Description

TECHNICAL FIELD

The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the described technology can be used in the above-mentioned systems and radio technologies, as well as in other systems and radio technologies. The following description describes a New Radio (NR) system for the purpose of example, and NR terminology is used in most of the following description, but these technologies can also be applied to systems other than the NR system, such as a 6th Generation (6G) communication system.

[0147] Figure 1 A block diagram of a wireless communication system to which the embodiments of the present application can be applied is shown. The wireless communication system includes a terminal device 11 and a network side device (or network device) 12. The terminal device 11 can also be referred to as a terminal or a User Equipment (UE). It should be noted that the specific type of the terminal 11 is not limited in the embodiments of the present application. The network side device 12 can be a base station or a core network.

[0148] To enable those skilled in the art to better understand the embodiments of the present application, the following is first described.

[0149] 5G system encapsulates information such as frequency bands occupied in the frequency domain by a physical downlink control channel (PDCCH) and the number of orthogonal frequency division multiplexing (OFDM) symbols occupied in the time domain in a control resource set (CORESET); encapsulates information such as a PDCCH starting OFDM symbol number and a PDCCH monitoring period in a search space (Search Space). The location of the PDCCH can be determined through the CORESET and the Search Space. The control information carried on the PDCCH is called downlink control information (DCI).

[0150] The PDCCH is ultimately mapped to a resource block (RB), but a PDCCH occupies a large number of RBs, and it is not very convenient to describe the resources occupied by the PDCCH in terms of RBs, so the concepts of resource element group (REG) and control channel element (CCE) are introduced. REG represents a resource corresponding to one symbol in the time domain and one RB in the frequency domain. One CCE corresponds to 6 REGs. The resources that can be occupied by the PDCCH and the resources actually occupied by the PDCCH are described in terms of CCEs.

[0151] After the UE determines the candidate time-frequency location of the PDCCH according to the Search Space and the CORESET configuration, the UE does not know the specific CCE on which the PDCCH is sent, so it needs to perform blind detection on the candidate time-frequency location. The PDCCH candidate is the location of the UE PDCCH in the candidate resource. In order to reduce the number of blind detections of the UE, the network will place these PDCCHs according to some rules, and the UE can reduce the number of blind detections according to some rules.

[0152] In the carrier aggregation scenario, NR supports self-scheduling and cross-carrier scheduling. Specifically, in the carrier aggregation scenario, multiple cells can be included, different cells correspond to different carriers, and the network can configure a scheduling cell for a scheduled cell. The DCI of the scheduled cell needs to be obtained from the search space of the scheduling cell.

[0153] The data transmission method provided by the embodiments of the present application will be described in detail in combination with the accompanying drawings and some embodiments and application scenarios.

[0154] AsFigure 2 As shown in the embodiments of the present application, a data transmission method is provided, comprising:

[0155] Step 201: A terminal acquires first indication information, wherein the first indication information is used to indicate the terminal to monitor a first control channel according to a first resource, the first resource is a control channel resource of an Mth generation mobile communication system, the first control channel is used to schedule a first transmission, the first transmission is a data transmission of an Nth generation mobile communication system, M and N are positive integers respectively, and N is greater than M.

[0156] As an implementation manner, the Mth generation mobile communication system is a 5G communication system, and the Nth generation mobile communication system is a 6G communication system.

[0157] The first resource can be understood as one of the control channel resources configured by the 5G network for the 5G UE. The first transmission is a 6G data transmission.

[0158] The first control channel can also be described as first signaling.

[0159] Optionally, the first control channel comprises at least one of a control channel of the Mth generation mobile communication system and a control channel of the Nth generation mobile communication system.

[0160] Optionally, the terminal can determine the first resource as the control channel resource of the 5G communication system implicitly or explicitly through the first indication information.

[0161] For example, the network side device can directly indicate the first resource as the control channel resource of the 5G communication system through a signal element in the first indication information.

[0162] For example, the network side device can implicitly indicate the first resource as the control channel resource of the 5G communication system through the coding mode, subcarrier spacing, control channel search mode, etc. contained in the first indication information.

[0163] Optionally, the terminal acquiring the first indication information comprises the terminal acquiring the first indication information sent by a network side device. The network side device can be a base station. Optionally, the terminal can acquire the first indication information through radio resource control (RRC) signaling.

[0164] The terminal acquires the first indication information, so as to subsequently monitor the first control channel scheduling the first transmission on the first resource based on the first indication information. Step 202: In the case that the terminal monitors the first control channel on the first resource, the first transmission is performed at a first time point.

[0165] The first time point is determined based on a second time point and a first delay duration, the second time point is a time point at which the terminal monitors the first control channel on the first resource, and the first delay duration is a delay duration for the first transmission configured by a network side device or reported by the terminal to the network side device.

[0166] Optionally, the first transmission at the first time point comprises transmitting the first transmission at the first time point, and / or receiving the first transmission at the first time point.

[0167] Optionally, the first time point is determined according to a sum of the second time point and the first delay duration.

[0168] As an implementation manner, the first time point is obtained by adding a preset time duration to the sum of the second time point and the first delay duration, for example, the preset time duration comprises a preparation time. The preparation time is a preparation time of the UE for data transmission after receiving the first control channel.

[0169] Optionally, the first delay duration is determined according to a switching time of the terminal between the Nth generation mobile communication system and the Mth generation mobile communication system.

[0170] For example, the switching time comprises at least one of the following:

[0171] a switching time of the terminal between a physical layer of the Nth generation mobile communication system and a physical layer of the Mth generation mobile communication system;

[0172] a switching time of the terminal between a radio frequency channel of the Nth generation mobile communication system and a radio frequency channel of the Mth generation mobile communication system.

[0173] In step 202, in the case that the terminal monitors the first control channel on the first resource, a time point for the first transmission is determined based on a first delay duration, that is, after monitoring the first control channel, the first delay duration is added to ensure that the terminal has enough time to switch between the Mth generation communication system and the Nth generation communication system.

[0174] In some embodiments of the present application, for a part of the UEs, the first delay duration may be due to the difference between the physical layer of the 6G communication system for data processing and the physical layer of the 5G communication system for data processing, for example, the channel coding adopted by the two communication system physical layers is different, so when the UE monitors the first control channel on the control channel resource of the 5G system and performs 6G transmission based on the monitored first control channel, the first delay duration needs to be added after receiving the first control channel to ensure that the terminal has enough time to switch the physical layer. Or, for a part of the UEs, the first delay duration may be due to the difference between the radio frequency channel of the 6G communication system and the radio frequency channel of the 5G communication system, so when the UE monitors the first control channel on the control channel resource of the 5G system and performs 6G transmission based on the monitored first control channel, the first delay duration needs to be added after receiving the first control channel to ensure that the terminal has enough time to switch the radio frequency channel. Or, for a part of the UEs, the first delay duration includes the switching time between the physical layers and the switching time between the radio frequency channels to ensure that the terminal has enough time to switch the radio frequency channel and the physical layer.

[0175] In the embodiments of the present application, the terminal obtains first indication information, and the first indication information is used to instruct the terminal to monitor the first control channel according to the first resource; and in the case that the terminal monitors the first control channel on the first resource, the first transmission is performed at a first time. Through the above-mentioned scheme, after the terminal monitors the first control channel on the control system resource of the Mth generation mobile communication system, the terminal performs the data transmission of the Nth generation communication system scheduled by the first control channel based on the first delay duration. Through the first delay duration, the switching between the Mth generation communication system and the Nth generation communication system of the terminal can be effectively guaranteed, thereby achieving the purpose that the terminal can use the resource of the Mth generation communication system to perform the data transmission of the Nth generation communication system.

[0176] Optionally, in the case that the terminal monitors the first control channel on the first resource, the first transmission is performed at a first time, including:

[0177] In the case that the terminal monitors the first control channel on the first resource, the first transmission is performed at a first time corresponding to the first control channel;

[0178] Or, in the case that the terminal monitors each of the first control channels on the first resource, the first transmission is performed at a first time corresponding to each of the first control channels;

[0179] The first time corresponding to the first control channel is determined based on the first delay duration and a second time at which the terminal monitors the first control channel.

[0180] For example, if a terminal detects the first control channel on the first resource at times T1, T2, and T3 respectively, where T1 is the time when the terminal detects the first first control channel on the first resource, then for the first control channel detected at time T1, the terminal can perform the first transmission based on the sum of time T1 and the first delay duration. However, for the first control channels detected at times T2 and T3, no additional first delay duration is required for the first transmission, and the first transmission can be performed directly based on time T2 and T3. Alternatively, another terminal may require an additional first delay duration after detecting each first control channel before performing the first transmission, so it needs to perform its respective first transmission based on the sum of time T1 and the first delay duration, the sum of time T2 and the first delay duration, and the sum of time T3 and the first delay duration.

[0181] In this embodiment, the terminal can perform a first transmission based on its own capabilities or internal implementation. When the first first control channel is detected on the first resource, the terminal performs a first transmission based on the time of detection of the first control channel and the first delay duration. Alternatively, when each first control channel is detected on the first resource, the terminal performs a first transmission based on the time of each detection of the first control channel and the first delay duration. This ensures that the terminal has sufficient time to switch between the M-generation communication system and the N-generation communication system, and also enables some high-capability terminals to reduce transmission waiting latency and improve transmission efficiency.

[0182] Optionally, the first control channel includes the control channel of the Mth generation mobile communication system and the control channel of the Nth generation mobile communication system; the method further includes:

[0183] The terminal determines the resource location occupied by the control channel of the Mth generation mobile communication system based on the first parameter and the first resource, wherein the first parameter is used to determine the resource occupied by the control channel of the Mth generation mobile communication system in the first resource;

[0184] The terminal determines the resource location occupied by the control channel of the Nth generation mobile communication system based on the second parameter and the first resource, wherein the second parameter is used to determine the resource occupied by the control channel of the Nth generation mobile communication system in the first resource;

[0185] Wherein, the first parameter and the second parameter are parameters configured by the network-side device, or are parameters agreed upon by the protocol, and the first parameter and the second parameter are different.

[0186] As an implementation manner, the first parameter is a cross-carrier indication parameter of the 5G communication system, and the second parameter is a cross-carrier indication parameter of the 6G communication system. The existing cross-carrier indication parameter is used to determine the CCE occupied by the control channel candidate. Alternatively, the cross-carrier indication parameter can also be understood as a carrier parameter.

[0187] For example, the value range of the cross-carrier indication parameter of the 5G communication system is 0-7, and the value range of the cross-carrier indication parameter of the 6G communication system is 8-16. Therefore, the resource positions occupied by the control channels of the Mth generation communication system and the Nth generation mobile communication system can be distinguished by the value of the cross-carrier indication parameter.

[0188] In the embodiment of the application, if the terminal can monitor the control channel of the Mth generation mobile communication system and the control channel of the Nth generation mobile communication system at the same time, the resource positions occupied by the control channels of the Mth generation communication system and the Nth generation mobile communication system can be distinguished by multiplexing the cross-carrier indication parameter. Of course, the first parameter and the second parameter can also be other parameters configured by the network side device in addition to the cross-carrier indication parameter. For example, the first parameter and the second parameter are newly added, the parameter value of the first parameter is 0, and the parameter value of the second parameter is 1. Based on the first parameter and the second parameter, the resource positions occupied by the control channels of the Mth generation communication system and the Nth generation mobile communication system can be distinguished.

[0189] Alternatively, the method of the embodiment of the application further comprises:

[0190] The terminal acquires second indication information, and the second indication information is used to instruct the terminal to monitor a second control channel on the first resource, and the second control channel is used to schedule a second transmission, and the second transmission includes data transmission of the Mth generation mobile communication system or data transmission of the Nth generation mobile communication system.

[0191] In the case that the terminal monitors the second control channel on the first resource, data transmission of the Mth generation mobile communication system is performed at a third time, or data transmission of the Nth generation mobile communication system is performed at a fourth time.

[0192] The third time is determined based on the sum of a fifth time and a second delay duration.

