Description

Service receiving method, terminal and network side equipment

Technical Field

The application belongs to the technical field of wireless communication, and particularly relates to a service receiving method, a terminal and network side equipment.

Background

Multimedia broadcast multicast service (Multimedia Broadcast and Multicast Service, MBMS or MBS) may be generally transmitted in two ways:

mode 1: by transmitting over a physical multicast channel (Physical Multicast Channel, PMCH) in (MBMS single frequency network Multimedia Broadcast multicast service Single Frequency Network, MBSFN) subframes. Wherein the control information is transmitted via system information (e.g., SIB 13) and a broadcast control channel (Multicast Control Channel, MCCH), and the data is transmitted via a broadcast traffic channel (Multicast Traffic Channel, MTCH).

Mode 2: and (2) transmitting the physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) scheduled by the physical downlink control channel (Physical Downlink Control Channel, PDCCH). Wherein, the control information of the MBS service is transmitted through the system information (such as SIB 20) and the single-cell broadcast control channel (Single Cell Multicast Control Channel, SC-MCCH), and the data of the MBS service is transmitted through the single-cell broadcast service channel (Single Cell Multicast Traffic Channel, SC-MTCH). The SC-MCCH may be transmitted through PDSCH scheduled by a radio network temporary identifier (Single Cell Radio Network Temporary Identity, SC-RNTI) PDCCH, and the SC-MTCH may be transmitted through PDSCH scheduled by a Group-RNTI (G-RNTI) PDCCH.

In the related art, a network side may configure a plurality of carriers for a terminal, where the carriers may include 1 Special Cell, spCell or PCell, which may also be referred to as a primary Cell, and 1 or more Secondary cells (SCell), so as to save power of the terminal, and in some cases, may control a certain Secondary Cell of the terminal to enter a deactivated state or a dormant state through control signaling.

In addition, a cell of a terminal may be simultaneously configured with a plurality of different frequency ranges, and each frequency range may be referred to as a Bandwidth Part (BWP), and in general, the terminal may only have 1 active BWP in 1 cell at most, and thus, the active BWP of a certain cell of the terminal may be converted into a deactivated state or a dormant state in some cases.

After a certain frequency band (e.g., a certain secondary cell or BWP of a certain cell) in which the terminal is currently operating is deactivated or in a sleep state, the terminal does not monitor the data channel on the frequency band. Since the multicast service may transmit a configuration to the terminal through broadcasting information, when the terminal receives the MBS service in a certain frequency band (e.g., SCell cell or BWP), the network side may not immediately know that the terminal receives the MBS service in the frequency band, but deactivates the frequency band of the terminal, thereby causing the terminal to fail to receive the MBS service in the frequency band.

Since it can be seen that if MBS service is transmitted on a certain SCell or a certain BWP of a certain cell of a UE, the UE cannot receive MBS service transmitted on the SCell or the BWP if the SCell or the BWP transitions from an active state to an inactive state. In order to solve the problem, the embodiment of the application provides a service receiving scheme.

The technical scheme provided by the embodiment of the application is described in detail through specific embodiments and application scenes thereof by combining the accompanying drawings.

Fig. 2 shows a schematic flow diagram of a service receiving method in an embodiment of the application, and the method 200 may be performed by a terminal. In other words, the method may be performed by software or hardware installed on the terminal. As shown in fig. 2, the method may include the following steps.

S210, when the target frequency band is deactivated or in a sleep state, if the terminal receives the target MBS service in the target frequency band, the terminal keeps receiving the target MBS service in the target frequency band.

In the embodiment of the application, when the target frequency band of the MBS service received by the UE is deactivated or in a sleep state, the MBS service is still received on the deactivated target frequency band through network side configuration or protocol convention. According to the network side configuration or protocol convention, the UE performs S210.

In the embodiment of the application, when the target frequency band of the terminal is deactivated or in a sleep state, if the terminal receives the target MBS service on the target frequency band, the target MBS service is kept to be received on the target frequency band, so that the problem that the target MBS service on the target frequency band of the terminal is interrupted due to the fact that the target frequency band of the terminal is deactivated or in the sleep state can be solved, and the receiving of the MBS service can be ensured while the electric quantity of the terminal is saved.

