However, the following description describes a New Radio (NR) system for purposes of example, and NR terminology is used in much of the description below, although the techniques may also be applied to applications other than NR system applications, such as 6th Generation (6G) communication systems.

Fig. 1 shows a block diagram of a wireless communication system to which embodiments of the present application are applicable.

Wherein, the terminal 11 may also be called as a terminal Device or a User Equipment (UE), the terminal 11 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer) or a notebook Computer, a Personal Digital Assistant (PDA), a palmtop Computer, a netbook, a super-Mobile Personal Computer (UMPC), a Mobile Internet Device (MID), a Wearable Device (Wearable Device) or a vehicle-mounted Device (VUE), a pedestrian terminal (PUE), and other terminal side devices, the Wearable Device includes: bracelets, earphones, glasses and the like.

For convenience of understanding, some contents related to the embodiments of the present application are described below:

in a New Radio (NR) communication mechanism, a terminal is scheduled to receive downlink data in two modes, namely dynamic scheduling and semi-static scheduling. For dynamic scheduling, before scheduling the terminal to receive data each time, the network device allocates downlink resources through the downlink scheduling signaling to allow the terminal to receive data. For semi-persistent scheduling, a network device configures a period of a periodic downlink Resource through Radio Resource Control (RRC) signaling, indicates a starting position of the periodic downlink Resource through downlink scheduling signaling, and a terminal periodically receives downlink data using a subsequent Resource position from the Resource starting position indicated by the network device. For example, the resource repetition period configured by the network device is 2 symbols, and the starting position of the resource start indicated by the Downlink Control Information (DCI) is the first subframe of which the System Frame Number (SFN) is 0, the terminal receives data from the starting resource at every two symbols in the corresponding resource position.

The network device issues a scheduling signaling on a Physical Downlink Control Channel (PDCCH), the terminal receives data on a Physical Downlink Shared Channel (PDSCH), and a time-frequency resource required for receiving the data on the PDSCH is indicated by the DCI. In the existing mechanism, after the terminal receives the scheduling signaling, it is necessary to attempt to receive data on the PDSCH under normal conditions (e.g., the terminal does not perform BWP (Bandwidth Part) handover). When data is received, an attempt is made to decode the received data. If the decoding is successful, an Acknowledgement (ACK) is fed back to indicate that the network device has successfully received, and the subsequent network device does not continue to schedule the terminal to receive the same data. If the decoding is unsuccessful, a Negative Acknowledgement (NACK) is fed back to indicate that the network device did not successfully receive, and the subsequent network device may reschedule the terminal to receive the same data.

However, in the NTN scenario, the network device may configure the terminal to disable uplink feedback on the downlink data, and transmit the downlink data in a manner such as blind scheduling. That is, the network device does not base on uplink feedback of the terminal, and the network device may schedule the terminal to receive the same data on multiple resource locations. In the case that the terminal has successfully decoded the data, if the terminal continues to receive the same data, unnecessary power consumption may be caused, and the scheme of the present application is proposed for this purpose.

The following describes in detail a data receiving method, an apparatus, a terminal and a readable storage medium provided in the embodiments of the present application with reference to the accompanying drawings and specific embodiments and application scenarios thereof.

Referring to fig. 2, fig. 2 is a flowchart of a data receiving method according to an embodiment of the present application, where the method is executed by a terminal, and as shown in fig. 2, the method includes the following steps:

step 201, the terminal stops receiving the target data under the condition that the first data is decoded successfully;

the target data is the first data retransmitted by the network equipment; the first data is transmitted through a first Hybrid automatic repeat request (HARQ) process, and uplink feedback of the first HARQ process is disabled. It can be understood that the uplink feedback of the first HARQ process is disabled, that is, the terminal does not need to feed back the data sent by the network device through the first HARQ process, that is, the terminal feeds back to the network device whether the data is successfully received (ACK) or unsuccessfully received (NACK).

In this embodiment, the network device may perform downlink allocation for the terminal, where the downlink allocation may be understood as transmission resources of the first data, and specifically may include resources for newly transmitting the first data and retransmission resources for retransmitting the first data, where the resources for newly transmitting the first data may be understood as resources for first transmission of the first data, and the first data may be understood as downlink data. The terminal may attempt reception of the first data through the first HARQ process based on the transmission resources allocated by the network device.

Optionally, when the network device allocates downlink allocation to the terminal, the terminal may be configured to disable feedback of the first HARQ process, and at this time, the terminal will not feed back a Hybrid automatic repeat request acknowledgement (HARQ-ACK) to the network device no matter whether the terminal receives the first data.

