  • Codebook-based uplink transmission may also be referred to as codebook transmission.
  • Codebook-based uplink transmission is a multi-antenna transmission technology that determines the TPMI of uplink transmission based on a fixed codebook.
  • the process of codebook-based uplink transmission in the NR system is as follows:
  • the UE sends the SRS to the base station on the SRS resource set obtained through the channel state information (Channel State Information, CSI) used for codebook-based uplink transmission.
  • CSI Channel State Information
  • the base station performs uplink channel detection according to the SRS sent by the UE, performs resource scheduling on the UE, and determines the SRS resource corresponding to the uplink transmission based on the codebook, the number of layers of the uplink transmission and the precoding matrix. Further, the UE can determine the modulation and coding strategy (Modulation and Coding Scheme, MCS) for uplink transmission according to the precoding matrix and channel information, and then the base station allocates PUSCH resources and assigns the corresponding MCS, TPMI, layer indicator (Layer Indicator, LI). ) and an SRS resource indication (Sounding Reference Signal Resource Indicator, SRI) are notified to the UE.
  • MCS Modulation and Coding Scheme
  • the UE modulates and encodes the data according to the MCS indicated by the base station, and uses SRI, TPMI and LI to determine the precoding matrix and the number of transmission layers used for data transmission, and then precodes and transmits the data.

  • a maximum of two SRS resources can be configured in the SRS resource set, and the two SRS resources include The same number of SRS antenna ports. Since the MTRP-based PUSCH enhancement was introduced in R17, starting from R17, the NR system allows the base station to configure at most two SRS resource sets for the UE for CSI acquisition based on codebook-based uplink transmission. Whether the number of resources that can be included in the two SRS resource sets is the same is limited.
  • the base station indicates the SRS resource corresponding to the PUSCH to the UE through the SRI field in the DCI to assist the UE to determine the antenna and analog beamforming used for PUSCH transmission according to the SRS resource selected by the base station. Since the number of SRS resources configured by the base station for different uplink transmissions may be different, determining the number of bits corresponding to the SRI based on the uplink transmission can reduce the overhead of the SRI. Therefore, the size of the SRI information used to indicate the SRS resource corresponding to the PUSCH in the uplink scheduling information depends on the number of SRS resources configured for the uplink transmission corresponding to the PUSCH. When the base station configures only one SRS resource for one uplink transmission of the UE, the PUSCH under the uplink transmission corresponds to the SRS resource, and the SRI information field may not exist in the uplink scheduling information.
  • the base station can configure a SRS resource set with a purpose of "codebook" for the terminal, which includes at most two SRS resources, and all SRS resources have the same number of antenna ports.
  • the codebook subset that the base station can configure for the terminal depends on the coherent transmission capability of the terminal.
  • the R15 protocol stipulates that the coherent transmission capability is a non-coherent terminal (NC-UE) and a partially coherent terminal (PC-UE) only allowed to configure and use a part of the codebook subset. Combined with the power control rules of PUSCH, these terminals cannot reach full power when performing low-rank transmission. In an actual system, the signal-to-noise ratio of the terminal located at the edge of the cell is usually relatively low.
  • the base station In order to ensure the signal quality, the base station often schedules the terminal to perform low-rank transmission and transmit with the largest possible transmit power. The inability to transmit at full power will affect the performance of the terminal in the low signal-to-noise ratio area, thereby affecting the cell coverage.
  • NC-UE and PC-UE to achieve full power transmission at low rank is due to codebook subset limitation and PUSCH power control rules.
  • the full power transmission of PUSCH can be achieved by enhancing the codebook subset restriction or enhancing the PUSCH power control rule.
  • R16 allows the base station to configure a specific full power transmission mode for the terminal, called Mode 0 (Mode0) full power transmission mode.
  • Mode 0 full power transmission is no longer applicable if one or more of the terminal's PAs cannot transmit at full power.
  • R16 introduces two full power transmission modes, Mode 1 (Mode1) and Mode 2 (Mode2).
  • Mode 2 adopts the same codebook subset configuration restriction as R15. Through the new SRS resource configuration method and new PUSCH power control rules, incoherent or partially coherent terminals are allowed to use the PA using antenna virtualization or full power transmission A specific precoding matrix achieves full power transmission of PUSCH.

Abstract

Des modes de réalisation de la présente demande concernent un procédé de communication sans fil, un équipement terminal et un dispositif réseau. Le procédé comprend : la réception d'informations d'indication pour indiquer la transmission de PUSCH, un PUSCH étant transmis de manière répétée sur la base d'une première ressource SRS dans un premier ensemble de ressources SRS et d'une seconde ressource SRS dans un second ensemble de ressources SRS; le premier ensemble de ressources SRS et le second ensemble de ressources SRS étant tous deux utilisés pour une transmission basée sur un livre de codes; lorsque le nombre de ports de la première ressource SRS est différent du nombre de ports de la seconde ressource SRS, le nombre maximal de couches du PUSCH ne dépasse pas la valeur minimale du nombre de ports de la première ressource SRS et du nombre de ports de la seconde ressource SRS. Selon la solution proposée dans la présente demande, l'équipement terminal peut transmettre le PUSCH de manière répétée. De plus, lorsque la transmission répétée en liaison montante d'un multi-TRP est réalisée, le nombre de couches sélectionnées par l'équipement terminal peut être supporté par l'équipement terminal, ce qui permet d'assurer la qualité de communication.