In the present application, the terminal maintains the reception of the MBS service in the inactive frequency band, and for other services, the terminal may refer to the provision in the related art to determine to perform the operation on the inactive frequency band. For example, the terminal does not receive unicast traffic in the inactive frequency band. The embodiment of the present application is not limited in particular.

In one possible implementation, the terminal maintaining to receive the target MBS service on the target frequency band may include: and maintaining the scheduling control information and the data transmission corresponding to the target MBS service.

In the embodiment of the application, the target MBS service can be the MBS service interested by the terminal.

For example, on the target frequency band of deactivation of the UE there is a PDCCH configuration for the unicast scheduled UE (e.g., C-RNTI PDCCH), a PDCCH configuration for the multicast scheduled UE (e.g., control resource set (CORESET) and/or search space (Searching spacing) for MBS service), and an identification MBS RNTI-1 for the multicast service schedule. Wherein different MBS services may have different identities for multicast service scheduling. For example, for MBS service-1, the multicast service schedule is identified as MBS RNTI-1. For MBS service-2, the multicast service schedule is identified as MBS RNTI-2). Then when the UE is interested in the MBS RNTI-1 of the target frequency band (the MBS RNTI-1 corresponds to the target MBS service), and when the target frequency band is deactivated, the UE stops receiving C-RNTI PDCCH while maintaining receiving the MBS RNTI-1PDCCH.

In order to enable the network side to know the receiving condition of the UE on the target MBS service, the UE may send feedback information for the target MBS service to the network side, and when the target frequency band is deactivated or in a sleep state, since the UE keeps receiving the target MBS service on the target frequency band, in a possible implementation manner, transmission of the feedback information of the target MBS service may also be kept.

In one possible implementation, the target frequency band may be a first target secondary cell (SCell) of the terminal.

In one possible implementation manner, if the target feedback information is sent on the first target secondary cell under the condition that the target frequency band can be the first target secondary cell of the terminal, after the first target secondary cell is deactivated or in a sleep state, the target feedback information is continuously sent on the first target secondary cell, where the target feedback information is feedback information received for the target MBS service. That is, in this possible implementation, if feedback information of a target MBS service is transmitted on a first target secondary cell before the first target secondary cell is deactivated or put into a sleep state, the target feedback information is continuously transmitted on the first target secondary cell after the first target secondary cell is deactivated or put into a sleep state.

For example, before the SCell-1 is deactivated, HARQ feedback information received by PDSCH for MBS service on SCell-1 is transmitted on PUCCH of deactivated SCell-1, and the UE continues to transmit the feedback information on PUCCH of deactivated SCell-1.

In another possible implementation manner, if the target feedback information is sent on a second target secondary cell of the terminal under the condition that the target frequency band can be the first target secondary cell of the terminal, after the first target secondary cell is deactivated or in a sleep state, continuing to send the target feedback information on the second target secondary cell under the condition that the second target secondary cell is activated, wherein the target feedback information is feedback information received for the target MBS service.

For example, before the deactivation of SCell-1, PDSCH reception of MBS is performed on SCell-1, and HARQ feedback information received by PDSCH of MBS for the SCell-1 is transmitted on PUCCH of SCell-2, then after the deactivation of SCell-1, if SCell-2 is active, UE continues to transmit the feedback information on PUCCH of SCell-2.

In another possible implementation, the target frequency band is a first target BWP of a first cell of the terminal.

In the above possible implementation manner, when the terminal feeds back the feedback information for the target MBS service, if the uplink feedback channel is configured on the first target BWP and the uplink feedback channel can be used for feedback received by the MBS service, after the first target BWP is deactivated or in a sleep state, the terminal continues to send the target feedback information on the uplink feedback channel, where the target feedback information is the feedback information received for the target MBS service.

For example, BWP-1 configures a PUCCH for feeding back HARQ feedback information received by a PDSCH of an MBS of the BWP-1, and when the BWP-1 is deactivated (or in a sleep state), the UE continues to transmit the feedback information on the PUCCH of the BWP-1.

