Description

Information processing method, device and medium

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on February 26, 2024, with application number 202410210315.2 and invention name “Information Processing Method, Device and Medium,” the entire contents of which are incorporated by reference into this disclosure. Technical Field

[0002] The present disclosure relates to the field of communication technologies, and in particular to an information processing method, device, and medium. Background Art

[0003] Currently, for example, in 2G to 5G mobile communication transmission systems, all are cellular-based. Each cell has a fixed frequency range and pre-planned cell coverage, and multiple cells collaborate to achieve coverage. The access network (base station) assigns a physical layer cell identity (PCI) to each cell and a cell radio network temporary identifier (C-RNTI) dedicated to each connected terminal. This unique identifier is assigned to the terminal within the cell.

[0004] In current mobile communication transmission systems, network-side terminal scheduling and transmission are tied to cells. When a base station or terminal organizes signaling or data to be transmitted onto a corresponding channel for transmission, channel coding is performed. During the channel coding process, scrambling is performed, and the receiving end performs the corresponding descrambling operation to restore the signaling or data. In relevant communication protocols, the generation of scrambling codes for channels communicating with a single terminal requires two identifiers: the cell identifier and the terminal identifier. The cell identifier includes the PCI mentioned above, and the terminal's unique identifier within the cell includes the C-RNTI mentioned above.

[0005] However, with the development of communication technologies, such as 6G wireless communications, the communication needs of wide coverage, full spectrum, and full applications are being pursued. While supporting high throughput, they also require extremely low end-to-end latency to meet the needs of naked-eye 3D services such as the Metaverse. This requires further enhancement of the user experience for high-speed mobile devices, such as high-speed rail. Therefore, the requirement for a consistent user experience is far higher than in previous generations of wireless communication systems. The transmission between the base station and the terminal mentioned above is scrambled using the cell identifier and the terminal's unique identifier within the cell. This approach is not suitable for the consistent scheduling and transmission of terminals within the network required by user-centric networks. Summary of the Invention

[0030] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0031] For ease of explanation, the following focuses on the terminal side to explain the information processing method of the embodiment of the present disclosure. Figure 1 is a flow chart of an information processing method provided by an embodiment of the present disclosure. The method can be executed by an information processing device, wherein the device can be implemented using software and / or hardware and can generally be integrated into a terminal. As shown in Figure 1, the method includes:

[0032] Step 101: Acquire a terminal identifier of a terminal in an area, where the area is larger than a cell.

[0033] In one embodiment of the present disclosure, in order to achieve decoupling between the physical channel and the cell for transmission between the base station and the terminal, a corresponding terminal identifier is generated for the terminal based on the area, and the range of the area corresponding to the terminal identifier is larger than a cell, so that the transmission of the terminal's physical channel will not be affected when the cell is switched.

[0034] Among them, the area is different in different application scenarios. In some possible embodiments, the area can be composed of multiple cells, so that the corresponding terminal identification is the terminal identification within the area composed of multiple cells; in some possible embodiments, the area can be composed of one or more base stations, so that the corresponding terminal identification is the terminal identification within the area composed of one or more base stations; in some possible embodiments, the area can be one or more networks, so that the corresponding terminal identification is the terminal identification within the area composed of one or more networks.

[0035] In this embodiment, a terminal identifier replaces cell-related input parameters, such as the PCI and a unique identifier of the UE within the cell (such as the C-RNTI), as a scrambling code input to scramble physical layer control messages and physical layer transmission data, thereby enabling terminal addressing. Step 102 generates a scrambling code based on the terminal identifier, and scrambles uplink information sent to the base station based on the scrambling code and / or descrambles downlink information sent by the base station.

[0036] The purpose of scrambling is to address UEs and randomize signal transmission to reduce interference.

[0037] In one embodiment of the present disclosure, a scrambling code is generated based on a terminal identifier. The manner of generating the scrambling code may be determined according to a relevant communication protocol. In this embodiment, uplink information sent to a base station may be scrambled according to the scrambling code, and downlink information sent by the base station may be descrambled, wherein the channel for sending uplink information may include a physical uplink shared channel (PUSCH) for uplink transmission sent by the terminal, and the channel for sending downlink information sent by the base station may include a physical downlink control channel (PDCCH) for scheduling and control commands sent by the base station, and a physical downlink shared channel (PDSCH) for transmitting downlink data.

[0038] It should be noted that the entity that generates the terminal identifier for the terminal may include a core network or a base station, and the terminal identifier may be generated by any identification information decoupled from the cell in the corresponding scenario.

