Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a method, apparatus and storage medium for transmitting service data of Multimedia Broadcast / Multicast Service (MBMS). Background Technology

[0002] Currently, MBMS technology in communication systems supports broadcast and multicast functions for video services.

[0003] Taking the mobile TV service as an example, when a user needs to watch mobile TV, the user equipment (UE) receives the corresponding video service data through the service resource allocation information indicated by the access network equipment, and presents it to the user on the user equipment.

[0004] However, for current MBMS service data transmission methods, 5G systems require beam sweeping for MBMS transmission. Beam sweeping reduces available radio resources, making it difficult for a narrow initial bandwidth part (BWP) to meet the resource requirements of MBMS services. Therefore, a wider BWP is needed for MBMS services. For user equipment receiving MBMS service data, how to perform bandwidth part (BWP) operations to ensure timely transmission of MBMS service data remains a challenge. No suitable and effective method has yet been provided in related technologies. Summary of the Invention

In some instances, methods, means, components, and circuits well known to those skilled in the art have not been described in detail in order to highlight the main points of this disclosure.

[0087] This disclosure provides a method for transmitting MBMS service data. During a pre-configured MBMS service period, if the user equipment's current first BWP is not a second BWP supporting MBMS service data, the user equipment switches the first BWP to the second BWP; listens to the PDCCH on the second BWP; and receives MBMS service data based on the scheduling information on the listened PDCCH. This allows the user equipment to automatically switch its current first BWP to the BWP required for the MBMS service data, avoiding the need for access network equipment scheduling control to switch BWPs in related technologies, thus ensuring timely transmission of MBMS service data.

[0088] Please refer to Figure 1This illustration shows a schematic diagram of the structure of a mobile communication system provided in an exemplary embodiment of this disclosure. The mobile communication system can be an LTE system, a 5G system (also known as a New Radio (NR) system), or a next-generation mobile communication technology system after 5G; this embodiment does not limit the specific implementation.

[0089] Optionally, the mobile communication system is suitable for different network architectures, including but not limited to relay network architecture, dual-link architecture, and vehicle-to-everything (V2X) architecture.

[0090] The mobile communication system includes: access network equipment 120 and user equipment 140.

[0091] Access network device 120 can be a base station (BS), also known as base station equipment, which is a device deployed in a Radio Access Network (RAN) to provide wireless communication functions. For example, in a 2G network, devices providing base station functions include base transceiver stations (BTS); in a 3G network, devices providing base station functions include NodeBs; in a 4G network, devices providing base station functions include evolved NodeBs (eNBs); in wireless local area networks (WLANs), devices providing base station functions are access points (APs); in 5G systems, devices providing base station functions are gNBs and further evolved NodeBs (ng-eNBs).

User equipment 140 can receive downlink data sent by access network equipment 120 through a wireless connection with access network equipment 120.

[0095] One point that needs to be clarified is that when Figure 1 When the mobile communication system shown adopts a 5G system or a next-generation mobile communication technology system of 5G, the above-mentioned network elements may have different names in the 5G system or the next-generation mobile communication technology system of 5G, but have the same or similar functions. This disclosure does not limit this.

[0096] Another point that needs to be explained is that, in Figure 1 The mobile communication system shown may include multiple access network devices 120 and / or multiple user equipment 140. Figure 1 The example shown is an access network device 120 and a user equipment 140, but the embodiments disclosed herein are not limited thereto.

[0097] The present disclosure provides a method for transmitting MBMS service data using several exemplary embodiments.

[0098] Please refer to Figure 2 This document illustrates a flowchart of an exemplary embodiment of the MBMS service data transmission method provided by this disclosure. This embodiment uses this method for... Figure 1 The following example uses a user device as an illustration. The method includes the following steps.

[0099] Step 201: During the pre-configured MBMS service period, if the user equipment's current first BWP is not a second BWP that supports MBMS service data, then the first BWP is switched to the second BWP.

[0100] The MBMS service period is pre-configured by the access network equipment. Also known as the MBMS-related PDCCH listening period, the MBMS service period is a pre-configured time segment used for listening to the PDCCH and transmitting MBMS service data.

[0101] The first BWP is the current BWP of the user equipment. Optionally, the first BWP can be a pre-configured default BWP or the initial BWP. The user equipment transmits service and signaling data other than MBMS service data on the current BWP.

[0102] The second BWP is a BWP pre-configured by the access network equipment to support MBMS service data.

[0103] Optionally, before the user equipment switches from the first BWP to the second BWP, it also includes: obtaining BWP configuration information, which includes the configuration information of the MBMS service period, the second BWP, and the PDCCH.

[0104] Indicatively, when the user equipment is in an idle or connected state, it obtains BWP configuration information from system messages or MBMS control messages. The BWP configuration information includes the configuration information of the MBMS service period, the second BWP, and the PDCCH.

[0105] Indicatively, the user equipment is in a connected state, sending signaling to indicate the MBMS service to be received; and receiving dedicated BWP configuration information for the MBMS service, which includes configuration information for the MBMS service period, the second BWP, and the PDCCH.

[0106] Optionally, the access network equipment is configured with a second BWP to support MBMS service data, and for MBMS services requiring feedback, a Physical Uplink Control Channel (PUCCH) is configured for transmitting feedback information. That is, the BWP configuration information also includes a PUCCH for transmitting feedback information.

[0107] In the Hybrid Auto Repeat Request (HARQ) mechanism, this feedback information is sent by the user equipment (UE) to the access network equipment after receiving MBMS service data from the access network equipment. The feedback information indicates whether the UE has correctly received the MBMS service data. The feedback information typically includes an acknowledgment (ACK) and a non-acknowledgment (NACK). ACK indicates that the UE has correctly received the MBMS service data, while NACK indicates that the UE has not correctly received the MBMS service data.

[0108] Optionally, at the start of the MBMS service period, if the user equipment's current first BWP is not a second BWP that supports MBMS service data, the user equipment will switch the first BWP to the second BWP.

[0109] Step 202: Listen to the PDCCH on the second BWP.

[0110] After the user equipment switches from the first BWP to the second BWP, the user equipment listens to the PDCCH on the second BWP.

[0111] Step 203: Receive MBMS service data based on the scheduling information monitored on the PDCCH.

[0112] The user equipment receives MBMS service data on the second BWP based on the scheduling information intercepted on the PDCCH.

[0113] Optionally, after receiving MBMS service data, the user equipment sends feedback information to the access network device, including ACK or NACK. That is, if the user equipment has correctly received the MBMS service data, it sends ACK to the access network device; if the user equipment has not correctly received the MBMS service data, it sends NACK to the access network device.

[0114] In summary, the embodiments of this disclosure, during a pre-configured MBMS service period, if the user equipment's current first BWP is not a second BWP that supports MBMS service data, the user equipment switches the first BWP to the second BWP; listens to the PDCCH on the second BWP; and receives MBMS service data according to the scheduling information on the listened PDCCH. This allows the user equipment to automatically switch its current first BWP to the BWP required for the MBMS service data to be received, avoiding the situation in related technologies where access network equipment scheduling control is required to switch BWPs, and ensuring the timely transmission of MBMS service data.

[0115] Among related technologies, the 3GPP NR MBMS technology standard has been listed as a Release 17 (R17) target. MBMS services require swept beam transmission, meaning that the actual MBMS resources in the time domain can only be 1 / N, where N is the number of swept beams. Considering the large-scale development of MBMS services, it is foreseeable that the BWP providing MBMS will be relatively wide in the frequency domain.

