下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明，但不用来限制本发明的范围。The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
图1是本发明一种实施方式的上行HARQ进程维护方法的流程图；参照图1，所述方法包括：Fig. 1 is a flowchart of an uplink HARQ process maintenance method in an embodiment of the present invention; with reference to Fig. 1, the method includes:
S101：获取本地所配置的制式，根据所述制式确定无线帧中的上行子帧个数及连续数据传输所需的最大进程数，并获取上行共享信道(Physical Uplink Shared Channel，PUSCH)子帧号与上行子帧索引之间的关系表；S101: Obtain the locally configured standard, determine the number of uplink subframes in the wireless frame and the maximum number of processes required for continuous data transmission according to the standard, and obtain the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) subframe number The relationship table with the uplink subframe index;
需要说明的是，由于本方法的执行主体为基站，故而本地所配置的制式即为基站所配置的制式。It should be noted that since the subject of this method is the base station, the system configured locally is the system configured by the base station.
可理解的是，基站所配置的制式可能为FDD或TDD，另外，由于TDD的配比可选择0～6中的任一种，故而，所述制式为TDD时，还需要进一步确定其选择的配比，另外，每种制式所对应的无线帧中的上行子帧个数及连续数据传输所需的最大进程数存在不同，该部分内容可由通信协议确定，属于本领域公知内容，在此不再赘述。It can be understood that the mode configured by the base station may be FDD or TDD. In addition, since the ratio of TDD can be selected from any one of 0 to 6, when the mode is TDD, it is necessary to further determine the selected mode. In addition, the number of uplink subframes in the wireless frame corresponding to each standard and the maximum number of processes required for continuous data transmission are different. This part of the content can be determined by the communication protocol, which belongs to the well-known content in the art, and will not be discussed here. Let me repeat.
S102：在接入的用户设备传输上行数据时，判断所述用户设备是否第一次传输上行数据，若是，则将与所述用户设备对应的计数器清零；S102: When the accessed user equipment transmits uplink data, determine whether the user equipment is transmitting uplink data for the first time, and if so, clear the counter corresponding to the user equipment;
在具体实现中，在本地设有与各用户设备一一对应的计数器，为便于对各计数器的开启和关闭进行控制，故而，本实施方式中，本地还设有与所述计数器分别对应的计数器标志位，在本步骤之前，可将各计数器标志位预先置为FALSE，当然，计数器标志位置为FALSE时，对应的计数器不会启动更新，计数器标志位置为TURE时，对应的计数器启动更新。In a specific implementation, a counter corresponding to each user equipment is provided locally. In order to facilitate the control of the opening and closing of each counter, therefore, in this embodiment, a counter corresponding to the counter is also provided locally. Flag, before this step, each counter flag can be pre-set to FALSE, of course, when the counter flag is FALSE, the corresponding counter will not start updating, and when the counter flag is TRUE, the corresponding counter will start updating.
由于接入的用户设备在接入基站后，有可能在一段时间内均不传输上行数据，故而，本实施方式中，在用户设备是第一次传输上行数据时，需要将与所述用户设备对应的计数器清零，并将与所述计数器对应的计数器标志位置为TURE。Since the accessed user equipment may not transmit uplink data for a period of time after accessing the base station, therefore, in this embodiment, when the user equipment transmits uplink data for the first time, it needs to communicate with the user equipment The corresponding counter is cleared, and the counter flag position corresponding to the counter is set to TRUE.
可理解的是，在用户不是第一次传输上行数据时，可直接执行步骤S103。It can be understood that, when the user is not transmitting uplink data for the first time, step S103 may be directly performed.

S104：判断所述当前上行子帧索引是否代表所述用户设备在所述制式下无线帧的第一个上行子帧，若是，则根据所述计数器、所述无线帧中的上行子帧个数及连续数据传输所需的最大进程数对所述计数器进行更新；S104: Determine whether the current uplink subframe index represents the first uplink subframe of the radio frame of the user equipment under the standard, and if so, according to the counter and the number of uplink subframes in the radio frame and the maximum number of processes required for continuous data transmission to update the counter;
为进一步保证对制式的通用性，本步骤中通过下式对所述计数器进行更新：In order to further ensure the versatility of the system, in this step, the counter is updated by the following formula:
HpCnt＝Mod((HpCnt+UlSubsfnNum)，UlSubsfnNum*MaxHpNum)HpCnt=Mod((HpCnt+UlSubsfnNum), UlSubsfnNum*MaxHpNum)
其中，Mod为取模运算符，HpCnt为计数器的值，U1SubsfnNum为无线帧中上行帧个数，MaxHpNum为连续数据传输所需的最大进程数。Among them, Mod is a modulo operator, HpCnt is the value of the counter, U1SubsfnNum is the number of uplink frames in the wireless frame, and MaxHpNum is the maximum number of processes required for continuous data transmission.
可理解的是，在所述当前上行子帧索引不代表所述用户设备在所述制式下无线帧的第一个上行子帧时，可直接执行步骤S105。It can be understood that, when the current uplink subframe index does not represent the first uplink subframe of the radio frame of the user equipment under the standard, step S105 may be directly executed.
S105：根据所述计数器、当前上行子帧索引及连续数据传输所需的最大进程数确定为所述上行数据分配的HARQ进程的进程号，以实现HARQ进程维护。S105: Determine the process number of the HARQ process allocated for the uplink data according to the counter, the current uplink subframe index and the maximum number of processes required for continuous data transmission, so as to implement HARQ process maintenance.
为进一步保证对制式的通用性，本步骤中通过下式确定为所述上行数据分配的HARQ进程的进程号，In order to further ensure the versatility of the system, in this step, the process number of the HARQ process allocated for the uplink data is determined by the following formula,
HpId＝Mod((UlSubSfnIdx+HpCnt)，MaxHpNum)HpId=Mod((UlSubSfnIdx+HpCnt), MaxHpNum)
其中，HpId为HARQ进程的进程号，Mod为取模运算符，U1SubSfnIdx为当前上行子帧索引，HpCnt为计数器的值，MaxHpNum为连续数据传输所需的最大进程数。Among them, HpId is the process number of the HARQ process, Mod is the modulus operator, U1SubSfnIdx is the current uplink subframe index, HpCnt is the value of the counter, and MaxHpNum is the maximum number of processes required for continuous data transmission.
本实施方式根据本地所配置的制式来确定参数，根据所述参数、与用户设备对应的计数器及上行数据所采用的PUSCH子帧号确定为所述上行数据分配的HARQ进程的进程号，实现了针对FDD和TDD通用的HARQ进程维护，简化了在双模制式下对HARQ进程的维护流程。In this embodiment, the parameters are determined according to the locally configured system, and the process number of the HARQ process allocated for the uplink data is determined according to the parameters, the counter corresponding to the user equipment, and the PUSCH subframe number used by the uplink data, thereby realizing For the common HARQ process maintenance of FDD and TDD, it simplifies the maintenance process of the HARQ process in the dual-mode mode.
