    摘要: Techniques for interference mitigation in a wireless communication system are disclosed. One example method includes receiving, at a first communication node, interference status information indicative of a remote interference between the first communication node and a second communication node and performing, by the first communication node, subsequent communications to the second communication node by implementing a backoff based on a granularity

    摘要: A wireless communication method is described for managing packet data convergence protocol (PDCP) service data unit (SDU). The method can include receiving, at a first protocol layer of a first communication device, a first service data unit (SDU) and a second service data unit (SDU) for a source from a second protocol layer for transmission to a second communication device. The method can also include starting a first timer with a first initial value for the first SDU, and starting a second timer with a second initial value for the second SDU. The second initial value can be different from the first initial value in response to determining that the second SDU is to be routed differently from the first SDU to the second communication device.

    摘要: A method and apparatus for plink carrier selection and uplink transmission in multi-carrier systems is disclosed. In one embodiment, a method performed by a wireless communication device, comprising: receiving a message containing first information of at least one first uplink transmission resource from a wireless communication node; based on the first information, determining at least one power headroom (PH) value for the at least one first uplink transmission resource; and reporting second information of the at least one first uplink transmission resource to the wireless communication node.

    摘要: 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.

    摘要: 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.

    摘要: An information processing method, a corresponding base station and terminal are disclosed. The method includes presetting a subframe structure comprising at least a first time slot and a second time slot, herein the first time slot is used for transmission of a downlink signal; or is idle; or is switched to reception of an uplink signal and schedules transmission of the uplink signal or does not schedule transmission of the uplink signal; or is switched to reception of a signal for only performing reception and measurement of other signals but does not schedule transmission of the uplink signal; and the second time slot is used for reception of an uplink signal and schedules transmission of the uplink signal; or is idle, or is switched to reception of a signal for only performing measurement but does not schedule the uplink signal.
