Abstract: Methods and apparatuses are provided that include counting devices for broadcast data services. The devices can be counted based on registrations received from the devices. This registration count can additionally or alternatively be used to determine whether further counting is desired. In addition, base stations can transmit counting requests to the devices using a paging message or other message such that idle mode devices can receive the counting requests. The idle mode devices can respond to the requests or send autonomous counting report by switching to an active mode for the purpose of responding or another purpose.

Abstract: In an aspect, a method assists with blind decoding of uplink control signals on a Physical Uplink Shared Channel (PUSCH) and Physical Uplink Control Channel (PUCCH). The method assists in determining the uplink control path in the event a user equipment (UE) misses an uplink grant and blind decoding occurs. It is determined whether an uplink acknowledgement, rank indicator, and/or channel quality indicator are found on a PUSCH. If not, it is determined whether a scheduling request is expected and whether special handling for the scheduling request is indicated. Depending on those determinations, and whether any decoding attempts for uplink signals are successful, either the PUSCH or PUCCH is selected as the uplink control path.

Abstract: Certain aspects of the present disclosure relate to a technique for implementing a cell site modem application message interface (CSM API) for a cell site of Long Term Evolution (LTE) wireless system.

Abstract: Methods and apparatus for uplink (UL) radio link monitoring (RLM) in a Long Term Evolution (LTE) heterogeneous network (HetNet) with enhanced inter-cell interference coordination (eICIC) are described. Various options are presented in an effort to transmit a sounding reference signal (SRS) of a user equipment device (UE) served by a Node B in the HetNet, avoiding both interference from UL transmissions from other UEs being served by neighboring Node Bs and collisions with the UE's own channel quality information (CQI) or physical uplink shared channel (PUSCH), for example.

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: Certain aspects of the present disclosure propose techniques for avoiding a disruption in synchronous hybrid automatic repeat request operation at system time rollover. The techniques define the behavior of a system before and after the system frame number (SFN) rollover point to ensure a known relationship between a hybrid automatic repeat request (HARQ) process identification number and system time.
