  • Publication number: 20230036652
    Abstract: Methods, systems, and devices for wireless communications are described in which multiple operators may perform spectrum sharing using shared radio units (RUs), where the multiple different operators can access a same RU for communications with a user equipment (UE). A shared RU may receive requests for resources from two or more network nodes of two or more different network operators, for wireless resources in a first time period. The RU may determine a first resource allocation for the first time period based on different priorities of the different network operators. A first network operator may have a higher priority than a second or third network operator, and resources may be allocated to the first network operator ahead of the second or third network operators. The RU may transmit the first resource allocation to each of the different network nodes that transmitted requests for resources.

  • Publication number: 20230034433
    Abstract: Disclosed are techniques for wireless communication. In an aspect, a position estimation entity (e.g., UE, gNB, LMF, etc.) identifies a pool of UEs for a SL-assisted position estimation procedure of a set of target UEs. SL SRS-Ps are communicated (e.g., transmitted and measured) between the pool of UEs (e.g., for relative SL ranging). UL SRS-Ps are communicated by at least some of the UEs in the pool of UEs. The position estimation entity obtains measurement data for both the SL SRS-P and UL-SRS-P communications. The position estimation entity determines a position estimate for each UE in the set of UEs based on the measurement information.

  • Patent number: 11570806
    Abstract: Certain aspects of the present disclosure provide techniques for sending a configuration for conditional configured grant (CG) occasions for uplink transmission to a user equipment (UE). Each conditional CG occasion may be associated with multiple conditional CG resources. Each conditional CG resource may be associated with a sending window. The UE may monitor within sensing windows for conditional CG resources of a certain conditional CG occasion for over the air (OTA) signals from other UEs to determine if the conditional CG resources are available for uplink transmission. The UE may skip the conditional CG occasion when the conditional CG resources are not available. The UE may perform uplink transmission on the conditional CG resources when the conditional CG resources are available.

  • Publication number: 20230026028
    Abstract: This disclosure provides systems, methods, and devices for wireless communication that support managing allocation of configured grant (CG) resources for uplink transmissions using a polynomial over Galois field in a wireless communication system. In particular, a user equipment (UE) may be configured (e.g., by a base station) to determine a resource to access, from a resource pool configured for each CG occasion of a CG configuration, based on a polynomial over Galois field configured for the UE. The polynomial over Galois field may include a parameter p, and the UE may be configured with a mapping that maps the absolute time (e.g., a slot index or a symbol index) of a GC occasion to an index between 0 and p?1 that is used as input to the polynomial The result of the polynomial is used to determine the resource to access by the UE at the CG occasion.

  • Patent number: 11558902
    Abstract: Aspects relate to spectrum sharing for use in a wireless communication network that serves both prioritized and non-prioritized user access terminals. In one example, a user access terminal, e.g., a user equipment (UE), senses an amount of signal energy within a frequency band during one or more sensing intervals in response to a determination that the access terminal is a non-prioritized access terminal. If the amount of signal energy does not exceed a sensed energy threshold, the user access terminal transmits wireless signals following the sensing intervals. On the other hand, if the amount of signal energy exceeds the sensed energy threshold, the user access terminal modifies transmissions while the amount of signal energy sensed during one or more subsequent sensing intervals exceeds the sensed energy threshold. For example, the access terminal may delay or adjust transmissions until the amount of signal energy no longer exceeds the sensed energy threshold.

  • Publication number: 20230008727
    Abstract: Methods, systems, and devices for wireless communications are described. A first device may cooperate with a second device to form a virtual device configured to communicate with a radio access network. The virtual device may appear as a single device from the perspective of the radio access network. Subsequently, a third device may be identified for replacing the second device within the virtual device. Based on the third device being identified, procedures for handing over communications from the second device to the third device may be executed. The procedures may include a beam management procedure, a random-access procedure, a mobility management procedure, or any combination thereof.

  • Publication number: 20230011514
    Abstract: Aspects relate to techniques for enhancing sidelink scheduling information to include a priority assigned to a sidelink transmission. For example, a transmitting wireless communication device may receive sidelink scheduling information scheduling a sidelink transmission from a transmitting wireless communication device to a receiving wireless communication device. The sidelink scheduling information may further include a priority indicator associated with the sidelink transmission. The transmitting wireless communication device may then transmit the sidelink transmission to the receiving wireless communication device based on the scheduling information. The priority indicator may further facilitate hybrid automatic repeat request (HARQ) codebook construction on the sidelink and uplink for the transmission of acknowledgement information of the sidelink transmission.
