Description

Information feedback and resource allocation method and related product

Technical Field

The present application relates to the field of communications technologies, and in particular, to an information feedback method, a resource allocation method, and a related product.

Background

With the development of communication technology, Multimedia Broadcast Multicast Service (MBMS) will be introduced into New Radio (NR), and a Single Cell Point To multipoint (SC-PTM) transmission mechanism will be adopted, that is, each Cell independently schedules the transmission of the MBMS. However, the current mbms service in new wireless networks does not introduce a feedback mechanism, so the transmission performance and effect of the mbms service are poor.

Disclosure of Invention

The embodiment of the application discloses an information feedback method, a resource allocation method and a related product, aiming at improving the transmission performance and effect of a multimedia broadcast multicast service by introducing a feedback mechanism.

A first aspect of an embodiment of the present application discloses an information feedback method, which is applied to a network device, and the method includes: the method comprises the steps of sending multimedia broadcast multicast MBMS service information to a terminal, and sending feedback condition information and/or feedback type information to the terminal, wherein the feedback condition information is used for indicating whether the terminal implements feedback, and the feedback type information is used for determining information fed back by the terminal; and receiving feedback information from the terminal.

As can be seen, in this example, the network device sends the MBMS service information to the terminal, and sends feedback condition information and/or feedback type information indicating that the terminal implements feedback to the terminal, so that the network device can indicate whether the terminal needs to feed back and what information is specifically fed back, which is beneficial to improving the transmission performance and effect of the multimedia broadcast multicast service.

In one possible example, the feedback condition information is used to instruct the terminal to perform feedback when at least one of the following conditions is satisfied: the channel condition of the channel is greater than a first preset threshold; the channel condition of the channel is smaller than a second preset threshold; in one or more of a connected state, an idle state, and an inactive state.

It can be seen that, in this example, the network device may send a trigger condition for implementing feedback to the terminal, and when the terminal meets the trigger condition, the terminal feeds back information to the network device instead of implementing feedback by any terminal in the cell, thereby being beneficial to avoiding resource conflict caused by insufficient feedback resource configuration.

In one possible example, the feedback type information is used to determine that the terminal feeds back at least one of the following information: state information of a channel in which the terminal is located; receiving result information of the MBMS information by the terminal; the terminal is interested in target MBMS service information, the MBMS service information comprises A pieces of MBMS service information, the target MBMS service information is at least one of the A pieces of MBMS service information, and A is an integer larger than 0.

In this example, it can be seen that, in the present example, the network device sends the MBMS service information to the terminal, and the terminal feeds back the reception condition of the MBMS service information to the network device, and if the terminal does not correctly receive the MBMS service information, the network device can retransmit the MBMS service information to the terminal, thereby ensuring that the terminal receives the MBMS service information, and being beneficial to improving the transmission performance and effect of the multimedia broadcast multicast service; after the network equipment sends the MBMS information to the terminal, the terminal feeds back the state information of the channel where the terminal is located to the network equipment, so that the network equipment can acquire the channel states of different terminals, and the modulation and coding strategy is determined in a targeted manner to send the MBMS information, thereby improving the transmission spectrum efficiency; the network equipment sends a plurality of pieces of MBMS information to the terminal, and the terminal can feed back which one or more pieces of MBMS information are interested to the network equipment, so that the network equipment can know which MBMS information are interested to the terminal, and then the network equipment can pertinently send the interested types of MBMS information to the terminal, thereby improving the user experience of terminal users.

In one possible example, the terminal includes B terminals, where B is an integer greater than or equal to 1, and the receiving feedback information from the terminal includes: receiving first feedback information transmitted by C terminals in the B terminals through a first feedback resource, wherein C is an integer which is greater than or equal to 0 and less than or equal to B; determining a second feedback resource according to the first feedback information; and receiving second feedback information transmitted by the second feedback resource from D terminals in the B terminals, wherein the D terminals do not include any one of the C terminals, and D is an integer greater than or equal to 0 and less than or equal to B.

It can be seen that, in this example, the network device sends the MBMS service information to the terminals in the serving cell, because the network device does not know the number of terminals in the serving cell, it is unable to accurately configure the feedback resources for the terminals to send feedback information, it is considered that all terminals in the serving cell that need to be fed back feed back are fed back in two stages, the network device first configures the feedback resources fed back in the first stage, a part of the terminals first feeds back information on the feedback resources configured in the first stage, the network device can know the number of terminals that need to be fed back according to the information fed back in the first stage, and reconfigures the feedback resources for the second stage feedback, and the remaining terminals feed back on the reconfigured feedback resources, thereby facilitating reasonable configuration of the feedback resources and avoiding resource waste and resource collision.

In one possible example, the first feedback resource is determined according to a coverage area of a cell served by the network device and/or an activity level of the B terminals.

As can be seen, in this example, the network device initially configures the feedback resource fed back in the first stage according to the coverage area of the serving cell and/or the activity level of the terminal in the serving cell, which is beneficial to reasonably configuring the feedback resource.

