The dual-mode antenna number of base station and terminal is very more in extensive antenna system, especially high band base station with UE is generated relatively narrow wave beam by extensive antenna and is sent signal in the way of beam scanning, UE can according to the configuration of base station with Period, aperiodic or semi-continuous mode send SRS.Specifically, the base station aperiodic can trigger the UE and send SRS, example Such as, the base station can trigger the signaling triggering UE transmission SRS by aperiodically sending aperiodic SRS to the UE. The base station can also trigger the UE periodicity sending SRS, for example, the base station can match to the UE sending cycle SRS Confidence breath periodically sends SRS to the base station according to the period SRS configuration information for triggering the UE.

Based on above-mentioned application scenarios, the present invention provides a kind of uplink beam indicating means, below with reference to specific embodiment Uplink beam indicating means of the invention is described in detail.UE of the present invention can be such as mobile phone, computer, household electrical appliances Equipment, tablet computer (Tablet Personal Computer), laptop computer (Laptop Computer), individual digital Assistant (personal digital assistant, abbreviation PDA), mobile Internet access device (Mobile Internet Device, ) or the terminal devices such as wearable device (Wearable Device) MID.The base station mentioned in the embodiment of the present invention can be Evolved base station (eNB, evolved Node B) or other base stations, it should be noted that in embodiments of the present invention not Limit the concrete type of base station.

It is a kind of flow diagram of uplink beam indicating means provided in an embodiment of the present invention, such as Fig. 1 referring to Fig. 1, Fig. 1 Shown, described method includes following steps:

Step 101, user terminal UE receive the uplink scheduling signaling that base station is sent, and carry in the uplink scheduling signaling Target identification information and detection reference signal SRS resource index, the target identification information are used to identify the n-th of the UE Send SRS, wherein the N is the integer more than or equal to 1.

Step 102, the UE determine that the SRS resource indexes corresponding SRS as target SRS when n-th sends SRS, and Determine that sending the uplink beam that the target SRS is used is target uplink beam, the target uplink beam is that the UE is used for Send the uplink beam of upstream data or uplink reference signals.

In the embodiment of the present invention, the UE receives the uplink scheduling signaling that base station is sent, and takes in the uplink scheduling signaling It being indexed with target identification information and SRS resource, the n-th that the target identification information is used to identify the UE sends SRS, Wherein, the N is the integer more than or equal to 1.For example, if the target identification information and the UE the 2nd time transmission Identification information when SRS is identical, then the target identification information indicates the 2nd transmission SRS of the UE.

The UE determines that the corresponding n-th of the target identification information sends SRS when institute according to the target identification information Stating SRS resource and indexing corresponding SRS is target SRS, then further determines that sending the uplink beam that the target SRS is used is Target uplink beam, the target uplink beam are the upgoing wave that the UE is used to send upstream data or uplink reference signals Beam.

The target SRS is the optimal SRS of the quality of reception that the base station is determined from the multiple SRS received, The base station further determines that the SRS transmission times where the target SRS, then determines the SRS hair where the target SRS Sending the corresponding identification information of number is the target identification information, and the target identification information is carried in the uplink scheduling It is sent in signaling to the UE.In this way, where the UE can determine the target SRS according to the target identification information SRS transmission times, i.e., the described UE can determine the target SRS for UE n-th transmission according to the target identification information SRS in a SRS, the UE may further determine that the SRS resource index corresponds to when the UE n-th sends SRS SRS be target SRS.

In the embodiment of the present invention, the bit number of identification information can be pre-set fixed value, can also be believed by high level Configuration is enabled, the embodiment of the present invention is not specifically limited in this embodiment.Assuming that the bit number of identification information is L, L is more than or equal to 1 Integer, then the value range of the identification information be 0~2^L-1。

The UE is previously stored at least one identification information and corresponding at least two SRS of each identification information The uplink beam information that is respectively adopted when sending, i.e., at least two SRS in the SRS sent each time are adopted respectively when sending Uplink beam information.The UE can first according to the target identification information determine send SRS number serial number (such as Determine that the target identification information corresponds to the SRS that the UE n-th is sent), then determine institute in the SRS of the n-th transmission Stating SRS resource and indexing corresponding SRS is target SRS, finally determines that sending the uplink beam that the target SRS is used is in target Traveling wave beam, the target uplink beam are the uplink beam that the UE is used to send upstream data or uplink reference signals.

It is understood that the UE determination is described at least as the SRS that identification information correspondence is sent at least twice Sending the last corresponding SRS of the index of SRS resource described in SRS that sends in SRS twice is target SRS.

In the embodiment, before the UE receives the uplink scheduling signaling that base station is sent, the UE is at least twice to described Base station sends SRS, and the uplink beam for saving identification information when sending SRS each time and using when sending SRS each time Information.The base station can determine whether that the optimal SRS of the quality of reception is target when receiving the SRS that the UE is sent at least twice SRS, the identification information that the n-th where then determining the target SRS sends SRS is the target identification information, and really SRS resource of the fixed target SRS in the SRS that n-th is sent indexes, and by the target identification information and the SRS Resource index carries in the uplink scheduling signaling, so that the UE is determined for sending upstream data or uplink with reference to letter Number uplink beam.The uplink beam information can be the number of uplink beam, be also possible to the configuration information of uplink beam, It can also be that other are not specifically limited in this embodiment for identifying the information of uplink beam, the embodiment of the present invention.

The UE sends SRS to the base station at least twice and can be in the aperiodic SRS for receiving the base station transmission It is sent under conditions of triggering signaling, specifically, the UE receives the aperiodic SRS triggering signaling that the base station is sent, then base Signaling, which is triggered, in the aperiodic SRS sends SRS to the base station.It should be noted that the UE often receives the base station The aperiodic SRS of one sent triggers signaling, and the UE sends a SRS to the base station.That is, in this kind of situation Under, the UE be that the UE receives that the base station sends to the premise that the base station sends SRS at least twice at least two Aperiodic SRS triggers signaling.

The UE sends SRS to the base station at least twice and is also possible in the period SRS for receiving the base station transmission It is sent under conditions of configuration information.Specifically, it is described when the UE receives the period SRS configuration information that the base station is sent UE periodically sends SRS to the base station according to the period SRS configuration information.

No matter the UE is periodically to send SRS to the base station, still aperiodically sends SRS to the base station, The UE can save identification information when sending SRS each time and send each time when sending SRS to the base station The uplink beam information used when SRS.Specifically, the case where SRS aperiodically being sent to the base station for the UE, institute It states in the aperiodic SRS triggering signaling of each of base station transmission and carries identification information, the UE is aperiodic based on one When SRS triggering signaling sends a SRS to the base station, the UE saves the mark carried in the aperiodic SRS triggering signaling of this Know information and this time sends the uplink beam information that SRS is used.The feelings of SRS are periodically sent to the base station for the UE Condition, the UE are identified number according to SRS of the preset rules to the secondary transmission when sending SRS to the base station each time, Then saving this time when sending SRS each time and sending the corresponding identifier number of SRS is the identification information that this time sends SRS, with And it saves this time and sends the uplink beam information that SRS is used.

In the embodiment, the UE receives at least two aperiodic SRS triggering signalings that the base station is sent, and is then based on At least two aperiodic SRS triggering signalings send SRS to the base station at least twice.Wherein, the aperiodic SRS touching of each Signaling is used to indicate the UE and sends a SRS to the base station.It is understood that the UE is at least twice to the base It stands to send after SRS is not limited at least two aperiodic SRS triggering signalings for being received entirely the base station transmission and execute, it can To be to send a SRS to the base station when often receiving an aperiodic SRS triggering signaling.

Assuming that the bit number of identification information is L, then the value range of identification information is 0~2^L- 1, the base station is to institute Stating when the aperiodic SRS of UE transmission each triggers signaling can choose 0~2^L- 1 one of value is used as the aperiodic SRS of this The identification information of signaling is triggered, the UE receives the aperiodic SRS triggering signaling of this, and triggers according to the aperiodic SRS of this Signaling sends a SRS to the base station, and the base station saves the identification information carried in the aperiodic SRS triggering signaling of this and is The identification information of this time transmission SRS.

For example, it is assumed that L=1 is carried when the base station sends first aperiodic SRS triggering signaling to the UE Identification information " 0 ", the UE are based on this first aperiodic SRS and trigger signaling to the transmission of base station the first time SRS, the UE Saving the first time, to send the identification information of SRS be " 0 ", and saves first time and send at least two SRS when sending SRS and distinguish The uplink beam information used.Identification information " 1 " is carried when base station SRS triggering signaling aperiodic to the Article 2, The UE is based on the aperiodic SRS triggering signaling of the Article 2 and sends SRS for the second time to the base station, and the UE is saved should be second The identification information for sending SRS is " 1 ", and saves this second and send the upgoing wave that at least two SRS are used respectively when sending SRS Beam information.The rest may be inferred, and when the bit number of the identification information is 1, the aperiodic SRS that the base station is sent to the UE is touched Identification information " 0 " or " 1 " is carried in signaling, as shown in Fig. 2, Fig. 2 is base station provided in an embodiment of the present invention non-week twice Phase triggers the schematic diagram that UE sends SRS, and the following table 1 is the mapping table of the identification information and the number of UE transmission SRS.

Table 1: identification information

Identification information
		0	Corresponding 1st transmission SRS
1	Corresponding 2nd transmission SRS

Assuming that the UE sends M SRS to the base station each time, M is the integer more than or equal to 2.As M=8, When the i.e. described UE sends 8 SRS to the base station each time, the bit number of the SRS resource index is 3, i.e., is refered in particular to using 3 ratios Show a specific SRS, the following table 2 is the mapping table of SRS resource index and 8 SRS.

Table 2:SRS resource index

SRI information
		000	SRI=1
001	SRI=2
		010	SRI=3
011	SRI=4
		100	SRI=5
101	SRI=6
		110	SRI=7
111	SRI=8

Illustrated based on the example above, when the target identification information that the base station is carried into the uplink scheduling information of the UE For " 1 ", when SRS resource index is " 010 ", the UE determines SRS in the SRS of second of transmission according to the target identification information Resource index is that " 010 " corresponding SRS is target SRS, that is, determines that the 3rd SRS that second sends is target SRS, the UE The uplink beam for further determining that the target SRS uses according to the uplink beam information that uses of SRS is sent for second of preservation For target uplink beam.

It should be noted that as the SRS that target identification information correspondence is sent at least twice, described in the UE determination Sending the last corresponding SRS of the index of SRS resource described in SRS that sends in SRS at least twice is target SRS.

For example, further, mark letter is carried when base station SRS triggering signaling aperiodic to the Article 3 It ceases " 0 ", the UE is based on the aperiodic SRS of the Article 3 and triggers signaling to the base station third time transmission SRS, and the UE is saved should Second of identification information for sending SRS is " 0 ", and saves and send what at least two SRS were used respectively when the third time sends SRS Uplink beam information.

When the target identification information that the base station is carried into the uplink scheduling signaling that the UE is sent is " 0 ", SRS resource When index is " 101 ", since the corresponding UE sends SRS to the target identification information " 0 " for the first time simultaneously and third time is sent out It send SRS, the UE to determine that the target identification information " 0 " is corresponding and sends SRS in the SRS that the last time sends in SRS twice Resource index is that " 101 " corresponding SRS is target SRS, that is, determines that the 6th SRS is target SRS in the SRS of third time transmission.

The UE saves identification information when sending SRS each time, comprising:

In the embodiment, the UE receives the period SRS configuration information that the base station is sent, and is then based on the period SRS configuration information periodically sends SRS to the base station, and the period SRS configuration information may include what the base station configured Period and sub-frame offset.The mode that the UE saves identification information when sending SRS each time specifically can be, according to default Rule is identified number to the SRS sent each time, and saves this time when sending SRS each time and send the corresponding mark of SRS Knowing number is the identification information that this time sends SRS, wherein the rule that the preset rules are the UE and the base station is made an appointment Then, such as according to the bit number of System Frame Number and identification information when sending SRS every time identifier number is determined.

For example, it is assumed that the bit number of identification information is 2, then the value of identification information is 0~3, as shown in figure 3, institute When stating UE first time transmission SRS, saving the corresponding identification information of first time transmission SRS is " 00 " (i.e. identifier number is 0), and The uplink beam information that 8 SRS sent when saving first time transmission SRS are used respectively.The UE sends SRS for the second time When, it is " 01 " (i.e. identifier number is 1) that the corresponding identification information of SRS should be sent for second by, which saving, and saves and should send for second The uplink beam information that 8 SRS sent when SRS are used respectively.When the UE third time sends SRS, third time hair is saved Sending the corresponding identification information of SRS is " 10 " (i.e. identifier number is 2), and saves the third time and send 8 SRS sent when SRS The uplink beam information used respectively.When the 4th transmission SRS of the UE, the corresponding mark letter of the 4th transmission SRS is saved Breath is " 11 " (i.e. identifier number is 3), and saves the uplink beam that 8 SRS sent when sending SRS are used respectively the 4th time Information.It is the corresponding relationship of above-mentioned identification information and identifier number shown in the following table 3, the SRS resource is indexed and sent out each time The corresponding relationship of 8 SRS sent is identical as upper table 2.

Table 3: identifier number

Identification information	Identifier number
		00	0
01	1
		10	2
11	3

Illustrated based on the example above, when the target identification information carried in the uplink scheduling signaling that the base station is sent is " 01 ", when SRS resource index is " 010 ", the UE can determine second of SRS sent according to the target identification information The 3rd SRS is target SRS in (i.e. identifier number be 1 SRS).

In the embodiment, the UE is specific according to the mode that preset rules are identified number to the SRS sent each time Can be according to the bit number of identification information and send each time the corresponding System Frame Number of SRS to the SRS sent each time into Line identifier number.Specifically, it is assumed that it is K that certain, which once sends the corresponding System Frame Number of SRS, and the UE can be according to formula [K mod (2^L)] determine the corresponding identifier number of the secondary SRS, identification information is further then determined according to determining identifier number, wherein " mod " is to take the remainder operation, and L is the bit number of identification information.

It is understood that when base station determines that the optimal SRS of the quality of reception is target SRS, it also can be according to described default Rule determine the target identification information, then by the target identification information carrying institute is sent in uplink scheduling signaling State UE.
