Description

Base station and its resource allocation method based on semi-permanent scheduling

The present invention relates to a base station and its resource allocation method, and more particularly to a base station and its resource allocation method based on Semi-Persistent Scheduling (SPS).

When packet transmission is carried out in the mobile network, dynamic scheduling (Dynamic Scheduling) is usually used. Dynamic scheduling can be understood as a request for wireless resources that can be used to transmit data when the transmission is about to begin. Generally speaking, the uplink data transmitted by user equipment (UE) requests radio resources based on a scheduling request (Scheduling Request).

Different from the above-mentioned dynamic scheduling mechanism, SPS allows an enhanced node B (enhanced node B, eNB) to semi-statically configure radio resources to periodically allocate radio resources to a specific UE. Due to the characteristics of SPS, such as sustainable and stable scheduling and saving control packets (such as downlink control information (DCI) packets), in a cellular system, SPS can be used for voice calls on LTE networks Service (Voice over LTE, VoLTE) transmission or other future communication systems, such as 5G systems. Since SPS only needs one scheduling to achieve the effect of multiple transmissions, the SPS mechanism is very important for a cellular system to implement VoLTE.

According to the 3GPP TS 36.321 specification, when the SPS mechanism is adopted between the UE and the eNB, the eNB will periodically allocate resources to the UE. Correspondingly, the UE will also periodically transmit data to the eNB through an uplink. If the UE wants to end the call and no longer needs to use the aforementioned allocated resources, the UE will send a preset amount of pending data (pending data).

However, in some cases, if the eNB cannot successfully receive the above-mentioned undecided data, wireless resources may be wasted.

The present invention provides an SPS-based resource allocation method suitable for a base station, including: periodically receiving multiple uplinks (UL) corresponding to the user equipment on a radio resource assigned to a user equipment Data; in response to the continuous reception of a preset number of specific uplink data from the user equipment, perform a release SPS operation to stop receiving other uplink data corresponding to the user equipment on the radio resource, wherein the aforementioned specific uplink data is determined by at least one Data and at least one error data, or only at least one error data.

The present invention provides a base station, which includes a storage circuit, a transceiver and a processor. The storage circuit stores multiple modules. The processor is coupled to the receiver transmitter and the storage circuit, and accesses the aforementioned modules to perform the following steps: controlling the transceiver to periodically receive a plurality of uplinks corresponding to the user equipment on a wireless resource assigned to a user equipment ( uplink, UL) data; in response to the continuous reception of a preset number of specific uplink data from the user equipment, a semi-persistent scheduling (SPS) operation is performed to stop receiving the corresponding use on the wireless resource Other uplink data of the device, wherein the aforementioned specific uplink data consists of at least one undecided data and at least one error data, or only consists of at least one error data.

Based on the above, the base station and its SPS-based resource allocation method proposed by the present invention allow the base station to continuously receive a preset number of specific uplink data (which consists of undecided data and at least one error data), and release the allocation accordingly. The radio resources of the UE. In this way, unnecessary waste of wireless resources due to CRC errors can be avoided, and communication efficiency can be improved.

In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail in conjunction with the accompanying drawings.

Please refer to FIG. 1, which is a schematic diagram of an SPS mechanism according to an embodiment of the present invention, and the horizontal axis in the figure represents time. In this embodiment, the eNB may have a physical layer (physical layer, L1 for short), a medium access control layer (L2 for short), and a radio link control layer (L3 for short) .

As shown in Figure 1, when the eNB wants to use SPS to communicate with the UE, the eNB L3 can send a UE re-configuration (UE re-configuration) signal to the UE to enable SPS UL. After the UE receives the UE reconfiguration signal, the UE can know that it will send UL data to the eNB based on the SPS mechanism.

