Description

The present invention claims PCT priority of patent application PCT/CN2017/110533, filed with the PRC Patent Office on November 10, 2017, titled "Method and Apparatus for Data Communication", which is incorporated herein by reference in its entirety.

The field to which the invention relates

Embodiments of the present invention relate to the field of communications and, more specifically, to a method and apparatus for data transmission.

State of the art

Under the 5G New Radio (NR) system, an Ultra-Reliable Low Latency Communication service (URLC) is introduced, which is characterized in that ultra-high reliability (e.g., 99.999%) and extremely low data transmission can be carried out. latency (for example, 1 ms). To achieve the above goal, the concept of scheduling without allocation of resources is proposed. The non-provisioning scheduling mode provides a semi-static configuration mode (eg, Type 1 mode) or a semi-static configuration plus dynamic initiation mode (eg, Type 2 mode) as the resource configuration mode. The end device can transmit data to resources with a semi-static configuration (Type 1) or with a semi-static configuration plus dynamic initiation (Type 2) according to the needs of the service, thus eliminating the process of initiating a resource request (SR) and buffer status reports (Buffer Status Report , BSR), as well as increasing the effective transmission time of the end device.

However, in unallocated scheduling mode, resources are consumed dynamically, which increases the difficulty of blindly detecting a network device. Sometimes there may be a situation where services cannot be transmitted in time due to limited dynamic resource allocation (for example, when limited in the area of the initial data sending), thus degrading the user experience. Thus, there is a need for a technical solution to solve the problem described above.

Within an embodiment of the present invention, the non-provisioning configured mode may include two types, namely Type 1 and Type 2. Here, Type 1 is for configuring a non-provisioning scheduled resource (which may also be referred to as a non-dynamic resource) using a protocol-transmitted a radio resource control (RRC) signal, wherein the unscheduled resource may include a time-frequency resource, pilot information, modulation coding mode, power management parameters, and other information.

It should be noted that the configuration information within an embodiment of the present invention is configuration information specific to a non-dynamic resource (i.e., a scheduled non-provisioning resource), or in other words, the configuration information is used to configure the non-dynamic resource. A non-dynamic resource is a resource for transmission with non-dynamic scheduling, and a non-dynamic scheduling is a scheduling mode other than dynamic scheduling (for example, scheduling by signaling at the physical layer), such as a transmission mode with a semi-static configuration (for example, Type 1 transmission mode) or a transfer mode with semi-static configuration plus dynamic initiation (eg, Type 2 transfer mode).

В соответствии с концепциями в рамках вариантов осуществления настоящего изобретения, полученные соответствующие технические решения, указывающие на начальное положение или конечное положение для передачи данных по восходящему каналу на частотном ресурсе или кодовом ресурсе, включаются в область вариантов осуществления настоящего изобретения, для которых испрашивается защита.It should be noted that, within an embodiment of the present invention, the aforementioned non-dynamic resource may be a time resource, a time-frequency resource, or a code resource, and so on, for non-dynamic scheduling transmission. Similarly, the start position for transmission of an uplink data unit may mean a start position (ie start time position) of a time resource in a non-dynamic resource, or may mean a start position of a frequency resource or code resource with a non-dynamic resource. An end position for transmission of an uplink data unit may mean an end position (ie, end time position) of a time resource in a non-dynamic resource, or may mean an end position of a frequency resource or code resource with a non-dynamic resource. Embodiments of the present invention are not limited to this. Within the scope of the embodiments of the present invention, exemplary descriptions are given mainly by indicating the start position and the end position being the start position.

position and end time position, respectively. According to the concepts within the embodiments of the present invention, the obtained corresponding technical solutions indicating a start position or an end position for uplink data transmission on a frequency resource or a code resource are included in the scope of the embodiments of the present invention for which protection is claimed.

It should be understood that a non-provisioned scheduling resource may be periodic. For example, a non-provisioning scheduled resource in each period may be multiple contiguous temporary resources or multiple discontinuous temporary resources. Or it can be considered in such a way that the terminal has only one transmission window in each period, while the terminal may perform uplink data transmission on a scheduled resource without allocation of resources in each period. Alternatively, a non-provisioning scheduling resource may be aperiodic. Embodiments of the present invention are not limited to this.

Next, the data transmission method according to the embodiments of the present invention will be described in detail with reference to Embodiments 1-3.

Within Embodiment 1, information for indicating the start position of an uplink data block transmission may be used to indicate whether the first transmission of an uplink data block can be initiated at any non-dynamic resource position.

