- the eNB cannot determine that the UE is in the UE. Which component carriers are receiving data, or which component carriers are being monitored, that is, the eNB does not know the exact component carrier that should send the random access response message. In order for the UE to receive the data, the eNB needs to send random connections on all component carriers. In response message, As a result, the downlink resources are wasted; at the same time, the UE needs to listen to all component carriers, which increases the power consumption of the UE. Summary of the invention
- the random access response message is sent on one of the determined component carriers or one of the component carriers.
- the embodiment of the present invention further provides a random access method, including:
- an evolved base station including:
- a determining unit configured to determine one or more component carriers that the user equipment needs to monitor in a discontinuous reception state
- FIG. 7 is a schematic structural diagram of a terminal device according to an embodiment of the present invention.
- Step 103 After receiving the dedicated random access preamble (Preamble) sent by the UE, Sending a random access response message on one of the determined component carriers or one of the plurality of component carriers.
- Preamble dedicated random access preamble
- Step 202 Listen to one or more component carriers that need to be monitored in the notification.
- Step 203 After sending the dedicated random access Preamble to the eNB, receiving a random access response message sent by the eNB on one of the component carriers or one of the component carriers.
- an eNB is a serving eNB of a UE, and the method includes the following:
- Step 300 The eNB determines a component carrier that the user equipment UE needs to listen to at least in the DRX state. Specifically, the eNB may determine, according to the component carrier that the UE can support and/or the current ongoing service requirement, the component carrier that the UE needs to listen at least.
- the UE After transmitting the dedicated random access Preamble, the UE receives the random access response message on the component carrier determined by the eNB, that is, the DRX command or one or more component carriers indicated in the dedicated indication message.
- Step 306 After receiving the dedicated random access Preamble, the eNB sends a random access response message on at least one component carrier of the one or more component carriers that are notified.
- the eNB determines, for the UE, a plurality of component carriers that need to be monitored in the DRX state, the eNB sends a random random transmission on the one of the determined component carriers after receiving the dedicated random access Preamble sent by the UE.
- the access response message is sent to the UE.
- the random access response message may also be sent to the UE on multiple determined component carriers.
- step 301 if the eNB informs the UE of one or more component carriers that need to be monitored when entering the DRX state through a dedicated indication message, in this step 306, after transmitting the dedicated random access Preamble to the eNB, the eNB may pass A random access response message is received on the component carrier indicated in the dedicated message.
- the specific implementation process is similar, and will not be described here.
- the evolved base station eNB negotiates with the UE the component carriers that should be monitored during the active state before the UE enters the discontinuous reception DRX state, and determines one or more components that the UE needs to listen at least when the uplink is out of synchronization according to the result of the negotiation.
- Carrier and notifying the UE of at least one component carrier that needs to be monitored;
- Step 402 After receiving the DRX command, the UE determines to listen to the monitoring carrier pre-negotiated with the eNB in the step 400 in the DRX state; when the wake-up time arrives or in the "on duration" phase, the UE monitors the PDCCH of the determined component carrier. channel.
- the UE which is the component carrier that should be monitored when it is in the on duration phase in the subsequent DRX process.
- the UE listens to the component carrier indicated in the system message in the on duration phase according to the indication of the system message.
- the component carrier that should be monitored during the on duration phase specifically, the UE should listen to the group used before entering the DRX state in the subsequent on duration phase.
- the engine component carrier may be a cell-specific engine component carrier or a UE-specific engine component carrier.
- the so-called cell-specific engine component carrier refers to one or more control capabilities of all component carriers of the cell that are superior to other component carriers.
- the component carrier is a UE-specific component carrier, which means that the control capability of the component carrier used by the UE is better than one or more component carriers of other component carriers.
- n is a positive integer and is set by the eNB.
- Step 404 The eNB allocates a PDCCH and a dedicated random access preamble to the UE to instruct the UE to perform a random access procedure to obtain uplink synchronization.
- the eNB allocates a dedicated random access Preamble to the UE.
- FIG. 5 is a flowchart of a method for random access according to Embodiment 3 of the present invention. the method includes:
- Step 503 When the downlink data of the UE arrives, it is determined whether the UE is in an uplink synchronization state, and if yes, the downlink data is sent to the UE (not shown); otherwise, step 504 is performed;
- Step 504 The eNB determines a component carrier that the UE needs to monitor at least when the uplink is out of synchronization, and the component carrier is used to send a random access response message to the UE.
- the eNB may be configured according to a component carrier and/or current that the UE can support.
- the ongoing business requirements determine the component carriers that the UE needs to listen to at least.
- the eNB may also allocate different dedicated random access Preambles on the PDCCHs of different component carriers, as specifically, in steps 504' to (not shown): Step 504': The eNBs are different. Assigning different dedicated random access Preamble to the UE on the PDCCH of the component carrier

Abstract
L'invention porte sur un procédé d'accès aléatoire, sur un nœud B évolué et sur un équipement terminal. Le procédé comprend les étapes suivantes consistant à : déterminer une ou plusieurs porteuses de composition devant être détectées par l'équipement utilisateur (UE) dans l'état de réception discontinue (DRX), informer l'équipement utilisateur de la ou des porteuses de composition, et transmettre le message de réponse d'accès aléatoire sur l'une des porteuses de composition déterminées après réception du préambule d'accès aléatoire dédié envoyé par l'UE. Par conséquent, le nœud B évolué pourrait déterminer la porteuse de liaison descendante détectée par l'UE lorsque l'UE est dans le processus d'accès aléatoire non compétitif de l'état DRX, le taux d'utilisation de la ressource de liaison descendante est augmenté et la consommation d'électricité de l'UE est réduite.
