The inventor noticed during the invention: Among the existing spectrum resources, there are some asymmetric spectrum resources, which can be used for uplink data transmission. However, they do not have corresponding spectrum resources for downlink data transmission, or these spectrum resources can be used for downlink data. Transmission, however, they do not have corresponding spectrum resources for uplink data transmission. The following uses a virtual TDD cell as an example to illustrate this type of spectrum resource.

Figure 2 is a schematic diagram of TDD and FDD frequency usage schemes with reserved protection bandwidth, one utilizing two protection bandwidths

The G1 and G2 schemes can utilize the uplink U3 and downlink D4 spectrum resources. Since the FDD band adjacent to G1 is used for uplink transmission, in order to avoid interference, only uplink U3 spectrum resources are used to transmit uplink data. By the same token, the downlink D4 spectrum resource only transmits downlink data. In order to make the uplink U3 and the downlink D4 work, a feasible solution is to form the downlink D3 and the uplink U3 into a virtual TDD cell (only the uplink U3 corresponds to the actual physical resource, and the downlink D3 is the virtual logical concept), and the uplink U4 And the downlink D4 constitutes a virtual TDD cell (only the downlink D4 corresponds to the actual physical resource, and the uplink U4 is a virtual logical concept). Both of these cells can be referred to as virtual TDD cells.

In the existing system, the UE can only work in an FDD cell or a symmetric TDD cell (that is, a TDD cell in which both uplink and downlink work on the same frequency). However, for the LTE-A (Long Term Evolution-Advanced) system, in order to improve the efficiency of TDD frequency usage, the UE may work on an asymmetric TDD cell. For example, the TDD cell has only one transmission direction. The other direction of the actual spectrum resources is virtual. That is, the spectrum resource can be used for uplink data transmission but no corresponding spectrum resource is used for downlink data transmission, or the spectrum resource can be used for uplink data transmission but no corresponding spectrum resource is used for downlink data transmission, where the correspondence can be Corresponding to the TDD mode, the spectrum resources used for uplink data transmission and the spectrum resources used for downlink data transmission are co-frequency resources and operate in different time slots.

The carrier aggregation technique will be described below.

3 is a schematic diagram of a carrier distribution of a cell in an LTE (Long Term Evolution) system. As shown in the figure, in LTE and a prior wireless communication system, there is only one carrier in a cell, and the terminal can be used in the LTE system. The maximum bandwidth is 20MHz.

In the LTE-A system, the peak rate of the system is greatly improved compared to LTE, and it is required to achieve downlink lGbps, uplink.

500Mbps. If only one carrier with a maximum bandwidth of 20 MHz is used, the peak rate requirement cannot be achieved. Therefore, the LTE-A system needs to expand the bandwidth that the terminal can use, thereby introducing a CA (Carrier Aggregation) technology, which is to aggregate multiple consecutive or discontinuous carriers under the same e B (Evolved Base Station). At the same time, it serves the UE (User Equipment) to provide the rate required for data transmission. These aggregated carriers are also referred to as component carriers (CC). The carrier used by each cell may be a component carrier, and carriers (member carriers) used by cells under different eNBs cannot be aggregated. Figure 4 shows the LTE of CA The carrier distribution diagram of the cell, as shown in the figure, in order to ensure that the UE can work under each aggregated carrier, the maximum bandwidth of each carrier does not exceed 20 MHz.

Currently, in the carrier aggregation technology of the LTE-A system, the UE can only aggregate FDD cells or symmetric TDD cells. In order to improve the efficiency of TDD frequency usage, the inventors have found that some of the asymmetric resources originally used as protection bandwidths can be utilized as virtual TDD cells. In order to avoid the interference from neighboring FDD cells, when such protection bandwidth is used as the TDD mode, there will be cases where the uplink and downlink respectively operate on different frequencies. Therefore, it is necessary to give the working mode of TDD in the above scenario.

However, there is currently no solution for how the UE works on a virtual TDD cell, in particular, only the actual physical resources exist on the uplink, and the downlink is a virtual logical concept TDD cell.

In view of this, the embodiment of the present invention proposes a logical concept TDD cell in which only the actual physical resource exists in the uplink, and the downlink is virtual, or only the physical resource in the downlink exists, and the uplink is a virtual logical concept on the TDD cell. Working Schemes Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings.

In the description process, the implementations of the UE side and the base station side will be described separately, and then the implementation of the two will be described by way of example, but this does not mean that the two must cooperate with the implementation. In fact, when the UE and the base station When implemented separately, the problems existing on the UE side and the base station side are also respectively solved, but when the two are used in combination, a better technical effect is obtained.

