Description
Technical Field
The invention belongs to the technical field of wireless communication, and particularly relates to an interference coordination method and device for adjacent cells under the same-frequency networking.
Background
In a cellular mobile communication system, a mobile station, i.e. a network terminal device, can communicate with a base station via a radio channel within an area covered by one base station or a sector antenna of the base station, such an area being a cell. In order to effectively connect different cells and achieve the purpose of efficiently utilizing the frequency spectrum, adjacent cells are often networked by using the same frequency band, namely, the same frequency band networking. Under the same-frequency networking, because the adjacent cells use the same frequency for data transmission, the marginal users at the junctions of the adjacent cells can obtain lower communication quality due to the mutual influence of wireless channels and the phenomenon of signal superposition, namely the same-frequency interference.
In the prior art, one main technical means for solving the co-channel interference is to coordinate the frequency domain resources or the frequency spectrum using time periods of the cell edge users, i.e. adopt a strategy of frequency domain resource division or time-sharing scheduling, so as to avoid the phenomenon of signal superposition of the co-frequency domain and the co-time period. One more specific implementation means is as follows: dividing a cell into edge users and center users, adopting a mode of time-sharing scheduling or authorizing different frequency domain resources for the center users and the edge users of the same cell, combining a power control algorithm, weakening communication interference of the center users to the edge users, and/or adopting a mode of different scheduling or inapplicable to the same frequency domain resource scheduling for the edge users of adjacent cells, avoiding the edge users of the adjacent cells from using the same time-frequency resources, and realizing the purpose that the edge users of the adjacent cells are not interfered with each other in communication.
The above interference coordination technique can effectively reduce co-channel interference phenomenon of adjacent cells, but has the following problems: (1) If the frequency domain resources which can be scheduled by the central user and the edge users are divided in coordination, the edge users are forced to increase the scheduling times due to limited resources which can be used once, the requirement on the downlink control channel of the networking network is obviously increased, and the influence on the small-bandwidth communication network is particularly obvious. In some special small bandwidth networks, such as narrowband internet of things (Narrow Band Internet of Things, NB-IoT), the coordination mode is practically inapplicable because its cell bandwidth is only 1 RB; (2) If a time-sharing scheduling strategy is adopted for the central user and the edge users in coordination, the terminal scheduling times of the edge users are reduced in practice, the service scheduling of the edge users is possibly insufficient, meanwhile, the difficulty of a scheduling algorithm is obviously increased, and the requirement on a networking network is high; in addition, in some special networks, such as NBIoT, due to the existence of a large number of repeated transmissions and the requirement for GAPs, the scheduling time of the central user and the edge user cannot be actually and clearly divided, which makes the coordination method difficult to apply.

Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Example 1
The embodiment of the invention provides an interference coordination method under the same-frequency networking, as shown in fig. 1, comprising the following steps:
S101: before data transmission, generating a scrambling sequence of a cell, wherein the scrambling sequence comprises a first scrambling code part which is mapped with basic CRNTI identifiers of the cell one by one and a second scrambling code part which is mapped with basic PCI identifiers of the cell one by one, and the basic CRNTI identifiers are CRNTI identifiers before user allocation or authorization is carried out.
The PCI identifier (Physical-LAYER CELL IDENTITY, physical layer cell identifier) is an identifier for uniquely identifying a certain Physical cell in a cellular mobile communication system, and directly determines the positions of a main synchronization signal and a reference signal used by each cell, and is the first network side information identified when a terminal is started or initially accesses the cell. The CRNTI (Cell Radio Network Temporary Identifier ) identifier is obtained from a subsequent system broadcast message after the terminal completes synchronization with the base station and identifies the PCI, and is a dynamic identifier allocated to User Equipment (UE) by the base station, and can uniquely identify the UE under a cell air interface.
In the prior art, when planning a wireless network or optimizing the network, interference among some basic wireless signals needs to be avoided, the basic wireless signals are usually determined by the PCI identifiers, and the orthogonality of the basic wireless signals can be realized through the orthogonality of the PCI identifiers, so that the scrambling codes corresponding to the PCI identifiers of the adjacent cells generally have orthogonality.
In a more specific embodiment, the scrambling code sequence is generated by a scrambling code generator using a generation model of:
Cinit＝nPCI+nCRNTI·215
Wherein C init represents a scrambling code initialization value, n CRNTI represents a scrambling code value mapped one-to-one with a basic CRNTI identification, which forms the first scrambling code portion, and n ID represents a scrambling code value mapped one-to-one with a basic PCI identification, which forms the second scrambling code portion.
S102: the first scrambling code part is divided into a plurality of mutually orthogonal scrambling code groups, wherein the scrambling code of any scrambling code group is orthogonal with the scrambling codes of other scrambling code groups.
If the scrambling code sequence is generated according to model C init＝nPCI+nCRNTI·215, then the N CRNTI·215 portion is further divided into N mutually orthogonal scrambling code groups N 1、N2、……Ni … …, where i represents the scrambling code group ordinal, resulting in scrambling code group N i. It should be noted that the number of scrambling code groups and the number of scrambling codes included in the first scrambling code section are divided as needed, and the scrambling codes included in the first scrambling code section are not necessarily all divided into scrambling code groups.
In a more specific embodiment, the partitioning of the scrambling code group may be achieved by orthogonal coding (Orthogonal Coding).
Wherein the orthogonal coding is a technique for canceling multiple interference signals, which groups the signals so that there is no phase or frequency overlap of the signals in each group to ensure that the signals of each group do not interfere with each other.
Through the implementation steps, a plurality of mutually orthogonal scrambling code groups can be generated, and users scrambled by the scrambling code groups can not influence each other during data demodulation, so that basic interference coordination is realized.
S103: and determining the CRNTI identification corresponding to the scrambling code of each scrambling code group in the basic CRNTI identification of the cell according to the mapping relation between the first scrambling code part and the basic CRNTI identification of the cell, and forming the CRNTI identification corresponding to each scrambling code group into a CRNTI identification group.
If the scrambling code sequence is generated according to the model C init＝nPCI+nCRNTI·215, where the N CRNTI·215 portion is further divided into N mutually orthogonal scrambling code groups N 1、N2、……Ni (i represents the scrambling code group ordinal number), the scrambling code sequences correspondingly form N scrambling code groups, and the scrambling code in each scrambling code group is from the first scrambling code portion, then the CRNTI identifier corresponding to each scrambling code group can be determined, and then the CRNTI identifier corresponding to each scrambling code group can be formed into a CRNTI identifier group.
S104: and respectively granting CRNTI identifications of different CRNTI identification groups for respective edge users of the adjacent cells.
The CRNTI identifiers used by the respective edge users of the adjacent cells are not from the same CRNTI identifier group, and the scrambling codes in the scrambling code groups corresponding to different CRNTI identifier groups are mutually orthogonal, so that the respective edge users of the adjacent cells cannot influence each other when data transmission is carried out, and interference coordination is realized.
The embodiment of the invention can fully ensure that the edge users of the adjacent cells can use the same frequency band simultaneously and without interference when receiving or transmitting transmission data, thereby realizing the efficient utilization of frequency spectrum and avoiding the interference between signals.
Further, the interference coordination method in the embodiment of the invention further comprises the following steps: s105: when the central user moves to the cell edge to become an edge user, if the CRNTI identifier currently used by the central user is not from the CRNTI identifier group, the central user is re-granted with the CRNTI identifier from the CRNTI identifier group.
After the central user of the cell becomes the edge user, the originally used CRNTI identifier may not come from the CRNTI identifier group, if the original CRNTI identifier is still used, the originally used CRNTI identifier may interfere with the edge user of the neighboring cell, and by re-granting the CRNTI identifier from the CRNTI identifier group, the interference may be avoided. Specifically, the CRNTI identification of the central user is granted through an RRC (Radio Resource Control, radio resource management) reconfiguration procedure.
