The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to be used to explain the present application, but should not be construed as a limitation to the present application.

In the related art, for the transmission of the feedback message of message 4 (msg4) in the random access process, the situation that the second hop exceeds the system bandwidth of the redcap UE may occur, and the resources currently configured for the redcap UE for sending PUCCH are not predetermined. The notation is reserved for RF retuning.

To address this problem, embodiments of the present application provide a radio frequency retuning method and apparatus.

FIG. 1 is a schematic diagram of a radio frequency re-tuning method according to the present application. Among them, it should be noted that the radio frequency re-tuning method of the present application may be executed by the capability-limited terminal RedcapUE.

As shown in FIG. 1 , the radio frequency retuning method proposed in this application includes the following steps:

S101. Determine a target symbol for RF retuning, where the target symbol is located before the symbol used for transmitting information in the second hop of the physical uplink control channel PUCCH sent by the redcap UE.

In this application, the target symbol may be, for example, at least one consecutive symbol at the tail of the first hop, and/or at least one consecutive symbol at the beginning of the second hop. For another example, the target symbol may be an interval symbol between the first hop used for sending PUCCH and the second hop used for sending PUCCH, where the start symbol of the second hop is determined based on the second PUCCH resource configuration, The value of the start symbol is greater than the value of the start symbol of the second hop determined according to the first PUCCH resource configuration; or, the interval symbol between the first hop used for sending PUCCH and the second hop used for sending PUCCH , where the start symbol of the first hop is determined based on the second PUCCH resource configuration, and the value of the start symbol is smaller than the value of the start symbol of the first hop determined according to the first PUCCH resource configuration. Wherein, the first hop and the second hop are different time-frequency resources for sending PUCCH.

In this application, the first PUCCH resource configuration refers to the PUCCH resource configuration in Table 1 below. The second PUCCH resource configuration refers to the PUCCH resource configuration in each table except Table 1. Among them, each table other than Table 1, for example, Table 2, Table 3, or Table 4 mentioned in the subsequent embodiments.

In this application, the resource used for sending the PUCCH is the resource configured by the network device for the Redcap UE through the resource indication information. The resource indication information may include, for example, an index number. RedcapUE queries the first PUCCH resource table according to the index number, that is, Table 9.2.1-1: PUCCH resource sets before dedicated PUCCH resource configuration. Resource for sending PUCCH. Wherein, for the PUCCH for msg4 feedback, the resource indication information may be, for example, SIB1, and the information in the PUCCH for msg4 feedback may be, for example, the ACK information for msg4.

In this application, Table 9.2.1-1 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 exist independently; these elements and corresponding relationships are exemplarily listed in the same table, but do not represent all the elements in the table, Correspondence must exist according to the coexistence shown in Table 1. The value of each element and each corresponding relationship are independent of any other element value or corresponding relationship in Table 1. Therefore, those skilled in the art can understand that the value of each element and each corresponding relationship in Table 1 are each an independent embodiment. In Table 1, one entry or a combination of multiple entries indicated by an index can be regarded as one PUCCH resource configuration. Those skilled in the art can configure flexibly based on the needs and purposes of the technical solutions. Table 1 is a table for PUCCH resource configuration specified in the communication standards issued by the 3GPP organization when the present disclosure is submitted. Tables 2-4 are PUCCH resource configuration tables of improved examples provided by the present disclosure.

In this application, in Table 1, Index represents the index number; PUCCH format represents the resource format; First symbol represents the start symbol of the first hop; Number of symbols is the number of symbols field, representing the number of symbols of the first hop and the number of the second hop The sum of the number of symbols. In Table 1, the symbols of the first hop and the symbols of the second hop are continuous symbols, that is, there is no space symbol between the symbols of the first hop and the symbols of the second hop. Among them, RedcapUE queries Table 1 according to the index number, that is, it can obtain the start symbol of the first hop, and the sum of the number of symbols of the first hop and the number of symbols of the second hop, and then determine the symbol of the first hop and the number of the second hop. symbol.

As a possible implementation manner, the number of target symbols may be determined by at least one of the following manners: determined according to the subcarrier spacing of PUCCH resources in the frequency domain, according to Type determination, protocol specification, network device indication.

S102. Perform RF retuning on the target symbol.

In this application, as an example, Redcap UE and non-Redcap UE, namely normal user equipment (normal User Equipment, normal UE) share the same initial uplink bandwidth part initial UL BWP, in order to avoid the impact of redcap UE on normal UE, it may be based on The capability of normal UE configures a larger initial UL BWP, which may be larger or much larger than the system bandwidth of redcap UE.

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

In the above two examples, for the transmission of the feedback message of message 4 (msg4) in the random access process, the second hop will exceed the system bandwidth of the redcap UE. Therefore, the symbol used to transmit information in the second hop Previously, target symbols were required for RF retuning by RedcapUE, on which RedcapUE did not transmit information.

For example, before the symbol used to transmit information in the second hop, if the frequency of the second hop is outside the system bandwidth of the redcap UE, the Redcap UE can perform radio frequency re-tuning on the target symbol, so that the Redcap UE can use the second hop to perform radio frequency re-tuning. If the frequency of the second hop is within the system bandwidth of the redcap UE, the Redcap UE can directly transmit the information on the symbol used to transmit the information in the second hop.

As a possible implementation manner, in order to improve resource utilization, target symbols may be multiplexed, for example, target symbols are used to transmit information of non-Redcap UEs, wherein the symbols for transmitting information of non-Redcap UEs are target symbols some or all of the symbols in .

As a possible implementation manner, the resources used for sending the PUCCH of the Redcap UE and the resources used for sending the PUCCH of the non-Redcap UE are separately configured. As an example, two index numbers may be set in SIB1, corresponding to Redcap UEs and non-Redcap UEs respectively, so that Redcap UEs can obtain resources for sending PUCCH according to the corresponding index numbers; The index number is used to obtain the resource for sending the PUCCH.

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

According to the radio frequency retuning method according to the embodiment of the present application, the target symbol used for radio frequency retuning RF retuning can be determined, wherein the target symbol is located in the second hop of the physical uplink control channel PUCCH sent by the redcap UE. The symbol used for transmitting information Previously, RF retuning can be performed on the target symbol, so as to transmit information on the symbol used for transmitting information in the second hop after the radio frequency retuning process, and improve the information transmission efficiency.

As a possible implementation manner, as shown in FIG. 2 , the radio frequency retuning method proposed in this application includes the following steps:

S201. Based on the first PUCCH resource table, determine the first hop and the second hop for sending the PUCCH.

In this application, the resource used for sending the PUCCH is the resource configured by the network device for the Redcap UE through the resource indication information. The resource indication information may include, for example, an index number. RedcapUE queries the first PUCCH resource table according to the index number, that is, Table 9.2.1-1: PUCCH resource sets before dedicated PUCCH resource configuration. Resource for sending PUCCH. Wherein, for PUCCH for msg4 feedback, the resource indication information may be, for example, SIB1. In this application, the first hop and the second hop are different time-frequency resources for sending PUCCH. Wherein, the information in the PUCCH for msg4 feedback may be, for example, the ACK information for msg4.

S202. Select at least one consecutive symbol at the end of the first hop, and/or at least one consecutive symbol at the beginning of the second hop, as the target symbol.

In this application, for the resources with the format 1 in Table 1, considering that there is a configuration of the demodulation reference signal DMRS at the even-numbered symbol position, in order to reduce the impact on the demodulation reference signal DMRS, you can first select the demodulation reference signal that is not configured. , that is, in the target symbol, the number of symbols configured with demodulation reference signals is less than or equal to the number of symbols not configured with demodulation reference signals.

As shown in FIG. 3 , it is a schematic diagram of a resource whose format is 1 and the start symbol of the first hop is #4. In Fig. 3, the symbols of the first hop are #4 to #8, and the symbols of the second hop are #9 to #13. When the RF retuning needs to occupy two symbols, the # in the symbols of the first hop can be selected. 8 and #9 in the symbols of the second hop are used as target symbols; when only one symbol needs to be occupied by radio frequency retuning, #9 in the symbols of the second hop can be selected as the target symbol.

In this application, at least one consecutive symbol at the end of the first hop and/or at least one consecutive symbol at the beginning of the second hop is selected as the target symbol, and the first hop is used to transmit information The symbol of , is inconsistent with the configured symbol of the first hop, and/or, the symbol used for transmitting information in the second hop is inconsistent with the configured symbol of the second hop.
