Description

Base station, user terminal, and data transmission method

Technical field

The present invention relates to the field of communications, and in particular, to a base station, a user terminal, and a data transmission method.

Background technique

In wireless communication, the time-frequency resources used by the user terminal (English: User Equipment, abbreviated as UE) to communicate with the base station are generally scheduled by the base station. In the Long Term Evolution (LTE) system, the uplink and downlink data scheduling of the base station is implemented by a physical downlink control channel (English: Physical Downlink Control Channel, abbreviated as PDCCH).

Taking the control channel element (English: Control Channel Element, abbreviated as CCE) of the PDCCH signaling as an example, the downlink control channel of the system supports up to 44 PDCCH signaling under the condition that the LTE system bandwidth is 20 MHz. Considering that each UE needs both uplink scheduling and downlink scheduling, the downlink control channel of the system can only support the scheduling of 22 UEs. When the number of UEs connecting to the base station is large, the scheduling capability of the base station is insufficient, resulting in the UE and the base station. The delay between the two is high, which affects the communication performance of the system.

detailed description

The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

Please refer to FIG. 1, which shows an architectural diagram of a network environment in which the present invention relates. The network includes the following network devices: a base station 110 and at least one user terminal 120.

In the embodiment of the present invention, when the user terminal 120 accesses the base station 110, the base station 110 may pre-allocate the user terminal 120 with the unscheduled resource used for transmitting data without scheduling the base station, and negotiate with the user terminal 120. The identity sequence, when the user terminal 120 transmits data to the base station 110, may directly use the unscheduled resources and the pre-allocation allocated by the base station 110 without scheduling by the base station 110. The identity sequence performs unscheduled transmission. When the base station 110 detects the data carried by the unscheduled resource, the base station 110 distinguishes the user terminal that sends the data by parsing the identity sequence contained therein.

In the above solution, the unscheduled resource is allocated to the user terminal 120 by the base station 110 in advance. The user terminal 120 does not need to perform scheduling by the base station 110 when transmitting data, and directly uses the unscheduled resource for data transmission, which can reduce a large amount of data. Signaling interaction effectively reduces the delay of data transmission between the base station and the user terminal.

Referring to FIG. 2, a flow chart of a method for data transmission according to an embodiment of the present invention is shown. The data transmission method can be used in the base station 110 of the implementation environment shown in FIG. The data transmission method can include:

Step 201: The base station allocates an unscheduled resource to the user terminal, and sends a resource configuration message for indicating the unscheduled resource to the user terminal, where the unscheduled resource includes n resource blocks, n≥1.

The schedule-free resource is a resource used by the user terminal to transmit data without being scheduled by the base station.

Step 202: The base station negotiates with the user terminal to generate an identity sequence of the user terminal.

Step 203: When the base station detects the data carried by the specified resource block, the base station extracts an identity identification sequence, where the specified resource block is one of the at least one resource block.

Step 204: The base station calculates a matching value between the extracted identity sequence and the identity sequence, and detects whether the matching value is greater than a first threshold.

Step 205: If the detection result is that the matching value is greater than the first threshold, the base station determines the data as data sent by the user terminal.

In summary, in the data transmission method provided by the embodiment of the present invention, the base station allocates the scheduling-free resource to the user terminal, and negotiates the identity sequence with the user terminal. When the user terminal sends the data subsequently, the base station may directly use the unscheduled resource to send the identity sequence. Data, when detecting the data carried by the specified resource block, the base station identifies the user terminal that sends the data according to the identity sequence in the data, and the data transmission process does not require the base station to perform resource scheduling signaling, thereby reducing a large number of signaling interactions. , effectively reducing the delay of data transmission between the base station and the user terminal.

Please refer to FIG. 3, which is a flowchart of a method for data transmission according to an embodiment of the present invention. The data transmission method can be used in the user terminal 120 of the implementation environment shown in FIG. The data transmission method can include:

Step 301: The user terminal receives a resource configuration message sent by the base station, and configures an unscheduled resource according to the resource configuration message, where the unscheduled resource includes n resource blocks, n≥1.

The unscheduled resource is a resource used by the user terminal to transmit data without being scheduled by the base station.

Step 302: The user terminal negotiates with the base station to generate an identity sequence of the user terminal.

Step 303: The user terminal selects one resource block from the n resource blocks as a designated resource block, and sends data including the identity sequence to the base station by using the specified resource block, so that the base station extracts an identity recognition sequence from the data. And calculating a matching value between the extracted identity sequence and the identity sequence, and determining, when the matching value is greater than the first threshold, determining the data as data sent by the user terminal.

In summary, the data transmission method provided by the embodiment of the present invention, the user terminal receives the resource configuration information sent by the base station, configures the scheduling-free resource, and negotiates the identity sequence with the base station. When the user terminal subsequently sends data, the user terminal can directly send the unscheduled resource. The data including the identity sequence, when detecting the data carried by the specified resource block, the base station identifies the user terminal that sends the data according to the identity sequence in the data, and the data transmission process does not require the base station to perform resource scheduling signaling, which is reduced a large amount. The signaling interaction effectively reduces the delay of data transmission between the base station and the user terminal.

Referring to FIG. 4A, a flowchart of a method for data transmission according to an embodiment of the present invention is shown. This data transmission method can be used in the implementation environment shown in FIG. The data transmission method can include:

In step 401, the user terminal accesses the base station.

Step 402: The base station allocates an unscheduled resource to the user terminal, and sends a resource configuration message for indicating the unscheduled resource to the user terminal, where the unscheduled resource includes n resource blocks, n≥1.

The resource block is used to indicate a time-frequency resource, and the size of each resource block may be the same or different. For example, in an LTE system, each resource block may be configured to have the same size, and each resource block has a size of 1 subframe×24 subcarriers.

The base station may allocate a part of the available time-frequency resources as an unscheduled resource allocated to each user terminal of the access base station. Specifically, when dividing the unscheduled resource, the base station may collect data transmission status information for a period of time before the current time, where the data transmission status information may include an access base. The total number of user terminals of the station, the total traffic of data transmitted between the base station and each user terminal, and the quality of service required by the data transmitted between the base station and each user terminal (English: Quality of Service, abbreviation: QoS). The base station determines, according to the statistical data transmission state information, the ratio of the unscheduled resource to all available time-frequency resources. Specifically, the ratio is proportional to the total number of user terminals of the access base station, and between the base station and each user terminal. The total traffic of the transmitted data is inversely proportional to the inverse of the quality of service required by the data transmitted between the base station and each user terminal; that is, the greater the total number of user terminals accessing the base station, the transmission between the base station and each user terminal The smaller the total data traffic, the lower the quality of service required for data transmitted between the base station and each user terminal, and the higher the proportion of the non-scheduled resources to all available time-frequency resources, and vice versa. In addition, the base station may also set an upper limit for the proportion of the unscheduled resources to all available time-frequency resources. For example, when the upper limit is 40%, the base station can only divide up to 40% of all available time-frequency resources. Schedulable resources.

When the user terminal accesses the base station, the base station allocates a fixed-size unscheduled resource to the user terminal. For example, initially allocates two resource blocks as the unscheduled resource, and sends a resource configuration message to the user terminal, where the resource configuration message is used. Indicates a non-scheduled resource allocated to the user terminal, for example, a resource block number of the unscheduled resource, or a time domain and a frequency band of the unscheduled resource.

Step 403: The user terminal configures an unscheduled resource according to the resource configuration message.

After receiving the resource configuration message sent by the base station, the user equipment configures the time-frequency resource indicated by the resource configuration message as a non-scheduled resource.

Step 404: The base station negotiates with the user terminal to generate an identity sequence of the user terminal.

The base station negotiates with the user terminal to generate a demodulation reference signal DMRS sequence based on the identifier of the user terminal; or the base station negotiates with the user terminal to generate a DMRS sequence based on the feature information of the cell where the user terminal is located, and the feature information of the cell The identifier of the cell or a pseudo-random sequence pre-assigned by the base station to the cell is included.

