Description

Method and device for transmitting scheduling request

Technical field

The embodiments of the present invention relate to, but are not limited to, the field of wireless communications, and in particular, to a method and an apparatus for transmitting a scheduling request (SR).

Background technique

MPC (Machine Type Communication) or Machine to Machine (UE) is the main application form of the Internet of Things. Low power/low cost is an important guarantee for its reachable scale. The M2M devices currently deployed on the market are mainly based on the Global System of Mobile Communication (GSM) system. In recent years, due to the higher spectral efficiency of Long Term Evolution (LTE) systems, and more and more mobile operators have determined the evolution direction of LTE as a future broadband wireless communication system, M2M multi-class data based on LTE The business will also be more attractive.

The cost of the UE (including the MTC UE) is mainly from two parts: the baseband processing part and the radio frequency part. In order to reduce the cost of the MTC UE, reducing the uplink and/or downlink transmission bandwidth of the UE (including the baseband bandwidth and the radio frequency bandwidth) is a very effective way to reduce the cost of the MTC UE, for example, setting the uplink and/or of all the MTC UEs. The downlink transmission bandwidth can only be narrowband bandwidth such as 1.4 megahertz (MHz) (even if the system bandwidth is much longer than 1.4 MHz). In addition to the above method for reducing the transmission bandwidth, the cost of the MTC UE can be reduced by using a single receiving antenna, reducing the transmission power, and reducing the maximum transport block size (TBS, Transport Block Size).

Since some MTC UEs are installed in the basement of a home or are obscured by aluminum alloy windows or traditional thick-walled building structures, these UEs experience considerable penetration loss on the RF interface compared to normal MTC UEs. Therefore, in order to ensure normal data transmission of such UEs, it is necessary to enhance the coverage of the MTC UE. The channel types that need to be enhanced are: physical uplink or downlink shared channel (PUSCH/PDSCH, Physical Uplink/Downlink Shared Channel) and physical uplink or downlink control channel (PUCCH/PDCCH, Physical Uplink/Downlink Control Channel). Among them, the coverage enhancement of the PDSCH includes a system information block (SIB, System). Information Block) Coverage enhancement of data, paging messages, and coverage enhancement of unicast service data. To accumulate more energy to improve coverage, repeated methods are often used to achieve transmission enhancements for various channel types.

Related Art The PUCCH in the LTE system is used to carry Uplink Control Information (UCI); wherein the UCI includes: Hybrid Automatic Repeated Request (HARQ) acknowledgement (ACK, Acknowledgement) or non-acknowledgement (NACK) , Negative Acknowledgement, SR, and Channel State Information (CSI). The method for transmitting a scheduling request by a related art generally includes: an eNB (Evolved Node B) and a terminal transmitting and attempting to receive an SR at a determined subframe interval, that is, an uplink subframe for SR transmission is The determined subframe interval occurs periodically. In the related art transmission scheduling request method, when the transmission signal to noise ratio is low, the eNB cannot accurately receive the SR. The related technology does not give a good solution to enhance the coverage of SR.

Table 1

The acquiring the first transmission parameter of the SR according to the coverage enhancement level of the SR includes: searching for a first transmission parameter corresponding to the coverage enhancement level of the SR in a correspondence between the coverage enhancement level of the preset SR and the first transmission parameter. For example, before acquiring the first transmission parameter of the SR according to the coverage enhancement level of the SR, different SR coverage enhancement levels and different SR first transmission parameters may be paired with each other to make any SR coverage enhancement level and unique SR first transmission. The parameters correspond.

Wherein, TIN_1 a time interval for the first number, O _SR bias the first transmission parameters.

2(a) is a schematic diagram of dividing all time intervals in the scheduling period P _SR into P _SR /N _SR time interval blocks. As shown in FIG. 2, in the method for determining the time interval, all the time intervals in each scheduling period P _SR are divided into P _SR /N _SR time interval blocks, and each time interval block includes N _{SR .} a time-continuous time intervals, so that, depending on the value assigned O _SR, a UE may select all of the above SR transmission repeat time interval partitioned blocks; by different UE allocated different _SR values O, the UE different The SR can be repeatedly transmitted using different time interval blocks, and the base station can also block and receive the SRs sent by different UEs in different time intervals. This method has the benefit of lower implementation complexity and smaller transmission delay.

