Embodiments of the present disclosure provide methods and apparatus for antenna calibration. A method implemented at a network function comprises calibrating an antenna of the network function based on available time-frequency resources. The method further comprises communicating with at least one terminal device via the calibrated antenna.

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may determine to use multi-cluster communications in a vehicle based communication network. The UE may identify a configuration parameter associated with the multi-cluster communications. The UE may select a cluster resource from a set of available cluster resources based on the configuration parameter. The cluster resource may include one or more clusters used for multi-cluster transmissions in the vehicle based communication network. The UE may transmit an indication of the selected cluster resource to a wireless node of the vehicle based communication network, for example, to another UE. The UE may transmit the multi-cluster transmission on the selected cluster resource.

An aspect of this disclosure relates to a relay node, and a method of wireless communications by the relay node, including attempting to decode first code block groups of a transport block received in a resource allocation and according to a first encoding configuration. The aspects include identifying a symbol in the resource allocation that includes both of a first part of a successfully decoded one, and a first part of an unsuccessfully decoded one, of the plurality of first code block groups, and determining a modified transmit configuration for the symbol. Further, the aspects include encoding a second part of the successfully decoded one according to the first encoding configuration to define a second code block group that is outside of the symbol. Additionally, the aspects include transmitting the transport block including the one or more second code block groups and the symbol according to the modified transmit configuration.

A data transmission method includes sending, by a master station (STA), a request to send (RTX) to an access point (AP) in a same basic service set (BSS), which includes the AP and multiple STAs, and the master STA is a STA that is the first to obtain a channel by contention in the multiple STAs, instructing a surrounding STA to determine, according to conditions, whether to follow the master STA to send an RTX, where a STA following the master STA to send the RTX satisfies conditions that the STA has buffer data to be transmitted, the STA is in the same BSS as the master STA, and a power of a signal received from the master STA is greater than a preset threshold, and receiving response information from the AP to transmit uplink data on a specified sub-channel.

Methods, systems, and devices for wireless communication are described. A first cell may receive a message indicating that a second cell has a priority transmission scheduled using a transmit time interval (TTI) that is shorter than a TTI used by the first cell. The first cell may limit, based on the message, a communication parameter associated with communications between the first cell and a user equipment (UE) during the scheduled priority transmission.

An integrated circuit includes control circuitry and transmitting circuitry. The control circuitry maps data or a reference signal onto resources including orthogonal subcarriers of a first numerology and a second numerology, which differ at least by subcarrier spacing and are frequency-multiplexed on a subcarrier basis. The control circuitry assigns no transmit power to at least one subcarrier located between a subcarrier of the first numerology and a subcarrier of the second numerology. The subcarriers of the second numerology include: inter-numerology-orthogonal subcarriers, each of which is centrally aligned with a subcarrier of the first numerology, and non-inter-numerology-orthogonal subcarriers not centrally aligned with any subcarrier of the first numerology and located between two adjacent subcarriers of the first numerology. The control circuitry assigns no transmit power to at least one of the non-inter-numerology-orthogonal subcarriers. The transmitting circuitry transmits the mapped data or reference signal.

A method for operating a transmission-reception point (TRP) includes determining a first cycle of backhaul communications modes for the TRP, each backhaul communications mode of the first cycle is associated with a different time period and prompts the TRP to either transmit or receive using a subset of communications beams available to the TRP during an associated time period, wherein the communications beams used by the TRP and neighboring TRPs of the TRP in each associated time period are selected to prevent mutual interference, and wherein at least one backhaul communications mode of the first cycle prompts the TRP to either transmit or receive using all of the communications beams available to the TRP, determining a backhaul frame configuration for the TRP in accordance with the first cycle, the backhaul frame configuration specifying an arrangement of subframes of a frame used for backhaul communications.

A receiver is configured to detect a plurality of signals on a plurality of subbands over a communication channel that operates on a shared or an unlicensed spectrum. Additionally, the receiver is configured to perform joint correlation over a time domain and a frequency domain of each successive signal of the plurality of signals. Moreover, the receiver is configured to determine a sequence based on the joint correlation. Additionally, the receiver is configured to decode transmission information from the sequence.

An electronic apparatus includes transmitter circuitry configured to transmit a first association request frame to a first electronic apparatus; and receiver circuitry configured to receive a first association response frame corresponding to the first association request frame from the first electronic apparatus, and to receive a second association request frame from the first electronic apparatus.

Various aspects of the disclosure relate to beam information for independent links. For example, beam information for one link may be sent on at least one other link. In some aspects, the independent links may involve a first device (e.g., a user equipment) communicating via different independent links with different devices (e.g., transmit receive points (TRPs) or sets of TRPs). For example, the first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., a TRP) via a second link. In some scenarios, one link can indicate beam switching for at least one other link. In some scenarios, one link can indicate link recovery for at least one other link. In some scenarios, one link can indicate link failure for at least one other link.
