For convenience of understanding, some contents related to the embodiments of the present invention are explained below:

control resource set (CORESET) # 0.

The time-frequency resource location of CORESET #0 is indicated by a Master Information Block (MIB) message and is determined by table lookup.

For the CORESET multiplexing mode 1, the listening period of CORESET #0 is fixed to 20ms (two radio frames long). The beam of CORESET #0 is associated with a Synchronization Signal and PBCH block (SSB) beam Quasi co-location (QCL). CORESET #0 corresponding to one SSB is arranged in two consecutive slots in a 20ms period. The multiplexing mode 1 is fixed for the Frequency Range (FR) 1.

The multiplexing relationship between the CORESET #0 of the different SSB associations is indicated by parameter M of searchSpacezero in pdcch-ConfigSIB 1. Taking four SSBs as an example, the following cases are included:

when M is 0.5, the multiplexing relationship is as shown in fig. 2;

when M is 1, the multiplexing relationship is as shown in fig. 3;

when M is 2, the multiplexing relationship is as shown in fig. 4.

After determining the time-frequency configuration of the core set #0, the ordinary terminal or the terminal device implemented according to the requirements of the Rel15/Rel16 tries to receive the core set #0 in the corresponding time slot, and after detecting the needed DCI, receives corresponding Information, such as a System Information Block (SIB) 1, according to the DCI indication Information. A Physical Downlink Shared Channel (PDSCH) is received by default in the same time slot.

The reduced capability terminal (RedCap UE) has a reduced capability of receiving CORESET #0 due to the reduced number of receive antennas, and is more likely to fail in single slot detection. Therefore, an enhanced scheme for CORESET #0 reception needs to be designed for simplifying the capability terminal, and more CORESET #0 time-frequency resources (cross-slot or cross-CORESET) are occupied. There is a conflict between the CORESET #0 extension and CORESET #0 multiplexing. As shown in fig. 3, for example, when M is 1, the time-frequency resource of core set #0 in one timeslot may be multiplexed simultaneously corresponding to two SSBs. When the CORESET #0 is extended, two SSBs need to occupy more CCEs respectively, so that collision may occur on the multiplexed time-frequency resources.

Optionally, the PDSCH scheduled by CORESET #0 also needs to be enhanced accordingly, such as repeated transmission or a lower Modulation and Coding Scheme (MCS). These methods require more time-frequency resources to be occupied. Within the narrower system bandwidth or limited initial BWP of the reduced capability terminal, only one SSB associated core set #0 may be supported for scheduling at a time. Different CORESET #0 needs to compete for the use of limited time-frequency resources.

The control information receiving method of the application is provided for the purpose.

The following describes in detail a control information receiving method provided in the embodiments of the present application with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 5, fig. 5 is a flowchart of a method for receiving control information according to an embodiment of the present application, where the method is applied to a terminal, and as shown in fig. 5, the method includes the following steps:

step 501, determining parameters of a first transmission mode;

step 502, detecting target control information according to the parameters of the first transmission mode;

The control information receiving method provided in this embodiment may be applied to a first type of terminal, and may also be applied to a second type of terminal. Wherein, the first type terminal can be understood as a simplified capability terminal. The second class of terminals may be understood as generic terminals, e.g. terminals as defined by Rel15 or Rel 16. For the second class of terminals, the plurality of control resource sets may be received in a specific state by using the first transmission method. The specific state may be entry into power save mode or failure to successfully receive CORESET #0 according to Rel15/Rel16 protocol flow.

Optionally, in the DCI transmission method of this embodiment, the terminal starts to receive the multiple control resource sets according to the first transmission method of this embodiment when one of the following conditions is satisfied:

condition 1, after completing the synchronization process or executing the process of acquiring the system message for the first type of terminal;

condition 2, when the second type of terminal receives a request for executing the flow of the embodiment of the application from the network configuration information;

and condition 3, for the second type of terminal, after the system message acquisition fails or the downlink signal strength is lower than the strength required by the network, and when the current access cell supports the first transmission mode of this embodiment.

The first transmission mode can be understood as CORESET #0 enhanced transmission. The at least two control resource sets may include CORESET #0, and may also include other types of CORESET in a network configuration. It should be noted that the at least two control resource sets may represent control resource sets transmitted by different SSBs in the same first transmission period at corresponding monitoring occasions, or may be the same control resource sets transmitted by different monitoring occasions in the same first transmission period.

