Description

Information processing method, terminal and computer storage medium

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information processing method, a terminal, and a computer storage medium.

Background

Currently, in a fifth Generation wireless communication (5Generation New Radio access technology, 5G NR) system, there are services with different priorities, delay requirements, or transmission time intervals. The services with extremely high time delay and high reliability requirements are sporadic and irregular, so that the type of services can be configured to be multiplexed and transmitted on the same resource with other services with different requirements, so as to improve the resource utilization rate. However, when multiplexing transmission in this way, a situation may occur in which data of one terminal conflicts with traffic data having a different priority on the same resource.

For downlink data transmission, the base station may directly transmit the high-priority service data covering the low-priority service data, but if the terminal receiving the low-priority service data does not know that the base station performs such processing, the terminal receives the data of other terminals as its own data, so that the detection performance is reduced, and when retransmission occurs, the data damaged by other terminals is combined with the retransmission, thereby causing error propagation. Therefore, in order to solve the problem, preemption (preemption) indication information is introduced to notify a terminal of a low-priority service that a resource preempted by other terminals exists in the transmission resource of downlink data, so that the terminal can correctly process the received downlink data.

For uplink data transmission, since different terminals transmit data, if two terminals do not know resource collision and transmit respective data on the same resource, mutual interference occurs, so to avoid mutual interference, interrupt indication information is introduced for notifying the terminal of low priority service to stop transmitting data on the overlapped resource, so as to ensure normal transmission of high priority data.

However, the PDCCH currently used for carrying the preemption indication information or interruption indication information is multicast for a group of terminals, and the preemption indication information or interruption indication information received in the group of terminals is the same. However, it is still impossible for the current terminal to determine whether the preemption indication information or the interruption indication information is valid, and if the terminal directly performs processing according to the preemption indication information or the interruption indication information, that is, determines that part of the data of the terminal is preempted or interrupted, the terminal may not meet the actual data transmission situation. For example, if the terminal receives the preemption indication information or interruption indication information, but actually the current service type of the terminal is high priority, there is no case of preemption or interruption by other terminals, which may cause information transmission errors or degrade the performance of the communication system.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

The technical background of the embodiments of the present invention is described below.

The PDCCH for carrying the instruction information for preemption or the interruption instruction information is multicast for a group of terminals, and the instruction information for preemption or the interruption instruction information received by the group of terminals are the same. However, it is still impossible for the current terminal to determine whether the preemption indication information or the interruption indication information is valid, and if the terminal directly performs processing according to the preemption indication information or the interruption indication information, that is, determines that part of the data of the terminal is preempted or interrupted, the terminal may not meet the actual data transmission situation. For example, if the terminal receives the preemption indication information or interruption indication information, but actually the current service type of the terminal is high priority, there is no case of preemption or interruption by other terminals, which may cause information transmission errors or degrade the performance of the communication system.

In view of this, an embodiment of the present invention provides an information processing method, in which a terminal may compare whether a transmission length of a first channel in a time domain is equal to a preset threshold to determine whether first indication information is valid, so that the terminal may perform corresponding processing according to whether the first indication information is valid, thereby avoiding an occurrence of an information transmission error and improving performance of a communication system.

The technical scheme provided by the embodiment of the invention is described below by combining the accompanying drawings.

Referring to fig. 1, an embodiment of the present invention provides an information processing method, which may be executed by a terminal, where the terminal may be implemented by a device such as a mobile phone or a tablet computer (PAD). The flow of the method is described below.

S101: the terminal determines a transmission length of the first channel in the time domain.

In this embodiment of the present invention, the first CHannel may be a Physical Downlink Shared CHannel (PDSCH), or may also be a Physical Uplink Shared CHannel (PUSCH).

When the base station schedules the PDSCH for the terminal to perform downlink data transmission of the terminal, or the base station schedules the terminal to perform uplink data transmission of the terminal through the PUSCH, the base station notifies the terminal of the transmission length of the first channel in the time domain through the scheduling signaling. For example, the base station may notify the terminal through a control signaling transmitted through a Physical Downlink Control Channel (PDCCH), and the terminal may determine the transmission length of the first channel according to the control signaling transmitted on the PDCCH for scheduling the first channel. Or, the base station pre-configures a transmission length to the terminal through a high-level signaling, and when the terminal receives a PDCCH for scheduling a channel transmission, the channel is transmitted according to scheduling information in the PDCCH and the transmission length pre-configured by the high-level signaling, that is, the transmission length is not notified by different PDCCHs, so the terminal can also determine the transmission length of the first channel according to the information configured through the high-level signaling; of course, the transmission length may also be predetermined without signaling, and both the terminal and the network side or the base station know the transmission length.

