    Abstract: Methods, systems, and devices for wireless communications are described. A base station of a first network operator (OP) may determine a priority for the first OP for a transmission opportunity of a shared or unlicensed channel. The priority may be lower than a priority of a second OP for the transmission opportunity. Base station may transmit a tentative grant to a user equipment (UE) of the first OP scheduling transmissions over resources of the transmission opportunity. The transmitting device of the first OP may monitor a contention window for reservation signals communicated by devices of the second OP. Based on the monitoring and the tentative grant, the transmitting device of the first OP may perform the transmission over the resources of the shared or unlicensed channel.

    Abstract: The present disclosure provides for fast radio resource management procedures for new radio. Generally, a fixed frame structure is utilized and all base stations are synchronized. A base station may transmit a reservation request during a first control slot for the base station in a reservation channel at a beginning of a synchronized frame. A first user equipment may transmit and the base station may receive a reservation response during a second control slot. The base station may receive, from the first UE, after a third control slot of the reservation channel for a neighboring base station, a reservation indication based on a measurement by the first UE of the neighboring base station or at least one other UE associated with the neighboring base station. The base station may determine, based on the resource indication, whether to schedule the first UE during a data channel of the synchronized frame.

    Abstract: A method and apparatus for demapping a double squared quadrature amplitude modulated (DSQ) symbol is disclosed. One or more first log likelihood ratios (LLRs) are determined, for a first subset of constellation points of a corresponding DSQ constellation, using an LLR approximation. One or more second LLRs are determined, for a second subset of constellation points of the DSQ constellation, using a lookup table. The DSQ symbol is then demapped to one of a plurality of constellation points of the DSQ constellation based on the first and second LLRs. For some embodiments, the first subset of constellation points may correspond with an inner region of the DSQ constellation and the second subset of constellation points may correspond with an outer region of the DSQ constellation.

    Abstract: A receiver is disclosed that includes a slicer having an input to receive a sequence of symbols exhibiting inter-symbol-interference (ISI). The slicer determines a state associated with each symbol based on a threshold. A feedback equalization unit is coupled to the slicer to apply equalization to the symbol fed to the slicer input based on prior detected symbol states. A Least-Mean-Square (LMS) unit cooperates with the slicer and feedback equalization unit to estimate a channel impulse response based on the equalized symbols. The LMS unit feeds the estimated channel impulse response to a Maximum-Likelihood-Sequence-Estimation (MLSE) unit to generate an estimated sequence of bits based on the estimated channel impulse response.

    Abstract: Aspects relate to techniques for exchanging resource pool (RP) configurations between wireless communication devices. A transmitting wireless communication device can transmit a remaining minimum system information (RMSI) message including a RP configuration of the transmitting wireless communication device to at least one receiving wireless communication device. The RMSI message is transmitted within a minimum resource block set that is common to both the transmitting wireless communication device and the at least one receiving wireless communication device. The transmitting wireless communication device may then communicate with the at least one receiving wireless communication device on a sidelink based on the RP configuration.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a helper user equipment (UE) may receive, from a base station, a signaling message requesting the helper UE to monitor for and transmit a sidelink communication in a manner that uses a single-frequency network, wherein the sidelink communication is to be transmitted by a source UE to a destination UE that is different from the helper UE. The helper UE may receive the sidelink communication, transmitted by the source UE to the destination UE, in a first time-frequency resource of the single-frequency network. The helper UE may transmit the sidelink communication in a second time-frequency resource of the single-frequency network, wherein the second time-frequency resource is indicated to the helper UE by the base station. Numerous other aspects are described.
