Abstract: Component carriers (CC)s that share components of a component chain are effected when components of the component chain are adjusted for one or more of the CCs. Systems switch CCs that share a component chain according to methods that alleviate drawbacks associated with sharing a component chain. In embodiments, CCs that share a component chain are identified as switching groups and are switched from default CCs to alternative CCs as a group to compensate for adjustments made in the shared component chain. Other aspects and features are also claimed and described.

Abstract: Aspects of the present disclosure provide techniques and apparatus for wireless communication. In one aspect, a method is provided which may be performed by a wireless device such as a user equipment (UE), which can be an Internet-of-things (IoT) device. The method generally includes monitoring a control channel in a narrowband of a system bandwidth for an uplink (UL) or a downlink (DL) grant, receiving interlaced UL and DL grants, sending or receiving information in response to the received interlaced UL and DL grants.

Abstract: In order to enable a UE receiving a narrowband signal transmitted using in-band resources to use the LTE reference signals to assist the UE in receiving the narrowband signal using an in-band deployment, a phase rotation employed by the base station may be fixed relative to a known reference position in time. An apparatus for wireless communication at a base station may determine a phase offset for a narrowband signal for transmission using wideband resources, the phase offset having a relationship to a reference point in time and transmit the narrowband signal using the determined phase offset. An apparatus for wireless communication at a UE may receive a narrowband signal having a frequency location within a wideband signal and rotate a symbol of the wideband signal by a per symbol phase offset having a relationship of the phase offset to a reference point in time.

Abstract: Due to the limited dimension of a NB that may be used by multiple users, as well as possible large coverage areas, timing offset estimation may be outside of NCP. The inaccuracy in the timing estimate can be improved by using more than one tone hopping distance for PRACH. An apparatus may then transmit a first and second tone of the PRACH at a first hopping distance from the first tone. The apparatus may then transmit a third tone of the PRACH and a fourth tone of the PRACH at a second hopping distance from the third tone. The second hopping distance may be greater than first hopping distance. The apparatus may also transmit an additional tone of the PRACH using a random hopping distance. A receiving apparatus may receive the transmitted PRACH and determine a phase estimation based on the sets of tones having different hopping distances.

Abstract: SE DESCRIBEN MÉTODOS, SISTEMAS Y DISPOSITIVOS PARA COMUNICACIÓN INALÁMBRICA. UNA ESTACIÓN BASE PUEDE DIFUNDIR UNA SEÑAL DE SINCRONIZACIÓN UTILIZANDO UNA PORCIÓN DE BANDA ESTRECHA DE UN ANCHO DE BANDA DE UNA CELDA. LA SEÑAL DE SINCRONIZACIÓN PUEDE INCLUIR UNA SECUENCIA REPETIDA DURANTE VARIOS PERÍODOS DE SÍMBOLOS UTILIZANDO UN CÓDIGO DE COBERTURA PARA SOPORTAR LA ADQUISICIÓN DE CELDAS DE EFICIENCIA ENERGÉTICA. UN EQUIPO DE USUARIO (UE) QUE RECIBE LA SEÑAL DE SINCRONIZACIÓN PUEDE DETERMINAR INFORMACIÓN DE FRECUENCIA Y TIEMPO PARA UNA CELDA AL REALIZAR UNA COMBINACIÓN PONDERADA Y ACUMULACIÓN DE PROCEDIMIENTOS DE AUTOCORRELACIÓN DE BAJA COMPLEJIDAD Y DE CORRELACIÓN CRUZADA EN LA SEÑAL DE SINCRONIZACIÓN. LOS PROCEDIMIENTOS DE CORRELACIÓN DE COMPLEJIDAD REDUCIDA PUEDEN HABILITARSE BASÁNDOSE EN EL USO DEL CÓDIGO DE COBERTURA Y UNA SECUENCIA DE BASE. EN ALGUNOS CASOS, LA CORRELACIÓN CRUZADA PUEDE REALIZARSE A MÚLTIPLES TASAS DE MUESTREO. EL USO DEL CÓDIGO DE COBERTURA DENTRO DE LA SEÑAL DE SINCRONIZACIÓN TAMBIÉN PUEDE SOPORTAR PROCEDIMIENTOS DE CORRELACIÓN QUE UTILIZAN ACTUALIZACIONES REPETITIVAS O RECURSIVAS, QUE PUEDEN PERMITIR UNA COMPLEJIDAD COMPUTACIONAL ADICIONAL REDUCIDA CON RESPECTO A OTROS PROCEDIMIENTOS DE BÚSQUEDA DE CELDAS.

Abstract: Various aspects of utilizing narrowband internet of things (NB IOT) communication are still under development. According to an aspect of the disclosure, the apparatus may be a user equipment (UE) using digital modulation for wireless communication via NB IOT communication in an unlicensed spectrum. The UE utilizes a plurality of downlink carriers in the unlicensed spectrum occupying at least a first minimum bandwidth by the plurality of downlink carriers and a plurality of uplink carriers in the unlicensed spectrum occupying at least a second minimum bandwidth with the plurality of uplink carriers. The UE performs communication using one or more of the plurality of downlink carriers and the plurality of uplink carriers.

Abstract: A user equipment (UE) may transmit a sounding reference signal (SRS) on a component carrier (CC) that is otherwise configured for downlink communications. Due to a carrier aggregation configuration or UE capability, the UE may need to retune certain components to transmit on the CC. If the SRS transmission, including the retuning time, collides with another transmission (e.g., in uplink or downlink) the UE may drop the SRS, drop the other transmission, or puncture the other transmission to facilitate the SRS transmission. The determination about a collision may depend on the retuning time, channel, or type of control information in the other transmission. In some cases, a UE may drop the other transmission if transmitting the SRS would prevent the UE from transmitting a demodulation reference signal, hybrid automatic repeat request (HARQ) feedback. In some cases, the determination may be based upon a prioritization and may also depend on a subsequent subframe.

Abstract: Methods, systems, and devices for wireless communication are described. Wireless communications systems as described herein may be configured to support several service types with different latency, reliability, or throughput rates or standards. One such service type may be referred to as high-reliability, low latency communication (HRLLC). Enhancements to improve HRLLC performance in coexistence with and as a complement to legacy service types, such as LTE are described. These include, for example, downlink and uplink control enhancements, channel state information (CSI) feedback enhancements, physical uplink shared channel (PUSCH) enhancements, and UL power control enhancements to support HRLLC.

Abstract: Standalone MBSFN cells may provide an improved user experience for an individual with a non-legacy UE since the bandwidth of that cell is mostly allocated to broadcasting streaming services. However, an individual with a legacy UE may be able to detect cell acquisition information associated with a standalone MBSFN cell but not to acquire standalone MBSFN cells. In order to solve this problem, the present disclosure provides various UE avoidance schemes that enable non-legacy UEs to acquire a standalone MBSFN cell and prevents legacy UEs from trying to acquire a standalone MBSFN only cell. The apparatus may receive cell acquisition information associated with an eMBMS standalone cell. The apparatus may detect a UE avoidance scheme based on a characteristic associated with the cell acquisition information. The apparatus may perform cell acquisition with the eMBMS standalone cell based on the characteristic.

Abstract: A base station (BS) may transmit, and a user equipment (UE) may receive, a physical broadcast channel, such as a narrowband physical broadcast channel (NB-PBCH). In an interference-limited scenario with synchronous cells in a network, repetitions of a symbol being transmitted for a first physical broadcast channel of a first cell may collide with repetitions of a symbol being transmitted for a second physical broadcast channel of a second cell. This may result in the UE being unable to recover symbols of a physical broadcast channel. In some aspects, the BS may transmit, and the UE may receive, a physical broadcast channel including bits processed using a first processing stage, such as using first scrambling sequences, and a second processing stage, such as using second scrambling sequences, to compensate for the interference, thereby ensuring that the UE can recover the symbols of the physical broadcast channel.
