Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, the technical solutions of the present application will be clearly and completely described below with reference to 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 terminology used in the description of the embodiments section of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the present application.
Fig. 1 is a diagram illustrating a communication system according to an embodiment of the present application. As shown in fig. 1, the base station 110 and the user equipment 120 communicate based on the NR protocol.
In Rel-15 NR, the ue 120 obtains time-frequency Synchronization of a cell and obtains a physical layer cell ID of the cell through a Primary Synchronization Signal (PSS) and a Secondary Synchronization Signal (SSS), which is generally called cell search.
The PSS, SSS and Physical Broadcast Channel (PBCH) constitute a synchronization signal block (SS/PBCH block, SSB).
Each synchronization signal block has a predetermined time domain position. This time domain location may also be referred to as a candidate synchronization signal block. Multiple blocks of synchronization signals constitute one SS-burst. A plurality of synchronization signal blocks form a synchronization signal burst. The plurality of synchronization signal bursts constitute an SS-burst-set (set of synchronization signal bursts). The maximum number of SSBs that can be contained in the synchronization signal burst set is Lmax, for example, for an SSB of 120kHz subcarrier spacing, the base station uses 64 SSB beams at most, and Lmax is 64.
The time domain positions of the Lmax synchronization signal blocks are defined within a 5ms window (SSB window) in one SSB period, e.g., for an SSB of 120kHz subcarrier spacing, the 5ms window (SSB window) contains the time domain positions of 64 SSBs. The time domain positions of Lmax sync signal blocks are fixed within a 5ms window. The time domain position indices of the Lmax sync signal blocks are arranged consecutively, from 0 to Lmax-1. The transmission time instant of a synchronization signal block within this 5ms window is fixed and the index is also fixed.
Generally, the base station transmits the synchronization signal block by using a beam sweeping (beam sweeping), that is, the base station transmits the synchronization signal block at different time domain locations through different beams, and accordingly, the user equipment may measure the different beams and sense on which beam the received signal is strongest.
The base station 110 transmits the SSB to the user equipment 120. In an application scenario, the SSB is assumed to have a period of 20 ms, which is a typical configuration. For a 120kHz subcarrier spaced SSB, when the base station employs 64 SSB beams, the duration of the SSB within one SSB period is 5ms, so the total duration of the SSB within 100 ms is 25 ms, much larger than the 10 ms condition for short control signaling.
To configure SSBs as short control signaling, the present application provides an SSB packet-based communication scheme. Specifically, the base station 110 divides a plurality of SSB beams originally transmitted in one SSB period into m SSB groups (m is an integer greater than 1), and transmits the m SSB groups in m consecutive SSB periods (one SSB group is transmitted in each SSB period). Thus, the transmission of the SSBs is spread over a plurality of SSB cycles, and the duration of the SSBs corresponding to a fixed time interval is reduced, thereby meeting the need for short control signaling. The user equipment 120 receives m SSB groups in consecutive m SSB periods, wherein 1 SSB group is received in each SSB period.
For example, fig. 2 is a timing diagram of a communication process according to an embodiment of the present application. For SSBs of 120kHz subcarrier spacing, 64 SSBs (beams) are transmitted in one SSB period when the SSBs are not configured as short control signaling. When the SSBs are configured as short control signaling, as shown in fig. 2, the base station 110 divides 64 SSBs into 4 SSB groups (SSB group 01 to SSB group 04), each SSB group having 16 SSBs therein, and each SSB group transmits in one SSB period (20 msec) (S201 to S204).
Thus, 64 SSBs are sent using 4 SSB periods, which take 80 ms altogether, and the total duration of the 4 SSB groups is 8 ms, which satisfies that the total duration of the SSBs is less than 10 ms within 100 ms, i.e. the condition of short control signaling is satisfied.
Further, since the base station 110 employs the SSB grouping scheme, a plurality of SSBs that should be sent in one SSB period are sent in a plurality of SSB periods, respectively, and thus, the original scheme for confirming the SSB time domain position is no longer applicable to the application scenario of a plurality of sets of SSBs. After the packet mode is introduced, the user equipment 120 needs to acquire the time domain location of the SSB.
Therefore, the present application proposes a new SSB reception method, which is performed by the user equipment 120. In the SSB reception method proposed in the present application, the user equipment 120 determines the time domain position of the SSB group.
In an application scenario of a specific implementation, a plurality of different schemes may be adopted to determine the time domain position of the SSB group. Specific implementations are listed below.
