Description

Transmission resource indication method and device

Technical Field

The present application relates to the field of mobile communications technologies, and in particular, to a method and an apparatus for indicating transmission resources.

Background

In the current wireless communication technology, two modes of dynamic scheduling and semi-static scheduling can be adopted when uplink and/or downlink data scheduling is carried out. In both of these two approaches, the time domain location of the scheduled transmission resource is determined according to the time domain location information of the control channel. The method specifically comprises the following steps: and the time domain position of the transmission resource scheduled by the control channel is determined jointly according to the time domain position of the control channel and the time domain information indicated by the control information carried by the control channel. For example, the network device schedules uplink and/or downlink data through Downlink Control Information (DCI) carried by a Physical Downlink Control Channel (PDCCH), and a time domain position of a transmission resource for transmitting the uplink and/or downlink data is jointly determined according to the time domain position of the PDCCH and time domain information indicated in the DCI.

However, since the time domain information that can be indicated in the DCI agreed in the current air interface protocol is limited, the above method for determining the time domain position of the uplink and/or downlink data by using the time domain position of the control channel and the time domain information indicated in the control information is not flexible enough.

Disclosure of Invention

The application provides a transmission resource indication method and device, which are used for indicating the time domain position of uplink and/or downlink data more flexibly.

In a first aspect, the present application provides a transmission resource indication method, which may be implemented by a first communication device. According to the method, a first communication device may determine first information indicating a first reference point so that the first reference point is used to determine a time domain location of transmission resources used for data transmission between the first communication device and a second communication device to which the first communication device may send the first information.

By adopting the method, the first communication device can indicate the first reference point through the first information, the second communication device can determine the time domain position of the transmission resource according to the first reference point, and then uplink and/or downlink data transmission between the first communication device and the second communication device can be carried out according to the transmission resource. Based on the method, flexible indication of the time domain position of the transmission resource can be realized.

In one possible design, the first information may include a position of the first reference point in a first period, where the first period includes a semi-persistent scheduling period, a period of the first type of traffic, or a period of the first reference point. The first type of service may include periodic uplink and/or downlink data transmission. By adopting the design, the first information can indicate the time domain position of the first reference point in a mode of carrying the position of the first reference point in the first period, so that the flexible indication of the first reference point is realized.

Optionally, the offset is a preconfigured value, or the offset is included in the first information. Optionally, the first information may include information of a second period, where the second period includes a semi-persistent scheduling period, a period of the first type of service, or a period of the second reference point. With the above design, the indication of the first reference point can be realized by indicating the second reference point, and thus the first reference point can be indicated more flexibly.

In one possible design, the first information may include information of the first search space and/or information of the first set of control resources.

With this design, the first information may be combined with the second information to indicate a time-domain position of the first reference point to enable flexible indication of the first reference point.

In one possible design, the first communications apparatus may scramble the second information based on the first RNTI and transmit the scrambled second information to the second communications apparatus. Wherein the first RNTI is used to indicate that the time domain position of the transmission resource is determined according to the first reference point. By adopting the design, the first communication device can indicate the second communication device to determine the time domain position of the transmission resource according to the first reference point through the first RNTI, so that the determination mode of the transmission resource is consistent between the first communication device and the second communication device, and the indication success rate and the indication efficiency of the transmission resource are improved.

In one possible design, the first communication device may send third information to the second communication device, the third information indicating that the time domain location of the transmission resource is determined according to the first reference point. By adopting the design, the first communication device can instruct the second communication device to determine the time domain position of the transmission resource according to the first reference point through the third information, so that the determination mode of the transmission resource is agreed between the first communication device and the second communication device, and the indication success rate and the indication efficiency of the transmission resource are improved.

The implicit indication means that the first information may carry information related to the first reference point, and the information does not directly indicate information of the first reference point, but the terminal device 101 may determine the first reference point according to the information, for example, there is a correspondence between the information and the first reference point, so that the terminal device 101 may determine the first reference point according to the correspondence, or the information may be used to derive the first reference point, so that the terminal device 101 may determine the first reference point according to the information.

