Abstract
The invention discloses a transmission method, a device, network equipment, a terminal and a system of channel resources. Wherein, the method comprises the following steps: the network equipment sends candidate control channels in at least one search space to the terminal equipment; the resources occupied by the candidate control channels are determined according to the transmission configuration indication states corresponding to the candidate control channels and the control resource sets corresponding to the transmission configuration indication states corresponding to the candidate control channels. The invention solves the technical problem that the PDCCH cannot be correctly received subsequently when the UE detects the PDCCH on the frequency domain resource because the frequency domain resource of the PDCCH is configured according to the number of the candidate channels in the search space in the related technology.
Description
The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, a network device, a terminal, and a system for transmitting channel resources.
A network device (e.g., a base station) configures a Control resource set (CORESET) and a Search Space (Search Space) to enable transmission of a Physical Downlink Control Channel (PDCCH). The control resource set includes a plurality of physical resource blocks in a Frequency domain, includes 1 to 3 Orthogonal Frequency Division Multiplexing (OFDM) symbols in a time domain, and can be located at any position in a time 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 candidates (PDCCH 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 relevant signaling is given to a User Equipment (User Equipment, UE for short), the UE needs to perform blind detection on the PDCCH at different aggregation levels, where the PDCCH to be subjected to blind detection is referred to as a candidate PDCCH. The UE decodes all PDCCH candidates in the search space, and if Cyclic Redundancy Check (CRC) passes, the decoded PDCCH content is considered to be valid for the UE, and the information obtained by decoding is used for subsequent operations.
In New Radio (NR), in each downlink partial Bandwidth (BWP) of each serving cell, a network device may configure 10 search space sets at most for a user, where the search space sets are configured with time domain configuration information to indicate a time domain position of a PDCCH detected by the user. Meanwhile, the network side configures a control resource set identifier (CORESET ID) associated with the set for each search space set, and a 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 associated frequency domain of the CORESET ID and other parameters in the search space set.
When configuring the core set, the network device configures one or a set of Transmission configuration indicator states (TCI states for short) for each core set, where the TCI state is used to indicate a channel filter coefficient corresponding to a user when performing demodulation detection on a PDCCH candidate of the Search Space associated with the core set. When the network configures a group of TCI states for a certain CORESET, the network device activates a unique TCI state for the CORESET through a MAC Control Element (MAC CE) signaling to indicate a channel filter coefficient when the UE demodulates the PDCCH.
In the related art, if the Search Space is associated with a plurality of core sets, and each core set is configured with an independent PDCCH candidate number, when calculating the frequency domain resource of the PDCCH, the frequency domain resource of the PDCCH is calculated according to the number of candidate channels in the Search Space, which may cause that the UE may incorrectly understand the frequency domain resource when performing reception detection on the PDCCH, thereby causing a problem that the PDCCH cannot be correctly received subsequently.

Optionally, in the transmission method of channel resources provided in the embodiment of the present application, the association relationship between at least one search space and at least two transmission configuration indication states includes:
the method I comprises the following steps: at least two candidate control channels in the at least one search space are respectively associated with different transmission configuration indication states;

It should be noted that, in conjunction with fig. 2a to 2d, the relationship between ss, coreset, tci state and PDCCH candidate may be: each TCI state is respectively activated corresponding to the CORESET, and/or each TCI state is activated based on the same CORESET;
for example: TCI state 1 is activated by the base station CORESET1, TCI state 2 is activated by the base station CORESET 2, \ 8230; \ 8230; TCI state N is activated by the base station CORESET N; and/or TCI state 1, TCI state 2, \8230 \8230andTCI state N are activated by the base station for CORESET simultaneously.
In the case of "and", i.e. at least two transmission configuration indication states are activated by the network device for different sets of control resources, respectively; and at least two transmission configuration indication states are activated by the network device for one control resource set at the same time, and may correspond to the implementation scenario of the above-mentioned manner three, and are activated by the network device for different control resource sets according to the at least two transmission configuration indication states, respectively, for different SSs; and, the at least two transmission configuration indication states are configuration TCI states that the network device activates simultaneously for one set of control resources.
