Description

  The present application relates to the field of communications, and in particular to resource reconfiguration methods, base stations, and user equipment.

  When a user apparatus (User Equipment, abbreviated as UE) needs to perform uplink communication with a cell of a base station, it needs to acquire timing advance (TA) of that cell. The TA from a particular UE to a particular cell changes with changes in factors such as the location of the UE, and thus each time after obtaining the latest TA from the base station, the UE is notified by a Time Advance Timer (Time Advance Timer). Start or restart TAT). When the TAT times out, the UE considers that the previously acquired TA is no longer valid and thus the uplink resource configuration is released and all uplink transmissions except random access request are terminated, which is unnecessary Uplink interference is avoided. When the TAs from the UE to multiple cells are the same, the multiple cells belong to the same TA group. Cells belonging to the same TA group share the same TAT. The base station also maintains a timer in response to the TAT maintained by the UE. Each time after sending the latest TA to the UE, the base station also correspondingly starts or restarts the timer maintained by the base station, thus the base station is maintained by the base station By using the state of the timer, the state of the corresponding TAT maintained by the UE can be inferred.

  When the UE needs to transmit new uplink data to the base station, the UE transmits a scheduling request (Scheduling Request, SR) to a specific cell of the base station to request uplink resources. If the base station does not respond to the SR, the UE may transmit the SR repeatedly, but can not exceed the maximum number of repetitions. If the number of times the UE transmits an SR reaches the maximum number of repetitions, the UE considers that an SR failure has occurred. If the UE detects an SR failure, the UE releases uplink resource configuration and initiates a random access request to the base station.

  Physical Uplink Control Channel (PUCCH) resources are also needed for the UE to send SRs. In most cases, the base station configures PUCCH resources for transmitting SRs and transmits them in advance to the UE. However, since the PUCCH resources are relatively scarce, the base station can not pre-allocate PUCCH resources for transmitting SR to the UE depending on conditions such as uplink service of the UE.

  Uplink data arrives at the UE, but the UE detects that TAT has timed out, or detects that an SR failure has occurred, or that there is no PUCCH resource available for SR transmission After detection, the UE initiates a contention based random access process to the base station. In this process, the UE obtains updated TA and uplink grants (Uplink Grant, UL Grant, UL grant), and the uplink grant corresponds to the assigned uplink resource. The UE may transmit uplink data or control information such as Buffer Status Report (BSR for short) by using uplink resources. The base station may then send a reconfiguration message to the UE, the message including uplink resource configuration, the uplink resource configuration in particular: scheduling request (SR) configuration, sounding At least one of a reference signal configuration and a Channel Quality Indicator (CQI) reporting configuration. The UE sends SR, sounding and CQI to the base station according to the uplink resource configuration. In a new type of network deployment, UEs can communicate simultaneously with more than two base stations, one base station is referred to as the primary base station and the other base station is referred to as the secondary base station. The primary and secondary base stations may be connected.

  The PUCCH resource for the UE to send an SR to the secondary base station, according to the prior art, if the TAT of the secondary base station times out or if the SR failure of the UE occurs at the secondary base station or If it detects that it is not, the UE can start a contention based random access process only for the secondary base station, and then the secondary base station can send a reconfiguration message to the UE. However, prior art secondary base stations may not be equipped with a reconfiguration function, so the reconfiguration process may fail.