The presetting or pre-configuration is to pre-configure information and/or data in the factory or debugging process of the device, and directly adopt the information and/or data when relevant operations are executed. The information and/or data described herein includes, but is not limited to, configuration information or configuration parameters required for configuring the network device 102 and the terminal device 101, and information or parameters required for performing the operations related to the present application by the network device 102 and the terminal device 101, respectively.

For example, as shown in fig. 7, if the length of the first period is 10 milliseconds (ms), the starting position of the first period is 0 th time unit, the starting position of the first period is shown by an arrow in the figure, the position of the first reference point is shown by a circle in the figure, and the first information may include an offset X between the first reference point and the starting position in the first period, for example, X is 5 time units. The terminal device 102 may determine that the first reference point is located at the 5 th time unit according to the starting position of the first cycle and the offset X.

It should be understood that the above X may be a value configured and indicated to the terminal device 101 by the network device 102, or may be a value defined or pre-configured by a protocol.

Alternatively, in another possible implementation, the information of the position of the first reference point in the first period may include information of a time unit in which the first reference point is located in the first period. Still taking the first reference point shown in fig. 7 as an example, the information of the position of the first reference point in the first period may include a number of a time unit in which the first reference point is located, for example, the number is 5.

The time unit referred to above may include a slot (slot), a symbol (symbol), an absolute time length, or other time units. The network device 102 may configure and indicate the time unit to the terminal device 101, or the time unit may be set in a manner defined or preconfigured by the protocol.

The absolute time length here refers to N milliseconds or M microseconds (μ s), etc., and M, N are integers and refer to a fixed length of time, e.g., the absolute time length is 20 μ s or 50 μ s.

The other time unit may be a time length determined according to one or more of subcarrier spacing (SCS) of PDCCH, SCS of PDSCH, or SCS of PUSCH between network device 102 and terminal device 101, for example, the length of the other time unit may be a length of m0 slots or symbols at the smallest, largest, or next largest SCS in the above SCS, and m0 is an integer. The network device 102 may instruct the terminal device 101 according to which SCS to determine the length of the other time unit, or may set in advance by which SCS to determine the length of the other time unit. For example, when the SCS of the PDCCH and the SCS of the PDSCH are 15 kilohertz (KHz) and 30KHz, respectively, if the length of the other unit is 1 symbol length of the SCS of the PDCCH, the length of the other unit is 1/14 ms. Alternatively, the length of the other time units may be a length of time associated with the first period, e.g., one quarter of the first period. In one possible implementation, the first cycle referred to above may comprise a semi-persistent scheduling (semi-persistent scheduling) cycle. In an implementation, the period of the semi-persistent scheduling referred to above may be configured by the network device 102 to the terminal device 101. For example, the network device 102 may indicate the length of the semi-persistent scheduling period and/or the starting position of the semi-persistent scheduling period to the terminal device 101 through configuration information, such as one of a Radio Resource Control (RRC) message, a Medium Access Control (MAC) layer Control Element (CE), or DCI.

In another possible implementation, the first period may include a period of a first type of service, and the first type of service may include periodic uplink and/or downlink data transmission. The first type of service referred to herein may include a service in which the network device 102 configures a CT to the terminal device 101, and the terminal device 101 performs periodic uplink and/or downlink data transmission to the network device 102 according to the CT. The above first information may include a position of the first reference point within the CT, and the terminal device 101 may determine a time domain position of the first reference point according to the position of the first reference point within the CT. Wherein, the network device 102 may configure the length and the starting position of the CT to the terminal device 101 through an RRC message.

In another possible implementation, the first period may include a first reference point period. For example, the plurality of first reference points occur with a period of 10ms, and the first information may include the period. Alternatively, the length of the period of the first reference point may be semi-static schedulingPeriod (or CT period) 2^gOne in one or 2^hAnd (b) multiplying, wherein g and h are positive integers.

The network device 102 may indicate to the terminal device 101 a period having the above first period as a first reference point. Alternatively, the network device 102 and/or the terminal device 101 may be caused to use the above first period as the period of the first reference point in a manner defined or preconfigured by the protocol.

