A method and apparatus for communication in a network of WLAN overlapping basic service set (OBSS) are disclosed. A station or an access point may indicate its interference reporting and inter-BSS coordination capabilities in a message. At least one of quality of service (QoS) settings, transmission opportunity (TXOP), restricted access window (RAW) or beacon subinterval schedules, or traffic indication map (TIM) or uplink access window assignment may be coordinated. The station may receive a request for interference measurements on the basic service set (BSS) of the station or neighboring BSSs that the station can overhear. The station may transmit an interference measurement report to an access point. The coordination may be performed based on the interference measurement report. Furthermore, STAs may transmit channel or sector preferences to APs and receive channel or sector assignments.

A wireless transmit/receive unit (WTRU) may initiate a random access. The WTRU may determine whether to select a first random access channel (RACH) procedure or a second RACH procedure for the random access. The first RACH procedure may be a legacy RACH procedure. The second RACH procedure may be an enhanced RACH (eRACH) procedure. The WTRU may determine whether to select the first RACH procedure or the second RACH procedure based at least on a type of uplink data to be transmitted. When the second RACH procedure is selected, the WTRU may determine at least one physical random access channel (PRACH) resource associated with the second RACH procedure. The WTRU may determine a preamble sequence associated with the second RACH procedure. The WTRU may determine a data resource for the uplink data. The WTRU may send a RACH transmission that includes the preamble sequence and the uplink data.

A method performed by a wireless device is described herein. The wireless device operates in a wireless communications network. The wireless device provides a message to be sent to a network node operating in the wireless communications network. The message is a first scheduled message to be sent to the network node in a random access procedure. The message comprises a first indicator of a type of the message. The type of message has: a) a fixed size SDU, and b) a one byte header comprising the first indicator and lacking a second indicator of a length of a payload. The wireless device also initiates sending the provided message to the network node. Also described is a method performed by the network node receiving and initiating processing the message, based on the first indicator.

User equipment includes a transmission unit that performs uplink transmissions to a base station apparatus via a plurality of uplink carriers; and a control unit that changes a transmission power value of a random access channel to be transmitted with one or more of the plurality of uplink carriers when priority levels are assigned to the respective uplink transmissions on the plurality of uplink carriers; wherein, when the transmission unit fails to transmit a random access preamble with the transmission power value of the random access channel that is changed by the control unit and the transmission unit retransmits a random access preamble, the control unit changes transmission power control of the random access preamble to be transmitted from normal transmission power control.

A method and apparatus are provided, in which information of a feedback time for transmitting a feedback message from the user equipment for a physical shared channel message is received (402). A maximum allowed feedback time delay associated with the feedback message for the physical shared channel message is determined (404). A physical channel occasion available to be used by the user equipment for transmitting the feedback message is identified (406). The feedback message is transmitted when the identified available physical channel occasion, which is available to be used for the feedback message, allows for the feedback message to be transmitted within the maximum allowed feedback time delay, otherwise the feedback message is not transmitted, when the identified available physical channel occasion does not allow for the feedback message to be transmitted within the maximum allowed feedback time delay (408).

Configured grant (CG) channel occupancy time (COT) sharing procedure is disclosed. A user equipment (UE) sharing a COT may indicate in the uplink control indicator (UCI) the remaining COT duration, an offset indication identifying where the uplink transmission is expected to end, and a channel access priority class (CAPC) which may be used by the base station to determine which type of data may be included in downlink transmissions in the shared COT. Where the energy detection (ED) threshold has not been configured for COT sharing, the UE may reduce the information included in the UCI. The base station may alternatively configured which information for the UE to include in the UCI for potential COT sharing. The COT sharing information may further be compressed by coding such information into tables or leveraging knowledge of transmission characteristics, such as configured end points.

A UE may receive, from a base station/TRP, a configuration for a beam pair including an UL beam and a DL beam and transmit a RACH message via the UL beam while receiving DL information via the DL beam. The UE and/or the base station/TRP may be configured to operate in a FD mode. In aspects, the UE may transmit a RACH preamble based on a first mode of transmission. After a threshold time delay measured from the transmission of the RACH preamble, the UE may retransmit the RACH preamble based on a second mode of transmission. The second mode of transmission may be a same mode of transmission or a different mode of transmission from the first mode of transmission. Each mode of transmission may be based on one or more of TDM, FDM, or SDM.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus may transmit, to a base station, a request to transmit uplink control information (UCI), for a first physical uplink control channel (PUCCH) group that includes a primary cell (PCell) and for a second PUCCH group that includes a PUCCH secondary cell (SCell), via the PUCCH SCell. The apparatus may receive, from the base station, an indication of whether the request is rejected or approved. Numerous other aspects are described.

A UE is provided with a dedicated preamble for use in a two-step random access procedure, as well as dedicated, contention-free PUSCH transmission resources for the PUSCH part of msgA. In one embodiment, the base station transmits a partial PUSCH msgA configuration to the UE using dedicated RRC signaling. In another embodiment, the base station transmits a resource index to the UE indicative of a dedicated PUSCH resource for a msgA transmission via dedicated RRC signaling.

Systems, apparatuses, and methods are described for wireless communications. A wireless device may initiate a random access process comprising transmitting a transport block comprising data of a CCCH logical channel. The CCCH logical channel may be associated with an identifier indicating that the wireless device is a reduced capability wireless device.