The above T is used to indicate a time length of a time unit, which is equal to a time length of a transmission period of the control resource set. The above-mentioned N time units T of the first transmission period may be understood as the time length of the first transmission period is N × T. For example, in one embodiment, the transmission period T of the CORESET #0 is 20ms, and the first transmission period is 20ms × N.

Optionally, in an embodiment, the determining the parameter of the first transmission mode includes:

The target control information may be DCI, that is, in this embodiment, a plurality of CORESET #0 respectively carry a copy or a portion of DCI.

And the target control information transmitted in the control resource set according to the first transmission mode and a first SSB satisfy a quasi co-location relationship, wherein the first SSB is an SSB searched by the terminal.

The first SSB described above can be understood as: the SSBs searched by the terminal in the initial access phase or the best SSBs determined by the last SSB scanning operation are not further limited herein. For a network device, the first SSB may be understood as any SSB sent by the network device.

The time offset may be understood as an offset from a specific reference point, which may be a slot of the SSB0 or a boundary of a SIB update cycle, etc., and is not further limited herein.

The above control resource set can be understood as a resource control set carrying target control information. Specifically, the set of resource control sets may include the aforementioned CORESET #0 and/or CORESET configured by the network to have a quasi-co-location relationship with the SSB. In this embodiment, the sending period of the control resource set is extended, so that resource collision between the core sets #0 associated with different SSBs when the target control information is transmitted according to the first transmission mode can be avoided. Meanwhile, the conflict with the SSB quasi-co-located target PDSCH resource can be avoided, wherein the target PDSCH resource is the PDSCH resource scheduled by the target control information.

Optionally, in the first transmission cycle, the value of N is agreed by a protocol, or indicated by a network device.

Wherein, the mode of the network device indicating the value of N comprises at least one of the following:

the value of N is indicated explicitly through first indication information;

and indicating implicitly through third indication information, where the third indication information is used to indicate a Control Channel Element (CCE) number of the Control resource set in each timeslot.

In this embodiment, N may be understood as a period extension parameter for controlling the resource set. In an embodiment, the indication may be performed through a reserved field in the PBCH, for example, a field in the MIB message.

In another embodiment, a protocol may define or a network device may configure a time domain configuration parameter for controlling the resource set, determine the time domain configuration parameter through an indication of a preset table, and then perform implicit indication through second indication information, or calculate a corresponding value of N through the time domain configuration parameter. In this embodiment, the preset table is provided with values of the parameter N, and examples of the preset table are as follows:

as shown in the above table, the second indication information is used to indicate an index value in the table. For example, the indication index value is 2, the corresponding value of N is 2, the indication index value is 3, and the corresponding value of N is 4. And M is used for indicating the multiplexing relation among the control resource sets corresponding to different SSBs. The second indication information may be understood as a value used for indicating M, and a value of N is related to a value of M, and a corresponding value of N is derived through the value of M.

The third indication information may be understood as a controlResourceSetZero in pdcch-ConfigSIB1 parameter in the MIB message or as a time-frequency resource configuration parameter in a timeslot in the CORESET configuration message, and a value of N may be determined according to the number of CCEs in a control resource set in each timeslot. Specifically, it may be ensured that the number of CCEs of the CORESET #0 resource reaches a certain threshold, where the threshold represents the minimum number of CCEs required to be occupied by the first transmission mode.

Optionally, in this embodiment of the application, the value of the indication N may also be combined according to at least two of the three manners of indicating the value of the N.

In the embodiment of the present application, determining the time offset according to the SSB numbers may be understood as that all candidate SSBs are divided into N groups according to the numbers, and the control resource sets corresponding to the j +1 th group SSBs are sequentially sent in the j +1 th T time period in the period T × N, where j belongs to {0,1, … N-1 }. Wherein, the grouping mode of each SSB may be any one of the following:

In other embodiments, all SSBs may be divided into the same SSB group, that is, the j +1 th group, and at this time, the control resource set of the first transmission method corresponding to each SSB is transmitted in the j +1 th T time slot in the first transmission cycle T × N.

wherein, the first SSB is the SSB searched by the terminal.

Wherein, the time offset is determined by the number of the first SSB and the N, which is understood to mean that the number of the first SSB and the N determines the time offset corresponding to the first SSB. For example, in one embodiment, the time offset may be determined from the result of mod (i, N), i being the number of the first SSB. Specifically, when mod (i, N) ═ j, the control resource set corresponding to the first SSB is transmitted in the j +1 th T period.
