The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.

In the related art, for the transmission of the feedback message of the message 4 (msg 4) in the random access process, the second hop exceeds the system bandwidth of the redcap UE, and the unreserved symbols in the resources configured for the redcap UE to transmit the PUCCH are currently used for radio frequency retuning.

To solve the problem, the embodiment of the application provides a radio frequency retuning method and a radio frequency retuning device.

Fig. 1 is a schematic diagram of a radio frequency retuning method according to the present application. It should be noted that the radio frequency retuning method of the present application may be executed by a capability-limited terminal RedcapUE.

As shown in fig. 1, the radio frequency retuning method provided by the present application includes the following steps:

s101, determining a target symbol for RF retuning, wherein the target symbol is located before a symbol for transmitting information in a second hop of a Physical Uplink Control Channel (PUCCH) transmitted by a redcap UE.

In this application, the target symbol may be, for example, at least one symbol that is consecutive at the end of the first hop and/or at least one symbol that is consecutive at the beginning of the second hop. The target symbol may be, for example, a gap symbol between a first hop for transmitting PUCCH and a second hop for transmitting PUCCH, where a starting symbol of the second hop is determined based on the second PUCCH resource configuration, and a value of the starting symbol is greater than a value of a starting symbol of the second hop determined according to the first PUCCH resource configuration; or, a gap symbol between a first hop for transmitting the PUCCH and a second hop for transmitting the PUCCH, wherein a starting symbol of the first hop is determined based on the second PUCCH resource configuration, and a value of the starting symbol is smaller than a value of a starting symbol of the first hop determined according to the first PUCCH resource configuration. The first hop and the second hop are different time-frequency resources used for transmitting the PUCCH.

In the present application, the first PUCCH resource configuration refers to the PUCCH resource configuration in table 1 below. The second PUCCH resource configuration refers to a PUCCH resource configuration in each table other than table 1. Wherein each table other than table 1, for example, table 2, table 3, or table 4 mentioned in the subsequent examples, and the like.

In the present application, the resource used for sending the PUCCH is a resource configured by the network device for RedcapUE through the resource indication information. The resource indication information may include, for example, an index number, and the RedcapUE queries the first PUCCH resource Table according to the index number, that is, table 9.2.1-1: the PUCCH resource sets are configured to be determined PUCCH resource configuration, that is, the resource configured for the RedcapUE to transmit the PUCCH may be queried. For example, the resource indication information may be SIB1 for PUCCH for msg4 feedback, and the information in PUCCH for msg4 feedback may be, for example, ACK information for msg 4.

Table 9.2.1-1 in this application can be as shown in Table 1 below.

TABLE 1 Table 9.2.1-1

It can be understood that each element and each corresponding relationship in table 1 are independent; these elements, correspondences, are exemplarily listed in the same table, but do not represent that all elements, correspondences, in the table must coexist according to the representation in table 1. Wherein the value of each element and each correspondence is independent of any other element value or correspondence in table 1. Therefore, as can be understood by those skilled in the art, the value of each element and each corresponding relationship in table 1 are all independent embodiments. In table 1, an entry or a combination of entries indicated by an index may be regarded as one PUCCH resource configuration. Those skilled in the art can flexibly configure the solution based on the needs and purposes of the technical solution. Table 1 is a table for PUCCH resource configuration specified in a communication standard promulgated by the 3GPP organization at the time of filing this disclosure. Tables 2-4 are example PUCCH resource configuration tables provided by the present disclosure.

In table 1, index denotes an Index number; the PUCCH format represents a resource format; first symbol represents the starting symbol of the First hop; number of symbols field, which represents the sum of the Number of symbols of the first hop and the Number of symbols of the second hop. In table 1, the symbols of the first hop and the symbols of the second hop are consecutive symbols, that is, there is no interval symbol between the symbols of the first hop and the symbols of the second hop. The RedcapUE can obtain the initial symbol of the first hop and the sum of the number of the symbols of the first hop and the number of the symbols of the second hop according to the index number lookup table 1, and further determine the symbols of the first hop and the symbols of the second hop.