Further, optionally, different control resource sets have different control resource set pool indices.
In an implementable manner, combining the scenarios in the above manners one to three, in the case where there are multiple CORESETs, each CORESET has a respective corresponding CORESET pool index.
Optionally, the network device configures a transmission configuration indication state associated with the control resource set by configuring the associated control resource set for the search space.
As shown in fig. 2a to 2d, by configuring a corresponding CORESET for the SS, and associating a corresponding TCI state by the CORESET; for example: by combining the foregoing manners one to three, taking an SS as an example, when configuring an SS, the SS may configure one CORESET or multiple CORESETs, and in the case of configuring one CORESET, configure multiple TCI states associated with the CORESET; in the case of configuring multiple CORESET, the TCI state associated with each CORESET is configured, i.e., each CORESET corresponds to one TCI state.
Based on the above configuration, the process of the network device sending the candidate control channels in at least one search space to the terminal device, that is, the process of the base station sending the candidate PDCCHs to the smartphone through at least two TCI states, may include the following ways:
the method I comprises the following steps: when the network equipment sends the downlink control information through the candidate control channels, the downlink control information is sent through one of the candidate control channels and at least two transmission configuration indication states associated with the candidate control channels;
when the base station transmits Downlink control information, for example, DCI (Downlink control signaling), when one PDCCH candidate is associated with at least two TCI states, the base station may transmit the Downlink control information via one PDCCH candidate of the plurality of PDCCH candidates and the at least two TCI states associated with the PDCCH candidate.
The second method comprises the following steps: when the network equipment sends the downlink control information through the candidate control channels, sending the downlink control information through transmission configuration indication states respectively associated with at least two candidate control channels and at least two candidate control channels;
when the base station transmits Downlink control information, for example, DCI (Downlink control signaling), under the condition that each PDCCH candidate is associated with a corresponding TCI state, the Downlink control information may be transmitted through at least two PDCCH candidates and the TCI states associated with the at least two PDCCH candidates.
The third method comprises the following steps: when the network equipment sends the downlink control information through the candidate control channels, the downlink control information is sent through one of the candidate control channels and at least two transmission configuration indication states associated with the candidate control channels; and transmitting the downlink control information through the transmission configuration indication states respectively associated with the at least two candidate control channels and the at least two candidate control channels.
In combination with the first and second manners, when there are multiple candidate PDCCHs, some candidate PDCCHs are associated with at least two TCI states, and some candidate PDCCHs are in one-to-one correspondence with TCI states, the base station selects different types of candidate PDCCHs from the multiple candidate PDCCHs, and performs transmission of downlink control information through the TCI states associated with the types of candidate PDCCHs, which may be specifically implemented by simultaneously transmitting the downlink control information through the first and second manners.
Further, optionally, the step of determining the resource occupied by the candidate control channel includes: the network equipment determines the aggregation level of the candidate control channels; the network equipment determines the number of candidate control channels related to the same transmission configuration indication state in the aggregation level; the network equipment determines physical resources of a control resource set corresponding to the transmission configuration indication state; and the network equipment determines the resources occupied by the candidate control channels during transmission based on the number of the candidate control channels and the physical resources of the control resource set.
In an implementation manner, the network device takes an SS as an example, and the network device takes a base station as an example to illustrate:
a base station configures a Search Space, wherein the Search Space is associated with 2 CORESETs;
the base station activates only one TCI state at any one time for each CORESET.
The base station configures 8 PDCCH candidates for aggregation level 8 of Search Space, where the first 4 PDCCH candidates are sent only by the TCI state indicated by CORESET0, and the last 4 PDCCH candidates are sent only by the TCI state indicated by CORESET 1. In this embodiment, the aggregation level 8 may be any aggregation level, or only a part of the aggregation levels may be configured, so as to implement the transmission method of the channel resource provided in this embodiment, which is not specifically limited.
The network device determines the resources occupied by the transmission of the candidate control channels based on the number of the candidate control channels and the physical resources of the control resource set, and the resources occupied by the transmission of the candidate control channels comprise:
for only the CORESET0, the base station calculates, based on the number of PDCCH candidates corresponding to the TCI state indicated by the CORESET0 and the number of CCEs of the CORESET0 (i.e., the physical resource of the Control resource set in the embodiment of the present application) in the Search Space, CCE (Control Channel Element) resources (i.e., resources occupied by the PDCCH of the number of PDCCH candidates during transmission). Namely that
When CCE resources are calculated, m s,nci Only the candidate PDCCHs for the TCI state indicated by CORESET0 in the search space (in this embodiment, candidate PDCCHs 0-3 correspond to CORESET0, and candidate PDCCHs 4-7 correspond to CORESET1, where m is the CCE resource of the candidate PDCCHs in CORESET0 when calculated s,nci 0-3 correspond to PDCCH candidates 0-3 in order, and m is the CCE resource of PDCCH candidate in CORESET1 s,nci 0-3 in turn correspond to PDCCH candidates 4-7). N is a radical of CCE,p The number of CCEs of CORESET corresponding to the candidate PDCCH.For all configured cells n in the search space s CI Only the maximum value of the number of PDCCHs candidate of aggregation level L configured for the terminal by CORESET0 is associated.
The terminal device (e.g., a smart phone) determines a CCE resource corresponding to each candidate PDCCH based on the number of candidate PDCCHs associated with each CORESET of the network device (e.g., a base station), and receives the detection PDCCH on the corresponding CCE resource.
To sum up, the transmission method of channel resources provided in the embodiment of the present application includes the following steps when sending downlink control information:
in a first mode, a network device sends downlink control information through at least two transmission configuration indication states associated with one candidate control channel and the candidate control channel, including: the network equipment respectively sends the downlink control information once through each transmission configuration indication state associated with one candidate control channel; or, the network device sends each transmission configuration indication state associated with a candidate control channel through which each part of the downlink control information passes.
Wherein, the downlink control information may be transmitted once through a plurality of TCI states associated with one candidate PDCCH, that is, one piece of downlink control information is repeatedly transmitted through each TCI state associated with one candidate PDCCH;
or the like, or a combination thereof,
transmitting each part of the downlink control information through each TCI state associated with the candidate PDCCH, namely splitting a piece of downlink control information, and sending each part of the split downlink control information by each TCI state associated with the determined candidate PDCCH; for example, each TCI state corresponds to a part of the downlink control information. As shown in fig. 2e, fig. 2e is a schematic diagram illustrating a position correspondence between each TCI state and split downlink control information in a transmission method of channel resources according to an embodiment of the present invention.
In a second mode, the network device sends the downlink control information through the transmission configuration indication states respectively associated with the at least two candidate control channels and the at least two candidate control channels, including: the network equipment sends the same downlink control information through at least two candidate control channels; or, the network device transmits the content of different parts of the same downlink control information through at least two candidate control channels; wherein, the transmission configuration indication states respectively associated with the at least two candidate control channels are different.
Different from the first mode, in the second mode, the network device transmits the downlink control information through at least two candidate PDCCHs in the SS, and in the transmission process, the at least two candidate PDCCHs may be enabled to transmit the same downlink control information; it is also possible to let two candidate PDCCHs transmit the content of different parts of the same downlink control information.
For example: when the downlink control information is transmitted, the same downlink control information can be respectively transmitted through the candidate PDCCH1 and the candidate PDCCH2, that is, the repeated information is transmitted by using two channels; or the like, or a combination thereof,
the downlink control information includes part1 and part2, and when transmitting, part1 part is transmitted through PDCCH candidate 1 and part2 part is transmitted through PDCCH candidate 2.
It should be noted that the transmission configuration indication states associated with the two candidate control channels are different, that is, PDCCH candidate 0 corresponds to TCI state 0, and PDCCH candidate 1 corresponds to TCI state 1.
In a third mode, the network equipment sends the downlink control information through one candidate control channel and at least two transmission configuration indication states associated with the candidate control channel; and transmitting the downlink control information through transmission configuration indication states respectively associated with the at least two candidate control channels and the at least two candidate control channels, including: the network equipment respectively sends downlink control information through each transmission configuration indication state associated with a candidate control channel; or, the network device sends each transmission configuration indication state associated with a candidate control channel through which each part of the downlink control information passes; the network equipment sends the same downlink control information through at least two candidate control channels; or, the network device transmits the content of different parts of the same downlink control information through at least two candidate control channels; wherein, the transmission configuration indication states respectively associated with the at least two candidate control channels are different.
The third mode is a mode for realizing the combination of the first mode and the second mode when the downlink control information is sent.
Optionally, the method for transmitting channel resources provided in the embodiment of the present application further includes: the network equipment indicates the incidence relation among the candidate control channels in the search space; when the network equipment determines that the downlink control information is transmitted through one candidate control channel in the search space, the network equipment determines that the downlink control information is repeatedly transmitted through the corresponding candidate control channel in the search space according to the incidence relation between the candidate control channels; or determining that the contents of each part of the downlink control information are respectively transmitted through corresponding candidate control channels in the search space.
Based on the second mode, the network equipment transmits downlink control information through the association relation between the candidate PDCCHs in the SS;
for example: there is some correspondence between 8 candidate PDCCHs transmitted through TCI state 0 and 5 candidate PDCCHs transmitted through TCI state 1 with an aggregation level of 8 indicated by pre-configuration or higher layer signaling. That is, when the network device selects to transmit downlink control information through the ith candidate PDCCH of the first 3 candidate PDCCHs, the network device may transmit the same downlink control information through the same kth candidate PDCCH of the last 5 candidate PDCCHs. Or,
part1 of the downlink control information is transmitted through the i candidate PDCCHs, and part2 of the downlink control information is transmitted through the kth candidate PDCCH.
In summary, the transmission method of channel resources provided in the embodiments of the present application includes the following examples in practical applications:
example 1:
the network device configures a Search Space associated with 2 CORESET.
The network device has only one TCI state activated at any one time for each CORESET.
The network device configures 8 candidate PDCCHs for aggregation level 8 of Search Space, where the first 4 candidate PDCCHs are transmitted only by the TCI state indicated by CORESET0, and the last 4 candidate PDCCHs are transmitted only by the TCI state indicated by CORESET 1. The aggregation level may be any aggregation level, or only a part of the aggregation levels may be configured.
The network device sends the Search Space and one candidate PDCCH in the candidate PDCCHs corresponding to the TCI state indicated by the associated CORESET0 to the terminal device and indicates related downlink control information, wherein the indicated downlink control information can be used for scheduling a channel;
the network device sends the Search Space and one candidate PDCCH of candidate PDCCHs corresponding to the TCI state indicated by the associated core set1 to the terminal device and indicates related downlink control information, where the indicated downlink control information may be used to schedule a channel.
The PDCCHs respectively transmitted by the network device through TCI state 0 of CORESET0 and TCI state 1 of CORESET1 may be the same channel used for scheduling or different channels.
When the same channel is scheduled, the network device may indicate, through pre-configuration or high-layer signaling, that there is some correspondence between the first 4 candidate PDCCHs with an aggregation level of 8 and the last 4 candidate PDCCHs. That is, when the network device selects to transmit downlink control information through the ith candidate PDCCH of the first 4 candidate PDCCHs, the network device may transmit the same downlink control information through the same kth candidate PDCCH of the last 4 candidate PDCCHs. The two downlink control information schedules the same channel.
Based on the TCI state associated with CORESET0 as an example, the network device calculates, based on the number of PDCCH candidates associated with only the TCI state indicated by CORESET0 in the Search Space and the number of CCE of CORESET0, a CCE (Control Channel Element) resource occupied by a Channel of the number of PDCCH candidates. The calculation process is as follows:
when CCE resources are calculated, m s,nci PDCCH candidates only for the TCI state indicated for CORESET0 in the search space (in this example, PDCCH candidates 0-3 correspond to CORESET0, PDCCH candidates 4-7 correspond to CORESET1, where m is the CCE resource of PDCCH candidate in CORESET0 is calculated s,nci 0-3 correspond to PDCCH candidates 0-3 in order, and m is the CCE resource of PDCCH candidate in CORESET1 s,nci 0-3 in turn correspond to PDCCH candidates 4-7). N is a radical of hydrogen CCE,p The number of CCEs of CORESET corresponding to the PDCCH candidate.For all configured cells n in the search space s CI Only the maximum value of the candidate PDCCHs of aggregation level L configured for the terminal device by the CORESET0 is associated.
The terminal equipment determines CCE resources corresponding to each candidate PDCCH based on the number of the candidate PDCCHs associated with each CORESET indicated by the network equipment, and receives the detection PDCCH on the corresponding CCE resources.
Example 2:
the network device configures a Search Space associated with 2 CORESET.
The network device activates only one TCI state at any one time for each CORESET.
The network device configures 8 PDCCH candidates for aggregation level 8 of Search Space, where the first 3 PDCCH candidates are sent only by the TCI state indicated by CORESET0, and the last 5 PDCCH candidates are sent only by the TCI state indicated by CORESET 1.
It should be noted that this example differs from example 1 in that: the number of candidate PDCCHs related to CORESET0 is different from the number of candidate PDCCHs related to CORESET 1;
that is, in example 1, the first 4 PDCCH candidates among the number of PDCCH candidates according to aggregation level 8 are allocated to the TCI state indicated by CORESET0 for transmission; the last 4 candidate PDCCHs are allocated to TCI state transmission indicated by CORESET 1;
the TCI state transmission indicated by CORESET0 is allocated according to the first 3 PDCCH candidates according to aggregation level 8 in this example; the last 5 PDCCH candidates are allocated to the TCI state transmission indicated by CORESET1 for setting.
The network device sends the Search Space and one candidate PDCCH of candidate PDCCHs corresponding to the TCI state indicated by the associated CORESET0 to the terminal device and indicates related downlink control information, wherein the indicated downlink control information may be used to schedule a channel;
the network device sends the Search Space and one candidate PDCCH of candidate PDCCHs corresponding to the TCI state indicated by the associated core set1 to the terminal device and indicates related downlink control information, where the indicated downlink control information may be used to schedule a channel.
The PDCCHs respectively transmitted by the network device through TCI state 0 of CORESET0 and TCI state 1 of CORESET1 may be the same channel used for scheduling or different channels.
When the same channel is scheduled, the network device may indicate, through pre-configuration or higher layer signaling, that there is some correspondence between the first 3 candidate PDCCHs and the last 5 candidate PDCCHs with an aggregation level of 8. That is, when the network device selects to transmit downlink control information through the ith candidate PDCCH of the first 3 candidate PDCCHs, the network device may transmit the same downlink control information through the same kth candidate PDCCH of the last 5 candidate PDCCHs. The two downlink control information schedules the same channel.
Based on the TCI state associated with CORESET0 as an example, the network device calculates, based on the number of PDCCH candidates associated with only the TCI state indicated by CORESET0 in the Search Space and the number of CCE of CORESET0, a CCE (Control Channel Element) resource occupied by a Channel of the number of PDCCH candidates. The calculation process is as follows:
when CCE resources are calculated, m s,nci PDCCH candidates only for the TCI state indicated for CORESET0 in the search space (in this example, PDCCH candidates 0-2 correspond to CORESET0, and PDCCH candidates 3-7 correspond to CORESET1, where m is the CCE resource of PDCCH candidate in CORESET0 when calculating the CCE resource of PDCCH candidate s,nci 0-2 in turn correspond to PDCCH candidates 0-2). N is a radical of hydrogen CCE,p The number of CCEs of CORESET corresponding to the candidate PDCCH.For all configured cells n in the search space s CI Only the maximum value of the candidate PDCCHs of aggregation level L configured for the terminal device by the CORESET0 is associated.
The terminal equipment determines CCE resources corresponding to each candidate PDCCH based on the number of the candidate PDCCHs associated with each CORESET indicated by the network equipment, and receives the detection PDCCH on the corresponding CCE resources.
Example 3:
the network device configures a Search Space associated with 2 CORESET.
The network device has only one TCI state activated at any one time for each CORESET.
The network device configures 8 PDCCH candidates for aggregation level 8 of Search Space, where one PDCCH candidate in the 8 PDCCH candidates is selected at time T0 and is transmitted by TCI state 0 indicated by core set 0. Selecting one of the 8 candidate PDCCHs at time T1 is performed by TCI state 1 indicated by CORESET1 to transmit downlink control information.
It should be noted that this example differs from example 1 in that: all 8 PDCCH candidates will be sent via CORESET0 and CORESET 1. The time T0 and the time T1 may be the same or different. If the two signals are the same, the PDCCH is transmitted twice through the TCI states indicated by CORESET0 and CORESET1 at time T0.
In addition, the determined PDCCH candidates may have the same or different CORESET pool index among the 8 PDCCH candidates. For example, the PDCCH candidate with CORESET pool index of 0 is chosen by CORESET0, and the PDCCH candidate with CORESET pool index of 1 is chosen by CORESET 1.
The network device sends the Search Space and one candidate PDCCH in the candidate PDCCHs corresponding to the TCI state indicated by the associated CORESET0 to the terminal device and indicates related downlink control information, wherein the indicated downlink control information can be used for scheduling a channel;
the network device sends the related downlink control information to the terminal device through the Search Space and one of the candidate PDCCHs corresponding to the TCI state indicated by the associated CORESET1, where the indicated downlink control information may be used to schedule a channel.
The PDCCHs respectively transmitted by the network device through TCI state 0 of CORESET0 and the network device through TCI state 1 of CORESET1 may be used to schedule the same channel, or may be used to schedule different channels.
When the same channel is scheduled, the network device may indicate, through pre-configuration or high-layer signaling, that there is some correspondence between the first 3 candidate PDCCHs and the last 5 candidate PDCCHs with an aggregation level of 8. That is, when the network device selects to transmit downlink control information through the ith candidate PDCCH of the first 3 candidate PDCCHs, the network device may transmit the same downlink control information through the same kth candidate PDCCH of the last 5 candidate PDCCHs. The two downlink control information schedules the same channel.
At time T0, the network device calculates CCE resources occupied by channels of the candidate PDCCH number based on only the number of candidate PDCCHs corresponding to TCI state 0 indicated by core Space 0 and the number of CCEs of core Space 0.
At time T1, the network device calculates the CCE resources occupied by the channels of the PDCCH candidates based on the PDCCH candidate number associated with TCI state 1 indicated by core set1 in the Search Space and the CCE number of core set 1.
And the network equipment selects a CCE resource occupied by one PDCCH from the CCE resources corresponding to the channels of the candidate PDCCH number calculated based on CORESET0 and TCI state 0 at the time T0 to transmit the downlink control information.
And the network equipment selects a CCE resource occupied by one PDCCH from the CCE resources corresponding to the channels of the candidate PDCCH number calculated based on CORESET1 and TCI state 1 at the time T1 to transmit the downlink control information.
The downlink control information transmitted by the PDCCH selected by the network device at the time T0 and T1 is the repeated transmission of one control channel.
The terminal equipment determines CCE resources corresponding to each candidate PDCCH based on the number of the candidate PDCCHs associated with each CORESET indicated by the network equipment, and receives the detection PDCCH on the corresponding CCE resources.
According to the transmission method of the channel resources provided by the embodiment of the application, the UE can detect the PDCCH on the correct resources by determining the resources of the PDCCH sent by each TCI state, so that the subsequent data is received or sent.
It should be noted that, in the transmission method of the channel resource provided in the embodiment of the present application, the association relationship between the SS, the core, the TCI state and the PDCCH candidate described in the above example may also be expressed as a corresponding relationship, and the implementation of the transmission method of the channel resource provided in the embodiment of the present application is not specifically limited.