Alternatively, the terminal divides all time intervals in the scheduling period P _SR or K _SR N _SR in the first transmission parameter into K _SR or P _SR /N _SR time interval blocks; wherein each time interval block includes N _SR time-discontinuous time intervals, and the time interval between two adjacent time intervals is K _SR or P _SR /N _SR ; the terminal determines that the time interval for transmitting the SR is K according to the offset in the first transmission parameter _{One of SR} or P _SR /N _SR time interval partitions; wherein, P _SR is a scheduling period in the first transmission parameter, N _SR is the number of repetitions in the first transmission parameter, and K _SR is the first transmission parameter Repeated transmission interval.

Where K _SR is the repeated transmission interval in the first transmission parameter.

Alternatively, the terminal determines the first time interval according to the formula (3), and determines that the time interval in which the SR is transmitted is the N _SR time intervals in which the time from the first time interval is discontinuous.

The time interval between two adjacent time intervals may be P _SR /N _SR .

TIN_1mod(K _SR N _SR )=O _SR (3)

Wherein O _SR is any one of 0 to (K _SR -1).

2(b) is a schematic diagram of dividing all time intervals in the scheduling period P _SR or K _SR N _SR into P _SR /N _SR or K _SR time interval blocks. As shown in FIG. 2(b), in the method for determining the time interval, all the time intervals in each scheduling period are divided into P _SR /N _SR or K _SR time interval blocks, and each time interval is divided into blocks. Including N _SR uniformly distributed and time discontinuous time intervals, and the time interval of two adjacent time intervals is P _SR /N _SR or K _SR , and depending on the value of O _SR , the UE may select all the time interval blocks mentioned above. One of the repeated transmissions of the SR; by assigning different _OSR values to different UEs, different UEs may repeatedly transmit SRs using different time interval blocks, and the base station may also block and receive different UEs to transmit in different time intervals. SR. The method provides sufficient time diversity gain, reduces the number of repetitions required in the scheduling period, and reduces the corresponding control overhead; when the HARQ-ACK repeated transmission takes up a continuous time interval, the SR repeats transmission at this time. It is occupied by a discontinuous time interval, so SR and HARQ-ACK may not share the same number of repeated transmissions.

Alternatively, the terminal divides all time intervals in the scheduling period P _SR in the first transmission parameter into P _SR /(K _SR N _SR ) scheduling areas; wherein each scheduling area includes K _SR N _SR time continuous time Interval; the terminal divides all time intervals in each scheduling area into K _SR time interval blocks; wherein each time interval block includes N _SR time discontinuous time intervals, and adjacent two time intervals The time interval between the two is K _SR ; the terminal determines, according to the offset in the first transmission parameter, that the time interval for transmitting the SR is one of P _SR /N _SR time interval blocks.

The time interval between two adjacent time intervals may be K _SR .

TIN_1mod P _SR =O _SR,1 K _SR N _SR +O _SR,2 (4)

Wherein, O _{SR, 1} is any integer from 0 to P _SR /(K _SR N _SR )-1, and O _{SR, 2} is any one of 0 to (K _SR -1).

2(c) is a schematic diagram of dividing all time intervals in the scheduling period P _SR into P _SR /(K _SR N _SR ) scheduling areas. As shown in FIG. 2(c), in the method for determining the time interval, all time intervals in each scheduling period are divided into P _SR /(K _SR N _SR ) scheduling areas, and each scheduling area includes K _SR. N _SR time intervals, all time intervals in each scheduling area are divided into K _SR time interval blocks, each time interval block includes N _SR uniformly distributed time discontinuous time intervals, and adjacent two The interval of time intervals is K _SR , depending on the assigned O _{SR, 1} and O _{SR, 2} values, the UE may select one of the above all time interval blocks to repeatedly send SR; by assigning different O _SRs to different UEs _{1, 1} and O _{SR, 2} take values, different UEs may repeatedly transmit SRs using different time interval blocks in the same or different scheduling areas, and the base station may also block in different time intervals in the same or different scheduling areas. The UEs are combined to receive SRs sent by different UEs.

