Embodiment 1

[0288] Assuming that UE1 works in the first bandwidth BW1 of 100 PRB, BW1 has a bandwidth BW2 of 75 PRB and a bandwidth BW3 of 25 PRB, the terminals working in these two bandwidths are respectively recorded as UE2 and UE3, and the second bandwidth set is BW2 and BW3. The base station determines BW2 as the third bandwidth in the second bandwidth set {BW2, BW3}, and notifies UE1 to perform frequency hopping transmission within the third bandwidth. like Figure 11 As shown, if the base station uses two offset location parameters to notify UE1, then After the adjustment, the actual physical resource positions of the low-frequency part are all increased by an offset of 25 PRBs, and the actual physical resource positions of the high-frequency part remain unchanged. Figure 11 The shaded physical resource block numbers 25, 26, 98 and 99 are the resource multiplexing of the uplink control channel of UE1 and UE2 after the resource position adjustment is performed.

Embodiment 2

[0290] Assuming that UE1 works in the first bandwidth BW1 of 200PRB, and there are bandwidths BW2 of 100PRB and BW3 of 50PRB in BW1, the terminals working in these two bandwidths are respectively recorded as UE2 and UE3, and BW2 also includes BW3. like Figure 12 As shown, the base station determines the minimum bandwidth BW3 in the bandwidth set {BW2, BW3}, and notifies UE1 of the specific location of BW3, and UE1 performs frequency hopping transmission within the range of BW3 after receiving the notification. At the same time, the base station determines and informs UE2 that frequency hopping transmission also needs to be performed in BW3. Figure 12 The shaded part is UE1, UE2 and UE3 are multiplexed and transmitted in BW3.

Embodiment 3

[0292] It is assumed that UE1 works in the first bandwidth BW1 of 100 PRB, and there are bandwidths BW2 of 50 PRB and BW3 of 50 PRB in BW1, and terminals that work in these two bandwidths are respectively denoted as UE2 and UE3. It is assumed that UE1 occupies two PRB pairs at both ends of BW1, UE2 occupies one PRB pair at both ends of BW2, and UE3 occupies two PRB pairs at both ends of BW3. The base station needs to notify UE2 and UE3 to adjust the physical resources of the uplink control channel. like Figure 13 As shown, it is assumed that the base station determines two location offset parameters according to the physical resources of the control channel occupied by UE1 on BW1 and For UE2, The position of the low-frequency part remains unchanged, and the physical resource block position number of the high-frequency part is reduced by 2, which is actually from n PRB =97 start mapping; for UE3, The physical resource position of the high-frequency part remains unchan...

Abstract

The embodiment of the invention provides a frequency hopping transmission method, a terminal, a base station and a computer readable storage medium. The method comprises the steps that the base station transmits a notification instruction for adjusting the physical resource location of the uplink control channel frequency hopping transmission to the terminal, and the terminal adjusts the physicalresource location of the uplink control channel frequency hopping transmission according to the above notification instruction.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method, terminal, base station and computer-readable storage medium for frequency hopping transmission. Background technique [0002] With the development and changes of mobile communication service requirements, many organizations such as ITU (International Telecommunication Union) have begun to study new wireless communication systems (ie 5G NR, 5 Generation New RAT (Fifth Generation New Wireless Communication Technology) for future mobile communication systems. )). Different terminals in 5G may have different working bandwidths. When there are multiple terminals working in different working bandwidths and the bandwidths overlap, and need to transmit the uplink control channel using frequency hopping within the same time interval, there may be an upper frequency hopping (high frequency) part and a lower frequency hopping (low frequency) part One of the...
