technical field

Embodiments of the present invention relate to the field of communication technologies, and in particular, to a signal sending method and sending device.

Background technique

In an unlicensed frequency band, when a transmitting device sends a signal to a receiving device, it needs to meet the regulation requirements (regulation) of the occupied channel bandwidth (OCB). Generally, in order to meet the OCB regulations, the transmitting device may repeatedly transmit the same signal on some resources.

1. OCB's regulatory requirements

Generally, in the unlicensed frequency band, for the 60GHz frequency band (that is, the frequency band with the center frequency of 60GHz), the transmitting device needs to occupy at least 70% of the bandwidth of the frequency band when sending signals; for the 5GHz frequency band (that is, the center frequency is 5GHz). frequency band), the sending device needs to occupy at least 80% of the bandwidth of the frequency band when sending signals. For example, taking the 5GHz frequency band as an example, assuming that the 5GHz frequency band is divided according to the bandwidth of 20MHz, the sending device needs to occupy at least 80% of the 20MHz, that is, 16MHz, when sending a signal.

It should be noted that the frequency band can also be divided according to the bandwidth of 20MHz or the bandwidth of 10MHz. In the embodiment of the present invention, the signal sending method provided by the embodiment of the present invention can be used for different division rules.

2. Physical Resource Block (Resource Block, RB) and Resource Element (Resource Element, RE)

The RE is the smallest resource unit, which is an Orthogonal Frequency Division Multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbol in the time domain, and a subcarrier in the frequency domain. RB is a resource unit allocated by traffic channel resources, which is a time slot in the time domain and 12 subcarriers in the frequency domain.

3. Interlace structure

Generally, on an unlicensed frequency band, the sending device may use RBs with an interlace structure for uplink transmission. If the frequency band is divided according to a bandwidth of 20 MHz, each interlace may contain 10 or 11 RBs. For the subcarrier spacing of 15KHz, the 20MHz bandwidth contains at most 106 RBs, and the RB spacing corresponding to every two interlaces is 10 RBs. For the 30KHz subcarrier spacing, the 20MHz bandwidth contains at most 51 RBs, and the RB spacing corresponding to each interval is 5 RBs.

For example, for the subcarrier interval of 30KH, if each interlace includes 10 RBs, and the interval between the RBs corresponding to every two interlaces is 5 RBs, if the interlace structure is adopted, then RB#3, RB# 8. Signals are transmitted on RB#13, RB#18, RB#23, RB#28, RB#33, RB#38, RB#43, and RB#48.

It should be noted that the frequency band is divided according to the bandwidth of 10MHz, and the interlace structure may also refer to the above-mentioned division. The number of RBs included in the interlace may be the same as the number of RBs corresponding to the bandwidth division of 20MHz, or may be different, which is not specifically limited in this embodiment of the present invention.

Since the phases of the signals sent on at least two frequency-domain resource sets in the M frequency-domain resource sets are different, the amplitudes of the M signals at the same time are not exactly the same. For example, the amplitudes of some signals are positive, and some The amplitude of the signal is negative, the amplitude of some signals is the maximum value, and the amplitude of some signals is the minimum value, etc. Therefore, the probability that the amplitude of the signal superimposed on the same time domain resource is too large can be reduced.

Since the phases of the signals sent on at least two frequency-domain resource sets in the M frequency-domain resource sets are different, the amplitudes of the M signals at the same time are not exactly the same. For example, the amplitudes of some signals are positive, and some The amplitude of the signal is negative, the amplitude of some signals is the maximum value, and the amplitude of some signals is the minimum value, etc. Therefore, the probability that the amplitude of the signal superimposed on the same time domain resource is too large can be reduced.

Optionally, in this embodiment of the present invention, the signals sent on the P frequency domain resource sets in the M frequency domain resource sets are signals whose phases are adjusted according to the P symbol factors, where P is a positive integer less than or equal to M. Among them, a symbol factor is used to adjust the phase of a signal sent on a frequency domain resource set.

Exemplarily, when P=1, a symbol factor is used to adjust the phase of a signal sent on a corresponding set of frequency-domain resources; when P is greater than 1, P symbol factors are used to adjust the corresponding P frequencies respectively. The phases of the P signals sent on the domain resource set, and one frequency domain resource set corresponds to one symbol factor.

