Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a resource allocation indicating a set of transmission tones comprising a set of data tones and a set of peak reduction tones (PRTs), wherein the resource allocation indicates locations for the set of data tones and locations for the set of PRTs within a particular bandwidth, wherein the locations for the set of PRTs are arranged relative to the locations for the set of data tones according to a PRT sequence, and wherein the PRT sequence comprises a plurality of contiguous PRTs arranged relative to a plurality of contiguous data tones or a pseudo-random pattern generated using a pseudo-random number generator; and transmit a data transmission using a waveform based at least in part on the resource allocation. Numerous other aspects are provided.
Abstract:
This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for interference measurement and reporting by a UE. The interference measurement can be self-initiated by the UE or based on a request received from a BS. To measure the interference, the UE transmits a first signal in UL resources to a first BS concurrently with receiving a second signal in DL resources from one of the first BS or a second BS. The received second signal includes interference associated with the transmitted first signal. Based on the received second signal, the UE determines a level of the interference that is associated with the transmitted first signal. Information associated with the level of the interference is then transmitted to the first BS, such as an indication of a guard band that is to be incorporated between the UL resources and the DL resources.
Abstract:
A base station is disclosed that includes two separated antenna arrays. In a TDD mode of operation, both arrays are used for either transmit or receive. In a sub-band full-duplex mode of operation, one array is used to transmit downlink symbols while the remaining array is used to receive uplink symbols.
Abstract:
Methods, systems, and devices for wireless communication are described. A wireless device may identify an uplink/downlink (UL/DL) configuration that defines subframe configuration options for each subframe of a frame. For example, the UL/DL configuration may establish parameters for time division duplexing (TDD) operation between a base station and a user equipment (UE). The wireless device (e.g., the UE or base station) may determine a constraint for a subframe of the frame based on the UL/DL configuration and then determine an adaptive subframe configuration based on the constraint. The adaptive subframe configuration may include one or several downlink symbol periods and one or several uplink symbol periods. The wireless device may then communicate during the subframe according to the adaptive subframe configuration rather than the original UL/DL configuration; and, because the adaptive subframe may be constrained by the identified UL/DL configuration, the communication during the subframe may avoid disruption to UEs.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiving device may determine an uplink-downlink time division duplex (TDD) shortened transmission time interval (sTTI) configuration; determine an initial sTTI, within the uplink-downlink TDD sTTI configuration, for reception of an initial communication; and monitor one or more sTTIs, subsequent to the initial sTTI, for reception of at least one repetition or retransmission of the initial communication, wherein the one or more sTTIs are determined based at least in part on a pattern associated with the uplink-downlink TDD sTTI configuration. Numerous other aspects are provided.
Abstract:
Aspects of the present disclosure describe communicating control data based on reference signals in wireless communications. A timeline for transmitting uplink communications can be determined, where the timeline can relate to whether to process downlink communications based on at least one of a first type of reference signal (RS) or a second type of RS, a length or number of symbols in the reference signal, or a timing advance.
Abstract:
Certain aspects of the present disclosure provide techniques that may be used to help enable low latency communications between a user equipment (UE) and a base station (BS) using quick uplink channels that enable a reduced transmission time interval (TTI). An example method generally includes identifying a plurality of slots in a subframe, receiving a resource configuration for an uplink channel, wherein the resource configuration is associated with a first slot of the plurality of slots, determining a resource for transmitting the uplink channel in a second slot of the plurality of slots, wherein the resource is determined based on the resource configuration associated with the first slot of the plurality of slots, and transmitting the uplink channel in the second slot using the determined resource.
Abstract:
Certain aspects of the present disclosure provide methods for wireless communications by a base station and a user equipment in a network. An exemplary method generally includes performing a discovery procedure to identify one or more devices through which the UE may indirectly communicate with a base station in the network and deciding based on one or more criteria whether to communicate with the base station directly or to communicate with the base station indirectly via a device identified by the discovery procedure. According to certain aspects, when a UE is in communication with a network indirectly, the network might page the UE directly, indirectly, or both.
Abstract:
Various aspects described herein relate to wireless communications, including generating a waveform including a combined reference signal and control data signal, the reference signal and the control data signal being phase offset from one another in the waveform, and transmitting the waveform on one resource block in a transmission time interval having a duration that is less than a subframe.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network node, capability information indicating one or more sub-band full-duplex (SBFD) support conditions for the UE. The UE may communicate with the network node based at least in part on the one or more SBFD support conditions for the UE. Numerous other aspects are described.
