Description

  The present invention relates to the field of communication technology, and in particular, to a communication method, apparatus, and system.

  There are two different types of network nodes in a network deployment scenario. That is, an evolved base station (Evolved NodeB, eNB) and a small cell node (Small Cell Node, SCN). The eNB and the SCN may individually control one or a plurality of cells, and may use different frequencies from the eNB cell and the SCN cell. The eNB cell covers a large area and may be referred to as a macro cell. SCN cells cover a small area and may be referred to as small cells.

In the prior art, one of the following situations can occur:
The time alignment timer (Time Alignment Timer, TAT) set for the macro cell in the user equipment (User Equipment , UE) expires, and the UE needs to transmit uplink data or a signal to the eNB.
There is no resource for transmitting a scheduling request (SR) in a macro cell in the UE, and the UE needs to transmit uplink data or a signal to the eNB.
The UE fails to transmit a dynamic scheduling request (Dynamic Scheduling Request (DSR)) in a macro cell, and the failure of the DSR indicates that the number of SRs continuously transmitted by the UE exceeds the preset maximum number. Due to that.

  When any one of the above three situations occurs, the UE must first initiate a contention-based random access procedure to the eNB, and only after this procedure is complete, the UE sends uplink data or signals to the eNB. The eNB may transmit downlink data or signals to the UE in response to its uplink data or signals.

  The following clearly and completely describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. It will be appreciated that the embodiments described are not all embodiments of the invention, but only a part thereof. All other embodiments that can be obtained by a person skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

  Referring to FIG. 1, a communication method according to an embodiment of the present invention includes the following.

  101: The user equipment sends a request message to the micronetwork node, thereby enabling the micronetwork node to send an indication message to the macro network node.

  The request message in the embodiment of the present invention may be an access request message, a scheduling request message, a connection request message, a request message for transmitting new data or a signal, or a radio resource control (RRC) message, It can also be a physical signal or a control information element.

102: The user equipment receives the uplink resource ( UG ) transmitted by the macro network node in response to the instruction message.

103: The user equipment transmits an uplink signal or uplink data to the macro network node according to the uplink resource ( UG ) .

In an embodiment of the present invention, the UE sends a request message to the micronetwork node, thereby enabling the micronetwork node to send an indication message to the macro network node. Further, the UE receives an uplink resource ( UG ) transmitted by the macro network node in response to the instruction message, and transmits an uplink signal or uplink data to the macro network node in accordance with the uplink resource ( UG ) . Compared to the prior art in which the micronetwork node does not participate and the UE performs access using contention-based random access procedures directly, the solution provided by the embodiments of the present invention allows the UE to network more quickly. Access delay, and thus UE access delay can be reduced.

  When implementing the present invention, none of the user equipment, the macro network node, and the micro network node controls the transmission of uplink data or uplink signals by the UE. As long as the user initiates an access request, after the macro network node receives an indication from the micro network node, the macro network node allocates uplink resources to the user equipment.

Optionally, based on the embodiment corresponding to FIG. 1, in the first optional embodiment of the communication method according to the embodiment of the present invention, the uplink resource ( UG ) transmitted by the macro network node in response to the indication message The step of receiving
Receiving a first timing advance ( TA ) and uplink resource ( UG ) using a non-contention based random access procedure.

Correspondingly, the step of transmitting an uplink signal or uplink data to the macro network node according to the uplink resource ( UG ) is:
In response to the first timing advance ( TA ) and the uplink resource ( UG ) , the method includes transmitting an uplink signal or uplink data to the macro network node.

In an embodiment of the present invention, the non-contention based random access procedure is defined in detail in the 3rd Generation Partnership Project (3GPP) protocol TS 36.321, in particular, the macro network node is non-conflicting. A base random access command to the UE, the UE responds to a non-contention based random access command by sending a random access request to the macro network node, and the macro network node sends a random access response to the UE. The random access response includes allocated uplink channel resources ( UG ) and timing advance (Time Advance, TA). Thereby, UE can acquire uplink transmission time according to TA, and transmits an uplink signal or uplink data in uplink transmission time using UG.

