OFDM packing and LDPC framing for constellation shaping in NG WLANs
An apparatus for a station (STA) configured for operating in a next-generation (NG) wireless local area network (WLAN) comprises the processing circuitry configured to modify probabilities of constellation points to generate a more Gaussian distribution. In these embodiments, for LDPC framing and OFDM packing, the transmitter circuitry may be configured to compute a number of output bits (b.sub.out) to be transmitted based on a number of payload bits (b.sub.in) at an output of a shaping encoder, a shaping rate (r.sub.shaping), and an overhead percent (B.sub.overhead). A shaping gain of up to 1.53 dB may be achieved. A new shaping encoder is provided to address the issue that the number of bits is not fixed.
Method and an apparatus for determining a local frequency in wireless communication system
The disclosure relates to a communication scheme and system for converging a 5.sup.th generation (5G) communication system for supporting a data rate higher than that of a 4.sup.th generation (4G) system with an internet of things (IoT) technology. The disclosure is applicable to intelligent services (e.g., smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, and security and safety-related services) based on the 5G communication technology and the IoT-related technology. A method for determining a local frequency in a wireless communication system includes identifying frequency bands in use for communication, identifying, based on a first frequency band being in use for communication, a first subcarrier located at the center of the first frequency band among multiple subcarriers constituting the first frequency band, and determining a frequency between the first subcarrier and a second subcarrier closest to the first subcarrier as the local frequency.
Techniques for configuring search spaces for sidelink communication
Aspects of the present disclosure provide techniques for configuring a search space for sidelink communications between a plurality of user equipments (UEs). Particularly, the techniques described herein configure a search space (e.g., subset of all available sub-channels) to decode the sidelink packets (e.g., physical sidelink control channel (PSCCH) and physical sidelink shared channel (PSSCH)) transmitted between a first UE and a second UE over sidelink communication without the need for the receiver UE (e.g., second UE) to perform blind decoding of all sidelink sub-channels as is currently required in conventional systems. Thus, the disclosed techniques reduce latency and maximize the resource utilization (e.g., by using less processing power and bandwidth) for sidelink communications.
Method for efficient return channel spectrum utilization in a communication system supporting adaptive spread spectrum
An efficient return channel spectrum utilization technique for communication systems supporting adaptive spread spectrum. Requests for bandwidth allocation using a spread factor are analyzed to determine if there are any channels capable of supporting the spread factor. The request is acknowledged if at least one channel is capable of supporting the request. Adjacent channels required to accommodate the requested spread factor are reserved, and additional bandwidth requests are allocated on non-reserved channels.
HOP-COUNT INDICATION IN WIRELESS SYSTEMS
Methods, systems, and devices for wireless communications are described that provide for hop-count indication in an integrated access and backhaul (IAB) network. An IAB-node may adopt and indicate multiple values for hop-count. The hop-count may be conveyed by a number of different reference signals and channels. A resource pattern and/or a slot pattern may also be associated with the hop-count to simply signaling. By associating the patterns with the hop-count, an IAB-node may be able to infer the resource pattern used by another IAB-node.
Signaling Structure for Data Signaling
There is disclosed a method of operating a transmitting radio node (10, 100) in a wireless communication network, the method comprising transmitting data signaling in a signaling time interval, wherein an integer number CB of code blocks of data are associated to an integer number BS of allocation units of the signaling time interval.
The disclosure also pertains to related devices and methods.
