Background technique

Indoor visible light communication (VLC) uses the high-speed flashing of light-emitting diode (LED) lights to transmit information, using free space as the transmission channel. It is a new high-speed and environmentally friendly indoor access network technology. Since the light emitted by LED lights as a light source has a certain directionality, its coverage area is small. When the user moves to an area not covered by VLC, the service will be interrupted; on the other hand, compared to the penetrability of wireless communication ,VLC is easily affected by obstructions, causing ,interruption of communication links. In addition, considering that visible light uplink is difficult to implement in practical applications, VLC can be combined with other wireless access methods for heterogeneous networking.

Detailed ways

The present disclosure will be described in further detail below with reference to the accompanying drawings and embodiments.

In the heterogeneous network shown in Figure 1, as shown in Figure 2, after the terminal is turned on, it first accesses the radio frequency base station through a series of processes such as synchronization and random access through the radio frequency uplink and downlink, so that the terminal Enter the radio frequency connection state; then, the radio frequency base station configures the candidate visible light base station for the terminal, and the terminal measures the synchronization signal quality of the candidate visible light base station, and reports the measurement results to the radio frequency base station through the radio frequency uplink. The radio frequency base station selects the visible light base station with the best quality and re- Configuration is added; finally, the visible light base station sends data to the terminal, and the terminal provides feedback through the radio frequency uplink. Among them, considering that there is no visible light uplink in the heterogeneous networking system, the terminal communicates directly with the visible light base station and does not need to perform uplink synchronization through the random access process.

Among them, in the above process, considering that the radio frequency base station operates in a high-frequency band (such as above 6GHz), during the initial access of the radio frequency, as shown in Figures 3a and 3b, coarse pairing of beams can be achieved through the random access process. As a result, a beam pairing with relatively good link quality can be established between the terminal and the radio frequency base station to support subsequent data transmission. Since it is a coarse pairing, the corresponding transmit beam and receive beam will be relatively wide, that is, the coverage range is relatively large. Therefore, better performance can be obtained by using the formed beam pairing, but the formed beam pair is not an optimal pairing. At the same time, during the initial radio access process or after the terminal enters the radio connection state, the radio base station can configure candidates for the terminal through radio downlink. Visible light base station; specifically, the terminal measures the synchronization signal of the candidate visible light base station and sends the measurement results to the radio frequency base station through the coarsely paired uplink beam. The radio frequency base station configures an appropriate visible light base station for the terminal according to the measurement results reported by the terminal for visible light downlink transmission. . In order to further improve performance, it is necessary to fine-tune the network's transceiver beams based on coarse beam pairing. Here, considering that after the terminal establishes the Radio Resource Control (RRC) connection of radio frequency and visible light, in order to save energy, the radio frequency downlink is closed, and all control channels and data channels are transmitted through the visible light downlink, so only It is necessary to finely adjust the network uplink receiving beam and the terminal uplink transmitting beam. As shown in Figure 4, it is assumed that the terminal has two uplink narrow beams, namely: beam A and beam B, and the network has three uplink reception beams, namely: beam 1, beam 2 and beam 3.

In related technology, with reference to Figure 5, the process of radio frequency uplink beam scanning includes:

First, the network configures 2 channel sounding reference signals (Sounding Reference Signal, SRS) resources for the terminal. The terminal uses 2 consecutive time slots as a cycle and uses beams A and B respectively to send these 2 SRS in the first cycle. resources, the network receives the two SRS signals in sequence through beam 1, performs measurements, and determines which narrow beam has better performance;

Then, in the next cycle, that is, in the second cycle, the terminal still uses beams A and B to send the two SRS resources respectively. The network switches to beam 2 to receive the two SRS signals in sequence, perform measurements, and determine which one sends the narrow beam. Better performance;

Then, in the third cycle, the terminal still uses beams A and B to send the two SRS resources respectively. The network switches to beam 3 to receive the two SRS signals in sequence, perform measurements, and based on the reception results of these three cycles, Select the best pair of receive and transmit beams.

As can be seen from the above process, assuming that the terminal has J (J is an integer greater than or equal to 2) transmitting beams and the network side has K (K is an integer greater than or equal to 2) receiving beams, a total of J× needs to be measured K beam pairs can be used to find the best transmitting and receiving paired beams. Correspondingly, for the terminal, J×K SRS resources need to be sent, which will result in large energy consumption of the terminal. Therefore, in the architecture of visible light communication heterogeneous networking, whether the information of visible light base stations can be used to reduce the number of uplink beam transmissions by the terminal, thereby reducing energy consumption, is an issue that needs to be considered.

Based on this, in various embodiments of the present disclosure, the terminal determines the first access mode according to the association between the reference signal resources for the first mode and the reference signal resources for the second mode indicated by the network side. The set of uplink receiving beams.

