Description

Configuration method and device

The present application is filed and claimed as priority based on chinese patent application No. 201710184877.4 filed on 2017, 03-24, whose entire content is incorporated herein by reference.

Technical Field

The present invention relates to wireless network transmission technologies in the field of communications, and in particular, to a configuration method and apparatus.

Background

Machine Type Communication (MTC) user terminals (user equipment, UE for short) (hereinafter, MTC UE for short), also called Machine to Machine (M2M for short) user terminals, are the main application forms of the internet of things at the present stage, and low power consumption and low cost are important guarantees that MTC user terminals can be applied in a large scale.

At present, the main alternative methods for reducing the cost of the MTC user terminal include reducing the terminal receiving antenna, reducing the terminal baseband processing bandwidth, reducing the peak rate supported by the terminal, and adopting a half-duplex mode. However, the cost of the MTC ue is reduced by adopting the foregoing method at the expense of the performance degradation of the MTC ue. In this way, some measures need to be taken for the MTC ue to improve the performance so as to meet the performance requirement of the common terminal, for example, data or signals are transmitted through a single subcarrier, and the power is concentrated on the single subcarrier to ensure the receiving performance of the data or signals.

However, when a plurality of MTC ues use the same subcarrier to transmit data or signals, the transmitted power on the subcarrier is high, which may cause the transmitted data or signals of the plurality of MTC ues to interfere with each other, and further cause the receiving end to fail to receive the data or signals. Or, when the MTC user terminals in multiple cells use the same subcarrier to transmit data or signals, the MTC user terminals in multiple cells may also interfere with each other due to the higher transmission power on the subcarrier, and thus the receiving end may not receive the data or signals successfully. In addition, there is no complete solution in the industry for supporting the implementation of MTC ues to transmit and receive data or signals in a large cell (e.g., a cell radius exceeding 100 km).

It can be understood that, if at least one symbol set of the above four different structures is configured in this way, the time domain length of the symbol set occupies an integer number of milliseconds, and alignment at the millisecond level can be achieved, so as to avoid interference to subsequent other data or channels during transmission; moreover, the time domain length of the symbol set can be made to be less than 4ms, so that the situation that the channel time domain characteristic changes when the symbol set is too long can not occur, and further the influence on the receiving detection performance of the signal is small when the signal is detected at a receiving end; finally, the length of the symbol set is not too short, for example, not less than 2ms, which avoids the number N of symbols being too small, and further avoids the situation that the cross-correlation of N long sequences is not good, and also has little influence on the receiving detection performance of the signal when detecting at the receiving end.

the subcarrier interval is 3750Hz, the length of the cyclic prefix is 24576 Ts, the length of N symbols is 8192 Ts, and the number of the symbols N is any one of 2-3.

It can be understood that if at least one of the four symbol sets with different structures is configured in this way, the time domain length of each symbol set can be smaller than 4ms, and the situation that the channel time domain characteristics are changed due to too long symbol sets does not occur, so that the influence on the receiving detection performance of signals when the receiving end detects the signals is small; the length of the symbol set is not too short, for example, not less than 2ms, which avoids the number N of symbols being too small, and further avoids the situation that the cross-correlation of N long sequences is not good, and also has little influence on the receiving detection performance of the signal when detecting at the receiving end.

It can be understood that, if at least one symbol set of the above four different structures is configured in this way, the time domain length of the symbol set occupies an integer number of milliseconds, and alignment at the millisecond level can be achieved, so as to avoid interference to subsequent other data or channels during transmission; moreover, the time domain length of the symbol set can be made to be less than 4ms, so that the situation that the channel time domain characteristic changes when the symbol set is too long can not occur, and further the influence on the receiving detection performance of the signal is small when the signal is detected at a receiving end; finally, the length of the symbol set is not too short, for example, not less than 1ms, which avoids the number N of symbols being too small, and further avoids the situation that the cross-correlation of N long sequences is not good, and also has little influence on the receiving detection performance of the signal when detecting at the receiving end.