[0039] For example, the core network generates a terminal identifier for the terminal device, such as a temporary identifier S-TMSI (SAE Temporary Mobile Station Identifier, S-TMSI) used by the core network as the terminal identifier; for example, different terminal identifier value ranges are reserved for different areas, and the terminal identifier within the reserved value range can be allocated to the accessed terminal as the terminal identifier, etc., wherein, when different terminal identifier value ranges are reserved for different areas, the terminal identifier of a single terminal can be allocated according to a unified planning strategy, wherein the unified planning strategy can be a pre-set initial value of the terminal identifier value and a superposition strategy of the terminal identifier value, and a terminal flag is allocated to the newly accessed terminal according to the superposition strategy and the initial value. For example, if the initial value is 000000000000000, and the superposition strategy is to superimpose 1 each time, then when the first terminal accesses, the allocated terminal identifier is 00000000000001, and when the second terminal accesses, the allocated terminal identifier is 00000000000002, and so on. For example, the core network and the base station jointly generate the terminal identifier. The core network may generate a terminal identifier and the base station may generate a terminal identifier, and subsequent scrambling codes are generated based on the terminal identifiers generated by the core network and the base station.

[0040] In one embodiment of the present disclosure, the terminal identification generated for a single terminal may be one or more.

[0041] In some possible embodiments, a terminal identifier generated for a single terminal is one (which may be generated by a base station or a core network, etc.). When generating a scrambling code based on the terminal identifier, the terminal identifier may be intercepted and processed to obtain at least one identifier sequence, and the scrambling code is generated based on the identifier sequence. The identifier sequence in this embodiment may be understood to replace an input parameter for generating a scrambling code according to a related communication protocol. For example, in a 5G communication protocol, the identifier sequence may replace the aforementioned PCI and C-RNTI.

[0042] It is readily understood that the number of at least one identification sequence obtained by intercepting the terminal identification may be equal to or less than the number of input parameters for generating the scrambling code. The input parameters for generating the scrambling code may all or partly be derived from the identification sequence. When all input parameters for generating the scrambling code are derived from the identification sequence, the scrambling code may be generated using at least one identification sequence as an input parameter.

[0043] For example, taking PDSCH as an example, the initialization formula for scrambling code generation is as follows: init is the scrambling sequence, n RNTI is the unique identifier of UE in the cell, n IDIt can be the above PCI, q can represent the codeword. If two codewords can be transmitted at the same time, q = 0 or 1. If only one codeword can be transmitted, q = 0. K is related to the number of codewords that can be transmitted. If two codewords can be transmitted, K = UE-ID-1 length - 1. If only one codeword can be transmitted, K = UE-ID-1 length: c init =n RNTI 2 K +q·2 K-1 +n ID Formula (1)

[0044] In this embodiment, if the number of at least one identification sequence can be equal to the number of parameters for generating a scrambling code, then at least one identification sequence is used as an input parameter to generate a scrambling code. Continuing with PDSCH as an example, formula (1) can be converted to formula (2): init =n UE-ID-1 2 K +q·2 K-1 +n UE-ID-2 Formula (2)

[0045] Therefore, at least one identification sequence is at least two, and one identification sequence can be taken as the above n UE-ID-1 and n UE-ID-2 , so as to realize generating a scrambling code based on at least one identification sequence as an input parameter.

[0046] When part of the input parameters for generating the scrambling code comes from an identification sequence, at least one identification sequence and other identification sequences of the terminal may be used as input parameters to generate the scrambling code. The other identification sequence is a fixed sequence pre-assigned based on a service of the terminal, or a fixed sequence pre-assigned based on a grouping category of the terminal. Of course, the other identification sequence may also be obtained using other methods, which are not listed here.

[0047] For example, continuing with the above formula (2), at least one identification sequence can be used as the above n UE-ID-1 or n UE-ID-2 One of the two, and the other identification sequence as n UE-ID-1 and n UE-ID-2 Another one in generates scrambling code.

[0048] In addition, in this embodiment, the manner of intercepting and processing the terminal identification to obtain at least one identification sequence varies in different application scenarios:

[0049] In one embodiment of the present disclosure, a terminal identifier is truncated based on the number and length of parameters required for the scrambling codes used by different physical channels to obtain one or more identifier sequences that match the number and length of parameters. The number and length of parameters required for the scrambling codes used by different physical channels can be determined according to the communication protocol. For example, in the 5G communication protocol, the number and length of parameters required for the scrambling codes used by different physical channels are 2 bits and 16 bits, respectively. Furthermore, the different physical channels in this embodiment include a physical downlink control channel (PDCCH), a physical downlink shared channel (PDSCH), and a physical uplink shared channel (PUSCH). That is, in this embodiment, the at least one identifier sequence generated for different physical channels can be completely different or at least partially identical.