For example, the base station may obtain the identifier of the user terminal, and calculate, according to the identifier of the user terminal and the preset first algorithm, a demodulation reference signal (English: De Modulation Reference Signal, DMRS) sequence of the user terminal, the DMRS The sequence is a sequence obtained by cyclically shifting the DMRS root sequence, and the base station may directly send the DMRS sequence to the user terminal, or may send the DMRS root sequence and the cyclic shift to the user terminal, and the user terminal according to the cyclic shift The DMRS root sequence is cycled to obtain the DMRS sequence. The identifier of the user terminal may be the ID of the user terminal or the cell radio network temporary identifier of the cell where the user terminal is located (English: Cell Radio Network Temporary Identifier, abbreviated as C-RNTI).

Alternatively, the base station may also send the feature information transmitted by the base station to the user terminal, and the user terminal may generate the identity sequence according to the feature information and the second algorithm, and the user terminal may send the generated identity sequence to the base station, or may be The feature information and the second algorithm generate an identity sequence of the user terminal. The feature information may be an identifier of the cell (such as a cell ID) or a pseudo random sequence pre-allocated by the base station to the cell.

In a conventional wireless communication system, DMRS is used for correlation demodulation of a data channel, and in the solution shown in the embodiment of the present invention, the DMRS is used for transmitting data in addition to correlation demodulation for a data channel. The user terminal performs identity recognition, and does not need to additionally add information for identity identification in the transmitted data, thereby saving transmission resources and improving system performance.

Step 405: The user terminal selects one resource block from the n resource blocks as the designated resource block, and sends data including the identity sequence to the base station by using the specified resource block.

When the number of user terminals accessing the base station is large, the scheduling resources of some user terminals may be the same. If the user terminal selects a specified resource block for sending data from the unscheduled resource through an ordered policy, then multiple user terminals are used. When the scheduling resources are the same, once the specified resource blocks selected by the multiple user terminals collide, the subsequent multiple user terminals will always select the same specified resource block for transmission, thereby causing the data transmission of some of the user terminals to fail. , affecting the transmission performance of the system. In this regard, in the method shown in the embodiment of the present invention, when selecting a specified resource block for transmitting data, the user terminal randomly selects one resource block from the n resource blocks included in the unscheduled resource for transmission, when multiple user terminals are exempted When the scheduling resources are the same, even if the plurality of user terminals select the same specified resource block at a time, the next time the next selection may select different resource blocks to send data, thereby reducing the number of user terminals between the same unscheduled resources. Conflict probability, improve system transmission performance.

Step 406: When the base station detects the data carried by the specified resource block, the base station extracts an identity recognition sequence from the data.

When the user terminal sends data, the identity sequence is added to the specified location of the data. Correspondingly, when the base station detects the data carried by the unscheduled resource allocated to the user terminal, the sequence extracted by the specified location may be used as the identity. Identify the sequence.

Step 407: The base station calculates a matching value between the extracted identity sequence and the identity sequence, and detects whether the matching value is greater than a first threshold.

Step 408: If the detection result is that the matching value is greater than the first threshold, the base station determines the data as data sent by the user terminal.

Since the base station may simultaneously allocate the specified resource block to the plurality of user terminals as the unscheduled resource, when detecting the data carried by the specified resource block, the base station may use all the user terminals to which the specified resource block is allocated. The identity sequence is respectively calculated with the extracted identity sequence, and the user terminal whose matching value is greater than the first threshold confirms the data sending terminal.

When the base station detects that a plurality of user terminals transmit data through the specified resource block, the base station can receive multiple terminals through multiple antennas by using Multiple-Input Multiple-Output (MIMO) technology. The data sent by the specified resource block. When receiving data by using the MIMO technology, if the number of user terminals transmitting data through the specified resource block is less than or equal to the number of receiving antennas, in the case of full rank, the base station can demodulate data of all users, if simultaneously If the number of user terminals transmitting data in the specified resource block is greater than the number of receiving antennas, even if the full rank is not guaranteed, all data may be demodulated, which may cause data demodulation of some user terminals to fail. The data transmitted by the specified resource block conflicts, and the data sent by each user terminal fails to be demodulated once, which is recorded as a collision.

Step 409: The base station determines an unscheduled resource reconfiguration policy according to the usage information of the specified resource block.

The scheduling resource reconfiguration policy is used to increase or decrease resource blocks in the unscheduled resources allocated to the user terminal.

Please refer to FIG. 4B, which is a schematic diagram of the redistribution of the unscheduled resource according to the embodiment of the present invention, where the unscheduled resource originally allocated by the user terminal includes the resource blocks 1 to 4; when the base station adds the resource block to the user terminal, The resource block 5 and the resource block 6 may be added on the basis of the resource blocks 1 to 4, and the original resource blocks 1 to 4 are not changed; when the base station reduces the resource block for the user terminal, it may be in the resource blocks 1 to 4. Based on the reduction of

resource blocks

3 and 4, the original resource blocks 1 and 2 are not changed.

Adding resource blocks based on the original scheduling-free resources can effectively improve the robustness of the transmission. Specifically, when the resource block is added, if the base station sends a scheduling-free resource reconfiguration policy to the user terminal through control signaling, and the user terminal misses or misdetects the signaling, the base station and the user terminal understand the scheduling-free resource. There will be differences. At this time, the terminal still uses the resource block in the original unscheduled resource for transmission. If the unscheduled resource reconfiguration policy is to add a resource block based on the original unscheduled resource, the base station detects the original unscheduled resource. After the data is received, the identity sequence of the user terminal is still used for matching. At this time, the base station can detect the data sent by the user terminal. However, if the schedule-free resource reconfiguration policy does not add resource blocks on the basis of the original schedule-free resources, but redistributes other resource blocks, the base station will not use the data after detecting the data on the original schedule-free resources. User The identity sequence of the terminal is matched, so that the data sent by the user terminal on the original schedule-free resource is missed by the base station.

Similarly, reducing the resource block based on the original scheduling-free resources can also improve the robustness of the transmission to some extent. Specifically, when the resource block is reduced, if the base station sends a scheduling-free resource reconfiguration policy to the user terminal through control signaling, and the user terminal misses or misdetects the signaling, the base station and the user terminal understand the scheduling-free resource. There will be differences. At this time, the terminal still uses the resource block in the original unscheduled resource for transmission. If the unscheduled resource reconfiguration policy is to reduce the resource block on the basis of the original scheduling-free resource, the user terminal is in the original scheduling-free resource. When data is transmitted on a reserved portion of a resource block, the data can be identified by the base station. However, if the scheduling resource reconfiguration policy is not to reduce resource blocks on the basis of the original scheduling resources, but to reallocate other resource blocks, the user terminal transmits data on all resource blocks in the original scheduling resources. None of the data can be identified by the base station, so that the data sent by the user terminal on the original schedule-free resource is missed by the base station.

The specific methods for the base station to determine the rescheduling resource reconfiguration policy may be as follows:

1) When the usage information indicates that the number of user terminals to which the specified resource block is allocated is increased to be greater than a second threshold, determining that the unscheduled resource reconfiguration policy is to add m resource blocks based on the unscheduled resource, m ≥1.

2) when the usage information indicates that the number of user terminals to which the specified resource block is allocated is lowered below a third threshold, determining that the unscheduled resource reconfiguration policy is to reduce the inclusion of the specified resource block based on the unscheduled resource p resource blocks within, n>p≥1.

When the number of user terminals to which the same resource block is allocated as the unscheduled resource increases, the probability that the resource block is selected for data transmission also increases, and the probability that the data transmitted through the resource block collides also increases. Controlling, by the probability that the data transmitted by the resource block collides, when the number of user terminals to which the resource block is allocated as the unscheduled resource increases to a second threshold or more, the base station is based on the originally allocated unscheduled resource. Each user terminal to which the resource block is allocated adds at least one resource block.

