Description

Information detection, transmission, processing and receiving method, terminal and network equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information detection, transmission, processing, and receiving method, a terminal, and a network device.

Background

In the current NR (new air interface) system, the maximum blind detection number of a terminal in a time slot is constrained based on a subcarrier interval (μ), and specifically, if the blind detection number configured by a network side for the terminal exceeds the blind detection number as specified in table 1, the terminal may reduce the blind detection number according to a certain criterion so as not to exceed the maximum blind detection number defined by the terminal capability.

TABLE 1

The terminal needs to detect the downlink physical channel to obtain corresponding scheduling information or transmission indication information. Specific scheduling information is acquired by detecting PDCCH (Physical Downlink Control Channel ) candidates. Specifically, a set of candidate locations (set of PDCCH candidates) that the terminal needs to detect is defined by a search space (PDCCH search spaces). The search space comprises a public search space and a user-specific search space.

For downlink control information DCI, specific detection configuration is implemented based on configuration of the search space. Specifically, the configuration of the search space includes the following information:

1) ID (search Space Id) of the search space.

2) The set of control resources ID (control Resource Set Id) where the search space resides.

3) The detection period and offset of the search space (monitoring Slot Periodicity And Offset).

4) The search space is symbol position (monitoring Symbols Within Slot) within a slot.

5) The corresponding number of Candidates (nrofcandidates) within each aggregation level

6) Search space type (search Space Type): in particular comprises configuring the search space as a Common Search Space (CSS) or a user-specific search space (USS)

a) In case of CSS, the terminal needs to be configured to detect whether or not the following DCI Formats (DCI Formats) are detected: DCI formats0_0 and 1_0,DCI formats 2_0,DCI formats2_1,DCI formats 2_2,DCI formats 2_3.

If the sizes of DCI formats0_0 and 1_0 are identical, only 1 blind detection is needed, and specifically, whether the detected DCI is DCI formats0_0 or 1_0 can be determined according to a field in the DCI format. If the DCI formats 2_2 and 2_3 are identical to the DCI formats0_0 in size, 1 blind detection is required, and specifically, it is possible to determine which DCI format the detected DCI is based on the CRC scrambling of the DCI formats.

The sizes of DCI formats 2_0 and DCI formats2_1 are configured based on RRC signaling, and thus may not be consistent with the sizes of DCI formats 2_2/DCI formats2_3/DCI formats 0_0/DCI formats1_0, and thus the number of blind detection of the terminal may be increased.

b) If USS, then it is necessary to configure whether the user detects formats0-0 and formats1-0, or formats0-1 and formats1-1. If the network configuration user is detecting formats0-0 and formats1-0, then 1 candidate based on 1 aggregation level only needs to be blindly detected 1 time for the 2 formats due to the consistent size; while formats0-1 and formats1-1, if different in size, require blind detection 2 times for 2 formats based on 1 candidate for 1 aggregation level.

Based on the above configuration, the detection process of the terminal for the downlink control channel in one slot can be described as follows: and judging the number N of the search spaces in the time slot, and judging the specific configuration of each search space. And judging the blind detection times in the time slot according to the specific configuration of the search space. If the maximum blind detection times of the terminal are exceeded, the required blind detection times are reduced according to a certain rule, the power consumption and the processing complexity of the terminal are increased, and the processing time of the terminal is wasted.

Detailed Description

In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, an embodiment of the present invention provides an information detection method, which is applied to a terminal, and includes:

step 11, detecting downlink control information in a time unit, and stopping detecting downlink control information scheduled for a target service in the time unit or stopping detecting downlink control information in other preset formats scheduled for the target service in the time unit when N downlink control information scheduled for the target service and having a preset format are detected; wherein N is a positive integer greater than or equal to 1.

In this step, N is predefined, which may be predefined by the terminal or may be predefined by the network device, and is not specifically limited herein. It should be noted that, the setting of N needs to be less than or equal to the maximum number of blind tests supported by the terminal in the time unit.

Wherein, the other preset formats specifically refer to other formats of the DCI except the preset formats.

In order to reduce the complexity of detecting downlink control information in one time by the terminal, the embodiment of the invention limits the implementation mode of the downlink control information which can detect or process N pieces of downlink control information which are scheduled for the target service and have the format of a preset format in one time unit to the maximum extent, wherein the implementation mode comprises the following steps:

and detecting the downlink control information in one time unit, and stopping detecting the downlink control information scheduled for the target service in the time unit when N downlink control information scheduled for the target service and having the format of a preset format are detected.

