Detailed ways

In order to make the purpose, technical solutions, and advantages of the present application clearer, the implementation manners of the present application will be described in further detail below in conjunction with the accompanying drawings.

Before detailed introduction to the data receiving method provided by the embodiment of the present application, a brief introduction to the technical terminology, application scenarios, and implementation environment involved in the present application will be given.

First, a brief introduction to the professional terms involved in this application.

BWP: It can support network equipment to configure bandwidth according to the actual throughput of the UE. For example, if the rate of the UE is very low, a smaller bandwidth can be configured for the UE, and if the rate of the UE is very high, a larger bandwidth can be configured for the UE. In addition, if the UE supports a high rate, or the UE works in a CA (Carrier Aggregation, carrier aggregation) mode, multiple BWPs can be configured for the UE. Among them, the UE can be configured with multiple BWPs, but at most only one BWP can be activated at a certain time.

MBMS: It is a service introduced in 3GPP (Third Generation Partnership Project) R6. MBMS is a technology that transfers data from one data source to multiple user devices by sharing network resources. It can effectively utilize network resources while providing multimedia services to achieve higher-rate multimedia service broadcast and multicast. Among them, due to the low spectrum efficiency of MBMS in 3GPP R6, it is not enough to effectively carry and support the operation of mobile TV-type services. Therefore, in the wireless access network LTE (Long Term Evolution, long-term evolution standard) project, 3GPP clearly proposed enhancements The ability to support downlink high-speed multimedia broadcast and multicast services, and to determine the design requirements for the physical layer and air interface. With the development of communication technology, R9 has introduced E-MBMS (Enhanced-Multimedia Broadcast Multicast Service, enhanced multimedia broadcast multicast service) technology, E-MBMS proposed the concept of SFN (Single Frequency Network, single frequency network), That is, a uniform frequency is used to send data in all cells at the same time, but synchronization between cells must be ensured. This method can greatly improve the overall signal-to-noise ratio distribution of the cell, and the spectrum efficiency will be greatly improved accordingly. In addition, in LTE or LTE-A (Long Term Evolution-Advanced, Enhanced Long Term Evolution), MBMS only has a broadcast bearer mode, not a multicast bearer mode.

Next, the application scenarios involved in this application are briefly introduced.

Since the UE can support the reception of broadcast services and the reception of unicast services, there may be a scenario where the bandwidth of the downlink BWP currently activated by the UE does not overlap with the bandwidth of the received broadcast service, for example, As shown in Figure 1, the horizontal axis represents the BWP configuration of the UE, and the vertical axis represents the bandwidth distribution of the configured BWP. If the currently activated downlink BWP is BWP1 and there is no MBMS related configuration on this BWP1, at this time, if the UE needs to receive MBMS service data, because there is no MBMS related configuration on the currently activated downlink BWP1, it cannot receive MBMS service data. If the UE automatically switches to another BWP with MBMS-related configuration to receive MBMS service data, it may be that the network device does not know that the UE has switched the BWP, causing the network device to continue to single out the UE on the currently activated downlink BWP1. Broadcast scheduling, thereby wasting resources. To this end, an embodiment of the present application provides a data receiving method, which can solve the above-mentioned problems.

In addition, a brief introduction to the implementation environment involved in this application is given.

Please refer to FIG. 2, which is a schematic diagram showing an implementation environment according to an exemplary embodiment. The implementation environment mainly includes a UE 210 and a network device 220. The UE 210 can communicate with the network device 220 through the communication network. The UE 210 can perform operations such as data reception according to the method provided in the embodiments of the present application. The UE 210 is any device capable of data transmission. In some implementations, In the example, the network device may be a device such as a base station, which is not limited in the embodiment of the present application.

After introducing the technical terms, application scenarios, and implementation environment involved in this application, the data receiving method provided by the embodiments of this application will be described in detail in the following with reference to the accompanying drawings.

Please refer to FIG. 3, which is a flowchart of a data receiving method according to an exemplary embodiment. The method can be applied to the implementation environment shown in FIG. 2 and executed by the UE. The method may include The following steps:

Step 301: When there is a data reception requirement for the MBMS service, if the currently activated downlink BWP is not configured with the MBMS service channel, send a first message, which is used to indicate that the UE currently needs to switch the downlink BWP to receive the MBMS Business data.

The network device may configure the BWP for the UE in advance, and the BWP configured by the network device for the UE may include an uplink BWP and a downlink BWP. Among them, each UE can configure multiple uplink BWPs, for example, it can be 4 at most, and each UE can configure multiple downlink BWPs, for example, it can also be 4 at most.

In addition, one or more downlink BWPs configured for the UE may also be configured with MBMS service channels, that is, the bandwidth of the one or more downlink BWPs may overlap with the bandwidth of receiving the MBMS service. Alternatively, the one or more downlink BWPs configured for the UE may not be configured with the channel of the MBMS service, that is, the bandwidth of the one or more downlink BWPs may not overlap with the bandwidth of receiving the MBMS service.

It should be noted that the aforementioned MBMS service channel may be a control channel or a data channel, which is not limited in the embodiment of the present application.

The currently activated downlink BWP is usually activated by the network equipment, that is, if the UE needs to receive data, the network equipment can activate a certain downlink BWP configured for the UE according to the throughput of the UE, and the downlink BWP may be configured with MBMS services The channel may not be configured with MBMS service.

Wherein, the reception of the MBMS service can usually be triggered by the user. For example, when the user wants to listen to the broadcast, the UE can be triggered to receive the MBMS service. Alternatively, the reception of the MBMS service may also be automatically triggered by the UE. For example, the UE may periodically start the reception operation of the MBMS service.

When there is a data reception requirement for the MBMS service, if the currently activated downlink BWP is not configured with a channel for the MBMS service, the data for the MBMS service cannot be received on the downlink BWP, so it is necessary to switch to the downlink BWP configured with the channel for the MBMS service , In order to receive the data of the MBMS service. In order to prevent the network device from still unicast scheduling on the currently activated downlink BWP, the UE sends a first message to the network device to notify the network device that the downlink BWP needs to be switched to receive MBMS service data through the first message. In this way, after receiving the first message, the network device may no longer perform unicast scheduling on the UE.

As an example, the UE may send the first message on the currently activated uplink BWP.

As an example, the first message may include the following possible situations:

The first case: the first message is an indication message of the physical layer.

That is, the first message may be an indication message from the physical layer, or in other words, the first message may be transmitted through the physical layer.

Exemplarily, the first message is a designated SR (Scheduling Request), and the designated SR may be a specific SR of the physical layer. For example, the designated SR may correspond to a specific SR ID (Identification), so as to identify that the transmission of the designated SR is to indicate that the UE has a data reception requirement of the MBMS service. For another example, the designated SR may also be transmitted through a designated resource. In this way, when the network device receives the designated SR from the designated resource, it can be determined that the UE has a data reception requirement for the MBMS service.

The second case: the first message is a MAC (Media Access Control, media access control) layer control message.

That is, the first message may be a control message from the MAC layer, or in other words, the first message may be transmitted through the MAC layer. For example, the first message is MAC CE (Control Element, control element).

The third case: the first message is an RRC (Radio Resource Control, radio resource control) layer message.

In other words, the first message may be a message from the RRC layer, or in other words, the first message may be transmitted through the RRC layer.

As an example, the first message also carries type indication information, and the type indication information is used to indicate the data type of the MBMS service.

That is, the UE can notify the network device of the data type of the MBMS service to be received. For example, if the first message is a designated SR from the physical layer, the designated SR can carry the type indication information; for another example, if the first message is a MAC CE from the MAC layer, the MAC CE can carry The type indication information; for another example, if the first message is a message from the RRC layer, the RRC layer message may carry the type indication information. In this way, the network device can be notified of the data type of the MBMS service that needs to be requested currently.

Step 302: Switch from the currently activated downlink BWP to the target downlink BWP, where the target downlink BWP is the downlink BWP configured with the channel of the MBMS service.

As an example, the UE determines the target downlink BWP, that is, determines which BWP needs to be switched to to receive the data of the MBMS service, and then can switch from the currently activated downlink BWP to the determined target downlink BWP.

In a possible implementation of the present application, the UE may determine the target downlink BWP (for example, randomly selected) according to a certain strategy, and then switch to the target downlink BWP. That is, after the UE sends the first message, it determines the target downlink BWP according to a certain strategy, and automatically switches to the target downlink BWP.

In another possible implementation manner of this application, after the UE sends the first message, it can start the configured timer, and determine the target downlink BWP according to the feedback of the network device within the timing window of the timer. The specific implementation can be Including the following possible ways:

As an example: if the BWP switching instruction is received within a specified time period, the target downlink BWP is determined based on the BWP identifier carried in the BWP switching instruction.

The specified duration can be set according to actual needs, for example, it can be instructed by a network device, or it can also be set by default by the UE, which is not limited in this embodiment of the application.

Among them, the BWP identifier can be used to uniquely identify a BWP.

After the UE sends the first message, it can start a timer to start counting, and receive the BWP switching instruction in a window of a specified duration. If the BWP switching instruction of the network device is received within the specified time period, the downlink BWP indicated by the BWP identifier carried in the BWP switching instruction may be determined as the target downlink BWP.

That is, after receiving the first message, the network device can select a BWP from the BWP configured for the UE and configured with the channel of the MBMS service, and then generate a BWP switching instruction based on the selected BWP identifier of the BWP, And send the generated BWP handover instruction to the UE. In this way, the UE can determine the target downlink BWP according to the indication of the network device.

As another example: if the BWP switching instruction is not received within the specified time period, the target downlink BWP is determined according to the specified strategy.

Among them, the specified strategy can be set according to actual needs. For example, the designated policy may be instructed by the network device, or the designated policy may also be set by the UE by default. As an example, the specified strategy may be determined according to parameters such as the data type and data volume of the MBMS service to be received. For example, if the data volume of the MBMS service is relatively large, the specified bandwidth threshold may be greater than the specified bandwidth threshold and configured with The downlink BWP of the channel of the MBMS service is determined as the target downlink BWP. Wherein, the specified bandwidth threshold can be set according to actual needs, for example, it can be instructed by the network device, or it can be set by default by the terminal device. As another example, the designated strategy may also be a random selection strategy, which is not limited in the embodiment of the present application.

After the UE sends the first message, it can start a timer to start counting, and receive the BWP switching instruction in a window of a specified duration. If the BWP switching instruction is not received within the specified time period, a downlink BWP can be determined as the target BWP from the configured BWPs of channels configured with MBMS services according to the specified strategy. For example, a BWP configured with an MBMS service channel can be randomly selected as the target BWP.

Of course, if there is only one BWP configured and configured with the channel of the MBMS service, the only BWP can be directly determined as the target BWP.

Further, when the UE switches the downlink BWP, it can also switch the uplink BWP, which specifically may include the following two possible implementation manners:

As an example, in TDD (Time Division Duplex) mode, switching from the currently activated uplink BWP to the first uplink BWP, the first uplink BWP and the target downlink BWP have the same BWP identifier, and The first uplink BWP is configured with feedback resources for transmitting feedback data of the MBMS service.

In the TDD mode, the uplink BWP and the downlink BWP exist in pairs, that is, a UE can be configured with up to 4 BWP pairs, and the BWP identifiers of the uplink BWP and the downlink BWP in each BWP pair are the same. Therefore, when switching the uplink BWP, switch from the currently activated uplink BWP to the first uplink BWP with the same BWP identifier as the target downlink BWP, and the first uplink BWP is configured with feedback resources for transmitting feedback data of the MBMS service.

Wherein, the feedback data may include ACK (acknowledgement response) or NACK (negative response), ACK is used to indicate successful reception of MBMS service data, and NACK is used to indicate unsuccessful reception of MBMS service data. That is, after the UE receives the data of the MBMS service, it can send feedback data to the network device according to the actual reception situation. Since the feedback resource is required to send the feedback data, the first uplink BWP after the handover needs to be configured to transmit MBMS Feedback resources for business feedback data.

As another example, in the FDD (Frequency Division Duplex) mode, switching from the currently activated uplink BWP to the second uplink BWP, and the second uplink BWP is configured with feedback data for transmitting MBMS services Feedback resources.

In the FDD mode, the BWP identifier of the second uplink BWP may be different from the BWP identifier of the target downlink BWP, but the second uplink BWP needs to be configured with feedback resources for transmitting the feedback data of the MBMS service, so that the UE can pass The feedback resource sends feedback data of the MBMS service to the network device.

In the embodiment of the present application, when there is a demand for data reception of the MBMS service, if the currently activated downlink BWP is not configured with the channel of the MBMS service, in order to be able to receive the MBMS service, it is necessary to switch to the target downlink BWP configured with the channel of the MBMS service. In order to facilitate the network equipment to be able to know, the first message is sent through which the UE currently needs to switch the downlink BWP to receive the data of the MBMS service. In this way, the network device can be prevented from continuing to unicast scheduling on the currently activated BWP, thereby saving network resources.

For ease of understanding, the method provided by this application will be introduced with a specific example. Please refer to Figure 4, where the horizontal axis represents the BWP configuration of the UE, and the vertical axis represents the bandwidth distribution of the configured BWP. It is assumed that the UE is configured with three For the downlink BWP, 3 uplink BWPs are configured at the same time.

The configured downlink BWP includes downlink BWP1, downlink BWP2, and downlink BWP3. The downlink BWP1 is not configured to receive MBMS-related configuration information, that is, the downlink BWP1 is not configured with a channel for MBMS services; the downlink BWP2 is configured to receive MBMS-related configuration information, That is, the downlink BWP2 is configured with an MBMS service channel; the downlink BWP3 is configured with relevant configuration information for receiving MBMS, that is, the downlink BWP3 is configured with an MBMS service channel.

Among them, the configured uplink BWP are uplink BWP1, uplink BWP2, and uplink BWP3 respectively; if it is a TDD system, according to the current BWP working mode, the uplink and downlink BWP identifiers are the same. For example, if the activated downlink BWP is 2, then activate The upstream BWP also needs to be 2. If it is an FDD system, there is no such restriction. Among them, the uplink BWP2 is configured with feedback resources that can transmit the feedback data of the MBMS service, and the uplink BWP3 is configured with feedback resources that can transmit the feedback data of the MBMS service.

The downlink BWP currently activated by the UE is the downlink BWP1, that is, the UE can receive the scheduling information and data of the unicast service on the downlink BWP1.

At a certain moment, when the UE needs to receive the broadcast service, that is, when it needs to receive the data of the MBMS service, the UE sends the first message on the currently activated uplink BWP1, which indicates that the UE needs to switch the downlink BWP to receive the MBMS service. .

As an example, the first message may be an indication information triggered by the MAC layer to be sent on physical layer resources. For example, it may be a designated SR. The designated SR may correspond to a special SR ID or configuration, so that the network device can It can be distinguished that the designated SR is the data of the UE requesting to switch the downlink BWP to receive the MBMS service. For example, the network can configure a dedicated SR ID corresponding to the UE’s MBMS service request, that is, when the UE has MBMS service data reception requirements, and the current downlink BWP does not have the relevant configuration of the MBMS service, the UE An SR (that is, a designated SR) can be triggered, and the resource corresponding to the dedicated SR ID can be used to send the designated SR.

As another example, the first message may be a MAC layer control information, such as MAC CE, and the MAC CE may notify the network device UE of the data type of the MSMB service that needs to be requested.

As another example, the indication signaling may also be an RRC layer message.

After the UE sends the first message to the network device, the network device no longer unicasts the UE on the downlink BWP1.

After sending the first message, the UE can automatically switch to the target downlink BWP to receive the data of the MBMS service, for example, automatically switch to the downlink BWP2 to receive the data of the MBMS service.

Optionally, after the UE sends the first message, it can start a pre-configured timer, and receive the BWP handover signaling of the network device within a window of the specified duration of the timer.

If the UE does not receive the BWP switching instruction sent by the network device within the specified time window, the UE determines the target downlink BWP according to the specified strategy, and switches to the target downlink BWP to receive broadcast data. For example, the UE determines the downlink BWP2 as the target downlink BWP, and then switches from the downlink BWP1 to the downlink BWP2.

If the UE receives the BWP switching instruction sent by the network device within the specified time window, the UE determines the target downlink BWP according to the BWP identifier carried in the BWP switching instruction, and switches to the target downlink BWP to receive broadcast data. For example, assuming that the BWP identifier carried in the BWP handover instruction is 2, the UE determines the downlink BWP2 as the target downlink BWP and switches to the downlink BWP2.

Further, when the UE switches to the target downlink BWP to receive broadcast data, the UE switches the currently activated uplink BWP to the target BWP, and the target uplink BWP is configured with feedback resources for transmitting feedback data of the MBMS service.

Exemplarily, if it is working in the TDD mode, assuming that the target downlink BWP is the downlink BWP2, the UE switches from the current uplink BWP1 to the uplink BWP2.

For another example, if it is working in FDD mode, the BWP identifier of the switched uplink BWP may be different from the BWP identifier of the target downlink BWP. For example, the UE may switch from the current uplink BWP1 to the uplink BWP3.
