Provided are an uplink control receiving method and device, an uplink control sending method and device, a base station, and a user equipment. The method includes: configuring or specifying, for the receiving end, an orthogonal frequency division multiplexing (OFDM) symbol for transmitting the uplink control in a transmission unit, the location of the OFDM symbol in which the uplink control is located in the transmission unit and the location of an OFDM symbol in which uplink data is located in the transmission unit remaining continuous; and receiving the uplink control in the configured or specified OFDM symbol.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether an uplink communication for a first radio access technology (RAT) has been dynamically scheduled or semi-statically configured, wherein the UE is in a dual connectivity mode using the first RAT and a second RAT. The UE may identify an uplink subframe for transmission of the uplink communication based at least in part on whether the uplink communication has been dynamically scheduled or semi-statically configured, and based at least in part on a downlink-reference uplink-downlink configuration. The UE may transmit the uplink communication in the identified uplink subframe. Numerous other aspects are provided.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, in an inactive state, that uplink data is to be transmitted. The UE may determine whether a timing advance of the UE is valid. The UE may, if the timing advance is not valid, determine whether the uplink data satisfies a transport block size (TB S) threshold. The UE may, based at least in part on whether the uplink data satisfies the TB S threshold, selectively transmit the uplink data via an uplink random access channel (RACH) message or a configured uplink resource, or establish a radio resource control (RRC) connection for the uplink data. Numerous other aspects are provided.

Various embodiments may relate to small data transmission (SDT), which is also referred to herein as “early data transmission (EDT).” In particular, some embodiments disclosed herein include an indication of transport block size (TBS) and/or modulation and coding scheme (MCS) for Msg3 and/or MsgA PUSCH transmissions, and/or an indication of a fallback mechanism for SDT.

Provided is a method for a user equipment (UE). The UE generates a first information for the UE for transmission to a network device. The first information is associated with a small data transmission (SDT) procedure in an inactive state of the UE. The UE obtains a first configuration information from the network device. The first configuration information is determined with reference to the first information. The UE determines whether to perform the SDT procedure in the inactive state according to the first configuration information. The UE, in response to determining to perform the SDT procedure in the inactive state, performs the SDT procedure in the inactive state according to the first configuration information.

Methods, systems, and devices for wireless communications are described. Generally, a wireless device may select random access channel occasions (ROs) based jointly on synchronization signal block (SSB) measurements and cross-link interference (CLI) measurements. The base station may configure the wireless device with a set of SSB occasions during which to measure SSBs and a set of interference measurement occasions on which to measure CLI caused by other wireless devices. The wireless device may perform measurements on the received SSBs to determine channel quality for communications with the base station, and CLI measurements during the interference measurement occasions to determine whether CLI exceeds a threshold. The wireless device may then select a beam and an associated RO (e.g., a full duplex RO or a half duplex RO) on which to transmit the random access message using the selected beam.

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive an indication of a plurality of random access occasions for uplink message transmission to a base station. The UE may determine that a first portion of the plurality of random access occasions is unavailable for use by the UE as a result of the base station operating in a full duplex mode. The UE may select one or more random access occasions from a second portion of the plurality of random access occasions instead of from the first portion based at least in part on the determining. The UE may transmit a random access message to the base station during the one or more random access occasions from the second portion.

A method of transmitting a Random Access Channel (RACH) Occasion configuration to a terminal device and receiving a RACH preamble according to the RACH Occasion configuration. The RACH Occasion configuration comprises a first time resource indication identifying a first set of time resources in which the terminal device is allowed to transmit a RACH preamble according to a first random access procedure, a first frequency resource indication identifying at least a first set of frequency resources in which the terminal device is allowed to transmit the RACH preamble, a second time resource indication identifying a second set of time resources in which the terminal device is allowed to transmit a RACH preamble according to a second random access procedure, and a second frequency resource indication identifying at least a second set of frequency resources in which the terminal device is allowed to transmit the RACH preamble.

During operation, a mesh network access point (MAP) may communicate, via multiple mesh paths in a mesh network with the one or more root access points (RAPs), uplink packets or frames to or from at least two electronic devices. Notably, at a given time, the MAP uses a first mesh path in the mesh paths to communicate a first subset of the uplink packets or frames associated with a first electronic device in the two electronic devices and uses a second (different) mesh path in the mesh paths to communicate a second subset of the uplink packets or frames associated with a second electronic device in the two electronic devices. Moreover, the MAP may dynamically distribute the first electronic device or the second electronic device over the multiple mesh paths, e.g., based at least in part on one or more communication-performance metrics of the mesh paths and/or the mesh network.

The present disclosure provides a grant free uplink transmission method, the method is performed at a user equipment side, comprising: determining, according to configuration information for grant free uplink transmission received from a base station, a radio network temporary identifier GF-RNTI for grant free uplink transmission, and transmitting an uplink signal; and monitoring feedback from the base station in a downlink control channel by using the determined GF-RNTI. The present disclosure also provides a user equipment and a base station for grant free uplink transmission.
