Description

Method and device for sending uplink control channel, server and terminal equipment

Technical Field

The embodiment of the application relates to the technical field of communication, in particular to a method and a device for sending an uplink control channel and terminal equipment.

Background

Before Radio Resource Control (RRC) connection is established, a base station cannot configure a Physical Uplink Control Channel (PUCCH) resource set for a User Equipment (UE) through a high-level RRC signaling, and therefore a mode of predefining a PUCCH resource set by a protocol is adopted. Meanwhile, before the RRC connection is established, the requirement of the UE on the PUCCH is only response information for feeding back signaling for establishing the RRC connection, so that the PUCCH resource in the predefined PUCCH resource set only needs to carry 1-2 bits of response information, namely the PUCCH resource in the predefined PUCCH resource set only consists of PUCCH format 0 and PUCCH format 1.

In the related art, multiple sets of such resource sets containing only PUCCH format 0 or PUCCH format 1 are predefined. Each of the predefined sets of PUCCH resources includes 16 PUCCH resources, and multiuser multiplexing is performed only by Physical Resource Block (PRB) and cyclic shift.

However, the transmission power of the base station or the terminal in the unlicensed spectrum is limited by the Power Spectral Density (PSD), for example: its PSD is 13dB/MHz in korea, which means that if the frequency domain width of the signal is 1MHz, the maximum transmission power of the UE is only 13 dBm. In the prior art, only PUCCH format 0 and PUCCH format 1 are supported to occupy one PRB in the frequency domain, and if PUCCH format 0 and PUCCH format 1 operate in 60GHz unlicensed spectrum, the maximum transmission power of UE is limited, and cannot reach the maximum transmission power of UE, which may affect the uplink coverage of UE.

Detailed Description

The terminology used in the description of the embodiments section of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the present application.

Before the RRC connection is established, the base station cannot configure a PUCCH resource set for the UE through a high-level RRC signaling, so a mode of predefining the PUCCH resource set by a protocol is adopted.

In the prior art, PUCCH resources in a predefined PUCCH resource set only need to carry 1-2 bits of response information, that is, PUCCH resources in the predefined PUCCH resource set only consist of PUCCH format 0 and PUCCH format 1.

In the related art, multiple sets of such resource sets containing only PUCCH format 0 or PUCCH format 1 are predefined. Each of the pre-defined sets of PUCCH resources contains 16 PUCCH resources and is multiuser multiplexed only by PRB and cyclic shift. Wherein the predefined table may be as shown in table 1.

TABLE 1

The prior art only supports that PUCCH format 0 and PUCCH format 1 occupy one physical resource block, so that if PUCCH format 0 and PUCCH format 1 operate in 60GHz unlicensed spectrum, the maximum transmission power of the UE is limited, and cannot reach the maximum transmission power, which may affect the uplink coverage of the UE. On the other hand, if the number of physical resource blocks occupied by the PUCCH format 0 and PUCCH format 1 is increased, the conventional PUCCH resource determination method has a problem.

Based on the above problem, embodiments of the present application provide a method for transmitting an uplink control channel, which can determine the number of physical resource blocks occupied by PUCCH resources before RRC connection establishment by a terminal device, so as to increase the number of physical resource blocks occupied by PUCCH format 0 and PUCCH format 1, improve transmission power of the terminal device, and expand an uplink coverage of the terminal device.

in 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 may determine the number of physical resource blocks occupied by each PUCCH resource, so that PUCCH format 0 and PUCCH format 1 may occupy multiple physical resource blocks, and thus when PUCCH format 0 and PUCCH format 1 operate in the 60GHz unlicensed spectrum, the terminal device may achieve the maximum transmission function, and the uplink coverage of the terminal device is increased.

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

In this embodiment, when determining the identifier of the physical resource block where the first hop and the second hop of the PUCCH are located, frequency hopping is performed using a plurality of physical resource blocks as a group, where the number of physical resource blocks in the group of physical resource blocks is the number of physical resource blocks occupied by each PUCCH resource.

And 203, transmitting the PUCCHs on the physical resource blocks of the number according to the identifier of the physical resource block of the first hop, the identifier of the physical resource block of the second hop and the initial cyclic shift identifier.

In this embodiment, the PUCCH format 0/PUCCH format 1 may spread the sequence thereof in the frequency domain, so that the sequence length is equal to the number of subcarriers included in the physical resource block, and then map the number of subcarriers to the physical resource block for transmission. The spreading may be a repetition of the same sequence, or may be a different cyclic shift of the same sequence, and form one or a group of sequences.

In this embodiment, the 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 information carried by the PUCCH is repeated a number of times equal to the number of physical resource blocks to which it is mapped. The information after multiple repetitions is multiplied by one or more sequences, where the sequences are different cyclic shifts of the same sequence. The number of sequences is equal to the number of physical resource blocks.

Specifically, in an implementation manner, in step 201 in the embodiment shown in fig. 2 of the present application, the terminal device determines that the number of physical resource blocks occupied by each PUCCH resource may be: a terminal device receives a system message or a high-level signaling sent by a base station, wherein the system message or the high-level signaling carries a parameter set of an initial uplink bandwidth part (BWP); then, the terminal device determines the number of physical resource blocks occupied by each PUCCH resource in the BWP according to the parameter set of the initial uplink BWP; wherein the number of physical resource blocks occupied by each PUCCH resource is inversely related to the parameter set of the initial uplink BWP.

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

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

Specifically, in the unlicensed frequency band around 60GHz, the power spectral density (power spectral density) of the terminal device is limited, for example: somewhere, the PSD of the terminal device is 13dB/MHz, which means that if the frequency domain width of the signal is 1MHz, the maximum transmit power of the terminal device is 13 dBm. Considering that the frequency domain size of one physical resource block is positively correlated with the subcarrier spacing size, the upper limit of the transmission 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 transmission power of the terminal device on a single physical resource block is 14.6dBm, if the subcarrier spacing is 240KHz, the maximum transmission power of the terminal device on a single physical resource block is 17.6dBm, if the subcarrier spacing is 480KHz, the maximum transmission power of the terminal device on a single physical resource block is 20.6dBm, and if the subcarrier spacing is 960KHz, the maximum transmission power of the terminal device on a single physical resource block is 23.6 dBm.

Therefore, in order to reach the maximum transmission power of 23dBm of the terminal, when the subcarrier spacing is 120KHz, 8 physical resource blocks are required for each PUCCH resource; when the subcarrier spacing is 240KHz, each PUCCH resource needs 4 physical resource blocks; when the subcarrier interval is 480KHz, each PUCCH resource needs 2 physical resource blocks; when the subcarrier spacing is 960KHz, 1 physical resource block is required per PUCCH resource.

In another implementation, the terminal device may determine the number of physical resource blocks occupied by each PUCCH resource as: the terminal equipment receives a system message or a high-level signaling sent by a base station, wherein the system message or the high-level signaling carries configuration parameters, and the configuration parameters indicate 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 configuration parameters.

That is to say, in this implementation, the base station configures, in a system message or a higher layer signaling, the number of physical resource blocks occupied by each PUCCH resource for each PUCCH resource, so that after receiving the configuration parameter, the terminal device may determine the number of physical resource blocks occupied by each PUCCH resource according to the configuration parameter.

For example, the implementation manner of the base station carrying the configuration parameters in the system message or the higher layer signaling may be as follows:

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

In another implementation, the terminal device may determine that the number of physical resource blocks occupied by each PUCCH resource may be: and determining the number of physical resource blocks occupied by each PUCCH resource according to the identification of the PUCCH resource used for transmitting the PUCCH.

Specifically, according to the identifier of the PUCCH resource used for transmitting the PUCCH, determining the number of physical resource blocks occupied by each PUCCH resource may be: determining a grouping to which the PUCCH resource used for transmitting the PUCCH belongs according to the identification of the PUCCH resource used for transmitting the PUCCH; determining the number of physical resource blocks occupied by each PUCCH resource according to the grouping to which the PUCCH resource belongs; the physical resource blocks occupied by the PUCCH resources belonging to the same grouping are the same in number, and the physical resource blocks occupied by the PUCCH resources belonging to different groupings are different in number.

That is, different PUCCH resources in one PUCCH resource set occupy different numbers of physical resource blocks, for example: the 16 PUCCH resources in table 1 may be divided into a plurality of groups, and the PUCCH resources belonging to the same group occupy the same number of physical resource blocks, and the PUCCH resources belonging to different groups occupy different numbers of physical resource blocks.

In specific implementation, if the terminal equipment needs to feed back hybrid automatic repeat request (hybrid automatic repeat request) in one PUCCH transmissionHARQ-Acknowledgement Character (ACK), the terminal device may determine the identifier γ of the PUCCH resource used for transmitting the PUCCH according to equation (1) _PUCCH ，0≤γ _PUCCH ≤15。

In the formula (1), N _CCE Is the number of Control Channel Elements (CCEs) in a control resource set (CORESET) in which a Physical Downlink Control Channel (PDCCH) carrying Downlink Control Information (DCI) is located, n _CCE,0 Is the first CCE where the PDCCH carrying the DCI is located, Δ _PRI Is a value of the PUCCH resource indication field in DCI.

Then, the terminal device may group the PUCCH resources according to the identifier of the PUCCH resource used for transmitting the PUCCH, and the following description will take the example of dividing the 16 PUCCH resources in table 1 into 4 groups.

In one embodiment, if

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

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

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

The terminal device determines that each PUCCH resource occupies 1 physical resource block.

Of course, the above is only one implementation manner, and the present embodiment is not limited to this, and the 16 PUCCH resources in table 1 may be divided into 2 groups, 3 groups, or 5 groups, and the present embodiment does not limit the number of groups into which the 16 PUCCH resources are divided, and the number of physical resource blocks occupied by each PUCCH resource in each group.

As described above, if the terminal device needs to feed back HARQ-ACK in one PUCCH transmission, the terminal device may determine the identity γ of the PUCCH resource used for transmission of PUCCH by equation (1) _PUCCH Thus, in step 202 of the embodiment shown in fig. 2 of the present application, determining, according to the identifier of the PUCCH resource and the number of physical resource blocks occupied by each PUCCH resource, the identifier of the physical resource block where the first hop for transmitting the PUCCH is located, the identifier of the physical resource block where the second hop for transmitting the PUCCH is located, and the initial cyclic shift identifier used for transmitting the PUCCH may be:

if it is not

The terminal equipment determines that the identification of the physical resource block where the first hop for transmitting the PUCCH is located is

The identification of the physical resource block where the second hop of the transmission PUCCH is

If it is not

Terminal equipment pass (gamma) _PUCCH -8)modN _CS To determine the initial cyclic shift identity used for transmission of the PUCCH.

For PUCCH resource identity 0, PUCCH resources are mapped in the time domain onto symbol 9.

Wherein N is _CS Is the number of initial cyclic shift identities contained in the initial set of cyclic shift identities, M _PRB Is the number of physical resource blocks occupied by each PUCCH resource,

is the number of physical resource blocks that the BWP contains,

is the starting physical resource block of BWP. Terminal equipment passes through gamma _PUCCH modN _CS To determine the initial cyclic shift identity used for transmission of the PUCCH.

According to the method for transmitting the uplink control channel provided by the embodiment of the application, the number of physical resource blocks occupied by the PUCCH format 0 and the PUCCH format 1 is increased, and the problems that the maximum transmission power of terminal equipment is limited and uplink coverage is insufficient are solved by the determination mode of the PUCCH resource under the condition that the number of physical resource blocks occupied by the PUCCH format 0 and the PUCCH format 1 is increased.