The solution provided by the embodiments of the present disclosure can establish the relationship between the first access network device that provides access in the first mode and the second access network device that provides access in the second mode through the association relationship between the indicated reference signal resources. The corresponding relationship between the beams is determined to determine the uplink receiving beam set of the first method. In this way, the terminal does not need to send multiple reference signal resources for each receiving beam on the network side, thereby reducing the uplink requirements of the terminal on the basis of realizing beam management. The number of beam transmissions reduces the energy consumption of the terminal.

Embodiments of the present disclosure provide a beam management method, which is applied to terminals. As shown in Figure 6, the method includes:

Step 601: Receive first information indicating the association between a first reference signal resource and a second reference signal resource. The first reference signal resource is used for the first access network device. The second reference signal resource indicates the association between the first reference signal resource and the second reference signal resource. The signal resource is used for a second access network device. The first access network device can provide the terminal with access in the first mode, and the second access network device can provide the terminal with access in the second mode. Access, the first method is different from the second method;

Step 602: Use the first information to determine the uplink receiving beam set.

Wherein, in actual application, the terminal may be called user equipment (User Equipment, UE), terminal equipment, equipment, or user, etc. Access network equipment can be called base stations, etc.

The first access network device and the second access network device form a heterogeneous network. The first access network device may be called a Master Node (MN), and correspondingly, the second access network device may also be called a Secondary Node (SN).

In an embodiment, the first mode of access includes radio frequency access.

In an embodiment, the access in the second mode includes optical communication access, which may specifically be VLC access (which may also be called visible light access). That is to say, the first access network device can provide The terminal provides radio frequency access, and the second access network device can provide VLC access to the terminal; accordingly, the first access network device may include a radio frequency access point (Access Point, AP) ( also may (called a radio frequency base station), the second access network device includes an RLC AP (also called a visible light base station).

Wherein, the terminal may receive data and control information sent by the first access network device through a radio frequency downlink. Correspondingly, the terminal may send data and/or feedback information of the data (ie, Hybrid Automatic Repeat ReQuest (HARQ)-Acknowledgement (ACK) information) through the radio frequency uplink. At this time, the terminal is in a heterogeneous network composed of VLC and radio frequency. In this heterogeneous network, heterogeneous networking refers to: VLC downlink (also called visible light downlink) and radio frequency uplink. Radio frequency downlink can be turned on on demand.

In practical application, in step 601, the terminal receives first information sent by the first access network device and/or the second access network device. Exemplarily, the terminal receives a system message sent by the first access network device and/or the second access network device, and the system message includes the first information, that is, the system message indicates the first The association relationship between a reference signal resource and a second reference signal resource.

In the embodiment of the present disclosure, when the downlink from the first access network device to the terminal is closed, that is, when the downlink between the first access network device and the terminal is not used to send any signals and/or channels, the The first reference signal resource may be called a virtual reference signal resource. It can be understood that the virtual reference signal resource is transmitted through the downlink virtual transmission beam in the first manner; correspondingly, the second reference signal resource is transmitted through the downlink virtual transmission beam in the second manner. Therefore, it can be understood that the correlation relationship may indicate that the coverage range of the downlink beam in the second manner is within the coverage range of the downlink virtual transmission beam in the first manner.

In actual application, the terminal may receive the second reference signal resource sent by at least one second access network device. Wherein, when the terminal receives the second reference signal resource sent by a second access network device, the terminal is connected to a second access network device, and the terminal is in a single connection state at this time; when the terminal When receiving second reference signal resources sent by at least two second access network devices, the terminal is connected to at least two second access network devices. At this time, the terminal is in a multi-connection state (including dual connection and multi-connection). ).

In step 602, the terminal may determine an uplink reception beam corresponding to the transmission beam of the first reference signal resource based on the received second reference signal resource and the first information.

In the embodiment of the present disclosure, the uplink receiving beam and virtual downlink transmitting beam of the first access network device The correspondence of the beams is established. In actual application, the first access network device is used for the downlink transmission beam of the terminal (i.e., the virtual downlink transmission beam) and the first access network device is used for the downlink transmission of the second access network device. The beams can be the same or different.

When the downlink transmission beam used by the first access network device for the terminal is the same as the downlink transmission beam used by the first access network device for the second access network device, the first information indicates The association relationship may include an association relationship between the first reference signal resource and the second reference signal resource.

Wherein, this association relationship may include uniform association or non-uniform association. Here, the uniform correlation is applicable to the situation where each second reference signal resource corresponds to one first reference signal resource. Correspondingly, the non-uniform correlation is applicable to the situation where each visible light second reference signal resource corresponds to multiple first reference signal resources.

In an embodiment, when the association relationship includes uniform association, the first information includes the number M of first reference signal resources and the number N of second reference signal resources;

The terminal associates the first A first reference signal resources among the M first reference signal resources with B second reference signal resources among the N second reference signal resources, and associates the first A first reference signal resources among the M first reference signal resources with B second reference signal resources among the N second reference signal resources. The last MA first reference signal resources are respectively associated with C second reference signal resources among the N second reference signal resources to obtain the first association information; where, A=mod(N,M), mod(·) represents the remainder function, means rounding up, Indicates rounding down, M and N are both integers greater than 1;

The terminal determines an uplink reception beam set using the received at least one second reference signal resource and the first association information.

Wherein, all first reference signal resources (i.e., M first reference signals) and second reference signal resources (i.e., N second reference signal resources) are configured for the terminal in advance. Therefore, the terminal uses the The first information can obtain the IDs of all the first reference signal resources and the second reference signal resources, that is, the terminal obtains the corresponding sorting results. The terminal performs association in sequence according to the sorting result of the first reference signal resource and the sorting result of the second reference signal resource.

For example, assume that M is 3, which are the first reference signal resources 1, 2, and 3 respectively, and N is 6. They are the second reference signal resources 1, 2, 3, 4, 5, and 6, respectively. As shown in Figure 7a, the terminal associates the first reference signal resource 1 with the second reference signal resources 1 and 2, associates the first reference signal resource 2 with the second reference signal resources 3 and 4, and associates the first reference signal resource 1 with the second reference signal resource 3 and 4. Resource 3 is associated with second reference signal resources 5 and 6.

For example, assume that M is 3, which are the first reference signal resources 1, 2, and 3 respectively, and N is 7, which are the second reference signal resources 1, 2, 3, 4, 5, 6, and 7 respectively. As shown in Figure 7b, the terminal associates the first reference signal resource 1 with the second reference signal resources 1, 2 and 3, associates the first reference signal resource 2 with the second reference signal resources 4 and 5, and associates the first reference signal resource 2 with the second reference signal resources 4 and 5. Reference signal resource 3 is associated with second reference signal resources 6 and 7.

When the association relationship includes non-uniform association or uniform association, the association relationship may be referred to by a bitmap.

Based on this, in one embodiment, the association between the first reference signal resource and the second reference signal resource is represented by a bitmap;

The terminal uses the received at least one second reference signal resource and bitmap to determine an uplink receiving beam set.

For example, assume that M is 3, which are the first reference signal resources 1, 2, and 3 respectively, and N is 6, which are the second reference signal resources 1, 2, 3, 4, 5, and 6 respectively. As shown in Figure 8a, the second reference signal resource 1 is associated with the first reference signal resource 1, and the corresponding bitmap indication is 100. The second reference signal resource 2 is associated with the first reference signal resource 2, and the corresponding bitmap indication is 100. 010, the second reference signal resource 3 is associated with the first reference signal resource 2, and the corresponding bitmap indication is 010, and so on; as shown in Figure 8b, the second reference signal resource 1 is associated with the first reference signal resources 1 and 2 associated, the corresponding bitmap indicates 110. The first information needs to indicate bitmaps corresponding to all second reference signal resources within the coverage range.

The received at least one second reference signal resource can be understood as the received at least one second reference signal.

In actual application, you can choose one of the above indication methods according to your needs.

When the first access network device is used for the downlink transmission beam of the terminal and the first access network When the downlink transmission beams used by the device for the second access network device are different, the association indicated by the first information includes: the association between the first reference signal resource, the second reference signal resource and the third reference signal resource. In the relationship, the third reference signal resource is used for the first access network device, and the third reference signal resource is used for the downlink transmission wave of the second access network device through the first access network device. Beam transmission (that is, the first access network device sends a third reference signal resource to the second access network device through a downlink transmission beam), and there is a QCL relationship between the first reference signal resource and the third reference signal resource.

Wherein, there is a QCL relationship between the first reference signal resource and the third reference signal resource, which means that the first reference signal resource and the third reference signal resource have the same or similar channel characteristics.

Here, this association relationship is uniformly related or non-uniformly related. Here, the uniform correlation is applicable to the case where each second reference signal resource corresponds to a third reference signal resource. Correspondingly, the non-uniform correlation is applicable to the situation where each visible light second reference signal resource corresponds to multiple third reference signal resources.

In an embodiment, the first information includes the number M of first reference signal resources, the number N of second reference signal resources, and the number P of third reference signal resources;

The terminal associates the first D third reference signal resources among the P third reference signal resources with the E second reference signal resources among the N second reference signal resources, and associates the P third reference signal resources with the last one. PD third reference signal resources are respectively associated with F second reference signal resources among N second reference signal resources to obtain second association information; where, D=mod(N,P), P and N are both integers greater than 1;

The terminal associates the first G first reference signal resources among the M first reference signal resources with the H third reference signal resources among the P third reference signal resources, and associates the first G first reference signal resources among the M first reference signal resources with The last MG first reference signal resources are respectively associated with I second reference signal resources among the P second reference signal resources to obtain third association information; where, G=mod(P,M), M is an integer greater than 1;

The terminal uses the received at least one second reference signal resource and the second association information and the third association information to determine an uplink reception beam set.

Wherein, all first reference signal resources (ie, M first reference signals), second reference signal resources (ie, N second reference signal resources), and third reference signal resources (ie, P third reference signal resources), therefore, the terminal can learn the IDs of all the first reference signal resources, the second reference signal resources and the third reference signal resources according to the first information, that is, the terminal learns the corresponding ranking result. The terminal performs association in order according to the sorting result of the first reference signal resource, the sorting result of the second reference signal resource and the sorting result of the third reference signal resource.

For example, assume that M is 2, which are the first reference signal resources 1 and 2 respectively, N is 8, which are the second reference signal resources 1, 2, 3, 4, 5, 6, 7 and 8 respectively, and P is 4 , are the third reference signal resources 1, 2, 3, and 4 respectively. As shown in Figure 9a, the terminal associates the third reference signal resource 1 with the second reference signal resources 1 and 2, associates the third reference signal resource 2 with the second reference signal resources 3 and 4, and associates the third reference signal resource 1 with the second reference signal resource 1 and 2.

A reference signal resource 2 is associated with third reference signal resources 3 and 4.

For example, assume that M is 2, which are the first reference signal resources 1 and 2 respectively, N is 7, which are the second reference signal resources 1, 2, 3, 4, 5, 6, and 7 respectively, and P is 3, respectively. are third reference signal resources 1, 2, and 3.

Reference signal resource 3 is associated with second reference signal resources 6 and 7; first reference signal resource 1 is associated with third reference signal resources 1 and 2, and first reference signal resource 2 is associated with third reference signal resource 3.

Based on this, in one embodiment, the association between the first reference signal resource, the second reference signal resource and the third reference signal resource is reflected by a bitmap;

As shown in Figure 10, the third reference signal resource associated with each second reference signal resource is indicated by a bitmap. Specifically, the second reference signal resource 1 is associated with the third reference signal resource 1, and the corresponding bitmap indication is 1000, the second reference signal resource 2 is associated with the third reference signal resource 1, and the corresponding bitmap indication is 1000. The second reference signal resource 3 is associated with the third reference signal resource 2, and the corresponding bitmap indication is 0100.

Specifically, the third reference signal resource 1 is associated with the first reference signal resource 1, and the corresponding bitmap indication is 10, and the third reference signal resource is indicated by a bitmap. Reference signal resource 2 is associated with the first reference signal resource 1, the corresponding bitmap indication is 10, the third reference signal resource 3 is associated with the first reference signal resource 2, the corresponding bitmap indication is 01, and the third reference signal resource 4 Associated with the first reference signal resource 2, the corresponding bitmap indication is 01. The first information needs to indicate the bitmaps corresponding to all second reference signal resources within the coverage range, and the bitmaps corresponding to all third reference signal resources.

After determining the uplink receiving beam set, the terminal can perform uplink beam scanning based on the determined uplink receiving beam set to find the optimal receiving and transmitting beam pair. Among them, since the uplink reception beam set is determined, when the terminal performs beam scanning, it only needs to send reference signal resources to the uplink reception beams in the uplink reception beam set, and does not need to send reference signal resources to all the uplink reception beams in the first access network device. The uplink receiving beam transmits reference signal resources. Assume that the terminal has O uplink transmitting beams, the first access network device has Q uplink receiving beams, and the determined uplink receiving beam set contains Q' uplink receiving beams, and Q' is less than Q , then the terminal needs to measure a total of O×Q' beam pairs, that is, the The terminal only needs to send O×Q' reference signal resources. In this way, the number of transmissions of the terminal's uplink beam is greatly reduced, thereby reducing energy consumption.

Wherein, the terminal needs to know the uplink transmission beam.

Based on this, in an embodiment, the method may further include:

Specifically, the terminal determines the uplink channel or the uplink transmission beam used for uplink signal transmission based on the source signal contained in the spatial relationship information.

In actual application, the second information may be sent by the first access network device or may be sent by the second access network device. The source signal may be an SRS signal, and the network side may indicate the uplink transmission beam used for uplink transmission by indicating the SRS Resource ID (SRI).

The corresponding relationship between the beams is determined to determine the uplink receiving beam set of the first method. In this way, the terminal does not need to send multiple reference signal resources for each receiving beam on the network side, but only sends for the receiving beams in the uplink receiving beam set. Reference signal resources are used to reduce the number of uplink beam transmissions by the terminal on the basis of beam management, thereby reducing the energy consumption of the terminal.