In addition, if the number of the first reference points is one, if the first information includes information of time domain positions of the first reference points in the semi-persistent scheduling period, the terminal device 101 may use the time domain position indicated by the first information in the semi-persistent scheduling period where the first information is located as the time domain position of the first reference point; or, the terminal device 101 may use the time domain position in an nth semi-persistent scheduling period before or after the semi-persistent scheduling period, where the time domain position indicated by the first information is used as the time domain position of the first reference point, a value of n may be indicated by the network device 102 through the first information or other signaling, or may be defined by a protocol or determined in a preconfigured manner, and n is a positive integer.

If the number of the first reference points is one, if the first information includes information of time domain positions of the first reference points in the period of the first type service, the terminal device 101 may use the time domain position indicated by the first information in the period of the first type service where the first information is located as the time domain position of the first reference point; or, the terminal device 101 may use the time domain position indicated by the first information as the time domain position of the first reference point in the mth period of the first service before or after the period of the first service, where the value of m may be indicated by the network device 102 through the first information or other signaling, or may be defined by a protocol or determined in a preconfigured manner, and m is a positive integer. In the second mode, the first information includes information of a position of the first reference point in the first period and first period information. The network device 102 may indicate information of a position of the first reference point in the first period and the first period information to the terminal device 101, so that the terminal device 101 may determine a time-domain position of the first reference point from the position information and the first period information. The determined temporal position of the first reference point may comprise the temporal position of the first reference point within each period. The determined temporal position of the first reference point may comprise temporal positions of a plurality of reference points.

The description will be given taking a period in which the first period is the first reference point as an example. As shown in fig. 8, if the time domain positions of the plurality of periodically occurring first reference points are shown as circles in the figure, the first information may include information of the position of any one first reference point (e.g., the first reference point) and information of the period of the first reference point. The position information of the first reference point may be represented by a number of any one of a system frame, a time slot, a symbol, or a subframe where the first reference point is located, or may be represented by absolute time, or a position where the first reference point is located in the first period.

When the position of the first reference point in the first period represents the time domain position of the first reference point, the first information may include an offset between the first reference point and the start position of the first period and/or a time unit in which the first reference point is located in the first period, and a specific method thereof may refer to the description in method one.

It should be appreciated that for the case where the network device 102 has configured a semi-persistent scheduling period before transmitting the first information, reference may be made to the above scheme of the period of the first reference point. Such as replacing the length of the period of the first reference point in the first period with the length of the semi-persistent scheduling period. Or, the length of the period of the first reference point may be the same as the length of the semi-persistent scheduling period that has been configured by the network device 102 before the first information is transmitted. For the case where the network device 102 has configured the CT period before sending the first information, reference may be made to the above-described scheme of the period of the first reference point. Such as replacing the length of the period of the first reference point in the first period with the length of the CT period. Or, the length of the period of the first reference point may be the same as the length of the CT period that the network device 102 has configured before sending the first information.

In a third mode, the first information includes information of a time domain position of the second reference point, and an offset is provided between the second reference point and the first reference point in a time domain. The time domain position of the second reference point may be represented by a number of any one of a system frame, a time slot, a symbol, or a subframe where the second reference point is located, or may be represented by absolute time, or a time domain position of the second reference point in the second period. Here, the second period may be a period of semi-persistent scheduling, a period of a first type of service, or a period of a second reference point, and taking the semi-persistent scheduling period as an example, the first information may include a time domain position of the second reference point in the semi-persistent scheduling period. In addition, the first information may further include information of the second period, such as a length of the second period and/or a time domain position of the second period. For example, the length of the period of the second reference point may be the same as the length of the period of the first reference point.

When the time domain position of the second reference point in the second period represents the time domain position of the second reference point, the first information may include an offset between the second reference point and the start position of the second period and/or a time unit in which the second reference point is located in the second period.

For example, the offset between the second reference point and the first reference point in the time domain may be a value configured by the network device 102, and specifically, the first information may include an offset between a time domain position of the second reference point and a time domain position of the first reference point. Alternatively, the offset may be set by protocol definition or preconfigured way. Or, the offset is determined according to the capability parameter reported by the terminal device 101, and after the terminal device 101 reports the capability, both the terminal device 101 and the network device 102 know the value. Alternatively, the offset may be associated with a specific service type, for example, configuration parameters obtained by the terminal device 101 from a predefined location, where the predefined location includes a memory, a disk, a core network, a configuration server, or other entity that can communicate with the network device. It should be understood that the above offset may be expressed in time units, for example, the offset is y time units, y is an integer, and the method of determining the time units is referred to above.

As shown in fig. 9, if the time-domain position of the second reference point (as indicated by the arrow in the figure) is represented as position a1, and the offset between the second reference point and the first reference point in the time domain is 5 time units, the time-domain position B1 of the first reference point (as indicated by the circle in the figure) can be represented as B1, which is a1+5 time units.

In a fourth mode, the network device 102 may send second information to the terminal device 101, where the second information indicates the transmission resource related to S101. Specifically, the second information may be control information used for scheduling uplink and/or downlink data, such as DCI, where the DCI is used to indicate transmission resources for uplink and/or downlink data transmission between the network device 102 and the terminal device 101, and the first information may include an offset between a time domain position of the first reference point and a time domain position of the second information. In this embodiment, the first information and the second information may be the same control information, such as DCI.

It should be understood that the time domain position of the second information here may include the number of the time slot, symbol or subframe occupied by the second information, such as the number of the first time slot/last time slot occupied by the DCI. The temporal location may also be represented by a time unit, e.g. the temporal location of the second information may be represented by the time unit in which it was located in the first period. Specifically, the second information may be control information under dynamic scheduling, or may be control information under semi-static scheduling.

For example, the offset between the time domain position of the first reference point and the time domain position of the second information may be a value configured by the network device 102, or the offset may be determined by a protocol definition or a preconfigured way. Specifically, the first information may include an offset between a time-domain position of the second information and a time-domain position of the first reference point. It should be understood that the above offset may be expressed in time units, for example, the offset is y time units, y is an integer, and the method of determining the time units is referred to above.

Taking the semi-persistent scheduling as an example, as shown in fig. 10, if the time domain position of the second information (as indicated by an arrow in the figure) sent by the network device 102 to the terminal device 101 is represented as position a2, and the offset between the time domain position of the second information and the first reference point in the time domain is 5 time units, the time domain position B2 of the first reference point (as indicated by a circle in the figure) adjacent to the second information may be represented as B2, which is a2+5 time units. The temporal position of the first reference point, which occurs subsequently periodically, may be determined from position B2 and the period of the first reference point.

And a fifth mode, setting multiple sets of Search Space (SS) and/or control resource set (CORESET) configurations in a protocol-defined or pre-configured mode, where in each set of configurations, the search space and/or the control resource set correspond to a time domain position of the first reference point, and the network device 102 may determine, through the search space or the control resource set, a resource for transmitting the second information, and transmit the second information through the resource, so that the terminal device may determine the first reference point according to the resource for transmitting the second information and the configuration.

For example, a table of time domain location correspondences of search space and/or control resource sets with first reference points may be set as shown in table one, it can be seen that the search space S1 corresponds to the group 1 first reference point, the control resource set C1 corresponds to the group 2 first reference point, and in addition, the search space S2 and the control resource set C2 correspond two by two with the group 3 first reference point.

Search space	Controlling resource collections	First reference point
			Search space S1	/	Group 1 first reference point
/	Control resource set C1	Group 2 first reference point
			Search space S2	Control resource set C2	Group 3 first reference point
……	……	……

