Abstract: Mechanisms may be used for aggregating acknowledgement (ACK), block ACK (BA) and/or short packets transmissions for multi-user (MU) wireless communication systems. Aggregation mechanisms may be used for uplink (UL) and/or downlink (DL) orthogonal frequency division multiple access (OFDMA), and/or UL/DL multiple-user multiple input multiple output (MU-MIMO) transmissions, for example. Multi-user short packets may be aggregated and/or simultaneously transmitted for DL, UL, or peer-to-peer (P2P) transmissions.

Abstract: Systems and methods are disclosed for providing efficient downlink Hybrid Automatic Request (HARQ) feedback. In some embodiments, a method of operation of a wireless device in a cellular communications system comprises receiving a downlink control information message comprising a HARQ feedback buffer index and storing a downlink HARQ feedback flag in a position within a HARQ feedback buffer that corresponds to the HARQ feedback buffer index. In this manner, multiple downlink HARQ feedback flags can be stored in the HARQ feedback buffer and subsequently transmitted to a network node in an efficient manner.

Abstract: Feedback determined for a plurality of subframes within a time window in a time division duplex system is bundled into at least two sets of feedback information based on differently timed bundling windows defined based on subframe types. When feedback associated with the plurality of subframes is received, possible errors in the subframes is determined based on the at least two sets of feedback information.

Abstract: A base station (103) assigns a set of mobile stations (101) to a group wherein the group will share a set of radio resources (770). A shared control channel information element (501) is sent to the group of mobile stations (101) and provides a bitmap having fields for group ordering (511), resource allocations (530), continuation resources (540) for HARQ, and an ordering pattern (513). If a mobile station requires retransmission it will access the resources indicated by the continuation resources field (54) in order to receive data. The HARQ blocks may be assigned to a mobile station based upon an index (601) which may correspond to the mobile station vocoder rate. Further, HARQ subgroups may be defined to associate subgroups of mobile stations with specific HARQ transmission opportunities on the super-frame and allocated by a rotating bitmap.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus groups subframes of a time division duplex (TDD) configuration of a serving cell into a set of anchor subframes and a set of non-anchor subframes. The apparatus also separately bundles positive acknowledgements (ACKs) and/or negative acknowledgements (NACKs) of the anchor subframes, and ACKs and/or NACKs of the non-anchor subframes.

Abstract: The apparatus improves HD-FDD data transmission rates, e.g., for eMTC by using a self subframe scheduling PDSCH that overlaps a M-PDCCH transmission in time. The apparatus may communicate using ACK(s)/NACK(s) for multiple HARQs that are bundled and/or multiplexed within a subframe in order to increase a number of HARQs.

Abstract: In a terminal, a control unit transmits a bundle response signal using a resource in a basic region of an uplink control channel in an uplink unit band of a unit band group when no error is detected in each of a plurality of pieces of downlink data of the unit band group, the uplink control channel in the uplink unit band being associated with a downlink control channel in a basic unit band that is a downlink unit band in which a broadcast channel signal including information relating to the uplink unit band is transmitted, and the control unit transmits the bundle response signal using a resource in an additional region of the uplink control channel when an error is detected in each of the plurality of pieces of downlink data.

Abstract: The present invention relates generally to communication networks and more specifically to methods and devices for data communication over a communication network. A method according to the invention comprises, at a transmitting node: obtaining a plurality of frames including first-type frames associated with an acknowledgment policy requiring acknowledgment and second-type frames associated with an acknowledgment policy requiring no acknowledgment; aggregating the frames of the obtained plurality of frames into an aggregated frame including at least one leading frame of second type and frames subsequent thereto, in an order depending on their associated acknowledgment policies; sending the aggregated frame to a receiving node; and sending an acknowledgment request frame to the receiving node to request it to acknowledge receipt of only subsequent frames of the aggregated frame. Such data communication scheme is liable to reduce bandwidth waste and head-of-line blocking and thus latency, compared to known scheme.

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.

Abstract: Disclosed are a method and an apparatus for indicating a frame type using a physical layer convergence protocol header. A method for determining a frame type using a PLCP header may comprise: a step of demodulating a frame type contained in an SIG of the PLCP header so as to acquire information indicating a physical service data unit (PSDU) of a frame; and a step of acquiring frame information required for demodulating the frame contained in the SIG dependently on the information indicating PSDU. Thus, unnecessary information may not be additionally demodulated to thereby improve demodulation efficiency and reduce unnecessary power consumption.
