In 5G systems, to support higher-demand URLLC (Ultra Reliable and Low Latency Communication, ultra high reliability and ultra low latency communication) traffic, such as higher reliability (e.g., target BLER of 10-6), lower latency (e.g., 0.5-1 ms), etc., NR (New Radio) Release 16 URLLC enhanced SI (Study Item) was passed through 3GPP (3 rd Generation Partner Project, third Generation partnership project) RAN (Radio Access Network ) #80 full-scale. Among them, enhancement of transmission reliability of PDSCH (Physical Downlink Shared CHannel )/PUSCH (Physical Uplink Shared CHannel, physical uplink shared channel) is an important research point.

In the high frequency band, the influence of Phase noise on the channel estimation performance is not ignored, in NR 15, PTRS (Phase-Tracking Reference Signal, phase tracking reference signal) is used by the receiving end for Phase tracking, and the channel estimation accuracy is improved by performing Phase compensation in the channel estimation.

Disclosure of Invention

The inventor finds that in the new air interface Release 16, repeated transmission of the PDSCH/PUSCH is a key technology under study, and can meet the requirement of higher reliability of the URLLC service. At this time, PTRS design in multiple repetition transmission is a key issue to consider.

As one embodiment, the problem to be solved by the present application is: the PTRS design in multiple PDSCH/PUSCH repetition transmissions is a key issue that needs to be studied for the new air interface Release16 requirement for higher reliability.

As one embodiment, the problem to be solved by the present application is: in order to reduce the overhead of the reference signal, the multiple PDSCH/PUSCH repetition transmissions share the same DMRS, i.e., the DMRS occurs only in one repetition transmission of the multiple repetition 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 radio signal and the second radio signal are respectively two repeated transmissions of PDSCH/PUSCH, the first reference signal and the second reference signal are respectively PTRS of the two repeated transmissions, 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 different. The advantage of adopting the method is that the PTRS design can be suitable for the situation that the same DMRS is shared by multiple repeated PDSCH/PUSCH transmissions.

According to an aspect of the present application, the above method is characterized in that the first set of time-frequency resource blocks includes M first time-frequency resource blocks, the second set of time-frequency resource blocks includes M second time-frequency resource blocks, and the M second time-frequency resource blocks occupy the same frequency domain resources as the M first time-frequency resource blocks, respectively, where M is a positive integer; the first reference signal is sent in M1 first time-frequency resource blocks in the M first time-frequency resource blocks, the second reference signal is sent in M1 second time-frequency resource blocks in the M second time-frequency resource blocks, the M1 second time-frequency resource blocks and the M1 first time-frequency resource blocks occupy the same frequency domain resource respectively, and M1 is a positive integer not greater than M; the first target resource block is any one of the M1 first time-frequency resource blocks, the second target resource block is any one of the M1 second time-frequency resource blocks, the first pattern is a pattern of the first reference signal in the first target resource block, the 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 comprises T1 RE, the second pattern comprises T2 RE, T1 is a positive integer, and T2 is a positive integer; when T1 is greater than 1, the T1 REs are mutually orthogonal in the time domain; when T2 is greater than 1, the T2 REs are orthogonal to each other in the time domain.

According to one aspect of the 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 RE in the second target resource block is different from the relative position of any RE in the T1 RE in the first target resource block.

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

-receiving first information;

the first information is used for indicating N1 MCS thresholds, the N1 MCS thresholds are used for determining N MCS index sets, the N MCS index sets are respectively in one-to-one correspondence with N time domain densities, 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 radio signal and the MCS index of the second radio signal are the same, and the first time domain density and the second time domain density are the same.

According to an 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 identical; 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 in 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 DMRS is not included in one PDSCH/PUSCH repetition transmission corresponding to the second radio signal, so the second radio signal may 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 time-domain adjacent REs of the T2 REs is equal to the second time-domain density, and a time interval between two time-domain adjacent REs of the T1 REs is greater than the first time-domain density.

As an embodiment, the essence of the above method is that a time interval between two time-domain adjacent REs of the T1 REs is greater than the first time-domain density, and a multicarrier symbol occupied by the DMRS is between multicarrier symbols occupied by the two REs; in one PDSCH/PUSCH repeated transmission to which the T2 REs belong, since the DMRS is not included, the T2 REs are equally spaced 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 the time interval between two REs in T2 REs will be greater than the second time domain density, and then the PTRS time domains will be not dense enough, which will affect the phase tracking accuracy.

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

The PTRS design provided by the application can be suitable for the condition that the same DMRS is shared by repeated transmission of the PDSCH/PUSCH for multiple times, and ensures the phase tracking precision of the PTRS.

In case of multiple PDSCH/PUSCH repetition transmissions sharing the same DMRS, in one repetition transmission excluding the DMRS, the corresponding PDSCH/PUSCH may be transmitted with a lower MCS index, since there may be more REs.

Layer 1 (L1 layer) is the lowest layer and implements various PHY (physical layer) signal processing functions. The L1 layer will be referred to herein as PHY301.