[0193] The fourth time is determined based on the fifth time, the first delay duration and the second delay duration; optionally, the fourth time is determined based on a sum of the fifth time, the first delay duration and the second delay duration; for example, the fourth time is obtained by adding a preparation time to the sum of the fifth time, the first delay duration and the second delay duration, and the preparation time can be a preparation time of the UE for data transmission after receiving the second control channel. For example, the above-mentioned preparation time can be understood as a preparation time of the UE for 6G data transmission after receiving the 6G control channel, or the preparation time can be understood as a preparation time of the UE for data transmission after receiving the control signaling on the 6G control channel resource.

[0194] The fifth time is a time when the terminal monitors the second control channel on the first resource; and the second delay duration is a delay duration configured by the network side device or reported by the terminal to the network side device for the second transmission.

[0195] Optionally, the second delay duration is determined according to a decoding time of the second control channel.

[0196] Optionally, the step of the terminal obtaining the second indication information includes that the terminal obtains the second indication information sent by the network side device, and the terminal can obtain the second indication information through RRC signaling.

[0197] The terminal monitors the second control channel capable of simultaneously scheduling data transmission of the Mth generation mobile communication system and data transmission of the Nth generation mobile communication system on the first resource based on the indication of the second indication information. For example, the second control channel capable of simultaneously scheduling 5G data transmission and 6G data transmission is monitored.

[0198] In some embodiments of the present application, the second control channel can explicitly or implicitly indicate that the second transmission is 5G data transmission or 6G data transmission. For example, the second control channel is indicated by a first indication field. Optionally, the first indication field is 1 bit, and when the value of the 1 bit is 1, the first indication field is used to indicate that the above-mentioned second transmission is 5G data transmission. When the value of the 1 bit is 0, the first indication field is used to indicate that the above-mentioned second transmission is 6G data transmission. For another example, the second control channel can implicitly indicate the above-mentioned 5G data transmission or 6G data transmission through at least one of a time domain indication field, a frequency domain indication field, a coding indication field and a modulation indication field.

[0199] In the embodiment of the present application, in the case that the terminal monitors the second control channel on the first resource, if the second control channel schedules data transmission of the Mth generation mobile communication system, no switching between the two communication systems is needed, the terminal obtains the third time based on the time when the second control channel is monitored and the decoding time of the second control channel, and performs data transmission of the Mth generation mobile communication system at the third time.

[0200] In the case that the terminal monitors the second control channel on the first resource, if the second control channel schedules data transmission of the Nth generation mobile communication system, switching between the two communication systems is needed, the terminal obtains the fourth time based on the time when the second control channel is monitored, the decoding time of the second control channel and the switching time between the two communication systems, and performs data transmission of the Nth generation mobile communication system at the fourth time.

[0201] The second control channel can schedule data transmission of the Mth generation mobile communication system and data transmission of the Nth generation mobile communication system, and the data transmission scheduled by the second control channel can be data transmission of the Mth generation mobile communication system or data transmission of the Nth generation mobile communication system, that is, the data transmission scheduled by the second control channel is dynamically changed, and the data transmission of the Mth generation mobile communication system and the data transmission of the Nth generation mobile communication system can use different encoding modes, and the terminal needs to obtain the encoding mode for decoding data after the second control channel is decoded. Therefore, by increasing the second delay time, the terminal can have enough time to obtain the decoding mode of the data transmission scheduled by the second control channel after receiving the second control channel.

[0202] Optionally, the method of the embodiment of the present application further comprises:

[0203] In the case that the first condition is met, the terminal monitors the control channel on the second resource, and the second resource is a control channel resource of the Nth generation mobile communication system.

[0204] The first condition includes at least one of the following:

[0205] The terminal does not monitor the first control channel within a preset time period.

[0206] The monitoring time of the terminal on the first control channel is greater than or equal to a time threshold.

[0207] The first condition can also be other conditions configured by the network side device, which is not limited in the embodiment of the present application.

[0208] For example, the second resource is a 6G control channel resource configured by the network for the UE.

[0209] The preset time length and the time threshold can be configured by a network or predefined by a protocol.

[0210] In some embodiments of the present application, if the terminal does not detect the first control channel within the preset time length, and / or the monitoring time of the terminal on the first control channel is greater than or equal to the time threshold, it indicates that the terminal does not need to continue to monitor the control channel on the first resource of the Mth generation mobile communication system, and needs to switch to the second resource of the Nth generation mobile communication system to monitor the control channel, thereby enabling the terminal to switch between the control channel resources of the two mobile communication systems.

[0211] For example, if the terminal does not monitor the first control channel on the control channel resource of 5G within the preset time length, the terminal can give up monitoring the first control channel on the control channel resource of 5G and monitor the first control channel on the control channel resource of 6G.

[0212] In the embodiments of the present application, under the condition that the first condition is met, the terminal can return to the second resource from the first resource to monitor the control channel, for example, under the condition that the first condition is met, the terminal can return to the control channel resource of 6G from the control channel resource of 5G to monitor the control channel.

[0213] Optionally, the method of the embodiments of the present application further comprises:

[0214] Under the condition that the number of times of monitoring the control channel by the terminal is greater than the monitoring number threshold, or under the condition that the maximum number of non-overlapping control channel elements in the control channel elements corresponding to the candidate resources of the control channel is greater than the preset threshold, the terminal monitors the control channel according to a first preset rule, the control channel including the control channel of the Nth generation mobile communication system and the control channel of the Mth generation mobile communication system.

[0215] The first preset rule includes:

[0216] selecting the first resource to monitor the control channel;

[0217] Or, among the first resource and the second resource, the resource corresponding to the first search space is selected to monitor the control channel, the first search space being the search space with a larger or smaller identifier among the search spaces corresponding to the first resource and the second resource, or the identifier of the first search space being smaller than an identifier threshold, the identifier threshold being determined according to the monitoring capability of the terminal on the control channel.

[0218] The second resource is the control channel resource of the Nth generation mobile communication system.

[0219] Optionally, the control channel element (CCE) can also be described as a control channel resource unit or a frequency domain resource unit.

