The M-AP performs joint transmission to an STA by means of the first and second SAPs. The data frame is transmitted to the STA from the first and second S-APs by means of joint transmission.

Techniques that provide link auto-negotiation between a radio equipment controller (REC) and a radio equipment (RE) are described herein. In one embodiment, a method includes performing, by a proxy master, a Common Public Radio Interface (CPRI) Layer 1 (L1) link auto-negotiation with a RE to achieve a L1 synchronization between the proxy master and the RE at a link bit rate; communicating the link bit rate from the proxy master to a proxy slave; performing, by the proxy slave, a CPRI L1 link auto-negotiation with a REC to determine whether a L1 synchronization between the proxy slave and the REC is achieved, wherein if the L1 synchronization is achieved, the link bit rate is a common matching link bit rate achieved; and upon the common matching link bit rate being achieved, establishing a CPRI link between the REC and the RE using the common matching link bit rate.

A method and apparatus in a wireless communication system supporting shared spectrum channel access is provided. The method and apparatus comprises: receiving a set of downlink channels supporting the shared spectrum channel access; identifying, a window for SS/PBCH block transmission, a bitmap for SS/PBCH blocks (ssb-PositionsInBurst), and a parameter for QCL assumption Q; determining, based on the identified window for the SS/PBCH block transmission, the identified bitmap for the ssb-PositionsInBurst, and the identified parameter for the QCL assumption Q, a SS/PBCH block as one of: a first set of SS/PBCH blocks assumed to be transmitted by the BS, or a second set of SS/PBCH blocks not transmitted by the BS; determining a set of resources that is not available for at least one PDSCH as overlapped with the first set of SS/PBCH blocks; and receiving the at least one PDSCH based on resource other than the determined set of resources.

A method, a computer-readable medium, and an apparatus are provided for wireless communication including random access between a base station and a user equipment (UE). The UE transmits at least two first random access messages (Msg 1) to multiple transmission reception points (TRPs) of at least one cell using different resources for the multiple TRPs. The UE monitors for at least two second random access messages (Msg 2) from the multiple TRPs of the at least one cell using different resources for the multiple TRPs.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a receive time difference (RTD) between a first base station and a second base station based at least in part on the UE using a common beam to receive transmissions from the first base station and the second base station. The UE may transmit information indicating the RTD between the first base station and the second base station, wherein the transmissions from the first base station and the second base station may be scheduled based at least in part on the RTD between the first base station and the second base station. Numerous other aspects are provided.

An example apparatus includes: a memory; instructions in the apparatus; and a Bluetooth controller to execute the instructions to: enable circuitry to receive a synchronized transmission; determine if a synchronized transmission is received during a first duration; increment the first duration to a second duration as a result of not receiving the synchronized transmission during the first duration; and determine a third duration based on a determined difference in time between enabling circuitry to receive a synchronized transmission and receiving the synchronized transmission.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a wake up signal (WUS) to a base station in a WUS occasion that is configured for the WUS. The UE may transmit a communication to the base station after transmitting the WUS. Numerous other aspects are described.

Wireless communications systems and methods related to discovery signaling for sidelink communication are provided. In one aspect, a first user equipment (UE) transmits, to a second UE in a first slot and a first portion of a subband of a shared frequency band, a synchronization communication, where the synchronization communication indicates a location of a discovery signal in a second portion of the subband of the shared frequency band. The first UE also transmits, to the second UE in the first slot and in the second portion of the subband of the shared frequency band, the discovery signal.
