  • Patent number: 9788290
    Abstract: Embodiments of the present invention disclose a method, a device, and a system for sending, receiving, and determining timing reference information, and pertain to the communications field. The method for sending timing reference information includes: acquiring access time difference information reported by a mobile terminal; generating timing reference information according to the access time difference information, where the timing reference information includes identifier information of a timing reference cell; and sending the timing reference information to the mobile terminal. By technical means of determining one of two cells with different downlink channel timings as a timing reference cell and using the timing reference cell as a benchmark to feed back HARQ-ACK information, the present invention solves a timing problem encountered when a UE uses a same HS-DPCCH to jointly feed back two pieces of HARQ-ACK information of a serving cell and an assisting serving cell.

  • Patent number: 9693317
    Abstract: A configuration method for transmitting TPC command, a TPC command transmission method, and an apparatus. In the present invention, a radio network controller sends indication information to a terminal and a serving base station of the terminal to indicate a sending timeslot of an uplink TPC command of the terminal, so that sending timeslots of different TPC commands can be indicated for different terminals, and uplink TPC commands of multiple terminals are staggered in a timeslot. In this way, even if F-DPCHs of multiple terminals are configured with a same timeslot format, it can be avoided that locations of the uplink TPC commands are the same, and further a TPC peak-to-average ratio is lower than that in the prior art.

    Abstract: Embodiments of the present invention disclose a precoding control indication feedback method, a user equipment, and a base station. Channel capacity values corresponding to precoding matrices in a precoding matrix set are calculated. A sequence number of a precoding matrix corresponding to a maximum channel capacity value is used as a PCI to be used. The PCI to be used, a CQI indicating downlink channel quality, and ACK/NACK indicating a data decoding result are borne over an uplink HS-DPCCH. The same are fed back to a corresponding base station node to instruct the base station node to select a MIMO single-stream manner or a single-antenna manner to send data to be sent.

  • Publication number: 20150257140
    Abstract: The present invention provides a method, network side device and user equipment of variable bandwidth. The method includes: configuring a first type carrier and a second type carrier, wherein a chip rate of the first type carrier is 3.8 Mcps, a chip rate of the second type carrier is P*3.84 Mcps, and P is smaller than 1 and larger than 0; using the first type carrier and/or the second type carrier for communication. In this way, since the chip rate of the second type carrier is low and occupied bandwidth is small, the second type carrier may be suitable for non-standard bandwidth, thus utilization efficiency of bandwidth may be improved and waste of the bandwidth may be reduced.