For example, if P=3, the three frequency domain resource sets are: frequency domain resource set 1, frequency domain resource set 2 and frequency domain resource set 3; the three symbol factors are: symbol factor 1, symbol factor 2 and symbol factor 3 respectively . Then the transmitting device can use the symbol factor 1 to adjust the phase of the signal sent on the frequency domain resource set 1, use the symbol factor 2 to adjust the phase of the signal sent on the frequency domain resource set 2, and use the symbol factor 3 to adjust the signal sent on the frequency domain resource set 3. phase.

It should be noted that, in this embodiment of the present invention, the modulus value of the sign factor may be 1.

Exemplarily, the sign factor in this embodiment of the present invention may be a phase rotation sign factor, and the phase rotation sign factor is used to perform phase rotation on the symbol.

Optionally, in this embodiment of the present invention, the values of the P symbol factors may be partially different or completely different.

It can be understood that the phases of the signals after the phase adjustment using the sign factors of the same value are the same, and the phases of the signals after the phase adjustment using the sign factors of different values are different.

Optionally, in this embodiment of the present invention, in the case of P=M, at least two of the P symbol factors are different.

It can be understood that in the case of P=M, if the sign factors are exactly the same, it means that the phase is not adjusted. Therefore, in the case of P=M, at least two sign factors among the M sign factors used by the transmitting device different, it is guaranteed that at least one signal has a different phase than the other signals.

Optionally, in this embodiment of the present invention, the above-mentioned P symbol factors are predefined, selected by a sending device, or indicated by a network device.

Specifically, the P symbol factors in the sending device may be specified by the communication protocol, or may be predefined by the manufacturer of each sending device.

It should be noted that the sending device can acquire multiple sets of symbol factors, and the sending device can select one set of symbol factors from the multiple sets of symbol factors as required. For example, multiple groups of symbol factors may be predefined for the sending device according to different channels or indicated by the network device, and the sending device may select different symbol factors according to different channels used.

Optionally, in the embodiment of the present invention, the above-mentioned P symbol factors are obtained by the network device through system information, Radio Resource Control (Radio Resource Control, RRC) signaling, and a Media Access Control-Control Element (Media Access Control-Control Element, MAC-CE) or downlink control information (Downlink Control Information, DCI) indicated.

Optionally, in the embodiment of the present invention, the above-mentioned P frequency domain resource sets are any one of the following: P physical resource blocks RB, and P RB sets. Wherein, each RB set in the above-mentioned P RB sets includes K RBs, and K is a positive integer.

It can be understood that when the P frequency domain resource sets are P RBs, the sending device can send P phase-adjusted signals on the P physical resource blocks, and divide the P physical resource blocks in the M frequency domain resource sets. Unphased (M-P) signals are sent on resource blocks.

Exemplarily, assuming that the M frequency domain resource sets are 10 RBs, for example, they are respectively: RB#3, RB#8, RB#13, RB#18, RB#23, RB#28, RB#33, RB #38, RB#43, RB#48. When P=5, the sending device can adjust the phase of the signal sent on 5 RBs, the sending device can adjust the phase of the signal sent on RB#3 according to the symbol factor 1, and the signal sent on RB#13 according to the symbol factor 2 , adjust the phase of the signal sent on RB#23 according to the symbol factor 3, adjust the phase of the signal sent on RB#33 according to the symbol factor 4, and adjust the phase of the signal sent on RB#43 according to the symbol factor 5; other The signal on RB may not be phase adjusted.

It should be noted that, if the first RB corresponds to the first symbol factor, the transmitting device uses the first symbol factor corresponding to the first RB to adjust the phases of the signals in all REs in the first RB.

It can be understood that when the P frequency domain resource sets are P RB sets, the sending device may send P phase-adjusted signals on the P frequency domain resource sets.

Exemplarily, it is assumed that the M frequency domain resource sets are 4 RB sets (also referred to as 4 clusters of RBs), for example, RB set 1 includes RB#0 to RB#11, and RB set 2 includes RB#12 to RB#23 , RB set 3 includes RB#24 to RB#35, and RB set 4 includes RB#36 to RB#47. When P=M=4, the sending device can adjust the phases of the signals sent on the 4 RB sets, the sending device can adjust the phases of the signals sent on RB#0 to RB#11 according to the symbol factor A, and the sending device can adjust the phases of the signals sent on RB#0 to RB#11 according to the symbol factor A. The factor B adjusts the phase of the signals sent on RB#12 to RB#23, the sending device can adjust the phase of the signals sent on RB#24 to RB#35 according to the symbol factor C, and the sending device can adjust the RB#36 according to the symbol factor D To the phase of the signal sent on RB#47.

It should be noted that if the first RB set corresponds to the second symbol factor, the transmitting device uses the second symbol factor corresponding to the first RB set to adjust the phases of the signals in all REs in the 12 RBs in the first RB set .

For example, taking RB set 1 as an example, the transmitting device uses the symbol factor A to adjust the phases of the signals in RB#0 to RB#11 in the RB set 1. Specifically, the transmitting device uses the symbol factor A to adjust the phases of RB#0 to RB#11 The phase of the signal in the 144 REs.

Optionally, in this embodiment of the present invention, the above K RBs may be consecutive RBs.

It should be noted that multiple RBs in each RB set are consecutive, for example, RB set A includes RB#1, RB#2, and RB#3; RB set B includes RB#6, RB#7, and RB# 8.

Optionally, in this embodiment of the present invention, the above-mentioned P RB sets may be RB sets with consecutive RBs.

Exemplarily, it is assumed that P=4, that is, 4 RB sets, namely RB set 1 (or the first cluster of RBs), RB set 2 (or the second cluster of RBs), RB set 3 (or the third cluster of RBs), and RB set 4 (or 4th cluster of RBs). Each RB set (or each cluster of RBs) includes 12 consecutive RBs. The RB set 1 includes RB#0 to RB#11, the RB set 2 includes RB#12 to RB#23, the RB set 3 includes RB#24 to RB#35, and the RB set 4 includes RB#36 to RB47.

For example, when sending a signal on the PRACH, the sending device can use a set of RBs with continuous RBs to repeatedly send a signal carrying the same information. For example, when sending a preamble sequence, the above four RB clusters can be used to repeatedly send the preamble sequence.

Optionally, in this embodiment of the present invention, the above-mentioned P RB sets may be RB sets with discontinuous RBs.

Exemplarily, it is assumed that P=4, that is, there are 4 RB sets, which are RB set a, RB set b, RB set c, and RB set d, respectively. Each RB set includes two consecutive RB sets. The RB set a includes RB#0 and RB#1, the RB set b includes RB#7 and RB#8, the RB set c includes RB#14 and RB#15, and the RB set d includes RB#21 and RB#16.

For example, when the transmitting device transmits a signal on the PSFCH or PSSCH, it may use a discontinuous RB set to repeatedly transmit the signal. Taking 1 RB as the granularity (ie, K=1), the sending device can repeatedly send the signal carrying the same information on 4 discontinuous RBs. For example, signal 1 is repeatedly transmitted on RB#3, RB#8, RB#13, and RB#23, and the signals on the four RBs are signal 1 whose phases are adjusted. Of course, the signal carrying the same information can also be repeatedly sent with 2 RBs (ie, K=2) or more RBs as the granularity. For example, signal 1 with phase 1 is sent on RB#0 and RB#1, signal 1 with phase 2 is sent on RB#7 and RB#8, and signal 1 with phase 2 is sent on RB#14 and RB#15. Signal 1 of phase 3, signal 1 of phase 4 is transmitted on RB#21 and RB#16.

It should be noted that when one RB is used as the granularity, the transmission may be repeated 2 times, 4 times, 5 times, 8 times or 10 times at different frequency positions. In the case of taking 2 RBs as the granularity, the transmission can be repeated 2 times, 4 times or 5 times at different frequency positions.

It should be noted that the granularity of the RB set may be determined according to the data amount of the signal, and may be determined as required during specific transmission, which is not specifically limited in this embodiment of the present invention.

计算得到，

calculated,

is an integer, and N is a positive integer.

Specifically, assuming that the original signal is x(n) and the sign factor is d(m), the phase-adjusted signal can be calculated according to y(n)=d(m)*x(n). Wherein, x(n) may represent the original signal on RE#n, and y(n) may represent the signal on RE#n after adjusting the phase of the original signal. d(m) may represent the symbol factor m used corresponding to the RE#n.