In one possible example, the receiving the first feedback information transmitted from the C terminals of the B terminals through the first feedback resource includes: sending a system message or first single cell MBMS point-to-multipoint control channel (SC-MCCH) information to the B terminals, wherein the system message or the first SC-MCCH information is used for configuring the first feedback resources and determining the C terminals which perform feedback on the first feedback resources from the B terminals; and C pieces of first feedback information transmitted by the C pieces of terminals through the first feedback resources are received, wherein the C pieces of terminals correspond to the C pieces of first feedback information one by one.

It can be seen that, in this example, the network device configures a feedback resource fed back in a first stage to the terminal in the serving cell by sending a system message or first Single cell MBMS point-to-multipoint Control Channel (SC-MCCH) information, and selects a terminal fed back in the first stage from the terminals in the serving cell by sending the system message or the SC-MCCH information, and then the terminals fed back in the first stage respectively send a piece of feedback information to the network device, so that the network device can determine the terminal fed back in the feedback resource fed back in the first stage, thereby avoiding contention among multiple terminals on the same feedback resource fed back in the first stage, and facilitating reasonable resource configuration.

In one possible example, the system message or the first SC-MCCH information comprises a modulo-valued parameter or scaling factor.

It can be seen that, in this example, the network device sends the modulo-value parameter or the scaling factor to the terminal, and the modulo-value parameter or the scaling factor can be used to determine the terminal fed back in the first stage, which is beneficial to determining the corresponding relationship between the feedback resource and the terminal, and improving the rationality of resource allocation.

In one possible example, the determining the C terminals from the B terminals to feed back on the first feedback resource includes: performing modulo operation on the IDs of the B terminals according to the parameter which is taken in modulo mode so as to determine the C terminals which perform feedback on the first feedback resource from the B terminals; or determining the C terminals which perform feedback on the first feedback resource from the B terminals according to the scale factor.

In this example, the terminal performs modulo operation on the ID according to the parameter that is evaluated in modulo mode, and determines whether to feed back in the first stage, thereby determining the number of terminals fed back in the first stage; or determining the number of the terminals fed back in the first stage according to the scale factor; the number of the terminals fed back in the first stage is selected from all the terminals in the serving cell for feedback, so that the network equipment can determine the number of the terminals fed back in the first stage, the number of the terminals fed back in the first stage does not exceed the number of the resources fed back in the first stage, resource conflict is avoided, and information feedback efficiency is improved.

In one possible example, the sending the system message or the first SC-MCCH information to the B terminals includes: if the feedback information is the receiving result of the terminal to the MBMS information, first SC-MCCH information is sent to the B terminals; and if the feedback information is the target MBMS information which is interested by the terminal, sending a system message to the B terminals.

It can be seen that, in this example, when the feedback information is a reception result of the terminal for the MBMS service information, the feedback resource fed back at the first stage is configured and the terminal fed back at the first stage is determined through the SC-MCCH information; when the feedback information is the target MBMS service information which is interested by the terminal, the feedback resource fed back by the first stage is configured and the terminal fed back by the first stage is determined, and different feedback information adopts different information to configure the feedback resource fed back by the first stage and determine the terminal fed back by the first stage, so that the information transmission performance and effect are favorably improved.

In one possible example, the receiving C first feedback information transmitted from the C terminals through the first feedback resource includes: receiving C first feedback information transmitted by the C terminals on C resource positions, wherein the C terminals correspond to the C resource positions one by one, the first feedback resources comprise the C resource positions, and the corresponding relation between the C terminals and the C resource positions is determined according to the identification of the terminals and/or the index of the beam of the service terminal.

It can be seen that in this example, the feedback resource has multiple resource locations, each resource location may be used to transmit one feedback information, and the mapping relationship between the terminal and the resource location is determined by the identifier of the terminal and/or the index of the beam of the service terminal, so that when the terminal sends the feedback information to the network device, the terminal may find the corresponding resource location according to the mapping relationship to transmit the feedback information, and the network device receives the feedback information of different terminals in order, which is beneficial to improving the efficiency of information transmission.

In one possible example, the determining a second feedback resource according to the first feedback information includes: adjusting the number of feedback resources according to the first feedback information to obtain the second feedback resource; or adjusting the mapping relation between the feedback resources and the synchronous signal blocks according to the first feedback information to obtain the second feedback resources.

As can be seen, in this example, the network device may determine, according to the received information fed back in the first stage, the number of terminals that need to be fed back in the serving cell and the number of terminals that feed back the service in the first stage of the feedback resource associated with each synchronization signal block, so as to dynamically adjust the number of the feedback resources, or adjust the mapping relationship between the feedback resources and the synchronization signal blocks, thereby avoiding excessive or insufficient allocation of the feedback resources and uneven allocation.

In one possible example, the pre-configuring, by the network device, third feedback resources for implementing feedback by the D terminals, and adjusting the number of the feedback resources according to the first feedback information to obtain second feedback resources includes: determining the number of terminals to be fed back according to the first feedback information; if the number of the terminals to be fed back is not greater than a preset threshold, reducing resource positions on the third feedback resource to obtain the second feedback resource; and if the number of the terminals to be fed back is greater than the preset threshold value, increasing the resource position on the third feedback resource to obtain the second feedback resource.

