Adaptations of dual connectivity operation to ue capability

Abstract

A user equipment (UE) is configured by a Master enhanced NodeB (MeNB) for operation with dual connectivity to a Secondary eNB (SeNB) to transmit acknowledgement information when the UE is power limited and for a respective eNB to determine a UE power limitation. The UE, the MeNB, and the SeNB adjust operation according to a partitioning of a UE capability between the MeNB and the SeNB. The UE capability can be a transmission power, a soft buffer size, a reception or a transmission of a number of data transport block bits, or a number of decoding operations.

What is claimed is: 
     
         1 . A method, comprising:
 receiving, by a master node from a secondary node, a request for a first number of physical downlink control channel (PDCCH) candidates; and   transmitting, from the master node to the secondary node, an assignment for a second number of PDCCH candidates.   
     
     
         2 . The method of  claim 1 , wherein:
 the PDCCH candidates are for scheduling a user equipment (UE) on the secondary node, and   the UE operates in dual connectivity with the master node and the secondary node.   
     
     
         3 . The method of  claim 1 , further comprising:
 transmitting, from the master node to the secondary node, a configuration for a discontinuous reception (DRX) cycle.   
     
     
         4 . The method of  claim 1 , further comprising:
 receiving, by the master node from the secondary node, a configuration for a discontinuous reception (DRX) cycle.   
     
     
         5 . The method of  claim 1 , wherein:
 a first discontinuous reception (DRX) cycle is configured by the master node to a user equipment (UE),   a second DRX cycle is configured by the secondary node to the UE, and   the UE operates in dual connectivity with the master node and the secondary node.   
     
     
         6 . The method of  claim 1 , further comprising:
 receiving, by a master node from a secondary node, a request for a first power; and   transmitting, from the master node to the secondary node, an assignment for a second power.   
     
     
         7 . The method of  claim 1 , further comprising:
 transmitting, from the master node to the secondary node, a configuration for measurement gaps.   
     
     
         8 . The method of  claim 7 , wherein:
 the measurement gaps are configured to a user equipment (UE) on the master node, and   the UE operates in dual connectivity with the master node and the secondary node.   
     
     
         9 . A network node, comprising:
 a receiver configured to receive a request for a first number of physical downlink control channel (PDCCH) candidates; and   a transmitter configured to transmit an assignment for a second number of PDCCH candidates.   
     
     
         10 . The network node of  claim 9 , wherein:
 the network node is a master node, and   the master node communicates with a secondary node.   
     
     
         11 . The network node  claim 10 , wherein:
 the transmitter is further configured to transmit a configuration for a discontinuous reception (DRX) cycle.   
     
     
         12 . The network node  claim 10 , wherein:
 the receiver is further configured to receive a configuration for a discontinuous reception (DRX) cycle.   
     
     
         13 . The network node  claim 10 , wherein:
 the receiver is further configured to receive a request for a first power, and   the transmitter is further configured to transmit an assignment for a second power.   
     
     
         14 . The network node  claim 10 , wherein:
 the transmitter is further configured to transmit a configuration for measurement gaps.   
     
     
         15 . A network node, comprising:
 a transmitter configured to transmit a request for a first number of physical downlink control channel (PDCCH) candidates; and   a receiver configured to receive an assignment for a second number of PDCCH candidates.   
     
     
         16 . The network node of  claim 15 , wherein:
 the network node is a secondary node, and   the secondary node communicates with a master node.   
     
     
         17 . The network node  claim 15 , wherein:
 the receiver is further configured to receive a configuration for a discontinuous reception (DRX) cycle.   
     
     
         18 . The network node  claim 15 , wherein:
