Description

Resource allocation method, resource determination method, resource allocation device, network side equipment and terminal
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a resource allocation method, a resource determination device, a network side device, and a terminal.
Background
In a terrestrial mobile communication system, based on the principle of cellular communication, frequency resources of different cells are reused, and the frequency reuse factor of a cell is generally 1. The ground communication has complex propagation environment, more shelters, larger attenuation, larger difference between the cell center and cell boundary signal strength, generally 10-20dB difference, the base station mainly determines that the user belongs to the cell center user or the cell boundary user based on the CQI (Channel Quality Indication) feedback of the terminal, and the base station generally performs data scheduling by using a lower level MCS (Modulation and Coding Scheme) for the cell boundary user. Further, interference avoidance of cell edge users can be realized by a Coordinated Multiple Points (CoMP) technology between base stations.
In a satellite communication system, the satellite communication system has a great difference with ground communication, the first difference is that the transmission distance is far, the link budget is worse than that of the ground communication, and even at the center point of a cell beam, the signal-to-noise ratio is usually below 10dB, which causes poor tolerance of the satellite communication to interference; the second difference is that the signal transformation is slow in the cell, mainly because the satellite signal is usually a direct path, the distance from the satellite to the ground is much greater than the radius of the cell, especially for a high orbit satellite, the difference between the cell center and the cell edge is small, which makes it difficult to reduce the inter-cell interference through the natural attenuation of the signal, and it is difficult to judge whether the terminal is a cell boundary user or a cell center user through the received signal strength of the terminal; for the above two reasons, the resource allocation of the existing satellite communication is mainly based on FDM (Frequency-division multiplexing), different beams or different cells use different Frequency band resources, and the interference between cells can be obviously suppressed by using the FDM method, but the Frequency spectrum utilization rate is low, which is not beneficial to providing the service of a large-scale user. Typical FDM schemes include the use of 4-color multiplexing, 6-color multiplexing, and even 8-color multiplexing, which undoubtedly increases the consumption of frequency resources, and presents significant challenges to the deployment and operation of satellite networks.
However, when the satellite communication system is used to provide broadband internet services, the required frequency band resources are large, and if the FDM method is still used for spectrum allocation, a large amount of spectrum resources are required, which causes a shortage of spectrum resources. Compared with the ground communication, the resource allocation method of the traditional satellite communication has lower frequency spectrum utilization rate.

Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, an embodiment of the present invention provides a resource allocation method, which is applied to a network device, and includes:
step 11, allocating a first frequency resource set and a second frequency resource set for a first cell; the interference intensity of the adjacent cell on the frequency resources contained in the first frequency resource set of the first cell is smaller than a first threshold value, and the interference intensity of the adjacent cell on the frequency resources contained in the second frequency resource set of the first cell is larger than a second threshold value;
step 12, sending first resource allocation information to a terminal accessing the first cell, where the first resource allocation information is used to indicate information of a first frequency resource set and information of a second frequency resource set of the first cell.
The frequency resource of the first cell and the frequency resource of the neighboring cell in the first frequency resource set are not overlapped, or the interference of the neighboring cell on the first frequency resource set by the first cell is less than a threshold value (i.e. weak interference).
The frequency resource of the first cell and the frequency resource of the neighboring cell in the second frequency resource set are partially or completely overlapped, or the interference of the neighboring cell on the second frequency resource set by the first cell is greater than a threshold (i.e. strong interference).
It should be noted that the first threshold and the second threshold may be the same or different, and are not specifically limited herein. In a special case, the interference strength of the weak interference may be 0.
It should be noted that the resource allocation method provided in the embodiment of the present invention is applicable to a satellite mobile system and is also applicable to other wireless communication systems. For example, the network side device resource-divides all available downlink channel bandwidths into a plurality of different resource sets, and each cell selects a first frequency resource set and a second frequency resource set therein.
As shown in fig. 2, resource allocation is performed for 4 adjacent cells, and all available frequency resources are first divided into 4 orthogonal resource sets (resource set 1, resource set 2, resource set 3, and resource set 4).
One of the distribution modes is as follows: one of the orthogonal resource sets is selected as a first frequency resource set of a certain cell, and the other resource sets can be used as a second frequency resource set of the corresponding cell. For example:
and a cell 1: the first set of frequency resources = resource set 1, the second set of frequency resources = { resource set 2, resource set 3, resource set 4};
and 2, cell: the first set of frequency resources = resource set 2, the second set of frequency resources = { resource set 1, resource set 3, resource set 4};
and 3, cell: the first set of frequency resources = resource set 3, the second set of frequency resources = { resource set 1, resource set 2, resource set 4};
and 4, cell: the first set of frequency resources = resource set 4, the second set of frequency resources = { resource set 1, resource set 2, resource set 3}.
The other distribution mode is as follows: selecting one of the orthogonal resource sets as a first frequency resource set of a certain cell, and taking all the resource sets as a second frequency resource set of the corresponding cell; for example:
cell 1: the first set of frequency resources = resource set 1, the second set of frequency resources = { resource set 1, resource set 2, resource set 3, resource set 4};
and 2, cell: the first set of frequency resources = resource set 2, the second set of frequency resources = { resource set 1, resource set 2, resource set 3, resource set 4};
and 3, cell: the first set of frequency resources = resource set 3, the second set of frequency resources = { resource set 1, resource set 2, resource set 3, resource set 4};
and 4, cell: the first set of frequency resources = resource set 4, the second set of frequency resources = { resource set 1, resource set 2, resource set 3, resource set 4}.
Optionally, step 12 includes:
the first resource allocation information is transmitted to the terminal through a broadcast message (e.g., a system information block SIB) or a radio resource control RRC message.
As an alternative embodiment, after step 12, the method further comprises:
and sending first indication information to the terminal, wherein the first indication information is used for indicating that the transmission of the common channel uses the first frequency resource set.
Wherein the common channel includes: a broadcast channel PBCH, a common control channel PDCCH, a data channel PDSCH carrying broadcast information, etc. Since the information transmitted by the common channel needs to be notified to all users in the cell (i.e. including the terminals in the cell edge area and also including the terminals in the cell center area), the frequency resources in the first frequency resource set need to be used for transmitting the common channel for interference avoidance.
As another alternative, after step 12, the method further comprises:
receiving position information reported by a terminal;
under the condition that the terminal is determined to be located in the edge area of the first cell (in other words, the terminal is located in a strong interference area) according to the position information, sending second indication information to the terminal, wherein the second indication information is used for indicating that the transmission of a terminal dedicated channel uses a first frequency resource set;
and under the condition that the terminal is determined to be located in the central area of the first cell (in other words, the terminal is located in a weak interference area) according to the position information, sending third indication information to the terminal, wherein the third indication information is used for indicating that the transmission of the terminal dedicated channel uses a second frequency resource set.
Wherein, the terminal dedicated channel includes: a terminal-specific control channel PDCCH, a data channel PDSCH, etc.
In a satellite cell, a terminal in an edge region is easily interfered by a co-frequency adjacent cell, so that interference avoidance is required for a terminal dedicated channel (for example, a control channel and/or a data channel exclusive to the terminal), and frequency resources in a first frequency resource set are adopted for information transmission; and for the terminal in the central area, the frequency resources in the second frequency resource set can be adopted for information transmission.
According to the embodiment of the invention, partial frequency reuse is introduced on the basis that the traditional satellite communication frequency reuse factor is 4 or 6, so that the frequency reuse factor is less than 2, and the frequency resource rate and the system capacity are effectively improved.
For example, the terminal obtains the location information of the terminal based on a GNSS receiver, and then reports the location information to the network side device, and the network determines whether the terminal belongs to the center or the edge of the cell based on the location information of the terminal. The network needs to determine the coverage area of a beam cell according to the mapping mode of satellite beams, then the position is divided into a central area and an edge area based on the distribution characteristics of signal intensity and interference, and the beam coverage area of the satellite can be pre-judged and planned in advance on the basis of ephemeris information on the network side, so the network can be divided into two different areas in advance based on the position.
The satellite beams have a certain included angle, a satellite beam model is provided during design, and the interference and signal intensity distribution among the beams can be estimated based on the model network. According to the distance between the satellite and the ground, each beam projected on the ground by the satellite forms a beam range, if one beam is for one cell, the radius of the cell and the network side of the coverage area can be obtained in advance, that is, the base station can know the boundary area of each cell on the ground in advance, and this part of information is also called ephemeris information. The network side determines the ranges of the central area and the edge area of the cell based on the cell radius, the cell position and the expected interference threshold requirement, because the central area corresponds to the non-orthogonal set, when the central area is larger, the interference between the cells is larger, and otherwise, the interference between the cells is smaller. In fig. 3, a schematic diagram of the area coverage of the cell center and the cell edge is given.
In a high earth orbit satellite system (GEO) deployment, the satellite and the earth rotate synchronously, so the terrestrial coverage of the satellite cell is fixed, and whether the satellite belongs to the cell center area or the cell edge can be easily judged based on the terminal position. In a low earth orbit satellite system (LEO) scene, when a wave beam of a satellite adopts a fixed wave beam, the coverage area of the satellite on the ground is mobile, and at the moment, position information fed back by a terminal needs to be converted into an included angle between the terminal and a wave beam central point, because the included angle position of the wave beam, the satellite signal intensity and interference are in one-to-one correspondence, and a network judges whether the terminal belongs to a cell center or a cell edge based on the included angle. Of course, if the network side of the low earth orbit satellite system can determine the coverage area of the cell in real time, after the terminal reports the position information, the network side can directly determine whether the terminal is located in the central area or the edge area of the cell.
As an alternative embodiment, the method further comprises:
and acquiring the information of the first frequency resource set and the information of the second frequency resource set of the adjacent cell through information interaction between network side devices.
In other words, the network side device of the embodiment of the present invention obtains resource allocation set information of each neighboring cell managed by the neighboring network side device through information interaction between the network side devices; that is, each network side device sends the information of the first frequency resource set and the information of the second frequency resource set of each cell to the adjacent network side device, thereby realizing the sharing of the frequency allocation information.
Further, in the above embodiment of the present invention, the method further includes:
and sending second resource allocation information to the terminal, wherein the second resource allocation information is used for indicating the information of the first frequency resource set and the information of the second frequency resource set of the adjacent cell.
The network side device notifies the second resource allocation information in the system message, and helps the terminal to obtain the resource allocation information of the neighboring cell during cell switching or cell reselection, thereby improving the success rate of cell switching or cell reselection.
In order to more clearly describe the resource allocation method provided by the embodiment of the present invention, the following description is made with reference to an example:
the network allocates the resources of each cell into two sets; the first set of frequency resources and the second set of frequency resources, and therefore the network needs to inform the terminal of the resource allocation information, based on a broadcast message or an RRC message.
For a common broadcast channel PBCH or a PDSCH carrying SIB and a common system channel PDCCH sent by scheduling broadcast information, the information needs to be notified to all users in a cell, so a first frequency resource set needs to be adopted; for the dedicated PDCCH and PDSCH of the user, resource allocation needs to be performed based on the location of the terminal, if the terminal is located in the center of the cell, the second frequency resource set is adopted, and if the terminal is located at the edge of the cell, the second frequency resource set is adopted. This may improve resource usage, since the first set of frequency resources occupies a relatively small proportion of the total resources.
After the network obtains the location information reported by the terminal, the network needs to notify the terminal of the resource set used by the dedicated channel for receiving the PDCCH and PDSCH signals of the terminal.
When the terminal performs cell switching or cell reselection, the network needs to notify the terminal of new resource allocation information of the target cell in a switching message or a broadcast message, including resource allocation information of a common channel and resource allocation information of a dedicated channel, otherwise the terminal cannot receive broadcast and common control information of the target cell after switching. Further, the network may notify the resource allocation information of the neighboring cell before the terminal is handed over, helping the terminal to listen to the system information of the neighboring cell.
In summary, in the embodiments of the present invention, the network allocates the first frequency resource set and the second frequency resource set for the first cell, and the network allocates different frequency resource sets for data transmission based on the common channel and the terminal dedicated channel, so that the utilization rate of frequency resources can be effectively improved, and the inter-cell interference can be reduced.
As shown in fig. 4, an embodiment of the present invention further provides a resource determining method, which is applied to a terminal, and includes:
step 41, receiving first resource allocation information sent by a network side device, where the first resource allocation information is used to indicate information of a first frequency resource set and information of a second frequency resource set of a first cell;
the interference intensity of the adjacent cell on the frequency resources contained in the first frequency resource set of the first cell is smaller than a first threshold value, and the interference intensity of the adjacent cell on the frequency resources contained in the second frequency resource set of the first cell is larger than a second threshold value;
and 42, determining the frequency resource of the first cell according to the first resource allocation information.
The frequency resource of the first cell and the frequency resource of the neighboring cell in the first frequency resource set are not overlapped, or the interference of the neighboring cell on the first frequency resource set by the first cell is smaller than a threshold value (i.e. weak interference).
The frequency resource of the first cell in the second frequency resource set and the frequency resource of the neighboring cell partially or completely overlap, or the interference of the neighboring cell on the second frequency resource set by the first cell is greater than a threshold (i.e. strong interference).
Optionally, step 41 includes:
and receiving a broadcast message or a Radio Resource Control (RRC) message sent by a network side device, wherein the broadcast message or the RRC message carries the first resource allocation information.
As an alternative embodiment, the method further comprises:
receiving first indication information sent by a network side device, wherein the first indication information is used for indicating that the transmission of a common channel uses a first frequency resource set;
and transmitting a common channel according to the first indication information.
Wherein the common channel includes: a broadcast channel PBCH, a common control channel PDCCH, a data channel PDSCH carrying broadcast information, etc. Since the information transmitted by the common channel needs to be notified to all users in the cell (i.e. including the terminals in the cell edge area and also including the terminals in the cell center area), the frequency resources in the first frequency resource set need to be used for transmitting the common channel for interference avoidance.
As another alternative embodiment, the method further comprises:
reporting the position information of the terminal to network side equipment;
receiving second indication information sent by a network side device, wherein the second indication information is used for indicating that the transmission of a terminal dedicated channel uses a first frequency resource set; or receiving third indication information sent by a network side device, where the third indication information is used to indicate that the transmission of the terminal dedicated channel uses a second frequency resource set;
and the network side judges whether to send the second indication information or the third indication information to the terminal or not based on the position of the terminal, and the judgment is based on whether the terminal is positioned at the edge of the cell or at the center of the cell. If the terminal is a cell edge user, the terminal receives second indication information and indicates the first frequency resource set as the bandwidth resource of the dedicated channel; and if the user is the cell center user, the third indication information is received, and the second frequency resource set is indicated to be used as the bandwidth resource of the dedicated channel.
And transmitting the terminal dedicated channel according to the second indication information or the third indication information.
Wherein, the terminal dedicated channel includes: a terminal-specific control channel PDCCH, a data channel PDSCH, etc.
In a satellite cell, a terminal in an edge region is easily interfered by a co-frequency adjacent cell, so that interference avoidance is required for a terminal dedicated channel (for example, a control channel and/or a data channel exclusive to the terminal), and frequency resources in a first frequency resource set are adopted for information transmission; and for the terminal in the central area, the frequency resources in the second frequency resource set can be adopted for information transmission.
For example, the terminal performs geographic location positioning based on a global navigation system GNSS or other positioning technologies, and reports location information to the network side device for the network to determine the location of the terminal in the cell. The terminal receives the indication information of the common channel and the terminal dedicated channel, and receives downlink signals in different frequency resource sets aiming at different channels.
As an alternative embodiment, the method further comprises:
receiving second resource allocation information sent by a network side device, wherein the second resource allocation information is used for indicating information of a first frequency resource set and information of a second frequency resource set of an adjacent cell;
and determining the frequency resource of the adjacent cell according to the second resource allocation information.
For example, the network side device notifies the second resource allocation information in the system message, and helps the terminal to obtain the resource allocation information of the neighboring cell during cell handover or cell reselection, thereby improving the success rate of cell handover or cell reselection.
In summary, in the embodiments of the present invention, the network allocates the first frequency resource set and the second frequency resource set for the first cell, and the network allocates different frequency resource sets for data transmission based on the common channel and the terminal dedicated channel, so that the utilization rate of frequency resources can be effectively improved, and the inter-cell interference can be reduced.
