Abstract: A method can include sending, by a first wireless node to a second wireless node, multiple packets, the multiple packets being associated with multiple sequence numbers; sending a poll to the second wireless node, the poll requesting indications of whether the multiple packets were successfully received; setting a polling sequence number to a highest sequence number associated with the multiple packets sent by the first wireless node when the first wireless node sent the poll; starting a poll retransmission timer; receiving a status report from the second wireless node, the status report including a negative acknowledgment sequence number and an acknowledgment sequence number, the negative acknowledgment sequence number being greater than the acknowledgment sequence number; and based on the negative acknowledgment sequence number being equal to or greater than the polling sequence number, reinstating the poll retransmission timer.

Abstract: Methods and apparatus, including computer program products, are provided for dual connectivity. In one aspect there is provided a method. The method may include switching, by a user equipment, between a first carrier associated with a first base station and a second carrier associated with a second base station, wherein the switching is performed based on at least a configuration defining when to perform the switching; and indicate an extension of a time allocated by the configuration at the first base station. Related apparatus, systems, methods, and articles are also described.

Abstract: Systems, methods, apparatuses, and computer program products for enhancing the setup of carrier aggregation (or dual connectivity or multi connectivity or stand-alone LTE/LTE-like on unlicensed band or LAA or LTE-WLAN aggregation) from IDLE mode (or semi-idle or semi-connected or suspended state) are provided. One method includes providing an indication, to at least one UE, of (or configuring the UE with) potential inter-frequency carriers that the UE should measure during IDLE mode (or during semi-idle or semi-connected or suspended state) for potential SCells. The method may further include during or after RRC connection establishment, receiving an indication from the at least one UE that it has inter-frequency carrier(s) and/or SCell measurement results available, and based on the received measurement results, configuring carrier aggregation (or dual connectivity or multi connectivity or LAA or LTE-WLAN aggregation) without further measurements and activating the SCell.

Abstract: Disclosed is a User Equipment UE, which establishes connection with a macro eNB (or master eNB) and a small cell eNB (or secondary eNB), measures channel quality (CQI) of a signal received from the small cell eNB, derives a second channel quality based on the measured channel quality of the signal received from the small cell eNB, transmits information associated with the measured channel quality of the signal to the small cell eNB and transmits information associated with the second channel quality to the macro eNB.

Abstract: A network configuration and process are disclosed in which a user equipment preserves its physical uplink control channel resources (PUCCH) in connected mode when so instructed by the network upon expiration of a time alignment timer. Upon re-initiation of network messaging the network passes information to the user equipment during random access signalling to re-use the physical uplink control channel resources.
