Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and particularly to a data transmission method, an apparatus, and a computer-readable storage medium. Background Art

[0002] In order to enable user equipment (UE) for different types of services to perform paging monitoring on carriers with different paging configurations, or for the UE to select a carrier with a specific paging configuration for paging monitoring according to its own status and environment, such as the coverage level it is in, the magnitude of the reference signal received power (RSRP), etc. One possible implementation is to divide the carriers of a cell into multiple carrier sets (also called subsets), where different carrier sets correspond to different coverage levels or different services. The UE determines on which paging carrier to receive paging messages in the corresponding carrier set according to the corresponding coverage level or service type.

[0003] If it is determined in the future to introduce a carrier selection mechanism based on the coverage level, the existing determination mechanism for preconfigured uplink resource (PUR) transmission configuration needs to be redesigned. Otherwise, when the coverage level of the UE changes due to mobility, data transmission with the network will no longer be possible. Summary of the Invention

[0038] Compared with the prior art, the technical solution of the embodiment of the present invention has the following beneficial effects:

[0039] For the UE side, an embodiment of the present invention provides a data transmission method, including: if it is determined that the coverage level changes, sending change indication information to indicate that the coverage level of a user equipment changes to a target coverage level; receiving response information, where the response information is used to indicate whether the target PUR transmission configuration associated with the target coverage level is activated, or the response information is used to indicate updated values of at least one parameter in an initial PUR transmission configuration; continuing data transmission using the activated target PUR transmission configuration or the updated initial PUR transmission configuration according to the response information.

[0040] Compared with the existing technical solution that only configures a set of PUR transmission configurations for the current serving cell without considering the coverage level for the UE to transmit data, the present implementation can implement the configurations related to PUR transmission based on the coverage level to ensure that the UE can maintain effective data transmission with the network when the coverage level changes. Specifically, different coverage levels correspond to different PUR transmission configurations. Further, when the UE determines that the coverage level has changed, it requests to switch to using the target PUR transmission configuration associated with the target coverage level for data transmission by reporting the change in the coverage level this time. Further, according to the indication of the response information, the UE can continue to use the target PUR transmission configuration for data transmission in a timely manner when the target PUR transmission configuration is activated by the network, so as to maintain an effective data connection with the network at the target coverage level. Further, according to the indication of the response information, the UE can update the initial PUR transmission configuration so as to use the data transmission parameter configuration corresponding to the target coverage level for data transmission.

[0041] For the network side, an embodiment of the present invention further provides a data transmission method, including: receiving change indication information, where the change indication information is used to indicate that the coverage level of the user equipment has changed to a target coverage level; at least judging according to the network load whether to activate the target PUR transmission configuration associated with the target coverage level, or whether to update the value of at least one parameter in the initial PUR transmission configuration; generating and sending a response information according to the judgment result, where the response information is used to indicate whether the target PUR transmission configuration associated with the target coverage level is activated, or the response information is used to indicate the updated value of at least one parameter in the initial PUR transmission configuration; receiving data using the activated target PUR transmission configuration or using the updated initial PUR transmission configuration according to the response information.

[0042] Compared with the existing technical solution that does not consider the coverage level and only configures a set of PUR transmission configurations for the UE in the current serving cell for data transmission, the present implementation can achieve PUR transmission-related configurations based on the coverage level to ensure effective data transmission with the UE even when the UE's coverage level changes. Specifically, different coverage levels correspond to different PUR transmission configurations. Further, when it is determined according to the received change indication information that the UE's coverage level has changed, activate the target PUR transmission configuration for the UE so that the UE can maintain an effective data connection with the network using the corresponding target PUR transmission configuration at the target coverage level. Further, when it is determined that the UE's coverage level has changed, update at least one parameter in the initial PUR transmission configuration for the UE so that the UE can perform data transmission using the data transmission parameter configuration corresponding to the target coverage level. Further, measure whether to activate the target coverage transmission configuration or select the specific update value of the parameter to be updated according to the network load to balance the UE's requirements and the network's capabilities and provide a better communication experience for users.

[0047] As mentioned in the background art, if a carrier selection mechanism based on the coverage level is introduced in the future, then the existing PUR transmission configuration also needs to adapt to the carrier selection based on the coverage level.

