In the following description, transmit path 200 can be described as being implemented in a gNB (such as gNB 102), while receive path 250 can be described as being implemented in a UE (such as UE 116). However, it should be understood that receive path 250 can be implemented in a gNB, and transmit path 200 can be implemented in a UE. In some embodiments, receive path 250 is configured to support codebook design and structure for a system having a 2D antenna array as described in embodiments of this disclosure.

[0156] The transmit path 200 includes a channel coding and modulation block 205, a serial-to-parallel (S-to-P) block 210, an N-point inverse fast Fourier transform (IFFT) block 215, a parallel-to-serial (P-to-S) block 220, a cyclic prefix addition block 225, and an up-converter (UC) 230. The receive path 250 includes a down-converter (DC) 255, a cyclic prefix removal block 260, a serial-to-parallel (S-to-P) block 265, an N-point fast Fourier transform (FFT) block 270, a parallel-to-serial (P-to-S) block 275, and a channel decoding and demodulation block 280.

[0157] In transmit path 200, channel coding and modulation block 205 receives a set of information bits, applies coding (such as low-density parity-check (LDPC) coding), and modulates the input bits (such as using quadrature phase shift keying (QPSK) or quadrature amplitude modulation (QAM)) to generate a sequence of frequency-domain modulated symbols. Serial-to-parallel (S-to-P) block 210 converts (e.g., demultiplexes) the serial modulated symbols into parallel data to generate N parallel symbol streams, where N is the number of IFFT / FFT points used in gNB 102 and UE 116. N-point IFFT block 215 performs IFFT operations on the N parallel symbol streams to generate a time-domain output signal. Parallel-to-serial block 220 converts (e.g., multiplexes) the parallel time-domain output symbols from N-point IFFT block 215 to generate a serial time-domain signal. Cyclic prefix addition block 225 inserts a cyclic prefix into the time-domain signal. Upconverter 230 modulates (e.g., upconverts) the output of the added cyclic prefix block 225 to an RF frequency for transmission via a wireless channel. The signal can also be filtered at the baseband before being converted to the RF frequency.

[0158] The RF signal transmitted from gNB 102 reaches UE 116 after passing through the wireless channel, and UE 116 performs the opposite operation to that at gNB 102. Downconverter 255 downconverts the received signal to the baseband frequency, and cyclic prefix removal block 260 removes the cyclic prefix to generate a serial time-domain baseband signal. Serial-to-parallel block 265 converts the time-domain baseband signal into a parallel time-domain signal. N-point FFT block 270 performs an FFT algorithm to generate N parallel frequency-domain signals. Parallel-to-serial block 275 converts the parallel frequency-domain signals into a sequence of modulated data symbols. Channel decoding and demodulation block 280 demodulates and decodes the modulated symbols to recover the original input data stream.

[0159] Each of gNBs 101-103 can implement a transmission path 200 similar to that used for transmission to UEs 111-116 in the downlink, and a reception path 250 similar to that used for reception from UEs 111-116 in the uplink. Similarly, each of UEs 111-116 can implement a transmission path 200 for transmission to gNBs 101-103 in the uplink, and a reception path 250 for reception from gNBs 101-103 in the downlink.

[0160] Figure 2a and Figure 2b Each of the components can be implemented using only hardware, or using a combination of hardware and software / firmware. As a specific example, Figure 2a and Figure 2b At least some of the components can be implemented in software, while others can be implemented in configurable hardware or a combination of software and configurable hardware. For example, FFT block 270 and IFFT block 215 can be implemented as configurable software algorithms, wherein the value of the number of points N can be modified according to the implementation method.

[0161] Furthermore, although the description uses FFT and IFFT, this is merely illustrative and should not be construed as limiting the scope of this disclosure. Other types of transforms, such as the Discrete Fourier Transform (DFT) and Inverse Discrete Fourier Transform (IDFT) functions, can be used. It should be understood that for DFT and IDFT functions, the value of variable N can be any integer (such as 1, 2, 3, 4, etc.), while for FFT and IFFT functions, the value of variable N can be any integer that is a power of 2 (such as 1, 2, 4, 8, 16, etc.).

[0162] although Figure 2a and Figure 2b An example of a wireless transmit and receive path is shown, but it is possible to modify it further. Figure 2a and Figure 2b Make various changes. For example, Figure 2a and Figure 2b The various components can be combined, further subdivided, or omitted, and additional components can be added as needed. Furthermore, Figure 2a and Figure 2b This is intended to illustrate examples of the types of send and receive paths that can be used in a wireless network. Any other suitable architecture can be used to support wireless communication in a wireless network.

[0163] Figure 3a Example UE 116 according to this disclosure is shown. Figure 3a The embodiment of UE 116 shown is for illustrative purposes only, and Figure 1UEs 111-115 can have the same or similar configurations. However, UEs have a wide variety of configurations, and Figure 3a This disclosure is not intended to limit the scope of any particular implementation of the UE.

[0164] UE 116 includes an antenna 301, a radio frequency (RF) transceiver 302, a transmit (TX) processing circuitry 303, a microphone 304, and a receive (RX) processing circuitry 305. UE 116 also includes a speaker 306, a controller / processor 307, an input / output (I / O) interface (IF) 308, multiple input devices 309, a display 310, and a memory 311.

[0165] RF transceiver 302 receives incoming RF signals transmitted by a gNB of wireless network 100 from antenna 301. RF transceiver 302 down-converts the incoming RF signals to generate an intermediate frequency (IF) or baseband signal. The IF or baseband signal is sent to RX processing circuitry 305, which generates a processed baseband signal by filtering, decoding, and / or digitizing the baseband or IF signal. RX processing circuitry 305 sends the processed baseband signal to speaker 306 (e.g., for voice data) or to controller / processor 307 (e.g., for web browsing data) for further processing.

[0166] TX processing circuitry 303 receives analog or digital voice data from microphone 304, or other outgoing baseband data (such as network data, email, or interactive video game data) from controller / processor 307. TX processing circuitry 303 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate processed baseband or IF signals. RF transceiver 302 receives the processed baseband or IF signals from TX processing circuitry 303 and up-converts the baseband or IF signals into RF signals transmitted via antenna 301.

[0167] The controller / processor 307 may include one or more processors or other processing devices and execute an OS 312 stored in memory 311 to control the overall operation of the UE 116. For example, the controller / processor 307 may control the reception of forward channel signals and the transmission of reverse channel signals through the RF transceiver 302, the RX processing circuit 305, and the TX processing circuit 303 according to known principles. In some embodiments, the controller / processor 307 includes at least one microprocessor or microcontroller.

[0168] The controller / processor 307 is also capable of executing other processes and programs residing in the memory 311, such as operations for channel quality measurement and reporting for a system having a 2D antenna array as described in the embodiments of this disclosure. The controller / processor 307 is capable of moving data into or out of the memory 311 as needed for the execution of the process. In some embodiments, the controller / processor 307 is configured to execute an application 313 based on the OS 312 or in response to signals received from a gNB or operator. The controller / processor 307 is also coupled to an I / O interface 308, which provides the UE 116 with the ability to connect to other devices such as laptop computers and handheld computers. The I / O interface 308 is the communication path between these accessories and the controller / processor 307.

[0169] The controller / processor 307 is also coupled to input devices(s) 309 and a display 310. An operator of the UE 116 can use the input devices(s) 309 to input data into the UE 116. The display 310 may be a liquid crystal display or another display capable of displaying text and / or at least limited graphics (such as from a website). Memory 311 is coupled to the controller / processor 307. A portion of memory 311 may include random access memory (RAM), while another portion of memory 311 may include flash memory or other read-only memory (ROM).

[0170] although Figure 3a An example of UE 116 is shown, but it is possible to... Figure 3a Make various changes. For example, Figure 3a The various components can be combined, further subdivided, or omitted, and additional components can be added as needed. As a specific example, the controller / processor 307 can be divided into multiple processors, such as one or more central processing units (CPUs) and one or more graphics processing units (GPUs). Furthermore, although... Figure 3a The UE116 is shown configured as a mobile phone or smartphone, but the UE can be configured to operate as other types of mobile or fixed devices.