Optionally, based on the embodiment corresponding to FIG. 1, in the second optional embodiment of the communication method according to the embodiment of the present invention, the uplink resource ( UG ) transmitted by the macro network node in response to the indication message The step of receiving
Receiving an uplink resource ( UG ) transmitted by the macro network node over a physical downlink control channel ( PDCCH ) .

Correspondingly, the method is
The method further includes reading an existing second timing advance ( TA ) .

Depending on the uplink resource ( UG ) , sending the uplink signal or uplink data to the macro network node
In response to the second timing advance ( TA ) and the uplink resource ( UG ) , the method includes transmitting an uplink signal or uplink data to the macro network node.

  In the embodiment of the present invention, when the TA exists in the UE, the UE does not need to acquire the TA from the macro network node. Thus, even without using a non-contention based random access procedure, the macro network node can still assign a UG to the UE. For example, the macro network node directly transmits the UG allocated to the UE to the UE through a physical downlink control channel (Physical Downlink Control Channel, PDCCH).

Optionally, in the third optional embodiment of the communication method according to the embodiment of the present invention based on the embodiment corresponding to FIG. 1 and the first or second optional embodiment corresponding to FIG. And the indication message both carry uplink signal or uplink data size information, and the uplink signal or uplink data size information is used by the macro network node to determine the uplink resource ( UG ). The

  In the embodiment of the present invention, the UE may add the size of the uplink signal or uplink data transmitted in the above-described embodiment to the transmitted request message. Thereby, the macro network node can determine the size of the UG according to the size of the uplink signal or the uplink data. Therefore, compared to the UG randomly assigned in the above-described embodiment, the UG assigned in the embodiment of the present invention accurately matches the uplink signal or uplink data to be transmitted. As a result, it is avoided that the allocated uplink resources are insufficient to transmit uplink signals or uplink data, or that excessive UGs are allocated and UGs are not wasted.

Optionally, in the fourth optional embodiment of the communication method according to the embodiment of the present invention, based on the embodiment corresponding to FIG. 1 and the first to third optional embodiments corresponding to FIG. Before sending the request message to the micronetwork node,
Further comprising determining first control information of an uplink signal or uplink data;
Both the request message and the instruction message carry first control information, which is used by the macro network node to perform user equipment access control.

  The emergency instruction information indicates whether data or a signal that needs to be transmitted by the UE is urgent.

  Specifically, the emergency indication can be represented by a bit. A bit of 1 indicates that the data or signal is urgent and a bit of 0 indicates that the data or signal is not urgent. The reverse is also true.

  Service type indicates the type of service initiated by the UE. Specifically, this information is any one of an emergency call, a high priority service, a delay insensitive service, and the like.

  Data / signal information indicates whether data or signals are transmitted by the UE.

  Quality of Service (QoS) information includes the QoS parameters of the service to which the uplink signal or uplink data transmitted by the UE belongs, in particular, QoS Class Identifier (QCI), assignment and Retention priority (Allocation and Retention Priority, ARP) and the like may be included.

Here, the access control rule is preset by the system and stored in the macro network node.

S220: The macro network node initiates a non-contention based random access procedure, thereby enabling the UE to obtain uplink resources ( UG ) and TA allocated by the macro network node.

For example, when the second control information includes emergency instruction information and the value of the emergency instruction information is “emergency”, the third control information determined by the user equipment is an emergency instruction of an uplink signal or uplink data. Information. If the value of the emergency indication information in the uplink signal or uplink data is also “emergency”, the user equipment may send a request message. As another example, if the second control information includes service type information and data / signal information, the value of service type information is “emergency call”, and the value of data / signal information is “signal”, the user The third control information determined by the equipment is service type information and data / signal information of the uplink signal or uplink data. If the value of the service type information of the uplink signal or uplink data is “emergency call” or the value of the data / signal information of the uplink signal or uplink data is “signal”, the user equipment shall send a request message Can be sent.
