FIG. 2 is a schematic flowchart of a transmission method 200 according to an embodiment of the present application. This method can optionally be applied to the system shown in FIG. 1, but is not limited to this. The method includes at least part of the following content.

S210. The network device configures independent TCI (Transmission Configuration Indication) states for at least two resources occupied by the control information, and the control information is transmitted through the configured at least two resources.

Optionally, in this embodiment of the present application, the locations of time domain resources corresponding to all resources occupied by the control information are the same.

Optionally, in the embodiment of the present application, the control information may include but is not limited to at least one of the following: PDCCH and PUCCH (Physical Uplink Control Channel). In the embodiments of this application, PDCCH is used as an example for illustration, and the PUCCH can refer to the example of PDCCH, so it will not be repeated.

Optionally, in this embodiment of the present application, the at least two resources respectively transmit independent and detectable same control information. For example, two resources respectively transmit the same PDCCH, and the two PDCCHs are independent and detectable.

Optionally, in this embodiment of the present application, the at least two resources respectively transmit different parts of the same control information. For example, two resources respectively transmit different parts of the same PDCCH, and these two parts constitute the complete PDCCH.

Taking the control information as the PDCCH as an example, in the repetition (repetitive) transmission of the PDCCH through multiple TRPs, each TRP has a TCI state, and different TRPs have different TCI states. In this case, you can configure the transmission mode of control information as the FDM transmission mode, and configure the independent TCI state (TCI state) of at least two resources occupied by the PDCCH, which can clarify that multiple TRPs are transmitted using FDM Way. Among them, FDM is a multiplexing technology that modulates multiple baseband signals to different frequency carriers and then superimposes them to form a composite signal.

In the embodiment of the application, the network device configures at least two independent TCI resources occupied by the control information, so that when the control channel is transmitted through multiple TRPs, the transmission mode can be clarified, so that the terminal device can correctly control the control channel. The channel is demodulated. For example, in the case of repetition transmission of the PDCCH through multiple TRPs, the manner of repeated transmission is clarified so that the terminal device can correctly demodulate the candidate PDCCH.

Optionally, in this embodiment of the present application, at least two resources belong to resources occupied by the same candidate control channel configured by the network device for the terminal device.

Optionally, in the embodiment of the present application, the candidate control channel may include but is not limited to at least one of the following: PDCCH and PUCCH.

In an example, the control information is PDCCH, and the candidate control channel is the candidate PDCCH. The frequency domain resources occupied by the PDCCH configured by the network device may constitute the frequency domain resources of the candidate PDCCH.

Network equipment is used for PDCCH transmission by configuring CORESET (Control Resource Set) and search space (Search Space). The control resource set includes multiple physical resource blocks in the frequency domain, and can include 1 to 3 OFDM (Orthogonal Frequency Division Multiplexing) symbols (symbols) in the time domain, and can be located in the time slot. Anywhere. The time domain resources occupied by CORESET are semi-statically configured by high-level parameters. The search space is a collection of PDCCH candidates (PDCCH candidates) under one or more aggregation levels. The aggregation level of the PDCCH actually sent by the base station changes with time. Since there is no related signaling to inform the UE (User Equipment, terminal equipment), the UE needs to blindly detect the PDCCH under different aggregation levels. Among them, the PDCCH to be blindly detected is called a candidate PDCCH. The UE decodes all candidate PDCCHs in the search space. If the CRC (Cyclic Redundancy Check, cyclic redundancy check) check is passed, the content of the decoded PDCCH is considered to be valid for the UE and obtained by decoding Information for follow-up operations.

In NR (New Radio), in each downlink BWP (Bandwidth Part, part of the bandwidth) of each serving cell, the network device can configure up to 10 search space sets for users, and the search space set is configured with The time domain configuration information is used to instruct the user to detect the time domain position of the PDCCH. In addition, the network device configures a set-associated CORESET ID for each search space set, and the user can obtain the physical resources of the search space set in the frequency domain through the CORESET ID. Each search space collection has a unique associated CORESET ID. Different search space sets can be associated with the same CORESET ID. The UE determines the time-frequency domain position of the PDCCH candidate (PDCCH candidate) according to the time domain given by the search space set, the frequency domain of the associated CORESET ID, and other parameters in the search space set.

When the network device configures CORESET, it configures one or a group of TCI state for each CORESET. The TCI state is used to indicate the channel filter corresponding to the user during the demodulation detection of the PDCCH candidate of the Search Space associated with the CORESET. parameter. When a network device configures a set of TCI states for a CORESET, the network device will activate a unique TCI state for the CORESET through MAC CE signaling, which is used to indicate the channel filtering parameters of the UE when demodulating the PDCCH.

In addition, the network device also configures a higher layer index for each CORESET to indicate whether it is the same TRP. The range of this value is 0 and 1. For CORESET configured with the same higher layer index, users think that this is data from the same TRP.

Optionally, in this embodiment of the application, the resource of the candidate control channel includes a group of CCEs (Control Channel Element) configured by the network device, and each CCE in the group of CCEs is in the candidate control channel. There is a unique index in the resource. For example, each CCE in a group of CCEs has a unique index in the resources of the candidate PDCCH: CCE0, CCE1, CCE2, ... etc.

