Description

Detection method of downlink channel, configuration method of information, terminal and network equipment
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method for detecting a downlink channel, a method for configuring information, a terminal, and a network device.
Background
In the current 5G system, the number of PDCCH (physical downlink control channel) candidates, aggregation level and monitoring period included in the search space can be configured by the network side. Within one active BWP (active bandwidth part) at most 10 different search spaces are supported. After receiving the relevant configuration of the network side, the terminal needs to detect the downlink control channel in the corresponding search space according to the configured SS (search space) period. That is, the terminal attempts to detect DCI on each PDCCH candidate in the search space according to the DCI format (downlink control information format) desired to be received.
In the 5G mobile communication system, in order to support different types of services, the terminal needs to detect and receive the downlink control channel very densely. The frequent detection and reception of the downlink control channel will undoubtedly increase the complexity of the terminal side and greatly increase the power consumption of the terminal side. The network side can reduce the size of the search space and increase the search space listening period in a configuration mode. Due to uncertainty of service arrival, the base station does not send the PDCCH at the monitoring position corresponding to each configured search space, and the high-level signaling configuration period is long, which may reduce the scheduling flexibility of the network side. In addition, the terminal side needs to monitor according to the configuration all the time, thereby increasing the power consumption of the terminal side.

Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
As shown in fig. 1, an embodiment of the present invention provides a method for detecting a downlink channel, which is applied to a terminal, and the method includes:
step 11, obtaining the corresponding relation between the resource position where the DCI (downlink control information) of the terminal is transmitted and the detection mode of the downlink control channel; here, the correspondence between the resource location where the DCI of the terminal is transmitted and the detection mode of the downlink control channel may be obtained through a higher layer signaling or a predefined mode. Here, higher layer signaling, such as RRC (radio resource control) signaling, but not limited to RRC signaling;
and step 12, detecting the downlink control channel according to the corresponding relation between the resource position and the detection mode of the downlink control channel.
In the embodiment of the invention, the corresponding relation between the resource position of the DCI transmission of the terminal and the detection mode of the downlink control channel is obtained; and detecting the subsequent downlink control channel according to the corresponding relation between the resource position and the detection mode of the downlink control channel. The method can avoid defining a new information domain in the DCI, reduce the complexity of the terminal for blind detection of the downlink control channel and reduce the power consumption of the terminal.
In an embodiment of the present invention, a correspondence between the resource location and a detection method of a downlink control channel includes at least one of:
1) a correspondence between an SS (search space) ID and a downlink control channel detection mode;
2) and (3) correspondence between CORESET (control resource set) ID and downlink control channel detection mode.
In an embodiment of the present invention, when there is a corresponding relationship between the search space ID and the downlink control channel detection method, an implementation manner of the step 12 includes:
step 121, if the terminal detects the downlink control information DCI for scheduling data transmission in the configured search space # n, the terminal detects the downlink control channel only in the search space # n after completing the data transmission;
step 122, after the terminal detects the DCI for scheduling data transmission in the search space # n again, the terminal detects downlink control channels in all configured search spaces; n is an integer greater than or equal to 0.
Step 123, after the terminal detects the DCI for scheduling data transmission in the search space # n again, the terminal detects the downlink control channel only in the search space # n; and so on.
For example, as shown in fig. 2, it is assumed that a network device (e.g., a base station) configures M ═ 3 search spaces { SS #1 SS #2 SS #3} for a terminal, and has different listening periods, for example, the listening period of SS #1 is T1 ═ 5, the listening period of SS #1 is T2 ═ 1, and the listening period of SS #1 is T3 ═ 2. The base station informs the terminal through RRC signaling, and SS #1 is used to indicate the skip information of the downlink control channel. That is, if the terminal detects that the corresponding scheduling information is received in SS #1, the terminal determines the corresponding downlink control channel skipping behavior. For example, if the terminal detects that DCI is received for the first time in SS #1, the terminal does not detect SS #2 and SS #3 after detecting that DCI is received, but only detects and receives a downlink control channel in SS # 1; subsequently, if the terminal detects the reception of DCI again in SS #1, all the configuration search spaces, that is, { SS #1 SS #2 SS #3}, are detected from that time. Therefore, the terminal does not frequently detect the downlink control channel any more, the power consumption can be reduced, and the complexity of terminal blind detection is reduced.
For the base station side, in order to guarantee the same understanding as the terminal side, it is necessary to perform a corresponding action after receiving an explicit ACK/NACK transmitted by the terminal. For example, for DCI and corresponding data channel, the base station side considers that the monitoring behavior of the downlink control channel is reversed after detecting reception of ACK/NACK. For example, after receiving the first ACK/NACK of the data channel for transmitting DCI scheduling in SS #1, the base station determines that only the downlink control channel is to be transmitted in SS #1, but not the downlink control channels are to be transmitted in SS #2 and SS #3 in the subsequent time period; after receiving the second valid ACK/NACK of the data channel for transmitting DCI scheduling in SS #1, the base station determines that the downlink control channel can be transmitted in SS #1/SS #2/SS #3 in a subsequent time period. And so on. It can be seen that the base station transmits DCI only in SS #1 when it is necessary to change the downlink control channel sensing behavior.
