In some embodiments, the UE device 100 may include additional components, such as memory/storage, display, camera, sensor, and/or input/output (I/O) interface, for example.

In addition, although the above illustrative discussion about the device 100 is based on a UE device, in various aspects, a similar device can be used in conjunction with a base station (BS) such as an evolved node B (eNB).

Although the beamforming gain can compensate for the greater path loss involved in transmitting at mid-band and/or high-band frequencies, the directional nature of beamforming transmission still introduces additional complications. For example, in the case of applying Tx beam sweeping to xPDCCH (5G (fifth generation) physical downlink control channel) with a common search space, repeated transmissions that may increase the system load and reduce the spectrum efficiency May be appropriate. In order to reduce the extra load of the system, the 5G system information block (xSIB) can be considered to operate without xPDCCH. In such cases, the xSIB transmission schedule can be indicated in the 5G master information section (xMIB).

If multiple cells transmit xSIB on the same time and frequency resources, severe inter-cell interference will be observed. In order to reduce this inter-cell interference and improve decoding performance for xSIB transmission, a mechanism for coordinating xSIB transmission among multiple cells, such as the one described in this article, can be used.

Various embodiments can use the techniques discussed in this article regarding the details of the xSIB design of the 5G system. In various aspects, these techniques may include details related to the transmission strategy(s) used by xSIB, and/or the mechanism(s) that can reduce inter-cell interference for xSIB transmission.

In each aspect, the size of the payload transmitted by xSIB may be different for different use cases and deployment scenarios. Therefore, the UE side can have information about the size of the payload to ensure proper demodulation and decoding.

In some aspects, there are N possible payload sizes for xSIB transmission (for example, N = 4, or larger or smaller numbers). The xMIB (5G Master Information Section) can include a field that can be used to indicate which payload size is used for xSIB transmission. Table 1 below shows an exemplary field that can be included in an xMIB to indicate one of four different payload sizes for an xSIB. Table 1: xSIB payload size

In addition, xMIB can also indicate the periodicity of xMIB transmission. For example, a field containing one or more bits can be used to indicate the xSIB transmission periodicity (for example, bit 0 can indicate that the xSIB transmission periodicity is 80 ms, and bit 1 can indicate that the xSIB transmission periodicity is 160 ms, etc. ).

Alternatively, the xSIB transmission periodicity may have a 1:1 correlation with the xSIB payload size. For a small payload size, a shorter transmission period can be defined, and for a large payload size, a longer transmission period can be defined. This option can help reduce the extra load of signaling in xMIB.

In some embodiments, the xSIB resource mapping is determined by the size of the payload. For example, for a large payload size, an xSIB block can occupy a full system bandwidth (for example, as shown in Figure 3, discussed below), and for a small payload size, an xSIB block can occupy a portion of the system bandwidth. Wide (for example, as shown in Figure 4, discussed below).

Please refer to FIG. 2, which shows an example method 200 for generating an xSIB according to various aspects described herein. The detailed design of one of this xSIB can be described as follows.

At 210, a code can be applied to the xSIB information bits (for example, it can include X bits, where X is any positive integer, such as one of the values indicated by a corresponding field in xMIB). In one example, a tail code cancellation convolutional code writer (TBCC) can be applied to xSIB. In the aspect, before encoding, a CRC (cyclic redundancy check) can be added to the xSIB information bit. In other instances, turbo codes or LDPC (low density parity checking) can be tolerated in xSIB information bits instead of TBCC.

其中n_s 是時槽索引，l是OFDM （正交分頻多工）符號索引，以及

是實體胞元ID。At 220, after writing the code, a specific cell scramble can be used to further randomize the interference. In the aspect, the stirring seed can be defined as a function of one or more of a physical cell ID, a subframe index, a time slot index, or a symbol index for xSIB transmission. In an example, this stirring seed can be found by Equation 1:

(1),

Where n _s is the time slot index, l is the OFDM (Orthogonal Frequency Division Multiplexing) symbol index, and

Is the entity cell ID.

