Description

[0001] This application is a divisional application of the PCT international patent application PCT / CN2018 / 083985 with an application date of April 20, 2018, which has entered the Chinese national phase with Chinese patent application number 201880042385.4 and the invention name “A method and device for determining channel frequency hopping, and computer storage medium”. Technical Field

[0002] The present invention relates to frequency hopping technology in the field of mobile communications, and in particular to a method and device for determining channel frequency hopping, and a computer storage medium. Background Art

[0003] In the Long Term Evolution (LTE) system, the Physical Uplink Control Channel (PUCCH) can use frequency hopping technology to obtain frequency domain diversity gain and improve channel transmission performance. In LTE, the first and second steps of PUCCH frequency hopping are symmetrical with the center mirror of the system bandwidth, such as Figure 1 As shown, the distance between the first step and the lower edge of the system bandwidth is consistent with the distance between the second step and the upper edge of the system bandwidth, both of which are D.

[0004] The above design for PUCCH frequency hopping can distribute PUCCH on both sides of the system bandwidth, so as to leave the central part of the system bandwidth for data channels, such as the physical uplink shared channel (PUSCH), but it will cause different PUCCH frequency hopping steps for different terminals. Figure 2 As shown in the figure, some terminals have a larger frequency hopping step size, and the PUCCH is closer to the edge of the system bandwidth, with better frequency domain diversity and better transmission performance; while other terminals have a smaller frequency hopping step size, and the PUCCH is closer to the center of the system bandwidth, with worse frequency domain diversity and poorer transmission performance. It can be seen that the traditional PUCCH frequency hopping design causes the PUCCH frequency hopping step size to be unstable, which leads to a decrease in the PUCCH transmission performance of some terminals when the PUCCH capacity is large.

[0094] In order to enable a more detailed understanding of the features and technical contents of the embodiments of the present invention, the implementation of the embodiments of the present invention is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not intended to limit the embodiments of the present invention.

[0095] The fifth generation mobile communication (5G NR) system is the research direction of future mobile communication systems. In the 5G NR system, on the one hand, in order to increase the flexibility of frequency domain resource allocation and reduce terminal power consumption, 5G NR terminals can transmit signals in bandwidth segments (Bandwidth Part) that are smaller than the system bandwidth. When the bandwidth of the bandwidth segment is small, the frequency hopping step of the PUCCH located in the center will be further reduced, affecting the PUCCH transmission performance. On the other hand, since 5G NR introduces a series of new technologies, such as the new Multiple-Input Multiple-Output (MIMO) technology, a larger number of channel state information reports (CSI reports) are required, and the PUCCH load is greatly increased, which will cause the PUCCH to occupy a larger proportion of frequency domain resources in the bandwidth segment, and the PUCCH frequency hopping step near the center of the bandwidth segment becomes smaller, and the transmission performance is further deteriorated.

[0096] To this end, an embodiment of the present invention proposes a method for determining channel frequency hopping, which can achieve a stable frequency hopping step size under a given bandwidth segment broadband size, thereby obtaining a more stable frequency domain diversity gain and improving the transmission performance of the uplink channel (especially the uplink control channel).

[0097] Figure 3 FIG. 1 is a flow chart of a method for determining channel frequency hopping according to an embodiment of the present invention. Figure 3 As shown, the method for determining channel frequency hopping includes the following steps:

[0098] Step 301: The terminal determines a first bandwidth corresponding to a bandwidth segment, where the first bandwidth corresponding to the bandwidth segment is smaller than a second bandwidth corresponding to the system bandwidth.

[0099] In the embodiment of the present invention, the type of terminal is not limited, and the terminal can be any type such as a mobile phone, a notebook, a tablet computer, a desktop computer, a vehicle-mounted terminal, a smart home terminal, etc.

[0100] In the embodiment of the present invention, the bandwidth supported by the base station is referred to as the system bandwidth, that is, the second bandwidth. In LTE, the terminal can transmit signals within the entire system bandwidth. In the 5G NR system, the terminal only transmits signals in a part of the system bandwidth. Here, a part of the system bandwidth is called a bandwidth segment. Bandwidth segmentation can effectively improve the resource utilization efficiency of the system bandwidth.

[0101] In the embodiment of the present invention, the uplink channel can be transmitted in a frequency hopping manner. Taking the frequency hopping including two steps as an example, the difference between the first step of the frequency hopping and the second step of the frequency hopping in the frequency domain is the frequency hopping step length. The size of the frequency hopping step length determines the frequency domain diversity gain of the uplink channel. The larger the frequency hopping step length, the larger the frequency domain diversity gain of the uplink channel. On the contrary, the smaller the frequency hopping step length, the smaller the frequency domain diversity gain of the uplink channel. In order to obtain a stable and large frequency domain diversity gain, the embodiment of the present invention determines the frequency hopping step length corresponding to the uplink channel based on the first bandwidth corresponding to the bandwidth segment, so as to improve the transmission performance of the uplink channel (especially the uplink control channel).

[0102] Specifically, the terminal needs to first determine the first bandwidth corresponding to the bandwidth segment. Obviously, the first bandwidth corresponding to the bandwidth segment is smaller than the second bandwidth corresponding to the system bandwidth.

[0103] In the embodiment of the present invention, the terminal receives first configuration information, and determines a first bandwidth corresponding to the bandwidth segment based on the first configuration information.

[0104] Here, the terminal may receive the first configuration information in the following two ways:

[0105] Method 1: The terminal receives RRC signaling carrying the first configuration information.

[0106] Method 2: The terminal receives system information carrying the first configuration information.

[0107] In the above solution, the number of first configuration information received by the terminal may be one or more, where more means greater than or equal to two.

[0108] When the terminal receives a first configuration information, the terminal determines a first bandwidth corresponding to the bandwidth segment based on the first configuration information.

[0109] When the terminal receives a plurality of first configuration information, it determines a plurality of candidate first bandwidths corresponding to the bandwidth segment based on the plurality of first configuration information; and selects a first bandwidth corresponding to the bandwidth segment from the plurality of candidate first bandwidths.

[0110] Here, the terminal receives a first control signaling, and selects a first bandwidth corresponding to the bandwidth segment from the multiple candidate first bandwidths according to the first control signaling. The first control signaling is: DCI, or MAC CE.

[0111] Step 302: The terminal determines a frequency hopping step corresponding to an uplink channel based on a first bandwidth corresponding to the bandwidth segment.

[0112] In the embodiment of the present invention, the terminal determines the frequency hopping step length corresponding to the uplink channel based on the following formula: H =nW,

[0113] Among them, W H is the frequency hopping step corresponding to the uplink channel, W is the first bandwidth corresponding to the bandwidth segment, n is the proportional coefficient, n=1 / m, and m is a positive integer greater than 1.

[0114] Based on the formula W H =nW determines the W H hour, or in, represents the smallest integer greater than nW, Represents the largest integer less than nW.

[0115] Considering that the frequency hopping step length is equal to an integer multiple of the frequency domain scheduling unit, it is practically meaningful. H The value of is an integer.

[0116] For example, n may be 1 / 2, 1 / 4, etc. Different terminals may correspond to the same n value, or different terminals may correspond to different n values.

[0117] In the above scheme, the terminal needs to first determine n or W HSpecifically, the terminal determines the n or W based on a preset value. H Or, the terminal receives the second configuration information, and determines the n or W based on the second configuration information H .

[0118] Here, the terminal may receive the second configuration information in the following two ways:

[0119] Method 1: The terminal receives RRC signaling carrying the second configuration information.

[0120] Method 2: The terminal receives system information carrying the second configuration information.

[0121] In one embodiment of the present invention, the second configuration information and the first configuration information are the same configuration information.

[0122] In the above solution, the number of second configuration information received by the terminal may be one or more.

[0123] When the terminal receives a second configuration information, it determines the n or W based on the second configuration information. H .

[0124] When the terminal receives multiple second configuration information, it determines multiple candidate n or W based on the multiple second configuration information. H ; From the plurality of candidates n or W H Select the n or W H .

[0125] Here, the terminal receives a second control signaling, and selects from the plurality of candidate n or W according to the second control signaling. H Select the n or W H The second control signaling is: DCI or MAC CE.

[0126] In one embodiment of the present invention, the second control signaling and the first control signaling are the same control signaling.

[0127] Step 303: The terminal determines a frequency domain position for transmitting an uplink channel based on the frequency hopping step corresponding to the uplink channel.

[0128] In an embodiment of the present invention, the terminal determines the frequency domain position of the second step of frequency hopping based on the frequency domain position of the first step of frequency hopping and the frequency hopping step length corresponding to the uplink channel; wherein the frequency domain position of the first step of frequency hopping and the frequency domain position of the second step of frequency hopping are the frequency domain positions used to transmit the uplink channel.

[0129] Here, the terminal receives a third control signaling, and determines the frequency domain position of the first step of the frequency hopping based on the third control instruction. Wherein, the third control signaling is: DCI or MAC CE.

[0130] In the embodiment of the present invention, the third control signaling is the same control signaling as at least one of the following: the first control signaling and the second control signaling.

[0131] The technical solution of the embodiment of the present invention is further described in detail below in conjunction with specific application examples.

[0135] In one embodiment, for multiple terminals using the same bandwidth segment, the same W H For example, if the bandwidth size of bandwidth segment 1 is W1 and the bandwidth size of bandwidth segment 2 is W2, then multiple terminals in bandwidth segment 1 use the same W H =W1 / 2, multiple terminals in bandwidth segment 2 use the same W H =W2 / 2.

[0136] In another embodiment, for multiple terminals using bandwidth segments of the same size, the same W H For example, if the bandwidth size of bandwidth segment 1 and bandwidth segment 2 is W, then multiple terminals in bandwidth segment 1 and bandwidth segment 2 use the same W. H =W / 2.

For multiple terminals using the same bandwidth segment or bandwidth segment of the same size, different W H Configuration, such as W of terminal 1 H =W / 4, W of terminal 2 H =W / 2, that is, terminal 1 and terminal 2 use different n configurations, that is, n=4 for terminal 1 and n=2 for terminal 2.
