Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a limit on a number of resource blocks (RBs) permitted to be used for a vehicle-to-everything (V2X) transmission by the UE; may determine, based at least in part on the limit, one or more parameters for the V2X transmission, wherein the one or more parameters include at least one of a modulation and coding scheme (MCS) for the V2X transmission, a number of transport blocks (TBs) for the V2X transmission, a number of RBs per TB for the V2X transmission, or a retransmission configuration for the V2X transmission; and may transmit the V2X transmission based at least in part on the one or more parameters. Numerous other aspects are provided.

Abstract: A method, apparatus, and computer-readable medium at a transmitting user equipment (UE) in a distributed cellular vehicle-to-everything environment are disclosed to determine a schedule for transmissions on subchannels of multiple frequencies based on a set of UE-specific, dynamic, and performance related metrics or criteria. The metrics may include an estimated number of users on a subchannel, a best-bandwidth fit, channel loading conditions, transmission range, and quality requirements of an application, among others. Such a schedule for transmissions on subchannels of multiple frequencies may result in either an improved capacity utilization, an improved communication quality, or both.

Abstract: A user equipment (UE) determines a first transmit power parameter for a primary carrier and a secondary carrier of a multi-carrier uplink, based on a first data power allocated for a first data type to be transmitted on the multi-carrier uplink. The UE determines a first maximum enhanced uplink transport format combination indicator (E-TFCI) for the primary carrier and the secondary carrier based on the first transmit power parameter. If the primary carrier or the secondary carrier has data of a second data type for transmission, the UE determines a second data power allocated for the first data type utilizing the first maximum E-TFCI as a reference E-TFCI. If a difference in value between the first data power and the second data power is less than a threshold value, the UE utilizes the first transmit power parameter for transmitting data on the primary carrier and the secondary carrier.

Abstract translation: 用户设备（UE）基于为在多载波上行链路上发送的第一数据类型分配的第一数据功率，确定主载波和多载波上行链路的辅载波的第一发射功率参数。 UE基于第一发射功率参数确定主载波和辅载波的第一最大增强上行链路传输格式组合指示符（E-TFCI）。 如果主载波或辅载波具有用于传输的第二数据类型的数据，则UE使用第一最大E-TFCI作为参考E-TFCI来确定为第一数据类型分配的第二数据功率。 如果第一数据功率和第二数据功率之间的差值小于阈值，则UE利用第一发射功率参数在主载波和辅载波上传输数据。
