Abstract

The invention discloses a method and a device for allocating physical resources. The method comprises the following steps: acquiring information of transmitting units in the physical resources, wherein the information of the transmitting units comprises types and combining manners of the transmitting units, the types of the transmitting units comprise uplink transmitting units and downlink transmitting units, and the combining manners comprise a manner of combining all uplink transmitting units, a manner of combining all downlink transmitting units or a manner of combining the uplink transmitting units and the downlink transmitting units; and allocating the resources in each transmitting unit according to a preset resource allocating rule, wherein the preset allocating rule is used for allocating resources spaced by different subcarriers in each transmitting unit. Through adoption of the method and the device, uplink and downlink resource allocation can be performed more flexibly; physical resources spaced by different subcarriers are coordinated; and different types of service data can be arranged conveniently.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of communications, and in particular, to a method and device for allocating physical resources. Background technique [0002] The 5G research topic Study on New Radio Access Technology was established in the 3GPP RAN 70 plenary meeting, and the research on 5G wireless air interface technology (NR for short) was officially started. The sub-carrier spacing is 15kHz or M*15kHz (wherein M=2^n, n is an integer) and passed the conclusion in RAN1 84bis. That is, multiple subcarrier spacings are supported in NR, which is different from LTE only supporting a single 15kHz subcarrier spacing. [0003] The interval between subcarriers in the physical resource block of Long Term Evolution (LTE) is fixed, 12 subcarriers in average, divided into 7 symbols of normal CP and 6 symbols of extended CP according to CP type. The LTE bandwidth is divided into several consecutive subcarriers in the frequency...