[0048] Specifically, according to the current protocol regulations, the network will only configure a set of PUR transmission configurations for the UE in the current serving cell through Radio Resource Control (RRC) dedicated signaling. The PUR transmission configuration includes an uplink carrier index, a downlink carrier index, a PUR resource period, the number of repetitions of the Physical Uplink Shared Channel (PUSCH), and the configuration related to the downlink reception window, etc.

[0049] From the current discussion, it is very likely that in the future, carrier selection based on Coverage Enhancement (CE, also known as coverage range extension) will be introduced. The implementation method is that different carrier sets correspond to different coverage levels (CE Level).

[0050] Considering PUR transmission. There is also a collision problem between PUR transmission and paging. In the future, if different carrier sets correspond to different coverage levels, it will also affect the carrier configuration of PUR. The carrier configuration of PUR includes the PUR transmission carrier and the PUR Search Space (SS) monitoring carrier. That is to say, the carrier of PUR also needs to change with the change of the coverage level. Otherwise, according to the current configuration, the fact that the PUR carrier does not distinguish the coverage level will exacerbate the collision situation between PUR transmission and paging.

[0051] To solve the above technical problems, an embodiment of the present invention provides a data transmission method, including: if it is determined that the coverage level changes, sending change indication information to indicate that the coverage level of the user equipment changes to the target coverage level; receiving response information, where the response information is used to indicate whether the target PUR transmission configuration associated with the target coverage level is activated, or the response information is used to indicate the updated value of at least one parameter in the initial PUR transmission configuration; according to the response information, continuing data transmission using the activated target PUR transmission configuration or the updated initial PUR transmission configuration.

[0052] This implementation can realize the configuration related to PUR transmission based on the coverage level to ensure that the UE can maintain effective data transmission with the network when the coverage level changes. Specifically, different coverage levels correspond to different PUR transmission configurations. Further, when the UE determines that the coverage level changes, it requests to switch to using the target PUR transmission configuration associated with the target coverage level for data transmission by reporting the change of the current coverage level. Further, according to the indication of the response information, the UE can timely use the target PUR transmission configuration to continue data transmission when the network activates the target PUR transmission configuration, so as to maintain an effective data connection with the network at the target coverage level. Further, according to the indication of the response information, the UE can update the initial PUR transmission configuration so as to use the data transmission parameter configuration corresponding to the target coverage level for data transmission.

[0053] "PUR" as described in this implementation refers to the Preconfigure Uplink resource (abbreviated as PUR). Specifically, in order to enable the UE to directly transmit small data packets in the idle state, the existing NB-IOT or Enhanced Machine Type Communication (abbreviated as eMTC) mechanism is that the network configures a dedicated periodic PUR and the corresponding downlink search space window (PUR Search space window, abbreviated as PUR SS Window) for the UE through RRC dedicated signaling. Among them, the uplink carrier configured with PUR will be uniquely associated with a downlink carrier. The existing protocol stipulates that the network will only configure one uplink carrier for the UE to send PUR and one downlink carrier for receiving feedback information through RRC dedicated signaling. The UE can send uplink data through PUR, and then receive an acknowledgement (ACK) (such as indicating an acknowledgement of downlink control information), a fallback indication, or a retransmission scheduling message in the downlink search space window configured for the corresponding downlink carrier. Among them, the fallback indication (such as the fallback downlink control information) is used to instruct the UE to fallback to the Random Access Channel (abbreviated as RACH) or early data transmission (abbreviated as EDT, also known as early data transmission) to perform data transmission. The network can control the effectiveness of PUR resources through the fallback indication. That is, when the uplink resources are tight, the network can instruct the UE to fallback to use the RACH or / and EDT method for data transmission. The UE can directly send uplink data on PUR, thus avoiding the process of the UE initiating random access to enter the connected state.

[0054] The "NB-IoT multi-carrier" described in this implementation refers to the multi-carrier of Narrow Band Internet of Things (NB-IoT for short). Specifically, since the bandwidth of a single-frequency point cell in NB-IoT is only 180 kilohertz (kHz), after deducting the overhead of Narrowband Primary Synchronization Signal (NPSS for short), Narrowband Secondary Synchronization Signal (NSSS for short) and System Information Block (SIB), the remaining capacity of the service channel is very small. To support a large number of terminals, multiple frequency points are needed to increase the network capacity. In addition to the anchor carrier that includes NPSS, NSSS and Narrowband Physical Broadcast Channel (NPBCH), a cell may also include several non-anchor carriers that do not include NPSS, NSSS and NPBCH. Generally speaking, a cell includes one anchor carrier and several non-anchor carriers, the spectral bandwidth of each carrier is 180 kHz, and the maximum spectral span of all carriers in the cell does not exceed 20 megahertz (MHz).

