Description

Uplink control signal scheduling and transmission method and device

This application claims the priority of the Chinese Patent Application, filed on Jan. 6, 2017, the application Serial No.

Technical field

The present application relates to the field of wireless communications technologies, and in particular, to an uplink control signal scheduling and transmission method and device.

Background technique

In the existing Long Term Evolution (LTE) system, the time domain of the uplink control channel is fixed, and the real-time domain occupies 14 symbols, as shown in FIG. 1 . Therefore, no additional indication signaling is needed to indicate the time domain resources occupied by the terminal uplink control channel. In a Frequency Division Duplexing (FDD) system, the subframe occupied by the uplink control signal is the fourth subframe after the subframe of the corresponding downlink data transmission.

However, in the future 5G, there are multiple types of subframes or time slots, and the number of symbols included in each subframe or time slot may be different, and resources for uplink control signal transmission in different subframes or time slots may also be different. The sub-frames shown in FIG. 2( a ) are sub-frames mainly based on the following lines, wherein the resources that can be used for uplink transmission are resources corresponding to the last few symbols, and the resources corresponding to the remaining symbols are downlink transmission resources and upper and lower. The transmission interval gap is as follows: the subframe shown in FIG. 2(b) is the subframe in which the uplink transmission is the primary, wherein the resources corresponding to the first few symbols are the downlink transmission resource and the uplink and downlink transmission interval gap, and the remaining symbols. The uplink transmission resource; the subframe shown in FIG. 2(c) is a subframe in which all resources are used for uplink transmission.

In the 5G, according to the duration of the uplink control signal transmission, the uplink control channel can be divided into a long duration PUCCH and a short duration PUCCH. The short duration PUCCH usually contains 1 to 2 symbols, and the Long duration PUCCH usually contains no less than 4 symbols.

Therefore, the method for transmitting an uplink control signal at a fixed position after the corresponding downlink data transmission subframe in the prior art cannot cope with the requirement for transmitting the uplink control signal in the more flexible subframe type in the 5G.

detailed description

The embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

In the future 5G, since the types of subframes or time slots are various, the number of symbols included in each subframe or time slot can be Differently, resources for uplink control signal transmission in different subframes or time slots may also be different. Therefore, the method for transmitting an uplink control signal at a fixed position after the corresponding downlink data transmission subframe in the prior art cannot cope with the requirement for transmitting the uplink control signal in the more flexible subframe type in the 5G.

In order to solve the above problem, an embodiment of the present invention provides a method and a device for scheduling and transmitting an uplink control signal, so as to enable a network device to flexibly schedule a resource for transmitting an uplink control signal for a terminal, where the terminal is scheduled according to the network device. The uplink control signal is sent on the resource.

FIG. 3 is a schematic flowchart of a method for scheduling and transmitting an uplink control signal according to an embodiment of the present invention. As shown in the figure, the method includes the following steps:

Step 301: The network device determines the first information, where the first information is used to indicate that the terminal sends at least one subframe or time slot occupied by the uplink control signal.

In a possible implementation manner, the first information indicates a manner in which the terminal sends the subframe or the time slot occupied by the uplink control signal, and may be one of the following manners.

In the first mode, the first information includes each subframe or time slot occupied by the terminal sending the uplink control signal.

In a specific embodiment, the first information may include a subframe number allocated by the network device for each subframe of the uplink control signal, or a slot number of each time slot, so that the terminal can It is clear in which subframes or on which time slots the uplink control signal is sent.

The method can be applied to a network device to allocate a continuous or non-contiguous subframe or time slot for transmitting an uplink control signal to the terminal.

The mode 2 includes the initial subframe or time slot occupied by the terminal sending the uplink control signal.

In a specific embodiment, the first information may include a subframe number allocated by the network device for the terminal to send the uplink control signal, or a slot number of the start time slot. For example, if the first information includes the time slot 3, the terminal can explicitly send the uplink control signal from the time slot 3, and continue to transmit the uplink control signal on the time slot after the time slot 3 that can transmit the uplink control signal; Transmitting the uplink control signal from the last time slot of the time slot indicated by the first information, the terminal explicitly transmits the uplink control signal from time slot 4, and the subframe or time after the time slot 4 can transmit the uplink control signal The uplink control signal continues to be transmitted on the slot.

The method is applicable to the network device to allocate consecutive or non-contiguous subframes or time slots for transmitting the uplink control signal to the terminal. Since the amount of information carried is small, the number of bits of the first information can be saved, and the signaling overhead is reduced.

Mode 3: The first information includes an offset of at least one subframe or time slot occupied by the terminal sending the uplink control signal.

Taking the offset of the time slot included in the first information as an example, the offset of the time slot may have the following two forms:

1) As shown in offset1 and offset2 shown in FIG. The offset of the start time slot is the offset between the start time slot and the time slot occupied by the corresponding downlink control signal (ie, offset1), and the offset of the non-start time slot is the time slot. The offset from the previous time slot for transmitting the uplink control signal (ie, offset2).

2) As shown in offset 1' and offset 2' shown in Fig. 4. The offset of each time slot used for transmitting the uplink control signal is the offset between the time slot and the time slot occupied by the corresponding downlink control signal.

In some cases, if the offset between each subframe or time slot is the same, the first information may also include the offset of the starting subframe or the time slot, then the non-starting subframe and the previous one are used. The offset between the subframes in which the uplink control signal is transmitted is the same as the offset between the subframe in which the initial subframe and the corresponding downlink control signal are occupied. The first information may also include indication information indicating that all offsets are the same, or the network device and the terminal have previously agreed that all offsets are the same.

The method can also be applied to a network device to allocate a continuous or non-contiguous subframe or time slot for transmitting an uplink control signal to the terminal. Since the offset is less than the amount of information required by the subframe number or the slot number, it can be carried. Less information, saving the number of bits of the first information and reducing signaling overhead.

Mode 4: The first information includes an offset of a starting subframe or a time slot occupied by the terminal sending the uplink control signal.

The offset of the start subframe is the offset between the start subframe and the subframe occupied by the corresponding downlink control signal, and the offset of the start slot is the start slot and the corresponding downlink control signal. The offset between the occupied time slots.

For example, the first information includes an offset between the time slot 3 and the time slot occupied by the corresponding downlink control signal, and the terminal may start sending the uplink control signal from the time slot 3, and after the subframe or the time slot 3 The uplink control signal may continue to be transmitted on the subframe or the time slot in which the uplink control signal can be transmitted.

The method can also be applied to the network device to allocate consecutive or non-contiguous subframes or time slots for transmitting the uplink control signal to the terminal. The number of bits of the first information can be saved and the signaling overhead can be reduced because the amount of information carried is small. .

Step 302: The network device sends the first information to the terminal.

In a possible implementation manner, the network device may send the first information to the terminal by using Downlink Control Information (DCI), Radio Resource Control (RRC) signaling, or cell broadcast signaling.

Further, the network device may send the information of the subframe or the time slot for instructing the terminal to send the uplink control signal to the terminal, and may also include the number of symbols included in each subframe or time slot, and each subframe or time slot. The number of symbols that can be used for uplink transmission is sent to the terminal, which is not limited in this application.

Step 303: The terminal sends an uplink control signal on a subframe or a time slot indicated by the first information.

In the prior art, the terminal sends an uplink control signal on a fixed fourth subframe after the subframe of the corresponding downlink data transmission. However, in the future 5G scenario, the number of symbols included in each subframe or slot is different. The number of symbols that can be used for uplink transmission in each subframe or time slot is also different, and the uplink control signal cannot be transmitted on a fixed time domain resource. In the foregoing embodiment of the present invention, the network device sends information about a subframe or a time slot for instructing the terminal to send an uplink control signal to the terminal, so as to implement flexible scheduling of corresponding resources for the uplink control signal of the terminal.

In some embodiments, if the network device only sends the first information to the terminal, that is, the network device only informs the terminal in which subframes or which time slots to send the uplink control signal, the terminal may default to the first information indicated by the first information. All of the subframes or time slots can be used to transmit uplink control signals on the symbols of the uplink transmission.

However, when different terminals or the same terminal are in different environments, the time required to transmit the uplink control signal is different. If the duration required for the terminal to send the uplink control signal is small, it may not need to occupy all the uplink transmission resources in one subframe or one time slot; if the terminal needs to send the uplink control signal for a longer period of time, in multiple subframes or times The duration of the uplink control signal sent in the slot may be the same or different. Therefore, the network device may further indicate the duration of time that the terminal takes to send the uplink control signal on each subframe or time slot.

Therefore, in other embodiments, the network device may further determine the second information, where the second information is used to indicate that the terminal sends the uplink on the subframe or the time slot indicated by the first information, in addition to transmitting the first information to the terminal. Controls the duration of the signal and sends the second message to the terminal. Referring to FIG. 5, it is a schematic flowchart of the embodiment. As shown in the figure, the following steps are included:

Step 501: The network device determines the first information and the second information. The first information is used to indicate at least one subframe or time slot occupied by the terminal to send the uplink control signal, and the second information indicates the duration of time that the terminal uses to send the uplink control signal in the subframe or time slot indicated by the first information.

The first information indicates the manner in which the terminal sends at least one subframe or time slot occupied by the uplink control signal, as described above, and details are not described herein again.

The length of time required for the terminal to send the uplink control signal is related to the channel quality of the terminal, for example, the distance from the terminal to the network device, and whether there is an obstacle between the terminal and the network device. Generally, the farther the distance between the terminal and the base station is, the better the channel quality is, and the more time the terminal needs to send the uplink control signal; the closer the distance is, the better the channel quality is and the less time is required.

In the scenario of 15 kHz subcarrier spacing, the terminal may need 1 to 14 symbols to transmit the uplink control signal (the duration of 14 symbols is 1 ms). As shown in Figure 6, as the distance between the terminal and the network device increases, The more symbols are required to transmit the uplink control signal. In the scenario of larger subcarrier spacing, the terminal may need more symbols to send uplink control signals.

For the foregoing reasons, in a possible implementation manner, the network device may determine, according to the channel quality of the terminal, a duration that the terminal needs to use to send the uplink control signal. Specifically, the network device may determine, in a manner, how long the terminal needs to use to send an uplink control signal:

Mode 1, the network device can measure the channel quality of the terminal, and determine the duration of time for transmitting the uplink control signal allocated by the terminal according to the channel measurement result.

Mode 2: The network device may further determine, according to the received channel measurement report sent by the terminal, a duration occupied by the uplink control signal allocated by the terminal.

Mode 3: The terminal may report the number of symbols that the uplink control signal sent by the terminal needs to be occupied by the network device, and the network device determines, according to the number of symbols reported by the terminal, the duration of time for transmitting the uplink control signal allocated by the terminal.

Mode 4: The terminal may report the range of the number of symbols that the uplink control signal sent by the terminal to the network device, or the maximum or minimum value of the required symbol, and the range of the number of symbols reported by the network device according to the terminal, or the maximum value of the symbol. Or the minimum value, determining the length of time that the terminal allocates the uplink control signal.

The network device determines, in one of the foregoing manners, the total duration of time that the uplink control signal is allocated for the terminal, and further determines the duration of time occupied in each subframe or each time slot.

In a possible implementation, the network device and the terminal may pre-arrange to transmit the uplink control signal by default from the first symbol on the resource that can be used for uplink transmission in one subframe or time slot, or to stipulate from other locations. The symbol begins to transmit the upstream control signal. In this case, the second information may include the number of symbols used by the uplink control signal in at least one subframe or time slot of the subframe or the time slot indicated by the first information, or the time during which the uplink control signal is sent. In order for the terminal to know which symbols are occupied in the subframe or the time slot, the uplink control signal is sent. For example, the first information indicates slot 1 and slot 2 for transmitting the uplink control signal, and the second information indicates only the duration of transmitting the uplink control signal on slot 1; then the terminal can be based on slot 1 The duration indicated by the second information sends an uplink control signal, and the uplink control signal is sent on all resources available for transmitting the uplink information on the slot 2. In addition, for a subframe or a time slot in which different uplink control signal transmission durations are allocated, the start symbol of the agreed default transmission uplink control signal may also be different. For example, if the network device instructs the terminal to occupy 10 symbols to transmit the uplink control signal on the time slot 1, and to occupy the uplink control signal by occupying 1 symbol on the time slot 2, the terminal may be in the time slot 1 according to the pre-determination with the network device. The first to tenth symbols that can be used for uplink transmission send an uplink control signal, and the last symbol that can be used for uplink transmission on slot 2 transmits an uplink control signal.

Alternatively, the network device and the terminal may pre-arrange to start transmitting the uplink control signal in a subframe or a time slot by default. In this case, the second information may include at least one subframe in the subframe or the slot indicated by the first information. Or the time during which the uplink control signal is sent on the time slot, so that the terminal can start at the agreed start time on the subframe or time slot. The uplink control signal is transmitted within the above duration. As described above, the start time of the default transmission uplink control signal may be different according to the subframe or the time slot to which the different uplink control signal transmission durations are allocated.

In another possible implementation manner, the second information may include a number of all symbols occupied by the uplink control signal in one subframe or a time slot, so that the terminal knows which symbols are occupied on the subframe or the time slot. Send an uplink control signal. In this manner, the network device and the terminal do not have to pre-arrange the starting position of the uplink control signal, or the network device can notify the terminal to use the uplink control signal when the initial start signal is not feasible. symbol.

The following describes the content of the second information by taking the number of symbols occupied by the uplink control signal in one subframe or time slot as an example.

According to the duration of the uplink control signal transmission in a subframe or a time slot, it can be divided into a Long duration PUCCH and a Short duration PUCCH, where the Short duration PUCCH usually includes 1 to 2 symbols, and the longer than 3 symbols are usually Long duration PUCCH. .

However, in order to reduce the complexity of the scheduling and the complexity of the transmission pattern of the uplink control signal, a partial form may be selected from a plurality of combinations of Long duration PUCCH and Short duration PUCCH for transmission of the uplink control signal. For example, a Short duration PUCCH of 1 symbol, a Short duration PUCCH of 2 symbols, a Long duration PUCCH of 4 symbols, a Long duration PUCCH of 7 symbols, and a Long duration PUCCH of 14 symbols may be selected as the uplink control signal for scheduling. The format, that is, when the network device allocates one subframe or time slot for the terminal to transmit the uplink control signal, only selects from the above duration.

As mentioned above, in the scenario of 15 kHz subcarrier spacing, the terminal may need 1 to 14 symbols to send uplink control signals. The number of symbols included in the subframe or time slot allocated by the network device for the terminal is greater than or equal to the number of symbols required by the terminal. The strategy for the symbol that the terminal needs to send the uplink control signal and the uplink control signal that the network device allocates for the terminal can be as shown in Table 1.

Table 1

In Table 1, the network device sets a corresponding policy for each value of the number of symbols that the terminal may need to implement the resource utilization efficiency as much as possible, but the complexity increases accordingly, and the network device may send the policy to the terminal. This causes a large signaling overhead. Therefore, Table 1 can also be simplified. After simplification, the symbols required for the terminal to send the uplink control signal and the network device to allocate the scheduling policy for the terminal are shown in Table 2.

Table 2

The policies of the uplink control signals allocated by the network device to the terminal in Table 1 and Table 2 are Short duration PUCCH with 1 symbol, Short duration PUCCH with 2 symbols, Long duration PUCCH with 4 symbols, Long with 7 symbols. The duration PUCCH and the 14-symbol Long duration PUCCH are taken as an example. Of course, other forms of Long duration PUCCH or Short duration PUCCH can also be used, as shown in Table 3.

table 3

In the future 5G, the subcarrier spacing may be different from the subcarrier spacing used in the prior art. As the subcarrier spacing becomes larger, the shorter the duration of one symbol, the more the number of symbols included in the same duration. For example, in the case of a subcarrier spacing of 15 kHz, 1 ms contains 14 symbols; in the case of a subcarrier spacing of 60 kHz, 1 ms contains 56 symbols. Therefore, in the future 5G, if the duration of the terminal to transmit the uplink control signal does not change, the number of symbols that need to be occupied may be greater than 14 symbols.

Therefore, when the number of symbols required by the terminal is greater than 14, the policy of the uplink control signal allocated by the network device to the terminal may be as shown in Table 4.

Table 4

Certainly, the policy of the uplink control signal allocated by the network device shown in the foregoing Tables 1 to 4 is only an example provided by the embodiment of the present invention. In actual application, the policy of the uplink control signal allocated by the network device to the terminal may include: However, it is not limited to the form of the above strategy, and the present application does not limit this.

After determining the policy of the uplink control signal allocated to the terminal, the network device determines the specific content included in the second information. The second information may specifically include the duration of time that the terminal sends the uplink control signal in each subframe or time slot in the subframe or the time slot indicated by the first indication information, or may also include the terminal to send the uplink control. Signal strategy.

For example, if the policy of the uplink control signal allocated by the network device to the terminal is to use two “Long Symbol PUCCHs of 7 symbols”, the content included in the second information may be on each subframe of the two subframes indicated by the first information. , occupying 7 symbols. For example, the policy of the uplink control signal allocated by the network device for the terminal may be numbered, and each index value corresponds to the foregoing one policy. When the network device allocates an uplink control signal for the terminal, the strategy is to use two “7 symbols”. In the Long duration PUCCH, the second information only needs to include the index value of the policy, reducing the number of bits of the second information, and saving signaling overhead.

If the second information includes an index value of a policy of the uplink control signal allocated by the network device to the terminal, the network device may send the correspondence between the index value and the policy of the uplink control signal allocated by the network device to the terminal in advance to the terminal. Therefore, the terminal quickly obtains the corresponding policy by querying the corresponding relationship, that is, the duration of sending the uplink control signal in each subframe or time slot.

Specifically, the network device may send, by using DCI signaling, RRC signaling, or cell broadcast signaling, a correspondence between a subframe index value and a policy of an uplink control signal allocated by the network device to the terminal to the terminal.

Step 502: The network device sends the first information and the second information to the terminal.

In some embodiments, the network device may carry the first information and the second information in the same signaling to send to the end. For example, the network device may carry the first information and the second information in the same DCI, RRC, or cell broadcast signaling to the terminal.

In other embodiments, the network device may also send the first information and the second information to different terminals in different signaling. As mentioned before, the network device can send the first information to the terminal through DCI, RRC or cell broadcast signaling. The network device may also send the second information to the terminal by using DCI, RRC or cell broadcast signaling.

Step 503: The terminal sends an uplink control signal on a subframe or a time slot indicated by the first information according to the duration indicated by the second information.

For a clear understanding of the uplink control signal scheduling and transmission method provided by the embodiment of the present invention, the following describes the specific embodiments.