Correspondingly, when the number of user terminals to which the resource block is allocated as the unscheduled resource is reduced below the third threshold, the probability that the resource block is selected for data transmission is relatively low. At this time, the base station may be originally allocated. On the basis of the unscheduled resource, at least one resource block including the resource block is reduced for each user terminal to which the resource block is allocated, thereby releasing the non-scheduled resource with low utilization rate and improving resource utilization. effectiveness. For example, when a base station increases or decreases a resource block that is a non-scheduled resource for a user terminal, the base station may increase or decrease the minimum granularity of the single resource block, or Increasing or decreasing with a resource block group containing multiple resource blocks as the lowest granularity; when increasing or decreasing with a single resource block as the lowest granularity, detecting the number of user terminals to which one resource block is allocated as an unscheduled resource After reducing to below the third threshold, the base station removes the resource block from all the unscheduled resources of the user terminal to which the resource block is allocated; when the resource block group containing multiple resource blocks is increased or decreased as the lowest granularity At the time of detecting that the number of user terminals to which one resource block is allocated as the unscheduled resource is reduced below the third threshold, the base station sets the resource block group in which the resource block is located from all the user terminals to which the resource block group is allocated. Remove from unscheduled resources.

3) When the usage information indicates that the total amount of data transmitted to the base station by the specified resource block in a unit time is greater than a fourth threshold, determining that the unscheduled resource reconfiguration policy is to add q on the basis of the unscheduled resource. Resource block, q≥1.

4) determining, when the usage information indicates that the total amount of data transmitted to the base station by the specified resource block in the unit time is less than a fifth threshold, determining that the unscheduled resource reconfiguration policy is to reduce the inclusion of the unscheduled resource i resource blocks including resource blocks, n>i≥1.

When the total amount of data transmitted to the base station through a certain resource block in a unit time is large, it indicates that the number of user terminals transmitting data through the resource block in the unit time is relatively large, and data transmitted through the resource block occurs. The probability of the collision also increases. At this time, the base station can add at least one resource block to each user terminal to which the resource block is allocated based on the originally allocated unscheduled resources.

Correspondingly, when the total amount of data transmitted to the base station through a certain resource block in a unit time is small, the number of user terminals transmitting data through the resource block in the unit time is small, and at this time, the base station can Based on the originally allocated scheduling-free resources, at least one resource block including the resource block is reduced for each user terminal to which the resource block is allocated.

5) determining, when the usage information indicates that the base station detects that the number of data collisions that are transmitted by using the specified resource block is greater than a sixth threshold, determining that the scheduling resource reconfiguration policy is On the basis of scheduling resources, j resource blocks are added, j≥1.

The number of collisions of data transmitted through a certain resource block in a unit time can most intuitively reflect the situation of data collision. Therefore, when the number of data transmitted through a certain resource block in a unit time conflicts frequently, the base station At least one resource block may be added to each user terminal to which the resource block is allocated, based on the originally allocated unscheduled resource.

Step 410: The base station sends a message including the unscheduled resource reconfiguration policy to the user terminal.

Step 411: The user equipment reconfigures the unscheduled resource according to the unscheduled resource reconfiguration policy.

The user terminal reconfigures the unscheduled resource according to the unscheduled resource reconfiguration policy sent by the base station. When the data is subsequently sent, one or more resource blocks are selected in the reconfigured non-scheduled resource for data transmission until the next time the non-scheduled resource is received. Reconfigure the policy.

The data transmission method provided by the embodiment of the present invention, when the base station reconfigures the scheduling resource of the user terminal, the unscheduled resource reconfiguration policy determined by the base station is used to increase the unscheduled resource allocated to the user terminal or The resource block is reduced, so that when the unscheduled resource reconfiguration policy is missed or misdetected by the user terminal, the data sent by the user terminal through the original unscheduled resource still has a certain probability to be recognized by the base station, thereby improving the data transmission. Great.
