Description

Uplink data transmission method, terminal and readable storage medium
Technical Field
The present invention relates to the field of communications technologies, and in particular, to an uplink data transmission method, a terminal, and a readable storage medium.
Background
In a Long Term Evolution (LTE) network, a Physical Uplink Control CHannel (PUCCH) is generally transmitted on both sides of a system bandwidth. To reduce the resources required for transmission, the LTE network exploits frequency diversity in PUCCH transmission, i.e. in the previous slot of the same subframe, PUCCH is transmitted on one physical Resource Block (RB) at or near the edge of the system bandwidth, while in the next slot of the subframe, PUCCH is transmitted on one Resource Block (RB) at or near the other edge of the system bandwidth.
Unlike 4G systems, fifth generation mobile communication (5G) systems are wide in bandwidth (400 MHz maximum). And because the 5G system needs to meet the transmission requirements of various users in different scenes, the bandwidths of the terminals in the system may be different. For this reason, in 5G, a concept of a partial BandWidth (BWP) is introduced, and for a terminal whose radio frequency BandWidth is smaller than the system BandWidth, a BWP smaller than or equal to the radio frequency BandWidth can be configured for the terminal, so that the terminal can perform frequency hopping transmission within the BWP, that is, carry and communicate information using carriers of different frequencies within a frequency range allowed by a communication channel.
In the 5G New Radio (NR) Release 16 Release and the previous standard technical research, the frequency hopping times of the PUCCH in one slot is only 2 times at most, that is, the PUCCH is divided into two parts in a frequency domain corresponding to one slot, and the two parts are respectively transmitted in two frequency domain positions.
However, PUCCH hops up to 2 times in a slot, limiting network coverage.

Detailed Description
Currently, in 5G, a terminal may hop within an active BWP, i.e. may carry and communicate information on carriers of different frequencies within the frequency range allowed by the communication channel. Specifically, the terminal firstly performs data transmission on a carrier wave in a set frequency band, and after a set duration, jumps to another set frequency band to continue data transmission.
However, in the existing protocol, the frequency hopping times of the PUCCH in one slot is only 2 times at most, which limits the network coverage.
To this end, an embodiment of the present invention provides an uplink data transmission method, in which a total frequency hopping number indicated in PUCCH resource configuration information is greater than or equal to 2 times, so that PUCCH resources in one slot are distributed in multiple frequency domain positions in a currently active BWP, and a terminal may transmit data in the multiple frequency domain positions in the currently active BWP, thereby enhancing network coverage.

In another embodiment of the present invention, the PUCCH Resource configuration information may be carried in a dedicated signaling, that is, the base station may send the PUCCH Resource configuration information to the terminal through the dedicated signaling, where the dedicated signaling may be a Radio Resource Control (RRC) signaling or other high-level signaling.

The number of the preset bits is specifically set according to the frequency hopping requirement. For example, the value of three bits in the PUCCH resource configuration information is "100", which indicates that the total number of hopping frequencies is 4. Of course, the total frequency hopping times may also be 3, 5, 6, 7, 8, 9, 10, 11, 12, 13 or 14 times, and is not particularly limited.

Figure BDA00024523624900001310
Corresponding to the PRB number of each hop.
When the PUCCH resource configuration information is carried in dedicated signaling, in one embodiment of the invention,
in the existing protocol, when the PUCCH resource configuration information is carried in the dedicated signaling, since the PUCCH hops 2 times at most in one slot, two parameters, namely, the starting PRB sequence number information of the first frequency hopping and the starting PRB sequence number information of the second frequency hopping, can be configured in the PUCCH resource configuration information.
Different from the existing protocol, in the embodiment of the present invention, in addition to the starting PRB sequence number information of the first frequency hopping and the starting PRB sequence number information of the second frequency hopping, the PUCCH resource configuration information may further include: PRB offset information for determining other hopping start PRB sequence numbers. The number of the PRB offset information may be only one or multiple, and based on the PRB offset information, the sequence number of other hopping start PRBs may be determined, where the other hopping refers to other hopping besides the first hopping and the second hopping.
In an embodiment of the present invention, the number of the PRB offset information may be N-2, and the N-2 PRB offset information are respectively in one-to-one correspondence with N-2 frequency hops other than the first frequency hop and the second frequency hop. And obtaining the initial PRB sequence number information of other N-2 frequency hopping based on the PRB offset information and the initial PRB sequence number information of the first frequency hopping or the initial PRB sequence number information of the second frequency hopping.
For example, when the total frequency of frequency hopping is 4, i.e., N =4, in addition to the starting PRB number information of the first frequency hopping and the starting PRB number information of the second frequency hopping, the PUCCH resource configuration information may additionally configure two pieces of PRB offset information. Assuming that the starting PRB sequence number of the first frequency hopping is starting PRB, the starting PRB sequence number of the second frequency hopping is second hopprb, and the offset RB values corresponding to the two PRB offset information are offset-1 and offset-2, respectively:
the starting PRB number of the third hop may be obtained based on (starting PRB + offset-1), and the starting PRB number of the fourth hop may be obtained based on (second hopprb + offset-2).
The starting PRB number of the third frequency hopping may be obtained based on (secondHopPRB + offset-1), and the starting PRB number of the fourth frequency hopping may be obtained based on (secondHopPRB + offset-2).
The starting PRB number of the third frequency hopping may be obtained based on (starting PRB + offset-1), and the starting PRB number of the fourth frequency hopping may be obtained based on (starting PRB + offset-2).
In another embodiment of the present invention, the number of the PRB offset information may be only one, and in this case, in addition to the starting PRB number information of the first frequency hopping and the starting PRB number information of the second frequency hopping, the PUCCH resource configuration information only needs to configure one additional PRB offset information.
Taking the offset RB value corresponding to the unique PRB offset information as offset-1 as an example, the terminal may obtain the starting PRB number for the third frequency hopping based on (startingPRB + offset-1), and obtain the starting PRB number for the fourth frequency hopping based on (secondHopPRB + offset-1).
The terminal may obtain the starting PRB number for the third frequency hopping based on (secondHopPRB + offset-1), and obtain the starting PRB number for the fourth frequency hopping based on (secondHopPRB + offset-1).
In an embodiment of the present invention, the terminal may also use the starting PRB number of the first frequency hopping as the starting PRB number of the (2K-1) th frequency hopping, and use the starting PRB number of the second frequency hopping as the starting PRB number of the 2K frequency hopping, where K is a positive integer greater than or equal to 2, and K is less than or equal to 1/2 of the total frequency hopping.
That is, the starting PRB number of the first hop is the starting PRB number of the odd hop, and the starting PRB number of the second hop is the starting PRB number of the even hop.
For example, when the total frequency of hopping is N =4, K =2, the starting PRB number starting PRB for the first hopping may be used as the starting PRB number for the third hopping. And the starting PRB number secondHopPRB of the second frequency hopping is used as the starting PRB number of the fourth frequency hopping.
In the embodiment, the starting PRB number of each frequency hopping may be determined by other methods, which is not limited by the above embodiments.
And step 13, determining a corresponding PUCCH resource based on the determined starting PRB serial number of each frequency hopping and the PUCCH resource indication information, and performing frequency hopping transmission on the determined PUCCH resource.
In a specific implementation, after the starting PRB number of each frequency hopping is determined, in combination with the PUCCH resource indication information, multiple frequency domain positions are possible, and data transmission can be performed at the determined frequency domain position.
As can be seen from the above, in the uplink data transmission method in the embodiment of the present invention, since the total frequency hopping number indicated in the PUCCH resource configuration information is greater than or equal to 2 times, the PUCCH resources in one slot are distributed in multiple frequency domain positions in the currently activated BWP, and then the terminal may transmit data at multiple frequency domain positions in the currently activated BWP, so as to enhance network coverage.
