Abstract: Additional requirements for spectrum emissions may be matched with regional requirements, and an additional maximum power reduction (A-MPR) for a user equipment (UE) may be based on an actual antenna gain of the UE. For example, a UE may be located in a particular region and be required to meet regional requirements for wireless communications. In such cases, the UE may receive network signaling from a base station, and identify an antenna gain for its antenna. The UE may then identify a set of emission requirements based on the identified antenna gain and the network signaling. Additionally, the UE may identify an A-MPR based on the set of emission requirements and the antenna gain and may adjust a maximum output power in accordance with the identified A-MPR. In some examples, an output power threshold may be derived using a difference between a regional requirement and the UE's antenna gain.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) that is configured to transmit a message to a neighboring UE via multiple formats, identify a service parameter indicative of a format to be used for the message. The UE may convey information indicating the service parameter from a first layer of the UE to a second layer of the UE, wherein the first layer is an upper layer with respect to the second layer. The UE may generate, by the second layer and based at least in part on the information, the message in the format for communicating with the neighboring UE. Other aspects, embodiments, and features are claimed and described.

Abstract: Methods, systems, and devices for wireless communication are described. A transmitting device may identify resource blocks (RBs) used to transmit data in a data transmission. The transmitting device may determine a frequency width of a data channel in a frequency domain that is used to transmit the data based at least in part on the identified RBs. The transmitting device may dynamically determine an allocation of RBs used to transmit control information in a control channel. The allocation of RBs may be based on the frequency width of the data channel and may cause a frequency width of the control channel to match the frequency width of the data channel in the frequency domain. The transmitting device may transmit the control information in the control channel to indicate a location of the data channel.

Abstract: Methods, systems, and devices for wireless communication are described. Contention procedures may include a shared radio frequency (RF) spectrum region to access resources in another shared RF spectrum region. For example, a wireless device may operate in a synchronous system and identify a set of target resources for a data transmission. The wireless device may contend for the target resources by performing a procedure, such as a listen-before-talk (LBT) procedure, in a first shared RF spectrum region that is smaller than, and overlaps in frequency with, a second shared RF spectrum region that includes the target resources. Resources used for the LBT procedure may be included in a different time period than the target resources, where LBT resources may correspond to target resources in different time periods. The target resources may also include multiple sub-channels, and LBT resources may be mapped to one or more of the sub-channels.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided that enable UEs to conserve power while involved in ProSe communication. The apparatus transmits discovery class information for ProSe communication to an A-UE and to an M-UE. The discovery class information may be transmitted from a PF in response to discovery requests. Discovery class rules may be sent from the PF as a part of service authorization. The discovery class information may be transmitted from a ProSe application server as application layer signaling. The A-UE and M-UE may use the discovery class information to select a pool of ProSe resources according to the discovery class information for transmission or monitoring of ProSe communication. The M-UE may use the information to reduce the number of resource pools of resources that are monitored for ProSe communication.

Abstract: In one aspect of this disclosure, control information and data are carried in the same subframe in order to reduce control overhead. A method, an apparatus, and a computer-readable medium for wireless communication are provided. The apparatus may be a first UE. The first UE determines a data block to be transmitted to a second UE. The first UE determines a first resource in a subframe for carrying the data block and determines a second resource in the subframe for carrying control information associated with transmitting the data block. The first UE transmits the data block and the control information to the second UE in a device-to-device communication channel on the determined first and second resources, respectively.

Abstract: Improved methods, systems, or apparatuses for UE equipment testing for D2D enabled UEs may include determining performance metrics based on one or more of received transport blocks (TBs) or received service data units (SDUs) from the received one or more data channels on a per channel basis, and reporting the determined performance metric(s) on a per channel basis. In some examples, the performance metrics may include a count of a number of TBs or SDUs successfully received at a channel.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The apparatus may transmit a message in a first subset of a set of resources. The message may include a position of the apparatus and a resource ID indicating at least one symbol in a second subset of the set of resources for transmitting a sequence. The apparatus may transmit the sequence in the at least one symbol in the second subset of the set of resources identified by the resource ID, receive at least one other sequence, adjust a transmission timing based on the received at least one other sequence, and transmit, based on the adjusted transmission timing, the sequence in one or more symbols in a third subset of the set of resources.

Abstract: A transmitting UE may in a device-to-device (D2D) communication may identify a demodulation reference signal (DMRS) sequence for a D2D transmission based at least in part on a subset of bits of a sidelink control information (SCI) transmission. The subset of bits of the SCI transmission may be selected such that the bits have sufficient variability to reduce the likelihood that multiple UEs may use the same DMRS sequence. The subset of bits of the SCI transmission may be all or a portion of a cyclic redundancy check (CRC) for the SCI.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives information from a serving base station and at least one neighboring base station. The information indicates a time allocation of discovery resources allocated by each of the serving base station and the at least one neighboring base station for performing direct discovery. The apparatus further determines a subframe timing of the serving base station and the at least one neighboring base station, and performs direct discovery using the time allocation of the discovery resources allocated by each of the serving base station and the at least one neighboring base station based on a determined subframe timing of the serving base station or a neighboring base station corresponding to the discovery resources.
