Method for transmitting data packets using different frequency reuse factors
View Patent ↗A method and device for transmitting a data signal including a plurality of data packets from a base station to a radio device that perform acts of subdiving each data packet into at least a first data sub-packet and a second data sub-packet; transmitting simultaneously the first data sub-packet on a first portion of total resources, having a first reuse frequency factor, and the second data sub-packet on at least one second portion of total resources having second reuse factor, said first reuse factor being different from said second reuse factor.
1. A method for transmitting a data signal including a plurality of data packets from a base station to a radio device, said method comprising acts of:
subdividing each data packet into at least a first data sub-packet and a second data sub-packet; and
transmitting the first data sub-packet on a first portion of total resources, having a first reuse factor, and the second data sub-packet on at least one second portion of total resources having a second reuse factor, said first reuse factor being different from said second reuse factor.
2. The method of claim 1 , wherein the first data sub-packet and the second data sub-packet are transmitted simultaneously.
3. The method of claim 1 , wherein each portion of total resources comprises at least one of the following: a set of at least one sub-carrier frequency, a set of at least one time-slot, or a set of at least one code.
4. The method of claim 1 , wherein each portion of total resources is non-contiguous.
5. The method of claim 1 , wherein each portion of total resources is contiguous.
6. The method of claim 1 , wherein the first portion of total resources has a reuse factor of 1.
7. The method of claim 1 , wherein the reuse factor is at least one of a frequency reuse factor, a time-slot reuse factor, and a code reuse factor.
8. The method of claim 1 , wherein the first portion of total resources has a first size and the second portion of total resources has a second size, wherein the first and the second sizes are chosen so that the global link spectral efficiency equals T=BT 1 +(1−B)T 2, T 1 being the link spectral efficiency of the first total resource portion, and T 2 being the link spectral efficiency of the second total resource portion.
9. The method of claim 8 , wherein the value of B is between 0.4 and 0.6.
10. The method of claim 1 , wherein said data signal is at least one of the following: a broadcast channel signal, a signaling channel signal, a control channel signal, a multicast signal.
11. The method of claim 1 , further comprising an act of coding the data signal before subdividing into data packets.
12. The method of claim 1 , further comprising an act of adding a redundancy check to the data signal before subdividing into data packets.
13. The method of claim 1 , further the comprising an act of signaling a resource partition pattern to the receiver by the base station.
14. The method of claim 13 , wherein the resource partition pattern is signaled by means of at least one of a pattern of pilot symbols, a pattern of a signal provided for synchronization, a cell identity and a base station identity.
15. A method for receiving a data signal including at least one data packet at a radio device, said method comprising acts of:
receiving a first data sub-packet on a first portion of total resources having a first reuse factor;
receiving a second data sub-packet on a second portion of total resources, said second portion of total resources having a second reuse factor, said first reuse factor being different from said second reuse factor; and
combining the first and second data sub-packets into a data packet.
16. The method of claim 15 , further comprising an act of receiving a resource partition pattern information.
17. The method of claim 15 , further comprising an act of decoding each data packet after combining the sub-packets.
18. A base station for transmitting a data signal including at least one data packet, the base station comprising:
means for subdividing each data packet into at least a first data sub-packet and a second data sub-packet;
a first transmitter for transmitting the first data sub-packet on a first portion of total resources, having a first reuse factor, and
a second transmitter for transmitting the second data sub-packet on at least one second portion of total resources having a second reuse factor, said first reuse factor being different from said second reuse factor.
19. The base station of claim 18 , further comprising means for transmitting resource pattern partition information.
20. A radio device, for receiving a data signal including at least one data packet from a base station in a network, said radio device comprising:
means for receiving a first signal including a first sub-packet on a first resource portion, said first resource portion having a first reuse factor; and
means for receiving a second signal including a second sub-packet on a second resource portion, said second resource portion having a second reuse factor, the first reuse factor being different from the second reuse factor.
21. The radio device of claim 20 , further comprising means for receiving a resource partition pattern information.
22. The radio device of claim 20 , further comprising a decoder for decoding each data packet after combining the sub-packets.
