Description

Technical Field

[0002] Wireless communication technology has experienced rapid development in the past few decades, from the first generation of wireless communication systems based on analog communication systems, to 2G wireless communication systems represented by the global system for mobile communication (GSM), to 3G wireless communication systems represented by wideband code division multiple access (WCDMA), and then to 4G wireless communication systems such as long term evolution (LTE), which are now widely used in the world and have achieved great success. The services supported by wireless communication systems have also evolved from the initial voice and text messages to the current support for wireless high-speed data communications. At the same time, the number of wireless connections around the world is experiencing a continuous and rapid growth, and various new types of wireless services are also emerging, such as the Internet of Things and autonomous driving, which have put forward higher requirements for the next generation of wireless communication systems, that is, 5G systems.

[0003] User collaboration is one of the main features supported by the next generation communication system.

[0080] The following will be combined Figure 3-Figure 7 The uplink transmission method provided in the embodiment of the present application is specifically described.

[0081] Figure 3 A flow chart of an uplink transmission method provided in an embodiment of the present application. The uplink transmission method can be applied to Figure 1 The source terminal is shown communicating with the network device via the cooperating terminal.

[0082] like Figure 3 As shown, the uplink transmission method includes:

[0083] S301: The network device sends indication information to the source terminal and the cooperative terminal. Correspondingly, the source terminal and the cooperative terminal receive the indication information from the network device.

[0084] Among them, the indication information is used to indicate at least one time interval between the sidelink resource and the uplink resource in cooperative transmission. The sidelink resource is used for the source terminal to send data to the cooperative terminal, that is, for the cooperative terminal to receive data from the source terminal. The uplink resource is used for the cooperative terminal to send data to the network device, that is, for the network device to receive data from the cooperative terminal. It should be noted that the above uplink resource refers to the uplink resource associated with the sidelink resource, and "associated" means that both the uplink resource and the sidelink resource are the uplink resource and the sidelink resource used in the same uplink cooperative transmission.

[0085] In a possible design method, the time interval can be: the time interval between the time domain start position of the uplink resource and the time domain start position of the sidelink resource. Alternatively, optionally, the time interval is: the time interval between the time domain start position of the uplink resource and the time domain end position of the sidelink resource.

[0086] In a possible design method, the indication information is further used to indicate that the product of the period and the number of repetitions of the sidelink resource is equal to the product of the period and the number of repetitions of the uplink resource. That is to say, when the number of repetitions is greater than 1, the data can be sent multiple times on the uplink resource and the sidelink resource.

[0087] This will be described in detail through several examples below.

[0088] Exemplarily, Figure 4 is a schematic diagram of the time interval between the sidelink resource and the uplink resource provided by the embodiment of the present application Figure 1 . As Figure 4 shown, the sidelink resource SL1 and the uplink resources UL1-UL3 are all resources used for one uplink cooperative transmission, and UL1-UL3 are located after SL1 in the time domain. Among them, the time intervals between the time domain start positions of UL1-UL3 and the time domain start position of SL1 are t1-t3 respectively, and t1 < t2 < t3, which can be used for the cooperative terminal to forward the data received from the source terminal on SL1 to the network device.

[0089] Exemplarily, Figure 5 is a schematic diagram of the time interval between the sidelink resource and the uplink resource provided by the embodiment of the present application Figure 2 . As Figure 5As shown, the sidelink resource SL1 and the uplink resources UL1 - UL3 are all resources for one uplink cooperative transmission, and UL1 - UL3 are located after SL1 in the time domain. Among them, L is the duration of SL1, and the unit can be symbols, time slots, sub - frames, etc. The time intervals between the time domain start positions of UL1 - UL3 and the time domain end position of SL1 are t1 - t3 respectively, and t1 < t2 < t3. This can be used for the cooperative terminal to forward the data received from the source terminal on SL1 to the network device.