As a possible implementation, the number of target symbols may be determined by at least one of the following ways: the method comprises the steps of determining according to the subcarrier interval of PUCCH resources on a frequency domain, determining according to the type of a terminal Redcap UE with limited capability for executing radio frequency readjustment processing, stipulating a protocol and indicating by network equipment.

S102, performing Radio Frequency (RF) resetting on the target symbol.

In this application, as an example, redcapUE shares the same initial uplink bandwidth part initial UL BWP with non-RedcapUE, that is, normal User Equipment (normal UE), in order to avoid the effect of redcap UE on normal UE, a larger initial UL BWP may be configured according to the capability of normal UE, and the BWP may be larger or much larger than the system bandwidth of redcap UE.

As another example, redcapUE and non-RedcapUE configure the initial uplink bandwidth part initial UL BWP independently. However, to increase the frequency selective gain and frequency diversity gain of redcap UE, redcap UE may be configured with a larger initial UL BWP, which may be larger or much larger than the system bandwidth of redcap UE.

In both examples above, for the transmission of the feedback message of message 4 (msg 4) in the random access procedure, the second hop exceeds the system bandwidth of the redcap UE, so the target symbol is needed for the rf retuning of the redcap UE before the symbol for transmitting information in the second hop, and the redcap UE does not transmit information on the target symbol.

For example, before the symbol used by the RedcapUE for transmitting information in the second hop, if the frequency of the second hop is outside the system bandwidth of the redcap UE, the RedcapUE may perform radio frequency retuning on the target symbol, so that the RedcapUE can transmit information at the frequency of the second hop; if the frequency of the second hop is within the system bandwidth of the redcap UE, the redcap UE may transmit information directly on the symbols used to transmit information in the second hop.

As a possible implementation manner, in order to improve the utilization rate of resources, target symbols, for example, the target symbols, may be multiplexed for transmitting information of non-Redcap UEs, where the symbols for transmitting the information of the non-Redcap UEs are part of or all of the target symbols.

As a possible implementation, the resource for transmitting PUCCH of the Redcap UE is configured independently from the resource for transmitting PUCCH of the non-Redcap UE. As an example, two index numbers may be set in SIB1, and respectively correspond to a Redcap UE and a non-Redcap UE, so that the Redcap UE may obtain a resource for transmitting a PUCCH according to the corresponding index numbers; the non-Redcap UE can obtain the resource for transmitting the PUCCH according to the corresponding index number.

As another example, an index number may be set in SIB1, and the Redcap UE queries a corresponding first PUCCH resource table according to the index number to obtain a resource for transmitting a PUCCH; the non-Redcap UE can query the corresponding first PUCCH resource table according to the index number to obtain the resources for sending the PUCCH. That is, the Redcap UE and the non-Redcap UE correspond to different first PUCCH resource tables.

According to the radio frequency retuning method of the embodiment of the application, the target symbol for radio frequency retuning RF retuning can be determined, wherein the target symbol is located before the symbol for transmitting information in the second hop of the physical uplink control channel PUCCH sent by the redcap UE, so that the radio frequency retuning RF retuning can be performed on the target symbol, and information can be transmitted on the symbol for transmitting information in the second hop after the radio frequency retuning process, and the information transmission efficiency can be improved.

As a possible implementation manner, as shown in fig. 2, the radio frequency retuning method provided by the present application includes the following steps:

s201, determining a first hop and a second hop for transmitting PUCCH based on a first PUCCH resource table.

In this application, the resource used for sending the PUCCH is a resource configured by the network device for RedcapUE through the resource indication information. The resource indication information may include, for example, an index number, and the RedcapUE queries the first PUCCH resource Table according to the index number, that is, table 9.2.1-1: the PUCCH resource sets are configured to be determined PUCCH resource configuration, that is, the resource configured for the RedcapUE to transmit the PUCCH may be queried. For PUCCH for msg4 feedback, the resource indication information may be SIB1, for example. In this application, the first hop and the second hop are different time-frequency resources for transmitting the PUCCH. The information in the PUCCH for msg4 feedback may be, for example, ACK information for msg 4.