[0116] If a user equipment in the connected state has no data transmission (excluding MBMS service data) during the initial active period of the DRX corresponding to the inactive BWP timer, it is predicted that there will be no large amount of data transmission in the following period. The user equipment will switch to the default BWP and listen to the PDCCH on the default BWP with a relatively narrow bandwidth. Data transmission and reception are performed according to the scheduling information on the PDCCH. Generally, the frequency range of the default BWP is relatively narrow, so power consumption can be saved.

[0117] For a user equipment in a connected state that receives MBMS service data, how to perform BWP operation to both ensure the transmission of MBMS service data and achieve the effect of saving power consumption? This disclosure provides a possible implementation method, which will be described and illustrated through the following exemplary embodiments.

[0118] Please refer to Figure 3 This illustrates a flowchart of a method for transmitting MBMS service data provided in another exemplary embodiment of this disclosure. This embodiment uses this method for... Figure 1 The following example uses a user device as an illustration. The method includes the following steps.

[0119] Step 301: Obtain BWP configuration information, which includes the configuration information of MBMS service period, second BWP and PDCCH.

[0120] Optionally, the user equipment in the connected state sends signaling to indicate the MBMS service to be received; the user equipment receives dedicated BWP configuration information configured for the MBMS service, the dedicated BWP configuration information including the configuration information of the MBMS service period, the second BWP and the PDCCH.

[0121] Optionally, the user equipment in the connected state obtains BWP configuration information from system messages or MBMS control messages. The BWP configuration information includes the configuration information of MBMS service period, second BWP and PDCCH.

[0122] That is, the user equipment in the connected state sends signaling to the access network equipment. This signaling is used to indicate the MBMS service that the user equipment needs to receive, such as the MBMS service that the user equipment is interested in.

[0123] If the user equipment receives dedicated BWP configuration information for MBMS services from the access network device, it uses the MBMS service period, second BWP, and PDCCH configuration from this dedicated BWP configuration information during the connected state. If the user equipment does not receive dedicated BWP configuration information for MBMS services from the access network device, it uses the MBMS service period, second BWP, and PDCCH configuration from the BWP configuration information during the connected state. The BWP configuration information is obtained by the user equipment from system messages or MBMS control messages.

[0124] Optionally, the user equipment may send Radio Resource Control (RRC) signaling or MBMS signaling to the access network equipment to indicate the MBMS service to be received.

[0125] Step 302: During the pre-configured MBMS service period, if the user equipment's current first BWP is not a second BWP that supports MBMS service data, then the first BWP is switched to the second BWP.

[0126] During the pre-configured MBMS service period, if the user equipment's current first BWP is not the second BWP that supports MBMS service data, the user equipment in the connected state will switch the first BWP to the second BWP.

[0127] Optionally, at the start of the MBMS service period, if the user equipment is in a discontinuous reception (DRX) inactive state and the user equipment's current first BWP is not a second BWP that supports MBMS service data, then the first BWP will be switched to the second BWP.

[0128] The first BWP is the current BWP of the user equipment, and the second BWP is a pre-configured BWP used to support MBMS service data.

[0129] Optionally, the first BWP can be either the pre-configured default BWP or the initial BWP.

[0130] It should be noted that the process of obtaining the MBMS service period and the second BWP can be referred to the relevant details in the above embodiments, and will not be repeated here.

[0131] Step 303: Listen to the PDCCH on the second BWP.

[0132] After the user equipment switches from the first BWP to the second BWP, the user equipment listens to the PDCCH on the second BWP.

[0133] Step 304: Receive MBMS service data based on the scheduling information monitored on the PDCCH.

[0134] The user equipment receives MBMS service data on the second BWP based on the scheduling information intercepted on the PDCCH.

[0135] Step 305: At the end of the MBMS service period, if no data scheduling other than MBMS service data is received during the MBMS service period, the second BWP is switched back to the first BWP.

[0136] If no data scheduling other than MBMS service data is received during the MBMS service period, the user equipment will automatically switch back to the BWP before PDCCH monitoring after the MBMS service period ends, that is, the second BWP will be switched back to the first BWP.

