[0091] S201, receiving configuration information of semi-persistent scheduling of MBS sent by a network device.

[0092] Multicast Broadcast Service (MBS) refers to a point-to-multipoint service in which one data source sends data to multiple users, realizing network resource sharing, including mobile core network and access network resource sharing, especially air interface resource. Not only can it realize pure text low-speed string message type multicast and broadcast, but also can realize high-speed multimedia service broadcast and multicast.

[0093] Semi-persistent scheduling refers to that after a terminal device applies for semi-persistent resources once, the corresponding semi-persistent resources are periodically allocated to the terminal device within a period of time.

[0094] In the present application, in order to enable the terminal device to receive MBS data through semi-persistent scheduling resources according to different service characteristics, the terminal device can receive configuration information of semi-persistent scheduling of MBS sent by a network device.

[0095] Optionally, the configuration information of semi-persistent scheduling can include: an identifier of MBS, first configuration information of semi-persistent resources, and second configuration information of indication signaling for activating or deactivating semi-persistent resources.

[0096] The identifier of the MBS can include a temporary mobile group identity (TMGI), an MBS session ID, and an MBS QoS flow ID.

[0097] S202, activating or deactivating the semi-persistent resource of the MBS according to the configuration information.

[0098] According to the configuration information of the semi-persistent scheduling of the MBS sent by the network device obtained above, the semi-persistent resource corresponding to the MBS is obtained, and further, the indication signaling of the network device sending the MBS can be determined according to the configuration information, and the terminal device can execute the process of activating the semi-persistent resource or the process of deactivating the semi-persistent resource according to the indication signaling.

[0099] After the physical downlink shared channel (PDSCH) resource corresponding to the semi-persistent resource is activated, the terminal device can receive the corresponding MBS through the PDSCH. Optionally, the semi-persistent resource can be one or more resources.

[0100] The present application provides a semi-persistent scheduling method of multicast broadcast service (MBS), and the terminal device receives the configuration information of the semi-persistent scheduling of the MBS sent by the network device; and activates or deactivates the semi-persistent resource of the MBS according to the configuration information. According to different service characteristics, the terminal device can receive MBS data through the semi-persistent scheduling resource, so that the terminal device can reduce the loss of dynamic scheduling signaling when receiving the MBS, and can reduce the reception delay of service data.

[0101] Reference Figure 3 , Figure 3 is a flow diagram of a semi-persistent scheduling method of multicast broadcast service (MBS) provided by an embodiment of the present application. The method is applied to a terminal device, and based on the above-mentioned embodiment, as shown in Figure 3 , the method comprises the following steps.

[0105] As described in the above embodiments, the configuration information of the semi-persistent scheduling can include: an identifier of the MBS, first configuration information of the semi-persistent resource, and second configuration information of the indication signaling for activating or deactivating the semi-persistent resource.

[0106] In some implementations, according to the configuration information, the second configuration information of the indication signaling can be determined, and the indication signaling can be monitored according to the second configuration information. The indication signaling is used to instruct the terminal device to execute the process of activating the semi-persistent resource or the process of deactivating the semi-persistent resource. The second configuration information can include an identifier of the indication signaling and a discontinuous reception configuration for monitoring the indication signaling.

[0107] Optionally, according to the second configuration information, the identifier of the indication signaling is determined, and the indication signaling is monitored according to the identifier of the indication signaling. For example, the identifier of the indication signaling can be a group-configured scheduling-radio network temporary identity (G-CS-RNTI) identifier of a physical downlink control channel (PDCCH) used to activate the corresponding semi-persistent scheduling (SPS) resource in the MBS.

[0108] Optionally, after the discontinuous reception configuration of the indication signaling is determined according to the second configuration information, the discontinuous reception cycle is determined according to the discontinuous reception configuration, the time domain reception map on the reception duration in the discontinuous reception cycle is determined, the monitoring time slot corresponding to the indication signaling is determined according to the time domain reception map, and the indication signaling is monitored in the monitoring time slot. As shown in the following table, the discontinuous reception configuration includes the discontinuous reception cycle and the reception duration in the discontinuous reception cycle, such as the discontinuous reception cycle being 10s and the reception duration in the discontinuous reception cycle being 5s. The discontinuous reception configuration also includes the time domain reception map on the reception duration, wherein the time domain reception map includes the monitoring time slot corresponding to the indication signaling and the occupied time slot corresponding to the semi-persistent resource.