For example, assuming that n=1, when the target service is a downlink service, after successfully detecting 1 downlink control information in the format of DCI format 1_1 or DCI format 1_0 for scheduling the downlink service in one time unit, the terminal stops detecting the downlink control information for scheduling the downlink service in the time unit.

For another example, assuming that n=1, when the target service is an uplink service, after successfully detecting 1 downlink control information in the format of DCI format 0_1 or DCI format 0_0 for scheduling the uplink service in one time unit, the terminal stops detecting the downlink control information for scheduling the uplink service in the time unit.

Further, the embodiment of the present invention also provides a method for reducing the complexity of detecting downlink control information in a time by a terminal, which specifically includes:

and detecting the downlink control information in one time unit, and stopping detecting the downlink control information of other preset formats for scheduling the target service in the time unit when N downlink control information which is scheduled for the target service and has the preset format is detected.

For example, assuming that n=1, when the target service is downlink service, after successfully detecting 1 downlink control information of DCI format 1_1 or DCI format 1_0 as a format for scheduling the downlink service in one time unit, the terminal stops detecting downlink control information of other preset formats (other preset formats refer to other formats except DCI format 0_1 or DCI format 0_0) for scheduling the target service in the time unit.

For another example, assuming that n=1, when the target service is an uplink service, after successfully detecting 1 downlink control information of DCI format 0_1 or DCI format 0_0 as a format for scheduling the uplink service in one time unit, the terminal stops detecting downlink control information of other preset formats (other preset formats refer to other formats except DCI format 0_1 or DCI format 0_0) for scheduling the target service in the time unit.

Further, in the above embodiment of the present invention, the method further includes:

For the second mode, in the embodiment of the present invention, when the terminal stops detecting the downlink control information of other preset formats for scheduling the target service in the time unit, the terminal continues to detect the downlink control information of the preset formats for scheduling the target service in the time unit.

For example, assuming that n=1, when the target service is a downlink unicast service, the terminal successfully detects downlink control information for scheduling the downlink unicast service in one time slot, where the downlink control information is carried based on DCI format 1_0, and the terminal does not detect downlink control information for scheduling the downlink unicast service for other DCI formats except DCI format 1_0; on the other hand, when the terminal continues to detect the downlink control information scheduled for the downlink unicast service in the slot, only the downlink control information scheduled for the downlink unicast service carried by the DCI format 1_0 is detected.

For another example, assuming that n=1, when the target service is a downlink unicast service, the terminal successfully detects downlink control information for scheduling the downlink unicast service in one time slot, where the downlink control information is carried based on DCI format 1_1, and the terminal does not detect downlink control information for scheduling the downlink unicast service for other DCI formats except for DCI format 1_1; on the other hand, when the terminal continues to detect the downlink control information scheduled for the downlink unicast service in the slot, only the downlink control information scheduled for the downlink unicast service carried by the DCI format 1_1 is detected.

For another example, assuming that n=1, when the target service is an uplink unicast service, the terminal successfully detects downlink control information for scheduling the uplink unicast service in one time slot, where the downlink control information is carried based on DCI format 0_0, and the terminal does not detect downlink control information for scheduling the downlink unicast service for other DCI formats except DCI format 0_0; further, when the terminal continues to detect downlink control information for scheduling uplink unicast traffic in the time slot, only downlink control information for scheduling uplink unicast traffic carried by DCI format 0_0 is detected.

For another example, assuming that n=1, when the target service is an uplink unicast service, the terminal successfully detects downlink control information for scheduling the uplink unicast service in one time slot, where the downlink control information is carried based on DCI format 0_1, and the terminal does not detect downlink control information for scheduling the uplink unicast service for other DCI formats except DCI format 0_1; further, when the terminal continues to detect downlink control information for scheduling uplink unicast traffic in the time slot, only downlink control information for scheduling uplink unicast traffic carried by DCI format 0_1 is detected.

Further, in the above embodiment of the present invention, the downlink control information is carried on a physical downlink control channel PDCCH.