[0137] Step 306: If data scheduling other than MBMS service data is received during the MBMS service period, start the DRX inactive timer and / or the BWP inactive timer.

[0138] If data scheduling other than MBMS service data is received during the MBMS service period, the user equipment will perform DRX management and / or BWP management, that is, start the DRX inactivation timer and / or BWP inactivation timer.

[0139] Optionally, if the DRX inactivity timer expires, the user equipment enters the DRX inactivity state. That is, while the inactivity timer is active, the user equipment is in the active state; if the DRX inactivity timer expires, the user equipment enters the DRX inactivity state.

[0140] Optionally, if the BWP inactive timer times out, the user equipment will automatically switch back to the BWP before PDCCH listening, that is, switch the second BWP back to the first BWP.

[0141] In an illustrative example, such as Figure 4 As shown, the user equipment (UE) receives the MBMS control channel according to the system message configuration to learn about various MBMS services provided by the cell, such as MBMS service1-20. After the UE enters the connected state due to a certain service A, it is configured with initial BWP0 and BWP1, where BWP0 is configured as the default BWP, and BWP1 is configured with the MBMS-related control resource set (CORESET) / search space (SS). During the service A process, the UE notifies the base station of its interest in MBMS service12 high-definition video via RRC signaling or MBMS signaling. MBMS service12 requires the UE to provide HARQ feedback. The access network equipment configures the UE with BWP2 for receiving the corresponding MBMS service12 service data and configures the corresponding PUCCH for feedback, keeping the UE in the connected state for MBMS feedback.

[0142] Service A ends at time t1. Before time t2 (i.e., t1 + bwp - InactivityTimer), the user equipment is on BWP1 during the MBMS service period. The user equipment automatically switches to BWP2 to listen to the PDCCH. Based on the scheduling information on the PDCCH, it receives MBMS service data and performs PUCCH feedback. If no data scheduling other than MBMS service data is received during the MBMS service period, the user equipment automatically switches back to BWP1 at the end of the MBMS service period. If data scheduling other than MBMS service data is received during the MBMS service period, the DRX inactivity timer and / or the BWP inactivity timer are started. If the DRX inactivity timer times out, the user equipment enters the DRX inactivity state. If the BWP inactivity timer times out, the user equipment automatically switches back to BWP1.

[0143] After time t2 (i.e., t1 + bwp - InactivityTimer), during the MBMS service period on the default BWP (BWP0), the user equipment automatically switches to BWP2 to listen to the PDCCH. Based on the scheduling information on the listened PDCCH, it receives MBMS service data and performs PUCCH feedback. At the end of the MBMS service period, the user equipment automatically switches back to BWP0.

[0144] In one possible implementation, the user equipment is in a connected state. That is, for the user equipment in the connected state, the method further includes: if the MBMS service period and the DRX initial activity period after the start time of the MBMS service period meet the first preset condition, then listen to the PDCCH on the second BWP during the DRX initial activity period; receive the first transmission data according to the scheduling information on the listened PDCCH, the first transmission data including MBMS service data.

[0145] The first preset condition includes an overlap between the initial DRX activity period and the MBMS service period, or the interval between the time windows corresponding to the initial DRX activity period and the MBMS service period is less than a first preset threshold. The initial DRX activity period is the period following the start time of the MBMS service period.

[0146] It should be noted that the DRX activity period includes the drx-onDurationTimer activity period and the drx-InactivityTimer activity period. In this embodiment, the initial DRX activity period is the drx-onDurationTimer activity period.

[0147] The first preset threshold is either pre-configured or custom-set. This disclosure does not limit this aspect.

[0148] The overlap between the DRX initial activity period and the MBMS business period means that the time windows corresponding to the DRX initial activity period and the MBMS business period overlap.

[0149] Optionally, the first transmitted data includes MBMS service data and other data besides MBMS service data.

[0150] Optionally, if no data scheduling other than MBMS service data is received during the MBMS service period, the user equipment will switch back to the first BWP at the end of the MBMS service period. Related details can be found in the descriptions in the above embodiments, and will not be repeated here.

[0151] Optionally, if data scheduling other than MBMS service data is received during the MBMS service period, the user equipment starts a DRX inactivation timer and / or a BWP inactivation timer. If the DRX inactivation timer expires, the user equipment enters the DRX inactivation state. If the BWP inactivation timer expires, the user equipment automatically switches back to the BWP before PDCCH listening, that is, switches the second BWP back to the first BWP. Related details can be found in the descriptions in the above embodiments, and will not be repeated here.

[0152] In summary, the MBMS service data transmission method provided in this disclosure, for a user equipment in a connected state, in one aspect, during a pre-configured MBMS service period, if the user equipment's current first BWP is not a second BWP that supports MBMS service data, then the first BWP is switched to the second BWP, and the second BWP listens to the PDCCH, receiving MBMS service data according to the scheduling information on the listened PDCCH; thus, without the need for access network equipment scheduling control, the user equipment can automatically switch its current first BWP to a second BWP that supports the MBMS service data to be received. On the other hand, if the second BWP, which supports MBMS service data, is continuously used, although the service is not affected, receiving data on the second BWP, which has a wider frequency range, consumes more power. Therefore, this embodiment of the present disclosure also switches the second BWP back to the first BWP at the end of the MBMS service period if no data scheduling other than MBMS service data is received during the MBMS service period; or, if data scheduling other than MBMS service data is received during the MBMS service period, the DRX inactive timer and / or the BWP inactive timer are started. If the BWP inactive timer times out, the user equipment automatically switches back to the BWP before PDCCH listening, that is, switches the second BWP back to the first BWP. This ensures normal reception of MBMS service data while also taking into account the power consumption of the user equipment.

[0153] This embodiment of the disclosure also allows the user equipment to listen to the PDCCH on the second BWP during the DRX initial activity period if the DRX initial activity period after the start time of the MBMS service period overlaps with or is adjacent to the MBMS service period (i.e., the interval between the time windows corresponding to the DRX initial activity period and the MBMS service period is less than a first preset threshold). This avoids the situation where hardware switching of the BWP requires a certain amount of time, enabling the user equipment to listen to the PDCCH on the second BWP in a timely manner to receive MBMS service data, further ensuring the timely transmission of MBMS service data.

[0154] In related technologies, a user equipment in idle state listens to the PDCCH on the initial BWP to receive paging messages or system messages, or receives a random access response upon access. If a user equipment in idle state needs to receive MBMS services, it may be configured with a BWP with a larger bandwidth. This MBMS BWP listens to the PDCCH to receive paging messages or system messages, or receives a random access response upon access, or receives MBMS services.

[0155] For a user equipment (UE) in an idle state that receives MBMS service data, how to perform BWP operation to both ensure MBMS service data transmission and save power consumption? This disclosure provides a possible implementation method. In this implementation, the UE is in an idle state, and step 301, i.e., the UE obtaining BWP configuration information, may include: the UE in the idle state obtaining BWP configuration information from system messages or MBMS control messages. The BWP configuration information includes configuration information for the MBMS service period, the second BWP, and the PDCCH.

[0156] Steps 305 to 306 above can be replaced with the following steps, such as... Figure 5 As shown:

[0157] Step 501: At the end of the MBMS service period, switch the second BWP back to the first BWP.

[0158] At the end of the MBMS service period, user equipment in idle state will switch back to the first BWP from the second BWP.

[0159] When the user equipment is in an idle state, the first BWP is also called the initial BWP.