[0220] Optionally, the above monitoring can be understood as blind detection, that is, the above monitoring times can be described as blind detection times, and the monitoring of the control channel can be described as blind detection of the control channel.

[0221] Optionally, the above identifier in the embodiments of the present application can be represented by an index, a number, or an ID, etc.

[0222] In some embodiments of the present application, the monitoring times threshold value can be the maximum monitoring times of the control channel by the terminal. When the monitoring times of the control channel by the terminal is greater than the maximum monitoring times, it can be understood that the monitoring times of the control channel by the terminal has exceeded the UE capability, at this time, the behavior of the terminal in this scenario needs to be defined, or when the maximum number of non-overlapping control channel elements in the control channel elements corresponding to the candidate resources of the control channel is greater than the number specified in the protocol, the behavior of the terminal in this scenario also needs to be defined.

[0223] The first preset rule enables the terminal to determine the operation to be taken by the terminal when the monitoring times of the control channel by the terminal exceeds the UE capability, or the first preset rule enables the terminal to determine the operation to be taken by the terminal when the maximum number of non-overlapping control channel elements in the control channel elements is greater than the preset threshold value, so that the terminal and the network side can have a consistent understanding of the behavior of the terminal.

[0224] In the embodiments of the present application, in the case that the monitoring times of the control channel by the terminal is greater than the monitoring times threshold value, or in the case that the maximum number of non-overlapping control channel elements in the control channel elements corresponding to the candidate resources of the control channel is greater than the preset threshold value, the monitoring of the second resource is preferentially discarded, that is, the first resource is selected for the monitoring of the control channel, or the resource corresponding to the search space with a larger or smaller search space in the search spaces corresponding to the first resource and the second resource is selected for the monitoring of the control channel, thereby, when the monitoring times of the control channel, such as the maximum blind detection times, or the maximum number of non-overlapping control channel elements exceeds the value specified in the protocol or exceeds the UE capability, the terminal can perform corresponding processing based on the first preset rule.

[0225] In the embodiment of the present application, the terminal acquires first indication information, the first indication information is used to indicate the terminal to monitor the first control channel according to the first resource; in the case that the terminal monitors the first control channel on the first resource, the first transmission is performed at the first time. Through the above-mentioned scheme, after the terminal monitors the first control channel on the control system resource of the Mth generation mobile communication system, the data transmission of the Nth generation communication system scheduled by the first control channel is performed based on the first delay duration, and the terminal can be effectively guaranteed to switch between the Mth generation communication system and the Nth generation communication system through the first delay duration, thereby realizing the purpose that the terminal can use the resource of the Mth generation communication system to perform the data transmission of the Nth generation communication system, so that the Nth generation communication system can share the resource of the Mth generation communication system to perform the data transmission, thereby effectively improving the spectrum utilization efficiency.

[0226] As shown in Figure 3 The embodiment of the present application also provides a data transmission method, which comprises:

[0227] Step 301: a network side device sends first indication information, the first indication information is used to indicate a terminal to monitor a first control channel according to a first resource, the first resource is a control channel resource of an Mth generation mobile communication system, the first control channel is used to schedule a first transmission, the first transmission is a data transmission of an Nth generation mobile communication system, M and N are positive integers respectively, and N is greater than M.

[0228] As an implementation manner, the Mth generation mobile communication system is a 5G communication system, and the Nth generation mobile communication system is a 6G communication system.

[0229] The first resource can be understood as one of the control channel resources configured by the 5G network for the 5G UE. The first transmission is a 6G data transmission.

[0230] The first control channel can also be described as first signaling.

[0231] Optionally, the first control channel comprises at least one of a control channel of the Mth generation mobile communication system and a control channel of the Nth generation mobile communication system.

[0232] Optionally, the network side device sends the first indication information comprises that the network side device sends the first indication information to the terminal, and the network side device can send the first indication information through RRC signaling.

[0233] Optionally, the network side device can implicitly or explicitly indicate the first resource as the control channel resource of the 5G communication system through the first indication information.

[0234] Exemplarily, the network-side device can directly indicate the first resource as the control channel resource of the 5G communication system through a signal element in the first indication information.

[0235] Exemplarily, the network-side device can implicitly indicate the first resource as the control channel resource of the 5G communication system through the coding mode, the subcarrier spacing, the control channel search mode, etc. contained in the first indication information.

[0236] The network-side device sends the first indication information, so that the terminal subsequently monitors the first control channel for scheduling the first transmission on the first resource based on the first indication information.

[0237] Step 302: sending the first control channel on the first resource and performing the first transmission at a first time;

[0238] The first time is determined based on a second time and a first delay duration, the second time is the time when the terminal monitors the first control channel on the first resource, and the first delay duration is a delay duration for the first transmission configured by the network-side device or reported by the terminal to the network-side device.

[0239] Optionally, the performing the first transmission at the first time includes sending the first transmission at the first time, or receiving the first transmission at the first time.

[0240] Optionally, the first time is determined according to the sum of the second time and the first delay duration.

[0241] As an implementation manner, the first time is obtained by adding a preset duration to the sum of the second time and the first delay duration, for example, the preset duration includes a preparation time. The preparation time is the preparation time of the UE after receiving the first control channel for data transmission.

[0242] Optionally, the first delay duration is determined according to the switching time of the terminal between the Nth generation mobile communication system and the Mth generation mobile communication system.

[0243] Exemplarily, the switching time includes at least one of the following:

[0244] The switching time of the terminal between the physical layer of the Nth generation mobile communication system and the physical layer of the Mth generation mobile communication system;

[0245] The switching time of the terminal between the radio frequency channel of the Nth generation mobile communication system and the radio frequency channel of the Mth generation mobile communication system.

[0246] The first time point in the step 302 is obtained based on the first delay duration, and the first delay duration is increased to ensure that the terminal has sufficient time to switch between the Mth generation communication system and the Nth generation communication system.

