Description

Resource indication and detection method, equipment and storage medium for control channel

Technical Field

The present invention relates to the field of wireless communications technologies, and in particular, to a method, a device, and a storage medium for indicating and detecting a resource of a control channel.

Background

In an LTE (Long Term Evolution) system, when a PDCCH (Physical Downlink Control Channel) is transmitted, the entire system bandwidth is occupied in a Frequency domain, 1 to 3 OFDM (Orthogonal Frequency Division Multiplexing) symbols (for a case that a Downlink bandwidth is greater than 10 RBs (resource blocks) or 2 to 4 OFDM symbols (for a case that a Downlink bandwidth is less than or equal to 10 RBs) may be occupied in a time domain according to a difference of the system bandwidth, and 3 states are indicated by a Physical Control Format Indicator Channel (pcch)). The size of the PCFICH is 2 bits, wherein a Control Format Indicator (CFI) carried therein is used to indicate the number of symbols occupied by the PDCCH in the subframe.

In the LTE system, after accessing a system, a terminal obtains a current system bandwidth by reading an indication about a bandwidth in a PBCH (Physical Broadcast Channel), and then reads control Channel (PDCCH) information occupying a full bandwidth, determines a resource location of the control Channel, and transmits and receives user data according to the resource location of the control Channel.

In the design of the 5G system, the operating bandwidth of the terminal is supported to be different from the bandwidth of the network, that is, the terminal with the operating bandwidth smaller than the network bandwidth is supported to access the network. The transmission of the control channel of the corresponding terminal needs to be transmitted in a sub-band manner rather than in a full-bandwidth manner. At this time, if the resource locations of the control channels are indicated, directly indicating the resource locations of the control channels of any number and location would bring a large indication overhead, and at the same time, the number of blind detections for the control channels by the terminal is also increased.

Therefore, it is necessary to design an indication mode with less resource location indication overhead of the control channel to reduce the number of blind detections for the control channel by the terminal.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, are within the scope of the invention.

Referring to fig. 1, fig. 1 is a flowchart illustrating a method for indicating resources of a control channel according to an embodiment of the present invention, where the method is used in a network side device, and includes:

step 11: determining indication information of a resource location of a control channel or a control channel resource set used for transmitting control information to a terminal; the minimum granularity adopted by the resource position indication is the bandwidth used by the transmission of a physical broadcast channel, a main synchronization sequence, an auxiliary synchronization sequence or a physical downlink shared channel, or the number of resource blocks corresponding to the bandwidth used by the transmission of the physical broadcast channel, the main synchronization sequence, the auxiliary synchronization sequence or the physical downlink shared channel, or the number of preset bandwidths or resource blocks;

the Control channel resource set (CORESET for short) refers to a time-frequency resource for carrying a Control channel, and includes a plurality of RBs in a frequency domain and one or more OFDM symbols in a time domain.

Step 12: indicating information to the terminal through a Physical Broadcast Channel (PBCH) and/or a Physical Downlink Shared Channel (PDSCH).

Specifically, when the indication information is indicated to the terminal by using a physical broadcast channel, the minimum granularity used for the resource location indication may be one of bandwidths used for transmission of the physical broadcast channel, the primary synchronization sequence, the secondary synchronization sequence, or the physical downlink shared channel, or one of resource block numbers corresponding to the bandwidths used for transmission of the physical broadcast channel, the primary synchronization sequence, the secondary synchronization sequence, or the physical downlink shared channel, or a predetermined bandwidth or resource block number.

When the physical downlink shared channel is used to indicate the indication information to the terminal, the minimum granularity used by the resource location indication may also be one of the bandwidths used for transmission of the physical broadcast channel, the primary synchronization sequence, the secondary synchronization sequence, or the physical downlink shared channel, or one of the resource block numbers corresponding to the bandwidths used for transmission of the physical broadcast channel, the primary synchronization sequence, the secondary synchronization sequence, or the physical downlink shared channel, or a predetermined bandwidth or resource block number.

