摘要： 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.

摘要： Certain aspects of the present disclosure relate to methods and apparatus for reliable transmission of system information (SI). In some cases, a UE may send an indication to request SI in an on-demand manner. For example, a method for wireless communications by a UE may include determining system information (SI) desired by the UE is not currently being broadcast. The method for further include sending, in response to the determination, a first indication to request the SI, and sending a second indication to confirm reception of the requested SI or to indicate the UE has not received the requested SI after a time period.

摘要： A station configured to operate in a wireless network includes low-power protocol circuitry configured to operate according to a low-power protocol coupled to primary protocol circuitry configured to operate according to a first protocol. The low-power protocol circuitry includes a wake-up receiver configured to transition into a receive mode according to a medium access schedule. The wake-up receiver is also configured to receive synchronization signals from a wake-up transmitter of an access point in the wireless network. Each synchronization signal is received according to a slot-skipping transmit schedule of the wake-up transmitter. The low-power protocol circuitry also includes a low-power processor configured to synchronize a clock of the wake-up receiver to a clock of the wake-up transmitter based on at least one of the synchronization signals.

摘要： A method of operation of an electronic device includes receiving a discovery message from an access point using a wakeup receiver of the electronic device. The method further includes activating a modem of the electronic device in response to receiving the discovery message. Operation of the wakeup receiver is associated with a first power consumption that is less than a second power consumption associated with operation of the modem. The method further includes performing an association process with the access point using the modem after activating the modem.

摘要： Various aspects are provided for low-latency wireless local area networks. In a aspect, an access point (AP) may select, from a plurality of wireless stations associated with the AP, a wireless station for the AP to poll. Each of the plurality of wireless stations may be configured to transmit on a channel in response to being polled by the AP. The AP may transmit, at a time selected by the AP, a downlink frame including polling information to the wireless station on the channel, the polling information including a permitted duration for the wireless station to access the channel. The AP may monitor during the permitted duration for the AP to receive an uplink transmission from the wireless station on the channel, the uplink transmission from the wireless station being in response to the polling information received by the wireless station.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication that a cell associated with the base station does not support reduced capability UEs, wherein the UE is capable of operating in a first mode that is associated with reduced capability UEs and a second mode that is not associated with reduced capability UEs. The UE may communicate, in the second mode, with the base station to establish a connection with the cell based at least in part on at least one of: the UE supporting one or more capabilities associated with connecting with the cell, or no cells that support reduced capability UEs being available. Numerous other aspects are described.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine an average energy level radiated by the UE over a time period. The UE may determine whether the average energy level radiated by the UE over the time period exceeds a maximum permissible exposure (MPE) limit. The UE may transmit, to base station, a medium access control (MAC) control element (MAC-CE) that includes information related to a power management maximum power reduction (P-MPR) applied at the UE and/or an uplink duty cycle in effect at the UE based at least in part on the average energy level radiated by the UE over the time period exceeding the MPE limit. Numerous other aspects are provided.
