Network side equipment 102 can be communicated with multiple terminal devices (such as terminal device 116 and terminal device 122).So And, it will be understood that network side equipment 102 can lead to any number of terminal device for being similar to terminal device 116 or 122 Letter.

As shown in Figure 1, terminal device 116 is communicated with antenna 112 and 114, wherein antenna 112 and 114 passes through forward link 116 send information to terminal device 116, and receive information from terminal device 116 by reverse link 120.In addition, terminal device 122 communicate with antenna 104 and 106, and wherein antenna 104 and 106 sends information to terminal device 122 by forward link 124, and Information is received from terminal device 122 by reverse link 126.

For example, in frequency division duplex (frequency division duplex, FDD) system, for example, forward link 116 It is available with different frequency bands used in reverse link 120, forward link 124 it is available with used in reverse link 126 not Same frequency band.

For another example in time division duplex (time division duplex, TDD) system and full duplex (full duplex) In system, common frequency band is can be used in forward link 116 and reverse link 120, and forward link 124 and reverse link 126 can be used Common frequency band.

The every group of antenna and/or region that are designed to communication are known as the sector of network side equipment 102.For example, can be by day Line group is designed as and the terminal equipment in communication in the sector of 102 overlay area of network side equipment.Before network side equipment 102 passes through During being communicated respectively with terminal device 116 and 122 to link 116 and 124, the transmitting antenna of network side equipment 102 The signal-to-noise ratio of forward link 116 and 124 can be improved using beam forming.In addition, with network side equipment by individual antenna to The mode that its all terminal device sends signal is compared, and utilizes beam forming to associated coverage in network side equipment 102 When the terminal device 116 and 122 of middle random dispersion sends signal, the mobile device in neighboring community will receive less interference.

As it was noted above, when terminal device need to access network (such as terminal device be switched on after or terminal device and net When the connection of network equipment needs to reconnect after disconnecting), terminal device can complete down-going synchronous by search SSB first, then System message is obtained, subsequent terminal device can initiate random access mistake by sending random access leader sequence (preamble) Journey (random access procedure) and cell establish connection and obtain uplink synchronous.

Currently, under each subcarrier spacings, a carrier frequency range corresponds to a SSB pattern, and network is set in NR It is standby SSB to be sent according to the corresponding SSB pattern of carrier frequency range.In NR, the mapping of SSB will receive uplink-downlink configuration letter The influence of breath, SSB only can be in semi-static (semi-static) downlink (down link, DL) resources and unknown (unknown) It is transmitted in the downlink symbol of resource.One SSB pattern of an existing carrier frequency range may be with the uplink and downlink that configures in NR There is conflict in resource, lead to SSB that the network equipment is sent in the SSB detection window on the carrier frequency range according to the SSB pattern Less, the covering demand being unable to satisfy on the carrier frequency range of number, or the maximum that SSB is transmitted in SSB detection window is not achieved Number causes the prior art to need just to be able to achieve the transmission of maximum number SSB by mostly wheel transmission, causes access delay longer, from And affect the efficiency of terminal equipment access network.

In view of the above problems, a kind of method that the embodiment of the present application proposes communication, in the embodiment of the present application, a carrier frequency Frequency range can correspond to multiple SSB patterns, for example, corresponding two SSB patterns, the network equipment can be flexible according to the difference of scene A SSB pattern is determined from multiple SSB patterns, and then the SSB pattern that the network equipment can be determined according to it sends SSB, and The SSB sent in a SSB detection window can achieve maximum number.Therefore, the embodiment of the present application can reduce access delay, So as to promote the efficiency of terminal equipment access network.

In other words, multiple SSB patterns can be configured for a carrier frequency range in the embodiment of the present application, in a carrier frequency frequency For the uplink and downlink resource configured in the SSB pattern and NR of section in the presence of when conflicting, the embodiment of the present application can be using this load Another of frequent section does not send SSB with the SSB pattern of the uplink and downlink resource contention of configuration.And then the embodiment of the present application can drop Generation that is low or avoiding above-mentioned conflict situations.Therefore, the SSB that the embodiment of the present application is sent in a SSB detection window can reach To maximum number, and then access delay can be reduced, to promote the efficiency of terminal equipment access network.

Wherein, for the subcarrier spacing of 30kHz, in a SSB detection window, the time domain of SSB is configured just like Fig. 3 and figure The corresponding SSB pattern of two different mapping patterns in 4, i.e. Case B and the corresponding SSB pattern of Case C.Wherein, Case B Corresponding SSB pattern (hereinafter referred to as mapping pattern 1 or pattern 1 for ease of description) is mainly used for NR carrier wave and LTE carrier wave is total The scene deposited, the CRS that can avoid 15kHz on LTE carrier wave are disturbed.The corresponding SSB pattern of Case C is (following for ease of description Referred to as mapping pattern 2 or pattern 2) it is mainly used for that other outer scenes coexist, mainly consider the SSB mapping pattern of 30kHz With the compatibling problem of the SSB mapping pattern of 15kHz.

