Description

Technology Field

[0001] The present disclosure relates to the field of wireless communication technology, and in particular to a method for setting a bandwidth portion, a device for setting a bandwidth portion, and a storage medium. Background Technology

[0002] In next-generation communication technology, terminals can operate based on a bandwidth part (BOP). That is, terminals do not need to monitor the entire bandwidth and can perform data transmission and reception using only a portion of the system bandwidth. In a Time Division Duplexing (TDD) system, the transmission and reception of uplink and downlink data can share the same bandwidth part. Therefore, to reduce uplink-downlink switching delays, the downlink (DL) BWP and the uplink BWP are required to have the same center frequency point.

[0003] In a reduced capability (Redcap) terminal, the Redcap terminal's capability can monitor the initial downlink bandwidth portion (DLinitial BWP). However, the initial uplink bandwidth portion (ULinitial BWP) may exceed the bandwidth range monitored by the Redcap terminal. Accordingly, in the relevant technology, if the ULinitial BWP is set independently for the Redcap terminal based on the frequency point of the DLinitial BWP, the scheduling and configuration of the system are limited. If independent DLinitial BWP and ULinitial BWP are set for the Redcap terminal, additional system message overhead increases.

[0058] An exemplary embodiment is described in detail below. Such examples are illustrated in the drawings, and where the following description relates to the drawings, the same numbers in different drawings indicate the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiment are not representative of all embodiments consistent with the present disclosure. On the other hand, they are merely examples of devices and methods consistent with some aspects of the present disclosure as described in detail in the appended claims.

[0059] FIG. 1 is a communication system architecture diagram of a network device and a terminal according to an exemplary embodiment. The BWP configuration method provided by the present disclosure can be applied to the communication system architecture diagram shown in FIG. 1. As shown in FIG. 1, the network-side device can transmit signaling based on the architecture shown in FIG. 1.

[0060] The communication system of the network device and terminal illustrated in FIG. 1 is described merely as an example, and it can be understood that the wireless communication system may include other network devices, such as core network devices, wireless relay devices, and wireless return devices, which are not shown in FIG. 1. The embodiments of the present disclosure do not limit the number of network devices and terminals included in the wireless communication system.

[0061] The wireless communication system of the embodiments of the present disclosure is a network that provides wireless communication functions. It can be understood that the wireless communication system may use other communication technologies such as Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single Carrier Frequency Division Multiple Access (SC-FDMA), and Carrier Sense Multiple Access with Collision Avoidance. Depending on factors such as capacity, speed, and latency of different networks, networks can be classified into future evolutionary networks such as 2G networks, 3G networks, 4G networks, or 5G networks; for example, a 5G network may also be referred to as a New Radio (NR) network. For ease of explanation, the present disclosure may abbreviate a wireless communication network as a network.

[0062] Furthermore, network devices related to the present disclosure may also be referred to as wireless access network devices. Such wireless access network devices may be base stations, evolved node B (base stations), home base stations, access points (APs) in wireless fidelity (WIFI) systems, wireless relay nodes, wireless return nodes, transmission points (TPs), or transmission and reception points (TRPs). They may constitute components or parts of devices of gNBs or base stations in NR systems. In the case of a vehicle network (V2X) communication system, the network device may be a vehicle-mounted device. It should be understood that the embodiments of the present disclosure are not limited to specific technologies and specific device forms used by the network device.

[0063] Furthermore, the terminal related to the present disclosure may be referred to as a terminal device, User Equipment (UE), Mobile Station (MS), Mobile Terminal (MT), etc., and is a device that provides voice and / or data connectivity to a user. For example, the terminal may be a handheld device with wireless connectivity capabilities, a vehicle-mounted device, etc. Currently, some examples of terminals include smartphones (Mobile Phones), Pocket Personal Computers (PPCs), portable computers, Personal Digital Assistants (PDAs), laptops, tablets, wearable devices, or vehicle-mounted devices. Additionally, in the case of a Vehicle-to-Vehicle (V2X) communication system, the terminal device may be a vehicle-mounted device. It should be understood that the embodiments of the present disclosure do not limit the specific technology and specific device form used by the terminal.

[0064] In next-generation communication technology, terminals can operate based on a bandwidth part (BOP). That is, terminals do not need to monitor the entire bandwidth and can perform data transmission and reception using a portion of the system bandwidth. In a Time Division Duplexing (TDD) system, the transmission and reception of uplink and downlink data can share the same bandwidth part. Therefore, to reduce uplink-downlink switching delays, it is required that the Downlink (DL) BWP and the Uplink BWP have the same center frequency point.

[0065] The active development of the Internet of Things is bringing many conveniences to human life and work. Among them, Machine Type Communication (MTC) and Narrowband Internet of Things (NB-IoT) are typical and representative examples of cellular Internet of Things technology. Currently, these technologies are widely used in many fields, such as smart cities (e.g., meter reading), smart agriculture (e.g., collection of information such as temperature and humidity), and smart transportation (e.g., shared bicycles).

[0066] In communication systems, regarding Internet of Things (IoT) services, two technologies—MTC and NB-IoT—are provided for scenarios requiring low-rate high coverage (e.g., meter reading, environmental monitoring). Currently, NB-IoT technology can support rates up to several hundred kJ, while MTC can support rates up to several megabytes. However, with the advancement of IoT services (e.g., monitoring control, smart homes, wearable devices, industrial sensor detection), rates of tens to hundreds of megabytes are generally required, and latency requirements are also increasing relatively. Consequently, in communication systems, neither MTC nor NB-IoT can satisfy the demands of current IoT services. At the same time, since MTC and NB-IoT are typically deployed in environments such as basements or outdoors where charging or battery replacement is difficult, terminals related to these technologies are subject to hardware limitations, resulting in coverage capabilities that lag behind those of general wireless communication terminals. In addition, power saving of the device is a characteristic of both MTC and NB-IoT technologies due to the influence of the application environment. Based on this situation, demands are beginning to be submitted to redesign new user devices to cover these mid-range IoT devices in 5G NR. In current 3GPP (3rd Generation Partnership Project) standardization, this type of new terminal is abbreviated as a Reduced Capability (Redcap) terminal or NR-lite (a new air interface for the simplified version). The bandwidth set by Redcap terminals is relatively small.

[0067] In the Redcap terminal, the capability of the Redcap terminal is Radio Frequency (RF) 1, the bandwidth monitoring capability of the Redcap terminal is 20 MHz, and for the downlink channel, the Redcap terminal sets the initial BWP alone. Other methods of implementation may be used.

[0068] In the implementation method, the ability to monitor the initial downlink BWP based on the Redcap terminal still monitors the original initial downlink BWP. For the initial uplink BWP, refer to FIG. 2, which is a schematic diagram for setting a standalone initial uplink BWP according to an exemplary embodiment. As shown in FIG. 2, since the initial uplink BWP may exceed the range of the terminal's ability to monitor bandwidth, a standalone initial uplink BWP is set based on the bandwidth of the initial downlink BWP. In this case, it becomes a constraint on system scheduling and configuration.

[0069] In the implementation method, independent initial downlink BWP and initial uplink BWP are established for the Redcap terminal, but additional system message overhead increases.

[0070] Based on the problems related to the above embodiments, the present disclosure provides a method for setting BWPs. By setting different BWP pairs and including an initial downlink BWP and an initial uplink BWP in each BWP pair, flexibility in BWP setting is ensured and system overhead is reduced.

[0073] In an embodiment of the present disclosure, a first initial BWP pair comprises a first initial uplink BWP and a first initial downlink BWP, and a second initial BWP pair comprises a second initial uplink BWP and a second initial downlink BWP. The first initial uplink BWP of the first initial BWP pair may be smaller than the second initial uplink BWP of the second initial BWP pair, and the first initial downlink BWP may be equal to the second initial downlink BWP. The first initial downlink BWP may be different from the second initial downlink BWP.

[0074] In an embodiment of the present disclosure, the bandwidth of the initial uplink BWP and the initial downlink BWP of the first initial BWP pair is less than or equal to the first threshold.

[0075] In some embodiments of the present disclosure, the terminal includes a first type of terminal and a second type of terminal, the first type of terminal may be a terminal with relatively low capability, e.g., a Redcap terminal, and the second type of terminal may be a terminal with relatively high capability, e.g., a normal terminal. The first threshold may be determined according to the bandwidth supported by the type of the first terminal. Among these, the capability of the first type of terminal is lower than the capability of the second type of terminal. For example, the terminal bandwidth of the first type of terminal is smaller than the terminal bandwidth of the second type of terminal.

[0076] In an exemplary embodiment of the present disclosure, a network-side device supports setting at least two initial BWP pairs, and the first initial BWP pair does not exceed the bandwidth of a first type terminal. The second initial BWP pair may be set based on the bandwidth of a second type terminal. Among these, the first initial BWP pair and the second initial BWP pair may carry different information.

[0089] In some embodiments of the present disclosure, the information of the first type may be a random access message of the terminal of the first type. For example, the first initial downlink BWP may carry messages during the random access process, such as a Random Access Response (RAR) and a Random Access Message 4 (Msg. 4). The information of the second type may be a system message, for example, the second initial downlink BWP may carry a Synchronization Signal and PB CH Block (SSB), Remaining Minimum System Information (RMSI), a paging message, etc. The terminal of the first type and the terminal of the second type must monitor the second initial BWP pair.

[0090] In some embodiments of the present disclosure, the information of the second type further includes a message during the terminal random access process of the second type and configuration information of the first initial BWP pair. Among these, the configuration information of the first initial BWP pair may have an RSMI carrying. The terminal may determine the configuration information of the first initial BWP pair based on the RSMI in the second initial BWP pair.

[0092] In step S31, in response to the terminal being a terminal of type 1, during the process of accessing the network, the configuration information of the first initial BWP pair is determined based on the information of type 2.

[0093] In an embodiment of the present disclosure, when a terminal accesses a network, the terminal monitors a second initial BWP pair and determines second type information carried by the second initial BWP pair. It performs measurement of an SSB, synchronization, and reading of a system message in the second initial downlink BWP.