Then, the eNB L2 can send an SPS UL activation (activation) signal to the UE to formally activate the SPS mechanism. After that, the UE can periodically use the radio resources allocated by the eNB L2 to transmit UL data. Correspondingly, the eNB L2 can control the eNB L1 to periodically listen to the UL data sent by the UE on the radio resources allocated to the UE based on the UL configuration signal. In this embodiment, the SPS period for the UE to transmit UL data is, for example, 20 ms, but the invention is not limited to this. In other embodiments, the SPS period can also be adjusted to other values specified in the specification, such as 160 ms. In this embodiment, taking the LTE system as an example, the SPS UL activation signal is a DCI (downlink control information, DCI) packet, but it is not limited to this. The SPS UL activation signal is used to control SPS in different communication systems. Command or packet to decide.

In different embodiments, the SPS mechanism can be terminated by the methods described in FIG. 2 and FIG. 3.

Please refer to FIG. 2, which is a schematic diagram of ending the SPS mechanism according to an embodiment of the present invention. The horizontal axis in the figure represents time. In this embodiment, when the eNB wants to terminate the SPS mechanism, the eNB L2 may send an SPS UL release (release) signal to the UE. Correspondingly, the UE will not continue to transmit UL data periodically, and the eNB L2 will no longer control the eNB L1 to periodically listen to the UL data sent by the UE on the radio resources allocated to the UE based on the UL configuration signal. In this embodiment, taking the LTE system as an example, the SPS UL release signal is a DCI (downlink control information, DCI) packet, but it is not limited to this. The SPS UL release signal is used to control SPS in different communication systems. Command or packet to decide.

Please refer to FIG. 3, which is a schematic diagram of ending the SPS mechanism according to another embodiment of the present invention. The horizontal axis in the figure represents time. In this embodiment, if the UE wants to end the SPS mechanism, the UE can continuously send a preset number (hereinafter referred to as N) undecided data to the eNB L2, where the undecided data includes, for example, only headers but not Payload (payload) data, but not limited to this. After that, the UE can release the SPS. That is, the UE no longer (periodically) transmits UL data to the eNB. Correspondingly, after the eNB L2 continuously receives the preset number of undecided data, the eNB L2 can also release the SPS. In other words, the eNB L2 can no longer control the eNB L1 to periodically listen to the UL data sent by the UE on the radio resources allocated to the UE based on the UL configuration signal, that is, no longer allocate radio resources to the UE. In this embodiment, the above-mentioned preset number is, for example, 8, which can be designated by the eNB L3 in the enabling SPS UL signal, but the invention is not limited to this.

In the present invention, the mechanism shown in FIG. 3 may also be referred to as an implicit release (implicit release). However, in the implicit release mechanism, if some undetermined data is not successfully received by the eNB, the UE and the eNB may not be able to release the SPS smoothly, which may cause a waste of resources.

Please refer to FIG. 4, which is a schematic diagram of resource waste according to an embodiment of the present invention, and the horizontal axis in the figure represents time. In this embodiment, it is assumed that the UE has continuously sent a preset number (ie, 8) of undetermined data, but the undetermined data 410 (ie, the eighth undetermined data) may be due to poor channel conditions or other similar reasons It is not received correctly by the eNB. Specifically, after the eNB receives the undetermined data 410, the eNB may first perform operations such as cyclic redundancy check (CRC) on the undetermined data 410 to confirm the checksum calculated based on the undetermined data 410 is it right or not. However, in a scenario where the channel condition is poor, the eNB may determine that a CRC error has occurred due to the failure to successfully complete the CRC operation on the undecided data 410. In this case, the eNB may request the UE to transmit the pending data 410 again based on a hybrid automatic repeat request (HARQ) mechanism.

However, before the eNB successfully receives the undetermined data 410 (for example, completes the CRC operation on the undetermined data 410 and successfully parses the content of the undetermined data 410), the eNB cannot determine whether the undetermined data 410 is really a piece of undetermined data. At this time, if the undecided data 410 cannot be successfully received for a long time due to poor channel conditions, the eNB may need to repeatedly request the UE to retransmit the undecided data based on HARQ. In this case, the wireless resources will be occupied unnecessarily, which will cause waste.

In addition, after the UE continuously transmits a preset number of undecided data, it may also directly perform the operation of releasing the SPS and no other data is transmitted. However, if the eNB misjudges the unsuccessfully received undecided data 410 as UL data, the eNB L2 will still control the eNB L1 to listen to the UL data sent by the UE on the radio resources allocated to the UE based on the UL configuration signal. Since the UE has released the SPS, the eNB L1 will not receive the UL data transmitted by the UE, which is a waste of radio resources.

In addition, suppose that the UE sends a piece of UL data after continuously transmitting (N-1) undecided data, but the UL data is not successfully parsed by the eNB for some reason. In this case, if the eNB misjudges the unsuccessfully received UL data as undetermined data, the eNB will perform the SPS release operation due to the determination that it has continuously received N undetermined data. That is, the eNB L1 will no longer listen to the transmitted UL data on the radio resources allocated to the UE. As a result, the data subsequently sent by the UE cannot be successfully transmitted to the eNB.

Furthermore, after the eNB releases the SPS, the eNB may also allocate the radio resources originally allocated to the UE to other UEs. In this case, two UEs may collide because they use the same radio resources for transmission.

In an embodiment, when a radio link failure (Radio Link Failure) occurs between the UE and the eNB, the eNB may also need to activate a corresponding connection recovery mechanism. However, this recovery mechanism may take up to 10,000 ms at most, thus reducing the overall system performance.

In addition, in a centralized radio access network (C-RAN) architecture, problems similar to the above-mentioned situation may also occur. Specifically, in the C-RAN, the eNB L1 and the eNB L2 may be respectively set in different machines, so that there may be a certain degree of latency in the transmission between the eNB L1 and the eNB L2. In this case, when the eNB L2 receives the data retransmitted by the UE in response to the HARQ mechanism, regardless of whether the eNB L1 has correctly received the data, the eNB L2 will first send a HARQ acknowledgement (ACK) signal. However, in the context of implicit release, the above mechanism may cause a waste of wireless resources.

Please refer to FIG. 5, which is a schematic diagram of the implicit release in the C-RAN architecture according to an embodiment of the present invention. The horizontal axis in the figure represents time. In this embodiment, it is assumed that the UE has continuously transmitted N undetermined data and released the SPS, but the eNB encountered a CRC error when parsing the undetermined data 510 (ie, the Nth undetermined data). As described in the previous embodiment, the eNB L2 may first return HARQ ACK at this time. However, since the eNB has not correctly parsed the undetermined data 510, it may still try to listen to the data from the UE again after the SPS period, which is a waste of radio resources. At the same time, since the UE does not send any data after the SPS period, the eNB may again determine that a CRC error has occurred. In addition, when the eNB L2 finds that the undetermined data 510 is not correctly parsed, the eNB L2 can also request the UE to retransmit the undetermined data 510 through a DCI request.

In view of this, the present invention provides a base station and a scheduling method thereof, which can be used to solve the above technical problems.

Please refer to FIG. 6, which is a functional block diagram of an eNB according to an embodiment of the present invention. In this embodiment, the eNB 600 can be broadly understood as a general base station, a macro-cell base station, a pico-cell base station, or a remote radio head (remote radio). radio head, RRH), but not limited to this.

The A/D converter or D/A converter is configured to convert the analog signal format to a digital signal format during the upstream signal processing, and to convert the digital signal format to the analog signal format during the downstream signal processing.

The processor 606 is coupled to the storage circuit 602 and the transceiver 604, and can be a general purpose processor, a special purpose processor, a traditional processor, a digital signal processor, multiple microprocessors, one or more Microprocessors, controllers, microcontrollers, Application Specific Integrated Circuits (ASICs), Field Programmable Gate Arrays (Field Programmable Gate Arrays, FPGAs), and any other types that combine the core of the digital signal processor Integrated circuit, state machine, processor based on Advanced RISC Machine (ARM) and similar products.

