detailed description

In the following, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

In 5G NR (New Radio) technology, a user equipment can be configured with multiple PDCCH search spaces. In any search space, the CCE (control channel element) on which the user equipment can blindly detect the PDCCH can be further configured. Control channel unit) aggregation level. Under different aggregation levels, the position of the blind detection PDCCH can be further configured. Since the PDCCH can carry different DCI (Downlink Control Information) formats, different DCI formats can have Different DCI sizes (sizes), so you can also configure the DCI sizes that the user equipment needs to detect.

For example, the user equipment is configured with two search spaces, search space 1 is shown in Table 1, and search space 2 is shown in Table 2:

Table 1

Table 2

Based on the blind detection method in the related art, the user equipment stops blind detection of the PDCCH in two cases. One is when the number of detected DCIs reaches the maximum possible number of DCIs, and there is a one-to-one correspondence between the DCI and the PDCCH. , The number of detected PDCCHs can be determined according to the number of detected DCIs; the second is to traverse all the searchable content in all search spaces.

In this case, the user equipment needs to detect the DCI according to the following process: First, in the search space 1, blind detection is performed on 4 positions with the CCE aggregation level being 1, and when the CCE aggregation level is 2, the blind detection is performed. Perform blind inspection at 2 locations, perform blind inspection at 2 locations if the CCE aggregation level is 4, and need to detect DCI size1 and DCI size2 at each blind location; then in search space 2, aggregate at CCE If the degree is 4, perform blind inspection on 2 positions, if the CCE aggregation degree is 8, perform blind inspection on 1 position, and if the CCE aggregation degree is 16, perform blind inspection on 1 position, and Each blind position needs to detect DCI size3 and DCI size4.

Wherein, when the number of detected DCIs reaches the maximum possible number of DCIs, the blind detection is stopped. For example, the number of detected DCIs in search space 1 reaches the maximum possible number of DCIs. 2 to perform the detection; otherwise, the blind detection is stopped after all the contents to be detected in the two search spaces are detected according to the above process.

However, in most practical cases, the base station transmits the physical downlink control channel with certain tendencies, and DCI is not evenly distributed in the search space, and the search operation performed by the user equipment in the search space does not have a tendency, so it will be missed. The opportunity to end the detection operation as soon as possible by prioritizing the detected DCI results in excessive power consumption.

FIG. 1 is a schematic flowchart of an auxiliary method for detecting a physical downlink control channel according to an embodiment of the present disclosure. The method according to this embodiment is used at a base station side, and the base station may perform the process with a user equipment based on 5G NR Communication, wherein the user equipment may be an electronic device such as a mobile phone, a tablet computer, or a wearable device.

As shown in FIG. 1, the auxiliary method for detecting a physical downlink control channel includes:

In step S11, determining the tendency information of transmitting the physical downlink control channel;

In step S12, the detection order information for detecting the physical downlink control channel is determined according to the tendency information, where the detection order information is used to instruct a user equipment to detect an action order of the physical downlink control channel;

In step S13, the detection sequence information is sent to the user equipment.

In one embodiment, the base station may determine the tendency information of transmitting the physical downlink control channel according to various aspects of information.

For example, the base station itself stores configuration information, and the trend information determined according to the configuration information may instruct the base station to preferentially send DCI at a position with a smaller number. In this case, the detection sequence information determined according to the trend information instructs the user equipment to detect the DCI preferentially on a potential physical downlink control channel transmission position with a smaller number.

For example, the base station can obtain the channel status of the user equipment. If the channel status is poor, the base station preferentially sends the DCI with a higher degree of aggregation determined according to the configuration information. In this case, the detection order information determined according to the trend information instructs the user equipment to preferentially detect DCI by using a higher aggregation degree of CCEs.

It should be noted that, since the relationship between the DCI and the physical downlink control channel is one-to-one, detecting DCI can be equivalent to detecting the physical downlink control channel.

In one embodiment, the dimensions of the physical downlink control channel detected by the user equipment include: search space, the degree of CCE aggregation, the potential physical downlink control channel transmission position, and the size of the downlink control information under the aggregation degree of each CCE. The detection order may indicate one or more of the above four dimensions.

For example, the detection order information is to detect the physical downlink control channels in the order of the indicated search space. The order of the indicated search space is: search space 1, search space 2, and the maximum possible number of DCI is 2. Then, the user equipment may first detect DCI in search space 1, and if two DCIs are detected in search space 1, then the detection may be stopped to avoid preferential detection of power consumption caused by search space 2.

