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

Additionally, while the above illustrative discussion of device 100 is in the context of a UE device, in various aspects, a similar device can be utilized in conjunction with a base station (BS) such as an evolved Node B (eNB).

While 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 introduces additional complications. For example, in the case of applying a Tx beam sweep to an xPDCCH (5G (Fifth Generation) Physical Downlink Control Channel) with a common search space, it is possible to increase the system's extra load and thereby reduce the spectral efficiency of repeated transmissions. May be appropriate. In order to reduce system extra load, the 5G System Information Sector (xSIB) may consider no xPDCCH operation. In such cases, the schedule of xSIB transmissions 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 is observed. To reduce this inter-cell interference and improve decoding performance with respect to xSIB transmission, a mechanism for coordinating xSIB transmissions between multiple cells, such as those described herein, may be employed.

Various embodiments may utilize the techniques discussed herein with respect to the xSIB design details of the 5G system. In various aspects, these techniques may include details associated with the (multiple) transmission strategy used by xSIB, and/or the mechanism(s) that may reduce inter-cell interference for xSIB transmission.

In each aspect, the payload size of xSIB transmissions can vary from case to case and deployment scenario. Therefore, the UE side may have information about the size of the payload to ensure that the demodulation and decoding are appropriate.

In some aspects, the xSIB transmission has N possible payload sizes (eg, N = 4, or larger or smaller numbers). The xMIB (5G Master Information Section) may include a field that can be used to indicate which payload size to use 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, the xMIB transmission periodicity can also be indicated in the xMIB. For example, a field containing one or more bits can be used to indicate the xSIB transmission periodicity (eg, bit 0 can indicate that the xSIB transmission period is 80 ms, and bit 1 indicates that the xSIB transmission period is 160 ms, etc.) ).

Alternatively, the xSIB transmission periodicity may be associated with a x1:1 of 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 signaling overhead in xMIB.

In some embodiments, the xSIB resource mapping is determined by the payload size. 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 can occupy a portion of the system frequency. Wide (for example, as shown in Figure 4, discussed below).

Referring to Figure 2, there is shown an exemplary method 200 for generating an xSIB in accordance with various aspects described herein. A detailed design of this xSIB can be as follows.

At 210, a write code can be applied to the xSIB information bit (eg, it can include X bits, where X is any positive integer, such as one of the values that can be indicated via a corresponding field in the xMIB). In one example, a tail code deconvolution codec (TBCC) can be applied to the xSIB. In the aspect, a CRC (Cyclic Redundancy Check) can be appended to the xSIB information bit before encoding. In other examples, turbo code or LDPC (low density parity check) is available for xSIB information bits instead of TBCC.

At 220, after writing the code, a particular cell can be scrambled to further randomize the interference. In an aspect, the agitation seed can be defined as one of one or more of a physical cell ID, a sub-frame index, a time slot index, or a symbol index for xSIB transmission. In one example, the agitated seed can be obtained by Equation 1: (1), Where n _s is the time slot index and l is the OFDM (orthogonal frequency division multiplexing) symbol index, and Is the entity cell ID.

At 230, a modulation type having a low-key order (eg, 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 allocated resources, wherein the resource mapping mechanism can be as described below.

To allow for Tx (transmit) beam sniffering of xSIB transmissions, one xSIB transmission may span 1 or more OFDM symbols. Depending on the size of the payload, the 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, the xSIB transmission occupies a full system bandwidth. Additionally, different Tx beams can be applied across each OFDM symbol to ensure good cell coverage. Referring to FIG. 3, according to various aspects described herein, an example is shown in which the Tx beam sweeps when the xSIB occupies a full system bandwidth. Note that in the example of Figure 3, the same xSIB information bits are transmitted in each OFDM symbol, but by different Tx beams.

In embodiments where the xSIB occupies part of the system bandwidth, a localized or decentralized transmission strategy can be employed. The number of xSIBs in a symbol can be determined by the number of BRS (Beam Reference Signal) antennas. The Tx beams of each xSIB block may be mapped one-to-one to the Tx beam applied to the BRS. Referring to FIG. 4, according to various aspects described herein, an example of performing Tx beam snagging on an xSIB occupying part of the system bandwidth via localized or decentralized resource allocation is illustrated. The example shown in Figure 4 shows four Tx beams per symbol, and a total of 56 beams can be applied to the BRS in a sub-frame. These 56 Tx beam sweeps can be applied to the xSIB subframe. In various aspects, the Tx beam mapping rules between xSIB and BRS can be predefined by specifications such that the UE can select the best xSIB block(s) to be decoded. This (etc.) xSIB block is available for the highest BRS-RP taken from the associated Tx beam.

Depending on the number of resource elements (REs) allocated for each xSIB block and the number of APs (antennas) for xSIB transmission, the following different options are available for DM-RS (demodulation variable reference signal).

Referring to FIG. 5, according to various aspects described herein, an example of a DM-RS pattern for 單埠 transmission occupying 8 REs at xSIB is illustrated. Referring to FIG. 6, according to various aspects described herein, an example is shown in which the DM-RS pattern for 單埠 transmission has 12 REs in the xSIB. Please note that a similar pattern can be defined for the dual-xXBB transmission. As shown in FIG. 7, an exemplary representation of the xSIB for two APs occupying 12 REs in the xSIB is illustrated according to the aspects described herein. DM-RS type. In each aspect, the DM-RSs for the two APs can be multiplexed according to a frequency division multiplexing (FDM) or a code division multiplexing (CDM) manner.

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 Write Code) is applied to the xSIB transmission, two sequential REs can be used for xSIB transmission.

In various aspects, in order to minimize the power consumption of the UE, a 1:1 Tx beam mapping relationship between the synchronization signal/beam reference signal (BRS)/xPBCH and the xSIB may be defined. In such an aspect, a UE can listen to only one symbol for xSIB decoding. Referring to FIG. 8, an example of a 1:1 Tx beam mapping relationship between xPBCH and xSIB transmission is illustrated according to the aspects described herein. In an example, if a UE successfully decodes the xPBCH on symbol #3 in Tx beam group #1, the same (multiple) Rx beams can be used to decode the symbol #3 on the corresponding xSIB subframe. xSIB.

The various aspects described herein may also facilitate mitigating inter-cell interference associated with xSIB transmission. One or more of the following techniques can be used to mitigate inter-cell interference on (multiple) xSIB transmissions.

In some aspects, different cells can transmit xSIB in different frames and subframes (SF). In an example, 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 may be employed in a similar manner.

In other aspects, different cells can transmit xSIB in the same subframe, but transmit in different frequency resources. This technique applies to small xSIB payload sizes. In one example, the system bandwidth can be divided into N blocks (eg, N=3, or larger or smaller numbers), which can be dispersed or localized in the frequency domain. Depending on the physical cell ID, different cells may transmit xSIB in different blocks, which may establish a reuse-N transmission pattern.

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

In a further aspect, one of the fields in the xMIB can be used to indicate a frame and/or subframe index for transmitting the xSIB. A group frame and/or sub-frame for transmitting xSIB can be predefined in the specification. This bit field in the xMIB can be used to indicate which frame and/or subframe for the xSIB transmission. Table 3 below illustrates an example of a bit column indication in xMIB that provides four example values (in each case, more or fewer values are available). In this example, the xSIB can be transmitted in one of the two frames, or can be transmitted within 20 ms. Note that other examples can be extended directly from the examples listed below.

Referring to FIG. 9, according to the aspects described herein, it is shown that a base station is generated to generate a fifth generation (5G) system information section (xSIB) for transmission to one or more user equipments ( A block diagram of one of the systems 900 of the UE. System 900 can include one or more processors 910 (eg, one or more baseband processors, such as one or more of the baseband processors discussed with respect to FIG. 1), transceiver circuitry 920 (eg, which includes transmissions One or more of a circuit system (eg, associated with one or more transmission chains) or a receiver circuit system (eg, associated with one or more receive chains), wherein the transmitter circuitry and the receiver circuitry are operational Common circuit elements, distinct circuit elements, or a combination thereof, and memory 930 (which may include any of a variety of storage media, and may be stored in association with one or more processors 910 or transceiver circuitry 920) Instructions and / or information).

In some aspects, processor(s) 910, transceiver circuitry 920, and memory 930 can be included in a single device, and in other aspects, can be included in different devices, such as included in Part of a decentralized architecture. As explained in greater detail below, system 900 can facilitate generating an xSIB for subsequent transmission to a plurality of UEs via a plurality of distinct transmit (Tx) beams.

In various aspects, processor(s) 910 can generate a 5G master information segment (xMIB) and can output xMIB to transceiver circuitry 220 for use (eg, via a 5G physical broadcast channel (xPBCH)) And so on) to one or more UEs. The processor(s) 910 can generate an xMIB to indicate one or more parameters of the xSIB. For example, the xMIB may indicate one of the xSIB sizes, such as via one of the xSIB payload sizes, one of the xSIB transmission durations, and the like. In another example, the xMIB may indicate one or more parameters associated with the timing of the (multiple) transmissions of the xSIB, such as the transmission periodicity of the xSIB, the frame(s), and/or the message(s). Block (the xSIB will be transmitted during this period (which may be selected to minimize inter-cell interference by avoiding the frame(s) and/or subframe(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 (eg, via a predefined association in the specification, etc.).

The processor(s) 910 can generate an xSIB as described in more detail herein. The processor(s) 910 can generate a set of bits that can contain data for the xSIB and can apply a write code (eg, CRC before the TBCC, turbo code, LDPC, etc.) to the set of generated bits to obtain a set of bits.