[0160] Optionally, if the PDCCH listening period for transmitting paging messages or system messages and the MBMS service period meet the second preset condition, then the PDCCH is listened to on the second BWP; and second transmission data is received according to the scheduling information on the listened PDCCH, the second transmission data including at least one of paging messages, system messages and MBMS service data.

[0161] The second preset condition includes the overlap between the PDCCH monitoring period and the MBMS service period, or the interval between the time windows corresponding to the PDCCH monitoring period and the MBMS service period is less than the second preset threshold.

[0162] The second preset threshold is either pre-configured or custom-set. This disclosure does not limit this aspect.

[0163] The overlap between the PDCCH monitoring period and the MBMS service period means that the time windows corresponding to the PDCCH monitoring period and the MBMS service period overlap.

[0164] Optionally, the interval between the time windows corresponding to the PDCCH listening period and the MBMS service period being less than the second preset threshold includes: the MBMS service period being earlier than the PDCCH listening period, and the interval between the time windows corresponding to the PDCCH listening period and the MBMS service period being less than the second preset threshold.

[0165] Among them, the MBMS service period is also called the MBMS-related PDCCH listening period, and the PDCCH listening period used to transmit paging messages or system messages is also called the paging-related PDCCH listening period.

[0166] Optionally, the user equipment initiates a random access request on the second BWP; listens to the PDCCH on the second BWP during the random access period; and receives third transmission data based on the scheduling information on the listened PDCCH. The third transmission data includes at least one of paging messages, random access responses, and MBMS service data.

[0167] Since the duration of the random access process is uncertain, after the user equipment initiates a random access request on the second BWP, it directly listens for the PDCCH on the second BWP during the random access period.

[0168] In an illustrative example, a user equipment (UE) receives MBMS control channel information based on system message configuration to learn about various MBMS services offered by the cell, such as MBMS services 1-20. If the UE is interested in MBMS service 10 (live sports video), it is on the initial BWP before the MBMS service period begins. During the MBMS service period, the UE automatically switches to BWP1, which supports the MBMS service data, listens to the PDCCH on BWP1, and receives MBMS service data based on the scheduling information on the listened PDCCH. After the MBMS service period ends, the UE automatically switches back to the initial BWP.

[0169] During the MBMS service period, which overlaps with or is adjacent to the subsequent paging-related PDCCH listening period, the user equipment listens for MBMS-related PDCCH on BWP1 to receive MBMS service data. Subsequently, the user equipment receives and listens for paging-related PDCCH on BWP1. After the MBMS service period ends, the user equipment automatically switches back to the initial BWP.

[0170] At a certain moment, the user equipment initiates random access on BWP1. During the random access period, it listens on PDCCH on BWP1 to receive scheduled data, which includes at least one of paging messages, random access responses, and MBMS service data.

[0171] In summary, the MBMS service data transmission method provided in this embodiment allows for the following for a user equipment in an idle state: during a pre-configured MBMS service period, if the user equipment's current first BWP is not a second BWP that supports MBMS service data, the first BWP is switched to the second BWP to listen to the PDCCH and receive MBMS service data, without requiring access network equipment scheduling control. Furthermore, since receiving data on the second BWP, which has a wider frequency range, is more power-consuming, the user equipment switches back to the first BWP at the end of the MBMS service period, ensuring normal reception of MBMS service data while also considering the user equipment's power consumption.

[0172] This embodiment of the disclosure further involves listening to the PDCCH on the second BWP if the PDCCH listening period used for transmitting paging messages or system messages overlaps with the MBMS service period, or if the interval between the time windows corresponding to the PDCCH listening period and the MBMS service period is less than a second preset threshold; and receiving the second transmission data according to the scheduling information on the listened PDCCH; thus avoiding the situation where switching BWPs requires a certain amount of time, and enabling the user equipment to directly listen to the PDCCH on the second BWP to receive MBMS service data when the paging-related PDCCH listening period overlaps or is adjacent to the MBMS service period, further ensuring the timely transmission of MBMS service data.
