According to the scrambling sequence determining scheme for the multiple transmission points, which is provided by the embodiment of the disclosure, the terminal can acquire network configuration information, and then determine the scrambling sequence of the transmission data of each transmission point based on the network configuration information. According to the content recorded by the R15 protocol, if the terminal judges that only 1 enabled transport blocks corresponding to the transmission data of the transmission points exist, the enabled transport blocks are mapped to the first code word, and when the transmission data of a plurality of transmission points are scheduled by a plurality of PDCCHs, the code word numbers corresponding to the transmission data of different transmission points are identical, so that the transmission data of different transmission points are continuously interfered. According to the embodiment of the disclosure, the transmission data of each transmission point corresponds to different scrambling sequences, so that the interference of the transmission data between the transmission points is reduced, and the performance of the terminal is improved. Next, a detailed description will be given of a scrambling sequence determination scheme for multiple transmission points provided in an embodiment of the present disclosure.
Fig. 1 shows a flowchart of a scrambling sequence determination method of a multi-transmission point according to an embodiment of the present disclosure. As shown in fig. 1, the scrambling sequence determining method for multiple transmission points includes:
Here, the terminal may receive downlink control information (DCI, downlink Control Information) transmitted by the network-side device and acquire network configuration information in the DCI. The terminal may also obtain network configuration information from the higher layer information. The higher layer information may be information from a radio resource control (RRC, radio Resource Control) layer or a media access control (MAC, media Access Control) layer. The network configuration information may include configuration information of transmission resources corresponding to transmission data of the transmission point, such as resourcesAllocation scheme, modulation and coding strategy index value (I MCS Modulation and coding scheme Index), redundancy version number (rv id Redundancy version), etc. Accordingly, the terminal may receive transmission data of at least two transmission points, which may be carried in a physical downlink shared channel (PDSCH, physical Downlink Shared Channel). The transmission point may be a plurality of antenna access points, e.g., base stations, relay stations, etc., distributed over different geographic locations. Each transmission point may independently transmit different data, different transport blocks to the same terminal.
After acquiring the network configuration information and the transmission data of the plurality of transmission points, the terminal may determine a scrambling sequence of the transmission data of each transmission point based on the network configuration information. According to the content recorded in the R15 protocol, in the case that the maxnrofcodewordsschedule bydci of the network configuration information is 2, if only 1 transport block is enabled, the enabled transport blocks are mapped to the first codeword, and the corresponding codeword number is 0. Therefore, when the transmission data of multiple transmission points are scheduled by multiple PDCCHs, codeword numbers corresponding to the transmission data of different transmission points are the same, so that the transmission data of different transmission points will continuously interfere. In the embodiment of the disclosure, the terminal may determine the scrambling sequence of the transmission data of each transmission point according to the network configuration information, and the scrambling sequences of the transmission data of different transmission points are different, so as to avoid interference of the transmission data between the transmission points.
In one possible implementation manner, when determining the scrambling sequence of the transmission data of each transmission point based on the network configuration information, if the terminal acquires the network configuration information through the received downlink control information DCI, the terminal may acquire I in the network configuration information MCS And rv (rv) id According to I MCS And rv (rv) id And determining a code word number corresponding to the transmission block corresponding to the transmission data, and then determining a scrambling sequence of the transmission data of each transmission point based on the code word number.
The transport blocks may be packedIncludes a first transport block and a second transport block. The terminal is according to I MCS And rv (rv) id When determining the codeword number corresponding to the transport block corresponding to the transmission data, the I of the first transport block can be obtained respectively MCS And rv (rv) id And acquiring I of the second transport block MCS And rv (rv) id . In case that the transmission data of at least two transmission points are scheduled by a plurality of PDCCHs, I corresponding to the first transmission block MCS And rv (rv) id When the preset condition is satisfied, it may be determined that the codeword number corresponding to the first transport block is 0. I corresponding to the second transmission block MCS And rv (rv) id And when the preset condition is met, determining that the code word number corresponding to the second transmission block is 1. Here, the preset condition may include: i MCS Equal to 26 and rv id And 1 is not true at the same time.
For example, in the case that the maxnrofcodewordsschedule bydci of the network configuration information is 2, the terminal may respectively obtain the I of the first transport block MCS And rv (rv) id I of acquiring second transport block MCS And rv (rv) id . For the first transport block, if the first transport block does not satisfy I MCS Equal to 26 and rv id Equal to 1, the codeword number corresponding to the first transport block is 0, so that equation c can be based init ＝n RNTI ·2 15 +q·2 14 +n ID A scrambling sequence initial value of the transmission data of the first transport block is determined, and then a scrambling sequence of the transmission data of the first transport block is determined from the scrambling sequence initial value. Wherein n is ID ∈{0,1,...,1023}，n ID May be equal to the higher layer parameter datascanmblingIdentityPDSCH, if higher layer parameters are not configured, n ID May be equal to the serving cell identity. n is n RNTI May be a radio network temporary identity (RNTI, radio Network Tempory Identity) associated with the PDSCH. For the second transport block, if the second transport block does not satisfy I MCS Equal to 26 and r vid Equal to 1, the codeword number corresponding to the second transport block is 1, so that equation c can be based init ＝n RNTI ·2 15 +q·2 14 +n ID Determining initial value of scrambling sequence of transmission data of second transmission block, then rootA scrambling sequence of the transmission data of the second transport block is determined from the scrambling sequence initial value.
In one possible implementation manner, when determining the scrambling sequence of the transmission data of each transmission point based on the network configuration information, if the terminal obtains the network configuration information through the received downlink control information DCI, the terminal may obtain preset field information corresponding to the transmission data of each transmission point in the network configuration information, for example, PDSCH scrambling ID in the DCI. The terminal can then determine the code word number corresponding to the transmission block of the transmission data according to the preset field information, and then determine the scrambling sequence of the transmission data of each transmission point according to the code word number.
For example, the terminal may determine the codeword number corresponding to the transport block for transmitting the data according to the value of the preset field information included in the DCI. For example, the preset field information may be PDSCH scrambling ID, which may be 1bit, and if PDSCH scrambling ID is 0, it may indicate that the codeword number corresponding to the transmission data scheduled by the PDCCH of the DCI is 0; if PDSCH scrambling ID is 1, the codeword number corresponding to the transmission data of the PDCCH schedule indicating the DCI is 1. Then can be based on formula c init ＝n RNTI ·2 15 +q·2 14 +n ID And acquiring a scrambling sequence initial value of the transmission data scheduled by the PDCCH, and then determining the scrambling sequence of the transmission data according to the scrambling sequence initial value.
In one possible implementation manner, when determining the scrambling sequence of the transmission data of each transmission point based on the network configuration information, if the terminal obtains the network configuration information through the higher layer information, the terminal may obtain a control resource set identifier (CORESET ID, control Resource Set Identification) of the control resource set according to the network configuration information, then determine the codeword number of the PDCCH scheduling codeword corresponding to the CORESET ID according to the CORESET ID and the association relationship between the CORESET ID and the codeword number, and then determine the scrambling sequence of the transmission data of each transmission point according to the codeword number.
For example, when determining the codeword number of the PDCCH scheduling codeword corresponding to the CORESETID according to the CORESETID and the association relationship between the CORESETID and the codeword number, the terminal may determine the codeword number of the PDCCH scheduling codeword according to the following manner:
under the condition that CORESETID mod 2 is equal to 0, if a code word is scheduled by a PDCCH corresponding to CORESETID, the code word number corresponding to transmission data scheduled by the corresponding PDCCH is 0; if CORESETID mod 2 is equal to 1, if the PDCCH corresponding to CORESETID schedules transmission data of one codeword, the codeword number corresponding to the transmission data scheduled by the corresponding PDCCH is 1. Where mod represents a modulo operation.
After determining the codeword number of the PDCCH scheduling codeword in the above manner, the terminal can be based on formula c init ＝n RNTI ·2 15 +q·2 14 +n ID And acquiring a scrambling sequence initial value of the transmission data scheduled by the PDCCH, and then determining the scrambling sequence of the transmission data according to the scrambling sequence initial value.
In one possible implementation manner, when determining the scrambling sequence of the transmission data of each transmission point based on the network configuration information, the terminal may further obtain preset field information corresponding to the transmission data of each transmission point in the network configuration information, then determine a codeword number corresponding to a transmission block of the transmission data of each transmission point according to the preset field information corresponding to the transmission data of each transmission point, and then determine the scrambling sequence of the transmission data of each transmission point according to the codeword number.
For example, the terminal may obtain CORESET from the high-layer information, and may determine the codeword number of the PDCCH scheduling codeword associated with CORESET according to the preset field information of CORESET corresponding to CORESET id. For example, the preset field information may be a PDSCH scheduling ID, where the PDSCH scheduling ID is 1bit, and if PDSCH scrambling ID has a value of 0, it may indicate that the codeword number corresponding to the transmission data scheduled by the PDCCH associated with the CORESET is 0; if PDSCH scrambling ID is 1, the codeword number corresponding to the transmission data of the PDCCH schedule associated with the CORESET is 1.
The terminal determines the PDCC in the modeAfter the codeword number of the H-scheduled codeword, the formula c can be based on init ＝n RNTI ·2 15 +q·2 14 +n ID And acquiring a scrambling sequence initial value of the transmission data scheduled by the PDCCH, and then determining the scrambling sequence of the transmission data according to the scrambling sequence initial value.
After determining the scrambling sequence of the transmission data of each transmission point based on the network configuration information, the terminal may descramble the transmission data of each transmission point using the determined scrambling sequence. By the scrambling sequence determining method provided by the embodiment of the disclosure, the transmission data of each transmission point can correspond to different scrambling sequences, so that the interference of the transmission data between the transmission points can be reduced, and the capability of the terminal for processing the transmission data of multiple transmission points is enhanced.
It should be noted that, although the scrambling sequence determining method of the multiple transmission points is described above by taking the terminal receiving the transmission data of the multiple transmission points as an example, those skilled in the art will understand that the present disclosure should not be limited thereto. In fact, the user can flexibly set the application scenario of the scrambling sequence determining scheme of the multiple transmission points according to personal preference and/or actual application scenario, so long as the scrambling sequence determining scheme of the multiple transmission points provided by the embodiment of the disclosure is adopted.
