Definitions

  • the invention discussed below relates generally to wireless communication, and more particularly, to methods for synchronization block pattern design.
  • the signal-to-noise ratio received by the receiver from the transmitter is often low due to poor background environment or long communication distances.
  • time or frequency domain signal accumulation techniques are employed.
  • the transmitter repeats the transmission of a segment of the same signal, while the receiver accumulates all the repeated signals for detection, demodulation, or decoding, or accumulates the detection or demodulation results of each repeated signal segment as the final result.
  • this patent proposes a method for synchronization signal and information pattern design sent by the transmitter to enhance the success rate of detection or decoding at the receiver.
  • the method of synchronization block (SyncBlock) design including the SyncBlock content, periodicity, location in time domain, size in time domain and resource.
  • PSS/SSS/PBCH shot pattern design within a SyncBlock including the shot definition, shot size, shot location in time domain and shot content.
  • FIG. 3 illustrates another exemplary diagram of PSS, SSS and PBCH shot pattern design.
  • the SyncBlock periodicity start symbol is the SyncBlock location reference point in time domain
  • SyncBlock One or multiple SyncBlock (s) is within a SyncBlock periodicity, and each SyncBlock can be described using the method of alternative#1.
  • the one or multiple SyncBlock (s) within the same SyncBlock periodicity is transmitted by the transmitter via the same beam or different beam.
  • the one or multiple SyncBlock (s) within the same SyncBlock periodicity have the same structure and/or pattern, and have different time domain locations.
  • FIG. 1 an exemplary diagram of SyncBlock design is descripted.
  • Both SyncBlock 1 and SyncBlock 2 occurs periodically according to the SyncBlock periodicity.
  • PSS PSS, SSS or PBCH shot pattern
  • the shot content of each PSS, SSS or PBCH shot within the same SyncBlock can be the same or different.
  • the payload of the 1 st PBCH shot and 2 nd PBCH shot can be the same or different.
  • the shot pattern design in the alternative#2 can be applied for all of PSS, SSS and PBCH.
  • FIG. 2 For example, as is shown is Figure 2, an exemplary diagram of shot pattern design within a SyncBlock is descripted. There are 3 PSS shots, 4 PBCH shots and 3 SSS shots within the SyncBlock.
  • an exemplary diagram of shot pattern design within a SyncBlock is descripted.
  • PSS shots and PBCH shots occur within the same SyncBlock.
  • Combinations such as “at least one of A, B, or C, ” “one or more of A, B, or C, ” “at least one of A, B, and C, ” “one or more of A, B, and C, ” and “A, B, C, or any combination thereof” include any combination of A, B, and/or C, and may include multiples of A, multiples of B, or multiples of C.

Abstract

En raison de différents environnements d'arrière-plan, des distances de communication et des réglementations nationales/régionales, différents modèles de signal de synchronisation et d'informations doivent être proposés. Selon un aspect, la divulgation concerne un procédé de conception de bloc de synchronisation (SyncBlock), comprenant le contenu SyncBlock, la périodicité, l'emplacement dans le domaine temporel, la taille dans le domaine temporel et la ressource. Selon un autre aspect, la divulgation concerne une conception de modèle de plan PSS/SSS/PBCH dans un SyncBlock, y compris la définition du plan, la taille du plan, l'emplacement du plan dans le domaine temporel et le contenu du plan. Selon un autre aspect, la divulgation concerne un procédé de conception de modèle de plan PSS destiné à l'amélioration des performances de détection. L'objectif de la conception de modèle de plan PSS est de permettre que l'écart entre le ou les plans PSS à l'intérieur du ou des SyncBlock (s) soit différent les uns des autres. Plusieurs exemples typiques sont présentés dans la divulgation.
