Embodiment 1

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

Embodiment 2

[0290] Assuming that UE1 works at the first bandwidth BW1 of 200PRB, there are bandwidth BW2 of 100PRB and bandwidth BW3 of 50PRB in BW1, terminals working at these two bandwidths are respectively marked as UE2 and UE3, and BW2 also includes BW3. Such as Figure 12 As shown, the base station determines the minimum bandwidth BW3 in the bandwidth set {BW2, BW3}, and notifies UE1 of the determined 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 notifies UE2 that it also needs to perform frequency hopping transmission in BW3. Figure 12 The shaded part is that UE1, UE2 and UE3 perform multiplex transmission in BW3.

Embodiment 3

[0292] Assuming that UE1 works in the first bandwidth BW1 of 100 PRB, there are bandwidth BW2 of 50 PRB and bandwidth BW3 of 50 PRB in BW1, and the terminals working in these two bandwidths are marked as UE2 and UE3 respectively. 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 resource of the uplink control channel. Such as Figure 13 As shown in , it is assumed that the base station determines two position 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 position number of the physical resource block of the high-frequency part is reduced by 2, actually from n PRB =97 start mapping; for UE3, The physical resource position of the high-frequency part remains u...

Abstract

An embodiment of the present invention provides a method for frequency hopping transmission, a terminal, a base station, and a computer-readable storage medium. The method includes: the base station sends a notification signaling to the terminal to adjust the physical resource location of the frequency hopping transmission of the uplink control channel, and the The terminal adjusts the physical resource position of the frequency hopping transmission of the uplink control channel according to the notification signaling.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method for frequency hopping transmission, a terminal, a base station, and a computer-readable storage medium. Background technique [0002] With the development and change of mobile communication service requirements, many organizations such as ITU (International Telecommunication Union) have begun to study new wireless communication systems (namely 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 with overlapping bandwidths and need to transmit the uplink control channel using frequency hopping in the same time interval, there may be an upper frequency hopping (high frequency) part and a lower frequency hopping (low frequency) part One o...