[0090] Exemplarily, Figure 6 is a schematic diagram of the time interval between the sidelink resource and the uplink resources provided by the embodiments of this application Figure 3 , and is used for re - transmission in uplink cooperative transmission. As Figure 6 shown, UL1 - UL3 are located after SL1 in the time domain, and the sidelink resource SL1 is used for K re - transmissions of a data packet on the sidelink. The transmission period of each transmission is P, and K * P is a scheduling period; the uplink resources UL1 - UL3 are respectively used to re - forward the data packet to the network device K1 times, K2 times, and K3 times on the uplink. The transmission periods of each re - forward are P1, P2, and P3 respectively, and K1 * P1, K2 * P2, and K3 * P3 are the scheduling periods of UL1 - UL3 respectively. For the convenience of scheduling in uplink cooperative transmission, the scheduling period of the sidelink resource is usually the same as the scheduling periods of each uplink resource, that is, K * P = K1 * P1 = K2 * P2 = K3 * P3. Assuming that the time domain start position of the uplink resource is the time domain start position of the first transmission period, and the time domain start position of the sidelink resource is the time domain start position of the first transmission period, the time intervals between the time domain start positions of UL1 - UL3 and the time domain start position of SL1 are t1 - t3 respectively, and t1 < t2 < t3.

[0091] Exemplarily, Figure 7 is a schematic diagram of the time interval between the sidelink resource and the uplink resources provided by the embodiments of this application Figure 3 , and is used for re - transmission in uplink cooperative transmission. As Figure 7As shown, UL1 - UL3 are located after SL1 in the time domain. The sidelink resource SL1 is used for K - time repeated transmission of a data packet on the sidelink, and the transmission period for each transmission is P. K*P is a scheduling period. The uplink resources UL1 - UL3 are respectively used for repeating and forwarding the data packet to the network device K1 times, K2 times, and K3 times on the uplink, and the transmission periods for each forwarding are P1, P2, and P3 respectively. K1*P1, K2*P2, and K3*P3 are respectively a scheduling period of UL1 - UL3. For the convenience of scheduling in uplink cooperative transmission, the scheduling period of the sidelink resource is usually the same as that of each uplink resource, that is, K*P = K1*P1 = K2*P2 = K3*P3. Assuming that the time - domain starting position of the uplink resource is the time - domain starting position of the first transmission period, and the time - domain starting position and the time - domain ending position of the sidelink resource are respectively the time - domain starting position of the first transmission period and the time - domain ending position of the last transmission period, the time intervals between the time - domain starting positions of UL1 - UL3 and the time - domain ending position of SL1 are t1 - t3 respectively, and t1 < t2 < t3. And the duration L of SL1 is the time length from the time - domain starting position of SL1 to the time - domain ending position of SL1. It should be noted that for Figure 6 and Figure 7 the repeated transmission shown, whether it is the sidelink or the uplink, the resources occupied by two adjacent repeated transmissions can be continuous or discontinuous. The embodiments of the present application do not make any limitations in this regard.

[0092] It should be noted that Figure 4-Figure 7 only one sidelink resource SL1 and three corresponding uplink resources UL1 - UL3 are drawn, which can be used for uplink cooperative transmission of a data packet, such as 1 TB. It is easy to understand that the network device can also configure multiple uplink cooperative transmission resources, which can be used for uplink cooperative transmission of multiple data packets, such as multiple TBs. Among them, each uplink cooperative transmission resource can include a sidelink resource and one or more uplink resources corresponding to the sidelink resource, and the configurations in different uplink cooperative transmission resources can be the same or different. The embodiments of the present application do not make any limitations in this regard.

[0093] S302, the source terminal sends the first data to the cooperative terminal on the first sidelink resource. Correspondingly, the cooperative terminal receives the first data from the source terminal on the first sidelink resource.

[0094] Exemplarily, referring to Figure 4-Figure 7 , the source terminal can send the first data to the cooperative terminal on the sidelink resource SL1. Correspondingly, the cooperative terminal can receive the first data from the source terminal on the sidelink resource SL1.

[0095] S303. The cooperating terminal determines a first uplink resource from the uplink resource pool according to the first sidelink resource and the indication information.

[0096] In a possible design method, for the above S303, where the cooperating terminal determines a first uplink resource from the uplink resource pool according to the first sidelink resource and the indication information, it may include:

[0097] The cooperating terminal determines a first uplink resource from the uplink resource pool according to the first sidelink resource and the first time interval.

[0098] Wherein, the first time interval is one of at least one time interval. The time interval between the first uplink resource and the first sidelink resource is greater than or equal to the first time interval, and the first uplink resource is the uplink resource in the uplink resource pool with the smallest time deviation between the time interval between it and the first sidelink resource and the first time interval. The uplink resource is an available uplink resource in the uplink resource pool whose time interval with the first sidelink resource is greater than or equal to the first time interval.

[0099] Exemplarily, as Figure 4-Figure 7 shown, the first time interval can be selected from the time intervals t1 - t3 between 3 uplink resources UL1 - UL3 and the sidelink resource SL1. Optionally, the first time interval can be the minimum value t1 among t1 - t3, so as to reduce the forwarding duration as much as possible, thereby reducing the overall delay of the uplink cooperative transmission.

[0100] Optionally, the first time interval can be the time interval that is greater than or equal to the first processing duration and has the smallest value among at least one time interval, so as to ensure that the cooperating terminal has sufficient time to complete processing such as receiving, decoding, and forwarding. Wherein, the first processing duration is the processing time required for the cooperating terminal to receive the first data and then send the first data to the network device, such as Figure 4-Figure 7 the T in Figure 4-Figure 7 . Exemplarily, referring to

[0101] Assume that T > t1 and T < t2, then the first time interval is t2, and the first uplink resource is UL2.

[0102] Exemplarily, the first processing duration is specifically the processing time required for the cooperative terminal to simply forward the first data to the network device. Or, optionally, the first processing duration is specifically the processing time required for the cooperative terminal to decode and forward the first data to the network device. Herein, simple forwarding means forwarding without decoding, such as using symbols, slots, subframes, etc. as units, and directly mapping the modulation symbol received on SL1 to the time-frequency resources on the UL to send it to the network device. Decoding forwarding refers to demodulating and decoding the signal received on the SL to recover the data before encoding, and then re-encoding and modulating the data before encoding, and mapping it to the time-frequency resources on the UL to send it to the network device. Decoding forwarding can include forwarding according to transmission block (TB), forwarding according to code block (CB), etc. It should be understood that for decoding and forwarding, the coding and modulation scheme (MCS) used on the UL and the coding and modulation scheme used on the SL can be the same or different. For example, a higher code rate MCS (compressed forwarding) or a lower code rate MCS (amplified forwarding) can be used on the UL. The specific determination can be based on the channel conditions of the SL and the UL when uplink collaborative transmission occurs, and the embodiments of the present application are not limited to this.

[0103] S304: The cooperative terminal sends first data to the network device on the first uplink resource. Correspondingly, the network device receives the first data from the cooperative terminal on the first uplink resource according to at least one time interval.

[0104] It should be noted that before the uplink cooperative transmission starts, the network device also needs to send the configuration information of the sidelink resource or the uplink resource to the source terminal and the cooperative terminal. Therefore, in a possible design method, Figure 3 The uplink transmission method shown may also include the following steps:

[0105] The network device sends control information to the source terminal and the cooperative terminal. Correspondingly, the source terminal and the cooperative terminal receive the control information from the network device. The control information is used to indicate the resource configuration of the sideline resource pool including the first sideline resource. Exemplarily, the control information may include the time domain starting position and the time domain ending position of the first sideline resource. Alternatively, the control information may include the time domain starting position and the transmission duration of the first sideline resource.

[0106] In the embodiment of the present application, the time domain starting position of each uplink resource can be calculated according to the control information and at least one time interval. Figure 4-Figure 7 Take UL2 in Figure 1 as an example.

[0107] For example, Figure 4 and Figure 6 As shown, the time domain starting position of UL2 is:

[0108] t ul2_start =t sl1_start +t2,

[0109] Among them, t ul2_start is the time domain starting position of UL2, t sl1_start is the time domain starting position of SL1, and t2 is the time interval between the time domain starting position of UL2 and the time domain starting position of SL1.

[0110] For example, Figure 5 and Figure 7 As shown, the time domain starting position of UL2 can be:

[0111] t ul2_start =t sl1_end +t2,

[0112] Among them, t ul2_start is the time domain starting position of UL2, t sl1_end is the time domain end position of SL1, and t2 is the time interval between the time domain start position of UL2 and the time domain end position of SL1.

[0113] For example, Figure 5 and Figure 7 As shown, the time domain starting position of UL2 can also be:

[0114] t ul2_start =t sl1_start +L+t2,

[0115] Among them, t ul2_start is the time domain starting position of UL2, t sl1_end is the time domain end position of SL1, t2 is the time interval between the time domain start position of UL2 and the time domain end position of SL1, and L is the transmission duration of SL1.

[0116] The uplink transmission method provided in the embodiment of the present application is such that the cooperative terminal can select, according to the indication information sent by the network device, a first uplink resource for forwarding the first data from the source terminal to the network device from a plurality of uplink resources having different time intervals with the sidelink resources, such as selecting an uplink resource that meets the forwarding time requirement and has the smallest time interval, so as to reduce the forwarding delay, thereby reducing the uplink cooperative transmission delay and improving communication efficiency.