The method has a relatively small time diversity gain, but reduces the transmission delay of the SR to a certain extent, thereby achieving a balance between control overhead and delay; when the HARQ-ACK repeated transmission takes up a continuous time interval, Since the SR repeated transmission at this time is occupying a discontinuous time interval, Therefore, SR and HARQ-ACK may not share the same number of repeated transmissions.

If the UE has a valid PUCCH format 1 resource for the SR and has not received the UL-SCH resource grant information from the base station, the number of SR scheduling cycles experienced by the UE repeatedly transmitting the SR is less than the maximum allowed (predefined or When the RRC parameter indication from the base station is used, the UE continues to send the SR signal on one of the above-mentioned all SR repeated transmission modes on the configured PUCCH format 1 resource; when the SR scheduling period is greater than or equal to the allowed maximum value, Initiate a random access procedure.

It should be emphasized that, in the repeated transmission modes of all the foregoing SRs, the N _SR time intervals of the transmitting SR periodically occur at intervals of the scheduling period P _SR .

Alternatively, the terminal divides all time intervals into K _SR time interval groups; wherein each time interval group includes a time interval in which the time is not continuous, and the time interval between two adjacent time intervals is K _SR ; The offset in a transmission parameter determines that the time interval in which the _SR is transmitted is one of K _SR packets; wherein K _SR is the repeated transmission interval in the first transmission parameter.

Wherein, determining, according to the offset in the first transmission parameter, that the time interval for transmitting the SR is one of K _SR groups includes:

The terminal determines the time interval for transmitting the SR according to formula (5).

The time interval between two adjacent time intervals may be K _SR .

TIN mod K _SR =O _SR (5)

Wherein O _SR is any one of 0 to (K _SR -1).

Where TIN is the number of the time interval in which the SR is transmitted.

Figure 2(d) is a schematic diagram of dividing all time intervals into K _SR packets. As shown in FIG. 2(d), in the method for determining the time interval, all time intervals are divided into K _SR time interval groups, and each group includes N _SR uniformly distributed time discontinuous time intervals, and The time interval between two adjacent time intervals is K _SR . Depending on the value of the allocated O _SR , the UE may select one of all time interval packets to continuously transmit the SR. By assigning different _OSR values to different UEs, different The UE may continuously transmit the SR by using different time interval packets, and the base station may also combine and receive the SRs sent by different UEs in different time intervals.

If the UE has a valid PUCCH format 1 resource for the SR and has not received it yet To the UL-SCH resource grant information from the base station, when the number of times the UE continuously transmits the SR is less than the maximum allowed value (predefined or indicated by the RRC parameter from the base station), the UE continues to be on the configured PUCCH format 1 resource. The SR repeat transmission mode transmits the SR signal; when the number of times the UE continuously transmits the SR is greater than or equal to the maximum allowed value, the random access procedure is initiated.

When the duration of the SR sent by the terminal exceeds the scheduling period in the M first transmission parameters, and the uplink grant from the base station is not received, where M is a positive integer greater than or equal to 1 and M is based on indication signaling from the base station Or determined according to the coverage enhancement level of the SR.

The determining, by the M, the coverage enhancement level of the SR includes: searching for the M corresponding to the coverage enhancement level of the SR in a correspondence between the preset M and the coverage enhancement level of the SR.

The coverage enhancement level of the SR corresponding to each M in the corresponding relationship may be one or more. For example, before determining M according to the SR coverage enhancement level, different SR coverage enhancement levels and different M values may be paired with each other such that any M value corresponds to at least one SR coverage enhancement level; thus, according to SR coverage The enhancement level makes it easy to determine the value of M.

Optionally, the method further includes:

Step 102: The terminal acquires a second transmission parameter of the SR. The terminal determines a time interval for transmitting the SR according to the second transmission parameter of the SR, and repeatedly sends the SR in the determined time interval. The UE automatically determines the time interval for transmitting the SR according to the second transmission parameter of the SR and repeatedly transmits the SR within the determined time interval, thereby preventing the base station from reallocating or indicating new transmission parameters to the UE, or avoiding unnecessary randomization. The access process reduces the SR transmission delay.

In this step, before the terminal acquires the second transmission parameter of the SR, the method further includes: receiving, by the terminal, signaling from the base station to adjust the transmission parameter of the SR. At this time, the function of the terminal adjusting the transmission parameter (ie, determining the time interval for transmitting the SR according to the second transmission parameter) is an optional or optional function of the terminal, that is, only the terminal receives the indication from the base station to adjust the transmission of the SR. The signaling of the parameters will be enabled by the terminal.

In this step, in order to ensure that the coverage performance of the SR transmitted according to the second transmission parameter is not lower than the coverage performance of the SR according to the first transmission parameter, the scheduling period in the first transmission parameter may be made smaller than the scheduling period in the second transmission parameter. And/or, the repeated transmission interval in the second transmission parameter is smaller than the repeated transmission interval in the first transmission parameter, and/or the number of repetitions in the first transmission parameter is less than The number of repetitions in the second transmission parameter.

In this step, the second transmission parameter and the first transmission parameter have the same parameter set, but the values are different. The terminal obtains the first transmission parameter and the second transmission parameter of the SR at different times, and how the terminal obtains the second transmission parameter of the SR may be the same as the process of acquiring the first transmission parameter of the SR by the terminal, but only obtaining the obtained transmission parameter. The values are different.

Or the acquiring, by the terminal, the second transmission parameter of the SR includes: acquiring, by the terminal, the second transmission parameter according to the first transmission parameter. The base station indicates in a differential manner based on the first transmission parameter, that is, the indication signaling from the base station carries a change value of at least one of the second transmission parameters with respect to the first transmission parameter. For example, it may be defined that the scheduling period or the number of repetitions in the second transmission parameter is always the first of all available values that are greater than the scheduling period or number of repetitions in the first transmission parameter.

In this step, the time interval determined according to the second transmission parameter is a time interval that is continuous or discontinuous.

In this step, how the terminal determines, according to the second transmission parameter of the SR, that the time interval for transmitting the SR is the same as the process for determining, by the terminal, the time interval for transmitting the SR according to the first transmission parameter of the SR.

Referring to FIG. 3, an embodiment of the present invention further provides a method for transmitting an SR, including:

Step 300: The base station acquires a first transmission parameter of the SR.

In this step, the first transmission parameter includes at least an offset, a scheduling period, and/or a repeated transmission interval. That is, the first transmission parameter includes an offset and a scheduling period, or includes an offset and a repetition transmission interval, or includes an offset, a scheduling period, and a repeated transmission interval. The first transmission parameter may further include a repetition number. It can be said that the first transmission parameter of the SR includes all transmission parameters related to the determination of the SR repeat transmission time domain resource.

The scheduling period, or the offset, or the repeated transmission interval, or the number of repetitions includes an integer number of time intervals, that is, in units of time intervals.

The scheduling period is greater than or equal to the number of repetitions. This enables SR repeated transmissions within the SR scheduling period, thereby ensuring the performance of SR repeated transmissions within the SR scheduling period.

The scheduling period may also be referred to as a merging period, that is, a time interval interval indicating that the base station is adjacently received and received the repetitive transmission SR. The retransmission interval is when the repeated transmission of the SR is a time interval in which the occupation time is discontinuous. The number of time intervals between two adjacent time intervals; the number of repetitions refers to the number of time intervals occupied by repeated transmission of SRs.

In this step, the first transmission parameter of the base station acquiring the SR includes:

The first transmission parameter of the SR is obtained according to the coverage enhancement level of the SR. For example, before acquiring the first transmission parameter of the SR according to the coverage enhancement level of the SR, the coverage enhancement level of the different SR and the different values of the first transmission parameter of the SR may be paired with each other, so that the coverage enhancement level of any SR is The first transmission parameter of the unique SR corresponds to a value.

The first transmission parameter may also be preset or pre-configured.

