Abstract
A resource allocation method, device and base station for when an LTE system in an unlicensed frequency band is running in TDD mode a dynamic uplink-downlink configuration, wherein, the method comprises: transmitting to a terminal indication information used to indicate a time-frequency resource occupied by a physical random access channel (PRACH), so as to enable the terminal to initiate a random access process via a corresponding time-frequency resource, wherein the indication information, when indicating a time-domain frequency occupied by the PRACH, only indicates the position of the first subframe occupied by the PRACH, and the first subframe is an uplink subframe or uplink pilot timeslot (UpPTS).
Claims20
A resource configuration method, comprising:
- transmitting, to a terminal, indication information used to indicate time-frequency resources occupied by a Physical Random Access Channel (PRACH), so as to enable the terminal to initiate a random access process through corresponding time-frequency resources, wherein, the method is applied when a Long Term Evolution (LTE) system operates on an unlicensed frequency band in a Time Division Duplexing (TDD) mode with a dynamic uplink/downlink configuration, and the indication information, when indicating time domain resources occupied by the PRACH, indicates only a position of a first subframe occupied by the PRACH, wherein the first subframe is an uplink subframe or an Uplink Pilot Timeslot (UpPTS).
A resource configuration device, comprising:
- a transmitting unit, configured to transmit indication information used to indicate time-frequency resources occupied by a Physical Random Access Channel (PRACH) to a terminal, so as to enable the terminal to initiate a random access process through corresponding time-frequency resources, wherein, the device is applied to when a Long Term Evolution (LTE) system operates on an unlicensed frequency band in a Time Division Duplexing (TDD) mode with a dynamic uplink/downlink configuration, and the indication information, when indicating time domain resources occupied by the PRACH, indicates only a position of a first subframe occupied by the PRACH, wherein the first subframe is an uplink subframe or an Uplink Pilot Timeslot (UpPTS).
