Method, system and device for information transmission

The present invention relates to the field of wireless communication technologies, and in particular, to a method, system and device for information transmission.

With the evolution of technology and the increase of data services, the concept of small cells has been raised and received high attention. A small cell usually has a small coverage and a low transmission power. By deploying a small cell closer to the user, such as indoors and hotspots, the user's data rate can be increased.

According to the current research, the types of small cells are mainly divided into three types, small cells with independent attributes, small cells with non-independent attributes, and small cells with independent and non-independent dual attributes. Figure 1A and Figure 1B respectively give The small cell is not independent and independent work.

A heterogeneous network deployment scenario including a local evolved base station (Local eNB) and a macro evolved base station (Macro eNB) is shown in FIG. 1C. The Macro base station provides macro coverage, and the Local eNB provides hotspot coverage within the macro coverage. Figure 1C Heterogeneous network deployment scenario For the network architecture shown in the preceding figure, if the user equipment (User Equipment, UE) moves within the coverage of the Macro cell according to the existing mechanism, the Macro cell and the Local cell may be continuously executed. Switching operation. In order to avoid interruption of information transmission caused by frequent switching, one way is to let the UE The resources of the Local eNB and the Macro eNB can be aggregated at the same time, but the Radio Resource Control (RRC) connection is maintained under the Macro eNB, and the Local resource is only used for information transmission, that is, the control plane user plane separation technology, also called bearer separation. .

In the LTE-Advanced (LTE-A) system, the peak rate of the system is greatly improved compared to the Long Term Evolution (LTE) system, which requires downlink 1 Gbps and uplink 500 Mbps. Therefore, the LTE-A system needs to expand the available bandwidth of the user equipment, that is, to aggregate multiple consecutive or discontinuous carriers under the same evolved Node B (eNB) while serving the UE to provide the required rate. , as shown in Figure 1D. These aggregated carriers are also called Component Carriers (CCs). Each community can be a member carrier. To ensure backward compatibility, each carrier does not exceed 20 MHz at the maximum.

In carrier aggregation, one of the component carriers is configured as a primary carrier (Pcell or PCC), and the user equipment receives a Physical Downlink Control Channel (PDCCH) Common Search Space (CSS) on the primary carrier. A UE (specifically search space, UESS), where the common search space is used to transmit a PDCCH that schedules common control signaling, such as broadcast, paging, etc., and the UE search space is used to send scheduling signaling for the user, and the like. The other component carriers other than the primary carrier become the secondary carrier (Scell or SCC), and the user equipment receives only the PDCCH UE search space on the secondary carrier, and does not receive the PDCCH common search space. Moreover, the number of blind detections of the user equipment blindly detecting the PDCCH UE search space on the Pcell and the Scell is the same.

Depending on the spectrum usage, small cells will mainly use high frequency bands (eg 3.5 GHz or above), while Macro cells mainly use lower frequency bands (eg 2 GHz or below). because Therefore, the bearer separation working mode and the carrier aggregation can be used in combination, the control plane connection of the user equipment is maintained in the lower frequency band by the Macro service, and the user plane connection is maintained in the higher frequency band by the small cell service. In this solution, a component carrier (CC) connected to the Macro is used as a Pcell, and the user equipment mainly receives system broadcast, paging, RRC signaling, etc. on the CC; and the network is connected to the small cell. The CC functions as an Scell, and the user equipment receives only user plane control signaling, data, and the like on the CC.

In the combination of carrier aggregation and C/U separation, only control plane signaling is transmitted on the Pcell, and some high-level control signaling is not always sent, so the total amount of data on the Pcell is relatively low; the Scell is used to transmit users. Control signaling, data, etc. Since the small cell base station is closer to the user equipment, the signal quality is better. For users with high throughput requirements, a large amount of information transmission is performed on the Scell, so the total amount of data on the Scell is high. At present, user equipment needs to perform a large number of meaningless Pcell monitoring, thereby causing unnecessary energy consumption and reducing scheduling flexibility on the Scell.

In summary, at present, user equipment needs to perform a large number of meaningless Pcell monitoring, thereby causing unnecessary energy consumption and reducing scheduling flexibility on the Scell.

The present invention provides a method for information transmission, which is used to solve the problem that the user equipment existing in the prior art needs to perform a large number of meaningless Pcell monitoring, thereby causing unnecessary energy consumption and reducing scheduling flexibility on the Scell.

