Description

Technical Field

[0001] The embodiments of the present application relate to the field of wireless communication, and in particular, to communication processing technologies for non-scheduled resources. Background Art

[0002] A wireless communication system includes a terminal-side device and an access network-side device serving the terminal-side device. According to the protocol layer division formulated by the 3rd generation partnership project (3GPP) organization, the terminal-side device and the access network-side device respectively include a physical (PHY) layer, a medium access control (MAC) layer, a radio link control (RLC) layer, a packet data convergence protocol (PDCP) layer, and a radio resource control (RRC) layer, etc.

[0003] The access network-side device can configure non-scheduling resources and the period of the non-scheduling resources for the terminal-side device through RRC messages of the RRC layer. The non-scheduling resources can include at least one of semi-persistent scheduling (SPS) resources and configured grant resources. Among them, SPS resources are used for downlink data transmission or uplink data transmission, and configured grant resources are used for uplink data transmission. The terminal-side device can use the non-scheduling resources to perform uplink data transmission or downlink data transmission with the access network-side device. Optionally, before performing uplink communication or downlink communication, the access network-side device indicates in the physical downlink control channel (PDCCH) of the physical layer that the non-scheduling resources are activated. The non-scheduling resources have the characteristic of "once allocated, used multiple times", and "non-scheduling" can also be referred to as "pre-scheduling", "scheduling-free" or "semi-static scheduling". After the uplink data transmission is completed or the downlink data transmission is completed, the non-scheduling resources can be reconfigured or released.

[0004] On the downlink, the terminal-side device uses the non-scheduling resources to attempt to decode downlink data in each period; on the uplink, the access network-side device uses the non-scheduling resources to attempt to decode uplink data in each period. However, there may not be downlink data or uplink data in each period, especially when each period is relatively small, resulting in invalid power consumption for decoding by the terminal-side device or the access network-side device. Summary of the Invention

[0005] An embodiment of the present application provides a communication processing method for non-scheduled resources, which is conducive to reducing ineffective power consumption.

[0006] In a first aspect of the embodiments of the present application, a communication processing method for non-scheduled resources executed by a terminal-side device is provided. Among them, the terminal-side device may be an independent terminal as a whole, or at least one chip in the terminal or a circuit system in the terminal that implements the communication processing method for non-scheduled resources.

[0007] In the communication processing method for non-scheduled resources provided in the first aspect, the terminal-side device receives a configuration of a first non-scheduled resource sent by an access network-side device, and the configuration of the first non-scheduled resource includes at least two periods of the first non-scheduled resource; the terminal-side device determines the period used by the terminal-side device for data transmission among the at least two periods, and performs data transmission with the access network-side device according to the determined period.

[0008] Applying the technical solution provided in the first aspect, by pre-configuring multiple periods of the same non-scheduled resource for the terminal-side device, the period used can be determined in a timely manner from the multiple pre-configured periods during the current data transmission. Compared with the situation where only one period is configured for the same non-scheduled resource, the technical solution provided in the first aspect increases the diversity of the current data transmission period selection, thus increasing the possibility of using a more appropriate period for the current data transmission, and thus is conducive to reducing the consumption of ineffective power.

[0009] In a first possible implementation manner of the first aspect, the terminal-side device may further receive a first piece of information sent by the access network-side device, and the first piece of information indicates the silent time of the first non-scheduled resource; wherein, the first non-scheduled resource is unavailable during the silent time. Through the solution provided in the first possible implementation manner of the first aspect, the terminal-side device can refrain from using the first non-scheduled resource according to the indication of the silent time, which can further reduce the power consumption of the terminal-side device.

[0010] In a second possible implementation manner of the first aspect, the configuration of the first non-scheduled resource includes an uplink configuration of the first non-scheduled resource and a downlink configuration of the first non-scheduled resource, and the at least two periods of the first non-scheduled resource include a period corresponding to the uplink configuration and a period corresponding to the downlink configuration. Through the technical solution provided in the second possible implementation manner of the first aspect, it is clear that the configuration of the first non-scheduled resource may include an uplink configuration and a downlink configuration. Further, the configuration of the first non-scheduled resource may be carried in the same message cell, so as to realize the simultaneous configuration of the uplink configuration and the downlink configuration.

