Referring to fig. 1, fig. 1 is a block diagram of a wireless communication system to which an embodiment of the present invention is applicable. The wireless communication system includes a terminal 11 and a network-side device 12. The terminal 11 may also be referred to as a terminal Device or a User Equipment (UE), where the terminal 11 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device, and the specific type of the terminal 11 is not limited in the embodiment of the present invention. The network-side device 12 may be a Base Station or a core network, wherein the Base Station may be a 5G or later-version Base Station (e.g., a gNB, a 5G NR NB, etc.), or a Base Station in other communication systems (e.g., an eNB, a WLAN access point, or other access points, etc.), or a location server (e.g., an E-SMLC or an lmf (location Manager function)), wherein the Base Station may be referred to as a node B, an evolved node B, an access point, a Base Transceiver Station (BTS), a radio Base Station, a radio Transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, or some other suitable terminology in the field, as long as the same technical effect is achieved, the base station is not limited to a specific technical vocabulary, and it should be noted that, in the embodiment of the present invention, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.
The base stations may communicate with the terminals 11 under the control of a base station controller, which may be part of the core network or some of the base stations in various examples. Some base stations may communicate control information or user data with the core network through a backhaul. In some examples, some of the base stations may communicate with each other, directly or indirectly, over backhaul links, which may be wired or wireless communication links. A wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on the multiple carriers simultaneously. For example, each communication link may be a multi-carrier signal modulated according to various radio technologies. Each modulated signal may be transmitted on a different carrier and may carry control information (e.g., reference signals, control channels, etc.), overhead information, data, and so on.
The base station may communicate wirelessly with the terminal 11 via one or more access point antennas. Each base station may provide communication coverage for a respective coverage area. The coverage area of an access point may be divided into sectors that form only a portion of the coverage area. A wireless communication system may include different types of base stations (e.g., macro, micro, or pico base stations). The base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. The base stations may be associated with the same or different access networks or operator deployments. The coverage areas of different base stations (including coverage areas of base stations of the same or different types, coverage areas utilizing the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.
The communication link in the wireless communication system may include an Uplink for carrying Uplink (UL) transmission (e.g., from the terminal 11 to the network side device 12), or a Downlink for carrying Downlink (DL) transmission (e.g., from the network side device 12 to the terminal 11), and a Sidelink (SL, or vice link, Sidelink, etc.) for carrying transmission between the terminal 11 and other terminals 11. The UL transmission may also be referred to as reverse link transmission, while the DL transmission may also be referred to as forward link transmission. Downlink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both. Similarly, uplink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both.
The base station in Sidelink may be configured or the manufacturer may pre-configure 2 or 3 Synchronization resources (Sync resources) for transmitting (receiving or transmitting) Sidelink-Synchronization Signal Block (S-SSB), as shown in fig. 2, where each Sync Resource includes 1-64 resources required for S-SSB transmission. The user will select one Sync Resource from which to send S-SSBs and receive S-SSBs on the remaining Sync resources.
Before performing the sildelink transmission, the sildelink user needs to determine a Synchronization source (Synchronization reference source, which may also be referred to as a Synchronization reference, or a timing reference), and the transmission of the sildelink user is performed based on the obtained timing, and the Synchronization source of the user may be a base station, a Global Navigation Satellite System (GNSS), a timing generated by a local clock of the user, or a timing provided by another user. Specifically, one sildelink user can send out its own timing information by sending an S-SSB, and other users can use the sildelink user as their own synchronization source by receiving the S-SSB and acquiring the timing information.
Usually, the user will search for the S-SSB or GNSS or base station within a certain range and select the one with the best quality or highest priority as the synchronization source.
Different Sync resources usually have different time domain locations, for example, assuming that there are two Sync resources available for transmitting one S-SSB on carrier 1, Sync Resource1 in the pre-configuration includes one slot, slot1 located at Direct frame number 1 (DFN), and Sync Resource2 includes one slot, slot2 located at DFN 1.
In the related technology, a Sidelink user can acquire the timing information (frame level timing 10bit + slot level timing 7bit) of the received S-SSB only after decoding PSBCH, and can determine which Sync Resource the received S-SSB belongs to, thereby further determining which Sync Resource the user wants to receive the S-SSB on, and which Sync Resource can be used for sending the S-SSB.
Embodiments of the present invention provide a method and an apparatus for processing sidelink reference signal, and a communication device, which enable a user to determine partial timing information or even all timing information before decoding a PSBCH, thereby obtaining timing information in advance, reducing overhead of timing information in the PSBCH, and reducing complexity of PSBCH decoding.
An embodiment of the present invention provides a method for processing a sidelink reference signal, which is applied to a sending end terminal, and as shown in fig. 3, the method includes:
step 101: generating a sidelink reference signal sequence based on first information, the first information comprising at least part of bits of at least one of the following parameters: the sequence number, the time slot index and the S-SSB index of the side link synchronization signal block of the synchronization resource;
step 102: and sending the sidelink reference signal sequence on the resource corresponding to the first information.
In this embodiment, the sending end terminal generates a sidelink reference signal sequence based on first information, where the first information includes at least part of bits of at least one of the following parameters: and sending a side link reference signal sequence on a Resource corresponding to the first information by using the serial number, the slot index and the S-SSB index of the Sync Resource. Through the technical scheme of the invention, at least part of bits of information such as the serial number of the Sync Resource, the slot index, the S-SSB index and the like are carried in the sidelink reference signal sequence, so that a user can determine part of timing information or even all timing information before decoding the PSBCH, thereby acquiring the timing information in advance, reducing the overhead of the timing information in the PSBCH and reducing the decoding complexity of the PSBCH.
In an exemplary embodiment of the present invention, the sending end terminal may determine the first information through at least one of the following manners;
determining the first information through configuration information of network side equipment;
determining the first information by pre-configured information;
determining the first information through a protocol definition;
the first information is determined by the indication of other users.
In an exemplary embodiment of the present invention, a manner for a sending end terminal to send the sidelink reference signal sequence on a resource corresponding to the first information may include at least one of the following:
sending the sidelink reference signal sequence at a Resource position corresponding to the sequence number of the Sync Resource;
sending the sidelink reference signal sequence at a resource position corresponding to the slot index;
and sending the sidelink reference signal sequence at the resource position corresponding to the S-SSB index.
An embodiment of the present invention provides a method for processing a sidelink reference signal, which is applied to a receiving end terminal, and as shown in fig. 4, the method includes:
step 201: receiving a sidelink reference signal sequence;
step 202: determining first information according to the sidelink reference signal sequence, wherein the first information comprises at least part of bits of at least one of the following parameters: sequence number of synchronization resource, slot index and side link synchronization signal block S-SSB index.
In this embodiment, the receiving end terminal receives the sidelink reference signal sequence, and determines first information according to the sidelink reference signal sequence, where the first information includes at least part of bits of at least one of the following parameters: the Sync Resource sequence number, slot index, and S-SSB index. Through the technical scheme of the invention, at least part of bits of information such as the serial number of the Sync Resource, the slot index, the S-SSB index and the like are carried in the sidelink reference signal sequence, so that a user can determine part of timing information or even all timing information before decoding the PSBCH, thereby acquiring the timing information in advance, reducing the overhead of the timing information in the PSBCH and reducing the decoding complexity of the PSBCH.
In the exemplary embodiment of the present invention, the determining, by the receiving end terminal, the first information according to the sidelink reference signal sequence may include at least one of:
determining the serial number of the received Sync Resource where the side link synchronization signal block S-SSB is;
determining a slot index of the received S-SSB;
an S-SSB index of the received S-SSB is determined.
In an exemplary embodiment of the present invention, the receiving end terminal may determine, according to the first information, at least one of the following:
a synchronization resource for transmission;
a synchronization resource for receiving;
the S-SSB is used as a synchronous resource of a synchronous reference;
at least part of the sidelink timing information.
In the above embodiments, the Reference Signal may be at least one of Channel State Information (CSI) -Reference Signal (RS), Phase-Tracking (PT) -RS, Sounding Reference Signal (SRS), Tracking Reference Signal (TRS), Demodulation Reference Signal (DMRS), and the like.
In a specific example, assuming that Sync Resource contains X S-SSBs, since Sync Resource uniquely corresponds to one or a group of resources, for example, when X ═ 1, Sync Resource uniquely corresponds to one frame number and one intra slot, that is, complete slot timing information of 7 bits can be determined; when X >1, the Sync Resource uniquely corresponds to X slots, and further the serial number of each slot in the Sync Resource can be determined by combining the S-SSB index.
Therefore, the RS carrying Sync Resource can help the user to obtain at least part of timing related information before decoding the PSBCH, so that the overhead of the timing information carried in the PSBCH can be reduced. For some cases, for example, in the Sidelink dedicated frequency band of FR1, it may be considered that all the time domain resources may be used for Sidelink, and at this time, X is less than 4, so that the DMRS carries 2bit Sync Resource sequence number +2bit S-SSB index to provide complete timing related information, so that the user does not need to decode the PSBCH each time.
Specifically, the PSBCH RS is generated based on the first information, for example, the initial value c of the pseudo-random scrambling code sequence can be determined based on the first informationinitThe information includes at least partial bits of at least one of a Sync resource sequence number (e.g., 2 bits), a slot index, and an S-SSB index.
The technical scheme of the present invention is further explained below by taking PSBCH DMRS as an example of a reference signal.