In the embodiment of the present application, the CCE is the basic unit constituting the PDCCH and occupies 6 REGs (Resource Element Group, resource element group). The 6 REGs can be 6 REGs on 1 OFDM symbol, 3 REGs on 2 OFDM symbols, or 2 REGs on 3 OFDM symbols. A given PDCCH can be composed of 1, 2, 4, 8, and 16 CCEs, and its specific value can be determined by the DCI (Downlink Control Information) payload size and the required coding rate. The number of CCEs constituting the PDCCH is called aggregation level (AL, aggregation level).

Optionally, in the embodiment of the present application, the method further includes:

The network device determines a group of CCEs corresponding to the resource of the candidate control channel in a pre-configuration manner.

Optionally, in this embodiment of the application, each CCE in the group of CCEs is divided into one or more REG bundles, and the index of the REG bundle corresponding to the CCE is uniquely determined according to each CCE index.

Optionally, in this embodiment of the application, the indexes of the REG bundles corresponding to each CCE are different from each other, and the indexes of the REG bundles corresponding to different CCEs are different from each other.

In the embodiment of the present application, the REG is a physical resource unit that occupies one OFDM symbol in the time domain and one resource block (including 12 consecutive subcarriers in the frequency domain) in the frequency domain. In one REG, 3 REs (Resource Elements) are used to map PDCCH demodulation reference signals, and 9 REs are used to map DCI REs. The REG bundle includes multiple consecutive REGs in the time domain and/or frequency domain. The number of REGs constituting a REG bundle may be 1, 2, 3, or 6. And the PDCCH mapped in one REG bundle adopts the same precoding (precoder), that is, the UE can use the demodulation reference signal in the REG bundle to perform joint channel estimation in the time domain and/or frequency domain. Using the REG bundle enables the UE to use the demodulation reference signals of all REGs in the REG bundle to perform channel estimation, thereby improving the accuracy of channel estimation. The number of REGs included in the REG bundle in the time domain and the frequency domain is related to the configuration of the CORESET (CONTROL RESOURCE SET, control resource set) time domain symbol number and the REG bundle size. Examples of specific values are as follows.

Optionally, in this embodiment of the present application, the frequency domain granularity of the control information during precoding is one REG bundle.

In an example, the number of REGs constituting the REG bundle may be 2, 3, and 6. The coding method can be the size of this REG bundle, or the continuous RB in CORESET, which is broadband precoding.

Optionally, in the embodiment of the present application, the frequency domain granularity of the control information during precoding is all continuous resource blocks RB in the physical resource to which the control channel belongs.

Optionally, in the embodiment of the present application, the network device configures the CCE to REG bundle mapping mode to the terminal device through pre-configuration and/or high-level signaling.

In this implementation manner, the network device configures the CCE to REG bundle mapping mode to the terminal device through pre-configuration and/or high-level signaling, which can ensure that the configuration of the network device and the terminal device are consistent.

Optionally, in this embodiment of the present application, any one of the at least two resources occupied by the control information is a first resource; the first resource is a set of second resources corresponding to the first TCI state; the first resource The TCI state is any one of the at least two TCI states configured by the network device for the control information.

For example, the network device configures N TCI states for the PDCCH. N is greater than or equal to 2. Take two TCI states: TCI state 0 and TCI state 1 as an example. Different TCI states may come from different TRPs.

Optionally, in this embodiment of the present application, according to the difference of the second resource, the method for determining the set of the second resource corresponding to the first TCI state may be different.

Assume that the number of TCI states is two: TCI state0 and TCI state1. The two TCI states are mapped to each group in cycles, and the set of CCEs corresponding to each TCI state can be obtained. Taking the above five groups as an example, after mapping, each TCI state corresponds to the set of CCEs as follows: {CCE 9, CCE8} corresponds to TCI state0; {CCE7, CCE 6} corresponds to TCI state1; {CCE5, CCE4} corresponds to TCI state0 ; {CCE 3, CCE2} corresponds to TCI state1; {CCE1, CCE 0} corresponds to TCI state0.

By mapping these three TCI state cycles to each grouping, a set of CCEs corresponding to each TCI state can be obtained. Taking the above four groups as an example, after mapping, each TCI state corresponds to the set of CCEs as follows: {CCE 9, CCE8, CCE7} corresponds to TCI state0; {CCE 6, CCE5, CCE4} corresponds to TCI state1; {CCE3, CCE2, CCE1} correspond to TCI state2; {CCE 0} correspond to TCI state0.

For example, the k CCEs in the candidate PDCCH are sorted into CCE 0, CCE 1, CCE 2,..., CCE k-2, CCE k-1 according to the CCE index from small to large.

Assuming that k is 10 and s is 2, the 5 groups after sorting are {CCE0, CCE1}; {CCE2, CCE3}; {CCE4, CCE5}; {CCE6, CCE7}; {CCE 8, CCE9}.