5 is a schematic flowchart of a method for performing processing on a spectrum resource by a base station, and may include the following steps: Step 501: A base station determines a spectrum resource to be processed, where the spectrum resource can be used for uplink data transmission, and the spectrum resource is not used. The downlink spectrum resource having the uplink-downlink correspondence is used for downlink data transmission, or the spectrum resource can be used for downlink data transmission, and the uplink spectrum resource having no uplink-downlink relationship with the spectrum resource is used for uplink data transmission; The uplink-downlink correspondence may be that the spectrum resource used for uplink data transmission and the spectrum resource used for downlink data transmission are co-frequency resources and work in different time slots.

Step 502: After determining, by the base station, that the spectrum resource needs to be utilized, notify the UE to use the carrier aggregation technology to aggregate the spectrum resource. Specifically, the UE is notified to add the spectrum resource to the carrier aggregation set, and the spectrum resource in the carrier aggregation set is aggregated by using a carrier aggregation technology, and the spectrum resource participates in the carrier set and is effectively utilized.

If the spectrum resource can be used for uplink data transmission, and the downlink spectrum resource that has no uplink-downlink relationship with the spectrum resource is used for downlink data transmission, the base station determines that the spectrum resource needs to be used for uplink data transmission. Determining that the spectrum resource needs to be utilized; if the spectrum resource can be used for downlink data transmission, and the downlink spectrum resource having the uplink-downlink relationship with the spectrum resource is used for uplink data transmission, the base station determines that the When the spectrum resource is used for downlink data transmission, it is determined that the spectrum resource needs to be utilized.

Specifically, for example, the uplink-downlink correspondence is consistent with the uplink-downlink correspondence defined by LTE Rel-8/Rel-9. In implementation, the spectrum resource may be when TDD and FDD are used for data transmission, in TDD and

Spectrum resources in the protection bandwidth between spectrum resources used by FDD.

In an implementation, the spectrum resource may be a carrier used by a secondary cell with only an uplink carrier, or may be an extended carrier or a carrier segment (segment). among them:

The secondary cell is a carrier that is used by the UE and has one or more secondary cells. The primary cell has a PUCCH (Physical Uplink Control Channel) and can perform radio link detection. Random access and provision of NAS (Non-Access Stratum, non-access stratum) mobility information. The secondary cell does not have the above functions, but is used as an additional resource. Both the primary cell and the secondary cell are backward compatible (compatible with LTE Rel-8/Rel-9).

Extended carrier: carrier resources different from the carrier used by the primary cell and the secondary cell, not backward compatible, may be

Terminal aggregation for Rel-11 and later.

Carrier segment: A carrier resource that is different from the carrier used by the primary cell and the secondary cell and the extended carrier. Generally, the bandwidth is narrow and cannot work independently. It may be aggregated by terminals in Rel-11 and later versions.

In an implementation, the base station may notify the UE to aggregate the spectrum resource by using RRC (Radio Resource Control) signaling.

In an implementation, the base station may also notify the UE of one or any combination of the following parameters through RRC signaling:

The uplink configuration parameter of the spectrum resource, the cross-carrier scheduling parameter of the spectrum resource, the downlink configuration parameter of the spectrum resource, and the common configuration parameter of the spectrum resource.

In an implementation, the base station may further indicate that the path loss reference and the timing reference of the spectrum resource of the UE are: a path loss reference and a timing reference of the reference cell explicitly configured by the RRC signaling; or are in the same band (band) as the spectrum resource. a path loss reference and timing reference of other cells outside the cell to which the spectrum resource belongs; or a path loss reference and timing reference of the primary cell; or a path loss reference and timing reference of the cell scheduling the spectrum resource.

Specifically, the path loss reference and the timing reference of the virtual cell to which the spectrum resource belongs may be a reference cell explicitly configured by RRC signaling, or another cell in the same band, or a primary cell, or a cell scheduling the spectrum resource. Road loss reference and timing reference.

In an implementation, the base station may separately activate or deactivate the spectrum resource by using a MAC CE (MAC: Media Access Control, CE: Control Element, Control Unit).

Specifically, the base station may separately activate and deactivate the virtual cell to which the spectrum resource belongs by using the MAC CE.

In the implementation, the spectrum resource can be used for uplink data transmission, and the downlink spectrum resource that has no uplink-downlink relationship with the spectrum resource is used for downlink data transmission, and the base station can also perform carrier tube according to the uplink signal of the spectrum resource. Reason. When the spectrum resource can be used for downlink data transmission, and the downlink spectrum resource that has no uplink-downlink relationship with the spectrum resource is used for uplink data transmission, the base station performs carrier management according to the downlink signal of the spectrum resource.

Specifically, the base station may perform carrier management according to the uplink signal of the virtual cell to which the spectrum resource belongs, that is, perform carrier scheduling, deactivation, and release according to the uplink signal shield, and the uplink signal includes an SRS (Sounding Reference Symbol), PUSCH (Physical Uplink Shared Channel).

In an implementation, the method further includes: configuring, by the base station, the related parameter of the spectrum resource for the UE, where the base station initially uses the full configuration mode when configuring the relevant parameter of the spectrum resource for the UE, and then needs to modify the relevant parameter, and then use the full configuration or The incremental configuration mode updates the related parameters of the configuration.

Specifically, the base station may use a full configuration when initially adding the virtual cell to the UE, and subsequent modification of the virtual cell parameter may use a full configuration or an incremental configuration.

In an implementation, when the spectrum resource can be used for uplink data transmission, and the downlink spectrum resource that has no uplink-downlink relationship with the spectrum resource is used for downlink data transmission, the base station may not configure A1 or A2 or A6 for the spectrum resource. Measure events.

Specifically, the network does not configure an A1/A2/A6 measurement event for the virtual cell to which the spectrum resource belongs, and the UE does not perform measurement in the downlink subframe position of the virtual cell.

In an implementation, the base station may also schedule UEs across carriers to use the spectrum resources.

FIG. 6 is a schematic flowchart of a method for performing processing on a spectrum resource by a UE, and may include the following steps: Step 601: A UE receives a notification of a base station, and acquires a spectrum resource indicated in the notification, where the spectrum resource can be used for uplink data transmission. And the downlink spectrum resource that has no uplink-downlink relationship with the spectrum resource is used for downlink data transmission, or the spectrum resource can be used for downlink data transmission, and there is no uplink with uplink/downlink relationship with the spectrum resource. Spectrum resources are used for uplink data transmission;

Step 602: The UE aggregates the spectrum resource by using a carrier aggregation technology according to the notification. Specifically, the UE adds the spectrum resource to the carrier aggregation set according to the notification, and aggregates the spectrum resource in the carrier aggregation set by using a carrier aggregation technology.

In an implementation, the spectrum resource may be a spectrum resource in a protection bandwidth between a TDD and an FDD spectrum resource when data transmission is performed by using the TDD and FDD modes.

In implementation, the notification may be notified by the base station by using RRC signaling.

In an implementation, the UE may also use the carrier aggregation technology to aggregate the spectrum resource according to one or any combination of the following parameters that the base station notifies the UE through RRC signaling:

The uplink configuration parameter of the spectrum resource, the cross-carrier scheduling parameter of the spectrum resource, and the downlink configuration of the spectrum resource Parameters, common configuration parameters of the spectrum resource.

In an implementation, the UE may also be scheduled across carriers to use the spectrum resource.

In the implementation, when the acquired spectrum resource can be used for uplink data transmission, and the downlink spectrum resource that has no uplink-downlink relationship with the spectrum resource is used for downlink data transmission, the UE may also include the spectrum in determining the RRC signaling. When the TDD configuration parameter of the resource and/or the MBSFN (Multicast Broadcast Single Frequency Network) subframe configuration parameter, the UE uses the reference cell explicitly configured by the RRC signaling, or is in the same band as the spectrum resource. The parameters of the other cells except the cell to which the spectrum resource belongs, or the primary cell, or the cell that schedules the spectrum resource are used as the TDD configuration parameter and/or the MBSFN subframe configuration parameter of the spectrum resource.

In the implementation, the UE may further allocate the reference cell that is explicitly configured by the RRC signaling, or other cells outside the cell to which the spectrum resource belongs, or the primary cell, or schedule the spectrum, according to the indication of the base station. The path loss reference and timing reference of the resource cell are used as the path loss reference and timing reference of the spectrum resource.

Specifically, the path loss reference and the timing reference of the virtual cell to which the spectrum resource belongs may be a reference cell that is explicitly configured by the RRC signaling, or another cell except the cell to which the spectrum resource belongs in the same band as the spectrum resource. Or the primary cell, or the path loss reference and timing reference of the cell that schedules the virtual cell.

In an implementation, the UE may also separately activate or deactivate the spectrum resource according to the received MAC CE.

