Abstract

An objective of the present invention is to provide a method and apparatus for configuring DRX for a user equipment in a dual/plural connectivity wireless communication system. In the current 3GPP standard, the user equipment is not supported to perform a serving connection simultaneously to a plurality of cells at different nodes. Although there are a plurality of serving cells in the case of carrier aggregation, there is no significant gain for configuring DRX separately on respective carriers because there is only one common MAC layer and the upper layer data are multiplexed by carriers. However, for the dual/plural connectivity, different traffics will be transmitted over different base stations (even the same traffic may be transmitted in different base stations, it is likely that different base stations transmit multiple kinds of traffics; therefore, different base stations will transmit different traffics), such that configuring DRX separately will have a significant gain. The present invention determines a configuration pattern for DRX configuration for the user equipment based on the characteristics of dual/plural connectivity to perform DRX configuration to the user equipment better, which satisfies QoS demands of different traffics and meanwhile meets the objective of saving power.

Description

Method and device for configuring DRX for user equipment in dual/multi-connect wireless communication system

The present invention relates to the field of communication technologies, and more particularly to a technique for DRX configuration for user equipment in a dual/multi-connected wireless communication system.

At present, as low-power nodes can bring gains in capacity amplification and blind spot coverage, more and more research will focus on the deployment and enhancement of small cells covered by low-power nodes. Here, the low power node may be a small base station (Small eNB, SeNB for short), and examples include, but are not limited to, low power base stations such as Pico and Femto. In 3GPP R12, a new research item "Small Cell Enhancements for E-UTRA and E-UTRAN Higher-layer aspects" ("Small Cell Enhancement for E-UTRA and E-UTRAN High Level Aspects") has been approved and One important point is to support dual/multiple connectivity to the macro cell (the cell covered by the macro base station) and the small cell layer.

Dual/multiple connection refers to one or two/multi macro cells Each of the macro cell and the small cell has a different function, for example, a connection with an MME (Mobility Management Entity). The macro cell is used as an anchor cell that provides good coverage, and the small cell can implement data offload/split from the macro cell.

At this stage, for dual/multiple connections, the user equipment has only one RRC (radio resource control) state, such as RRC idle state or RRC connected state. In the RRC connection state, DRX (Discontinuous Reception) is a mechanism for better saving the battery power of the UE. The DRX configuration can balance the power consumption of the user equipment with the quality of service QoS. The longer the duration of the long/short DRX cycle, the better the power savings achieved, but this power savings is at the expense of service latency and introduces relatively large delays. Since different services have different delay requirements, it is better to configure DRX separately for different types of services from the perspective of service characteristics. For dual/multiple connections, different types of services can be supported to operate in different modes, such as a macro base station (MeNB) and a small base station (SeNB).

Therefore, for a user equipment with dual/multiple connections with a macro base station and a small base station, how to configure the DRX of the user equipment is essential.

In existing In the 3GPP standard, a user equipment is not supported and simultaneously connected to a plurality of cells at different nodes, although in the case of CA (Carrier Aggregation), there are multiple serving cells, but there is only one common MAC layer. The upper layer data is carrier multiplexed, so there is no significant gain in separately configuring DRX on each carrier. However, for dual/multiple connections, different services will be transmitted by different base stations (even if the same service can be transmitted on different base stations, but different base stations may transmit multiple services, so different base stations will transmit differently.

According to the configuration mode, the DRX configuration of the user equipment is better. It meets the QoS requirements of different services and can meet the purpose of power saving.

In step S101, the macro base station and the small base station respectively perform DRX configuration for the user equipment; in step S102, the user equipment connects to the macro base station and the small base station. Perform separate DRX programs separately.

Here, the wireless communication system does not need to consider the number of receivers in the user equipment, but directly performs the DRX configuration for the user equipment by the macro base station and the small base station.

According to another aspect of the present invention, there is also provided a method for DRX configuration for a user equipment in a dual/multi-connected wireless communication system, wherein the wireless communication system comprises a user equipment and is connected to the user equipment At least two base stations, the at least two base stations including at least one macro base station and at least one small base station.

Specifically, the macro base station and the small base station agreement to perform DRX configuration for the user equipment; wherein, the manner of the agreement configuration includes: - the macro base station performs DRX configuration on the user equipment according to the configuration related information corresponding to the small base station, combined with the radio bearer information and the connection related information transmitted by the macro base station.

Preferably, the configuration related information corresponding to the small base station includes any one of the following: - the DRX candidate configuration information that is configured by the small base station for the user equipment candidate; - the radio bearer transmitted by the small base station Information and connection related information.

