The scenario of the embodiment of the present invention is described below by way of example, but the present invention is not limited thereto.

1 is a schematic diagram of a communication system according to an embodiment of the present invention. The terminal device and the network device are exemplarily illustrated. As shown in FIG. 1, the communication system 100 may include a network device 101 and a terminal device 102. For the sake of simplicity, FIG. 1 is only described by taking one terminal device and one network device as an example, but the embodiment of the present invention is not limited thereto.

In the embodiment of the present invention, an existing service or a service that can be implemented in the future can be performed between the network device 101 and the terminal device 102. For example, these services may include, but are not limited to, enhanced mobile broadband (eMBB), massive machine type communication (mMTC), and ultra-reliable low-latency communication (URLLC, Ultra-Reliable and Low-Latency Communication), and so on.

The embodiment of the present invention will be described below by taking the NR system as an example; however, the present invention is not limited thereto, and can be applied to any system or scenario in which similar problems exist. In addition, the information receiving device or the receiving device of the present invention may be a terminal device, and the information transmitting device or the transmitting device may be a network device, but the present invention is not limited thereto; for example, the information receiving device or the receiving device may also be a network device. The information transmitting device or the transmitting device may be a terminal device.

The following describes the embodiment of the present invention by taking the URLLC service as an example. However, the present invention is not limited thereto, and can be applied to any other service with high transmission requirements, such as a voice service or a real-time online game service, which has similar problems.

URLLC transmissions have extremely high requirements for transmission reliability and transmission delay. For example, it is required that the data arrives at the layer 2/layer 3 buffer of the transmitting device, and until the data is correctly demodulated and stored in the layer 2/layer 3 buffer of the receiving device, the transmission delay cannot exceed 1 ms. At the same time, the transmission needs to meet the correct rate of 99.999%, that is, only one transmission failure (timeout or transmission error) can occur for every 100,000 packets transmitted.

In order to achieve the above high requirements for URLLC transmission and improve the utilization efficiency of time-frequency resources, URLLC transmission requires a more accurate transmission configuration than conventional eMBB transmission. For example, the time-frequency resource used by the Grant free UL transmission mode that can be used to carry the URLLC service requires the network device to configure the terminal device through high-layer RRC signaling. For another example, the modulation and coding scheme used for the physical layer transmission for carrying the URLLC service may also require the network device to configure the terminal device through the high layer RRC signaling. In order to avoid subsequent physical layer transmission errors due to errors in the configuration process, the reliability of the physical layer transmission configuration should be greater than the reliability required for URLLC transmission.

In the existing physical layer transmission configuration scheme/technology mainly serving the traditional eMBB service, the network device and/or the terminal device usually implement/set the time point of the last physical time-frequency resource where the high-level signaling is located as a reference point. The new configuration carried by the signaling does not take into account the acknowledgment of the reliability of the higher layer signaling carrying the new configuration. This may result in unreliable high-level signaling carrying new configurations. If the existing physical layer transmission configuration scheme/technology is adopted, such unreliability may reduce the reliability of the physical layer transmission of the URLLC service and/or increase the delay of the physical layer transmission of the URLLC service, because the physical layer transmission of the URLLC service is a high-level letter. Make the configuration of the bearer based on the configuration. How to improve the reliability of the physical layer transmission configuration is an urgent problem to be solved.

In addition, in the existing physical layer transmission configuration scheme/technology, the terminal device enables the RRC configuration (for example, the new configuration included in the configuration) when transmitting the “RRC Configuration Complete” message to the base station device without confirming the “RRC configuration”. Complete the reliability of the message. If the transmission of the "RRC Configuration Complete" message is incorrect, it may cause the terminal device to have enabled the new configuration and the network device has not enabled the new configuration. The terminal device and the network device adopt an inconsistent transmission configuration. The impact of this inconsistency on the traditional eMBB service is not obvious, because the delay requirement of the traditional eMBB service is greater than or equal to the transmission time of the configuration completion message.

However, the delay requirement of the URLLC service is significantly smaller than the transmission time of the configuration completion message. Therefore, the inconsistency of the transmission configuration may cause the URLLC service service carried by the physical layer transmission corresponding to the configuration to fail, that is, the 1 ms delay cannot be satisfied. The required 99.999% reliability. Therefore, how to improve the reliability of the physical layer transmission configuration effective time is an urgent problem to be solved.