[0055] The "anchor carrier" means that there is one and only one downlink carrier in a multi-carrier cell that supports simultaneous transmission of NPSS, NSSS, NPBCH, Narrowband Physical Downlink Control Channel (NPDCCH for short) and Narrowband Physical Downlink Shared Channel (NPDSCH for short), and this downlink carrier is called the anchor carrier. The UE needs to monitor NPSS, NSSS, NPBCH, NPDCCH and NPDSCH information on the anchor carrier.

[0056] The "non-anchor carrier" means that there may be several downlink carriers in a multi-carrier cell that only carry NPDCCH and NPDSCH, but do not carry NPSS, NSSS and NPBCH channels, and are called non-anchor carriers. The UE can perform data transmission on the non-anchor carrier. In addition, before the UE enters the connected state, the network will specify a carrier for subsequent downlink data transmission through the fourth message (Msg4) of the random access process. The UE can perform paging monitoring on the non-anchor carrier in the idle state.

[0057] To make the above objects, features, and beneficial effects of the present invention more obvious and understandable, the following provides a detailed description of specific embodiments of the present invention with reference to the accompanying drawings.

[0058] Figure 1 is a flowchart of a data transmission method according to a first embodiment of the present invention.

[0059] This implementation can be applied to a terrestrial network scenario.

[0060] This implementation can be executed on the user equipment side, such as by a UE on the user equipment side. By executing this implementation, when a UE in the idle state undergoes a change in coverage level, it can use the PUR transmission configuration corresponding to the changed coverage level (i.e., the target PUR transmission configuration) to continue effective data transmission with the network. Among them, the change in the coverage level may be caused by the mobility of the UE.

[0061] In a specific implementation, the data transmission method provided in the following steps S101 to S103 can be executed by a chip with data transmission functions in the user equipment or by a baseband chip in the user equipment.

[0062] Specifically, referring to Figure 1 , the data transmission method described in this embodiment may include the following steps:

[0063] Step S101, if it is determined that the coverage level has changed, send change indication information to indicate that the coverage level of the user equipment has changed to the target coverage level;

[0064] Step S102, receive response information, where the response information is used to indicate whether the target PUR transmission configuration associated with the target coverage level is activated, or the response information is used to indicate the updated values of at least one parameter in the initial PUR transmission configuration;

[0065] Step S103, according to the response information, continue data transmission using the activated target PUR transmission configuration or the updated initial PUR transmission configuration.

[0066] More specifically, the coverage level refers to the coverage level where the user equipment is located. It can be determined whether a change in the coverage level has occurred based on the measurement results of the signal quality. For example, a user equipment in the idle state can regularly measure the RSRP or the reference signal received quality (Reference Signal Received Quality, abbreviated as RSRQ), and when it is found that the measured RSRP or RSRQ is lower than a preset threshold, it is determined that a change in the coverage level has occurred (or is about to occur), and the target coverage level to which it will switch.

[0067] In a specific implementation, different coverage levels correspond to different PUR transmission configurations. The PUR transmission configuration includes parameters such as uplink carrier index, downlink carrier index, PUSCH repetition times, and timing advance values.

[0068] Specifically, a corresponding PUR transmission configuration is configured for each coverage level. For example, the target PUR transmission configuration is a PUR transmission configuration independent of the initial PUR transmission configuration. The fact that the target PUR transmission configuration is independent of the initial PUR transmission configuration means that the specific values of parameters such as uplink carrier index, downlink carrier index, PUSCH repetition times, and timing advance values are specifically set according to the PUR transmission configuration to which they belong.

[0069] The different coverage levels can be all the coverage levels corresponding to all the carriers of the UE's current serving cell. Specifically, a cell includes multiple carriers, each coverage level corresponds to a part of the carriers, and the sum of the carriers corresponding to all the coverage levels is all the carriers of the cell. Therefore, a cell corresponds to multiple coverage levels.

