The present application relates to the field of wireless communications technologies, and in particular, to an information configuration method and apparatus, and a communication device.

Background

Currently, third generation partnership organizations (3rd Generation Partnership Project,3GPP) are planning for standardization work of intelligent repeater (network controlled repeater). For the intelligent repeater, in the downlink direction, a Time division multiplexing (Time-Division Multiplexing, TDM) mode is adopted to receive a control signal dedicated to the repeater and a downlink signal of the terminal. If the intelligent repeater keeps using the search space of the terminal, the intelligent repeater can not work in a TDM mode. On the other hand, the intelligent repeater may only be able to receive one or a few beams transmitted by the base station, and then the intelligent repeater may only be able to receive one or a few beams inside the burst (SSB) in each synchronization signal Block (SS/PBCH Block, SSB) period. In order to realize full coverage of the intelligent repeater, a plurality of SSB periods are needed to complete one round of full coverage, so that the actual SSB period of the terminal covered by the actual intelligent repeater is prolonged and is larger than that of a common terminal.

Detailed Description

The following description of the technical solutions according to the embodiments of the present application will be given with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

In order to facilitate understanding of the technical solutions of the embodiments of the present application, the following description describes related technologies of the embodiments of the present application, and the following related technologies may be optionally combined with the technical solutions of the embodiments of the present application as alternatives, which all belong to the protection scope of the embodiments of the present application.

In order for the network to provide better coverage capability, especially for the case of FR2, the millimeter wave signals of FR2 are easily shielded by vegetation and buildings, and more flexible and reliable coverage enhancement techniques are needed. Related schemes propose and standardize intelligent repeater (network controlled repeater) technology.

Fig. 1 is a schematic diagram of an application scenario of an embodiment of the present application, as shown in fig. 1, an intelligent repeater is located between a base station and a terminal, and compared with a conventional repeater, the intelligent repeater has a beam management function, and a standardized objective is that the intelligent repeater can be transparent to the terminal.

Fig. 2 is a radio frequency architecture diagram of an intelligent repeater according to an embodiment of the present application, where, as shown in fig. 2, a left antenna is a donor (donor) antenna, the donor antenna refers to an antenna facing a base station, a right antenna is an access (access) antenna, and the access antenna refers to an antenna facing a terminal (UE). The intelligent repeater is provided with three radio frequency links, namely a first link, a second link and a third link from top to bottom. The first link is responsible for receiving the control signal from the base station (needing to demodulate the control signal), the second link is responsible for receiving the downlink signal from the base station and amplifying and forwarding to the terminal (needing not to demodulate the downlink signal), and the third link is responsible for receiving the uplink signal from the terminal and amplifying and forwarding to the base station (needing not to demodulate the uplink signal). The intelligent repeater (specifically, a baseband processor) controls the backhaul link switch and the access link switch according to the control information demodulated from the control signal to determine which link is accessed, wherein in the downlink direction, the intelligent repeater receives the control signal dedicated to the repeater and the downlink signal of the terminal in a TDM manner. For example: if the base station issues a dedicated control message of the intelligent repeater, the intelligent repeater connects the first link with the donor antenna; if the base station sends a downlink message (including downlink control information and downlink data information) to the terminal, the intelligent repeater connects the second link with the donor antenna; if the terminal sends an uplink message (including uplink control information and uplink data information) to the base station, the intelligent repeater connects the third link with the access antenna.

On the one hand, if the intelligent repeater uses the search space of the terminal and uses the same search space configuration as the terminal, the intelligent repeater cannot work in a TDM manner, and cannot amplify and forward the downlink signal of the terminal or cannot demodulate the dedicated control signal of the repeater. On the other hand, as shown in fig. 3, the intelligent repeater may only receive one beam sent by the base station, and in each SSB period, the intelligent repeater may only receive one beam in burst, and in order to implement full coverage of the intelligent repeater, multiple SSB periods are required to complete full coverage of the repeater, so that the SSB period of the terminal covered by the actual repeater is prolonged.

