Method and device for acquiring user equipment duplex specification information

The present invention relates to the field of mobile communications, and more particularly to a method and device for acquiring a duplex specification message of a user equipment (User Equipment, UE).

For the cellular mobile communication system, the duplex mode is the multiplex mode of uplink and downlink connections; for mobile communication devices (base station or UE), the duplex mode is the multiplex mode of transmitting and receiving links. Time Division Duplex (TDD) and Frequency Division Duplex (FDD) are two basic duplex modes in wireless communication transmission. They are simultaneously supported in Long Term Evolution (LTE) systems. TDD specifications and FDD specifications. Under the TDD specification, the uplink and downlink links use different time intervals for uplink and downlink signal transmission; while in the FDD specification, the uplink and downlink links use different working frequency bands for uplink and downlink signal transmission. Please refer to Figure 1 (a), Figure 1 (b), Figure 1 (c) and Figure 2, Figure 1 (a), Figure 1 (b), Figure 1 (c) is the schematic diagram of the duplex mode, Figure 2 A schematic diagram of the time-frequency relationship in the basic duplex mode.

For the basic duplex mode adopted by the cellular system, in the TDD specification, the uplink and downlink links use the same working frequency band, and the uplink and downlink signals are transmitted at different time intervals, and there is a guard interval between the uplink and the downlink (Guard). Period, GP); Under the FDD specification, the uplink and downlink links use different working frequency bands, and the uplink and downlink signals can be transmitted on different frequency carriers at the same time. There is a guard bandwidth between the uplink and the downlink. .

In the basic TDD cellular mobile communication system, mobile communication devices (including base stations or UEs) also work in TDD mode, and the device needs to have a transceiver switch; in the basic FDD cellular mobile communication system, mobile Communication equipment (including base stations or UEs) also works in FDD mode, and transceiver duplex filters are required in the equipment.

In the LTE system, the FDD specification and the TDD specification adopt different time frame structures, as described below: Please refer to FIG. 3 and FIG. 4, FIG. 3 is a schematic diagram of the time frame structure of the LTE FDD system, as shown in FIG. 3, in the LTE FDD. In the time frame structure of the system, a wireless time frame has a length of 10 ms and contains 10 sub-time frames. Each sub-time frame has 2 time slots (Time Slot, Ts), each of which is 0.5 ms, and Ts is a sampling interval.

The time frame structure of the LTE TDD system is slightly more complicated. Figure 4 is a schematic diagram of the time frame structure of the LTE TDD system. As shown in the figure, a wireless time frame is also 10 ms, and may contain one or two special sub-time frames. The special sub-time frame is divided into three time slots: Downlink Pilot Time Slot (DwPTS), GP and Uplink Pilot Time slot (UpPTS); sub-time frame 0 and sub-time frame 5 And DwPTS is always used for downlink transmission, and other sub-time frames can be used for uplink transmission or downlink transmission as needed.

The length configuration of the three time slots of the special sub-time frame is as shown in Table 1. Table 1 shows all the configuration modes of the special sub-time frame area.

For the structure of the time frame in the LTE TDD system, another important configuration is the configuration of the uplink and downlink sub-timeframes. The specific configuration mode is shown in Table 2. The seven configurations are listed in Table 2, and D is used for downlink transmission. U indicates that it is used for uplink transmission, and S indicates that the sub-time frame is a special sub-time frame, which includes three parts: DwPTS, GP, and UpPTS.

The DwPTS domain can transmit the Physical Control Format Indicator Channel (PCFICH) and the entity downlink control. Physical downlink control channel (PDCCH), physical hybrid automatic repeat request (Physical HARQ Indicator Channel, PHICH), physical downlink shared channel (PDSCH) signal, and primary synchronization signal (Primary Synchronization) Signal, PSS), the UpPTS domain can transmit the Physical Random Access Channel (PRACH) and the Sounding Reference Signal (SRS), and cannot transmit the Physical Uplink Shared Channel (PUSCH). And physical Uplink Control Channel (PUCCH).

The inventors of the present invention have noticed in the course of the invention that in addition to the difference in the time frame structure, other differences between the FDD specification and the TDD specification in LTE mainly exist in the difference of the duplex mode itself, that is, the use of continuous sub-times under the FDD specification. The box works, and the uplink or downlink sub-frames are not continuous in time under the TDD specification, which results in some differences in uplink and downlink scheduling and retransmission timing and control procedures. However, in other basic transmission technologies, FDD and The TDD is identical, which also provides conditions for further integration of the two. The technical solution provided by the present invention mainly considers a fusion mode of FDD and TDD, that is, supporting both FDD UE and TDD on a pair of TDD carriers with some features. UE access, in order to implement such a hybrid access scheme (ie, enabling the system to implement hybrid access of FDD UEs and TDD UEs), and enabling the base station to schedule appropriate sub-timebox resources according to the UE's duplex specifications, a critical step It is to enable the base station to know the UE duplex specification message. That is, the communication system that provides both FDD and TDD can be made to provide a better communication service by providing the duplex specification of the UE; the embodiments of the present invention will be described below in conjunction with the drawings.

Two types of random access are defined in the LTE system: contention based random access and non-contention random access. Competition-based random access procedure as follows:

1. After the UE completes the community search, it reads the broadcast message, and obtains the PRACH channel resource configuration and the preamble configuration in the broadcast message.

2. The UE transmits a preamble sequence that can identify its identity on the time-frequency resource of the specific PRACH channel selected by the high-level algorithm, and performs uplink synchronization.

3. The base station detects the preamble sequence on the corresponding time-frequency resource, and after completing the sequence detection, sends a random access response.

4. After transmitting the preamble sequence, the UE detects the random access response sent by the base station in a subsequent period of time.

5. After detecting the random access response of the UE, the UE sends a resource scheduling request according to the content of the response and the requirement of the data service.

6. After receiving the scheduling request, the base station sends a response according to the actual load situation. If there is a conflict, send a conflict resolution response.

In the LTE system, the random access preamble sequence is carried by the physical layer PRACH channel. Each PRACH channel occupies one or more consecutive uplink sub-time frames in the time domain, and occupies 6 physical resource blocks in the frequency domain (Physical Resource, PRB). ). According to the design requirements of system access load and access delay, one or more PRACH channels can be configured in the system. These PRACH channels can be configured in different uplink sub-frames, or they can be configured in the same uplink sub-frame. Overlapping PRACH resources.

In view of this, the present invention provides an acquisition scheme of a UE duplex specification message.

Referring to FIG. 5, FIG. 5 is a schematic diagram of an implementation process of acquiring a UE duplex specification message. As shown in the figure, the following steps may be included when acquiring a UE duplex specification message: Step 501: The base station configures a mutually orthogonal PRACH channel resource set and/or a mutually orthogonal preamble sequence set for the UE of the first type of duplex specification type and the UE of the second type of duplex specification type; step 502, the base station Notifying, in the system broadcast, a configuration message including the configured mutually orthogonal PRACH channel resource set and/or mutually orthogonal preamble sequence set to the UE of the first type of duplex specification type and the second type of duplex specification type Step 503: The base station detects a random access signal, and the random access signal is selected by the UE in the PRACH channel resource set that matches the duplex specification type of the UE after the UE learns the configuration message, and/or Selecting a post-initiated random access signal from the preset preamble sequence set of the UE's duplex specification type; step 504, the base station according to the detected random access signal initiated by the UE, the PRACH channel time-frequency resource location and/or The preamble sequence determines the duplex specification type of the UE.

In this embodiment, the base station can be the UE of the first type of duplex specification type and the type of duplex type of the second type on the uplink carrier of the first type of duplex specification type and the second type of duplex specification type. The UE configures mutually orthogonal PRACH channel resource sets and/or mutually orthogonal preamble sequence sets.

In this embodiment, the mutually orthogonal set of PRACH channel resources may be a set of PRACH channel resources orthogonal to the time domain resources and/or orthogonal to the frequency domain resources.

In this embodiment, the first type of duplex specification type and the second type of duplex specification type may be two different ones of the following duplex specification types: FDD, TDD.

Referring to FIG. 6 , FIG. 6 is a schematic flowchart of a method for acquiring a UE duplex specification message. As shown in the figure, when acquiring a UE duplex specification message, the following steps may be included: Step 601: The base station is a first type duplex. The UE of the specification type and the UE of the second type of duplex specification configure the same PRACH channel resource set and the same preamble sequence set; in step 602, the base station notifies the configuration message in the system broadcast, where the configuration message includes the first type of double The PRACH channel resource set and the preamble sequence set that can be used by the UE of the specification type UE and the UE of the second type of duplex specification type; in step 603, the base station detects the random access signal, and the random access signal is that the UE is aware of the configuration. After the message, one of the PRACH channel resource sets is selected, and a post-initiated random access signal is selected in the preamble sequence set. Step 604: After detecting the random access signal initiated by the UE, the base station sends a random connection to the UE. Incoming a response message; and subsequently initiated for the UE The resource scheduling request allocates the uplink transmission resource; wherein the random access response sent by the base station to the UE of the first type of duplex specification type is the same as the random access response sent by the UE of the second type of duplex specification type; Step 605 The base station receives the duplex specification type message of the UE reported by the UE on the allocated uplink transmission resource.

Then, the base station sends the random access response message of the same format to the FDD UE and the TDD UE user; and allocates the uplink transmission resource for the subsequent UE resource scheduling request; at this time, the UE can report the uplink transmission resource on the allocated uplink transmission resource. Supported duplex specification messages, for example, are transmitted using a 1-bit (bit) message bit.

In another mode, the UE completes the uplink synchronization and the resource request through the contention-based random access procedure in the initial access process, and establishes an RRC connection with the base station in the subsequent process, and reports the capability information of the UE (including UE version message, UE level message, etc.).

In view of this, the embodiment of the present invention provides a UE duplex specification message. Get the plan.

The frequency interval requirement is required. In the specific implementation, the FDD uplink and downlink frequency interval requirement may be defined by the current stage radio frequency indicator, or may be a redefined radio frequency indicator requirement after the device level is improved in a certain stage in the future.

As shown in FIG. 9 , the TDD carrier 1 is configured as the uplink and downlink allocation mode 2, and the TDD carrier 2 is configured as the uplink and downlink allocation mode 0.

In this embodiment, the sub-time frames of each pair of TDD carriers may be out of synchronization, and the sub-time frame deviation time is an integer multiple of the sub-time frame length.

For example, the sub-time frames of two TDD carriers may also be out of synchronization, but the offset time is an integer multiple of the length of the sub-time frame.

In this embodiment, each pair of TDD carriers is not synchronized, and the uplink and downlink allocation modes of each pair of TDD carriers are configured the same; or each pair of TDD carriers is synchronized with the frame, and the uplink and downlink allocation of each pair of TDD carriers is performed. The mode configuration is different; or each pair of TDD carriers is not synchronized, and the uplink and downlink allocation modes of each pair of TDD carriers are configured differently.

The LTE-A TDD UE of the large bandwidth transmission is used; or the sub-timebox resources with different transmission directions configured on the at least two carriers can be simultaneously scheduled to the LTE-A TDD UE having the simultaneous receiving and transmitting capability on the two carriers. use.

For the two TDD carriers described above, any sub-timebox resources on each carrier can be scheduled for use by the TDD UE. E.g:

A), the sub-time frame resource on a single carrier can be provided to any TDD UE;

B), the sub-timebox resources with the same transmission direction configuration on the two carriers can be simultaneously scheduled for the LTE-ATDD UEs that need to support the large-bandwidth transmission; C), the sub-time frame resources with different transmission directions configured on the two carriers can be Simultaneously scheduled for use by LTE-A TDD UEs having simultaneous transmit/receive capabilities on one carrier (one carrier and one carrier).

In this embodiment, the sub-timebox resources with opposite transmission direction configurations on the two carriers can also be simultaneously scheduled for use by the FDD UE.

For example, for the two TDD carriers described above, the sub-timebox resources with opposite transmission direction configurations on the two carriers can be simultaneously scheduled for use by the FDD UE.

In this embodiment, when the same sub-timebox resource is configured on the two carriers, the DRX state may be configured for the FDD UE to reduce the power consumption of the UE.