[0050] The above-mentioned method of intercepting the terminal identifier based on the number of parameters and parameter length required by the scrambling code used by different physical channels is different in different application scenarios. Any interception method that meets the number of parameters and parameter length should be regarded as applicable in this solution, that is, the interception method can be flexibly set according to the needs of the scenario. The interception methods corresponding to different physical channels or transmission modes can be the same or different. Examples are as follows:

[0051] As an example: when the core network generates a terminal identifier, the temporary identifier S-TMSI used in the system architecture evolution network configured by the core network for the terminal device can be obtained as the terminal identifier. When the terminal identifier is intercepted according to the number of parameters and parameter length required for the scrambling code used by different physical channels, the S-TMSI length is 48 bits. If the input parameter for the scrambling code generation is two n UE-ID-1 and n UE-ID-2 , the parameter length of both input parameters is 16 bits. As shown in Figure 2, for PDCCH, starting from the first bit on the left of the S-TMSI, 16 bits in length are intercepted from left to right as the first identification sequence, and starting from the first bit on the right of the S-TMSI, 16 bits in length are intercepted from right to left as the second identification sequence;

[0052] For PDSCH, starting with the first left bit of the S-TMSI, 16 bits are truncated from left to right as the first identification sequence, and 16 bits in the middle position of the S-TMSI are truncated as the second identification sequence. The middle position can be any position of the S-TMSI relatively close to the middle position. For example, the second identification sequence can be any continuous or discontinuous 16-byte sequence from the 17th to the 40th of the S-TMSI, such as the sequence of bytes 25-40 in the figure;

[0053] For PUSCH, starting with the first bit on the right of the S-TMSI, 16 bits are truncated from right to left as the first identification sequence, and 16 bits in the middle position of the S-TMSI are truncated as the second identification sequence. Similarly, the middle position can be any position of the S-TMSI relatively close to the middle position. The figure is just one possible example.

[0054] As an example: the base station generates a terminal identifier. For example, the base station allocates a 32-bit long sequence A within the area to the terminal. Then, A can be intercepted and processed according to the number of parameters and parameter length required for the scrambling code used in different transmission modes to obtain one or more identification sequences that match the number of parameters and parameter length.

[0055] For example, as shown in FIG3 , for PDSCH, starting with the first bit on the left, 16 bits of length are truncated from left to right for A as the first identification sequence, and starting with the second bit on the left, 16 bits of length are truncated from left to right for A as the second identification sequence.

[0056] For PDSCH, starting from the third bit from the left of the S-TMSI, 16 bits are truncated from left to right as the first identification sequence, and starting from the fourth bit from the left, 16 bits are truncated from left to right for A as the second identification sequence. For PUSCH, starting from the fifth bit from the left of the S-TMSI, 16 bits are truncated from left to right as the first identification sequence, and starting from the sixth bit from the left, 16 bits are truncated from left to right for A as the second identification sequence. In one embodiment of the present disclosure, the terminal identifier is truncated according to the number of parameters and parameter length required for the scrambling code used in different transmission modes to obtain one or more identification sequences that match the number of parameters and parameter length, wherein the different transmission modes may include dynamic scheduling, semi-persistent scheduling, and dynamic scheduling of different MCSs.

[0057] Similarly, the above-mentioned method of intercepting and processing the terminal identifier based on the number of parameters and parameter length required by the scrambling code used in different transmission modes is different in different application scenarios. Any interception method that meets the parameter number and parameter length should be regarded as applicable in this solution and is not listed one by one here.

[0058] In some possible embodiments, there are multiple terminal identifiers. In this embodiment, at least one of the multiple terminal identifiers is configured differently for different physical channels, where the different physical channels include: a physical downlink control channel (PDCCH), a physical downlink shared channel (PDSCH), and a terminal physical uplink shared channel (PUSCH).

[0059] That is, in this embodiment, multiple terminal identifiers may be allocated, wherein the multiple terminal identifiers include at least three different terminal identifiers corresponding to three different physical channels.

[0060] Alternatively, in this embodiment, at least one of the multiple terminal identifiers is configured differently for different transmission modes, where the different transmission modes include dynamic scheduling, semi-persistent scheduling, and dynamic scheduling with different MCSs. That is, in this embodiment, multiple terminal identifiers can be allocated, where the multiple terminal identifiers include at least three different terminal identifiers corresponding to three different transmission modes.

[0061] In this embodiment, when generating a scrambling code based on a terminal identifier, multiple terminal identifiers can be used as input parameters to generate the scrambling code. In some possible embodiments, the multiple terminal identifiers may include a first terminal identifier and a second terminal identifier within a region configured by the base station for the terminal, wherein the first terminal identifier may be a default value, and the default value may be generated in any pre-agreed manner, or may be pre-set, etc. Alternatively, the first terminal identifier may be configured for different physical channels or for different transmission purposes.

[0062] Similarly, in some possible embodiments, the second terminal identifier may also be a default value, which may be generated in any pre-agreed manner, or may be pre-set, etc. Alternatively, the second terminal identifier may be configured for different physical channels or for different transmission purposes.

[0063] In one embodiment of the present disclosure, the first terminal identifier and the second terminal identifier can be used as input parameters to generate a corresponding scrambling code. For example, taking the above embodiment as an example, the first terminal identifier and the second terminal identifier can be used as n respectively. UE-ID-1 and n UE-ID-2 Generate scrambling code.