Here, the wireless communication system still does not need to consider the number of receivers in the user equipment, but directly configures the DRX configuration for the user equipment by the macro base station and the small base station.

Specifically, the manner in which the macro base station and the small base station protocol perform DRX configuration for the user equipment includes but is not limited to:

1) The small base station actively sends the wireless bearer information and the connection related information transmitted by the small base station to the macro base station, and the macro base station receives the wireless bearer information and the connection related information transmitted by the small base station, and then combines the The radio bearer information and connection related information transmitted by the macro base station are integrated into the DRX configuration of the user equipment.

2) the macro base station sends a configuration request to the small base station, and the small base station returns, according to the configuration request, the radio bearer information and the connection related information transmitted by the small base station to the macro base station, and the macro base station receives the After the wireless bearer information and the connection related information transmitted by the small base station, combined with the wireless bearer information and the connection phase transmitted by the macro base station itself The information is comprehensively configured for DRX configuration of the user equipment.

3) The macro base station acquires the radio bearer information and the connection related information transmitted by the small base station when the dual/multiple connection is established, and further, the macro base station according to the radio bearer information and connection transmitted by the small base station Relevant information, combined with the wireless bearer information and connection related information transmitted by the macro base station itself, comprehensively configure DRX for the user equipment.

4) The small base station first performs candidate DRX configuration for the user equipment according to the radio bearer information and connection related information transmitted by itself, obtains DRX candidate configuration information, and actively sends the DRX candidate configuration information to the macro base station, and the macro base station receives The DRX candidate configuration information is combined with the radio bearer information and the connection related information transmitted by the macro base station to perform DRX configuration for the user equipment.

5) The small base station first performs candidate DRX configuration for the user equipment according to the radio bearer information and connection related information transmitted by itself, and obtains DRX candidate configuration information; the macro base station sends a configuration request to the small base station, the small base station According to the configuration request, the station returns the configured DRX candidate configuration information to the macro base station, and the macro base station receives the DRX candidate configuration information, and combines the radio bearer information and the connection related information transmitted by the macro base station itself. Integrated DRX configuration for the user equipment.

Here, the interaction between the macro base station and the small base station, for example, through the Xn interface, transmits required information, such as DRX candidate configuration information, configuration request, radio bearer information, and connection related information. The connection related information, such as the power capability of the user equipment, the willingness to save power, etc., and the connection Related information.

3 illustrates a flowchart of a method for DRX configuration for a user equipment in a dual/multi-connected wireless communication system in accordance with still another aspect of the present invention; wherein the wireless communication system includes a user equipment and the user equipment At least two base stations are connected, the at least two base stations including at least one macro base station and at least one small base station.

In step S301, the macro base station and/or the small base station acquires the number of receivers in the user equipment reported by the user equipment; in step S302, the macro base station is determined according to the number of the receivers. a configuration mode of performing DRX configuration with the small base station for the user equipment; in step S303, according to the configuration mode, the macro base station and the small base station perform the configuration mode for the user equipment Corresponding DRX configuration.

Here, the wireless communication system needs to consider the number of receivers in the user equipment, and according to the number of the receivers, determine a configuration mode for DRX configuration of the user equipment.

For example, the user equipment reports the number of receivers on the macro base station, and the macro base station sends the number of the receivers to the corresponding small base station, for example, through the Xn interface; or the user equipment The number of receivers is reported to the small base station, and the small base station transmits the number of the receivers to the corresponding macro base station, for example, through the Xn interface; or the user equipment directly directly counts the number of the receivers. Report to the macro base station and the small base station.

Preferably, when the number of receivers in the user equipment is greater than a first predetermined number of thresholds, the configuration mode is determined to be that the macro base station and the small base station respectively perform DRX configuration for the user equipment; subsequently, The user equipment performs separate DRX procedures for each of the connections to the macro base station and the small base station.

For example, assuming that the first predetermined number of thresholds is 0, when the number of receivers in the user equipment is greater than the first predetermined number of thresholds, that is, as long as the receiver includes the receiver, the macro base station and the small base station Perform DRX configuration for the user equipment separately.

For another example, if the first predetermined number threshold is 1, then when the number of receivers in the user equipment is greater than the first predetermined number threshold, if the user equipment has two or more receivers, then the macro The base station and the small base station respectively perform DRX configuration for the user equipment.

Preferably, when the number of the receivers is less than a second predetermined number of thresholds, the configuration mode is determined to be that the macro base station and the small base station agree to perform DRX configuration for the user equipment.

