摘要:
A method and system for access and uplink power control for a wireless system having multiple transmit points. In one aspect, a method at a user equipment operating in a wireless network having a plurality of transmission points including a macro evolved Node B (‘eNB’) and at least one low power node (‘LPN’) having transmit power lower than that of the macro eNB, the method finding, at the user equipment, at least one reference transmission point, the finding utilizing at least one of a calculation at the user equipment and a message from a network element; and performing, by the user equipment, uplink power control based on the at least one reference transmission.

A method and system for access and uplink power control for a wireless system having multiple transmit points. In one aspect a method operating in a wireless network having a plurality of transmission points (TP) including a macro evolved Node B (eNB) and at least one low power node (LPN) having transmit power lower than that of the macro eNB, the method detecting, by the user equipment, a transmission point having a lowest path loss to the user equipment; and transmitting, by the user equipment, a physical random access channel (PRACH) preamble on a PRACH directed to the transmission points having the lowest path losses.
摘要:
A method for indicating a precoding granularity value. The method includes an access node performing at least one of dynamically signaling the precoding granularity value in downlink control information, semi-statically signaling the precoding granularity value through high-layer signaling, and implicitly signaling the precoding granularity value through a link with at least one parameter that the access node transmits for another purpose.

Embodiments of the present disclosure describe methods, apparatuses, and systems for managing bearers in a wireless communication system. In some embodiments, an apparatus, to be employed by a user equipment (UE), may comprise a communication module to: communicate with a core network on a first bearer through a master evolved Node B (MeNB); receive, from the MeNB, a first message of reconfiguring a radio resource control (RRC) connection to establish a second bearer between the UE and the core network and through a secondary eNB (SeNB); synchronize, in response to the message, with the SeNB in order to establish the second bearer; and communicate with the core network on the second bearer through the SeNB, and continue communicating with the core network on the first bearer through the MeNB.
摘要:
Embodiments of the present disclosure are directed toward devices and methods for fast radio link recovery in cellular networks. In one embodiment, the signal strength of the serving cell is compared to the signal strength of a target cell, and a radio link failure (RLF) timer is terminated or shortened based on the comparison. Alternatively, a second shorter timer may be used as opposed to modifying the current timer. In some embodiments, the modification of RLF timers may be triggered by the start of a measurement trigger timer. This may allow a user equipment to more quickly establish a connection with a target cell in situations where radio link failure or handover failure are likely to occur. In some instances, the parameters for terminating or shortening the radio link failure timer, or starting an additional timer, may be provided to the user equipment by a network.
