Description
Information processing methods and apparatus, communication equipment and storage media
[0001] This disclosure is a divisional application of Chinese application filed on January 20, 2022, with application number 202280000219.4 and title "Information Processing Method and Apparatus, Communication Equipment and Storage Medium". Technical Field
[0002] This disclosure relates to, but is not limited to, the field of wireless communication technology, and particularly to an information processing method and apparatus, communication equipment and storage medium. Background Technology
[0003] With technological advancements, various terminals supporting different bandwidths have emerged. For example, in the Long Term Evolution (LTE) 4G mobile communication system, two major technologies were proposed to support Internet of Things (IoT) services: Machine Type Communication (MTC) and Narrow Band Internet of Things (NB-IoT). These two technologies primarily target scenarios with low data rates and high latency, such as meter reading and / or environmental monitoring.
[0004] Currently, NB-IoT can only support speeds of a few hundred kilobytes per second (Mbps), while MTC can only support speeds of a few megabytes per second (Mbps). However, with the continuous development of IoT services, such as video surveillance, smart homes, wearable devices, and industrial sensing and monitoring, these services typically require speeds of tens to 100 megabytes per second (Mbps) and relatively high latency. Therefore, LTE's MTC and NB-IoT technologies struggle to meet these requirements. Based on this situation, a new type of user equipment (UE) has been introduced in 5G New Radio (NR) to cover the requirements of these mid-range IoT devices. This new terminal type is called Reduced Capability User Equipment (RedCap UE) or simply New Radio (NR-lite).
[0005] RedCap UEs may be RedCap terminals that support less bandwidth than regular terminals. Summary of the Invention

[0045] Please refer to Figure 1, which shows a schematic diagram of the structure of a wireless communication system provided in an embodiment of this disclosure. As shown in Figure 1, the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system may include: a plurality of UEs 11 and a plurality of access devices 12.
[0046] UE11 can be a device that provides voice and / or data connectivity to a user. UE11 can communicate with one or more core networks via a Radio Access Network (RAN). UE11 can be an IoT UE, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT UE. For example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment (UE). Alternatively, UE11 can be a device in an unmanned aerial vehicle (UAV). Alternatively, UE11 can be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless communication device connected to an external vehicle computer. Alternatively, UE11 can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.
[0047] Access device 12 can be a network-side device in a wireless communication system. This wireless communication system can be a 4G system (also known as Long Term Evolution, LTE); or it can be a 5G system (also known as a New Radio, NR, or 5G NR system). Alternatively, it can be a next-generation system after 5G. In this case, the access network in the 5G system can be called NG-RAN (New Generation-Radio Access Network). Alternatively, it can be an MTC system.
[0048] The access device 12 can be an evolved NB (eNB) used in a 4G system. Alternatively, the access device 12 can also be a gNB (gNB) using a centralized-distributed architecture in a 5G system. When the access device 12 adopts a centralized-distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DUs). The central unit is equipped with a protocol stack of the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the Media Access Control (MAC) layer; the distributed units are equipped with a physical (PHY) layer protocol stack. This disclosure does not limit the specific implementation of the access device 12.
[0049] Access device 12 and UE11 can establish a wireless connection via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth-generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth-generation mobile communication network technology (5G) standard, such as a new air interface; or, the wireless air interface can also be a wireless air interface based on a next-generation mobile communication network technology standard based on 5G.
[0050] In some embodiments, UE11 can also establish E2E (End to End) connections. Examples include V2V (vehicle to vehicle), V2I (vehicle to Infrastructure), and V2P (vehicle to pedestrian) communication scenarios in vehicle-to-everything (V2X) communication.
[0051] In some embodiments, the wireless communication system described above may further include a network management device 13.
[0052] Several access devices 12 are connected to network management device 13. Network management device 13 can be a core network device in a wireless communication system, such as a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, it can be other core network devices, such as a Serving Gateway (SGW), Public Data Network Gateway (PGW), Policy and Charging Rules Function (PCRF), or Home Subscriber Server (HSS). The implementation of network management device 13 is not limited in this embodiment.
[0053] As shown in Figure 2, this embodiment of the present disclosure provides an information processing method, executed by a terminal, the method comprising:
[0054] S210: Determine whether the terminal supports simultaneous downlink reception and uplink transmission;
[0055] S220: Based on the determination result of whether the terminal supports simultaneous downlink reception and uplink transmission, determine the FDD mode in which the terminal operates.
[0056] The terminal can be any terminal, and more specifically, it can be a terminal other than a regular terminal. For example, it can be a RedCap terminal. A RedCap terminal supports less bandwidth than a regular terminal. A regular terminal supports bandwidth equal to the system bandwidth of the communication system. That is, in some embodiments, the bandwidth supported by the terminal can be less than the system bandwidth.
[0057] The maximum bandwidth supported by the ordinary terminal under FR1 is up to 100MHz, and the maximum bandwidth supported under FR2 is up to 400MHz.
[0058] The terminal will automatically determine whether it supports simultaneous downlink reception and uplink transmission based on a predetermined method. If the terminal is determined to be able to simultaneously perform uplink transmission and downlink reception, the FDD mode used by the terminal can be flexibly configured according to this determination result. This determination method can be: pre-negotiated between the terminal and the network device, or based on a protocol agreement.