For this reason, the following technical solutions of the embodiments of the present application are provided. According to the technical scheme provided by the embodiment of the application, on one hand, how to set the proper exclusive search space of the repeater is considered, so that the exclusive control signal of the repeater is ensured to be distinguished from the downlink signal (comprising downlink control information and downlink data information) of the terminal in the time domain. In particular, when implementing, the distinction between the dedicated control signal of the repeater and the downlink signal of the terminal can be achieved through base station scheduling, so that the physical downlink control channel (Physical Downlink Control Channel, PDCCH) resource of the repeater and the PDCCH resource of the terminal need to be distinguished. On the other hand, consider how to set an appropriate SSB dedicated to the repeater, so as to solve the problem that the SSB period of the terminal under the coverage of the repeater is too long.

In order to facilitate understanding of the technical solution of the embodiments of the present application, the technical solution of the present application is described in detail below through specific embodiments. The above related technologies may be optionally combined with the technical solutions of the embodiments of the present application, which all belong to the protection scope of the embodiments of the present application. Embodiments of the present application include at least some of the following.

It should be noted that, in the embodiment of the present application, the description about "repeater" may be replaced by other names, for example, may be replaced by an intelligent repeater, a network control repeater, an intelligent relay, etc. The English name can be smart repeat or network controlled repeater, etc.

Fig. 4 is a flow chart of an information configuration method according to an embodiment of the present application, as shown in fig. 4, where the information configuration method includes:

step 401: the base station transmits configuration information, and the repeater receives the configuration information transmitted by the base station, wherein the configuration information comprises at least one of the following components: the method comprises the steps of configuring a first SSB period, indicating information of a first SSB index and configuring a first search space, wherein the first SSB period is an exclusive SSB period of the repeater, and the first search space is an exclusive search space of the repeater.

In the embodiment of the present application, the configuration information is carried in a system message sent by the base station, where the configuration information may also be understood as system configuration information. Or, the configuration information is carried in an RRC message.

In the embodiment of the present application, the configuration information obtained by the repeater includes at least one of the following: the configuration of a first SSB period, the configuration of first SSB index indication information and the configuration of a first search space, wherein the first SSB period is an SSB period exclusive to the repeater, and the first search space is a search space exclusive to the repeater (or an additional SSB period exclusive to the repeater). Here, the first SSB period and/or the first search space are used for the repeater to receive the control signal dedicated to the repeater sent by the base station.

Configuration for SSB cycles

In the embodiment of the present application, the configuration information includes a configuration of the first SSB period. The configuration of the first SSB period may be a duration of the first SSB period, which is used to represent the SSB period exclusive to the repeater. In some optional embodiments, the configuration information further includes a configuration of a second SSB period, where the second SSB period is an SSB period of the terminal, and M is a positive integer, and M is M times the first SSB period. Alternatively, the configuration of the first SSB period may be a scale factor of 1/M, where M is a positive integer, to indicate that the first SSB period is 1/M of the second SSB period.

Configuration of index indication information with respect to a first SSB

In an embodiment of the present application, the configuration information includes first SSB index indication information, where the first SSB index indication information is used to indicate an index value of SSB included in a group of SSB bursts (SSB bursts); the first SSB index indication information is dedicated indication information of the repeater and is only applicable to the first SSB period (i.e., the first SSB index indication information is dedicated SSB index indication information of the repeater); or the first SSB index indication information is indication information shared by the repeater and the terminal and is applicable to the first SSB period and the second SSB period (i.e. the first SSB index indication information may multiplex the SSB index indication information of the existing terminal, but change the meaning thereof).

