Abstract: Systems and methodologies are described that facilitate searches for a cell in a wireless communication environment. A mobile device can employ a searcher that can detect timing information respectively associated with PSCs and cells to determine the cell with the highest correlation. The searcher can detect SSCs, which can include detecting associated phase information, to determine the SSC with the highest correlation, CP length, and/or other information to facilitate identifying a desired cell having the strongest signal to establish communication between the mobile device and the desired cell. PSCs respectively associated with cells can have different positions in the symbol sequences, and SSCs can respectively be phase shifted at different angles to facilitate detection and identification of a cell(s), where a PSC can be utilized as a phase reference by the associated SSC.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus, e.g., base station, determines a plurality of component carriers configured for a user equipment (UE) served by the apparatus. The plurality of component carriers includes a primary component carrier and a secondary component carrier. The primary component carrier may be a time division duplex (TDD) carrier having a same uplink:downlink configuration as a first cell at a neighboring base station, and the secondary component carrier may be a TDD carrier having a different uplink:downlink configuration as a second cell at the neighboring base station. The apparatus exchanges data with the UE according to an effective uplink-downlink subframe partition of the configured component carriers. The effective uplink-downlink subframe partition may be time varying and the apparatus may operate to limit interference due to the different TDD configurations at the serving and neighbor cells.

Abstract: To support cell search, multiple (e.g., two) synchronization transmissions are sent in a frame with non-uniform spacing. Information is conveyed via the non-equal distances between consecutive synchronization transmissions. Multiple levels of non-uniform spacing may be used to convey different types of information. In one design, the multiple synchronization transmissions are sent in different subframes of a frame, and each synchronization transmission is sent in one of multiple symbol periods in a respective subframe. The synchronization transmissions may be sent in non-evenly spaced subframes to convey frame boundary. One synchronization transmission may be sent in one of multiple possible symbol periods depending on the information, e.g., a particular group of cell IDs, being conveyed. The distances between synchronization transmissions may also be used to convey cyclic prefix length. A secondary synchronization transmission carrying a cell ID may be sent at a predetermined offset from one of the multiple synchronization transmissions.
Abstract translation: 为了支持小区搜索，在具有不均匀间隔的帧中发送多个（例如，两个）同步传输。 通过连续的同步传输之间的不相等的距离来传送信息。 可以使用多个级别的不均匀间距来传达不同类型的信息。 在一种设计中，多个同步传输在帧的不同子帧中发送，并且每个同步传输在相应子帧中的多个符号周期之一中发送。 可以以非均匀间隔的子帧发送同步传输以传送帧边界。 可以根据正在传送的信息（例如，特定的小区ID组）以多个可能的符号周期之一发送一个同步传输。 同步传输之间的距离也可用于传送循环前缀长度。 可以以多个同步传输之一的预定偏移量发送携带小区ID的辅同步传输。

Abstract: A backhaul quality is measured. One or more subsets of cell identifiers having a mapped backhaul quality that maps to the measured backhaul quality are identified. The one or more subsets have a set of cell identifiers associated therewith. A network is queried to indicate one or more cell identifiers in the identified subset of cell identifiers available for a user equipment (UE) relay. One of the one or more indicated cell identifiers is selected. If more than one subset of cell identifiers has a mapped backhaul quality that maps to the measured backhaul quality, first and second subsets having respective first and second mapped backhaul qualities are selected and the backhaul qualities are compared relative to a backhaul quality threshold. The mapped backhaul quality that most satisfies the backhaul quality threshold is identified for the network query.

Abstract: Methods, systems, and devices for wireless communication are described. A 5G device may decode a control channel transmission of a safety message in a vehicle-to-everything system during a first portion of a time period. The 5G device may identify, based at least in part on the decoding, a pool of resource blocks (RBs) that are available for the time period. The 5G device may select a subset of RBs from the available pool of RBs for a transmission during a second portion of the time period.

Abstract: Techniques are described for wireless communication. An orthogonal frequency-division multiple access (OFDMA) configuration of an uplink channel is identified for communications in an unlicensed radio frequency spectrum band. An OFDMA waveform is generated based on the identified OFDMA configuration. The OFDMA waveform is communicated in a signal in the unlicensed radio frequency spectrum band. A virtual cell identifier of a first base station may be associated with transmissions between the first base station and a first user equipment (UE). A set of common resource blocks may be identified for transmission of a demodulation reference signal (DM-RS) between the first base station and the first UE. A configuration of an uplink channel may be dynamically selected for uplink communications in an unlicensed radio frequency spectrum band. A waveform may be generated based on the selected configuration. The waveform may be communicated in a signal in the unlicensed radio frequency spectrum band.

Abstract: A method of wireless communication includes configuring a small cell with activation parameters. The activation parameters include a new carrier type having a reduced periodicity. The method also includes configuring a UE with time restricted measurements. The time restricted measurements correspond to the new carrier type and the reduced periodicity. The method further includes receiving small cell signal measurements from the UE and initiating an activation sequence in response to the small cell signal measurements.