For example, assuming that the second predetermined number of thresholds is 2, when the number of receivers in the user equipment is less than the second predetermined number of thresholds, if the user equipment has only one receiver, the macro base station and the small base station protocol Perform DRX configuration for the user equipment.

Here, the first predetermined number of thresholds and the second predetermined number of thresholds are preset by the wireless communication system, for example.

More preferably, when the wireless communication system determines that the configuration mode is that the macro base station and the small base station agree to perform DRX configuration for the user equipment. When the macro base station and the small base station agree to perform DRX configuration for the user equipment. Specifically, the macro base station acquires DRX candidate configuration information from the small base station according to the configuration mode, where the DRX candidate configuration information is configured by the small base station for the user equipment candidate; subsequently, the The macro base station performs DRX configuration on the user equipment according to the DRX candidate configuration information, combined with the radio bearer information and the connection related information transmitted by the macro base station. At the same time, the macro base station is synchronized with the small base station.

The manner in which the macro base station obtains the DRX candidate configuration information from the small base station includes but is not limited to:

1) After performing the candidate DRX configuration for the user equipment and obtaining the DRX candidate configuration information, the small base station actively sends the DRX candidate configuration information to the macro base station. For example, the small base station knows the number of receivers in the user equipment, such as the user equipment directly sent to the small base station, or the macro base station knows the quantity and then forwards to the small base station, and the The small base station learns that the configuration mode is that the macro base station and the small base station agree to perform DRX configuration on the user equipment, and the small base station first performs candidate DRX configuration for the user equipment, obtains DRX candidate configuration information, and actively The DRX candidate configuration information is sent to the macro base station.

2) The macro base station sends a configuration request to the small base station, and the small base station returns the DRX candidate configuration information configured for the user equipment candidate to the macro base station based on the configuration request. For example, the user equipment only sends the number of receivers on the macro base station to the macro base station. After obtaining the number of the receivers, the station knows that the configuration mode is that the macro base station and the small base station agree to perform DRX configuration for the user equipment, and therefore, the macro base station sends a configuration request to the small base station to request the small Base station DRX candidate configuration information.

More preferably, the macro base station may further combine the radio bearer information and the connection related information transmitted by the small base station acquired according to the configuration mode according to the configuration mode, and combine the macro base. The radio bearer information and connection related information transmitted by the station are configured for DRX configuration of the user equipment.

More preferably, the macro base station may further acquire, according to the configuration mode, radio bearer information and connection related information transmitted by the small base station from the small base station; subsequently, the macro base station is configured according to the small base The radio bearer information and the connection related information transmitted by the station are combined with the radio bearer information and the connection related information transmitted by the macro base station to perform DRX configuration for the user equipment.

Similarly, the macro base station obtains the wireless bearer information and the related information transmitted by the small base station from the small base station, including but not limited to:

1) The small base station actively sends the wireless bearer information and connection related information transmitted to the macro base station.

2) The macro base station sends a configuration request to the small base station, and the small base station returns the transmitted radio bearer information and the connection related information to the macro base station based on the configuration request.

Here, the interaction between the macro base station and the small base station, for example, The Xn interface sends information to be transmitted, such as DRX candidate configuration information, configuration request, radio bearer information, and connection related information. The connection related information is, for example, the power capability of the user equipment, the power willingness, and the like.

For the user plane, there are three options for splitting user plane data: Option 1: S1-U terminates in the SeNB (ie, the small base station is connected to the serving gateway S-GW and transmits data therewith) ): Option 2: S1-U terminates in the MeNB (ie the macro base station is connected to the serving gateway S-GW and transmits data therewith), there is no bearer split in the RAN (Radio Access Network): and option 3: S1-U terminates in the MeNB, and there is bearer splitting in the RAN.

Taking one of Option 1 and Option 2 of the user plane as an example, for dual/multiple connections, different services transmitted on the MeNB and the SeNB have different QoS requirements, assuming only one carrier, and only one at the user equipment end. The receiver, the two connections with the MeNB and the SeNB will operate in a TDM (Time-Division Multiplexing) mode. If the time interval period of the TDM is greater than the DRX period, there is no problem; but if the time period of the TDM is less than or close to the DRX period, the connection between the user and the MeNB and the SeNB alternates in time, when the connection is switched from the connection with the MeNB to the SeNB. On the upside, assuming that the target connection will be in the "on" state, and the source connection is in the "off" state, the user will be forced to transition from the "off" state to the "on" state. "status. The opposite is also true. Therefore, the gain obtained by separately configuring DRX will not be significant. In the above case, the change of the gain of the method of configuring the same DRX and the manner of separately configuring the DRX is small. The DRX can be configured separately from the macro base station and the small base station, and the same DRX can be configured.

Specifically, assuming that the wireless communication system does not consider the number of receivers at the user equipment end, the macro base station and the small base station respectively perform DRX configuration for the user equipment.

Assuming that the wireless communication system needs to consider the number of receivers at the user equipment end, the configuration mode is determined according to the number of receivers in the user equipment, in combination with the first or second predetermined number of thresholds. For example, when there is only one receiver in the user equipment, and the second predetermined number threshold is 2, the number of the receiver is less than the second predetermined number threshold, and the configuration mode determines that the macro base station and the small base station are in agreement The user equipment performs DRX configuration. The specific implementation manner of the protocol configuration herein is the same as that of the foregoing embodiment, and therefore is not described herein again, and is hereby incorporated by reference.

Or, assuming that the wireless communication system does not consider the number of receivers on the user equipment side, the macro base station and the small base station agree to perform DRX configuration for the user equipment, that is, configure the same DRX.

Taking another embodiment of Option 1 and Option 2 of the user plane as an example, for dual/multiple connections, different services transmitted on the MeNB and the SeNB have different QoS requirements, assuming two or more carriers, and the user The device has only one receiver, which is similar to the case of CA (Carrier Aggregation) with a single receiver. If the connection between the user equipment and the macro base station and the connection to the small base station, the duration of "on" With little or no overlap, the user equipment has to be "on" most of the time, so configuring DRX separately does not have a better gain than the normal way of configuring DRX. Therefore, the DRX can be configured separately from the macro base station and the small base station, and the same DRX can be configured.

Specifically, assuming that the wireless communication system does not consider the number of receivers at the user equipment end, the macro base station and the small base station respectively perform DRX configuration for the user equipment.

Assuming that the wireless communication system needs to consider the number of receivers at the user equipment end, the configuration mode is determined according to the number of receivers in the user equipment, in combination with the first or second predetermined number of thresholds. For example, when there is only one receiver in the user equipment, and the second predetermined number threshold is 2, the number of the receiver is less than the second predetermined number threshold, and the configuration mode determines that the macro base station and the small base station are in agreement The user equipment performs DRX configuration. The specific implementation manner of the protocol configuration herein is the same as that of the foregoing embodiment, and therefore is not described herein again, and is hereby incorporated by reference.

Or, assuming that the wireless communication system does not consider the number of receivers on the user equipment side, the macro base station and the small base station agree to perform DRX configuration for the user equipment, that is, configure the same DRX.

Taking another embodiment of Option 1 and Option 2 of the user plane as an example, for dual/multiple connections, different services transmitted on the MeNB and the SeNB have different QoS requirements, assuming that the user equipment has multiple receivers, and the macro The separate configuration of the DRX between the base station and the small base station will have significant gain, so the macro base station and the small base station are separately configured for the user equipment. DRX configuration.

Specifically, assuming that the wireless communication system does not consider the number of receivers at the user equipment end, the macro base station and the small base station respectively perform DRX configuration for the user equipment.

Assuming that the wireless communication system needs to consider the number of receivers at the user equipment end, the configuration mode is determined according to the number of receivers in the user equipment, combined with the first or second predetermined number threshold. For example, when there are multiple receivers in the user equipment, and the first predetermined number threshold is 1, the number of the receivers is greater than the first predetermined number threshold, and the configuration mode is determined to be that the macro base station and the small base station respectively Perform DRX configuration for the user equipment. The specific implementation manners of the DRX configuration for the user equipment in the macro base station and the small base station are the same as those in the foregoing embodiment, and therefore are not described here, and are included herein by reference.

Taking another embodiment of option 3 of the user plane as an example, it is assumed that there are multiple radio bearers on the macro base station for transmission, and one or more radio bearers are simultaneously transmitted on the macro base station and the small base station. This will be similar to the case of option 1 and option 2 of the user plane. The gain of the separately configured DRX is also dependent on the number of receivers in the user equipment. Assuming there is only one receiver, the gain of the separately configured DRX is limited or even no gain. But assuming that the user equipment has multiple receivers, the gain will be very significant since the DRX configuration is performed separately based on the characteristics of the traffic transmitted on each base station. Here, the specific implementation manner of the macro base station and the small base station, or the DRX configuration for the user equipment is the same as that of the foregoing embodiment, and therefore will not be described here, and is included in the reference. this.
