Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to an indication and reception method for multiple access codewords, a network device, and a terminal.
Background
In the 4G system, an SC-FDMA (Single-carrier Frequency-division Multiple Access) system is used in an uplink, and an OFDMA (Orthogonal Frequency division Multiple Access) system is used in a downlink.
Although the MUST research project of 4G L TE-pro researches on non-orthogonal transmission, the multi-access method aims at only downlink transmission and adopts a power domain non-orthogonal mode.
In the early SI research of 3GPP 5G NR, more novel non-orthogonal multiple access methods were proposed, such as: SCMA (Sparse Code Multiple Access), PDMA (Pattern Division Multiple Access), IDMA (interlace Division Multiple Access), NOCA (Non-orthogonal coded Multiple Access), and the like. But limited by the time schedule, in the first release of 3GPP 5G NR, a non-orthogonal multiple access scheme is not introduced. But for further evolution of 5G NR, non-orthogonal multiple access is again proposed by the 3GPP standardization schedule.
The current 5G NR standard has introduced a transmission mode with scheduled Scheduling, in which a base station is configured in advance for transmitting related parameters through RRC (Radio Resource Control) signaling, and a user transmits data on a pre-scheduled time-frequency Resource directly or triggered by L1 signals using preconfigured transmission parameters without sending Scheduling Request (SR) and waiting for dynamic Scheduling signaling, thereby reducing data transmission delay and Control signaling overhead required for dynamic Scheduling.
However, the above pre-configuration has the following potential problems: (1) different multiple access code words are preconfigured for different users, a larger multiple access code word set is objectively needed, and the blind detection complexity is very high; (2) the user randomly selects the multiple access codeword for his own use, but there is a risk of codeword collision. (3) Not applicable to grant-based (scheduling based) transmission scenarios.

While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
As shown in fig. 1, an embodiment of the present invention provides a method for indicating multiple access codewords, which is applied to a network device, and the method includes:
The indication information of whether the multiple access code word used by the terminal collides with the code word used by other terminals is obtained by the network device through activation detection of the terminal. The network device here may be a base station or the like.
In a specific embodiment of the present invention, step 11 may send the indication information to the terminal through a Downlink Control Information (DCI) signaling or a Physical Downlink Shared Channel (PDSCH).
When the indication information is sent to a terminal through a Downlink Control Information (DCI) signaling, for example, at least one bit is added to the DCI signaling, where the at least one bit represents the indication information; and sending the DCI signaling to the terminal.
In a preferred embodiment, 1bit is added to the DCI, where the bit may be represented by Identifier for MA codebook collision, and is used to indicate whether a multiple access codeword used by the terminal collides with a codeword used by another terminal, if a codeword collision occurs, the Identifier for MA codebook collision is 1/0, otherwise, the Identifier for MA codebook collision is 0/1. Of course, the embodiments of the present invention are not limited to being represented by bits, and may be represented by dedicated field information, for example.
Further, the method for indicating multiple access code words of the present invention may further include:
and step 12, indicating the multiple access code word index used by the terminal through a Physical Downlink Shared Channel (PDSCH).
Specifically, the multiple access codeword index used by the terminal may be indicated through media access control-control element (MAC-CE) signaling carried on the PDSCH.
In specific implementation, 1bit is added to the DCI, where the bit may be represented by Identifier for MA codebook collision, and is used to indicate whether a multiple access codeword used by the terminal collides with a codeword used by another terminal, if the codeword collides, the Identifier for MA codebook collision is 1/0, otherwise, the Identifier for MA codebook collision is 0/1; and indicates the multiple access code word used by the terminal through MAC-CE signaling carried on the PDSCH.
In another embodiment of the present invention, step 11 may send the indication information to a terminal through a Downlink Control Information (DCI) signaling, and indicate, through the DCI signaling, a multiple access codeword index used by the terminal.
The DCI signaling comprises at least two bits, wherein a first part of the at least two bits represents the indication information, and a second part of the at least two bits represents the multiple access codeword index;

the second part of bits may also be the remaining bits of the at least two bits except the first part of bits.
In the embodiment of the present invention, a relationship between a first part of bits and a second part of bits is not limited, and any bit or any combination of any bits in at least two bits in the DCI signaling may represent the indication information, may also represent a multiple access codeword index, and may also represent the indication information and the multiple access codeword index at the same time, that is, the first part of bits and the second part of bits may represent the indication information and the multiple access codeword index independently, or may represent the indication information and the multiple access codeword index in combination; of course, in at least two bits of the DCI signaling, in addition to the first part of bits and the second part of bits, if there are remaining bits, the remaining bits may also be used to represent other information.
In a specific implementation, for example, 3 bits are added to DCI, where the first bit may be represented by Identifier for MA codebook collision, and is used to indicate whether a multiple access codeword used by the terminal collides with a codeword used by another terminal, if so, the Identifier for MA codebook collision is 1/0, otherwise, the Identifier for MA codebook collision is 0/1; the remaining 2 bits indicate the multiple access codeword index used by the terminal.
The following describes the implementation process of the above embodiment with reference to specific implementation examples:
when the multiple access code word used by the terminal collides with the code words of other terminals, the base station side obtains which multiple access code words used by the users have collided by carrying out activation detection on the terminal.
The base station indicates the code word collision identifier in the DCI signaling of the terminal with the code word collision as follows: "1", for example: identity for multicodebook collision 1.
In order to avoid that the collided users continue to use the same multiple access code word during the subsequent data transmission, the base station indicates the multiple access code word used during the subsequent data transmission of the terminal through the MAC-CE signaling carried by the PDSCH or indicates the multiple access code word used during the subsequent data transmission of the terminal through the DCI signaling.
And the terminal changes the multiple access code word used for next data transmission and transmits the data by receiving the DCI signaling and the MAC-CE signaling in the PDSCH.
