Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may monitor a subset of time resources in a wake up signal (WUS) pool, wherein the WUS pool includes contiguous candidate time resources for receiving a WUS. The UE may detect the WUS based at least in part on monitoring the subset of time resources. Numerous other aspects are provided.

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 tone mapping techniques and packet designs that support duplicate (or “DUP mode”) transmissions to multiple users. In some implementations, an access point (AP) may transmit a PPDU that includes first user data and second user data, where at least the first user data is transmitted in a DUP mode. As such, the first user data may be mapped to a number (N) of tones spanning a first RU in accordance with a dual carrier modulation (DCM) scheme, and a duplicate copy of the first user data may be mapped to N tones spanning a second RU in accordance with the DCM scheme. In some implementations, the second user data also may be transmitted in a DUP mode.

Polling to determine which user devices wish to transmit, is a time-consuming and resource-intensive process in 5G and 6G. Procedures disclosed herein can provide a fast, extremely compact sequence whereby the base station can determine which users are ready to transmit. First, the base station divides the users into a number of sections, and assigns each user a position in its section. Then, in a “section poll”, the user devices indicate which sections include at least one ready user, and the base station broadcasts a terse listing of these section numbers. Then, in a subsequent “user poll”, the ready users specifically identify themselves, with another compact format. For example, the section poll may use just a single resource element per section, and the user poll may include only those sections that have at least one ready user. These resource-efficient protocols can thereby save energy and time while minimizing background generation.

The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). Disclosed is a method of defining a resource block or resource element offset for mapping PTRS to a symbol, wherein the offset is determined based on an identifier of a particular user equipment, UE.

Provided is a wireless communication terminal that communicates wirelessly. The terminal includes: a transceiver; and a processor. The terminal includes a transceiver, and a processor. The processor is configured to receive an Aggregate-MAC Protocol Data Unit (A-MPDU) from an originator using the transceiver, and when receiving all MPDUs included in the A-MPDU, transmit to the originator a block ACK (BA) frame signaling that all MPDUs included in the A-MPDU are received without a bitmap indicating whether each MPDU included in the A-MPDU is received.

The present disclosure relates to a skywave large-scale MIMO communication method, model, and system. A skywave communication base station in a short waveband is constructed using a large-scale antenna array, wherein skywave large-scale MIMO communication is carried out between the skywave communication base station and a user terminal in a coverage area by ionospheric reflection. The skywave communication base station determines a spacing of the large-scale antenna array according to a maximum operating frequency, and communicates with the user terminal based on a TDD communication mode, wherein a skywave large-scale MIMO signal is transmitted based on an OFDM modulation mode or a power efficiency improvement modulation mode. The skywave communication base station selects a communication carrier frequency within a short waveband range according to a real-time ionospheric channel characteristic, and adaptively selects an OFDM modulation parameter and a signal frame structure.

One or more techniques for sharing control channel and pilot resources are disclosed.

A method of operating a first apparatus 100 in a wireless communication system is proposed. The method may comprise: performing partial sensing on at least one sidelink (SL) slot related to at least one first candidate slot to be subject to resource re-evaluation or pre-emption; performing the resource re-evaluation or the pre-emption based on a result of the partial sensing; and performing resource selection based on the resource re-evaluation or the pre-emption.

Methods, systems, and devices are described for hierarchical communications and low latency support within a wireless communications system. An eNB and/or a UE may be configured to operate within the wireless communications system which is at least partially defined through a first layer with first layer transmissions having a first subframe type and a second layer with second layer transmissions having a second subframe type. The first subframe type may have a first round trip time (RTT) between transmission and acknowledgment of receipt of the transmission, and the second layer may have a second RTT that is less than the first RTT. Subframes of the first subframe type may be multiplexed with subframes of the second subframe type, such as through time division multiplexing. In some examples symbols of different duration may be multiplexed such that they different symbol durations coexist.

The present disclosure relates to a resource allocation procedure for allocating time-frequency radio resources by a scheduler in a mobile communication system. A plurality of numerology schemes are defined, each partitioning a plurality of radio resources of the mobile communication system into resource scheduling units in a different manner. A reference resource set is defined per numerology scheme, each being associated to a set of radio resources usable for being allocated according to the respective numerology scheme. The reference resource set of at least one numerology scheme overlaps with the reference resource set of at least another numerology scheme in the frequency and/or time domain. The resource allocation procedure is performed for allocating radio resources to one or more user terminals according to the numerology schemes. The resource allocation procedure is performed for each numerology scheme based on a scheduling time interval defined for the respective numerology scheme.