Example 1

An embodiment of the present invention is to use the existing Radio Link Control (RLC) Automatic Repeat ReQuest (ARQ) mechanism to confirm the high-level configuration signaling and/or configuration completion message. Transfer correctly. The problem with the RLC layer ARQ mechanism is that it uses the polling method to transmit/receive ACK or NACK signals, so the timeliness cannot be guaranteed. In the existing mechanism, for example, the coded modulation scheme of the physical layer transmission may be configured by the high layer signaling, and the timeliness cannot guarantee that the configured physical layer transmission scheme may not match the physical channel, thereby invalidating the configuration or performing poorly. Another solution is to utilize the existing HARQ (Hybrid Automatic Repeat reQuest) mechanism. The physical layer HARQ mechanism has at least the following problem: the reliability is low, for example, when the NACK signal is sent, the probability of erroneously becoming an ACK is about 1%; or, in the protocol architecture of the existing mobile communication system, the physical layer cannot be established. The association between the ACK/NACK signal and the high layer signaling, for example, the physical layer cannot confirm whether a high level signaling is included in one transport block.

Therefore, in order to solve at least one of the above problems, an embodiment of the present invention provides a method for receiving and transmitting information. 2 is a schematic diagram of an information receiving and transmitting method according to an embodiment of the present invention, showing a situation on the terminal device side. As shown in Figure 2, the method includes:

Step 201: The terminal device receives high layer signaling sent by the network device, where the high layer signaling includes at least configuration information related to the terminal device receiving or transmitting a physical layer signal;

Step 202: The terminal device receives, by the network device, at least an acknowledgment message for confirming the configuration information, or sends, to the network device, at least an acknowledgment message for confirming the configuration information, where the acknowledgment message is sent. It is carried by medium access control signaling or physical layer signaling.

For example, the high layer signaling may be Radio Resource Control (RRC) signaling or Media Access Control (MAC) signaling.

In this embodiment, the acknowledgement message is carried by the medium access control signaling or the physical layer signaling. For example, the medium access control signaling or the physical layer signaling may only carry the acknowledgement message, or may be The medium access control signaling or physical layer signaling carries other messages and the like in addition to carrying the acknowledgement message. The confirmation message may be, for example, a message, or may be information, or may be a signal carrying information or the like. The medium access control signaling may be, for example, bit information, or may be byte information or the like.

In this embodiment, the acknowledgement message may be carried by the MAC signaling. In this way, both delay and reliability can be considered. Compared with the ACK/NACK signal that sends the RLC layer by using the polling mechanism, the acknowledgement message can be quickly handed over to the physical layer for transmission after the MAC layer is generated; compared to the existing physical layer ACK/NACK signal, the MAC layer When the message is transmitted at the physical layer, the reliability can be ensured through the physical layer retransmission mechanism.

In this embodiment, the acknowledgement message may also be carried by physical layer signaling. In this way, the transmission delay of the acknowledgment message can be further reduced, thereby enhancing the validity of the configuration information corresponding to the acknowledgment message and improving the transmission efficiency. The acknowledgement message carried by the physical layer control signaling may be sent, for example, through a physical layer control channel or a physical layer data channel, or may be a physical layer ACK/NACK signal with enhanced reliability, or the physical The physical signal corresponding to the layer control signaling itself may also be the acknowledgement message or the like.

The confirmation message in step 202 is related to the configuration information in step 201. After receiving the high layer signaling that carries the configuration information, the terminal device sends or receives MAC signaling or physical layer signaling that carries the acknowledgement message, and may be used to confirm that the configuration information is correctly received, and/or , confirm the effective time of some or all of the configuration information. In other words, the effective time of some or all of the configuration information is at least related to the sending or receiving time of the MAC signaling or physical layer signaling. For example, the initial effective time unit of some or all of the configuration information is related to at least the time unit of sending or receiving the MAC signaling or physical layer signaling.

In an implementation method, the terminal device sends or receives MAC signaling or physical layer signaling that carries the acknowledgement message, and may be used to confirm the effective time of some or all of the configuration information. The terminal device starts or transmits a physical signal by using part or all of the configuration information that is valid, starting from an effective time of part or all of the configuration information. And/or, the network device starts to send or receive a physical signal by using part or all of the configuration information that is valid, starting from an effective time of part or all of the configuration information.

It should be noted that the foregoing “at least for” may include: the confirmation message may be used to confirm or activate other RRC configuration information or RRC signaling, in addition to confirming the foregoing RRC configuration information and/or confirming the configuration completion message.

It is to be noted that the above-mentioned FIGS. 3 to 6 only schematically illustrate the embodiment of the present invention, but the present invention is not limited thereto. For example, the order of execution between the various steps can be appropriately adjusted, and other steps can be added or some of the steps can be reduced. Those skilled in the art can appropriately adapt according to the above, and are not limited to the above description of FIGS. 3 to 6.

In addition, the terminal device may further receive a physical downlink control channel (PDCCH) that is sent by the network device, where the PDCCH is used to schedule a physical downlink data channel where the high layer signaling is located, for example, a physical downlink shared channel (PDSCH, Physical Downlink Shared Channel). The transmission of the PDCCH may be included, for example, in step 301, step 401, step 501, and step 601.

In this embodiment, the configuration information related to the receiving or transmitting the physical layer signal of the terminal device included in the high layer signaling may include at least one of the following information: unscheduled resource configuration information (including, for example, a Type) I Grant free resource configuration and Type II Grant free resource configuration), downlink semi-persistent scheduling (SPS, Semi-Persistent Scheduling) resource configuration information, non-slot-based physical downlink control channel search space (Non-slot based) The search space of the PDCCH, the candidate time-frequency resource of the physical uplink control channel (PUCCH), the transmit beam indication, the receive beam indication, the high-reliability transmission configuration information, the low-latency transmission configuration information, and the like.

It should be noted that the foregoing “at least for” may include: the acknowledgement message may be used as a function other than the acknowledgement, and the acknowledgement message may be used to confirm or activate other RRC configuration information in addition to the foregoing RRC configuration information.

In an embodiment, before step 201, the method may further include:

Step 200: The terminal device receives first indication information that is sent by the network device, where the first indication information is used to indicate that the terminal device receives or sends the identifier for receiving the high layer signaling. MAC signaling of the configuration information or the physical layer signaling.

The first indication information may be carried by the second higher layer signaling.

The second high layer signaling carrying the first indication information may be the same as the high layer signaling (for example, referred to as the first high layer signaling) carrying the configuration information in step 201. For example, the high-level signaling of the bearer configuration information in step 201 carries the first indication information, thereby indicating that the terminal device receives or sends the high-level signaling after receiving the bearer configuration information. Confirming MAC signaling of the configuration information or the physical layer signaling.

For example, the RRC signaling is used to carry configuration information related to the physical layer transmission, and the first indication information is also included in the RRC signaling, where the first indication information is only related to the physical layer transmission configuration indicated at the time. effective. The first indication information is used to indicate that the parameter about the physical layer transmission carried by the RRC signaling or the configuration is (and/or not) valid when the terminal device receives a subsequent MAC signaling or after.

The second high layer signaling carrying the first indication information may also be different from the high layer signaling (for example, referred to as the first high layer signaling) carrying the configuration information in step 201. For example, before the step 201, the first indication information is carried by the second high layer signaling, so that the terminal device receives or sends the acknowledgement to the acknowledgement after receiving the high layer signaling of the bearer configuration information. MAC signaling of the configuration information or the physical layer signaling.

The first indication information is used to indicate that the configuration information of the high layer signaling bearer is valid when the MAC signaling or the physical layer signaling is received or sent.

For example, before the first high layer signaling, the network device may further receive second high layer signaling (eg, RRC signaling) including the first indication information. The first indication information included in the RRC signaling is used to indicate a parameter or configuration about the physical layer transmission carried by the high layer signaling of the bearer configuration information (for example, referred to as the first high layer signaling) in a subsequent period of time. Is valid when the terminal device receives or sends a subsequent MAC signaling.

For example, "subsequent periods" may include the following:

It can be until the next time there is a new indication (either explicit or implicit). The new indication may be an explicit indication, for example, indicating that the new indication information is used in the subsequent RRC signaling instead of the original indication; the new indication may also be an implicit indication, for example, the original bearer indication When the RRC IE of the information is retransmitted, the indication information is not included, and the terminal device removes the setting corresponding to the original indication information when receiving the retransmitted RRC IE.

Alternatively, the validity period may be agreed in advance, and the indication information is valid for the validity period.

Alternatively, the RRC signaling including the first indication information may further include information indicating a location of the “period” on a time axis; the location of the “period” on the time axis may pass the time period. The duration and the start position indication can also be indicated by the start and end positions of the period.

In an embodiment, the high layer signaling may further include second indication information, where the second indication information is used to indicate a system frame number (SFN, System Frame Number) where the configuration information starts to take effect. Or subframe number and/or slot number.

It should be noted that the above first indication information and second indication information may be included in an information element (IE, Information Element) in RRC signaling, such as an optional IE or a mandatory IE; however, the present invention is not limited thereto.

In this embodiment, the MAC signaling or the physical layer signaling may also be used to confirm the effective time of the configuration information.

In an embodiment, the terminal device may determine a type of the PDCCH that schedules the high layer signaling; and determine an effective time of the configuration information according to the type of the PDCCH.

For example, a PDCCH type may be stored in advance in the terminal device. In the case that the high layer signaling is scheduled by the first type of PDCCH, the configuration information is determined to be valid when the high layer signaling is received or after; when the high layer signaling is scheduled by the second type of PDCCH The configuration information is determined to be valid when or after the MAC signaling or physical layer signaling is received or transmitted.

In an embodiment, the terminal device may determine a type of a MAC header that directs a MAC packet in which the higher layer signaling is located; and determine an effective time of the configuration information according to a type of the MAC header.

For example, the type of the MAC header may be stored in advance in the terminal device. In a case that the MAC packet where the high layer signaling is located is guided by the first type of MAC header, the configuration information is determined to be valid when the high layer signaling is received or after; the MAC packet where the high layer signaling is located In the case of being guided by the second type of MAC header, the configuration information is determined to be valid when or after the MAC signaling or physical layer signaling is received or transmitted.

In an embodiment, the terminal device may determine a type of an RLC header that directs the RLC packet in which the higher layer signaling is located; and determine an effective time of the configuration information according to the type of the RLC header.

For example, the type of the RLC header may be stored in advance in the terminal device. In a case that the RLC packet in which the high layer signaling is located is guided by the first type of RLC header, the configuration information is determined to be effective when the high layer signaling is received or after; the RLC packet where the high layer signaling is located In the case of being guided by the second type of RLC header, the configuration information is determined to be valid when or after the MAC signaling or physical layer signaling is received or transmitted.

It is to be noted that the above embodiments are merely illustrative of the embodiments of the present invention, but the present invention is not limited thereto, and appropriate modifications may be made based on the above respective embodiments. For example, each of the above embodiments may be used alone, or one or more of the above respective embodiments may be combined.

According to the foregoing embodiment, after receiving the configuration information related to receiving or transmitting the physical layer signal, the terminal device receives or sends at least MAC signaling or physical layer signaling for confirming the configuration information. . Thereby, the transmission reliability of the transmission configuration itself is improved and/or the configuration effective blur period during configuration is reduced.

Example 2

In order to improve the reliability of the physical layer transmission configuration effective time, one method of the embodiment of the present invention is that the network identification and the terminal device determine the same relative time point, and use the relative time point as a reference point to confirm the effective time of the high-level configuration information. Another method is that the network identification and the terminal device determine the same absolute time point, and use the absolute time point as a reference point to confirm the effective time of the high-level configuration information. There is more standardization work required to implement the former method, but more flexibility can be provided, for example, in the first embodiment of the present invention; the standardization work described in the latter method is less, and the existing existing method can be reused more. Standard mechanisms/methods/definitions, etc., but with respect to the former method, there may be a greater delay between the configuration information and the effective time in the latter method. In the standardization process, one of two methods can be selected according to the priority of the URLLC topic and the standardization time available for the subject.

