Description

Spectrum scheduling method and network equipment applied to multiple systems

Technical Field

The present application relates to the field of communications, and in particular, to a spectrum scheduling method and network device applied to multiple systems.

Background

With the rapid development of Mobile Broadband Business (MBB) users, spectrum owned by operators is becoming more and more scarce, and how to simultaneously deploy systems of multiple systems in a limited spectrum is a major problem facing operators, such as simultaneous deployment of global system for mobile communications (GSM) and Universal Mobile Telecommunications System (UMTS), or simultaneous deployment of UMTS and Long Term Evolution (LTE). When the method is applied to a GSM/UMTS dual-mode system (GU) or a UMTS/LTE dual-mode system (UL), for a downlink direction, a base station side can control receiving and sending through a technology of a network side, and for an uplink direction, a terminal side always transmits signals with a bandwidth defined by a protocol. As shown in fig. 1A, in a GU scenario, downlink interference between the GU can be solved by a filtering technique in the downlink; in the uplink direction, GU spectrum overlapping area, GSM and UMTS uplink transmit power, which causes serious uplink interference between GU.

In the existing scheme, the performance of each system under an interference scene is respectively improved. For example, for a GU scenario, at the UMTS side, a baseband narrowband notch technique is adopted to eliminate GSM strong interference, as shown in fig. 1B; and, at the GSM side, a coordinated multipoint transmission/reception (CoMP) technology, a Multidimensional Interference Cancellation and Combining (MICC) technology, and the like are adopted to improve the uplink performance, as shown in fig. 1C. And reducing the receiving total bandwidth power (RTWP) of the system.

The existing scheme can only reduce the interference between a UMTS system and other systems, but can not thoroughly solve the problem of signal interference in the uplink direction.

Detailed Description

In order to make the technical field better understand the scheme of the present application, the following description will be made on the embodiments of the present application with reference to the attached drawings.

References throughout this specification to "first" or "second", etc., are intended to distinguish between similar items and not necessarily to describe a particular order or sequence. Furthermore, references throughout this specification to "comprising" or "having" and any variations thereof are intended to cover non-exclusive inclusions, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

In a deployment scenario of a multi-system, due to the limited width of a spectrum, systems of different systems may need to share the same spectrum. For example, global system for mobile communications (GSM) and Universal Mobile Telecommunications System (UMTS), GU scenarios, are deployed and deployed at the same time; or simultaneously deploy UMTS and Long Term Evolution (LTE), i.e., UL scenarios; or simultaneously deploying UMTS and UMTS, namely UU scenes; or simultaneously deploy UMTS and 5G networks, i.e., U &5G scenarios. In different application scenarios, different systems generate interference.

In the existing scheme, when spectrum sharing is performed in the UL scenario, as shown in fig. 2, the conditions to be satisfied during frequency band sharing are as follows: the UMTS can not fall into the unilateral minimum bandwidth of LTE except for the sideband; the LTE single-sided minimum bandwidth cannot fall within the UMTS downlink core bandwidth. Since the UMTS uplink transmission spectrum can be limited to 5MHz but cannot be limited to a narrower bandwidth, the overall shared bandwidth of the UL is greatly limited. In the downlink direction, the spectrum cannot be fully utilized due to the static sharing mode, the sideband is 0.6MHz, the transmitting power of UMTS is relatively small, interference still exists on the common channel of LTE, and the performance of LTE still suffers. In the existing scheme, only the interference between UL systems can be reduced, but the problem of interference of UMTS to LTE in the uplink direction cannot be thoroughly solved. In the downlink direction, the UL static shared spectrum has a low utilization rate and poor flexibility, and cannot really play the value of UL sharing.

In order to solve the problem of signal interference in the uplink direction between multi-system systems (e.g., UMTS and other same or different systems), the present application provides a spectrum scheduling method applied to multiple systems, which is used to eliminate the problem of signal interference in the uplink direction when multiple systems are deployed, and simultaneously improve the utilization rate of spectrum sharing in the downlink direction.

