  • Mobile communication has greatly changed people's lives. With the development of mobile communication and the increasing demand for communication, users' requirements for mobile network quality are also increasing. The most widely used mobile communication application is personal mobile communication, and its cellular mobile system dominates.

  • the cell is covered by one transceiver for each cell.
  • This transceiver is called a base station.
  • BS Businesses in the entire cell complete communication by this base station. Since the wireless cellular network can use the same frequency resource in different cells, different 7 cells in Figure 1 use the same frequency resource. By using only a narrow frequency band, mobile communication services can be provided for the entire service area, which greatly saves frequency resources.
  • the frequency reuse technique refers to a radio channel of the same carrier frequency covering different cells, and cells using the same carrier frequency are separated by a certain distance to suppress the co-channel interference within an acceptable range.

  • AMPS Advanced Mobile Phone System
  • the more popular frequency reuse method in TACS system is 7/21 multiplexing. 7/21 multiplexing is to divide all frequency points into 21 cells of 7 base stations (in the cellular system, each base station is generally used). Divided into 3 cells), the frequency points in these 21 cells are not reused, and the 21 cells are used as one extension.
  • the Park structure is reused throughout the network. From this relationship, we can see that the highest carrier frequency configuration of each cell depends on two factors, one is the frequency resource owned by the operator, and the other is the frequency reuse mode adopted in the network design. Taking 7/21 multiplexing as an example, the highest carrier frequency configuration per cell is equal to all frequency points /21. We also call 21 the frequency reuse factor, which is a major parameter to measure the degree of easing of a network frequency reuse.
  • the 4/12 frequency reuse method was more popular. Compared with the 7/21 multiplexing of the TACS system, it has been used in the utilization of frequency resources. There has been a big improvement.
  • the 4/12 structure has a multiplexing factor of 12, which can allocate more carrier frequencies in each cell than 21, providing more capacity per unit area. However, it uses the frequency of the four base stations as a group, and the 7/21 multiplex with 7 base stations is smaller than the same frequency separation distance.
  • the GSM system is able to use a more compact frequency reuse technique because it uses digital modulation technology, and the signal is much stronger than analog signals in terms of anti-fading and anti-interference.
  • the frequency reuse coefficient only needs to reach 3 to guarantee any two.
  • the frequencies used by neighboring cells are different, as shown in Figure 2, so that the limited frequency resources can be better utilized, and each cell can be configured more when the frequency resources owned by the operators are unchanged. Carrier frequency.
  • inter-cell interference coordination is for downlink resource management, that is, adding constraints (such as the construction of common channels and the scheduling of non-ordinary channels) in a coordinated manner between cells, which are usually restrictions on resource managers.
  • constraints such as the construction of common channels and the scheduling of non-ordinary channels
  • the small-interval interference coordination technology mainly has frequency soft multiplexing technology.
  • Frequency soft multiplexing also known as partial frequency multiplexing, means that users in the center of each cell in the same mobile communication network can use the same frequency, but must transmit and receive at a lower power, while users at the edge of each cell use the frequency.
  • the multiplexing method ensures that two adjacent cells use different frequencies.
  • the mobile communication network uses a frequency reuse coefficient greater than 1 for a cell edge region where interference is severe, and a frequency reuse coefficient of 1 for a cell interior.
  • the frequency reuse coefficient is 3, as shown in FIG. 3, the frequency is first divided according to the multiplexing coefficient of 3, and each cell obtains its own primary frequency. For each cell, the frequency other than its dominant frequency is called the secondary frequency. . That is to say, the primary frequency of the cell 1 becomes the secondary frequency in the cell 2.
  • the available power on the secondary frequency needs to be limited, to ⁇ : to be lower than the primary frequency.
  • the user inside the cell can use the primary frequency or the secondary frequency to transmit or receive signals arbitrarily, and the user at the edge of the cell can only use the primary frequency to transmit or receive signals, thereby preventing the signals of the cell edge users from being interfered by other cells.
  • the main reason for this situation is that since the unicast frequency soft multiplexing needs to divide the specified frequency resources, all the frequency resources are divided into the primary frequency and the secondary frequency of each cell, so that no frequency band is reserved for the network side. Broadcast multicasting is performed, and since broadcast multicasting does not occur frequently on the network side, if part of the frequency band is divided from the designated frequency resources dedicated to broadcast multicast, the resources cannot be fully utilized.
  • the technical problem to be solved by the embodiments of the present invention is to provide a frequency band allocation method and a device thereof, to solve the problem that the unicast service using the frequency division multiplexing technology in the prior art cannot be compatible with the same frequency broadcast multicast service.

Abstract

L'invention concerne un procédé et un dispositif d'attribution de bande destinés à l'usage plus efficace d'une ressource de bande limitée. Dans cette invention, seule une partie de bande sera attribuée comme sous-bande pour une diffusion-multidiffusion selon la même fréquence au moment ou celle-ci est nécessaire, la bande résiduelle étant utilisée pour une monodiffusion sous forme de coordination d'interférences entre cellules. La bande résiduelle peut être réattribuée entre les cellules dans le modèle de coordination d'interférences ou conserver le même type d'attribution lorsque la diffusion-multidiffusion n'est pas nécessaire. Une bande peut également être attribuée dans un multiplexage temporel, seuls certains créneaux temporels appartenant à la sous-bande destinée à une diffusion-multidiffusion dans la même fréquence étant attribués, tous les autres créneaux temporels appartenant à la bande résiduelle pour monodiffusion dans un multiplexage en fréquence souple. Des moyens de saut de fréquence peuvent également être combinés de sorte qu'une diffusion-multidiffusion peut utiliser une bande différente dans un créneau temporel différent.