Here, the first SSB index indication information may be referred to as "SSB-disposition infurst", and the total bit number of the first SSB index indication information is denoted by L, that is, the maximum number of SSBs allowed in SSB bursts is L, where each first SSB period includes only one group of SSB bursts. The specific meaning of the SSB index indication information may be implemented as follows:

case one

Each first SSB period includes a set of SSB bursts, where the SSB index indication information has the following meaning: if the first SSB index indicates the n-th position 1 of the information, it indicates that SSB with index value n or n-1 is included in a group of SSB bursts in each first SSB period, where n is a positive integer.

Specifically, taking the first SSB index indication information as SSB-locationinburst, the first SSB period as the SSB period of the repeater, the second SSB period as the SSB period of the terminal, for example, the repeater receives a group of SSB bursts in each SSB period of the repeater, the SSB contained in each group of SSB bursts is indicated by SSB-locationinburst, the value range of the index value of the SSB is 1,2 … L or 0,1 … L-1, and if the nth position 1 of the SSB-locationinburst, the SSB containing the SSB with the index value of n or n-1 is indicated in the SSB burst.

As an example: the SSB period of the repeater is denoted by N, the SSB period of the terminal is denoted by T, and the value of T can be referred to the current standard. The SSB period of the terminal is M times that of the SSB period of the repeater, i.e., T/n=m. L=4, SSB-positioning inburst=1001, t=20ms, n=5ms, then the repeater receives a group of SSB bursts every 5ms, each group of SSB bursts contains 2 SSBs, and the index value is 1,4 or 0,3 respectively.

Case two

Each first SSB period includes a set of SSB bursts, where, in a case where a maximum number L of SSBs allowed in the SSB bursts is equal to M:

option 1) the meaning of the first SSB index indication information is: if the first SSB index indicates the n-th position 1 of the information, it indicates that SSB with index value n or n-1 is included in a group of SSB bursts in each first SSB period, where n is a positive integer.

Specifically, taking the first SSB index indication information as SSB-locationinburst, the first SSB period as the SSB period of the repeater, and the second SSB period as the SSB period of the terminal as an example, when the allowed maximum SSB number L in the SSB burst is equal to M, the SSB number in the SSB burst received by the repeater in each SSB period is the same as the number of SSB-locationinburst 1, and the n-th position 1 in the SSB-locationinburst represents SSB with index value n or n-1 in the SSB burst.

As an example: the SSB period of the repeater is denoted by N, the SSB period of the terminal is denoted by T, and the value of T can be referred to the current standard. The SSB period of the terminal is M times that of the SSB period of the repeater, i.e., T/n=m, and the maximum SSB number L allowed in the SSB burst is equal to M (i.e., T/N). L=4, SSB-positioning inburst=1001, t=20ms, n=5ms, then the repeater receives a group of SSB bursts every 5ms, each group of SSB bursts contains 2 SSBs, and the index value is 1,4 or 0,3 respectively.

Option 2) the meaning of the first SSB index indication information is: if the first SSB index indicates the n-th position 1 of the information, it indicates that 1 SSB is included in a group of SSB bursts in the corresponding n-th first SSB period in each second SSB period, and the index value is n or n-1, n is a positive integer.

Specifically, taking the first SSB index indication information as SSB-locationinburst, the first SSB period as the SSB period of the repeater, and the second SSB period as the SSB period of the terminal as an example, when the maximum allowed SSB number L in the SSB burst is equal to M, the repeater only includes 1 SSB in the SSB burst received in each SSB period of the repeater, the nth position 1 in the SSB-locationinburst represents that 1 SSB is included in the corresponding nth repeater period in each SSB period of the terminal, and the index value is n or n-1.

As an example: the SSB period of the repeater is denoted by N, the SSB period of the terminal is denoted by T, and the value of T can be referred to the current standard. The SSB period of the terminal is M times that of the SSB period of the repeater, i.e., T/n=m, and the maximum SSB number L allowed in the SSB burst is equal to M (i.e., T/N). L=4, SSB-positioning inburst=1001, t=20 ms, n=5 ms, then the repeater receives a set of SSB bursts every 5ms, the first 5ms within 20ms receives a set of SSB bursts containing an SSB with an index value of 1 or 0, and the fourth 5ms receives a set of SSB bursts containing an SSB with an index value of 4 or 3.