Watch 1

In an implementation, if the network device 102 indicates the 1 st group of first reference points to the terminal device 101, the network device 102 may determine a resource for transmitting the second information according to the search space S1 and transmit the second information through the resource, and after receiving the second information, the terminal device 101 may determine the first reference point as the 1 st group of first reference points according to the table one if the resource for transmitting the second information is determined according to the search space S1, wherein a time domain position of the 1 st group of first reference points may be indicated by the network device 102 through the second information or through signaling separately, or defined by a protocol, or determined by a preconfigured manner. If the network device 102 indicates the 2 nd group first reference point to the terminal device 101, the network device 102 may determine the resource for transmitting the second information according to the control resource set C1, and after the terminal device 101 may receive the second information, if the resource for transmitting the second information is determined according to the control resource set C1, the first reference point may be determined as the 2 nd group first reference point according to table one, where a time domain position of the 2 nd group first reference point may be indicated by the network device 102 through the second information or through signaling, or defined by a protocol, or determined by a preconfigured manner. In addition, if the network device 102 indicates the 3 rd group first reference point to the terminal device 101, the network device 102 may determine a resource for transmitting the second information according to the search space S2 and transmit the second information through the resource, and after receiving the second information, the terminal device 101 may determine the first reference point as the 3 rd group first reference point according to the first table if it is determined that the resource for transmitting the second information is determined according to the search space S2; alternatively, the network device 102 may determine the resource for transmitting the second information according to the control resource set C2, and after receiving the second information, the terminal device 101 may determine the first reference point as the group 3 first reference point according to table one if it is determined that the resource for transmitting the second information is determined according to the control resource set C2. Wherein the time domain position of the group 3 first reference point may be indicated by the network device 102 through the second information or otherwise through signaling, or defined by a protocol, or determined in a preconfigured manner.

When the number of the first reference points is one, the network device 102 may carry information of the time domain position of the first reference point in the first information, for example, the first information may include a number of any one of a system frame, a time slot, a symbol, or a subframe where the first reference point is located. Alternatively, the network device 102 indicates the plurality of first reference points through other information (e.g. RRC message), or determines the plurality of first reference points through a protocol definition or a pre-configuration manner, and thereafter, the network device 102 specifically indicates one of the first reference points through the first information to be used for determining the time domain position of the transmission resource, e.g. there is a corresponding relationship between the first information and the one first reference point. It should be understood that if the number of the first reference points is one, the network device 102 may indicate a plurality of first reference points through a plurality of different first information.

Optionally, if the number of the first reference points is multiple, the network device 102 may carry indication information in the second information sent to the terminal device 101, where the indication information is used to indicate that the terminal device 101 determines, according to an xth first reference point whose time domain position is before or after the time domain position of the second information, the time domain position of the transmission resource of the uplink and/or downlink data scheduled by the second information, where x is a non-zero integer. For example, the second information may represent x by 1 or more bits, and when the sign of x is positive (or negative), it represents that the time domain position of the transmission resource is determined according to the xth first reference point of the time domain position after the time domain position of the second information, and when the sign of x is negative (or positive), it represents that the time domain position of the transmission resource is determined according to the xth first reference point of the time domain position before the time domain position of the second information.

As shown in fig. 11, if the network device 102 indicates a plurality of first reference points (as indicated by circles in the figure) through the first information, and the time domain position of the second information sent by the network device 102 is indicated by an arrow in the figure, when the second information carries information indicating that x is 1, it indicates that the time domain position of the transmission resource is determined according to the 1 st first reference point after the time domain position of the second information. And when the second information carries information representing that x is-1, the information represents that the time domain position of the transmission resource is determined according to the 1 st first reference point before the time domain position of the second information.

In addition, the indication information may be used to indicate that the terminal device 101 determines the time domain position of the transmission resource according to a first reference point whose time domain position is before or after the time domain position of the second information, and according to the indication information, the terminal device 101 may determine the time domain position of the transmission resource according to an xth first reference point before or after the time domain position of the second information, where a value of x is defined by a protocol or determined in a preconfigured manner. For example, when the bit is configured to be 0 (or 1), it indicates that the terminal apparatus 101 determines the time domain position of the transmission resource according to the first reference point before the second information, and when the bit is configured to be 1 (or 0), it indicates that the terminal apparatus 101 determines the time domain position of the transmission resource according to the first reference point after the second information.

When the number of the first reference points is multiple and the terminal device 101 receives the second information sent by the network device 102, the manner for the terminal device 101 to determine the time domain position of the transmission resource of the uplink and/or downlink data scheduled by the second information may include the following several ways:

in the first mode, if the offset between the time domain position of a certain first reference point and the time domain position of the second information belongs to a specific range, the time domain position of the transmission resource is determined according to the first reference point. The specific range may be a preset time window, the length of which may be configured by the network device 102, or defined by a protocol or determined by a preconfigured way, or the length of which may be the length of the first period. It is to be understood that the temporal position of the first reference point may be located before or after the temporal position of the second information.