S102: the terminal determines whether the transmission length of the first channel is greater than or equal to a preset threshold.

In the embodiment of the present invention, the base station may pre-configure the specific value of the preset threshold to the terminal through a high-level signaling, or the specific value of the preset threshold may also be a value pre-agreed by the terminal and the base station. The preset threshold may be, for example, a value not exceeding 14, such as 2, 4, or 7, and of course, other possible values may also be used, which is not limited in this embodiment of the present invention.

S103: and if the determination result is yes, the terminal determines that the first indication information is valid.

If the terminal obtains the transmission length of the first channel, and after the transmission length of the first channel is compared with the preset threshold value, the terminal determines that the transmission length of the first channel is greater than or equal to the preset threshold value, and then the terminal can determine that the first indication information is valid. If the first indication information is valid for the terminal, it indicates that the transmission resource of the first channel of the terminal is preempted or interrupted by data of other high-priority services, and then the terminal may perform corresponding processing according to the first indication information.

Specifically, the first indication information may be preemption indication information or interruption indication information. The terminal may determine, according to the first indication information, a resource location to be preempted or interrupted in the transmission resource of the first channel. Specifically, the first indication information may indicate a preemption or interruption condition in a reference resource, where the reference resource includes a transmission resource of the first channel but may be a resource set larger than the transmission resource of the first channel, so as to notify preemption or interruption conditions of multiple terminals to the multiple terminals through the same first indication information at the same time, so as to save signaling overhead. The reference resource is divided into a plurality of sub-blocks in advance in a time domain and a frequency domain according to a specific granularity, for example, 1 part in the frequency domain and 14 parts in the time domain, one sub-block includes 14 sub-blocks, each sub-block corresponds to the indication information in the 1-bit first indication information, the 14-bit first indication information can indicate whether preemption or interruption exists in each block in the reference resource, and different terminals can judge which positions in the transmission resource of the first channel of the different terminals have preemption or interruption according to which sub-blocks the transmission resource of the first channel of the different terminals corresponds to in the reference resource.

If the first channel is the PDSCH, the terminal may set, after receiving the data carried by the first channel, the received data in the resource location, which is determined according to the indication of the first indication information, of the first channel to 0, because this part of data is not the data of the terminal in fact, but the data from other terminals, and after setting to 0, the data is input to the decoder as the received information, so that interference of the data of other terminals to the terminal may be avoided. Of course, if the decoding of the first channel of the terminal fails and retransmission is required, when the terminal receives the retransmitted data and combines the retransmitted data with the previously received data, the terminal does not combine the part of the previously received data that indicates preemption, so as to avoid the retransmission data of the terminal from being damaged by the data transmitted by other terminals in the part, thereby causing error propagation.

If the first channel is the PUSCH, when the terminal performs uplink data transmission through the first channel, the terminal needs to stop transmitting on the interrupted resource in the transmission resources of the first channel determined according to the first indication information, so as to avoid interference on the high-priority data.

S104: if the determination result is negative, the terminal determines that the indication information is invalid.

If the terminal obtains the transmission length of the first channel, and after the transmission length of the first channel is compared with the preset threshold value, the terminal determines that the transmission length of the first channel is smaller than the preset threshold value, and then the terminal can determine that the first indication information is invalid. If the first indication information is invalid for the terminal, which indicates that the transmission resource of the first channel of the terminal is not preempted or interrupted, the terminal may perform processing according to any one of the following processing manners:

(1) the terminal may determine not to receive the first indication information, and then the terminal does not need to monitor (receive) the PDCCH when reaching the transmission opportunity of the PDCCH carrying the first indication information.

