Abstract: Techniques for bundling acknowledgement (ACK) information in a wireless communication system are described. In one design, a user equipment (UE) may receive multiple codewords in at least one downlink subframe. The UE may decode the multiple codewords and determine an ACK or a negative acknowledgement (NACK) for each codeword based on decoding result. The UE may bundle the ACKs and NACKs for the multiple codewords to obtain bundled ACK information. In one design, the UE may generate (i) a bundled ACK if ACKs are obtained for all codewords or (ii) a bundled NACK if a NACK is obtained for any codeword. The UE may send the bundled ACK information as feedback for the multiple codewords. The UE may receive retransmissions of the multiple codewords if a bundled NACK is sent and may receive new codewords if a bundled ACK is sent.

Abstract: A device includes a receiver, a buffer, and an analyzer. The receiver is configured to receive packets that correspond to at least a subset of a sequence of packets and that include error correction data. The error correction data of a first packet of the packets includes a partial copy of a second packet. The buffer is configured to store the packets. The analyzer is configured to determine whether a first particular packet of the sequence is missing from the buffer, to determine whether a partial copy of the first particular packet is stored in the buffer as error correction data in a second particular packet, to update a value based at least in part on whether the first particular packet is missing from the buffer and the partial copy of the first particular packet is stored in the buffer, and to adjust an error recovery parameter based at least in part on the value.

Abstract: Systems and methods for utilizing paging group IDs and paging indicators are disclosed for PDCCH and PDSCH transmissions to mobile terminals in a mobile communication system. By use of the paging group IDs and paging indicators, various groups of mobile terminals, including subsets of those groups can be paged with reduced decoding requirements. Nesting of the grouping is exploited and packing of the PDCCH frame to accomplish efficient use is described.

Abstract: Methods, systems, and devices are described for dynamically adjusting a ZeroCorrelationZoneConfig (Ncs) parameter of a base station. An initial Ncs parameter is set for the base station. A determination is made as to whether a count of timing synchronization failures between a mobile device and the base station exceeds a threshold. A determination is also made as to whether the timing synchronization failures correspond to a predetermined range of timing advanced (TA) estimated values. Upon determining that the count of timing synchronization failures exceeds the threshold and that the failures correspond to the predetermined range of TA estimated values, the initial Ncs parameter is dynamically adjusted.