As shown in fig. 12, when the time domain position of a certain first reference point belongs to a specific range centered on the time domain position of the second information, the time domain position of the transmission resource of the uplink and/or downlink data scheduled by the second information may be determined according to the first reference point. In addition, the time domain position of the second information may not be located at the center position of the specific range, for example, the specific range may include a time domain interval offset a before the time domain position of the second information and a time domain interval offset b after the time domain position of the second information. Alternatively, the length of offset a may be equal to or not equal to the length of offset b.

As also shown in fig. 13, when the time domain position of the second information belongs to a specific range centered on the time domain position of a certain first reference point, the time domain position of the transmission resource of the uplink and/or downlink data scheduled by the second information may be determined according to the first reference point. In addition, the time domain position of the first reference point may not be located at the center position of the specific range, for example, the specific range may include a time domain interval offset c before the time domain position of the first reference point and a time domain interval offset d after the time domain position of the first reference point. Wherein, the length of the offset c may be equal to or not equal to the length of the offset d.

And secondly, determining the time domain position of the transmission resource according to the first reference point closest to the time domain position of the second information, wherein the offset between the time domain position of one first reference point and the time domain position of the second information is smaller than the offset between the time domain position of any other first reference point and the time domain position of the second information, namely the first reference point is the first reference point closest to the time domain position of the second information. It is to be understood that the temporal position of the first reference point closest to the temporal position of the second information may be located before or after the temporal position of the second information.

As shown in fig. 14, if the time domain position of the second information (as indicated by an arrow position in the figure) is the nth slot, and there is a first reference point (as indicated by a solid circle position in the figure) nearest to the nth + K slots, the terminal device 101 may determine the transmission resource of the uplink and/or downlink data scheduled by the second information according to the first reference point.

Determining the time domain position of the transmission resource of the uplink and/or downlink data scheduled by the second information according to the first reference point if the time domain position of the second information is between the time domain position of any one second reference point and the time domain position of the first reference point determined according to the second reference point; and if the time domain position of the second information is located between the time domain position of any one first reference point and the time domain position of a first second reference point after the time domain position of the first reference point, determining the time domain position of the transmission resource of the uplink and/or downlink data scheduled by the second information according to the first reference point after the time domain position of the first reference point.

As shown in fig. 15(a), if the time domain position of the second information (as shown by the arrow position in fig. 15 (a)) is located between the second reference point q1 and the first reference point q2 (as shown by the solid circle position in fig. 15 (a)), the terminal device 101 may determine the transmission resource of the uplink and/or downlink data scheduled by the second information according to the first reference point q 2.

As shown in fig. 15(b), if the time domain position of the second information (as shown by the arrow position in fig. 15 (b)) is located between the first reference point q3 (as shown by the circle position in fig. 15 (b)) and the second reference point q4, the terminal device 101 may determine the transmission resource of the uplink and/or downlink data scheduled by the second information according to the first reference point q5 (as shown by the solid circle position in fig. 15 (b)). Illustratively, the first reference point q5 is determined according to the second reference point q4, and the specific method thereof can refer to the description of the embodiment section of the present application.

Illustratively, the network device 102 sends the terminal device 101 the third information, which can be used to instruct the terminal device 101 to determine the time domain position of the transmission resource according to the method provided in the embodiment of the present application, that is, to determine the time domain position of the transmission resource according to the first reference point by the terminal device 101. Specifically, the third information may be carried in the second information, for example, a bit in the second information is configured as 1 (or 0), and the bit may be used to indicate that the terminal device 101 determines the time domain position of the transmission resource according to the first reference point.

In addition, network device 102 may scramble second information using a Radio Network Temporary Identifier (RNTI), and send the scrambled second information to terminal device 101, and terminal device 101 receives the scrambled second information, and determines the time domain position of the transmission resource according to the first reference point after determining the second information according to the RNTI, otherwise, terminal device 101 still determines the time domain position of the transmission resource according to the second information. The RNTI may be preset.

Specifically, the terminal apparatus 101 may be configured with an RNTI corresponding to a first type of service (e.g., a CT type service) to which the present application relates by the network apparatus 102, where the RNTI may be used for the network apparatus 102 to scramble a part of second information, and the second information is used for scheduling uplink and/or downlink data belonging to the first type of service. After descrambling the second information according to the RNTI, the terminal device 101 may determine the transmission resources of the uplink and/or downlink data according to the first reference point, so that the terminal device 101 may transmit the uplink and/or downlink data of the first type of service through the transmission resources determined by the first reference point. It should be understood that the RNTI corresponding to the above first type service may also be defined by a protocol or set in a preconfigured manner.

In addition, the network device 102 configures a generation manner of the RNTI for the terminal device 101, and when the time domain position of the transmission resource needs to be determined according to the first reference point, the network device 102 may generate the RNTI by using the method and perform scrambling on the second information, so as to instruct the terminal device 101 to determine the time domain position of the transmission resource according to the first reference point. It should be understood that the above generation manner of the RNTI may also be set by protocol definition or by a pre-configured manner.

Illustratively, the network device 102 configures time-frequency resources of a PDCCH corresponding to the first type of service in advance, and then generates the RNTI according to the time-frequency resources of the PDCCH, for example, the RNTI is determined according to part or all information in information such as an index of a time-domain position of the PDCCH (e.g., a number of a first/last slot/symbol occupied by the PDCCH), a frequency-domain position of the PDCCH, a frequency-domain resource index of the PDCCH, a resource size of the PDCCH, or an aggregation level of the PDCCH. The aggregation level is a combination mode of PDCCH time frequency resources, and different aggregation levels correspond to different resource sizes. For example, the following formula may be employed to determine the RNTI:

RNTI ═ R + j × S + k × T; (formula one)

Wherein, R represents the index of the first symbol of the PDCCH in the system frame, S represents the index of the frequency domain position of the PDCCH, T represents the occupied resource size of the PDCCH, and j and k are positive integers.

Optionally, the network device 102 may carry the third information in an RRC or MAC CE message, and send the third information to the terminal device 101.

It should be understood that the above-mentioned determining, by the terminal device 101, the time domain position of the transmission resource according to the first reference point may refer to determining, by the terminal device 101, the time domain position of the transmission resource for transmitting the initial transmission data according to the first reference point. When the terminal device 101 performs transmission of retransmission data, the time domain position of the transmission resource may be determined in the same manner as the initial transmission data. In addition, for the transmission of the initial transmission data, the terminal device 101 may also determine the time domain position of the transmission resource according to the first reference point, and it is not necessary to determine whether to determine the time domain position of the transmission resource according to the first reference point according to the second information or the third information.

It should also be understood that the above-mentioned determining, by the terminal device 101, the time domain position of the transmission resource according to the first reference point may refer to determining, by the terminal device 101, the time domain position of the transmission resource for transmitting data scheduled by the network device 102 in the semi-persistent scheduling manner according to the first reference point. For data scheduled by the network device 102 in the semi-persistent scheduling manner, the terminal device 101 may also determine the time domain position of the transmission resource according to the first reference point, and it is not necessary to determine whether to determine the time domain position of the transmission resource according to the first reference point according to the second information or the third information.

In implementation, for a scheme that the network device 102 configures, or determines the first period in a protocol definition or preset manner, if the terminal device 101 determines that the time domain position of the second information received in a cycle period is located before the time domain position of the first reference point in the cycle period, the terminal device 101 may determine the time domain position of the transmission resource according to the first reference point.

As shown in fig. 16(a), if the time domain position of the second information received by the terminal device 101 is shown as the arrow position in fig. 16(a), it can be seen that, in the first period in which the second information is located, the time domain position of the second information is located before the time domain position of the first reference point (shown as the solid circle position in fig. 16 (a)), the terminal device 101 may determine the transmission resource of the uplink and/or downlink data scheduled by the second information according to the first reference point.

As shown in fig. 16(b), if the time domain position of the second information received by the terminal device 101 is shown as the arrow position in fig. 16(b), it can be seen that, in the first period in which the second information is located, the time domain position of the second information is located behind the time domain position of the first reference point (shown as the solid circle position in fig. 16 (b)), the terminal device 101 may not determine the transmission resource of the uplink and/or downlink data scheduled by the second information according to the first reference point. At this time, the terminal apparatus 101 may determine the time domain position of the transmission resource from the time domain position of the second information.
