The present invention relates to the field of wireless communications, and in particular, to a resource configuration method, apparatus, and system. Background technique

Peer-to-Peer communication, or D2D (Device-to-Device) proximity service is a form of more direct interaction and communication between user equipment. Without the support of a network-side infrastructure, D2D is more like an ad hoc (peer-to-peer) network. If there is network side support, such as D2D integration into the cellular communication network, then at least the following benefits and applications:

1. D2D discovery can serve services of neighboring user equipment. This feature of neighboring user equipment can serve multiple commercial application levels.

2. The D2D communication can be used when the neighboring user equipment has communication requirements. This communication method can increase the system throughput, reduce the power consumption of the user equipment, and perform traffic offloading from the eNodeB (base station) side;

3. Use D2D as a relay (relay) technology to enhance cell coverage.

On the other hand, in order to improve the cell coverage and user experience in the LTE-A (long term evaluation advanced) system, and improve the throughput of the system and the data transmission rate of the user, a plurality of small cell (small cell) dense deployment scenarios, And the transmission/reception technology compatible with it will be introduced. This technology can enhance the coverage of the network, improve the reuse rate of resources and system throughput, and control the total energy consumption of the access network based on a certain network capacity.

By using a low-power node such as a Pico eNodeB (micro base station), an emote radio head (a remote radio head), and a home eNodeB (home base station), a small cell can be deployed according to the operator's needs and the regional characteristics of the service. ) Π small cell cluster (small cell cluster). In order to adapt the air interface and access network technologies to this channel condition and environmental characteristics, some new functions and features will be introduced.

In the current LTE TDD (Time Division Duplexing) system, the user's uplink and downlink resources are divided in the time domain by means of time division duplexing, and there are seven different configurations. Compared with FDD (Frequency Division Duplexing), this duplex mode provides another dimension of resource allocation optimization, which can adapt to the actual uplink and downlink traffic load ratio. However, in the small cell scenario, for dual The TDD configuration of the user equipment of the connectivity (dual connectivity) feature is a problem that needs to be addressed. For example, the uplink and downlink transmission points and reception points respectively correspond to different cells (cells, also referred to as base stations). In this case, if the TDD configurations of the two connectivity networks are different, the user equipment (UE, User Equipment, also called TDD configuration for the terminal or user) can be a problem. In addition, even if the two connectivity networks are FDD or one is FDD and the other is TDD, the TDD configuration of the terminal is still a problem that needs to be studied and considered in particular, especially for efficient resource configuration and avoiding system errors. time.

The foregoing and other features of the embodiments of the invention will be apparent from the These embodiments are merely exemplary and are not limiting of the invention. The embodiments of the present invention are described by taking the resource configuration in the D2D communication in the LTE-A system as an example, but it can be understood that the embodiment of the present invention is used to enable a person skilled in the art to easily understand the principles and embodiments of the present invention. It is not limited to the above system, and is applicable to other systems and other point-to-point communication methods involving resource allocation in point-to-point communication.

In the process of implementing the present invention, the inventors have found that in the scenario of D2D communication, resources for D2D discovery and resources for D2D communication need to be considered. Regardless of whether the network coverage is TDD or FDD, how to select "downstream" and "uplink" subframes/resources for D2D discovery and communication is one of the problems to be solved in the industry.

In the embodiment of the present invention, the user's "uplink" subframe/resource refers to the user's transmission subframe or resource unless otherwise specified; the user's "downlink" subframe/resource refers to the user's receiving subframe or Resources.

Example 1

The embodiment of the invention provides a resource configuration method for peer-to-peer communication. Figure 1 is a flow chart of the method. Referring to Figure 1, the method includes:

Step 101: The base station sends resource configuration information to the D2D user, where the resource configuration information indicates the

D2D users are used for transmitting and receiving resources for D2D discovery and/or communication.

In this embodiment, the base station notifies the D2D user in the D2D communication of the resource configured for the D2D discovery or communication by using the resource configuration information, and indicates, by using the resource configuration information, the sending resource and the receiving required by the D2D user. Resources. Thus, the D2D user can use the base station to transmit data for its configured transmission resources, and use the base station to receive data for its configured receiving resources, thereby improving resource utilization and avoiding system errors.