(2) The terminal determines not to receive first indication information corresponding to a reference resource containing transmission resources of the first channel. Wherein, a first indication information corresponds to a reference resource, the reference resource at least comprises the transmission resource of the first channel; for example, the preemption indication information used for indicating that the transmission resource in the PDSCH is preempted corresponds to a downlink reference resource, and the first indication information may indicate which resource blocks of a plurality of divided resource blocks in the downlink reference resource are preempted by other high priority information, and the information of the first indication information on the resource blocks is covered by other information. Or, the interruption indication information for indicating that the transmission resource of the PUSCH is interrupted corresponds to an uplink reference resource, and the first indication information may indicate which resource blocks of the plurality of resource blocks divided in the uplink reference resource are required to be used for other information transmission, and the first indication information needs to stop transmission on the resource blocks.

(3) If the first channel is a PUSCH, the terminal may determine not to receive the first indication information before a start symbol of the PUSCH.

(4) If the first channel is the PDSCH, the terminal may determine not to receive the first indication information after the end symbol of the PDSCH.

(5) If the first channel is the PDSCH, the terminal may determine not to receive the first indication information after receiving the end symbol of the PDSCH and before receiving the PDCCH that schedules the PDSCH.

(6) If the first channel is the PDSCH, the terminal may determine not to receive the first indication information until the next PDSCH is received after receiving the end symbol of the PDSCH.

(7) The terminal may receive the indication information without parsing the first indication information. For example, in the process of receiving the first indication information by the terminal, before determining that the first indication information is invalid, that is, the terminal has received the first indication information, the terminal may not decode and parse the received first indication information in the bit domain.

(8) The terminal may also ignore the content obtained by the analysis after receiving and analyzing the indication information. For example, if the terminal has completed decoding and parsing the indication information to determine that the first indication information is invalid, the terminal may not operate according to the content acquired by decoding and parsing.

In the embodiment of the present invention, before the terminal has received the scheduling signaling for scheduling the first channel but has not obtained the transmission length of the first channel according to the scheduling signaling, if the terminal has been configured to monitor the PDCCH carrying the first indication information, the terminal needs to monitor the first indication information at a transmission opportunity (transmission opportunity) of the indication information in the PDCCH.

When monitoring or receiving the first indication information, the terminal substantially monitors or receives the PDCCH carrying the first indication information. The first indication information may be transmitted, for example, through a PDCCH scrambled by an Interrupt (INT) -Radio Network Temporary Identifier (RNTI).

In the embodiment of the present invention, since the base station knows the transmission length of the first channel of the terminal all the time, the base station can also know the corresponding action to be performed by the terminal by comparing the transmission length of the first channel of the terminal with the preset threshold. Therefore, referring to fig. 2, an embodiment of the present invention further provides an information processing method, which can be executed by a base station, and a flow of the method is described as follows.

S201: the base station determines a transmission length of a first channel for transmitting data of the first terminal.

Specifically, since the first channel is scheduled by the base station, the base station itself knows the transmission length of the first channel of the first terminal.

Correspondingly, the first channel may be a PDSCH; alternatively, the first channel may be a PUSCH.

S202: the base station determines whether the transmission length of the first channel is greater than or equal to a preset threshold.

The preset threshold may be a value pre-configured to the base station through a high-level signaling; or, the preset threshold is a value predetermined by the base station and the first terminal.

S203: and if so, the base station determines that the first indication information is valid for the first terminal.

When the base station determines that the transmission length of the first channel is greater than or equal to the preset threshold, the base station determines that the first indication information is valid for the first terminal, and then the base station may determine that the first terminal will receive the first indication information and may determine, according to the first indication information, a resource position to be preempted or interrupted in the transmission resource of the first channel.

S204: and if the determination result is negative, the base station determines that the first indication information is invalid for the first terminal.

When the base station determines that the transmission length of the first channel is smaller than the preset threshold, the base station determines that the first indication information is invalid for the first terminal, and the base station may determine that the first terminal may perform one of the following processes:

the base station determines that the first terminal does not receive first indication information corresponding to a reference resource containing transmission resources of a first channel; or,

if the first channel is a PUSCH, the base station determines that the first terminal does not receive the first indication information before the initial symbol of the PUSCH; or,

if the first channel is the PDSCH, the base station determines that the first terminal does not receive the first indication information after the end symbol of the PDSCH; or,

the base station determines that the first terminal ignores the indication content of the first indication information.

