or high time delay, or there is a cell to use at high cell load (control and/or data) In the case where the mode of separating load, packet replication may be worthless.Therefore, network should be controlled using new method It is replicated in UE using PDCP.In packet replication, it is configured with the separating load of two paths, when duplication is activated, two paths The data packet of upper transmission copying.For packet replication, the duplication that the PDCP function support in transmitter is wrapped, and PDCP in receivers The removal of function support copy package.

The wireless environment newly eated dishes without rice or wine ratio LTE is caused to be easier the influence changed in view of disposing due to high-frequency, so Non-dynamic selection link mode may be not suitable for.Therefore, it newly eats dishes without rice or wine to be more likely to using dynamic link selection mechanism for 5G.It is right In the UE of a multi-connection, the link of transmission is that dynamic determines.Further, it is also possible to carry out using active and/or energetically chain The trigger mechanism that selecting is selected/switched.Such as:

Reaction equation link selection: after detecting the transmission failure in a connection, link selection is switched to another Connection.

Active link selection: selection another link of connection is triggered before connection failure occurs, such as base In the selection mechanism of channel state information.

Support that active link selection is all beneficial to time delay and spectrum efficiency.However, not due to information such as channel status Certainty, this mechanism are not always that may be implemented.So link selection mechanism cannot make full use of the multiplicity of two paths Property feature.

It, can be with assuming that there are both links (leg1 and leg2) to can be used for configuring transmission when UE is in dual link mode Using three kinds of communication patterns.Packet replication mode, link selection mode (single link communications mode) and separating load mode.One side Face, if as soon as an individually load is each operated with, then needing to define three loadtypes.In order to simplify loadtype Definition, these three operations can reuse identical loadtype, such as traditional separating load mode in DC.On the other hand, by Change in channel condition with the difference of wireless environment, especially on high frequency, the link-quality of both links is different have with Under several situations.In the case of different, it should using different operations come maximum system performance.For example, as leg1 and When the link quality of leg2 is good enough, i.e., case 1 the case where, be best selection using separating load mode, be for improving System capacity.For case 2 or 3, wherein the quality of connection of a link is good or can communicate that another is poor , link selection mode will be a better choice.The feelings not ideal when the quality of connection of both links for case 4 Under condition, packet replication mode may be the fine selection of a raising reliability.Therefore, how adaptive selection link communication mould Formula is problem to be solved come the allocation optimum for realizing network.
