Description

A carrier activation method, device and system

technical field

The present invention relates to the technical field of communications, and in particular to a carrier activation method, device and system.

Background technique

As a subsequent enhanced version of 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) LTE (Long Term Evolution, Long Term Evolution) technology, LTE-A (LTE Advanced, Advanced Long Term Evolution) system introduces carrier aggregation (carrier aggregation) technology to support higher bandwidth transmissions.

The basic principle of carrier aggregation is to meet higher bandwidth requirements by aggregating two or more working carriers together. After the carrier aggregation technology is introduced, the number of working carriers in a cell changes from one to multiple, forming a multi-carrier communication scenario. In the carrier aggregation technology, multiple working carriers (uplink or downlink) are aggregated together to serve UE (User Equipment, user equipment) at the same time, instead of only one set of carriers in the LTE system and previous wireless communication systems. The base station manages and schedules multiple sets of working carriers in a unified manner, and switching between different working carriers in a base station is only a matter of resource allocation. The working carriers can be continuous or non-continuous. In order to be compatible with the LTE system, the maximum bandwidth of each working carrier is 20MHz, and the bandwidths between working carriers can be the same or different.

When the UE initially accesses the system or re-establishes RRC (Radio Resource Control, Radio Resource Control) configuration, the network side will configure the carrier available to the UE. When the UE can be used for uplink transmission or the system can be used for downlink communication When there are multiple carriers, if the UE has been turning on the receiver or transmitter corresponding to the multi-carrier, but the UE may not need to receive downlink data of a certain carrier or use a certain carrier for uplink transmission for a period of time, it will cause UE The waste of electricity, the energy saving performance is not good.

Considering that the multi-carrier application environment can be dynamically configured and changed according to the load of the UE and the network, the network side needs to use the multi-carrier activation/deactivation scheme to promptly notify the UE to activate a certain carrier, and through the activated carrier Receive or send data. Currently, there is no clear carrier activation solution in the prior art.

The format of the MAC PDU used in the carrier activation method in the embodiment of the present invention is shown in FIG. 3 .

Table 1 LCID format table

The carrier activation method in the embodiment of the present invention will be described in detail below in combination with the above application scenarios.

As shown in FIG. 5, it is a flow chart of a carrier activation method in Embodiment 3 of the present invention, which specifically includes the following steps:

In step 501, the network device configures a MAC PDU carrying activation information corresponding to available carriers of the user equipment, and the MAC PDU carries activation information through a MAC CE and a MAC sub-header corresponding to the MAC CE.

Step 502, the network device sends the MAC PDU carrying the activation information to the user equipment.

Step 503, the user equipment receives a MAC PDU from the network device, and the MAC PDU carries activation information through the MAC sub-header corresponding to the MAC CE.

Step 504, the user equipment activates and/or deactivates the carrier configured on the network side according to the activation information carried in the MAC sub-header.

The design of each field of MAC CE related to multi-carrier activation and/or deactivation includes the following two schemes:

(1) Use the MAC sub-header to indicate the activation and/or deactivation process of all available carriers of the UE.

Among them, the LCID in the sub-header adopts one of the currently reserved bit design methods, such as 01011, to indicate the activation and/or deactivation process of all available carriers of the UE, and there is no need to design a special MAC CE field content, that is, The MAC CE padding bits corresponding to the sub-header are zero. LCID may not indicate the type of activation information. After receiving the LCID, the UE may activate and/or deactivate the carrier according to the current state of the carrier indicated by the LCID. Specifically, if the current state of all available carriers of the UE is activated, the UE deactivates all available carriers; if the current state of all available carriers of the UE is deactivated, the UE activates all available carriers.

In addition, when the LCID indicates the activation and/or deactivation process of all available carriers of the UE, the R bit in the sub-header may also be used to indicate whether the signaling is activation or deactivation signaling. The encoding scheme may be: when the R bit is set to 1, it indicates that the signaling is carrier activation signaling; when the R bit is set to 0, it indicates that the signaling is carrier deactivation signaling. Of course, it is also possible to adopt a configuration opposite to the above encoding scheme.

In addition, when the LCID indicates the activation and/or deactivation process of all available carriers of the UE, the LCID can also be used directly to distinguish signaling as activation signaling and/or deactivation signaling, for example, 01011 indicates carrier activation, and 01101 indicates carrier deactivation Activate signaling.

(2) Use the MAC sub-header field to indicate the identity of the carrier that the UE needs to activate and/or deactivate.

Wherein, the LCID in the sub-header adopts one of the currently reserved bit design methods, such as 01011, to indicate that the UE needs to activate and/or deactivate the carrier identifier of the carrier in the MAC CE corresponding to the sub-header. LCID may not indicate the type of activation information. After receiving the LCID, the UE may activate and/or deactivate the carrier according to the current state of the carrier indicated by the LCID. Specifically, if the current state of the carrier indicated by the LCID of the UE is an activated state, the UE deactivates the carrier; if the current state of the carrier indicated by the LCID of the UE is a deactivated state, the UE activates the carrier .

In addition, when the LCID indicates that the UE needs to activate and/or deactivate the identity of the carrier, the R bit in the sub-header can also be used to indicate whether the signaling is an activation or deactivation signaling; the encoding scheme is: the R bit is set to 1, It indicates that the signaling is carrier activation; when the R bit is set to 0, it indicates that the signaling is carrier deactivation signaling. Of course, the setting opposite to the above encoding scheme may also be adopted.

In addition, the activated and/or deactivated carrier identifier may also be carried by the MAC CE, or other information that may represent the corresponding activated carrier. And the LCID is used to distinguish signaling as activation signaling and/or deactivation signaling. Specifically, the above-mentioned LCID may use a reserved bit design method to indicate that the type of activation information is activation signaling and/or deactivation signaling. After receiving the LCID, the UE may, according to the current state, to activate and/or deactivate the carrier. If the current state of the carrier indicated by the MAC CE of the UE is activated, the UE deactivates the carrier; if the current state of the carrier indicated by the MAC CE of the UE is deactivated, the UE activates the carrier.

The above LCID can also use two reserved bit modes to indicate the type of activation information, one reserved bit mode is used to indicate that the type of activation information is activation signaling, and the other reserved bit mode is used to indicate activation information The type of is deactivation signaling. For example, 01011 indicates that the type of activation information is activation signaling, and 01101 indicates that the type of activation information is deactivation signaling.

Embodiments of the present invention use MAC CE and corresponding sub-headers to design carrier activation and/or deactivation signaling, so that UE can reduce UE decoding delay and improve system performance under the premise of ensuring the validity of the signaling reception. Save the power of the UE; at the same time, use LCID or reserved bits to distinguish activation and/or deactivation signaling, which can reduce bit overhead.
