Description

上行传输参数选择方法和设备 Uplink transmission parameter selection method and device

技术领域 Technical field

本发明涉及无线通信技术，尤其涉及一种上行传输参数选择方法和设备。背景技术 The present invention relates to wireless communication technologies, and in particular, to an uplink transmission parameter selection method and device. Background technique

无线通信中，发射机与接收机之间的无线链路条件随着时间的推移而发生变化，在不同的频段上，条件也不相同。链路条件的好坏决定了可以承载的传输数据量，如果链路条件好，则可以传输较多的数据量，而链路条件差则只能传输较低的数据量。针对无线链路的时频变化特性设计了链路自适应技术以提高传输效率。在长期演进（Long Term Evolution, LTE ) ***的上行传输中，链路自适应技术主要包括如下步骤：首先，基站测量得到用户设备（ User Equipment , UE ) 到基站的信号强度（可以由信道系数或信道矩阵表征），以及测量得到干扰水平值和噪声水平值；其次，基站根据信号强度、干扰水平值和噪声水平值调度用户，为用户分配一定的时频资源，并计算出适合当前链路的上行传输参数，上行传输参数包括秩指示（ Rank Indication, RI )、预编码巨阵指示（ Precoding Matrix Indication, PMI ) 、信道质量指示（ Channel Quality Indicator, CQI ) ；再次，基站将分配的时频资源的位置、上行传输参数发送给 UE; 之后， UE根据上行传输参数调制上行数据，并在分配的时频资源位置上发送给基站。 In wireless communication, the radio link conditions between the transmitter and the receiver change over time, and the conditions are different in different frequency bands. The quality of the link conditions determines the amount of data that can be carried. If the link conditions are good, more data can be transmitted, and if the link conditions are poor, only a lower amount of data can be transmitted. Link adaptation techniques are designed to improve transmission efficiency for the time-frequency variation characteristics of wireless links. In the uplink transmission of the Long Term Evolution (LTE) system, the link adaptation technology mainly includes the following steps: First, the base station measures the signal strength of the user equipment (User Equipment, UE) to the base station (may be determined by the channel coefficient or The channel matrix is characterized, and the interference level value and the noise level value are measured. Secondly, the base station schedules the user according to the signal strength, the interference level value and the noise level value, allocates a certain time-frequency resource to the user, and calculates a suitable current link. Uplink transmission parameters, the uplink transmission parameters include a Rank Indication (RI), a Precoding Matrix Indication (PMI), and a Channel Quality Indicator (CQI); again, the time-frequency resource to be allocated by the base station The location, the uplink transmission parameter is sent to the UE; after that, the UE modulates the uplink data according to the uplink transmission parameter, and sends the uplink data to the base station at the allocated time-frequency resource location.

上述的信号强度、噪声水平值随时间的变化很小，而干扰水平值可能随时间变化很大。从上述描述可以看出，上行传输参数是根据调度时间测量的干扰水平值等选择得到的，但是，调度时间和 UE实际上传数据的时间是存在延时的，两个时间的链路质量是不同的，尤其是异构网络中由于存在强干扰，两个时间上的干扰水平值存在较大差异，那么在调度时间选择的上行传输参数就是不合适的，影响上行传输性能。发明内容本发明实施例提供一种上行传输参数选择方法和设备，用以选择更合适的上行传输参数，提高上行传输性能。 The above signal strength and noise level values change little with time, and the interference level values may vary greatly with time. As can be seen from the above description, the uplink transmission parameter is selected according to the interference level value measured by the scheduling time, etc., but the scheduling time and the time when the UE actually uploads the data are delayed, and the link quality of the two times is different. In particular, in the heterogeneous network, due to the strong interference, the interference level values of the two times have large differences, then the uplink transmission parameters selected at the scheduling time are inappropriate, which affects the uplink transmission performance. Summary of the invention The embodiment of the invention provides a method and a device for selecting an uplink transmission parameter, which are used to select a more suitable uplink transmission parameter and improve uplink transmission performance.