Or in another possible implementation manner, if an uplink feedback channel is configured on a second target BWP of the first cell and the uplink feedback channel configured on the second target BWP can be used for feedback of MBS service reception, after the first target BWP is deactivated or in a sleep state, target feedback information is sent on the uplink feedback channel configured on the second target BWP, where the second target BWP is in an active state, and the target feedback information is feedback information received for the target MBS service.

For example, the BWP-1 of the UE receiving MBS is deactivated (or in a sleep state), BWP-2 of the same cell as BWP-1 configures HARQ feedback information that the PUCCH may use to feed back PDSCH reception of the MBS, BWP-2 is in an active state, and the UE transmits feedback information for MBS reception on BWP-1 on BWP-2.

Or in another possible implementation manner, if the target feedback information is sent on the second cell of the terminal, after the first target bandwidth part is deactivated or in a sleep state, if the second cell is in an active state, the target feedback information is continuously sent on the second cell, where the target feedback information is feedback information received for the target MBS service.

For example, the PDSCH of MBS receives as BWP-1 at SCell-1, and the HARQ feedback information received by the PDSCH of BWP-1 of SCell-1 is transmitted on the PUCCH of SCell-2, then when BWP-1 of SCell-1 is deactivated or in sleep state, the UE continues to transmit the feedback information at SCell-2 while SCell-2 is active.

In one possible implementation manner, if the target frequency band is the first target BWP of the first cell of the terminal, the terminal maintaining to receive the target MBS service on the target frequency band may include: and alternately working on a third target BWP and the first target BWP in a time division mode, wherein the third target BWP is the BWP currently activated by the terminal. Through the possible implementation manner, the transmission of other services can be continued while the transmission of the target MBS service is maintained.

In the above possible implementations, the working time interval of the UE on the third target BWP and the first target BWP is determined by the network side configuration or the terminal.

For example, the network configuration slot-1/2/3 operates at the currently active BWP-1 (i.e., the third target BWP), and at slot-4/5/6 at BWP-2 (i.e., the first target BWP) where there is MBS traffic the UE is interested in receiving.

Alternatively, when the UE does not have data scheduling or transceiving (e.g., DRX inactive time interval) at the currently active BWP (i.e., the third target BWP), the UE transitions to BWP (i.e., the first target BWP) operation of receiving its MBS service of interest.

If the UE is configured by the network side in the working time interval on the third target BWP and the first target BWP, optionally, before the target MBS service is received on the target frequency band, the method further comprises: and sending notification information to a network side, wherein the notification information indicates a desired working time interval of the terminal on the third target BWP and the first target BWP. With this possible implementation manner, the network side may perform configuration with reference to the notification information sent by the UE when configuring the third target BWP and the working time interval on the first target BWP, so as to meet the requirement of the UE.

For example, the UE may report its propensity as: slot-1/2/3 works in the currently active BWP-1 and slot-4/5/6 works in BWP-2.

Alternatively, in another possible implementation manner, the UE keeps receiving the target MBS service on the target frequency band, including: and switching to work on the first target BWP. Through the possible implementation manner, the UE is directly switched to the first target BWP to work, so that the complexity of the UE implementation can be reduced while the transmission of various services of the UE is ensured.

In the foregoing possible implementation manner, in order to enable the network side to acquire that the UE is switched to operate on the first target BWP, optionally, before switching to operate on the first target BWP, the method further includes: transmitting indication information to a network side, wherein the indication information indicates at least one of the following:

(1) The terminal changes the working BWP;

(2) The terminal will change the working BWP;

(3) And the identification of the first target BWP.

Through the above optional implementation manner, the network side may learn that the UE has changed the working BWP, the BWP to be changed, and the target BWP to be changed.

In each of the foregoing possible implementations, optionally, before the target MBS service is received on the target frequency band, the method further includes: and indicating a frequency band identifier to a network side, wherein the frequency band identifier is used for indicating a frequency band for receiving MBS service which is interested in being received by the terminal, and the frequency band identifier comprises the identifier of the first target frequency band.

For example, the SCell-1 and the SCell-2 configured by the UE have the MBS service-1 sent, and the secondary cell in which the UE is interested in receiving the MBS service-1 is SCell-1, so that the UE may report the identity of SCell-1 to the network side.

For another example, the UE may have both BWP-1 and BWP-2 configured in a certain cell to transmit the MBS service-1, and the BWP of the UE interested in receiving the MBS service-1 is BWP-1, and the UE may report the identity of the BWP-1 to the network side.

