In the 5G system, in order to support the higher-required UR LL C (Ultra Reliable and L ow L elementary communication), such as higher reliability (e.g., target B L ER is 10^ -6), lower delay (e.g., 0.5-1ms), etc., the SI (Study Item) enhanced by UR LL C of NR (New iorad, New air interface) Release16 on 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #80 total meetings is a major Study on the enhancement of the transmission reliability of PDSCH (Physical downlink Shared CHannel)/PUSCH (Physical Uplink Shared CHannel).

In a wireless communication system, a reference signal has been one of the necessary means for securing communication quality. In the high frequency band, the influence of Phase noise on the channel estimation performance is not negligible, and in NR R15, a PTRS (Phase-Tracking reference signal) is used for Phase Tracking by the receiving end, and the channel estimation accuracy is improved by performing Phase compensation in the channel estimation.

-operating a first wireless signal, a first reference signal and a first demodulation reference signal in the first set of time-frequency resource blocks;

-operating second wireless signals and second reference signals in the second set of time-frequency resource blocks;

the time domain resources occupied by the first time-frequency resource block set and the time domain resources occupied by the second time-frequency resource block set are orthogonal, and the frequency domain resources occupied by the first time-frequency resource block set and the frequency domain resources occupied by the second time-frequency resource block set are the same; the first wireless signal and the second wireless signal respectively comprise two transmissions of a first block of bits, the measurement for the first demodulation reference signal being used for demodulation of the first wireless signal and demodulation of the second wireless signal; the transmit antenna port of the first reference signal and the transmit antenna port of the second reference signal are both associated with a first antenna port, which is one transmit antenna port of the first demodulation reference signal; the pattern of the first reference signal and the pattern of the second reference signal are not the same; the operation is transmitting or the operation is receiving.

As an embodiment, the problem to be solved by the present application is: aiming at the requirement of new air interface Release16 on higher reliability, PTRS design in repeated transmission of multiple PDSCH/PUSCH is a key problem to be researched.

As an embodiment, the problem to be solved by the present application is: in order to reduce the overhead of reference signals, multiple PDSCH/PUSCH repeated transmissions share the same DMRS, i.e., the DMRS only appears in one of the multiple repeated transmissions. In this case, how to design PTRS is a key issue that needs to be studied.

As an embodiment, the essence of the above method is that the first and second radio signals are two repeated transmissions of PDSCH/PUSCH, respectively, the first and second reference signals are PTRS of the two repeated transmissions, respectively, the first demodulation reference signal is a DMRS, the DMRS is transmitted in only one of the two repeated transmissions, and the PTRS patterns of the two repeated transmissions are not the same. The advantage of using the above method is that the proposed PTRS design can be applied to the case where multiple PDSCH/PUSCH repeated transmissions share the same DMRS.

According to an aspect of the present application, the method is characterized in that the first time-frequency resource block set includes M first time-frequency resource blocks, the second time-frequency resource block set includes M second time-frequency resource blocks, the M second time-frequency resource blocks occupy the same frequency domain resources as the M first time-frequency resource blocks, respectively, and M is a positive integer; the first reference signal is transmitted in M1 of the M first time-frequency resource blocks, the second reference signal is transmitted in M1 of the M second time-frequency resource blocks, the M1 second time-frequency resource blocks occupy the same frequency domain resources as the M1 first time-frequency resource blocks, respectively, M1 is a positive integer no greater than M; a first target resource block is any one of the M1 first time-frequency resource blocks, a second target resource block is any one of the M1 second time-frequency resource blocks, a first pattern is a pattern of the first reference signal in the first target resource block, a second pattern is a pattern of the second reference signal in the second target resource block, and the first pattern and the second pattern are different; the first pattern includes T1 REs, the second pattern includes T2 REs, T1 is a positive integer, T2 is a positive integer; when T1 is greater than 1, the T1 REs are mutually orthogonal in pairs in the time domain; when T2 is greater than 1, the T2 REs are mutually orthogonal in pairs in the time domain.

According to one aspect of the present application, the above method is characterized in that said T2 and said T1 are not identical; or, the relative position of one RE in the T2 REs in the second target resource block and the relative position of any RE in the T1 REs in the first target resource block are not the same.

According to one aspect of the application, the method described above is characterized by comprising:

-receiving first information;

wherein the first information is used to indicate N1 MCS thresholds, the N1 MCS thresholds are used to determine N MCS index sets, the N MCS index sets respectively correspond to N time domain densities one-to-one, N1 is a positive integer, and N is a positive integer; the MCS index of the first wireless signal is used to determine a first time-domain density from the N time-domain densities, the MCS index of the second wireless signal is used to determine a second time-domain density from the N time-domain densities, the first time-domain density is used to determine the first pattern, and the second time-domain density is used to determine the second pattern.

According to an aspect of the present application, the method is characterized in that the MCS index of the first wireless signal and the MCS index of the second wireless signal are the same, and the first time domain density and the second time domain density are the same.

According to one aspect of the present application, the above method is characterized in that the MCS index of the first wireless signal and the MCS index of the second wireless signal are not the same; the MCS index of the first wireless signal and the MCS index of the second wireless signal both belong to the same MCS index set of the N MCS index sets, and the first time domain density and the second time domain density are the same; or the MCS index of the first wireless signal and the MCS index of the second wireless signal respectively belong to two MCS index sets of the N MCS index sets, N is greater than 1, and the first time domain density and the second time domain density are different.

As an embodiment, the essence of the above method is that the PDSCH is not included in one PDSCH/PUSCH repetition transmission corresponding to the second radio signal, and therefore, the second radio signal can be transmitted on more REs with a lower MCS index than the first radio signal.

According to an aspect of the present application, the method is characterized in that T1 is greater than 1, T2 is greater than 1, a time interval between any two temporally adjacent REs of the T2 REs is equal to the second temporal density, and a time interval between two temporally adjacent REs of the T1 REs is greater than the first temporal density.

As an embodiment, the essence of the above method is that the time interval between two adjacent REs in the T1 REs in the time domain is greater than the first time domain density, and the multicarrier symbol occupied by the DMRS is between the multicarrier symbols occupied by the two REs; since the PDSCH/PUSCH repeated transmission to which the T2 REs belong does not include the DMRS, the T2 REs are distributed at equal intervals in the time domain, so that the first pattern and the second pattern are different. The advantage of using the above method is that when the first time domain density and the second time domain density are the same, if the time domain distribution of T2 REs and the time domain distribution of T1 REs are also the same, then there will be a time interval between two REs in T2 REs that is greater than the second time domain density, and the phase tracking accuracy will be affected because the PTRS time domains are not dense enough.

According to an aspect of the present application, the above method is characterized in that a time interval of a temporally earliest one of the T2 REs with respect to the first RE is equal to the second temporal density; the first RE is one RE later in a time domain of second REs and third REs, the second RE is one RE latest in the time domain of the T1 REs, and the third RE is one RE latest in the time domain of all REs occupied by the first demodulation reference signal and occupying a same subcarrier as the T2 REs.

As an example, the essence of the above method is that the starting RE of the T2 REs is referenced to the first RE, which may also make the first pattern different from the second pattern.

-transmitting first signalling used for determining a first set of time-frequency resource blocks and a second set of time-frequency resource blocks;

As an example, compared with the conventional scheme, the method has the following advantages:

the present application proposes a PTRS design in multiple PDSCH/PUSCH repeated transmissions, in view of the requirement of new air interface Release16 for higher reliability.

To reduce the overhead of reference signals, multiple PDSCH/PUSCH repeated transmissions share the same DMRS, i.e. DMRS only appears in one of the multiple repeated transmissions. The PTRS design provided by the application can be suitable for the situation that the same DMRS is shared by repeated sending of the PDSCH/PUSCH for multiple times, and the phase tracking precision of the PTRS is ensured.

In case that multiple PDSCH/PUSCH repeated transmissions share the same DMRS, in a repeated transmission not including DMRS, since there may be more REs, the corresponding PDSCH/PUSCH may be transmitted with a lower MCS index.
