Abstract
The present invention provides a method for configuring a random access channel transmitting resource in a time division duplexing (TDD) mode and a device thereof. The method comprises generating configuration information for indicating a random access channel transmitting resource. The configuration information comprises period indicating information for indicating a configured period of the random access channel transmitting resource, and/or offset indicating information for indicating an offset of the random access channel transmitting resource in the configured period. The method further comprises transmitting the configuration information to user equipment (UE).
Claims3
A method performed by a user equipment, the method comprising:
- receiving Narrowband Physical Random Access Channel (NPRACH) configurations for Time Division Duplex (TDD), the NPRACH configurations including first information for indicating an NPRACH periodicity (P), with a value chosen from a set {80 ms, 160 ms, 320 ms, 640 ms, 1280 ms, 2560 ms, 5120 ms, 10240 ms}, and second information for indicating an NPRACH offset (O), in unit of radio frame;
- and
- transmitting an NPRACH based on the NPRACH configurations, wherein
- NPRACH starts in a radio frame nf fulfilling (nf-O) mod (P/10)=0.
A user equipment, comprising:
- receiving circuitry configured to receive Narrowband Physical Random Access Channel (NPRACH) configurations for Time Division Duplex (TDD), the NPRACH configurations including first information for indicating an NPRACH periodicity (P), with a value chosen from a set {80 ms, 160 ms, 320 ms, 640 ms, 1280 ms, 2560 ms, 5120 ms, 10240 ms}, and second information for indicating an NPRACH offset (O), in unit of radio frame;
- and
- transmitting circuitry configured to transmit an NPRACH based on the NPRACH configurations, wherein
- the NPRACH starts in a radio frame nf fulfilling (nf-O) mod (P/10)=0.
A base station, comprising:
- transmitting circuitry configured to transmit Narrowband Physical Random Access Channel (NPRACH) configurations for Time Division Duplex (TDD), the NPRACH configurations including first information for indicating an NPRACH periodicity (P), with a value chosen from a set {80 ms, 160 ms, 320 ms, 640 ms, 1280 ms, 2560 ms, 5120 ms, 10240 ms}, and second information for indicating an NPRACH offset (O), in unit of radio frame;
- and
- receiving circuitry configured to receive an NPRACH based on the NPRACH configurations, wherein
- NPRACH starts in a radio frame nf fulfilling (nf-O) mod (P/10)=0.