Therefore, in order to solve at least one of the above problems, an embodiment of the present invention provides a method for receiving and transmitting information. FIG. 7 is a schematic diagram of an information receiving and transmitting method according to an embodiment of the present invention, showing a situation on the terminal device side. As shown in FIG. 7, the method includes:

Step 701: The terminal device receives the high layer signaling sent by the network device, where the high layer signaling includes at least configuration information related to the terminal device receiving or transmitting the physical layer signal;

Step 702: The terminal device determines an initial effective time of the configuration information, where the initial effective time is at least related to a period in which the high layer signaling is received.

Therefore, in this embodiment, since the initial effective time of the configuration information is related to at least the period in which the terminal device receives the high layer signaling, the accuracy of the physical layer transmission configuration effective time point can be improved and the accuracy is improved. Reliability, or in other words, can improve the transmission reliability of the transmission configuration itself and/or reduce the configuration effective blur period during configuration.

In this embodiment, the start of the initial effective time may be, for example, part or all of the configuration information.

In an embodiment, the terminal device receives the reception that may be the layer of the higher layer signaling at the terminal device corresponding to the higher layer signaling. The corresponding network device sends, which may be the sending of the high layer signaling at a layer corresponding to the high layer signaling of the network device. For example, the high layer signaling is RRC signaling, the terminal device receives the high layer signaling at the RRC layer, and/or the network device sends the high layer signaling at the RRC layer. For another example, the high layer signaling is MAC signaling, the terminal device receives the high layer signaling at a MAC layer (or a physical layer), and/or the network device transmits at a MAC layer (or a physical layer) High-level signaling.

It should be noted that the above FIG. 7 only schematically illustrates the embodiment of the present invention, but the present invention is not limited thereto. For example, the order of execution between the various steps can be appropriately adjusted, and other steps can be added or some of the steps can be reduced. Those skilled in the art can appropriately adapt to the above contents, and are not limited to the above description of FIG.

In an embodiment, the terminal device may further send a configuration completion message to the network device, where the configuration completion message is used to indicate to the network device that configuration of the configuration information is completed. For example, reference can be made to Figures 5 and 6 in Embodiment 1.

In an embodiment, the terminal device may further receive a PDCCH sent by the network device, where the PDCCH is used to schedule a physical downlink data channel where the high layer signaling is located. The period may also be a window, a time period, a duration, a period of time, etc., and the invention is not limited thereto.

In an embodiment, the terminal device determines an initial effective time of the configuration information, where the initial effective time is at least related to a period in which the high layer signaling is received. The terminal device receives or sends a physical signal by using part or all of the configuration information that is valid from the start of the configuration information. And/or, the network device starts to send or receive a physical signal by using part or all of the configuration information that is valid, starting from an effective time of part or all of the configuration information.

In this embodiment, the time when the network device sends the high layer signaling and the time when the terminal device receives the high layer signaling may be in the same period; however, the present invention is not limited thereto, and the following will be adopted. The example is explained.

FIG. 8 is a diagram showing an example of a period of higher layer signaling according to an embodiment of the present invention. For example, the high layer signaling shown in FIG. 8 is signaling that the network device sends to the terminal device that carries the configuration information. As shown in FIG. 8, the terminal device receives the high layer signaling in one cycle, and may use the starting point of the Sth period after the period of receiving the high layer signaling as the configuration of the RRC signaling bearer. The reference point of the effective time of the information, or the effective time point, S is a natural number.

Correspondingly, the network device sends the high-level signaling to the terminal device in one cycle, and the starting point of the subsequent S periods is used as the effective time reference point of the configuration information carried by the high-layer signaling, or the effective time point.

As described above, the receiving and transmitting in this embodiment are performed in the upper layer corresponding to the high layer signaling, so that the processing delay needs to be considered between receiving and transmitting in addition to the transmission delay. Or a time interval between the time when the network device sends the high-layer signaling and the high-level signaling received by the terminal device, where the time interval includes at least the high-level signaling in a physical environment. The transmission delay, and/or the processing delay of the network device to generate the high layer signaling, and/or the processing delay of the terminal device to read the high layer signaling. Therefore, there may be a case where the time point at which the network device transmits the high layer signaling is not in the same period as the time point at which the terminal device receives the high layer signaling. In this case, if the above method is directly used, the network device and the terminal device may be misunderstood for the position of the effective time reference point.