Through the above alternative implementation manner, when the UE has the same MBS service transmission on multiple target frequency bands at the same time, the UE may designate that the MBS service is transmitted on one of the target frequency bands.

In each of the foregoing possible implementations, optionally, the method further includes: and reporting the power configuration information of the target frequency band which is deactivated or in a sleep state. For example, reporting the PH and P of deactivated SCell-1 in PHR _CMAX,f,c . Through the optional implementation manner, the power configuration information of the inactive frequency band can be reported to the network side, so that the network side can control the power of the uplink information on the inactive frequency band.

The following describes the technical solution provided by the embodiment of the present application by taking the receiving of the MBS service on the inactive secondary cell and the inactive BWP as an example.

Fig. 3 shows another flow chart of a service receiving method according to an embodiment of the present application, and the method 300 may be performed by a terminal. In other words, the method may be performed by software or hardware installed on the terminal. As shown in fig. 3, the method may include the following steps.

And S310, receiving a control signaling for deactivating the SCell, and switching the SCell to a deactivated state.

S312, before the SCell is deactivated, MBS service is received in the SCell, and MBS service is still received in the deactivated SCell according to network side configuration or protocol convention.

Optionally, the MBS service is an MBS service of interest to the UE.

In one possible implementation, the UE may keep receiving scheduling control information and data information corresponding to MBS services of its interest.

For example, the deactivated SCell-1 of the UE has a PDCCH configuration for the unicast scheduled UE (e.g., C-RNTI PDCCH), a PDCCH configuration for the multicast scheduled UE (e.g., core et and/or Searching spacing of the MBS), and an identification MBS RNTI-1 for the multicast service schedule, where different MBS services may have different identifications of the multicast service schedule (e.g., for MBS service-1, the identification of the multicast service schedule is MBS RNTI-1. For MBS service-2, the identification of the multicast service schedule is MBS RNTI-2). Then if SCell-1 is deactivated when the UE is interested in MBS RNTI-1 of SCell-1, the UE stops receiving C-RNTI PDCCH while remaining receiving MBS RNTI-1PDCCH.

And S314, according to the configuration of the network side or protocol convention, the UE feeds back the receiving of the MBS service.

Wherein, the sending of the feedback information for the MBS service includes but is not limited to any one of the following:

(1) If the transmission of the feedback information received by the MBS is on the SCell before the SCell is deactivated, the feedback information continues to be transmitted on the SCell. For example, the HARQ feedback information received by PDSCH of MBS is transmitted on PUCCH of deactivated SCell-1, and the UE continues to transmit the feedback information.

Of course, without being limited thereto, the network side may also configure or the protocol may agree that in this case the transmission of the feedback information on the PUCCH of the deactivated SCell-1 is stopped.

(2) If the feedback information received by the MBS is sent in other cells, if the sending cell of the feedback information is activated, the sending feedback information received by the MBS of the deactivated SCell is continuously sent in other cells.

For example, the PDSCH of MBS is received as being in SCell-1, and the HARQ feedback information received by the PDSCH of MBS of SCell-1 is transmitted on the PUCCH of SCell-2, then the UE continues to transmit the feedback information in SCell-2 when SCell-2 is active.

Of course, without being limited thereto, the network side may also configure or the protocol may agree that in this case the transmission of the feedback information on the deactivated SCell-2 is stopped.

In one possible implementation, the UE may also indicate to the network side the identity of the cell it is interested in receiving MBS. For example, both SCell-1 and SCell-2 configured by the UE have MBS service-1 transmissions, and the UE may receive the MBS service-1 on SCell-1.

Optionally according to network side configuration or protocol conventionsThe UE also reports the power configuration information of the deactivated SCell (e.g., the PH and P of deactivated SCell-1 in PHR _CMAX,f,c ) Therefore, the network side can perform power control on uplink data sent by the deactivated SCell.

Fig. 4 shows a further flowchart of a service receiving method according to an embodiment of the present application, and the method 400 may be performed by a terminal. In other words, the method may be performed by software or hardware installed on the terminal. As shown in fig. 4, the method may include the following steps.