At 230, a modulation type with a low modulation order (such as BPSK (Binary Phase Shift Keying) or QPSK (Quaternary Phase Shift Keying), etc.) can be used for modulation to ensure robust performance.

At 240, the modulated symbols generated at 230 can be mapped to the allocated resources, where the resource mapping mechanism can be as described below.

To allow for Tx (transmission) beam sweeping for xSIB transmissions, one xSIB transmission can span 1 or more OFDM symbols. Depending on the size of the payload, xSIB transmission can occupy a portion or a full system bandwidth. For the former situation, the xSIB payload size can be small.

In some embodiments, xSIB transmission occupies a full system bandwidth. In addition, different Tx beams can be applied on each OFDM symbol to ensure good cell coverage. Please refer to FIG. 3, according to the various aspects described in this article, an example of Tx beam sweeping when xSIB occupies full system bandwidth is shown. Please note that in the example of FIG. 3, the same xSIB information bits are transmitted in each OFDM symbol, but they are performed by different Tx beams.

In embodiments where xSIB occupies part of the system bandwidth, a localized or distributed transmission strategy can be used. The number of xSIBs in a symbol can be determined by the number of BRS (Beam Reference Signal) antenna ports. The Tx beams of each xSIB block can be one-to-one mapped to the Tx beams applied to the BRS. Please refer to FIG. 4, according to the various aspects described in this article, what is shown is an example of performing Tx beam sweeping on xSIB occupying part of the system bandwidth through localized or distributed resource allocation. The example shown in Figure 4 shows 4 Tx beams per symbol, and a total of 56 beams that can be applied to the BRS in a subframe. These 56 Tx beam sweeps can be applied to the xSIB sub-frame. In each aspect, the Tx beam mapping rules between xSIB and BRS can be predefined by specifications, so that the UE can select the best xSIB block(s) to be decoded. The xSIB block(s) available for the highest BRS-RP to be taken from the associated Tx beam.

Depending on the number of resource elements (RE) allocated for each xSIB block and the number of APs (antenna ports) used for xSIB transmission, the following different options can be provided for DM-RS (demodulation reference signal).

Please refer to FIG. 5, according to the various aspects described in this article, what is shown is an example of the DM-RS type used for single-port transmission when xSIB occupies 8 REs. Please refer to FIG. 6, according to the various aspects described in this article, what is shown is an example of the DM-RS type used for single-port transmission when xSIB occupies 12 REs. Please note that a similar pattern can be defined for dual-port xSIB transmission. As shown in Figure 7, according to the various aspects described in this article, the xSIB used for two APs is shown as an example when xSIB occupies 12 REs. DM-RS type. In various aspects, the DM-RS used for these two APs can be multiplexed according to a frequency division multiplexing (FDM) or a code division multiplexing (CDM) method.

In the case of CDM multiplexing between two APs, an Orthogonal Cover Code (OCC) can be applied to each AP, which can be defined in Table 2 as follows: Table 2: OCC for two APs

In an embodiment where SFBC (Spatial Frequency Block Code) is applied to xSIB transmission, two consecutive REs can be used for xSIB transmission.

In each aspect, in order to minimize the power consumption of the UE, a 1:1 Tx beam mapping relationship between synchronization signal/beam reference signal (BRS)/xPBCH and xSIB can be defined. In such an aspect, the xSIB decoding can only listen to one symbol as soon as the UE. Please refer to FIG. 8, according to various aspects described in this document, an example of a 1:1 Tx beam mapping relationship between xPBCH and xSIB transmission is shown. In one example, if a UE successfully decodes the xPBCH on the symbol #3 in the Tx beam group #1, it can use the same (multiple) Rx beams to decode the corresponding symbol #3 on the xSIB subframe XSIB.

