Background
An NR system synchronous broadcast block set (SSB) is a set of a plurality of synchronous broadcast blocks within a certain time period, each synchronous broadcast block corresponds to a beam direction within a uniform period, and the beam direction of each synchronous broadcast block within one SSB covers the entire cell. Terminal equipment UE needs to acquire current SSB block index information from PBCH block, and complete downlink timing of an air interface can be obtained.
And after the terminal successfully detects the primary and secondary synchronization signals, the terminal starts to receive a broadcast channel, wherein the SSB index in the broadcast channel is used for indicating the SSB subcarrier offset. The NR PBCH DM RS indicates the SSB index in addition to being used for channel estimation, helping to reduce the number of PBCH bits.
The spatial signal shaping function of the intermediate node is based on controlling the propagation of electromagnetic waves in the communication channel to improve the performance of the communication system. For example, a smart hyper-surface (RIS) is a meta-surface composed of a large number of tiny elements that diffusely reflect incident signals in a controlled manner. The intelligent super surface is applied in a communication system, and the requirement of real-time reconfigurability and control is added to the communication system. Specifically, parameters such as the phase of the super surface and the like are controlled through the base station, so that the diffuse reflection incident signals are better controlled to realize the controllable propagation of electromagnetic waves in a communication channel, and the performances of the communication system in the aspects of coverage, capacity, energy efficiency and the like are improved.
Because the control such as the middle node of the intelligent super surface is an entity newly introduced into the communication system, the beam direction can be changed when the beam from the base station passes through the super surface, the super surface can realize the controllable transmission of a plurality of phase changes, a plurality of beam forming can be reflected when the existing SSB beam sent by the base station passes through the RIS unit, and the sending period and the sending pattern of the synchronous block need to be redesigned in order to facilitate the terminal to detect the intensity of the received signal and obtain the optimal beam direction.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
The application provides a method for sending and indicating a synchronization block of a wireless communication system, wherein the wireless communication system comprises network equipment, an intermediate node device and user equipment; and the service signal sent by the network equipment is reflected to the user equipment through the intermediate node device, or the service signal sent by the network equipment is directly received by the user equipment. The SSB is a set of multiple synchronous broadcast blocks within a certain time period, each synchronous broadcast block corresponds to a beam direction within a uniform period, and the beam direction of each synchronous broadcast block within one SSB covers the entire cell. The intermediate node equipment is provided with R adjusting coefficients, and any 1 basic beam of the network equipment forms R adjusting beams after passing through the intermediate node equipment; the 1 base beam and the R adjustment beams respectively correspond to 1 SSB base period, and the R +1 (where R is 1 to R) th SSB base period corresponds to the R-th adjustment coefficient identifier of the intermediate node device. The adjustment coefficient is a specific numerical value for adjusting the phase, amplitude, polarization and the like of the network equipment or the terminal equipment by the intermediate node, and the identity of the adjustment coefficient is identified, namely the adjustment coefficient identification.
Examples 1,
The network device controls R adjusting coefficients of the wireless communication node sub-array, a basic beam set formed by L basic beams of the network device is forwarded by the wireless communication node to form an adjusting beam set formed by M-L multiplied by R adjusting beams, and the sending period T of a synchronous broadcast block (SSB) of the network device is R +1 times of 5 ms. The transmission of the R (R ═ 1, 2.., R) th SSB fundamental period corresponds to the adjustment coefficients of the R-th intermediate node.
Taking the 15kHz subcarrier spacing, the frequency band below 3GHz and 3-6GHz as examples, the SSB transmission of NR is as shown in fig. 1, and the SSB transmission time configuration of the prior art.
Preferably, the basic beam transmission basic period is 5 ms. For example, the NR system supports 6 synchronization signal periods, i.e., 5ms, 10ms, 20ms, 40ms, 80ms, 160 ms. In the cell search procedure, the terminal assumes a synchronization signal period of 20 ms. In NR systems, a set of SSBs is limited to a certain 5ms field and starts with the first slot of this field.
Preferably, for each basic beam, the transmission period of the SSB on R +1 beams in total of the basic beam and the adjusted beam is R +1 times the basic period; the basic cycle is a transmission cycle of the SSB without the intermediate node device.
Fig. 2 is an embodiment of SSB transmission period variation. For example, taking 15kHz subcarrier spacing, frequency bands below 3GHz, and 3-6GHz as examples, an intermediate node is introduced, and an adjustable adjustment coefficient R is 2, then the transmission period of the newly designed SSB becomes 5ms (R +1) × 15ms as shown in the figure.
Further, the number of SSB indexes with intermediate node equipment is R +1 times the number of SSB indexes without intermediate node equipment; the number of bits of SSB index is 3+ log2(R × L), where L is a base number of beams within the base period.
For example, NR R15 supports 5 SSB aggregation patterns that relate to the frequency band in which the current system operates:
the Case A-SSB block is 15kHz subcarrier interval, 0-3GHz, the maximum sending frequency L in a 5ms period is 4, 3GHz-6GHz, and the maximum sending frequency L is 8. The Case B-SSB block is a 30kHz subcarrier interval, 0-3GHz, the maximum sending frequency L in a 5ms period is 4, 3GHz to 6GHz, and the maximum sending frequency L is 8. The Case C-SSB block is 30kHz subcarrier interval, the FDD is divided into two cases of 0-3GHz and 3GHz to 6GHz, and the TDD is divided into two cases of 0-2.4GHz and 2.4-6GHz, wherein the maximum sending frequency L in the 5ms period of the low-frequency band is 4, and the maximum sending frequency L of the high-frequency band is 8. The Case D-SSB block is 120kHz subcarrier interval, and the maximum sending times L in a 5ms period is 64 aiming at the frequency above 6 GHz. The Case E-SSB block is a 240kHz subcarrier interval, and the maximum number of transmissions L in a 5ms period is 64 for frequencies above 6 GHZ. For 5 types of cases, the maximum number L of SSBs sent in an SSB period is 4/8/64, the index of each SSB ranges from 0 to L-1, and the UE needs to obtain the index information of the current SSB block from the PBCH block to obtain the complete downlink timing of the air interface.
The number of the transmitted extended base SSBs is (R +1) × L, and when 3GHz, the number of the transmitted extended base SSBs is 12, and SSB indexes can be identified as SSB0, SSB1, SSB2, SSB3, …, and SSB 11.
Examples 2,
Further, the DM-RS sequence initialization scrambling code sent by the (r +1) th SSB is a function of the identity of the (r) th adjustment coefficient, and the function value varies with the value of the identity of the adjustment coefficient.
The initialization of PBCH DM RS sequence introduces an RIS adjustment coefficient identification ID (RID) used for distinguishing the sending of the DM RS sequence of PBCH corresponding to different adjustment coefficients.
For example, taking 15kHz subcarrier spacing, frequency bands below 3GHz, and 3-6GHz as examples, an intermediate node is introduced, and the adjustable number of adjustment coefficients R is 2, then as shown in the figure, the base period of the newly designed SSB becomes 5ms × (R +1) ═ 15ms, the number of transmission of the extended base SSB is (R +1) × L, and in the case of 3GHz, the number of transmission of the extended base SSB is 12, and the SSB indices may be identified as SSB0_0, SSB0_1, SSB0_2, SSB0_3, SSB1_0, SSB1_1, SSB1_2, SSB1_3, SSB2_0, SSB2_1, SSB2_2, SSB2_3, that is, the index (RID) of the adjustment coefficients is combined with the SSB index block (SSB _ index) corresponding to each adjustment coefficient.
The DM RS sequence for the SSB block is gold sequence
Sequence generated initiator addition RIS regulation marker
When L is 4 here,
the UE can obtain the SSB low-3-bit index information by checking DM RS, and can simultaneously obtain the half radio frame identification (indicating whether PBCH is transmitted in the first half subframe or the second half subframe of the frame) when L>Time 4
The UE will obtain the SSB index of the lower 3 bits by checking the detected PBCH DM RS.
A part of SSB index information carried by the PBCH DM RS is at most 3 bits and is the lower 3 bits of the SSB index. In one embodiment, the NR PBCH DM RS sequence is a random sequence generated by Gold sequence with order 31 and adjusted by QPSK to obtain the desired DM RS sequence. When the number L of SSBs in the SSB burst set is 4, the parameters used for scrambling sequence initialization include PCID, half radio frame identification, and SSB index. When the maximum number of SSBs L in each SSB burst set is 64, the parameters used for scrambling sequence initialization include PCID and 3 LSBs (low bit) of SSB index. When L is 4 or 8, the UE may obtain 3 low bit index information of the SSB by checking the DM RS, and may even obtain the half radio frame identification at the same time. When L is 64, the UE will obtain 3 LSBs of the SSB index by detecting the PBCH DM RS.
By adding the function f (RID) related to RID, the interference between SSB blocks sent by different RIS adjusting coefficients can be inhibited, the terminal can distinguish the corresponding RIS adjusting coefficients (RID) during detection, and the initialization function of DM RS of each SSB block corresponding to the adjusting coefficient RID is added into the function f (RID) of RID. Recommended f (RID) RID, or
The RIS adjustment coefficient (RID) may further include a plurality of different RIS entities, which are identified by RIS IDs, and the RIS ID corresponding to each RIS entity has a different adjustment coefficient, where the RIS adjustment coefficient is the sum of the adjustment coefficients corresponding to all RIS entities.