S410, the received control signaling indicates that the BWP is deactivated or in a sleep state, and the BWP is switched to the deactivated or sleep state.

S412, determining that the MBS service of interest to the terminal is received on the BWP before the BWP is deactivated or in the sleep state, the MBS service is still received on the BWP that is deactivated or in the sleep state according to the network side configuration or protocol convention.

I.e. according to the network side configuration or protocol convention, when the UE receives BWP deactivation of MBS or is in sleep state, the MBS service is still received on the deactivated or sleep state BWP. For example, the UE keeps receiving scheduling control information and data information corresponding to MBS services of interest to the UE.

Wherein, the UE keeps receiving the scheduling control information and the data information corresponding to the MBS service of interest to the UE may include any one of the following:

method 1: the UE works alternately on the currently activated BWP and the BWP with the MBS service interested in receiving by the UE in a time division mode;

method 2: the UE switches to operate on BWP of MBS service it is interested in receiving.

For method 1, the working time interval of each BWP in the "time division manner" is configured by the network side or determined autonomously by the UE.

For example, the network configuration slot-1/2/3 operates at the currently active BWP-1 and at slot-4/5/6 at BWP-2 where there is MBS traffic the UE is interested in receiving.

For another example, when the UE does not have data scheduling or transceiving in the current BWP (e.g., DRX inactive time interval), the UE transitions to BWP operation of MBS service it is interested in receiving.

Wherein, for method 1, optionally, the UE may notify the network side of its tendency in the working time interval of each BWP.

For example, the UE reports its propensity: slot-1/2/3 works in the currently active BWP-1 and slot-4/5/6 works in BWP-2.

Wherein, for method 2, optionally, the UE may send indication information to the network side. Wherein the content of the indication information comprises at least one of the following:

(1) Informing the network side that it has changed the working BWP;

(2) BWP to be changed;

(3) The identity of the target BWP changed (i.e., the above-described deactivated or sleep-state BWP).

S414, according to the configuration of the network side or the agreement, the UE feeds back the MBS reception.

Wherein, the sending of the feedback information for the MBS reception may include any one of the following:

(1) If an uplink feedback channel is configured on the deactivated or sleep BWP and the channel can be used for transmission of feedback information received by the MBS, the UE continues or stops transmitting feedback information on the deactivated or sleep BWP.

For example, BWP-1 configures a PUCCH for feeding back HARQ feedback information received by a PDSCH of an MBS of the BWP-1, and when the BWP-1 is deactivated or in a sleep state, the UE continues to transmit the feedback information in the BWP-1.

(2) An uplink feedback channel is configured on the active BWP of the same cell as the deactivated or sleep BWP, and the channel may be used for transmission of feedback information received by the MBS, and the UE feeds back the feedback information received by the MBS of the deactivated or sleep BWP at the active BWP.

For example, if the UE receives BWP-1 of the MBS and is deactivated or in a sleep state, BWP-2 configures HARQ feedback information that PUCCH may be used to feedback PDSCH reception of the MBS, and BWP-2 is in an active state, the UE transmits feedback information of MBS reception on BWP-1 in BWP-2.

(3) If the feedback information received by the MBS is sent in other cells, if the sending cell of the feedback information is activated, the sending feedback information of the MBS receiving the BWP which is deactivated or in a sleep state is continuously sent.

For example, the PDSCH of MBS receives as BWP-1 at SCell-1, and the HARQ feedback information received by PDSCH of BWP-1 of SCell-1 is transmitted on PUCCH of SCell-2, the UE continues to transmit the feedback information when SCell-2 is active.

Of course, not limited thereto, in this case, the UE may also stop transmitting the feedback information on the PUCCH of SCell-2, which may be specifically determined according to the network side configuration or protocol convention.

Alternatively, the UE may indicate to the network side the identity of BWP that it is interested in receiving MBS (e.g., the UE configured BWP-1/2 has MBS service-1 sent and the UE receives the MBS service-1 on BWP-1).

Optionally, according to the configuration or protocol convention of the network side, the UE reports the power configuration information of the deactivated (or sleep state) BWP, so as to facilitate the power control of the network side. For example, reporting the PH and P of BWP-1 in PHR in a deactivated or sleep state _CMAX,f,c 。