Preferably, one time unit includes K1 slots, or one time unit includes K2 symbols; k1 and K2 are positive integers. For example, one time unit includes 1 slot, or one time unit includes 8 symbols, or the like.

Further, the target service includes: downstream traffic and/or upstream traffic. And the downlink service at least comprises a downlink unicast service; the uplink traffic includes at least uplink unicast traffic.

In the embodiment of the present invention, a plurality of DCI formats (DCI formats) shown in table 2 are defined for different downlink control information (Downlink Control Information, DCI):

TABLE 2

Further, in the above embodiment of the present invention, as can be seen from table 2, in the case that the target service is a downlink service, the preset format includes: downlink control information DCI format 1_0 or DCI format 1_1; in the case that the target service is an uplink service, the preset format includes: DCI format 0_0 or DCI format 0_1.

In summary, the information detection method provided by the embodiment of the present invention reduces the blind detection times of the terminal in a time unit by limiting the number and/or format of the detected downlink control information of the terminal on the premise that the maximum blind detection times supported by the terminal are not exceeded, so as to reduce the complexity of the terminal, improve the processing time of the terminal and reduce the processing power consumption of the terminal.

Correspondingly, as shown in fig. 2, an embodiment of the present invention further provides an information transmission method, which is applied to a network device, and includes:

step 21, transmitting downlink control information to the terminal in a time unit;

Preferably, step 21 includes:

transmitting downlink control information to a terminal through a Physical Downlink Control Channel (PDCCH) in a time unit; in other words, the downlink control information is carried on a physical downlink control channel PDCCH.

It should be noted that, in the embodiment of the present invention, a plurality of formats are defined for different downlink control information (Downlink Control Information, DCI), and, similarly, according to table 2, it can be known that in the above embodiment of the present invention, when the target service is a downlink service, the preset format includes: downlink control information DCI format 1_0 or DCI format 1_1; in the case that the target service is an uplink service, the preset format includes: DCI format 0_0 or DCI format 0_1.

In summary, the information transmission method provided in the above embodiment of the present invention reduces the blind detection times of the terminal in a time unit by limiting the number and/or format of the detected downlink control information of the terminal on the premise that the maximum blind detection times supported by the terminal are not exceeded, so as to reduce the complexity of the terminal, improve the processing time of the terminal, and reduce the processing power consumption of the terminal.

Furthermore, the method of directly limiting the terminal to detect or process at most N downlink control information scheduled for the target service in one time unit and having a format of a preset format can effectively reduce the blind detection times of the terminal, but the scheme limits the flexibility of scheduling the terminal by the network device. Specifically, the network device cannot implement that the terminal schedules resources of more than N different uplink time units for transmission in 1 time unit at the same time, and the limitation, especially when TDD (time division duplex) has a uplink-downlink ratio and a downlink-uplink ratio is larger, limits the uplink data rate of the terminal; or, the network device cannot implement that the terminal schedules resources of more than N different downlink time units for transmission at the same time in 1 downlink time unit.

In order to solve the above problem, as shown in fig. 3, an embodiment of the present invention further provides an information processing method, applied to a terminal, including:

step 31, reporting the downlink control information detection capability information of the terminal; the downlink control information detection capability information of the terminal is specifically used for indicating the capability of the terminal to detect or process the downlink control information in a time unit.

wherein M is a positive integer greater than or equal to 1.

It should be noted that, the setting of M needs to be less than or equal to the maximum number of blind tests supported by the terminal in the time unit.

Preferably, the terminal reports the downlink control information detection capability information thereof, informs the network device of the downlink control information detection capability which can be supported by the terminal, and the downlink control information detection capability information can assist the network device in scheduling judgment of the terminal, so that the terminal performance is improved.

For example: the terminal reports the downlink control information detection capability information, and the downlink control information detection capability information indicates that the terminal does not support processing more than M downlink control information for scheduling downlink unicast service in one time slot.

Assuming that m=1, the terminal successfully detects 1 DCI format1_1 or DCI format 1_0 scrambled based on the C-RNTI, and the terminal stops detecting (or is called the terminal no longer detects) the other DCI formats 1_1 or DCI formats 1_0 scrambled based on the C-RNTI. The DCI format1_1 or DCI format 1_0 is used to carry scheduling information for downlink unicast service transmission.

For another example: the terminal reports the downlink control information detection capability information, and the downlink control information detection capability information indicates the terminal to support processing more than M downlink control information for scheduling downlink unicast service in one time slot.

Assuming that m=1, after the terminal successfully detects 1 piece of DCI format1_1 or DCI format 1_0 scrambled based on the C-RNTI, the terminal continues to detect other pieces of DCI format1_1 or DCI format 1_0 scrambled based on the C-RNTI. The DCI format1_1 or DCI format 1_0 is used to carry scheduling information for downlink unicast service transmission.

For another example: the terminal reports the downlink control information detection capability information, and the downlink control information detection capability information indicates that the terminal does not support processing more than M downlink control information for scheduling uplink unicast services in one time slot.

Assuming that m=1, after the terminal successfully detects 1 piece of DCI format 0_0 or DCI format 0_1 scrambled based on the C-RNTI, the terminal stops detecting other pieces of DCI format 0_0 or DCI format 0_1 scrambled based on the C-RNTI. Wherein, the DCI format 0_0 or DCI format 0_1 is used to carry scheduling information for uplink unicast service transmission.

For another example: the terminal reports the downlink control information detection capability information, and the downlink control information detection capability information indicates that the terminal supports processing more than M downlink control information which is scheduled for uplink unicast service in one time slot.

Assuming that m=1, after the terminal successfully detects 1 piece of DCI format 0_0 or DCI format 0_1 scrambled based on the C-RNTI, the terminal continues to detect other pieces of DCI format 0_0 or DCI format 0_1 scrambled based on the C-RNTI. Wherein, the DCI format 0_0 or DCI format 0_1 is used to carry scheduling information for uplink unicast service transmission.

In summary, in the information processing method provided by the embodiment of the invention, the terminal reports the downlink control information detection capability information thereof to inform the network equipment of the downlink control information detection capability which can be supported by the terminal, so as to assist the network equipment in scheduling and judging the terminal and improve the terminal performance; further, the number and/or format of the downlink control information detected by the terminal are limited, and the blind detection times of the terminal in one time unit are reduced on the premise that the maximum blind detection times supported by the terminal are not exceeded, so that the complexity of the terminal is reduced, the processing time of the terminal is prolonged, and the processing power consumption of the terminal is reduced.

Correspondingly, as shown in fig. 4, an embodiment of the present invention further provides an information receiving method, which is applied to a network device, and includes:

step 41, receiving the downlink control information detection capability information reported by the terminal; the downlink control information detection capability information of the terminal is specifically used for indicating the capability of the terminal to detect or process the downlink control information in a time unit.

Step 42, sending downlink control information to the terminal according to the downlink control information detection capability information;

wherein M is a positive integer greater than or equal to 1.

Further, in the case where the downlink control information detection capability information is used to instruct the terminal to not support detection or processing of more than or equal to M downlink control information scheduled for the target service in the time unit, or in the case where the downlink control information detection capability information is used to instruct the terminal to detect or process that the number of downlink control information scheduled for the target service in the time unit is M, the number of downlink control information scheduled for the target service and formatted in a preset format, which is sent by the network device in the time unit, is less than or equal to M.

Preferably, in the case where the downlink control information detection capability information is used to instruct the terminal to support processing of more than or equal to M pieces of downlink control information scheduled for the target service in the time unit, or in the case where the downlink control information detection capability information is used to instruct the terminal to be able to process more than M pieces of downlink control information scheduled for the target service in the time unit, the number of pieces of downlink control information scheduled for the target service and having a format that is preset and is transmitted in the time unit may be more than M, or less than or equal to M, which is not particularly limited herein.

transmitting downlink control information to a terminal through a Physical Downlink Control Channel (PDCCH) according to the downlink control information detection capability information; i.e. the downlink control information is carried on the physical downlink control channel PDCCH.

In summary, in the information receiving method provided by the embodiment of the invention, the terminal reports the downlink control information detection capability information thereof to inform the network equipment of the downlink control information detection capability which can be supported by the terminal, so as to assist the network equipment in scheduling and judging the terminal and improve the terminal performance; further, the number and/or format of the downlink control information detected by the terminal are limited, and the blind detection times of the terminal in one time unit are reduced on the premise that the maximum blind detection times supported by the terminal are not exceeded, so that the complexity of the terminal is reduced, the processing time of the terminal is prolonged, and the processing power consumption of the terminal is reduced.