[0064] That is, in this embodiment, different physical channels or transmission purposes correspond to n UE-ID-1 Can be the same, but different physical channels or transmission purposes corresponding to n UE-ID-2 Different, or, different physical channels or transmission purposes corresponding to n UE-ID-1 Can be different, but different physical channels or transmission purposes correspond to n UE-ID-2 Or, different physical channels or transmission purposes correspond to n UE-ID-1 Can be different, different physical channels or transmission purposes corresponding to n UE-ID-2 It can also be different.

[0065] In one embodiment of the present disclosure, when generating a scrambling code based on a terminal identifier, at least one terminal identifier among multiple terminal identifiers may be intercepted and processed to obtain at least one identifier sequence. The at least one identifier sequence and other uninterrupted terminal identifiers may be used as input parameters to generate the scrambling code. In other words, depending on the scenario, the terminal identifier itself may be used as the input parameter, or the result of the interception and processing of the terminal identifier may be used as the input parameter.

[0066] In some possible embodiments, the terminal identifier is intercepted and processed based on the number of parameters and parameter lengths required for the scrambling codes used by different physical channels to obtain one or more identifier sequences that match the number of parameters and parameter lengths. The number of parameters and parameter lengths required for the scrambling codes used by different physical channels may be determined according to the communication protocol. For example, in the 5G communication protocol, the number of parameters and parameter lengths required for the scrambling codes used by different physical channels may be 2 bits and 16 bits, respectively. In addition, the different physical channels in this embodiment include: a physical downlink control channel (PDCCH), a physical downlink shared channel (PDSCH), a physical uplink shared channel (PUSCH), etc. That is, in this embodiment, the at least one identifier sequence generated for different physical channels may be completely different or at least partially the same.

[0067] In one embodiment of the present disclosure, the terminal identifier is intercepted and processed according to the number of parameters and parameter lengths required for the scrambling codes used in different transmission modes to obtain one or more identifier sequences that match the number of parameters and parameter lengths. The different transmission modes may include dynamic scheduling, semi-persistent scheduling, and dynamic scheduling with different MCSs.

[0068] Similarly, the above-mentioned method of intercepting and processing the terminal identifier based on the number of parameters and parameter length required for the scrambling code used in different transmission modes is different in different application scenarios. Any interception method that meets the number of parameters and parameter length should be regarded as applicable in this solution and is not listed here one by one. As mentioned above, when there are multiple terminal identifiers, the multiple terminal identifiers can be allocated by the core network, or by the base station, or can be jointly allocated by the core network and the base station, that is, the first terminal identifier within the area configured by the core network for the terminal, and the second terminal identifier within the area configured by the base station for the terminal.

[0069] In some possible embodiments, at least one terminal identifier among multiple terminal identifiers may be intercepted and processed to obtain at least one identifier sequence, and the at least one identifier sequence and other terminal identifiers that have not been intercepted and processed may be used as input parameters to generate a scrambling code. For example, the first terminal identifier may be intercepted and processed to obtain an identifier sequence of a certain length, and the identifier sequence and the second terminal identifier may be used as input parameters to generate a scrambling code.

[0070] For example, n UE-ID-1From the base station allocation part, n UE-ID-2 From the core network allocation part, take the last 16 bits of the S-TMSI allocated by the core network to the terminal as n UE-ID-2 The base station may allocate the same first terminal identifier that can be used by all physical channels for the terminal, or different first terminal identifiers allocated for different physical channels (such as PDCCH, PDSCH, PUSCH) or transmission purposes.

[0071] In some possible embodiments, multiple terminal identifiers may be intercepted and processed separately to obtain multiple identifier sequences, and the multiple identifier sequences may be used as input parameters to generate a scrambling code.

[0072] In some possible embodiments, the first terminal identifier may be truncated to obtain an identifier sequence of a certain length, and the second terminal identifier may be truncated to obtain an identifier sequence of a certain length. The identifier sequences may be truncated in different ways for different physical channels or different transmission modes. Furthermore, the two identifier sequences are used as input parameters to generate a scrambling code.

[0073] That is, in the embodiments of the present disclosure, the identification sequences corresponding to different transmission modes or physical channels as input parameters may be partially the same, completely the same, or completely different. The identification sequences corresponding to different input parameters may come from different terminal identifiers, the same terminal identifier, the same interception method of the same terminal identifier, different interception methods of the same terminal identifier, the same interception method of different terminal identifiers, or different interception methods for different terminal identifiers, etc. The specific interception method can be set according to the needs of the scenario and is not limited here.

[0074] In addition, in the scenario where the base station assigns terminal identifiers based on regions, as shown in Figure 4, there is the problem of terminals crossing regions. In this embodiment, when the terminal leaves the previous region and switches to a new region during information transmission, for example, switching from region 1 in the figure to new region 2, in order to not interrupt the relevant data transmission, a scrambling code is still generated based on the terminal identifier in the previous region, and the uplink information sent to the new base station in the new region is scrambled according to the scrambling code. Alternatively, the downlink information sent by the new base station can be descrambled.