[0171] Figure 3b An example gNB 102 according to this disclosure is shown. Figure 3b The embodiment of gNB 102 shown is for illustrative purposes only, and Figure 1 Other gNBs can have the same or similar configurations. However, gNBs have a wide variety of configurations, and Figure 3b The scope of this disclosure is not limited to any particular implementation of the gNB. It should be noted that gNB 101 and gNB 103 can include the same or similar structures as gNB 102.

[0172] like Figure 3b As shown, gNB 102 includes multiple antennas 370a-370n, multiple RF transceivers 372a-372n, transmit (TX) processing circuitry 374, and receive (RX) processing circuitry 376. In some embodiments, one or more of the multiple antennas 370a-370n include a 2D antenna array. gNB 102 also includes a controller / processor 378, a memory 380, and a backhaul or network interface 382.

[0173] RF transceivers 372a-372n receive incoming RF signals, such as signals transmitted by the UE or other gNBs, from antennas 370a-370n. RF transceivers 372a-372n down-convert the incoming RF signals to generate IF or baseband signals. The IF or baseband signals are sent to RX processing circuitry 376, which generates processed baseband signals by filtering, decoding, and / or digitizing the baseband or IF signals. RX processing circuitry 376 sends the processed baseband signals to controller / processor 378 for further processing.

[0174] The TX processing circuit 374 receives analog or digital data (such as voice data, network data, email, or interactive video game data) from the controller / processor 378. The TX processing circuit 374 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. RF transceivers 372a-372n receive the outgoing processed baseband or IF signal from the TX processing circuit 374 and up-convert the baseband or IF signal into an RF signal transmitted via antennas 370a-370n.

[0175] The controller / processor 378 may include one or more processors or other processing devices that control the overall operation of the gNB 102. For example, the controller / processor 378 may control the reception of forward channel signals and the transmission of reverse channel signals via RF transceivers 372a-372n, RX processing circuitry 376, and TX processing circuitry 374, according to known principles. The controller / processor 378 may also support additional functions, such as more advanced wireless communication functions. For example, the controller / processor 378 may perform a BIS process, such as by a blind interference sensing (BIS) algorithm, and decode the received signal after subtracting interference. The controller / processor 378 may support any of a wide variety of other functions in the gNB 102. In some embodiments, the controller / processor 378 includes at least one microprocessor or microcontroller.

[0176] The controller / processor 378 is also capable of executing programs and other processes, such as a basic operating system, residing in the memory 380. The controller / processor 378 is also capable of supporting channel quality measurement and reporting for systems having 2D antenna arrays as described in embodiments of this disclosure. In some embodiments, the controller / processor 378 supports communication between entities such as web RTCs. The controller / processor 378 is capable of moving data into or out of the memory 380 as needed for the execution of processes.

[0177] The controller / processor 378 is also coupled to a backhaul or network interface 382. The backhaul or network interface 382 allows the gNB 102 to communicate with other devices or systems via a backhaul connection or over a network. The backhaul or network interface 382 is capable of supporting communication via any suitable wired or wireless connection(s). For example, when the gNB 102 is implemented as part of a cellular communication system (such as a cellular communication system supporting 5G or new radio access technologies or NR, LTE, or LTE-A), the backhaul or network interface 382 allows the gNB 102 to communicate with other gNBs via a wired or wireless backhaul connection. When the gNB 102 is implemented as an access point, the backhaul or network interface 382 allows the gNB 102 to communicate with a larger network (such as the Internet) via a wired or wireless local area network or via a wired or wireless connection. The backhaul or network interface 382 includes any suitable architecture supporting communication via a wired or wireless connection, such as an Ethernet or RF transceiver.

[0178] Memory 380 is coupled to controller / processor 378. A portion of memory 380 may include RAM, while another portion may include flash memory or other ROM. In some embodiments, multiple instructions, such as a BIS algorithm, are stored in memory. The multiple instructions are configured to cause controller / processor 378 to perform the BIS process and decode the received signal after subtracting at least one interference signal determined by the BIS algorithm.

[0179] As described in more detail below, the transmit and receive paths of the gNB 102 (implemented using RF transceivers 372a-372n, TX processing circuitry 374, and / or RX processing circuitry 376) support aggregated communication with FDD and TDD cells.

[0180] although Figure 3b An example of gNB 102 is shown, but more can be found on... Figure 3b Various modifications can be made. For example, gNB102 can include any number of... Figure 3aEach component shown. As a specific example, an access point can include multiple backhaul or network interfaces 382, ​​and a controller / processor 378 can support routing functions to route data between different network addresses. As another specific example, although shown as a single instance including TX processing circuitry 374 and a single instance including RX processing circuitry 376, the gNB 102 can include multiple instances of each (such as one for each RF transceiver).

[0181] With the continuous development of wireless communication systems, in order to achieve higher data rates, networks need to use more antennas, larger bandwidths, and more frequency bands, making high energy consumption a growing problem for operators. Meanwhile, in communication systems, the primary synchronization signals (PSS), secondary synchronization signals (SSS), and the physical broadcast channel (PBCH) together form synchronization signal blocks (SSBs), primarily used for downlink synchronization and measurement. Each SSB appears several times within a half-frame at regular intervals, forming a set of SSBs. The period of the SSB set can be, for example, 5ms, 10ms, 20ms, 40ms, 80ms, or 160ms. However, periodically transmitting these SSBs consumes significant time-frequency resources and depletes network energy. Conversely, completely refraining from transmitting SSBs makes it difficult to guarantee time and frequency synchronization, thus impacting the overall performance of the communication system. Therefore, there is an urgent need for an enhanced on-demand SSB-based communication method to achieve energy-efficient and high-performance communication for the entire communication system.

[0182] For ease of description, this disclosure refers to the periodically transmitted synchronization signal block SSB as always-on SSB, and the on-demand synchronization signal block SSB introduced for network energy saving as on-demand SSB. As shown in the figure below, when the user equipment receives an on-demand SSB sent by the network device, there may be no always-on SSB available to receive. Figure 4a In this scenario, network devices save energy because they no longer need to send always-on SSBs. It's also possible that always-on SSBs can still be received ( Figure 4bIn this scenario, network devices save energy by sending longer-cycle always-on SSB signals. Regardless of whether it's an on-demand SSB-only scenario or a scenario where on-demand SSB and always-on SSB coexist, the user equipment needs to be able to receive on-demand SSB signals, perform measurements according to the corresponding measurement requirements based on on-demand SSB and / or always-on SSB signals, and report the relevant measurement results. It also needs to activate the SCell according to the corresponding activation delay requirements based on on-demand SSB and / or always-on SSB signals in order to maintain the energy-efficient operation of the communication system.

[0183] Exemplary embodiments of this disclosure are further described below with reference to the accompanying drawings.

[0184] The text and accompanying drawings are provided by way of example only to aid the reader in understanding this disclosure. They are not intended and should not be construed as limiting the scope of this disclosure in any way. Although certain embodiments and examples have been provided, it will be apparent to those skilled in the art, based on the content disclosed herein, that changes may be made to the illustrated embodiments and examples without departing from the scope of this disclosure.

[0185] Figure 5 A flowchart illustrating a method performed by a user equipment in a communication system according to an embodiment of this disclosure is shown. It can be understood that...

[0395] Invention Point 3: Criteria for Judging Known Cells

[0396] On-demand SSB typically occurs in short-duration, intensive forms. During the duration of an on-demand SSB, an always-on SSB may or may not exist. For user equipment supporting on-demand SSB, an FR1SCell is a known cell if it meets the following conditions:

[0397] - For FR1, the time interval before the user equipment receives the SCell activation command is max(5*SMTC) new ,5*DRXcycles) or max(T duration ,5*DRX cycles) or max(5*measCycleSCell,5*DRX cycles):

[0398] - The user equipment sends a valid measurement report to the SCell to be activated, and

[0399] - Based on existing cell identification conditions, on-demand SSB and / or always-on SSB measurements are still detectable.

[0400] - Based on existing cell identification conditions, the maximum time interval of the SCell activation delay of the user equipment is (5*SMTC). new ,5*DRX cycles) or max(T duration Within 5*DRX cycles or max(5*measCycleSCell, 5*DRXcycles), on-demand SSB and / or always-on SSB measurements remain detectable.

[0401] or,

[0402] -The user equipment has received a sufficient number of SSBs, not less than N.

[0403] -N can be the number of on-demand SSBs, or

[0404] -N can be the sum of the number of on-demand SSBs and always-on SSBs.

[0405] Otherwise, FR1SCell is an unknown cell.

[0406] The values ​​of each parameter are the same as above.

[0407] Among them, the time interval max(5*SMTC) new ,5*DRX cycles) or max(T duration The fourteenth duration can be represented by either 5*DRX cycles or max(5*measCycleSCell,5*DRX cycles).

[0408] For the first SCell activation of FR2bands, an FR2SCell that satisfies the following condition is a known cell:

[0409] - Within a time interval of 4 seconds (when the user equipment supports power class 1 / 5) and 3 seconds (when the user equipment supports power class 2 / 3 / 4) before the user equipment receives the last activation command of the semi-persistent CSI-RS reported by PDCCH TCI, PDSCH TCI and CQI:

[0410] - The user equipment has sent a valid L3-RSRP measurement report carrying on-demand SSB and / or always-on SSB indexes, and

[0411] - The user equipment receives the SCell activation command after reporting to L3-RSRP, and no later than the time when the user equipment receives the MAC-CE command for TCI activation.

[0412] - Within the time interval from L3-RSRP reporting to valid CQI reporting, according to existing cell identification conditions, reported on-demand SSBs and / or always-on SSBs carrying indexes can still be detected, and the TCI state is selected based on the latest reported SSB index. Or

[0414] -N can be the number of on-demand SSBs, or

[0415] -N can be the sum of the number of on-demand SSBs and always-on SSBs.

[0416] Otherwise, the SCell on FR2bands is an unknown cell.

[0417] The values ​​of each parameter are the same as above.

[0418] Among them, the time intervals of 4 seconds (when the user equipment supports power class 1 / 5) and 3 seconds (when the user equipment supports power class 2 / 3 / 4) correspond to the fifteenth duration mentioned above.

[0419] Introducing new criteria for determining known cells helps user equipment to quickly and easily determine cell status, thereby improving the overall efficiency of the communication system.

[0420] Example 4: Cell Measurements Using Intra-frequency and Inter-frequency

[0421] Before the introduction of on-demand SSB, user equipment measurements based on SSB were performed using always-on SSB. Because always-on SSB is periodic, the detection time of PSS / SSS and the measurement time of RSRP / RSRQ / SINR based on SSB were typically related to the SSB period. With the introduction of on-demand SSB, this periodicity will be broken. On-demand SSB may only exist for a period of time, and always-on SSB may exist or may not exist. Therefore, the user equipment's detection time of PSS / SSS and the measurement time of SS-RSRP / SS-RSRQ / SS-SINR / L1-RSRP need to be adjusted accordingly to maintain the normal operation of the entire communication system.

[0422] When the user equipment receives the on-demand SSB signal, the user equipment should be able to... identify_intra_without_index / T identify_inter_without_index or T identify_intra_with_index / T identify_inter_with_index A new detectable intra-frequency / inter-frequency cell was identified within the time period T. identify_intra_without_index / T identify_inter_without_index or T identify_intra_with_index / T identify_inter_with_index Detection time T of PSS / SSS PSS / SSS_sync_intra / T PSS / SSS_sync_inter The measurement duration T of SSB SSB_measurement_period_intra / T SSB_measurement_period_inter and the duration T for obtaining the measured SSB index SSB_time_index_intra / T SSB_time_index_inter related.

[0423] After the user equipment receives the on-demand SSB signal, the user equipment's measurements of SS-RSRP / SS-RSRQ / SS-SINR / L1-RSRP must also meet the measurement duration T. SSB_measurement_period_intra / T SSB_measurement_period_inter and T L1-RSRP_Measurement_SSB .