As can be seen, in this example, the network device may determine, according to the received information fed back in the first stage, the number of terminals that need to be fed back in the serving cell, and when the number of terminals that need to be fed back is small, the number of feedback resources fed back in the second stage may be reduced; when the number of the terminals needing to be fed back is large, the number of feedback resources fed back in the second stage can be increased; therefore, the quantity of the feedback resources can be dynamically adjusted, and resource waste caused by excessive allocation of the feedback resources or resource conflict caused by insufficient allocation of the feedback resources is avoided.

In one possible example, a resource location of the first feedback resource is configured on a plurality of beams, each beam is associated with at least one synchronization signal block, each synchronization signal block is associated with a different resource location, and the adjusting a mapping relationship between a feedback resource and a synchronization signal block according to the first feedback information to obtain a second feedback resource includes: determining the number of terminals served by each beam according to the first feedback information; and adjusting the mapping relation between the resource position and the synchronous signal block according to the number of the terminals served by each beam to obtain the second feedback resource.

It can be seen that, in this example, the network device implements full coverage of the serving cell through multiple beams, each beam corresponds to one synchronization signal block, each synchronization signal block is associated with a different resource location, and when the number of terminals served by different beams is greatly different, the mapping relationship between the resource location and the synchronization signal block can be adjusted, so as to dynamically adjust the feedback resource, and make the feedback resource fully utilized.

In one possible example, the receiving the second feedback information transmitted from the D terminals in the B terminals through the second feedback resource includes: sending second SC-MCCH information or downlink control information DCI to the B terminals, wherein the second SC-MCCH information or the DCI is used for configuring the second feedback resources and determining the D terminals which perform feedback on the second feedback resources from the B terminals; and receiving D pieces of second feedback information transmitted by the D pieces of terminals through the second feedback resources, wherein the D pieces of terminals correspond to the D pieces of second feedback information one by one.

It can be seen that, in this example, the network device configures feedback resources fed back at the second stage to the terminals in the serving cell by sending the second SC-MCCH information or the downlink control information, and optionally selects the terminals fed back at the second stage from the terminals in the serving cell by sending the second SC-MCCH information or the downlink control information, and then the terminals fed back at the second stage send a piece of feedback information to the network device, so that the network device can reasonably configure the feedback resources fed back at the second stage according to the feedback condition fed back at the first stage and determine the terminals corresponding to the feedback resources fed back at the second stage, thereby avoiding configuring excessive feedback resources, avoiding competition of multiple terminals on the feedback resources fed back at the same second stage, and facilitating reasonable resource configuration.

In one possible example, the terminal includes B terminals, where B is an integer greater than or equal to 1, and the receiving feedback information from the terminal includes: receiving first feedback information transmitted on a first time slot through a first feedback resource from E terminals in the B terminals, wherein E is an integer greater than 0 and less than or equal to B; and receiving second feedback information transmitted on a second time slot by the first feedback resource from other E terminals in the B terminals, wherein the other E terminals are E terminals except the E terminals in the B terminals.

It can be seen that, in this example, the network devices distribute according to time when setting the feedback resources, so that the terminals that need to feedback perform feedback in an average batch manner within a period of time, rather than feedback together, and one terminal only performs feedback once, thereby facilitating reasonable allocation of the feedback resources and avoiding resource conflicts.

The second aspect of the embodiment of the present application discloses an information feedback method, including: a terminal receives MBMS service information from network equipment, and the terminal receives feedback condition information and/or feedback type information from the network equipment, wherein the feedback condition information is used for indicating whether the terminal implements feedback, and the feedback type information is used for determining the information fed back by the terminal; and the terminal sends feedback information to the network equipment.

In one possible example, the terminal includes B terminals, where B is an integer greater than or equal to 1, and the terminal sends feedback information to the network device, where the method includes: c terminals in the B terminals transmit first feedback information to the network equipment through first feedback resources, wherein C is an integer which is greater than or equal to 0 and less than or equal to B; d terminals in the B terminals transmit second feedback information to the network equipment through second feedback resources, wherein the second feedback resources are determined by the network equipment according to the first feedback information, the D terminals do not include any of the C terminals, and D is an integer greater than or equal to 0 and less than or equal to B.

In one possible example, the transmitting, by C terminals of the B terminals, first feedback information to the network device through a first feedback resource includes: the B terminals receive a system message or first SC-MCCH information from the network equipment, and the system message or the first SC-MCCH information is used for configuring the first feedback resource and determining the C terminals which perform feedback on the first feedback resource from the B terminals; and the C terminals transmit C pieces of first feedback information to the network equipment through the first feedback resources, and the C terminals correspond to the C pieces of first feedback information one by one.

In one possible example, the B terminals receive a system message or first SC-MCCH information from the network device, including: if the feedback information is the receiving result of the terminal to the MBMS service information, the B terminals receive first SC-MCCH information from the network equipment; and if the feedback information is the target MBMS information which is interested by the terminal, the B terminals receive the system information from the network equipment.

