One PDCCH is formed by aggregating L continuous Control Channel Elements (CCEs), each Aggregation Level (Aggregation Level) corresponds to one search space, the Aggregation Level indicates that one PDCCH is aggregated by several CCEs, and the search space is a PDCCH set to be detected by the UE.

Detailed Description
As described above, the conventional PDCCH transmission method has a problem of low reliability, and cannot satisfy the reliability requirements of the three major scenarios of 5G, especially URLLC scenario.
In order to solve the above problem, an embodiment of the present invention provides a method for sending a physical downlink control channel, in which a base station configures a physical downlink control channel for multiple repeated transmissions, and a user equipment correspondingly receives the physical downlink control channel for multiple repeated transmissions according to the configuration information, and further combines the physical downlink control channel received for multiple repeated transmissions as a receiving result of the physical downlink control channel. The physical downlink control channel can be received for multiple times, and the physical downlink control channels repeatedly received for multiple times are mutually compensated and referenced, so that the receiving reliability of the physical downlink control channel can be improved.
In order to make the aforementioned objects, features and advantages of the embodiments of the present invention comprehensible, specific embodiments accompanied with figures are described in detail below.
Fig. 1 shows a schematic flow chart of a method for receiving a physical downlink control channel in an embodiment of the present invention, and specific steps included in the method are described in detail below with reference to fig. 1, where the method may include the following steps:
step S11: and receiving the configuration information of the base station to the physical downlink control channel.
In a specific implementation, the configuration information includes that the base station configures the physical downlink control channel to transmit with a maximum number of repetitions N, where N is a positive integer and is greater than or equal to 2. In other words, the base station may configure the maximum number of repetitions of a Physical Downlink Control Channel (PDCCH) to be N.
In an embodiment of the present invention, the configuration information may further include: the base station configures a search space corresponding to the physical downlink control channel to be associated with a plurality of CORESETs, one of the CORESETs is used as an original CORESET, and other CORESETs in the CORESETs are mirror images. That is, the base station may configure the PDCCH to repeat at the same PDCCH monitoring time in multiple CORESET.
In detail, when the UE transmits URLLC traffic, the base station may configure the search space of the UE to be associated with a plurality of CORESET, such as CORESET 1, CORESET 2 …, and CORESET n, respectively. Moreover, one CORESET X (n is more than or equal to X and is more than or equal to 1) can be the original CORESET, and the other CORESET can be the mirror image CORESET. In addition, different parameters may be configured for the multiple CORESET, for example, different time domain lengths may be configured, and for example, different mapping relationships between CCEs and Resource Elements (REGs) may be configured.
In another embodiment of the present invention, the configuration information may further include: the base station configures its search space to be associated with a CORESET. That is, when the UE transmits URLLC traffic, the base station can configure its search space to be associated with a CORESET. Accordingly, the base station may configure the PDCCH to repeat at the same PDCCH monitoring time within one CORESET.
Step S12: and correspondingly receiving the physical downlink control channel repeatedly for multiple times according to the configuration information.
In a specific implementation, according to different configuration information, the manner in which the UE repeatedly receives the physical downlink control channel may be different.
For example, when the base station further configures a search space corresponding to the physical downlink control channel to be associated with a plurality of CORESET, and accordingly receives the physical downlink control channel repeatedly for a plurality of times according to the configuration information, the method may be specifically implemented as follows, first in the original CORESET, blind-detecting a physical downlink control channel candidate m according to a search space, then receiving the physical downlink control channel according to a blind-detection result of the physical downlink control channel candidate m, an initial control channel unit index n, and a physical resource corresponding to an aggregation level L, and further when the physical downlink control channel is monitored, confirming the physical downlink control channel candidate m, the initial control channel unit index n, and the aggregation level L, then according to the confirmed physical downlink control channel candidate m, the initial control channel unit index n, and the aggregation level L, and correspondingly repeatedly receiving the physical downlink control channel i for a plurality of times in the mirror image CORESET.