[0070] Furthermore, the initial PUR transmission configuration is associated with an initial coverage level, and the initial coverage level is determined when the user equipment is in the Connected state. That is, the coverage level of the user equipment in the connected state is determined as the initial coverage level. By configuring the initial PUR transmission configuration for the user equipment when it is in the connected state, the UE can use the initial PUR transmission configuration to directly perform data transmission with the network after entering the idle state without having to enter the random access process.

[0071] During the activation period of the initial PUR transmission configuration, the user equipment that enters the idle state can use the initial PUR transmission configuration for data transmission. During this period, if it is found that the coverage level has changed, step S101 can be executed to indicate the target coverage level to the network side.

[0072] Correspondingly, before the step S101, the data transmission method described in this embodiment may further include the steps of: receiving configuration information, where the configuration information includes multiple sets of PUR transmission configurations and an initial activation indication, and different PUR transmission configurations are associated with different coverage levels; determining the PUR transmission configuration pointed to by the initial activation indication as the initial PUR transmission configuration.

[0073] Furthermore, the action of receiving the configuration information can be executed during the period when the UE is in the connected state.

[0074] Furthermore, the configuration information can be carried by RRC dedicated signaling.

[0075] For example, before the UE enters the idle state, the network can configure multiple sets of PUR transmission configurations through RRC dedicated signaling. Each set of PUR configurations corresponds to a coverage level, and each set of PUR configurations includes parameters such as uplink carrier index, downlink carrier index, PUSCH repetition times, and timing advance values. At the same time, the network will activate one set of PUR configurations through RRC dedicated signaling according to the coverage level where the UE is currently located, so that the UE can use the activated PUR configuration (i.e., the PUR transmission configuration pointed to by the initial activation indication) for data transmission after entering the idle state. For other unactivated PUR configurations pre-configured through RRC dedicated signaling, the UE cannot use them temporarily.

[0076] For example, the RRC dedicated signaling can include an RRC release signaling.

[0077] In a specific implementation, in the step S101, the UE has entered the idle state and uses the initial PUR transmission configuration for data transmission according to the configuration information. During this period, due to the mobility of the UE, the coverage level where the UE is located will change.

[0078] Correspondingly, the step S101 may include the steps of: sending the change indication information at the PUR transmission opportunity of the initial PUR transmission configuration.

[0079] For example, when the UE determines that a coverage level change has occurred according to the measurement results, it can use the initial PUR transmission configuration to report the coverage level change indication. So that the network can timely learn about the coverage level change of the UE in the idle state.

[0080] In a specific implementation, the change indication information may include indication information of the target coverage level. That is, the UE reports the identifier corresponding to the target coverage level to the network, and the network searches for the target PUR transmission configuration corresponding to the target coverage level reported by the UE according to the pre-configured association relationship between the coverage level and the PUR transmission configuration.

[0081] Alternatively, the change indication information may include indication information of the target PUR transmission configuration. That is, the UE directly reports the identifier corresponding to the target PUR transmission configuration associated with the target coverage level to the network, eliminating the network search step.

[0082] In a specific implementation, the step S102 may include the steps of: receiving the response information using the downlink search space window corresponding to the PUR transmission opportunity of the initial PUR transmission configuration. Since it is not yet possible to determine whether the network has activated the target PUR transmission configuration at this time, the UE still uses the initial PUR transmission configuration to receive the response information.

[0083] Specifically, the response information may include an indication of an acknowledgment of downlink control information (ACK Downlink Control Information, abbreviated as ACK DCI). Moreover, indication information is set in the indication of the acknowledgment of downlink control information to indicate whether the target PUR transmission configuration is activated. Among them, the indication information may be a 1-bit indication bit.

[0084] For example, if the indication of the acknowledgment of downlink control information sent by the network is received, it indicates that the indication of the coverage level change reported by the UE is successful. Further, if the indication of the acknowledgment of downlink control information indicates that the target PUR transmission configuration corresponding to the target coverage level is activated, the UE may use the target PUR transmission configuration to transmit data.

[0085] In a specific implementation, whether the target PUR transmission configuration is activated may be determined according to the specific value of the indication bit.

