[0002] Contention resolution diversity slotted ALOHA (CRDSA) technology is a technology for reducing the uplink collision probability of a contention channel and improving the uplink capacity. A terminal generates multiple uplink transmissions by copying an uplink transmission, and then transmits the multiple uplink transmissions at different times. Once the network successfully receives any one of the uplink transmissions, the network can perform interference cancellation on other reception positions based on the received uplink transmission, and thus can parse other uplink transmissions that collide with the uplink transmission at the other reception positions.

[0003] In order to perform interference cancellation, the network device needs to know the transmission time of each of the multiple uplink transmissions.

[0169] In the field of communication technology, contention resolution diversity slotted ALOHA (CRDSA) technology is a technology for reducing the uplink collision probability of a contention channel and improving the uplink capacity. A terminal generates a copy packet by copying an uplink transmission, and then transmits the uplink transmission and the copy packet at different times. The network receives any one of the packets and succeeds in receiving, thereby reducing the collision failure probability.

[0170] In some embodiments, because the terminal transmits at least two uplink transmissions that are the same, the collision probability is increased to a certain extent, and therefore interference cancellation technology needs to be used. The process is described below in conjunction with FIG. 1B. FIG. 1B is a schematic diagram of uplink transmissions received by a network device. For example, a terminal transmits two uplink transmissions PK3, one of which, PK3, does not collide, and the network device can correctly parse. The other PK3 collides with an uplink transmission PK2 transmitted by another terminal. Then the network device can use the correctly parsed PK3 to perform interference cancellation on the position of the other PK3, so that the network device can correctly parse the uplink transmission PK2 transmitted by the other terminal. Then the network device can use the parsed PK2 to perform interference cancellation on the position of the other PK2, parse PK1, and so on, until all uplink transmissions that can be parsed are parsed, such as PK4, PK5, and PK6 in the figure.

[0171] In the present disclosure, in order to perform interference cancellation, the network device needs to know the time information of each copy packet of the uplink transmission, so as to determine the position of the copy packet and perform interference cancellation. To this end, the embodiments of the present disclosure provide an information transmission method, in which a terminal transmits time information at the same time as transmitting an uplink transmission, to assist the network device in determining the transmission time of each uplink transmission, so that the terminal can perform interference cancellation on multiple uplink transmissions received at the same time.

[0172] The information transmission method and device provided by the present disclosure are described in detail below in conjunction with the accompanying drawings.

[0173] FIG. 2 is an interaction diagram of an information transmission method according to an embodiment of the present disclosure. As shown in FIG. 2, the embodiments of the present disclosure relate to an information transmission method, and the method includes the following steps.

[0174] In step S2101, the terminal 101 transmits a MAC PDU containing a first uplink transmission to the network device 102, wherein the MAC PDU includes a MAC CE carrying time information.

[0175] In some embodiments, the time information is used to indicate the transmission time of a second uplink transmission, and the first uplink transmission and the second uplink transmission carry the same data.

[0176] In some embodiments, the number of the second uplink transmissions can be one or more.

[0177] In some embodiments, the terminal 101 can determine the total number of the first uplink transmissions and the second uplink transmissions according to an indication of the network device.

[0178] In some embodiments, the terminal 101 can also determine the total number of the first uplink transmissions and the second uplink transmissions according to a network status. For example, if the network status is poor, in order to maximize the probability of successful reception of the uplink transmission, the terminal 101 can determine a larger total number; and if the network status is good, the terminal 101 can determine a smaller total number, and the like, which are not limited in the present disclosure.

[0179] In some embodiments, the terminal 101 can send the determined total number to the network device 102.

[0180] In some embodiments, the terminal 101 can also not send the total number to the network device 102, but implicitly indicate the total number through time information.

[0181] In some embodiments, the first uplink transmission is any one of a plurality of uplink transmissions carrying the same data.

[0182] In some embodiments, the terminal 101 is a terrestrial network terminal or a non-terrestrial network terminal.

[0183] In some embodiments, the terms “terrestrial network”, “TN”, “Terrestrial Network” and the like can be replaced with each other.

[0186] In some embodiments, the terms “MAC CE”, “Media Access Control Address Control Element”, “media access control control” and the like can be replaced with each other.

[0187] In the embodiments of the present disclosure, the terminal 101 sends time information to the network device 102 while sending the first uplink transmission, so that the network device 102 can accurately determine the time domain position occupied by the second uplink transmission, and then can perform interference cancellation on the uplink transmission received in other time domain positions based on the received first uplink transmission, thereby improving the uplink capacity, avoiding the probability of uplink transmission reception failure due to uplink transmission collision, and improving the performance and reliability of the communication system.

[0188] In some embodiments, the first uplink transmission described above can be the first uplink message sent by the terminal 101 to the network device 102 when the terminal 101 interacts with the network device 102. For example, it can be the first message (Msg1) in the four-step random access process, or the first message (MsgA) in the two-step random access process, or the first message in the EDT, SDT, and the like.

[0189] In some embodiments, the terms “EDT”, “early data transmission”, “early data transmission” and the like can be replaced with each other.

[0190] In some embodiments, the terms “SDT”, “small data transmission”, “small data transmission” and the like can be replaced with each other.

[0191] In some embodiments, the first uplink message can also be the first message of the LTE EDT enhancement. Since the first message of the LTE EDT enhancement is sent through the configured contention resource, the difference between it and EDT is that msg1 and Msg2 of EDT are omitted, and msg3 is sent directly, that is, the first uplink message in the embodiments of the present disclosure can also be Msg3 of the LTE EDT enhancement.

[0192] In some embodiments, the terms “LTE”, “Long Term Evolution”, “Long Term Evolution” and the like can be replaced with each other.

[0193] In some embodiments, the terms “Msg1”, “first message”, “message 1”, “first message in four-step random access” and the like can be replaced with each other.

[0195] In some embodiments, the terms “Msg3”, “third message”, “message 3”, “third message in four-step random access” and the like can be replaced with each other.

[0196] In some embodiments, the priority of the MAC CE is the same as the priority of the data from the uplink common control channel.

[0197] In some embodiments, the terms "data from UL-CCCH", "data from uplink Common Control Channel", and the like can be replaced with each other.

[0198] In the embodiments of the present disclosure, by using the MAC CE with higher priority to carry the time information, the reliability and the probability of being received of the transmission of the time information are improved, which provides conditions for the network device 102 to perform reliable interference cancellation.

[0199] In some embodiments, the terminal 101 can sequentially send each uplink transmission to the network device 102 through a MAC PDU. In each MAC PDU, the time information carried by the MAC CE of the time information can be the same or different. That is, each MAC CE can carry the time information of all uplink transmissions, or each MAC CE can only carry the time information of other uplink transmissions, which is not limited in the present disclosure.

[0200] In some embodiments, the time information is one or more of the following: the sending time information of the other uplink transmissions in the plurality of uplink transmissions except the first uplink transmission; the sending time information of each uplink transmission in the plurality of uplink transmissions.

[0201] In some embodiments, if the time information is the sending time information of the other uplink transmissions in the plurality of uplink transmissions except the first uplink transmission, the time information only indicates the sending time of the other uplink transmissions in the plurality of uplink transmissions except the first uplink transmission.

[0202] In some embodiments, if the time information is the sending time information of each uplink transmission in the plurality of uplink transmissions, the time information can indicate the sending time of each uplink transmission (including the current uplink transmission) in the plurality of uplink transmissions.

[0203] In some embodiments, the sending time information of the other uplink transmission can be the specific sending time of the other uplink transmission. Alternatively, it can be the relative time information of the sending time of the other uplink transmission relative to the first uplink transmission, or the relative time information of the other uplink transmission relative to the current uplink transmission.

[0204] In some embodiments, the time information of the other uplink transmission is relative time information of the other uplink transmission relative to the first uplink transmission, the first uplink transmission being a first transmitted uplink transmission among the multiple uplink transmissions; or, the time information of the other uplink transmission is relative time information of the other uplink transmission relative to the first uplink transmission.

[0205] In the embodiments of the present disclosure, the time information transmitted simultaneously with each uplink transmission can contain the transmission time of the other uplink transmission, so as to minimize the transmission resources occupied by the time information, or can also contain the transmission time of the current uplink transmission, so that the network device can more accurately determine the transmission time of each uplink transmission.

[0206] In some embodiments, the unit of the time information can be second, millisecond, subframe, slot or OFDM symbol.

[0207] In some embodiments, the terms of “OFDM”, “Orthogonal Frequency Division Multiplexing” and the like can be replaced with each other.

[0208] In some embodiments, the time information includes one or more of the following: a subframe index corresponding to the second uplink transmission;

[0209] a subframe index difference between the subframe index corresponding to the second uplink transmission and the subframe index corresponding to the first uplink transmission;

[0214] a least significant bit index of a system frame number corresponding to the second uplink transmission.

[0215] In some embodiments, the terms of “subframe index” and the like can be replaced with each other.

[0216] In some embodiments, the terms of “slot index” and the like can be replaced with each other.

[0217] In some embodiments, the terms "orthogonal frequency division multiplexing symbol index", "OFDM index" and the like can be replaced by each other.

[0218] In some embodiments, the terms "least significant bit(s) of system frame number index", "LSB(s) of SFN index", "Least Significant Bit(s) of System Frame Number" and the like can be replaced by each other.

[0219] In some embodiments, the number of the second uplink transmissions is greater than 1, and the time information can include multiple subframe indexes, slot indexes and / or OFDM indexes, etc. The index types corresponding to different second uplink transmissions can be the same or different.

[0220] For example, the number of the second uplink transmissions is 2, and the time information can include different subframe indexes corresponding to the two second uplink transmissions, or can include different slot indexes corresponding to the two second uplink transmissions, or can include a subframe index corresponding to one second uplink transmission and a slot index corresponding to the other second uplink transmission, etc. The present disclosure does not limit this.

[0221] In the embodiments of the present disclosure, the time information of the second uplink transmission can be indicated by time indexes of multiple granularities, which improves the flexibility and diversity of the indication of the time information.

[0222] In some embodiments, the time information can also be used to indicate time range information corresponding to the transmission time of the second uplink transmission.

[0223] In some embodiments, the time information can also include one or more of the following: a subframe index boundary value corresponding to the second uplink transmission; a slot index boundary value corresponding to the second uplink transmission; and an orthogonal frequency division multiplexing symbol index boundary value corresponding to the second uplink transmission.

[0224] For example, the time information includes slot index#1 and slot index#2, and the network device 102 can determine that the second uplink transmission will be transmitted between slot index#1 and slot index#2, so that the network device 102 can listen to and receive the second uplink transmission in this period.

[0225] In some embodiments, the number of the second uplink transmissions is multiple, and the time information can include a time range corresponding to each uplink transmission, and the granularity of the time range corresponding to different uplink transmissions can be the same or different. For example, the time information includes two time range information corresponding to two second uplink transmissions respectively, one of which is slot index #1 and slot index #2, and the other is OFDM index #1 and OFDM index #2.

[0226] In some embodiments, correspondingly, in step S2103, the network device also performs interference cancellation in the time period corresponding to the time range information, and the interference is the second uplink transmission.

[0227] In some embodiments, the terminal 101 can send the first uplink transmission and the time information to the network device 102 through an RRC message.

[0228] In some embodiments, the terms of "RRC", "Radio Resource Control", "Radio Resource Control" and the like can be replaced with each other.

[0229] In some embodiments, the RRC message is any one of the following: RRC early data request message, connection resume request message.

[0230] In some embodiments, the terms of "RRC early data request message", "RRCEarlyDataRequest" and the like can be replaced with each other.

[0231] In some embodiments, the terms of "connection resume request message", "RRCConnectionResumeRequest" and the like can be replaced with each other.

[0232] In the embodiments of the present disclosure, the uplink transmission and the time information are sent by multiplexing the existing RRC message, which provides conditions for improving the success rate of the transmission of the uplink transmission and the time information.

[0233] In some embodiments, the network device 102 receives the first uplink transmission and the time information sent by the terminal 101.

[0234] In some embodiments, the network device 102 receives a medium access control (MAC) protocol data unit (PDU) containing the first uplink transmission sent by the terminal 101, wherein the MAC PDU includes a MAC CE carrying the time information.

[0235] In some embodiments, the terminal 101 can determine the above-mentioned time information according to a preset time interval, or determine the above-mentioned time information according to the duration of multiple same uplink transmissions.

[0236] In some embodiments, the terminal 101 can determine the time interval or the duration according to a protocol agreement.

[0237] In some embodiments, the terminal 101 can also determine the time interval or the duration according to an indication of the network device 102.

[0238] At step S2102, the network device 102 determines the transmission time of the second uplink transmission according to the time information.

[0239] In some embodiments, the first uplink transmission received by the network device 102 can be the first uplink transmission of a plurality of same uplink transmissions, or can be any one of the plurality of same uplink transmissions, which is not limited in the present disclosure.

[0240] In some embodiments, if the MAC CE contains time information of other uplink transmissions in addition to the first uplink transmission, the network device 102 can determine the transmission time of the other uplink transmissions based on the time information carried by the MAC CE in the MAC PDU after receiving the MAC PDU containing the first uplink transmission.

[0241] In some embodiments, if the MAC CE contains time information of each of a plurality of uplink transmissions, the network device 102 can determine the transmission time of the first uplink transmission and other second uplink transmissions based on the time information.

[0242] At step S2103, the network device 102 performs interference cancellation on the third uplink transmission based on the first uplink transmission.

[0243] In some embodiments, the third uplink transmission is received by the network device 102 within the transmission time of the second uplink transmission of the network device 102.

[0244] Referring to FIG. 1B, if the network device 102 currently receives the uplink transmission PK3 (such as one PK3 in FIG. 1B that does not collide with any uplink transmission) sent by the terminal 1, the network device 102 obtains the transmission time of another PK3 packet according to the MAC CE. Then, the network device 102 can perform interference cancellation on the newly received uplink transmission based on the previously received PK3 after receiving the uplink transmission corresponding to the transmission time of the other PK3 packet, so as to obtain the transmission time of the uplink transmission PK2 and other PK2 sent by the terminal 2. Then, the network device 102 can perform interference cancellation on the uplink transmission received within the transmission time of the other PK2 based on the determined PK2, and so on, so as to accurately obtain all the uplink transmissions.

[0245] In some embodiments, if the time information is contained in the uplink transmission, and the time information of other uplink transmission than the first uplink transmission is contained in the time information, the network device 102 needs to replace the time information in the received first uplink transmission with the time information of the first uplink transmission before performing interference cancellation on the other uplink transmission based on the first uplink transmission.

[0246] For example, if the time information of the uplink transmission B is contained in the uplink transmission A, the time information of the uplink transmission A is also contained in the uplink transmission B. Therefore, in order to cancel the uplink transmission B, the network device needs to replace the time information in the uplink transmission A with the time information in the uplink transmission B (that is, replace the time information of the uplink transmission A) so that the uplink transmission A is the same as the uplink transmission B. At this time, the uplink transmission A can be used to cancel the uplink transmission B to obtain other uplink transmissions received at the same time as the uplink transmission B.

[0247] The communication method related to the embodiments of the present disclosure can include at least one of steps S2101-S2103. For example, step 2101 can be implemented as an independent embodiment, step 2102 can be implemented as an independent embodiment, step 2102+2103 can be implemented as an independent embodiment, and the like, but is not limited thereto.

[0248] In the present embodiment or example, each step can be independent, arbitrarily combined or exchanged in order, the optional mode or optional example can be arbitrarily combined, and can be arbitrarily combined with any step of other embodiments or other examples.
