Service scheduling method, device and system

technical field

The present invention relates to the technical field of mobile communication, in particular to a service scheduling method, device and system.

Background technique

Long Term Evolution (LTE) technology is the evolution of 3G technology. LTE improves and enhances the 3G air access technology. Under the 20MHz spectrum bandwidth, it can provide a peak rate of downlink 100Mbit/s and uplink 50Mbit/s, which improves the performance of cell edge users, increases cell capacity and reduces system delay. Therefore, LTE technology has been widely recognized by the industry, and operators have begun to vigorously deploy LTE networks.

MediaFLO (MediaFLO) technology is the broadcast data transmission technology of Qualcomm for mobile phones, personal digital assistants and other portable equipment. The broadcast data includes a variety of real-time video streams, independent or non-real-time video "short films", such as stock market trends, sports scores, and IP data broadcasting applications such as weather reports. The MediaFLO system is a piece of transmission data divided from the spectrum usage of the existing mobile network. For example, the spectrum of MediaFLO used in the United States is 716-722MHz.

When operators build LTE networks using frequency bands where MediaFLO broadcasts exist, for example, US operators AT&T and Verizon use 700MHz frequency bands where MediaFLO broadcasts exist to build LTE networks, and a dual-mode terminal emerges as the times require. As shown in Figure 1, a typical dual-mode terminal is shown. An LTE duplexer and a MediaFLO receiver are integrated in this dual-mode terminal. The LTE duplexer is used for transmitting/receiving LTE data (TX/RX ), the MediaFLO receiver is used to receive MediaFLO broadcasts, and the LTE duplexer and the MediaFLO receiver share the same antenna.

In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art:

The aforementioned dual-mode terminal including an LTE duplexer and a MediaFLO receiver will generate self-interference to the reception of MediaFLO broadcasts when transmitting LTE data in the uplink direction. For example, if the MediaFLO broadcast bandwidth is 6MHz, the effective bandwidth is 5.6MHz, and the noise figure of the MediaFLO receiver is 8dB, in this scenario, the isolation required between the LTE duplexer and the MediaFLO receiver sharing the antenna can be calculated The degree is 80dB, otherwise, it will affect the normal operation of the dual-mode terminal. If the above-mentioned isolation is achieved by inserting additional devices into the terminal, this kind of insertion process will cause a lot of loss to the existing terminal, and it is necessary to increase the size and function of the processing chip in the terminal. The requirements for the terminal are too high and the cost is very high. Not feasible in application. There is an urgent need for a method for solving the self-interference problem in the above-mentioned dual-mode terminal.

Moreover, the technical solution of the embodiment of the present invention does not need to add additional equipment to the terminal, fully utilizes existing resources, consumes little cost, and has great feasibility in practical applications.

The technical solution provided by Embodiment 4 of the present invention will be described in detail below.

According to the technical solution provided by Embodiment 4 of the present invention, relevant network elements on the network side can obtain service scheduling information. According to the service scheduling information, the scheduling terminal does not perform the second service when executing the first service, so as to avoid the first service and the second service. Problems caused by conflicts when services exist at the same time, such as self-interference phenomenon, or problems caused by conflicts caused by the simultaneous existence of the first service and the second service by controlling on the terminal side, such as self-interference phenomenon. Wherein, the above-mentioned first service is uplink transmission of wireless communication data, and the above-mentioned second service is reception of broadcast data; or, the above-mentioned first service is reception of broadcast data, and the above-mentioned second service is uplink transmission of wireless communication data.

Case 1: Controlled by the network side to avoid self-interference

First, relevant network elements on the network side, such as evolved base stations (eNBs), need to obtain service scheduling information. The foregoing service scheduling information may be scheduling information related to the first service, or include scheduling information related to the second service, or be scheduling information related to the first service and the second service. The first service and the second service are any two possible services that may conflict when they exist at the same time and cause impact on the terminal, such as self-interference, and need to be scheduled.

In the embodiment of the present invention, the scenario of scheduling the uplink transmission service of data in LTE and the reception service of MediaFLO data is mainly used as an example for description. Further, in the embodiment of the present invention, the above service scheduling information selects the service scheduling information related to MediaFLO. But not limited thereto, for example, this technical solution can be applied to other scenarios where the transmission of uplink data interferes with the reception of downlink data, such as the above-mentioned broadcast data can also be multimedia broadcast multicast service (MBMS) data, handheld digital video broadcasting (DVB-H) data, terrestrial digital multimedia broadcasting (DMB) or integrated services digital broadcasting-terrestrial transmission (ISDB-T) data and other broadcast data.