When the minimum granularity adopted by the resource position indication is the bandwidth used for the transmission of the physical downlink shared channel or the number of resource blocks corresponding to the bandwidth used for the transmission of the physical downlink shared channel, and the physical downlink shared channel is adopted to indicate the indication information to the terminal, the physical downlink shared channel used for defining the minimum granularity is the downlink shared channel used for bearing the indication information.

The network side device in the embodiment of the present invention may be a Base Transceiver Station (BTS) in Global System for Mobile communication (GSM) or Code Division Multiple Access (CDMA), may also be a Base Station (NodeB, NB) in Wideband Code Division Multiple Access (WCDMA), may also be an evolved Node B (evolved Node B, eNB or eNodeB) in LTE, or a relay Station or Access point, or a Base Station in a future 5G network, and the like, which is not limited herein.

For example, devices such as Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs) are used. A wireless Terminal may also be referred to as a system, a Subscriber Unit (Subscriber Unit), a Subscriber Station (Subscriber Station), a Mobile Station (Mobile), a Remote Station (Remote Station), a Remote Terminal (Remote Terminal), an Access Terminal (Access Terminal), a User Terminal (User Terminal), a User Agent (User Agent), and a Terminal (User Device or User Equipment), which are not limited herein.

The current 3GPP discussion concludes that part of the system required information is transmitted through PBCH and the rest of the system required information is carried through PDSCH. Therefore, preferably, in the embodiment of the present invention, the indication information of the resource location of the control channel or the control channel resource set for scheduling part of the system essential information may be transmitted through the PBCH, and the indication information of the resource location of the control channel or the control channel resource set for scheduling the common control information (i.e., the remaining system essential information) may be transmitted through the PDSCH.

In this embodiment of the present invention, the indication information indicates an absolute position of the resource position in the entire system bandwidth, or a relative position of the resource position with respect to the physical broadcast channel or the physical downlink shared channel.

The following describes the minimum granularity employed for resource location indication.

The minimum granularity a may be measured in terms of bandwidth or in terms of the number of Resource Blocks (RBs).

In some preferred embodiments of the present invention, a may be a bandwidth used for PBCH, PSS (primary synchronization sequence), SSS (secondary synchronization sequence), or PDSCH transmission, or a number of resource blocks corresponding to the bandwidth used for PBCH, PSS, SSS, or PDSCH transmission.

In some other embodiments of the present invention, a may also be a predetermined bandwidth or number of resource blocks.

In the embodiment of the present invention, the indication information of the resource location of the control channel or the control channel resource set may be indicated in various ways, which is described below by way of example.

In a preferred embodiment of the present invention, the resource position of the control channel or the control channel resource set may be indicated by a Resource Indication Value (RIV), and the RIV value can simultaneously represent a starting position RA of the resource position of the control channel or the control channel resource set_startAnd the number L of consecutive A's contained in the resource location of the control channel or control channel resource set. Different starting positions RA_startDifferent L, correspond to different resource indication values RIV. Wherein L is largeA positive integer equal to or greater than 1.

In consideration of the complexity of resource indication, in the embodiment of the present invention, when the resource location of the control channel or the control channel resource set contains L a, L a are consecutive, and L is a positive integer greater than or equal to 1.

That is, the step of determining the indication information of the resource location of the control channel or the control channel resource set used for transmitting the control information to the terminal may include: determining a resource indicated value corresponding to the resource position according to the minimum granularity adopted by the resource position indication, the initial position of the resource position and the number of continuous minimum granularities contained in the resource position; and generating the indication information of the resource position according to the resource indication value.

The initial position of the resource position is an initial position of the resource position in a partial or full system bandwidth, where the initial position of the resource position in the partial or full system bandwidth may be determined according to a position of the physical broadcast channel or the physical downlink shared channel, that is, a reference bandwidth used for calculating a resource indication value of the resource position.

