The technical solution in the embodiment of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention. It is clear that the described embodiments are only a part of the embodiments of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention. An embodiment of the present invention provides a method for semi-persistent scheduling, which may be performed by a first base station. As shown in FIG. 1, the method includes:

 01. The first base station sends semi-persistent scheduling resource configuration information and semi-persistent scheduling activation information to the second base station.

 Optionally, the first base station and the second base station store the semi-persistent scheduling resource configuration information and the semi-persistent scheduling activation information.

 Optionally, the semi-persistent scheduling resource configuration information in step 01 may be, but is not limited to, being sent to the second base station by using RRC (English full name: Radio Resource Control).

 In addition, the semi-persistent scheduling resource configuration information includes uplink semi-persistent scheduling resource configuration information and/or downlink semi-persistent scheduling resource configuration information. The uplink semi-persistent scheduling resource configuration information includes one or any of the following types: Semi-persistent scheduling-Cell radio resource temporary identifier (English name: Semi-persisten scheduling-Cell Radio Network Temporary-Identifier, English abbreviation: SPS C- RNTI), semi-persistent scheduling period, uplink power control parameters. The downlink semi-persistent scheduling resource configuration information includes one or any of the following: semi-persistent scheduling - cell radio resource temporary identifier, semi-persistent scheduling period, and hybrid automatic repeat request process (English full name: Hybrid Automatic Repeat Request process, English) Referred to as: HARQ process).

 In addition, the sending, by the first base station, the semi-persistent scheduling resource configuration information to the second base station may be implemented by using the following two methods:

 The first method: the first base station separately sends the semi-persistent scheduling resource configuration information to multiple second base stations.

The multiple second base stations are all base stations that need to receive the semi-persistent scheduling resource configuration information. a second method: the first base station first sends the semi-persistent scheduling resource configuration information to one or more second base stations, and then the second base station that first receives the semi-persistent scheduling resource configuration information The persistent scheduling resource configuration information is sent to other second base stations.

 Optionally, the semi-persistent scheduling activation information in the step 01 includes the uplink semi-persistent scheduling activation information and/or the downlink semi-persistent scheduling activation information, where the uplink and downlink semi-persistent scheduling activation information includes at least one of the following: Block allocation, modulation coding method, transport block size. Semi-persistent scheduling activation information may also be referred to as semi-persistent scheduling resource allocation information, including downlink resource allocation.

(downlink assignment) and uplink grant (uplink grant). The first base station may transmit the same or different semi-persistent scheduling activation information to one or more second base stations multiple times.

 02. The first base station, according to the semi-persistent scheduling resource configuration information and the semi-persistent scheduling activation information, and the second base station communicate with the user equipment at a semi-persistent scheduling time.

 Optionally, after the first base station determines the semi-persistent scheduling resource configuration information and the semi-persistent scheduling activation information, the SPS is obtained according to the preset activation policy (English full name: Semi-persistent scheduling, Chinese full name: semi-persistent scheduling) The subframe information, and the system frame number and the subframe number information corresponding to the SPS are sent to one or more second base stations, so that the second base station can perform resource allocation information according to a preset activation policy, semi-persistent scheduling, and Semi-persistent scheduling activation information acquires semi-persistent scheduling time. The preset activation policy may be set to follow the following formulas (1), (2), (3). When the first base station sends the new semi-persistent scheduling activation information to the second base station, the first base station acquires the subframe information corresponding to the new SPS according to the same preset activation policy, and sets the system frame corresponding to the new SPS. The number and subframe number information are sent to one or more second base stations.

 For the downlink SPS activation information, the subframe information in which the downlink downlink SPS resource allocation is located is:

(10 * SFN + subframe) = [(10 * SFNstart time + subframestart time) + N * semiPersistSchedlntervalDL] modulo 10240 Formula (1)

SFN (English full name: System Frame Number, Chinese full name: cell system frame number counter) refers to the system frame number where the second SPS time is located; subframe refers to the subframe number where the Nth SPS time is located; SFNstart Time refers to the system frame number corresponding to the downlink SPS activation information; the subframe start time refers to the subframe number corresponding to the downlink SPS activation information; The semiPersistSchedlntervalDL refers to a downlink semi-persistent scheduling period, and the downlink semi-persistent scheduling period is configured through RRC; Modulo is a modulo operation.

 HARQ Process ID = [floor(CURRENT_TTI/semiPersistSchedIntervalDL)] modulo numberOfConfSPS-Processes, where CURRENT_ TTI=[(SFN * 10) + sub frame number] Formula ( 2 )

The HARQ process ID refers to the HARQ process ID, and determines the number of HARQ processes based on the HARQ process number; CURRENT_TTI is the current scheduling time interval; floor points to the next rounding operation; number Of ConfSPS-Processes refers to the downlink SPS configured through RRC signaling HARQ process number information.

 For the uplink SPS activation information, the subframe information in which the Nth uplink SPS resource allocation is located: (10 * SFN + subframe) = [(10 * SFNstart time + subframestart time) + N * semiPersistSchedlntervalUL + Subframe - Offset * (N modulo 2)] modulo

10240 Equation (3) where semiPersistSchedlntervalUL is the uplink semi-persistent scheduling period; Subframe_Offset is 0 for the frequency division duplex FDD mode and determined by Table 1 for the time division duplex TDD mode.

Table 1 : Subframe Offset values subframe offset value

It is to be noted that, when the first base station sends the semi-persistent scheduling activation information, the system frame number and the subframe number corresponding to the SPS resource to the second base station, the sending manner is the same as the foregoing step 01, to the second base station. The implementation method of sending semi-persistent scheduling resource configuration information is the same, and will not be described in detail here.

 In addition, it is worth noting that the semi-persistent scheduling activation information provides a semi-persistent scheduling resource, and the semi-persistent scheduling configuration information provides a semi-persistent scheduling period, which enables semi-persistent scheduling activation information to periodically use semi-persistent scheduling according to a semi-persistent scheduling period. Resources. The semi-persistent scheduling time obtained in this step may be a series of times for performing semi-persistent scheduling, where the time is the start time of the subframe number corresponding to the SPS activation information, and the SPS period in the SPS configuration information is used as the period. a series of time.

 Optionally, the first base station may also abandon the current semi-persistent scheduling resource; and send the dynamic scheduling information to the second base station; and the second base station according to the dynamic scheduling information, to replace the current semi-persistent scheduling Communicating with the user equipment.

Further, in the semi-persistent scheduling process, dynamic scheduling may be performed at a certain semi-persistent scheduling time. At this time, the first base station and the second base station temporarily abandon the current semi-persistent scheduling resource, and continue after the time for performing the dynamic scheduling. According to the previous semi-persistent scheduling resources and user equipment Line communication. If the backhaul link between the first base station and the second base station is an ideal link, that is, a zero delay, the first base station sends dynamic scheduling signaling to the user equipment at a certain semi-persistent scheduling time, and sends dynamic scheduling signaling to the The second base station, the first base station and the second base station communicate with the user equipment according to the dynamic scheduling signaling. If the backhaul link between the first base station and the second base station has a certain delay, the first base station needs to determine the content of the dynamic scheduling signaling in advance, and dynamically schedule the signaling before sending the dynamic scheduling signaling to the user equipment. The content is sent to the second base station, and then the first base station sends dynamic scheduling signaling to the user equipment at a certain semi-persistent scheduling time, and the first base station and the second base station communicate with the user equipment according to the dynamic scheduling signaling.

 Optionally, the first base station sends the semi-persistent scheduling deactivation information to the user equipment, so that the user equipment deactivates the semi-persistent scheduling resource according to the semi-persistent scheduling deactivation information.

 Optionally, the first base station sends the semi-persistent scheduling deactivation information to the second base station, so that the second base station deactivates the semi-persistent scheduling resource according to the semi-persistent scheduling deactivation information.

 Optionally, after the first base station sends the semi-persistent scheduling deactivation information to the user equipment, the user equipment feeds back the semi-persistent scheduling deactivation confirmation information to the first base station. Similarly, the second base station receives the first base station sends the acknowledgement information. After the semi-persistent scheduling deactivation information, the semi-persistent scheduling resource deactivation response information may be sent to the first base station.

 Optionally, the first base station sends the semi-persistent scheduling resource reconfiguration information to the user equipment, so that the user equipment translates the semi-persistent scheduling resource according to the semi-persistent scheduling resource reconfiguration information.

 Optionally, the first base station sends the semi-persistent scheduling resource reconfiguration information to the second base station, so that the second base station translates the semi-persistent scheduling resource according to the semi-persistent scheduling resource reconfiguration information.

 Optionally, before performing step 01, the first base station needs to coordinate with the second base station, and configure a cooperation mode.

The first base station associates with the semi-persistent scheduling resource configuration information according to the semi-persistent scheduling resource configuration information. The second base station communicates with the user equipment at a semi-persistent scheduling time.

 The cooperation mode includes at least one of the following:

 JT (English full name; Joint processing) joint transmission, DPS (English full name: Dynamic point selection) dynamic transmission point selection, JR (English full name: Joint processing) joint reception.

 Optionally, in the foregoing embodiment, when the DPS is selected for the foregoing cooperative mode, the DPS mode is in different semi-persistent scheduling times, and the first base station performs communication with the user equipment of the second base station to communicate with the user equipment, and the process may be viewed. As a form of flow operation. For example, the series of semi-persistent scheduling times calculated above is expressed as time 1, 2...., and the cells served by the second base station are represented as cell 1, cell 2, . . . , and the expected correspondence is assumed. The sequence is that at the semi-persistent scheduling time 1, the joint cell 1 communicates with the user equipment, and at the semi-persistent scheduling time 2, the joint cell 2 communicates with the user equipment. This description is only a semi-persistent scheduling time and a representation of the cell of the second base station, and has no other special meaning, and the above-mentioned expected corresponding order is only one implementation of the DPS, which is not limited by the embodiment of the present invention. .

Therefore, resource configuration and allocation are not required in each scheduling, signaling and data transmission overhead are reduced, and the capacity and delay requirements of the backhaul link are low.

 Another embodiment of the present invention provides a method for semi-persistent scheduling, which may be performed by a second base station. As shown in FIG. 2, the method includes:

 101. The second base station receives semi-persistent scheduling resource configuration information and semi-persistent scheduling activation information sent by the first base station.