It should be understood that, in this embodiment of the application, each time the terminal receives the first data through the first HARQ process, the terminal may determine whether the currently received first data is successfully decoded, and stop receiving the first data retransmitted by the network device under the condition that the decoding is successful, so that unnecessary power consumption and power waste caused by the terminal receiving the first data on subsequent retransmission resources of the first data may be avoided.

Optionally, in some embodiments, the stopping of receiving, by the terminal, the target data includes:

and the physical layer of the terminal stops receiving the target data.

In other words, in the embodiment of the present application, stopping reception of target data is performed by the physical layer. It should be understood that the physical layer may perform the action of stopping receiving the target data by itself (e.g., through terminal internal interaction, if the physical layer knows that the first data has been successfully decoded, the physical layer stops receiving the first data retransmitted by the network device), and the physical layer may also perform the action of stopping receiving the target data based on an indication of another layer, for example, in some embodiments, the physical layer may be instructed by a Medium Access Control (MAC) layer to perform the action of stopping receiving the target data. In this case, the stopping of the reception of the target data by the terminal includes:

a Media Access Control (MAC) layer of the terminal sends first indication information to a physical layer;

and the physical layer of the terminal stops receiving the target data according to the first indication information.

In this embodiment of the application, the MAC layer includes a MAC entity, a HARQ entity, and a HARQ process, and specifically, one or more of the MAC entity, the HARQ entity, and the HARQ process may send indication information to the physical layer to indicate the physical layer to stop receiving the target data. In other words, in some embodiments, the MAC layer of the terminal sending the first indication information to the physical layer comprises at least one of:

the MAC entity sends first sub-indication information to the physical layer;

the HARQ entity of the terminal sends second sub-indication information to the physical layer;

and the HARQ process of the terminal sends third sub-indication information to the physical layer.

In this embodiment of the application, the first sub-indication information, the second sub-indication information, and the third indication information have the same function, and are all used to indicate the physical layer to stop receiving the target data. However, the content carried by the first sub-indication information, the second sub-indication information and the third indication information may be the same or different, and is not further limited herein.

For the MAC entity sending the first sub-indication information to the physical layer, instructing the physical layer to stop receiving the first data includes the following cases:

in some embodiments, for dynamic scheduling, assuming that a MAC entity receives a first downlink allocation sent by a network device, the MAC entity determines that the first downlink allocation is a retransmission resource of first data through MAC layer interaction, and the first data has been successfully decoded, and then the MAC entity instructs a physical layer to stop receiving the first data corresponding to the first downlink allocation.

In some embodiments, the network device configures a downlink Aggregation transmission, such as a PDSCH Aggregation (PDSCH-Aggregation) function, to the terminal, which is simply understood as, for example, RRC configures a downlink Aggregation transmission factor PDSCH-Aggregation factor of 4, which indicates that the network device will have three retransmissions after a new transmission, indicates downlink resources required for four data transmissions through a scheduling signaling (e.g., DCI), and instructs the physical layer to stop receiving the first data of a subsequent retransmission when the MAC entity determines that the first data has been successfully decoded through the MAC layer interaction. For example, assuming that the PDSCH-aggregation factor is 4, the MAC layer instructs the physical layer to stop receiving the three subsequent retransmissions of data if it determines that the newly transmitted data has been successfully decoded.

In some embodiments, the network device configures semi-static resources and the semi-static resources configure downlink aggregate transmission, which is simply understood as RRC configuring a downlink aggregate transmission factor PDSCH-aggregation factor of 4, the semi-static resources configured in each period may be used for new transmissions and three retransmissions. And if the MAC entity determines that the first data is successfully decoded through interaction in the MAC layer, the MAC entity instructs the physical layer to stop receiving the first data retransmitted by the subsequent network. For example, assuming that the PDSCH-aggregation factor is 4, if the MAC layer determines that the newly transmitted data has been successfully decoded, the physical layer is instructed to stop receiving the three subsequent retransmissions.

For the HARQ entity sending the second sub-indication information to the physical layer, indicating that the physical layer stops receiving the first data includes the following cases:

in some embodiments, the HARQ entity receives HARQ information corresponding to a first downlink allocation, and when it is determined that the first downlink allocation is a retransmission resource of first data based on an interaction in a MAC layer and the first data has been successfully decoded, the HARQ entity instructs a physical layer to stop receiving the first data retransmitted by the network device.

In some embodiments, the network device configures downlink aggregate transmission for the terminal, and instructs the physical layer to stop receiving subsequent retransmitted first data if the HARQ entity determines that the first data has been successfully decoded. For example, if the HARQ entity determines that the newly transmitted first data transmitted by the aggregated transmission scheme has been successfully decoded, the HARQ entity instructs the physical layer to stop receiving the retransmitted first data transmitted by the aggregated transmission scheme.