The resources allocated to the D2D user (including the foregoing sending resource and the receiving resource) may be a TDD resource or an FDD resource, depending on the type of the cellular network in which the D2D user is located.

If the resource allocated to the D2D user is a TDD resource, the resource configuration information may be configured by TDD. The way of combining the directions indicates that the TDD configuration may be consistent with the TDD configuration of the cellular network, or may be inconsistent.

When the TDD configuration of the D2D user and the TDD configuration of the cellular network are consistent, the direction indicates the relationship between the D2D user's transmission and reception and the uplink and downlink of the cellular network, for example, "same direction" indicates that the uplink corresponding D2D user of the cellular network is sent. The downlink of the cellular network corresponds to the reception of the D2D user; the "reverse" indicates that the uplink of the cellular network corresponds to the reception of the D2D user, and the downlink of the cellular network corresponds to the transmission of the D2D user. At this time, the resources allocated to the D2D user are the resources of the cellular network (including the uplink resource and the downlink resource), and the correspondence between the D2D user's transmission and reception and the uplink and downlink of the cellular network is indicated by the "direction", so the D2D user's The uplink and downlink of the transceiver and the cellular network will not cause interference.

2 is a schematic diagram of a specific implementation manner. As shown in FIG. 2, the base station configures a TDD configuration for a certain/some D2D pair, or a certain/some D2D link, or a certain/some D2D session (session). #0 (DSUUUDSUUU), the direction under this configuration is up and down, up and down, where "down" represents the downlink of the cellular network, and "up" represents the uplink of the cellular network. In the example of FIG. 2, in the direction indicated by TDD configuration #0, UE#1 is configured with a transmission subframe of 0, 1, 5, 6, and the receiving subframe is 2, 3, 4, 7, 8, 9; The corresponding UE#2 is configured with a transmission subframe of 2, 3, 4, 7, 8, 9, and the received subframes are 0, 1, 5, and 6. Therefore, the base station configures the TDD configuration #0 for the D2D user through the high layer signaling, and configures the correspondence between the sending and receiving directions and the TDD configuration #0 for the D2D user through the 1-bit dedicated signaling (UE-specific). Or reverse), thereby completing the configuration of D2D resources (transmission resources and reception resources for D2D discovery and D2D communication).

When the TDD configuration of the D2D user is inconsistent with the TDD configuration of the cellular network, the direction is also indicated by the direction.

The relationship between the D2D user's sending and receiving and the uplink and downlink of the cellular network. At this time, the resource allocated to the D2D user is a subset of the uplink resource or the low-load downlink resource of the cellular network, and the resource configuration information includes a subframe set in addition to the TDD configuration and the direction bound to the TDD configuration. Since uplink resources or low-load downlink resources that have little impact on the transmission of the cellular network are used as D2D resources, there is no significant interference to the transmission of the cellular network during D2D discovery or communication. The low-load downlink resource refers to a downlink resource with a relatively low load, for example, an ABS subframe. In this embodiment, the downlink resource of the low load is not limited. In an implementation manner, the resource occupancy rate may be lower. A resource with a preset threshold is used as a low-load resource, and may also be a low-load resource defined by other definitions, for example, a resource containing only certain specific reference signals, and the like.

Figure 3 shows the TDD configuration of the cellular network as TDD configurations, and the TDD configuration configured for D2D users. The transmission and reception diagram of TDD configuration #0 is set. As shown in FIG. 3, when the downlink subframes 4 and 9 of the cellular network are used as the ABS, the load is relatively small. At this time, although this part of the resources is the downlink resource of the cellular network, It may also be assigned to the D2D user as its transmission resource or reception resource. In this example, the transmission resource and the reception resource allocated to the D2D UE#1 are a subset of the subframes 2, 3, 4, 7, 8, 9 The transmission resource and the reception resource allocated to the D2D UE#2 are also a subset of the subframes 2, 3, 4, 7, 8, and 9. The subframes 2, 3, 7, and 8 are uplink resources of the cellular network, and the subframes 4 and 9 are low-load downlink resources of the cellular network.

4 is a schematic diagram of the TDD configuration of the cellular network as TDD configuration #0, and the TDD configuration configured for the D2D user is TDD configuration #1, as shown in FIG. 4, in this example, the transmission resource allocated to the D2D UE#1 And the receiving resource is a subset of the subframes 2, 3, 4, 7, 8, 9 . Similarly, the transmitting resource and the receiving resource allocated to the D2D UE #2 are also subframes 2, 3, 4, 7, 8, 9 a subset of. Among them, subframes 2, 3, 4, 7, 8, and 9 are uplink resources of the cellular network.

In an embodiment of the present embodiment, the resource configuration information may be carried by a high layer signaling, such as broadcast signaling or dedicated signaling. As described above, it may include a TDD configuration used by the D2D user (TDD configuration 0). Any one of ~6) and/or a set of subframes, and a direction indication indicating a correspondence between transmission and reception of the configured resources and transmission and reception of the TDD configuration and/or the subframe set . For example, "codirectional" means that the direction of transmission and reception of the configured resources is consistent with the direction of transmission and reception of the TDD configuration and/or the subframe set, that is, corresponding to the TDD configuration and/or An uplink/transmission resource of the subframe set, where the configured resource is a transmission resource, corresponding to the TDD configuration and/or the downlink/reception resource of the subframe set, where the configured resource is a receiving resource; otherwise, “reverse "The direction indicating the transmission and reception of the configured resources is inconsistent with the direction of the TDD configuration and/or the transmission and reception of the subframe set (opposite).

In another embodiment of the present embodiment, the resource configuration information is also carried by the high layer signaling, which is different from the previous embodiment in that the resource configuration information includes a TDD configuration and/or a sub-user that can be used by the D2D user. A set of frames, and various combinations of direction indications; and specifically which one is used by the D2D user, and is additionally indicated by configuration indication information. In this embodiment, in addition to sending the resource configuration information to the D2D user, the base station sends configuration indication information to the D2D user, where the configuration indication information indicates which TDD configuration the D2D user uses and/or Subset set, and direction indication. The configuration indication information may be carried by the control signaling of the physical layer, for example, DCI (Downlink Control Information), but this embodiment is not limited thereto. The meaning of the direction indication is the same as the foregoing, and details are not described herein again. In this embodiment, preferably, when the cellular network does not use the ABS, the TDD configuration used by the UE has some fixed combination restrictions. If the TDD configuration of the cellular network is TDD configuration #0, the TDD configuration that the UE can use includes TDD configuration^ or 2 or 3 or 4 or 5 or 6; if the TDD configuration of the cellular network is TDD configuration^, the UE can The TDD configuration used includes TDD configuration #2 or 3 or 4 or 5; if the TDD configuration of the cellular network is TDD configuration #2, the TDD configuration that the UE can use includes TDD configuration #3 or 4 or 5; if the TDD of the cellular network The configuration is TDD configuration #3, and the TDD configuration that the UE can use includes TDD configuration #1 or 2 or 4 or 5; if the TDD configuration of the cellular network is TDD configuration #4, the TDD configuration that the UE can use includes TDD configuration# 2 or 5; If the TDD configuration of the cellular network is TDD configuration #6, the TDD configuration that the UE can use includes TDD configuration^ or 2 or 3 or 4 or 5.

If the resource allocated to the D2D user is a TDD resource, in addition to configuring the D2D user resource by using the TDD configuration binding direction (or further combining the subframe set) as described above, the D2D user may be directly configured by using the subframe set directly. Resources, at this time, the resource configuration information may directly indicate which subframes the D2D user uses as the transmission subframe (transmission resource), and which subframes are used as the reception subframe (reception resource). Therefore, the configuration of the D2D resource can also be realized by the direct configuration. In the manner of directly configuring the sending resource and the receiving resource, the sending resource and the receiving resource may be a subset of the uplink resources of the cellular network.

If the resource allocated to the D2D user is an FDD resource, the physical resource block (PRB) set used as the transmission resource and the PRB set used as the receiving resource allocated to the D2D user may be directly indicated by the foregoing resource configuration information, or may be adopted. The resource configuration information indicates an available frequency band used as a transmission resource and a reception resource allocated to the D2D user, and the allocation of the available frequency band may be divided from an uplink spectrum resource used by the D2D user's cellular network.

In order to indicate which of the frequency bands allocated to the D2D user are the transmission resources and which are the receiving resources, the base station may also send configuration indication information to the D2D user to indicate which of the frequency bands of the D2D user are used as the transmission resources, and which are Receive resources. The configuration indication information may also be carried by the control signaling of the physical layer, but the embodiment is not limited thereto.