[0075] When the terminal has no data transmission or no data transmission with high delay reliability requirements, it receives a signaling message sent by the new base station that is encrypted with the terminal identifier in the previous area, and the signaling message includes the terminal identifier in the new area. The terminal identifier in the new area can be used to scramble the confirmation message sent to the new base station.

[0076] In this embodiment, when the base station reallocates a terminal identifier for a terminal, the physical channel carrying high-level messages (such as RRC messages or MAC layer signaling) that allocate the terminal identifier in the new area is scrambled with the terminal identifier of the old area, and the physical channel carrying the terminal feedback confirmation message is scrambled with the terminal identifier in the new area.

[0077] Continuing with Figure 4, at time T1, a terminal accesses the network. The access network node (base station or AP) in Terminal Identifier Validity Zone 1 assigns the terminal an identifier for physical layer transmission scrambling and addressing. The terminal then uses the assigned terminal identifier in Zone 1 as input to generate a scrambling code to scramble and descramble the terminal's physical channel, enabling physical layer transmission.

[0078] At time T2, the terminal moves out of the terminal identifier valid area 1 and enters valid area 2. At this time, the terminal is performing data transmission. The base station in the new valid area 2 obtains the terminal identifier of the terminal in valid area 1, continues to use the terminal identifier of the valid area 1 as the input of the physical channel scrambling code of the terminal, and performs physical layer transmission with the terminal; at time T3, the base station determines that the terminal has no data transmission or no data transmission with high delay reliability requirements, and allocates a new terminal identifier in valid area 2 for physical layer channel scrambling to the terminal. In the allocation of terminal identifiers in valid area 2, the base station configuration message is scrambled with the terminal identifier of valid area 1, that is, the physical channel of the high-level message (such as RRC message or MAC layer signaling) sent by the base station to the terminal that carries the new terminal identifier in valid area 2 is scrambled with the terminal identifier in valid area 1; the terminal confirmation message is scrambled with the terminal identifier in valid area 2, that is, the physical channel carrying the terminal feedback confirmation message is scrambled with the terminal identifier in valid area 2.

[0079] Furthermore, after the scrambling code is generated, the uplink information sent by the base station can be scrambled according to the scrambling code, and the downlink information sent by the base station can also be descrambled. The following takes the data transmission of the Wulin channel as an example, and the example is explained as follows:

[0080] In the first example, when a terminal accesses the network, the core network assigns it a unique terminal identifier within the network, which can be, for example, an S-TMSI. The terminal stores this identifier and uses it to generate a scrambling code for the physical channel, thereby performing physical layer transmission addressing. When transmitting uplink physical channels, such as the PUSCH, the terminal scrambles based on this identifier. When receiving downlink physical channels, such as the PDCCH and PDSCH, the terminal descrambles based on this identifier. If the descrambled data is received incorrectly, such as when a cyclic redundancy check (CRC) error occurs, the data is considered received incorrectly.

[0081] In the second example, the terminal accesses the network and receives a valid terminal identifier in the area allocated by the base station to the terminal, wherein the terminal identifier can be the same long sequence (such as 32 bits) allocated by the base station for all physical channels, and then a scrambling code of the physical channel related to the UE is generated based on the long sequence. The physical channels include but are not limited to PDCCH, PDSCH, PUSCH, etc.; the terminal identifier can also be a second terminal identifier n allocated by the base station to the terminal for all channels. UE-ID-2 , and the first terminal identifier n for different channels UE-ID-1 Alternatively, the terminal identifier may be a first terminal identifier n assigned by the base station to the terminal for different channels. UE-ID-1 , the second terminal identifier can be a default value, etc.

[0082] In this embodiment, when the terminal receives a downlink physical channel, such as PDCCH or PDSCH, descrambling is performed based on the terminal identifier. For example, when the terminal identifier is the same long sequence assigned by the base station for all physical channels, descrambling is performed based on the long sequence; for example, the terminal identifier is a second terminal identifier n assigned by the base station to the terminal for all channels. UE-ID-2 , and the first terminal identifier n for different channels UE-ID-1 , descrambling is performed based on the second terminal identifier and the first terminal identifier of the corresponding physical channel; for example, the terminal identifier can be the first terminal identifier n for different channels assigned by the base station to the terminal UE-ID-1 , the second terminal identifier can be a default value, and descrambling can be performed based on the first terminal identifier of the corresponding physical channel and the corresponding default value.