When the indication information indicates the absolute position of the resource position in the whole system bandwidth, the starting position of the resource position is the starting position of the resource position in the system bandwidth;

when the indication information indicates the relative position of the resource position with respect to the physical broadcast channel or the physical downlink shared channel, the starting position of the resource position is the starting position of the resource position in a part or the whole system bandwidth.

In this embodiment of the present invention, the resource indication value may be determined by using the following formula:

when in use

When RIV is equal to N_A(L-1)+RA_start

Otherwise, RIV ═ N_A(N_A-L+1)+(N_A-1-RA_start)

Wherein RIV is a resource indication value, A is a minimum granularity adopted by the resource position indication, N_AThe number of A's, N's, contained for part or all of the system bandwidth_AIs a positive integer greater than or equal to 1, RA_startIs the starting position of the resource position, L is the number of continuous A contained in the resource position, and L is a positive integer greater than or equal to 1. When the indication information indicates the absolute position of the resource position in the whole system bandwidth, N_AThe number of A contained in the system bandwidth;

when the relative position of the resource position relative to the physical broadcast channel or the physical downlink shared channel is indicated in the indication information, N_AIs the number of a's contained in the partial or full system bandwidth.

When the RIV value is calculated by adopting the bandwidth of the whole system and A adopts bandwidth measurement, the number of A contained in the bandwidth of the whole system is

B is system bandwidth, when A is measured by resource block, the number of A contained in the whole system bandwidth is

N_BThe number of resource blocks corresponding to the whole system bandwidth is M, and the number of resource blocks corresponding to the bandwidth used for transmission of PBCH, PSS, SSS or PDSCH is M.

When the RIV value is calculated by adopting partial system bandwidth and A adopts bandwidth measurement, the number of A contained in the whole system bandwidth is

B is partial system bandwidth, when A is measured by resource block, the number of A contained in partial system bandwidth is

N_BThe number of resource blocks corresponding to part of system bandwidth is M, and M is the number of resource blocks corresponding to the bandwidth used by PBCH, PSS, SSS or PDSCH transmission.

Referring to fig. 2, fig. 2 is a schematic diagram illustrating a method for determining a resource indication value according to an embodiment of the present invention, and it can be seen from fig. 2 that different initial positions RA_startDifferent L, correspond to different resource indication values RIV.

As can be seen from the above RIV calculation formula, when calculating RIV, it is necessary to know N for calculating RIV_ATherefore, when the terminal receives the indication information RIV, it needs to know N_ACan be based on RIV and N_AObtaining RA_startAnd the value of L, thereby determining the resource location of the control channel or set of control channel resources.

In some embodiments of the present invention, when the indication information indicates an absolute location of the resource location in the entire system bandwidth, the network side device may further indicate the system bandwidth to the terminal. The system bandwidth may be indicated to the terminal by, for example, broadcast information. When the terminal can obtain the system bandwidth, the number N of A contained in the system bandwidth can be obtained_AThus, the resource location of the control channel or control channel resource set can be derived from the value of the RIV.

In some other embodiments of the present invention, when the indication information indicates the relative position of the resource location with respect to the physical broadcast channel or the physical downlink shared channel, the network side device may further determine the number N of a in a partial or entire system bandwidth to which the indication information applies_AAnd indicating the position of the physical broadcast channel or the physical downlink shared channel in the partial or the whole system bandwidth to the terminal.

For example, a is the bandwidth used in the transmission of the physical broadcast channel, a is 1, the system bandwidth is 10, the number of a included in the system bandwidth is 10, the resource locations of the control channel or the control channel resource set include L consecutive a, L is 2, and the number N of a included in the partial system bandwidth for calculating the RIV is N_AAt 6, the physical broadcast channel is at position 3 in the partial system bandwidth, the starting position RA of the resource location_startIs 4, the resource locationRIV equal to RIV-N_A(L-1)+RA_start＝6(2-1)+4＝10。

The network side device may use indication information RIV (i.e. 10), the number N of a in the partial system bandwidth to which the indication information applies_A(i.e., 6), and the location of the physical broadcast channel in the portion of the system bandwidth (i.e., 3) is indicated to the terminal.