For example, when a non-provisioned scheduling resource is used to carry latency insensitive services (such as Internet Protocol-based Voice over Internet Protocol (VoIP) services or periodic services), that is, services with low latency requirements, the network device may configure the terminal to initiate the first transmission of an uplink data unit on a specific scheduling resource without resource allocation. Here, a specific non-provisioned scheduling resource may be negotiated by a protocol or pre-installed on a terminal device by a network device. In this case, information for indicating the transmission start position of the uplink data unit may be used to indicate that the first transmission of the uplink data unit cannot be initiated at any non-dynamic resource position, so that the terminal can only initiate the first transmission. uplink data on a specific resource with scheduling without resource allocation.

As another example, when using a scheduling resource without resource allocation to transmit delay-sensitive services, that is, services with high latency requirements, a network device may configure a terminal device to initiate the first transmission of an uplink data unit at any resource position. non-resource-scheduled, so that the terminal can transmit an uplink data block in time, which is advantageous in terms of avoiding non-dynamic resource constraint (eg, limited transmission start position within the resource). In this case, the information for indicating the transmission start position of the uplink data unit may be used to indicate that the first transmission of the uplink data unit can be initiated at any position of the non-dynamic resource.

Thus, in accordance with the communication method of the embodiments of the present invention, a network device may configure a terminal device to initiate the first transmission of an uplink data unit at any non-dynamic resource position or on a specific non-dynamic resource in accordance with the time delay-related requirements of the services. transmitted on a non-dynamic resource, which is useful in meeting the time delay requirements of various services, and may also reduce the difficulty of blindly detecting a network device or may avoid system capacity degradation. For example, for services with high latency requirements, it can be configured such that the first transmission of an uplink data unit can be initiated at any non-dynamic resource position, thus the transmission of an uplink data unit can be made in time and can be improved user experience. For services with low latency requirements, it can be configured such that the first transmission of an uplink data unit can be initiated on a specific non-dynamic resource, so that the initial position configuration can better match the delay-related characteristics of the services, and can be increased flexibility of uplink data transmission.

For convenience of distinction and description, within the scope of embodiments of the present invention, information for indicating the transmission start position of an uplink data unit is referred to as first indication information, that is, the term "first indication information" may denote information for indicating the transmission position of an uplink data unit. . Optionally, within Embodiment 1, one bit for the first indication information may be applied. For example, there may be a configuration such that when the first indication information is 0, this indicates that the first transmission of an uplink data unit cannot be initiated at any non-dynamic resource position, and when the first indication information is 1, this indicates that the first transmission of an uplink data block can be initiated at any non-dynamic resource position. Otherwise, there may be configured inverse features, while the embodiments of the present invention are not limited to this.

Accordingly, the terminal device may initiate the first transmission of the uplink data block according to information configured by the network device to indicate the start position of the transmission of the uplink data block. If an uplink data block needs to be retransmitted, the terminal may perform a subsequent data transmission in accordance with resource patterns having dynamic or pre-configured, or may perform a subsequent transmission using contiguous resources, that is, resources that immediately follow resources for the first transmission are applied for the subsequent transmission. "Continuous" here preferably means continuous in terms of time.

It should be understood that the terminal device performs uplink transmission when there is a service requirement, that is, the terminal device performs uplink transmission according to the above configuration information only when there is a service requirement.

Next, the index mode of the first index information will be described with reference to specific examples shown in FIGS. 3 and 4.

As shown in FIG. 3, the first indication information is used to indicate that the first transmission of an uplink data block can be initiated at any non-dynamic resource position. In this case, the first indication information may be 0, so that it may be implemented such that when the first indication information is 0, it indicates that the first transmission of an uplink data unit cannot be initiated in any the position of a non-dynamic resource. In this case, the tag may initiate the first transmission of an uplink data unit on a specific non-scheduled resource that is part of the non-scheduled resource. For example, an unscheduled resource within a period may include 4 Transmission Time Intervals (TTIs), that is, TTI0, TTI1, TTI4, and TTI5, while a certain unscheduled resource may include TTI0 and TTI4, as indicated by the shaded parts in Fig. 3a. Thus, within a transmission window (i.e., within a resource period with scheduling without resource allocation), a terminal may initiate the first transmission of an uplink data unit at TTI0 or TTI4, but may not initiate the first transmission of an uplink data unit at TTI0 or TTI4. TTI1 and TTI5.

As shown in FIG. 4, the first indication information is used to indicate that the first transmission of an uplink data unit can be initiated at any non-dynamic resource position, in this case, the first indication information may be 1. Thus, it may be is implemented such that when the first indication information is 0, this indicates that the first transmission of the uplink data unit cannot be initiated at any non-dynamic resource position. As shown in FIGS. 3 and 4, a non-scheduled resource in a period may include TTI0, TTI1, TTI4, and TTI5, in which case the terminal may initiate the first transmission of an uplink data unit at any position of the above resource. .

Embodiment 2: Information for indicating the transmission start position of an uplink data unit is used to indicate a position in a resource where the first transmission of an uplink data unit can be initiated in a non-dynamic resource, which is a resource for transmission with non-dynamic scheduling.

Unlike Embodiment 1, within Embodiment 2, the information for indicating an uplink data unit transmission start position may directly indicate a position in a resource where the first uplink data unit transmission can be initiated. Preferably, a bitmap mode for the resource position for the first transmission of the uplink data block may be applied.

For example, when an unscheduled resource is used to carry delay-insensitive services, that is, services with low latency requirements, the network device may configure the terminal device to initiate the first transmission of an uplink data unit within the unscheduled portion of the resource. resource allocation, ie, information for indicating a transmission start position of an uplink data block, may be used to indicate a portion of a non-dynamic resource. Here, the unscheduled resource part may be applied for the first transmission within the unscheduled resource period. In this case, the terminal cannot initiate the first transmission of an uplink data unit at any position of the non-dynamic resource, and can only initiate the first transmission of uplink data within the scheduled non-resource part of the resource.

As another example, when using a scheduled resource without resource allocation to transmit delay-sensitive services, that is, services with high latency requirements, information for indicating the transmission start position of an uplink data unit may be used to indicate the entire non-dynamic resource, wherein the terminal may initiate the first transmission of an uplink data unit at any resource position with scheduling without resource allocation. Thus, when a terminal device needs to transmit delay-sensitive services, the terminal device can transmit an uplink data block in time, which is advantageous in terms of eliminating transmission delay caused by non-dynamic resource constraint (eg, resource transmission start constraint).

Thus, in accordance with the communication method of the embodiments of the present invention, the network device can configure the terminal device to initiate the first transmission of an uplink data unit within the entire non-dynamic resource or part of the non-dynamic resource in accordance with the time delay-related requirements of the services, transmitted on a non-dynamic resource, which is useful in terms of meeting the time delay requirements of various services, and may also reduce the difficulty of blindly detecting a network device or may avoid system capacity degradation. For example, for services with high latency requirements, it can be configured such that the first transmission of an uplink data unit can be initiated at any non-dynamic resource position, thus the transmission of an uplink data unit can be made in time and can be improved user experience. For services with low latency requirements, it can be configured such that the first transmission of an uplink data unit can be initiated within a portion of a non-dynamic resource, so that the initial position configuration can better match the delay-related characteristics of the service, and can to increase the flexibility of uplink data transmission.

Next, the index mode of the first index information will be described with reference to specific examples shown in FIGS. 5 and 6.

As shown in FIGS. 5 and 6, information for indicating the transmission start position of an uplink block, that is, a position within a resource pointed to by the first indication information, can be indicated within a bitmap mode. For example, a non-scheduled resource in a period may include TTI0, TTI1, TTI4, and TTI5, so that the first indication information may be 4 bits indicating whether TTI0, TTI1, TTI4, and TTI5 may be used for the first transmission of an uplink transmission. data block channel, respectively. For example, in FIG. 5, the first indication information may be 1010 such that the terminal initiates the first transmission of an uplink data unit at TTI0 or TTI4, but cannot initiate the first transmission of an uplink data unit at TTI1 and TTI5. As shown in FIG. 6, the first indication information may be 1111 so that the terminal initiates the first transmission of an uplink data block at any position of TTI0, TTI1, TTI4 and TTI5.

Embodiment 3: Information for specifying a transmission end position of an uplink data unit is used to indicate an end position for sending an uplink data unit in a non-dynamic resource.

Within Embodiment 3, the network device may configure information to indicate the transmission end position of the uplink data block. It should be understood that within the framework of this embodiment, that the network device configures a start position for transmitting an uplink data block is not specifically limited within the framework of this embodiment of the invention. Thus, within the scope of the embodiments of the present invention, the network device may only configure a start position for transmitting an uplink data block. Alternatively, the network device may only configure the end position for transmitting the uplink data block. Alternatively, the network device may configure both a start position for transmitting an uplink data unit and an end position for transmitting an uplink data unit.

For convenience of distinction and description, information for indicating the transmission end position of the uplink data unit is referred to as second indication information, that is, the term "second indication information" may be used to indicate the transmission end position of the uplink data unit.

Similar to Embodiment 1, information for indicating the transmission end position of the uplink data unit, that is, the second indication information, may also be used to indicate whether the transmission end position of the uplink data unit is a non-dynamic resource position. For example, the second indication information may be 1 bit. It can be implemented in such a way that if the second indication information is 1, then it indicates that the target position for transmission of the uplink data unit may be any non-dynamic resource position; and if the second indication information is 0, then it indicates that the end position for transmission of the uplink data unit cannot be any non-dynamic resource position. In this case, the end position for uplink data transmission may be a specific position negotiated within the protocol, such as the last TTI in a non-scheduled resource period, or a specific position preset by the network device. The specific implementation process may be performed according to the corresponding description within Embodiment 1, which is not repeated here for the sake of brevity.

Similar to Embodiment 2, information for indicating the transmission end position of the uplink data unit, that is, the second indication information, can also be used to directly indicate the end position for transmission of the uplink data unit. Preferably, the bitmap mode may be adapted for the second indication information to identify which positions are end positions for transmitting an uplink data block in a non-scheduled resource period. As an optional embodiment, the end position for sending an uplink data unit in a non-dynamic resource is the last transmission window in the non-dynamic resource period, and the specific implementation process can be performed as described under Embodiment 2, which is not repeated. here for brevity.

Next, the pointing mode of the second pointing information will be described in detail with reference to a specific example shown in FIG.

For example, the network device specifies for the terminal device that the transmission window is 4 TTI and the transmission interval between two transmission windows is 7 TTI, i.e., the unscheduled resource period is 7 TTI, with the unscheduled resource in each period takes 4 TTI. As shown in FIG. 7, a non-provisioned scheduling resource in a period occupies from TTI0 to TTI3, that is, 4 TTIs in total. Within Embodiment 3, the network device may configure an end position for transmitting an uplink data block, such as the last transmission window in each non-scheduled resource period such as TTI3 or TTI10, and so on. Here, the second indication information may be 0001, which is used to indicate that TTI(7*n+3) is the end positions for uplink data transmission, where n is a non-negative integer and TTI(7 *n+3) may be TTI3, TTI10, and so on. Optionally, the second indication information may be 0, which indicates that the end position for uplink data transmission is a specific position (the specific position here may be the last TTI in a non-scheduled resource period). In this embodiment, the start position for transmitting an uplink data unit is not limited, and may be TTI0 or TTI1 or the like.

If the terminal has data to send in TTI5, then the available and closest transmission resource to TTI5 is TTI7. Alternatively, the terminal may send data in TTI7, TTTI8, TTI9 and TTI10, or when the terminal has data to be sent in TTTI8, the terminal may send data in TTTI8, TTI9 and TTI10.

It should be noted that, within the scope of the embodiments of the present invention, the data unit transmitted before the end position for transmission of the uplink data unit and after the previous end position is the same data unit, namely TTT0~TTI3 if the end position is TTI3 and if a Transmission Block (TB)1 is transmitted in TTT0, then the data block transmitted in TTI0-TTI3 is TB1. That is, TTI3 is the transmission end position of TB1. Even if the transmission of TB1 is successful before TTI3, for example in TTI2, TTI3 is not applied to the transmission of other TBs. Thus, the network device can perform combination processing of the data block received before TTI3. Similarly, within the next transmission window (next resource period in non-provisioning scheduling, eg TTI 7-TTI10), it may be applied to transmit TB2. Before the end position (eg, TTI10), the network device may perform combination processing of the received TB2.

Optionally, in some embodiments, a transmission resource may be included in each non-provisioned scheduling resource period. For example, as shown in FIG. 8, the network device configures the transmission window such that the transmission window occupies 1 TTI and the transmission interval between two transmission windows is 5 TTI, that is, the unscheduled resource period is 5 TTI and the resource with scheduling without resource allocation in each period takes 1 TTI. If the first indication information indicates that the first transmission of an uplink data unit can be sent at any non-resource scheduling resource position, then the terminal may transmit uplink on the transmission resource of each non-allocation period. For example, a terminal may transmit uplink in TTI (5n), where n is a non-negative integer. Or, if the first indication information indicates that the first transmission of the uplink data unit cannot be sent at any non-resource-scheduled resource position, then the terminal may initiate the first transmission of the uplink data unit on the specified resource with scheduling. without allocation of resources, which may be negotiated within the protocol or may be preset by the network device. For example, a certain non-provisioning scheduling resource may be a TTI (10n), where n is a non-negative integer. For the end position for transmitting an uplink data unit, this is similar and will not be re-reported here for brevity.

Embodiment 4: The uplink data block pilot information includes information of at least one root sequence and information of at least one cyclic shift sequence.

Case 1

The at least one root sequence information is root sequence information, the at least one cyclic shift sequence information is multiple cyclic shift sequence information, with different cyclic shift sequences corresponding to different transmission numbers.

In this case, the terminal may determine the cyclic shift sequence corresponding to the transmission number i according to the transmission number i of the uplink data block, and then generate the corresponding pilot sequence according to the root sequence and the cyclic shift sequence, such that the i-th the transmission of the uplink data block may be in accordance with the pilot sequence.

Within this embodiment, the network device may set different sets of cyclic shift sequences (corresponding to the above multiple cyclic shift sequences) for different terminals. By setting sets of cyclic shift sequences of different terminals so as to maintain orthogonality, interference between users can be eliminated, and the network device can identify the transmission number of the uplink data block by determining the cyclic shift sequence of the pilot signal.

Case 2

The at least one root sequence information is multiple root sequence information, the at least one cyclic shift sequence information is cyclic shift sequence information, and different root sequences correspond to different transmission numbers.

In this case, the terminal may determine the root sequence corresponding to the transmission number i according to the transmission number i of the uplink data block, and then generate the corresponding pilot sequence according to the root sequence and the cyclic shift sequence, such that the i-th transmission of the uplink data block may be implemented in accordance with the pilot sequence.

Within this embodiment, the network device may set different sets of root sequences (corresponding to the above-mentioned multiple root sequences) for different end devices. The root sequence sets of different terminals have a low correlation, thus interference between users can be eliminated, and the network device can identify the transmission number of the uplink data block by determining the root sequence of the pilot signal.

It should be noted that some or all of the above sequence information (the root sequence and the cyclic shift sequence) remains unchanged during data transmission, or some or all of the above sequence information is sequence information at a certain point. At other times, the information of the root sequence and the cyclic shift sequence may be obtained in accordance with other rules, while the embodiments of the present invention are not limited to them.

For example, in TTI0, the cyclic shift sequence corresponding to the first through the fourth gear is [0, 1, 2, 3]. According to the pilot frequency modulation rule, CSj=CS(j-1)+shift; shift=2, where CSj means pilot signal j and shift means the shift between two adjacent pilot signals, then it can be determined that in TTI1, the cyclic shift sequence corresponding to the first through the fourth gear is [2, 3, 4, 5] ; in TTI2, the cyclic shift sequence corresponding to the first through the fourth gear is [4, 5, 6, 7]; and in TTI3, the cyclic shift sequence corresponding to gears one through four is [6, 7, 8, 9].

In other words, information for indicating a transmission end position of an uplink data unit is shared among multiple cells, or is dedicated to a cell. Or, the information for configuring the pilot for transmission of an uplink data block is shared among multiple serving cells, or is dedicated to a serving cell.

In other words, the network device may set the same first indication information for multiple serving cells, i.e., several serving cells may set the same start position for transmission of the uplink data block, or the network device may independently set the corresponding first indication information for each serving cell. In other words, the network device may set the same first indication information for multiple serving cells in the same manner, or may independently set the corresponding first indication information for each serving cell within the plurality of serving cells, respectively. This is similar to information for indicating the end position of transmission of an uplink data unit and information for configuring a pilot signal for transmission of an uplink data unit, and will not be re-described here for brevity.

Otherwise, the end position information for transmitting an uplink data unit is configured to be shared among multiple non-dynamic resources, or is configured for a non-dynamic resource.

In other words, information for configuring a pilot for transmitting an uplink data unit is configured to be shared among multiple non-dynamic resources, or is configured for a non-dynamic resource.

In particular, if each serving cell is configured with multiple non-dynamic resources, then the network device may configure multiple non-dynamic resources to match one first indication, i.e., the terminal may transmit uplink on multiple non-dynamic resources and may use the same starting position. Or, the network device may configure each non-dynamic resource within multiple non-dynamic resources to match the corresponding first indication information, i.e., the terminal may transmit uplink on a particular non-dynamic resource and may use the start position corresponding to the non-dynamic resource. In other words, the network device may set the same first indication information for multiple non-dynamic resources in the same way, or may independently set the corresponding first indication information for each non-dynamic resource within the multiple non-dynamic resources, respectively. This is similar to information for indicating the end position of transmission of an uplink data unit and information for configuring a pilot signal for transmission of an uplink data unit, and will not be re-described here for brevity.