[0083] In this embodiment, when the base station sends an uplink physical channel, such as PUSCH, it performs scrambling through the corresponding terminal identifier. For example, when the terminal identifier is the same long sequence assigned by the base station for all physical channels, scrambling is performed based on the long sequence; for example, the terminal identifier is a second terminal identifier n assigned by the base station to the terminal for all channels. UE-ID-2 , and the first terminal identifier n for different channels UE-ID-1 , then scrambling is performed based on the second terminal identifier and the first terminal identifier of the corresponding physical channel; for example, the terminal identifier can be the first terminal identifier n for different channels assigned by the base station to the terminal UE-ID-1 , the second terminal identifier can be a default value, and scrambling can be performed based on the first terminal identifier of the corresponding physical channel and the corresponding default value.

[0084] In the third example, the terminal accesses the network, and the core network assigns a unique identifier within the network to the terminal as a terminal identifier, which may be equal to the S-TMSI, and intercepts the required parameter length (such as 16 bits) as one of the input parameters required to generate the scrambling code for the physical channel. In addition, the terminal identifier assigned by the receiving base station to the terminal is used to generate another input parameter required for the scrambling code based on the corresponding terminal identifier, including one or more of the following: terminal identifier 1 for PDCCH, terminal identifier 2 for PDSCH, and terminal identifier 3 for PUSCH. When the terminal receives a downlink physical channel, such as PDCCH or PDSCH, it descrambles based on the input parameters corresponding to the above terminal identifiers. In this embodiment, if the base station does not assign a corresponding terminal identifier to the corresponding physical channel, a predetermined default terminal identifier may also be assigned to the corresponding physical channel.

[0085] For example, for PDCCH, if the base station assigns terminal identifier 1, PDCCH descrambling is performed based on terminal identifier 1 and the terminal identifier assigned by the core network; if the base station does not assign a terminal identifier, PDCCH descrambling is performed using the default terminal identifier and the terminal identifier assigned by the core network; for PDSCH, if the base station assigns terminal identifier 2, PDSCH descrambling is performed based on terminal identifier 2 and the terminal identifier assigned by the core network; if the base station does not assign terminal identifier 2, PDSCH descrambling is performed based on the default terminal identifier 2 and the terminal identifier assigned by the core network.

[0086] When the terminal sends an uplink physical channel, such as PUSCH, it is scrambled based on the terminal identifier assigned above, specifically including: for PUSCH, if the base station assigns terminal identifier 3, the PUSCH is scrambled based on terminal identifier 3 and the terminal identifier assigned by the core network (for example, S-TMSI); if the terminal identifier 3 is not assigned, the PUSCH is scrambled using the default terminal identifier and the terminal identifier assigned by the core network (for example, S-TMSI).

[0087] It should be emphasized that in the embodiments of the present disclosure, an identification sequence is generated based on the terminal identification, and a scrambling code is generated based on the identification sequence as an input parameter. Therefore, the scrambling and descrambling based on the corresponding terminal identification mentioned in the above example are actually implemented using the input parameters corresponding to the terminal identification during specific execution. The specific method for obtaining the input parameters can be referred to the above embodiment and will not be elaborated here.

[0088] In summary, the information processing method of the embodiment of the present disclosure obtains a terminal identifier in an area larger than one cell, generates a scrambling code based on the terminal identifier, and the terminal scrambles the uplink information sent to the base station according to the scrambling code, and / or descrambles the downlink information sent by the base station. According to the terminal identifier in a larger area larger than the cell, scrambling addressing is performed for the relevant physical channel of the terminal, so that when the base station and the terminal perform physical layer transmission, the physical channel is decoupled from the cell, and user-centric transmission is realized, thereby ensuring the consistent scheduling and transmission of the terminal within the network required by the user-centric network.

[0089] The following focuses on the base station side to illustrate the information processing method of the embodiment of the present disclosure.

[0090] FIG5 is a flow chart of an information processing method provided by an embodiment of the present disclosure. The method can be executed by an information processing device, wherein the device can be implemented using software and / or hardware and can generally be integrated into a base station. As shown in FIG5 , the method includes:

[0091] Step 501: Obtain a terminal identifier of a terminal within a region, where the region is larger than a cell. In one embodiment of the present disclosure, the terminal identifier may be a terminal identifier within the region configured by the core network for the terminal.

[0092] In one embodiment of the present disclosure, the terminal identifier may be a terminal identifier within a region configured by a base station for the terminal. In this embodiment, when the base station configures the terminal identifier for the terminal, the centralized node may obtain an identifier set allocated according to a plan corresponding to the region, and configure the terminal identifier within the region for the terminal based on the identifier set. Different regions correspond to different identifier sets, and the base station configures a unique terminal identifier for the terminal within the identifier set. In one embodiment of the present disclosure, the terminal identifier may be a terminal identifier within the region configured jointly by the base station and the core network.

[0093] Step 502: Generate a scrambling code based on the terminal identifier, perform scrambling processing on downlink information sent to the terminal according to the scrambling code, and / or perform descrambling processing on uplink information sent by the terminal.