Exemplarily, the above service scheduling information may include the start time (Start) and duration (Duration) of the terminal receiving the MediaFLO data, or the above service scheduling information may include the start time and end time of the terminal receiving the MediaFLO data. Before the terminal receives the MediaFLO service each time, the base station acquires the service scheduling information.

Further, when the MediaFLO data is sent periodically, and the time information of the MediaFLO data in each period is the same, the above service scheduling information may include the start time (Start), duration (Duration) and period of the terminal receiving the MediaFLO data (Period), or, the above-mentioned service scheduling information may include the start time, end time and period of the terminal receiving the MediaFLO data, and the base station only needs to obtain the service scheduling information once to know the time information of the terminal receiving the MediaFLO data.

But not limited thereto, the scheduling information may include any time information required by the eNB to instruct the terminal to receive the MediaFLO data when the eNB performs service scheduling.

The eNB can obtain the above-mentioned MediaFLO service scheduling information in a variety of ways, for example, at least including the following two ways:

Method 1: Receive the service scheduling information of MediaFLO sent by the terminal

The eNB receives the above-mentioned MediaFLO service scheduling information sent by the terminal.

A dedicated signaling can be added, and the terminal sends the service scheduling information of MediaFLO to the eNB through the newly added dedicated signaling. The operating mechanism of the terminal ensures that the terminal can obtain the service scheduling information of the MediaFLO. For example, when the terminal receives a system message or broadcast signaling in the system, it parses the system message or broadcast signaling to obtain the corresponding MediaFLO service scheduling information, or the terminal obtains the corresponding MediaFLO from the received MediaFLO packet. At this time, the MediaFLO data packet carries a control information packet, and the control information packet includes the above-mentioned MediaFLO service scheduling information.

Mode 2: Receive service indication information sent by the terminal, and acquire the stored service scheduling information according to the service indication information.

In this manner, the eNB stores the service scheduling information of the MediaFLO that needs to be scheduled in advance. The terminal only needs to report the service indication information of MediaFLO, and the eNB queries all the stored service scheduling information according to the service indication information, and reads the matching service scheduling information.

Taking the 6MHz bandwidth as an example, MediaFLO can provide 20 300kbps Mobile TV services, and set an identifier for each Mobile TV service. The eNB obtains and saves the service scheduling information of the 20 Mobile TV services, and saves the correspondence between the Mobile TV service and the identifier. relationship, the identification is used as service indication information, the terminal only needs to report the identification, and the eNB queries the corresponding relationship according to the received identification, and can obtain the corresponding service scheduling information of MediaFLO.

The following describes the situation where the eNB uses the above service scheduling information to perform control processing to avoid sending uplink data in the LTE system when the terminal receives MediaFLO data. Here, the uplink data in the LTE system that needs to be sent includes any uplink data information sent by the terminal to the eNB in the LTE system. Through the description of the following exemplary uplink data transmission in the LTE system, those skilled in the art can clearly understand A control method for uplink transmission scenarios of all LTE data. The following processes are performed respectively for the terminal to send data and signals in different uplink channels:

(1) Physical Uplink Shared Channel (PUSCH):

Data sent on the PUSCH includes dynamic scheduling data and semi-persistent scheduling data.

For dynamic scheduling data, each time the dynamic scheduling data is sent, the terminal first sends a Resource Request Indicator (Source Request Indicator, SRI) message to the eNB, and the eNB sends Physical Downlink Control Channel (PDCCH) signaling according to the SRI message, The control terminal PUSCH dynamically schedules the sending of data.

In the embodiment of the present invention, the eNB controls the reception of MediaFLO data and the uplink transmission of PUSCH dynamic scheduling data according to the service scheduling information, as shown in Figure 4, specifically including the following steps:

Step T1: The eNB receives the service scheduling information of MediaFLO sent by the terminal.

The service scheduling information indicates the time information for the terminal to receive MediaFLO data, for example, the service scheduling information is the start time and duration of the terminal receiving MediaFLO data, or the service scheduling information is the start time and end time of the terminal receiving MediaFLO data .

Step T2: When the terminal needs to perform uplink transmission of PUSCH dynamic scheduling data, the terminal sends an SRI message to the eNB, requesting the eNB to allow the transmission of the dynamic scheduling data.

Step T3: After receiving the above SRI message, the eNB performs scheduling according to the service scheduling information.

If the eNB judges according to the service scheduling information that when sending the dynamic scheduling data, the terminal is receiving the MediaFLO service, that is, when the uplink sending of the dynamic scheduling data conflicts with the receiving of the MediaFLO data, the scheduling result can be that the terminal is rejected. The sending of the above-mentioned dynamic scheduling data. If the uplink sending of the dynamic data does not conflict with the receiving of the MediaFLO data, the scheduling result may be to allow the sending of the dynamic data.

Further, if the dynamic scheduling data is of high importance, the uplink transmission of the dynamic data is prioritized. At this time, the scheduling result is that the terminal stops receiving MediaFLO data and performs uplink transmission of the dynamic scheduling data.

Step T4: The eNB sends PDCCH signaling to the terminal, and the PDCCH signaling carries the above scheduling result.

Step T5: The terminal obtains the scheduling result by analyzing the received PDCCH signaling.

When the scheduling result is that the uplink transmission of the dynamic scheduling data is allowed, the PUSCH data is sent to the eNB. Or, when the scheduling result is to reject the uplink transmission of the dynamic scheduling data, do not send the PUSCH data; or, when the scheduling result is to stop receiving MediaFLO data and send the dynamic scheduling data, the terminal stops receiving MediaFLO data to send the dynamic Scheduling data.

For semi-persistent scheduling data, when the data is sent for the first time, the terminal sends an SRI message to the eNB, and the eNB sends PDCCH signaling to the terminal according to the SRI message, and the sending period of the semi-persistent scheduling data in the PDCCH signaling and time are configured, and the terminal sends the semi-persistent scheduling data according to the configuration in the PDCCH signaling. During subsequent processing, the terminal directly executes the sending of the semi-persistently scheduled data according to the configured sending period and time, without using the SRI message to request the eNB.

In the embodiment of the present invention, the eNB learns from the service scheduling information that when the terminal performs the uplink transmission of the semi-persistently scheduled data, there is a service for receiving MediaFLO data, and the eNB retransmits the PDCCH signaling to the terminal for semi-persistently scheduled data. Re-set the sending cycle and time, adjust the sending cycle and time of semi-statically scheduled data, etc., to avoid the reception of MediaFLO data, so that the uplink sending of semi-statically scheduled data does not conflict with the reception of MediaFLO data, thereby avoiding self-interference happened.

The above-mentioned uplink transmission of the PUSCH data may also be followed by uplink transmission of a reference signal (RS), at this time, the processing method for the RS may refer to the above-mentioned processing method for the PUSCH data.

(2) Physical Uplink Control Channel (PUCCH)

The PUCCH signaling may be sent along with the PUSCH signaling. In this case, for the scheduling method, refer to the scheduling method for the PUSCH data sent uplink.

Further, the PUCCH signaling can also be used for uplink transmission of acknowledgment/non-acknowledgement (ACK/NACK) messages, channel quality indication (CQI) messages, SRI messages or RSs.

For the ACK/NACK message, these two messages are feedback messages sent by the terminal to the physical downlink shared channel (PDSCH) data sent by the eNB. The ACK message indicates that the PDSCH data is successfully received, and the NACK message indicates that the PDSCH data is failed to be received. The eNB can obtain the timing relationship between the PDSCH data it sends and the ACK/NACK message fed back by the terminal according to the settings, and judge whether the terminal needs to send an ACK/NACK message while receiving MediaFLO data according to this timing relationship , if this situation exists, the eNB will no longer send the corresponding PDSCH data.

In the frequency division duplex (FDD) system of LTE, the ACK/NACK message fed back by the terminal at time n through PUCCH signaling corresponds to the PDSCH data sent by the eNB at time (n-4). Therefore, when the eNB wants to send PDSCH data to the terminal, and judges according to the service scheduling information of MediaFLO that the terminal needs to receive MediaFLO data after 4 moments, the eNB will no longer send the corresponding PDSCH data.

In LTE Time Division Duplex (TDD), the ACK/NACK fed back by the terminal at time n through PUCCH signaling corresponds to the PDSCH data sent by the base station to the terminal at (n-k) time. For the value of k, refer to the following table:

Table 1

Table 1 illustrates the value of k in 9 sub-frames in different modes (mode 0 to mode 6). The leftmost column in Table 1 is the mode configured by the PDSCH, and "-" indicates that the corresponding subframe is an uplink subframe. It can be known from Table 1 that in mode 0, the value of k for subframe 2 is 6. In this case, when the eNB wants to send PDSCH data to the terminal, it is judged according to the service scheduling information of MediaFLO that the terminal needs to receive MediaFLO data after 6 moments, then the eNB will no longer send the corresponding PDSCH data.