In the embodiment of the present invention, the processor 606 can load the program codes or modules recorded in the storage circuit 602 to execute the SPS-based resource allocation method proposed by the present invention, which will be further described below.

Please refer to FIG. 7, which is a flowchart of a method for resource allocation based on SPS according to an embodiment of the present invention. The method in this embodiment can be executed by the eNB 600 in FIG. 6. The details of each step in FIG. 7 are described below with the elements shown in FIG. 6.

First, in an embodiment, the processor 606 may arrange radio resources for the UE based on the SPS mechanism. In an embodiment, the processor 606 may send the SPS UL start signal shown in FIG. 1 to FIG. 3 to the UE to inform the UE of its allocated radio resources. Accordingly, the UE can periodically use the allocated radio resources to transmit uplink data to the eNB 600. In this embodiment, taking the LTE system as an example, the SPS UL activation signal is a DCI (downlink control information, DCI) packet, but it is not limited to this. The SPS UL activation signal is used to control SPS in different communication systems. Command or packet to decide.

In step S710, the processor 606 may control the transceiver 604 to periodically receive multiple UL data corresponding to the UE on the radio resources assigned to the UE. In an embodiment, the processor 606 may control the transceiver 604 to periodically receive the uplink data transmitted by the UE in the above-mentioned radio resources according to the UL configuration signal shown in FIGS. 1 to 3. For the details of arranging radio resources for the UE based on the SPS mechanism and the details of step S710, please refer to the description in the previous embodiment, which will not be repeated here.

Afterwards, in step S720, in response to the continuous reception of a predetermined number of specific uplink data from the UE, the processor 606 may perform an SPS release operation to stop receiving other uplink data corresponding to the UE on the radio resource. In the embodiment of the present invention, the predetermined number of specific uplink data may be composed of at least one undecided data and at least one error data, or only composed of error data. The aforementioned error data is, for example, CRC error data. However, the present invention It is not limited to this.

In an embodiment, the processor 606 may initialize a count value to 0, where the count value may be characterized as the number of specific uplink data that has been continuously received. Thereafter, whenever the processor 606 receives an uplink data from the UE, the processor 606 can determine whether the uplink data is undecided data or erroneous data. If so, the processor 606 can accumulate the above-mentioned count value. On the other hand, if the upstream data is not undetermined or erroneous data, it means that the upstream data is normal upstream data with payload. In this case, the processor 606 may reset the aforementioned count value to zero. When the aforementioned count value is accumulated to the preset number, it means that the processor 606 has continuously received the preset number of specific uplink data from the UE. Therefore, the processor 606 may correspondingly perform the release SPS operation to release the wireless resources, but the present invention may not be limited thereto.

In order to make the concept of step S720 clearer, the following is supplemented with FIG. 8 for further description. Please refer to FIG. 8, which is a schematic diagram illustrating a mechanism for releasing SPS according to an embodiment of the present invention. The horizontal axis in the figure represents time. In this embodiment, it is assumed that the preset number is 8 (ie, N is 8), and the UE 810 continuously sends 8 undecided data 811, 812, ..., 818. However, eNB 600 encountered a CRC error when parsing undecided data 818. That is, after the eNB 600 successfully parsed 7 undecided data 811 to 817, it is determined that one wrong data 818a has occurred.

At this time, the eNB 600 can determine that it has continuously received a predetermined number of specific uplink data (ie, 7 undecided data 811~817 and 1 error data, of which the undecided data 813~817 are not shown in the figure), and can execute the release of SPS Operate to stop receiving other uplink data corresponding to the UE 810 on the radio resources allocated to the UE 810. In addition, the eNB 600 can also control the UE 810 to also perform the SPS release operation through the SPS UL release signal. In this embodiment, taking the LTE system as an example, the SPS UL release signal is a DCI (downlink control information, DCI) packet, but it is not limited to this. The SPS UL release signal is used to control SPS in different communication systems. Command or packet to decide.