The terminal can indicate the number N of A in the partial system bandwidth to which the information is applicable according to the value of the RIV_AAnd the position of the physical broadcast channel in the partial system bandwidth, determining the starting position RA of the resource location_startAnd the number L of A contained in the resource position, thereby determining the resource position.

In some other embodiments of the present invention, when the indication information indicates the relative position of the resource location with respect to the physical broadcast channel or the physical downlink shared channel, the network side device may further determine the number N of a in a partial or entire system bandwidth to which the indication information applies_AAnd a relative position of the resource position of the control channel or the control channel resource set indicated by the indication information with respect to the physical broadcast channel or the physical downlink shared channel (i.e. information indicating whether the resource position of the control channel or the control channel resource set indicated by the indication information is located before or after the physical broadcast channel or the physical downlink shared channel) is indicated to the terminal.

In this embodiment of the present invention, the partial system bandwidth used by the indication information refers to a partial system bandwidth before or after the physical broadcast channel or the physical downlink shared channel in the entire system bandwidth, if the resource location is located before the physical broadcast channel or the physical downlink shared channel, the partial system bandwidth used by the indication information refers to a partial system bandwidth before the physical broadcast channel or the physical downlink shared channel in the entire system bandwidth, and if the resource location is located after the physical broadcast channel or the physical downlink shared channel, the partial system bandwidth used by the indication information refers to a partial system bandwidth after the physical broadcast channel or the physical downlink shared channel in the entire system bandwidth.

When the physical broadcast channel or the physical downlink shared channel is located at the edge of the entire system bandwidth, the system bandwidth used by the indication information may refer to the entire system bandwidth.

In an embodiment of the present invention, it is assumed that the indication information of the resource location of the control channel or the control channel resource set is indicated to the terminal by PBCH. Based on the whole system bandwidth, a granularity a of resource indication is defined, that is, the minimum granularity adopted by the resource location indication of the control channel or the control channel resource set is a, and a may be measured by the bandwidth or the number of resource blocks. Preferably, a may be a bandwidth used for PBCH, PSS or SSS transmission, or a number of resource blocks corresponding to the bandwidth used for PBCH, PSS or SSS transmission.

Considering that the minimum bandwidth of the PBCH is 5MHz (may also be 10MHz, 40MHz, 80MHz, etc.), when the resource location of the control channel or the control channel resource set includes bandwidths of multiple PBCHs, since the frequency selective gain of the distributed multiple subbands is limited, and the complexity of resource location indication is considered, when the resource location of the control channel or the control channel resource set includes L a, L a are consecutive.

In the embodiment of the invention, the resource position of the control channel or the resource assembly of the control channel adopts a resource indication value RIV indication which can represent the initial position RA of the resource position in the system bandwidth at the same time_startAnd the number L of consecutive A's contained in the resource location. I.e. different starting positions RA_startDifferent L, correspond to different resource indication values RIV.

The resource indication value RIV can be calculated by adopting the following formula:

when in use

When RIV is equal to N_A(L-1)+RA_start

Otherwise, RIV ═ N_A(N_A-L+1)+(N_A-1-RA_start)

Wherein N is_AThe number of a's contained in the system bandwidth.

When the terminal can obtain the system bandwidth, N can be obtained_AThus, the resource location of the control channel or control channel resource set can be derived from the value of the RIV.

In the above embodiment, the indication information is indicated to the terminal through the PBCH, and of course, the above method may also be adopted when the PDSCH is used to transmit the indication information to the terminal, and will not be described in detail here.

It can be understood that, from the perspective of reducing the indication overhead of the resource location, the smaller the value of the number L of a included in the resource location of the control channel or the control channel resource set, the smaller the indication overhead of the resource location, and therefore, in an embodiment of the present invention, the L may be set to be less than or equal to a preset threshold, and the preset threshold may be set as needed, for example, may be set to be 2.