The terminal can identify which adjustment coefficient (RID) the corresponding beam is by blindly detecting the PBCH DM RS, and identify the lower 3 bits (issb), and the index value of the SSB can be obtained by combining the upper 3 bits of the broadcast signaling. This approach does not require an increase in the number of bits of the broadcast signaling. The lower 3 bits, in combination with the upper 3 bits, for a total of 6 bits, may indicate a maximum of 64 SSB index values.
In the embodiment of the present application, the value of R is preset or indicated to the terminal device by signaling. Preferably, the preset R value is a maximum value of the adjustment capability of the intermediate node device.
The network equipment controls R adjusting coefficients of a wireless communication node sub-array, a basic beam set formed by L basic beams of the network equipment is forwarded by the wireless communication node to form an adjusting beam set formed by M-L multiplied by R adjusting beams, and the bit number of an SSB index of a broadcast channel is increased to 3+ log2(R × L) bits, where the value of R is the value of the intermediate node's capability to adjust in the system.
Due to the introduction of the intermediate node, the number of SSB indexes is increased from L to (R +1) multiplied by L, so that the bit number of the SSB indexes is also increased to 3+ log2(R × L) bits. Lower 3 bits, terminal still indicates existing SSB index without opening RIS, and newly added log2The (R × L) bit is used to indicate the newly added SSB index.
Fig. 3 is a flowchart of an embodiment of a method of the present application for a network device.
The method of any one embodiment of the first aspect of the present application, for a network device, includes the following steps 201-204:
Optionally, the value of R is indicated to the terminal by the base station.
Optionally, R ═ RmaxIs predefined according to the middle of the systemThe regulation capability of the node and the number of multiple panels define a maximum value.
And determining the transmission period of all SSBs on the R +1 wave beams to be R +1 times of the basic period. The basic period is a transmission period of the basic beam SSB without the intermediate node device.
The number of bits of SSB index is 3+ log2(R×L)。
After any 1 basic wave beam of the network equipment passes through the intermediate node equipment, R adjusting wave beams are formed; the 1 base beam and the R adjustment beams respectively correspond to 1 SSB base period, and the R +1 (where R is 1 to R) th SSB base period corresponds to the R-th adjustment coefficient identifier.
And when the network equipment sends the SSB, implementing DM-RS sequence initialization scrambling code, wherein the DM-RS sequence initialization scrambling code sent by the (r +1) th SSB is a function of the (r) th adjustment coefficient identifier, and the function value is changed along with the value of the adjustment coefficient identifier.
And step 204, receiving the SSB response signal, and determining an adjusted beam direction occupied by the response signal according to the adjustment coefficient identifier and/or the SSB index corresponding to the SSB response signal.
In step 204, the network device correspondingly adjusts the adjustment coefficient of the intermediate node according to the SSB optimal beam information reported by the terminal, and sends the beam of the optimal SSB.
Fig. 4 is a flowchart of an embodiment of a method of the present application for a terminal device.
The method of any one embodiment of the first aspect of the present application, applied to a terminal device, includes the following steps 301 to 304:
Since the DM-RS sequence initialization scrambling code sent in the (r +1) th SSB basic period is a function of the identity of the (r) th adjustment coefficient, and the function value varies with the value of the identity of the adjustment coefficient. And determining a DM-RS sequence initialization scrambling code according to a set function, and identifying which adjustment coefficient (RID) the corresponding beam comes from by the terminal through blind detection of the PBCH DM RS.
The terminal equipment identifies low 3 bits (issb), the low bits are obtained by blind detection of PBCH DMRS, and the index value of the SSB can be obtained by combining the high 3 bits of the broadcast signaling and the high bits indicated by the broadcast signaling. And the terminal equipment acquires the index information of the current SSB block from the PBCH block to obtain the complete downlink timing of the air interface.
And step 304, sending an SSB response signal, where the SSB response signal corresponds to the access occasion indicated by the SSB index corresponding to the adjusted beam direction.
It should be noted that:
DM RS of a terminal blind detection SSB block acquires SSB index low 3 bit positions, and then PBCH broadcast signaling is decoded to acquire high log2(R × L) bits.
And the terminal blindly detects the DM RS of the SSB block to obtain the lower 3 bits of the SSB index and the corresponding adjustment coefficient identification, and then decodes the PBCH broadcast signaling to obtain the higher 3 bits.
The two methods can acquire the adjustment coefficient of the intermediate device and the optimal beam information of the SSB.