Further, when the above-mentioned PDSCH data is of high importance, the terminal can be scheduled to stop receiving MediaFLO data at the corresponding time, and send PDSCH data to the terminal at the corresponding time. For example, taking the above-mentioned LTE FDD system as an example, the eNB sends the terminal at the current time Send PDSCH data, and schedule the terminal to stop receiving MediaFLO data after 4 moments, so that the terminal sends corresponding PUCCH signaling messages, such as ACK/NACK messages, after 4 moments.

For CQI and SRI, both the sending period and time offset (offset) can be configured by the eNB, for example, the period of CQI can be configured within a range from 2 subframes to 160 subframes.

When the terminal receives the MediaFLO service, the uplink transmission of CQI and SRI is required according to the configuration, and the eNB reconfigures the sending cycle and offset of the CQI and SRI to avoid the uplink data transmission while receiving the MediaFLO service. send.

(3) Sounding Reference Signal (SRS)

The SRS is set in the last block of a subframe, and the frequency domain interval of the SRS is two equivalent subcarriers. The period and offset of the SRS are configured by the eNB, and the period can be configured from 2 subframes to 160 subframes. Therefore, the SRS can also be controlled by the eNB on the network side.

When the terminal receives MediaFLO data, the terminal needs to perform SRS uplink transmission according to the eNB configuration, the eNB reconfigures the SRS transmission cycle and offset, and the scheduling terminal does not perform SRS transmission when receiving MediaFLO data. Or, the terminal stops receiving the MediaFLO data, and sends the SRS according to the configuration of the eNB, so as to avoid sending the uplink data while the terminal is receiving the MediaFLO data.

In the above processing, signaling, data or messages that cannot be sent normally due to the scheduling processing can be resent at a subsequent allowed time.

Case 2: Control by the terminal side to avoid self-interference

The terminal can directly schedule the reception of MediaFLO data and the transmission of LTE uplink data on the terminal according to the acquired service scheduling information.

The terminal side performs the following processing for different uplink channels and signal transmissions:

(1)PUSCH

When receiving MediaFLO data, the terminal does not send PUSCH data. During the period of receiving MediaFLO data, the terminal may not send semi-static PUSCH data, or, when the terminal receives PDCCH signaling from the eNB indicating to send PUSCH data, and is receiving MediaFLO data at this time, the terminal may refuse to send the PUSCH data, or when the PDCCH signaling indicates that the PUSCH data is of high importance, the terminal stops receiving MediaFLO data and performs uplink transmission of PUSCH data.

When sending the above PUSCH data, the RS may also be sent at the same time, for the processing method of the RS, please refer to the processing method of the above PUSCH data.

(2)PUCCH

During receiving MediaFLO data, the terminal does not feed back ACK/NACK messages to the eNB (the eNB may retransmit the corresponding PDSCH).

During the period of receiving MediaFLO data, the terminal may not send an SRI message to the eNB to request sending of PUSCH data, or may not send a CQI.

(3) SRS

During receiving the MediaFLO service, the terminal does not transmit SRS.

(4) Physical Random Access Channel (PRACH)

The PRACH is used to send signaling to the network when the terminal establishes an initial connection with the network, or to respond to a paging message from the network, and can also be used to send discontinuous data. The eNB configures the subframe of the PRACH, as shown in Table 2, which provides the specific information of the configurable subframe of the PRACH.

Table 2

The timing of sending PRACH data is controlled by the terminal. According to the service scheduling information, when the terminal is not receiving MediaFLO data, the terminal sends physical random access channel PRACH data, or stops receiving MediaFLO data and sends PRACH data .

In the above processing, signaling, data or messages that cannot be sent normally due to the scheduling processing can be resent at a subsequent allowed time.

In the technical solution provided by the embodiments of the present invention, through scheduling processing, when the scheduling terminal receives MediaFLO data, it stops uplink transmission of data in LTE, or the scheduling terminal stops receiving MediaFLO data, and performs uplink transmission of data in LTE. Therefore, it is avoided that the data in the LTE transmitted in the uplink direction causes self-interference to the reception of the MediaFLO broadcast, which affects the operation of the terminal. Moreover, the technical solution of the embodiment of the present invention does not need to add additional equipment to the terminal, fully utilizes existing resources, consumes little cost, and has great feasibility in practical applications.
