  • Publication number: 20210289580
    Abstract: Aspects presented herein may enable a UE to notify a base station about the availability of a relay UE that is not connected to the base station. In one aspect, a first UE or a second UE transmits or receives a relay request of the first UE via sidelink, the first UE being in an RRC connected mode with a base station. The first UE or the second UE receives or transmits, via the sidelink, an indication of relay availability of a second UE in an RRC inactive mode in response to the relay request. The first UE and the second UE receive a configuration from the base station for relay of communication from the base station over the sidelink between the first UE and the second UE.

  • Patent number: 11121739
    Abstract: In an aspect, a UE receives an SRS configuration that indicates, for at least one frequency hop, an allocation of less than all subcarriers of a sounding bandwidth to SRS per OFDM symbol in a respective frequency hop. The UE transmits, to a BS in a first frequency hop, OFDM symbols with SRS across all subcarriers of a first sounding bandwidth associated with the first frequency hop. In another aspect, the UE receives an SRS configuration that indicates, for frequency hops associated with the same comb-type, a sequence of resource element offsets that is based on a number of OFDM symbols used in the respective frequency hop. The UE transmits OFDM symbols with SRS in accordance with the sequence of resource element offsets indicated by the SRS configuration for the respective frequency hop.

  • Patent number: 11122512
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to be positioned in different possible physical configurations and may identify its current physical configuration based on a modem-based sensor. The UE may transmit a signal from a first antenna element and receive an echo of the signal at a second antenna element different than the first antenna element. The UE may then generate an echo signature for the echo of the signal and determine that the UE is in a first physical configuration (e.g., its current physical configuration) from the possible physical configurations by comparing the generated echo signature to a set of echo signatures that correspond to each of the possible physical configurations. Accordingly, based on the determined first physical configuration, the UE may perform an operating system function that corresponds to the first physical configuration.

  • Patent number: 11122614
    Abstract: Systems and methods of wireless communication in which wireless devices are adapted to implement adaptive waveform selection are disclosed. For example, operation according to embodiments may provide for use of a waveform design that minimizes peak-to-average power ratio (PAPR), such as single-carrier frequency division multiplexing (SC-FDM), as well as a waveform design that provides higher spectral efficiency, such as orthogonal frequency division multiplexing (OFDM), for scenarios that are not power-limited and the higher PAPR is acceptable. Adaptive waveform selection may be based implicitly on one or more parameters or may be based on explicit signaling. Adaptive waveform selection may be utilized with respect to initially establishing a communication link and/or with respect to an established communication link.

  • Publication number: 20210274543
    Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit a configured grant that indicates time-frequency resources for a user equipment (UE) to use to transmit sidelink or uplink messages in a wireless communications system. To reduce the amount of low priority traffic that may interfere with higher priority traffic, the base station may configure a threshold probability to allow high priority sidelink transmissions and to cancel low priority transmissions. The base station may transmit a cancellation indication that includes a priority indication instructing the UE to cancel transmissions having a priority less than a priority threshold during the allocated time-frequency resources. Based on transmitting the cancellation indication, the base station may cancel transmissions that have low priority, and the UE may determine whether to transmit (or to refrain from transmitting) one or more messages based on the priority of the message.

  • Publication number: 20210266772
    Abstract: Aspects described herein relate to determining and/or scheduling resources for devices in view of cross-channel interference measured between the devices. In an aspect, a first user equipment (UE) can determine a signal measurement of a signal transmitted by a second UE in a first channel, determine, based at least in part on the signal measurement, a cross-channel interference parameter of interference experienced by the first UE, and transmit, to a serving base station that serves the first UE, an indication of the cross-channel interference parameter. In another aspect, a base station can determine a cross-channel interference parameter of interference experienced by a first UE in at least a first channel, based on a signal transmitted by a second UE in a second channel, and can schedule communications for the first UE based at least in part on the cross-channel interference parameter.

  • Publication number: 20210266855
    Abstract: Certain aspects of the present disclosure relate to communication systems, and more particularly, to interpreting a timing advance (TA) command for members of a timing advance group (TAG), such as different uplink component carriers and/or different bandwidth parts, having different numerologies, such as different subarrier spacing (SCS). A method that may be performed by a user equipment (UE) includes receiving, from a base station (BS), a TA command. The UE interprets the TA command differently for different members of a same TAG, associated with different numerologies. The UE applies a timing adjustment when transmitting an uplink transmission to the BS based, at least in part, on the interpretation.

  • Publication number: 20210266917
    Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may be scheduled for communicating a first message over a first communication link with a base station and a second message over second communication link with a second UE. The first UE may select to communicate using the first communication link or the second communication link based on one or more prioritization rules that may involve the priority of the first message and the second message. The first UE may identify a mapping between the priority of the first message and the priority of the second message that may enable a comparison of the priorities of the first message and the second message. The first UE may select to communicate using the communication link of the message associated with the higher priority.

  • Publication number: 20210266928
    Abstract: Aspects relate to obtaining, at a first scheduled entity, a first priority ranking of first uplink (UL) data scheduled for transmission to a scheduling entity and a first data scheduled for transmission to a second scheduled data, as well as a second priority ranking of second data scheduled for transmission to a third and fourth scheduled entity, respectively. The scheduling uses at least a portion of a sidelink resource reserved for sidelink communication for the transmissions. The scheduling of the transmissions using at least the portion of the sidelink resource are based on the first priority ranking and the second priority ranking. Various transmission cancellation and reception preemptions are transmitted from transmitting scheduled entities to other transmitting or receiving scheduled entities, respectively. Such cancellations and preemptions are based on the priority rankings, prediction of data transmission collisions and prediction of interference at receiving entities.