[0424] When the user equipment supports the aforementioned first capability, T identify_intra_without_index / T identify_inter_without_index or T identify_intra_with_index / T identify_inter_with_index And T L1-RSRP_Measurement_SSB The time required to define the on-demand SSB is necessary to ensure the effective operation of the communication system.

In this case, the corresponding detection and / or measurement duration can be defined as max(Y1ms, T...). duration )*CSSF intra Or, T duration *CSSF intra .

[0464] When the user device supports the second capability: not only T duration The on-demand SSB signal within can be used for corresponding detection and / or measurement, T duration The always-on SSB signal within can also be used for corresponding detection and / or measurement.

[0465] In addition, to ensure the accuracy of the measurements for the above three schemes, some other embodiments of this disclosure also define user equipment behavior guidelines when the number of measurement samples is insufficient or the measurement time is insufficient:

[0466] -When the user equipment supports the first capability:

[0467] - If the number of on-demand SSB occasions within the measurement window is less than Z1, the user equipment may either measure according to the actual number of on-demand SSB occasions or discard the measurement window.

[0468] -If T duration If, within a given time period, the number of on-demand SSBs received by the user equipment is less than M1 (which corresponds to the seventh value mentioned above), the user equipment may either measure according to the actual number of on-demand SSBs or discard this measurement window. M1 is a predefined value, such as 10, 15, etc.

[0469] -If Z1*SMTC new +(Z1-1)*T gap Or Z1*T2 SSB +(Z1-1)*T gap Or T duration If the time is less than Y1ms, then the detection time of PSS / SSS or the time to obtain the index of the measured SSB can be calculated according to T. duration This measurement window can be defined or discarded, where T gap It can be the interval between multiple on-demand SSBs.

[0470] In this embodiment, press T duration This can be understood as defining T as the detection time of PSS / SSS or the time to obtain the index of the measured SSB. duration Alternatively, the detection duration of PSS / SSS or the duration of obtaining the index of the measured SSB can be determined based on the implementation method of Scheme 3 in Embodiment 4 above.

[0471] -When the user device supports the second capability:

[0472] - In addition to the on-demand SSB, the signals used for detection or measurement may also include the always-on SSB signal within the measurement window, which also follows the detection or measurement criteria described above.

[0473] Furthermore, regarding the processing of measurement results, if the user equipment supports the second capability, and the measurement results of SS-RSRP / SS-RSRQ / SS-SINR / L1-RSRP include not only on-demand SSB measurements but also always-on SSB measurements, when the user equipment performs operations such as linear averaging, taking the maximum value, taking the minimum value, and taking the arithmetic average of the results, the two types of results must first be normalized by power before the operation. The power value can be obtained from the configuration information of on-demand SSB and / or always-on SSB, or calculated based on the configuration information of on-demand SSB and / or always-on SSB.

[0474] Example 5: SCell Activation / Deactivation Interruption Requirement

[0476]

[0477]

[0478] Table 4

[0479] Example 6: SSB Usage Priority Criteria

[0480] When a user equipment receives both an on-demand SSB signal from the SCell to be activated and an always-on SSB signal from the SCell to be activated, one or more of the following usage guidelines for SSB signals can be introduced:

[0481] Rule 1: Only use on-demand SSB;

[0482] Rule 2: Use only always-on SSB;

[0483] Guideline 3: Use on-demand SSB and always-on SSB in combination;

[0484] Rule 4: Always-on SSB and on-demand SSB are considered to be two valid SSBs if they are separated by Q symbols, for example: Q = 4, where Q can correspond to the first quantity mentioned above.

[0485] Alternatively, define new user device behavior constraints:

[0486] - User equipment does not expect to receive always-on SSB and on-demand signals in the same time unit.

[0487] SSB. Or,

[0488] - The user equipment receives an on-demand SSB signal, where the on-demand SSB does not expect to be...

[0489] Always-on SSBs are transmitted within the same time unit.

[0490] It should be understood that a time unit can be a symbol, a time slot, a mini time slot, a subframe, a half-frame, a frame, etc., and this embodiment does not limit it.