In the embodiment of the present invention, no matter whether the first indication information is valid for the first terminal, the base station needs to transmit the first indication information in the transmission opportunity of the indication information in the PDCCH to notify the plurality of terminals that need to know, where the plurality of terminals may include the first terminal.

In the following, the technical solutions of the embodiments of the present invention will be explained based on two specific examples.

Referring to fig. 3, the base station transmits the scheduling signaling to the terminal 1, i.e. PDCCH for eMBB, downlink data transmission on the PDSCH by terminal 1 is scheduled on a slot (slot) n, i.e., the eMBB PDSCH, in which downlink data of the terminal 1 is data of a low priority service, i.e., enhanced Mobile BroadBand (eMBB) service, and at the same time, the base station also transmits, through scheduling signaling to the terminal 2, i.e. PDCCH for URLLC, that schedules downlink data transmission on the PDSCH by terminal 2 within the same slot, i.e. slot n, i.e., URLLC PDSCH, downlink data for terminal 2 is transmitted on symbol number 10, downlink data for terminal 2 is data for high priority traffic, that is, a high-Reliable Low Latency Connection (URLLC) service, in order to meet the Low Latency requirement of the URLLC, the base station covers the downlink data of the terminal 2 with the data of the symbol numbered 10 of the terminal 1. In order to notify the terminal 1 of the symbol position of the transmission resource to be preempted in the downlink data in the slot n, the base station transmits preemption interruption indication Information or preemption indication Information through the PDCCH in slot n +1, the interruption indication Information or preemption indication Information may be, for example, Downlink Control Information (DCI) format (format)2-1, that is, PDCCH with DCI format 2-1, the DCI format includes 14-bit Information, and notifies that data on a symbol with a symbol number of 10 in Reference Downlink Resource (RDR) is affected by a bitmap method, after the terminal 1 receives the preemption/interruption indication Information, it may be determined according to an indication field in the DCI that the transmission resource of the data on the symbol with the symbol number of 10 in the data transmission is preempted or interrupted by other terminals, so that the data on the symbol with the symbol number of 10 at present is not data of its own substantially, then the terminal 1 may discard the data on the symbol during decoding, for example, set the data on the symbol to 0 and then perform overall decoding.

Wherein, the reference downlink resource is defined as: from the first symbol of the control resource set (CORESET) where the DCI format 2_1 was previously detected to the previous symbol of the COREST where the DCI format 2_1 is currently detected in the time domain. As shown in fig. 2, assuming that the first symbol in each slot is the detection position of DCI format 2_1, the reference time domain resource of the downlink resource is the first symbol to the last symbol of slot n. The frequency domain position of the reference downlink resource is an active (active) BandWidth Part (BWP). When using bitmap indication, the reference downlink resource is divided into 14 parts, and the current system supports two divisions { time domain, frequency domain }: 14, 1 or 7, 2, i.e. 14 parts in time domain, 1 part in the whole of the frequency domain, or 7 parts in time domain and 2 parts in frequency domain. Which part of the data is affected can be indicated by 14 bits (bits).

For example, the first symbol in each slot has a transmission opportunity for a PDCCH carrying preemption indication information or interrupting the indication information. In solt n, the base station schedules downlink data transmission on the PDSCH by the terminal 1, where the transmission length of the downlink data of the terminal 1 is 12 symbols, that is, from the symbol numbered 1 to the symbol numbered 13, where the symbol numbered 10 is occupied by URLLC service data of the terminal 2, then the base station transmits DCI format 2-1 through the PDCCH in a transmission opportunity of the PDCCH carrying preemption indication information or interruption indication information, for example, on the first symbol in slot n +1, so as to notify the terminal 1 that the resource transmitted on the symbol numbered 10 is data of other terminals.

The predetermined threshold value pre-agreed by the base station and the terminal is 7, or the predetermined threshold value pre-configured by the base station for the terminal through the configuration signaling is 7.