In an embodiment of the present invention, when there is a correspondence between a control resource set CORESET ID and a downlink control channel detection method, another implementation manner of the step 12 includes:
step 221, if the terminal detects that the downlink control information DCI for scheduling data transmission is received in the configured CORESET # m, the terminal detects a downlink control channel in a search space configured in the CORESET # m after the data transmission is completed; the CORESET # m is used for indicating skipping information of a downlink control channel;
step 222, after the terminal detects the DCI for scheduling data transmission in the CORESET # m again, the terminal detects the downlink control channel in all configured search spaces; m is an integer greater than or equal to 0;
step 223, after the terminal detects the DCI for scheduling data transmission in the CORESET # m again, detecting the downlink control channel only in the CORESET # m; and so on.
For example, as shown in fig. 3, the base station may configure a CORESET ID for indicating the downlink control channel skip information through high-layer signaling. It should be noted that one CORESET may configure multiple search spaces. For example, the base station configures two CORESET { CORESET #1 CORESET #2} for the terminal, and CORESET #1 is used to indicate the skip information of the downlink control channel. For example, the terminal detects that DCI is received for the first time in the CORESET #1, after detecting that DCI is received, the terminal does not detect and receive the downlink control channel from the CORESET #2 any more, but only detects and receives the downlink control channel in the CORESET # 1; subsequently, if the terminal detects reception of DCI again in CORESET #1, all downlink control channels in CORESET are detected from that time. Therefore, the terminal does not frequently detect the downlink control channel any more, the power consumption can be reduced, and the complexity of terminal blind detection is reduced. It should be noted that a plurality of associated search spaces may be configured in each core set, and at this time, when the terminal detects that DCI is received for the first time in at least one search space in the core set #1, after detecting that DCI is received, the terminal does not detect a reception downlink control channel from the core set #2 any more, but detects a reception downlink control channel only in the core set # 1.
In an embodiment of the present invention, another implementation manner of the step 12 includes:
step 331, after the terminal detects and receives the downlink control information in the preset search space or the preset CORESET and completes the corresponding data transmission process, the terminal does not detect the downlink control channel any more in T1 time units or only detects the downlink control channel in the preset search space or the preset CORESET; t1 is an integer greater than or equal to 1, and T1 is configured by higher layer signaling or determined by a predefined manner.
For example, the network side configures a search space ID or a CORESET ID for carrying downlink control channel skip information through higher layer signaling (RRC signaling). After detecting that the scheduling information is received in the search space or the core set, the terminal does not monitor any downlink control channel in the following time period T1, or monitors the downlink control channel only in the specific search space/core set. The time T1 is configured by higher layer signaling, such as RRC signaling.
In an embodiment of the present invention, when there is a corresponding relationship between the search space ID and the downlink control channel detection method, another implementation manner of the step 12 includes:
step 441, detecting a physical downlink control channel for scheduling data transmission on the number of the target physical downlink control channel PDCCH candidate in the preset search space, and detecting the downlink control channel according to the corresponding relationship between the number of the PDCCH candidate and the preset skip information.
Optionally, if the terminal detects the DCI of the scheduling data transmission in the PDCCH candidate number # L under the preset Aggregation Level (AL) of the preset search space, the terminal does not detect the DCI within the target time length after completing the transmission of the scheduling data; l is an integer greater than or equal to 0, the target duration includes T2 slots respectively corresponding to one PDCCH candidate number, T2 is an integer greater than or equal to 1; or, the target duration is applied to at least one search space corresponding to one PDCCH candidate number.
For example, the base station specifies a search space ID for indicating downlink control channel skip information through RRC signaling. Then, the correspondence between PDCCH candidate index (index of candidate number) and PDCCH monitoring skip period for each aggregation level in the search space is notified. For example, the search space has 4 aggregation levels { AL1 AL2 AL4 AL8}, and assuming that there are two types of { T21, T22} of the skip period, the corresponding relationship between the PDCCH candidate index and the PDCCH monitoring skip period at each aggregation level is shown in the following table, which is only an example of this embodiment of the present invention and is not intended to limit the scope of this embodiment;
Figure BDA0002055922380000111
the base station selects the PDCCH candidate index for transmitting the PDCCH at the specific AL according to the power saving requirement of the terminal, and the PDCCH candidate index is not limited to the above 0 and 1, and may include more PDCCH candidate indexes. It should be noted that if the terminal does not detect any DCI reception in the search space specified by the base station, the terminal needs to monitor the downlink control channel in all configured search spaces.
In the above embodiments of the present invention, all or part of the search space, the CORESET, the PDCCH candidate index, T1, and T2(T21 or T22) in which the terminal detects that the scheduling information is received may also be determined in a predefined manner.
In the embodiment of the invention, the PDCCH monitoring skipping time period is determined in an implicit mode, and the terminal determines to skip part of monitoring of the search space according to the defined rule, so that the condition that a new information domain is defined in the DCI can be avoided, the complexity of terminal blind detection is reduced, and the power consumption of the terminal is reduced.
Further, the base station determines the corresponding relationship between the PDCCH candidate and the ID of the search space to be skipped through a high-level signaling (RRC signaling) configuration or a protocol predefined manner, and the base station side and the terminal side determine the corresponding skipping behavior according to the candidate number of the PDCCH. An example is shown in the following table, note that one PDCCH candidate number may correspond to a set of search spaces. Suppose that the base station configures 3 SSs and carries the downlink control channel skip information in SS # 1.