[0011] In the third possible implementation manner of the first aspect, the terminal-side device may determine the period used by the terminal device for data transmission by receiving the second information sent by the access network-side device, where the second information indicates the period used by the terminal-side device for data transmission among the at least two periods. The technical solution provided by the third possible implementation manner of the first aspect further describes that the period used for the current data transmission is indicated by the access network-side device.

[0012] In the fourth possible implementation manner of the first aspect, the terminal-side device determines whether to enter a silent state based on the third information sent by the access network-side device; if at least one condition indicated by the third information is met, it enters the silent state and then performs data transmission with the access network-side device according to the determined period after the silent time ends. Wherein, the third information indicates at least one of the following conditions: the maximum number of times M of continuously monitoring no downlink data transmission on the first non-scheduled resource, and the maximum duration K of continuously monitoring no downlink data transmission on the first non-scheduled resource. The fourth possible implementation manner of the first aspect specifically defines the conditions for the terminal-side device to enter the silent state, so that the terminal-side device can reduce power consumption during the silent time.

[0013] In the fifth possible implementation manner of the first aspect, the terminal-side device may determine whether to perform data transmission based on the third information sent by the access network-side device. When at least one of the conditions indicated by the third information is met, the terminal-side device determines the period for data transmission among the at least two periods and performs the data transmission. The fourth possible implementation manner of the first aspect defines the conditions for the terminal-side device to perform data transmission with the access network-side device, so that the terminal-side device can perform data transmission with the access network-side device after the conditions indicated by the third information are met.

[0014] In the sixth possible implementation manner of the first aspect, the terminal-side device may receive the configurations of at least two non-scheduled resources sent by the access network-side device, and the configurations of the at least two non-scheduled resources include the configuration of the first non-scheduled resource. The sixth possible implementation manner of the first aspect specifically defines that the terminal-side device can receive the configurations of multiple non-scheduled resources, where the configuration of the first non-scheduled resource is one of the configurations of these multiple non-scheduled resources. Compared with the situation where the terminal-side device is configured with only one configuration of a non-scheduled resource, the technical solution provided by the sixth possible implementation manner of the first aspect increases the diversity of the selection of non-scheduled resource configurations in the current data transmission, thus increasing the possibility of using a more suitable configuration of non-scheduled resources in the current data transmission, which is conducive to reducing the consumption of ineffective power.

[0015] In the seventh possible implementation manner of the first aspect, the terminal-side device may receive fourth information sent by the access network-side device, where the fourth information is used to activate the configuration of the first non-scheduled resource from the configurations of at least two non-scheduled resources. The seventh possible implementation manner of the first aspect specifically defines that the access network-side device activates the configuration of the first non-scheduled resource used for the current data transmission for the terminal-side device from the configurations of multiple non-scheduled resources.

[0016] In the eighth possible implementation manner of the first aspect, the fourth information is further used to deactivate the configuration of a second non-scheduled resource from the configurations of the at least two non-scheduled resources, where the configuration of the second non-scheduled resource is used for the terminal-side device to perform data transmission before the configuration of the first non-scheduled resource is activated. The eighth possible implementation manner of the first aspect can implement the switching of the configuration of the second non-scheduled resource to the configuration of the first non-scheduled resource in the current data transmission.

[0017] In the ninth possible implementation manner of the first aspect, in the case where the fourth information only activates the configuration of the first non-scheduled resource from the configurations of the at least two non-scheduled resources, the configurations of all other non-scheduled resources or the configurations of other non-scheduled resources that meet a preset condition in the configurations of the at least two non-scheduled resources are deactivated, where the preset condition is set by the access network-side device. The ninth possible implementation manner of the first aspect specifically defines the mechanism of how to handle other non-scheduled resources when only the configuration of the first non-scheduled resource is activated in the configurations of at least two non-scheduled resources, so as to reduce the waste of other non-scheduled resources.

[0018] A second aspect of the present application provides a communication processing method for non-scheduled resources executed by an access network-side device. Among them, the access network-side device may be an independent base station, or at least one chip in the base station or a circuit system in the base station that implements the communication processing method for non-scheduled resources. For example, a distributed unit (DU) or a central unit (CU) of the base station.