In the embodiment of the present invention, it is assumed that the number N of A included in the system bandwidth_AIf a bitmap mode is adopted for indicating a in the resource position, the indication information needs 10 bits, and by the above-mentioned RIV indication mode, the RIV takes values from 0 to 54, and only 6 bits are needed, thereby effectively reducing the resource position indication overhead of the control channel or the control channel resource set.

In some other preferred embodiments of the present invention, the resource location of the control channel or the control channel resource set may also be indicated by means of a combined index.

In the embodiment of the present invention, a granularity of a resource indication, that is, a minimum granularity used for resource location indication of a control channel or a control channel resource set may be defined first, and the minimum granularity may be measured by a bandwidth or may be measured by a number of resource blocks. Preferably, the minimum granularity may be a bandwidth used for PBCH, PSS, SSS, or PDSCH transmission, or a number of resource blocks corresponding to the bandwidth used for PBCH, PSS, SSS, or PDSCH transmission.

When a resource location of a control channel or a control channel resource set includes multiple minimum granularities, a combined index of all the minimum granularities in the resource location may be determined, and indication information of the resource location may be generated according to the combined index of all the minimum granularities in the resource location.

The indication mode of the combined index is suitable for the condition that the resource position of the control channel or the control channel resource set comprises a plurality of continuous minimum granularities, is also suitable for the condition that the resource position comprises a plurality of discontinuous minimum granularities, and has wider application range.

In the embodiment of the invention, the index of each minimum granularity A in the system broadband can adopt 0 to (N)_A-1) represents, wherein N_AIs the number of A included in part or all of the system bandwidth, and the index of each A is

Wherein, the combination index r of L a in the resource positions of the control channel or the control channel resource set can be represented as:

wherein A is the minimum granularity adopted by the resource position indication, N_AThe number of A's, N's, contained for part or all of the system bandwidth_AIs a positive integer greater than or equal to 1, L is the number of A in the resource location, L is a positive integer greater than or equal to 1, k_iDenotes the number of the ith A of the L A,

thus, the value of r is unique, and the value range is as follows:

in the embodiment of the invention, L is assumed to be 2, N_AIn the case of 10, the combination index r is used to indicate

For 45 states in total, 6 bits are needed for indication, while if only 2 continuous A conditions are assumed, only 9 states are needed, and 4 bits are needed for indication.

In an embodiment that a combined index indication is adopted, when the indication information indicates an absolute position of the resource position in the entire system bandwidth, the network side device may further indicate the system bandwidth to the terminal. The system bandwidth may be indicated to the terminal by, for example, broadcast information. When the terminal can obtain the system bandwidth, the number N of A contained in the system bandwidth can be obtained_AAnd thus the resource location of the control channel or the control channel resource set can be obtained according to the combination index.

In an embodiment that employs combination index indication, when the indication information indicates a relative position of the resource location with respect to the physical broadcast channel or the physical downlink shared channel, the network side device may further determine the number N of a in a partial or entire system bandwidth to which the indication information applies_AAnd indicating the position of the physical broadcast channel or the physical downlink shared channel in the partial or the whole system bandwidth to the terminal.

In an embodiment that employs combination index indication, when the indication information indicates a relative position of the resource position with respect to the physical broadcast channel or the physical downlink shared channel, the network side device may further apply the indication information to the number N of a in a partial or entire system bandwidth_AAnd a relative position of the resource position of the control channel or the control channel resource set indicated by the indication information with respect to the physical broadcast channel or the physical downlink shared channel (i.e. information indicating whether the resource position of the control channel or the control channel resource set indicated by the indication information is located before or after the physical broadcast channel or the physical downlink shared channel) is indicated to the terminal.

For example, a is a bandwidth used in the transmission of the physical broadcast channel, which is 1, a system bandwidth is 10 (0-9), the physical broadcast channel is located at 4, and the resource location is located after the physical broadcast channel, which has 5 a after the physical broadcast channel, and at this time, the location of the resource location in the last 5 a may be indicated by using a combined index.

In other embodiments of the present invention, a bitmap may be used to indicate the resource location of the control channel or the control channel resource set.

That is, the step of determining the indication information of the resource location of the control channel or the control channel resource set used for transmitting the control information to the terminal may include:

determining bitmap information of the resource position according to the minimum granularity adopted by the resource position indication and the absolute position of the resource position in the whole system bandwidth or the relative position of the resource position relative to the physical broadcast channel or the physical downlink shared channel;

and generating the indication information of the resource position according to the bitmap information.

Similarly, when the indication information indicates an absolute position of the resource position in the entire system bandwidth, the network side device may further indicate the system bandwidth to the terminal. The system bandwidth may be indicated to the terminal by, for example, broadcast information. When the terminal can obtain the system bandwidth, the number N of A contained in the system bandwidth can be obtained_AAnd thus the resource location of the control channel or the control channel resource set can be obtained according to the combination index.

For example, a is a bandwidth used in the transmission of the physical broadcast channel, which is 1, a system bandwidth is 10(0 to 9), the physical broadcast channel is located at 4, the resource location is located after the physical broadcast channel, which has 5 a behind the physical broadcast channel, and at this time, the location of the resource location in the last 5 a can be indicated by using a bitmap method.

In the 5G system, the terminal types have diversity, and therefore, different types of terminals may be preferably allocated with different resource locations of control channels or control channel resource sets to facilitate detection of control information by the terminals. Correspondingly, in the embodiment of the present invention, the network side device may determine, according to a correspondence between the type of the terminal and a resource location of a control channel or a control channel resource set used by the terminal to transmit the control information, indication information of the resource location of the control channel or the control channel resource set used by the terminal to transmit the control information, where the indication information includes at least one resource location, and different types of terminals correspond to the same or different resource locations.

Preferably, the network side device further needs to indicate the correspondence between the type of the terminal and the resource location of the control channel or the control channel resource set used by the terminal for transmitting the control information to the terminal.

Preferably, the types of the terminal include: terminals supporting different system parameters, terminals having different operating bandwidth capabilities, terminals having different service types or terminals having different beam directions.

Referring to fig. 3, an embodiment of the present invention further provides a method for detecting resources of a control channel, which is used for a terminal, and includes:

step 31: receiving indication information of a resource position of a control channel or a control channel resource set used by a network side device for transmitting control information to a terminal through a physical broadcast channel and/or a physical downlink shared channel, wherein the minimum granularity adopted by the resource position indication is the bandwidth used by the transmission of the physical broadcast channel, a main synchronization sequence, an auxiliary synchronization sequence or the physical downlink shared channel, or the number of resource blocks corresponding to the bandwidth used by the transmission of the physical broadcast channel, the main synchronization sequence, the auxiliary synchronization sequence or the physical downlink shared channel, or the number of the predetermined bandwidth or resource blocks;

step 32: and determining the resource position according to the indication information.

In this embodiment of the present invention, preferably, after the step of determining the location of the resource, the method further includes:

and detecting the control information according to the resource position.

In some embodiments of the present invention, the indication information includes a resource indication value, where the resource indication value is determined according to a minimum granularity adopted by the resource location indication, a starting position of the resource location, and a number of consecutive minimum granularities included in the resource location, where the starting position of the resource location is a starting position of the resource location in a system bandwidth, or a starting position of the resource location in a partial or entire system bandwidth; the step of determining the resource location according to the indication information comprises: and determining the resource position of the control channel or the control channel resource set according to the resource indication value.

Preferably, the resource indication value is determined by the following formula:

when in use

When RIV is equal to N_A(L-1)+RA_start

Otherwise, RIV ═ N_A(N_A-L+1)+(N_A-1-RA_start)