Due to a large number of meaningless Pcell listeners, in fact, Pcell has only a small amount of data transmission, resulting in unnecessary user equipment energy consumption, and a large number of meaningless cases due to the limited PDCCH blind detection capability of the user equipment. The blind detection of the Pcell PDCCH indirectly restricts the improvement of the PDCCH blind detection opportunity available on the Scell, thereby restricting the scheduling flexibility on the Scell. In the embodiment of the present invention, the network side device sends a downlink signal to the user equipment according to the monitoring information according to the monitoring position and/or the monitoring configuration information, thereby reducing the number of times the user equipment performs the meaningless Pcell monitoring, and reducing the energy consumption.

The embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

In the following description, the implementation of the cooperation between the network side and the user equipment side will be described first, and finally the implementation from the network side and the user equipment side will be described separately, but this does not mean that the two must cooperate with the implementation. In fact, When the network side is implemented separately from the user equipment side, the problems existing on the network side and the user equipment side are also solved, but when the two are combined, a better technical effect is obtained.

As shown in FIG. 2, the system for information transmission in the embodiment of the present invention includes: a network side device 10 and a user equipment 20.

The network device 10 is configured to determine the monitoring information on the target community configured for the user equipment, where the monitoring information includes the monitoring location and/or the monitoring configuration information, and sends a downlink signal to the user equipment according to the monitoring information; the user equipment 20 is configured to: The monitoring information on the target community configured by the network side device is determined, and the monitoring information is monitored according to the monitoring information, and the downlink signal sent by the network side device is received.

Preferably, the downlink signal sent by the network side device 10 may be one of the following downlink signals: a PDCCH signal, an enhanced physical downlink control channel (EPDCCH) signal, and a physical downlink shared channel (PDSCH) signal.

Preferably, the network side device 10 can configure the user equipment 20 with the monitoring information on the target community through the high layer signaling. The user equipment 20 receives the monitoring information on the target community configured by the network side device 10 through the high layer signaling.

The following describes the processing methods of monitoring information including different contents.

Method 1: The monitoring information includes the listening position.

Here, the listening position indicates the subframe to be monitored.

In the implementation, the sub-frame identifier can be used as the monitoring position. For example, if the sub-frame to be monitored is the sub-frame 6, the 6 can be used as the monitoring position; and the bit map can be used as the monitoring position, wherein One bit in the bitmap corresponds to a subframe, and the value of the bit identifies whether it is a subframe that needs to be monitored. For example, 0 means no, 1 means yes, subframe 6 and subframe 9 need to be monitored. The sub-frame, then the bitmap is 000001001.

It should be noted that the above two types of listening position expressions are only examples, and any information that can represent the subframes that need to be monitored can be used as the listening position.

The network side device 10 first determines, according to the listening position, a specific subframe set of the user equipment in the target community; and then sends a downlink signal to the user equipment 20 on the at least one subframe in the determined specific subframe set; Correspondingly, the user equipment 20 determines a specific subframe set in the target community according to the listening position, and performs monitoring on at least one subframe in the specific subframe set.

For the first mode, the network side device 10 configures the carrier aggregation user equipment 20 to monitor and receive data only in a part of the subframes on one Cell (or CC).

The network side device 10 can be configured by the high layer signaling to inform the user equipment 20 of the specific subframe set required on the Pcell (or each Cell), and the user equipment 20 is only in the specific subframe notified in the corresponding cell. Monitor and receive downlink data within the collection.

In the configured specific subframe set, the user equipment 20 listens to all PDCCHs and receives the PDSCH according to the scheduling situation; in other subframes outside the specific subframe set, the user equipment 20 does not receive any downlink signals.

When the target community is a PCell, the user equipment 20 needs to correctly receive the public information (such as system information, paging message, and the like) sent by the network side device on the Pcell. Therefore, the specific subframe set of the target community includes at least the sub-information. Box 0 and subframe 5.

When the target community is an SCell, if the user equipment 20 needs to listen to public information (such as system information, paging messages, etc.) in a certain Scell, the subframe included in the specific subframe frame of the target community can make the user equipment correct. Receive public information sent by the network side device.