[0094] In one embodiment of the present disclosure, the terminal identifier may be one or more. When the terminal identifier includes one, the terminal identifier may be intercepted to obtain at least one identification sequence, and a scrambling code may be generated based on the at least one identification sequence.

[0095] When the terminal identifier is intercepted and processed to obtain at least one identification sequence, the terminal identifier may be intercepted and processed according to the number of parameters and parameter lengths required for the scrambling codes used by different physical channels to obtain one or more identification sequences that match the number of parameters and parameter lengths. The different physical channels include: a physical downlink control channel PDCCH, a physical downlink shared channel PDSCH, and a terminal physical uplink shared channel PUSCH; or,

[0096] The terminal identifier is intercepted and processed according to the number and length of parameters required for the scrambling code used in different transmission modes to obtain one or more identifier sequences that match the number and length of parameters. The different transmission modes include: dynamic scheduling, semi-persistent scheduling, and dynamic scheduling with different MCSs.

[0097] Furthermore, in one embodiment of the present disclosure, at least one identification sequence can be used as an input parameter to generate a scrambling code. If different physical channels or transmission modes have the same number of parameters and parameter length, the corresponding terminal identification interception methods can be the same or different. In other words, the input parameters corresponding to different physical channels or transmission modes can be the same or different.

[0098] In one embodiment of the present disclosure, at least one identification sequence and other identification sequences of the terminal may be used as input parameters to generate a scrambling code. The other identification sequence may be a fixed sequence pre-assigned based on the terminal's service or the terminal's grouping class. Of course, the fixed sequence may also be determined using other possible methods, which are not listed here.

[0099] In the case where the terminal identifier includes multiple terminal identifiers, the multiple terminal identifiers can be the same for different physical channels. For example, two terminal identifiers are included, where one terminal identifier is the same for different physical channels, and the other terminal identifier is also the same for different physical channels; among the multiple terminal identifiers, at least one terminal identifier is configured differently for different physical channels, where the different physical channels include: physical downlink control channel PDCCH, physical downlink shared channel PDSCH, and terminal physical uplink shared channel PUSCH.

[0100] For example, it includes two terminal identifiers, wherein one terminal identifier is the same for different physical channels and the other terminal identifier is different for different physical channels; or it includes two terminal identifiers, wherein one terminal identifier is different for different physical channels and the other terminal identifier is also different for different physical channels. Alternatively, in the case where the terminal identifiers include multiple terminal identifiers, the multiple terminal identifiers can be the same for different transmission modes, for example, it includes two terminal identifiers, wherein one terminal identifier is the same for different transmission modes and the other terminal identifier is also the same for different transmission modes; among the multiple terminal identifiers, at least one terminal identifier is configured differently for different transmission modes, wherein the different transmission modes include: dynamic scheduling, semi-persistent scheduling, and dynamic scheduling with different MCSs.

[0101] For example, it includes two terminal identifiers, wherein one terminal identifier is the same for different transmission modes, and the other terminal identifier is different for different transmission modes; or it includes two terminal identifiers, wherein one terminal identifier is different for different transmission modes, and the other terminal identifier is also different for different transmission modes.

[0102] When generating a scrambling code based on a terminal identifier, multiple terminal identifiers can be directly used as input parameters to generate the scrambling code. Alternatively, at least one of the multiple terminal identifiers can be intercepted to obtain at least one identifier sequence, and the at least one identifier sequence and other uninterrupted terminal identifiers can be used as input parameters to generate the scrambling code. Alternatively, multiple terminal identifiers can be intercepted separately to obtain multiple identifier sequences, and the multiple identifier sequences can be used as input parameters to generate the scrambling code.

[0103] It should be emphasized that the information processing method concentrated on the base station side in the embodiment of the present disclosure corresponds to the above-mentioned information processing method concentrated on the terminal side. Therefore, the relevant processing details on the base station side will not be repeated here.

[0104] The following describes, with reference to a specific example, how to generate a scrambling code based on a terminal identifier, perform scrambling processing on downlink information sent to the terminal according to the scrambling code, and / or perform descrambling processing on uplink information sent by the terminal. The example is as follows:

[0105] The first example: When a terminal accesses the network, the core network assigns it a unique terminal identifier within the network, which can be, for example, an S-TMSI. The base station stores this terminal identifier and uses it to generate the scrambling code for the physical layer channel, thereby performing physical layer transmission addressing. When the base station transmits downlink physical channels, such as the PDCCH or PDSCH, to the UE, it scrambles based on the terminal identifier. When the base station receives uplink physical channels, such as the PUSCH, from the terminal, it descrambles using the terminal identifier. If the descrambled data is received incorrectly, such as with a CRC error, the data is considered to have been received incorrectly or was not sent by the UE.