Option 3) the meaning of the first SSB index indication information is: if the first SSB index indicates the nth position 1 of the information, it indicates that 1 SSB is included in a group of SSB bursts in the nth first SSB period corresponding to each second SSB period, the index value is a fixed value, and n is a positive integer.

Specifically, taking the first SSB index indication information as SSB-locationinburst, the first SSB period as the SSB period of the repeater, the second SSB period as the SSB period of the terminal, and if the allowed maximum SSB number L in the SSB burst is equal to M, the SSB burst received by the repeater in each SSB period of the repeater only includes 1 SSB, the n-th position 1 in the SSB-locationinburst represents that the corresponding n-th repeater period in each SSB period of the terminal includes 1 SSB, and the index value is a fixed value.

As an example: the SSB period of the repeater is denoted by N, the SSB period of the terminal is denoted by T, and the value of T can be referred to the current standard. The SSB period of the terminal is M times that of the SSB period of the repeater, i.e., T/n=m, and the maximum SSB number L allowed in the SSB burst is equal to M (i.e., T/N). L=4, SSB-positioning inburst=1001, t=20 ms, n=5 ms, then the repeater receives a set of SSB bursts every 5ms, the first 5ms within 20ms receives a set of SSB bursts containing an SSB with an index value of 2 (fixed value), and the fourth 5ms receives a set of SSB bursts containing an SSB with an index value of 2 (fixed value).

Case three

Each first SSB period includes a set of SSB bursts, where K is a positive integer when a maximum number L of SSBs allowed in the SSB bursts is equal to K times M:

Option 1) the meaning of the SSB index indication information is: if the first SSB index indicates the n-th position 1 of the information, it indicates that SSB with index value n or n-1 is included in a group of SSB bursts in each first SSB period, where n is a positive integer.

Specifically, taking the first SSB index indication information as SSB-locationinburst, the first SSB period as the SSB period of the repeater, and the second SSB period as the SSB period of the terminal as an example, when the maximum SSB number L allowed in the SSB burst is equal to K times of M, each repeater period contains a group of SSB bursts, the number of SSB contained in each group of SSB bursts is the same as the number of SSB-locationinburst 1, and the n-th position 1 in the SSB-locationinburst represents SSB with index value n or n-1 contained in the SSB burst.

As an example: the SSB period of the repeater is denoted by N, the SSB period of the terminal is denoted by T, and the value of T can be referred to the current standard. The SSB period of the terminal is M times that of the SSB period of the repeater, i.e., T/n=m, and the maximum SSB number L allowed in the SSB burst is equal to K times that of M (i.e., K (T/N)). L=4, SSB-positioning inburst=1001, t=20ms, n=10ms, then the repeater receives a group of SSB bursts every 10ms, containing 2 SSBs in total, with index values of 1,4 or 0,3, respectively.

Option 2) the meaning of the first SSB index indication information is: and dividing all bit numbers L of the first SSB index indication information into M groups, wherein each group contains K-bit data, the kth group in the M groups corresponds to the kth first SSB period in each second SSB period, and if the nth position 1 in the first SSB index indication information indicates that SSB with an index value x is contained in one group of SSB bursts in the first SSB period corresponding to the nth position. The value of x is an index value obtained by sequencing all bits in the first SSB index indication information. Or the value of x is an index value obtained by sequencing all bits in the first SSB index indication information, and then K is modulo-obtained.