In a first implementation, after the grouping manner is introduced, different SSB periods correspond to different SSB groups, and time domain positions of the different SSB groups within a 5ms window are different. For example, the base station 110 divides a plurality of SSB beams originally transmitted in one SSB period into m SSB groups (m is a positive integer), and transmits the m SSB groups in m consecutive SSB periods (one SSB group is transmitted in each SSB period). In the ith SSB period of the m SSB periods, the time domain position of the SSB group is the time domain position of the nth i to the nth (i + 1) -1 SSB within the 5 millisecond window, wherein i is the number of the SSB periods in the m SSB periods, i is an integer from 0 to m-1, and n is the number of the SSBs in the SSB group. The 5ms window is the half frame where the SSB is located.
Taking the application scenario shown in fig. 2 as an example, for the SSB with 120kHz subcarrier spacing, when the SSB is not configured as the short control signaling, 64 SSBs are sent in one SSB period, and the time domain positions of the 64 SSBs are the time domain positions of the 0 th to 63 th SSBs within the 5 millisecond window in the SSB period. After configuring the SSBs as short control signaling, the base station 110 divides 64 SSBs into 4 SSB groups (SSB group 01 to SSB group 04), and transmits the SSBs in 4 SSB periods (S201 to S204), that is, m =4,n =16.
In one embodiment, N = N/m, where N is the total number of time domain positions of the SSB within the 5 millisecond window, e.g., N =64. Likewise, the base station 110 may divide the 64 SSBs into 4 SSB groups, i.e., m =4.
In the 0 th SSB period S201 (within the first 20 msec), the time domain position of the SSB group 01 is the time domain position of the 0 th to 15 th SSBs within the 5 msec window; in the 1 st SSB period S202 (within the second 20 ms), the time domain position of the SSB group 02 is the time domain position of the 16 th to 31 th SSBs within the 5ms window; in the 2 nd SSB period S203 (in the third 20 msec), the time domain positions of the SSB group 03 are the 32 nd to 47 th SSBs time domain positions in the 5 msec window; in the 3 rd SSB period S204 (in the fourth 20 ms), the SSB group 04 time domain positions are the 48 th to 63 rd SSB time domain positions within the 5ms window.
Thus, in the first implementation, the user equipment 120 determines the time domain location of the SSB within the SSB period. Specifically, the user equipment 120 determines the time domain location of the SSB within the SSB period according to the index or number of the SSB period.
In an embodiment of the first implementation manner, the user equipment 120 determines that the time domain position of the SSB in the i-th SSB period is the time domain position of the nth × i to the nth × (i + 1) -1 SSB in the 5ms window, where i is an index or a number of the SSB period, i is an integer from 0 to m-1, m is a positive integer, and n is a positive integer.
In another embodiment of the first implementation, the user equipment 120 determines the time domain position of the SSB in the 0 th SSB period to be the time domain position of the 0 th to 15 th SSB within the 5 msec window, determines the time domain position of the SSB in the 1 st SSB period to be the time domain position of the 16 th to 31 th SSB within the 5 msec window, determines the time domain position of the SSB in the 2 nd SSB period to be the time domain position of the 32 th to 47 th SSB within the 5 msec window, and determines the time domain position of the SSB in the 3 rd SSB period to be the time domain position of the 48 th to 63 th SSB within the 5 msec window, that is, m =4, n =16.
In another embodiment of the first implementation, N = N/m, where N is the total number of SSBs within the 5 millisecond window, e.g., N =64. Likewise, the base station 110 may divide the 64 SSBs into 4 SSB groups, i.e., m =4.
In a first implementation, the user equipment 120 needs to determine the index or number of the acquisition SSB period. To implement the first implementation manner, the ue 120 determines the index or number of the SSB period according to the system frame number corresponding to the SSB.
For example, after the packet mode is introduced, the ue 120 performs cell search to find an SSB; the user equipment 120 acquires a System Frame Number (SFN) corresponding to the SSB, and the user equipment 120 acquires the System Frame Number by decoding a physical broadcast channel in the SSB and acquires an index or a Number of an SSB period by the System Frame Number; the user equipment 120 obtains the time domain position of the SSB in the SSB period by the index or number of the SSB period; the user equipment 120 obtains timing information (intra-frame timing) from the time domain location of the SSB.
Specifically, in an embodiment of the first implementation, the user equipment 120 determines that the index or number of the SSB period is F/s, where F is a system frame number corresponding to the SSB, and s is a frame number corresponding to one SSB period. In order to satisfy the condition of short control signaling (time sparseness), one SSB period is 10 ms or more, that is, one SSB period corresponds to at least one frame, so s is a positive integer.
For example, one SSB period contains two system frames. When the system frame number corresponding to the SSB is 0, the user equipment 120 determines that the index or number of the SSB period is 0; when the system frame number corresponding to the SSB is 2, the user equipment 120 determines that the index or number of the SSB period is 1; when the system frame number corresponding to the SSB is 4, the user equipment 120 determines that the index or number of the SSB period is 2; when the system frame number corresponding to the SSB is 6, the ue 120 determines that the index or number of the SSB period is 3.
Generally, the user equipment 120 obtains the SSB actually transmitted within the 5ms window through the SSB location high layer parameter (e.g., SSB-positioninburst). In the first implementation, the meaning of the SSB location higher layer parameters will change due to the introduction of the SSB packet. Specifically, the user equipment 120 obtains the SSBs actually transmitted in m periods or the SSBs actually transmitted in a 5ms window in each of the m periods through the SSB location higher layer parameters. For example, the user equipment 120 obtains the SSBs actually transmitted in 4 periods through the SSB location high-level parameters, or obtains the SSBs actually transmitted in a 5ms window in each of the 4 periods, that is, obtains the SSBs actually transmitted in the SSB group (16 SSBs) in each period.
In a second implementation manner, multiple SSB periods corresponding to multiple SSB groups are combined into an SSB extended period (the extended SSB period at least includes m consecutive SSB periods for sending m SSB groups), and different SSB groups correspond to different system frame numbers of the SSB extended period. Note: currently, the system frame number of the SSB in one cycle is the same. The user equipment 120 determines the system frame number corresponding to the SSB group in the SSB extension period according to the index or number of the SSB period in the SSB extension period.
Specifically, in an embodiment, the base station 110 divides a plurality of SSB beams originally transmitted in one SSB period into m SSB groups (m is an integer greater than 1), and transmits the m SSB groups in m consecutive SSB periods respectively (each SSB period transmits one SSB group).
Assume that each SSB period contains two system frames, the system frame numbers of the SSB periods are 0 and 1. The extended SSB period includes m consecutive SSB periods for transmitting m SSB groups, a 0 th system frame of a first SSB period of the m consecutive SSB periods is a 0 th system frame of the extended SSB period, a 1 st system frame of the first SSB period of the m consecutive SSB periods is a 1 st system frame of the extended SSB period, a 0 th system frame of a second SSB period of the m consecutive SSB periods is a 2 nd system frame of the extended SSB period, and so on.
Since the SSB group (5 ms window) is located in the 0 th system frame of the SSB period, the system frame number of the SSB group in the extended SSB period in the ith SSB period of the m consecutive SSB periods is s (i-1), where s is the frame number corresponding to one SSB period.
Taking the application scenario shown in fig. 2 as an example, for an SSB of 120kHz subcarrier spacing, the period of one SSB is 20 ms, which contains two system frame numbers. Extending the period of SSB from 20 ms to 100 ms, and within the first 20 ms (the first SSB period S201), the system frame number of the SSB group is 0; within the second 20 ms (second SSB period S202), the sfn of the SSB group is 2; in the third 20 ms (third SSB period S203), the system frame number of the SSB group is 4; within the fourth 20 ms (fourth SSB period S204), the system frame number of the SSB group is 6.
According to the first implementation manner and the second implementation manner, the total duration of the 4 SSB groups is 8 milliseconds within 100 milliseconds, and the condition that the total duration of the SSBs is less than 10 milliseconds within 100 milliseconds, that is, the short control signaling condition is satisfied, can be satisfied. Neither of these implementations changes the 5-millisecond time index inside the SSB (provided by the 4-bit information of the PBCH Demodulation Reference Signal (DMRS) sequence and the 4-bit information of the PBCH payload) nor the field indication inside the SSB (provided by the 1-bit information of the PBCH payload). Since the indication of the system frame number in the SSB changes, the ue performs soft combining (forming an SSB extension period) among multiple periods, and needs to perform special processing on the low bit position of the system frame number, so as to avoid bit difference at the low bit position of the system frame number during soft combining, which is the same as the current processing of the ue.
Further, after the base station 110 configures the SSB as the short control signaling, the ue 120 needs to know that the SSB is the short control signaling. To this end, the present application also proposes an SSB receiving method in which the user equipment 120 determines the SSB as short control signaling.
