METHOD AND APPARATUS FOR RANDOM ACCESS PROCEDURE
Methods and apparatuses for random access procedure. A method at a terminal device comprises receiving information of a physical uplink shared channel (PUSCH) resource allocation mode from a network node. The PUSCH resource allocation mode includes at least one of interlace or non-interlace. The method further comprises transmitting a first message including a random access preamble and payload to the network node. The payload is transmitted on a PUSCH based on the PUSCH resource allocation mode.
SIGNALING FOR DATA DUPLICATION TRANSMISSION
In a wireless local area network (WLAN) system, a transmission station (STA) may transmit a PPDU including a first data field and a second data field to a reception STA, and the second data field may be generated by duplicating the first data field. The PPDU may include information indicating that the first data and the second data are the same data.
FORWARD-COMPATIBLE PUNCTURING INDICATIONS
This disclosure provides systems, methods, and apparatuses for wireless communication that can be used for channel puncturing. A wireless station (STA) may receive an indication of a first puncturing pattern to be used for transmitting or receiving data over a wireless channel, where the first puncturing pattern is defined by a first wireless communication protocol release and the STA is configured to operate according to a second wireless communication protocol release. The STA may select, from a set of puncturing patterns defined by the second wireless communication protocol release, a second puncturing pattern that includes one or more non-punctured subchannels that are subsets of one or more corresponding non-punctured subchannels of the first puncturing pattern. The STA may use the second puncturing pattern to transmit or receive one or more packets over the wireless channel.
DISTRIBUTED RESOURCE UNIT TRANSMISSION
This disclosure provides methods, devices and systems for increasing the transmit power of wireless communication devices operating on power spectral density (PSD)-limited wireless channels. Some implementations more specifically relate to physical layer (PHY) convergence protocol (PLCP) protocol data unit (PPDU) designs that support distributed transmission. In some implementations, a PPDU may be generated based on one or more legacy tone plans. In such implementations, a portion of the PPDU may be modulated on a number (M) of tones representing a logical RU, and the M tones may be further mapped to M noncontiguous subcarrier indices in accordance with a distributed tone plan. In some other implementations, a PPDU may be generated based on a distributed tone plan. In such implementations, a portion of the PPDU may be modulated on a number (M) of tones coinciding with M noncontiguous subcarrier indices in accordance with the distributed tone plan.
Enhancements on random access for NR-unlicensed
A network device (e.g., a user equipment (UE), or a new radio NB (gNB)) can process or generate a configuration of a physical random access channel (PRACH) over physical resource blocks (PRBs) that are interlaced in an unlicensed band in an NR unlicensed (NR-U) communication. The PRBs in the PRACH can be based on an occupied channel bandwidth (OCB) of the unlicensed band in the NR-U communication. A random access channel transmission in the PRACH can then be generated by interlacing the PRBs defining the PRACH.
Methods of efficient wideband operation for intra-band non-contiguous spectrum
A method of efficient wideband operation for intra-band non-contiguous spectrum using extending bandwidth part (BWP) configuration is proposed. The BWP definition is extended to cluster BWPs to aggregate distributed spectrum blocks within a frequency range (e.g., 200 MHz) by single carrier operation and facilitate UE to filter out the transmission of unknown RAT between any two of the distributed spectrum blocks. In addition, the cluster BWP configuration enables dynamic aggregation of the number and location of the distributed spectrum blocks based on LBT results in unlicensed spectrum. Specifically, the BWP definition is extended to a group of one or multiple radio resource clusters, each of which contains a set of contiguous PRBs in frequency domain within the associated carrier.
APPARATUS AND METHODS FOR ENHANCING QUALITY OF EXPERIENCE FOR DATA SERVICES OVER HIGH-CAPACITY WIRELESS NETWORKS
Apparatus and methods for guaranteeing a quality of experience (QoE) associated with data provision services in an enhanced data delivery network. In one embodiment, a network architecture having service delivery over at least portions of extant infrastructure (e.g., a hybrid fiber coax infrastructure) is disclosed, which includes standards-compliant ultra-low latency and high data rate services (e.g., 5G NR services) via a common service provider. In one exemplary implementation, “over-the-top” voice data services may enable exchange of voice traffic with client devices in the aforementioned network. A distribution node may use a detection rule to identify received packets as voice traffic, and cause a dedicated bearer to attach to the default bearer, thereby enabling delivery of high-quality voice traffic by at least prioritizing the identified packets thereafter and sustaining the delivery even in a congested network environment, and improving the quality of service (QoS) and QoE for the user(s).
Communication apparatus and method for discrete fourier transforming a time signal to a frequency signal
A communication system includes a communication apparatus and a base station. The communication apparatus includes a Discrete Fourier Transform (DFT) transformer which transforms a time-domain signal into a frequency-domain signal with a DFT size that is a product of powers of a plurality of values; a mapper which maps the frequency-domain signal on a plurality of frequency bands, each frequency band being located at a position separate from position(s) of other(s) of the plurality of frequency bands; and a signal generator which generates a single carrier-frequency division multiple access (SC-FDMA) time-domain signal from the mapped signal. The base station includes a receiver which receives the SC-FDMA time-domain signal; a combiner which generates the frequency-domain signal from the SC-FDMA time-domain signal; and a transformer which transforms the frequency-domain signal into the time-domain signal with an inverse Discrete Fourier Transform (IDFT) having the DFT size.
CONTROL SIGNALING IN LTE CARRIER AGGREGATION
Methods and devices may be provided for aggregating component carriers in the licensed spectrum with at least one component carriers in the licensed exempt spectrum. Control information may be processed in a wireless transmit/receive unit (WTRU) while receiving and sending information on a primary component carrier (PCC) and a supplementary component carrier (SuppCC). A PCC subframe with a control portion and a data portion may be received. Resource assignment information associated with a downlink shared channel on the PCC may be embedded in the control portion of the subframe. Based on the resource assignment information on the PCC, resource assignment information associated with a downlink shared channel on the SuppCC may be identified in the data portion of the PCC subframe. A SuppCC subframe of the shared channel on the SuppCC may be processed as per the identified resource assignment information associated with the downlink shared channel on the SuppCC.
DISTRIBUTED RESOURCE UNIT SIGNALING
This disclosure provides methods, devices and systems for increasing the transmit power of wireless communication devices operating on power spectral density (PSD)-limited wireless channels. Some implementations more specifically relate to signaling in a trigger frame to support distributed transmissions via distributed resource units (dRUs). In some implementations, an access point (AP) may transmit a trigger frame soliciting a trigger-based (TB) physical layer convergence protocol (PLCP) protocol data unit (PPDU) from a wireless station (STA), where the trigger frame carries RU allocation information identifying a distributed resource unit (dRU) allocated for the STA and carries tone mapping information indicating a selected spreading bandwidth design for the wireless channel or subchannel. The AP can support channel puncturing by selecting a particular spreading bandwidth design that controls how dRUs are mapped to non-contiguous tones spanning respective spreading bandwidths.
