Abstract

A small cell communication system and an operating method thereof are provided. The small cell communication system comprises a base station and a mobile device. The base station is configured to determine a reference signal pattern from a plurality of reference signal patterns, determine a physical resource block (PRB) bundling size corresponding to the reference signal pattern and transmit a signal with the PRB bundling size and the reference signal pattern. The mobile device is configured to receive the signal and perform channel estimation according to the PRB bundling size and the reference signal pattern. The operating method is applied to the small cell communication system to implement the aforesaid operations.

Claims

1. A small cell communication system, comprising:

a base station, configured to determine a reference signal pattern from a plurality of reference signal patterns, determine a physical resource block (PRB) bundling size corresponding to the reference signal pattern and transmit a signal with the PRB bundling size and the reference signal pattern; and

a mobile device, configured to receive the signal and perform channel estimation according to the PRB bundling size and the reference signal pattern.

2. The small cell communication system as claimed in claim 1, wherein the reference signal pattern indicates the amount of reference signals in one PRB and the PRB bundling size is at least one PRB;

and wherein the less the reference signal is used in one PRB, the more the PRB is bundled.

3. The small cell communication system as claimed in claim 1, wherein the reference signal pattern indicates the amount of reference signals in one PRB and the PRB bundling size is at least two PRBs;

and wherein the less the reference signal is used in one PRB, the more the PRB is bundled.

4. The small cell communication system as claimed in claim 1, wherein the reference signal pattern indicates the amount of reference signals in one PRB and the PRB bundling size is at least one PRB;

and wherein the more the reference signal is used in one PRB, the less the PRB is bundled.

5. The small cell communication system as claimed in claim 1, wherein the reference signal pattern indicates the amount of reference signals in one PRB and the PRB bundling size is at least two PRBs;

and wherein the more the reference signal is used in one PRB, the less the PRB is bundled.

6. The small cell communication system as claimed in claim 1, wherein the reference signal pattern indicates the distribution of reference signals and the PRB bundling size is determined according to the distribution of reference signals.

7. The small cell communication system as claimed in claim 1, wherein the mobile device further executes channel interpolation according to the reference signal pattern and the PRB bundling size to perform the channel estimation.

8. An operating method for a small cell communication system, the small cell communication system comprising a base station and a mobile device, the operating method comprising the following steps:

determining a reference signal pattern from a plurality of reference signal patterns by the base station;

determining a physical resource block (PRB) bundling size corresponding to the reference signal pattern by the base station;

transmitting a signal with the PRB bundling size and the reference signal pattern by the base station;

receiving the signal by the mobile device; and

9. The operating method as claimed in claim 8, wherein the reference signal pattern indicates the amount of reference signals in one PRB and the PRB bundling size is at least one PRB;

and wherein the less the reference signal is used in one PRB, the more the PRB is bundled.

10. The operating method as claimed in claim 8, wherein the reference signal pattern indicates the amount of reference signals in one PRB and the PRB bundling size is at least two PRBs;

and wherein the less the reference signal is used in one PRB, the more the PRB is bundled.

11. The operating method as claimed in claim 8, wherein the reference signal pattern indicates the amount of reference signals in one PRB and the PRB bundling size is at least one PRB;

and wherein the more the reference signal is used in one PRB, the less the PRB is bundled.

12. The operating method as claimed in claim 8, wherein the reference signal pattern indicates the amount of reference signals in one PRB and the PRB bundling size is at least two PRBs;

and wherein the more the reference signal is used in one PRB, the less the PRB is bundled.

13. The operating method as claimed in claim 8, wherein the reference signal pattern indicates the distribution of reference signals and the PRB bundling size is determined according to the distribution of reference signals.