In one possible example, the C terminals transmit C first feedback information to the network device through the first feedback resource, including: the C terminals transmit C first feedback information to the network equipment at C resource positions, the C terminals correspond to the C resource positions one by one, the first feedback resources comprise the C resource positions, and the corresponding relation between the C terminals and the C resource positions is determined according to the identification of the terminals and/or the index of the beam of the service terminal.

In one possible example, the second feedback resource is obtained by the network device adjusting the number of feedback resources according to the first feedback information; or the second feedback resource is obtained by the network device adjusting the mapping relation between the feedback resource and the synchronization signal block according to the first feedback information.

In one possible example, the second feedback resource is obtained by the network device performing the following operations: determining the number of terminals to be fed back according to the first feedback information; if the number of the terminals to be fed back is not greater than a preset threshold value, reducing resource positions on a third feedback resource, wherein the third feedback resource is pre-configured by the network equipment for the D terminals to implement feedback; and if the number of the terminals to be fed back is greater than the preset threshold value, increasing the resource position on the third feedback resource.

In one possible example, the resource locations of the first feedback resource are configured on a plurality of beams, each beam is associated with at least one synchronization signal block, each synchronization signal block is associated with a different resource location, and the second feedback resource is obtained by the network device by: determining the number of terminals served by each beam according to the first feedback information; and adjusting the mapping relation between the resource position and the synchronous signal block according to the number of the terminals served by each beam.

In one possible example, D terminals of the B terminals transmit second feedback information to the network device through a second feedback resource, including: the B terminals receive second SC-MCCH information or Downlink Control Information (DCI) from the network equipment, wherein the second SC-MCCH information or the DCI is used for configuring the second feedback resources and determining the D terminals which perform feedback on the second feedback resources from the B terminals; and the D terminals transmit D pieces of second feedback information to the network equipment through the second feedback resources, and the D terminals correspond to the D pieces of second feedback information one by one.

In one possible example, the terminal includes B terminals, where B is an integer greater than or equal to 1, and the terminal sends feedback information to the network device, where the method includes: e terminals in the B terminals transmit first feedback information to the network equipment on a first time slot through first feedback resources, wherein E is an integer which is greater than 0 and less than or equal to B; and transmitting second feedback information to the network device at a second time slot by using the first feedback resource through other E terminals in the B terminals, wherein the other E terminals are E terminals except the E terminals in the B terminals.

A third aspect of the embodiments of the present application discloses a resource configuration method, which is applied to a network device, and the method includes: sending first configuration information, wherein the first configuration information is used for configuring first feedback resources; receiving first feedback information transmitted by a first terminal through the first feedback resource, wherein the first feedback information is used for the first terminal to implement feedback on the MBMS service; and sending second configuration information, wherein the second configuration information is used for configuring a second feedback resource, the second feedback resource is used for a second terminal to transmit second feedback information, and the second feedback information is used for the second terminal to implement feedback on the MBMS.

As can be seen, in this example, since the network device does not know how many terminals in the cell need to perform feedback at first, feedback resources for implementing feedback by the terminals cannot be accurately configured, and if too many feedback resources are configured, the feedback resources are wasted; if the feedback resource allocation is too little, the resource conflict is serious; therefore, a set of two-stage feedback mechanism can be designed, the network equipment configures a part of feedback resources to enable a part of terminals to implement feedback, and after receiving the feedback of the part of terminals, the network equipment configures another part of feedback resources to enable another part of terminals to implement feedback; therefore, the network equipment can configure reasonable feedback resources for implementing feedback of the terminal aiming at the MBMS service.

In one possible example, the sending the second configuration information includes: determining the second feedback resource according to the first feedback information; and sending the second configuration information.

In one possible example, the determining the second feedback resource according to the first feedback information includes: adjusting the number of feedback resources according to the first feedback information to obtain the second feedback resource; or adjusting the mapping relation between the feedback resources and the synchronous signal blocks according to the first feedback information to obtain the second feedback resources.

In one possible example, the pre-configuring, by the network device, a third feedback resource for implementing feedback by the second terminal, and adjusting the number of feedback resources according to the first feedback information to obtain a second feedback resource includes: determining the number of terminals to be fed back according to the first feedback information; if the number of the terminals to be fed back is not greater than a preset threshold, reducing resource positions on the third feedback resource to obtain the second feedback resource; and if the number of the terminals to be fed back is greater than the preset threshold value, increasing the resource position on the third feedback resource to obtain the second feedback resource.

Fig. 1 is a schematic diagram of a communication system according to an embodiment of the present application. The communication system in fig. 1 may include at least one terminal (e.g., terminal 1, terminal 2) and a network device. The network device is used for providing communication service for the terminal and accessing the core network, and the terminal can access the network by searching the synchronous signal, the broadcast signal and the like sent by the network device, so as to communicate with the network. The terminal may receive configuration information or system information, etc. from the network device. It should be understood that the network devices included in the communication system may be one or more. A network device may send data or control signaling to one or more terminals. Multiple network devices may also transmit data or control signaling to one or more terminals simultaneously.

