Fig. 2 is a schematic flow chart diagram of a transmission method 200 according to an embodiment of the present application. The method may alternatively be applied to the system shown in fig. 1, but is not limited thereto. The method includes at least part of the following.

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 at least two configured resources.

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

Optionally, in this 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 embodiment of the present application, a PDCCH is used for illustration, and the PUCCH may refer to an example of the PDCCH, which is not described herein again.

Optionally, in this embodiment of the present application, the at least two resources respectively transmit the same control information that is independent and can be detected. For example, two resources each transmit the same PDCCH, which are independent and detectable.

Optionally, in this embodiment of the present application, the at least two resources respectively transmit different portions of the same control information. For example, two resources transmit different parts of the same PDCCH, respectively, which make up the complete PDCCH.

Taking control information as PDCCH as an example, when retransmission (repetition) transmission of PDCCH is performed through a plurality of TRPs, each TRP has one TCI state, and TCI states of different TRPs are different. In this case, the transmission mode of the control information may be configured as the transmission mode of FDM, and the independent TCI states (TCI states) of at least two resource configurations occupied by PDCCH may be configured, so as to clarify the mode in which a plurality of TRPs are transmitted by FDM. FDM is a multiplexing technique that modulates multiple baseband signals onto different frequency carriers and superimposes them to form a composite signal.

In the embodiment of the present application, the network device configures the independent TCIs configured for at least two resource occupied by the control information, so that a transmission mode can be determined under the condition that the control channel is transmitted through a plurality of TRPs, so that the terminal device can correctly demodulate the control channel. For example, in the case of retransmission transmission of PDCCH by a plurality of TRPs, the manner of retransmission is explicitly repeated so that the terminal device can correctly demodulate PDCCH candidates.

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

The network device configures a CORESET (Control Resource Set) and a Search Space (Search Space) for transmission of the PDCCH. The control resource set includes a plurality of physical resource blocks in a Frequency domain, may include 1 to 3 OFDM (Orthogonal Frequency Division Multiplexing) symbols in a time domain, and may be located at any position within a slot. The time domain resources occupied by the CORESET are configured by high-level parameters in a semi-static mode. The search space is a set of pdcch (pdcch candidate) candidates at one or more aggregation levels. The aggregation level of the PDCCH actually sent by the base station is variable with time, and since no related signaling is notified to the UE (User Equipment), the UE needs to perform blind detection on the PDCCH at different aggregation levels. The PDCCH to be blind detected is referred to as a PDCCH candidate. And the UE decodes all the candidate PDCCHs in the search space, if CRC (Cyclic Redundancy Check) Check is passed, the content of the decoded PDCCHs is considered to be effective to the UE, and subsequent operation is carried out by utilizing the information obtained by decoding.

In NR (New Radio ), in each downlink BWP (Bandwidth Part, Part of Bandwidth) of each serving cell, a network device may configure at most 10 search space sets for a user, where the search space sets are configured with time domain configuration information to indicate a time domain position where the user detects a PDCCH. And the network device configures the CORESET ID associated with the set for each search space set, and the user can obtain the physical resources of the search space set on the frequency domain through the CORESET ID. Each set of search spaces has a uniquely associated CORESET ID. Different sets of search spaces may be associated with the same CORESET ID. The UE determines the time-frequency domain position of PDCCH candidate according to the time domain given by the search space set and the frequency domain of the associated CORESET ID and other parameters in the search space set.

When configuring the core set, the network device configures one or a group of TCI states for each core set, where the TCI states are used to indicate channel filtering parameters corresponding to a user when performing demodulation detection on a PDCCH candidate associated with the core set. When the network device configures a set of TCI states for a certain CORESET, the network device activates a unique TCI state for the CORESET through MAC CE signaling to indicate channel filtering parameters of the UE when demodulating PDCCH.

In addition, the network device configures a highher layer index (higher layer identifier) for each CORESET to indicate whether the CORESET is the same TRP. The values range between 0 and 1. For CORESET configured with the same higher layer index, the user thinks this is data from the same TRP.

Optionally, in this embodiment of the present application, the resource of the candidate Control Channel includes a set of CCEs (Control Channel elements) configured by the network device, and each CCE in the set of CCEs has a unique index in the resource of the candidate Control Channel. For example, each CCE in a set of CCEs has a unique index in the resource of the PDCCH candidate: CCE0, CCE1, CCE2, … …, etc.

In the embodiment of the present application, a CCE is a basic unit constituting a PDCCH and occupies 6 REGs (Resource Element Group). The 6 REGs may be 6 REGs on 1 OFDM symbol, or 3 REGs on 2 OFDM symbols, or 2 REGs on 3 OFDM symbols. A given PDCCH may be formed by 1, 2, 4, 8, and 16 CCEs, and a specific value thereof may be determined by a DCI (Downlink control information) payload size and a required coding rate. The number of CCEs constituting a PDCCH is called Aggregation Level (AL).

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

and the network equipment determines a group of CCEs corresponding to the resources of the candidate control channel in a pre-configured mode.

Optionally, in this embodiment of the present application, each CCE in the set of CCEs is divided into one or more REG chunks, and an index of the REG chunk corresponding to the CCE is uniquely determined according to each CCE index.

Optionally, in this embodiment of the present application, indexes of REG bundles corresponding to each CCE are different from each other, and indexes of 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 occupying one OFDM symbol in the time domain and one resource block (including 12 subcarriers consecutive in the frequency domain) in the frequency domain. In one REG, 3 REs (Resource elements) are used for mapping PDCCH demodulation reference signals, and 9 REs are used for mapping REs of DCI. The REG bundle includes a plurality of REGs that are contiguous in time and/or frequency domains. The number of REGs constituting the REG bundle may be 1, 2, 3, or 6. And the PDCCH mapped within one REG bundle employs the same precoding (precoder), i.e., the UE can perform time-domain and/or frequency-domain joint channel estimation using the demodulation reference signal within the REG bundle. The REG bundle is utilized to enable the UE to utilize the demodulation reference signals of all REGs in the REG bundle to carry out channel estimation, thereby improving the channel estimation precision. The number of REGs included in the REG bundle in time and frequency domains is related to the number of core RESOURCE SET (CONTROL RESOURCE SET) time domain symbols and the configuration of REG bundle size. Specific values are shown in the following table.

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

In one example, the number of REGs constituting the REG bundle may be 2, 3, and 6. The coding method may be the size of this REG bundle, or may be continuous RBs in the core set, that is, wideband precoding.

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

Optionally, in this embodiment of the present application, the network device configures, to the terminal device, a mapping manner from the CCE to the REG bundle through pre-configuration and/or high-layer signaling.

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

Optionally, in this embodiment of the present application, any one of 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 TCI state is any one of at least two TCI states configured for control information by the network device.

For example, the network device configures N TCI states for PDCCH. N is greater than or equal to 2. With 2 TCI states: TCI state0 and TCI state1 are examples. Different TCI states may result from different TRPs.

Optionally, in this embodiment of the application, according to a difference of the second resource, a determination manner of the set of second resources corresponding to the first TCI state may be different.

The first method is as follows: the second resource is in CCE unit, and the determination method of the set of second resources corresponding to the first TCI state includes:

sequencing CCEs occupied by resources of the candidate control channels;

grouping according to integral multiple of CCE size as a unit;

and circularly mapping to each group according to the configured number of the TCI states to obtain a set of CCEs corresponding to the first TCI state.

The candidate control channels, for example, k CCEs are occupied by resources of the candidate PDCCH, and the candidate PDCCHs are grouped by integer multiples of the CCE size s. Assume that k is 10 and s is 2, grouping is 5. Assume that k is 10, s is 3, and the number of packets is 4. If the number of TCI states is N. And circularly mapping the number N of the configured TCI states to each group to obtain a set of CCEs corresponding to each TCI state.

Optionally, in this embodiment of the present application, the manner of sorting CCEs occupied by resources of the candidate control channel includes: and sequencing according to the sequence of the CCE indexes in the candidate control channels from large to small.

For example, the k CCEs in the candidate PDCCH are ordered into CCE k-1, CCE k-2, … … CCE2, CCE1 and CCE0 according to the descending order of CCE indexes.

Let k be 10, s be 2, and the 5 sorted packets be { CCE9, CCE8 }; { CCE7, CCE6 }; { CCE5, CCE4 }; { CCE3, CCE2 }; { CCE1, CCE0 }.

Assuming that k is 10 and s is 3, the 4 sorted groups are { CCE9, CCE8, CCE7 }; { CCE6, CCE5, CCE4 }; { CCE3, CCE2, CCE1 }; { CCE0 }.

Assume that the number of TCI states is 2: TCI state0 and TCI state 1. The two TCI state numbers 2 are circularly mapped to each packet, and a set of CCEs corresponding to each TCI state can be obtained. Taking the above 5 packets as an example, after mapping, the set of CCEs corresponding to each TCI state is as follows: { CCE9, CCE8} corresponds to TCI state 0; { CCE7, CCE 6} corresponds to TCI state 1; { CCE5, CCE4} corresponds to TCI state 0; { CCE3, CCE2} corresponds to TCI state 1; { CCE1, CCE 0} corresponds to TCI state 0.

Assume that the number of TCI states is 3: TCI state0, TCI state1, and TCI state 2. The 3 TCI states are cyclically mapped to each packet, and a set of CCEs corresponding to each TCI state can be obtained. Taking the above 4 packets as an example, after mapping, the set of CCEs corresponding to each TCI state is as follows: { CCE9, CCE8, CCE7} corresponds to TCI state 0; { CCE6, CCE5, CCE4} corresponds to TCI state 1; { CCE3, CCE2, CCE1} corresponds to TCI state 2; { CCE 0} corresponds to TCI state 0.

Optionally, in this embodiment of the present application, the manner of sorting CCEs occupied by resources of a candidate control channel includes: and sequencing according to the sequence of the CCE indexes in the candidate control channels from small to large.

For example, the k CCEs in the candidate PDCCH are ordered into CCE0, CCE1, CCE2, … …, CCE k-2 and CCE k-1 according to the sequence of the CCE indexes from small to large.

Assuming that k is 10 and s is 2, the 5 sorted packets are { CCE0, CCE1 }; { CCE2, CCE3 }; { CCE4, CCE5 }; { CCE6, CCE7 }; { CCE8, CCE9 }.

Assuming that k is 10 and s is 3, the 4 sorted packets are { CCE0, CCE1 and CCE2 }; { CCE3, CCE4, CCE5 }; { CCE6, CCE7, CCE8 }; { CCE9 }.

Assume that the number of TCI states is 2: TCI state0 and TCI state 1. The two TCI states are mapped to each packet cyclically, and a set of CCEs corresponding to each TCI state can be obtained. Taking the above 5 packets as an example, after mapping, the set of CCEs corresponding to each TCI state is as follows: { CCE0, CCE1} corresponds to TCI state 0; { CCE2, CCE3} corresponds to TCI state 1; { CCE4, CCE5} corresponds to TCI state 0; { CCE6, CCE7} corresponds to TCI state 1; { CCE8, CCE9} corresponds to TCI state 0.

Assume that the number of TCI states is 3: TCI state0, TCI state1, and TCI state 2. The 3 TCI states are cyclically mapped to each packet, and a set of CCEs corresponding to each TCI state can be obtained. Taking the above 4 packets as an example, after mapping, the set of CCEs corresponding to each TCI state is as follows: { CCE0, CCE1, CCE2} corresponds to TCI state 0; { CCE3, CCE4, CCE5} corresponds to TCI state 1; { CCE6, CCE7, CCE8} corresponds to TCI state 2; { CCE9} corresponds to TCI state 0.

The second method comprises the following steps: the second resource uses REG bundle as a unit, and the determining mode of the set of second resources corresponding to the first TCI state further includes:

sequencing REG bundles corresponding to all CCE resources of the candidate control channel;

grouping according to the integral multiple of the size of the REG bundle as a unit;

and circularly mapping to each group according to the configured number of the TCI states to obtain a set of REG bundle corresponding to the first TCI state.

For example, the resources of the candidate PDCCH occupy p REG bundles, and the REG bundles are grouped by integer multiple of size t. Assume that p is 16, t is 4, and the packet is 4. Assume that k is 16, t is 6, and the packet is 3. If the number of TCI states is N. And circularly mapping to each group according to the configured TCI state number N to obtain a REG bundle set corresponding to each TCI state.

Optionally, in this embodiment of the present application, the manner of sorting REG bundles corresponding to all CCE resources of the candidate control channel includes: sorting according to the descending order of all REG bundle indexes (indexes) in the candidate control channel.

For example, the p CCEs in the PDCCH candidates are ordered as REG bundle p-1, REG bundle p-2, … … REG bundle2, REG bundle1 and REG bundle 0 according to the sequence of CCE indexes from large to small.

Assuming that p is 16 and t is 4, the 4 sorted groups are { REG bundle 15, REG bundle14, REG bundle13, REG bundle12 }; { REG bundle11, REG bundle10, REG bundle9, REG bundle8 }; { REG bundle7, REG bundle6, REG bundle5, REG bundle4 }; { REG bundle3, REG bundle2, REG bundle1, REG bundle 0 }.

Assuming that k is 16 and t is 6, the sorted 3 groups are { REG bundle 15, REG bundle14, REG bundle13, REG bundle12, REG bundle11, REG bundle10 }; { REG bundle9, REG bundle8, REG bundle7, REG bundle6, REG bundle5, REG bundle4 }; { REG bundle3, REG bundle2, REG bundle1, REG bundle 0 }.

Assume that the number of TCI states is 2: TCI state0 and TCI state 1. The two TCI state numbers 2 are circularly mapped to each packet, and a set of CCEs corresponding to each TCI state can be obtained. Taking the above 4 packets as an example, after mapping, the set of CCEs corresponding to each TCI state is as follows: { REG bundle 15, REG bundle14, REG bundle13, REG bundle12} corresponds to TCI state 0; { REG bundle11, REG bundle10, REG bundle9, REG bundle8} correspond to TCI state 1; { REG bundle7, REG bundle6, REG bundle5, REG bundle4} corresponds to TCI state 0; { REG bundle3, REG bundle2, REG bundle1, REG bundle 0} corresponds to TCI state 1.

Assume that the number of TCI states is 3: TCI state0, TCI state1, and TCI state 2. The 3 TCI states are cyclically mapped to each packet, and a set of CCEs corresponding to each TCI state can be obtained. Taking the above 3 packets as an example, after mapping, the set of CCEs corresponding to each TCI state is as follows: { REG bundle 15, REG bundle14, REG bundle13, REG bundle12, REG bundle11, REG bundle10} correspond to TCI state 0; { REG bundle9, REG bundle8, REG bundle7, REG bundle6, REG bundle5, REG bundle4} correspond to TCI state 1; { REG bundle3, REG bundle2, REG bundle1, REG bundle 0} corresponds to TCI state 2.

Optionally, in this embodiment of the present application, the manner of sorting REG bundles corresponding to all CCE resources of the candidate control channel includes: and sorting according to the sequence of all REG bundle indexes in the candidate control channel from small to large.

For example, the p CCEs in the PDCCH candidates are sorted into REG bundle 0, REG bundle1, REG bundle2, … …, REG bundle p-2 and REG bundle p-1 according to the sequence of the indexes of the CCE resources corresponding to the REG bundles from small to large.

Assuming that p is 16 and t is 4, the 4 sorted groups are { REG bundle 0, REG bundle1, REG bundle2, REG bundle3 }; { REG bundle4, REG bundle5, REG bundle6, REG bundle7 }; { REG bundle8, REG bundle9, REG bundle10, REG bundle11 }; { REG bundle12, REG bundle13, REG bundle14, REG bundle 15 }.

Assuming that k is 16 and t is 6, the sorted 3 packets are { REG bundle 0, REG bundle1, REG bundle2, REG bundle3, REG bundle4, REG bundle5 }; { REG bundle6, REG bundle7, REG bundle8, REG bundle9, REG bundle10, REG bundle11 }; { REG bundle12, REG bundle13, REG bundle14, REG bundle 15 }.

Assume that the number of TCI states is 2: TCI state0 and TCI state 1. The two TCI state numbers 2 are circularly mapped to each packet, and a set of CCEs corresponding to each TCI state can be obtained. Taking the above 4 packets as an example, after mapping, the set of CCEs corresponding to each TCI state is as follows: { REG bundle 0, REG bundle1, REG bundle2, REG bundle3} correspond to TCI state 0; { REG bundle4, REG bundle5, REG bundle6, REG bundle7} correspond to TCI state 1; { REG bundle8, REG bundle9, REG bundle10, REG bundle11} corresponds to TCI state 0; { REG bundle12, REG bundle13, REG bundle14, REG bundle 15} corresponds to TCI state 1.

Assume that the number of TCI states is 3: TCI state0, TCI state1, and TCI state 2.