When the user equipment 120 determines that the SSB is short control signaling, the receiving method of the SSB in the first or second implementation may be used (when the SSB is 120kHz subcarrier spacing).
In an implementation scenario, the SSB may be determined as short control signaling by using various schemes. Specific implementations are listed below.
In a third implementation, the ue 120 determines the SSB to be the short control signaling according to a Master Information Block (MIB) or a System Information Block (SIB).
In the fourth implementation, the user equipment 120 determines the SSB as the short control signaling according to a Burst Transmission Window (DBTW). Specifically, the Burst Transmission Window (DBTW) is to cope with LBT, so that the base station has more opportunities to transmit the SSB, and when the SSB is a short control signaling, the base station can transmit the SSB without LBT, and the DBTW has no meaning. Therefore, when the user equipment 120 knows that the Discovery Burst Transmission Window (DBTW) is not configured, the user equipment 120 knows that the SSB is short control signaling.
In a fourth implementation, the user equipment 120 determines a short control signaling window and determines the SSB within the short control signaling window to be short control signaling.
Specifically, a short control signaling window is defined, the base station 110 configures the short control signaling window, and sends the SSB that needs to be configured as the short control signaling in the short control signaling window. The user equipment 120 receives the SSB within a short control signaling window. By configuring the short control signaling window, the base station 110 can tell the user equipment 120 that the SSB need only be measured within the short control signaling window.
In a simplified manner, the period and duration of the short control signaling window, at which the short control signaling window has a relatively fixed transmission occasion and duration on each transmission occasion within a time interval, can be directly defined.
In a more complex manner, a set of short control signaling windows is defined within a time interval (e.g., a first time interval), and the transmission occasions and the duration of the set of short control signaling windows on each transmission occasion within the time interval are defined. For example, a group of short control signaling windows is defined to have a transmission opportunity of 20 ms each (i.e. transmission starting point is 0 th, 20 th, 40 th, 60 th, 80 th ms) within 100 ms, and a duration of 2 ms on each transmission opportunity, so that the total transmission time is 10 ms within 100 ms, and the short control signaling condition is satisfied. Or, the period of the short control signaling window is directly defined to be 20 milliseconds, the duration is 2 milliseconds, the effect is the same, and the total sending time is 10 milliseconds within 100 milliseconds, so that the short control signaling condition is met.
The user equipment 120 determines a set of short control signaling windows within a first time interval (e.g., 100 milliseconds). For example, the user equipment 120 determines the transmission occasions of a set of short control signaling windows within a first time interval and the duration on each transmission occasion. As another example, the user equipment 120 determines the period and duration of the short control signaling window.
Further, the first time interval is a duration associated with the definition of the short control signaling, e.g., 100 milliseconds, which is not a periodic time period. Therefore, directly defining the period and duration of the short control signaling window may lead to inconsistent occurrence of the short control signaling window in different 100 ms, and thus, the period and duration of the short control signaling window may be limited to be valid only in a first time interval. Specifically, in one embodiment, the user equipment 120 also determines whether the period and duration of the short control signaling window is valid for only one first time interval.
Further, in an embodiment, to simplify the configuration overhead, only the transmission occasions of the short control signaling window are configured, and the duration on each transmission occasion is defined to be the same. Under this definition, the ue 120 knows the transmission occasions (number) within a first time interval (e.g., within 100 ms), and can derive the duration (e.g., 100 ms divided by the number of transmission occasions) of each transmission occasion.
It is to be understood that some or all of the steps or operations in the above-described embodiments are merely examples, and other operations or variations of various operations may be performed by the embodiments of the present application. Further, the various steps may be performed in a different order presented in the above-described embodiments, and it is possible that not all of the operations in the above-described embodiments are performed.
Further, in the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical blocks. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by an accessing party. A digital device is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate a dedicated integrated circuit chip. Furthermore, nowadays, instead of manually manufacturing an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as ABEL (Advanced Boolean Expression Language), AHDL (alternate Hardware Description Language), traffic, CUPL (core universal Programming Language), HDCal, jhddl (Java Hardware Description Language), lava, lola, HDL, PALASM, rhyd (Hardware Description Language), and vhigh-Language (Hardware Description Language), which is currently used in most popular applications. It will also be apparent to those skilled in the art that hardware circuitry for implementing the logical method flows can be readily obtained by a mere need to program the method flows with some of the hardware description languages described above and into an integrated circuit.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer readable medium that stores computer readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and embedded microcontrollers, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, atmel AT91SAM, microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
