Various aspects discussed in this article promote joint BS and the UE wave beam that is exceedingly fast in 5G mmWave cellular system adaptive It answers.Compared with traditional wave beam adaptive technique, various technologies used in the examples can be in single Transmission Time Interval (TTI) it is adaptive that wave beam is provided in.

With reference to Fig. 2, shows and be related in millimeter wave (mmWave) wireless system according to various aspects described herein The adaptive exemplary scene of wave beam.In the figure 2 example, the mmWave channel between base station (BS) and user equipment (UE) includes Two paths (202 and 204), wherein the active path through the communication in 210-230 indicated by an arrow.At 210, BS and UE are Its wave beam is focused on reflection path 202, to carry out very high data rates communication, wherein corresponding wave beam be indicated as b1 and u1.At 220, reflection path 202 is blocked (for example, as the artificial obstruction as shown in 220, or since reflector moves Move), to significantly reduce the quality in path 202.Therefore, as shown in 230, BS and UE can retract using sub-optimal path 204.In various aspects described herein, such technology can be used so that in single TTI, BS and UE can (for Link including a pair of of BS wave beam and UE wave beam) detect the variation of link-quality, and correspondingly make its wave beam (by wave beam b2 and U2 is indicated, is respectively used to BS and UE) it is adapted to the associated link in the path 204 in the example with Fig. 2.

Sector scanning process is repeated dependent on BS and UE for combining the adaptive traditional technology of BS and UE wave beam.As a result, It can be adapted to due to channel/link (selected wave beam to) mass change in BS and UE or in cases of a jam again Establishing communication link, there are sizable delays before (for example, about 40-200ms).This, which not only reduces handling capacity and increases, prolongs Late, the additional energy in terms of and due to spending in sector scanning process, also increases the power consumption of mobile device.

However, UE can receive the phase at PDCCH (physical downlink control channel) in various aspects described herein Between intelligently identify the quality in different paths.When detecting the variation of obstruction or path quality in optimal path, UE can be with Instruction BS takes adequate measures and switches BS wave beam, and UE can correspondingly change UE wave beam.There is discussed herein various skills Art, the united beam that can promote to be exceedingly fast are adaptive.New sector scanning can not executed using the embodiment of this technology Promote united beam of the BS and UE in single TTI (for example, 0.4ms etc.) adaptive in the case where process.Based on being described herein The united beam that is exceedingly fast of technology can adaptively significantly improve handling capacity, delay and the power consumption characteristics of UE.

With reference to Fig. 3, the exemplary diagram of two-stage RF (radio frequency) beamforming architectures is shown, which can be by BS and/or UE It is used in conjunction with various aspects described herein.Two-stage RF beamforming architectures may include: that (i) has broad beam and low gain More than first (relatively small numbers) level-one sector, for the communication of low data rate control information (for example, PDCCH is passed Defeated, BCH (broadcast channel) transmission, ACK (hybrid automatic repeat-request (HARQ) confirmation) reception etc.) and/or with more low modulation The communication of order is more preferable；(ii) more than second (relatively large quantity) the second level sectors with narrow beam and high-gain, it is right It is more preferable in high data rate data communication (for example, there is more high modulation order etc.).In all fields, level-one sector and second level fan The quantity in area, which can change, (also, specifically, does not need in the example with Fig. 3 the number described for illustrative purposes Matching), although there may be multiple (for example, dozens of, more or less, etc.) second level fans generally for each level-one sector Area.

In all fields, the technology being discussed herein can promote fast joint wave beam certainly in any of two scenes It adapts to.

In the first scene, during the scanning process of initial sector, BS and UE identification are corresponding from different reflection paths Two or more second level sectors are to (for example, the sector second level UE and the sector associated second level BS, etc.).For example, in Fig. 2 In, BS and UE can identify that second level corresponding with path 202 and 204 sector is to (b1, u1) and (b2, u2) respectively.

In the second scene, UE can identify corresponding from the different paths sector two or more second levels UE (for example, During initial acquisition or sector scanning process), but the sector corresponding second level BS be not required to it is to be identified.For example, in Fig. 2, U1 and u2 is only identified at UE.

In some respects, high-level, it is adaptive that fast joint BS and UE wave beam can be executed as follows.UE can be used one Grade UE comes sector to receive PDCCH from BS.UE can estimate the quality of the reflection path of the sector its second level UE.If (for example, second level The sector UE etc.) quality of reflection path changes, then and UE can initiate that wave beam is adaptive, this can according to technique described herein To depend on special scenes.

In the first scene (for example, wherein BS and UE has identified multiple associated second level sectors equities), UE can be with BS is notified to use the sector second level BS (that is, as determined from sector second level UE etc.) for corresponding to current best reflection path, And UE can update accordingly the sector second level UE.

In the second scene (for example, wherein UE but be not necessarily BS and identified multiple second level sectors etc.), UE can be with It is changed to the BS notice sector second level UE, and BS can be requested to initiate the specific second level BS sector scanning process of level-one, so as to BS identification corresponds to the sector best second level BS of the sector updated second level UE.

With reference to Fig. 4, showing can be in conjunction with the example subframe structure that various aspects described herein uses.Son in Fig. 4 Frame can have the TTI (for example, 0.4ms, 0.8ms etc.) of TTI (for example, 1ms) shortening relative to legacy system.Example subframe It may include the PDCCH (e.g., including n symbol) at the beginning of subframe, for sending DL (downlink to one or more UE Link) data PDSCH (physical down link sharing channel), DL and UL (uplink) transmission between GP (protective time slot) Or gap, and may include the one or more in response to the DL data sent via PDSCH for the part of UL transmission ACK and/or one or more NACK (one or more HARQ negative confirmation).In all fields, associated with the sector second level UE The determination of quality can be based on the received PDCCH of subframe via example subframe in such as Fig. 4 etc, and when UE is determined When should update the second level sector UE, the sector second level BS (for example, via first scene or the technology of the second scene etc.) is updated to BS UE request can be used as in same subframe UL transmission (for example, in conjunction with ACK/NACK) sent by UE.

With reference to Fig. 5, shows and joint BS and UE wave beam adaptive process is related to according to various aspects described herein One exemplary scene.The example of Fig. 5 depicts in response to path blocks or causes and the sector predominant secondary UE and predominant secondary BS Quality on the associated current communication path in sector (upper path in each of 500-530 in the example of Fig. 5) The first scene of combination (for example, wherein BS and UE has identified multiple associated second level sector equities) of other situations to degrade Joint BS and UE wave beam it is adaptive.However, as described in more detail below, can in conjunction with the second scene (for example, wherein UE but It is not necessarily BS and has identified multiple second level sectors etc.) use similar technology.

At 500, the sector level-one BS is can be used to send PDCCH in BS, and the sector level-one UE can be used to connect in UE Receive PDCCH.Since BS and UE use level-one sector, even if UE also can receive control when optimal path is blocked Information.When receiving PDCCH, UE can estimate to include current communication path and other one or more paths (in the example of Fig. 5 In show two paths) including multiple paths (and therefore sector corresponding second level UE) quality.In all fields, may be used To use AoA (angle of arrival) algorithm for estimating or the other technologies being discussed herein to carry out the estimation of execution route quality.

At 510, since previous optimal path (upper path in the example of Fig. 5) is blocked and BS has not known It blocks, therefore by it, previously (for example, current main) sector second level BS had been used to send DL signal to UE BS.This may cause UE The information at place is lost, and unrelated with its sector (level-one or second level).

At 520, in the first scene, UE can send DL NACK, and can also notify to work as to BS and be led to UE The sector updated second level BS to be used when letter.BS reception can occur on the sector level-one BS, and UE transmission can be sent out Life is on the new sector predominant secondary UE.

At 530, BS can dispatch retransmission (or rescheduling UE in another subframe) immediately and can benefit UE is transmitted data to updated (new the is main) sector second level BS.

As described above, in some respects, UE can be used the sector level-one UE and carry out PDCCH reception.By using wide one The grade sector UE carries out PDCCH reception, and UE never can receive signal with path.Therefore, even if a path is blocked, still may be used To receive control information (note that control information is usually sent with minimum MCS (modulation and encoding scheme)).

However, some UE (for example, UE at cell edge) may not be available the wide sector level-one UE to be controlled Information receives, because link budget may not close.As described in more detail below, in all fields, it can be used for Fast joint BS and UE adaptive substitute technology, independent of use the sector level-one UE UE carry out PDCCH reception.

In some respects, UE AoA algorithm for estimating can be used when receiving PDCCH assess its access path (and because The sector this second level UE) quality.

In other respects, multiple portions can be divided by the PDCCH data that BS is sent, for example, m part.With reference to Fig. 6, showing can be in conjunction with the example m part PDCCH that various aspects described herein uses.In the first portion, BS can be with It announces the UE that dispatches in current subframe, and can also identify and be stated in m-1 then which of partially part The definite scheduling of the UE of each scheduling.The sector its level-one UE can be used in UE, and to decode first part, (this is between all UE It is common) and belong to its part, and it is predetermined across one group to execute that redundancy section (other m-2 part) can be used The sector second level UE UE receive sector scanning.The process can permit UE and obtain about path quality (and accordingly, with respect to right The sector second level UE answered) up-to-date information, such as measured via SNR (signal-to-noise ratio) or SINR (the ratio between signal and interference plus noise) Deng.

In all fields, UE can assess the quality in different paths (and therefore corresponding second level sector to).If road Path quality changes (for example, the current sector predominant secondary UE no longer has best in quality etc. in the sector second level UE), then UE can To continue as follows.

(for example, the wherein known sector second level BS for corresponding to the sector second level UE at BS) in the first scene, UE can be with It indicates that BS updates the sector its second level BS during UL data and/or control transmission, and its second level UE fan can be updated accordingly Area.

(for example, wherein the one or more sector second level BS corresponding with the sector second level UE is at BS in the second scene It is not known, etc.), UE can notify the sector BS its second level UE to change and BS initiation level-one can be required specific Second level sends sector scanning.BS can be transmitted this information to during UL data/control transmission.

In addition, in some respects, (that is, using the sector level-one UE) can be widened to carry out using the wave beam not needed at UE The technology of PDCCH reception.In order to allow UE to obtain quality about different paths without using the sector level-one UE Information, BS can send secondary synchronization signal (SSS) etc. at the beginning of PDCCH on the sector its level-one BS.The SSS (s) is sent Duration it can be made to allow one or more UE in the upper execution in one or more of its sector scheduled second level UE Sector scanning.The quantity of duration or its used symbol that the SSS is sent can be declared during initial UE is attached, Or can be a part of BCH, it can be predefined, etc..Then, each UE can be in its sector scheduled second level UE Collection closes execution sector scanning, to obtain the information of the quality about the sector these second levels UE.If the sector second level UE of UE Quality changes, then UE can follow same technique discussed above come to BS notify the sector second level UE variation and at first It requests BS to update its second level sector or initiate the specific second level of level-one in the second scene in scape and sends sector scanning.
