Abstract

A user equipment, a method for controlling the user equipment, and a network side device are provided in the present disclosure. The method includes transmitting broadcast-type signals and channels to the user equipment through a dedicated resource unit so that the user equipment can access a network; wherein the dedicated resource unit is only configured to transmit the broadcast-type signals and channels and is continuous in a frequency domain and a time domain. The present disclosure can control the user equipment to access the network.

First claim

What is claimed is:

transmitting broadcast-type signals and channels to the user equipment through a dedicated resource unit to make the user equipment access a network and use a preset broadcast reference signal for time and frequency offset tracking, wherein the broadcast-type signals and channels comprise a synchronization signal, a broadcast channel and the preset broadcast reference signal, and the preset broadcast reference signal is used for decoding the broadcast channel;
wherein the dedicated resource unit is only configured to transmit the broadcast-type signals and channels, and is continuous in a frequency domain and a time domain.

2. The method for controlling the user equipment according to claim 1 , wherein the dedicated resource unit comprises a subframe or a transmission time interval in the time domain.

3. The method for controlling the user equipment according to claim 1 , wherein a time domain position and a frequency domain position of the dedicated resource unit are a predefined time domain position and a predefined frequency domain position respectively.

4. The method for controlling the user equipment according to claim 1 , wherein transmitting the broadcast-type signals and channels to the user equipment comprises: transmitting the broadcast-type signals and channels to the user equipment according to a preset basic carrier configuration to make user equipments of different kinds can recognize the broadcast-type signals and channels.

5. The method for controlling the user equipment according to claim 4 , wherein the basic carrier configuration comprises: a subcarrier spacing and a cyclic prefix length.

6. The method for controlling the user equipment according to claim 1 , wherein transmitting the broadcast-type signals and channels through the dedicated resource unit comprises: transmitting the broadcast channel to the user equipment by using the preset broadcast reference signal.

7. The method for controlling the user equipment according to claim 1 , wherein transmitting the broadcast-type signals and channels to the user equipment through the dedicated resource unit comprises: transmitting the broadcast-type signals and channels repeatedly in a plurality of the dedicated resource unit of different time domain positions and/or different frequency domain positions.

8. The method for controlling the user equipment according to claim 1 , wherein the broadcast-type signals and channels comprise a plurality of signals and/or channels, and there is a sequence among the plurality of signals and/or channels located in a same dedicated resource unit in the time domain.

9. A method for controlling a user equipment, comprising:
receiving broadcast-type signals and channels from a network side through a dedicated resource unit, wherein the broadcast-type signals and channels comprise a synchronization signal, a broadcast channel and a preset broadcast reference signal; and
accessing a network through the broadcast-type signals and channels, and using the preset broadcast reference signal for time and frequency offset tracking and for decoding the broadcast channel;
wherein the dedicated resource unit is only configured to transmit the broadcast-type signals and channels, and is continuous in a frequency domain and a time domain, and the broadcast-type signals and channels comprise a synchronization signal and a broadcast channel.

10. The method for controlling the user equipment according to claim 9 , wherein the dedicated resource unit comprises a subframe or a transmission time interval in the time domain.

11. The method for controlling the user equipment according to claim 9 , wherein a time domain position and a frequency domain position of the dedicated resource unit are a predefined time domain position and a predefined frequency domain position respectively.

12. The method for controlling the user equipment according to claim 9 , wherein receiving the broadcast-type signals and channels from the network side through the dedicated resource unit comprises: receiving the broadcast-type signals and channels according to a preset basic carrier configuration.

13. The method for controlling the user equipment according to claim 12 , wherein the basic carrier configuration comprises a subcarrier spacing and a cyclic prefix length.

14. The method for controlling the user equipment according to claim 9 , wherein receiving the broadcast-type signals and channels from the network side through the dedicated resource unit comprises: receiving the broadcast channel by using the preset broadcast reference signal.

15. The method for controlling the user equipment according to claim 9 , wherein receiving the broadcast-type signals and channels from the network side through the dedicated resource unit comprises: receiving the broadcast-type signals and channels repeatedly from a plurality of the dedicated resource unit of different time domain positions and/or different frequency domain positions.

16. The method for controlling the user equipment according to claim 9 , wherein the broadcast-type signals and channels comprise a plurality of signals and/or channels, the plurality of signals and/or channels located in a same dedicated resource unit are independently encoded and modulated, and accessing the network through the broadcast-type signals and channels comprises demodulating and decoding the plurality of signals and/or channels located in the same dedicated resource unit independently.

17. The method for controlling the user equipment according to claim 9 , wherein the broadcast-type signals and channels comprise a plurality of signals and/or channels, and accessing the network through the broadcast-type signals and channels comprises: processing the plurality of signals and/or channels located in a same dedicated resource unit sequentially according to a sequence of the plurality of signals and/or channels located in the same dedicated resource unit in the time domain.

18. The method for controlling the user equipment according to claim 17 , wherein processing the plurality of signals and/or channels located in the same dedicated resource unit sequentially according to the sequence of the plurality of signals and/or channels located in the same dedicated resource unit in the time domain comprises:
searching the synchronization signal;
determining configuration of the broadcast channel based on the synchronization signal; and
detecting the broadcast channel.

19. The method for controlling the user equipment according to claim 9 , wherein the broadcast-type signals and channels comprise different kinds of broadcast-type signals and channels respectively corresponding to different kinds of user equipment, the dedicated resource unit is divided into a plurality of dedicated resource subunits according to the different kinds of user equipment, the different kinds of broadcast-type signals and channels are transmitted through the plurality of dedicated resource subunits, and each of the plurality of dedicated resource subunits is independently encoded and modulated; and
accessing the network through the broadcast-type signals and channels comprises decoding and demodulating each of the plurality of dedicated resource subunits independently.

20. The method for controlling the user equipment according to claim 9 , wherein the broadcast-type signals and channels comprise different kinds of broadcast-type signals and channels respectively corresponding to different