[0106] The second example: a valid terminal identifier within the area allocated by the base station to the terminal, wherein the terminal identifier can be the same long sequence (such as 32 bits) allocated by the base station for all physical channels, and the scrambling code of the physical channel related to the UE is generated based on the long sequence, and the physical channels include but are not limited to PDCCH, PDSCH, PUSCH, etc.; the terminal identifier can also be a second terminal identifier n allocated by the base station to the terminal for all channels. UE-ID-2 , and the first terminal identifier n for different channels UE-ID-1 Alternatively, the terminal identifier may be a first terminal identifier n assigned by the base station to the terminal for different channels. UE-ID-1 , the second terminal identifier can be a default value, etc.

[0107] In this embodiment, when the base station sends a downlink physical channel, such as PDCCH or PDSCH, scrambling is performed based on the terminal identifier. For example, when the terminal identifier is the same long sequence assigned by the base station for all physical channels, scrambling is performed based on the long sequence; for example, the terminal identifier is a second terminal identifier n assigned by the base station to the terminal for all channels. UE-ID-2 , and the first terminal identifier n for different channels UE-ID-1 , then scrambling is performed based on the second terminal identifier and the first terminal identifier of the corresponding physical channel; for example, the terminal identifier can be the first terminal identifier n for different channels assigned by the base station to the terminal UE-ID-1 , the second terminal identifier can be a default value, and scrambling can be performed based on the first terminal identifier of the corresponding physical channel and the corresponding default value.

[0108] In this embodiment, when receiving an uplink physical channel, such as PUSCH, the base station performs descrambling using the corresponding terminal identifier. For example, when the terminal identifier is the same long sequence assigned by the base station for all physical channels, descrambling is performed based on the long sequence; for example, the terminal identifier is a second terminal identifier n assigned by the base station to the terminal that is common to all channels. UE-ID-2 , and the first terminal identifier n for different channels UE-ID-1, descrambling is performed based on the second terminal identifier and the first terminal identifier of the corresponding physical channel; for example, the terminal identifier can be the first terminal identifier n for different channels assigned by the base station to the terminal UE-ID-1 , the second terminal identifier can be a default value, and descrambling can be performed based on the first terminal identifier of the corresponding physical channel and the corresponding default value.

[0109] The third example: the terminal accesses the network, and the core network assigns a unique identifier within the network to the terminal as the terminal identifier, which may be equal to S-TMSI, for example. The required parameter length (such as 16 bits) is intercepted as one of the input parameters required to generate the scrambling code for the physical channel. In addition, the terminal identifier assigned by the receiving base station to the terminal is used to generate another input parameter required for the scrambling code based on the corresponding terminal identifier, including one or more of the following: terminal identifier 1 for PDCCH, terminal identifier 2 for PDSCH, and terminal identifier 3 for PUSCH. When the base station sends a downlink physical channel, such as PDCCH or PDSCH, it scrambles based on the input parameters corresponding to the above terminal identifiers. In this embodiment, if the base station does not assign a corresponding terminal identifier to the corresponding physical channel, a predetermined default terminal identifier may also be assigned to the corresponding physical channel.

[0110] For example, for PDCCH, if the base station assigns terminal identifier 1, PDCCH is scrambled based on terminal identifier 1 and the terminal identifier assigned by the core network; if the base station does not assign a terminal identifier, PDCCH is scrambled using the default terminal identifier and the terminal identifier assigned by the core network; for PDSCH, if the base station assigns terminal identifier 2, PDSCH is scrambled based on terminal identifier 2 and the terminal identifier assigned by the core network; if the base station does not assign terminal identifier 2, PDSCH is scrambled based on the default terminal identifier 2 and the terminal identifier assigned by the core network.

[0111] When receiving an uplink physical channel, such as PUSCH, the base station performs descrambling based on the terminal identifier assigned above, specifically including: for PUSCH, if the base station assigns terminal identifier 3, descrambling is performed for PUSCH based on terminal identifier 3 and the terminal identifier assigned by the core network; if terminal identifier 3 is not assigned, descrambling is performed for PUSCH using the default terminal identifier and the terminal identifier assigned by the core network.

[0112] It should be emphasized that in the embodiments of the present disclosure, an identification sequence is generated based on the terminal identification, and a scrambling code is generated based on the identification sequence as an input parameter. Therefore, the scrambling and descrambling based on the corresponding terminal identification mentioned in the above example are actually implemented using the input parameters corresponding to the terminal identification during specific execution. The specific method for obtaining the input parameters can be referred to the above embodiment and will not be elaborated here.

[0113] In the information processing solution provided by the embodiments of the present disclosure, a base station generates a scrambling code based on a terminal identifier, scrambles downlink information sent to the terminal based on the scrambling code, and / or descrambles uplink information sent by the terminal. In this technical solution, scrambling addressing is performed for the terminal's related physical channels based on the terminal identifier within a larger area than the cell. This decouples the physical channel from the cell when the base station and the terminal perform physical layer transmission, achieving user-centric transmission and ensuring the consistent scheduling and transmission of terminals within the network, as required by the user-centric network.