[0019] In a communication processing method for non-scheduled resources provided in the second aspect, the access network-side device sends the configuration of a first non-scheduled resource to the terminal-side device, where the configuration of the first non-scheduled resource includes at least two periods of the first non-scheduled resource; the access network-side device determines the period used by the terminal-side device for data transmission among the at least two periods, and performs data transmission with the terminal-side device according to the determined period.

[0020] Applying the technical solution provided by the second aspect, the access network side device can determine the cycle used in the current data transmission in a timely manner from the multiple cycles of the same non-scheduled resource pre-configured for the terminal side device. Compared with the case where only one cycle is configured for the same non-scheduled resource, the technical solution provided by the first aspect increases the diversity of the current data transmission cycle selection, thus increasing the possibility of using a more appropriate cycle for the current data transmission, which is conducive to reducing the consumption of ineffective power.

[0021] In the first possible implementation manner of the second aspect, the access network side device sends the first information to the terminal side device, and the first information indicates the silent time of the first non-scheduled resource; wherein, the first non-scheduled resource is unavailable during the silent time. Through the solution provided by the first possible implementation manner of the second aspect, the terminal side device can refrain from using the first non-scheduled resource according to the indication of the silent time, which can further reduce the power consumption of the terminal side device.

[0022] In the second possible implementation manner of the second aspect, the configuration of the first non-scheduled resource includes the uplink configuration of the first non-scheduled resource and the downlink configuration of the first non-scheduled resource, and at least two cycles of the first non-scheduled resource include the cycle corresponding to the uplink configuration and the cycle corresponding to the downlink configuration. Through the technical solution provided by the second possible implementation manner of the second aspect, it is clear that the configuration of the first non-scheduled resource can include the uplink configuration and the downlink configuration. Further, the configuration of the first non-scheduled resource can be carried in the same message cell, so as to realize the simultaneous configuration of the uplink configuration and the downlink configuration.

[0023] In the third possible implementation manner of the second aspect, the access network side device sends the second information to the terminal side device, and the second information indicates the cycle used by the terminal side device for data transmission among the at least two cycles. The technical solution provided by the third possible implementation manner of the second aspect further describes that the cycle used in the current data transmission is indicated by the access network side device.

[0024] In the fourth possible implementation manner of the second aspect, the access network side device sends the third information to the terminal side device, and the third information indicates at least one of the following conditions: the maximum number of times M of continuous monitoring without downlink data transmission on the first non-scheduled resource, the maximum duration K of continuous monitoring without downlink data transmission on the first non-scheduled resource; the third information is used by the access network side device to perform data transmission with the terminal side device according to the determined cycle. The fourth possible implementation manner of the second aspect specifically clarifies the conditions for the access network side device to indicate data transmission to the terminal side device.

[0025] In the fifth possible implementation manner of the second aspect, the access network side device sends configurations of at least two non-scheduled resources to the terminal side device, and the configurations of the at least two non-scheduled resources include the configuration of the first non-scheduled resource. The fifth possible implementation manner of the second aspect specifically specifies that the terminal side device can receive configurations of multiple non-scheduled resources, where the configuration of the first non-scheduled resource is one of the configurations of the multiple non-scheduled resources. Compared with the situation where the terminal side device is configured with only one configuration of non-scheduled resources, the technical solution provided by the fifth possible implementation manner of the second aspect increases the diversity of the selection of non-scheduled resource configurations in the current data transmission. Therefore, it increases the possibility of using a more suitable configuration of non-scheduled resources in the current data transmission, which is beneficial to reducing the consumption of ineffective power.

[0026] In the sixth possible implementation manner of the second aspect, the access network side device further sends fourth information to the terminal side device, and the fourth information is used to activate the configuration of the first non-scheduled resource from the configurations of at least two non-scheduled resources. The sixth possible implementation manner of the second aspect specifically specifies that the access network side device activates the configuration of the first non-scheduled resource used in the current data transmission for the terminal side device from the configurations of multiple non-scheduled resources.