Wherein, if the resources allocated by the base station to the D2D user are separated from the time slot spectrum resources of the cellular network The frequency band, the D2D user can work in either the FDD mode or the TDD mode. At this time, the base station may further send the working mode indication information to the D2D user to indicate whether the specific working mode of the D2D user is FDD or TDD. The working mode indication information may be carried by the high-layer signaling bearer or the control signaling of the physical layer. This embodiment is not limited thereto.

Optionally, if the resource allocated by the base station to the D2D user is a frequency band divided by the time slot spectrum resource of the cellular network, the D2D user may also work according to a default working mode, such as a TDD mode. The base station does not need to send the above working mode indication information to the D2D user.

The method of the embodiment of the present invention configures a sending resource and a receiving resource for a D2D user (a D2D user of a D2D pair, or a D2D user of a D2D link, or a D2D user of a D2D session), thereby improving resource utilization and avoiding system errors.

Example 2

The embodiment of the present invention further provides a resource configuration method, and FIG. 5 is a flowchart of the method. Referring to FIG. 5, the method includes:

Step 501: The base station sends resource configuration information to the user in the dual connectivity state, where the resource configuration information indicates the sending resource of the user in the dual connectivity state.

The dual connectivity state may be a state of TDD-FDD inter-operation (TDD-FDD inter-operation) or a state of TDD-FDD carrier aggregation (TDD-FDD Carrier Aggregation), which is not limited by this embodiment. .

In this embodiment, the configuration method of the transmission resource is the same as the configuration method of the D2D resource in the first embodiment, and the content thereof is incorporated herein, and details are not described herein again. For example, if the cell initiated by the scheduling is the working mode of the TDD, the resource configuration information may include a TDD configuration and/or a subframe set used by the user, and a direction; and may also include a TDD configuration and/or a subframe set available to the user. And various combinations of directions; it is also possible to directly indicate which subframes are used as transmission resources. If the cell initiated by the scheduling is an operating mode of the FDD, the resource configuration information may include a frequency band allocated to the user, where the frequency band is allocated from an uplink spectrum resource used by the cellular network, and may also directly indicate which PRB sets are used as the mode. Launch resources, and more.

The method of the embodiment further includes: if the resource configuration information includes a TDD configuration and/or a subframe set available to the user, and a plurality of combinations of directions, the method in this embodiment further includes:

The base station device sends configuration indication information to the user, indicating which one of the multiple combinations is used by the user as its own configuration. The method of the embodiment further includes: if the resource configuration information includes an available frequency band that is configured for the user,

The base station device sends the working mode indication information to the user, indicating whether the user works in the FDD mode or the TDD mode.

Optionally, if the resource configuration information includes an available frequency band configured for the user, the base station may not send the working mode indication information to the user, and the user works according to its default working mode.

6 is a schematic diagram of a special scenario of the embodiment. As shown in FIG. 6, a user is in a dual-connected state, that is, more than one base station serves it. If one of the connections is in the TDD mode, the other connection is It is the working mode of FDD, and the user is a half-duplex UE, the user cannot send and receive data at the same time. In this case, if the downlink sub-frame user receives the UL grant (upstream grant) in DCI format 0 (DCI format 0) or transmits the PHICH (Physical HA Q Indicator Channel, physical HARQ (in this sub-frame) Hybrid Automatic Repeat Request, Hybrid Automatic Repeat Request, then UL (uplink) transmission in n+k subframes, where the value of k is based on the scheduling. The cell (cell) is a TDD of TDD or TDD. Configuration varies. Then in the n+k subframe, the user cannot listen to the DL (downlink) subframe, nor can it receive the data or control signaling of the DL subframe transmission. In this way, some downlink subframes, such as SIB-x (System Information Block), aging (ppipping), MBSFN (Multicast Broadcast Single Frequency Network), etc., may be missed. This problem can be avoided by configuring the user with its transmission resources by the method of the embodiment of the present invention.

The specific scenario shown in FIG. 6 is only an example. This embodiment is not limited to this. In other scenarios where the uplink resource (sending resource) needs to be configured for the dual-connected user, the method in this embodiment may also be used. .

The method of the embodiment of the present invention configures a transmission resource for a user in a dual connection state, thereby avoiding a system error.
