Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a base station may identify a burst periodicity for communication bursts over one or more cells, such as secondary cells (SCells) in accordance with a multi-carrier communication scheme. The UE and the base station may determine a cell dormancy pattern for switching the SCells between an active state and a dormant state based on the burst periodicity. The base station and the UE may use one or more bandwidth parts (BWPs) for communications and may configure the UE to perform BWP switching over the SCell during the dormancy state switching operation. The base station and the UE may communicate the bursts while the SCells are in the active state and may switch the SCells between the active state and the dormant state based on the cell dormancy pattern.

Cell dormancy techniques for traffic

Methods and apparatuses for communicating in a wireless communication network are disclosed. For example, one method includes determining, by a first access point, a polling schedule for communicating with one or more wireless stations on a first wireless communication channel, the polling schedule for a second access point on a second wireless communication channel. The method further includes transmitting, by the first access point, on the first wireless communication channel, transmission information to the one or more wireless stations, wherein the transmission information comprises information for the one or more wireless stations to receive a transmission from the second access point on the second wireless communication channel. The method further includes transmitting, by the first access point, on the first wireless communication channel, one or more packets to at least one of the one or more wireless stations in accordance with the polling schedule.

Methods and apparatus for multi-channel medium access control protocol

Systems and methods are provided to improve roaming performance and to minimize disruptions in connectivity. When roaming between a source AP and a target AP, the device determines whether the APs employ different gateways, such as through an ARP exchange. If the source and target APs have different gateways, a DHCP exchange is used to renew the IP address of the device to restore network connectivity.