The various aspects described herein can also facilitate alleviation of inter-cell interference associated with xSIB transmission. One or more of the following techniques can be used to (multiple times) xSIB transmission to reduce inter-cell interference.

，胞元#（3k）可在SF#47中傳送xSIB，胞元#（3k+1）可在SF#48中傳送xSIB，而胞元#（3k+2）可在SF#49中傳送xSIB。在其他態樣中，可依照一類似方式運用多於或少於3個群組。In some aspects, different cells can transmit xSIB in different frames and sub-frames (SF). In one instance, for

, Cell#(3k) can transmit xSIB in SF#47, cell#(3k+1) can transmit xSIB in SF#48, and cell#(3k+2) can transmit xSIB in SF#49 . In other aspects, more or less than 3 groups can be used in a similar manner.

In other aspects, different cells can transmit xSIB in the same subframe, but they are transmitted in different frequency resources. This technique is suitable for small xSIB payload sizes. In an example, the system bandwidth can be divided into N blocks (for example, N=3, or a larger or smaller number), which can be scattered or localized in the frequency domain. Depending on the physical cell ID, different cells can transmit xSIB in different blocks, which can create a re-use-N transmission pattern.

。In some aspects, the frame and/or subframe index used to transmit xSIB can be defined as a function of the physical cell ID, such as

.

In a further aspect, a field in the xMIB can be used to indicate the frame and/or subframe index used to transmit the xSIB. A group of frames and/or sub-frames used to transmit xSIB can be pre-defined in the specifications. This bit field in xMIB can be used to indicate which frame and/or subframe is used for xSIB transmission. The following Table 3 illustrates an example of the bit column indication in xMIB. Four example values are provided (in each aspect, more or less values can be provided). In this example, xSIB can be transmitted in one of the two frames, or can be transmitted within 20 ms. Please note that other examples can be directly extended from the examples listed below. Table 3 xSIB transmission timing

For example, the xMIB may indicate the size of the xSIB, such as via a payload size of the xSIB, a transmission duration of the xSIB, and so on. For another example, xMIB can indicate one or more parameters associated with the timing of (multiple) transmissions of xSIB, such as xSIB transmission periodicity, frame(s) and/or sub-information(s) Frame (xSIB will be sent during this period (which can be selected to minimize inter-cell interference by avoiding frame(s) and/or sub-frame(s) indicated by neighboring cells ))Wait. In other examples, the transmission periodicity may be based on the payload size of the xSIB indicated by the xMIB (for example, via a predefined association in the specification, etc.).

The processor(s) 910 may generate an xSIB, as described in more detail herein. The processor(s) 910 can generate a set of bits, which can contain data for xSIB, and can apply coding (such as CRC before TBCC, turbo code, LDPC, etc.) to the generated bits to obtain a set The xSIB bit has been written. In the aspect, the type of coding applied may depend on the size of the xSIB payload.

The processor(s) 910 may stir the set of coded xSIB bits to obtain a set of stirred xSIB bits, which may be based on a stirring sequence initiated by a stirring seed, which may depend on the physical cell. One or more of meta ID, subframe index, time slot index, or OFDM symbol index.

The processor(s) 910 may modulate the set of stirred xSIB bits based on a modulation type to obtain a set of modulated xSIB symbols. The modulation type may be a type with a low modulation order (for example, BPSK, QPSK, etc.), which can ensure stable xSIB transmission.

The processor(s) 910 may map the group of modulated xSIB symbols to a frequency domain resource set, which may be shared with a physical xSIB channel (for example, a dedicated channel for xSIB, a 5G physical downlink shared channel ( xPDSCH) etc.). Frequency domain resources can be selected based at least in part on the payload size of xSIB, and can be changed based on the embodiment. For example, for a large xSIB block, the frequency domain resources may include a full system bandwidth. For another example, for a small xSIB block, the frequency domain resource may include a part of the system bandwidth (for example, 1/N of a full system bandwidth, for example, for N=3, etc.), and this system bandwidth The other part can be used to reduce inter-cell interference by neighboring cells. In some examples, when the xSIB block is less than a full system bandwidth or the system bandwidth is used by a cell to reduce a part of the inter-cell interference, multiple copies of the bandwidth xSIB block can be allocated across the bandwidth , Each of which can be associated with a different BRS antenna port (AP).

The processor(s) 910 may output the physical xSIB channel to the transceiver circuitry 920 for transmission during a selected sub-frame. Depending on the type of signal or message generated, the output for transmission (by processor(s) 910, processor(s) 1010, etc.) may include one or more actions such as those discussed above with xSIB , Such as generating an indication signal or a set of associated bits of the message content, writing code (for example, it may include the newly added cyclic redundancy check (CRC), and/or through turbo code, low-density parity check (LDPC) code, tail l Code elimination convolutional code writer (TBCC), one or more of them perform code writing, etc.), stirring (for example based on a stirring seed), modulation (for example, via binary phase shift keying (BPSK), quaternary phase shift Keying (QPSK), or a form of Quadrature Amplitude Modulation (QAM), etc.), and/or resource mapping (for example, mapping to a set of scheduled resources, mapping to granting a set of uplink transmission Time and frequency resources, etc.).

The processor(s) 910 may output a physical xSIB channel for each of the plurality of OFDM symbols of the selected subframe for xSIB transmission for the transceiver circuitry 920 to transmit via one or more distinct Tx beams. For larger xSIB blocks, or in some frequency-based inter-cell interference mitigation scenarios involving smaller xSIB blocks, a single Tx beam can be used for each OFDM symbol through the full system bandwidth (for larger xSIB block), or the whole part of the system bandwidth used by the cell (for some smaller xSIB blocks that reduce inter-cell interference based on different frequency resources) to transmit xSIB. For other aspects involving smaller xSIB blocks, multiple distinct Tx beams can be applied to each OFDM symbol, and frequency domain resources can be assigned between those Tx beams based on a localized or distributed strategy, such as Figure 4 The examples are shown. In the aspect, one or more Tx beams selected for each OFDM symbol transmission xSIB block can be based on the xSIB and Tx used to transmit one or more of the synchronization signal, beam reference signal (BRS), xPBCH, etc. A predefined association or mapping relationship between beams can facilitate xSIB block selection by the UE.

In addition, the physical xSIB channel can be transmitted via an xSIB block including a set of DM-RS. The group of DM-RS can be arranged based on a predetermined pattern, which can depend on the number of REs for each xSIB block and/or the number of APs for xSIB transmission. Figures 5 to 7 provide exemplary patterns for specific values of RE and AP. For multiple APs, multiplexing can be based on frequency domain multiplexing (FDM) or code division multiplexing (CDM). For SFBC applied with xSIB transmission, consecutive RE pairs can be used for xSIB transmission.

In some aspects, xSIB transmission can be based on one or more techniques to mitigate inter-cell interference. In various embodiments, different time domain resources and/or frequency domain resources can be used by various cells to reduce interference.

In various aspects related to interference mitigation based on different time-domain resources, the cell may transmit xSIB during frame(s) and/or sub-frame(s), which may depend on the physical cell ID. For example, the cells can be divided into N groups based on the physical cell ID (for example, N=3, etc.), and each group is associated with a different frame and/or sub-frame for xSIB transmission. For example, based on the remainder after dividing the entity cell ID by N, or some other function based on the entity cell ID, the cells can be assigned to the dissimilar groups. In some aspects, as discussed herein, the frame(s) and/or sub-frame(s) can be indicated through a field included in the xMIB.

In various aspects based on the combination of different frequency domain resources and interference mitigation, the full system bandwidth can be divided into N (for example, 3, etc.) different parts, and the cells can be divided into N groups, each The group is associated with one of these N different parts. For example, based on the remainder after dividing the entity cell ID by N, or some other function based on the entity cell ID, a cell can be specified for a different part.