BRIEF DESCRIPTION OF THE DRAWINGS In order to more clearly illustrate the technical solutions in the embodiments of the present invention, a brief description of the drawings to be used in the description of the embodiments will be briefly made.

其中，基站可以测量得到 UE到基站的信号强度，并且也可以测量得到调度时的干扰水平值 interference level和噪声水平值 noise level;之后，基站就可以根据信号强度、 interference level和 noise level估计用户与基站间的信道质量，并据此为用户分配一定的时频资源。分配的时频资源可以用物理资源块（ Physical Resource Block, PRB )表示。因此，基站在调度时可以确定为 UE分配哪些 PRB。 The base station can measure the signal strength of the UE to the base station, and can also measure the interference level value and the noise level value of the scheduling level. After that, the base station can estimate the user according to the signal strength, the interference level, and the noise level. The channel quality between the base stations, and according to this, allocates certain time-frequency resources to the users. The allocated time-frequency resources can be represented by a Physical Resource Block (PRB). Therefore, the base station can determine which PRBs are allocated to the UE when scheduling.

一个基站的调度情况包括该基站为其所服务的至少一个 UE分配的用于通信的资源。相邻的基站之间可以通过交互获取对方的调度情况，例如通过 X2接口获取相邻基站将哪些 PRB分配给了哪些 UE使用。 The scheduling situation of a base station includes resources allocated by the base station for communication for at least one UE served by the base station. The neighboring base stations can obtain the scheduling of the other party through interaction, for example, through the X2 interface, which PRBs are allocated to which UEs are used by the neighboring base stations.

步骤 12: 该基站根据所述调度情况，确定第一干扰水平值，所述第一干扰水平值为第一 UE在上行数据传输时受到的来自第二 UE的干扰水平值，所述第一 UE为本基站服务的 UE, 所述第二 UE为所述相邻基站服务的 UE; Step 12: The base station determines, according to the scheduling situation, a first interference level value, where the first interference level value is an interference level value received by the first UE from the second UE when the uplink data is transmitted, the first UE a UE serving the base station, where the second UE is a UE served by the neighboring base station;

首先，基站可以根据相邻基站的调度情况，确定本小区 UE 的干扰用户，其中，用户也可以称为 UE; 例如，参见图 2, 包括两个基站和三个用户，分别为基站 1、基站 2以及用户 1、用户 2和用户 3 , 用户 1为基站 1 服务的用户，用户 2和用户 3为基站 2服务的用户。假设基站 1分配给用户 1的时频资源为 PRB 1 ,并且基站 2分配给用户 2的时频资源也是 PRB 1 , 那么对于用户 1来讲，用户 2就是干扰用户。 First, the base station may determine the interfering user of the UE in the cell according to the scheduling situation of the neighboring base station, where the user may also be referred to as the UE; for example, referring to FIG. 2, including two base stations and three users, respectively, the base station 1 and the base station 2 and user 1, user 2 and user 3, user 1 is a user serving base station 1, user 2 and user 3 are users serving base station 2. Assuming that the time-frequency resource allocated by the base station 1 to the user 1 is PRB 1 and the time-frequency resource allocated by the base station 2 to the user 2 is also PRB 1, then for the user 1, the user 2 is the interfering user.

其次，在确定干扰用户后，可以通过对干扰用户的监测值得到干扰水平值，其中，干扰用户的监测值可以是预先已经监测得到的；例如，基站实时监测来自每个用户的测量参考信号（ Sounding Reference Signal, SRS ), 进行信号强度测量并进行记录，在确定出干扰用户后，就将根据其对应的 SRS测量得到的信号强度值确定为干扰水平值。第一干扰水平值是在所述基站未调度第一 UE时监测得到的第二 UE对第一 UE的干扰水平，可以是基站在对第一 UE调度完成后实时监测得到的第二 UE对第一 UE的干扰水平值。在未进行调度第一 UE时，基站也可检测得到第一干扰水平值，并将该第一干扰水平值作为 UE上行数据传输时受到的来自第二 UE的干扰水平值。 Secondly, after determining the interfering user, the interference level value can be obtained by monitoring the value of the interfering user, wherein the monitoring value of the interfering user can be monitored in advance; for example, the base station monitors the measurement reference signal from each user in real time ( Sounding Reference Signal, SRS), performs signal strength measurement and records. After determining the interference user, the signal strength value measured according to the corresponding SRS is determined as the interference level value. The first interference level value is an interference level of the second UE that is monitored by the second UE when the base station does not schedule the first UE, and may The interference level value of the second UE to the first UE that is monitored by the base station in real time after the scheduling of the first UE is completed. When the first UE is not scheduled, the base station may also detect the first interference level value, and use the first interference level value as the interference level value received by the second UE when the UE uplink data is transmitted.

步骤 13: 该基站根据所述本基站检测到的来自所述第一 UE的信号强度、所述本基站的噪声水平值和所述第一干扰水平值，确定第一上行传输参数； Step 13: The base station determines, according to the signal strength from the first UE, the noise level value of the local base station, and the first interference level value detected by the local base station, a first uplink transmission parameter.

其中，基站可以通过信号检测，得到该基站服务的 UE发送的信号在到达基站时的信号强度，即得到本基站检测到的来自所述第一 UE的信号强度；另外，基站也可以通过检测得到基站内器件产生的噪声水平值，即得到本基站的噪声水平值；与现有技术不同的时，本发明实施例在计算上行传输参数，即在计算 RI、 PMI、 CQI等信息时，釆用的干扰水平值不是调度时的干扰水平值，例如，参见图 2, 在调度时基站 2可能是调度用户 The base station can obtain the signal strength of the signal sent by the UE served by the base station when it arrives at the base station, that is, obtain the signal strength from the first UE detected by the base station; in addition, the base station can also obtain the signal strength from the first UE. The noise level value generated by the device in the base station is obtained as the noise level value of the base station; when different from the prior art, the embodiment of the present invention calculates the uplink transmission parameter, that is, when calculating information such as RI, PMI, CQI, etc. The interference level value is not the interference level value at the time of scheduling. For example, referring to FIG. 2, the base station 2 may be a scheduling user at the time of scheduling.

3而不是用户 2, 那么根据调度时的干扰水平值则具体是根据用户 3对应的信号强度值。由于本基站调度第一 UE时的干扰与第一 UE在实际上行传输数据时的干扰可能存在较大差异，本实施例根据第一 UE在上行传输数据时的干扰水平值选择上行传输参数将更为准确。 3, instead of user 2, then the interference level value according to the schedule is specifically based on the signal strength value corresponding to user 3. The interference of the first UE when scheduling the first UE may be different from the interference of the first UE when actually transmitting data. In this embodiment, the uplink transmission parameter is selected according to the interference level value of the first UE when transmitting data in the uplink. To be accurate.

可以理解的是，由于信号强度、噪声水平值随时间变化较小，其依然可以选择调度时测量得到的信号强度和噪声水平值。 It can be understood that since the signal strength and the noise level value change little with time, it is still possible to select the signal strength and noise level value measured at the time of scheduling.

步骤 14: 该基站向所述第一 UE发送下行控制信令，以指示所述第一 Step 14: The base station sends downlink control signaling to the first UE to indicate the first

UE在上行数据传输时传输与所述第一上行传输参数对应的上行数据。 The UE transmits uplink data corresponding to the first uplink transmission parameter during uplink data transmission.

该下行控制信令中可以包含第一上行传输参数，此时， UE可以釆用该第一上行传输参数对原始数据进行数据生成后得到对应的上行数据后发送；或者，该下行控制信令中可以包含指示信息，用于指示 UE上传与第一上行传输参数对应的数据块， UE在此之前已经生成了多种数据块，以便 UE传输与第一上行传输参数对应的数据块。具体内容可以参见下述实施例。 The downlink control signaling may include the first uplink transmission parameter. In this case, the UE may use the first uplink transmission parameter to generate data corresponding to the original data, and then send the corresponding uplink data, and then send the downlink control signaling. The indication information may be included for instructing the UE to upload a data block corresponding to the first uplink transmission parameter, and the UE has previously generated a plurality of data blocks, so that the UE transmits the data block corresponding to the first uplink transmission parameter. For details, see the following embodiments.

相应的，参见图 3 , UE侧执行的流程可以包括： Correspondingly, referring to FIG. 3, the process performed by the UE side may include:

步骤 31 : 第一 UE接收基站发送的下行控制信令； Step 31: The first UE receives downlink control signaling sent by the base station.

其中，第一 UE为该基站服务的 UE。步骤 32: 第一 UE根据所述下行控制信令确定第一上行传输参数对应的数据，所述第一上行传输参数是根据所述基站检测到的来自第一 UE的信号强度、所述基站的噪声水平值和第一干扰水平值确定的，所述第一干扰水平值为所述第一 UE在上行数据传输时受到的来自第二 UE的干扰水平值，所述第一 UE为所述基站服务的 UE, 所述第二 UE为所述基站的相邻基站服务的 UE; The first UE is a UE served by the base station. Step 32: The first UE determines, according to the downlink control signaling, data corresponding to the first uplink transmission parameter, where the first uplink transmission parameter is based on a signal strength detected by the base station from the first UE, and the base station Determining, by the noise level value and the first interference level value, the first interference level value is an interference level value received by the first UE from the second UE when the uplink data is transmitted, where the first UE is the base station a serving UE, where the second UE is a UE served by a neighboring base station of the base station;

步骤 33: 第一 UE在上行数据传输时，向所述基站发送所述第一上行传输参数对应的数据。 Step 33: The first UE sends data corresponding to the first uplink transmission parameter to the base station during uplink data transmission.

可选的，如果所述下行控制信令中包含第一上行传输参数，则第一 UE釆用所述第一上行传输参数对原始数据进行数据生成，得到所述第一上行传输参数对应的上行数据，数据生成例如包括循环校验 Optionally, if the downlink control signaling includes the first uplink transmission parameter, the first UE performs data generation on the original data by using the first uplink transmission parameter, and obtains an uplink corresponding to the first uplink transmission parameter. Data, data generation, for example, including loop check

( Cyclic Redundancy Check, CRC ) 、码块切分、信道编码、速率匹配以及调制等；或者，如果所述下行控制信令中包含指示信息，则第一 UE接收基站发送的指示信息，根据所述指示信息从所述至少两个的数据块中确定所述第一上行传输参数对应的数据，此时，第一 UE预先已经根据基站发送的至少两组的上传传输参数组合生成至少两个的数据块。 (Cyclic Redundancy Check, CRC), code block segmentation, channel coding, rate matching, and modulation, etc.; or, if the downlink control signaling includes indication information, the first UE receives the indication information sent by the base station, according to the The indication information is used to determine data corresponding to the first uplink transmission parameter from the at least two data blocks. At this time, the first UE has previously generated at least two data according to at least two sets of upload transmission parameter combinations sent by the base station. Piece.

可选的，下行控制信令可以釆用组标识进行加扰，第一 UE在预先设定的子帧上接收下行控制信令并釆用预先确定的组标识进行解扰，得到第一 UE对应的第一上行传输参数或者指示信息。 Optionally, the downlink control signaling may be scrambled by using the group identifier, and the first UE receives the downlink control signaling in the preset subframe and performs descrambling by using the predetermined group identifier to obtain the first UE corresponding. The first uplink transmission parameter or indication information.

本实施例根据 UE在上行数据传输时的干扰水平值确定第一上行传输参数，并釆用第一上行传输参数传输数据，由于上行传输参数就是根据上行数据传输时的干扰确定的，而不是调度时的干扰，那么就不存在调度与实际传输数据时的延时问题，可以选择更合适的上行传输参数，提高上行传输性能。 In this embodiment, the first uplink transmission parameter is determined according to the interference level value of the UE during uplink data transmission, and the first uplink transmission parameter is used to transmit data, because the uplink transmission parameter is determined according to interference during uplink data transmission, instead of scheduling. Interference, then there is no delay problem when scheduling and actually transmitting data, and more suitable uplink transmission parameters can be selected to improve uplink transmission performance.

图 4为本发明上行传输参数选择方法另一实施例的流程示意图，包括：步骤 41 : 基站在调度 UE时，为 UE分配时频资源以及确定第二上行传输参数。 4 is a schematic flowchart of another embodiment of an uplink transmission parameter selection method according to the present invention, including: Step 41: When scheduling a UE, the base station allocates time-frequency resources for the UE and determines a second uplink transmission parameter.

其中，如上所述，基站可以根据信号强度、干扰水平值、噪声水平值为 UE分配时频资源。 As described above, the base station may allocate time-frequency resources to the UE according to the signal strength, the interference level value, and the noise level value.

第二上行传输参数与第一上行传输参数不同的是，第二上行传输参数依据的干扰水平值是调度时的干扰水平值，而第一上行传输参数是基于上行数据传输时的干扰水平值。调度时的干扰水平值为第二干扰水平值，可以是基站在调度 UE的时候下发给所述 UE的。上行数据传输时的干扰水平值是第一干扰水平值，可以是基站在未进行调度时检测得到的干扰水平值，如实时监测其他 UE对所述 UE的干扰情况得到的干扰水平值。 The second uplink transmission parameter is different from the first uplink transmission parameter, and the second uplink transmission parameter is The interference level value according to is the interference level value at the time of scheduling, and the first uplink transmission parameter is based on the interference level value at the time of uplink data transmission. The interference level value at the time of scheduling is a second interference level value, which may be sent by the base station to the UE when scheduling the UE. The interference level value in the uplink data transmission is the first interference level value, which may be the interference level value detected by the base station when not scheduled, such as the interference level value obtained by monitoring the interference situation of other UEs to the UE in real time.

步骤 42: 基站将第二上行传输参数携带在上行调度命令（UL grant ) 中发送给 UE。 Step 42: The base station sends the second uplink transmission parameter to the UE in an uplink scheduling command (UL grant).

步骤 43: 基站获取相邻基站的调度情况，并根据调度情况确定第一上行传输参数。 Step 43: The base station acquires a scheduling situation of the neighboring base station, and determines a first uplink transmission parameter according to the scheduling situation.

确定第一上行传输参数的流程可以具体参见上一实施例。 The process of determining the first uplink transmission parameter may be specifically referred to the previous embodiment.

步骤 44: 基站将第一上行传输参数携带在调整信令中发送给 UE。其中，上述的 UL grant和调整信令都可以为下行控制信令（ Downlink Control Information, DCI ) , 具体可以釆用 DCI format4。 Step 44: The base station carries the first uplink transmission parameter in the adjustment signaling and sends the signal to the UE. The foregoing UL grant and the adjustment signaling may be Downlink Control Information (DCI), and the DCI format4 may be specifically used.

UE接收到调整信令后，将进行上行传输参数调整，从第二上行传输参数调整为第一上行传输参数。 After receiving the adjustment signaling, the UE performs uplink transmission parameter adjustment, and adjusts the second uplink transmission parameter to the first uplink transmission parameter.

步骤 45: UE在上行数据传输时，根据第一上行传输参数传输上行数据。 Step 45: The UE transmits uplink data according to the first uplink transmission parameter during uplink data transmission.

需要说明的是，本实施例以基站先向 UE发送一次上行传输参数，之后再调整上行传输参数为例。可选的，基站也可以只向 UE发送一次调整后的上行传输参数，也就是基站在调度时不向 UE发送第二上行传输参数，而是在确定出第一上行传输参数时才将第一上行传输参数发送给 UE。 It should be noted that, in this embodiment, the base station first sends an uplink transmission parameter to the UE, and then adjusts the uplink transmission parameter as an example. Optionally, the base station may send only the adjusted uplink transmission parameter to the UE, that is, the base station does not send the second uplink transmission parameter to the UE when scheduling, but only when determining the first uplink transmission parameter. The uplink transmission parameters are sent to the UE.

本实施例通过调整上行传输参数，可以使得 UE釆用更为合适的上行传输参数传输上行数据，提高上行传输性能。 In this embodiment, by adjusting the uplink transmission parameters, the UE may use the more suitable uplink transmission parameters to transmit uplink data, thereby improving uplink transmission performance.

图 5为本发明上行传输参数选择方法另一实施例的流程示意图，包括：步骤 51 : 基站在调度 UE时，为 UE分配时频资源以及确定多组上行传输参数组合。 FIG. 5 is a schematic flowchart of another embodiment of an uplink transmission parameter selection method according to the present invention, including: Step 51: When scheduling a UE, the base station allocates time-frequency resources for the UE and determines multiple sets of uplink transmission parameter combinations.

与上一实施例不同的是，上一实施例是根据调度时的干扰水平值确定出一组上行参数组合 ( RI/PMI/CQI ) ；而本实施例为每个 UE确定多组 RI/PMI/CQI, 例如 RI1/PMI1/CQI1以及 RI2/PMI2/CQI2。其中，多组上行参数组合可以根据多种可能的干扰水平值确定出的，例如，在图 2所示的场景下，基站 1可以分别确定当干扰为用户 2时对应的组合 Different from the previous embodiment, the previous embodiment determines a set of uplink parameter combinations (RI/PMI/CQI) according to the interference level value at the time of scheduling; and this embodiment determines multiple sets of RI/PMI for each UE. /CQI, such as RI1/PMI1/CQI1 and RI2/PMI2/CQI2. Wherein, multiple sets of uplink parameter combinations may be determined according to various possible interference level values, for example, as shown in FIG. In the scenario, the base station 1 can determine the corresponding combination when the interference is the user 2, respectively.

RI1/PMI1/CQI1 , 以及干扰为用户 3时对应的组合 RI2/PMI2/CQI2。 RI1/PMI1/CQI1, and the combination RI2/PMI2/CQI2 corresponding to the interference of user 3.

步骤 52: 基站将多组上行传输参数组合携带在上行调度命令（UL grant ) 中发送给 UE。 Step 52: The base station sends multiple sets of uplink transmission parameters in the uplink scheduling command (UL grant) to the UE.

步骤 53: UE根据上行传输参数组合分别生成多个数据块。 Step 53: The UE separately generates a plurality of data blocks according to the uplink transmission parameter combination.

例如，根据原始数据和 RI1/PMI1/CQI1生成数据块 1 , 以及根据原始数据和 RI2/PMI2/CQI2生成数据块 2。 For example, data block 1 is generated based on the original data and RI1/PMI1/CQI1, and data block 2 is generated based on the original data and RI2/PMI2/CQI2.

步骤 54: 基站获取相邻基站的调度情况，并根据调度情况确定第一上行传输参数。 Step 54: The base station acquires a scheduling situation of the neighboring base station, and determines a first uplink transmission parameter according to the scheduling situation.

步骤 55: 基站向 UE发送调整信令，其中携带指示信息，该指示信息用于指示 UE选择与第一上行传输参数对应的数据块。 Step 55: The base station sends the adjustment signaling to the UE, where the indication information is used to indicate that the UE selects a data block corresponding to the first uplink transmission parameter.

例如，第一上行传输参数包括 RI1/PMI1/CQI1 , 则指示信息指示选择数据块 1。 For example, if the first uplink transmission parameter includes RI1/PMI1/CQI1, the indication information indicates that the data block 1 is selected.

另外，需要说明的是，步骤 51时确定的参数组合并不一定包含第一上行传输参数，那么与第一上行传输参数对应的数据块是指根据最接近第一上行传输参数的参数生成的数据块。例如，预先确定的多个组合中不包含 RI1/PMI1/CQI1 , 而预先确定的组合中 RI2/PMI2/CQI2是最接近 In addition, it should be noted that the parameter combination determined in step 51 does not necessarily include the first uplink transmission parameter, and the data block corresponding to the first uplink transmission parameter refers to the data generated according to the parameter that is closest to the first uplink transmission parameter. Piece. For example, RI1/PMI1/CQI1 is not included in a predetermined combination, and RI2/PMI2/CQI2 is the closest in a predetermined combination.

RI1/PMI1/CQI1的，那么指示信息可以指示根据 RI2/PMI2/CQI2生成的数据块。 For RI1/PMI1/CQI1, the indication information may indicate the data block generated from RI2/PMI2/CQI2.

再者，指示信息也不限于指示一个数据块，也可以指示多个数据块，例如，指示根据较接近第一上行传输参数的设定个数的上行传输参数生成的数据块。 Furthermore, the indication information is not limited to indicating one data block, and may also indicate a plurality of data blocks, for example, a data block generated according to a set number of uplink transmission parameters that are closer to the first uplink transmission parameter.

步骤 56: UE在上行数据传输时，传输指示信息指示的数据块。 Step 56: The UE transmits the data block indicated by the indication information during uplink data transmission.

本实施例通过调整上行传输参数，可以使得 UE传输更为合适的上行传输参数对应的上行数据，提高上行传输性。 In this embodiment, by adjusting the uplink transmission parameter, the UE can transmit the uplink data corresponding to the more suitable uplink transmission parameter, and improve the uplink transmission performance.

在实施时，图 4或图 5所示的实施例的调整信令可以釆用 UE id进行加扰，那么 UE接收到下行控制信令时釆用自身的 UE id进行解扰以获取第一上行传输参数或者指示信息。也就是说，上述实施例以逐个向 UE发送第一上行传输参数或指示信息为例，可选的，也可以釆用群组的方式发送。图 6为本发明上行传输参数选择方法另一实施例的流程示意图，包括：步骤 61 : 基站发送下行控制信令，该下行控制信令釆用组标识进行加扰。 In the implementation, the adjustment signaling of the embodiment shown in FIG. 4 or FIG. 5 may be scrambled by using the UE id, and then, when receiving the downlink control signaling, the UE performs descrambling with its own UE id to obtain the first uplink. Transfer parameters or indications. That is to say, the foregoing embodiment is used to send the first uplink transmission parameter or the indication information to the UE one by one, and may also be sent by using a group. FIG. 6 is a schematic flowchart of another embodiment of an uplink transmission parameter selection method according to the present invention, including: Step 61: A base station sends downlink control signaling, where the downlink control signaling uses a group identifier to perform scrambling.

其中，下行控制信令中包含多个 UE对应的第一上行传输参数或者指示信息。 The downlink control signaling includes a first uplink transmission parameter or indication information corresponding to multiple UEs.

另外，与上述实施例釆用 UE id加扰不同的是，本实施例的下行控制信令釆用组标识（ group id ) 加扰。 In addition, unlike the above embodiment, UE id scrambling is used, and the downlink control signaling of this embodiment is scrambled with a group identifier (group id).

组标识可以为调度子帧的子帧号的函数，例如，在子帧 n被调度的 UE, 其所属的组标识为 f(n), f(n)的具体形式可以设定。或者，组标识也可以是由基站单独通知给每个 UE。 The group identifier may be a function of the subframe number of the scheduling subframe. For example, the UE that is scheduled in the subframe n may belong to the group identifier f(n), and the specific form of f(n) may be set. Alternatively, the group identity may also be separately notified to each UE by the base station.

