Abstract
Technology for communicating data to a user equipment (UE) is disclosed. Effective data rates may be identified, at a master evolved node B (MeNB), for the UE with respect to the MeNB and a secondary evolved node B (SeNB). A downlink split ratio for bearers of the MeNB and the SeNB to the UE may be determined based in part on the effective data rates for the UE. A first portion of data may be sent from the MeNB to the UE according to the downlink split ratio. A remaining portion of data may be sent from the MeNB to the UE via the SeNB according to the downlink split ratio, wherein the UE supports dual connectivity with the MeNB and the SeNB.
Claims25
A master evolved node B (MeNB) operable to communicate data to a user equipment (UE), the MeNB having circuitry configured to:
- identify effective data rates for the UE, the effective data rates including an effective data rate for an MeNB link between the UE and the MeNB and an effective data rate for a secondary evolved node B (SeNB) link between the UE and the SeNB;
- determine a downlink split ratio for bearers of the MeNB and the SeNB to the UE based in part on the effective data rates for the UE;
- send a first portion of data from the MeNB to the UE according to the downlink split ratio;
- and
- send a remaining portion of data from the MeNB to the UE via the SeNB according to the downlink split ratio, wherein the UE supports dual connectivity with the MeNB and the SeNB.
A user equipment (UE) that is configured to support dual connectivity, the UE having circuitry configured to:
- send information to at least one of a master evolved node B (MeNB) or a secondary evolved node B (SeNB), wherein the MeNB determines an uplink (UL) split ratio for the UE based in part on the information received from the UE;
- receive the uplink split ratio from a packet data convergence protocol (PDCP) layer the MeNB;
- and
- communicate data in the uplink from a PDCP layer in the UE to at least one of the MeNB or the SeNB according to the uplink split ratio, wherein the UE is configured to support dual connectivity with the MeNB and the SeNB.
A method for communicating data to a user equipment (UE), the method comprising:
- identifying, at a master evolved node B (MeNB), effective data rates for the UE with respect to the MeNB and a secondary evolved node B (SeNB);
- determining a downlink split ratio for bearers of the MeNB and the SeNB to the UE based in part on the effective data rates for the UE;
- sending a first portion of data from the MeNB to the UE according to the downlink split ratio;
- and
- sending a remaining portion of data from the MeNB to the UE via the SeNB according to the downlink split ratio, wherein the UE supports dual connectivity with the MeNB and the SeNB.
