Abstract: Various aspects related to frequency biasing to compensate for frequency variations caused by Doppler shift in V2V communication systems are described. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus, e.g., a UE, may be configured to determine a velocity of the apparatus, and determine a frequency biasing adjustment based on the determined velocity of the apparatus. The apparatus may be further configured to communicate with UE based on an adjusted carrier frequency determined based on a carrier frequency and the determined frequency biasing adjustment. In some configurations, a driving environment of the apparatus maybe considered, and the frequency biasing adjustment is determined further based on the determined driving environment.

Abstract: In wireless communication systems that support 5G or NR protocols, subframes used for communication may have different numerology options. Numerology options may refer to the characteristics of the subframe such as a tone spacing within each symbol of the subframe, a symbol duration for each symbol of the subframe, a number of symbols in the subframe, etc. A subframe may include a control channel (e.g., the PDCCH) and a data channel (e.g., the PDSCH). In an aspect, the control channel and the data channel within the subframe may have different numerologies. As such, a need exists to signal the numerology of the subframe to users and to determine whether and how to multiplex the control channel and the data channel into the subframe.

Abstract: Various aspects related to techniques for harmonization between common reference signal (CRS) and demodulation reference signal (DM-RS) based transmission modes (TMs) in unlicensed spectrum are described. In one aspect, a downlink/uplink (DL/UL) subframe configuration may be signaled for each subframe. Information provided by the DL/UL subframe configuration may indicate whether the respective downlink subframe is a single-frequency network (MBSFN) subframe (associated with DM-RS-based TM) or a non-MBSFN subframe (associated with CRS-based TM). In another aspect, periodic as well as aperiodic channel state information (CSI) reporting requests may be supported. In yet another aspect, discontinued reception (DRX) wake ups for unlicensed carriers may be explicitly or implicitly indicated to a user equipment (UE) via a carrier in a licensed spectrum.

Abstract: A method, an apparatus, and a computer-readable medium for delivering content to end user via shared broadcast are provided. The apparatus may be a UE that determines to acquire a MBMS service. The UE tunes to a frequency provided by a first MNO to which the UE is not a subscriber in order to receive the MBMS service via a carrier shared by the first MNO and at least one other MNO. The UE receives the MBMS service on the frequency via the carrier shared by the first MNO and the at least one other MNO. The shared carrier may have a common SFN timing with respect to the first MNO and the at least one other MNO. The shared carrier may include a shared MBMS SDL carrier.

Abstract: Certain aspects relate to methods and apparatus for latency reduction for UEs in a RRC connected mode. During contention-based uplink access by groups of UEs within a subframe, an eNB may decode the received uplink transmission based, at least in part, on the assigned group of resources assigned to the UE and used for transmission. Additional orthogonalization techniques such as reduced TTI size can be used to reduce collisions among different users performing contention-based transmissions. Furthermore, when the eNB fails to successfully decode the uplink transmission, the eNB may identify the UE that sent the uplink transmission based on a detected reference signal and may transmit an uplink assignment to the identified UE.

Abstract translation: 某些方面涉及用于在RRC连接模式中的UE的等待时间减少的方法和装置。 在基于子帧内的UE组的基于竞争的上行链路接入期间，eNB至少部分地基于分配给UE并分配给用于传输的所分配的资源组来解码所接收的上行链路传输。 可以使用诸如减小的TTI大小的附加正交化技术来减少执行基于竞争的传输的不同用户之间的冲突。 此外，当eNB无法成功解码上行链路传输时，eNB可以基于检测到的参考信号来识别发送上行链路传输的UE，并且可以向所识别的UE发送上行链路分配。
