Generally, conventional Communication systems support a limited number of connections and are easy to implement, however, with the development of Communication technology, mobile Communication systems will support not only conventional Communication, but also, for example, Device-to-Device (D2D) Communication, Machine-to-Machine (M2M) Communication, Machine Type Communication (MTC), and Vehicle-to-Vehicle (V2V) Communication, and the embodiments of the present application can also be applied to these Communication systems.

Optionally, the communication system in the embodiment of the present application may be applied to a Carrier Aggregation (CA) scenario, may also be applied to a Dual Connectivity (DC) scenario, and may also be applied to an independent (SA) networking scenario.

The frequency spectrum of the application is not limited in the embodiment of the present application. For example, the embodiments of the present application may be applied to a licensed spectrum and may also be applied to an unlicensed spectrum.

Referring to fig. 1, fig. 1 is a schematic diagram of a communication system architecture provided in an embodiment of the present application, where the communication system includes a network device and a terminal device. As shown in fig. 1, a network device may communicate with a terminal device. The communication system may be a 5G communication system (e.g., a New Radio (NR)), a communication system in which multiple communication technologies are merged (e.g., a communication system in which an LTE technology and an NR technology are merged), or a communication system evolved later. The form and number of the network devices and the terminal devices shown in fig. 1 are only for example and do not constitute a limitation to the embodiments of the present application.

The terminal equipment in the application is equipment with a wireless communication function, can be deployed on land and comprises an indoor or outdoor, a handheld, a wearable or a vehicle-mounted terminal; can also be deployed on the water surface (such as a ship and the like); and may also be deployed in the air (e.g., airplanes, balloons, satellites, etc.). The terminal device may be a mobile phone (mobile phone), a tablet computer (pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in remote medical (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in smart home (smart home), and the like. The terminal device may also be a handheld device with wireless communication capabilities, a vehicle mounted device, a wearable device, a computer device or other processing device connected to a wireless modem, etc. The terminal devices in different networks may be called different names, for example: a terminal device, an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent or user equipment, a cellular telephone, a cordless telephone, a Session Initiation Protocol (SIP) telephone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a terminal device in a 5G network or a future evolution network, etc.

The network device in the present application is a device deployed in a radio access network to provide a wireless communication function. For example, the Network device may be a Radio Access Network (RAN) device on an Access Network side in a cellular Network, and the RAN device is a device for accessing a terminal device to a wireless Network, and includes but is not limited to: evolved Node B (eNB), Radio Network Controller (RNC), Node B (NB), Base Station Controller (BSC), Base Transceiver Station (BTS), Home Base Station (e.g., Home evolved Node B, or Home Node B, HNB), baseband Unit (BBU), Management Entity (Mobility Management Entity, MME); for another example, the Network device may also be a node device in a Wireless Local Area Network (WLAN), such as an Access Controller (AC), a gateway, or a WIFI Access Point (AP); for another example, the network device may also be a transmission node or a transmission reception point (TRP or TP) in the NR system.

Unlicensed spectrum is a nationally and regionally divided spectrum available for communication by radio devices, which is generally considered a shared spectrum, i.e., a spectrum that can be used by communication devices in different communication systems as long as the regulatory requirements set by the country or region on the spectrum are met, without requiring a proprietary spectrum license to be applied to the government.

In order for various communication systems using unlicensed spectrum for wireless communication to coexist friendly on the spectrum, some countries or regions stipulate regulatory requirements that must be met using unlicensed spectrum. For example, the communication device follows the principle of "Listen Before Talk (LBT)", that is, before the communication device performs signal transmission on a channel of an unlicensed spectrum, it needs to perform channel sensing first, and only when the channel sensing result is that the channel is idle, the communication device can perform signal transmission; if the channel sensing result of the communication device on the channel of the unlicensed spectrum is that the channel is busy, the communication device cannot transmit signals. In order to ensure fairness, in one transmission, the duration of signal transmission by the communication device using the Channel of the unlicensed spectrum cannot exceed the Maximum Channel Occupancy Time (MCOT).

In NR systems, CG resources may be semi-statically configured through higher layer signaling. Two specific implementation schemes are provided:

type 1: the actual uplink grant may be obtained through Radio Resource Control (RRC) signaling;

type 2: the actual uplink grant can be obtained through a Physical Downlink Control Channel (PDCCH) scrambled by the CS-RNTI.

In the NR system, PUSCH mapping includes two types, Type a and Type B, in which a reference position l of a symbol is different from a position l0 of a first DMRS symbol.

For PUSCH mapping Type a: in the absence of frequency domain hopping, l is defined relative to the start of the time slot; in the case of frequency domain hopping, l is defined relative to the start after each hop. l0 is configured for higher layer signaling and takes the value of either sign 2 or sign 3.

For PUSCH mapping Type B: in the absence of frequency domain hopping,/, is defined relative to the start of scheduled PUSCH resources; in the case of frequency domain hopping, l is defined relative to the start after each hop. l0 ═ 0.

The value ranges of the starting symbol S and the length L of the PUSCH under the PUSCH mapping Type a and Type B are shown in table 1 below. As can be seen from table 1, Type a always starts from 0, and the scheduled PUSCH length is 4 to 14 symbols; type B may start from any one symbol within one slot, and the length of the scheduled PUSCH is any length.

TABLE 1

Referring to fig. 2A, fig. 2A is a schematic flow chart of a data transmission method according to an embodiment of the present application, which includes at least some of the following contents:

step 201: the network equipment sends first indication information to the terminal equipment; the terminal equipment receives first indication information of the network equipment.

Step 202: and the terminal equipment determines a first pre-configuration authorization uplink resource based on the first indication information, wherein the first pre-configuration authorization uplink resource occupies part or all of resources in at least one time slot on a time domain.

Step 203: the terminal equipment transmits PUSCH based on part or all of the first pre-configured authorized uplink resources; and the network equipment receives the PUSCH transmitted by the terminal equipment.

In an implementation manner of the present application, the first indication information is used to indicate at least one of: the number of time slots occupied by the first preconfigured authorized uplink resource, a start symbol in a first time slot occupied by the first preconfigured authorized uplink resource, an end symbol in a last time slot occupied by the first preconfigured authorized uplink resource, the resource length of the first preconfigured authorized uplink resource, and a determination mode of at least one preconfigured authorized uplink resource included in the first preconfigured authorized uplink resource; the starting position of at least one pre-configured authorized uplink resource included in the first pre-configured authorized uplink resource; and the ending position of at least one pre-configured authorized uplink resource included in the first pre-configured authorized uplink resource.

In an implementation manner of the present application, the determining, by the terminal device, a first preconfigured authorized uplink resource based on the first indication information includes:

the terminal equipment determines first information based on the first indication information, wherein the first information comprises at least one of the following information: the number of time slots occupied by the first preconfigured authorized uplink resource, the resource length of the first preconfigured authorized uplink resource, a start symbol of the first preset authorized uplink resource, an end symbol of the first preset authorized uplink resource, indication information used for indicating a determination manner of at least one preconfigured authorized uplink resource included in the first preconfigured authorized uplink resource, a start position of the at least one preconfigured authorized uplink resource included in the first preconfigured authorized uplink resource, and an end position of the at least one preconfigured authorized uplink resource included in the first preconfigured authorized uplink resource;

and the terminal equipment determines the first preconfigured authorized uplink resource based on the first information.

The first indication information may be a physical layer signaling, a higher layer signaling, or a Media Access Control (MAC) Control Element (CE).

The determining mode comprises a first determining mode and a second determining mode, the first determining mode is determined based on the time slot boundary, and the second determining mode is determined based on the second indication information.

For example, assume that the first indication information indicates that the start symbol of the first slot is S, the number of occupied slots is n, and the end symbol of the last slot is E. Optionally, the value range of S is from symbol 0 to symbol 13, the value range of E is from symbol 0 to symbol 13, the value range of N is from 1 to N, and N is the maximum number of configurable consecutive time slots, and then it is determined that the obtained first preconfigured authorized uplink resource is as shown in fig. 2B. Optionally, the value range of S is from symbol 1 to symbol 13, or the value range of E is from symbol 0 to symbol 12, that is, the starting symbol does not include the first symbol in the slot, or the ending symbol does not include the last symbol in the slot.

For another example, assuming that the first indication information indicates that the starting symbol of the first preconfigured authorized uplink resource is S and the resource length is L, the obtained first preconfigured authorized uplink resource is determined as shown in fig. 2C.

For another example, assuming that the first indication information indicates that the determination manner is the first determination manner, the starting position of the first preconfigured authorized uplink resource included in the first preconfigured authorized uplink resource is the symbol 7 of the time slot n, and the ending position of the last preconfigured authorized uplink resource included in the first preconfigured authorized uplink resource is the symbol 10 of the time slot n +3, the determined first preconfigured authorized uplink resource is as shown in fig. 2D.

In an implementation manner of the present application, the first preconfigured grant uplink resources include M second preconfigured grant uplink resources, where M is a positive integer.

It should be understood that if the value of M is 1, the first preconfigured authorized uplink resource and the second preconfigured authorized uplink resource may be considered to be the same resource.

Optionally, the M second preconfigured grant uplink resources are determined by at least one of:

determining the M second preconfigured authorized uplink resources based on the time slot boundary occupied by the first preconfigured authorized uplink resource;

determining the M second pre-configured authorized uplink resources based on second indication information.

The number of symbols included in the different second pre-configured authorized uplink resources may be the same or different, and is not limited herein. The second indication information is sent by the network device.

For example, assuming that there are 3 time slots occupied by the first preconfigured authorized uplink resource, and the first preconfigured authorized uplink resource starts from the symbol 7 of the first time slot and ends at the symbol 10 of the third time slot, it is determined that the obtained second preconfigured authorized uplink resource is as shown in fig. 2D.

In an implementation manner of the present application, the second indication information is used for indicating at least one of the following: the number of the second pre-configured authorized uplink resources included in the first pre-configured authorized uplink resource, the number of the second pre-configured authorized uplink resources included in a complete time slot, and the resource length of at least one second pre-configured authorized uplink resource included in a complete time slot.

Optionally, in case 1, a new parameter m is introduced, where m represents the number of PUSCHs included in the available P symbols in one slot.

The number of symbols included in each PUSCH except for the first PUSCH in the m PUSCHs is floor (P/m), the number of symbols included in the first PUSCH is P-floor (P/m) × (m-1), and the floor represents lower integer. For example, assuming that P is 14 and m is 4, the first PUSCH includes 14-floor (14/4) × (4-1) ═ 5 symbols, and each of the following 3 PUSCHs includes 3 symbols floor (14/4) ═ 3 symbols.

Or, the number of symbols included in each PUSCH except the last PUSCH in the m PUSCHs is floor (P/m), and the number of symbols included in the last PUSCH is P-floor (P/m) × (m-1). For example, assuming that P is 14 and m is 4, the last PUSCH includes 14-floor (14/4) × (4-1) ═ 5 symbols, and each of the first 3 PUSCHs includes 3 symbols floor (14/4) ═ 3 symbols.

Optionally, in a case that the time slot occupied by the first preconfigured authorized uplink resource includes a partial time slot and a full time slot, the PUSCH included in the full time slot may be determined according to the above method, that is, the number of symbols included in each PUSCH is floor (P/m) or P-floor (P/m) × (m-1).

Assuming that the number of symbols available for transmission of the PUSCH in the partial slot is X, the number of PUSCHs included in the partial slot is Y, and Y ═ floor (X/floor (P/m)). And the number of symbols included in each PUSCH except the first PUSCH in the Y PUSCHs is floor (P/m), and the number of symbols included in the first PUSCH is X-floor (P/m) × (Y-1). For example, assuming that P is 14, m is 4, and X is 8, for a full slot, the first PUSCH includes 5 symbols, and each of the following 3 PUSCHs includes 3 symbols; for the partial time slot, the number of the included PUSCHs is 2, wherein the number of the symbols included in the first PUSCH is 5, and the number of the symbols included in the next PUSCH is 3.

Or the number of symbols included in each PUSCH except the last PUSCH in the Y PUSCHs is floor (P/m), and the number of symbols included in the last PUSCH is X-floor (P/m) × (Y-1). For example, assume that P is 14, m is 4, and X is 8, the first PUSCH includes 5 symbols for a full slot, each PUSCH in the following 3 PUSCHs includes 3 symbols, and the number of PUSCHs included in a partial slot is 2, where the last PUSCH includes 5 symbols and the preceding PUSCH includes 3 symbols.

Optionally, a new parameter w is introduced, where w is used to indicate the number of symbols included in the PUSCH resources except for the first or last PUSCH among the available P symbols in one slot. For example, the number of symbols included in each PUSCH except for the first PUSCH (or the last PUSCH) is w, and the number of symbols included in the first PUSCH (or the last PUSCH) is P- ((floor (P/w) -1) × w). For example, assuming that there are 3 slots occupied by the first preconfigured authorized uplink resource, the first preconfigured authorized uplink resource starts from symbol 7 of the first slot and ends at symbol 10 of the third slot, P is 7 in the first slot, P is 14 in the second slot, P is 10 in the third slot, w is 4, and w represents the number of symbols included in PUSCHs other than the first PUSCH among the available P symbols in one slot, the obtained second preconfigured authorized uplink resource is determined as shown in fig. 2E.

Alternatively, in case 2, the slot boundary may be considered as the transmission boundary of the PUSCH, as specifically shown in fig. 2D.

It should be appreciated that for each PUSCH resource, the terminal device may perform CG-PUSCH transmission from that PUSCH resource after LBT is successful. As shown in fig. 2D, if the LBT succeeds before symbol 7 of slot n, the terminal device may start transmission from symbol 7 of slot n and may make up to 3 consecutive PUSCH transmissions until symbol 10 of slot n + 2. If the terminal device fails LBT before symbol 7 of slot n, the terminal device may perform LBT before symbol 0 of slot n +1 and transmit on slot n +1 after LBT success, and may perform 2 consecutive PUSCH transmissions at most until symbol 10 of slot n + 2. If the terminal device fails LBT before symbol 0 of slot n +1, the terminal device may perform LBT before symbol 0 of slot n +2 and transmit on slot n +2 after LBT succeeds until symbol 10 of slot n + 2. In this case, the starting position of each PUSCH resource may be considered as a starting position where the terminal device can initiate transmission.

However, it should be noted that, in the unlicensed spectrum, the downlink transmission of the network device and the uplink transmission of the terminal device share the same channel resource, and in a certain time slot configured as the CG resource, the network device may perform downlink transmission in the time slot, or the network device may also schedule other terminal devices to perform uplink transmission in the time slot, so that the network device should ensure that the terminal device configured with the CG resource in the time slot avoids causing collision to other transmissions in the time slot when performing PUSCH transmission. In general, the network device may start transmission from symbol 0 of one slot, or the network device may also schedule the terminal device to start transmission from symbol 0 of one slot. If the CG-PUSCH transmission is also performed in the above manner, when a terminal device starts to transmit the CG-PUSCH at symbol 0 of a certain slot, collision between the CG-PUSCH of the terminal device and downlink transmission of a network device or uplink transmission of other terminal devices may occur at the slot. As shown in fig. 2F, if the LBT succeeds before slot 1 and the network device and the terminal device start transmitting from symbol 0 of slot 1 at the same time, then transmission collisions between the network device and the terminal device may occur.

In order to solve the above problem, in an implementation manner of the present application, a terminal device performing PUSCH transmission based on part or all of the first preconfigured grant uplink resources includes:

and the terminal equipment performs PUSCH transmission on the Q second pre-configured authorized uplink resources based on PUSCH mapping modes corresponding to the Q second pre-configured authorized uplink resources, wherein the M second pre-configured authorized uplink resources comprise the Q second pre-configured authorized uplink resources, and Q is a positive integer less than or equal to M.

In an implementation manner of the present application, a third preconfigured authorized uplink resource corresponds to the first PUSCH mapping manner, and the M second preconfigured authorized uplink resources include the third preconfigured authorized uplink resource.

Optionally, the first PUSCH mapping manner satisfies at least one of the following conditions:

third indication information from the network equipment is used for determining the first PUSCH mapping mode;

the third preconfigured authorized uplink resource comprises a first symbol;

a first transmission starting position corresponding to the third preconfigured authorized uplink resource comprises a position in a first symbol in the third preconfigured authorized uplink resource;

the starting position of the third preconfigured authorized uplink resource is the first symbol;

the number of symbols included in the third preconfigured authorized uplink resource is greater than or equal to a first threshold.

Optionally, the first threshold value is 4 or other values.

Wherein the third indication information is used for indicating a PUSCH mapping manner of the M second preconfigured grant uplink resources. For example, when M is 3, the third indication information is used to indicate that the PUSCH mapping scheme for the first second preconfigured authorized uplink resource is the second PUSCH mapping scheme, the PUSCH mapping scheme for the second preconfigured authorized uplink resource is the first PUSCH mapping scheme, and the PUSCH mapping scheme for the third second preconfigured authorized uplink resource is the second PUSCH mapping scheme.

Or, the third indication information is second indication information, and information indicated by the second indication information is used for determining the first PUSCH mapping scheme. For example, the number of the second preconfigured authorized uplink resources is associated with the PUSCH mapping manners of the M second preconfigured authorized uplink resources in advance (for example, the PUSCH mapping manners of the M second preconfigured authorized uplink resources corresponding to the number of the second preconfigured authorized uplink resources being 3 are that the PUSCH mapping manner of the first second preconfigured authorized uplink resource is the second PUSCH mapping manner, the PUSCH mapping manner of the second preconfigured authorized uplink resource is the first PUSCH mapping manner, the PUSCH mapping manner of the third second preconfigured authorized uplink resource is the second PUSCH mapping manner, the PUSCH mapping manners of the M second preconfigured authorized uplink resources corresponding to the number of the second preconfigured authorized uplink resources being 2 are that the PUSCH mapping manner of the first second preconfigured authorized uplink resource is the second PUSCH mapping manner, the PUSCH mapping manner of the second preconfigured authorized uplink resource is the first PUSCH mapping manner, and so on), and determining a second PUSCH mapping mode corresponding to the third preconfigured authorized uplink resource according to the number of the second preconfigured authorized uplink resources indicated by the second indication information.

Or the third indication information is second indication information, where the information indicated by the second indication information is used to determine the positions of the M second preconfigured authorized uplink resources, and a PUSCH mapping manner corresponding to at least one of the M second preconfigured authorized uplink resources is determined according to the position of the at least one of the M second preconfigured authorized uplink resources. For example, the position of the second preconfigured authorized uplink resource is associated with the PUSCH mapping modes of M second preconfigured authorized uplink resources in advance, for example, the starting symbol of the second preconfigured authorized uplink resource includes the first symbol in a certain slot, and the PUSCH mapping mode of the second preconfigured authorized uplink resource is the first PUSCH mapping mode; or, if the starting symbol of the second preconfigured authorized uplink resource does not include the first symbol in a certain slot, the PUSCH mapping mode of the second preconfigured authorized uplink resource is the second PUSCH mapping mode.

Or, the second preconfigured authorized uplink resource includes a complete slot, and then the PUSCH mapping manner of the second preconfigured authorized uplink resource is the first PUSCH mapping manner.

Optionally, the terminal device performs PUSCH transmission on the Q second preconfigured grant uplink resources, including:

on the third preconfigured authorized uplink resource, the terminal device transmits a first PUSCH, where the first PUSCH includes: first preconfigured grant Uplink Control Information (CG-UCI).

It should be noted that the transmission position of the PUSCH may refer to a position where the PUSCH starts to be transmitted, and the transmission position of the PUSCH may include a CP transmitted or a punctured partial symbol. The starting position of the PUSCH may refer to a starting position of an effective symbol for pre-configuring the authorized uplink resource, and the starting position of the PUSCH may include a Demodulation Reference Signal (DMRS) symbol. For example, the effective symbols of the pre-configured authorized uplink resource are from symbol 7 to symbol 13, the position where the PUSCH starts to transmit is symbol 6, the transmission position of the PUSCH is symbol 6, and the starting position of the PUSCH is symbol 7. If after the transmission is started, on the middle preconfigured authorized uplink resource, the transmission starting position corresponding to the middle preconfigured authorized uplink resource and the PUSCH starting position transmitted on the middle preconfigured authorization may be the same position. Assuming that the first preconfigured authorized uplink resources comprise 3 second preconfigured authorized uplink resources (such as PUSCH0, PUSCH1 and PUSCH2), if transmission of PUSCH is started on PUSCH0, the corresponding transmission starting position on PUSCH1 or PUSCH2 and the PUSCH starting position transmitted on PUSCH1 or PUSCH2 may be the same position.

The second transmission starting position corresponding to PUSCH0 is located in symbol 6, and the first transmission starting positions corresponding to PUSCH1 and PUSCH2 are both located in symbol 0.

For another example, taking the second preconfigured authorized uplink resource shown in fig. 2E as an example, assuming that the first symbol is symbol 0, the PUSCH mapping scheme corresponding to PUSCH0 shown in fig. 2E is the second PUSCH mapping scheme, the PUSCH mapping scheme corresponding to PUSCH1 is the first PUSCH mapping scheme, the PUSCH mapping scheme corresponding to PUSCH2 is the second PUSCH mapping scheme, the PUSCH mapping scheme corresponding to PUSCH3 is the second PUSCH mapping scheme, the PUSCH mapping scheme corresponding to PUSCH4 is the first PUSCH mapping scheme, and the PUSCH mapping scheme corresponding to PUSCH5 is the second PUSCH mapping scheme. The position of the second reference signal corresponding to PUSCH0 is symbol 7, the position of the second reference signal corresponding to PUSCH2 is symbol 6, the position of the second reference signal corresponding to PUSCH3 is symbol 10, and the position of the second reference signal corresponding to PUSCH5 is symbol 7, and assuming that the position of the first reference signal is configured as symbol 2 in the first PUSCH mapping manner, the positions of the first reference signals corresponding to PUSCH1 and PUSCH4 are both symbol 2. The second transmission starting position corresponding to PUSCH0 is located in symbol 6, the first transmission starting positions corresponding to PUSCH1 and PUSCH4 are both located in symbol 0, the second transmission starting position corresponding to PUSCH2 is located in symbol 5, the second transmission starting position corresponding to PUSCH3 is located in symbol 9, and the second transmission starting position corresponding to PUSCH5 is located in symbol 6.

If the timing offset corresponding to PUSCH0 is timing offset 0, if the LBT succeeds before timing offset 0 in symbol 6 of slot n, the terminal device may start transmission from timing offset 0 in symbol 6 of slot n, and the specific transmission diagram is shown in fig. 2J.

If the timing offset corresponding to the PUSCH1 is timing offset 1, if the terminal device fails to transmit on the PUSCH0, LBT succeeds before timing offset 1 in symbol 0 of slot n +1, and the terminal device may start to transmit from timing offset 1 in symbol 0 of slot n +1, where a specific transmission diagram is shown in fig. 2K.

If the timing offset corresponding to the PUSCH4 is timing offset 2, if the terminal device fails to transmit on PUSCH0, fails to transmit on PUSCH1, fails to transmit on PUSCH2, fails to transmit on PUSCH3, and LBT succeeds before timing offset 2 in symbol 0 of slot n +2, the terminal device may start transmission from timing offset 2 in symbol 0 of slot n +2, and the specific transmission diagram is shown in fig. 2L.
