Patent Description:
In a Long Term Evolution (LTE) system, uplink and downlink transmission of UE is generally implemented based on scheduling of a base station. The UE, when being in an active state, needs to detect whether there is scheduling signaling for it or not on each transmission unit such as each subframe. The UE may search a position where the downlink scheduling signaling may appear for a corresponding Downlink Control Information (DCI) format according to a transmission mode supported by the UE, the detection performance of scheduling signaling and the detection complexity may be influenced by the number of detections supported by the UE on each transmission unit. When the number of detections supported by the UE is higher, the detection performance of scheduling signaling can be higher but the detection complexity and power consumption of the UE may be increased accordingly.

In a related art, in researches and discussions about 5th Generation (<NUM>) projects, since a bandwidth of a working carrier is wide, multiple control regions configured to detect control information may be configured for UE; and moreover, the UE may support different scheduling types. These factors may cause great increase of detection complexity of the UE. In the related art, detection of a control channel configured for UE by a base station may be beyond a detection capability of the UE, and consequently, the UE cannot successfully detect whether there is scheduling signaling for itself or not; or the detection efficiency of the UE may be reduced by excessively high detection complexity of the UE.

The method for implementing signaling detection may be applied to UE. As shown in <FIG>, the method for implementing signaling detection includes the following Steps <NUM>-<NUM>.

In Step <NUM>, information for identifying a detection capability is determined based on a signaling detection capability supported by the UE.

The detection capability supported by the UE is measured the number of detections.

The information for identifying a detection capability is a random access preamble. A mapping relationship between a random access preamble and a signaling detection capability may be established, and then the random access preamble may be used as the information for identifying a detection capability identifying the signaling detection capability. For example, if sequence <NUM> corresponds to a first signaling detection capability and sequence <NUM> corresponds to a second signaling detection capability, then information for identifying a detection capability of the first signaling detection capability is the sequence <NUM>, and information for identifying a detection capability of the second signaling detection capability is the sequence <NUM>.

In an embodiment, the information for identifying a detection capability may be dedicated information configured to identify the signaling detection capability.

In an embodiment, the information for identifying a detection capability may be obtained by redesigning the existing communication parameter. For example, when the random access preamble is designed, an information field configured to identify the signaling detection capability may be added to a preset position of the random access preamble to obtain a set of new random access preambles, and the set of new random access preambles may be used for random access and for reporting of the information detection capability.

In an exemplary scenario, as shown in <FIG>, exemplary descriptions are made with the condition that a mobile network is a <NUM> network as an example (the technical solution of the present disclosure is also applied to another communication system and is not limited to the <NUM> network). The scenario shown in <FIG> includes a base station <NUM> and UE <NUM>. The UE <NUM> reports information for identifying a detection capability configured to identify a signaling detection capability of the UE.

As shown in <FIG>, the following steps are included.

In Step <NUM>, information for identifying a detection capability is determined based on a signaling detection capability supported by UE.

When the signaling information for identifying a detection capability is reported through a first message in a random access request, the information for identifying a detection capability is a random access preamble.

In an embodiment, a system may predetermine a corresponding relationship between a random access preamble and a signaling detection capability, and the UE may determine the random access preamble corresponding to the supported signaling detection capability based on the corresponding relationship. For example, if sequence <NUM> corresponds to a first signaling detection capability, then, when the UE determines that the signaling detection capability supported by the UE is the first signaling detection capability, the sequence <NUM> may be selected as the random access preamble during random access.

In an embodiment, the system may divide a random access preamble sequence into N sets based on the number N of signaling detection capabilities, one signaling detection capability corresponding to one set, and the UE may select a random access preamble from the corresponding set based on the signaling detection capability supported by the UE to initiate an initial access process.

In an embodiment, the system may add an information field representing the signaling detection capability of the UE to a fixed position in the random access preamble sequence when the random access preamble is designed. An information value of the information field corresponds to a signaling detection capability. For example, when an information value of the information field representing the signaling detection capability is <NUM>, the information value may correspond to a first signaling detection capability, and when the supported signaling detection capability is the first signaling detection capability, the UE may select a random access preamble where a value of an information field representing the signaling detection capability is <NUM> to initiate the initial access process. In an embodiment, a length of the information field representing the signaling detection capability of the UE may be predefined based on the number of signaling detection capabilities supported by the UE. For example, if the number of the signaling detection capabilities supported by the UE is <NUM>, the length of the information field may be set to be <NUM> bits.

In Step <NUM>, the information for identifying a detection capability is reported through a first message in a random access procedure.

In an embodiment, the first message may be sent on a time-frequency resource for the first message in the random access procedure, the message containing the information for identifying a detection capability.