Since the mapping of SSB will receive the influence of uplink-downlink configuration information, SSB only can be in semi-static (semi- Static it) is transmitted in the downlink symbol in DL and unknown (unknown) resource.Therefore, below to the embodiment of the present application Semi-static uplink-downlink configuration is described.

In terms of semi-static uplink-downlink configuration, NR supports extremely flexible configuration method.The uplink-downlink configuration resource packet of NR Include downlink (DL) resource, uplink (UL) resource and unknown (unknown) resource.Semi-static uplink-downlink configuration, can be by small Specific (cell-specific) RRC signaling in area or system information are allocated to UE, can also be specific by UE (UE-specific) RRC signaling is configured, and the embodiment of the present application is not limited to this.For each subcarrier spacings (for example, 15kHz, 30kHz, 120kHz, 240kHz), semi-static uplink and downlink (semi-static UL/DL) the configuration period supports 0.125ms, 0.25ms, 0.5ms, 1ms, 2ms, 5ms and 10ms.In addition, 30kHz or more subcarrier spacing (>=30KHz SCS), supports 2.5ms Semi-static UL/DL configures the period.60kHz or more subcarrier spacing (>=60KHz SCS) supports 1.25ms semi- Static UL/DL configures the period.For 120kHz subcarrier spacing, the semi-static UL/DL of 0.625ms is supported to configure the period.

For example, showing the semi-static uplink-downlink configuration period in Fig. 5 is 5ms, time slot is that the semi-static uplink and downlink of 0.5ms is matched The pattern set.Wherein, the resource distribution in the pattern is downlink resource-unknown resources-ascending resource (DL-unknown-UL), The network equipment can pass through the pattern of parameter (x1, x2, y1, y2) the instruction terminal equipment uplink-downlink configuration.Wherein, under x1 expression Slot number of row resource, x2 indicate the symbol numbers of downlink resource, and y2 indicates the symbolic number of ascending resource, and y1 indicates uplink money The slot number in source.As shown in figure 5, it can be the value of 7, y1 that the value that x1 value can be 3, x2, which can be the value of 7, y2, It can be 3.Wherein, unknown (unkow) resource of resource representation within the configuration period among downlink resource and ascending resource.

It should be understood that uplink-downlink configuration pattern shown in fig. 5 is only illustrative, period of uplink-downlink configuration and time slot it is big It is small to change according to the actual situation, for example, the configuration period can be 2.5ms, the time slot etc. of corresponding 5 0.5ms, the application reality Example is applied to be not limited to this.

For example, by taking the period of 5 time slots as an example, more typical some uplink-downlink configuration options when actual product is realized It may include: DDDSU, wherein each capitalization in DDDSU indicates a time slot.Wherein, the time slot that D is indicated is downlink Resource, the time slot that S is indicated are special time slot, and the time slot that U is indicated is ascending resource.It may include being provided as downlink in special time slot Symbol, unknown symbols and the symbol as downlink resource in source.Uplink and downlink symbol in one of typical special time slot is matched Setting includes: ddddddddddxxuu.Wherein, each lowercase indicates that a symbol, the symbol that alphabetical d is indicated are downlink money Source, the symbol that x is indicated are unknown symbols, and the symbol that u is indicated is ascending resource.In two symbols that the resource type is x extremely A rare symbol is used for the protection interval (gap) between uplink and downlink resource.

For corresponding SSB mapping pattern 2 (the corresponding SSB pattern of Case C) mentioned above, in L=8, in some allusion quotations Under type uplink-downlink configuration, the uplink-downlink configuration of 5 time slots as mentioned above is DDDSU, and wherein S is ddddddddddxxuu When, it cannot achieve the SSB that maximum number is sent in the time window of 5ms.Specifically, as shown in figure 4, the 5ms of mapping pattern 2 Time window in, SSB is distributed in preceding 4 time slots.And uplink-downlink configuration according to figure 5, it can be deduced that before shown in fig. 6 Pattern in 4 time slots.Specifically, as shown in fig. 6,8 candidate SSB are mapped in 4 time slots according to mapping pattern 2, and Since the resource type of the 10th and 11 symbols in the 4th time slot (time slot that resource type is S) of uplink-downlink configuration is x, again Since two resource types are used for the protection interval (gap) between uplink and downlink resource at least one symbol in the symbol of x, because This, which is that the symbol of x can not be completely used for downlink transfer, and therefore, the uplink-downlink configuration and mapping pattern 2 are most The resource contention of the latter SSB causes the last one SSB in mapping pattern 2 that can be struck off, under this uplink-downlink configuration, such as Fruit 2 transmission SSB from the flat, will lead in time detection window (5ms) that at most there is only 7 SSB.So as to cause subcarrier Between be divided under 30kHz resource SSB covering be deteriorated, influence the efficiency of terminal equipment access network.

The embodiment of the present application is avoided being sent SSB using pattern 2, but uses figure in the case where above-mentioned uplink-downlink configuration Sample 1 sends SBB, due to using pattern 1 to send SSB there is no above-mentioned conflict, the embodiment of the present application can guarantee one The SSB maximum number transmitted in a time window is 8.Therefore, the embodiment of the present application is able to ascend the access network effect of terminal device Rate.
