An transmission apparatus of the present disclosure comprises a transmission signal generator which, in operation, generates a transmission signal that includes a legacy preamble, a non-legacy preamble and a data field, wherein the non-legacy preamble comprises a first signal field and a second signal field, the second signal field comprising a first channel field and a second channel field, each of the first channel field and the second channel field comprising a common field that carries resource unit (RU) allocation information and a user-specific field that carries per-user allocation information for one or more terminal stations, and wherein a part of the user-specific field of one of the first channel field and the second channel field whichever is longer than the other channel field in length before appending padding bits is relocated to the other channel field; and a transmitter which, in operation, transmits the generated transmission signal.

A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may schedule a mini-slot for transmission of unicast data to a particular user equipment. The mini-slot may be scheduled in a portion of a downlink common burst portion of a slot. The apparatus may transmit a signal, including the unicast data, within the mini-slot.

A configuration to configure a UE to utilize a layer mapping configuration for mapping coded data. The apparatus applies a layer mapping order for mapping coded data in time, frequency, and a plurality of spatial layers for a plurality of UEs configured in cooperation or a plurality of panels configured in cooperation. The apparatus exchanges the coded data with a base station based on the layer mapping order.

An access point (AP), a station (STA), and an information transmission method are provided. The information transmission method includes configuring, by an access point (AP), an aggregated physical layer (PHY) protocol data unit (A-PPDU) used for downlink transmission to a set of STAs, wherein the A-PPDU comprises a first PPDU and at least one second PPDU if a number of first symbols of the first PPDU is equal to a number of second symbols of the second PPDU and/or a first field of the first PPDU has a same symbol duration and/or a same guard interval (GI) duration as a second field of the second PPDU; and determining, by the AP, an uplink transmission from a STA of the set of STAs, wherein the uplink transmission is in response to the A-PPDU used for downlink transmission. This can aggregate different formats of PPDUs.

An method includes determining to perform inter-cell multi-downlink control information (multi-DCI) based multi-transmission reception point (multi-TRP) operation for a user device based on the following: receiving, by the user device from a network node, transmission configuration index (TCI) states for a plurality of control resource sets (CORESETS), wherein the TCI states for the plurality of CORESETs are associated with a plurality of cells having different physical cell identities (PCIs) or associated with a plurality of cell groups; and determining, by the user device, that at least one of the following conditions is present: 1) a multi-DCI based multi-TRP-related high layer parameter has been configured to the user device; 2) a default mode of multi-TRP operation has been configured to the user device; or 3) the user device has received control information indicating physical downlink shared channel (PDSCH) TCI state activations corresponding to two different CORESETPoolIndex values; and, performing inter-cell multi-DCI based multi-TRP operation.

The apparatus may be configured to configure a downlink BWP and an uplink BWP having at least one of a restricted uplink portion, a restricted downlink portion, or a guard band associated with one or more of the downlink BWP or the uplink BWP. The apparatus may also be configured to communicate with one or more UEs in the restricted downlink portion of the downlink BWP and the restricted uplink portion of the uplink BWP. The apparatus may be configured to transmit, to a first UE in a half-duplex mode of operation, an indication of a first set of resources for a full-duplex mode of operation of the base station and a second set of resources for the half-duplex mode of operation of the base station. The apparatus may also be configured to communicate with the first UE in the indicated first set of resources.

Uplink access in 5G and 6G is tightly controlled by the base station. Prior art procedures can impose access delays, such as waiting for a periodic scheduling request opportunity, which may be excessive for some user devices. Disclosed is a compact and responsive procedure for the base station to provide access to high-priority user devices first, and then low-priority user devices in a cascaded manner. The low-priority user devices are allocated to sections and, on a periodic schedule, can transmit a signal indicating which sections include at least one user device seeking access. Then the base station can provide a user poll region in which the ready user devices can submit their scheduling requests on pre-assigned subcarriers, but including only those sections that have at least one ready user devices. High-priority users are thus served first, while time and resources are saved by ignoring sections that have no ready users.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first configuration communication associated with a first shared channel communication that includes a first demodulation reference signal (DMRS) having a first configurable DMRS lifespan, wherein the first configuration communication comprises a DMRS sharing indication associated with reuse of the first DMRS associated with a second shared channel communication. The UE may receive the first shared channel communication. The UE may receive the second shared channel communication based at least in part on the DMRS sharing indication. Numerous other aspects are described.

According to one embodiment, a wireless device includes a transmitter; and a receiver. The transmitter is configured to transmit a first frame including information that designates a plurality of frequency components and instructing execution of frequency multiplexing transmission by a plurality of wireless communication terminals; and the receiver is configured to receive the second frame by at least one frequency component of the plurality of frequency components. The first frame has either a first form or a second form, the first form designates individual terminal identifiers of the plurality of wireless communication terminals, the terminal identifiers each being associated with at least one of the plurality of frequency components, and the second form designates a group identifier of a group to which the plurality of wireless communication terminals belong.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a sidelink cancellation indication that indicates a set of resources in which to cancel sidelink communications, wherein the set of resources overlaps with at least one of a physical sidelink feedback channel (PSFCH), a gap symbol, or a sidelink synchronization signal block (S-SSB). The UE may perform one or more sidelink cancellation actions associated with the at least one of the PSFCH, the gap symbol, or the S-SSB. Numerous other aspects are described.