For example, the detection sequence information is to detect the physical downlink control channel in the order of the indicated aggregation degree of the control channel unit, and the indicated order of the aggregation degree of the CCE is: 4, 8, 16, 2, 1, and the largest possible The number of DCIs is two. Then the user equipment can detect in the above two search spaces in the order of the degree of aggregation of the CCEs of 4, 8, 16, 2, 1, 1. If a degree of aggregation of the CCE is 4, a DCI is detected. If a DCI is detected when the aggregation degree is 8, the detection can be stopped, thereby saving power consumption for detecting when the CCE aggregation degree is 16, 2, or 1.

In a case where the detection order information includes multiple dimensions among the above four dimensions, the user equipment may use a dimension with a smaller power consumption required to switch the content among the multiple dimensions as a priority dimension to reduce power consumption.

For example, the detection sequence information includes detecting the physical downlink control channels in the order of the indicated search space, and detecting the physical downlink control channels in the order of the indicated degree of aggregation of the control channel units. The power consumption is less than the power consumption that changes the degree of aggregation of CCEs, then the user equipment takes the search space as a priority dimension, that is, when the degree of aggregation of adjacent CCEs spans the search space, or when the same degree of aggregation of CCEs exists in different search spaces, The search space is preferentially switched to ensure detection in the order of the indicated degree of aggregation of CCEs.

Specifically, for example, the order of the indicated search spaces is: search space 1, search space 2, and the order of the indicated degree of aggregation of CCEs is: 4, 8, 16, 2, 1, and the maximum possible number of DCI is 2 In both search space 1 and search space 2, there is a case where the aggregation degree of CCE is 4; then, DCI can be detected in search space 1 with a CCE aggregation degree of 4, and then in search space 1 in CCE. If the degree of aggregation is 4, DCI is detected. If one DCI is detected in each of the two tests, the detection can be stopped.

Fig. 2 is a schematic flowchart of another auxiliary method for detecting a physical downlink control channel according to an embodiment of the present disclosure. As shown in FIG. 2, the method further includes:

In step S14, the number of physical downlink control channels currently actually transmitted to the user equipment is determined;

In step S15, a quantity of auxiliary information is determined according to the quantity, where the quantity of auxiliary information is used to indicate an actual quantity of physical downlink control channels that the user equipment needs to detect;

In step S16, quantity assistance information is sent to the user equipment.

In one embodiment, when detecting the DCI, the user equipment is based on the maximum possible DCI number, that is, when the detected DCI number reaches the maximum possible DCI number, the detection is stopped. However, the maximum possible number of DCIs is often greater than the number of physical downlink control channels currently transmitted by the base station to the user equipment. This may cause the user equipment to continue detecting operations when it detects all the DCIs currently actually transmitted to the user equipment by the base station. However, in fact, there is no DCI to be detected, which results in a waste of power.

The base station sends quantity auxiliary information to the user equipment to indicate the actual number of physical downlink control channels that the user equipment needs to detect, so that the user equipment stops detecting when the actual number of DCIs is detected, thereby avoiding unnecessary detection. Operation wasting power.

In one embodiment, the base station may carry the quantity of auxiliary information through DCI, where one or more bytes may correspond to the quantity of auxiliary information, for example, two bits in DCI may correspond to the quantity of auxiliary information. If the bit is 00, then the indicated actual quantity is 1. If the two bits are 01, then the indicated actual quantity is 2. If the two bits are 10, then the indicated actual quantity is 3. If the bits are 11, then the actual number indicated is 4.

In one embodiment, the base station may carry quantity auxiliary information through CRC (Cyclic Redundancy Check) scrambling information of DCI, wherein the scrambling information may be C-RNTI (Temporary Identification of Cell Wireless Network), for example, C-RNTI is The actual quantity indicated by 1 is 1, the actual quantity indicated by C-RNTI is 2, the actual quantity indicated by C-RNTI is 3, and the actual quantity indicated by C-RNTI is 4, and the actual quantity indicated by 4 is 4.

Take the base station carrying quantity auxiliary information through DCI as an example. If the actual number indicated is 1, then when the user equipment detects a DCI, the actual number of physical downlink control channels to be detected can be determined by analyzing the DCI. That is, only 1 DCI needs to be detected, and then subsequent detection can be stopped. If the actual number indicated is 2, when the user equipment detects 1 DCI, the actual physical downlink control channel to be detected can be determined by analyzing the DCI. The number is two, that is, two DCIs need to be detected, so that the DCI can continue to be detected, and when the second DCI is detected, the detection is stopped.

In addition, the quantity auxiliary information may also be set in other information in the DCI as required.

Optionally, the actual number is a total amount of downlink control channel messages that the user equipment needs to detect in all search spaces.

In one embodiment, the actual number may be one. In this case, the actual number may be the total number of downlink control channel messages that the user equipment needs to detect in all search spaces. For example, the actual number is 2, and the user The device can detect one by one for multiple search spaces and stop detecting when two DCIs are detected.

Optionally, the actual number includes the number of downlink control channel messages that the user equipment needs to detect in each search space, respectively.

In one embodiment, the actual number may be multiple numbers. In this case, the actual number may be the number of downlink control channel messages that the user equipment needs to detect in each search space, for example, the actual number is 2 and 3, then the user equipment may detect search space 1 first, detect two search spaces 2 when search space 1 is detected, and stop detection when three DCI are detected in search space 2.

Fig. 3 is a schematic flowchart of another auxiliary method for detecting a physical downlink control channel according to an embodiment of the present disclosure. As shown in FIG. 3, the method further includes:

In step S17, determine the last downlink control information sent to the user equipment according to the detection sequence information;

In step S18, the sequence number auxiliary information is determined according to the detection sequence information, where the sequence number auxiliary information is used to indicate whether the downlink control information detected by the user equipment is the last downlink control information;

In step S19, serial number auxiliary information is sent to the user equipment.

In one embodiment, since the base station can instruct the user equipment to detect the PDCCH action sequence through the detection sequence, the base station can determine which PDCCH transmitted to the user equipment is the last PDCCH according to the detection sequence information, that is, to determine the PDCCH transmitted to the user equipment. Which DCI is the last DCI, and the sequence number auxiliary information can be determined according to the detection sequence. The sequence number auxiliary information indicates whether the DCI detected by the user equipment is the last DCI. For example, the sequence number auxiliary information occupies one bit. When the bit is 1, Indicates that the DCI detected by the user equipment is the last DCI. When this bit is 0, it indicates that the DCI detected by the user equipment is not the last DCI.

According to this, the user equipment can determine whether the detected DCI is the last DCI according to the sequence number auxiliary information. When it is determined that the detected DCI is not the last DCI, it can continue to detect, and when it is determined that the detected DCI is the last DCI At this time, the detection can be stopped to avoid wasting power.

In one embodiment, the base station may carry the sequence number auxiliary information through DCI, wherein one or more bytes in the DCI may correspond to the sequence number auxiliary information, for example, one bit in the DCI corresponds to the sequence number auxiliary information, if each bit is 0 , Then it indicates that the DCI where the bit is located is not the last DCI. If the bit is 1, it indicates that the DCI where the bit is located is the last DCI. After the base station determines the last DCI sent to the user equipment according to the detection sequence information, it can indicate that the DCI is the last DCI by using the bits carried by the last DCI.

In one embodiment, the base station may carry sequence number auxiliary information through the CRC scrambling information of the DCI. The scrambling information may be a C-RNTI. For example, a C-RNTI of 1 indicates that the DCI is not the last DCI, and a C-RNTI of 2 Indicates that the DCI is the last DCI. After the base station determines the last DCI sent to the user equipment according to the detection sequence information, it can indicate that the DCI is the last DCI by using the sequence number auxiliary information carried in the CRC scrambling information of the last DCI.

In step S22, a physical downlink control channel is detected according to an operation sequence indicated by the detection sequence information.

In step S23, quantity auxiliary information sent by the base station is received, where the quantity auxiliary information is used to indicate the actual number of physical downlink control channels that the user equipment needs to detect;

In step S24, it is determined whether the detected physical downlink control channel reaches the actual number, and if it reaches the actual number, the detection is stopped.

It should be noted that step S23 can be performed at the same time as step S21, that is, when receiving the detection sequence information, quantity auxiliary information is also received. Correspondingly, step S24 may also be performed at the same time as step S22, that is, the PDCCH is detected based on the two pieces of information: detection order information and quantity auxiliary information.

By receiving the quantity auxiliary information sent by the base station, the actual number of physical downlink control channels to be detected can be determined, which can cause the user equipment to stop detection when detecting the actual number of DCI, thereby avoiding unnecessary detection operations and wasting power.

In one embodiment, the quantity auxiliary information may be included in the DCI. In this case, the user equipment may determine the quantity auxiliary information by parsing the received DCI.

In one embodiment, the quantity of auxiliary information may be included in the cyclic redundancy check scrambling information of the downlink control information. In this case, the user equipment attempts to perform cyclic redundancy on the received physical downlink control channel.
