    摘要: A technique for operating a wireless communications system that supports multi-user multiple-input multiple-output (MU-MIMO) communications between a base station and multiple mobile stations involves generating inter-cell interference information at the mobile stations and providing the inter-cell interference information to the base station. The base station uses the inter-cell interference information to calculate channel quality indicators (CQIs) and then makes scheduling decisions in response to the CQIs. Data is transmitted from the base station to the mobile stations according to the scheduling decisions.

    摘要: A method and device for indicating data re-transmission when area switching in LTE system, wherein the method comprises the following steps: S_eNB sends PDCP-SDU CN report to T_eNB in order to announce PDCP-SDU SN received, and T_eNB announces PDCP-SDU SN received by S_eNB to UE. Thereby, UE would not re-transmit PDCP-SDU corresponding to received SN, which avoids re-transmission of useless PDCP-SDU, and saves radio resources comparing with prior solutions.

    摘要: In a data packet router, a router fabric card for routing data packets is provided. The router fabric card comprises a plurality of ingress/egress ports, the ports connected through a switching facility for switching connection states of the port paths between individual ingress paths and individual egress paths on the fabric card, and a scheduling component for scheduling communication between ports on the fabric card. Data coming into ingress on the card is organized into individual data-packet trains, each individual train comprising data packets and inserted data denoting a starting point and an ending point of a train. The switching facility recognizes the start data and the end data of a train and switches port paths to a next-assigned connection state accordingly.

    摘要: Techniques for transmitting signals using time hopping or time and frequency hopping are described. In one design, a terminal selects different slots to use for transmission in multiple frames with time hopping. Each frame includes multiple slots, and each slot covers a particular time duration. The selected slots are at different time locations in the multiple frames. In another design, a terminal selects different resource units to use for transmission in multiple frames with time and frequency hopping. The selected resource units are at different time and frequency locations in the multiple frames. For both designs, the terminal sends a signal (e.g., a peer discovery signal) in the selected slots or resource units in the multiple frames. The terminal may detect for signals (e.g., peer discovery signals) from other terminals in slots not used for transmission by the terminal.