In order to improve the transmission performance and effect of the MBMS service, the network device may set the terminal to perform feedback for some MBMS services. If the terminals in different states need to feed back simultaneously, the shortage of feedback resources is easily caused. Because the network equipment does not know how many terminals will feed back, if too many feedback resources are configured, resource waste occurs; if the feedback resource configuration is too small, the resource conflict is serious. Therefore, a set of feedback mechanism needs to be designed, so that the network device can configure a reasonable feedback resource for the terminal to perform feedback for the MBMS service.

The technical solutions provided in the present application are described in detail below with reference to specific embodiments.

Referring to fig. 2, fig. 2 is a method for feeding back information according to an embodiment of the present disclosure, which includes, but is not limited to, the following steps:

step 201, a network device sends multimedia broadcast multicast MBMS service information to a terminal, and sends feedback condition information and/or feedback type information to the terminal, where the feedback condition information is used to indicate whether the terminal implements feedback, and the feedback type information is used to determine information fed back by the terminal.

The terminal can acquire the multicast data or the multicast information to be broadcasted, and meanwhile, the network equipment can indicate whether the terminal implements feedback and what information is fed back through feedback condition information and/or feedback type information.

For example, the Network device may be a base station of an NR cell, the terminal is a UE of the NR cell, and during a period (e.g. 40 ms), the base station of the NR cell needs to transmit 3 MBMS services, which are respectively referred to as session 1(session1), session 2(session2), and session 3(session3), the base station of the NR cell schedules transmission of the MBMS services for 6 times in total during the period, each session transmits for 2 times, the base station of the NR cell schedules a time slot in which each session is located, and then notifies a User Equipment (UE) of scheduling information through an SC-MCCH to a list of all MBMS services transmitted on an SC-MTCH, where the list includes a Temporary Mobile Group Identity (TMGI), a session Identity, a Radio Network Temporary identifier (Group-Identity, G-RNTI) of each MBMS service and scheduling information.

Step 202, the terminal receives MBMS service information from the network device, and the terminal receives feedback condition information and/or feedback type information from the network device.

For example, the UE acquires the G-RNTI of the MBMS service of interest through the SC-MCCH Information, and then detects Downlink Control Information (DCI) scrambled by the G-RNTI in a corresponding timeslot according to the scheduling Information, thereby acquiring multicast data transmitted on a Downlink Shared Channel (dl Shared Channel).

Step 203, the terminal sends feedback information to the network device.

The terminal may feed back a reception result of the MBMS service information, where the reception result of the MBMS service information by the terminal includes correct reception (ACK) and incorrect reception (NACK).

For example, when the UE does not receive the MBMS service information sent by the base station of the NR cell or does not acquire the multicast data from the MBMS service information, the UE may feed back the result of incorrect reception to the base station; when the UE receives MBMS service information sent by the base station of the NR cell or acquires multicast data from the MBMS service information, a result of correct reception may be fed back to the base station.

Step 204, the network device receives the feedback information from the terminal.

If the feedback information is not received correctly, the network device may resend the MBMS service information according to the circumstances.

Specifically, the network device may set the condition for implementing feedback by the terminal to be fed back, that is, the channel condition of the terminal to be fed back reaches a certain condition, the state of the terminal to be fed back is in a certain state, and the like. For example, a terminal with a channel condition exceeding a preset threshold may be set for feedback, or a terminal with a channel condition lower than the preset threshold may be set for feedback. For another example, the terminal set by the network device in a specific state needs to implement feedback, and the specific state includes one or more of a connected state, an idle state, and an inactive state.

For example, the network device sends the MBMS service information to the terminal, and the terminal feeds back the reception status of the MBMS service information to the network device, and if the terminal does not correctly receive the MBMS service information, the network device may retransmit the MBMS service information to the terminal, thereby ensuring that the terminal receives the MBMS service information, and facilitating to improve the transmission performance and effect of the multimedia broadcast multicast service.

For another example, the base station of the NR cell sends a plurality of MBMS service information to the UE in the serving cell, and the UE may feed back the MBMS service information that is interested in itself to inform the base station which MBMS service information is interested in.

For another example, an NR cell supports an SC-PTM transmission mechanism, a base station may transmit an MBMS service to UEs in different states in the cell, and the UE may feed back state Information (Channel Status Information) of a Channel in which the UE is located, for example, the state Information may be a signal Quality Indicator (Channel Quality Indicator) of a serving cell measured by the UE, so that the base station may count Channel state Information of the MBMS service received in the cell, so as to determine an appropriate modulation and coding strategy for transmitting the MBMS service, and improve spectral efficiency of transmission.

The number of terminals in the serving cell is uncertain, so that the network equipment is uncertain about the number of terminals to be fed back, and the network equipment cannot accurately and reasonably configure feedback resources; if too many feedback resources are configured, the resources are wasted; if the feedback resource configuration is too small, a resource conflict may arise. A two-stage feedback mechanism is introduced, and when the feedback is carried out in the first stage, the network equipment firstly configures a part of feedback resources for implementing the feedback of a part of terminals in the cell; and when the feedback is carried out in the second stage, the network equipment judges the number of the terminals needing to be fed back according to the feedback in the first stage, and then configures feedback resources fed back in the second stage for the terminals which do not implement the feedback but need the feedback to implement the feedback.

For example, for the aforementioned session2, the base station may configure that all UEs receiving the service need to perform feedback, or part of the UEs receiving the service need to perform feedback (for example, the UE in a connected state needs feedback, or the UE needs feedback only when the quality of the serving cell signal received by the UE is higher than a preset threshold); if the UE in the idle state or the inactive state needs to implement feedback, the base station does not know the number of UEs that need to be fed back when initially setting the feedback resources, and thus the base station cannot configure the feedback resources well. Therefore, the base station is configured with a set of two-stage feedback mechanism, and when the feedback is carried out in the first stage, the base station is firstly configured with a part of feedback resources for a part of UE in the cell to implement the feedback; and during the feedback of the second stage, the base station judges the number of the UE needing to be fed back according to the feedback of the first stage, and then configures feedback resources fed back by the second stage for the UE which does not implement the feedback but needs the feedback to implement the feedback.

For example, since the number of UEs in the cell can be estimated approximately by the coverage of the serving cell, or the number of UEs in the cell can be estimated approximately by the activity of the UEs in the cell, the base station can determine the allocation of the feedback resources fed back in the first stage according to the coverage of the serving cell and the activity of the UEs.

For example, the base station needs to receive the UE of Session2 for feedback, and the base station may configure the feedback resource fed back at the first stage through the system message or the SC-MCCH information, such as the time-frequency resource indicating the feedback resource of the UE; the base station may further indicate the number of UEs fed back at the first stage and determine the specific UEs fed back at the first stage through the system message or the SC-MCCH information, and the determined UEs may learn, through the system message, which multicast services the cell will broadcast and implement the feedback through the time-frequency resources configured by the base station.

For example, when the base station determines that the UE needs to perform feedback for a certain MBMS service or multiple MBMS services, but does not determine how many UEs need to perform feedback, the base station allocates a preliminary feedback resource to allow some UEs to perform feedback. Specifically, the base station can configure a parameter which is taken by a modulus, and the UE ID is used for taking the modulus so that part of the UE implements feedback; or the base station configures a scale factor, and the UE implements feedback through the scale factor control part.

For example, the base station may configure the parameter whose value is modulo 11, modulo the UE ID by 11, different UEs obtain different values between 0 and 10 according to their UE IDs MOD 11, and the base station may configure only the UE whose value is 1 to implement the first-stage feedback, so that only the UE of 1/11 implements the feedback basically.

For another example, the base station may configure the scaling factor, where the scaling factor is a value between 0 and 1, and assuming that the scaling factor configured by the base station is 0.1, the UE needing to feedback takes a random number between 0 and 1, and if the obtained random number is lower than the scaling factor, the UE needs to feedback in the first stage, so that only 10% of the UEs perform feedback in the first stage, and the base station may allocate less feedback resources in the first stage feedback in this way.

For example, if the base station needs the UE to feed back which MBMS services are interested, the time-frequency resource for the UE to feed back may be configured through the system message, such as on which timeslot and which physical resource blocks, to feed back for a certain MBMS service of interest.

For another example, if the base station needs the UE to perform feedback for the received MBMS data, such as feedback of an Acknowledgement (ACK) signal or a non-acknowledgement (NACK) signal, the base station may configure via the SC-MCCH information, the UE performs feedback at a certain time slot after receiving the MBMS data, and configures feedback resources, so that the UE transmits ACK or NACK on the feedback resources. In particular, if the base station needs to receive the UE feedback reception status ACK/NACK of the session2, the base station may configure the UE to perform feedback at a certain time slot after receiving the packet of the session2, for example, the packet of the UE receiving the session2 is located at the time slot n, the feedback is located at the time slot n + k, and k may be configured by the base station or adopt a default value.

When the terminal implements feedback, different terminals correspond to different feedback resources, and the feedback resources corresponding to the terminal may be determined according to a certain rule, for example, a mapping relationship may be established between an identifier of the terminal and/or an index of a beam serving the terminal and the resources for implementing feedback by the terminal. Different terminals determine the specific mapping rule of the self feedback resource, which is not limited herein.

For example, a group of UEs receives session2, where the group of UEs all have their own group identifiers, the base station configures the total feedback resource quantity fed back in the first stage, and different UEs determine their own feedback resource positions according to their own group identifiers, which is specifically as follows: in one scenario, UEs receiving session2 originally belong to a Group or Group (Group), each UE has its own in-Group identifier, and this Group may be set in advance by an operator; in another scenario, the UE does not have a specific group, the UE receiving the session2 in the current cell creates a temporary group, each UE has a UE identity, and the UE identity of each UE can be used as an intra-group identity of the temporary group.

For another example, an NR cell may have multiple beams, different UEs are served by different beams, and a UE may determine its feedback resource location according to an index (index) of the beam where the UE is located; or combining the index of the beam where the UE is positioned with the intra-group identification of the UE to determine the position of the feedback resource of the UE.