That is, in response to the eNB 600 determining that the predetermined number of specific uplink data has been continuously received, both the eNB 600 and the UE 810 will perform the SPS release operation. In this way, the various waste of wireless resources mentioned in the previous embodiments can be avoided, thereby improving the performance of the overall system.

It should be understood that the aspect of the specific uplink data shown in FIG. 8 is only for example, and is not intended to limit the possible implementation of the present invention. In other embodiments, the data in which the CRC error occurs may also be one or more of the undecided data 811 to 817, and is not limited to the undecided data 818. In short, as long as the eNB 600 determines that it has received N consecutive specific uplink data consisting of undecided data and erroneous data, both the eNB 600 and the UE 810 can perform the SPS release operation to achieve the effect of saving uplink resources.

Furthermore, compared to the method in FIG. 4 that will take up to 10,000 ms, the method proposed by the present invention hardly consumes extra time, and therefore can improve the efficiency of the overall system.

In addition, in an embodiment, after both the eNB 600 and the UE 810 perform the SPS release operation, the eNB 600 may send the SPS UL start signal to the UE 810 again to restart the SPS mechanism between the eNB 600 and the UE 810. After that, the eNB 600 and the UE 810 can communicate again based on the method shown in FIG. 1, and the details are not repeated here. In this embodiment, taking the LTE system as an example, the SPS UL activation signal is a DCI (downlink control information, DCI) packet, but it is not limited to this. The SPS UL activation signal is used to control SPS in different communication systems. Command or packet to decide.

In addition, in an embodiment, the method proposed by the present invention is also applicable to the eNB 600 belonging to the C-RAN.

Please refer to FIG. 9, which is a schematic diagram of a mechanism for releasing SPS according to another embodiment of the present invention. The horizontal axis in the figure represents time. In this embodiment, it is assumed that the preset number is 8 (ie, N is 8), and the undetermined data 918 is, for example, the eighth undetermined data sent by the UE 910 after 7 undetermined data (not shown) continuously. However, as shown in FIG. 9, the eNB 600 encountered a CRC error when parsing the undecided data 918. That is, after the eNB 600 successfully parsed 7 pieces of undecided data, it is determined that 1 piece of error data 918a has occurred.

As described in the previous embodiment, before specifically recognizing that a CRC error has occurred, the L2 of the eNB 600 will first transmit a HARQ ACK to the UE. However, since the eNB 600 determines that it has continuously received a preset number of specific uplink data (ie, 7 undecided data and 1 error data) at this time, the SPS release operation can be performed to stop the radio resources allocated to the UE 910 Other uplink data corresponding to the UE 910 is received on the uplink. In addition, the eNB 600 can also control the UE 910 to also perform the SPS release operation through the SPS UL release signal. In this embodiment, taking the LTE system as an example, the SPS UL release signal is a DCI (downlink control information, DCI) packet, but it is not limited to this. The SPS UL release signal is used to control SPS in different communication systems. Command or packet to decide.

That is, in response to the eNB 600 determining that the predetermined number of specific uplink data has been continuously received, both the eNB 600 and the UE 910 will perform the SPS release operation. In this way, the various waste of wireless resources mentioned in the previous embodiments can be avoided, thereby improving the performance of the overall system.

Then, after the L2 of the eNB 600 finds that a CRC error has occurred, the eNB 600 can request the UE 910 to retransmit the pending data 918 through a DCI request to complete the transmission with the UE 910.

In summary, the base station and its SPS-based resource allocation method proposed by the present invention enable the base station to continuously receive a predetermined number of specific uplink data (which consists of undecided data and at least one error data) and release accordingly The radio resources allocated to the UE. In this way, unnecessary waste of wireless resources due to CRC errors can be avoided, and communication efficiency can be improved. In addition, for base stations belonging to the C-RAN, the method of the present invention can also be used to avoid unnecessary waste of wireless resources due to CRC errors and improve communication efficiency.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Anyone with ordinary knowledge in the technical field can make some changes and modifications without departing from the spirit and scope of the present invention.
