So in this paper, a new Hybrid Automatic Repeat reQuest (HARQ) mode, called Backoff HARQ, is proposed for contention-based (CB) transmission in 5G uplink. For Backoff HARQ mode, round trip time (RTT) is set to a longer random time. We can get more HARQ processes and put off the ...
Learn about physical uplink control channel (PUCCH) and uplink control information (UCI) in 5G New Radio. This video walks through the different types of messages, including HARQ, CQI, and scheduling requests. It discusses how they are encoded, modulated, and then mapped to the 5G New Rad...
It can receive HARQ feedback from AUX port for loop back test. Upon selecting this mode, the Waveform Setup node in the tree view changes to 5G NR Uplink and only the Basic property table is displayed with a subset of parameters. Additionally, instrument control buttons appear above the ...
enabled, Section 6.3.2.1.4 of TS 38.212 specifies the UCI bit sequence as the union of the CG-UCI bits and the HARQ-ACK bits. Therefore, the processing of UCI on PUSCH considers any active CG-UCI source as an extension to HARQ-ACK and only the value ofBetaOffsetACKis used in this ...

Multiple types of control and signaling information are carried via uplink control channels in order to support various air interface procedures. The uplink control information is categorized into the following: • Primary Fast-Feedback Channel; • Secondary Fast-Feedback Channel; • HARQ Feedba...
Uplink Control for Low Latency HARQ in TDD Carrier Aggregation A higher data rate and lower latency are two main features of Long Term Evolution Advanced (LTE-A). In order to support a higher peak data rate, carrier ag... Y Lu,L Liu,M Li,... - Vehicular Technology Conference 被引量...
propose the cross layer resource allocation algorithm considering channel state information in layer 1 and rate-distortion function in layer 5, for uplink convolutional coded OFDMA video transmission systems. In this paper, we propose the use of hybrid automatic repeat request protocol (HARQ) and ...
A base station receives an uplink data packet from a user equipment based on a synchronous hybrid automatic repeat request (HARQ) protocol, and transmits a first information element and a second information element in parallel to the use... Joachim LOHR,E Seidel,D Petermann - US 被引量: 4...
