Abstract
This invention concerns multiplexing in Long Term Evolution (LTE) and Long Term Evolution-Advanced (LTE-A) in Evolved Universal Terrestrial Radio Access Network (E-UTRAN) wireless telephony. Joint processing down link coordinated multi-point reference signaling includes combining resource signal types at a user equipment determining conflicts between resource signals of plural user equipment puncturing resource signals of other cell upon determining conflicts between resource signals of plural user equipment and transmitting non-punctured combined resource signals from a user equipment.

Claim
1. A method of processing down link coordinated multi-point reference signaling in a user equipment (UE), comprising: determining if coherent combining is selected for processing down link coordinated multi-point (COMP) reference signaling; determining if Time Division Multiplexing is selected when coherent combining is selected; avoiding Physical Downlink Shared Channel (PDSCH) resource element puncturing when Time Division Multiplexing is selected; avoiding making the UE aware of an active coordinated multi-point set when Time Division Multiplexing is selected; and using a user equipment specific reference signal for Physical Downlink Shared Channel (PDSCH) demod-RS when Time Division Multiplexing is selected.
2. The method of claim 1, further comprising:
performing Physical Downlink Shared Channel (PDSCH) resource element puncturing when Time Division Multiplexing is not selected;
making the UE aware of an active coordinated multi-point set when Time Division Multiplexing is not selected;
determining if Time Division Multiplexing is selected when coherent combining is selected; and
reusing a cell specific reference signal for Physical Downlink Shared Channel (PDSCH) demod-RS when Time Division Multiplexing is not selected.
3. The method of claim 1, further comprising:
performing Physical Downlink Shared Channel (PDSCH) resource element puncturing when coherent combining is not selected;
making the UE aware of an active coordinated multi-point set when coherent combining is not selected;
determining if Time Division Multiplexing is selected when coherent combining is selected; and
reusing an R8 cell specific reference signal of a UE specific reference signal for Physical Downlink Shared Channel (PDSCH) demod-RS when Time Division Multiplexing is selected.
4. The method of claim 2, further comprising:
performing Physical Downlink Shared Channel (PDSCH) resource element puncturing when coherent combining is not selected;
making the UE aware of an active coordinated multi-point set when coherent combining is not selected;
determining if Time Division Multiplexing is selected when coherent combining is selected; and
reusing an R8 cell specific reference signal of a UE specific reference signal for Physical Downlink Shared Channel (PDSCH) demod-RS when Time Division Multiplexing is selected.
5. The method of claim 1, further comprising:
performing Physical Downlink Shared Channel (PDSCH) resource element puncturing when coherent combining is not selected;
making the UE aware of an active coordinated multi-point set when coherent combining is not selected;
determining if Time Division Multiplexing is selected when coherent combining is selected; and
reusing a cell specific reference signal for Physical Downlink Shared Channel (PDSCH) demod-RS when Time Division Multiplexing is selected.
6. The method of claim 2, further comprising;
performing Physical Downlink Shared Channel (PDSCH) resource element puncturing when coherent combining is not selected;
making the UE aware of an active coordinated multi-point set when coherent combining is not selected;
determining if Time Division Multiplexing is selected when coherent combining is selected; and
reusing a cell specific reference signal for Physical Downlink Shared Channel (PDSCH) demod-RS when Time Division Multiplexing is selected.
7. The method of claim 1, further comprising:
performing Physical Downlink Shared Channel (PDSCH) resource element puncturing when coherent combining is not selected;
making the UE aware of an active coordinated multi-point set when coherent combining is not selected;
determining if Time Division Multiplexing is selected when coherent combining is selected;
reusing an R8 cell specific reference signal of a UE specific reference signal for Physical Downlink Shared Channel (PDSCH) demod-RS when Time Division Multiplexing is selected; and
reusing a cell specific reference signal for Physical Downlink Shared Channel (PDSCH) demod-RS when Time Division Multiplexing is selected.
8. The method of claim 2, further comprising:
performing Physical Downlink Shared Channel (PDSCH) resource element puncturing when coherent combining is not selected;
making the UE aware of an active coordinated multi-point set when coherent combining is not selected;
