Abstract: Certain aspects of the present disclosure provide techniques and apparatus for managing transmit power in a television white space (TVWS) network. One example method generally includes transmitting a sequence of request-to-send (RTS) messages at different transmit power levels to an apparatus and determining if a clear-to-send (CTS) message was received in response to at least one of the RTS messages corresponding to a particular one of the transmit power levels. Another example method generally includes receiving, at a first apparatus from a second apparatus, a packet that cannot be decoded by the first apparatus; determining at least one of a time or a duration corresponding to the packet; transmitting a query with an indication of the at least one of the time or the duration; and receiving a message from the second apparatus in response to the query, the message identifying the second apparatus as a source of the packet.

Abstract: In order to improve efficiency in releasing a connection with a user equipment, a method, apparatus, and computer-readable medium are presented herein. A RAN receives release assistance information from a user equipment or a User Plane Function (UPF) involved in an active session with the user equipment. The release assistance information may be received over a control plane or over a user plane. The release assistance information may be received from the user equipment or the UPF over the user plane or as Radio Resource Control (RRC) signaling. The release assistance information may be received from an application function via the UPF. The RAN determines to release the user equipment based on the release assistance information.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for wireless communication over a neighbor awareness networking (NAN) data link (NDL). In some aspects, an apparatus may be configured to determine frequency band information for communicating over a NDL associated with a NAN service. In some other aspects, the apparatus may be configured to provide the determined frequency band information for transmission to a subscriber of the NAN service for setting up the NDL.

Abstract: Aspects of the disclosure relate to a method of operating a user equipment for wireless communication with a network. In some aspects, the UE establishes a connection to a network and obtains a control plane message from the network. The control plane message may include one or more types of policy information if a size of the one or more types of policy information is less than or equal to a maximum payload size of the control plane message, or information indicating at least a network location from where the one or more types of policy information may be obtained by the UE over a user plane if the size of the one or more types of policy information is greater than the maximum payload size of the control plane message, or a combination thereof. Other aspects, embodiments, and features are also claimed and described.

Abstract: A leader-follower protocol is provided for wireless communication in a BAN. A connection is established between a leader of the BAN and at least one follower in the BAN. The follower refrains from transmitting until a transmission is received from the leader. The transmission from the leader triggers a transmission opportunity at the follower for a window of time. Once the follower receives a transmission from the leader, the follower may then transmit a second transmission to the leader within the window of time. The transmission from the leader that triggers the transmission opportunity for the follower may be a data transmission, a poll transmission, an ACK a sleep mode message, etc. After transmitting a transmission to the a follower, the leader refrains from transmitting for the window of time in order to accommodate the transmission opportunity for the at least one follower.

Abstract: Techniques are described using network slice information to negotiate and select network services by determining a set of desired required network provided functionalities; identifying a set of network slices providing one or more of the functionalities in the set of required functionalities; and communicating, to a network, a slice identifier for each slice in the set of the identified network slices.

Abstract: Techniques and apparatus for controlling the transmit power of an uplink (UL) signal from a user terminal in a wireless communications system in an effort to achieve some target characteristic, such as a target carrier-to-interference (C/I) ratio, at an access point (AP) are provided. In this manner, such a user terminal may help avoid or compensate for imbalances in received radio frequency (RF) power between UL signals received from multiple user terminals by the AP. For example, the transmit power at each user terminal may be controlled in an effort to achieve a target post-processing C/I ratio of 28 dB per spatial stream in an effort to reduce large power imbalances and optimize throughput per user terminal. The user terminal and the AP may compose part of a multiple-input multiple-output (MIMO) communication system utilizing spatial-division multiple access (SDMA) techniques.