对于每个 UE, 其对应下行控制信令在组内的位置，可以同第二上行传输参数一起发送给 UE。 For each UE, the location of the corresponding downlink control signaling in the group may be sent to the UE together with the second uplink transmission parameter.

步骤 62: UE接收下行控制信令并釆用组标识解扰，得到第一上行传输参数或者指示信息。 Step 62: The UE receives the downlink control signaling and uses the group identifier to descramble to obtain the first uplink transmission parameter or the indication information.

UE可以在预先设定的子帧上接收下行控制信令，例如，基站在子帧 n 时调度 UE, UE在子帧 n+4时传输上行数据，那么可以预先设定在子帧 n+2时传输该下行控制信令。那么，所有的 UE就可以在子帧 n+2时接收下行控制信令并釆用自身的组标识进行解扰，如果能够成功解扰表明包含自身的信息，并获取自身的信息，如第一上行传输参数或者指示信息。 The UE may receive downlink control signaling in a preset subframe. For example, the base station schedules the UE in the subframe n, and the UE transmits the uplink data in the subframe n+4, and may be preset in the subframe n+2. The downlink control signaling is transmitted. Then, all UEs can receive downlink control signaling in subframe n+2 and use its own group identifier to descramble. If it can successfully descramble, it indicates that it contains its own information, and obtains its own information, such as the first. Uplink transmission parameters or indication information.

另外，本实施例中的下行控制信令中包含多个 UE对应的信息，那么可以预先设定每个 UE对应的信息所在的位置。例如，一个组中包含 3个 UE的信息，每个信息占用两个比特，那么可以预先设定标识号最小的 UE1 对应的信息位于前两个比特，标识号处于中间的 UE2对应的信息位于中间两个比特，标识号最大的 UE3对应的信息位于最后两个比特。 In addition, the downlink control signaling in this embodiment includes information corresponding to multiple UEs, and the location of the information corresponding to each UE may be preset. For example, if a group contains information of three UEs, each of which occupies two bits, the information corresponding to UE1 with the smallest identification number is located in the first two bits, and the information corresponding to UE2 with the identification number in the middle is located in the middle. Two bits, the information corresponding to the UE3 with the largest identification number, is located in the last two bits.

步骤 63: UE在上行数据传输时，向基站传输与第一上行传输参数对应的数据块。 Step 63: The UE transmits a data block corresponding to the first uplink transmission parameter to the base station during uplink data transmission.

得到第一上行传输参数或者指示信息后的流程可以具体参见图 4或图 5所示的实施例。 The flow after obtaining the first uplink transmission parameter or indication information may be specifically referred to the embodiment shown in FIG. 4 or FIG. 5.

在上述实施例的基础上，本实施例通过组标识将多个 UE的信息一起传输，还可以降低传输开销。图 7为本发明上行传输参数选择设备一实施例的结构示意图，该设备位于基站侧，包括获取模块 71、第一确定模块 72、第二确定模块 73和发送模块 74; 获取模块 71用于获取相邻基站的调度情况；第一确定模块 72 用于根据所述调度情况，确定第一干扰水平值，所述第一干扰水平值为第 ― UE在上行数据传输时受到的来自第二 UE的干扰水平值，所述第一 UE 为本基站服务的 UE, 所述第二 UE为所述相邻基站服务的 UE; 第二确定模块 73用于根据所述本基站检测到的来自所述第一 UE的信号强度、所述本基站的噪声水平值和所述第一干扰水平值，确定第一上行传输参数；发送模块 74用于向所述第一 UE发送下行控制信令，以指示所述第一 UE在上行数据传输时传输与所述第一上行传输参数对应的上行数据。 On the basis of the foregoing embodiment, the embodiment transmits the information of multiple UEs together by using the group identifier, and the transmission overhead can also be reduced.
