    Abstract: Methods, systems, and devices related to mobility management (e.g., reducing transmission delay and interference, and/or increasing transmission reliability) using the unlicensed spectrum are described. In one representative aspect, a method for wireless communication includes receiving, at a wireless communication node, a first message from a mobile device requesting a reestablishment of a network connection; transmitting, from the wireless communication node, a second message to the mobile device, the second message including information for reestablishing and reconfiguring the network connection; and receiving, at the wireless communication node, a third message from the mobile device acknowledging at least one of (1) completing a reestablishment of the network connection, or (2) completing a reconfiguration of the network connection.

    Abstract: One or more devices, systems, and/or methods for facilitating access to an uplink carrier are provided. For example, information corresponding to a plurality of uplink carriers may be received from a wireless node. An uplink carrier may be selected from the plurality of uplink carriers based upon the information. A request to access the uplink carrier may be transmitted to the wireless node.

    Abstract: Techniques are described to improve the transmission and reception of access signals such as synchronization signal block (SSB), system information, or paging message. As an example, a wireless communication method is disclosed where a network node, such as a base station, determines a first set of transmission times and/or a second set of transmission times to transmit access signals. The network node transmits the access signals over a wireless channel using the first set of transmission times and/or the second set of transmission times. The access signals can include system information, paging message, or synchronization signal block.

    Abstract: Provided are a codebook feedback method, a codebook feedback apparatus, a device, and a storage medium. The codebook feedback method includes: triggering, according to control information (CI), a hybrid automatic repeat request-acknowledgement (HARQ-ACK) codebook of a data channel group to perform feedback, where the CI includes at least one of: information of new feedback indication (NFI) corresponding to one or more data channel groups, a data channel group identifier and a group index corresponding to a currently scheduled data channel, or, a total downlink assignment index (T-DAI) corresponding to one or more data channel groups.

    Abstract: One or more devices, systems, and/or methods for facilitating transmission of a configuration corresponding to an uplink carrier are provided. The configuration may be transmitted to a node. The configuration may be used to identify the uplink carrier. The node may access the uplink carrier responsive to receiving an add instruction. The node may release the uplink carrier responsive to receiving a delete instruction.