The method and the device can be applied to the scenes of the multi-system deployment, such as GU scenes; or in UL scenarios; or in a UU scene; or in a U &5G scenario. In order to simplify the process, the process of the GU and UL scenarios is described in detail only by taking the example of solving the uplink interference problem and the downlink spectrum sharing problem in the GU and UL scenarios through a dual-cell high speed downlink packet access (DC-HSDPA) scheduling method, and the processes in other scenarios are similar to those in the GL and UL scenarios, and are not described herein again.

It can be understood that, for Carrier Aggregation (CA) in an LTE system or dual-band high-speed downlink packet access (DB-HSDPA) in UMTS, similar to the scheduling method of DC-HSDPA in the present application in principle, uplink carrier non-signaling in a cross-band may be implemented, so as to solve the uplink interference problem, and details are not described here.

For convenience of understanding, a specific flow of the embodiment of the present application is described below, and with reference to fig. 3, in a GU scenario, an embodiment of the method for scheduling spectrum applied to multiple systems in the embodiment of the present application includes:

301. the network device determines a scheduling policy for dual carrier high speed downlink packet access DC-HSDPA.

A network device (e.g., a Radio Network Controller (RNC) in UMTS, or a base station eNodeB in LTE, etc.) determines a scheduling policy for dual-carrier high-speed downlink packet access DC-HSDPA, where the scheduling policy is used to prohibit a User Equipment (UE) from transmitting an uplink signal on a secondary carrier of a universal mobile telecommunications system UMTS. The scheduling policy may be implemented by configuration, or may be implemented by a preset algorithm, which is not limited herein.

It should be noted that the dual-carrier high-speed downlink packet access DC-HSDPA related in the present application further includes flexible dual-carrier high-speed downlink packet access flexible DC-HSDPA, and details are not described here.

The network device referred in this application may be an RNC in UMTS, an eNodeB in LTE, or a gNodeB in a 5G system, and different devices are selected according to different actual application scenarios, which is not limited herein.

Specifically, step 301 may be split into the following steps:

301a, the network device sets the cell selection and reselection parameters of the secondary carrier to the camping prohibition state.

The network device sets the cell selection and reselection parameters SIB3 and SIB4 of the secondary carrier to a camping prohibition state.

Wherein, SIB3 is a cell reselection parameter for the UE in Idle (Idle) mode. SIB4 is a cell reselection parameter for the UE in the connected state.

Specifically, the network device sets a Cell Access Restriction parameter (Cell Access Restriction) in SIB3 and SIB4 to a disabled state. In order to set the Cell Access response to the forbidden state, at least a Cell forbidden identifier (Cell Barred) and an Intra-frequency reselection identifier (Intra-frequency Cell re-selection indicator) in the Cell Access response are required to be modified to the forbidden state, that is, a value of the Cell Barred is set to be Barred, and a value of the Intra-frequency Cell re-selection indicator is set to be notlower; and modifying the cell barring time length (Tbarred) to a preset maximum time length, namely setting the value of Tbarred to D1280.

It should be noted that the parameter setting in the Cell Access response may be executed simultaneously, or may be set according to a preset sequence, which is not limited herein.

Step 301b, the network device sets the cell where the secondary carrier is located as being unable to reselect, and/or unable to redirect, and/or unable to switch.

The network equipment adds a prohibition identifier in the configuration information of the auxiliary carrier, wherein the prohibition identifier is used for indicating that a cell where the auxiliary carrier is located cannot be reselected by the UE and cannot be redirected by the UE.

It should be noted that reselection, redirection, handover, and the like are not possible, and they may be set simultaneously or partially selected for setting, and are not limited herein.

Step 301c, the network device deletes the cell where the secondary carrier is located from the pilot frequency handover neighbor cell information list.

The network equipment deletes the cell where the auxiliary carrier is located from the pilot frequency switching neighbor cell information list, wherein the pilot frequency switching neighbor cell information list is contained in the configuration information of the auxiliary carrier.

It should be noted that. The steps 301a, 301b, and 301c are in a parallel relationship, and may be executed simultaneously, or may be executed sequentially according to a preset sequence, which is not limited herein.

302. And the network equipment sets the power parameter of the common channel of the secondary carrier to be the minimum value.

And the network equipment sets the power parameter of the common channel of the secondary carrier to be the minimum value.

Specifically, the network device may set the power parameter of the common channel other than the pilot channel to a minimum value. For example, a Physical Shared Channel (PSCH) is generally adjusted according to a measurement result of an actual environment, so that the transmission power meets requirements of UE reception and modulation, and in the present application, a network device may adjust a value of a power parameter PSCHPower of the PSCH to a minimum value of-35, where the physical shared channel includes a Physical Uplink Shared Channel (PUSCH) and a Physical Downlink Shared Channel (PDSCH), and may select any one or all of them to be set. As another example, the network device may adjust the value of the parameter SSCHPower in the Secondary Synchronization Channel (SSCH) to a minimum value of-35; the network device may adjust a value of a power parameter PCHPower of a Primary Common Control Physical Channel (PCCPCH) to a minimum value of-35; the network device may adjust a value of a power parameter PCHPower of a Secondary Common Control Physical Channel (SCCPCH) to a minimum value of-35; the network device may adjust a value of an Access Indicator Channel (AICH) power parameter aichpowermefset to a minimum value of-22; the network device may adjust a value of a power parameter pichpowerreffset of a Paging Indicator Channel (PICH) to a minimum value of-10; the network device may adjust a value of a power parameter BCHPower of a Broadcast Channel (BCH) to a minimum value of-35; the network device may adjust the value of the Forward Access Channel (FACH) power parameter MaxFachPower to a minimum value of-35.

It should be noted that the network device may adjust the values of the power parameters of one or more channels of the plurality of common control channels except for the pilot channel to minimum values, which is not limited herein. The network device may also reduce power by adjusting other parameters of the common channel, which is not limited herein.

It is to be appreciated that step 302 is optional and that interference to other systems from UMTS is minimized by transmitting at a minimum power on the common channel of the secondary carrier.

303. And the network equipment sends the scheduling strategy and the power parameter of the common channel of the auxiliary carrier to the user equipment.

The network equipment sends the scheduling strategy and the power parameter of the common channel of the auxiliary carrier to the UE, so that the UE communicates according to the received scheduling strategy and the power parameter of the common channel of the auxiliary carrier, the purpose of forbidding the user equipment to use the UMTS auxiliary carrier is achieved, and the UMTS auxiliary carrier does not have uplink signals.

In the embodiment of the application, the network equipment controls the modes of residence, reselection, switching, redirection and the like of the user equipment, common users are prohibited from using the auxiliary carrier, no uplink signal of the auxiliary carrier is realized, and the problem of interference in the uplink direction of a multi-system is solved.

Referring to fig. 4, in an UL scenario, another embodiment of a spectrum scheduling method applied to multiple systems in the embodiment of the present application includes:

401. the network device obtains scheduling information for each transmission time interval TTI.

The network device obtains scheduling information of each Transmission Time Interval (TTI) in the LTE system, and at this time, the network device is a device on the UMTS side.

It should be noted that, the systems of the two systems of UMTS and LTE support a TTI-level fast interaction channel in or between base stations, and support real-time information interaction of the two systems.

It can be understood that the scheduling information of the TTI acquired by the network device may be acquired from an LTE system across systems, for example, the network device on the UMTS side; or the network device on the UMTS side may be of the same system, and is obtained from the inside of the system, which is not limited herein.

402. And the network equipment determines a spectrum allocation mode according to the scheduling information.

And the network equipment determines the UL frequency spectrum allocation mode according to the scheduling information of each TTI, wherein the frequency spectrum allocation mode is a frequency division + time division mode. And controlling the allocation of the downlink frequency spectrum according to a preset priority principle. In the UMTS system priority scenario: the UMTS experience is preferentially ensured in the scene, when the UMTS has a high data transmission requirement, a Radio Network Controller (RNC) at the UMTS side informs an LTE side base station (eNodeB) that the shared spectrum needs to be occupied all the time, and the LTE can not occupy the spectrum; when the UMTS has no high data transmission requirement, the RNC at the UMTS side informs the eNodeB at the LTE side that the shared spectrum is in an available state, and in the state, the eNodeB at the LTE side can use an LTE priority mode to occupy the spectrum as required.

It is understood that the spectrum allocation pattern may be controlled by the eNodeB in addition to the RNC, specifically, in the LTE-first scenario: in the scene, the LTE experience is preferentially ensured, and when the LTE has a high data transmission requirement and needs to occupy a shared spectrum, the eNodeB on the LTE side informs the NodeB on the UMTS side of filtering aiming at the shared spectrum through a quick interaction channel; when the data transmission requirement of the LTE is low or the number of data transmission requirements is not large, and the shared spectrum does not need to be occupied, the eNodeB on the LTE side notifies the NodeB on the UMTS side to not filter the shared spectrum through a fast channel. When spectrum sharing and allocation are directly performed by the eNodeB and the NodeB, the RNC needs to send the configured configuration information to the eNodeB and the NodeB, which is not limited herein.

It should be noted that, the time delay between the UMTS and LTE channels has a certain correlation with the system load, and when the system load is low, the end-to-end interaction time delay of the two systems is small, so that real-time information interaction can be achieved; when the system load is high, the end-to-end interaction time delay of the two systems is large, and real-time information interaction cannot be achieved. Therefore, the problem of spectrum utilization loss under high interaction delay needs to be solved. In a high-interaction time-delay scene, when a certain system needs to use a frequency spectrum, the shared frequency spectrum can be used only by the system after another system gives the frequency spectrum, and the problem that frequency spectrum resources are not used timely is inevitably introduced. The method introduces a cell spectrum resource occupation prediction algorithm, and specifically includes Channel Quality Information (CQI), Rank Indication (RI), Modulation and Coding Set (MCS), and the like according to cache information of all users in the cell, and predicts a time when a spectrum needs to be used in a system in advance, so as to inform another system of releasing the spectrum in advance, and overcome the problem of spectrum utilization reduction caused by too long channel delay.

403. And the network equipment sets the power parameter of the common channel of the secondary carrier to be the minimum value.

Step 403 is similar to step 302 and will not be described herein.

It should be noted that step 403 may also precede step 401; or, after step 401 and before step 402, which is not limited herein.

404. And the network equipment sends the power parameter and the spectrum allocation mode of the common channel of the secondary carrier to the user equipment.

The network equipment sends the power parameter and the spectrum allocation mode of the common channel of the auxiliary carrier to the user equipment, so that the user equipment can communicate according to the received power parameter and the spectrum allocation mode of the common channel of the auxiliary carrier, the purpose of forbidding the user equipment to use the UMTS auxiliary carrier is realized, the UMTS auxiliary carrier has no uplink signal, the sharing of the spectrum in the downlink direction is realized, and the spectrum efficiency in the downlink direction is improved. The method has the advantages that the shared spectrum can be occupied at any time due to the fact that the LTE side has transmission requirements in an LTE priority mode scene, the system performance of the UMTS can be guaranteed preferentially in an UMTS priority mode scene, the LTE can occupy the shared spectrum when the UMTS requirements are less, and the spectrum efficiency in the downlink direction is improved.

According to the embodiment of the application, according to the determined spectrum allocation mode, spectrum sharing in the downlink direction of the spectrum of the auxiliary carrier is realized in dual-carrier high-speed downlink packet access deployment, the utilization rate of the spectrum is improved, and the overall performance of the system is improved.

It should be noted that, in addition to the GU scene and the UL scene, the embodiment of the present application may be applied to other scenes, for example, a UU scene, a U &5G scene, and the like, and the spectrum conditions in different application scenes are also different. Specifically, in the GU scenario, the UMTS secondary carrier uplink does not transmit power, and the UMTS secondary carrier downlink and GSM are completely overlapped, as shown in fig. 5A; in the UU scenario, the UMTS secondary carrier uplink does not transmit power, and the UMTS secondary carrier downlink and the main carrier are not overlapped completely, as shown in fig. 5B; in the UL scenario, the UMTS secondary carrier uplink does not transmit power, and the UMTS secondary carrier downlink and LTE perform time division + frequency division sharing, as shown in fig. 5C; in the U &5G scenario, the UMTS secondary carrier does not transmit uplink, the UMTS secondary carrier serves as an uplink frequency band for 5G uplink and downlink separation, and the secondary carrier exclusively shares a downlink frequency spectrum, as shown in fig. 5D.
