In step 201 and step 202, the network equipment can refer to eNB, or the equipment with eNB functions, the application
Embodiment is not limited this.
M continuous running time-frequency resource subelements can be included in the embodiment of the present application, in a running time-frequency resource unit, each
N number of basic time domain unit can be included in running time-frequency resource subelement, M, N are natural number.M and N value can be according to actual feelings
Condition determines, does not limit herein.Accordingly, the first running time-frequency resource subelement and second that a running time-frequency resource unit includes
The quantity of running time-frequency resource subelement can determine that the embodiment of the present application is not limited this according to actual conditions.
In the embodiment of the present application, running time-frequency resource unit can be the money with wireless frame structure in fdd mode or tdd mode
Source unit, or be the resource unit with wireless frame structure in similar fdd mode or tdd mode.Accordingly, a time-frequency money
Source subelement can be the resource unit of a subframe structure in the radio frames with fdd mode or tdd mode.Each time-frequency money
Basic time domain unit included in the subelement of source can refer to OFDM symbol, SC-FDMA (Single carrier
Frequency Division MultipleAccess, single-carrier frequency division multiple access) symbol such as symbol, the embodiment of the present application is to this
Do not limit.
In the embodiment of the present application, the up-downgoing attribute of each basic time domain unit indicates that the basic time domain unit is up
Time domain unit (time domain unit i.e. for uplink) or descending time domain unit (time domain unit i.e. for downlink transfer).
The up-downgoing attribute of each basic time domain unit is pre-configured in first running time-frequency resource subelement, refers to the first running time-frequency resource
The up-downgoing attribute of each basic time domain unit is good or appointed by the network equipment and terminal by protocol conventions in unit
, it will not change.For example, in tdd mode, in a radio frames subframe numbers be respectively #0, #1, #5 subframe without
By being descending sub frame under which kind of ratio of uplink subframe to downlink subframe pattern, no matter subframe numbers are #2 subframe in which kind of ascending-descending subframes
It is sub-frame of uplink under proportioning pattern, the up-downgoing attribute of these subframes is exactly pre-configured.In the embodiment of the present application, when basic
When the up-downgoing attribute of domain unit is pre-configured, pre-configured implication can be identical with the implication of above example.
Again for example, a first time-domain resource subelement includes 14 basic time domain units, and wherein index value is
0th, the up-downgoing attribute of basic time domain unit corresponding to 1,2,3,4,5 it is prewired be set to it is up；Index value is basic corresponding to 6 to 13
The up-downgoing attribute of time domain unit is prewired be set to it is descending.Under above-mentioned configuration, under any circumstance, index value 0,1,2,3,4,5
Corresponding basic time domain unit is all only used for carrying out up transmission, index value be basic time domain unit corresponding to 6 to 13 all only
It can be used to carry out descending transmission.
It should be noted that the index value of time domain unit is the basic time domain unit residing for the basic time domain unit substantially
Running time-frequency resource subelement in Position Number, can indicate that basic time domain unit be located at residing for the basic time domain unit when
Position in frequency resource subelement.Meanwhile in the embodiment of the present application, the rope of each basic time domain unit in running time-frequency resource subelement
Draw value be over time successively it is gradually incremental, i.e., in running time-frequency resource subelement before basic time domain unit index value
More than the index value of the basic time domain unit behind in running time-frequency resource subelement.For example, in a running time-frequency resource subelement
Including 7 basic time domain units, then the basic time domain unit that index value is 0 represents that the basic time domain unit is running time-frequency resource
First basic time domain unit in unit, the basic time domain unit that index value is 3 represent that the basic time domain unit is the time-frequency
The 4th basic time domain unit in resource subelement.
Accordingly, a up-downgoing attribute is comprised at least in the embodiment of the present application, in the second running time-frequency resource subelement to treat
The basic time domain unit of configuration, except up-downgoing attribute is basic time domain unit to be configured in the second running time-frequency resource subelement,
The up-downgoing attribute of other basic time domain units can be pre-configured.Up-downgoing attribute is basic time domain unit to be configured
Refer to that the up-downgoing attribute of the basic time domain unit is variable, can flexibly be changed according to actual conditions, therefore up-downgoing category
Property for basic time domain unit to be configured before transmitting, it is necessary to the network equipment determine the basic time domain unit be it is up or under
OK, can specifically be determined by the network equipment according to actual conditions.For example, in tdd mode, subframe numbers in a radio frames
Respectively #3, #4, #6, #7, #8, #9 subframe can be sub-frame of uplink, or descending sub frame, with specific reference to not being same as above
Descending sub frame proportioning pattern determines that the up-downgoing attribute of these subframes is exactly to be to be configured.In the embodiment of the present application, when basic
When the up-downgoing attribute of domain unit is to be configured, implication to be configured can be identical with the implication of above example.
Again for example, a second time-domain resource subelement includes 14 basic time domain units, and wherein index value is
0th, the up-downgoing attribute of basic time domain unit corresponding to 1,2,3 is pre-configured；The up-downgoing attribute of remaining basic time domain unit
To be to be configured.The network equipment is before the second time domain subelement is sent, it is thus necessary to determine that the base in the second time domain subelement
Index value is that basic time domain unit is up or descending corresponding to 4 to 13 in this time domain unit.
It should be noted that in the embodiment of the present application, the network equipment can by up-downgoing attribute for it is to be configured basic when
The result of the uplink-downlink configuration of domain unit is sent to terminal by signaling.For example, DCI (Downlink Control can be passed through
Information, Downlink Control Information) or RRC (Radio Resource Control, wireless heterogeneous networks) signaling be sent to
Terminal.
In the embodiment of the present application, in a kind of possible implementation, the network equipment only sends the first synchronizing signal, and this first
The institute that synchronizing signal can comprise at least PSS and SSS is functional, and the first synchronizing signal that now network equipment is sent can be used
Mark in the group of physical area, the 5mstiming (timing) of physical area, physical area group mark, circulation are determined in instruction terminal
Prefix configuration (being normal cyclic prefix or the cyclic prefix of extension), system-frame timing are (i.e. in system-frame where subframe 0
Position).Certainly, it is example above, the first synchronizing signal also can indicate that terminal determines the other information of cell, herein not
Repeat again.
In alternatively possible implementation, the network equipment needs to send the first synchronizing signal and the second synchronizing signal.
Now, first synchronizing signal can including at least PSS institute it is functional；Second synchronizing signal can comprise at least SSS institute
It is functional.The first synchronizing signal that i.e. network equipment is sent can serve to indicate that terminal determines mark, physics in the group of physical area
The 5ms timing (timing) of cell；The second synchronizing signal that the network equipment is sent can serve to indicate that terminal determines physical area
Group mark, cyclic prefix configuration (being normal cyclic prefix or the cyclic prefix of extension), system-frame timing (i.e. system-frames
Position where middle subframe 0).Certainly, it is above example, the first synchronizing signal and the second synchronizing signal also can indicate that end
End determines the other information of cell, will not be repeated here.
In the implementation, the network equipment can be in base corresponding to the 3rd index value on the first running time-frequency resource subelement
The second synchronizing signal is sent on this time domain unit；And the network equipment can be at least one second running time-frequency resource subelement
The 4th index value corresponding to send the second synchronizing signal on basic time domain unit；Wherein, the 3rd index value and the 4th index value
It is different.Wherein, sent in each first running time-frequency resource subelement corresponding to the basic time domain unit of second synchronizing signal
Three index values are identical, corresponding to the basic time domain unit that second synchronizing signal is sent in each second running time-frequency resource subelement
4th index value is identical.
In the embodiment of the present application, when the network equipment is sent first used in the first synchronizing signal and the second synchronizing signal
The quantity of frequency resource subelement and the second running time-frequency resource subelement can be made an appointment by agreement, by sender and can also be connect
Debit is made an appointment, and the embodiment of the present application is not limited this.
In a kind of possible implementation, all first running time-frequency resource subelements of the network equipment in running time-frequency resource unit
It is synchronous that second is sent in the first synchronizing signal of upper transmission, at least one second running time-frequency resource subelement in running time-frequency resource unit
Signal.
Certainly, it is example above, the network equipment sends used in the first synchronizing signal and the second synchronizing signal the
The quantity of one running time-frequency resource subelement and the second running time-frequency resource subelement can also have other forms, no longer illustrate one by one herein
Explanation.
It should be noted that although have been described for that the network equipment sends the first synchronizing signal and the second synchronizing signal and made
The quantity of first running time-frequency resource subelement and the second running time-frequency resource subelement, and the first synchronizing signal and second same
The function of signal is walked, but those skilled in the art can carry out various changes and modification without departing from this to the embodiment of the present application
Apply for the scope of embodiment.So, in subsequent protocol evolution, if belonging to this to these modifications and variations of the embodiment of the present application
Within the scope of applying for claim, then the embodiment of the present application is also intended to comprising including these changes and modification.
In step 201 and step 202, the network equipment sends the first synchronizing signal and on running time-frequency resource subelement
Position of the basic time domain unit of two synchronizing signals in running time-frequency resource subelement, can be determined according to actual conditions.
In the first possible implementation, first running time-frequency resource of the network equipment in the running time-frequency resource unit is single
The index value of the basic time domain unit of the first synchronizing signal is sent in member more than at least one in the running time-frequency resource unit
The index value of the basic time domain unit of the first synchronizing signal is sent on second running time-frequency resource subelement；Or the network equipment
The rope of the basic time domain unit of the second synchronizing signal is sent on the first running time-frequency resource subelement in the running time-frequency resource unit
Draw and send the second synchronizing signal at least one second running time-frequency resource subelement that value is more than in the running time-frequency resource unit
The index value of basic time domain unit, i.e., described first index value are more than second index value, or, the 3rd index value is big
In the 4th index value.
In the above method, when the first index value is more than the second index value, it is ensured that at least one first synchronous letter
Number do not sent on last basic time domain unit, so that the first running time-frequency resource subelement or the second time-frequency money
The up-downgoing attribute spirit of basic time domain unit in the subelement of source after the basic time domain unit for sending the first synchronizing signal
Work is variable, improves resource utilization ratio.Accordingly, when the 3rd index value is more than four index values, it is ensured that at least
One the second synchronizing signal is not sent on last basic time domain unit, so that the first running time-frequency resource subelement
Or the second basic time domain unit in running time-frequency resource subelement after the basic time domain unit for sending the second synchronizing signal
Up-downgoing attribute flexibility and changeability, improve resource utilization ratio.
For example, for the first running time-frequency resource subelement, basic time domain unit corresponding to the first index value for this first
The basic time domain unit of last in running time-frequency resource subelement, basic time domain unit corresponding to the 3rd index value is first time-frequency
The basic time domain unit of penultimate in resource subelement.For the second running time-frequency resource subelement, base corresponding to the 4th index value
This time domain unit is the 4th basic time domain unit in the running time-frequency resource subelement, basic time domain unit corresponding to the 3rd index value
For the 3rd basic time domain unit in the running time-frequency resource subelement.Specifically, as shown in figure 3, it is the embodiment of the present application offer