Optionally, the time domain reception map can also be represented by a bit map, wherein the first bit represents the first time slot, and the value "1" of the time slot indicates that the time slot needs to be monitored, and the value "0" of the time slot indicates that the time slot does not need to be monitored.​

[0109] S303, if the indication signaling indicates that the terminal device is activated, activating the semi-persistent resource of the MBS.

[0110] If the indication signaling indicates that the terminal device activates the semi-persistent resource, for example, the indication signaling for activating the semi-persistent resource is an activation instruction (Activate CMD), the terminal device activates the semi-persistent resource.

[0111] S304, if the indication signaling indicates that the terminal device is deactivated, deactivating the semi-persistent resource of the MBS.

[0112] Similar to the indication signaling indicating that the terminal device activates the semi-persistent resource, if the indication signaling indicates that the terminal device deactivates the semi-persistent resource, for example, the indication signaling for deactivating the semi-persistent resource is a deactivation instruction (Deactivate CMD), the terminal device deactivates the semi-persistent resource.

The candidate semi-persistent resource set indicated by the activation indication signaling is taken as the semi-persistent resource set, and the physical downlink shared channel (PDSCH) resource corresponding to the semi-persistent resource set is activated, and then the corresponding MBS is received through the PDSCH. The semi-persistent resource set is one or more of the one or more candidate semi-persistent resource sets.

[0123] As an implementable way, the identification information of the semi-persistent resource set indicated by the indication signaling is determined, and each semi-persistent resource set is activated according to the identification information of the semi-persistent resource set. The identification information can be one or more.

[0124] Optionally, the indication signaling can display the identification information of the semi-persistent resource set, for example, Figure 4 The SPS resource set-1 and SPS resource set-2 shown are the identification information of the two candidate semi-persistent resource sets, and when the activation indication signaling instructs to activate the SPS resource set-1, the SPS resource set-1 is taken as the semi-persistent resource set. The activation indication signaling can instruct to activate only the SPS resource set-1, or only the SPS resource set-2, or simultaneously activate the SPS resource set-1 and the SPS resource set-2.

[0125] Optionally, the indication signaling can implicitly indicate the identification information of the semi-persistent resource set. For example, the identification information of the semi-persistent resource set can be the list item number in the semi-persistent resource set list. For example, there are two semi-persistent resource sets in the semi-persistent resource set list, which are SPS resource set-1 and SPS resource set-2. The list is arranged in order, the number of the first semi-persistent resource set SPS resource set-1 is "1", and the number of the second semi-persistent resource set SPS resource set-2 is "2". That is, if the activation indication signaling indicates activation "1", the terminal device activates the first semi-persistent resource set SPS resource set-1; if the activation indication signaling indicates activation "2", the terminal device activates the second semi-persistent resource set SPS resource set-2.

[0126] As another implementable manner, the group identification information of the semi-persistent resource set group indicated by the indication signaling is determined, and the semi-persistent resource set group includes at least one semi-persistent resource set; and each semi-persistent resource set included in the semi-persistent resource set group is activated according to the group identification information.

[0127] Optionally, the indication signaling can explicitly indicate the identification information of the semi-persistent resource set group. For example, the identification information of the semi-persistent resource set group can be the list item number in the semi-persistent resource set group list. Figure 4 For example, the SPS resource set-1 and the SPS resource set-2 shown in the figure can be combined as a semi-persistent resource set group, the group identification information of the semi-persistent resource set group can be SPS resource set group 1, and when the indication signaling indicates activation of the SPS resource set group 1, the SPS resource set-1 and the SPS resource set-2 included in the SPS resource set group 1 are activated.

[0128] Optionally, the indication signaling can adopt implicit indication of identification information of the semi-persistent resource set group. For example, the group identification information of the semi-persistent resource set group can be the list item number in the semi-persistent resource set group list. For example, there are four semi-persistent resource sets in the semi-persistent resource set list, which are SPS resource set-1, SPS resource set-2, SPS resource set-3 and SPS resource set-4. Among them, SPS resource set-1 and SPS resource set-2 can be combined as a semi-persistent resource set group, and the group identification information of this semi-persistent resource set group can be recorded as SPS resource set group 1. SPS resource set-3 and SPS resource set-4 can be combined as a semi-persistent resource set group, and the group identification information of this semi-persistent resource set group can be recorded as SPS resource set group 2. Then arrange the list in order, the number of the first semi-persistent resource set group SPS resource set group 1 is "1", and the number of the second semi-persistent resource set SPS resource set group 2 is "2". That is, if the activation indication signaling indicates activation "1", the terminal device activates the first semi-persistent resource set SPS resource set group 1; if the activation indication signaling indicates activation "2", the terminal device activates the second semi-persistent resource set SPS resource set group 2.

