Abstract

A method and device for acquiring user equipment duplex mode information are disclosed by the present invention, wherein, the method includes: the user equipment establishes a radio resource control connection with a base station, and reports the user equipment duplex mode information when establishing the radio resource control connection. With the technical scheme provided in the embodiments of the present invention, the network side acquires the duplex mode of the user equipment.

Claims

1. A method for obtaining duplex mode information of a User Equipment, UE, comprising:

a base station configuring a plurality of different mutually orthogonal sets of Physical Random Access Channel, PRACH, resources respectively for UE in a first type of duplex mode and UE in a second type of duplex mode, wherein locations in time and frequency of the orthogonal sets of PRACH resources for UE in a first type of duplex mode are different from locations in time and frequency of the orthogonal sets of PRACH resources for UE in a second type of duplex mode;

the base station signaling configuration information comprising the locations in time and frequency of the configured plurality of different mutually orthogonal sets of PRACH channel resources to the UE in the first type of duplex mode and the UE in the second type of duplex mode in system broadcast;

the base station detecting a random access signal which a UE initiates after selecting one among the set of PRACH channel resources in compliance with the type of duplex mode of the UE upon knowledge of the configuration information; and

the base station determining the type of duplex mode of the UE according to the location in time and frequency of the PRACH channel resource of the detected random access signal initiated from the UE.

2. The method according to claim 1, wherein the base station configures the plurality of different mutually orthogonal sets of PRACH channel resources, over an uplink carrier enabling a hybrid access of the first type of duplex mode and the second type of duplex mode, respectively for the UE in the first type of duplex mode and the UE in the second type of duplex mode.

3. The method according to claim 1, wherein the plurality of different mutually orthogonal sets of PRACH channel resources are sets of PRACH channel resources comprising orthogonal resources in the time domain and/or orthogonal resources in the frequency domain.

4. The method according to claim 1, wherein the first type of duplex mode and the second type of duplex mode are two different types of duplex modes selected from a group consisted of FDD, TDD and half-duplex FDD.

5. The method according to claim 2, wherein the first type of duplex mode and the second type of duplex mode are two different types of duplex modes selected from a group consisted of FDD, TDD and half-duplex FDD.

6. The method according to claim 3, wherein the first type of duplex mode and the second type of duplex mode are two different types of duplex modes selected from a group consisted of FDD, TDD and half-duplex FDD.