In the implementation, the network side device 10 has a message other than the specific subframe frame set. The downlink signal is not sent on the frame; correspondingly, the user equipment 20 does not receive the downlink signal on the subframe other than the specific subframe set required. Or the network side device 10 sends the PDCCH CSS signal on the subframe except the specific subframe set; correspondingly, the user equipment 20 does not blindly check the PDCCH UESS on the subframe other than the determined specific subframe set. Or EPDCCH UESS, only PDCCH CSS is blindly detected, and only data scheduled by DCI in the PDCCH CSS is received.

Since the user equipment 20 does not monitor or only blindly check the PDCCH CSS in a subframe other than the specific subframe set of the target community, a preferred manner is that the user equipment 20 is in a specific subframe set of the target community. In the other subframes, the blind detection capability is used for PDCCH blind detection of other communities.

The monitoring includes the receiving of the control channel PDCCH or the EPDCCH, and the receiving of the data channel PDSCH. In the LTE system, the user equipment receives the control channel PDCCH or EPDCCH by means of blind detection.

Preferably, user equipment 20 may use some or all of the blind detection capabilities for PDCCH blind detection of other communities.

Preferably, the partial blind detection capability here is the capability of blind detection of the PDCCH UESS or EPDCCH UESS.

All the blind detection capabilities here include the ability to blindly check the PDCCH UESS or EPDCCH UESS, and the ability to blindly check other signals, such as the ability to blindly detect PDCCH CSS, and the ability to blindly check PDSCH.

The following describes an example of the first method.

For example, the network side device 10 can report in a bitmap manner through RRC signaling. It is known which subframes of the user equipment 20 must be monitored within a certain period of time (for example, each radio frame). As shown in Table 1 below, the network side device 10 configures the user equipment 20 to be monitored in the subframe {0, 4, 5, 9} of each radio frame on the Pcell. In other subframes {1, 2, 3, 6, 7, 8} other than the set, the user equipment 20 does not receive any downlink signals, or only blindly detects the PDCCH CSS and its scheduled data.

Further, in the subframe in which the cell does not need to be monitored, the PDCCH blind detection capability of the user equipment 20 may be allocated to other cells that need to be monitored. In the example of Table 1, when the user equipment 20 aggregates two carriers, the user equipment 20 only needs to completely monitor the Pcell in the specific subframe set {0, 4, 5, 9}, within the specific subframe set ( The sub-frame set 1), the allocation of the PDCCH blind detection in the Pcell and the Scell is the same as the prior art. For details, refer to the other subframes of the 3GPP TS 36.213 in the sub-frame set 1 (referred to as the sub-frame set 2). As the user equipment 20 does not need to monitor the Pcell, the PDCCH blind detection capability that can be vacated can be allocated to the Scell. The specific PDCCH blind detection capability can be redistributed in the following two ways:

1. All PDCCH blind detection capabilities of a subframe on the Pcell are allocated to the Scell. Table 2 and Table 3 respectively show the PDCCH blind detection configuration allocation on the Pcell and Scell in the above subframe set 2 in this manner.

2. Assign the exclusive PDCCH or EPDCCH blind detection capability of a subframe on the Pcell to the Scell. Tables 4 and 5 respectively show the sub-frame set 2 in this mode. The PDCCH blind check configuration allocation on the inner Pcell and the Scell.

Method 2: The monitoring information includes monitoring configuration information.

The monitoring configuration information here indicates the number of times that blind detection is required on each subframe.

In the implementation, the monitoring configuration information may be: the proportion of the number of times the user equipment performs blind detection on different target communities in a subframe, because the total number of blind detections of the user equipment on a subframe is determined, so the user The device 20 may determine the number of blind detections in different target communities according to the proportion of times; or the total number of blind detections performed by the user equipment on each target community, wherein the total number of blind detections of the multiple target communities is not greater than that of the user equipment. The maximum number of blind detections is 2CC. The number of times that the user equipment 20 configures the dedicated PDCCH or EPDCCH blind detection on the Pcell is 6, and the number of exclusive PDCCH or EPDCCH blind detection on the Scell is 26, as shown in Table 6 and Table. 7; or The number of times the user equipment performs blind detection for each aggregation level on each target community, wherein the total number of blind detections of the multiple target communities is not greater than the maximum number of times the user equipment can perform blind detection, assuming that the user equipment in each member carrier A plurality of aggregation levels {1, 2, 4, 8} need to be blindly checked. The total number of blind detections performed by the user equipment on each target community is the number of blind detections of the configured member carrier, that is, the aggregation level is not distinguished, and only the total is notified. The number of times; here is the number of blind checks for each aggregation level separately; or the proportion of the user equipment for blind detection in different target communities, such as proportional division, or non-equal division. Taking 2CC as an example, the equal-proportioning method is similar to the prior art. For details, refer to 3GPP TS 36.213, which will not be repeated here; the non-equal ratio is similar to Table 6 and Table 7.

