The resulting impact leads to lower communication efficiency.

Specifically, "alignment" refers to the determination of the carrier frequency for sending and receiving the interaction message, the determination of the type of the interaction message, the meaning of the field information carried in the interaction message, or the The understanding of other configurations of interactive messages is consistent.

In addition, in other possible cases, the network device may be other devices that provide wireless communication functions for the terminal device.

For convenience of description, the embodiments of the present application are not limited.

In the technical solutions provided by the embodiments of the present application, the technical solutions provided by the embodiments of the present application are described by taking the device for realizing the function of the network device being a network device as an example.

(3) The terms "system" and "network" in the embodiments of the present application may be used interchangeably. "At least one" means one or more, and "plurality" means two or more. "And/or", which describes the association relationship of the associated objects, means that there can be three kinds of relationships, for example, A and/or B, which can mean: the existence of A alone, the existence of A and B at the same time, and the existence of B alone, where A, B can be singular or plural. The character "/" generally indicates that the associated objects are an "or" relationship.

For example "at least one of A, B and C" includes A, B, C, AB, AC, BC or ABC. And, unless otherwise specified, ordinal numbers such as “first” and “second” mentioned in the embodiments of the present application are used to distinguish multiple objects, and are not used to limit the order, sequence, priority or importance of multiple objects degree.

The present application can be applied to a long term evolution (long term evolution, LTE) system, a new radio (new radio, NR) system, or other communication systems, wherein the communication system includes network equipment and terminal equipment, and the network equipment is used as a configuration The information sending entity, and the terminal device acts as the configuration information receiving entity. Specifically, an entity in the communication system sends configuration information to another entity, and sends data to another entity, or receives data sent by another entity; another entity receives the configuration information, and sends the configuration information to the configuration information according to the configuration information. The entity sends data, or receives data sent by the configuration information sending entity. Wherein, the present application can be applied to a terminal device in a connected state or an active state (ACTIVE), and can also be applied to a terminal device in a non-connected state (INACTIVE) or an idle state (IDLE).

As shown in Figure 1-1, the configuration information sending entity may be a network device. The network device is described by taking a base station (Base Station) as an example, and the configuration information receiving entities may be UE1-UE6. In this case, the base station and UE1-UE6 A communication system is formed. In the communication system, UE1-UE6 can send uplink data to network equipment, and the network equipment needs to receive the uplink data sent by UE1-UE6. At the same time, the network device may send configuration information to UE1-UE6.

In addition, in Figure 1-1, UE4-UE6 can also form a communication system. At this time, both the configuration information sending entity and the receiving entity can be UEs, wherein UE5 acts as a network device, that is, the configuration information sending entity; UE4 and UE6 As a terminal device, that is, a configuration information receiving entity. For example, in a car networking system, UE5 sends configuration information to UE4 and UE6 respectively, and receives uplink data sent by UE4 and UE6; correspondingly, UE4 and UE6 receive configuration information sent by UE5 and send uplink data to UE5.

Taking the scenario shown in Figure 1-1 as an example, the communication system can be applied to indoor scenarios for enterprise customers (to business, to B or 2B). Among them, 2B is mainly for smart manufacturing, smart hospitals, smart exchanges, smart warehousing, etc. Industry application scenarios help enterprises effectively accelerate the construction of enterprise intelligence and facilitate the digital transformation of the industry. Different from traditional consumer-oriented (to customer, to C or 2C) applications, it is mainly based on large uplink and low-latency applications. In open and large-level scenarios such as intelligent manufacturing, large uplink capacity requires cell splitting to improve Regional capacity. However, cell splitting inevitably introduces cell edge problems, that is, inter-cell interference on the same frequency leads to low signal quality, and user throughput and delay cannot be guaranteed.

Exemplarily, simulation results for a project are provided as follows:

1) The downlink simulation conditions are set as shown in Table 1.

Table 1

As shown in Figure 1-2 and Figure 1-3, the simulation results show that the SINR of 10.8% of the regions is less than 5dB.

2) In addition, through modeling, as shown in Figure 1-4, the uplink estimation is performed, and the simulation results are shown in Table 2.

Table 2

Through the estimation, it can be found that the SINR value of the user in the center of the cell (pRRU edge) is -0.61dB. This is because the uplink interference is essentially different from the downlink interference, and the downlink interference is only in the geographical area of the cell edge (users in this area are interfered), The uplink interference affects all users under the interfered pRRU. The near-point users of the pRRU interfere less, and the far-point users interfere more.

3) A low SINR value will also cause the delay to fail to meet business requirements.

table 3

Among them, as shown in Table 3, if the required delay meets 40ms@99.99% (wherein, 40ms represents the delay, 99.99% represents the probability, that is, 99.99% of the probability delays are all ≤40ms), then the SINR value needs to reach 26dB.

4) As shown in Figure 1-5, it is a traditional multi-carrier network and a cell split scenario. In the figure, the 2.6G and 4.9G dual-band network is used as an example. The 2.6G and 4.9G frequency bands are deployed at the same location indoors. A cell consists of 8 pRRUs.

Among them, the cell splitting boundaries of different carriers are the same, and the simulation results are shown in Table 4. In this way, it is easy to lead to poor edge SINR values.

In view of the above problems, this application proposes a multi-carrier heterogeneous solution to solve the edge interference after cell splitting. The general idea is to cover two layers of carriers with staggered coverage. As shown in Figure 1-6, the cell edge users of carrier 1 are connected to the cell center of carrier 2. , the cell edge users of carrier 2 move to the cell center of carrier 1 to increase the uplink/downlink SINR value.

At present, the data transmitted in the 2C application scenario is generally a small packet service, and the time-frequency resources of the data can be staggered to a large extent. Generally, carrier aggregation can be used to introduce discontinuous carrier frequency bands into the communication system. According to the transmission characteristics of the home base station layer, micro base station layer and macro base station layer and the characteristics of different carrier frequency bands, the carrier and transmission power can be selected through interference measurement. Allocating spectrum resources in a way to reduce the impact of cell edge problems.

Exemplarily, the processes involved in the implementation of carrier aggregation are described below.

(1) Carrier aggregation: Introduce discontinuous carrier frequency bands to heterogeneous networks, and heterogeneous networks allocate spectrum resources according to the transmission characteristics of the home base station layer, micro base station layer and macro base station layer and the characteristics of different carrier frequency bands;

(2) Interference coordination at the home base station layer: The home base station selects a carrier frequency band as the communication frequency band according to its own transmission characteristics. At the same time, each home user measures its own signal-to-interference and noise ratio and compares it with the set threshold. Adjust the transmit power of the home base station until the home base station communicates normally in the selected carrier frequency band;

(3) Interference coordination at the micro base station layer: The micro base stations are clustered according to the distances between all the micro base stations, and carrier frequency band resources are allocated to all the micro base stations according to the clustering results; the micro base stations occupy multiple carrier frequency bands at the same time, and the At the same time, the micro-user measures its own received signal strength and received signal-to-noise ratio, compares the test result with the threshold, and adjusts the occupied carrier frequency band according to the comparison result;

(4) Interference coordination at the macro base station layer: The macro base station transmits signals with different powers on different carrier frequency bands. At the same time, the macro user measures its own received signal strength and received signal-to-noise ratio on different carrier frequency bands, and compares them with the set threshold. The comparison is performed, and the carrier frequency band is allocated according to the comparison result.

Among them, the interference coordination method based on carrier aggregation minimizes the interference between stations in the entire heterogeneous network through the allocation of carriers and the control of transmit power. However, this scheme is actually based on coordinated scheduling between base stations. In terms of time-frequency resources, the time-frequency resources with the lowest interference are selected to complete data scheduling, but this scheme is more suitable for small-packet service scenarios (time-frequency resources can be staggered to a large extent) , In scenarios such as 2B smart factories, where there is a fullbuffer service, and there is a high probability of collision of time-frequency resources, it is difficult to avoid interference by selecting a carrier and transmit power scheme through interference measurement in the prior art. That is to say, the data transmitted in the 2B application scenario includes continuous large-packet (fullbuffer) services, which will occupy all the time-frequency resources. The time-frequency resources of the data are difficult to stagger, and it is difficult to avoid the cell edge by using carrier aggregation. The impact of the problem results in lower communication efficiency.

