[0065] According to the signaling format of the configuration signaling, multiple physical resource blocks are instructed to be configured on the uplink and downlink.

[0066] The method for configuring multiple physical resource blocks on the uplink and downlink provided by this embodiment will be described in detail below with reference to the drawings. see image 3 , which is a schematic flowchart of a method for configuring multiple physical resource b...

Embodiment 2

[0100] This embodiment provides a system for configuring multiple physical resource blocks in the uplink and downlink, and the configuration system is applied to the cellular narrowband Internet of Things (NB-IoT). It should be noted that it should be understood that the following division of multiple physical resource blocks in each module of the uplink and downlink configuration system is only a division of logical functions, and can be fully or partially integrated into a physical entity in actual implementation, or physical separate. And these modules can all be implemented in the form of software calling through processing elements; they can also all be implemented in hardware; some modules can also be implemented in the form of calling software through processing elements, and some modules can be implemented in hardware. For example, the x module may be a separately established processing element, or it may be integrated into a certain chip of the above-mentioned device ...

Embodiment 3

[0127] This embodiment provides a device, including: a processor, a memory, a transceiver, a communication interface, and a system bus; the memory and the communication interface are connected to the processor and the transceiver through the system bus and communicate with each other, and the memory is used to store a computer The program, the communication interface is used for communicating with other devices, the processor and the transceiver are used for running the computer program, so that the device executes each step of the method for configuring multiple physical resource blocks in the uplink and downlink as described above.

[0128] The system bus mentioned above may be a Peripheral Pomponent Interconnect (PCI for short) bus or an Extended Industry Standard Architecture (Extended Industry Standard Architecture, EISA for short) bus or the like. The system bus can be divided into address bus, data bus, control bus and so on. For ease of presentation, only one thick lin...

Abstract

The present invention provides a multi-physical resource block configuration method / system in an uplink and downlink, a medium, and a device, which are applied to the cellular narrowband Internet ofThings. The configuration method comprises the following steps: reading a signaling format of configuration signaling, wherein the signaling format of the configuration signaling comprises a switchingconfiguration signaling format and a hybrid configuration signaling format with a symmetric uplink and downlink configuration and an asymmetric configuration; indicating that the multi-physical resource block is configured on the uplink and downlink according to the signaling format of the configuration signaling. The multi-physical resource block configuration method / system in the uplink and downlink, the medium, and the device provided by the present invention can flexibly and efficiently switch between the symmetric configuration and the asymmetric configuration according to specific conditions when business volume change happens suddenly in multi-PRB operations, save signaling overhead and improve system performance.

Description

technical field [0001] The present invention belongs to the technical field of wireless communication, and relates to a configuration method and system, in particular to a method / system, medium and device for configuring multiple physical resource blocks in uplink and downlink. Background technique [0002] RAN#69 plenary session launched WI to study CIoT wireless access solutions to enhance indoor coverage, support a large number of low-throughput devices, low latency sensitivity, extremely low cost, low power consumption, and optimize network architecture, RAN#70 plenary session was launched The WI of NB-IoT is proposed, and it is proposed that NB-IoT needs to support three different deployment schemes: standalone operation, guard-band operation and in-band operation. [0003] The performance gain of frequency hopping between multiple 200kHz channels has been studied and the advantages of multiple 200kHz channel deployments are described in TR45.820. Frequency hopping amo...