[0247] In some embodiments of the present application, for a part of the UEs, the first delay duration may be due to the physical layer for data processing of the 6G communication system being different from the physical layer for data processing of the 5G communication system, for example, the channel coding adopted by the two communication systems is different, so when the UE monitors the first control channel on the control channel resource of the 5G system and performs 6G transmission based on the monitored first control channel, the first delay duration needs to be added after the first control channel is received to ensure that the terminal has sufficient time to switch the physical layer. Or, for a part of the UEs, the first delay duration may be due to the radio frequency channel of the 6G communication system being different from the radio frequency channel of the 5G communication system, so when the UE monitors the first control channel on the control channel resource of the 5G system and performs 6G transmission based on the monitored first control channel, the first delay duration needs to be added after the first control channel is received to ensure that the terminal has sufficient time to switch the radio frequency channel. Or, for a part of the UEs, the first delay duration includes the switching time between the physical layers and the switching time between the radio frequency channels to ensure that the terminal has sufficient time to switch the radio frequency channels and the physical layers.

[0248] In the embodiments of the present application, the network side device sends first indication information, and the first indication information is used to instruct the terminal to monitor the first control channel according to the first resource; the first control channel is sent on the first resource, and the first transmission is performed at the first time point. Through the above-mentioned scheme, after the terminal monitors the first control channel on the control system resource of the Mth generation mobile communication system, the terminal performs data transmission of the Nth generation communication system scheduled by the first control channel based on the first delay duration. Through the first delay duration, the switching between the Mth generation communication system and the Nth generation communication system of the terminal can be effectively ensured, thereby achieving the purpose that the terminal can perform data transmission of the Nth generation communication system by using the resource of the Mth generation communication system.

[0249] Optionally, the first control channel includes a control channel of the Mth generation mobile communication system and a control channel of the Nth generation mobile communication system; the method further includes:

[0250] According to the first parameter and the first resource, a resource position occupied by the control channel of the Mth generation mobile communication system is determined, wherein the first parameter is used to determine the resource occupied by the control channel of the Mth generation mobile communication system in the first resource.

[0251] determining a resource position occupied by a control channel of the Nth-generation mobile communication system according to the second parameter and the first resource, wherein the second parameter is used to determine the resource occupied by the control channel of the Nth-generation mobile communication system in the first resource;

[0252] The first parameter and the second parameter are parameters configured by a network side device or parameters agreed by a protocol, and the first parameter and the second parameter are different.

[0253] As an implementation manner, the first parameter is a cross-carrier indication parameter of the 5G communication system, and the second parameter is a cross-carrier indication parameter of the 6G communication system. The existing cross-carrier indication parameter is used to determine a CCE occupied by a control channel candidate. Alternatively, the cross-carrier indication parameter can also be understood as a carrier parameter.

[0254] For example, the value range of the cross-carrier indication parameter of the 5G communication system is 0-7, and the value range of the cross-carrier indication parameter of the 6G communication system is 8-16. Therefore, the resource positions occupied by the control channel of the Mth-generation communication system and the control channel of the Nth-generation mobile communication system can be distinguished by the value of the cross-carrier indication parameter.

[0255] In the embodiments of the present application, if the terminal can simultaneously monitor the control channel of the Mth-generation mobile communication system and the control channel of the Nth-generation mobile communication system, the resource positions occupied by the control channel of the Mth-generation communication system and the control channel of the Nth-generation mobile communication system can be distinguished by multiplexing the cross-carrier indication parameter. Of course, the first parameter and the second parameter can also be other parameters configured by the network side device in addition to the cross-carrier indication parameter. For example, the first parameter and the second parameter are newly added, the parameter value of the first parameter is 0, and the parameter value of the second parameter is 1. Based on the first parameter and the second parameter, the resource positions occupied by the control channel of the Mth-generation communication system and the control channel of the Nth-generation mobile communication system can be distinguished.

[0256] Alternatively, the method of the embodiments of the present application further comprises:

[0257] sending second indication information, wherein the second indication information is used to instruct the terminal to monitor a second control channel on the first resource;

[0258] sending a second control channel on the first resource, wherein the second control channel is used to schedule a second transmission, and the second transmission includes data transmission of the Mth-generation mobile communication system or data transmission of the Nth-generation mobile communication system;

[0259] performing data transmission of the Mth-generation mobile communication system at a third time, or performing data transmission of the Nth-generation mobile communication system at a fourth time;

[0260] The third time point is determined based on a sum of the fifth time point and the second delay duration.

[0261] The fourth time point is determined based on the fifth time point, the first delay duration and the second delay duration; for example, the fourth time point is determined based on a sum of the fifth time point, the first delay duration and the second delay duration; for example, the fourth time point is obtained by adding a preparation time to the sum of the fifth time point, the first delay duration and the second delay duration, and the preparation time can be a preparation time for data transmission of the UE after receiving the second control channel. For example, the above preparation time can be understood as a preparation time for 6G data transmission of the UE after receiving the 6G control channel, or the preparation time can be understood as a preparation time for data transmission of the UE after receiving the control signaling on the 6G control channel resource.

[0262] The fifth time point is a time at which the terminal monitors the second control channel on the first resource; and the second delay duration is a delay duration configured by the network side device or reported by the terminal to the network side device for the second transmission.

[0263] Optionally, the second delay duration is determined according to a decoding time of the second control channel.

[0264] The network side device sends the second indication information, so that the terminal monitors the second control channel capable of simultaneously scheduling data transmission of the Mth generation mobile communication system and data transmission of the Nth generation mobile communication system on the first resource based on an indication of the second indication information. For example, the second control channel capable of simultaneously scheduling 5G data transmission and 6G data transmission is monitored.

[0265] In some embodiments of the present application, the second control channel can explicitly or implicitly indicate that the second transmission is 5G data transmission or 6G data transmission. For example, the second control channel is indicated by a first indication field. Optionally, the first indication field is 1 bit, and when the value of the 1 bit is 1, the first indication field is used to indicate that the above-mentioned second transmission is 5G data transmission. When the value of the 1 bit is 0, the first indication field is used to indicate that the above-mentioned second transmission is 6G data transmission. For another example, the second control channel can implicitly indicate the above-mentioned 5G data transmission or 6G data transmission by at least one of a time domain indication field, a frequency domain indication field, a coding indication field and a modulation indication field.

[0266] The second control channel can schedule data transmission of the Mth generation mobile communication system and data transmission of the Nth generation mobile communication system. The data transmission scheduled by the second control channel can be data transmission of the Mth generation mobile communication system or data transmission of the Nth generation mobile communication system, that is, the data transmission scheduled by the second control channel is dynamically changed. The data transmission of the Mth generation mobile communication system and the data transmission of the Nth generation mobile communication system can use different coding modes. The terminal needs to obtain the coding mode for decoding data after decoding the second control channel. Therefore, by increasing the second delay time length, the terminal can have sufficient time to obtain the coding mode of the data transmission scheduled by the second control channel after receiving the second control channel.

[0267] Optionally, the method of the embodiment of the application further includes:

[0268] In the case of satisfying the second condition, a control channel is transmitted on a second resource, and the second resource is a control channel resource of the Nth generation mobile communication system.

[0269] The second condition includes at least one of the following:

[0270] The network side device does not transmit the first control channel within a preset time length, that is, the terminal does not monitor the first control channel within the preset time length.

[0271] The monitoring time length of the terminal for the first control channel is greater than or equal to a time threshold.

[0272] Optionally, the second condition is substantially the same as the content of the first condition.

[0273] Optionally, the network side device can estimate the monitoring time length of the terminal for the first control channel.

[0274] For example, the second resource is a 6G control channel resource configured by the network for the UE.

[0275] The preset time length and the time threshold can be configured by the network or predefined by a protocol.

[0276] In some embodiments of the application, if the terminal does not detect the first control channel within the preset time length and / or the monitoring time length of the terminal for the first control channel is greater than or equal to the time threshold, it indicates that the terminal does not need to continue to monitor the control channel on the first resource of the Mth generation mobile communication system and needs to switch to the second resource of the Nth generation mobile communication system to monitor the control channel. Therefore, the terminal can switch between the control channel resources of the two mobile communication systems. Correspondingly, the network side device transmits the control channel on the second resource in the case of satisfying the second condition.

[0277] For example, if the terminal does not monitor the first control channel on the control channel resource of the 5G within a preset time length, the network side device can give up sending the first control channel on the control channel resource of the 5G and send the first control channel on the control channel resource of the 6G.

[0278] In the embodiments of the present application, under the condition of meeting the first condition, the network side device can return to the second resource from the first resource to send the control channel. For example, under the condition of meeting the second condition, the network side device can return to the 6G control channel resource from the 5G control channel resource to send the control channel.

[0279] Optionally, the method of the embodiments of the present application further comprises:

[0280] Under the condition that the number of times of monitoring the control channel by the terminal is greater than the threshold value of the number of times of monitoring, or under the condition that the maximum number of non-overlapping control channel elements in the candidate resource of the control channel is greater than the preset threshold value, the control channel is sent according to a second preset rule;

[0281] The second preset rule comprises:

[0282] The first resource is selected to send the control channel;

[0283] Or, among the first resource and the second resource, the resource corresponding to the first search space is selected to send the control channel, the first search space being the search space with a larger or smaller identifier among the search spaces corresponding to the first resource and the second resource, or the identifier of the first search space being smaller than an identifier threshold value, the identifier threshold value being determined according to the monitoring capability of the terminal for the control channel;

[0284] The second resource is the control channel resource of the Nth generation mobile communication system.

[0285] Optionally, the second preset rule is substantially the same as the above-mentioned first preset rule.

[0286] Optionally, the control channel element (CCE) can also be described as a control channel resource unit or a frequency domain resource unit.

[0287] Optionally, the above-mentioned identifier in the embodiments of the present application can be represented by a number, an index or an ID, etc. Optionally, the above-mentioned monitoring can be understood as blind detection, i.e. the above-mentioned number of times of monitoring can be described as the number of times of blind detection, and the above-mentioned monitoring of the control channel can be described as blind detection of the control channel.

[0288] In some embodiments of the present application, the above-mentioned monitoring times threshold value can be the maximum monitoring times of the terminal to the control channel, and the monitoring times of the terminal to the control channel greater than the maximum monitoring times can be understood as that the monitoring times of the terminal to the control channel have exceeded the capability of the UE, at this time, the behavior of the terminal in this scenario needs to be defined, or when the maximum number of non-overlapping control channel elements in the control channel elements corresponding to the candidate resources of the control channel is greater than the number specified in the protocol, the behavior of the terminal in this scenario also needs to be defined.

[0289] The first preset rule enables the terminal to determine the operation of the terminal when the monitoring times of the terminal to the control channel exceed the capability of the UE, or the first preset rule enables the terminal to determine the operation of the terminal when the maximum number of non-overlapping control channel elements in the control channel elements is greater than the preset threshold value, so that the terminal and the network side can have a consistent understanding of the behavior of the terminal.

[0290] In the embodiments of the present application, in the case that the monitoring times of the terminal to the control channel are greater than the monitoring times threshold value, or in the case that the maximum number of non-overlapping control channel elements in the control channel elements corresponding to the candidate resources of the control channel is greater than the preset threshold value, the transmission of the control channel on the second resource is preferentially discarded, that is, the first resource is selected for the transmission of the control channel, or the resource corresponding to the search space with a larger or smaller search space in the search spaces corresponding to the first resource and the second resource is identified for the transmission of the control channel, thereby, when the monitoring times of the control channel, such as the maximum blind detection times, or the maximum number of non-overlapping control channel elements, exceed the value specified in the protocol or exceed the capability of the UE, the network side device can perform corresponding processing based on the second preset rule.

[0291] Optionally, the first transmission is performed at the first time, comprising:

[0292] In the case that the terminal monitors the first first control channel on the first resource, the first transmission is performed at the first time corresponding to the first control channel;

[0293] Or, in the case that the terminal monitors each first control channel on the first resource, the first transmission is performed at the first time corresponding to each first control channel;

[0294] The first time corresponding to the first control channel is determined based on a first delay duration and a second time at which the terminal monitors the first control channel.

[0295] In the embodiment of the present application, the network side device performs first transmission at a first time point in the case that the terminal monitors the first control channel on the first resource; or performs the first transmission at the first time point corresponding to each of the first control channels in the case that the terminal monitors each of the first control channels on the first resource, so that the terminal can perform the first transmission based on the terminal capability or the terminal internal implementation when monitoring the first control channel on the first resource based on the time point of monitoring the first control channel and the first delay duration, or perform the first transmission based on the time point of monitoring the first control channel and the first delay duration each time the first control channel is monitored, so as to ensure that the terminal has sufficient time to switch between the Mth generation communication system and the Nth generation communication system, and also reduce the transmission waiting time delay of the terminal with strong capability and improve the transmission efficiency.

[0296] In the embodiment of the present application, the network side device sends first indication information, and the first indication information is used to instruct the terminal to monitor the first control channel based on the first resource; the first control channel is sent on the first resource, and the first transmission is performed at the first time point. Through the above scheme, after the terminal monitors the first control channel on the control system resource of the Mth generation mobile communication system, the terminal performs the data transmission of the Nth generation communication system scheduled by the first control channel based on the first delay duration, and the first delay duration can effectively ensure the switching between the Mth generation communication system and the Nth generation communication system, thereby achieving the purpose that the terminal can perform the data transmission of the Nth generation communication system by using the resource of the Mth generation communication system, so that the Nth generation communication system can share the resource of the Mth generation communication system to perform data transmission, thereby effectively improving the spectrum utilization efficiency.

[0297] The data transmission method of the present application will be described in detail in combination with the embodiments below, and the Mth generation mobile communication system is taken as the 5G communication system and the Nth generation mobile communication system is taken as the 6G communication system in the following embodiments.

[0298] Embodiment one:

[0299] This embodiment one includes:

[0300] Step 1: The UE receives the first indication information sent by the network side device, and the first indication information is used to instruct the terminal to monitor the first control channel on the first resource. The first resource is the control channel resource of the 5G communication system, and the first resource includes at least one of the search space and the control resource set.

[0301] Optionally, the network side device can implicitly or explicitly indicate the first resource as the control channel resource of the 5G communication system through the first indication information.

[0302] For example, the network-side device can directly indicate the first resource as the control channel resource of the 5G communication system through a signal element in the first indication information.

[0303] For example, the network-side device can implicitly indicate the first resource as the control channel resource of the 5G communication system through the encoding mode, subcarrier spacing, control channel search mode, etc. contained in the first indication information.

[0304] Optionally, the network-side device can also indicate that the reference signal for monitoring the first control channel is generated according to the slot number and / or symbol number in the time slot of the 5G or 6G wireless frame. The reference signal can be a demodulation reference signal (DMRS).

[0305] Optionally, the network-side device can also indicate that the sequence initial value of the reference signal is the sequence initial value of the 5G or 6G.

[0306] Optionally, the network-side device can configure the terminal with the control channel resources of the 5G and 6G at the same time. Then the network-side device can indicate the UE to monitor one of the control channel resources in a dynamic or semi-static manner; or the terminal selects one of the control channel resources for detection based on a predefined criterion. For example, if the UE can detect the synchronization signal block (SSB) of the 5G, the UE monitors the control channel resource of the 5G.

[0307] Step 2: The UE monitors the first control channel on the first resource, the first control channel is used to indicate the UE to perform the first transmission, the first control channel is the control channel of the 5G, and the first transmission is the data transmission of the 6G.

[0308] Step 3: After monitoring the first control channel, the UE performs the first transmission at the first time.

[0309] The first time is obtained based on the sum of the second time, the first delay duration and the preparation time.

[0310] Optionally, the preparation time is the preparation time of the UE for the 6G data transmission after receiving the 6G control channel. Alternatively, the preparation time is the preparation time of the UE for the 6G data transmission after receiving the 6G control channel on the 6G control channel resource.

[0311] Optionally, the first delay duration is reported by the UE or configured by the network side or predefined by the protocol.

[0312] Optionally, the first control channel is the first control channel monitored by the UE on the first resource after receiving the first indication information.

[0313] In this embodiment, the terminal uses the 5G CORESET to detect the 5G physical downlink control channel (PDCCH) for scheduling the 6G physical downlink shared channel (PDSCH) or the physical uplink shared channel (PUSCH). Since 5G and 6G use different data encoding methods or different physical layers for data processing, the UE needs time to switch the internal software and hardware, so the scheduling delay may be different from the 6G single scheduling delay or the 5G single scheduling delay. Therefore, the first delay duration needs to be indicated at the first cross-RAT scheduling or each cross-RAT scheduling, to represent that the scheduling delay of the 5G control channel scheduling the 6G data transmission is increased by the first delay duration based on the scheduling delay of the 6G control channel scheduling the 6G data transmission.

[0314] Embodiment two:

[0315] This embodiment two includes:

[0316] Step 1: The UE receives the first configuration information sent by the network side device, and the first configuration information is used to indicate that the UE performs control channel monitoring on the first resource, and the control channel includes a 5G control channel and a 6G control channel. The first resource is a control channel resource of a 5G communication system, and the first resource includes at least one of a search space and a control resource set.

[0317] Step 2: The UE receives the second configuration information sent by the network side device, and the second configuration information is used to indicate that the control channel monitored by the UE on the first resource is a 5G control channel or a 6G control channel.

[0318] Optionally, the first configuration information includes the second configuration information. At this time, step 1 and step 2 can be performed simultaneously.

[0319] Step 3: The UE monitors the 5G control channel or the 6G control channel on the first resource according to the second configuration information.

[0320] Optionally, the UE determines the resource position occupied by the 5G control channel in the first resource according to a first parameter, or the UE determines the resource position occupied by the 6G control channel in the first resource according to a second parameter. The first parameter is different from the second parameter.

[0321] The first parameter can be a cross-carrier indication parameter of 5G, and the second parameter can be a cross-carrier indication parameter of 6G. For example, the parameter value of the cross-carrier indication parameter of 5G is less than the parameter value of the cross-carrier indication parameter of 6G.

[0322] Alternatively, the parameter value of the first parameter is 1, and the parameter value of the second parameter is 2.

[0323] Through the first parameter and the second parameter, the UE can distinguish the resource positions occupied by the 5G control channel and the 6G control channel in the first resource.

[0324] Optionally, for a UE that does not support simultaneous monitoring of the 5G control channel and the 6G control channel, the parameter value of the first parameter can be set to zero. If the UE does not support PDCCH dynamic monitoring of 5G and 6G, the network side needs to configure the UE to monitor the 5G control channel or the 6G control channel through RRC or semi-static, at this time, the first parameter can not be needed, or the parameter value of the first parameter can be set to zero.

[0325] Optionally, the network side device can configure the first preset rule, so that, in a case where the number of times of monitoring the control channel by the terminal is greater than a monitoring number threshold, or in a case where the maximum number of non-overlapping control channel elements in the control channel elements corresponding to the candidate resources of the control channel is greater than a preset threshold, the corresponding processing is performed based on the first preset rule. The monitoring number threshold can be the maximum number of times of monitoring the control channel by the UE. For example, if the number of times of monitoring the control channel by the terminal on the first resource is greater than the monitoring number threshold, the UE does not monitor the 5G control channel or does not monitor the 6G control channel, or gives up monitoring the control channel on the search space with a larger or smaller search space identifier in the search spaces corresponding to the 5G control channel and the 6G control channel. Alternatively, the terminal only monitors the search spaces with identifiers less than an identifier threshold, wherein the identifier threshold satisfies that the maximum number of non-overlapping control channel elements in the control channel elements corresponding to the candidate resources of all search spaces with identifiers less than the identifier threshold is less than or equal to the preset threshold, and the maximum number of non-overlapping control channel elements in the control channel elements corresponding to the candidate resources of all search spaces with identifiers not greater than the identifier threshold is greater than the preset threshold. Alternatively, the terminal monitors a first search space set and gives up monitoring a second search space set, the maximum number of non-overlapping control channel elements in the control channel elements corresponding to the candidate resources of the first search space set is less than or equal to the preset threshold, and the maximum number of non-overlapping control channel elements in the control channel elements corresponding to the candidate resources of the second search space set is greater than the preset threshold, wherein the first search space set includes search spaces with identifiers less than an identifier threshold, and the second search space set includes at least one search space with an identifier greater than or equal to the identifier threshold.

[0326] Embodiment three:

[0327] This embodiment three includes:

[0328] Step 1: The UE receives second indication information sent by the network side device, and the second indication information is used to instruct the UE to perform second control channel monitoring on a first resource. The first resource is a control channel resource of a 5G communication system, and the first resource includes at least one of a search space and a control resource set.

[0329] Step 2: The UE receives third configuration information of the network, and the third configuration information is used to instruct the second transmission of the above-mentioned second control channel to include 5G data transmission and 6G data transmission, that is, the second control channel can schedule both 5G data transmission and 6G data transmission. Steps 1 and 2 are not limited in order. They can also be performed simultaneously.

[0330] Step 3: The UE monitors the second control channel on the first resource, and the second control channel instructs the UE to perform second transmission, which is 5G data transmission or 6G data transmission.

[0331] Optionally, the second control channel can also be described as second signaling. If the second control channel is a 5G control channel, at this time, the control channel of the 6G communication system multiplexes the 5G control channel, and the 6G data transmission can be scheduled through the 5G control channel.

[0332] Optionally, the second control channel can indicate the second transmission as 5G data transmission or 6G data transmission in an explicit or implicit manner. For example, the second control channel indicates through a first indication field. Optionally, the first indication field is 1 bit, and when the value of the 1 bit is 1, the first indication field is used to indicate that the above-mentioned second transmission is 5G data transmission. When the value of the 1 bit is 0, the first indication field is used to indicate that the above-mentioned second transmission is 6G data transmission. For another example, the second control channel can implicitly indicate the above-mentioned 5G data transmission or 6G data transmission through at least one of a time domain indication field, a frequency domain indication field, a coding indication field and a modulation indication field.

[0333] Step 4: In the case that the UE monitors the second control channel on the first resource, 5G data transmission is performed at a third time, or 6G data transmission is performed at a fourth time.

[0334] Wherein, the third time is determined based on the sum of the fifth time, the second delay duration;

[0335] The fourth time is determined based on the sum of the fifth time, the first delay duration, the second delay duration and the preparation time;

[0336] The fifth time point is a time at which the terminal monitors the second control channel on the first resource; and the second delay duration is a delay duration configured by a network side device or reported by the terminal to the network side device for the second transmission.

[0337] Optionally, the preparation time can be understood as a preparation time of the UE for 6G data transmission after receiving the 6G control channel, or the preparation time can be understood as a preparation time of the UE for data transmission after receiving the control signaling on the 6G control channel resource.

[0338] In this embodiment, if the UE supports the dynamic scheduling of the PDSCH of 5G and 6G, because the PDSCHs of the two may adopt different encoding modes, the UE needs to know what mode to use to interpret the PDSCH after interpreting the second control channel, so the time delay between the PDCCH and the PDSCH is increased, and therefore, by increasing the second delay duration, it can be ensured that the terminal has enough time to obtain the decoding mode of the data transmission scheduled by the second control channel after receiving the second control channel.

[0339] Optionally, the UE sends feedback information to the network side device based on a third delay duration, and the feedback information is used to indicate to the network side device whether the UE correctly receives the second transmission. The third delay duration is reported by the UE or configured by the network or predefined by a protocol. For example, the UE sends the feedback information to the network side device at a sixth time point, which is obtained based on a sum of the third delay duration and a seventh time point, and the seventh time point is a time at which the UE obtains the second transmission.

[0340] The above scheme of the embodiment of the application achieves the purpose that the terminal can use the resource of the Mth generation communication system to perform the data transmission of the Nth generation communication system, so that the Nth generation communication system can share the resource of the Mth generation communication system to perform the data transmission, thereby effectively improving the spectrum utilization efficiency.

[0344] In a case that the terminal monitors the first control channel on the first resource, performing the first transmission at a first time;

[0345] The first time is determined based on a second time and a first delay duration, the second time is a time when the terminal monitors the first control channel on the first resource, and the first delay duration is a delay duration for the first transmission which is configured by a network side device or reported by the terminal to the network side device.
