    摘要: A transport block size (TBS) of a first uplink message (RACH Msg3) transmitted on a Physical Uplink Shared Channel (PUSCH) during a random access procedure in a User Equipment (UE) accessing a radio access network may be determined by receiving a pathloss threshold parameter. A downlink pathloss value indicative of radio link conditions between the UE and a base station (eNB) serving the UE is then determined. A smaller value of TBS is selected from a set of TBS values if the determined pathloss value is greater than an operating power level of the UE minus the pathloss threshold parameter. A larger value of TBS is selected if the pathloss value is less than the operating power level of the UE minus the pathloss threshold parameter and the TBS required to transmit the RACH Msg3 exceeds the smaller TBS value.

    摘要: A transmission of information from a secondary to a primary node occurs in a plurality of transmission instances which are logical time durations. A secondary node receives an allocation of periodic transmission instances for a scheduling request indicator (SRI) and an allocation if periodic transmission instances for a sounding reference signal (SRS). In a particular transmission instance allocated for the transmission of both SRS and SRI, the secondary node transmits the SRI without transmitting the SRS if the SRI indicates a pending scheduling request; otherwise, the secondary node transmits the SRS without transmitting the SRI.

    摘要: A cell within cellular network includes user equipment (UE) that transmits data to a base station (eNB). When a UE does not have data to transmit, it may enter a low power mode (DRX) having silent intervals during which the eNB does not expect to receive a transmission from the UE and the UE is not required to monitor DL control channels from the eNB. While in DRX mode, the UE may detect an event, such as data ready for transmission or a need to request a timing adjustment (TA) update. The UE transmits a scheduling request indicator (SRI) to the eNB in response to detection of the event, wherein the SRI carries information identifying the triggering event.

    摘要: Disclosed are a method and device for transmitting control information, to provide a control information sending manner based on a diversity transmission mode. The method for transmitting control information includes: determining the transmission of a plurality of enhanced control channel units (E-CCE) of an enhanced physical downlink control channel (E-PDCCH), each E-CCE containing the same number of enhanced resource unit groups (E-REGs), and a plurality of E-REGs contained in each E-CCE respectively belonging to a different frequency resource block (RB); and bearing each piece of downlink control information (DCI) to be transmitted over the E-PDCCH into at least one E-CCE for transmission. It is realized that each portion of one piece of DCI is respectively borne onto a plurality of frequency bands corresponding to the E-PDCCH for transmission, improving the stability and reliability of DCI transmission.
