To solve the above problems, the user equipment in the embodiment of the present invention is obtained and includes the preferred wave beam of preferred beam combination Combination of sets, and then simply in the preferred beam combination, transmit upward signal, signal transmission in the preferred beam combination Quality is higher than default quality threshold, and need not be directed to all beam combinations and carry out the uplink signal transmissions of all standing, therefore can be with The uplink signal transmissions and unnecessary energy consumption signaling consumption of invalid redundancy are avoided, the efficiency of uplink signal transmissions is improved.

It is understandable to enable the above objects, features and advantages of the present invention to become apparent, below in conjunction with the accompanying drawings to the present invention Specific embodiment be described in detail.

The method that Fig. 1 shows a kind of uplink signal transmissions in the embodiment of the present invention, below with reference to Fig. 1 to methods described It is discussed in detail step by step, methods described may include steps of：

Step S11：Obtain preferred beam combination collection.

In specific implementation, the preferred beam combination collection belongs to all of beam combination structure between user equipment and base station Into set, and the preferred beam combination concentrates and includes preferred beam combination, the signal transmission in the preferred beam combination Quality be higher than default quality threshold.In other words, in preferred beam combination the quality of signal transmission than user equipment and base Major part between standing in all of beam combination will be more preferably higher.

Such as, user equipment has the two wave beams of beam1 and beam2, and base station has the two ripples of beam3 and beam4 Beam, between user equipment and base station all of beam combination be beam1beam3, beam1beam4, beam2beam3 and Beam2beam4, the signal transmission quality in these beam combinations is reduced successively, then preferred beam combination can be Beam1beam3 and beam1beam4, beam1beam3 and beam1beam4 the two beam combinations may be constructed preferred wave beam group Intersection.

In specific implementation, on obtaining preferred beam combination collection, there can be various methods.In one embodiment of the invention In, user equipment can receive the preferred beam combination collection determined by the base station, and in detail, user equipment can be with Upward signal is transmitted in all of beam combination between the user equipment and base station, the base station is according only in each wave beam The quality that the upward signal is received in combination, or simultaneously according to the preferred default size of beam combination collection, obtain including preferably The preferred beam combination collection of beam combination, user equipment directly receives preferred beam combination collection determined by base station.

In specific implementation, for the quality that base station receives according only to the upward signal in each beam combination, obtain To the preferred beam combination collection including preferred beam combination, such as base station sets a quality threshold, as long as upward signal is received Quality is more than the beam combination of the threshold values as preferred beam combination, and preferred beam combination collection is constituted with this.

In specific implementation, for the quality that base station receives according to the upward signal in each beam combination, and together When according to the preferred default size of beam combination collection, obtain including the preferred beam combination collection of preferred beam combination, such as base station It is determined that it is preferred that the size of beam combination collection is 3, i.e., there are 3 preferred beam combinations in preferred beam combination collection, then can own Beam combination carry out quality from excellent to bad arrangement according to signal receiving quality, take the preferable wave beam group of first three signal quality Close to constitute preferred beam combination collection.

In an alternative embodiment of the invention, on obtaining preferred beam combination collection, the base can be monitored by user equipment The downstream signal stood, so voluntarily according only to the base station downstream signal monitoring quality or simultaneously according to preferred beam combination Collect default size and obtain the preferred beam combination collection.

In specific implementation, for the matter that user equipment is monitored according only to the downstream signal in each beam combination Amount, obtains including the preferred beam combination collection of preferred beam combination, such as user equipment sets a quality threshold, as long as descending Signal monitoring quality is more than the beam combination of the threshold values as preferred beam combination, and preferred beam combination collection is constituted with this.

In specific implementation, for the quality that user equipment is monitored according to the downstream signal in each beam combination, And obtain including the preferred beam combination collection of preferred beam combination, such as according to the preferred default size of beam combination collection simultaneously User equipment determines that the size of preferred beam combination collection is 5, i.e., have 5 preferred beam combinations in preferred beam combination collection, then may be used Quality from excellent to bad arrangement is carried out according to signal monitoring quality with by all of beam combination, preceding 5 signal qualitys is taken preferable Beam combination constitute preferred beam combination collection.

Because situation about being communicated between user equipment and base station is changing always, the preferred beam combination at moment before possibility It has not been the preferable beam combination of signal transmission quality at current time.Such as, at the t1 moment, beam1beam3 and Signal transmission quality in beam1beam4 the two beam combinations is higher.But because user equipment is in mobile status, use Family equipment changes with the relative position of base station, at the t2 moment, beam1beam3 and beam2beam3 the two beam combinations On signal transmission quality uprise, the reduction of signal transmission quality in beam1beam4 beam combinations.

Therefore in specific implementation, in order to a certain extent ensure preferred beam combination for signal transmission quality is higher Beam combination, improves the efficiency of uplink signal transmissions, and user equipment can periodically carry out the preferred beam combination of acquisition The operation of collection, namely user equipment can again obtain the preferred beam combination in current time meaning every default duration Collection.

In specific implementation, the reception condition of the upward signal that base station can be transmitted according to current reception user equipment, To judge the quality of preferred beam combination, therefore user equipment can also be rebuild the requirement of the sign from the base station is received It is preferred that during the notice of beam combination collection, performing the operation for obtaining preferred beam combination collection.

In specific implementation, require to update the notice of preferred beam combination collection when the sign from the base station is received, And when not including indicating the information of updating type in the notice, user equipment can update the complete of the preferred beam combination collection Portion, it is also possible to update the part of the preferred beam combination collection.Therefore, user equipment can be carried out neatly according to actual conditions Update, the efficiency that preferred beam combination updates can be improved.

In specific implementation, preferred beam combination collection is updated when user equipment receives the sign requirement from the base station Notice, and it is described notice also include：Indicate updating type information when, can according to it is described instruction updating type information, Perform and operated with the renewal corresponding to the updating type.Such as, the notice indicates updating type all to update, then user The whole preferred beam combination collection of renewal of the equipment.Again such as, the notice indicates updating type to be updated for part, then user equipment Preferred beam combination collection can partly be updated.

In specific implementation, on the part for updating the preferred beam combination collection, there can be various methods.Such as The combination of the default wave beam of the user equipment and all wave beams of base station can be updated, and can also such as update the base station Default wave beam and user equipment all wave beams combination.

It is understood that the mode of the part due to updating the preferred beam combination collection has various, and specifically select The mode that any part updates, also can be to be indicated by the notice by base station in an embodiment of the present invention, User equipment can directly perform corresponding renewal and operate according to the instruction or notice.In another embodiment of the present invention In, base station simply can also carry out the preferred beam combination collection of part renewal by instruction user equipment, specifically be updated from which kind of part Mode voluntarily selected by user equipment.

Step S12：In the preferred beam combination, upward signal is transmitted.

In specific implementation, after preferred beam combination is determined, user equipment can be in preferred beam combination On, upward signal is transmitted, so can both ensure that base station receives upward signal, and without between the user equipment and base station Upward signal is transmitted in all beam combinations, therefore the efficiency of uplink signal transmissions can be improved.

In an embodiment of the present invention, the upward signal can be up mobility reference signal, and described up Mobility reference signal is suitable to up mobility control.It is understood that those skilled in the art according to actual needs, also may be used It is the other types of signal in addition to up mobility reference signal, the specific type of upward signal to set the upward signal Protection scope of the present invention is not construed as limiting.

To cause those skilled in the art to more fully understand and realizing the present invention, Fig. 2 is shown in the embodiment of the present invention The schematic flow sheet of the method for another uplink signal transmissions, as shown in Fig. 2 methods described may include steps of：

Step S21：Receive the upward signal that user equipment is transmitted in all of beam combination.

Step S22：According only to the quality that the upward signal in each beam combination is received, or simultaneously according to preferred ripple The default size of beam combination of sets, obtains including the preferred beam combination collection of preferred beam combination, and transmits to the user equipment.

In specific implementation, on the quality or excellent that base station receives according to the upward signal in each beam combination The default size of beam combination collection is selected, obtains including the preferred beam combination collection of preferred beam combination, there can be various methods.

Preferred wave beam such as can be determined only according to the quality of the upward signal reception in each beam combination Combination, specifically can pre-set quality threshold, as long as signal transmission quality is not less than the quality threshold for pre-setting The beam combination of value, can belong to the preferred beam combination collection.

Again such as, the upward signal is received in each beam combination quality and preferred beam combination collection can be combined pre- If size the two factors determine preferred beam combination collection, can specifically pre-set the size of preferred beam combination collection, both The quantity of preferred beam combination therein, if it is 2, all of ripple that will can be then constituted between user equipment and base station The signal transmission quality of Shu Zuhe is sorted from high to low, is taken preceding 2 beam combinations and is constituted the preferred beam combination collection.

Step S23：The upward signal that reception is transmitted from the user equipment in the preferred beam combination.

In specific implementation, when the upward signal is not received in default duration, it is characterized to a certain extent Preferably beam combination has not been the preferred beam combination on current time determined by preceding, therefore can notify the user equipment Rebuild the preferred beam combination collection.

In specific implementation, when it is determined that the matter of the upward signal that the user equipment is transmitted in the preferred beam combination When amount is unsatisfactory for default signal transmission quality condition, can notify that the user equipment updates the preferred beam combination collection.