In other words, the UE may only perform blind detection on all PDCCH candidates m within the original CORESET resource according to the definition of the search space, that is, monitor the PDCCH on the physical resource corresponding to the initial CCE index and aggregation level of the PDCCH candidate m. If the UE successfully monitors the PDCCH, it determines the PDCCH candidate index m, aggregation level L and initial CCE index n, and for convenience of description, this monitoring may be referred to as PDCCH repetition 0. And receiving, after the UE successfully monitors the PDCCH, receiving other PDCCH repetitions in the mirror CORESET according to the information.
In a specific implementation, the repeatedly receiving the physical downlink control channel i for multiple times in the mirror image CORESET according to the confirmed physical downlink control channel candidate m, the initial control channel unit index n, and the aggregation level L may include: firstly, confirming a control channel unit index x where the physical downlink control channel repeatedly received for the ith time is located according to the confirmed physical downlink control channel candidate m, the initial control channel unit index n and the aggregation level L; and then repeatedly receiving the physical downlink control channel i in the mirror image CORESET for multiple times according to the control channel unit index x where the physical downlink control channel repeatedly received for the ith time is located.
In an embodiment of the present invention, the UE may execute the step of determining the control channel unit index x where the ith repeatedly received physical downlink control channel is located according to the determined physical downlink control channel candidate m, the initial control channel unit index n, and the aggregation level L according to the following formula (1):
x＝{n+i*(L+offset),….,n+(i+1)*(L+offset)-1}modNCCE,p； (1)
wherein: n denotes the starting control channel element index, the offset denotes the distance between the physical downlink control channel candidate m and the corresponding repeated control channel element, NCCE,pIndicating the number of said control channel elements contained within the current CORESET.
In particular implementations, the offset is configured by the base station higher layer, is a default value, or is implicitly obtained. As for implicit acquisition, it may be that the offset is obtained according to the aggregation level L, i.e., the offset is equal to the aggregation level L.
When the offset is a default value, such as 0, equation (1) may become equation (1 "):
x＝{n+i*L,….,n+(i+1)*L-1}modNCCE,p； (1”)
it should be noted that one search space at least includes aggregation levels, the number of candidate decoding times at each aggregation level, and a set of CCEs included in each candidate decoding. NR supports the resources of the reuse part CORESET at least in the frequency domain.
Therefore, in another embodiment of the present invention, the UE may execute the step of confirming the control channel unit index x where the ith repeatedly received physical downlink control channel is located according to the confirmed physical downlink control channel candidate m, the initial control channel unit index n and the aggregation level L according to the following formula (2):
wherein: l represents the aggregation level, nCIRepresenting a carrier index; n is a radical ofCCE,pRepresents the total number of control channel elements in the core set p,
maximum value, n, representing the physical downlink control channel candidate for which the UE is configured to monitor aggregation level L on all carriersRNTIAnd the scrambled RNTI of the DCI in the current physical downlink control channel is shown. And, for common search spaces
Search space dedicated to UE
Yp,-1＝nRNTI≠0，A0＝39827,A139829, and D65537;
in other words, the UE may receive the physical resource where the repeated PDCCH is located by 2 principles. The first principle is that, within the mirror CORESET, the index x of the CCE where PDCCH repetition i (0< i < N) is located satisfies equation (1).
The second principle is that, within the mirror CORESET, the PDCCH repeats i (0)<i<N) is also determined by a function of the search space, i.e. the PDCCH repetition i is located in the PDCCH candidate i under the aggregation level L in the mirror CORESET, i.e. the PDCCH candidate i
I.e., the calculation of the control channel element index x satisfies equation (2).
