Abstract

Aspects include detecting, by a user equipment, an interference pattern that interferes with a transmission in a plurality of first time slots. Further included is determining a blanking pattern based on the temporal overlap between the interference pattern and the first time slots, and determining a partial time slot format for each partially overlapped one of the first time slots, wherein each partial time slot format includes code and pilot information from a non-overlapped section of each overlapped one of the first time slots. Additionally included is determining a code rate for each partial time slot based on each partial time slot format, determining a power boost for each partial time slot based on each code rate, and transmitting information in each partial time slot according to each partial time slot format and each corresponding code rate and at a transmit power associated with the corresponding power boost.

detecting, by a user equipment, an interference pattern that interferes with a transmission in a plurality of first time slots on an uplink channel, wherein the interference pattern occupies a plurality of second time slots and wherein at least one of the plurality of second time slots temporally overlaps one of the plurality of first time slots; determining a blanking pattern based on the temporal overlap between the plurality of first time slots and the plurality of second time slots; determining a partial time slot format for each of the plurality of first time slots determined to partially overlap with one of the plurality of second time slots, wherein each partial time slot format includes code information and pilot information from a non-overlapped section of each overlapped one of the plurality of first time slots; determining a code rate for each partial time slot based on each partial time slot format; determining a power boost for each partial time slot based on each code rate; and transmitting information in each partial time slot according to each partial time slot format and each corresponding code rate and at a transmit power associated with the corresponding power boost.

2 . The method of claim 1 , wherein each partial time slot format is based on an amount by which a respective one of the plurality of second time slots overlaps a respective one of the plurality of first time slots.

3 . The method of claim 1 , wherein the blanking pattern includes a partial time slot and at least one of a full slot and a blanked out slot, wherein the full slot includes one of the first time slots that does not overlap with one of the second time slots, and wherein the blanked out slot includes one of the first time slots that fully overlaps with one of the second time slots.

4 . The method of claim 1 , wherein each of the plurality of first time slots includes a first data field, a first control field configured to carry the control information, a pilot field configured to carry the pilot information, a second control field configured to carry the control information, and a second data field.

5 . The method of claim 4 , wherein the partial time slot format is configured to permit transmission of data from the first control field, the pilot field, the second control field, the second data field, and a segment of the first data field when at least one of the plurality of second time slots partially overlaps the first data field.

6 . The method of claim 4 , wherein the partial time slot format is configured to permit transmission of data from the second control field, the second data field, and a portion of the pilot field when at least one of the plurality of second time slots overlaps the first data field, the first control field, and a segment of the pilot field.

7 . The method of claim 4 , wherein the partial time slot format is configured to permit transmission of data from the first data field, first control field, the pilot field, the second control field, and a segment of the second data field when at least one of the plurality of second time slots partially overlaps the second data field.

8 . The method of claim 1 , further comprising signaling, to a network, user equipment (UE) capability information including an indication of a capability to support the partial time slot format.

9 . The method of claim 8 , wherein the power boost is configured to increase a transmission power of the partial time slot.

10 . The method of claim 1 , wherein the first time slot is a Global System for Mobile Communications (GSM) time slot.

11 . The method of claim 1 , wherein the second time slot is a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) time slot.

12 . The method of claim 1 , wherein determining the blanking pattern further comprises determining where the plurality of second time slots temporally overlap with the plurality of first time slots.

13 . The method of claim 1 , wherein the interference pattern is generated by the user equipment.

14 . The method of claim 1 , wherein the interference pattern is generated by an external signal source.

15 . An apparatus for wireless communication, comprising:
an interference detector configured to detect an interference pattern that interferes with a transmission in a plurality of first time slots on an uplink channel, wherein the interference pattern occupies a plurality of second time slots and wherein at least one of the plurality of second time slots temporally overlaps one of the plurality of first time slots; a blanking pattern determiner configured to determine a blanking pattern based on the temporal overlap between the plurality of first time slots and the plurality of second time slots; a partial slot format determiner configured to determine a partial time slot format for each of the plurality of first time slots determined to partially overlap with one of the plurality of second time slots, wherein each partial time slot format includes code information and pilot information from a non-overlapped section of each overlapped one of the plurality of first time slots; a code rate determiner configured to determine a code rate for each partial time slot based on each partial time slot format; a power boost determiner configured to determine a power boost for each partial time slot based on each code rate; and a transmitting component configured to transmit information in each partial time slot according to each partial time slot format and each corresponding code rate and at a transmit power associated with the corresponding power boost.