Specifically, taking the first SSB index indication information as SSB-locationinburst, the first SSB period as the SSB period of the repeater, and the second SSB period as the SSB period of the terminal as an example, dividing all bits in the SSB-locationinburst into M groups, wherein each group comprises K bits, the kth group in the SSB-locationinburst corresponds to the kth repeater SSB period in each terminal SSB period, and the number of SSBs contained in the corresponding SSB burst is the same as the number of the kth group 1, wherein the nth position 1 in the SSB-locationinburst represents the SSB of the corresponding repeater with the SSB index value x. As one implementation, x refers to an index value obtained by sequencing all bits in ssb-PositionInBurst, and specifically takes the value of 1,2 … L or 0,1 … L-1. As another implementation, x refers to an index number obtained by sequencing all digits in ssb-PositionInBurst, and then taking a modulus to obtain the specific value of 1,2 … T/N or 0,1 … T/N-1.

As an example: the SSB period of the repeater is denoted by N, the SSB period of the terminal is denoted by T, and the value of T can be referred to the current standard. The SSB period of the terminal is M times that of the SSB period of the repeater, i.e., T/n=m, and the maximum SSB number L allowed in the SSB burst is equal to K times that of M (i.e., K (T/N)). L=8, SSB-positnburst=1001, 1111, t=20ms, n=10ms, k=4, the SSB-positnburst is divided into two groups, the first group corresponding to a first repeater SSB period within 20ms and the second group corresponding to a second repeater SSB period within 20 ms. The repeater receives a set of SSB bursts every 10ms, the first 10ms of each 20ms receives a set of SSB bursts with two SSBs having indexes 1,4 or 0,3, respectively, and the second 10ms receives a set of SSB bursts with four SSBs having indexes 4,5,6,7 or 5,6,7,8, respectively.

As an example: the SSB period of the repeater is denoted by N, the SSB period of the terminal is denoted by T, and the value of T can be referred to the current standard. The SSB period of the terminal is M times that of the SSB period of the repeater, i.e., T/n=m, and the maximum SSB number L allowed in the SSB burst is equal to K times that of M (i.e., K (T/N)). L=8, SSB-positnburst=1001, 1111, t=20ms, n=10ms, k=4, the SSB-positnburst is divided into two groups, the first group corresponding to a first repeater SSB period within 20ms and the second group corresponding to a second repeater SSB period within 20 ms. The repeater receives a set of SSB bursts every 10ms, the first 10ms of each 20ms receives a set of SSB bursts with two SSBs having indexes 1,4 or 0,3, respectively, and the second 10ms receives a set of SSB bursts with four SSBs having indexes 1,2,3,4 or 0,1,2,3, respectively.

Option 3) the meaning of the first SSB index indication information is: dividing all bits L of the first SSB index indication information into K groups, wherein each group contains M bits of data, a first bit in a kth group in the K groups corresponds to a first SSB period in each second SSB period, and K SSBs are contained in corresponding SSB bursts at most; if the first SSB index indicates the nth position 1 in the information, it indicates that a group of SSB bursts in the first SSB period corresponding to the nth position include SSB with index value y. The value of y is an index value obtained by sequencing all bits in the first SSB index indication information. Or, the value of y is the group number corresponding to the nth bit after dividing the first SSB index indication information into K groups.

Specifically, taking the first SSB index indication information as SSB-locationinburst, the first SSB period as the repeater SSB period, and the second SSB period as the terminal SSB period as an example, if the maximum allowable SSB number L in the SSB burst is equal to K times of M, dividing all the bit numbers in the SSB-locationinburst into K groups, wherein each group comprises M bits, the first bit in the kth group in the SSB-locationinburst corresponds to the first repeater SSB period in each terminal SSB period, and the corresponding SSB burst contains at most K SSBs. The nth position 1 in SSB-locationinburst represents that SSB with index value y is included in SSB burst of the corresponding repeater. As one implementation, y refers to an index value obtained by sequencing all bits in ssb-PositionInBurst, and specifically takes the value of 1,2 … L or 0,1 … L-1. As another implementation manner, y refers to the group number corresponding to the nth position after ssb-positioning InBurst is divided into K groups, and specifically takes the value of 1,2 … K or 0,1 … K-1.

