Detailed Description
The following describes the detailed implementation of the embodiments of the present invention with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the invention, are not intended to limit the invention.
For a better understanding of embodiments of the present invention, the following terms related to embodiments of the present invention will be described.
1. Radio channel frequency selectivity: also known as radio channel frequency selectivity. In a wireless communication system, complex and diverse spatial patterns form an integrated electromagnetic wave propagation environment, the spatial patterns have corresponding physical dimensions, propagation characteristics of electromagnetic waves with different frequencies are different, and channel response of the electromagnetic waves is continuously changed along with the change of the frequencies of the electromagnetic waves transmitted in the spatial patterns, so that frequency selectivity is formed. The radio channel frequency selectivity can be approximately characterized by the size of the coherence bandwidth of the channel, which in turn can be approximately equivalent to the inverse of the maximum multipath delay, so that the frequency selectivity of the current radio channel environment can be inferred by estimating the maximum multipath delay of the channel. In general, when the terminal performs delay spread estimation, the actual wireless channel environment is divided into different gears according to the delay spread, and the higher the gear is, the larger the maximum multipath delay is. Thus, embodiments of the present invention will characterize the wireless channel frequency selectivity by its maximum multipath delay profile.
2. Frequency domain resources: i.e. all resources available in the frequency domain, the number of frequency domain resources is characterized in the embodiment of the invention by the number of RBs (Resource blocks).
The embodiment of the invention provides a control method for frequency hopping transmission of a PUSCH, which is applied to a terminal. In which fig. 1 shows a wireless communication system formed by one base station 100 and a plurality of terminals 200, preferably a 5G NR mobile communication system, wherein the terminals may be various types of electronic devices having information processing capability in the course of implementation, and may include, for example, computers, cellular phones, digital phones, video phones, televisions, sensing devices, etc.
Returning to the embodiment of the invention, the control method of the corresponding frequency hopping transmission of the PUSCH comprises the following steps: a main judging step of controlling the execution or the abandonment of the frequency hopping transmission according to the number of available frequency domain resources configured by the base station; and a supplementary judgment step of controlling execution or discarding of the frequency hopping transmission according to the current radio channel frequency selectivity in the case where the main judgment step determines to execute the frequency hopping transmission.
For the main judging step, the number of RBs can be used for representing the number of available frequency domain resources. When the number of available RBs is smaller, for example, smaller than a certain threshold value, if frequency hopping transmission is performed, the performance of channel estimation and parameter estimation is greatly reduced at this time, so that the data demodulation performance is affected.
In addition to the number of available frequency domain resources, the radio channel frequency selectivity has an influence on the frequency domain diversity gain and the like. Specifically, when the environmental frequency selectivity of the wireless channel is weak, frequency hopping transmission is adopted, and on the premise of reducing the performance of channel estimation and parameter estimation, the obtained frequency domain diversity gain is greatly reduced because the relevant bandwidth of the channel is larger (the propagation characteristics of the channel in the relevant bandwidth to electromagnetic waves with different frequencies basically remain unchanged). Therefore, the embodiment of the invention further designs a supplementary judging step, namely after the main judging step, continuously judging whether the wireless channel frequency selectivity is in a preset weak frequency selectivity range, if so, discarding the frequency hopping transmission, otherwise, executing the frequency hopping transmission.
In this way, the embodiment of the invention does not directly carry out frequency hopping transmission on the PUSCH according to the frequency hopping instruction of the base station, but judges based on the available frequency domain resource number configured by the base station and the wireless channel frequency selectivity, so that under the scene of smaller available RB number and weaker wireless channel frequency selectivity, the frequency hopping transmission can be selected to be abandoned, and the robustness of the PUSCH transmission is improved.
In a preferred embodiment, before performing the main judging step, the control method further includes: and a pre-judging step, namely acquiring and analyzing the PUSCH frequency hopping indication from the base station to determine whether the PUSCH frequency hopping indication indicates to enable frequency hopping transmission, if so, executing the main judging step, otherwise, giving up the frequency hopping transmission. That is, the pre-judging step is to judge whether the frequency hopping instruction received by the terminal from the base station enables the frequency hopping transmission, if so, continuing the main judging step, otherwise, discarding the frequency hopping transmission.
In a preferred embodiment, the embodiment of the present invention may form a three-step "sequential" decision strategy based on PUSCH frequency hopping indication, frequency domain resource number, and radio channel frequency selectivity, the steps of which are shown in fig. 2.
Fig. 2 shows a flow of a control method for frequency hopping transmission of PUSCH in an example of an embodiment of the present invention. As shown in fig. 2, an exemplary control method may include the following steps S1-S3.
And step S1, controlling the execution or the discarding of the frequency hopping transmission according to the PUSCH frequency hopping instruction from the base station.
Step S2, in the case that the step S1 determines to execute the frequency hopping transmission, controlling the execution or the abandonment of the frequency hopping transmission according to the number of currently available frequency domain resources configured by the base station.
And step S3, controlling the execution or the abandonment of the frequency hopping transmission according to the current wireless channel frequency selectivity under the condition that the step S2 determines to execute the frequency hopping transmission.
Wherein steps S1, S2 and S3 correspond to the above-mentioned pre-judgment step, main judgment step and supplementary judgment step, respectively. The PUSCH hopping instruction from the base station to the terminal and the number of available frequency domain resources may be specified by a protocol.
For step S1, for example, the terminal parses a PUSCH hopping indication from the base station, where the PUSCH hopping indication is used to indicate whether to enable frequency hopping transmission, if so, other determining steps are continued, and if not, non-frequency hopping transmission is directly performed.
For step S3, for example, the wireless channel frequency selectivity is characterized by a maximum multipath delay profile of the wireless channel, and the weak frequency selectivity range is configured to define that the maximum multipath delay profile is less than or equal to a preset gear threshold. Accordingly, the maximum multipath time delay of the wireless channel is recorded as Tmax, the channel coherence bandwidth is recorded as Bc (1/Tmax), so that when the maximum multipath time delay gear value TmaxTh is judged to be smaller than or equal to the gear threshold TrmsTh1 (namely TmaxTh is smaller than or equal to TrmsTh1, for example TmaxTh is gear 0, tmaxTh1 is gear 1), the maximum multipath time delay of the channel is small, namely the relevant bandwidth of the wireless channel is larger, and the channel coherence bandwidth belongs to a scene with weaker wireless channel frequency selectivity, and the frequency hopping transmission is abandoned, so that the parameter estimation and channel estimation performance can be improved, and the complexity of terminal transmission can be reduced; otherwise, the terminal performs the PUSCH transmission in a frequency hopping mode. It should be noted that, after the frequency hopping transmission is abandoned, PUSCH transmission in a non-frequency hopping mode can be normally performed.
For step S2, controlling the execution or discarding of the frequency hopping transmission according to the number of available frequency domain resources configured by the base station includes: discarding the frequency hopping transmission when the number of available frequency domain resources is smaller than or equal to a preset first resource threshold; executing step S3 when the number of available frequency domain resources is greater than the first resource threshold and less than or equal to a second resource threshold; and performing the frequency hopping transmission when the number of available frequency domain resources is greater than the second resource threshold. Wherein the first resource threshold is less than the second resource threshold.
For example, the number of frequency domain resources is represented by RB number, denoted RBNum, and a first RB threshold FreRBTh and a second RB threshold FreRBTh2 are configured, which correspond to the first resource threshold and the second resource threshold, respectively. Accordingly, as shown in FIG. 3, the following steps S21-S24 may be included.
In step S21, the terminal obtains the number RBNum of RBs currently available. The terminal obtains the available RBNum for the current period configuration, for example, by parsing the information obtained from the base station.
Step S22, if RBNum is less than or equal to FreRBTh, the frequency hopping transmission is abandoned, and the non-frequency hopping transmission is directly carried out. This is because the number of RBs is too small, pilot REs available for channel estimation and parameter estimation are too small, and further the frequency domain filtering cannot perform sliding filtering, and the extrapolated data REs have a large duty cycle, which reduces the performance of channel estimation and parameter estimation.
Step S23, if RBNum is greater than FreRBTh but less than FreRBTh, the judgment based on the radio channel frequency selectivity is continued (corresponding to step S3).
Step S24, if RBNum is greater than FreRBTh2, frequency hopping transmission is performed. In this case, the number of currently available frequency domain resources is relatively large, and even if frequency hopping transmission is performed, the performance of channel estimation and parameter estimation is not greatly affected, so that the PUSCH transmission can be performed in a frequency hopping manner directly according to the frequency hopping instruction configured by the base station.
Thus, in this example, for the frequency hopping transmission of the PUSCH, a three-step judgment strategy based on the PUSCH frequency hopping indication, the frequency domain resource number and the radio channel frequency selectivity is given, and when the base station indicates that the frequency hopping indication is enabled, the frequency hopping transmission can be selectively abandoned in the scene that the available RB number is less and the radio channel frequency selectivity is weaker, so as to improve the robustness of the PUSCH transmission and the applicability of the PUSCH transmission in various scenes.
Based on the same inventive concept as the control method of the above embodiment, as shown in fig. 4, an embodiment of the present invention further provides a control device for PUSCH frequency hopping transmission, including: the main judging module is used for controlling the execution or the abandonment of the frequency hopping transmission according to the number of the available frequency domain resources configured by the base station; and the supplementing judging module is used for controlling the execution or the abandonment of the frequency hopping transmission according to the current wireless channel frequency selectivity under the condition that the main judging module determines to execute the frequency hopping transmission.
In a preferred embodiment, the control device further comprises: and the pre-judging module is used for acquiring and analyzing the PUSCH frequency hopping indication from the base station before executing the main judging module so as to determine whether the PUSCH frequency hopping indication indicates to enable frequency hopping transmission, if yes, executing the main judging device, and otherwise, discarding the frequency hopping transmission.
In a more preferred embodiment, the supplemental determination module controlling the performance or the discard of the frequency hopping transmission according to the radio channel frequency selectivity includes: judging whether the wireless channel frequency selectivity is in a preset weak frequency selectivity range, if so, discarding the frequency hopping transmission, otherwise, executing the frequency hopping transmission.
In a more preferred embodiment, the main determining module is configured to control the performing or discarding of the frequency hopping transmission according to the number of available frequency domain resources configured by the base station, including: discarding the frequency hopping transmission when the number of available frequency domain resources is smaller than or equal to a preset first resource threshold; executing the supplementary judgment module when the number of available frequency domain resources is greater than the first resource threshold and less than or equal to a second resource threshold; and performing the frequency hopping transmission when the number of available frequency domain resources is greater than the second resource threshold. Wherein the first resource threshold is less than the second resource threshold.
