Description

Transmission configuration method and device thereof

Technical field

The present invention relates to the field of wireless communications, and in particular, to a transmission configuration method and an apparatus thereof.

Background technique

As the volume of mobile data continues to grow, spectrum resources become more and more tense. In some cases, only the use of licensed spectrum resources for network deployment and service transmission cannot meet the traffic demand. Therefore, the industry has proposed LTE-U (Unlicensed LTE). LTE unlicensed spectrum, where LTE is the abbreviation of Long Term Evolution, which is a long term evolution technology. LTE-U technology can deploy transmissions on unlicensed spectrum resources to improve user experience and extend coverage.

Unlicensed spectrum is not planned for specific application systems. It can be shared by multiple wireless communication systems such as Bluetooth and Wi-Fi. The shared unlicensed spectrum resources are used by multiple systems to seize resources. The unlicensed band is used as a secondary carrier to be assisted by the primary carrier of the licensed band.

The LTE system supports two duplex modes: FDD (Frequency Division Duplex) and TDD (Time Division Duplex), which are respectively represented as FDD-LTE and TDD-LTE. The two duplex modes use different modes. Frame structure.

FDD-LTE and TDD-LTE will adopt different licensed frequency bands respectively, so that the base station of the FDD system will only serve the terminal adopting the frame structure of the FDD system, and the base station of the TDD system can only serve the terminal adopting the frame structure of the TDD system. As a result, the base station cannot simultaneously serve two types of terminals supporting different frame structures. However, in unlicensed bands or in bands that do not specifically allocate dedicated spectrum for FDD systems or TDD systems, it is possible to coexist for these two types of terminals.

However, there is currently no solution for a base station to simultaneously schedule different types of terminals and transmit configurations for the two types of terminals.

detailed description

The present invention will be further described in detail with reference to the accompanying drawings, in which . All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The following is a description of some of the various embodiments of the invention, which are intended to provide a basic understanding of the invention, and are not intended to identify key or critical elements of the invention. According to the technical solution of the present invention, other implementations can be obtained by replacing each other without changing the spirit of the present invention.

Embodiment 1

1A is a schematic flowchart of a transmission configuration implemented on a network side according to Embodiment 1 of the present invention, as shown in the figure. The process can include the following steps:

Step 101: The network device determines the scheduled terminal, where the scheduled terminal includes a first type terminal and a second type terminal, and the first type terminal only supports a partial subframe.

Step 102: The network device sends signaling to the scheduled first type of terminal, where the signaling is used to indicate a subframe or a subframe set that the first type of terminal does not need to listen to.

In the foregoing process, the network device may be a base station, such as an eNB (evolved NodeB, an evolved Node B) in an LTE system, or another network device having a wireless access function.

Based on the flow shown in FIG. 1A, FIG. 1B is a schematic diagram of a transmission configuration process implemented on the terminal side according to Embodiment 1 of the present invention. As shown in the figure, the process may include the following steps:

Step 110: The first type of terminal receives the signaling sent by the network device, where the first type of terminal is a terminal that is scheduled by the network device, and the terminal that is scheduled by the network device includes a first type terminal and a second type terminal. The first type of terminal only supports a partial subframe. The method for the network device to send the signaling is the same as the process shown in FIG. 1B.

Step 111: The terminal determines, according to the signaling, a subframe or a subframe set that does not need to be monitored.

Further, after the step 111, the first type of terminal may not monitor the subframe or the subframe set indicated by the signaling according to the signaling, and perform monitoring for other subframes.

When the first type of terminal listens to the subframe, at least the PDCCH or other channel for carrying the control information, such as ePDCCH, is decoded, so that the control information carried on the channel is obtained, for example, the control. The information may include information such as transmission format, resource allocation, uplink scheduling grant, power control, and uplink retransmission information.

Further, the first type of terminal may further perform CSI (Channel State Information) measurement by using a subframe monitoring process, where the CSI may include a CQI (Channel Quality Indicator) and an RI (rank indication). , rank indication), PMI (Precoding Matrix Indicator, precoding matrix indicator) and other information.

Further, the first type of terminal may perform RRM (Radio Resource Management) measurement by using a subframe monitoring process, that is, performing RSRP (Reference Signal Receiving Power) and RSRQ (Reference Signal Receiving). Measurement of information such as Quality, reference signal reception quality).

In the foregoing process shown in FIG. 1A and FIG. 1B, the scheduled terminal may include a first type terminal and a second type terminal. The first type of terminal supports only a part of the subframes, and the second type of terminal supports other subframes in addition to the subframes supported by the first type of terminal. For example, the first type of terminal only supports the downlink subframe, and the second type of terminal supports the uplink subframe and the downlink subframe. The first type of terminal may support a first type of frame structure, and the second type of terminal may support a second type of frame structure. For example, the radio frame of the first type of frame structure is an FDD radio frame, and the radio frame of the second type of frame structure is a TDD radio frame.

FIG. 2A exemplarily shows a first type of frame structure. As shown in the figure, a radio frame contains 10 1ms. Subframe, one sub-frame contains two 5ms long slots. In a radio frame, all subframes are uplink subframes or all subframes are downlink subframes.

FIG. 2B exemplarily shows a second type of frame structure. As shown in the figure, one radio frame contains two 5ms long half frames, and one half frame contains five 1ms long subframes. The 10 subframes included in a radio frame include both an uplink subframe and a downlink subframe.

In the foregoing process shown in FIG. 1A and FIG. 1B, the network device may send the signaling in multiple manners. Preferably, the signaling may be sent by a PDCCH (Physical Downlink Control Channel) or an Enhanced Physical Downlink Control Channel (ePDCCH). Further, DCI (Downlink Control Information, The downlink control information carries the signaling, and of course, does not exclude the use of other bearers to transmit the signaling.

Further, the network device may further notify, by using signaling, subframe configuration information of the radio frame to which the first type terminal and the second type terminal are scheduled, to the second type terminal, so that the second The class terminal obtains uplink and downlink configuration information of the radio frame, so that the first type terminal performs uplink data transmission and downlink data reception according to the subframe configuration information. The radio frame to which the first type of terminal and the second type of terminal are scheduled may be a radio frame of the LTE-TDD, and may of course not be limited to the radio frame structure of the LTE-TDD.

In the above process, preferably, the subframe that does not need to be monitored is an uplink subframe, so that the first type of terminal can only use the downlink subframe for downlink data transmission, and the second type of terminal can further use the uplink subframe. Uplink data transmission. Further, the first type of terminal and the second type of terminal may multiplex downlink subframes on the same carrier for downlink data transmission. For example, if the first type of terminal is a terminal supporting an FDD-LTE frame structure, the second type of terminal is a terminal supporting a TDD-LTE frame structure, and the wireless frames scheduled by the two types of terminals include both uplinks. The subframe further includes a downlink subframe, and the base station may send the information of the subframe that is capable of identifying the subframe, such as the frame number of the uplink subframe in the radio frame, to the terminal supporting the FDD-LTE frame structure, so that the terminal does not need to be configured. Listen for these uplink subframes.

In the foregoing process, the subframe that is not required to be monitored by the signaling may be located in the radio frame where the signaling is located, that is, the signaling indicating to the first type of terminal that the current radio frame does not need to be monitored by using the signaling. A sub-frame or a collection of sub-frames. The subframe that is not required to be monitored by the signaling may also be located in the next radio frame of the radio frame in which the signaling is located, that is, the next type of terminal is indicated by the signaling to the next radio frame. A sub-frame or a collection of sub-frames that do not need to be monitored in a radio frame. The subframes that do not need to be monitored indicated by the signaling may also be located in a set time window, that is, the subframes or subframe sets that do not need to be monitored in the time window are indicated to the first type of terminal by the signaling. . The length of the time window can be set as needed. By setting a time window to indicate a subframe or a subframe set that does not need to be monitored in the time window, the terminal can be more flexibly configured for transmission.

In the step 102 of the foregoing process, the carrier used by the network device to send the signaling may be the same as or different from the carrier to which the first type terminal and the second type terminal are scheduled, that is, the network device may adopt The cross-carrier or co-carrier mode indicates that the first type of terminal indicates a subframe or a set of subframes that do not need to be monitored.

Preferably, the carrier used by the network device to send the signaling is a primary carrier, and the carrier to which the first type terminal and the second type terminal are scheduled is a secondary carrier. For example, in the case of allocating the transmission resources of the unlicensed band to the first type terminal and the second type terminal, the network device may use the primary carrier of the licensed frequency band to schedule the secondary carrier of the first type terminal and the second type terminal in the unlicensed frequency band. Data transfer is performed.

In the foregoing process, the carrier used by the network device to send the signaling may be a carrier on a licensed frequency band or a carrier on an unlicensed frequency band. If the carrier used by the network device to send the signaling is the primary carrier on the licensed frequency band, the primary carrier on the licensed frequency band may adopt the first type of frame structure or the second type of frame structure.

In the foregoing process, the first type terminal and the second type terminal may be scheduled to be used on a carrier of a licensed frequency band, or may be scheduled to a carrier of an unlicensed frequency band.

Further, in the case that the carrier to which the first type terminal and the second type terminal are scheduled is a carrier on the unlicensed frequency band, the network device may adopt a combination of one or more of the following manners to be scheduled. The first type of terminal sends signaling to indicate a subframe or a set of subframes that the first type of terminal does not need to listen to:

Mode 1: The network device sends the signaling in a first subframe in a first radio frame, where the signaling is used to indicate that the first type of terminal is in the first radio frame on a carrier of an unlicensed frequency band. A collection of subframes or subframes that do not need to be listened to. Preferably, the first subframe is subframe 0, and may of course be other subframes. In this way, one of the radio frames can be used to indicate a subframe or a set of subframes in the radio frame that need not be monitored by the first type of terminal.

Mode 2: The network device sends the signaling in a second subframe of the first radio frame, where the signaling is used to indicate that the first type of terminal does not need to be in a second radio frame on an unlicensed band carrier. A monitored subframe or a set of subframes, the second radio frame being a next radio frame of the first radio frame. Preferably, the second word frame is a subframe 5, and may of course be other subframes. In this manner, one subframe of one radio frame may be used to indicate that the next radio frame does not need to be the first type of terminal. The monitored subframe or collection of subframes.

In order to explain the

above modes

1 and 2 more clearly, the following description will be made with reference to FIGS. 3A, 3B, 4A, and 4B.

3A and 3B illustrate an example in which a network device uses a carrier on a licensed band to transmit signaling to indicate a set of subframes that the first type of terminal does not need to listen to. The carrier on the licensed band can be the primary carrier. The licensed frequency band carrier adopts a first type of frame structure. For example, a subframe in one radio frame is a downlink subframe, a carrier in an unlicensed frequency band may be a secondary carrier, and an unlicensed frequency band carrier adopts a second type of frame structure, and the primary carrier and the primary carrier are The secondary carrier maintains subframe alignment. The first type of terminal and the second type of terminal are scheduled to be on the same unlicensed frequency band carrier, that is, the two types of terminals share one unlicensed carrier, and the first type of terminal receives data transmission in the downlink subframe. 3A and 3B only show an example in which the primary carrier is all downlink subframes, and it is of course not excluded that the primary carrier adopts the second type of frame structure.

As shown in FIG. 3A, the licensed band primary carrier may indicate, in subframe 0 or other subframes, the PDCCH or the ePDCCH cross-carrier to the first type of terminal, indicating that the unlicensed-band secondary carrier does not need to listen to the subframe set in the current radio frame. For example, the subframe 2, the subframe 3, and the subframe 4 shown in the figure are all uplink subframes. The indication of the set of subframes can be bitmapped The mode indicates, for example, for a radio frame having 10 subframes, 10 bits can be used to indicate which subframe or subframes in the radio frame do not need to be monitored, wherein one bit is for one subframe in the radio frame.

As shown in FIG. 3B, in the subframe 5 or other subframes, the PDCCH or the ePDCCH cross-carrier indicates to the first type of terminal that the unlicensed-band secondary carrier does not need to listen to the subframe set in the next radio frame, for example, The subframe 2, the subframe 3, and the subframe 4 in the next radio frame shown in the figure are all uplink subframes. The indication of the set of subframes can be indicated in the form of a bitmap.

4A and 4B illustrate an example in which a network device transmits signaling using a carrier on an unlicensed band to indicate a set of subframes that the first type of terminal does not need to listen to. The unlicensed frequency band secondary carrier adopts a second type of frame structure. The first type of terminal and the second type of terminal are scheduled to be on the same unlicensed frequency band carrier, that is, the two types of terminals share one unlicensed carrier, and the first type of terminal receives data transmission in the downlink subframe.

