Time domain resource configuration method and access network equipment

Abstract

The embodiment of the invention discloses a time domain resource configuration method and access network equipment, which are used for realizing UE-level semi-static or dynamic configuration GP and flexible and dynamic uplink and downlink resource allocation and effectively utilizing resources. The method provided by the embodiment of the invention comprises the following steps: determining a guard interval GP resource required by terminal equipment, wherein the GP resource required by the terminal equipment is a GP resource required by uplink synchronization of the terminal equipment and access network equipment; and sending first time domain resource configuration information to the terminal equipment, wherein the first time domain resource configuration information indicates GP resources required by the terminal equipment.

Description

technical field [0001] The present application relates to the communication field, and in particular to a method for configuring time-domain resources and access network equipment. Background technique [0002] In a time division duplex (TDD) system, a guard period (GP, guard period) is a guard period set for uplink and downlink switching. If the downlink transmission system of the base station is sending signals while the uplink transmission system is receiving signals, since TDD uses uplink and downlink co-frequency transmission, the uplink transmission system will be seriously interfered. At the same time, from transmission to reception, the power of the transmitter does not disappear immediately, but there is a decline process, and it cannot work during this time; the same is true when changing from reception to transmission, the transmitter increases the power It also takes time, and it cannot work during this time. [0003] The length of GP can be configured. If conf...

If the downlink transmission system of the base station is sending signals while the uplink transmission system is receiving signals, since TDD uses uplink and downlink transmission at the same frequency, the uplink transmission system will be severely interfered

At the same time, from transmission to reception, the power of the transmitter does not disappear immediately, but there is a decline process, and it cannot work during this time; the same is true when changing from reception to transmission, the transmitter increases the power It also takes time, and it cannot work during this time.