It should be noted that, after obtaining the configuration information of the at least one symbol set and the configuration of the first resource, the at least one symbol set may be configured on the first resource according to the configuration information.

That is to say, the length of the cyclic prefix may be a preset configuration value M, or one configuration value may be selected for configuration according to the index information corresponding to the preset configuration value M.

It should be noted that, in the embodiment of the present invention, the first node may select an appropriate cyclic prefix length according to the supported cell radius. Thus, the normal transmission of signals can be performed regardless of the size of the supported cell.

It should be noted that, the length of 8192 time-domain sampling intervals is equal to the time-domain length of the OFDM symbol of the 3.75kHz subcarrier interval; the 2048 time domain sampling interval lengths are equal to the time domain length of the 15kHz subcarrier interval OFDM symbols; the 20480 time domain sample interval lengths are equivalent to 10 times the time domain length of the 15kHz subcarrier interval OFDM symbols; the 20480 time domain sample interval lengths are equivalent to 2.5 times the time domain length of the 3.75kHz subcarrier spacing OFDM symbols; the 24576 time-domain sample interval length is equivalent to 3 times the time-domain length of the 3.75kHz subcarrier spacing OFDM symbol.

Preferably, W is 6 or 12, and W may be selected according to practical applications, and embodiments of the present invention are not limited.

For example, in eight symbol sets (H symbol sets) adjacent to each other in the time domain in at least one symbol set (e.g., indexes of the symbol sets are defined as 0 to 7), resources occupied by the symbol sets 0 to 3 are included in a first time-frequency resource block, and resources occupied by the symbol sets 4 to 7 are included in a second time-frequency resource block; the first time-frequency resource block is composed of A first time-frequency resource subblocks, wherein A is an integer greater than or equal to 1, the time domain length of each first time-frequency resource subblock is the time domain length corresponding to 4 symbol sets, and the frequency domain length of each first time-frequency resource subblock is 12 subcarriers; the second time frequency resource block is composed of A second time frequency resource sub-blocks, wherein A is an integer larger than or equal to 1, the time domain length of the second time frequency resource sub-blocks is the time domain length corresponding to 4 symbol sets, and the frequency domain length of the second time frequency resource sub-blocks is 12 subcarriers; the first time frequency resource block and the second time frequency resource block are separated by T time units in the time domain, and T is more than or equal to 0.

More specifically, the first node configures the first H/2 symbol sets in the same first time-frequency resource sub-block; and the first node configures the latter H/2 symbol sets in the same second time-frequency resource sub-block.

Optionally, the index of the first time-frequency resource sub-block configured by the first H/2 symbol sets is the same as the index of the second time-frequency resource sub-block configured by the second H/2 symbol sets. For example, the first time-frequency resource subblock index configured from the symbol set 0 to the symbol set 3 is the same as the second time-frequency resource subblock index configured from the symbol set 4 to the symbol set 7.

Optionally, a second condition is satisfied between an index k of the starting subcarrier of the first time-frequency resource subblock and an index q of the starting subcarrier of the second time-frequency resource subblock; the second condition is formula (8):

When q ═ k + D is satisfied between the starting subcarrier index k of the first time-frequency resource subblock and the starting subcarrier index q of the second time-frequency resource subblock, where D is an integer, a first predetermined rule is as shown in fig. 3, as follows:

Wherein, the frequency domain interval is D subcarriers.

For example, when H is 8 and W is 6, take a first time-frequency resource sub-block with an index of 0 in a first time-frequency resource block and a second time-frequency resource sub-block with an index of 0 in a second time-frequency resource block as an example, where the time domain interval is T time units. When q ═ k + D is satisfied between the starting subcarrier index k of the first time-frequency resource subblock and the starting subcarrier index q of the second time-frequency resource subblock, where D is an integer, a first predetermined rule is as shown in fig. 4, as follows:

Optionally, a subcarrier interval in one symbol set of the at least one symbol set is 1250Hz, a length of a cyclic prefix is 0.8ms, and a length of a symbol in the one symbol set is 0.8ms, where ms is millisecond, and 0.8ms is 1/(1250Hz) ═ 0.8 ms.