For example, the network device sends the high layer signaling in the #m period, and confirms the start position of the #(m+1) period as the initial effective time of the configuration information carried by the high layer signaling, and the terminal device The high layer signaling is received in the #(m+1) cycle, and the start position of the #(m+2) cycle is confirmed as the initial effective time of the configuration information, and a misunderstanding occurs between the two.

The high layer signaling is sent for a period of time in a period, the time period being located on the front of the one period on the time axis, the period of time being less than or equal to the duration of the period minus the processing delay, The processing delay is used by the terminal device to acquire the high layer signaling.

In this embodiment, the network device transmits in a time period before a cycle; for example, as shown in part A of the #m cycle in FIG. For example, the network device can coordinate high layers (eg, MAC layer and/or RRC layer, etc.) such that one RRC signaling is sent in a time period before a cycle; for example, as shown in Part A of Duration#m in FIG. For example, the one higher layer signaling needs to be guaranteed reliability and delay because it carries configuration information related to highly reliable low latency physical layer transmission.

For example, the duration of the time period is less than or equal to the duration of the period minus the processing delay of the terminal device processing the higher layer signaling, which corresponds to the portion B of the #m period in FIG. Thereby, the terminal device can be configured to receive the high layer signaling (eg, processing the received signal including the high layer signaling) and the network device sends the high layer signaling (eg, generating the receiving including the RRC signaling) The time points of the signal are in the same period, and the above misunderstanding can be avoided.

In this embodiment, the period may be configured by the network device for the terminal device. For example, it is configured as 10ms, 15ms, 20ms, etc.; or, configured as one frame, two frames, or P frames, etc., P is a positive integer; or, configured as Q subframes, etc., Q is a positive integer; or is configured as W For time slots, etc., W is a positive integer. In addition, the period may also be pre-agreed by the communication standard specification, or preset by the device before leaving the factory, and the specific value may be the same as above.

In addition, the period may be determined by the terminal device and/or the network device according to the specific content of the configuration information carried by the high layer signaling. For example, if the configuration information is used to configure related information of a receiving/transmitting beam, the period is 15 ms; for example, the configuration information is used to configure time-frequency resources of unscheduled uplink transmission, the period is 20 ms, and the like.

In this embodiment, the processing delay may be indicated by the network device by using signaling, or may be pre-agreed by the communication standard specification, or may be preset by the terminal device and/or the network device before leaving the factory. For example, if the configuration information is used to configure related information of a receiving/transmitting beam, the processing delay takes 10 ms; and, for example, the configuration information is used to configure a time-frequency resource of the unscheduled uplink transmission, the processing delay requirement is Take 15ms, and so on. In addition, the processing delay may also be determined by the terminal device and/or the network device according to the specific content of the configuration information carried by the high-layer signaling, and the specific value may be the same as above.

In addition, the processing delay may also be a processing delay requirement for the terminal device to process high layer signaling, for example, a maximum processing delay requirement. The processing delay may be indicated by the network device by signaling, or may be pre-agreed by the communication standard specification, or may be preset by the device before leaving the factory. The processing delay may also be determined by the terminal device and/or the network device according to the specific content of the configuration information carried by the high layer signaling. The specific numerical value can be, for example, the same as the above-described example of the processing delay.

In an embodiment, the initial effective time may be a starting position of the Sth period after the period in which the high layer signaling is received, and S is a natural number. The starting position of the Sth period after the period in which the high layer signaling is received may also be an effective reference point. For example, after the above-mentioned effective reference point, E ms is the initial effective time, or the subsequent F-th time unit (the starting position) is the initial effective time, and the time unit may be a frame, a subframe, a time slot. Or time domain symbols and so on. E and F are positive integers.

In an embodiment, the high layer signaling may further include third indication information, where the third indication information is used to indicate a system frame number and/or a subframe number and/or a location where the configuration information starts to take effect. Slot number.

In this embodiment, the RRC layer is used as an example. For example, the RRC layer of the network device may send an inquiry signaling to its MAC layer to query an appropriate transmission time. In addition, the RRC layer may notify the MAC layer, the RRC. Signaling needs to be sent in Part A of Figure 8. In addition, to avoid misunderstandings at the sender and receiver, the cycle may require orders of magnitude of 10 ms.

The definition of the boundary of the period in this embodiment is independent of the transmission time of the high layer signaling. That is, the period is defined by an absolute time, so the implementation method of this embodiment is a method of determining an initial effective time by an absolute time reference point. Compared with the solution of Embodiment 1, the embodiment of the present invention has less modification to the existing communication standard specification.

It can be seen from the foregoing embodiment that the terminal device determines an initial effective time of the configuration information, and the initial effective time is at least related to a period in which the high layer signaling is received. Thereby, the transmission reliability of the transmission configuration itself is improved and/or the configuration effective blur period during configuration is reduced.

Example 3

In order to improve the reliability of the physical layer transmission configuration effective time point, one method of the embodiment of the present invention is to use the existing physical layer HARQ mechanism to confirm the physical layer transmission configuration effective time point carried by the high layer signaling. The advantage of this method is that it directly establishes contact with physical transmission resources, which can effectively reduce the fuzzy understanding that may exist in the corresponding physical time of high-level signaling. However, there is more standardization work required to implement this method. In the standardization process, one of the above-described implementation methods can be selected based on the priority of the high-transmission-required service (for example, URLLC, etc.), the time required for standardization to provide time for the subject, and the like, and the respective advantages of the embodiments provided by the present invention.

As described above, if the existing physical layer HARQ mechanism is reused to solve the problem of improving the reliability of the physical layer transmission configuration effective time point, at least one of the problems is that the physical layer ACK cannot be established in the protocol architecture in the existing mobile communication system. The link between the NACK signal and higher layer signaling.

Therefore, in order to solve at least one of the above problems, an embodiment of the present invention provides a method for receiving and transmitting information. FIG. 9 is a schematic diagram of an information receiving and transmitting method according to an embodiment of the present invention, showing a situation on the terminal device side. As shown in FIG. 9, the method includes:

Step 901: The terminal device receives a physical downlink control channel sent by the network device, where the physical downlink control channel is used to schedule a physical downlink data channel where the upper layer signaling is located.

Step 902: The terminal device receives the high layer signaling sent by the network device, where the high layer signaling includes at least configuration information related to the terminal device receiving or transmitting a physical layer signal;

Step 903: The terminal device sends, to the network device, a response signal for indicating that the physical downlink data channel is correctly received, and the initial effective time of the configuration information is at least related to the response signal.

For example, the response signal used to indicate that the physical downlink data channel is correctly received may be an ACK signal, or other control information used to indicate that the physical downlink data channel is correctly received, etc.; the present invention is not limited thereto. .

In this embodiment, the start effective time of the configuration information is at least related to the response signal, for example, the start effective time of the configuration information may be related to at least the time unit of the response signal, or The initial effective time of the configuration information may be confirmed based on at least a time unit in which the response signal is located. For another example, the start effective time of the configuration information may be related to at least the sending manner of the response signal, or the start effective time of the configuration information may be confirmed based on at least the sending manner of the response signal.

In this embodiment, the part that is effective from the initial effective time may be, for example, part or all of the configuration information.

In this embodiment, the terminal device may further determine, according to the response signal, an initial effective time of the configuration information. The terminal device receives or sends a physical signal by using part or all of the configuration information that is valid from the start of the configuration information. And/or, the network device starts to send or receive a physical signal by using part or all of the configuration information that is valid, starting from an effective time of part or all of the configuration information.

It should be noted that the above FIG. 9 only schematically illustrates the embodiment of the present invention, but the present invention is not limited thereto. For example, the order of execution between the various steps can be appropriately adjusted, and other steps can be added or some of the steps can be reduced. Those skilled in the art can appropriately adapt according to the above, and are not limited to the description of FIG. 9 described above.

In an embodiment, the physical downlink control channel is further configured to indicate that an effective time of the configuration information carried by the high layer signaling is related to a time unit in which the response signal is located.

For example, the PDCCH indicates that the current transmission is the high layer signaling, and the effective time of the high layer signaling is the time unit of the response signal (for example, ACK) of the PDSCH carrying the high layer signaling as a reference point. For example, the information may be RRC signaling for configuring physical layer transmission.

For another example, the effective time of the configuration information may start from the Xth time unit after the time unit in which the response signal is located, and X is a positive integer.

In another embodiment, a MAC header including a MAC packet in which the high layer signaling is located is used to indicate an effective time of the configuration information carried by the high layer signaling and a time when the MAC packet is received. Unit related.

For example, the high-level signaling of the current transmission is indicated by the MAC Header to the terminal device, and the effective time of the high-level signaling is based on the time unit in which the MAC Header is received. For example, the higher layer signaling may be RRC signaling for configuring physical layer transmission.

For another example, the effective time of the configuration information may start from the Yth time unit after receiving the time unit of the MAC packet, and Y is a positive integer.

In another embodiment, the high layer signaling may further include fourth indication information, where the fourth indication information is used to indicate a system frame number and/or a subframe number where the configuration information starts to take effect and/or Or slot number.

From the perspective of the development trend of future communication systems, an increasingly flexible physical layer transmission mechanism is a development trend. The flexible physical layer transmission mechanism can meet the transmission requirements of data services with different transmission requirements, and can effectively save physical resources, improve the efficiency of using physical resources, and finally achieve an effect of using physical resources on demand. In order to better support the flexible physical layer transmission mechanism, accurate configuration information transmission and the like will become necessary. The solution of this embodiment can reduce the future standardization work and reduce the equipment design and development cost in the future system upgrade.

It can be seen from the foregoing embodiment that the effective time of the configuration information carried by the high layer signaling is indicated by the PDCCH or the MAC packet. Thereby, the transmission reliability of the transmission configuration itself is improved and/or the configuration effective blur period during configuration is reduced.

Example 4

Therefore, an embodiment of the present invention provides a method for receiving and transmitting information. FIG. 10 is a schematic diagram of an information receiving and transmitting method according to an embodiment of the present invention, showing a situation of a terminal device side and a network device side. As shown in FIG. 10, the method includes:

Step 1001: The terminal device receives high layer signaling sent by the network device, where the high layer signaling includes at least configuration information related to the terminal device receiving or transmitting a physical layer signal;

Step 1002: The terminal device determines, according to the fifth indication information, an initial effective time of the configuration information, where the fifth indication information is carried by the high layer signaling.

Therefore, in this embodiment, since the initial effective time of the configuration information is related to at least the fifth indication information that is included in the high-layer signaling by the terminal device, the physical layer transmission configuration effective time can be improved. The accuracy of the points in turn increases reliability, or can increase the transmission reliability of the transmission configuration itself and/or reduce the configuration validation blur period during configuration.

For example, the fifth indication information is used to indicate a system frame number and/or a subframe number and/or a slot number where the configuration information starts to be effective.

In this embodiment, the terminal device determines, according to the fifth indication information, an initial effective time of the configuration information, where the fifth indication information is carried by the high layer signaling. Valid from the initial effective time, for example, may be part or all of the configuration information. The terminal device may further determine an initial effective time of the configuration information based on at least the response signal. The terminal device receives or sends a physical signal by using part or all of the configuration information that is valid from the start of the configuration information. And/or, the network device starts to send or receive a physical signal by using part or all of the configuration information that is valid, starting from an effective time of part or all of the configuration information.

In this embodiment, the effective time of the configuration information is indicated by at least high layer signaling of the bearer configuration information. The method is simple and straightforward, and is easy to implement. However, since the logical signaling is not necessarily related to the physical time and the system frame length directly corresponding to the physical time is 10 ms, the effective time indicated by the high layer signaling may be The time interval between the receiving moments of the higher layer signaling is longer.

As mentioned earlier, future mobile communications have the ability to support flexible mobile communication services. This method is suitable for services that are not sensitive to delay but have high reliability requirements. The above embodiments of the present invention can be appropriately selected according to the transmission requirements of the service to improve the reliability of the physical layer transmission configuration effective time point and provide a solution for the corresponding mobile service that meets the transmission requirements and is cost-effective.
