Cellular phones and smart home devices can communicate without relaying communication signals through a base station.

[0033] The network device in this application embodiment can be a device for communicating with a terminal device. This network device can also be called an access network device or a wireless access network device, such as a base station.

[0037] It should be understood that all or part of the functions of the communication device in this application can also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (e.g., a cloud platform).

[0038] Carrier aggregation (CA)

[0039] Capable Aspect (CA) is a bandwidth extension technology supported in the LTE-Advanced (LTE-A) standard and its subsequent standards. CA aims to extend bandwidth by aggregating multiple component carriers (CCs) together, allowing a single UE to simultaneously receive or transmit data. Depending on the range of the aggregated carriers, CA can be divided into intra-band CA and inter-band CA. Intra-band CA is particularly suitable for scenarios where the cell carrier bandwidth exceeds the UE's single-carrier bandwidth capability. In this case, the UE can use CA to operate on a "wide carrier."

[0040] For example, a network device (such as a base station (eNB)) supports a 300MHz carrier, while the UE only supports a maximum of 100MHz carriers. In this case, the UE can use CA (Carrier Aggregation) to achieve broadband operation greater than 100MHz. The carriers aggregated by CA can be adjacent or non-adjacent carriers. In CA, the network device can directly activate / deactivate carriers. As shown in Figure 2, among the three carriers (CCs), carrier 1 (CC1) and carrier 2 (CC2) are activated, while carrier 3 (CC3) is not activated. In this case, the UE is performing carrier aggregation of two CCs (200MHz).

[0041] NR, as the next-generation standard of LTE-A, introduces a Bandwidth Part (BWP). The BWP is embedded within the carrier, meaning that under the NR standard, the carrier is no longer a fixed, all-time resource block, but can be further subdivided into multiple smaller, independently configurable and activating / deactivating BWPs. Each BWP can have different configurations, such as different subcarrier spacing and cyclic prefix lengths, and can be dynamically allocated to the UE as needed. The configuration parameters of the carrier and BWP are somewhat similar, both including bandwidth and frequency location. However, the configuration and definition of BWPs are more flexible; the UE does not need to know the bandwidth of the carrier it is activating, but only needs to flexibly configure and activate the BWP.

[0042] The design of NR carriers is similar to that of LTE carriers. For example, NR carrier activation still uses MAC CE activation instead of DCI-based carrier activation.

[0043] NR employs a two-layer configuration and activation approach using carriers and BWPs to support CA. Here, a BWP is a concept within a single carrier, and the configuration and activation / deactivation of the carrier and BWPs are designed separately. Carrier activation still uses the traditional method: one BWP can be activated within each active carrier; that is, the carrier must be activated first before the BWPs within that carrier can be activated. If a carrier is deactivated, the active BWPs within that carrier are also deactivated simultaneously. As an example, in Figure 3, among the three carriers (CCs), carrier 1 (CC1) and carrier 2 (CC2) are activated, meaning the UE performs carrier aggregation on two carriers (200MHz). Carrier 1 (CC1) also has a 100MHz BWP activated, and carrier 2 (CC2) has a 50MHz BWP activated. Carrier 3 (CC3) is not activated, therefore no BWPs can be activated within carrier 3. Thus, when a carrier (CC) is deactivated, naturally, all BWPs within that carrier (CC) are simultaneously deactivated. In summary, in the R15 NR system, only one BWP can be activated within each CC, but when performing carrier aggregation of N CCs, N BWPs can be activated simultaneously.

[0044] Under the NR R15 / R16 standard, UE design needs to support extremely high peak rates. To achieve such high rates, the UE needs to possess high performance and capabilities. For example, the LTE standard defines a maximum single-carrier bandwidth of 20MHz, with larger bandwidths achieved through multi-carrier aggregation. The 5G NR standard, however, defines a maximum carrier bandwidth of 100MHz for frequencies below 6GHz (five times the single-carrier bandwidth of LTE), and a maximum carrier bandwidth of 400MHz for millimeter-wave frequencies. Furthermore, the LTE standard's UE antenna reference configuration is one transmit and two receive, while the NR R15 standard requires dual transmit and four receive antennas for frequencies above 2500MHz. This demonstrates that the MIMO antenna scale required by the NR standard is further increased. Additionally, the NR R15 / R16 standard does not support half-duplex, but requires data processing for all uplink and downlink time slots.

[0045] In summary, existing carrier aggregation and BWP mechanisms allocate complete frequency domain resources for each carrier or BWP, which requires the UE to maintain access with high processing power and power consumption. This approach is suitable for high-speed scenarios, and such carrier resource configuration is appropriate in high-speed scenarios.

[0046] However, in some NR application scenarios (including but not limited to IoT, industrial automation, and wearable device applications), it is not always necessary to maintain such high load and power consumption resources. Therefore, UEs in these application scenarios do not require the high processing capabilities (e.g., processing capacity and speed) of NR R15 / R16. Furthermore, these scenarios typically require UE communication hardware with low size and power consumption. Lightweight capability is a characteristic of UEs in these scenarios. Based on this, the configuration of LTE and NR R15 / R16 carrier resources is somewhat unsuitable in these application scenarios.

[0047] Based on these considerations, NR R17 introduced a compact terminal standard with reduced capabilities. The compact terminal standard reduces some mandatory capabilities of NR 15 / 16. Corresponding terminal function groups are defined for these capabilities. The compact terminal standard also further optimizes terminal device identification, access procedures, and power consumption in measurements to adapt to relevant application scenarios. The compact terminal design of NR R17 can significantly reduce the hardware complexity of the UE, while also correspondingly reducing UE power consumption, thus achieving energy saving. In view of this, in future communications, the framework of carrier aggregation and BWP needs to consider supporting low-load UE camping in some carriers or resource groups. Therefore, how to effectively utilize carrier resources in future communications has become an urgent problem to be solved.

[0048] To address the aforementioned issues, this application provides a communication method in which a terminal device can receive configuration information from a network device. This configuration information is used to configure a first type of frequency unit and / or one or more second type frequency units. By introducing configuration information for configuring the two types of frequency units, this method enables flexible use of carrier resources, helps optimize the power consumption and complexity of the terminal device, and improves the design flexibility of the terminal device, providing a more optimized solution for the application of future communication technologies in diverse scenarios.

[0049] The communication method provided in this application embodiment will be described in detail below with reference to Figure 4. As shown in Figure 4, the communication method 400 provided in this application embodiment includes step S410. It should be noted that the method in Figure 4 is described from the perspective of the interaction between the terminal device and the network device described above.

[0050] In step S410, the terminal device receives configuration information sent by the network device.

[0051] The configuration information is used to configure the first type of frequency unit and / or one or more second type of frequency units.

[0052] In some embodiments, the configuration information is used to configure a first type of frequency unit. Therefore, the configuration information includes configuration information corresponding to the first type of frequency unit.

[0053] In other embodiments, the configuration information is used to configure a first type of frequency unit and a second type of frequency unit. Therefore, the configuration information includes configuration information corresponding to the first type of frequency unit and configuration information corresponding to the second type of frequency unit.

[0054] In other embodiments, the configuration information is used to configure a first type of frequency unit and a plurality of second type frequency units. Therefore, the configuration information includes configuration information corresponding to the first type of frequency unit and configuration information corresponding to each of the plurality of second type frequency units.

[0055] The first type of frequency unit can also be called a base frequency unit or base carrier. The first type of frequency unit is used by terminal devices to perform basic communication functions. These basic communication functions can be, for example, the communication functions possessed by terminal devices in applications such as the Internet of Things (IoT), industrial automation, and wearable devices. As an example, the basic communication function is the communication function possessed by a zero-power terminal device. As another example, the basic communication function is the communication function possessed by a wearable device.

[0056] The first type of frequency unit is used to configure (or, can be understood as the configuration information corresponding to the first type of frequency unit being used to configure) one or more of the following: resources corresponding to the first type of frequency unit; initial access channel; periodic measurement channel; first control / data channel.

[0057] In some embodiments, the first type of frequency unit is also used to configure corresponding low-rate transmission resources.

[0058] The resources corresponding to the first frequency unit may include, but are not limited to, one or more of the following: time-domain resources, frequency-domain resources, and spatial resources corresponding to the first frequency unit.

[0059] The initial access channel is used for the terminal device to connect to the network for the first time.

[0060] Periodic measurement channels are used to periodically evaluate network performance. Periodic channels can be fixed or non-fixed. In some embodiments, a periodic measurement channel includes both a periodic measurement channel and a mobility management channel.

[0061] This application does not specifically limit the periodic measurement channel. For example, the periodic measurement channel can be configured to evaluate network performance based on a reference signal. For example, the reference signal can be one or more of the following: Channel State Information-Reference Signal (CSI-RS), Phase-tracking-Reference Signal (PT-RS), or Tracking Reference Signal (Tracking RS). In some examples, the configuration of the periodic measurement channel is not fixed. The configuration bandwidth of the periodic measurement channel can be larger.

[0062] This application does not impose specific limitations on the mobility management channel. For example, the mobility management channel can be used to evaluate network performance based on common pilots. Common pilots can also be understood as common reference signals (CRS). In some examples, the configuration of the CRS can be fixed.

[0063] The first control / data channel can also be referred to as the basic control / data channel. In some embodiments, the first control / data channel can be a broadband control / data channel based on a relatively narrowband bandwidth. For example, the first control / data channel has a lower capacity. Also, the first control / data channel has lower power consumption.

[0064] In some embodiments, the first control / data channel is based on Orthogonal Frequency-Division Multiplexing (OFDM) modulation. For example, the transmission and reception of the first control / data channel can be based on OFDM modulation. That is, the original information is encoded into a bit sequence through channel encoding and decoding, and these bit sequences are directly modulated onto modulation symbols. Finally, multiple modulation symbols are mapped onto the subcarriers of OFDM symbols.

[0065] In some embodiments, the detection of the first control / data channel can be based on a detection indication (or control / data detection indication) rather than blind detection. For example, the first control / data channel is associated with a first indication signal, which indicates whether the first control / data channel should be detected.

[0066] The embodiments of this application do not specifically limit the indication method of the first indication signal.

[0067] As an example, the first indication signal indicates whether the first control / data channel is detected based on a sequence indication. This sequence indication could be based on sequence selection, or it could be based on sequence encoding.

[0068] A sequence can be understood as a sequence that carries indicative information. For example, a sequence can be a complex (or vector) sequence and / or a real sequence. As an example, complex sequences include, but are not limited to, one or more of the following: Constant Amplitude Zero Auto-Correlation Sequence (CAZAC) sequence, Zaddoff-Chu (ZC) sequence. As yet another example, real sequences can include, but are not limited to, Pseudo-Noise Sequence (PN) sequence, Gold sequence, Maximum-Length Sequence (M) sequence, or Hadamard sequence.

[0069] In some embodiments, the first indication signal may be obtained based on a detection indication. The detection indication channel is based on sequence modulation. For example, the modulation method of the detection indication channel is to modulate the sequence carrying indication information onto one or more OFDM symbols to obtain the first indication signal. In other words, the first indication information is a signal determined by modulating the sequence onto OFDM symbols.

[0070] As another example, the first indication information is based on a waveform indicating whether a first control / data channel is detected. For example, different indication information corresponds to different waveforms, and the waveform corresponding to the first indication information indicates whether the first control / data channel is detected. In some embodiments, the waveform may be a waveform with low power consumption.

[0071] The second type of frequency unit can also be called a capacity frequency unit or capacity carrier. The second type of frequency unit is used to expand the communication functions of terminal equipment. For example, the second type of frequency unit is used to expand the throughput of terminal equipment, enabling it to have more diverse communication functions. For example, more diverse communication functions are the communication functions of terminal equipment conforming to the NR R15 / R16 standard.

[0072] One or more second-class frequency units are used to configure (or, can be understood as configuration information corresponding to one or more second-class frequency units being used to configure) one or more of the following: resources corresponding to the second-class frequency unit; uplink synchronization channels and / or downlink synchronization channels corresponding to the frequency position of the second-class frequency unit (or, the second-class frequency unit is associated with uplink synchronization channels and / or downlink synchronization channels).

[0073] The resources corresponding to the second type of frequency unit include one or more of the following: time-domain resources, frequency resources, spatial resources, and throughput. In other words, the definition of resources corresponding to the second type of frequency unit includes time dimension, frequency dimension, spatial dimension, and throughput dimension.

[0074] In some embodiments, throughput includes the throughput of the control channel, the throughput of the data channel, and the throughput of the measurement signal. That is, the throughput dimension includes a control throughput dimension, a data throughput dimension, and a measurement throughput dimension.

[0075] In some embodiments, the uplink and / or downlink synchronization channels corresponding to the frequency position (or frequency domain position) of the second type of frequency unit can be understood as fast calibration channels. These uplink and / or downlink synchronization channels are used for fast activation synchronization of the frequency unit. For example, these uplink and / or downlink synchronization channels may not require frequency scanning as in the initial access method; they can be understood as designated or dedicated uplink and / or downlink synchronization channels. For example, the uplink synchronization channel may utilize SRS signals for synchronization. Similarly, the downlink synchronization channel may utilize CSI-RS for synchronization.

[0076] As mentioned above, the configuration information may include configuration information corresponding to multiple second-type frequency units. In some embodiments, the configuration information corresponding to multiple second-type frequency units is used to configure different resource sets for the multiple second-type frequency units. That is, different second-type frequency units correspond to different resource sets.

[0077] The embodiments of this application do not impose specific limitations on the correspondence between the carriers (or cells) of the first type of frequency unit and the second type of frequency unit.

[0078] In one implementation, the first type of frequency unit and the second type of frequency unit correspond to the same first carrier or first cell. That is, the first type of frequency unit and the second type of frequency unit are on the same carrier or in the same cell.

[0079] The resources corresponding to the first type of frequency unit and the resources corresponding to the second type of frequency unit can correspond to specific resource locations within the same carrier (or cell). In other words, the resources corresponding to the first type of frequency unit correspond to a first resource location within the same carrier (or cell), and the resources corresponding to the second type of frequency unit correspond to a second resource location within the same carrier (or cell). The first resource location and the second resource location are different. In some embodiments, if there are multiple second-type frequency units, the resources corresponding to these multiple second-type frequency units also correspond to multiple different second resource locations within the same carrier (or cell).

[0080] In some embodiments, resource locations can be subdivided into different sets. For example, a particular resource location includes, but is not limited to, one or more of the following: a set of resource blocks (RBs) in frequency, a set of time slots in time, and a set of beam domains in space. By planning and allocating these different types of resource sets, the network can effectively manage communication with user equipment.

[0081] In some embodiments, the frequency range corresponding to the first type of frequency unit is lower than the frequency range corresponding to the second type of frequency unit. In other words, the resource corresponding to the first type of frequency unit is located at a low-frequency position within the carrier (or cell), while the resource corresponding to the second type of frequency unit is located at other positions within the carrier (or cell), where the frequency of the other positions is higher than the frequency of the low-frequency positions.

[0082] In some embodiments, the downlink synchronization channel of the first cell is located within the frequency range corresponding to the first type of frequency element. Alternatively, the resources corresponding to the first type of frequency element include the cell's downlink synchronization channel at low-frequency locations within the carrier (or cell).

[0083] As an example, as shown in Figure 5, the configuration information configures a base frequency unit, capacity frequency unit 1, and capacity frequency unit 2. These three units are located in different frequency ranges within a cell (or carrier) bandwidth, with the base frequency unit corresponding to a lower frequency range than the capacity frequency units 1 and 2. Furthermore, the base frequency unit and capacity frequency unit 1 are inactive, while capacity frequency unit 1 is inactive.

[0084] As another implementation, the first type of frequency unit and the second type of frequency unit correspond to different carriers (or cells). That is, the first type of frequency unit and the second type of frequency unit are on different carriers (or cells).

[0085] In this configuration, the resources corresponding to the first type of frequency unit correspond to the resource location of the first carrier (or the first cell), and the resources corresponding to the second type of frequency unit may correspond to the resource location of the second carrier (or the second cell). The first cell and the second cell are different. Alternatively, the frequency range of the carrier or cell corresponding to the first type of frequency unit is a first frequency range, and the frequency range of the carrier or cell corresponding to the second type of frequency unit is a second frequency range. The first frequency range and the second frequency range are different. In some embodiments, if there are multiple second-class frequency units, the resources corresponding to these multiple second-class frequency units correspond one-to-one to multiple carriers (or cells), and these multiple carriers (or cells) are different.

[0086] In some embodiments, resource locations can be subdivided into different sets. For example, a particular resource location includes, but is not limited to, one or more of the following: a set of resource blocks (RBs) in frequency, a set of time slots in time, and a set of beam domains in space. By planning and allocating these different types of resource sets, the network can effectively manage communication with user equipment.

[0087] In some embodiments, the frequency range of the carrier or cell corresponding to the first type of frequency unit is a first frequency range, and the frequency range of the carrier or cell corresponding to the second frequency unit is a second frequency range, wherein the first frequency range is lower than the second frequency range. Alternatively, the resources corresponding to the first type of frequency unit are on low-frequency carriers (or low-frequency cells), while the resources corresponding to the second type of frequency unit are on other carriers (or other cells), wherein the frequency of the other carriers (or other cells) is higher than the frequency of the low-frequency carriers (or low-frequency cells).

[0088] In some embodiments, the downlink synchronization channel of the first cell is located within the frequency range corresponding to the first type of frequency element. Alternatively, the resource corresponding to the first type of frequency element includes the downlink synchronization channel of that cell at a low-frequency location within its carrier (or cell).

[0089] As an example, as shown in Figure 6, the configuration information specifies a base frequency unit, capacity frequency unit 1, and capacity frequency unit 2. These correspond to cell 1, cell 2, and cell 3, respectively. The frequency of cell 1 is lower than that of cells 2 and 3. Furthermore, the states of the base frequency unit, capacity frequency unit 1, and capacity frequency unit 2 are: base frequency unit and capacity frequency unit 2 are active, while capacity frequency unit 1 is inactive.

[0090] In some embodiments, the terminal device supports multiple processing capabilities. A first processing capability corresponds to a first type of frequency unit, and other processing capabilities besides the first processing capability correspond to one or more second type of frequency units. That is, different processing capabilities correspond to different configuration parameters. The first processing capability can be the most basic processing capability, such as the processing capability of a zero-power terminal device or a wearable device. Other processing capabilities can be capabilities extended based on the first processing capability; for example, other processing capabilities are processing capabilities with increased bandwidth or throughput based on the first processing capability.

[0091] In some embodiments, the communication method further includes: the terminal device receiving indication information (or conversion instruction, switching instruction, expansion instruction, or reduction instruction) sent by the network device, the indication information being used to indicate the activation of the second type of frequency unit. In other words, when the terminal device initially connects to the network device, the terminal device can default to activating the first type of frequency unit and deactivate the second type of frequency unit. As the communication scenario changes, the terminal device may need to have greater processing power; in this case, the network device can send indication information to the terminal device to activate the second type of frequency unit.

[0092] As an example, the configuration information sent by the network device is used to configure a capacity frequency unit and a base frequency unit. In some embodiments, before receiving an indication message, the state of a capacity frequency unit and a base frequency unit can be state a in Figure 7, where the base frequency unit is active and the capacity frequency unit is dormant. After receiving the indication message, the state of a capacity frequency unit and a base frequency unit can be state b in Figure 7, where both the base frequency unit and the capacity frequency unit are active. Of course, in some embodiments, before receiving an indication message, the state of a capacity frequency unit and a base frequency unit can be state b in Figure 7, and after receiving the indication message, the state of a capacity frequency unit and a base frequency unit can be state a in Figure 7.

[0093] In some embodiments, after receiving the aforementioned indication information, the terminal device can complete the adjustment of configuration parameters within a certain time slot k. That is, the configuration information corresponding to the second type of frequency unit is activated in the k-th time unit after the indication information.
