This application discloses a resource multiplexing method and apparatus. In this application, a first node receives first configuration information sent by a second node, where the first configuration information includes first guard interval information associated with a first timing mode of an MT. The first node receives second configuration information sent by the second node, where the second configuration information includes second guard interval information associated with a second timing mode of the MT. Guard interval information configured by the second node is associated with different timing modes, so that the first node can obtain the guard interval information corresponding to the different timing modes, to improve flexibility of resource multiplexing performed on an access link and a backhaul link.

A system includes a plurality of remote units; a centralized unit communicatively coupled to the plurality of remote units via a fronthaul network; and an entity that performs deep packet inspection. The centralized unit transmits sets of data to the plurality of remote units across the fronthaul network in packets, each of the sets of data mapped to at least one of the plurality of remote units and each of the packets including a respective indicator indicating each remote unit the associated packet is intended for, wherein each indicator comprises a plurality of bit positions where each bit position is mapped to a different one of the plurality of remote units. The entity performs the deep packet inspection on the packets to determine each remote unit the packets are intended for and communicate each packet to each remote unit the packet is intended for over the fronthaul network.

A method for handling contention based data transmission (CBDT) in a wireless communication network is disclosed. The method includes: allocating CBDT resource blocks to a plurality of user equipment (UEs); receiving data bits and control bits on one or more resource blocks among the allocated CBDT resource blocks from a group of UEs among the plurality of UEs; determining whether each of the received data bits and control bits is decoded successfully; transmitting a negative acknowledgment message to each UE in the group of UEs based on determining that the received control bits are decoded successfully, and the received data-bits are not decoded successfully; and storing the data-bits which are not decoded successfully in a hybrid automatic repeat request (HARQ) buffer.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE via reflection by one or more passive devices, a first reference signal (RS) that is based at least in part on a shared first key that corresponds to a configuration of the one or more passive devices. The first UE may receive, from the second UE via reflection, a second RS that is based at least in part on the first key. The first UE may generate a second key based at least in part on a measurement of the second RS. The first UE may transmit a positioning reference signal that is based at least in part on the second key and that is associated with a measurement of a range between the first UE and the second UE. Numerous other aspects are described.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may identify a first sidelink (SL) bandwidth part (BWP) of the first UE and a second SL BWP of a second UE. In some aspects, the first UE may adjust the first SL BWP based at least in part on a partial overlap between the first SL BWP and the second SL BWP. In some aspects, the first UE may transmit, to the second UE based at least in part on the partial overlap between the first SL BWP and the second SL BWP, an indication associated with adjusting the second SL BWP. Numerous other aspects are described.

A base station may generate first configuration information to configure a first user equipment (“UE”) to operate using a first bandwidth within a wideband carrier of a cell, generate second configuration information to configure a second UE to operate using a second bandwidth within the wideband carrier of the cell, and cause transmission of the first and second configuration information to the first and second UEs, respectively. The base station may configure the first and second UEs based upon capabilities received from each UE, respectively.

A base station includes a transmitter configured to transmit a downlink control information to a user equipment, the downlink control information being generated based on one of (1) a first uplink allocation information indicating a first frequency block corresponding to a first plurality of subcarriers which are contiguous in frequency and (2) a second uplink allocation information indicating a second frequency block corresponding to a second plurality of subcarriers which are contiguous in frequency and a third frequency block corresponding to a third plurality of subcarriers which are contiguous in frequency, the second frequency block and the third frequency block being separated in frequency.

The user equipment (UE) configured to receive a physical broadcast channel (PBCH) in a first bandwidth portion of a cell having a cell bandwidth, the PBCH having a master information block (MIB), the MIB having a carrier flag and an indication of a second bandwidth portion of the cell. The UE is further configured to receive the second bandwidth portion of the cell based on a first value on the carrier flag and recover control information from the second bandwidth portion.

The present disclosure provides a method and a device in wireless communication. In one embodiment, the UE first receives a first signaling, then receives a second signaling, and finally receives a first radio signal on target time-frequency resources; wherein the target time-frequency resources comprise time-frequency resources among second time-frequency resources other than first time-frequency resources, and the second signaling is used for determining whether the target time-frequency resources comprise the first time-frequency resources and the second time-frequency resources. The present disclosure makes effective use of the remaining time-frequency resources that transmit control information in a time interval less than 1 millisecond, thus improving resource utilization.

Aspects of the disclosure relate to wireless communication over a shared spectrum carrier utilizing a broadcast, common control channel. The broadcast control channel may be multiplexed with a unicast control channel. Further, a scheduling entity may allocate a semi-static set of resources for the broadcast control channel, providing a shared search space on the shared spectrum carrier. The resource allocation for the shared search space may be based on one or more parameters, which may be cell-specific parameters. This shared search space may include resources distributed across the shared spectrum carrier, or a contiguous set of resources that spans only a portion of the carrier. The broadcast control channel may be configured for high reliability, and may carry time-critical control information relating to access control for the shared spectrum carrier. Other aspects, embodiments, and features are also claimed and described.