In the concrete implementation, when the base station also configures the search space of the user equipment to be associated with a CORESET, the receiving of the physical downlink control channel is repeated correspondingly for a plurality of times according to the configuration information, may include the steps of first blindly detecting the physical downlink control channel candidate m according to the search space, then, according to the blind detection result of the physical downlink control channel candidate m, the initial control channel unit index n and the physical resource corresponding to the aggregation level L, monitoring the physical downlink control channel, and then confirming the physical downlink control channel candidate m, the initial control channel unit index n and the aggregation level L when the physical downlink control channel is monitored, and finally, repeatedly receiving the physical downlink control channel i for multiple times correspondingly according to the confirmed physical downlink control channel candidate m, the initial control channel unit index n and the aggregation level L.
In a specific implementation, the repeatedly receiving the physical downlink control channel i correspondingly for multiple times according to the confirmed physical downlink control channel candidate m, the initial control channel unit index n, and the aggregation level L includes: confirming a control channel unit index x where the physical downlink control channel repeatedly received for the ith time is located according to the confirmed physical downlink control channel candidate m, the initial control channel unit index n and the aggregation level L; and repeatedly receiving the physical downlink control channel i for a plurality of times according to the control channel unit index x where the physical downlink control channel repeatedly received for the ith time is located.
In other words, the UE may blindly detect the PDCCH candidate m according to the definition of the search space, and monitor the PDCCH on the physical resource corresponding to the initial CCE index and aggregation level of the PDCCH candidate m. If the UE successfully monitors the PDCCH, it determines PDCCH candidate index m, aggregation level L and starting CCE index n, which may be referred to as PDCCH repetition 0 for convenience of description. And when the UE successfully monitors the PDCCH, receiving other PDCCH repetitions according to the information.
In a specific implementation, the step of confirming the control channel unit index x where the ith repeatedly received physical downlink control channel is located according to the confirmed physical downlink control channel candidate m, the initial control channel unit index n and the aggregation level L may be executed according to the following formula (3):
x＝{n+i*(L+offset),….,n+(i+1)*(L+offset)-1}modNCCE,p； (3)
wherein: n denotes the starting control channel element index, the offset denotes the distance between the physical downlink control channel candidate m and the corresponding repeated control channel element, NCCE,pThe number of the control channel elements contained in the CORESET is represented.
In particular implementations, the offset is configured by the base station higher layer, is a default value, or is implicitly obtained. In detail, the UE may receive the physical resource where the PDCCH repetition is located by the principle that, within the CORESET, the CCE where the PDCCH repetition i (0< i < N) is located satisfies formula (3).
The implicitly obtained offset may be an offset obtained according to the aggregation level L, i.e., the offset is L. When the offset is a default value, such as 0, equation (3) may become equation (3 "):
{n+i*L,….,n+(i+1)*L-1}modNCCE,p (3”)
in a specific implementation, the base station may configure the PDCCH to repeat at multiple PDCCH monitoring times within one CORESET. That is, when the maximum number of times that the base station configures the PDCCH is N, and correspondingly, the user equipment correspondingly repeatedly receives the physical downlink control channel for multiple times according to the configuration information, the user equipment may be implemented according to the following steps: and the UE blindly detects a search space, and when one physical downlink control channel candidate m is monitored, the UE directly and repeatedly receives the physical downlink control channel at the following (N-1) monitoring moments, and the maximum number of PDCCH repetitions can be N, and the PDCCH repetitions are respectively located at the N PDCCH monitoring moments. Wherein: different physical downlink control channel candidate indexes are adopted at different physical downlink control channel monitoring moments.
In concrete embodimentsIn the implementation, different physical downlink control channel candidate indexes are adopted at different monitoring times of the physical downlink control channel, in detail, that is, when the monitoring time of the physical downlink control channel is i at the first monitoring time and the physical downlink control channel candidate is m, the physical downlink control channel candidate index is adopted
The physical downlink control channel candidate index is used as the physical downlink control channel candidate index of the monitoring time (i +1), and the physical downlink control channel candidate index is adopted
As the listen time (i + k) (0)<k<N) of the physical downlink control channel candidate index.
