Transmission method, device and terminal equipment for uplink control channel

This application claims the priority of the Chinese patent application filed on January 20, 2021 with the application number of 202110072696.9 and the invention titled "Method, Apparatus, Server and Terminal Equipment for Sending Uplink Control Channels", the entire contents of which are obtained through Reference is incorporated in this application.

technical field

Background technique

Before the radio resource control (RRC) connection is established, the base station cannot configure the physical uplink control channel (PUCCH) resource set for the user equipment (UE) through high-layer RRC signaling. How the protocol predefines the set of PUCCH resources. At the same time, before the RRC connection is established, the UE's requirement for PUCCH is only the response information used to feed back the signaling for establishing the RRC connection, so the PUCCH resources in the predefined PUCCH resource set only need to carry 1-2 bits of response information. That is, the PUCCH resources in the predefined PUCCH resource set are only composed of PUCCH format 0 and PUCCH format 1.

In the related art, multiple sets of such resource sets that only include PUCCH format 0 or PUCCH format 1 are predefined. Each of the predefined multiple PUCCH resource sets includes 16 PUCCH resources, and multi-user multiplexing is performed only through physical resource blocks (PRBs) and cyclic shifts.

However, on the unlicensed spectrum, the transmit power of the base station or terminal is limited by the power spectral density (PSD). For example, in Korea, the PSD is 13dB/MHz, which means that if the frequency domain width of the signal is 1MHz, Then the maximum transmit power of the UE is only 13dBm. Existing related technologies only support PUCCH format 0 and PUCCH format 1 occupying one PRB in the frequency domain. If PUCCH format 0 and PUCCH format 1 work on the 60GHz unlicensed spectrum, the maximum transmit power of the UE will be limited and cannot reach the UE's maximum transmit power. Maximum transmit power, which will affect the UE's uplink coverage.

Step 201, the terminal device determines the number of physical resource blocks occupied by each PUCCH resource, and determines the identifier of the PUCCH resource used for PUCCH transmission.

In this embodiment, the terminal device can determine the number of physical resource blocks occupied by each PUCCH resource, so that PUCCH format 0 and PUCCH format 1 can occupy multiple physical resource blocks. On the licensed spectrum, the terminal equipment can achieve the maximum transmission function, which increases the uplink coverage of the terminal equipment.

Step 202, according to the identifier of the PUCCH resource and the number of physical resource blocks occupied by each PUCCH resource, determine the identifier of the physical resource block where the first hop for transmitting PUCCH is located, and the identifier for the physical resource block where the second hop for transmitting PUCCH is located. and the initial cyclic shift identifier used to transmit the PUCCH.

In this embodiment, when determining the identifiers of the physical resource blocks where the first and second hops of the PUCCH transmission are located, frequency hopping is performed by taking multiple physical resource blocks as a group, and the physical resource blocks in this group of physical resource blocks are used for frequency hopping. The number of is the number of physical resource blocks occupied by each PUCCH resource.

Step 203: According to the identifier of the physical resource block where the first hop is located, the identifier of the physical resource block where the second hop is located, and the initial cyclic shift identifier, transmit the PUCCH on the above-mentioned number of physical resource blocks.

In this embodiment, PUCCH format 0/PUCCH format 1 extends its sequence in the frequency domain, so that the sequence length is equal to the number of subcarriers included in the above-mentioned physical resource block, and then maps to the number of physical resource blocks for transmission. The extended sequence can be a repetition of the same sequence, or different cyclic shifts of the same sequence can be used to form one or a group of sequences.

In this embodiment, PUCCH format 0/PUCCH format 1 is spread in the frequency domain, and then mapped to the number of physical resource blocks for transmission. The spreading may be that the information carried on the PUCCH is repeated multiple times, and the number of repetitions is equal to the number of physical resource blocks to which it is mapped. The repeated information is multiplied with one or more sequences, and the multiple sequences are different cyclic shifts of the same sequence. The number of its sequences is equal to the above-mentioned number of physical resource blocks.

In the above-mentioned method for sending an uplink control channel, the terminal device determines the number of physical resource blocks occupied by each PUCCH resource, and determines the identifier of the PUCCH resource used for transmitting the PUCCH, and then determines the identifier of the PUCCH resource according to the identifier and the number of physical resource blocks occupied by each PUCCH resource. The number of physical resource blocks, determine the identity of the physical resource block where the first hop of the transmission PUCCH is located, the identity of the physical resource block where the second hop of the transmission PUCCH is located, and the initial cyclic shift identity used for the transmission of the PUCCH. The identifier of the physical resource block where one hop is located, the identifier of the physical resource block where the second hop is located, and the initial cyclic shift identifier, transmit the PUCCH on the above-mentioned number of physical resource blocks, so that the terminal device can be implemented before the RRC connection is established. Determine the number of physical resource blocks occupied by PUCCH resources, increase the number of physical resource blocks occupied by PUCCH format 0 and PUCCH format 1, improve the transmission power of the terminal equipment, and expand the uplink coverage of the terminal equipment.

Specifically, in an implementation manner, in step 201 of the embodiment shown in FIG. 2 of the present application, the terminal device determines the number of physical resource blocks occupied by each PUCCH resource, which may be: the terminal device receives a system message or high-level information sent by the base station Let, the parameter set of the initial uplink bandwidth part (bandwidth part, BWP) is carried in the above-mentioned system message or high-level signaling; then, the terminal device determines the physical resource block occupied by each PUCCH resource in the above-mentioned BWP according to the parameter set of the initial uplink BWP , wherein the number of physical resource blocks occupied by each PUCCH resource is negatively correlated with the parameter set of the initial uplink BWP.

In this implementation manner, the parameter set of the initial uplink BWP may include subcarrier spacing; or, the parameter set of the initial uplink BWP may include subcarrier spacing and cyclic prefix type.

For example, if the subcarrier spacing is 120KHz, each PUCCH resource occupies 8 physical resource blocks, if the subcarrier spacing is 240KHz, each PUCCH resource occupies 4 physical resource blocks, if the subcarrier spacing is 480KHz, then Each PUCCH resource occupies 2 physical resource blocks, and if the subcarrier spacing is 960KHz, each PUCCH resource occupies 1 physical resource block.

Specifically, in the unlicensed frequency band around 60GHz, the power spectral density of the terminal equipment is limited, for example: in a certain place, the PSD of the terminal equipment is 13dB/MHz, which means that if the frequency domain width of the signal is If it is 1MHz, the maximum transmit power of the terminal device is 13dBm. Considering that the frequency domain size of a physical resource block is positively correlated with the subcarrier spacing, the upper limit of the transmit power of the terminal device is also positively correlated with the frequency domain size of the physical resource block, as shown in Table 2.

Table 2

Referring to Table 2, if the subcarrier spacing is 120KHz, the maximum transmit power of the terminal equipment on a single physical resource block is 14.6dBm, and if the subcarrier spacing is 240KHz, the maximum transmit power of the terminal equipment on a single physical resource block is 17.6 dBm dBm, if the subcarrier spacing is 480KHz, the maximum transmit power of the terminal device on a single physical resource block is 20.6dBm; if the subcarrier spacing is 960KHz, the maximum transmit power of the terminal device on a single physical resource block is 23.6dBm.

Therefore, in order to achieve the maximum transmit power of the terminal of 23dBm, when the subcarrier spacing is 120KHz, each PUCCH resource requires 8 physical resource blocks; when the subcarrier spacing is 240KHz, each PUCCH resource requires 4 physical resource blocks; when When the subcarrier spacing is 480KHz, each PUCCH resource requires 2 physical resource blocks; when the subcarrier spacing is 960KHz, each PUCCH resource requires 1 physical resource block.

In another implementation manner, the terminal device may determine the number of physical resource blocks occupied by each PUCCH resource as follows: the terminal device receives a system message or high-level signaling sent by the base station, and the system message or high-level signaling carries configuration parameters, and the above-mentioned system message or high-level signaling carries configuration parameters. The configuration parameter indicates the number of physical resource blocks occupied by each PUCCH resource; then, the terminal device determines the number of physical resource blocks occupied by each PUCCH resource according to the above configuration parameter.

That is to say, in this implementation manner, the base station configures the number of physical resource blocks occupied by the PUCCH resource for each PUCCH resource in a system message or high-level signaling. In this way, after receiving the above configuration parameters, the terminal device can The configuration parameter determines the number of physical resource blocks occupied by each PUCCH resource.

For example, the implementation of the base station carrying configuration parameters in system messages or high-layer signaling may be as follows:

The above "PRB number" is the number of physical resource blocks occupied by the PUCCH resource configured by the base station for each PUCCH resource.

In yet another implementation manner, the terminal device determining the number of physical resource blocks occupied by each PUCCH resource may be: determining the number of physical resource blocks occupied by each PUCCH resource according to the identifier of the PUCCH resource used for PUCCH transmission.

Specifically, determining the number of physical resource blocks occupied by each PUCCH resource according to the identifier of the PUCCH resource used for PUCCH transmission may be: according to the identifier of the PUCCH resource used for PUCCH transmission, determining the PUCCH resource used for PUCCH transmission belongs to Grouping; determine the number of physical resource blocks occupied by each PUCCH resource according to the grouping to which the above-mentioned PUCCH resources belong; wherein the number of physical resource blocks occupied by PUCCH resources belonging to the same group is the same, and the physical resources occupied by PUCCH resources belonging to different groups The number of blocks varies.

That is to say, different PUCCH resources in a PUCCH resource set occupy different numbers of physical resource blocks. For example, the 16 PUCCH resources in Table 1 can be divided into multiple groups, and the number of physical resource blocks occupied by PUCCH resources belonging to the same group is If the number is the same, the number of physical resource blocks occupied by PUCCH resources belonging to different groups is inconsistent.

During specific implementation, if the terminal device needs to feed back a hybrid automatic repeat request (HARQ)-acknowledge character (ACK) in a PUCCH transmission, the terminal device can determine the transmission PUCCH through formula (1). The identifier of the used PUCCH resource γ _PUCCH , 0≤γ _PUCCH ≤15.

In formula (1), N _CCE is the control channel element ( The number of control channel elements, CCEs), n _{CCE, 0} is the first CCE where the PDCCH carrying the DCI is located, and _ΔPRI is the value of the PUCCH resource indication field in the DCI.

Then, the terminal device may group the PUCCH resources according to the identifiers of the PUCCH resources used to transmit the PUCCH. The following description will be given by dividing the 16 PUCCH resources in Table 1 into 4 groups as an example.

则终端设备确定每个PUCCH资源占据8个物理资源块，如果

则终端设备确定每个PUCCH资源占据4个物理资源块，如果

则终端设备确定每个PUCCH资源占据2个物理资源块，如果

则终端设备确定每个PUCCH资源占据1个物理资源块。 In one embodiment, if

Then the terminal device determines that each PUCCH resource occupies 8 physical resource blocks, if

Then the terminal device determines that each PUCCH resource occupies 4 physical resource blocks, if

Then the terminal device determines that each PUCCH resource occupies 2 physical resource blocks, if

Then the terminal device determines that each PUCCH resource occupies one physical resource block.

Of course, the above is only an implementation manner, and this embodiment is not limited to this. The 16 PUCCH resources in Table 1 may also be divided into 2 groups, 3 groups, or 5 groups. In this embodiment, the 16 PUCCH resources The number of divided groups and the number of physical resource blocks occupied by each PUCCH resource in each group are not limited.

As mentioned above, if the terminal device needs to feed back HARQ-ACK in one PUCCH transmission, the terminal device can determine the identifier γ _PUCCH of the PUCCH resource used to transmit the PUCCH through equation (1). In this way, the embodiment shown in FIG. 2 of the present application In step 202, according to the identifier of the PUCCH resource and the number of physical resource blocks occupied by each PUCCH resource, determine the identifier of the physical resource block where the first hop for transmitting PUCCH is located, and the identifier for the physical resource block where the second hop for transmitting PUCCH is located. The initial cyclic shift identification used to identify and transmit the PUCCH may be:

if

Then the terminal equipment determines that the identifier of the physical resource block where the first hop of the transmission PUCCH is located is:
