Method and apparatus for transport block signaling in a wireless communication system
User equipment determines a transport block size column indicator representative of a number of resource blocks based on a number of allocated resource blocks, an adjustment factor, and a limiting factor. The transport block size column indicator is determined by applying the adjustment factor to the number of allocated resource blocks and comparing a result of applying the adjustment factor to the number of allocated resource blocks to the limiting factor. The transport block size column indicator is selected as either the result or the limiting factor as the based on the comparison.
1. A wireless communication terminal comprising a processor configured to determine, based on an adjustment factor, a transport block size (TBS) column indicator representative of a number of resource blocks, wherein the adjustment factor is determined based on one or both of (i) a search-space within which downlink control information is received by the wireless communication terminal, and (ii) a control channel aggregation-level on which the downlink control information is received by the wireless communication terminal.
2. The terminal of claim 1 , wherein the processor determines the TBS column indicator based on the adjustment factor and a number of allocated resource blocks.
3. The terminal of claim 2 , wherein the processor determines the TBS column indicator by applying the adjustment factor to the number of allocated resource blocks.
4. The terminal of claim 3 , wherein the processor determines the TBS column indicator by comparing a result of applying the adjustment factor to the number of allocated resource blocks to a limiting factor, and selecting either the result or the limiting factor as the TBS column indicator based on the comparison.
5. The terminal of claim 1 , wherein the processor determines the TBS column indicator based on the adjustment factor and a limiting factor.
6. The terminal of claim 5 , wherein the limiting factor is a signaled limit resource block number.
7. The terminal of claim 1 , further comprising a transceiver.
8. The terminal of claim 1 , further comprising a memory storing a transport block size table.
9. The terminal of claim 1 , wherein the processor is further configured to communicate using the determined transport block size.
10. The terminal of claim 1 wherein the adjustment factor is greater than 1 and less than 2.
11. The terminal of claim 1 wherein the processor is further configured to determine the TBS column indicator based on the adjustment factor only if a resource allocation is received in a control channel that spans a limited frequency portion of a carrier and spans an entire subframe.
12. A method in a wireless communication terminal, the method comprising determining, based on an adjustment factor, a transport block size (TBS) column indicator representative of a number of resource blocks, wherein the adjustment factor is determined based on one or both of (i) a search-space within which downlink control information is received by the wireless communication terminal, and (ii) a control channel aggregation-level on which the downlink control information is received by the wireless communication terminal.
13. The method of claim 12 , wherein determining the TBS column indicator comprises determining the TBS column indicator based on the adjustment factor and a number of allocated resource blocks.
14. The method of claim 13 , wherein determining the TBS column indicator based on the adjustment factor and the number of allocated resource blocks comprises determining the TBS column indicator by applying the adjustment factor to the number of allocated resource blocks.
15. The method of claim 14 , wherein determining the TBS column indicator further comprises comparing a result of applying the adjustment factor to the number of allocated resource blocks to a limiting factor, and selecting either the result or the limiting factor as the TBS column indicator based on the comparison.
16. The method of claim 12 wherein determining the TBS column indicator based on the adjustment factor is performed only if a resource allocation is received in a control channel that spans a limited frequency portion of a carrier and spans an entire subframe.
17. A non-transitory computer-readable medium having stored thereon computer-readable instructions for implementing a method in a wireless communication terminal, the method comprising determining, based on an adjustment factor, a transport block size (TBS) column indicator representative of a number of resource blocks, wherein the adjustment factor is determined based on one or both of (i) a search-space within which downlink control information is received by the wireless communication terminal, and (ii) a control channel aggregation-level on which the downlink control information is received by the wireless communication terminal.
18. The medium of claim 17 , wherein determining the TBS column indicator comprises determining the TBS column indicator based on the adjustment factor and a number of allocated resource blocks.
19. The medium of claim 18 , wherein determining the TBS column indicator based on the adjustment factor and the number of allocated resource blocks comprises determining the TBS column indicator by applying the adjustment factor to the number of allocated resource blocks.
20. The medium of claim 19 , wherein determining the TBS column indicator further comprises comparing a result of applying the adjustment factor to the number of allocated resource blocks to a limiting factor, and selecting either the result or the limiting factor as the TBS column indicator based on the comparison.