Step 301: The base station determines, according to the first transmission parameter of the SR, a time interval for receiving the SR, and combines and receives the SR in the determined time interval.

In this step, the time interval determined according to the first transmission parameter is a time interval that is continuous or discontinuous.

In this step, the determining, by the base station, the received SR time interval according to the first transmission parameter of the SR includes:

The base station divides all time intervals in the scheduling period P _SR in the first transmission parameter into P _SR /N _SR time interval blocks; wherein each time interval block includes N _SR time-continuous time intervals; The offset in the first transmission parameter determines that the time interval of receiving the SR is one of P _SR /N _SR time interval blocks; wherein, P _SR is a scheduling period in the first transmission parameter, and N _SR is the first transmission parameter The number of repetitions in .

The base station determines, according to the offset in the first transmission parameter, that the time interval of receiving the SR is one of P _SR /N _SR time interval blocks, including:

The base station determines the first time interval according to formula (1), and determines that the time interval for receiving the SR is the time continuous N _SR time intervals from the first time interval.

In the method for determining the time interval, by dividing all time intervals in the scheduling period P _SR into P _SR /N _SR time interval blocks, each time interval block includes N _SR time-continuous time intervals, such that , dependent on the value assigned O _SR, the base station selects a reception merge all the SR block of time interval; assign different for different UE O _SR value, the UE can be different repeatedly transmitted using different time intervals to block SR, and the base station may also block and receive the SRs sent by different UEs in different time intervals. This method has the benefit of lower implementation complexity and smaller transmission delay.

Or the base station divides all time intervals in the scheduling period P _SR or K _SR N _SR in the first transmission parameter into K _SR or P _SR /N _SR time interval blocks; wherein each time interval block includes N _SR time-discontinuous time interval, and the time interval between two adjacent time intervals is K _SR or P _SR /N _SR ; the base station determines that the time interval of receiving the SR is K according to the offset in the first transmission parameter _SR or P _SR /N _SR One of the time interval blocks.

The base station determines, according to the offset in the first transmission parameter, that the time interval of receiving the SR is one of K _SR or P _SR /N _SR time interval blocks, and the base station determines the first according to formula (2) or (3). For each time interval, it is determined that the time interval in which the SR is received is the N _SR time intervals in which the time from the first time interval is discontinuous.

In the method for determining the time interval, all the time intervals in each scheduling period P _SR are divided into P _SR /N _SR or K _SR time interval blocks, and each time interval block includes N _SR uniform distributions and time discrete time intervals, and two adjacent time interval for time intervals P _{_SR} / N _SR or _SR K, dependent on the value assigned O _SR, the base station selects a reception merge all the SR block of time interval; different by different _SR values allocated to the UE O, the UE may use different time intervals different block repeat transmission SR, the base station receiver can also be combined in different SR sent by the UE in different time intervals block. The method provides sufficient time diversity gain, reduces the number of repetitions required in the scheduling period, and reduces the corresponding control overhead; when the HARQ-ACK repeated transmission takes up a continuous time interval, due to the SR repetition at this time The transmission is occupied by a discontinuous time interval, so the SR and HARQ-ACK may not share the same number of repeated transmissions.

Or the base station divides all time intervals in the scheduling period P _SR in the first transmission parameter into P _SR /(K _SR N _SR ) scheduling areas; wherein each scheduling area includes K _SR N _SR time continuous time Interval; the base station divides all time intervals in each scheduling area into K _SR time interval blocks; wherein each time interval block includes N _SR time discontinuous time intervals, and adjacent two time intervals The time interval between the two is K _SR ; the base station determines, according to the offset in the first transmission parameter, that the time interval for receiving the SR is one of P _SR /N _SR time interval blocks.

The base station determines the first time interval according to formula (4), and determines that the time interval for receiving the SR is N _SR time intervals that are discontinuous from the first time interval.

The time interval between two adjacent time intervals may be K _SR .