[0027] In the seventh possible implementation manner of the second aspect, the fourth information is further used to deactivate the configuration of the second non-scheduled resource from the configurations of the at least two non-scheduled resources, and the configuration of the second non-scheduled resource is used for the terminal side device to perform data transmission before the configuration of the first non-scheduled resource is activated. The seventh possible implementation manner of the second aspect can realize the switching from the configuration of the second non-scheduled resource to the configuration of the first non-scheduled resource in the current data transmission.

[0028] In the eighth possible implementation manner of the second aspect, in the case where the fourth information only activates the configuration of the first non-scheduled resource from the configurations of the at least two non-scheduled resources, the configurations of all other non-scheduled resources or the configurations of other non-scheduled resources that meet a preset condition in the configurations of the at least two non-scheduled resources are deactivated, where the preset condition is set by the access network side device. The eighth possible implementation manner of the second aspect specifically specifies the mechanism of how to handle other non-scheduled resources when only the configuration of the first non-scheduled resource is activated in the configurations of at least two non-scheduled resources, thereby reducing the waste of other non-scheduled resources.

[0041] Figure 1 The wireless communication system shown includes an access network side device and a terminal side device, and optionally further includes a core network side device. Among them, the access network side device can be various transmission reception points (TRPs) such as a base station, a wireless local area network access point, etc., providing access services under authorized spectrum or access services under unlicensed spectrum for the terminal side device. The access network side device is connected to the core network side device by wire or wirelessly. The terminal side device includes a user equipment (UE), which is a device that provides voice and / or data connectivity to users. For example, it can be a handheld device with a wireless connection function, a vehicle-mounted device, etc. Common terminal side devices include, for example: mobile phones, tablet computers, laptop computers, palmtop computers, mobile internet devices (MIDs), wearable devices such as smart watches, smart bracelets, pedometers, etc. The terminal side device can be provided with communication services by one access network side device, or can also use dual-connection technology to be provided with communication services by at least two access network side devices simultaneously.

[0042] The terminal-side device and the access network-side device respectively transmit uplink data and downlink data on the air interface according to the protocol layers on the uplink and downlink. Among them, the access network-side device can be an independent device or can be split into different devices according to the protocol layers. For example, after the access network-side device is split according to the protocol layers, the access network-side device may include a control unit (CU) and at least one distributed unit (DU). The CU is used to implement the functions of the PDCP layer, RRC layer and the protocol layers above it of the access network-side device; the DU is used to implement the functions of the RLC layer, MAC layer and PHY layer of the access network-side device. Those skilled in the art can understand that: in the following various implementation manners, the functions of the access network-side device in the PDCP layer, RRC layer or the protocol layers above it can be executed by the CU; the functions of the access network-side device in the RLC layer, MAC layer or PHY layer are executed by the at least one DU.

[0043] Figure 1 The wireless communication system shown can be a wireless communication system such as a New Radio (NR) system (also known as a 5G system), an LTE (long term evolution) system, and an advanced long term evolution (LTE-A) system.

[0044] In various embodiments of the present application, from a physical implementation perspective, the access network-side device can be a base station, a wireless local area network access point itself, or a chip or circuit system in the base station or the wireless local area network access point; the terminal-side device can be a user equipment itself, or a chip or circuit system in the user equipment.

[0045] In various embodiments of the present application, the data transmission between the terminal-side device and the access network-side device is uplink data transmission or downlink data transmission.

[0046] In various embodiments of the present application, non-scheduled resources are generally used for the transmission of periodic data with a substantially constant size. For example, industrial automation data with a period of 1 ms, and voice over internet protocol (VOIP) data with a period of 20 ms and a packet size of about 100 bytes, etc. Scheduled resources are resources dynamically allocated by the access network side device in response to a resource scheduling request from the terminal side device (e.g., a scheduling request transmitted through a random access preamble in a random access process or a physical uplink control channel). In contrast to the scheduled resources, non-scheduled resources are resources pre-allocated by the access network side device for the terminal side device without a resource scheduling request from the terminal side, such as semi-persistent scheduling (SPS) resources and configured grant (CG) resources, etc. SPS resources are used for downlink data transmission or uplink data transmission, while CG resources are mainly used for uplink data transmission, but it does not exclude that CG resources may also be used for downlink data transmission.

[0047] For the transmission of periodic data, generally, the access network side device configures at least one period for a non-scheduled resource, and the terminal side device and the access network side device can use a period that is the same as or close to the period of the data to be transmitted in at least one configured period for uplink data transmission or downlink data transmission. By making a one-time allocation of non-scheduled resources for the terminal side device, before the non-scheduled resources are reconfigured or released, the terminal side device can use the non-scheduled resources multiple times in multiple periods without the access network side device making dynamic resource allocation through the PDCCH in each period with data transmission, which can save signaling overhead on the PDCCH. However, not every period has data transmission, but the terminal side device or the access network side device still tries to decode in periods without data transmission, especially when these periods are small, resulting in more invalid power consumption for decoding by the terminal side device or the access network side device.

[0048] In view of the above technical problems, the first embodiment of the present application provides a communication processing method for non-scheduled resources. As Figure 2 shown in the system interaction schematic diagram, it includes the following content.

[0049] 201, the access network side device sends a configuration of the first non-scheduled resource to the terminal side device, and the configuration of the first non-scheduled resource includes at least two periods of the first non-scheduled resource.

[0050] In 201, at least two periods of the first non-scheduled resource are different, and can be selected by the access network side device from multiple candidate periods of the non-scheduled resource and configured for the terminal side device. Wherein, the unit of one period can be milliseconds, microseconds, nanoseconds, or a positive integer multiple of one transmission time unit. One transmission time unit can be at least one time domain symbol, at least one NR time slot, at least one LTE or NR sub-frame, at least one NR sub-slot, at least one NR span, or at least one frame, etc. The duration of one period can be infinite. When the period of the first non-scheduled resource is configured to be infinite, the first non-scheduled resource can be regarded as an aperiodic resource in this special case.

[0051] The multiple candidate periods can be pre-stored in the terminal side device or the access network side device in the form of a list. The type of this list is optionally represented by an enumerated type in the Abstract Syntax Notation One (ASN.1) language, such as ENUMERATED{period 1, period 2, …}. This enumerated type represents the list {period 1, period 2, …} selected from the list {…}. Among them, the values of the elements in the list can be different. When the measurement unit of the values of the elements in the list uses absolute time, the above list can be expressed as {period 1 = 1 millisecond, period 2 = 10 milliseconds, …}. When the measurement unit of the values of the elements in the list uses relative time, the above list can be expressed as a combination of {1, 2, …} and a default scaling factor (such as 10), then period 1 = 1 * 10 milliseconds, period 2 = 2 * 10 milliseconds. When the measurement unit of the values of the elements in the list uses relative time, the above list can also be expressed as {period 1 (milliseconds), scaling factor 1, scaling factor 2, …, scaling factor N}, then period 2 is equal to period 1 multiplied by scaling factor 1, period 3 is equal to period 1 multiplied by scaling factor 2, and period N - 1 is equal to period 1 multiplied by scaling factor N.

[0052] The access network side device can configure at least two periods of the first non-scheduled resource for the terminal side device through an RRC message. This RRC message can be an RRC connection reconfiguration message during the RRC connection reconfiguration process, an RRC connection establishment message during the RRC connection establishment process, an RRC connection recovery message during the RRC connection recovery process, or an RRC connection release message during the RRC connection release process.

[0053] Optionally, the RRC message may also configure hybrid automatic repeat request (HARQ) parameters (e.g., HARQ process number) and modulation coding scheme (MCS) for data transmission on the first non-scheduled resource, etc.

[0054] When the first non-scheduled resource is a type 1 CG resource specified by the 3GPP standard, the RRC message may also configure the time-frequency position of the first non-scheduled resource.

[0055] When the first non-scheduled resource is an SPS resource or a type 2 CG resource specified by the 3GPP standard, the access network device indicates through the PDCCH that the configuration of the non-scheduled resource is activated and indicates the time-frequency position of the first non-scheduled resource, and the terminal device obtains the time-frequency position of the first non-scheduled resource according to the indication of the PDCCH, as Figure 3 shown in the resource allocation schematic diagram, and performs data transmission with the access network device periodically at the time-frequency position of the first non-scheduled resource.

