Fig. 7 shows the Msg3 frame structure according to some embodiments of the present disclosure.Frame structure 710 may include have it is multiple The frame 712 of OFDM symbol (for example, 14 OFDM symbols), and Msg3 transmission window 724 can be accorded with across the OFDM of frame 712 Number subset.Frame structure 710 can be substantially similar to frame structure 610 and/or frame structure 620.

In some embodiments, other frame structures of Msg3 may include the Msg3 data sent together with long CP and DMRS, and mark-hold can advantageously be supported to extract window.Different UE can be by different panels (for example, different ENB panel) it receives, and specific symbol extraction window can be supported for Msg3 reception.

For example, symbol number 0 may include use when signal reaches earlier in the scene 720 such as reached earlier In the complete DMRS of channel estimation.ENB can then calculate house error, and the symbol with even number index may include Whole DMRS and/or data information, these DMRS and/or data information can be used for data demodulation.Alternatively, when signal is all When reaching later in the scene 740 such as arrived later, the symbol with odd number index may include complete DMRS and/or number It is believed that breath, these DMRS and/or data information can be used for data demodulation.

Wherein, N₁The number of the OFDM symbol for Msg3 transmission be can be (for example, describing for Msg transmission window 714 11 OFDM symbols)；N_CPIt can be CP length；N_OFDMIt can be OFDM length.

In some embodiments, it is measured according to DL wave beam, UE can calculate the time difference between two clusters (for example, t₁- t₂).For some embodiments, two or more indicators can be configured together with contention resolution scheme by eNB, in which: instruction The first value (for example, value " 00 ") of symbol can indicate signal arrival on time or " correct "；The second value of indicator is (for example, value " 01 ") it can indicate that time of arrival (toa) is later；The third value (for example, value " 10 ") of indicator can indicate time of arrival (toa) It is relatively early.(the 4th value of indicator, for example, value " 11 " can retain).

For some embodiments, UE can send one based on the TA obtained in RAR during an OFDM symbol PRACH or xPRACH sequence.NW/UE wave beam can obtain link in PRACH the or xPRACH stage.ENB can calculate house TA error, and house TA error can be indicated to UE.After UE receives the 2nd RAR, UE can be based on from the two TA (examples Such as, the TA obtained in RAR and the house TA error obtained in the 2nd RAR) the timing adjustment amount derived sends Msg3.

In some embodiments, the first RAR can be simplification TA only comprising TA value, and the 2nd RAR may include entirely RAR field.For some embodiments, time-domain resource, frequency domain resource, and/or the generation transmitted for additional PRACH or xPRACH Code resource can be configured or can be predetermined by eNB.

Fig. 8 shows the wave beam aggregation scene according to some embodiments of the present disclosure.Scene 800 may include the first eNB 810, the 2nd eNB 820 and UE 830.First eNB 810 can be service eNB, while the 2nd eNB 820 can be assistant eNB.UE 830 can be wirelessly communicated with the first eNB 810 and the 2nd eNB 820 respectively via first panel and second panel.

In addition, can be polymerize using wave beam in scene 800, wherein different transmission blocks can be via different Tx-Rx waves Beam sends and/or receives to link.In various embodiments, it can use central scheduler or do not utilize central scheduler real Existing wave beam polymerization.For independent scheduler situation, wave beam polymerization can operate in the way of being similar to more connectivity, and Different eNB can dispatch different directions.For example, service eNB can dispatch DL transmission, while assistant eNB can dispatch UL Transmission.

Fig. 9 is shown according to the scene interfered between the panel in the polymerization of the wave beam of some embodiments of the present disclosure.Scene 900 It may include the first eNB 910, the 2nd eNB 920 and UE 930.First eNB 910 can be service eNB, while second ENB 920 can be assistant eNB.UE 930 can via first panel and second panel respectively with the first eNB 910 and second ENB 920 is wirelessly communicated.

Although may exist a degree of physical isolation between the first panel of UE 930 and the second panel of UE 930, But if UE 930 is in cell edge region, problem can be become by interfering.In this case, UL transimission power (for example, The power of 932 related UE 930 is transmitted with the UL sent from interference panel) it can be transmitted due to power control close to maximum UL Power.Meanwhile DL receive power (for example, be disturbed the received DL of panel and transmit 912 related UE 930 power) may It is relatively low.Then IPI can be observed in being disturbed in panel for UE 930.

Due to various factors, the reduction of IPI may will form challenge.Firstly, multi-beam operation can be used for DL and UL.The Two, UL and DL can be directed to different eNB, and cause to observe between UL and DL since propagation delay may be different Biggish timing gap, and network may be asynchronous (for example, not being synchronized).Third, UE can have two with Upper effective aerial panel, therefore Tx antenna port and antenna element can be different from the sum of Rx antenna port and antenna element.

(for example, for wave beam polymerization) multi-beam operation can be advantageously reduced in the various mechanism and method being discussed herein IPI, wherein wave beam can reach the different panels of UE from different directions.It in some embodiments, can be by being assisted between eNB Tune degree enhances to reduce IPI.For some embodiments, can avoid dispatching simultaneously not by servicing multiple eNB of UE simultaneously Same link transmission (for example, avoiding the link transmission for dispatching the different directions UL/DL simultaneously), to reduce IPI.

In addition, the UE IPI that the various mechanism and method that are discussed herein can contribute to multi-beam operation is eliminated.Some In embodiment, channel estimation associated with IPI can be performed and (can carry out in UE radio frequency (RF) front end calibration phase).It is right In some embodiments, the estimation channel coefficients in time domain or frequency domain can be stored in IPI cancellation module.In some embodiments In, IPI is eliminated can be performed if by various conditions (for example, IPI grade by can be predetermined threshold) triggering.

UE can have such antenna structure, which has mutiple antennas panel, and these antenna panel It can be directed to different directions respectively.Table 1 below provides the antenna elements for a panel.

Table 1: the antenna element for a panel

Although there are some isolation between different aerial panels, if from interference panel transmission power compared with Greatly, IPI is still larger.For example, sending power can for example be compared due to power control if UE is in cell edge region It is larger.In addition, wave beam polymerization can be used for cell edge UE.

In some embodiments, IPI can be inhibited by coordinated scheduling.Multiple eNB can be directed to simultaneously a UE's All panels dispatch identical direction (for example, UL or DL).

But the validity of coordinated scheduling can reduce in some cases.For example, in the case where asynchronous network, for Dispatching the same direction will form challenge simultaneously for multiple eNB, although wave beam polymerization can be used for asynchronous network.In addition, due to Propagation delay, even if network is synchronized and coordinated scheduling is utilized, since TA, IPI still will appear.Therefore, UE can have Sharply using the mechanism and method for inhibiting IPI.

Figure 10 shows the memory construction for channel according to some embodiments of the present disclosure.Memory construction 1000 It may include the channel estimation 1010 between multiple stored each Tx wave beam/Rx wave beams pair from different channels.

In some embodiments, IPI can be inhibited by UE receiver.According to an option, UE can pre-define (or pre- First determine) its Tx wave beam and Rx wave beam grid, and estimate the letter between each Tx wave beam/Rx wave beam pair from different panels Road.Therefore, the time domain channel of each Tx wave beam/Rx wave beam pair and/or frequency domain channel (or channel estimation) can be stored in by UE In memory.

For example, with reference to memory construction 1000 (it can be used for dual platen UE or UE at least two panels), There may be R Rx wave beam and T Tx wave beam, and each channel H_a,b,c,dIt can indicate with panel a (in R Rx wave beam ) the associated channel of (in T Tx wave beam) Tx wave beam number d of Rx wave beam number c and paired panel b.

It should be noted that eliminating for IPI, various embodiments, which can only consider to correspond to, potentially results in significant IPI Wave beam to those of channel coefficients.In addition, can just apply IPI removing method only when sizable IPI occurs.It changes Yan Zhi may not be needed IPI elimination if the IPI grade predicted is very small.Therefore, various embodiments can combine IPI It eliminates opening-shutdown mechanism (for example, opening-shutdown mechanism based on threshold value).

The channel stored can be the channel in frequency domain or time domain.In some embodiments, the channel stored can be with Including two vectors: a vector is that (delay of each tap can be quantized for the delay vector of the delay for indicating each tap Or cannot be quantized), another vector is the channel coefficients of each tap.Then, since UE can know the face of being disturbed Channel and transmission signal between plate and interference panel, it is possible to carry out interference elimination in time domain or frequency domain.Note that if can With the acknowledgement channel reciprocity between panel, then the grid of the wave beam in each panel is identical, and channel needs are stored as only using In a direction (for example, H_0,1,x,y)。

In the time domain, the reception signal of an antenna port can be given by:

Wherein, h_j[n] can indicate the equivalent Wave beam forming channel from service eNB in Tx antenna port j；x_j[n] can be with Indicate the DL time-domain signal in Tx antenna port j；h_j' [n] may refer between the equivalent Wave beam forming panel in Tx antenna port j Channel；x_j' [n] can indicate the UL time-domain signal in Tx antenna port j；σ_j[n] can indicate interference plus noise；N_TxIt can be Service the number of the Tx antenna port in eNB；N_Tx' it can be the number for interfering the Tx antenna port in panel.

In order to reduce the interference in time domain, the reception signal in each antenna port can be given by:

Wherein, hj " [n] can indicate that the antenna port j's from interference panel prestores channel.

In a frequency domain, the reception signal in a subcarrier can be obtained by following formula:

Y=HX+H'X'+N
