    Abstract: Techniques for performing open-loop rate control in a TDD communication system are described. The channel quality of a first link is estimated based on a transmission received via the first link. The channel quality of a second link is estimated based on the estimated channel quality of the first link and an asymmetric parameter. At least one rate for a data transmission via the second link is selected based on the estimated channel quality of the second link. The estimated channel quality for each link may be given by a set of SNR estimates for a set of transmission channels on that link. The asymmetric parameter may be determined based on (1) the capabilities (e.g., transmit power, receiver noise figure, and number of antennas) of the transmitting and receiving stations or (2) received SNRs for the first and second links.

    Abstract: A method of selecting a transmission mode for data transmission in a wireless communication system is described. The method comprising determining the age of channel information available for use to transmit data via a wireless channel, comparing the age of the channel information against a threshold, and selecting a steered mode when the age of the channel information is less than or equal to the threshold and selecting an unsteered mode when the age of the channel information is greater than the threshold, and processing data in accordance with the selected transmission mode wherein the channel information is used for processing when the steered mode is selected and the channel information is not used for processing when the unsteered mode is selected. Further, a corresponding apparatus is described.

    Abstract: A method and apparatus provide for configuring WLAN measurements for unlicensed spectrum communications. The method and apparatus include receiving, at a network entity, a UE capability message and a reporting message from a UE, determining whether the UE is capable of communicating over the unlicensed spectrum and supports WLAN measurements based on the UE capability message and the reporting message, and transmitting, to the UE, a measurement configuration message including a measurement configuration identifier in accordance with the determination that the UE is capable of communicating over the unlicensed spectrum and supports WLAN measurements. The method and apparatus further include receiving, at a UE, a measurement configuration message and a measurement purpose message from a network entity, determining a measurement configuration of the UE based on the measurement purpose message, and performing one or more measurements for the one or more WLAN access points.

    Abstract: Aspects directed towards Quality of Service (QoS) flow remapping are disclosed. In an example, upon detecting a mapping reconfiguration of a first QoS flow from a first data radio bearer (DRB) to another DRB, a Service Data Adaptation Protocol (SDAP) control protocol data unit (PDU) is generated indicating that a final SDAP data PDU associated with the first QoS flow has been transmitted on the first DRB. The SDAP control PDU is then transmitted via the first DRB. In another example, upon detecting a mapping reconfiguration of a first QoS flow from a first DRB to another DRB, an end marker parameter is set in an SDAP header of a first SDAP data PDU received from an upper layer after the mapping reconfiguration indicating that the first SDAP data PDU is a final SDAP data PDU associated with the first QoS flow transmitted on the first DRB.

    Abstract: TECHNIQUES FOR IMPROVING POWER SAVING BY STATIONS IN WIRELESS NETWORKS ARE DESCRIBED. IN AN ASPECT, A SOURCE STATION SENDS A FRAME (300) WITH A BUFFER STATUS FOR A RECIPIENT STATION DURING AN AWAKE TIME FOR BOTH STATIONS AND SENDS ONE OR MORE DATA FRAMES TO THE RECIPIENT STATION AS INDICATED BY THE BUFFER STATUS. THE RECIPIENT STATION KNOWS HOW MANY DATA FRAMES TO EXPECT BASED ON THE BUFFER STATUS AND CAN GO TO SLEEP AFTER RECEIVING THE EXPECTED NUMBER OF DATA FRAMES. IN ANOTHER ASPECT, A SOURCE STATION RECEIVES A FRAME WITH INFORMATION ON TRANSMISSION OPPORTUNITY (TXOP) BURSTING RECEIVE CAPABILITY OF A RECIPIENT STATION OPERATING IN A. POWER SAVE MODE. THE SOURCE STATION PERFORMS CHANNEL ACCESS AT THE START OF A TXOP AND SENDS MULTIPLE DATA FRAMES IN THE TXOP TO THE RECIPIENT STATION BASED ON THE TXOP BURSTING RECEIVE CAPABILITY OF THE RECIPIENT STATION.