As an example: the SSB period of the repeater is denoted by N, the SSB period of the terminal is denoted by T, and the value of T can be referred to the current standard. The SSB period of the terminal is M times that of the SSB period of the repeater, i.e., T/n=m, and the maximum SSB number L allowed in the SSB burst is equal to K times that of M (i.e., K (T/N)). L=8, SSB-positioninburst=10, 01,11, t=20 ms, n=10 ms, k=4, and SSB-positioninburst is divided into two groups, and the repeater receives one SSB burst every 10ms, and receives one SSB burst every 20ms in the first 10ms, and includes three SSBs, and the index value is divided into 0,4,6 or 1,5,7, and receives one SSB burst in the second 10ms, and includes three SSBs, and the index value is 3,5,7 or 4,6,8, respectively.

As an example: the SSB period of the repeater is denoted by N, the SSB period of the terminal is denoted by T, and the value of T can be referred to the current standard. The SSB period of the terminal is M times that of the SSB period of the repeater, i.e., T/n=m, and the maximum SSB number L allowed in the SSB burst is equal to K times that of M (i.e., K (T/N)). L=8, SSB-positioninburst=10, 01,11, t=20 ms, n=10 ms, k=4, and SSB-positioninburst is divided into two groups, and the repeater receives one SSB burst every 10ms, and receives one SSB burst every 20ms in the first 10ms, and includes three SSBs, and the index value is divided into 0,2,3 or 1,3,4, and receives one SSB burst in the second 10ms, and includes three SSBs, and the index value is 1,2,3 or 2,3,4, respectively.

The unit of the SSB period may be a slot (slot), a millisecond (ms), or the like, which is not limited by the present application.

Configuration of search space

In the embodiment of the present application, the configuration information includes a configuration of the first search space. In some optional embodiments, the configuration information further includes a configuration of a second search space, where the second search space is a search space of the terminal.

Here, the first search space and the second search space do not overlap in a time domain; alternatively, the first search space and the second search space overlap in the time domain.

Here, the first search space includes, but is not limited to, a search space for Random Access (RA), a search space for SIB1, a search space for other system information (Other System Information, OSI), and the like. In order to ensure that the repeater-specific search space does not overlap in the time domain with the search space of the terminal, the configuration of the first search space comprises at least one of:

a first scale factor, the first scale factor being a scale factor of a period of the first search space relative to a period of the second search space;

a first offset, the first offset being an offset of the first search space over its period relative to an offset of the second search space over its period;

A first duration, the first duration referring to a duration of the first search space.

In some alternative embodiments, the period of the first search space is equal to the period of the second search space multiplied by the first scale factor. Here, the first ratio may be an integer or a fraction. The period of the first search space satisfies at least one of the following conditions:

the period of the first search space does not belong to the first set;

the period of the first search space is not equal to a common divisor of any candidate period in the first set;

the period of the first search space is not equal to a common multiple of any candidate period in the first set;

wherein the first set includes one or more candidate periods of the second search space. Here, as an example: the first set is the following set:

{1,2,4,5,8,10,16,20,40,80,160,320,640,1280,2560}*slot。

in some alternative embodiments, the offset of the first search space in its period is equal to the offset of the second search space in its period minus the first offset.

Here, if the first offset is less than 0, an absolute value of the first offset is equal to or greater than a duration of the first search space; and if the first offset is greater than 0, the first offset is greater than or equal to the duration of the first search space.

Here, if the offset of the second search space in its period is 0, the offset of the first search space in its period is equal to the period of the first search space minus the first offset.

Here, if the offset of the first search space in its period is calculated to be less than 0, the offset of the first search space in its period is considered to be 0.

As an example: as shown in fig. 5, the search space dedicated to the repeater (as a new search space) and the search space of the terminal (as an original search space) do not overlap in the time domain. In order to ensure that the search space dedicated to the repeater does not overlap with the search space of the terminal in the time domain, the configuration of at least one of the following needs to be added in comparison with the search space of the terminal:
