An example method of geofencing for satellite communication performed by a UE, the method comprising obtaining a first region file comprising a plurality of regions, wherein each region of the plurality of regions is represented by one or more geo-polygons, wherein each region of the plurality of regions corresponds to a respective unique region identifier, and obtaining a first restriction status file comprising restriction status information regarding each region of the plurality of regions. The method further comprises receiving, from a server, a second restriction status file comprising a second set of region identifiers and corresponding restriction status information, determining a difference between the first set of region identifiers and the second set of region identifiers, and updating the first region file, the first restriction status file, or both based on the difference.

Geofencing for satellite communication in the absence of terrestrial networks

Certain aspects of the present disclosure provide techniques for time division duplex configuration override. A method that may be performed by a user equipment (UE) includes detecting a period during which a configuration of a first radio access technology (RAT) conflicts with a configuration of a second RAT for a frequency band; and overriding the configuration of the second RAT with the configuration of the first RAT for the period.

Time division duplex configuration override

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive one or more downlink grants while operating in accordance with a first receive state during a threshold number of transmission time intervals (TTIs). The UE may determine a weighting factor for each TTI within the threshold number of TTIs, where the determined weighting factors are based on a spectral efficiency (SPEF) of channel communications between the UE and a base station. The UE may sum a subset of the weighting factors to determine a transition determination value, and may transition from the first receive state to a second receive state based on evaluation of the transition determination value.

Advanced adaptive receivers based on spectral efficiency utilization

A user equipment (UE) may monitor a channel for wireless communication associated with a first radio access technology (RAT) during one or more of a first active duration or a first inactive duration. The UE may operate in a first power mode during the first inactive duration. The UE may monitor the channel for wireless communication associated with a second RAT during one or more of a second active duration or a second inactive duration. The UE may operate during the second inactive duration in one or more of the first power mode or a second power. The UE may operate according to the first mode or the second mode based on the monitoring of the channel associated with the first RAT and the second RAT.

Techniques for managing a radio transceiver chain for multiple radio access technologies

Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) may be scheduled to perform a first measurement or paging activity associated with a target cell operating according to a first target cell configuration that is different from a serving cell operating according to a first serving cell configuration of the UE. In some cases, the UE may determine that the UE has performed a previous measurement or paging activity associated with the target cell while being served by the serving cell, the cells operating according to previous cell configurations. The UE may compare at least one of the first and previous target cell configurations or the first and previous serving cell configurations, and may perform the first measurement or paging activity using a script, where the script is either reused or rebuilt based on comparing the cell configurations.

Script reuse during inter-frequency or inter-radio access technology measurements and paging

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may adaptively switch between hybrid automatic repeat request (HARQ) monitoring modes to support power savings. In a first HARQ skipping mode, the UE may transmit an uplink message corresponding to a HARQ identifier and may receive a positive acknowledgment (ACK) message in a HARQ monitoring occasion associated with the HARQ identifier. Upon receiving the ACK message, the UE refrains from monitoring a subsequent HARQ monitoring occasion associated with the HARQ identifier while in the first HARQ skipping mode (e.g., an aggressive HARQ skipping mode). The UE may periodically enter a periodic evaluation mode from the first HARQ skipping mode, in which the UE monitors a subsequent HARQ monitoring occasion after receiving an ACK message to check for false ACK messages. If a false ACK message is detected, the UE enters a first HARQ skipping prohibited mode.

Techniques for controlling hybrid automatic repeat request (HARQ)

Methods, systems, apparatuses, and devices are described for transmitting a measurement report during wireless communications. When, for example, a low-power period (e.g., CDRX OFF period) is scheduled to begin during a time defined by a measurement event timer (TTT timer), a UE may modify the low-power period. The low-power period may be modified based, at least in part on determining the low-power period of the UE will begin during a time defined by a measurement event timer, a duration of the measurement event timer, and a duration of the low-power period. Modifying the low-power period may include delaying the start of the low-power state until after transmission of the MR associated with the measurement event timer or skipping the low-power period altogether. The UE may transmit the MR based, at least in part, on the modification.

Priority management of a measurement event timer and low-power period

A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a user service description (USD) message. When a frequency indicated in the USD message is not a current frequency, the apparatus determines that a system information message is received, determines that the frequency indicated in the USD message is included in the system information message, determines that the frequency is a neighboring cell frequency, sets a priority of the frequency to a highest priority, and measures a signal strength of the frequency when the frequency is included in the system information message, performs a cell reselection determination procedure based on the signal strength of the frequency, performs cell reselection to the neighboring cell based on a result of the cell reselection determination procedure, and acquires the multicast service in the neighboring cell on the frequency.

EMBMS service activation and maintenance procedure in multi-frequency networks

Techniques for making measurements of cells in a wireless network are disclosed. In an aspect, cells to be measured are arranged into groups with different priorities. Groups with higher priority include stronger cells, which are measured more frequently and/or with more filtering to improve measurement accuracy. In one design, a user entity determines a plurality of groups of cells to make measurements. Each group includes at least one cell, and the plurality of groups have different priorities. The user entity determines a measurement interval for each of the plurality of groups of cells, with higher priority groups having shorter measurement intervals. The user entity schedules each cell in each group for measurement at least once (e.g., once) within the measurement interval for that group. The user entity makes measurements for the plurality of groups of cells based on the measurement interval for each group.

Measurement of cells arranged in groups of different priorities

In a wireless communication system, user equipment (UE) is provided, one or more set of rules are provided for the UE to handle the processing during a measurement gap. In some aspects, the gap measurement may be ignored. In some aspects, the processing is stored and handled at a later in time and gap measurements are performed. Depending on the system, the measurements performed during the gaps may be UE implementation dependent, wherein the UE determines whether to perform the measurement for a given gap. In some instances, the UE may not perform measurements during the gap, thereby giving priority to other processing, such as RACH processing. Depending on the type of processing required (DL-SCH, UL-SCH, TTI bundling, RACH or SR), the UE may store requests and process the measurements during the gap or ignore the gap measurement as if there were no gaps.

Processing measurement gaps in a wireless communication system

An apparatus and method for controlling idle mode radio measurements comprising: determining if a radio measurement is less than a radio threshold; determining a time duration in which the radio measurement is less than the radio threshold; determining if the time duration is greater than a time measurement threshold; and obtaining at least one other radio measurement from at least one base station which is not a serving cell.