In the implementation, the UE may also not detect the PDCCH (physical downlink control channel) of the spectrum resource in the downlink subframe position of the spectrum resource; or may not accept the downlink scheduling; or ignore the received downlink scheduling signal. make.

Specifically, the acquired spectrum resource can be used for uplink data transmission, and when the downlink spectrum resource that has the uplink-downlink relationship with the spectrum resource is used for downlink data transmission, the UE is in the downlink subframe of the virtual cell to which the spectrum resource belongs. The location does not detect the PDCCH of the local cell, does not accept the downlink scheduling (does not receive the PDSCH of the local cell); if the downlink scheduling signaling is received, the UE actively ignores. When the acquired spectrum resource can be used for downlink data transmission, and the downlink spectrum resource that has no uplink-downlink relationship with the spectrum resource is used for uplink data transmission, the UE does not accept uplink scheduling in the uplink subframe position of the spectrum resource. Or ignore the received uplink scheduling signaling.

In the implementation, the obtained spectrum resource can be used for uplink data transmission, and when the downlink spectrum resource that has the uplink-downlink relationship with the spectrum resource is used for downlink data transmission, the UE can also be in the downlink subframe position of the spectrum resource. No measurement is taken. The acquired spectrum resource can be used for downlink data transmission, and the downlink spectrum resource that has no uplink-downlink relationship with the spectrum resource is used for uplink data transmission, and the UE does not perform measurement on the uplink subframe position of the acquired spectrum resource.

Specifically, the acquired spectrum resource can be used for uplink data transmission, and has no uplink/downlink corresponding to the spectrum resource. When the downlink spectrum resource of the system is used for downlink data transmission, the network does not configure the virtual cell to which the spectrum resource belongs.

The A1/A2/A6 measurement event, the UE does not measure at the downlink subframe position of the cell.

In an implementation, the UE may also perform radio link monitoring on a downlink subframe position of the spectrum resource.

Specifically, the acquired spectrum resource can be used for uplink data transmission, and when the downlink spectrum resource that has the uplink-downlink relationship with the spectrum resource is used for downlink data transmission, the UE is in the downlink subframe of the virtual cell to which the spectrum resource belongs. Location, no wireless link monitoring. When the acquired spectrum resource can be used for downlink data transmission, and the downlink spectrum resource that has no uplink-downlink relationship with the spectrum resource is used for uplink data transmission, the UE does not perform the wireless chain on the uplink subframe position of the acquired spectrum resource. Road monitoring.

In an implementation, the base station notifies the UE of one of the following parameters or a combination thereof by using RRC signaling: an uplink configuration parameter of the spectrum resource, a cross-carrier scheduling parameter of the spectrum resource, a downlink configuration parameter of the spectrum resource, and a common configuration parameter of the spectrum resource. .

And, when the UE aggregates the spectrum resource by using a carrier aggregation technology according to one of the foregoing parameters of the UE or the combination of the foregoing parameters, the UE may be as follows:

The base station may include, in the RRC signaling, an uplink configuration parameter of the virtual cell to which the spectrum resource belongs, a center frequency of the uplink carrier, a bandwidth, a maximum allowed uplink transmit power, an uplink CP (Cyclic Prefix), and a power control. Related parameters, antenna-related parameters, PUSCH transmission-related parameters, SRS transmission-related parameters, etc.; the base station may include cross-carrier scheduling parameters of the virtual cell to which the spectrum resource belongs in the RRC signaling, such as scheduling other cells of the virtual cell. Cell index;

The base station may include, in the RRC signaling, a downlink configuration parameter of the virtual cell to which the spectrum resource belongs, such as a cell index, a cell identifier (a frequency point, and a physical cell identity (PCI));

The eNB may include common configuration parameters of the virtual cell to which the spectrum resource belongs, such as TDD configuration (including subframe configuration and special subframe configuration), MBSFN subframe configuration, and the like.

In the above solution, except for the special mention of the TDD cell, the other is also applicable to the one-way, only the uplink virtual FDD cell, only the uplink secondary cell (including TDD and FDD), the extended carrier, the carrier segment, and the separate uplink. FDD carrier.

The following is an example.

Example 1

This embodiment will introduce an implementation of an aggregate uplink TDD virtual cell. The network scenario is shown in Figure 2:

There are two adjacent TDD cells, Cell 1 and Cell 2. The spectrum resources used by Cell 1 are adjacent to the uplink spectrum resources of the FDD cell, and there is a protection bandwidth G1 between the two, and the spectrum resources used by the cell 2 and the downlink spectrum of the FDD cell. The resources are adjacent, and there is a protection bandwidth G2 between the two. In order to improve spectrum utilization, an uplink U3 is introduced in G1. The virtual TDD cell, in G2, introduces a virtual TDD cell with only downlink D4.

The UE is currently working on the cell 1 and the cell 2, and the cell 1 is the primary cell. Because the uplink traffic increases, the network decides to add the aggregated carrier to the UE, that is, the UE aggregates U3. At this time, the network combines U3 and D3 into a virtual TDD cell, and then informs the UE of the uplink, downlink, cross-carrier scheduling, and common configuration information of the virtual TDD cell by using RRC dedicated signaling, because the virtual TDD cell is initially added. The relevant parameters in the RRC signaling can be used in a fully configured manner. The uplink configuration parameter includes a center frequency of the uplink carrier of the virtual TDD cell, a bandwidth, a maximum allowed uplink transmit power, an uplink CP length, a power control related parameter, an antenna related parameter, a PUSCH/SRS transmission related parameter, and the like; The parameters include a cell index of the virtual TDD cell, a cell identifier (frequency point and PCI), and the like; the cross-carrier scheduling parameter includes a cell index of another cell that schedules the virtual TDD cell; the common configuration parameter includes a TDD configuration of the virtual TDD cell (including a sub- Frame configuration and special subframe configuration), MBSFN subframe configuration, etc.

The UE receives the RRC signaling, adds the virtual TDD cell (U3) to the carrier aggregation set, and then performs configuration using parameters in the RRC signaling. The base station then activates the UE to operate on the cell through the MAC CE. The base station allocates the path loss reference and the timing reference of the virtual TDD cell to the cell 1, and the UE works on the virtual TDD cell according to the reference information of the cell 1. The base station configures the virtual TDD cell as a cross-carrier scheduling, and the cell that schedules it is the cell 1. The UE monitors the PDCCH of the cell 1 during operation, accepts the uplink scheduling signaling scheduled by the U3, and performs uplink data transmission on the U3. In addition, the base station configures the SRS and schedules the PUSCH data to obtain the uplink channel shield information of the U3, and performs carrier management on the cell (U3). If the SRS channel of U3 is poor, the base station can deactivate the virtual cell through the MAC CE or release the virtual cell through RRC signaling. When the UE works on the virtual TDD cell (U3), the PDCCH of the local cell is not detected, and the downlink scheduling is not accepted (the PDSCH of the local cell is not received) in the downlink subframe position of the cell, if the downlink scheduling signaling is received. Then, the UE actively ignores, and the UE does not perform measurement (including RSRP, RSRQ, etc.), and does not perform radio link monitoring.

Example 2

This embodiment will describe the implementation of an aggregated downlink TDD virtual cell. The network scenario is the same as in Embodiment 1:

The UE currently works on the cell 1 and the cell 2. As the downlink traffic increases, the network decides to add an aggregated carrier to the UE, that is, the UE aggregates D4. At this time, the network forms D4 and U4 into a virtual TDD cell, and then reports the downlink, cross-carrier scheduling, and common configuration information of the cell to the UE through RRC dedicated signaling. The downlink configuration parameter includes a cell index of the virtual TDD cell, a cell identifier (frequency point and PCI), and the like; the cross-carrier scheduling parameter includes a cell index of another cell that schedules the virtual TDD cell; and the common configuration parameter includes a TDD configuration of the virtual TDD cell. (including subframe configuration and special subframe configuration), MBSFN subframe configuration, and so on.

The UE receives the RRC signaling, adds the virtual TDD cell (D4) to the carrier aggregation set, and then configures using parameters in the RRC signaling. The base station then activates the UE to work on the virtual TDD cell through the MAC CE. Base The station configures the path loss reference and the timing reference of the virtual TDD cell on the cell itself. Base station by configuring RRM

(Radio Resource Management, Radio Resource Management) measurement and CQI (Channel Quality Indicator) reporting, obtaining downlink channel shield information of D4, and performing carrier management on the cell (D4). If the measurement result of D4 indicates that the downlink channel shield is poor, the base station may activate the virtual cell by using the MAC CE, or release the virtual cell by using RRC signaling. The UE does not accept the uplink scheduling of the cell. If the uplink scheduling signaling is received, the UE actively ignores, and does not perform uplink signal transmission such as PUSCH, CQI feedback, and SRS in the uplink subframe position of the cell.

Based on the same inventive concept, a base station and a user equipment are also provided in the embodiment of the present invention. Since the principle of solving the problem is similar to the method for processing the spectrum resource, the implementation of the device may refer to the implementation of the method. The repetitions are not repeated here.