As shown in FIG. 4A, the unlicensed band carrier may use the PDCCH or the ePDCCH to indicate to the first type of terminal that the unlicensed band carrier does not need to listen to the subframe set in the current radio frame by using the PDCCH or the ePDCCH. For example, the subframe 2, the subframe 3, and the subframe 4 shown in the figure are all uplink subframes. The indication of the set of subframes can be indicated in the form of a bitmap.

As shown in FIG. 4B, the unlicensed band carrier in the subframe 5 or other subframes, through the PDCCH or the ePDCCH, uses the carrier to indicate to the first type of terminal that the unlicensed band carrier does not need to listen to the subframe set in the next radio frame. For example, the subframe 2, the subframe 3, and the subframe 4 in the next radio frame shown in the figure are all uplink subframes. The indication of the set of subframes can be indicated in the form of a bitmap.

In step 101 of the foregoing process, the network device may further determine transmission resources used by the scheduled first type terminal and the second type terminal, that is, allocate transmission resources to the scheduled terminal. The transmission resources allocated to the first type of terminal and the second type of terminal may be transmission resources located in the same frequency band. For example, the first type of terminal and the second type of terminal may be allocated the same carrier. That is, the first type of terminal and the second type of terminal are scheduled to the same carrier. Further, the carrier may be a carrier in a licensed frequency band, a carrier in an unlicensed frequency band, or a carrier in another frequency band.

If the first type of terminal and the second type of terminal are scheduled to be on the same carrier, time division multiplexing, frequency division multiplexing, space division multiplexing, or code division multiplexing may be adopted. In a manner, the scheduled first type terminal and the second type terminal use the carrier for data transmission.

For example, if the first type of terminal and the second type of terminal are scheduled to transmit data to downlink subframes in the same radio frame of the same carrier, both types of terminals can receive the network device transmission in the downlink subframe. signal. In this case, the first type of terminal and the second type of terminal may respectively occupy different frequency bands of the carrier to distinguish different types of terminals, that is, allocate different frequency resources for the two types of terminals, so that the first type of terminal and the first type The second type of terminal shares the carrier by means of frequency division multiplexing.

Optionally, a space division multiplexing manner, such as DL-MIMO (Downlink Multi-Input Multi-Output, In the downlink-multiple input multiple output mode, the first type of terminal and the second type of terminal share the same frequency domain resource and downlink subframe.

Optionally, the first type of terminal and the second type of terminal may be distinguished by orthogonal or non-orthogonal spreading codes, so that the first type of terminal and the second type of terminal use different spreading codes. Thereby, the downlink subframes on the same carrier are shared in a code division multiplexing manner. Further, for the uplink subframe on the carrier, only the second type of terminal can use the signal transmission.

Optionally, the network device may sequentially configure the radio frame of the first type of frame structure and the radio frame of the second type of frame structure on the same carrier according to actual service requirements. The radio frame of the first type of frame structure may be allocated only to the first type of terminal for data transmission, and the radio frame of the second type of frame structure may be allocated only to the second type of terminal for data transmission, thereby making the first type of terminal and the second type The terminals share the same carrier in a time division multiplex manner. FIG. 5 shows a schematic diagram of implementing time division multiplexing by sequentially configuring a radio frame of a first type of frame structure and a radio frame of a second type of frame structure.

As can be seen from the above description, the network device can schedule different types of first type terminals and second type terminals, wherein the first type of terminals support partial subframes, and notify the first type of terminals therein to be scheduled by signaling. A subframe or a set of subframes that need to be monitored or not monitored on the transmission resource to be implemented, thereby implementing scheduling and transmission configuration for two types of terminals of different types.

For example, if the foregoing embodiment is applied to an LTE system, since the LTE system supports two duplex modes, FDD and TDD, respectively, different frame structures are supported. For terminals supporting the FDD frame structure, the terminal can be notified that it is scheduled. The uplink transmission frame does not need to be monitored for the uplink subframe, and the terminal supporting the TDD frame structure can notify the terminal of the subframe configuration information, so that the terminal supporting the FDD frame structure uses the downlink subframe for data transmission, so that the terminal transmits the downlink subframe. A terminal supporting a TDD frame structure uses an uplink subframe and a downlink subframe for data transmission. In particular, in an uplink and downlink subframe configuration in which the uplink subframe is relatively large, the terminal supporting the FDD frame structure does not listen to the uplink subframe, which is advantageous for the terminal to save power better.