It should be noted that the content of the above several monitoring configuration information is only an example, and any number of times that can be used to identify the blind detection on each subframe can be used as the monitoring configuration information.

The network side device 10 sends a dedicated PDCCH or EPDCCH to the user equipment 20 according to the monitoring configuration information. Correspondingly, the user equipment 20 blindly detects the PDCCH UESS or the EPDCCH UESS according to the monitoring configuration information.

After the network side device 10 determines the number of times the user equipment 20 is blindly detected on the subframe, the manner of specifically transmitting the PDCCH or EPDCCH to the user equipment 20 may be referred to the 3GPP TS 36.211 and 3GPP TS 36.213 protocols. Let me repeat.

Mode 3: The monitoring information includes monitoring position and monitoring configuration information.

The mode 3 is a combination of the mode 1 and the mode 2, that is, the PDCCH blind check configuration for multiple CCs in the second mode can be applied to only a part of the subframes, and the subframes are notified to the user equipment 20 by the method of the first method. The user equipment 20 monitors the PDCCH of the Pcell and the Scell according to the prior art, and monitors the Pcell and the Scell according to the configured PDCCH blind detection configuration division manner on another part of the subframe.

The listening position of the third mode is the same as the monitoring position of the first mode, and the monitoring configuration information of the third mode is the same as the monitoring configuration information of the second mode, and the description is not repeated here.

In the implementation, there are two ways to deal with the third method:

1. The network side device 10 determines a specific subframe frame of the user equipment in the target community according to the monitoring location, and sends a dedicated PDCCH or EPDCCH in the determined specific subframe frame according to the monitoring configuration information; correspondingly, the user equipment 20 determining, according to the monitoring location, a specific subframe set of the target community, and blindly detecting the PDCCH UESS or the EPDCCH UESS in the determined specific subframe set according to the monitoring configuration information.

In the configured specific subframe set, the user equipment 20 listens to all PDCCHs and receives the PDSCH according to the scheduling situation; in other subframes outside the specific subframe set, the user equipment 20 does not receive any downlink signals.

When the target community is a PCell, the user equipment 20 needs to correctly receive the public information (such as system information, paging message, and the like) sent by the network side device on the Pcell. Therefore, the specific subframe set of the target community includes at least the sub-information. Box 0 and subframe 5.

When the target community is an SCell, if the user equipment 20 needs to listen to public information (such as system information, paging messages, etc.) in a certain Scell, the subframe included in the specific subframe frame of the target community can make the user equipment correct. Receive public information sent by the network side device.

In an implementation, the network side device 10 does not send a downlink signal on a subframe other than the specific subframe frame; correspondingly, the user equipment 20 does not receive the subframe on a subframe other than the specific subframe frame that is needed. Downstream signal. Or the network side device 10 sends the PDCCH CSS signal on the subframe except the specific subframe set; correspondingly, the user equipment 20 does not blindly check the PDCCH UESS on the subframe other than the determined specific subframe set. Or EPDCCH UESS, only PDCCH CSS is blindly detected, and only data scheduled by DCI in the PDCCH CSS is received.

Since the user equipment 20 does not monitor or only blindly check the PDCCH CSS in a subframe other than the specific subframe set of the target community, a preferred manner is that the user equipment 20 is in a specific subframe set of the target community. In the other subframes, the blind detection capability is used for PDCCH blind detection of other communities.

Preferably, user equipment 20 may use some or all of the blind detection capabilities for PDCCH blind detection of other communities.

Preferably, the partial blind detection capability here is the ability to blindly detect the PDCCH UESS or the EPDCCH UESS.

2. The network side device 10 determines, according to the monitoring location, a specific subframe frame set of the user equipment in the target community, and sends the user equipment exclusive to the user equipment in the subframe adjacent to the specific subframe frame according to the monitoring configuration information. PDCCH or EPDCCH; correspondingly, the user equipment 20 determines a specific subframe set of the target community according to the interception location; and blindly detects the PDCCH UESS or EPDCCH UESS in a subframe other than the specific subframe set according to the interception configuration information. .
