The present invention proposes a kind of deactivated method of carrier activation, include: carrier activation or deactivated MAC Control Element of the UE reception from eNB and carry out corresponding operation, the MAC Control Element is using the existing A/D MAC CE and/or A/D MAC CE newly defined.The A/D MAC CE that the present invention is defined by the extension to existing A/D MAC CE and/or newly meets the carrier activation deactivating operation demands of 32 carrier aggregation scenes.
Description
Technical field
The present invention relates to wireless communication field more particularly to a kind of deactivated methods of carrier activation.
Background technique
With the development of wireless mobile telecommunication technology, people propose higher and higher to high-speed, low latency, low cost
It is required that.LTE (Long Term Evolution) project just produces in this context, pursue higher peak rate and
Shorter propagation delay time.
The main performance target of LTE project includes: to be capable of providing downlink 100Mbps, uplink in 20MHz spectral bandwidth
The peak rate of 50Mbps improves the performance of Cell Edge User, improves cell capacity；System delay is reduced, in user plane
Portion's unidirectional transmission time delay is lower than 5ms, controls plane and is lower than 50ms from sleep state to state of activation transit time, from resident state
Transit time to state of activation is less than 100ms；Support the MPS process of 100Km radius；It can be used for 350Km/h high-speed mobile
The access service of family offer > 100kbps；Support pairs of or non-paired frequency spectrum；Support bandwidth varying, maximum 20M bandwidth.
LTE is in the network architecture using the simple squamous all-IP network for being made of access net eNB (Evolved Node B)
Network structure, this structure are conducive to simplify network and reduce delay, realize low time delay, the requirement of low complex degree and low cost.
ENB include physical layer, MAC (Medium Access Control) layer, RRC (Radio Resource Control), scheduling,
Access control, carrying control, access mobile management etc..Grid (Mesh) mode direct interconnection will be used between eNB and eNB,
Gradually level off to typical IP broadband network structure.
In physical-layer techniques, LTE uses OFDM (Orthogonal Frequency Division
Multiplexing), advanced Radio Transmission Technology and the base such as MIMO (Multiple Input Multiple Output)
In the link circuit self-adapting scheduling mode and interference coordination technique of channel.The rate and cell throughout of user are further improved,
Improve cell-edge performance.
With the development of wireless communication technique and the further serious hope of low time delay, high-speed, introduced in the LTE-A stage
New technology, such as carrier wave polymerization CA (Carrier Aggregation), relay Relay technology, multipoint cooperative CoMP
(Coordinated Multipoint)、eICIC(Enhanced Inter-Cell Interference Coordination)
Etc. wireless technologys.
Carrier wave polymerization CA is introduced into LTE-A in the R10 stage, supports the carrier wave polymerization of most 5 carrier waves.Into one in R11
Step enhancing CA supports TDD (Time Division under more TA (Time Advance) scene and different uplink and downlink proportion scenes
Duplexing) the carrier wave polymerization between cell.It is further enhanced in R12 and supports FDD (Frequency Division
Duplexing) the carrier wave polymerization between TDD different systems cell.
In the R13 stage in order to support higher rate, it is desirable that could support up the polymerization of 32 carrier waves.The version before R13
During carrier activation deactivates, using the activation deactivating operation of the progress carrier wave of MAC CE mode, MAC CE format such as Fig. 1 institute
Show, only the carrier wave of state of activation could service propagation data for UE, be unable to UE transmission data for deactivated carrier wave.Such as
Carrier activation shown in FIG. 1 deactivates in MAC CE, and R indicates bit reserved, and the carrier wave that C1 indicates that carrier index number is 1 swashs
Otherwise deactivation status living indicates to activate the carrier wave, other bit are similar if value is that 0 expression deactivates the carrier wave.It is existing
There is carrier activation in technology to deactivate MAC CE and its logic channel ID:11011.
Since the maximum quantity of the carrier wave polymerization of version before is 5 carrier waves, so deactivating MAC in design carrier activation
When CE, 8 carrier wave scenes are at most considered, for the 32 carrier wave scenes required in R13, existing MAC CE format no longer meets
Demand needs to redefine.