In some embodiments, the network device configures a semi-static resource and the semi-static resource configures downlink aggregate transmission, and if the HARQ entity determines that the first data has been successfully decoded, the network device instructs the physical layer to stop receiving subsequent retransmission data. For example, the HARQ entity determines that the newly transmitted first data transmitted by the aggregated transmission scheme has been successfully decoded, and instructs the physical layer to stop receiving the retransmitted first data transmitted by the aggregated transmission scheme.

For the HARQ process sending the third sub-indication information to the physical layer, instructing the physical layer to stop receiving the first data includes the following cases:

the HARQ process determines that the first downlink allocation is retransmission resource of the first data based on the received HARQ information associated with the first downlink allocation, and the first data is successfully decoded, and the HARQ process instructs a physical layer to stop receiving the first data retransmitted by the network equipment.

Optionally, in some embodiments, after the step of sending, by the MAC entity, the first sub-indication information to the physical layer, the method further includes:

in the case that the MAC entity determines that a first downlink allocation is a retransmission resource of the first data, the MAC entity stops transmitting target information to the HARQ entity associated with the first downlink allocation;

the target information includes second indication information and HARQ information associated with the first downlink allocation, where the second indication information is used to indicate that the first downlink allocation exists.

It should be understood that the MAC entity stops sending the target information to the HARQ entity associated with the first downlink assignment, which may be understood as that the MAC entity does not send the target information to the HARQ entity associated with the first downlink assignment, i.e. the MAC entity does not send the target information.

The embodiment of the application is applied to a dynamic scheduling scene, and the network equipment dynamically schedules the terminal to perform downlink receiving in the dynamic scheduling process. After the MAC entity indicates the first sub-indication information to the physical layer, the physical layer stops receiving the first data, so that the MAC entity does not indicate the existence of the first downlink assignment to the HARQ entity and does not send HARQ information associated with the first downlink assignment to the HARQ entity, which can prevent the HARQ entity and the HARQ process from executing an invalid processing procedure, thereby improving the system performance of the terminal.

Optionally, in some embodiments, after the step of the HARQ entity transmitting the second sub-indication information to the physical layer, the method further includes:

and under the condition that the HARQ entity determines that the first downlink allocation associated with the received HARQ information is the retransmission resource of the first data, the HARQ entity stops directing the HARQ information associated with the first downlink allocation to the HARQ process corresponding to the HARQ information.

It should be understood that the HARQ entity stopping directing the HARQ information of the first downlink assignment association to the HARQ process corresponding to the HARQ information may be understood as: the HARQ entity does not direct The HARQ information associated with The first downlink assignment to The HARQ process corresponding to The HARQ information (e.g., The HARQ information from The HARQ information direct HARQ information to The correcting HARQ process).

The embodiment of the application is applied to a dynamic scheduling scene, and the network equipment dynamically schedules the terminal to perform downlink receiving in the dynamic scheduling process. After the MAC entity receives the HARQ information corresponding to the first downlink assignment, the physical layer stops receiving the first data, so that the HARQ entity does not direct the HARQ information associated with the first downlink assignment to the HARQ process corresponding to the HARQ information, which can avoid the HARQ process from executing an invalid processing procedure, thereby improving the system performance of the terminal.

It should be understood that the content included in the first indication information may be set according to actual needs, and optionally, in some implementations, the first indication information includes at least one of the following: downlink allocation information and HARQ process information.

For downlink allocation information, it can be understood that: and the MAC layer is supposed to confirm that the first downlink allocation is the retransmission resource of the first data and the first data is successfully decoded, and then the MAC layer is instructed to stop receiving the downlink data corresponding to the first downlink allocation.

For HARQ process information can be understood as: assuming that the first data is transmitted through the first HARQ process, if the MAC confirms that the first downlink allocation is a retransmission resource of the first data and the first data has been successfully decoded, the MAC instructs the physical layer to stop receiving data corresponding to the first HARQ process.

It should be understood that the above-mentioned first indication information is used to indicate any one of: the physical layer stops receiving the first data retransmitted by the network equipment next time, and the physical layer stops receiving all the retransmitted first data by the network equipment after the decoding of the first data is successful.

In this embodiment of the application, the first indication information of the MAC layer may indicate that the physical layer stops receiving the first data retransmitted by the network device only once, or may indicate that the physical layer stops receiving the first data retransmitted by the network device multiple times.