[0056] The first non-scheduled resource may be at least one of an uplink resource and a downlink resource. Optionally, the configuration of the first non-scheduled resource includes the uplink configuration of the first non-scheduled resource and the downlink configuration of the first non-scheduled resource, and at least two periods of the first non-scheduled resource include a period corresponding to the uplink configuration and a period corresponding to the downlink configuration.

[0057] Among them, the uplink configuration of the non-scheduled resource includes the starting position of the uplink resource and the starting position of the downlink resource. Among them, the starting position of the time-domain resource can be represented by a frame number and a time-domain offset. The starting position of the frequency-domain resource can be represented by a carrier number, a bandwidth part (BWP) index, and a resource block (RB) index.

[0058] 202, the terminal device determines the period used by the terminal device for data transmission among at least two periods of the first non-scheduled resource.

[0059] 203, the terminal device performs data transmission with the access network device according to the determined period.

[0060] Before 203, the access network side device may also send first information to the terminal side device, where the first information indicates the silent time of the first non-scheduled resource, and within the silent time, the first non-scheduled resource is unavailable. The silent time may be a periodic time period or an aperiodic time period; among them, the periodic time period may be a discontinuous reception (DRX) cycle configured when the terminal side device is in the RRC connected state.

[0061] The unavailability of the first non-scheduled resource may be that the first non-scheduled resource is in a deactivated state, a cleared state or a released state.

[0062] The deactivated state means that the current first non-scheduled resource cannot be used, but the first non-scheduled resource can be reserved or cleared, and other RRC configuration parameters related to the first non-scheduled resource are retained, such as the HARQ parameters of the first non-scheduled resource, the period configured for the first non-scheduled resource, etc.; if the terminal side device clears the first non-scheduled resource, it will not use the first non-scheduled resource for data transmission until the access network side device indicates that the first non-scheduled resource is activated.

[0063] The cleared state means that the first non-scheduled resource itself is cleared, but other RRC configuration parameters related to the first non-scheduled resource (such as HARQ parameters and the configured period) are retained. After the access network side device indicates that the first non-scheduled resource is activated, the terminal side device can use the first non-scheduled resource for data transmission.

[0064] The released state means that the terminal side device clears all configurations of the first non-scheduled resource, including other RRC configuration parameters related to the first non-scheduled resource (such as HARQ parameters and the configured period) and the first non-scheduled resource itself. The terminal side device will use the first non-scheduled resource for data transmission only after receiving the RRC configuration parameters (HARQ parameters and period) sent by the access network side device and the re-allocated first non-scheduled resource itself.

[0065] Specifically, the first information may indicate the starting time-domain position of the silent time, and the terminal-side device determines that the first non-scheduled resource within a duration starting from this starting time-domain position (the duration may be indicated by the access network-side device through the first information or may be predefined) is unavailable. After the silent time ends, the terminal-side device can perform data transmission with the access network-side device according to the methods in 201-203 described above. Optionally, the silent time indicated by the first information can be stored in the list of multiple candidate periods in 201, such as {period 1, period 2,..., silent time}. The access network-side device can select the silent time from the stored list and send it to the terminal-side device.

[0066] In 202, the manner in which the terminal-side device determines the period used for data transmission can be: receiving the second information sent by the access network-side device, and this second information indicates the period used by the terminal-side device for data transmission from at least two configured periods. The terminal-side device determines the period used for data transmission according to the second information. This situation can be applicable to the scenario where the terminal-side device uses the first non-scheduled resource for downlink data transmission or uplink data transmission. The second information can be carried in the same message cell as the configuration of the first non-scheduled resource or in different message cells. The second information can also be included as part of the configuration of the first non-scheduled resource and be contained in the configuration of the first non-scheduled resource.

[0067] The second information can be downlink control information (DCI) carried on the PDCCH, a MAC control element, an RLC layer or PDCP layer message. The access network-side device can also indicate the resource position (such as the time-domain position) where the first non-scheduled resource becomes effective in the period used for data transmission.

[0068] For example, in the case where the second information is DCI, the access network-side device can indicate the offset relative to the time-domain position when receiving the DCI, and the terminal-side device can determine from which time-domain position the first non-scheduled resource becomes effective in each period for data transmission according to this offset.

[0069] For example, in the case where the second information is carried in a MAC control element, an RLC layer or PDCP layer message, the access network-side device can indicate the offset relative to a certain reference time-domain position, and the terminal-side device can determine from which time-domain position the first non-scheduled resource becomes effective in each period for data transmission according to this offset. Among them, this reference time-domain position can be the time-domain starting position of the first non-scheduled resource in each period.

[0070] If the period indicated by the second information is different from the period used by the terminal-side device for ongoing data transmission or for preparing to perform data transmission, the terminal-side device may switch to the period indicated by the second information for data transmission. Optionally, the terminal-side device may clear or release the non-scheduled resources corresponding to the period used before the switch. Optionally, the period indicated by the second information has a validity period, and the terminal-side device uses the period indicated by the second information for data transmission within the validity period, and after the validity period expires, uses the period used before the switch for data transmission. This validity period may be from the start to the end of the data transmission after the switch, as Figure 4 shown. This validity period may be configured by the access network-side device for the terminal-side device.

[0071] For example, the terminal-side device and the access network-side device are using period 1 for VOIP data transmission. When the access network-side device has periodic Ultra-Reliable and Low Latency Communications (URLLC) data to send to the terminal-side device, the access network-side device sends the second information to the terminal-side device. The terminal-side device switches to period 2 (less than period 1) according to the second information to receive the URLLC data, and after the URLLC data transmission is completed, resumes VOIP data transmission using period 1.

[0072] In 202, the manner in which the terminal-side device determines the period used for data transmission can also be as follows: The terminal-side device independently determines the period used for data transmission from at least two configured periods without the indication of the access network-side device. This situation applies to the scenario where the terminal-side device uses the first non-scheduled resource for uplink or downlink data transmission. For example, the terminal-side device can default that the first configured period among the at least two configured periods is the period for uplink data transmission, and the second period is the period for downlink data transmission. Another example is that the terminal-side device can obtain third information. The third information can be sent by the access network-side device to the terminal-side device or be predefined by the standard. The third information indicates at least one of the following conditions: the maximum number of times M of continuously monitoring no downlink data transmission on the first non-scheduled resource, or the maximum duration K of continuously monitoring no downlink data transmission on the first non-scheduled resource; the terminal-side device determines that when at least one of the conditions is met, the terminal-side device independently determines the period used for data transmission among the at least two periods. For this implementation, the terminal-side device can also notify the access network-side device of the period used for the current data transmission independently determined by the terminal-side device to ensure the consistency of understanding of the period for the current data transmission between the terminal-side device and the access network-side device.

[0073] In 203, the terminal-side device can obtain third information. The third information can be sent by the access network-side device to the terminal-side device or be predefined by the standard. The third information indicates at least one of the following conditions: the maximum number of times M of continuously monitoring no downlink data transmission on the first non-scheduled resource, or the maximum duration K of continuously monitoring no downlink data transmission on the first non-scheduled resource. When the terminal-side device determines that at least one of the conditions indicated by the third information is met, the terminal-side device enters a silent state, and after the silent time ends (or the non-silent time), the terminal-side device performs data transmission with the access network-side device according to the determined period. The silent time can be the time indicated by the aforementioned first information, and the determined period can be the period indicated by the aforementioned second information or the period independently determined by the terminal-side device according to the aforementioned manner.

[0074] Applying the technical solution provided by the first embodiment, a non-scheduled resource is configured with at least two periods, and the terminal-side device and the access network-side device can adjust the required period according to the actual requirements of data transmission during data transmission. The technical solution provided by the first embodiment, the configuration of multiple periods of the same non-scheduled resource is beneficial to adopting a shorter period during the period of intensive data transmission (such as URLLC data transmission), and adopting a longer period during the period of sparse data transmission (such as VOIP data transmission), so as to achieve the compromise goal of reducing the ineffective power consumption of the terminal-side device and meeting the data transmission requirements.

[0075] The second embodiment of the present application provides a communication processing method for non-scheduled resources, as Figure 5 shown. The method provided by the second embodiment can be based on the communication processing method of non-scheduled resources in the first embodiment.

[0076] S501, the terminal-side device receives the configuration of at least two non-scheduled resources sent by the access network-side device.

[0077] The configuration of the at least two non-scheduled resources includes the period of each non-scheduled resource. The configurations of different non-scheduled resources can be different, which are represented by different configuration identifiers, and specifically can be reflected in different resource positions, different periods or different HARQ parameters of different non-scheduled resources.

[0078] For the convenience of description and unification of terms with the first embodiment, without loss of generality, any one of the at least two non-scheduled resources is the first non-scheduled resource. The configuration of the first non-scheduled resource includes at least one period of the first non-scheduled resource, HARQ parameters (such as HARQ process number) and MCS, etc. When the first embodiment is combined with the second embodiment, the at least one period of the first non-scheduled resource is at least two periods.

[0079] S502, the access network-side device sends the fourth information to the terminal-side device, and the fourth information is used to activate the configuration of the first non-scheduled resource from the configuration of the at least two non-scheduled resources.

[0080] In 502, the fourth information may carry the index of the configuration of the first non-scheduled resource. Among them, the configuration of the first non-scheduled resource may be unused after being configured by S501 and is activated for the first time by the fourth information; the configuration of the first non-scheduled resource may also be cleared or released by the terminal-side device after being configured by S501, and then re-activated by the fourth information; the configuration of the first non-scheduled resource may also be configured and used by S501, that is, the first non-scheduled resource is currently active, and is re-activated by the fourth information.

[0081] Optionally, the method further includes, as Figure 6 shown: The terminal-side device uses the configuration of the second non-scheduled resource in the configuration of the at least two non-scheduled resources for data transmission before the configuration of the first non-scheduled resource is activated. During the current data transmission, the fourth information can activate the configuration of the first non-scheduled resource, so that the terminal-side device can use the configuration of the first non-scheduled resource for the current data transmission. When activating the configuration of the first non-scheduled resource, the fourth information can also indicate the deactivation of the configuration of the second non-scheduled resource, so that the terminal-side device stops using the configuration of the second non-scheduled resource for data transmission when using the configuration of the first non-scheduled resource for the current data transmission.

[0082] Optionally, if the fourth information only indicates the activation of the configuration of the first non-scheduled resource, the terminal-side device determines that the configurations of all other non-scheduled resources or the configurations of other non-scheduled resources that meet a preset condition in the configuration of the at least two non-scheduled resources are deactivated, where the preset condition is set by the access network device. The preset condition is the configuration of other non-scheduled resources that has an association relationship with the configuration of the first non-scheduled resource. This association relationship can be set by the access network side device and notified to the terminal-side device. This association relationship can be set according to the same data type. For example, the access network side device sets the configurations of multiple non-scheduled resources associated with URLLC data and notifies the terminal-side device. If the fourth information only activates the configuration of the first non-scheduled resource among these multiple non-scheduled resource configurations, since the other non-scheduled resources among these multiple non-scheduled resource configurations are also associated with the URLLC data, the terminal-side device determines that the other non-scheduled resources associated with the URLLC data are deactivated. After the configuration of the first non-scheduled resource is activated, the terminal-side device confirms that the current data transmission using the configuration of the first non-scheduled resource is a new data transmission.

[0083] Among them, the fourth information can be a physical layer DCI or a MAC layer MAC control element.

[0084] Applying the technical solution provided by the second embodiment, the terminal-side device can be configured with at least two configurations of non-scheduled resources, and the terminal-side device and the access network-side device can adjust the required configuration according to the actual requirements of data transmission during data transmission. In the technical solution provided by the second embodiment, the configurations of different types of non-scheduled resources are further beneficial to adopting a configuration with an average shorter period during periods of intensive data transmission (such as URLLC data transmission), and adopting a configuration with an average longer period during periods of sparse data transmission (such as VOIP data transmission), so as to achieve a further compromise between reducing the ineffective power consumption of the terminal-side device and meeting the data transmission requirements.