To this end, the embodiments of the present application provide a communication device and method, which are used to reduce the influence of the cell edge problem caused by the carrier edge and improve the communication efficiency.

Please refer to FIG. 2 , which is a schematic diagram of a communication device according to an embodiment of the present application.

As shown in FIG. 2 , the communication device includes a first transceiver; wherein the first transceiver is used to transmit and receive a first carrier and a second carrier, wherein the carrier frequency band of the first carrier is the same as the second carrier. The carrier frequency bands of the carriers do not overlap, the signal coverage of the first carrier includes the first carrier center (12) and the first carrier edge (11, 13), and the signal coverage of the second carrier includes the second carrier center (22) and a second carrier edge (21, 23), and the first carrier edge and the second carrier center have a first overlapping area, and the second carrier edge and the first carrier center have a second overlapping area.

Optionally, the signal coverage of the first carrier (or the second carrier) may be represented by a triangular area as shown in FIG. 2 , and may also be represented by a circle, a rectangle, a sector, or other regular or irregular areas, here Not limited. It can be understood that, in the embodiments of the present application, the signal coverage is only implemented as a triangular area for description as an example of implementation.

In a possible implementation manner, the first carrier includes a first subcarrier, and the second carrier includes a second subcarrier, wherein the phase of the first subcarrier is different from the phase of the second subcarrier.

In a possible implementation manner, the first carrier further includes a third subcarrier, the second carrier further includes a fourth subcarrier, wherein the phase difference between the first subcarrier and the third subcarrier is different is the phase difference between the second sub-carrier and the fourth sub-carrier.

In a possible implementation manner, the first transceiver includes a first signal transceiving surface for transceiving the first carrier, and a second signal transceiving surface for transceiving the second carrier; the first signal transceiving surface The angle value of the included angle between the signal sending and receiving direction of the second signal sending and receiving surface and the signal sending and receiving direction of the second signal sending and receiving surface is less than 180°.

In a possible implementation manner, the communication device may be a micro remote radio unit pRRU.

Based on the communication device shown in FIG. 2 , an embodiment of the present application further provides a communication system. As shown in FIG. 3 , the communication system includes an adjacent communication device, and the communication shown in the first aspect and any implementation manner thereof. device; wherein, the adjacent communication device includes a second transceiver, the second transceiver is used to send and receive a third carrier, the signal coverage of the third carrier includes the center of the third carrier and the edge of the third carrier, and the third carrier A third overlapping area exists between the center and the edge of the second carrier, and a fourth overlapping area exists between the center of the second carrier and the edge of the third carrier.

Based on the above technical solution, the device using the carrier edge communication of the second carrier in the third overlapping area can communicate through the carrier center of the third carrier, and the device using the carrier edge communication of the third carrier in the fourth overlapping area can communicate through the third carrier. The carrier center of the two carriers communicates. That is, in the communication system, the cooperation between the communication device and the adjacent communication device shown in the first aspect and any implementation manner thereof can reduce the influence of the cell edge problem caused by the edge of the carrier wave in the carrier heterogeneous scenario, and improve the communication. efficiency.

In a possible implementation manner, the adjacent communication device may be a micro remote radio unit pRRU.

The following is an exemplary description by taking the network device as a pRRU, the frequency band where the first carrier is located is 2.6G, and the frequency band where the second carrier is located is 4.9G as an example. The implementation of carrier heterogeneity is shown in Figure 4, in which the same antenna is used for different carriers to cover different areas, and then the edges of different carriers are complementary to "eliminate" the cell edge.

As shown in Figure 5, by modeling the pRRU spacing is 10m, the antenna height is 4m. Based on a 65-degree-wavewidth antenna, using link estimation, the SINR value gain after carrier staggered coverage is analyzed, and the measurement results of the simulation implementation shown in Figure 6 are obtained.

According to the data shown in Figure 6, we can get:

1) Before the antenna rotates 30°, the co-frequency cell attenuates 65.1+10=75.1dB at the midpoint (5m) of the pRRU, so the SINR value at the midpoint is 0dB.