In specific implementation, in addition to notifying the user equipment to update the preferred beam combination collection, base station may be used also To notify that the user equipment updates the updating type of the preferred beam combination collection, then user equipment is executable and updates Type updates operation to corresponding, therefore can simplify the treatment of user equipment side.

In specific implementation, when it is determined that the matter of the upward signal that the user equipment is transmitted in the preferred beam combination When amount meets the signal transmission quality condition, transmitted in the preferred beam combination according to the user equipment for receiving Upward signal, judge whether need to the user equipment send control feedback information；When it is determined that needing to be set to the user Preparation send control feedback information when, to the user equipment send control feedback information so that user equipment can according to work as Preceding communication resource situation carries out corresponding adjustment.

In specific implementation, when it is determined that controlling feedback information without being sent to the user equipment, can notify described The combination of user equipment current beam is available and keeps preferred beam combination collection.

At present, upward signal is transmitted on all possible UE lateral beams and base station side beam combination, can be produced a large amount of Invalid redundant upstream signal transmission, and bring unnecessary energy consumption and signaling consumption.

And the user equipment in the embodiment of the present invention is obtained and includes the preferred beam combination collection of preferred beam combination, and then only It is in the preferred beam combination, to transmit upward signal, the quality of signal transmission is higher than default in the preferred beam combination Quality threshold, and without carrying out the uplink signal transmissions of all standing for all beam combinations, therefore invalid redundancy can be avoided Uplink signal transmissions and unnecessary energy consumption signaling consumption, improve uplink signal transmissions efficiency.

To cause that those skilled in the art more fully understand and realize the present invention, Fig. 3 is shown one in the embodiment of the present invention The interactive schematic diagram of the method for uplink signal transmissions is planted, in figure 3, user equipment receives described excellent determined by the base station Select beam combination collection.Fig. 4, Fig. 5 and Fig. 6 sequentially show the determination of a kind of preferred beam combination collection in the embodiment of the present invention Process schematic, wherein：It is that signal sends that T is characterized for UE sides, and it is that signal is received that R is characterized for UE sides, and O is characterized It is preferred that beam combination.With reference to shown in Fig. 3, Fig. 4, Fig. 5 and Fig. 6, methods described is described in detail, methods described can be with Comprise the following steps：

Step S301：Upward signal is transmitted in UE all standings.

In specific implementation, when effective preferably base station lateral beam and UE lateral beam combination of sets is lacked, UE can be selected UE The base station lateral beam selected in all presence transmits upward signal with combining all standing with UE lateral beams.

As shown in Figure 4, UE sides are configured with 3 wave beams, respectively beam1, beam2 and beam3, and base station side configures 4 Wave beam, respectively beam1, beam2, beam3 and beam4, therefore, UE sides and all 12 wave beam groups that may be constructed of base station side Closing to be：UE sides beam1 and base station side beam1, UE side beam1 and base station side beam2, UE side beam1 and base station side Beam3, UE side beam1 and base station side beam4, UE side beam2 and base station side beam1, UE side beam2 and base station side beam2, UE Side beam2 and base station side beam3, UE side beam2 and base station side beam4, UE side beam3 and base station side beam1, UE side beam3 The composition more than is needed with base station side beam2, UE side beam3 and base station side beam3 and UE side beam3 and base station side beam4, UE 12 beam combinations on transmit upward signal, to ensure effective transmission of upward signal.

Step S302：Base station draws preferred beam combination collection.

In specific implementation, for all standing uplink signal transmissions that UE is implemented, base station can be by judging what is received The quality of uplink signal transmissions, knows the base station side wave that the base station lateral beam of all presence can align in being combined with UE lateral beams Beam and UE lateral beams combination of sets and wherein each quality condition for combining, the so-called base station lateral beam that can be alignd and UE side waves Shu Zuhe, that is, the beam combination of data effectively transmitting-receiving can be realized.Then base station side can be based only on above-mentioned quality letter Breath, or the preferred base for needing to feed back to UE can also be generated according to the constraints of preferred beam combination collection size simultaneously Stand lateral beam and UE lateral beam combination of sets.Also, preferred base station lateral beam and UE lateral beams combination of sets can by one or A plurality of preferred beam combination is constituted, and every preferred beam combination includes corresponding UE lateral beams and base station lateral beam.It is preferred that wave beam The size of combination of sets is not construed as limiting to protection scope of the present invention.

As shown in Figure 5, base station side detects the upward signal of UE transmission in some beam combinations, such as in UE sides The beam combination of beam1 and base station side beam1, the beam combination of UE sides beam1 and base station side beam2, UE sides beam2 and base station The beam combination of side beam1, the beam combination of UE sides beam2 and base station side beam4, the ripple of UE sides beam3 and base station side beam2 The upward signal of UE transmission is detected in the beam combination of Shu Zuhe and UE sides beam3 and base station side beam4, can be compared and be sentenced The signal transmission quality of disconnected above beam combination, can be using which part combination as preferred beam combinations, such as by UE sides Beam1 and base station side beam1, UE side beam2 and base station side beam4, UE side beam3 and base station side beam2 and UE side beam3 and These beam combinations of base station side beam4 are used as preferred beam combination collection.

Step S303：Base station side notifies the preferred beam combination collection of UE.

In specific implementation, the lateral UE in base station feeds back preferred base station lateral beam and UE lateral beam combination of sets.Such as Fig. 5 institutes Show, base station is by preferred beam combination, i.e. UE sides beam1 and base station side beam1, UE side beam2 and base station side beam4, UE side These beam combinations feed back to UE with base station side beam4 for beam3 and base station side beam2 and UE side beam3.Due to preferred wave beam Combination of sets can transmit the preferred control of upward signal as UE, therefore can simplify the burden that UE transmits upward signal.

In specific implementation, base station side can feed back preferred base station lateral beam and UE lateral beam groups using various ways to UE Intersection,

Such as base station side can feed back preferred beam combination collection in the beam combination of current service for particular UE, compare again As base station side can notify the preferred beam combination collection of UE by way of paging.It should be noted that those skilled in the art's root According to being actually needed, it is also possible to notify the preferred beam combination collection of UE from other modes.

Step S304：UE sends upward signal on preferred beam combination collection.

In specific implementation, after UE obtains the preferred base station lateral beam and UE lateral beam combination of sets of base station side feedback, UE can With based on the preferred beam combination collection transmission upward signal.With reference to shown in Fig. 6, UE preferred beam set, i.e. UE beam1 with Base station side beam1, UE beam2 and base station side beam4, UE beam3 and base station side beam2 and UE beam3 and base station side Simplify transmission upward signal on beam4.

Step S305：Base station side judges whether to receive upward signal.

In specific implementation, UE meeting cyclical transmission upward signals, therefore base station side can decide whether to be periodically received Upward signal.

When base station does not receive upward signal in one section of duration, step S306 can be performed；Conversely, step can be performed Rapid S307.

Step S306：Base station side notifies that UE rebuilds preferred beam combination collection.

In specific implementation, when base station does not receive upward signal in one section of duration, what is determined before sign is preferred Beam combination collection has not been the preferable beam combination of transmission quality, namely base station side judges that presently preferred beam combination collection loses Effect, therefore base station can notify that UE rebuilds preferred beam combination collection.

In specific implementation, base station side can by the way of various ways notify that UE rebuilds preferred beam combination collection, than Such as can directly notify that UE rebuilds preferred beam combination collection by way of paging using direct advice method, i.e. base station side.

Again such as, any information can not be fed back to UE using indirect advice method, i.e. base station side, it is right that UE side joints can not receive Think that uplink fails when any feedback of upward signal, can start to rebuild preferred beam combination collection.Need explanation It is that those skilled in the art are according to actual needs, it is also possible to notify that UE rebuilds preferred beam combination collection from other modes.

Step S307：Base station side judges whether the quality of uplink signal on presently preferred beam combination collection meets default bar Part.

In specific implementation, when base station side receives upward signal, it can be determined that up on presently preferred beam combination collection When whether signal quality meets pre-conditioned, determine a need for updating preferred beam combination collection with this.

When the quality of uplink signal that base station side is determined on presently preferred beam combination collection meets pre-conditioned, step is performed S309；Conversely, step S308 can be performed.

Step S308：Base station side notifies that UE updates preferred beam combination collection.

In specific implementation, base station side can by the way of various ways notify that UE updates preferred beam combination collection, than Upgraded demand as base station side can feed back preferred beam combination collection in the beam combination of current service for particular UE.

Again such as, base station side can notify that UE updates preferred beam combination collection by way of paging.It should be noted that Those skilled in the art are according to actual needs, it would however also be possible to employ other manner notifies that UE updates preferred beam combination collection.

In specific implementation, the mode of preferred beam combination is updated on UE, it is possibility to have various.Such as, UE can be adopted Global update mode is used, i.e. UE triggering all standing upward signals update preferred beam combination collection.

Again such as, UE can use local updating mode, i.e. the local upward signal of UE triggerings updates preferred beam combination collection. When UE uses local updating, the selection or renewal of local upward signal can also have various ways.

UE lateral beams can be such as based only on, that is, update preferred UE wave beams and base station lateral beam group on certain UE wave beam Close, it is also possible to based on base station lateral beam, that is, update the preferred UE wave beams and base station side beam combination on certain base station lateral beam.