[0086] For example, a value of 0 for this 1-bit in the indication of the acknowledgment of downlink control information indicates non-activation, and a value of 1 indicates activation. In practical applications, it may also be set that a value of 0 indicates activation and a value of 1 indicates non-activation.

[0087] In a specific implementation, whether the target PUR transmission configuration is activated may be determined according to whether the indication bit in the response information received this time has flipped (also known as inverted) compared with the indication bit in the response information received last time.

[0088] For example, if the value of this 1-bit in the indication of the acknowledgment of downlink control information received last time is 0, and the value of this 1-bit in the indication of the acknowledgment of downlink control information received this time is 1, it indicates that a flip has occurred, that is, the target PUR transmission configuration is activated; if the value of this 1-bit in the indication of the acknowledgment of downlink control information received this time is still 0, it indicates that no flip has occurred, that is, the target PUR transmission configuration is not activated.

[0089] In a specific implementation, if the response information indicates non-activation of the target PUR transmission configuration, it means that the UE cannot use the target PUR configuration to transmit data. Correspondingly, the UE may still use the initial PUR transmission configuration to transmit data subsequently. For example, the response information may be carried by fallback downlink control information.

[0090] In a specific implementation, the response information may include a release indication for instructing the UE to release the initial PUR transmission configuration. Correspondingly, the UE has no activated PUR transmission configuration and may enter a random access process subsequently to establish a data connection with the network. For example, the response information may be carried by fallback downlink control information.

[0091] In a specific implementation, the response information can be carried by high-layer signaling. Correspondingly, the response information can include an indication cell, and the user equipment determines whether the target PUR transmission configuration is activated according to the information represented by the indication cell.

[0092] Thus, the network configures the PUR transmission configuration for the UE on each coverage level through RRC dedicated signaling, and only the currently corresponding PUR transmission configuration can be activated and used at the current coverage level. When the coverage level changes and the UE reports the target coverage level, the network activates the PUR transmission configuration corresponding to the target coverage level (i.e., the target PUR transmission configuration) according to the UE's report.

[0093] In a variant, the UE can be configured with only one set of PUR transmission configurations (i.e., the initial PUR transmission configuration configured by the network side in the connected state), and at least one parameter in this set of PUR transmission configurations can correspond to different specific values at different coverage levels.

[0094] That is to say, the change in the coverage level only affects the specific values of some parameters in the initial PUR transmission configuration.

[0095] Correspondingly, before step S101, the data transmission method described in this embodiment may further include the step of: receiving configuration information, where the configuration information includes the initial PUR transmission configuration and also includes a candidate list of at least one parameter in the initial PUR transmission configuration, and different candidates in the candidate list are associated with different coverage levels.

[0096] Furthermore, the configuration information can be carried by RRC dedicated signaling.

[0097] Alternatively, at least the candidate list of the at least one parameter can be carried by system broadcast information.

[0098] Furthermore, for each parameter of the at least one parameter, the candidate list of the parameter can include multiple candidate sets, different candidate sets are associated with different coverage levels, and the updated value of the parameter in the initial PUR transmission configuration indicated by the response information is selected from the candidate set associated with the target coverage level in the candidate list.

[0099] Furthermore, the response information can include indication information to indicate the updated value of at least one parameter in the initial PUR transmission configuration.

[0100] For example, the at least one parameter can include a downlink carrier (i.e., the receiving carrier of the PUR SS), that is to say, the change in the coverage level only changes the receiving carrier of the PUR SS.

[0101] Specifically, before the UE enters the idle state, the network configures a set of PUR transmission configurations (i.e., the initial PUR transmission configuration) through RRC dedicated signaling according to the coverage level where the UE is currently located. The initial PUR configuration includes parameters such as uplink carrier index, downlink carrier index, PUSCH repetition times, and timing advance values.

[0102] Furthermore, the network can also configure the downlink carrier set corresponding to each coverage level through system broadcast information or RRC dedicated signaling.

[0103] Due to the mobility of the UE, the coverage level where the UE is located will change. The UE can determine whether the coverage level has changed according to the measurement results. If it is determined that the current coverage level has changed, the UE can use the initial PUR transmission configuration to report the coverage level change indication.

[0104] After reporting the coverage level change indication using the initial PUR transmission configuration, the UE will receive the response information sent by the network in the corresponding PUR search space window. The corresponding PUR search space window is determined according to the downlink carrier index in the initial PUR transmission configuration.