S202, selecting at least one continuous symbol at the tail part of the first hop and/or at least one continuous symbol at the start part of the second hop as a target symbol.

In the present application, for the resource with format 1 in table 1, in consideration of the configuration that the demodulation reference signals DMRS exist at even symbol positions, in order to reduce the influence on the demodulation reference signals DMRS, the number of symbols in which demodulation reference signals are not configured, that is, the number of symbols in which demodulation reference signals are configured, in the target symbol, may be selected first, and is less than or equal to the number of symbols in which demodulation reference signals are not configured.

As shown in fig. 3, the resource with format 1 and starting symbol #4 of the first hop is illustrated. In fig. 3, symbols of the first hop are #4 to #8, symbols of the second hop are #9 to #13, and when the radio frequency retuning needs to occupy two symbols, #8 in the symbols of the first hop and #9 in the symbols of the second hop can be selected as target symbols; when the radio frequency retuning only needs to occupy one symbol, #9 in the symbols of the second hop can be selected as the target symbol.

In this application, at least one continuous symbol at the tail of the first hop and/or at least one continuous symbol at the start of the second hop are selected, and in the case of a target symbol, the symbol for transmitting information in the first hop does not coincide with the symbol of the configured first hop, and/or the symbol for transmitting information in the second hop does not coincide with the symbol of the configured second hop. For example, in fig. 3, when #8 of the symbols of the first hop and #9 of the symbols of the second hop are selected as target symbols, the symbols for transmitting information in the first hop are #4 to #7, and the symbols for transmitting information in the second hop are #10 to #13.

In the present application, the number of target symbols may be determined by at least one of the following ways: the method comprises the steps of determining according to the subcarrier interval of PUCCH resources on a frequency domain, determining according to the type of a terminal Redcap UE with limited capability for executing radio frequency readjustment processing, stipulating a protocol and indicating by network equipment.

S203, performing RF resetting on the target symbol.

In the present application, before the RedcapUE transmits the symbol of the information in the second hop, if the frequency of the second hop is outside the system bandwidth of the redcap UE, the RedcapUE may perform radio frequency retuning on the target symbol, so that the RedcapUE can transmit the information at the frequency of the second hop; if the frequency of the second hop is within the system bandwidth of the redcap UE, the redcap UE may transmit information directly on the symbols used to transmit information in the second hop.

As a possible implementation, the resource for transmitting PUCCH of the Redcap UE is configured independently from the resource for transmitting PUCCH of the non-Redcap UE.

Fig. 17 is a schematic diagram of a radio frequency retuning method according to the present application. It should be noted that the radio frequency retuning method of the present application may be executed by a network device corresponding to a capability-limited terminal RedcapUE.

As shown in fig. 17, the radio frequency retuning method provided by the present application includes the following steps:

s1701, sending resource indication information to a capability-limited terminal Redcap UE, wherein the resource indication information indicates that the Redcap UE determines a target symbol for RF resetting, and the target symbol is located before a symbol for transmitting information in a second hop of a physical uplink control channel PUCCH sent by the Redcap UE.

In this application, the resource used for sending the PUCCH is a resource configured by the network device for RedcapUE through the resource indication information. The resource indication information may include, for example, an index number, and the RedcapUE queries the first PUCCH resource Table according to the index number, that is, table 9.2.1-1: the PUCCH resource sets before determined PUCCH resource configuration may query the resource configured for the recappapse, and then determine the target symbol according to the resource configured for the recappapse. For PUCCH for msg4 feedback, the resource indication information may be SIB1, for example. The first hop and the second hop are different time-frequency resources for transmitting the PUCCH. The information in the PUCCH for msg4 feedback may be, for example, ACK information for msg 4.

In this application, the target symbol may be, for example, at least one symbol that is consecutive at the end of the first hop and/or at least one symbol that is consecutive at the beginning of the second hop. The target symbol may be, for example, a gap symbol between a first hop for transmitting PUCCH and a second hop for transmitting PUCCH, where a starting symbol of the second hop is determined based on the second PUCCH resource configuration, and a value of the starting symbol is greater than a value of a starting symbol of the second hop determined according to the first PUCCH resource configuration; a gap symbol between a first hop for transmitting the PUCCH and a second hop for transmitting the PUCCH, wherein a starting symbol of the first hop is determined based on the second PUCCH resource configuration and has a value smaller than that of the starting symbol of the first hop determined according to the first PUCCH resource configuration. The first PUCCH resource configuration may be a PUCCH resource configuration in a table for PUCCH resource configuration specified in a communication standard released by the 3GPP organization at the time of original text submission of the present disclosure.

As another possible implementation manner, after the network device issues the resource indication information to the capability-limited terminal RedcapUE, a target symbol may be determined; stopping receiving information transmitted by the Redcap UE on the target symbol, or discarding information of the Redcap UE received on the target symbol.

In this application, the manner in which the network device stops receiving the information transmitted by the Redcap UE may be to close a radio frequency component that receives the information on the target symbol. The method can be applied to the situation that two hops span the time slot and the interval between the two hops has more symbols.

In this application, the network device may discard the information of the Redcap UE received on the target symbol, such that the information decoding process is not performed on the information of the Redcap UE received on the target symbol. The method can be applied to the condition that two hops have the same time slot and the interval symbols between the two hops are less.

In one example, the target symbol may be, for example, a gap symbol between a first hop for transmitting PUCCH and a second hop for transmitting PUCCH, where a start symbol of the second hop is determined based on the second PUCCH resource configuration and has a value greater than that of the start symbol of the second hop determined according to the first PUCCH resource configuration. In this example, the network device may also issue specific information to RedcapUE, where the specific information includes: the number of target symbols or the second hop, for instructing the RedcapUE to determine the target symbols according to the designation information.

In another example, the target symbol may be, for example, a gap symbol between a first hop for transmitting PUCCH and a second hop for transmitting PUCCH, where a starting symbol of the first hop is determined based on the second PUCCH resource configuration and has a value smaller than that of the starting symbol of the first hop determined according to the first PUCCH resource configuration. In this example, the network device may also issue specific information to RedcapUE, where the specific information includes: the number of target symbols or the starting symbol of the first hop, which is used for instructing the RedcapUE to determine the target symbols according to the specified information.

As another possible implementation, a non-Redcap UE may be instructed to transmit information on some or all of the target symbols; or configuring resources for transmitting the PUCCH for the non-Redcap UE, wherein the resources for transmitting the PUCCH for the non-Redcap UE are independent of the resources for transmitting the PUCCH for the Redcap UE.

In another example, the target symbol is a symbol selected from an interval symbol, and the interval symbol is an interval symbol between a first hop in the first slot and a second hop in the second slot. Wherein, the target symbol is an unavailable symbol in the interval symbols; alternatively, the number of symbols in the target symbol that are not available is greater than or equal to the number of symbols in the available symbols.

In this example, to improve the utilization of the resource, the resource may be multiplexed, that is, a symbol except for the first hop on the first slot and a symbol except for the second hop on the second slot are configured for the second Redcap UE, so as to instruct the second Redcap UE to transmit information on the configured symbols.

According to the radio frequency retuning method provided by the embodiment of the application, the resource indication information can be issued to the capability-limited terminal Redcap UE, wherein the resource indication information indicates the Redcap UE to determine a target symbol for radio frequency retuning RF retuning, and the target symbol is located before a symbol for transmitting information in a second hop of a physical uplink control channel PUCCH (physical uplink control channel) sent by the redcap UE, so that the Redcap UE can transmit the information on the symbol of the second hop after the radio frequency retuning, and the information transmission efficiency is improved.