For example, in the first stage of feedback, the base station configures a part of feedback resources to enable a part of UEs to perform feedback, for example, modulo by a UE ID may be used to enable a part of UEs to perform feedback or control a part of UEs to perform feedback through a scaling factor; and then the base station judges the total feedback resource quantity needing to be configured or the feedback resource quantity needing to be configured and associated for each synchronous signal block according to the received feedback information fed back in the first stage, and then adjusts the total feedback resource quantity or the feedback resource quantity associated with each synchronous signal block so as to obtain the feedback resource fed back in the second stage.

For example, when the base station determines that the number of UEs to be fed back is small, it indicates that there are few UEs fed back in the second stage, and in order to avoid resource waste, the feedback resources cannot be configured too much, so that the number of feedback resources fed back in the second stage can be reduced; when the base station determines that the number of the UEs to be fed back is large, it indicates that there are many UEs fed back in the second stage, and in order to avoid resource conflict, the feedback resources cannot be configured too little, so that the number of the feedback resources fed back in the second stage can be increased.

Specifically, when the number of UEs served by different beams (beams) is very different, and therefore each beam corresponds to a specific Synchronization Signal Block (SSB), and each SSB is associated with a feedback resource, the mapping relationship between the feedback resource and the SSB can be adjusted, so that the feedback resource can be fully utilized.

For example, the feedback resources associated with the synchronization signal block SSB1 corresponding to beam 1 are less utilized, that is, there are fewer UEs feeding back information through beam 1; the feedback resources associated with the synchronization signal block SSB2 corresponding to beam 2 are utilized more, that is, more UEs feed back information through beam 2; thus, feedback resources associated on SSB1 may be scheduled for SSB2 association, e.g., feedback resources associated with SSB1 may be decreased and feedback resources associated with SSB2 may be increased; or the feedback resources associated with SSBs 1 and 2, respectively, may be modified to have SSBs 1 associate a set of feedback resources with SSBs 2 at the same time.

Specifically, the network device determines the required total number of feedback resources according to the received feedback information fed back at the first stage, and then adjusts the number of feedback resources, or adjusts the number of feedback resources and feedback time, or adjusts the mapping relationship between the uplink feedback resources and a Synchronization Signal Block (SSB) through SC-MCCH information or newly introduced DCI.

In order to notify the terminal of the feedback resource fed back in the second stage as soon as possible, mainly notifying other terminals to be fed back except for the terminal which has already implemented feedback in the first stage, the network device indicates the feedback resource configuration condition fed back in the second stage to the terminal through SC-MCCH information or newly introduced DCI, and after receiving the feedback resource configuration condition fed back in the second stage, the other terminals to be fed back can implement feedback in the second stage. By the method, the network equipment can reasonably configure the feedback resources, and resource waste is avoided.

For example, the first case: the base station may determine the number of UEs that need to be fed back in the serving cell from the received feedback information fed back in the first stage, for example, a scaling factor of 0.1 is set in the first stage, the base station receives the feedback of 50 UEs, the base station may approximately determine that about 500 UEs need to be fed back, 50 UEs have already been fed back in the first stage, and about 450 UEs need to be fed back in the second stage; therefore, the base station configures feedback resources for the second-stage feedback through the SC-MCCH information or the newly introduced DCI, for example, the base station may configure more than 450 feedback resources in the second-stage feedback to ensure that all UEs to be fed back can implement feedback.

The second case: if the feedback resources required for the second-stage feedback are more, the base station may set different feedback resources in multiple time periods, for example, 225 feedback resources may be configured for one time slot, another 225 feedback resources may be configured for another time slot, and a part of the UEs to be fed back perform feedback in the first time slot and another part perform feedback in another time slot.

Also for example, in NR, a serving cell may typically be covered by multiple beams, so UEs in the cell are served by different beams, e.g. a cell may be covered by 4 beams, or by 8 beams; because of the imbalance in UE distribution, the number of UEs served by different beams may be different, and therefore the number of UEs needing feedback under different beams is also different. In the first-stage feedback, the base station has no prior knowledge, and can equally allocate feedback resources according to the beam, and after the base station obtains part of the feedback information of the UE in the first-stage feedback, the base station can judge the distribution of the UE to be fed back under different beams, so the base station can adjust the number of the feedback resources under different beams, for example, in the first-stage feedback, more UEs feed back through the feedback resources corresponding to the beam 1, and the base station predicts that when in the second-stage feedback, more UEs also feed back under the coverage of the beam 1, so that more feedback resources can be configured to correspond to the beam 1.

The above example describes a scenario in which the base station needs to re-allocate more feedback resources in the second phase, and the same is applicable to a scenario in which the base station needs to re-allocate less feedback resources in the second phase.

For example, in the first stage of feedback, the base station configures 10 feedback resources under 8 beams covering the serving cell, that is, 8 × 10 — 80 feedback resources; assuming that the scaling factor is 0.5, it is expected that there are 160 UEs needing feedback, but the base station actually receives the feedback of only 20 UEs, so the base station can determine that there are about 20 UEs needing feedback in the second stage; the base station may adjust the number of feedback resources fed back at the second stage, for example, may adjust a mapping relationship between beams and feedback resources, for example, may map feedback resources corresponding to the UE to be fed back under 2 beams to the same resource pool, that is, 2 beams correspond to 1 resource pool, 5 feedback resources exist in 1 resource pool, 8 beams correspond to 4 resource pools, that is, 8 beams correspond to 20 feedback resources.

It can be seen that, in this example, the network device configures feedback resources fed back at the second stage to the terminals in the serving cell by sending the second SC-MCCH information or the downlink control information, and optionally selects the terminals fed back at the second stage from the terminals in the serving cell by sending the second SC-MCCH information or the downlink control information, and then the terminals fed back at the second stage send a piece of feedback information to the network device, so that the network device can reasonably configure the feedback resources fed back at the second stage according to the feedback condition fed back at the first stage, thereby avoiding configuring too many feedback resources, avoiding competition of multiple terminals on the same feedback resources fed back at the second stage, and facilitating reasonable resource configuration. The network device may set the terminal fed back in the second stage through the second SC-MCCH information or the downlink control information, or may not configure the terminal, where the terminal to be fed back is the remaining terminal excluding the terminal already fed back in the first stage.

For example, when the base station sets the feedback resources, the feedback resources are distributed according to time, so that the UEs needing to feedback perform feedback in an average distribution within a period of time, rather than feedback together, and one UE only feeds back once, and the feedback time is determined according to a certain algorithm within a period of time. For example, the base station configures a feedback resource of 100 slots (slots), and the UE performs modulo according to the UE identity, so that different UE feedback times are dispersed in the 100 slots.

Referring to fig. 3, fig. 3 is a resource allocation method according to an embodiment of the present application, where the method is applied to a network device, and the method includes, but is not limited to the following steps:

step 301, sending first configuration information, where the first configuration information is used to configure a first feedback resource;

step 302, receiving first feedback information transmitted from a first terminal through the first feedback resource, where the first feedback information is used for the first terminal to implement feedback on an MBMS service;

step 303, sending second configuration information, where the second configuration information is used to configure a second feedback resource, the second feedback resource is used for a second terminal to transmit second feedback information, and the second feedback information is used for the second terminal to implement feedback on the MBMS service.

The network device may send configuration information to the terminal in the serving cell, where the configuration information is used to configure a feedback resource for the terminal to implement feedback, and then receive feedback information transmitted by the terminal in the serving cell through the feedback resource. However, since the number of terminals in the serving cell is uncertain, the network device is uncertain about the number of terminals to be fed back, and therefore the network device cannot accurately and reasonably configure feedback resources; if too many feedback resources are configured, the resources are wasted; if the feedback resource configuration is too small, a resource conflict may arise. A two-stage feedback mechanism is introduced, and when the feedback is carried out in the first stage, the network equipment firstly configures a part of feedback resources for implementing the feedback of a part of terminals in the cell; and when the feedback of the second stage is carried out, the network equipment configures feedback resources fed back by the second stage for the terminal which does not implement the feedback but needs the feedback to implement the feedback.

The terminal fed back in the first stage can be selected from all terminals needing to be fed back in the serving cell by setting a scaling factor or a parameter which is taken as a modulo value.

The second feedback resource can be configured in advance as the first feedback resource; or the second feedback resource can also be determined according to the feedback condition fed back in the first stage; or as with the first feedback resource, a third feedback resource is preliminarily configured for the second-stage feedback, and then the third feedback resource is dynamically adjusted according to the feedback condition of the first-stage feedback, so as to obtain a second feedback resource.

For example, 100 UEs in the serving cell need feedback, but the base station does not know that 100 UEs need feedback, the base station first configures the first feedback resource for 20 UEs of the 100 UEs to perform feedback, and then configures the second feedback resource for the remaining 80 UEs to perform feedback.

As can be seen, in this example, since the network device does not know how many terminals in the cell need to perform feedback at first, it is not possible to accurately configure feedback resources for implementing feedback by the terminals, and if too many feedback resources are configured, the transmission resources are wasted; if the feedback resource allocation is too little, the resource conflict is serious; therefore, a set of two-stage feedback mechanism can be designed, the network equipment configures a part of feedback resources to enable a part of terminals to implement feedback, and after receiving the feedback of the part of terminals, the network equipment configures another part of feedback resources to enable another part of terminals to implement feedback; therefore, the network equipment can configure reasonable feedback resources for implementing feedback of the terminal aiming at the MBMS service.

For example, 100 UEs in the serving cell need feedback, but the base station does not know that 100 UEs need feedback, the base station first configures a first feedback resource for performing feedback on 20 UEs in the 100 UEs, and when receiving the first feedback information fed back by the 20 UEs, the base station can know that a plurality of UEs still need feedback in the serving cell or how many UEs including the 20 terminals in the serving cell need feedback, that is, the base station knows that 80 UEs still need feedback or knows that 100 UEs in the serving cell need feedback in total; then, the base station can accurately configure the second feedback resource with 80 resource positions for the remaining 80 UEs to implement feedback, so that the waste of resources can be reduced and resource conflict can be avoided.