[0105] As an indication in the response information, a specific bit field (i.e., the indication bit) is set in the downlink control information to indicate the downlink carrier index for receiving the PUR feedback information corresponding to the target coverage level. And the downlink carrier index corresponding to the target coverage level is selected from the downlink carrier set corresponding to the target coverage level.

[0106] The UE determines the downlink carrier index for receiving the PUR feedback information corresponding to the target coverage level according to the value of this indication bit in the indication confirmation downlink control information.

[0107] The PUR feedback information is the indication confirmation downlink control information.

[0108] For another example, the at least one parameter may include an uplink carrier and a downlink carrier, that is, when the coverage level changes, it is necessary to indicate the PUR transmission carrier and the receiving carrier of the PUR SS.

[0109] Specifically, before the UE enters the idle state, the network configures a set of PUR transmission configurations (i.e., the initial PUR transmission configuration) through RRC dedicated signaling according to the coverage level where the UE is currently located. The initial PUR configuration includes parameters such as uplink carrier index, downlink carrier index, PUSCH repetition times, and timing advance values.

[0110] Furthermore, the network can also configure the downlink carrier set and the uplink carrier set corresponding to each coverage level through system broadcast information or RRC dedicated signaling.

[0111] Due to the mobility of the UE, the coverage level where the UE is located may change, and the UE can determine whether the coverage level has changed according to the measurement results. If it is determined that the current coverage level has changed, the UE can use the initial PUR transmission configuration to report the coverage level change indication.

[0112] After reporting the coverage level change indication using the initial PUR transmission configuration, the UE will receive the response information sent by the network in the corresponding PUR search space window. The corresponding PUR search space window is determined according to the downlink carrier index in the initial PUR transmission configuration.

[0113] Two specific bit fields (i.e., indication bits) are set in the downlink control information as the indication of the response information. One of the bit fields is used to indicate the uplink carrier index for PUR transmission corresponding to the target coverage level, and the other bit field is used to indicate the downlink carrier index for receiving PUR feedback information corresponding to the target coverage level. Moreover, the uplink carrier index corresponding to the target coverage level indicated by the indication bits is selected from the uplink carrier set corresponding to the target coverage level. Similarly, the downlink carrier index corresponding to the target coverage level indicated by the indication bits is selected from the downlink carrier set corresponding to the target coverage level.

[0114] The UE determines the uplink carrier index for PUR transmission and the downlink carrier index for receiving PUR feedback information corresponding to the target coverage level according to the values of these two bit fields in the indication confirmation downlink control information.

[0115] In response to receiving the response information, in step S103, the UE can determine the parameters to be updated and the specific values to be updated according to the indication information in the response information, and then update the initial PUR transmission configuration. Further, after updating the initial PUR transmission configuration, the updated initial PUR transmission configuration can be used for data transmission.

[0116] As described above, by adopting this implementation solution, the UE side can implement the PUR transmission-related configuration based on the coverage level to ensure that the UE can maintain effective data transmission with the network when the coverage level changes. Specifically, different coverage levels correspond to different PUR transmission configurations. Further, when the UE determines that the coverage level has changed, it requests to switch to using the target PUR transmission configuration associated with the target coverage level for data transmission by reporting the current coverage level change. Further, according to the indication of the response information, the UE can timely use the target PUR transmission configuration to continue data transmission when the network activates the target PUR transmission configuration, so as to maintain an effective data connection with the network at the target coverage level. Further, according to the indication of the response information, the UE can update the initial PUR transmission configuration so as to use the data transmission parameter configuration corresponding to the target coverage level for data transmission.

[0117] Figure 2 It is a schematic structural diagram of a data transmission device according to the first embodiment of the present invention. Those skilled in the art understand that the data transmission device 2 described in this embodiment can be used to implement the above Figure 1 method technical solutions described in the above-mentioned embodiments.

[0118] Specifically, referring to Figure 2 , the data transmission device 2 described in this embodiment may include: a sending module 21, which sends change indication information if it is determined that the coverage level has changed, to indicate that the coverage level has changed to a target coverage level; a receiving module 22, which is used to receive response information, where the response information is used to indicate whether the target PUR transmission configuration associated with the target coverage level is activated, or the response information is used to indicate the updated values of at least one parameter in the initial PUR transmission configuration; a transmission module 23, which continues data transmission according to the response information, using the activated target PUR transmission configuration or the updated initial PUR transmission configuration.

[0119] For more content about the working principle and working mode of the data transmission device 2, reference can be made to the relevant descriptions in the above Figure 1 and will not be elaborated here.

[0120] In a specific implementation, the above-mentioned data transmission device 2 may correspond to a chip with data transmission function in a user equipment, or correspond to a chip with data processing function, such as a System-On-a-Chip (SOC for short), a baseband chip, etc.; or correspond to a chip module including a chip with data transmission function in a user equipment; or correspond to a chip module with a chip having data processing function, or correspond to a user equipment.

[0121] Figure 3 It is a flowchart of a data transmission method according to the second embodiment of the present invention.

[0122] This implementation scheme can be applied to a terrestrial network scenario.

[0123] This implementation scheme can be executed by the network side, such as by a network device on the network side. For example, the network device may include a base station.

[0124] In a specific implementation, the data transmission method provided in the following steps S301 to S304 can be executed by a chip with data transmission function in the network device, or can be executed by a baseband chip in the network device.

[0125] Specifically, referring to Figure 3 , the data transmission method described in this embodiment may include the following steps:

[0126] Step S301: Receive change indication information, where the change indication information is used to indicate that the coverage level of the user equipment changes to a target coverage level;

[0127] Step S302: Determine whether to activate the target PUR transmission configuration associated with the target coverage level, or whether to update the value of at least one parameter in the initial PUR transmission configuration, at least based on the network load;

[0128] Step S303: Generate and send a response message according to the determination result, where the response message is used to indicate whether the target PUR transmission configuration associated with the target coverage level is activated, or the response message is used to indicate the updated value of at least one parameter in the initial PUR transmission configuration;

[0129] Step S304: Receive data using the activated target PUR transmission configuration or the updated initial PUR transmission configuration according to the response message.

[0130] Those skilled in the art understand that steps S301 to S304 can be regarded as execution steps corresponding to steps S101 to S103 in the above Figure 1 shown embodiment, and the two are complementary in specific implementation principles and logics. Therefore, the explanations of the terms involved in this embodiment can refer to Figure 1 the relevant descriptions of the shown embodiment and will not be elaborated here.

[0131] In a specific implementation, the response message can indicate the target PUR transmission configuration corresponding to the target coverage level. That is, the network pre-configures multiple sets of PUR transmission configurations for the UE, and different PUR transmission configurations correspond to different coverage levels. The network activates the corresponding target PUR transmission configuration for the UE according to the target coverage level reported by the UE.

[0132] Correspondingly, before step S301, the data transmission method described in this embodiment may further include steps: determining an initial PUR transmission configuration according to the initial coverage level of the user equipment; sending configuration information, where the configuration information includes multiple sets of PUR transmission configurations and an initial activation indication, and different PUR transmission configurations are associated with different coverage levels.

[0133] The initial coverage level is the coverage level where the user equipment in the connected state is located. For example, the initial coverage level is determined during the period when the user equipment is in the connected state.

[0134] In a variation, the response information may indicate updated data for at least one parameter in the initial PUR coverage level. That is, the network pre-configures a set of PUR transmission configurations (i.e., the initial PUR transmission configuration) for the UE and configures a candidate list for at least one parameter in this set of PUR transmission configurations. Different candidates in the candidate list correspond to different coverage levels. The network selects updated data for at least one parameter for the UE according to the target coverage level reported by the UE and indicates it to the UE through the response information, so that the UE updates the initial PUR transmission configuration.

[0135] Correspondingly, before step S301, the data transmission method described in this embodiment may further include the steps of: determining an initial PUR transmission configuration according to the initial coverage level of the user equipment; sending configuration information, where the configuration information includes the initial PUR transmission configuration and also includes a candidate list for at least one parameter in the initial PUR transmission configuration, and different candidates in the candidate list are associated with different coverage levels.

[0136] Furthermore, for each of the at least one parameter, the candidate list of the parameter may include multiple candidate sets, and different candidate sets are associated with different coverage levels. The updated value of the parameter in the initial PUR transmission configuration indicated by the response information is selected from the candidate set associated with the target coverage level in the candidate list.

[0137] Furthermore, the updated value of the parameter being selected from the candidate set associated with the target coverage level in the candidate list may mean that the updated value of the parameter is selected from the candidate set associated with the target coverage level according to the network load.

[0138] Taking the downlink carrier as an example, after receiving the change indication information, the network determines the corresponding downlink carrier candidate set according to the target coverage level reported by the UE, and then selects a suitable downlink carrier from the set according to the load conditions of each downlink carrier in the candidate set and indicates it to the UE. The UE updates the downlink carrier index in its initial PUR transmission configuration to the downlink carrier index indicated by the network to obtain the updated initial PUR transmission configuration.

[0139] In a specific implementation, the at least one parameter may be selected from: uplink carrier and downlink carrier.

[0140] In a specific implementation, the configuration information may be sent during the period when the user equipment is in the connected state.

[0141] In a specific implementation, the change indication information may include indication information of the target coverage level, or the change indication information may include indication information of the target PUR transmission configuration. Through the change indication information, the network can determine the target PUR transmission configuration that the UE hopes to use.

[0142] In a specific implementation, in step S303, the response information may be sent using the downlink search space window corresponding to the PUR transmission opportunity of the initial PUR transmission configuration.

[0143] In a specific implementation, in step S301, the change indication information may be received using the PUR transmission opportunity of the initial PUR transmission configuration.

[0144] In a specific implementation, the response information may include an indication bit, and whether the target PUR transmission configuration is activated may be determined according to the specific value of the indication bit. Correspondingly, the response information may be carried by DCI.

[0145] In a variant, whether the target PUR transmission configuration is activated may be determined according to whether the indication bit in the response information received this time has flipped compared with the indication bit in the response information received last time. Correspondingly, the response information may be carried by DCI.

[0146] In a variant, the response information may include an indication bit to indicate the updated value of at least one parameter in the initial PUR transmission configuration. Correspondingly, the response information may be carried by DCI.

[0147] In a variant, the response information may include an indication cell to indicate whether the target PUR transmission configuration is activated, or the updated value of at least one parameter in the initial PUR transmission configuration. Correspondingly, the response information may be carried by high-layer signaling.

[0148] In a specific implementation, if the judgment result of step S303 is not to activate the target PUR transmission configuration, the network may send response information indicating no switching of the PUR transmission configuration using the receiving carrier of the PUR SS in the initial PUR transmission configuration. In response to receiving this response information, the UE continues to perform data transmission using the initial PUR transmission configuration.

[0149] For example, when the uplink carrier and / or downlink carrier in the target PUR transmission configuration has a large load, the network may decide not to activate the target PUR transmission configuration.

[0150] For another example, if the current load of all downlink carriers in the downlink carrier set corresponding to the target coverage level is large, the network may decide not to activate the target PUR transmission configuration.

[0151] For example, the response information indicating deactivation can be carried by fallback downlink control information or high-layer signaling.

[0152] In a specific implementation, if the determination result in step S303 is to deactivate the target PUR transmission configuration, the network can send response information indicating the release of the initial PUR transmission configuration through the receiving carrier of the PUR SS in the initial PUR transmission configuration. In response to receiving this response information, the UE can release the initial PUR transmission configuration and enter the random access procedure when subsequent data needs to be sent.

[0153] For example, the response information indicating release can be carried by fallback downlink control information or high-layer signaling.

[0154] Thus, by adopting this implementation solution, the network side can implement the PUR transmission-related configuration based on the coverage level to ensure effective data transmission with the UE when the UE's coverage level changes. Specifically, different coverage levels correspond to different PUR transmission configurations. Further, when it is determined according to the received change indication information that the UE's coverage level has changed, activate the target PUR transmission configuration for the UE so that the UE can maintain an effective data connection with the network using the corresponding target PUR transmission configuration at the target coverage level. Further, when it is determined that the UE's coverage level has changed, update at least one parameter in the initial PUR transmission configuration for the UE so that the UE can perform data transmission using the data transmission parameter configuration corresponding to the target coverage level. Further, measure whether to activate the target coverage transmission configuration or select the specific update value of the parameter to be updated according to the network load to balance the UE's requirements and the network's capabilities and provide a better communication experience for users.
