Abstract: A user equipment (UE) and base station may implement improved communication methods which enable a UE that is peak current limited to perform UL transmissions which are consistent with the UL timeline. A UE that is peak current limited may utilize a new form of distributed TTI (transmit time interval) bundling for improved uplink communication performance. In performing “distributed” TTI bundling, the UE may transmit a plurality of redundancy versions of first information to the base station, wherein the plurality of redundancy versions are transmitted in non-consecutive sub-frames with a periodicity of X ms. After the plurality of redundancy versions of first information are transmitted to the base station, the base station may provide a single acknowledge/negative acknowledge (ACK/NACK) to the UE. A method for dynamically generating and using a bundle size for TTI bundling is also disclosed.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may transmit feedback, such as hybrid automatic repeat request (HARQ) feedback for groups of code blocks rather than for an entire transport block or individual code blocks. The wireless device may transmit an acknowledgement (ACK) or negative-acknowledgement (NACK) to provide feedback for each code block group of a set of code block groups. An ACK may indicate that code blocks in a code block group were successfully decoded, and a NACK may indicate that at least one code block in a code block group was not successfully decoded. Wireless devices may support several techniques for grouping code blocks for feedback reporting to allow for efficient retransmissions and limited overhead. Different grouping schemes may be employed depending on system constraints, device capability, link conditions, or the like.

Abstract: A method and apparatus for resource allocation for half duplex frequency division duplexing in a wireless communication system is provided. Fixed or variable HARQ timing of greater than 5 subframes may be implemented. Acknowledgements for multiple downlink (uplink) transmissions can be bundled into a single acknowledgement transmitted on an uplink (downlink) control channel. Bundled acknowledgements for downlink transmissions may also be provided. Variable lead time cross subframe scheduling may be provided in which the number of subframes of delay between an uplink or downlink grant and the corresponding scheduled uplink or downlink transmission changes based on other scheduled events and/or half-duplex transceiver availability in the appropriate mode. The scheduling may select the earliest available subframe after a minimum delay. Uplink grant bundling may also be performed, in which multiple uplink grants are transmitted via a single grant indication.

Abstract: The present disclosure provides a method, a terminal device and a base station for transmitting feedback information, the method includes: receiving, by the terminal device, the plurality of data packets transmitted by the base station; if the terminal device determines that there is an unsuccessfully received data packet in the plurality of data packets, transmitting, by the terminal device, first feedback information to the base station, where the first feedback information is configured for feeding back for the receiving status of the plurality of data packets, and the first feedback information includes only negative acknowledgement (NACK) information for negatively acknowledging the unsuccessfully received data packet. Therefore the terminal device does not need to transmit specialized acknowledgement information to the base station for a successfully received data packet, thereby avoiding a waste of resources and improving the throughput of the communication system.

Abstract: Provided is a method of transmitting ACK/NACK in a TDD-based wireless communication system. The method includes: receiving M downlink subframes associated with an uplink subframe n in each of two serving cells; determining four candidate resources based on the M downlink subframes received in each of the two serving cells; and transmitting an ACK/NACK response for the M downlink subframes by using one resource selected from the four candidate resources in the uplink subframe n, wherein the two serving cells includes a first serving cell and a second serving cell, and wherein among the four candidate resources, a first resource and a second resource are associated with a PDSCH or a SPS release PDCCH for releasing semi-persistent scheduling received in the first serving cell, and a third resource and a fourth resources are associated with a PDSCH received in the second serving cell.
