Description

Method and device for determining channel frequency hopping

In a Long Term Evolution (LTE, Long Term Evolution) system, a Physical Uplink Control Channel (PUCCH, Physical Uplink Control CHannel) may adopt a 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 mirror-symmetrical at the center of the system bandwidth. As shown in Figure 1, the distance between the first step and the lower edge of the system bandwidth and the second step and the system frequency The distance between the wide upper edge remains the same, both are D.

The above-mentioned design for PUCCH frequency hopping can distribute PUCCH on both sides of the system bandwidth, so that the central part of the system bandwidth is reserved for the data channel, such as PUSCH (Physical Uplink Shared Channel), but it will cause different terminals The PUCCH frequency hopping step size is different. As shown in Figure 2, some terminals have a larger frequency hopping step, and the PUCCH is closer to the edge of the system bandwidth, with better frequency-domain diversity effect and better transmission performance; while other terminals have a smaller frequency hopping step, and the PUCCH is more efficient. Close to the center of the system bandwidth, the frequency domain diversity effect is worse, and the transmission performance is poor.

In order to have a more detailed understanding of the features and technical contents of the embodiments of the present application, the implementation of the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

The fifth generation mobile communication (5G NR) system is the research direction of the future mobile communication system. In the 5G NR system, on the one hand, in order to increase the flexibility of frequency domain resource allocation and reduce the power consumption of the terminal, the 5G NR terminal can transmit signals in a bandwidth part smaller than the system bandwidth. When the bandwidth of the segment is small, the frequency hopping step size of the central PUCCH will be further reduced, which affects the PUCCH transmission performance. On the other hand, due to the introduction of a series of new technologies in 5G NR, such as the new Multiple-Input Multiple-Output (MIMO) technology, a larger number of channel status information reports (CSI reports) are required, and the load on the PUCCH is greatly increased. If it increases, this will cause the PUCCH to occupy a larger proportion of frequency domain resources in the bandwidth segment, and the frequency hopping step size of the PUCCH near the center of the bandwidth segment will become smaller, and the transmission performance will be further deteriorated.

To this end, an embodiment of the present application proposes a method for determining channel frequency hopping, which can achieve a stable frequency hopping step size under the condition of a given broadband size of a bandwidth segment, so as to obtain a more stable frequency domain diversity gain, The transmission performance of the upstream channel (especially the upstream control channel) is improved.

FIG. 3 is a schematic flowchart of a method for determining channel frequency hopping according to an embodiment of the present application. As shown in FIG. 3 , the method for determining channel frequency hopping includes the following steps:

Step 301: The terminal determines the first bandwidth size corresponding to the bandwidth segment, where the first bandwidth size corresponding to the bandwidth segment is smaller than or equal to the carrier bandwidth size.

In the embodiment of the present application, the type of the terminal is not limited, and the terminal may be any type, such as a mobile phone, a notebook, a tablet computer, a desktop computer, a vehicle-mounted terminal, and a smart home terminal.

In the embodiments of the present application, the bandwidth supported by the base station is referred to as the system bandwidth. In LTE, terminals can transmit signals over the entire system bandwidth. In the 5G NR system, the terminal is only in the system A part of the system bandwidth is used to transmit signals. Here, a part of the system bandwidth is called a bandwidth segment. The bandwidth segment can effectively improve the resource utilization efficiency of the system bandwidth.

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

Specifically, the terminal needs to first determine the first bandwidth size corresponding to the bandwidth segment. Obviously, the first bandwidth size corresponding to the bandwidth segment is less than or equal to the carrier bandwidth size.

When receiving a first configuration message, the terminal determines a first bandwidth size corresponding to the bandwidth segment based on the one first configuration message.

When receiving multiple first configuration messages, the terminal determines multiple candidate first bandwidth sizes corresponding to the bandwidth segment based on the multiple first configuration messages; The first bandwidth size corresponding to the bandwidth segment is selected from the size.

Here, the terminal receives a first control signal, and selects a first bandwidth size corresponding to the bandwidth segment from the plurality of candidate first bandwidth sizes according to the first control signal. Wherein, the first control signal is: DCI or MAC CE.

Step 302: The terminal determines the frequency hopping step size corresponding to the uplink channel based on the first bandwidth size corresponding to the bandwidth segment.

In the embodiment of the present application, the terminal determines the frequency hopping step size corresponding to the uplink channel based on the following formula: W _H =nW, where W _H is the frequency hopping step size corresponding to the uplink channel, and W is the first frequency corresponding to the bandwidth segment.

Manner 2: The terminal receives the system message carrying the second configuration message.

In an embodiment of the present application, the second configuration message and the first configuration message are the same configuration message.

In the above solution, the number of second configuration messages received by the terminal may be one or more.

When the terminal receives one second configuration message, the terminal determines the n or _WH based on the one second configuration message.

When the terminal receives multiple second configuration messages, it determines multiple candidates n or _WH based on the multiple second configuration messages; and selects the n or _WH from the multiple candidates n or _WH .

Here, the terminal receives a second control signal, and selects the n or WH from the plurality of candidates n or _WH according to the second control signal. Wherein, the second control signal is: DCI or MAC CE.

In an embodiment of the present application, the second control signal and the first control signal are the same control signal.
