Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method for transmitting a synchronization signal block, a network device, and a user equipment.
Background
Before the user equipment communicates with the network equipment, the user equipment needs to perform cell search, find a cell to which the user equipment belongs, synchronize with the cell, and receive and decode necessary information for communication and normal operation with the cell. Specifically, the ue obtains downlink synchronization and Physical layer Cell identity information (Cell ID) of a Cell by detecting a Primary Synchronized Signal (PSS) and a Secondary Synchronized Signal (SSS) at a specific location, and then obtains necessary Cell system information by receiving a Physical Broadcast Channel (PBCH) Signal.
In a Long Term Evolution (Long Term Evolution, hereinafter abbreviated as LTE) system, in order to assist cell search, each downlink component carrier has two special signals PSS and SSS, where the PSS is obtained by spreading a Zadoff-Chu sequence with a length of 63 by 50 at both ends and finally mapping the Zadoff-Chu sequence to the middle 6 Physical Resource Blocks (PRB). Like PSS, SSS is also 6 PRBs occupying the middle. PBCH is used to transmit limited necessary cell system information, and since the user equipment may not know the bandwidth of the downlink cell when receiving the PBCH, the PBCH transmission is limited to the middle 72 subcarriers regardless of the cell bandwidth. That is, the PSS/SSS and PBCH occupy the same number of resource blocks in the frequency domain and are mapped to the same frequency domain location. In the time domain direction, in FDD mode, PSS is transmitted in the last symbol (symbol) of the first slot (slot) of the 0 th and 5 th subframes, SSS is transmitted in the same slot in the position next to the last symbol, i.e. SSS is located on the symbol before PSS; in TDD mode, PSS is transmitted on the third symbols of the 1 st and 6 th subframes, i.e. in the DwPTS domain, and SSS is transmitted on the last symbols of the 0 th and fifth subframes, i.e. three symbol positions before the PSS. And for PBCH, either FDD or TDD, the transmission is on the first 4 symbols of the 2 nd slot of the 0 th subframe. Thus, in FDD, the PBCH immediately follows the PSS and SSS of the 0 th subframe.
In the design of a New Radio (NR) system, NR-PSS and NR-SSS are used for assisting cell search, and NR-PBCH is used for transmitting necessary system information. The length of the sequences of the NR-PSS and the NR-SSS is 127, the occupied frequency domain resources are 12 NR-PRBs, and the bandwidth of the NR-PBCH is 288 subcarriers, that is, 288/12 ═ 24 PRB, so the number of resource blocks occupied by the NR-PSS/NR-SSS in the frequency domain is different from that of the NR-PBCH. The mapping and design of the synchronization signal of the existing LTE can not effectively support the cell search in the NR system, and the LTE system lacks forward compatibility and optimization capability in the aspect of subsequent access systems of user equipment.

Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
The embodiment of the invention provides a transmission method of a synchronous signal block, which is applied to a network device side, wherein the synchronous signal block comprises the following steps: NR-PSS, NR-SSS and NR-PBCH signals. As shown in fig. 1, the transmission method specifically includes the following steps:
step 101: on the first time domain resources, the NR-PBCH signal is transmitted through the first frequency domain resources.
Step 102: on the second time domain resources, the NR-PSS and the NR-SSS are transmitted through the second frequency domain resources, and physical signals and/or physical channels having the same beam characteristics as the synchronization signal blocks are transmitted through the third frequency domain resources.
The network device refers to a network side device, and generally has configuration and access capabilities, for example, a base station, an access point, and other devices. The first frequency domain resources include second frequency domain resources and third frequency domain resources, and the physical signals and/or physical channels have the same beam characteristics as the synchronization signal block. For digital beams, the transmitter can transmit beams in different directions in different frequency domains on the same time domain symbol, while for analog beams, the transmitter can transmit beams in only one direction on the same time domain symbol, and thus, the physical signals and/or physical channels transmitted by the synchronization signal block and the synchronization signal block have the same beam characteristics. The network device determines a physical signal and/or a physical channel to be sent to the user equipment according to information such as a cell type and transmission parameter configuration of a serving cell served by the network device, wherein when the information such as the cell type and the transmission parameter configuration of the serving cell is different, the physical signal and/or the physical channel sent by the network device through the third frequency domain resource is different.
It should be noted that, the above steps 101 to 102 are only one transmission timing sequence of the NR-PSS, NR-SSS, NR-PBCH signals and physical signals and/or physical channels in the present invention, and in other embodiments of the present invention, other transmission timing sequences may also be adopted to transmit the NR-PSS, NR-SSS, NR-PBCH signals and physical signals and/or physical channels.
Specifically, the synchronization signal block comprises 4 consecutive time domain symbols, wherein a first time domain resource occupied by the NR-PBCH signal comprises 2 time domain symbols, a second time domain resource occupied by the NR-PSS and the NR-SSS comprises 2 time domain symbols, and the NR-PSS and the NR-SSS respectively occupy 1 time domain symbol. The bandwidth of the first frequency domain resource occupied by the NR-PBCH signal is 4.32M, 288 subcarriers are occupied totally, and the bandwidth of the second frequency domain resource occupied by the NR-PSS and the NR-SSS is 2.16M, and 127 subcarriers are occupied respectively. That is to say, in 2 time domain symbols occupied by the NR-PSS and the NR-SSS, frequency domain resources are still idle, and these idle frequency domain resources are third frequency domain resources.
Further, the physical signal comprises at least one of: a reference signal for beam management and mobility measurement, a demodulation reference signal of a physical broadcast channel, and a signal indicating beam index information; the physical channel comprises at least one of: the system comprises a group common downlink control channel, a paging channel, channels carrying other broadcast information and a default downlink control channel.
Wherein, as shown in fig. 2, the network device transmits the NR-PBCH signal through the first frequency domain resource on the first time domain resource, transmits the NR-PSS and NR-SSS through the second frequency domain resource on the second time domain resource, and transmits additional physical signals and/or physical channels through the third frequency domain resource.
When the network device sends the reference signal for beam management and mobility measurement through the third frequency domain resource, the user equipment reports the relevant information to the network device according to the received reference signal characteristics to assist the network device in beam management and mobility management.
If the network device sends the demodulation reference signal of the physical broadcast channel through the third frequency domain resource, as shown in fig. 3, the network device sends the demodulation reference signal DMRS of the NR-PBCH through a specific subcarrier Subcarriers in the physical resource block NR-PRB of the third frequency domain resource, which may assist in coherent demodulation of the PBCH channel.
If the network device sends the signal indicating the beam index information through the third frequency domain resource, the network device may notify the user device of the received beam index information, so that the user device skips a process of blindly detecting other beams, directly receives the indicated beam, and reduces the receiving complexity of the user device.
Or, when the network device sends the Group Common downlink control channel Group Common PDCCH through the third frequency domain resource, the Group Common control information such as the slot structure is sent, and the user equipment obtains information such as which symbols in the slot configuration are used for uplink/downlink transmission, thereby reducing the blind detection complexity.
And when the network equipment sends a paging channel through the third frequency domain resource, wherein the paging channel carries a paging signal of the network equipment, so that the user equipment can quickly access the network equipment.
When the network device sends a channel carrying other broadcast information through the third frequency domain resource, the other broadcast information may include On-demand system information (On-demand SI) and others, so that the user device receives the required system information.
When the network device sends a Default downlink control channel (Default NR-PDCCH) through a third frequency domain resource, namely the PDCCH which is initially accessed and configured according to a preset value or Default configuration, the user equipment performs detection according to the preset value or Default configuration, and the blind detection complexity is reduced.
Further, since there are various combination sequences of time domain positions between the NR-PSS, NR-SSS and physical broadcast channel signals in the synchronization signal block, the network device may implicitly carry additional information by configuring different position relationships. In particular, assuming that the frequency domain locations between the NR-PSS, NR-SSS and the physical broadcast channel signals are relatively fixed, the network device may also: and hiding the carried information through the first position relation between the first time domain resource and the second time domain resource. The position information of the synchronization signal blocks corresponding to different implicit information is different, and the different position information means that the time domain position information allocated for NR-PSS, NR-SSS and NR-PBCH signals is different. The mapping relation between the position information of the synchronous signal block and the implicit information is configured in advance, and the implicit information which needs to be carried is determined, so that the position information of the synchronous signal block can be determined.
The step of sending the NR-PSS and NR-SSS on the second time domain resource through the second frequency domain resource includes: transmitting the NR-PSS through the second frequency domain resource on the third time domain resource; and transmitting the NR-SSS through the second frequency domain resource on the fourth time domain resource.
Further, the second time domain resource includes a third time domain resource and a fourth time domain resource, and the step of transmitting the NR-PSS and the NR-SSS through the second frequency domain resource on the second time domain resource includes: transmitting the NR-PSS through the second frequency domain resource on the third time domain resource; and transmitting the NR-SSS through the second frequency domain resource on the fourth time domain resource. The step of hiding the carried information through the first position relation between the first time domain resource and the second time domain resource comprises the following steps: and hiding the carried information through the first position relation among the first time domain resource, the third time domain resource and the fourth time domain resource.
Furthermore, the frequency domain bandwidth occupied by the NR-PSS and the NR-SSS is smaller than that occupied by the NR-PBCH signal, so that the frequency domain position relations of the NR-PSS, the NR-SSS and the NR-PBCH signal have various combination forms, and the information can be hidden and carried through different frequency domain position relations. In particular, assuming that the time domain locations between the NR-PSS, NR-SSS and NR-PBCH signals are relatively fixed, the network device may also: and hiding the carried information through a second position relation between the first frequency domain resource and the second frequency domain resource. The position information of the synchronization signal blocks corresponding to different implicit information is different, and the different position information means that the frequency domain position information allocated for NR-PSS, NR-SSS and NR-PBCH signals is different. The mapping relation between the frequency domain information of the synchronization signal block and the implicit information is configured in advance, and the frequency domain position information of the synchronization signal block can be determined by determining the implicit information which needs to be carried.
Further, the second frequency-domain resource includes a first frequency-domain sub-band and a second frequency-domain sub-band, and the step of transmitting the NR-PSS and the NR-SSS through the second frequency-domain resource on the second time-domain resource includes: transmitting the NR-PSS through the first frequency domain sub-band on the second time domain resource; and transmitting the NR-SSS over a second frequency-domain subband on a second time-domain resource. The step of hiding the carried information through the second position relationship between the first frequency domain resource and the second frequency domain resource comprises the following steps: and hiding the carried information through the first frequency domain resources and the second position relation among the first frequency domain sub-band and the second frequency domain sub-band.
Besides the time domain position relation of the synchronous signal blocks, the frequency domain position relation among the NR-PSS, the NR-SSS and the NR-PBCH signals can be further considered to conceal the carried information. Specifically, the network device may implicitly indicate the carried information in a combined manner through a first location relationship between the first time domain resource and the second time domain resource and a second location relationship between the first frequency domain resource and the second frequency domain resource.
Specifically, as shown in fig. 4, the second time domain resource includes a third time domain resource and a fourth time domain resource, the second frequency domain resource includes a first frequency domain sub-band and a second frequency domain sub-band, and the step of transmitting the NR-PSS and the NR-SSS through the second frequency domain resource on the second time domain resource includes: transmitting the NR-PSS through the first frequency domain sub-band on the third time domain resource; and, on a fourth time domain resource, transmitting the NR-SSS over the second frequency domain subband; the step of jointly hiding the carried information through a first position relation between the first time domain resource and the second time domain resource and a second position relation between the first frequency domain resource and the second frequency domain resource comprises the following steps of: and jointly hiding the carried information through the first position relation among the first time domain resource, the third time domain resource and the fourth time domain resource and the second position relation among the first frequency domain resource, the first frequency domain sub-band and the second frequency domain sub-band. Meanwhile, the time domain position relation and the frequency domain position relation of the synchronous signal blocks are considered, and the position relation combination forms among the NR-PSS, the NR-SSS and the NR-PBCH signals are increased, so that the network equipment can conceal information carrying more bits. For example, 2 positions of NR-PSS, NR-SSS and NR-PBCH signals are involved, so that 1-bit information can be implicitly carried; if there are 4 position relations, it can be hidden to carry 2 bits of information.
In the above, the information is implicitly carried through the position relationship among the NR-PSS, NR-SSS, and NR-PBCH signals, and specifically, when the time domain positions among the NR-PSS, NR-SSS, and NR-PBCH signals have various combination sequences and fixed frequency domain positions, the implicit way to carry additional information is specifically: and carrying information is hidden through the transformation of the first position relation between the first time domain resource and the second time domain resource in the synchronous signal burst set period. That is, within one synchronization signal burst set period, the time domain positions between the NR-PSS, NR-SSS, and NR-PBCH signals are not fixed, and the network device may configure the time domain positions between the NR-PSS, NR-SSS, and NR-PBCH signals differently according to the implicit information that needs to be sent. Or, when the time domain position among the NR-PSS, NR-SSS, and NR-PBCH signals is fixed and there are various combination forms of frequency domain positions, the method of implicitly carrying extra information is specifically: and carrying information is hidden through the transformation of a second position relation between the first frequency domain resource and the second frequency domain resource in a synchronization signal burst set period. That is, the frequency domain positions between the NR-PSS, NR-SSS, and NR-PBCH signals are not fixed within one synchronization signal burst set period, and the network device may configure the frequency domain positions between the NR-PSS, NR-SSS, and NR-PBCH signals differently according to implicit information that needs to be transmitted. When various combination forms exist in the time domain position and the frequency domain position among the NR-PSS, the NR-SSS and the NR-PBCH signals, the method for implicitly carrying the extra information specifically comprises the following steps: and carrying information is hidden through the transformation of the first position relation between the first time domain resource and the second position relation among the first frequency domain resource, the first frequency domain sub-band and the second frequency domain sub-band in the synchronous signal burst set period. That is, within one synchronization signal burst set period, the time domain position and the frequency domain position between the NR-PSS, NR-SSS, and NR-PBCH signals are not fixed, and the network device may configure the time domain position and the frequency domain position between the NR-PSS, NR-SSS, and NR-PBCH signals differently according to the implicit information that needs to be transmitted.
Specifically, through the first position relationship between the first time domain resource and the second time domain resource, the step of implicitly displaying the carried information includes: through a first position relationship between the first time domain resource and the second time domain resource, the method for implicitly carrying system information specifically comprises the following steps: and hiding the carried system information through the first position relation among the first time domain resource, the third time domain resource and the fourth time domain resource. Through the second position relationship between the first frequency domain resource and the second frequency domain resource, the step of hiding the carried information specifically comprises the following steps: through a second position relationship between the first frequency domain resource and the second frequency domain resource, the carrying of system information is hidden, specifically: and hiding the carried system information through the first frequency domain resources and the second position relation among the first frequency domain sub-band and the second frequency domain sub-band. The step of jointly hiding the carried information through a first position relation between the first time domain resource and the second time domain resource and a second position relation between the first frequency domain resource and the second frequency domain resource comprises the following steps of: through a first position relationship between the first time domain resource and the second time domain resource and a second position relationship between the first frequency domain resource and the second frequency domain resource, the combined implicit indication of the carried system information specifically comprises the following steps: and jointly hiding the carried system information through the first position relation among the first time domain resource, the third time domain resource and the fourth time domain resource and the second position relation among the first frequency domain resource, the first frequency domain sub-band and the second frequency domain sub-band. The system information carried by the implicit indication may be key system information, for example, system information identifying an FDD system or a TDD system, or system information identifying an SA system or an NSA system.
It was explained above that the frequency domain bandwidth of the synchronization signal block, i.e. the bandwidth occupied by the NR-PBCH, is equal to the system bandwidth. In the following, a scenario will be described in which the bandwidth of the first frequency domain resource occupied by the NR-PBCH is smaller than the bandwidth of the system frequency domain resource, and in this scenario, as shown in fig. 5, the synchronization signal block further includes frequency domain resources other than the first frequency domain resource in the system frequency domain resource, and this portion of the frequency domain resources is referred to as fourth frequency domain resources, and the network device may further transmit the physical signal and/or physical channel through the fourth frequency domain resource in addition to transmitting the additional physical signal and/or physical channel through the third frequency domain resource. Wherein the physical signal comprises at least one of: a reference signal for beam management and mobility measurement, a demodulation reference signal of a physical broadcast channel, and a signal indicating beam index information; the physical channel comprises at least one of: the system comprises a group common downlink control channel, a paging channel, channels carrying other broadcast information and a default downlink control channel.
In the transmission method of the synchronization signal block in the embodiment of the invention, the network equipment transmits the physical signals and/or physical channels with the same beam characteristics as the synchronization signal block by using the frequency domain resources except the frequency domain resources corresponding to the NR-PSS, the NR-SSS and the NR-PBCH in the synchronization signal block, so that the resource utilization rate of the synchronization signal block can be improved, and the user equipment can optimize the access network and provide an optimization strategy for the network to regulate and control initial access according to the acquired physical signals and/or physical channels.

In addition, the network device may also jointly conceal the carried information according to a first position relationship between the first time domain resource and the second time domain resource and a second position relationship between the first frequency domain resource and the second frequency domain resource. Specifically, the second time domain resource includes a third time domain resource and a fourth time domain resource, and the second frequency domain resource includes a first frequency domain subband and a second frequency domain subband.
