According to one or more embodiments, the spatial structure of NR synchronization signal may include the week of synchronization signal burst 310 Phase property transmission, wherein each synchronization signal burst 310 may include one or more synchronization signal blocks 312.Synchronization signal burst The period 314 and duration 316 of collection 318 and/or synchronization signal burst 310 can be configured by higher level signaling, or can be with It is determined in advance by defined in NR standard.In one or more embodiments, higher level may include higher than physical layer Layer, for example, media access control (MAC) layer, radio link control (RLC) layer, Packet Data Convergence Protocol (PDCP) Layer, radio resource control (RRC) layer or Non-Access Stratum (NAS) etc., although the range of claimed theme is in this respect not It is limited.

In one or more embodiments, can be sent in synchronization signal (SS) block 312 PSS114, SSS 116 and/ Or Physical Broadcast Channel (PBCH), and the multiplexing of other signals is not excluded in SS block 312.SS burst 310 may include one Or multiple SS blocks 312, wherein the number of SS block 312 can define the duration of SS burst 310.SS burst collection 318 can wrap Include one or more SS bursts 310.It should be noted that the synchronization structure in NR standard can support various situations, including support to utilize The multi-beam of beam scanning in synchronization signal operates, and supports to transmit using the repeated simple beam spread over, and/or The transmission for supporting the expense of the synchronization signal in simple beam transmission to reduce, although claimed theme does not limit in this respect System.As will be discussed in further detail, transmission can be for SS burst 310 using same beams, SS burst 310 it Between use different beams, and SS burst collection 318 between using rule beam pattern omnidirectional or quasi- omni-direction transmissions, or Between the SS block 312 in SS burst 310 using different (narrow or wide) wave beams, between SS burst 310 using different beams, with And using the directional transmissions of the beam pattern of rule between SS burst collection 318, although the range of claimed theme is at this Aspect is with no restrictions.

Referring now to Figure 4, by synchronization signal block is used in multi-beam mode of the discussion according to one or more embodiments The schematic diagram of Wave beam forming distribution.In order to support the scene of multi-beam transmission, different transmission Wave beam formings can be by gNB 110 The synchronization signal block 312 being used for transmission in the synchronization signal burst 310 in a synchronization signal burst collection 318.Send wave beam shape It can be on synchronization signal burst collection 318 at pattern identical.

Fig. 4 shows the Wave beam forming distribution of the different synchronization signal blocks 312 in synchronization signal burst collection 318, wherein needle Different Wave beam forming patterns 410 is applied to the different synchronization signals burst 310 in identical synchronization signal burst collection 318.To the greatest extent Another synchronization signal burst collection 318 is not shown in pipe, it is believed that gNB 110 can believe using with current beam Synchronization Number burst collection 318 identical Wave beam forming patterns.

When gNB 110 support wave beam number it is bigger when, can be related to synchronization signal burst collection 318 in multiple synchronizations Burst 310.In one example, synchronization signal burst collection 318 may include only one synchronization signal burst 310, such In example, the number of the synchronization signal block 312 in synchronization signal burst 310 can be variable number, to utilize different wave beams It forms configuration and supports gNB110.

Referring now to Figure 5, by discussion according to the selection of the synchronization signal block in the synchronization burst of one or more embodiments Schematic diagram.In another embodiment, gNB 110 can send the son of the synchronization signal block 312 in synchronization signal burst 310 Collection.In such embodiments, can happen suddenly 310 or one or more synchronization signal burst collection across multiple synchronization signal blocks The 318 selected synchronization signal patterns of maintenance.It In a particular embodiment, as shown in figure 5, can be in synchronization burst 310 Use only one synchronization signal 312.Synchronization signal pattern can change for different gNB 110, to help to realize synchronization signal The AF panel in the time domain of block 312 or for reducing expense.It can be transmitted same by being indicated in broadcast control message Actual number and its pattern of signal are walked to help to reduce expense, wherein bitmap can be used with signal and send the Broadcasting Control Message, although the range of claimed theme is in this respect with no restrictions.

In another embodiment, referring again to FIGS. 3, gNB 110 can automatically turn on or close synchronous transmission of signal, with Carry out overhead control or interference management.In other words, due to various reasons, it may be considered that for such as PSS 114, SSS 116 or Unlatching/shutdown mechanism of the synchronous transmission of signal of entire synchronization signal block 312, so that gNB 110 efficiently controls expense, control Interference etc..In such an arrangement, UE 112 can be assumed that synchronization signal 312 may be not present, so that UE 112 can be with It executes signal and there is detection.It can realize that signal has detection by threshold test or other means in UE 112, for example, if In the presence of the auxiliary synchronization channel (S-SCH) based on the forward error recovery (FEC) using cyclic redundancy check (CRC), then can lead to It crosses and blind decoding and check (CRC) is carried out to S-SCH to execute detection.On the other hand, it is assumed that the detection of PSS 114 is for UE 112 It says and executes complex, then it is contemplated that the constant transmissions of PSS 114, while SSS can be sent by opportunism mode 116 or other channels.Synchronization signal burst 310 include duplicate multiple times in given synchronization signal burst 310/ Exemplary frequency example.In conjunction with unlatching/shutoff operation of synchronization signal 312, the OFDM symbol grade in 310 of can happening suddenly in synchronization signal, Collect 310 grades of synchronization signal burst in 318 in synchronization signal burst or happen suddenly in synchronization signal and collects 318 grades of execution gNB110 Automatic opening/closing operation.

Be not turned on/shutoff operation and in the case where send 114 PSS always, can assume pre-determined bit for UE112 It sets, safely to accumulate multiple examples.It, can be from all gNB and/or cell or gNB and/or small especially for PSS 114 General 114 sequence of PSS of the subset or group definition in area, can also provide single frequency network (SFN) gain.For SSS 116, the detection that opportunism transmission is realized in the detection based on search space can be passed through in UE112, wherein search space can be with It is scheduled, and gNB 112 can automatically select a space to send SSS 116.Another kind realizes such chance master The method of justice transmission can be based on the above-described forward error recovery (FEC) using cyclic redundancy check (CRC), so that UE 112 need not carry out threshold test to recognize that signal exists.

Replacing for signal synchronization is used for referring now to Figure 6, will discuss in the multi-beam mode according to one or more embodiments For the schematic diagram of Wave beam forming distribution.For example, when using for Fig. 4 embodiment relatively broad beam and identical wave beam by with Distribution shown in fig. 6 can be used when sending the synchronization signal block in synchronization signal burst.In the embodiment shown in fig. 4, Identical Wave beam forming can be used to send all synchronization signal blocks 312 in synchronization signal burst, to help reality in gNB 110 The Coherent processing of existing synchronization signal burst 310.In the present embodiment, such as Wave beam forming pattern 610, Wave beam forming pattern 612, And the synchronization signal that the Wave beam forming pattern of Wave beam forming pattern 614 etc can happen suddenly in collection 318 across synchronization signal is prominent Hair 310 and it is different.The distribution of Wave beam forming pattern can be identical on synchronization signal burst collection 318, for example, to help to realize The incoherent combination of wave beam at UE 112.