2) Assuming that the 2.6G pRRU antenna patterns are all rotated to the right by 30°, then the pRRU signal on the left at the midpoint of the pRRU (5m) is attenuated by 65.1+2.34=67.44dB, and the right pRRU signal is attenuated by 65.1+22.69=87.79dB.

Then the SINR value at the midpoint=(-67.44)-(-87.79)=20.35dB.

That is to say, after rotating by 30°, the SINR value is improved by 20.35dB. The main source of gain here is the difference in attenuation between the narrow beam main lobe and side lobes (since the distance does not change, the path loss value is the same).

Based on the embodiments shown in Figures 4-6, two technologies for implementing carrier heterogeneous antenna feeds are provided below.

As shown in FIG. 7 , it is a schematic diagram of the implementation of the carrier heterogeneous antenna. Specifically, it includes two sets of feeder networks: 2.6G and 4.9G; dual-band (2.6G&4.9G) controls the beam direction through dual reflectors; the reflectors of the two frequency bands are offset from left to right by a certain angle (for example, 30 degrees relative to the center line) etc.); the antenna width is expected to be 300mm, and the thickness is expected to be 150mm. The schematic diagram of the radiation effect achieved is shown in Figure 8. The advantages of the solutions shown in Figures 7 and 8 include:

1) The antenna beam offset is realized by the transmitting plate, not by shaping, which reduces the requirement for the number of antenna elements and reduces the size of the antenna;

2) There is no need to add additional power dividers, bridges and other devices inside the antenna, and the power consumption is low.

As shown in FIG. 9 and FIG. 10 , it is a schematic diagram of the implementation of the carrier heterogeneous antenna. Specifically, it includes: the antenna is divided into left and right structures; the left and right are 2T2R, forming a composite pattern; supporting 4T4R, the length is expected to be 600mm, and the specific implementation parameters are shown in Table 5.

通道2幅度 Channel 2 Amplitude	11	11

It forms an effect similar to the antenna pattern shown in Figure 11 below. You can get:

1. In the scenario of common antennas in different frequency bands, carrier heterogeneity is realized;

2. The SINR value of the cell split edge point is greatly improved.

In this embodiment, through the embodiments shown in FIG. 2 to FIG. 11 , carrier heterogeneity is implemented by hardware, which reduces cell edge interference, rather than based on interference coordination between intra-frequency cells; in addition, split intra-frequency cells It is possible to achieve complete time-frequency resource multiplexing between them, instead of the existing cooperative multiplexing of resources, which improves the spectral efficiency.

Please refer to FIG. 12 , which is a schematic diagram of a communication method according to an embodiment of the present application. The method includes the following steps.

In a possible implementation manner, the first channel quality information includes reference signal received power RSRP.

In a possible implementation manner, the carrier frequency band of the first network device is the same as the carrier frequency band of the second network device.

In a possible implementation manner, the first network device may be a remote micro radio unit pRRU, and/or the second network device may be a remote micro radio unit pRRU.

S102. The first network device adjusts the signal transceiving power according to the first channel quality information.

In this embodiment, the first network device adjusts the signal transceiving power according to the first channel quality information received in step S101.

In a possible implementation manner, the first network device adjusting the signal transceiving power according to the first channel quality information in step S102 includes: when the first channel quality information is lower than a first threshold, the first network device Improve signal transmission and reception power.

In a possible implementation manner, the first network device adjusting the signal transceiving power according to the first channel quality information in step S102 includes: when the first channel quality information is higher than a second threshold, the first network device Reduce signal transmission and reception power.

In a possible implementation manner, the first network device adjusting the signal transceiving power according to the first channel quality information in step S102 includes: the first network device adjusting according to the first channel quality information and the second channel quality information Signal transceiving power, wherein the second channel quality information is used to indicate the channel quality of the terminal device accessing the first network device.

In a possible implementation manner, the first network device adjusting the signal transceiving power according to the first information in step S102 includes: when the service attribute of the transmission data of the terminal device satisfies a preset condition, the first network device The signal transceiving power is adjusted according to the first information.

In a possible implementation manner, the second channel quality information includes reference signal received power RSRP.

In this embodiment, the first network device adjusts the signal transmission and reception of the first network device according to the first channel quality information that is fed back by the second network device and used to indicate the channel quality of the terminal device accessing the second network device. Based on the power, through this adjustment process, the time-frequency resources used by the terminal equipment accessing the first network device or the second network device can be staggered to a certain extent, softening the edge of cell splitting, making different networks The load balancing optimization of the serving cell provided by the device reduces the impact of the cell edge problem caused by the carrier edge and improves the communication efficiency.

Exemplarily, FIG. 13 is a schematic diagram of a network in which the communication method shown in FIG. 12 is implemented, and the first network device and the second network device are both pRRUs as an example for description. Wherein, based on the pRRU-level power adjustment capability between the first network device and the second network device, breathing coordination between cells in the same frequency is achieved, and flexible adjustment of heterogeneous areas is realized. Its key realization process includes at least the following steps.

1) Identification of user business needs: classification based on 5QI, and only special identification for users with high capacity and low latency;

2) User location identification: Based on the RSRP difference between the serving cell and the same-frequency neighboring cell, if it is less than 3dB, it is judged to be on the edge;

Table 6

Specifically as shown in Table 6, considering the fluctuation of the signal, the RSRP is filtered, and 5 filter sample points are recommended.

3) Identification of key TRPs: A terminal that meets the requirements of 1 and 2 at the same time identifies its serving cell and neighboring cell TRPs; specifically, for distributed MM cells, in multiple TRP scenarios, the primary serving cell is identified by uplink receiving the strongest RSRP TRP of , and TRP of neighboring cells.

4) SINR value evaluation: The basic principle is to improve the SINR value of edge high-capacity & low-latency users, and the SLA of other users can be satisfied (over-guaranteed users can be allowed to drop).

Evaluate whether the SINR value of users with high capacity and low latency at the edge increases after adjusting the power, and whether the SINR value of other users with high capacity and low latency in the center of the cell decreases, such as whether the decrease can meet the SLA.

In this embodiment, through the implementation process of the communication method shown in FIG. 12 to FIG. 13 , the edge of cell splitting is softened (for example, 10% coverage expansion and contraction), so as to optimize load balancing among cells; in addition, in the scenario of uneven traffic distribution , improve the UE SLA guarantee, and the UE SINR near the cell split boundary is improved by an average of 5dB.

Based on the aforementioned communication processes shown in FIGS. 2 to 13 , reference may be made to FIG. 14 for an example of a carrier heterogeneous scenario that can be constructed. In FIG. 14 , the elliptical regions with the same grayscale represent the coverage of the same carrier frequency band, and the elliptical regions with different grayscales represent the coverage of different carrier frequency bands. Through the aforementioned process of increasing the SINR value and load balancing, the processes shown in the example of "Carrier Concatenation", "Hybrid Splitting", and "Inter-frequency Flower Arrangement" as shown in Figure 14 can be realized. Obviously, in different carrier heterogeneous scenarios , there may also be other implementation processes, which are not specifically limited here.

Please refer to FIG. 15 , which is a schematic diagram of a communication method according to an embodiment of the present application. The method includes the following steps.

S201. The terminal device determines at least two SSB SINRs one-to-one corresponding to the at least two carriers from the network device.

S202. The terminal device determines, in the at least two carriers, a target carrier for communication with the network device based on the at least two SSB SINRs.

In a possible implementation manner, in step S202, the terminal device determines the target carrier to communicate with the network device based on the at least two SSB SINRs in the at least two carriers includes: the terminal device is in the at least two In the SSB SINR, determine at least one carrier corresponding to the SSB SINR whose SSB SINR value is greater than the first threshold; the terminal device determines the target carrier in the at least one carrier.

Optionally, the terminal device is in a resident state.

Based on the above technical solutions, the terminal device can determine at least one carrier in combination with the preset first threshold, and further determine the target carrier through the at least one carrier, so that the SSB SINR of the target carrier determined by the terminal device meets certain requirements, and also A specific implementation of determining the target carrier is provided.

In a possible implementation manner, in step S202, the terminal device determines the target carrier to communicate with the network device based on the at least two SSB SINRs in the at least two carriers includes: the terminal device is in the at least two Among the SSB SINRs, it is determined that the first carrier corresponding to the SSB SINR with the largest SSB SINR value is the target carrier.

Optionally, the terminal device is in an access state.