In the method for determining the time interval, all the time intervals in each scheduling period P _SR are divided into P _SR /(K _SR N _SR ) scheduling areas, and each scheduling area includes K _SR N _SR time intervals, All time intervals in each scheduling area are divided into K _SR time interval blocks, and each time interval block includes N _SR uniformly distributed time discontinuous time intervals, and the interval between adjacent two time intervals is K. _SR , depending on the assigned O _{SR, 1} and O _{SR, 2} values, the base station selects one of all time interval partitions to receive the SR; by assigning different O _{SRs, 1} and O _{SR, 2} values for different UEs The different UEs may repeatedly transmit the SRs by using different time interval blocks in the same or different scheduling areas, and the base station may also block and receive the SRs sent by different UEs in different time intervals in the same or different scheduling areas.

The method has a relatively small time diversity gain, but reduces the transmission delay of the SR to a certain extent, thereby achieving a balance between control overhead and delay; when the HARQ-ACK repeated transmission takes up a continuous time interval, Since the SR repeated transmission at this time is a discontinuous time interval, the SR and HARQ-ACK may not share the same number of repeated transmissions.

It should be emphasized that, in the repeated transmission modes of all the foregoing SRs, the N _SR time intervals of the receiving SR periodically occur at intervals of the scheduling period P _SR .

Alternatively, the base station divides all time intervals into K _SR time interval packets; wherein each time interval packet includes a time interval in which the time is not continuous, and the time interval between two adjacent time intervals is K _SR ; The offset in a transmission parameter determines the time interval in which the SR is received as one of the K _SR packets.

The base station determines, according to the offset in the first transmission parameter, that the time interval of receiving the SR is one of K _SR packets, and the base station determines, according to formula (5), a time interval for receiving the SR.

The time interval between two adjacent time intervals may be K _SR .

In the method for determining the time interval, all time intervals are divided into K _SR packets, each packet includes N _SR uniformly distributed time discontinuities, and the time interval between two adjacent time intervals is K _SR , depending on the assigned value of O _SR , the base station selects one of all time interval packets to receive the SR in combination; by assigning different _OSR values to different UEs, different UEs may use different time interval packet repetition. The SR is sent, and the base station may also combine and receive the SRs sent by different UEs in different time intervals.

In this step, when the base station determines, according to the offset in the first transmission parameter, that the time interval of receiving the SR is one of K _SR packets, combining the received SRs in the determined time interval includes: in the determined time interval Follow the sliding window to merge and receive the SR.

Since the base station cannot know the time interval position of the first transmission SR, it is necessary to sequentially attempt to merge and receive the SR according to the sliding window. The sliding window includes an integer number of time intervals, that is, the sliding window is also in units of time intervals; the sliding window may also be determined according to the coverage enhancement level of the SR, for example, the sliding window and the coverage enhancement level of the SR may be set in the base station in advance. The correspondence between the two is determined.

The combining and receiving the SR according to the sliding window in the determined time interval includes:

Try to merge and receive the following SR time intervals in sequence:

{TIN ₀ , TIN ₁ , TIN ₂ , ..., TIN _W-1 }, {TIN ₁ , TIN ₂ , TIN ₃ , ..., TIN _W },

{TIN ₂ , TIN ₃ , TIN ₄ , ..., TIN _W+1 },

{TIN ₃ , TIN ₄ , TIN ₅ , ..., TIN _W+2 },......

Where W represents a sliding window, and TIN _i (i = 0, 1, 2, ...) represents a set of numbers that can be used to combine the time intervals of the received SR.

For example, imagine that TIN _i can be expressed as:

1m, 2m, 3m, 4m, 5m, 6m, 7m, 8m, 9m, ...,

At this time, the offset O _SR is equal to 0, and the repeated transmission interval K _SR is equal to m; the determined sliding window W is assumed to be 5 time intervals, in which case the base station sequentially attempts to combine and receive the potential SRs in the following 5 time intervals. Transfer until the SR is decoded correctly:

{1m, 2m, 3m, 4m, 5m}, {2m, 3m, 4m, 5m, 6m},

{3m, 4m, 5m, 6m, 7m}, {4m, 5m, 6m, 7m, 8m}, ....

The base station may preset one or more sliding windows of different sizes, and the base station respectively performs trial reception by using a preset sliding window (for example, in descending order).

In this step, combining the received SRs in the determined time interval includes:
