摘要： Techniques for access terminal radio link monitoring on a shared communication medium are disclosed. In an aspect, an access terminal detects a missed reference signal event associated with a radio link established on the shared communication medium, wherein detecting the missed reference signal event comprises determining that the access terminal did not detect a reference signal for measuring a quality of the radio link transmitted during a reference signal configuration window, assigns an error metric to the missed reference signal event based on reference signal monitoring capabilities of the access terminal, and triggers a radio link failure based on the assigned error metric. In an aspect, the missed reference signal event may be a missed Discovery Reference Signaling (DRS) event, the error metric may be a Block Error Rate (BLER) weight, and the reference signal for measuring the quality of the radio link comprises a Cell-specific Reference Signal (CRS).

摘要： A method of wireless communication includes adjusting a channel quality indicator (CQI) to compensate for coexistence interference experienced between communication resources (such as an LTE radio and a Bluetooth radio). The CQI may be set to zero, falsely indicating to a serving enhanced NodeB that a UE is out of range, thereby creating a gap in LTE operation that may be used by an alternate radio access technology. To compensate for fluctuating interference, the CQI may be adjusted to incorporate average coexistence interference over a period of time. Alternatively, the CQI at a time may incorporate coexistence interference regardless of whether interference is experienced at that specific time. A CQI value may also be boosted to compensate for a CQI backoff. CQI may be adjusted to avoid a spiral of death effect.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine an actual power delay profile (PDP) associated with a channel between the UE and a base station, wherein the actual PDP indicates an averaged power level of the channel over a period of time. The UE may determine whether a channel estimation mode switching event is satisfied. The UE may switch, based at least in part on the channel estimation mode switching event being satisfied, between a first channel estimation mode based at least in part on the actual PDP and a second channel estimation mode based at least in part on a template PDP. Numerous other aspects are described.

摘要： Some techniques and apparatuses described herein protect components of a user equipment (UE), such as a low noise amplifier (LNA), from internal interference. For example, the LNA may be disconnected from a receive chain during periods of high internal interference, and may be reconnected to the receive chain during periods of low internal interference. Furthermore, some techniques and apparatuses described herein improve performance by adjusting operations of the UE to account for and/or offset increased internal interference due to a receive chain that does not include a surface acoustic wave (SAW) filter to remove unwanted radio frequency signals. For example, one or more operations of a baseband processor may be modified to account for the increased internal interference. Additionally, or alternatively, reporting of channel state information may be modified to account for increased internal interference of the UE. Additional details are described herein.

摘要： Aspects described herein relate to decoding downlink control information (DCI) based on multiple DCI sizes. A first hypothesis of multiple hypotheses for decoding a communication received in a control channel search space, wherein the multiple hypotheses are based on different corresponding DCI sizes can be determined. The communication received in the control channel search space can be decoded based on the first hypothesis. For each of the multiple hypotheses and based on the different corresponding DCI sizes, information bits can be extracted from the communication as decoded. For each extracting of the information bits, cyclic redundancy check (CRC) can be performed based on one of the different corresponding DCI sizes to determine whether extracting of the information bits yields DCI.

摘要： Aspects of the present disclosure provide techniques for the user equipment (UE) to select a power management mode from a plurality of power management modes supported by the UE based on decoding of a portion of the downlink subframe. For example, when the UE receives a subframe from a base station, the UE may decode a control channel region of the subframe to determine whether the subframe includes a channel grant allocated to the UE. If no channel grant is included in the subframe, the UE may select a power management mode for the UE from the plurality of power management modes supported by the UE that maximizes the UE's sleep opportunities while balancing the deficient performance costs.

摘要： Methods and apparatus for RF channel selection in a multi-frequency network. A method includes identifying selected local operations infrastructures (LOIs) and their neighboring LOIs, generating a neighbor description message (NDM) that identifies the selected LOIs and their neighboring LOIs and associates a descrambling sequence identifier with each RF channel of the selected LOIs and their neighboring LOIs, and distributing the NDM over the selected LOIs. An apparatus includes a message decoder to receive an NDM that identifies RF channels of a first LOI and neighboring LOIs, and wherein each RF channel is associated with a descrambling sequence identifier, and processing logic to detect content acquisition failures, determine a list of RF channels and their associated LOIs that carry desired content, and select a selected RF channel that is associated with a selected LOI that carries the most additional content among the associated LOIs.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may determine, based at least in part on two or more measurements on a channel taken at different points in time, that the channel is classified as static. The wireless communication device may perform at least one optimization based at least in part on determining that the channel is classified as static. For example, the at least one optimization may include modifying a channel state feedback procedure, reducing a periodicity associated with a measurement gap, modifying a filtering associated with measurements of the channel, reducing a threshold associated with beam switching, and/or refraining from performing at least one filtering at a radio frequency receiver of the wireless communication device. Numerous other aspects are described.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure a first energy level of a demodulation reference signal (DMRS). The UE may measure a second energy level of at least one of a tracking reference signal (TRS) or a synchronization signal block (SSB). The UE may determine, based at least in part on the first energy level and the second energy level, a DMRS signal-to-noise ratio (SNR). The UE may perform, based at least in part on the DMRS SNR, channel estimation for a physical channel associated with a communication to determine an estimated channel. The UE may perform, based at least in part on the estimated channel, demodulation processing for the communication. Numerous other aspects are described.