[0059] For example, S210 may include: determining whether the terminal currently supports simultaneous downlink reception and uplink transmission based on the maximum bandwidth supported by the terminal, the current operating frequency band of the terminal, and one or more of the UL BWP and DL BWP currently monitored by the terminal.
[0060] Simultaneous downlink reception and uplink transmission here means that the terminal can perform downlink reception on one hand and uplink transmission on the other hand at the same time. Moreover, the downlink reception and uplink transmission do not interfere with each other. That is, the simultaneous uplink transmission and downlink reception need to meet various isolation requirements such as communication standards to ensure the communication quality of uplink transmission and downlink reception.
[0061] FDD modes can be divided into at least two types: full-duplex FDD mode and half-duplex FDD mode.
[0062] If the terminal operates in full-duplex FDD mode, it can simultaneously transmit uplink and receive downlink at the same time point. If the terminal operates in half-duplex FDD mode, it can only transmit uplink or receive downlink at any given time.
[0063] That is, S220 may include: determining whether the terminal is operating in full-duplex FDD mode or half-duplex FDD mode based on whether the terminal supports simultaneous uplink transmission and downlink reception.
[0064] As shown in Figure 3, this embodiment of the present disclosure provides an information processing method, executed by a terminal, the method comprising:
[0065] S310: Determine whether the terminal supports simultaneous downlink reception and uplink transmission based on the isolation requirements of the terminal's operating frequency band for uplink transmission and downlink reception.
[0066] S320: Based on the determination result of whether the terminal supports simultaneous downlink reception and uplink transmission, determine the FDD mode in which the terminal operates.
[0067] The terminal can be any terminal, and more specifically, it can be a terminal other than a regular terminal. For example, it can be a RedCap terminal. A RedCap terminal supports less bandwidth than a regular terminal. A regular terminal supports bandwidth equal to the system bandwidth of the communication system. That is, in some embodiments, the bandwidth supported by the terminal can be less than the system bandwidth.
[0068] The terminal operates on multiple frequency bands, and the isolation requirements for uplink transmission and downlink reception are different for different frequency bands.
[0069] Refer to Table 1 for examples illustrating the isolation requirements for uplink transmission and downlink reception corresponding to different operating frequency bands.
[0070] Serial Number | NR Band | Tx-Rx Isolation Requirements | 1N | 1190MHz | 2N | 280MHz | 3N | 395MHz | 4N | 545MHz | 5N | 7120MHz | 6N | 845MHz | 7N | 1230MHz | 8N | 13-31MHz | 9N | 14-30MHz | 10N | 1845MHz | 11N | 20-41MHz | 12N | 24-101.5, -120.5MHz | 13N | 2580MHz | 14N | 2645MHz | 15N | 2855MHz z16N3045MHz17N65190MHz18N66400MHz19N70300MHz20N71-46MHz21N7448MHz22N8530MHz23N91 570-595MHz24N92575-680MHz (u=0) 580-675MHz (u=1) 25N93517MHz-632MHz (u=0) 527MHz-627MHz (u=1) 26N94517MHz-632MHz (u=0) 527MHz-627MHz (u=1) surface
[0071] Table 1
[0072] It is worth noting that one or more elements in Table 1 can be used individually or in combination, and Table 1 shows an example of the terminal's operating frequency band and Tx-Rx isolation requirements. The specific implementation is not limited to the example above.
[0073] Tx-Rx isolation requirements refer to the isolation requirements for uplink transmission and downlink reception.
[0074] In S310, the uplink and downlink BWPs monitored by the terminal meet the isolation requirements of the operating frequency band for uplink transmission and downlink reception. If the isolation requirements are met, the terminal can perform uplink transmission and downlink reception simultaneously, allowing the terminal to operate in full-duplex FDD mode. Otherwise, the terminal can operate in half-duplex FDD mode. The uplink and downlink BWPs include: UL BWP and DL BWP.
[0075] Of course, even if the uplink and downlink BWP monitored by the terminal in the working frequency band meet the isolation requirements, the network equipment on the network side (e.g., base station) can still instruct or suggest that the terminal work in half-duplex FDD mode according to network capacity and service requirements, so as to realize flexible scheduling of the terminal in full-duplex and half-duplex FDD modes according to communication needs, and realize flexible switching of the terminal's working BWP if the terminal's capabilities support it.
[0076] In some embodiments, S310 may specifically include:
[0077] Based on the UL BWP and DL BWP monitored by the terminal in the operating frequency band, and the isolation requirements for uplink transmission and downlink reception, it is determined whether the terminal supports simultaneous downlink reception and uplink transmission.
[0078] A single operating frequency band can be configured with multiple Base Window (BWP) controllers. Different BWPs may be configured with different reference signals or with different information content carried by the same reference signal. The terminal can determine the BWP it is currently monitoring through network configuration. If the terminal can successfully monitor a BWP, that BWP can be used as the terminal's working BWP or active BWP. The terminal can perform uplink transmission and downlink reception on the active BWP. It is understood that in the various embodiments of this disclosure, all UL / DL BWPs monitored by the terminal in the operating frequency band can be active BWPs.
[0079] As shown in Figure 4, this embodiment of the present disclosure provides an information processing method, executed by a terminal, the method comprising:
[0080] S410: Determine whether the frequency difference between the center frequency of the DL BWP and the center frequency of the UL BWP monitored by the terminal in the working frequency band meets the isolation requirements of the uplink transmission and the downlink reception.
[0081] S420: Based on the determination result of whether the terminal supports simultaneous downlink reception and uplink transmission, determine the duplex mode of the terminal's operation.
[0082] The terminal can be any terminal, and more specifically, it can be a terminal other than a regular terminal. For example, it can be a RedCap terminal. A RedCap terminal supports less bandwidth than a regular terminal. A regular terminal supports bandwidth equal to the system bandwidth of the communication system. That is, in some embodiments, the bandwidth supported by the terminal can be less than the system bandwidth.
[0083] Referring to Figure 5, if the terminal detects that the UL BWP of its operating frequency band is UL BWP2, and simultaneously detects that the DL BWP of its operating frequency band is DL BWP2, in this embodiment of the disclosure, it will determine whether the frequency difference between the center frequency of UL BWP2 and the center frequency of DLBWP2 meets the isolation requirements for uplink transmission and downlink reception.
[0084] In Figure 5, the horizontal axis represents frequency (F), and the arrows on the horizontal axis point in the direction of frequency increase. Figure 5 shows the UL bandwidth and DL bandwidth of the system bandwidth. The UL system bandwidth is used for uplink transmission of the terminal, and the DL system bandwidth is used for downlink reception of the terminal.
[0085] One or more DL BWPs are configured on the DL system bandwidth; one or more UL BWPs are configured on the UL system bandwidth. Multiple BWPs on the DL system bandwidth can be sequentially numbered and ordered, and multiple BWPs on the UL system bandwidth can be sequentially numbered and ordered.
[0086] For example, assuming the terminal's current operating frequency band is N3, and the terminal detects both UL BWP1 and DLBWP1, the terminal will calculate the difference between the center frequencies of UL BWP1 and DLBWP1. If the difference is less than 95MHz, it means that the terminal does not currently support simultaneous downlink reception and uplink transmission. If the difference is greater than or equal to 95MHz, it means that the terminal currently supports simultaneous downlink reception and uplink transmission.
[0087] For example, assuming the terminal's current operating frequency band is N7, and the terminal simultaneously detects UL BWP2 and DL BWP1, and the difference between the center frequency of UL BWP2 and the center frequency of DL BWP1 is less than 120MHz, it can be considered that if the terminal performs uplink transmission on UL BWP2 and downlink reception on DL BWP1, it will cause mutual interference between uplink transmission and downlink reception, that is, the isolation requirements for uplink transmission and downlink reception are not met. Therefore, it can be considered that the terminal currently does not support simultaneous uplink transmission and downlink reception.
[0088] As shown in Figure 6, this embodiment of the present disclosure provides an information processing method, executed by a terminal, the method comprising:
[0089] S610: Determine whether the frequency difference between the lowest frequency point of the DL BWP and the highest frequency point of the UL BWP monitored by the terminal in the working frequency band meets the isolation requirements of the uplink transmission and the downlink reception.
[0090] S620: Based on the determination result of whether the terminal supports simultaneous downlink reception and uplink transmission, determine the FDD mode in which the terminal operates.
[0091] The terminal can be any terminal, and more specifically, it can be a terminal other than a regular terminal. For example, it can be a RedCap terminal. A RedCap terminal supports less bandwidth than a regular terminal. A regular terminal supports bandwidth equal to the system bandwidth of the communication system. That is, in some embodiments, the bandwidth supported by the terminal can be less than the system bandwidth.
[0092] The terminal can be configured with a channel bandwidth (BW), which is generally greater than the bandwidth of a single BWP. The upper boundary value of this channel bandwidth may coincide exactly with a boundary of a detected BWP, or it may not overlap with the boundary value of any detected BWP; and / or, similarly, the lower boundary value of this channel bandwidth may coincide exactly with a boundary of a detected BWP, or it may not overlap with the boundary value of any detected BWP.
[0093] Referring to Figure 7, the terminal simultaneously monitors both the UL system bandwidth (UL BWP2) and the DL system bandwidth (DL BWP2) of its operating frequency band. It then determines the lowest frequency point of DL BWP2 and the highest frequency point of UL BWP2. The difference between the lowest frequency point of DL BWP2 and the highest frequency point of UL BWP2 is then calculated to obtain the frequency difference mentioned in this embodiment. Based on this frequency difference, it is determined whether the isolation requirements for uplink transmission and downlink reception are met.
[0094] For example, determining whether the frequency difference between the lowest frequency point of the DL BWP and the highest frequency point of the UL BWP monitored by the terminal in the operating frequency band meets the isolation requirements of the uplink transmission and the downlink reception includes:
[0095] Determine whether the frequency difference between the lowest frequency point of the DL BWP and the highest frequency point of the UL BWP detected by the terminal meets the isolation requirements of the first threshold.
[0096] For example, when the uplink channel bandwidth of the terminal is equal to the downlink channel bandwidth, the first threshold can be equal to: Fs-BW; where Fs can be the isolation bandwidth value between uplink transmission and downlink reception in the operating frequency band of the terminal, and BW can be the uplink channel bandwidth or downlink channel bandwidth supported by the terminal.
[0097] For example, in the case where the uplink channel bandwidth of the terminal is not equal to the downlink channel bandwidth, the first threshold can be equal to: Fs - 0.5 * uplink channel bandwidth - 0.5 * downlink channel bandwidth.
[0098] This is merely an example of the first threshold; the actual implementation is not limited to this example.
[0099] Here, determining whether the frequency difference between the lowest frequency point of the DL BWP and the highest frequency point of the UL BWP detected by the terminal meets the isolation requirement of the first threshold may include at least:
[0100] The frequency difference between the lowest frequency point of the DL BWP and the highest frequency point of the UL BWP detected by the terminal is greater than a first threshold.
[0101] In this embodiment of the disclosure, if the frequency difference between the lowest frequency point of the DL BWP and the highest frequency point of the UL BWP detected by the terminal is greater than a first threshold, it can be considered that the terminal currently supports simultaneous uplink transmission and downlink reception; otherwise, it can be considered that the terminal currently does not support simultaneous uplink transmission and downlink reception.
[0102] As shown in Figure 8, this embodiment of the present disclosure provides an information processing method, executed by a terminal, the method comprising:
[0103] S810: Determine whether the frequency difference between the lowest frequency point of the UL BWP and the highest frequency point of the DL BWP monitored by the terminal in the working frequency band meets the isolation requirements of the uplink transmission and the downlink reception.
[0104] S820: Based on the determination result of whether the terminal supports simultaneous downlink reception and uplink transmission, determine the FDD mode in which the terminal operates.
[0105] The terminal can be any terminal, and more specifically, it can be a terminal other than a regular terminal. For example, it can be a RedCap terminal. A RedCap terminal supports less bandwidth than a regular terminal. A regular terminal supports bandwidth equal to the system bandwidth of the communication system. That is, in some embodiments, the bandwidth supported by the terminal can be less than the system bandwidth.
[0106] As shown in Figure 9, assuming that the terminal detects that the UL BWP of the system bandwidth in its operating frequency band is UL BWP2, and at the same time detects that the DL BWP of the system bandwidth is UL BWP2, the terminal will determine the lowest frequency point of UL BWP2 and the highest frequency point of DL BWP2, and calculate the frequency difference between the determined lowest frequency point of UL BWP2 and the highest frequency point of DL BWP2 to see if the isolation requirements for uplink transmission and downlink reception in the current operating frequency band of the terminal are met.
[0107] For example, S810 may include: determining whether the frequency difference between the lowest frequency point of the UL BWP and the highest frequency point of the DL BWP monitored by the terminal meets the isolation requirements of the second threshold.
[0108] When the uplink channel bandwidth supported by the terminal is equal to the downlink channel bandwidth, the second threshold can be equal to Fs + BW; where Fs can be the isolation bandwidth value between uplink transmission and downlink reception in the terminal's operating frequency band, and BW can be the uplink channel bandwidth or downlink channel bandwidth supported by the terminal.
[0109] When the uplink channel bandwidth supported by the terminal is not equal to the downlink channel bandwidth, the second threshold can be equal to Fs + 0.5 * uplink channel bandwidth + 0.5 * downlink channel bandwidth.
[0110] Of course, the above is just an example of the second threshold, and the actual implementation is not limited to the above example.
[0111] Determining whether the frequency difference between the lowest frequency point of the UL BWP and the highest frequency point of the DL BWP monitored by the terminal meets the isolation requirement of the second threshold may include at least the following:
[0112] Determine whether the frequency difference between the lowest frequency point of the UL BWP and the highest frequency point of the DL BWP monitored by the terminal is less than a second threshold.
[0113] In this embodiment of the disclosure, if the frequency difference between the highest frequency point of the DL BWP and the lowest frequency point of the UL BWP detected by the terminal is less than the second threshold, it can be considered that the terminal currently supports simultaneous uplink transmission and downlink reception; otherwise, it can be considered that the terminal currently does not support simultaneous uplink transmission and downlink reception.
[0114] In some embodiments, determining whether a terminal supports simultaneous uplink transmission and downlink reception may include:
[0115] The system determines whether the frequency difference between the lowest frequency of the DL BWP and the highest frequency of the UL BWP monitored by the terminal in the operating frequency band meets the isolation requirements for uplink transmission and downlink reception, and also determines whether the frequency difference between the lowest frequency of the UL BWP and the highest frequency of the DL BWP monitored by the terminal in the operating frequency band meets the isolation requirements for uplink transmission and downlink reception. For example, if the frequency difference between the center frequency of the DL BWP and the center frequency of the UL BWP monitored by the terminal in the operating frequency band meets a first threshold isolation requirement, and if the frequency difference between the lowest frequency of the UL BWP and the highest frequency of the DL BWP monitored by the terminal meets a second threshold isolation requirement, it can be determined that the terminal supports simultaneous uplink transmission and downlink reception; otherwise, it can be considered that the terminal does not support simultaneous uplink transmission and downlink reception.
[0116] In some embodiments, determining the frequency division duplex (FDD) mode in which the terminal operates based on the determination result of whether the terminal supports simultaneous downlink reception and uplink transmission includes:
[0117] When the terminal supports simultaneous downlink reception and uplink transmission, it is determined that the terminal is operating in full-duplex FDD mode;
[0118] When the terminal does not support simultaneous downlink reception and uplink transmission, it is determined that the terminal is operating in half-duplex FDD mode.
[0119] Terminals operating in full-duplex FDD mode will simultaneously open the radio frequency paths corresponding to the UL BWP and the DL BWP, thereby enabling uplink transmission and downlink reception at the same time domain location.
[0120] A terminal operating in half-duplex FDD mode can only operate in either UL BWP or DL BWP at a time. Therefore, when the terminal is operating in DL BWP, if it needs to perform uplink transmission, it must switch to UL BWP via uplink / downlink handover before transmitting. Similarly, when the terminal is operating in UL BWP, if it needs to perform downlink reception, it must switch to DL BWP via uplink / downlink handover before receiving.
[0121] Of course, in some embodiments, even if the terminal supports simultaneous downlink reception and uplink transmission, considering the terminal's power consumption and service characteristics—for example, some terminals actually have a much greater need for uplink transmission than downlink reception, or vice versa—the terminal can still choose to operate in half-duplex FDD mode based on its own service requirements. Furthermore, if the terminal operates in half-duplex FDD mode, it will further optimize its operation based on the terminal's service characteristics or needs, preferably on the UL BWP or DL BWP with high service demand, to reduce the number of uplink / downlink handovers in half-duplex FDD mode.
[0122] As shown in Figure 10, this embodiment of the present disclosure provides an information processing method, executed by a terminal, the method comprising:
[0123] S1010: When the terminal is working in half-duplex FDD mode, it performs downlink reception or uplink transmission according to the preset priority.
[0124] The information processing method provided in this embodiment can be executed alone, or in combination with the information processing method executed by any of the aforementioned terminals.
[0125] For example, the determination of whether the terminal is operating in the half-duplex FDD mode can be made using the information processing method provided in the foregoing embodiments, or it can be made using other methods. For instance, the terminal can determine whether it is operating in the half-duplex FDD mode based on the user configuration or default configuration of the terminal.
[0126] The terminal can be a regular terminal and / or the aforementioned RedCap terminal.
[0127] When a terminal operates in half-duplex FDD mode, it is inevitable that downlink reception and uplink transmission may conflict at some point in time. To resolve this conflict, pre-priority is introduced.
[0128] For example, base stations or protocols can pre-configure priorities for various uplink transmissions and downlink receptions. When a terminal detects a conflict, it will automatically prioritize transmissions with higher preset priorities and abandon transmissions with lower priorities. This reduces the phenomenon where the terminal cannot properly coordinate transmissions when operating in half-duplex FDD mode and there are both UL and DL transmissions at the same time domain location, thus ensuring the communication quality of the terminal.
[0129] In some embodiments, when the terminal is operating in the half-duplex FDD mode, performing downlink reception or uplink transmission according to a preset priority includes at least one of the following:
[0130] When the uplink transmission of the terminal conflicts with the downlink reception of the synchronization signal block (SSB), the reception of the SSB is performed according to the preset priority.
[0131] When the uplink transmission of the terminal's dynamic scheduling conflicts with the downlink reception of the semi-static configuration, the uplink transmission of the dynamic scheduling is executed according to the preset priority;
[0132] When the downlink reception of the terminal's dynamic scheduling conflicts with the uplink transmission of the semi-static configuration, the downlink reception of the dynamic scheduling is executed according to the preset priority.
[0133] For example, the terminal prioritizes the reception of SSBs, which can enable the measurement of the local cell and / or neighboring cells. This allows the terminal to switch or reselect to a more suitable cell in a timely manner when there are fluctuations in cell communication quality before or after movement, thus ensuring the communication quality of the UE. The uplink transmission of the UE can be performed after the downlink reception of the SSB is completed.
[0134] For example, network devices can perform semi-static configuration using semi-static instructions. These semi-static instructions include, but are not limited to, RRC instructions. A semi-static instruction configures multiple transmissions according to a semi-static cycle within a semi-static configuration timeframe. The terminal will execute the corresponding transmission when the corresponding semi-static cycle is reached, based on the semi-static configuration.
[0135] For example, when the other device makes a call or sends a message, the network device may dynamically schedule the terminal's transmission. For instance, DCI may be used to dynamically schedule the terminal's uplink transmission and / or downlink reception. In this case, dynamically scheduled uplink transmission may conflict with semi-static downlink reception. In view of this, considering that dynamic scheduling may be emergency scheduling, while semi-static configuration can transmit in the next semi-static cycle, the dynamically scheduled uplink transmission will be given priority according to the preset priority.
[0136] Of course, if there is a conflict between the uplink transmission configured in semi-static configuration and the downlink reception configured in dynamic scheduling, the downlink reception configured in semi-static configuration can be prioritized and the transmission of the uplink transmission configured in semi-static configuration can be postponed, taking into account that dynamic scheduling is usually for urgent services.
[0137] The uplink transmission and / or downlink reception of the currently suspended semi-static configuration can be completed in one or more subsequent semi-static cycles.
[0138] As shown in Figure 11, this embodiment of the present disclosure provides an information processing method, executed by a terminal, the method comprising:
[0139] S1110: If the terminal is operating in half-duplex FDD mode and the uplink transmission and downlink reception of the semi-static configuration are determined to conflict in the time domain according to the semi-static configuration, the terminal may consider this semi-static configuration to be an invalid configuration or an incorrect configuration.
[0140] If the terminal detects a wireless configuration error, it can ignore the corresponding semi-static configuration; or, it can report an invalid or incorrect configuration to the network device (e.g., a base station).
[0141] The information processing method provided in this embodiment can be executed alone, or in combination with the information processing method executed by any of the aforementioned terminals.
[0142] For example, the determination of whether the terminal is operating in the half-duplex FDD mode can be made using the information processing method provided in the foregoing embodiments, or it can be made using other methods. For instance, the terminal can determine whether it is operating in the half-duplex FDD mode based on the user configuration or default configuration of the terminal.
[0143] As another example, this information processing method can also be used to resolve two or more transmissions with the same time-domain location using a predetermined priority, as shown in Figure 10.
[0144] The terminal can be a regular terminal and / or the aforementioned RedCap terminal.
[0145] As shown in Figure 12, this embodiment of the present disclosure provides an information processing method, wherein the method is executed by a network device, and the method includes:
[0146] S1210: The network device determines whether the terminal supports simultaneous downlink reception and uplink transmission;
[0147] S1220: Based on the determination result of whether the terminal supports simultaneous downlink reception and uplink transmission, determine the FDD mode in which the terminal operates.
[0148] The network device can be any access network device; for example, the access network device can be a base station. The base station can be a gNB or an eNB.
[0149] The network device will determine, based on a predetermined method, whether the terminal supports simultaneous downlink reception and uplink transmission. If the terminal is confirmed to be capable of simultaneous uplink transmission and downlink reception, the FDD mode used by the terminal can be flexibly configured accordingly. This determination method can be pre-negotiated between the terminal and the network device, or based on a protocol agreement.
[0150] Ultimately, the network device will determine the FDD mode of the terminal's operation based on whether the terminal supports both downlink reception and uplink transmission simultaneously.
[0151] Furthermore, after determining the FDD mode in which the terminal is operating, the network device will perform resource scheduling and / or transmission scheduling for the terminal based on the FDD mode, so as to achieve orderly uplink and downlink scheduling and transmission while taking into account the bandwidth supported by the terminal.
[0152] In some embodiments, S1210 may include: determining whether the terminal supports simultaneous downlink reception and uplink transmission based on the isolation requirements of uplink transmission and downlink reception in the terminal's operating frequency band.
[0153] Wireless communication can be configured with multiple frequency bands, and different frequency bands may have different isolation requirements for uplink transmission and downlink reception. For example, the isolation requirements for different operating frequency bands are shown in Table 1, but the actual implementation is not limited to Table 1.
[0154] Thus, based on the isolation requirements of the terminal's operating frequency, it can be determined whether the terminal supports simultaneous downlink reception and uplink transmission on the current operating frequency band.
[0155] In some embodiments, determining whether the terminal supports simultaneous downlink reception and uplink transmission based on the isolation requirements of the terminal's uplink transmission and downlink reception includes:
[0156] Based on the UL BWP and DL BWP monitored by the terminal in the operating frequency band, and the isolation requirements for uplink transmission and downlink reception, it is determined whether the terminal supports simultaneous downlink reception and uplink transmission.
[0157] A frequency band may be configured with one or more BWPs. The terminal may only be able to detect some of the BWPs at present. To determine whether the terminal can support simultaneous uplink transmission and downlink reception, if the terminal detects UL BWP and DL BWP, it means that the terminal's current bandwidth can cover the upper and lower BWPs. At this time, based on the isolation requirements of uplink transmission and downlink reception corresponding to the terminal's operating frequency point, it can be determined whether the terminal can simultaneously perform downlink reception and uplink transmission on the currently monitored BWP.
[0158] The terminal can determine the BWP it is currently monitoring by listening to reference signals. If the terminal successfully monitors a BWP, that BWP can be used as the terminal's working BWP, or active BWP. The terminal can perform uplink transmission and downlink reception on the active BWP.
[0159] After the terminal detects the corresponding BWP, it can notify the network device. In this way, the network device will know which BWP the terminal has detected. On the one hand, after receiving this notification, the network device can schedule the BWPs that the terminal is working on. On the other hand, after receiving this notification, the network device can also determine whether the current terminal supports uplink transmission and downlink reception simultaneously based on the BWPs detected by the terminal and the isolation requirements for uplink transmission and downlink reception, and further determine the FDD mode that the terminal is working on.
[0160] For example, the terminal may carry a flag bit and a BWP number within the notification. The flag bit may include one or more bits indicating whether the monitored BWP is a UL BWP or a DL BWP. Further, the BWP number may indicate the number of the monitored ULBWP and / or the number of the DL BWP.
[0161] In some embodiments, determining whether the terminal supports simultaneous downlink reception and uplink transmission based on the UL BWP and DL BWP monitored by the terminal in the operating frequency band, and the isolation requirements of uplink transmission and downlink reception, includes at least one of the following:
[0162] Determine whether the frequency difference between the center frequency of the DL BWP and the center frequency of the UL BWP monitored by the terminal in the working frequency band meets the isolation requirements of the uplink transmission and the downlink reception.
[0163] Determine whether the frequency difference between the lowest frequency point of the DL BWP and the highest frequency point of the UL BWP monitored by the terminal in the working frequency band meets the isolation requirements of the uplink transmission and the downlink reception.
[0164] Determine whether the frequency difference between the lowest frequency point of the UL BWP and the highest frequency point of the DL BWP monitored by the terminal in the operating frequency band meets the isolation requirements of the uplink transmission and the downlink reception.
[0165] The terminal detects the center frequency, lowest frequency, and highest frequency of the DL BWP and UL BWP in the operating frequency band, as shown in Figures 5, 7, and 9, which will not be repeated here.
[0166] In some embodiments, determining whether the frequency difference between the lowest frequency point of the DL BWP and the highest frequency point of the ULBWP monitored by the terminal in the operating frequency band meets the isolation requirements for uplink transmission and downlink reception includes:
[0167] Determine whether the frequency difference between the lowest frequency point of the DL BWP and the highest frequency point of the UL BWP detected by the terminal meets the isolation requirements of the first threshold.
[0168] For example, when the uplink channel bandwidth of the terminal is equal to the downlink channel bandwidth, the first threshold can be equal to: Fs-BW; where Fs can be the isolation bandwidth value between uplink transmission and downlink reception in the operating frequency band of the terminal, and BW can be the uplink channel bandwidth or downlink channel bandwidth supported by the terminal.
[0169] For example, in the case where the uplink channel bandwidth of the terminal is not equal to the downlink channel bandwidth, the first threshold can be equal to: Fs - 0.5 * uplink channel bandwidth - 0.5 * downlink channel bandwidth.
[0170] This is merely an example of the first threshold; the actual implementation is not limited to this example.
[0171] In some embodiments, determining whether the frequency difference between the lowest frequency point of the UL BWP and the highest frequency point of the DL BWP monitored by the terminal in the operating frequency band meets the isolation requirements for uplink transmission and downlink reception includes:
[0172] Determine whether the frequency difference between the lowest frequency point of the UL BWP and the highest frequency point of the DL BWP monitored by the terminal meets the isolation requirements of the second threshold.
[0173] When the uplink channel bandwidth supported by the terminal is equal to the downlink channel bandwidth, the second threshold can be equal to Fs + BW; where Fs can be the isolation bandwidth value between uplink transmission and downlink reception in the terminal's operating frequency band, and BW can be the uplink channel bandwidth or downlink channel bandwidth supported by the terminal.
[0174] When the uplink channel bandwidth supported by the terminal is not equal to the downlink channel bandwidth, the second threshold can be equal to Fs + 0.5 * uplink channel bandwidth + 0.5 * downlink channel bandwidth.
[0175] Of course, the above is just an example of the second threshold, and the actual implementation is not limited to the above example.
[0176] In this embodiment of the disclosure, if the frequency difference between the highest frequency point of the DL BWP and the lowest frequency point of the UL BWP detected by the terminal is less than the second threshold, it can be considered that the terminal currently supports simultaneous uplink transmission and downlink reception; otherwise, it can be considered that the terminal currently does not support simultaneous uplink transmission and downlink reception.
[0177] In some embodiments, S1220 may include:
[0178] When the terminal supports simultaneous downlink reception and uplink transmission, it is determined that the terminal is operating in full-duplex FDD mode;
[0179] When the terminal does not support simultaneous downlink reception and uplink transmission, it is determined that the terminal is operating in half-duplex FDD mode.
[0180] Of course, in the actual implementation process, even if the terminal currently supports simultaneous uplink transmission and downlink reception, it can be configured to work in half-duplex FDD mode. For example, the terminal can be configured to work in half-duplex FDD mode based on factors such as the terminal's service requirements and / or network load rate.
[0181] As shown in Figure 13, this embodiment of the present disclosure provides an information processing method, which is executed by a network device. The method includes: S1310: When the terminal is working in half-duplex FDD mode, the uplink transmission and downlink reception configurations of the terminal are configured in a semi-static manner at different time domain positions.
[0182] S1320: When the terminal does not expect the semi-static configuration of uplink transmission and downlink reception to be located in the same time domain, the semi-static configuration of uplink transmission and downlink reception of the terminal is configured in different time domain locations.
[0183] This embodiment can be implemented alone or in combination with any of the aforementioned embodiments of information processing methods executed by a network device. For example, it can be implemented in combination with the information processing method shown in FIG12.
[0184] For example, when a terminal operates in half-duplex FDD mode, or when the base station determines that the terminal does not expect the uplink transmission and downlink reception to be in the same time domain in a semi-static configuration, or when the terminal informs the base station that the uplink transmission and downlink reception in a semi-static configuration are in the same time domain, the uplink transmission and downlink reception will be configured in different time domain locations when performing semi-static configuration for such a terminal.
[0185] The terminal does not expect the semi-static configuration of uplink transmission and downlink reception to be located at the same time domain position. There are several situations, and two specific examples are provided below:
[0186] If the terminal determines that it is operating in half-duplex FDD mode, then the terminal does not expect the uplink transmission and downlink reception in the semi-static configuration to be located in the same time domain.
[0187] If the terminal supports simultaneous uplink transmission and downlink reception, but the terminal determines, based on its own service characteristics, that it does not expect the semi-static configuration of uplink transmission and downlink reception to be located in the same time domain.
[0188] As shown in Figure 14, this embodiment of the present disclosure provides an information processing method, which is executed by a network device, and the method includes:
[0189] S1410: When the terminal is working in the half-duplex FDD mode, the terminal is determined to perform downlink reception or uplink transmission according to the preset priority.
[0190] This embodiment can be implemented alone or in combination with any of the aforementioned embodiments of information processing methods performed by a network device. For example, it can be implemented in combination with the information processing methods shown in FIG12 and / or FIG13.
[0191] For example, determining whether the terminal performs downlink reception or uplink transmission according to a preset priority includes at least one of the following:
[0192] When the uplink transmission of the terminal conflicts with the downlink reception of the synchronization signal block (SSB), it is determined that the terminal will perform the reception of the SSB.
[0193] When the uplink transmission of the terminal in dynamic scheduling conflicts with the downlink reception in semi-static configuration, it is determined that the terminal will perform the uplink transmission in dynamic scheduling.
[0194] When the downlink reception of the terminal's dynamic scheduling conflicts with the uplink transmission of the semi-static configuration, it is determined that the terminal will perform the downlink reception of dynamic scheduling.
[0195] In some embodiments, if it is determined that the terminal is performing dynamically scheduled uplink transmission, the base station needs to receive the uplink transmission at the corresponding time-frequency resource location according to the dynamic scheduling instruction.
[0196] In other embodiments, if it is determined that the terminal is performing dynamically scheduled downlink reception, the base station performs downlink transmission at the corresponding time-frequency resource location according to the semi-static configuration.
[0197] For ordinary terminals, since the channel bandwidth (BW) on the terminal side can be as large as the system bandwidth, in an FDD system, the DL BWP and UL BWP can be switched independently, and the isolation requirements of uplink transmission and downlink reception (Tx-Rx separation) can still be guaranteed.
[0198] However, for RedCap terminals, the reduction in terminal bandwidth and the switching of BWP bandwidth will lead to the switching of the transceiver center frequency. In some cases, the interval between the transceiver frequency points can no longer meet the isolation requirements of the uplink transmission and downlink reception mentioned above.
[0199] When the interval between the transmit and receive frequencies cannot meet the isolation requirements for uplink transmission and downlink reception, the terminal will be unable to transmit and receive simultaneously.
[0200] To ensure the flexibility of BWP handover in the FDD system, and also to guarantee the operational order of the terminal under relaxed Tx-Rx isolation requirements, the embodiments of this disclosure provide the following solution:
[0201] The terminal and / or network device determine whether the terminal supports simultaneous downlink reception and uplink transmission based on preset conditions.
[0202] In response to the terminal's inability to simultaneously receive downlink data and transmit uplink data (referred to as "transmit and receive"), the terminal operates in HD-FDD mode.
[0203] In response to the terminal's ability to simultaneously receive downlink data and transmit uplink data, the terminal operates in FD-FDD mode.
[0204] The preset conditions are determined based on preset Tx-Rx separation requirements. For example, different operating frequency bands have different frequency band requirements for uplink transmission and downlink reception.
[0205] The preset condition is that the center frequency of the target DL BWP and the center frequency of the target UL BWP of the terminal meet the preset Tx-Rx separation requirements.
[0206] For example, if a terminal operates in a certain frequency band and the preset Tx-Rx separation requirement is FsMHz, then the preset condition is to determine that the center frequency interval between the active DL BWP and the active UL BWP of the terminal is Fs MHz.
[0207] The difference between the lowest frequency point of the terminal's DL BWP and the highest frequency point of the UL BWP is greater than a certain threshold.
[0208] And / or,
[0209] The difference between the lowest frequency point of the UL BWP and the highest frequency point of the DL BWP of the terminal is less than a certain threshold.
[0210] For example, if the preset Tx-Rx separation requirement for a certain band is Fs MHz, the terminal's channel bandwidth is determined by: the lowest frequency of the terminal's active DL BWP and the highest frequency of the active UL BWP are greater than Fs-BW.
[0211] The highest frequency of the active DL BWP and the lowest frequency of the active UL BWP are less than Fs+BW.
[0212] The terminal is determined to be operating in HD-FDD mode based on preset conditions.
[0213] Network devices and / or terminals perform uplink transmission or downlink reception according to the HD-FDD transmit and receive priorities, and the handling rules for resolving transmit and receive conflicts according to priorities are as follows:
[0214] When the uplink transmission of the terminal conflicts with the downlink reception of the SSB, the terminal abandons the uplink transmission and prioritizes the downlink reception of the SSB.
[0215] When there is a conflict between dynamically scheduled uplink / downlink transmissions and semi-statically configured downlink / uplink transmissions, dynamically scheduled uplink / downlink transmissions take precedence over semi-statically configured downlink / uplink transmissions.
[0216] Terminals do not expect uplink and downlink in semi-static configurations to occur at the same time domain location, so this can be determined by the scheduling configuration of the base station for the terminal.
[0217] The terminal determines whether the configuration of the BWP pair meets the conditions for Tx-Rx separation, and determines the duplex mode of the terminal based on the judgment result.
[0218] As shown in Figure 15, this embodiment of the present disclosure provides an information processing apparatus, wherein the apparatus includes:
