The present disclosure relates to the field of wireless communication technologies, and in particular to, bandwidth part configuration methods, bandwidth part configuration apparatuses and storage media.
In a new generation of communication technology, a terminal can work based on a bandwidth part (BWP). That is, the terminal does not need to monitor the whole bandwidth, but only needs to send and receive data on part of the system bandwidth. In a time division duplex (TDD) system, uplink and downlink data transmissions can share the same bandwidth part. Therefore, in order to reduce a delay of uplink and downlink switching, it is required that the downlink (DL) BWP and the uplink (UL) BWP have the same center frequency.
For a reduced capability (Redcap) terminal, the capability of the Redcap terminal can monitor a DL initial BWP. However, a traditional UL initial BWP may exceed a bandwidth monitored by the Redcap terminal. Based on this, in the related art, the UL initial BWP may be configured separately for the Redcap terminal based on the DL initial BWP frequency range, however, this will limit system scheduling and configuration, and further cause the traditional UL BWP being divided into multiple fragments, resulting in load imbalance.
In order to overcome the problems existing in the related art, the present disclosure provides bandwidth part configuration methods, bandwidth part configuration apparatuses and storage media.

It can be understood that the communication system including a network device and terminals shown in
It can be further understood that the wireless communication system of the embodiments of the present disclosure is a network providing wireless communication functions. The wireless communication system can adopt different 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 FDMA (SC-FDMA), carrier sense multiple access with collision avoidance, etc. According to factors such as capacity, rate, delay of different networks, networks can be divided into 2-Generation (2G) networks, 3G networks, 4G networks or future evolution networks, such as 5G networks, which can also be called new radio (NR) networks. For ease of description, the present disclosure sometimes refers to a wireless communication network simply as a network.
Furthermore, a network device involved in the present disclosure may also be referred to as a radio access network device. The wireless access network device may be: a base station, an evolved node B, a home base station, an access point (AP) in a wireless fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (TRP), a transmission and reception point (TRP), etc., and it may further be a gNodeB (gNB) in a NR system, or, it may further be a component or a part of devices that constitutes a base station, etc. When it is a vehicle to X (V2X) communication system, the network device can further be a vehicle-mounted device. It should be understood that in the embodiments of the present disclosure, there is no limitation on specific technologies and specific device forms adopted by the network device.
Furthermore, a terminal involved in the present disclosure, which may also be referred to as a terminal device, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc., is a device that provides voice and/or data connectivity to a user, e.g., the terminal may be a hand-held device, a vehicle-mounted device, etc., having wireless connectivity. At present, some examples of terminals are: mobile phones, pocket personal computers (PPCs), palmtop computers, personal digital assistant (PDA), notebook computers, tablet computers, wearable devices, or vehicle-mounted devices. In addition, when it is a vehicle to X (V2X) communication system, the terminal device can further be a vehicle-mounted device. It should be understood that the embodiments of the present disclosure do not limit specific technologies and specific device forms adopted by the terminal.
In the new generation of communication technology, a terminal can work based on a bandwidth part (BWP). That is, the terminal does not need to monitor the whole bandwidth, but only needs to send and receive data on part of the system bandwidth. In the time division duplex system, uplink and downlink data transmissions can share the same bandwidth part. Therefore, in order to reduce a delay of uplink and downlink switching, it is required that the DL BWP and the UL BWP have the same center frequency.
The vigorous development of the Internet of Things has brought many conveniences to human life and work. Machine type communication (MTC) and narrow band Internet of things (NB-IOT) technologies are typical representatives of the cellular IoT technology. At present, these technologies have been widely used in many fields such as smart cities (such as meter reading), smart agriculture (such as temperature and humidity information collection) and smart transportation (such as shared-bikes).
In the communication system, for low rate and high delay scenarios (e.g., meter reading, environmental monitoring and other scenes) in the IoT business, the related art proposes two major technologies, MTC and NB-IOT. At present, the NB-IOT technology can support a maximum rate of several hundred Kbps, and MTC can support a maximum rate of several Mbps. However, with the continuous development of IoT business (such as monitoring, smart home, wearable devices, and industrial sensor detection), a speed of tens to 100 Mbps is generally required, and requirements for delay are also increased. Therefore, in the communication system, MTC and NB-IoT may no longer meet the requirements of the current Internet of Things business. At the same time, on the other hand, MTC and NB-IOT technologies are generally deployed in basements, outdoors and other scenes where it is not easy to charge or replace batteries, so a terminal associated with MTC and NB-IOT technologies is limited by hardware, which leads to its coverage capacity is not as good as that of general wireless communication terminals. And due to the impact of the application environment, power saving of its equipment is also a characteristic of MTC and NB IoT technologies. Based on this situation, the requirement of designing another new user equipment in 5G NR to cover this mid-range IoT device has begun to be proposed. In a current 3rd Generation Partnership Project (3GPP) standardization, this new terminal type is called a reduced capability (Redcap) terminal or NR-lite for short. A bandwidth configured for a Redcap terminal is relatively small.
In the Redcap terminal, a capability of the Redcap terminal is that a bandwidth monitoring capability of the Redcap terminal is 20 MHz for radio frequency (RF) 1, and for a downlink channel, an initial BWP is configured for the Redcap terminal separately. It may be implemented in different ways.
In an implementation, an original DL initial BWP is still monitored according to a capability of the Redcap terminal to monitor DL initial BWP. The UL initial BWP can be referred to
Based on the problems involved in the above embodiments, the present disclosure provides a BWP configuration method. By configuring different BWP pairs. Where each BWP pair includes a DL initial BWP and a UL initial BWP, moreover, if a downlink BWP and an uplink BWP in one of the BWP pairs may have a same center frequency point, a downlink BWP and an uplink BWP in the other BWP pair may have different center frequency points. Thereby ensuring flexibility in BWP configuration and avoiding splitting the uplink BWP.
The technical solution provided by the embodiments of the present disclosure can include the following beneficial effects: by configuring at least two BWP pairs, and the at least two BWP pairs are asymmetric BWP pairs, a situation of dividing BWP is avoided, and the flexibility of BWP configuration can be ensured.

The terminal may determine at least one of the first BWP pair or the second BWP pair according to configurations of network side devices.
According to the bandwidth part configuration method provided by the embodiments of the present disclosure, at least two BWP pairs are configured, and the center frequency points of the two BWPs in at least one BWP pair are different.

It can be further understood that “plurality” in the present disclosure means two or more, and that other quantifiers are similar. “And/or”, which describes the relationship of related objects, means that there can be three kinds of relationships, for example, A and/or B, which can mean that A exists alone, A and B exist together, and B exists alone. The character “/” generally indicates that the associated object is an “or” relationship. Singular forms of “a”, “said”, and “the” are also intended to include majority forms, unless the context clearly indicates otherwise.
It can be further understood that the terms “first”, “second”, etc. may be used to describe various information, but this information should not be limited to these terms. These terms are used only to distinguish the same type of information from one another and do not indicate a specific order or degree of importance. In fact, expressions such as “first” and “second” can be used interchangeably. For example, without departing from the scope of the present disclosure, first information can also be called second information, and similarly, the second information can also be called the first information.
