Embodiment 1

[0139] The initial PDSCH repetition can include multiple times, the initial PDSCH duplicate TCI mapping is based on seqmapping.

[0140]Image 6 The last four initial PDSCH transfers are shown in Slot N, Slot N + 1, Slot N + 2, and Slot N + 3.

[0141] like Image 6 A shows that the two initial PDSCH transfers on the SLOT N + 2 and SLOT N + 3 slots have uplink symbols (represented by "U"), then the PDSCH on both slot can be Drop; in Drop is not available. After the initial PDSCH transmission, two real PDSCH transmissions were obtained, which were located on Slot N and Slot N + 1 slots. These two real PDSCH transport correspond to the same TCI State (TCI State 1, shown in the figure).

[0142] A PDSCH transmission located on the SLOT N slot can be referred to as the first real PDSCH transmission, and the PDSCH transmission located on the SLOT N + 1 slot is called the second real PDSCH transmission.

[0143] like Image 6 B shows that two initial PDSCH transmission on Slot N + 2 and Sl...

Embodiment 2

[0145] The initial PDSCH repetition can include multiple times, the initial PDSCH repeated TCI mapping is based on cycmapping.

[0146] Figure 7 The last four initial PDSCH transfers are shown in Slot N, Slot N + 1, Slot N + 2, and Slot N + 3.

[0147] like Figure 7 A shows that the two initial PDSCH transfers on the SLOT N + 1 and SLOT N + 3 slots have uplink symbols (represented by "U"), and the PDSCH on both slot can be Drop; not available in DROP. After the initial PDSCH transmission, two real PDSCH transmissions are obtained, which are located on Slot N and Slot N + 2 slots. These two real PDSCH transport correspond to the same TCI State (TCI State 1, shown in the figure).

[0148] The PDSCH transmission located on the SLOT N slot can be called the first real PDSCH transmission, and the PDSCH transmission located on the SLOT N + 2 slot is referred to as the second real PDSCH transmission.

[0149] like Figure 7 B shows that two initial PDSCH transmission on Slot N + 1 and Sl...

Embodiment 3

[0151] PUSCH repeat belongs to the PUSCH Repetition Type A.

[0152] The initial PUSCH repetition can include multiple times, the initial PUSCH duplicate TCI mapping is based on seqmapping.

[0153] Figure 8 The last four initial PUSCH transmission is shown, which is located on the four slot of Slot N, Slot N + 1, Slot N + 2 and Slot N + 3.

[0154] like Figure 8 A shows that two initial PUSCH transmission on Slot N + 2 and Slot N + 3 slots have downlink symbols (represented by "D"), the PUSCH on both slot can be Drop; not available in Drop; After the initial PUSCH transmission, two real PUSCH transmissions are obtained, which are located on Slot N and Slot N + 1 slots. These two real PUSCH transport correspond to the same TCI State (TCI State 1, shown in the figure).

[0155] The PUSCH transmission located on the SLOT N slot can be called the first real PUSCH transmission, and the PUSCH transmission located on the SLOT N + 1 slot is called the second real PUSCH transmission.

Abstract

The embodiment of the invention discloses a method and device for processing physical channel transmission, equipment and a storage medium, and the method for processing the physical channel transmission comprises the steps: obtaining the remaining number of times of real physical channel transmission, if the remaining number of times is two, judging whether TCI states corresponding to the two times of real physical channel transmission are the same or not, and if the remaining number of times is two, judging whether TCI states corresponding to the two times of real physical channel transmission are the same or not; and if the TCI state corresponding to the secondary real physical channel transmission is the same, enabling another TCI state configured at a high level to correspond to the second real physical channel transmission in the secondary real physical channel transmission. According to the technical scheme provided by the embodiment of the invention, the transmission facing only one TRP can be avoided, so that the gain based on the transmission of the two TRPs can be obtained.

Description

Technical field [0001] The present invention relates to the field of communication technologies, and more particularly to methods, apparatus, base station apparatus, user equipment, and storage medium for processing physical channel transmission. Background technique [0002] In order to enhance the reliability and robustness of wireless transmission, 5G NR (New Radio) introduces multiple transmit receiving points (Multiple Transmission Reception Point, referred to as "Multi-TRP"), and TRP is empty with the user equipment. In Multi-TRP transmission scenarios, multiple TRPs can serve simultaneously in one user equipment and perform data transmission. [0003] Multi-TRP transmission can include multi-DCI (Multi-DCI Based, where DCI is transmitted and based on downlink control information) transmission and SINGLE-DCI (Single-DCIBased) transmission. [0004] In the case of Multi-DCI based transmission, the two base stations can be used as a TRP, and the interaction between them is no...