The terminal 1 may determine, according to the scheduling signaling of the base station, that the transmission length of the downlink data transmitted by the PDSCH in solt n by the terminal 1 is 12 symbols, that is, the transmission length is greater than the preset threshold, and then the terminal 1 may determine that the preemption indication information carried in the PDCCH is valid, so that the terminal 1 may monitor the PDCCH using the DCI format 2-1 in the transmission opportunity of the PDCCH carrying the preemption indication information or interrupting the indication information to receive the interruption indication information or the preemption indication information. For example, if a PDCCH using DCI format 2-1 is monitored in slot n +1, the terminal 1 may preempt the indication information to determine that the data on the symbol with the number 10 is not the data of itself, and when decoding the downlink data transmitted in the PDSCH, the terminal 1 discards the data on the symbol with the number 10 and decodes the data, for example, after setting the data on the symbol with the number 10 to 0, and decodes the received entire data. If the terminal 1 fails in decoding and needs to request retransmission, the data processed according to the interruption indication information or the preemption indication information is stored in a buffer (buffer), so that when the data is combined with a subsequent retransmission version, the damaged part is ensured not to be combined, and error propagation is avoided.

The terminal 2 may also have multiple service types, for example, two service types may exist, one is an eMBB service, and the other is a URLLC service, where the transmission length of the eMBB service may also be longer, and then data of the eMBB service may also be preempted or interrupted by data of a high-priority service of another terminal, so the terminal 2 may also be configured to need to monitor a PDCCH using DCI format 2-1.

Specifically, the terminal 2 knows that the transmission length of the scheduled data transmitted on the PDSCH is 1 symbol according to the scheduling signaling, and if the transmission length is smaller than the preset threshold, the terminal 2 determines that the preemption indication information is invalid, so the terminal 2 can process in any way:

(1) the terminal 2 does not monitor the PDCCH using the DCI format 2-1 in the next transmission opportunity of the PDCCH for carrying the preemption indication information or interrupting the indication information. For example, terminal 2 may not receive the PDCCH using DCI format 2-1 on the first symbol in slot n +1, and thus may not obtain interruption indication information or preemption indication information transmitted through the PDCCH.

(2) Terminal 2 may also monitor the PDCCH using DCI format 2-1 in a transmission opportunity of the PDCCH for carrying the preemption indication information or interrupting the preemption indication information, for example, terminal 2 may receive the PDCCH using DCI format 2-1 on the first symbol in slot n +1, but does not parse the PDCCH, and may not decode the PDCCH, for example.

The 2 nd mode is more suitable for the case that the transmission interval of the PDCCH carrying the preemption indication information or interrupting the preemption indication information is shorter. In this case, when the terminal 2 may not have resolved the PDCCH carrying the scheduling signaling, but has arrived at a transmission opportunity of the PDCCH carrying the preemption indication information or interrupting the indication information, the terminal 2 does not know the transmission length of the scheduled data, and therefore cannot determine whether the preemption indication information or the interruption indication information is valid, and needs to receive the PDCCH carrying the preemption indication information or interrupting the indication information first.

Specifically, if the transmission length of the scheduled data is obtained by parsing after the terminal 2 receives the data, it may be determined that the preemption indication information or the interruption indication information is invalid according to the length and the threshold, and then decoding of the PDCCH carrying the preemption indication information or the interruption indication information may be stopped.

Specifically, if the terminal 2 has not obtained the transmission length of the scheduled data after receiving the PDCCH carrying the preemption indication information or interrupting the indication information, the terminal 2 further needs to further analyze the PDCCH carrying the preemption indication information or interrupting the indication information, for example, perform operations such as decoding on the PDCCH, and during the analysis, the analysis may be stopped when the preemption indication information or the interruption indication information is determined to be invalid by the transmission length of the scheduled data. If the instruction information can be preempted or the instruction information is interrupted only after the PDCCH carrying the instruction information is analyzed, the instruction information can be ignored or the instruction information can be interrupted, that is, the corresponding data transmission is not processed according to the instruction information.

Example two

Referring to fig. 4, the first symbol in each slot has a transmission opportunity of PDCCH carrying preemption indication information or interrupting the indication information. In solt n-2, the base station schedules the terminal 1 to perform uplink data transmission on the PUSCH in solt n through a scheduling signaling, i.e., PDCCH for eMBB, wherein the transmission length of the uplink data of the terminal 1 is 11 symbols, i.e., from the symbol numbered 2 to the symbol numbered 13, and the PUSCH is used for carrying data of an eMBB service, i.e., embbbpusch. The base station schedules the terminal 2 in solt n-1 to perform uplink data transmission on the PUSCH also on the symbol numbered 4 in solt n, the PUSCH of the terminal 2 is used for carrying URLLC, that is, URLLC PUSCH, and if the priority of URLLC is higher than eMMB, the base station will use the PDCCH of DCI format 2-1 to carry interruption indication information, that is, PDCCH with DCI format 2-1, in a transmission opportunity of PDCCH carrying the preemption indication information or interruption indication information, for example, on the first symbol in slot n-1, to notify that there is interruption of other data on the symbol numbered 4 of the terminal 1, and the terminal 1 needs to stop data transmission on the symbol numbered 4, so as to avoid interference on data of the terminal 2.

The terminal 1 may determine, according to the scheduling signaling of the base station, that the transmission length of the downlink data transmitted by the terminal 1 through the PUSCH in the solt n is 11 symbols, that is, the transmission length is greater than the preset threshold, and then the terminal 1 may determine that the interruption indication information carried in the PDCCH is valid, and then the terminal 1 may monitor the PDCCH using the DCI format 2-1 in a transmission opportunity of the PDCCH carrying the interruption indication information or the preemption indication information to receive the preemption/interruption indication information. For example, if a PDCCH using DCI format 2-1 is monitored in slot n-1, terminal 1 may interrupt indication information to determine that symbol No. 4 is interrupted by other data, and may stop data transmission on symbol No. 4 to avoid interference on data of terminal 2.

Specifically, the terminal 2 knows that the transmission length of the scheduled data transmitted on the PUSCH is 1 symbol according to the scheduling signaling, and if the transmission length is smaller than the preset threshold, the terminal 2 determines that the interruption indication information is invalid, so the terminal 2 can process in any manner:

(1) the terminal 2 does not monitor the PDCCH using DCI format 2-1 in a transmission opportunity of the PDCCH carrying the preemption indication information or interrupting the indication information before the PUSCH in solt n. For example, terminal 2 may not receive the PDCCH using DCI format 2-1 on the first symbol in slot n-1, and thus may not obtain preemption/interruption indication information for transmission over the PDCCH.

(2) Terminal 2 may also monitor the PDCCH using DCI format 2-1 in a transmission opportunity of the PDCCH carrying preemption indication information or interrupting indication information before the PUSCH in solt n, for example, terminal 2 may receive the PDCCH using DCI format 2-1 on the first symbol in slot n-1, but does not parse the PDCCH, and may not decode the PDCCH, for example.

The 2 nd mode is more suitable for the case that the transmission interval of the PDCCH carrying the preemption indication information or interrupting the preemption indication information is shorter. In this case, when the terminal 2 may not have resolved the PDCCH carrying the scheduling signaling, and arrives at a transmission opportunity of the PDCCH for carrying the preemption indication information or interrupting the indication information, the terminal 2 does not know the transmission length of the scheduled data, and therefore cannot judge whether the preemption indication information or the interruption indication information is valid, and needs to receive the PDCCH carrying the preemption indication information or interrupting the indication information first.

Specifically, if the transmission length of the scheduled data is not obtained after the terminal 2 receives the PDCCH carrying the preemption indication information or interrupting the indication information, the terminal 2 further needs to analyze the PDCCH carrying the preemption indication information or interrupting the indication information, and during the analysis, the analysis may be stopped until the preemption indication information or the interruption indication information is judged to be invalid by the transmission length of the scheduled data. If the instruction information can be preempted or the instruction information is interrupted only after the PDCCH carrying the instruction information is analyzed, the instruction information can be ignored or the instruction information can be interrupted, that is, the corresponding data transmission is not processed according to the instruction information.

In summary, in the embodiment of the present invention, the terminal may compare whether the transmission length of the first channel in the time domain is equal to the preset threshold to determine whether the first indication information is valid, so that the terminal may perform corresponding processing according to whether the first indication information is valid, thereby avoiding a situation of causing an information transmission error, and improving performance of the communication system. The base station side can also determine the action of the terminal so as to control and schedule the terminal.