[0129] S505, determining that the indication signaling indicates deactivation of the terminal device, and the deactivation indication signaling indicates the semi-persistent resource set.

[0130] In the embodiment of the application, the candidate semi-persistent resource configured by the network device for the MBS is determined according to the first configuration information corresponding to the semi-persistent resource in the configuration information. The first configuration information includes a candidate semi-persistent resource set, wherein the candidate semi-persistent resource set can be one or more. The candidate semi-persistent resource set indicated by the deactivation indication signaling is taken as a semi-persistent resource set, the physical downlink shared channel (PDSCH) resource corresponding to the semi-persistent resource set is deactivated, and then the corresponding MBS is received through the PDSCH. Wherein, the semi-persistent resource set is one or more of the one or more candidate semi-persistent resource sets.

[0131] As a realizable manner, the identification information of the semi-persistent resource set indicated by the indication signaling is determined, and each semi-persistent resource set is deactivated according to the identification information of the semi-persistent resource set, wherein the identification information can be one or more.

[0132] Optionally, the indication signaling can display the identification information of the semi-persistent resource set, for example, Figure 4 The SPS resource set-1 and SPS resource set-2 shown are identification information of two candidate semi-persistent resource sets, when the deactivation indication signaling indicates deactivation of the SPS resource set-1, the SPS resource set-1 is taken as a semi-persistent resource set. Wherein the deactivation indication signaling can indicate deactivation of only the SPS resource set-1, can also indicate deactivation of only the SPS resource set-2, and can also indicate deactivation of the SPS resource set-1 and the SPS resource set-2 at the same time.

[0133] Optionally, the indication signaling can imply the identification information of the semi-persistent resource set, for example, the identification information of the semi-persistent resource set can be the list item number in the semi-persistent resource set list. For example, there are two semi-persistent resource sets in the semi-persistent resource set list, which are SPS resource set-1 and SPS resource set-2, then the list is arranged in order, the first semi-persistent resource set SPS resource set-1 is numbered as "1", and the second semi-persistent resource set SPS resource set-2 is numbered as "2". That is, if the deactivation indication signaling indicates deactivation of "1", the terminal device deactivates the first semi-persistent resource set SPS resource set-1; if the deactivation indication signaling indicates deactivation of "2", the terminal device deactivates the second semi-persistent resource set SPS resource set-2.

[0134] As another realizable manner, the group identification information of the semi-persistent resource set group indicated by the indication signaling is determined, and each semi-persistent resource set included in the semi-persistent resource set group is deactivated according to the group identification information.

[0135] Optionally, the indication signaling can display the identification information of the semi-persistent resource set group, for example, the semi-persistent resource set group can be Figure 4The illustrated SPS resource set-1 and SPS resource set-2 can be combined as one semi-persistent resource set group, and the group identification information of the semi-persistent resource set group can be recorded as SPS resource set group 1. When the indication signaling indicates to deactivate SPS resource set group 1, SPS resource set-1 and SPS resource set-2 contained in SPS resource set group 1 are deactivated.

[0136] Optionally, the indication signaling can implicitly indicate the identification information of the semi-persistent resource set group. For example, the group identification information of the semi-persistent resource set group can be the list item number in the semi-persistent resource set group list. For example, there are four semi-persistent resource sets in the semi-persistent resource set list, which are SPS resource set-1, SPS resource set-2, SPS resource set-3, and SPS resource set-4. Among them, SPS resource set-1 and SPS resource set-2 can be combined as one semi-persistent resource set group, and the group identification information of the semi-persistent resource set group can be recorded as SPS resource set group 1; SPS resource set-3 and SPS resource set-4 can be combined as one semi-persistent resource set group, and the group identification information of the semi-persistent resource set group can be recorded as SPS resource set group 2. Then arrange the list in order, the number of the first semi-persistent resource set group SPS resource set group 1 is “1”, and the number of the second semi-persistent resource set SPS resource set group 2 is “2”. That is, if the deactivation indication signaling indicates to deactivate “1”, the terminal device deactivates the first semi-persistent resource set SPS resource set group 1; if the deactivation indication signaling indicates to deactivate “2”, the terminal device deactivates the second semi-persistent resource set SPS resource set group 2.
