Abstract:
Certain aspects of the present disclosure propose methods and apparatus to transmit information about number of active UEs in a cell (e.g., pico cell) that need protection to an interfering cell (e.g., a macro cell). The information may be transmitted in a resource status update message. The active users may be defined as users whose downlink performance and/or quality of service are limited by the available number of protected resources.
Abstract:
Certain aspects of the present disclosure propose methods for protecting channel quality indicator (CQI) modulation symbols in a subframe (e.g., a localized frequency division multiplexing (LFDM) subframe). For some aspects, a timing adjustment method may be utilized to adjust time of a UE with respect to an eNodeB. The timing adjustment method may introduce a positive time offset to be used for reducing time mismatch between the UE and the eNodeB. In another aspect, a buffer may be used at the eNodeB to store symbols received by the eNodeB before removing the cyclic prefix information from the subframe. The eNodeB may use the stored symbols and an artificial time delay to ensure that the CQI information is protected. For some aspects, the CQI modulation symbols may not be located at the beginning of an LFDM symbol.
Abstract:
Aspects of the present disclosure relate to joint support for UEs capable of communicating data of a same bearer on first and second RATs simultaneously and UEs not capable of communicating data of a same bearer on the first and second RATs simultaneously. An eNB of a first RAT may configure radio bearers of different types for communication with a UE scapable of communicating via a first RAT and a second RAT. The eNB may select one or more of the radio bearers for routing packets to the UE via at least one of the first or second RAT, wherein the selecting is based at least in part on whether the UE is capable of communicating data of a same bearer on the first and second RATs simultaneously. The eNB may communicate with the UE using the selected radio bearers.
