    摘要: Methods, systems, and devices for wireless communication are described. A communication device, such as a user equipment (UE) may determine a transmit diversity configuration indicating a transmit diversity criterion for declaring a result of a channel access procedure for a plurality of component carriers in a shared radio frequency spectrum band. The UE may perform the channel access procedure for the plurality of component carriers in the shared radio frequency spectrum band to determine the result of the channel access procedure based at least in part on the transmit diversity criterion. As a result, the UE may transmit or refrain from transmitting a message over at least one component carrier of the plurality of component carriers based at least in part on the result of the channel access procedure.

    摘要: Aspects of the disclosure relate to a wireless user equipment (UE) determining a wideband channel quality indicator (CQI) in a wireless communication network. For each of a plurality of CQI hypotheses, a UE divides a bandwidth into a plurality of frequency segments and determines an average spectral efficiency (SPEF) for each of those segments. Further, for each of the plurality of CQI hypotheses, the UE determines the minimum of the average SPEFs. The UE selects the CQI hypothesis corresponding to the maximum from among these determined minimum average SPEFs, and transmits this selected CQI as a wideband CQI. Other aspects, embodiments, and features are also claimed and described.

    摘要: Methods, systems, and devices for wireless communications are described for shared radio frequency spectrum band access information. A sensing device may monitor one or more frequencies of the shared radio frequency spectrum band and may receive signaling indicating access information (e.g., automated frequency control information). The access information may indicate one or more frequencies of the shared radio frequency spectrum band that are accessible for the sensing device. The scheduling device may obtain the access information from an access point, local storage media, or the like. In some examples, the scheduling device may transmit signaling indicating the accessible frequencies based on a request message from the sensing device. The sensing device may receive the access information and may communicate on one or more of the indicated frequencies accordingly.

    摘要: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, for a first radio access technology, signaling identifying a set of physical resource blocks for a tracking reference signal transmission configured in a bandwidth part of a system bandwidth. The UE may determine that a collision condition is satisfied for a first one or more physical resource blocks of the set of physical resource blocks. The UE may receive the tracking reference signal transmission in a second one or more physical resource blocks of the set of physical resource blocks based at least in part on determining that the collision condition is satisfied for the first one or more physical resource blocks. Numerous other aspects are provided.

    摘要: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a transmit diversity configuration for transmitting multiple sidelink messages. The UE may identify a transmit diversity configuration that indicates a set of component carriers (CCs) available for sidelink communication. The UE may transmit, based on the transmit diversity configuration, a first sidelink message having a first redundancy version (RV) of a transport block (TB), and a second sidelink message having a second RV of the TB, on multiple CCs. In a second case, the UE may identify a transmit diversity configuration indicating a set of precoding matrices. The UE may transmit the first sidelink message, including a TB or an RV of a TB, precoded using a first precoding matrix and a second sidelink message, including a TB or an RV of a TB, precoded using a second precoding matrix on multiple CCs.