Based on the above technical solution, the terminal device can determine the first carrier corresponding to the SSB SINR with the largest SSB SINR value among the at least two SSBs as the target carrier, so that the SSB SINR of the target carrier determined by the terminal device is the largest, improving communication While improving the efficiency, it also provides a specific implementation method for determining the target carrier.

In a possible implementation manner, in step S202, the terminal device has accessed the second carrier, and the terminal device determines the target carrier to communicate with the network device in the at least two carriers based on the at least two SSB SINRs The method includes: when the SSB SINR value of the second carrier is less than a second threshold, the terminal device determines, in the at least two carriers, a target carrier to communicate with the network device based on the at least two SSB SINRs.

Optionally, the terminal device is in a connected state.

In a possible implementation manner, in step S202, when the SSB SINR value of the second carrier is less than the second threshold, the terminal device determines the communication with the network based on the at least two SSB SINRs in the at least two carriers The target carrier for device communication includes: when the SSB SINR value of the second carrier is less than the second threshold, and the difference between the SSB SINR value and the SSB SINR value of the second carrier exists in the at least two SSB SINRs is greater than the third threshold. , the terminal device determines a target carrier for communication with the network device in the at least two carriers based on the at least two SSB SINRs.

In this embodiment, the terminal device can perform carrier layering based on the SSB-SINR values corresponding to multiple carriers, so that the terminal device can select a target carrier based on the SSB-SINR in a carrier heterogeneous scenario, and further based on the target carrier and the network Communication between devices does not require manual configuration, improving the efficiency of heterogeneous deployment.

Further, in the communication process shown in FIG. 2 to FIG. 14 , how to switch the terminal device to a carrier with a better SINR value and avoid frequent switching leading to poor throughput is also a technical problem that needs to be solved. Specifically, consider the following: Since the CSI SINR value is affected by the load, it is not conducive to judging the SINR value of the UE at the edge of the cell, so the SSB SINR value is used; in addition, it depends on all cells to configure the same SSB location; since the SSB-SINR value cannot reflect the load In this case, load imbalance may be caused, so carrier load balancing measures are required; SINR value improvement and load balancing cannot lead to frequent ping-pong switching, which will affect the throughput rate.

The communication process shown in FIG. 15 will be described below through a specific example.

When the terminal device is in the parked state:

1) Cell selection: random camping;

2) Cell reselection: reselection initiated based on the SSB SINR value threshold;

When the terminal device is in the access state:

1) Select the carrier based on the SSB SINR measurement;

When the terminal device is connected:

1) If SSB SINR value (serving cell)≤X dB, X can be configured, and the default selection is 20dB;

2) The compression model measures the SSB SINR value of the inter-frequency carrier (neighboring cell);

3) If SSB SINR value (neighboring cell) - SSB SINR value (serving cell) ≥ Y dB, Y can be configured, and 3 dB is selected by default;

4) If the condition 3) is satisfied, switch to the neighboring cell, otherwise keep in the serving cell;

5) In order to avoid the negative impact of frequent lamination: the user does not switch to another carrier after lamination, and penalizes it. The time is t hours, t can be configured, and the default configuration is 1; ii After switching, it also enters the lamination cooling time;

6) The load balancing algorithm uses the formula (5QI Num)/(spectrum bandwidth * timeslot ratio * spectrum efficiency) to control the bearer carrier of the large packet/low delay user. Spectral efficiency=bit/RE, in this formula, the numerator is the number of users, and the denominator is the product of bandwidth, time slot, and spectral efficiency. That is, which frequency band has a larger bandwidth and higher spectral efficiency, it will carry more users.

In this embodiment, through the embodiments shown in Figures 2 to 15, the SINR value of users at the uplink/downlink edge (downlink cell edge, uplink pRRU edge) can be improved, the SLA of edge users can be guaranteed, and the overall capacity of the cell can be improved; On the other hand, based on the head-end power adjustment, the heterogeneous boundary is flexibly controlled, and the SINR value of edge high-capacity/low-latency users is improved; in addition, based on the SSB-SINR value The UE carrier layering can realize the automatic selection of the best carrier by the UE without manual configuration, and improve the efficiency of heterogeneous deployment.
