WebA method and system to improve the link budget of a wireless system using fast Hybrid Automatic Repeat Request (HARQ) protocol. In one embodiment of the invention, the Medium Access Control (MAC) logic in a base station determines whether the quality of the communication link with a mobile station is bad. When the MAC logic in the base station ... WebThis work investigates HARQ buffer management by leveraging information-theoretic achievability arguments based on random coding. Specifical ly, standard HARQ schemes, namely Type-I, Chase Combining and Incremental Redundancy, are first studied under the assumpt ion of a finite-capacity HARQ buffer by considering both coded

WebThis paper analyses the performance of Chase Combining Hybrid Automatic Repeat Request (CC-HARQ) protocol in the novel 2024 IEEE 802.11 be physical layer (PHY) when it is implemented Low-Density Parity-Check (LDPC) codes over Doppler channels for the following transceiver architectures: downlink transmit beamforming (DL TxBF), DL multi … Although the HSDPA standard supports both Chase combining and incremental redundancy, it has been shown that incremental redundancy almost always performs better than Chase combining, at the cost of increased complexity. HARQ can be used in stop-and-wait mode or in selective repeat … See more Hybrid automatic repeat request (hybrid ARQ or HARQ) is a combination of high-rate forward error correction (FEC) and automatic repeat request (ARQ) error-control. In standard ARQ, redundant bits are added to data … See more HARQ is used in HSDPA and HSUPA which provide high speed data transmission (on downlink and uplink, respectively) for mobile phone networks such as UMTS, and in the IEEE 802.16-2005 standard for mobile broadband wireless access, also known as See more The simplest version of HARQ, Type I HARQ, adds both ED and FEC information to each message prior to transmission. When the coded data block is received, the receiver first … See more In practice, incorrectly received coded data blocks are often stored at the receiver rather than discarded, and when the re-transmitted block is received, the two blocks are combined. This is called Hybrid ARQ with soft combining (Dahlman et al., p. 120). While it is … See more • Soljanin, Emina; Ruoheng Liu; Predrag Spasojevic (2004).
