Abstract: Techniques are described to enable a user equipment (UE) to save power consumption and/or can enable the UE to acquire the channel state in time without reducing the UE's data transmission efficiency. An example technique includes determining, by the communication device, an operating mode based on a first signaling, and operating the communication device in the operating mode, where the operating mode includes any one of a normal mode, a first power saving mode, a second power saving mode, a third power saving mode, or a fourth power saving mode.

Abstract: The present invention relates to the field of wireless communications. Disclosed are a method and apparatus for sending a sounding reference signal. The method comprises: contending for a use permission of an unlicensed carrier according to listen-before-talk (LBT) or clear channel assessment (CCA) detection; and when the use permission of the unlicensed carrier is successfully contended, sending a sounding reference signal (SRS) on the unlicensed carrier. A method for transmitting an SRS and a PUSCH simultaneously or not simultaneously and a method for sending SRSs at part of uplink subframes are provided, and more SRS sending opportunities are provided. In downlink transmission, an SRS sequence is used as an occupied signal, thereby simplifying design of the occupied signal.

Abstract: Provided are a preamble transmission method and apparatus. The method comprises: a UE executing LBT on a first time frequency resource of an unlicensed carrier until a right to use the unlicensed carrier is acquired, wherein the LBT comprises LBT executed for transmitting a preamble; and after a right to use the access to the unlicensed carrier is acquired, the UE transmitting the preamble on a second time frequency resource located behind the first time frequency resource, wherein the second time frequency resource is a pre-configured PRACH time frequency resource at a fixed position, or a PRACH time frequency resource determined according to an LBT execution position. By means of the present disclosure, the problem in the relevant art of intra-cell interference caused by uplink data transmission over an unlicensed carrier is solved, and the uplink data transmission quality is improved.

Abstract: Presented are systems and methods for round trip time (RTT)-based positioning accuracy improvement. A first network node can communicate with a second network node to determine first measurement. The first measurement can correspond to a first round trip. The first network node can communicate with the second network node to determine second measurement corresponding to a second round trip. A first location of the first network node or a second location of the second network node can be determined based at least in part on the first measurement and the second measurement.