For example, the network device configures downlink aggregation transmission for the terminal, for example, the RRC configures a downlink aggregation transmission factor (e.g., PDSCH-aggregation factor) to be 4, and the MAC layer successfully decodes the first data newly transmitted by the network device, and instructs the physical layer to stop receiving the first data retransmitted by the subsequent network device. For example, the MAC layer may send first indication information for three times, which respectively indicates the physical layer to stop receiving the first data retransmitted by the network device for the first time, the second time, and the third time. The first indication information may also be sent once to indicate the physical layer to stop receiving the first data retransmitted by the network device for the first time, the second time, and the third time.

Optionally, in some embodiments, the behavior of the terminal to stop receiving the target data includes at least one of:

the terminal discards retransmission resources allocated by the network equipment;

the terminal ignores retransmission resources allocated by the network equipment;

the terminal stops receiving data at a resource position corresponding to the retransmission resource allocated by the network equipment;

wherein the retransmission resource is a resource used by the network device to retransmit the first data.

In this embodiment of the present application, the retransmission resource refers to a resource used for retransmitting the first data after the first data is successfully decoded. It should be understood that ceasing to receive data may be understood as not attempting to receive data.

And discarding retransmission resources allocated by the network equipment for the terminal, for example, the network equipment allocates resources for newly transmitting the first data at time t1, allocates resources for retransmitting the first data at time t2, and if the first data received by the resources allocated at time t1 has been successfully decoded, the UE discards the resources allocated at time t2 for retransmitting the first data.

Ignoring the retransmission resources for the terminal, e.g., the network device allocating resources to newly transmit the first data at time t1, allocating resources to retransmit the first data at time t2, and if the first data received over the resources allocated at time t1 has been successfully decoded, the UE ignoring the resources allocated at time t2 to retransmit the first data.

For the terminal to stop receiving data at the resource position corresponding to the retransmission resource, for example, the network device allocates resource to newly transmit the first data at time t1, allocates resource to retransmit the first data at time t2, and if the first data received by the resource allocated at time t1 has been successfully decoded, the UE stops receiving or does not attempt to receive the first data at the resource position allocated at time t2 to retransmit the first data.

Optionally, in some embodiments, before the terminal stops receiving the target data, the method further includes:

the terminal determines the retransmission resource according to the target parameter; wherein the target parameter includes at least one of HARQ information associated with the first downlink allocation and retransmission information configured by the network device.

In this embodiment of the application, whether downlink allocation is retransmission resource of the first data may be determined based on at least one of HARQ information and retransmission information.

Optionally, in some embodiments, when determining the retransmission resource using HARQ information, the HARQ information includes a New Data Indicator (NDI) parameter value, and the determining, by the terminal, the retransmission resource according to HARQ information associated with a first downlink allocation includes:

and when the NDI parameter value associated with the first downlink allocation is not changed relative to the last scheduling, the terminal determines that the first downlink allocation is the retransmission resource.

It should be noted that the NDI field may be an extended parameter field (e.g., two bits). Because the uplink feedback is disabled, when some DCI is lost, the terminal may be caused to erroneously determine whether the DCI carries the retransmission resource or the new transmission resource. The correctness of judging whether the downlink resource is the retransmission resource or the newly transmitted resource by the terminal can be further ensured through the expanded NDI.

In this embodiment of the present application, it is assumed that first data is transmitted through a first HARQ process, and a terminal receives a first downlink assignment (that is, downlink scheduling), and determines that an NDI parameter associated with the first downlink assignment is not changed with respect to scheduling of the first HARQ process last time, so that it is determined that the first downlink assignment is a retransmission resource of the first data.

Optionally, in some embodiments, when the retransmission resource is determined using retransmission information, the retransmission information includes a number of times of retransmission of the first data.

For example, the network device configures downlink aggregation transmission for the terminal, for example, configures PDSCH-aggregation factor to 4 by RRC, and the network device provides four resource locations through downlink scheduling signaling, so that the terminal may determine that the four resource locations respectively correspond to a new transmission resource, a first retransmission resource, a second retransmission resource, and a third retransmission resource.

In example two, the network device configures a semi-static resource and the semi-static resource configures downlink aggregation transmission, for example, by configuring PDSCH-aggregation factor 4 by RRC, the network device configures four semi-static resources to the terminal in each period, and then the terminal may determine that the four resource positions respectively correspond to a new transmission resource, a first retransmission resource, a second retransmission resource, and a third retransmission resource.

It should be noted that, in the data receiving method provided in the embodiment of the present application, the execution main body may be a data receiving apparatus, or a control module in the data receiving apparatus for executing the data receiving method. In the embodiment of the present application, a data receiving apparatus executes a data receiving method as an example, and the data receiving apparatus provided in the embodiment of the present application is described.
