Description

Transmission configuration method and equipment thereof

Technical Field

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

Background

With the continuous increase of mobile data traffic, spectrum resources are increasingly tense, and in some cases, network deployment and service transmission performed by using authorized spectrum resources cannot meet traffic requirements, so the industry proposes LTE-U (Unlicensed LTE, LTE is an english abbreviation of Long Term Evolution, that is, Long Term Evolution) technology. LTE-U technology may deploy transmissions on unlicensed spectrum resources to improve user experience and extend coverage.

The unlicensed spectrum does not plan a specific application system, can be shared by various wireless communication systems such as Bluetooth and Wi-Fi, and uses shared unlicensed spectrum resources among various systems in a resource preemption mode. The unlicensed frequency band is used as an auxiliary carrier and is realized by the main carrier of the licensed frequency band in an auxiliary mode.

The LTE system supports two duplex modes, FDD (Frequency division duplex) and TDD (Time division duplex), which are respectively denoted as FDD-LTE and TDD-LTE, and the two duplex modes use different frame structures.

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

However, there is no solution for a base station to simultaneously schedule different types of terminals and perform transmission configuration for the two types of terminals.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The following description is of some of the several embodiments of the present invention in order to provide a basic understanding of the invention and is not intended to identify key or critical elements of the invention or to delineate the scope of the invention. According to the technical scheme of the invention, other implementation modes can be obtained by mutual replacement without changing the essential spirit of the invention.

Example one

Referring to fig. 1A, a schematic diagram of a transmission configuration flow implemented on a network side according to an embodiment of the present invention is shown, where the flow may include the following steps:

step 101: the method comprises the steps that network equipment determines scheduled terminals, wherein the scheduled terminals comprise first-class terminals and second-class terminals, and the first-class terminals only support partial subframes;

step 102: the network equipment sends signaling to the scheduled first-class terminal, wherein the signaling is used for indicating the subframe or the subframe set which the first-class terminal does not need to monitor.

In the above procedure, the network device may be a base station, such as an eNB (evolved NodeB ) in an LTE system, or may be other network devices with a radio access function.

Based on the flow shown in fig. 1A, fig. 1B shows a schematic diagram of a transmission configuration flow implemented on a terminal side according to an embodiment of the present invention, as shown in the figure, the flow may include the following steps:

step 110: a first type terminal receives a signaling sent by network equipment; the first class of terminals are terminals scheduled by network equipment, the terminals scheduled by the network equipment comprise first class terminals and second class terminals, and the first class terminals only support partial subframes. The method for the network device to send the signaling is the same as the flow shown in fig. 1B.

Step 111: and the terminal determines the subframes or the subframe set which do not need to be monitored according to the signaling.

Further, after step 111, the first class terminal may not monitor the subframe or the subframe set indicated by the signaling according to the signaling, and monitor other subframes.

When the first type terminal monitors a subframe, at least a PDCCH or other channels for carrying control information, such as an ePDCCH, in the subframe is decoded to obtain the control information carried on the channel, for example, the control information may include information such as a transmission format, resource allocation, uplink scheduling grant, power control, and uplink retransmission information.

Further, the first type of terminal may also perform CSI (Channel State Information) measurement through a subframe monitoring process, where the CSI may include Information such as a CQI (Channel Quality Indicator), an RI (rank indication), a PMI (Precoding Matrix Indicator), and the like.

Further, the first class of terminals may also perform RRM (Radio Resource Management) measurement through a subframe monitoring process, that is, measurement of information such as RSRP (Reference Signal Receiving Power) and RSRQ (Reference Signal Receiving Quality).

In the above-mentioned flows shown in fig. 1A and fig. 1B, the scheduled terminals may include a first class terminal and a second class terminal. The first class of terminals only support partial subframes, and the second class of terminals also support other subframes besides the subframes supported by the first class of terminals. For example, the first type of terminal only supports downlink subframes, and the second type of terminal supports uplink subframes and downlink subframes. 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 with the first type of frame structure is an FDD radio frame, and the radio frame with the second type of frame structure is a TDD radio frame.

Fig. 2A exemplarily shows a first type frame structure. As shown, one radio frame includes 101 ms subframes, and one subframe includes 2 slots (slots) of 5ms length. 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, a radio frame includes 2 fields of 5ms length, and a field includes 5 subframes of 1ms length. The 10 subframes included in one radio frame include both uplink subframes and downlink subframes.

In the above-described flows shown in fig. 1A and fig. 1B, the network device may send the signaling in various manners. Preferably, the signaling may be sent through a PDCCH (Physical Downlink Control Channel) or an ePDCCH (enhanced Physical Downlink Control Channel), and further, the signaling may be carried by a DCI (Downlink Control Information), which certainly does not exclude that other carrying manners are used to send the signaling.

Further, the network device may also notify the subframe configuration information of the radio frame to which the first class terminal and the second class terminal are scheduled to the second class terminal through a signaling, so that the second class terminal obtains the uplink and downlink configuration information of the radio frame, and the first class 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 LTE-TDD, and certainly may not be limited to the radio frame structure of LTE-TDD.

In the above flow, 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 for uplink data transmission. Further, the first class terminal and the second class 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 radio frames to which the two types of terminals are scheduled include both uplink subframes and downlink subframes, the base station may send information that can identify the subframes, such as frame numbers of the uplink subframes in the radio frames, to the terminals supporting the FDD-LTE frame structure through signaling, so that the terminals do not need to monitor the uplink subframes.

In the above procedure, the subframe that does not need to be monitored and indicated by the signaling may be located in the radio frame where the signaling is located, that is, the subframe or the subframe set that does not need to be monitored in the current radio frame is indicated to the first type terminal through the signaling. The subframe not required to be monitored, which is indicated by the signaling, may also be located in the next radio frame of the radio frame where the signaling is located, that is, the subframe or the subframe set not required to be monitored in the next radio frame of the current radio frame is indicated to the first class terminal through the signaling. The subframes which do not need to be monitored and are indicated by the signaling may also be located in a set time window, that is, the subframes or the set of subframes which do not need to be monitored in the time window are indicated to the first class terminal through the signaling. The length of the time window can be set as desired. And indicating the subframes or the subframe set which does not need to be monitored in the time window in a mode of setting the time window, so that the transmission configuration can be more flexibly carried out on the terminal.

In step 102 of the above procedure, 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 class of terminal and the second class of terminal are scheduled, that is, the network device may indicate a subframe or a subframe set that does not need to be monitored for the first class of terminal in a cross-carrier or same-carrier manner.

Preferably, the carrier used by the network device to send the signaling is a primary carrier, and the carriers to which the first class of terminals and the second class of terminals are scheduled are secondary carriers. For example, in a case where transmission resources in an unlicensed frequency band are allocated to a first class of terminal and a second class of terminal, the network device may schedule the first class of terminal and the second class of terminal to perform data transmission on an auxiliary carrier in the unlicensed frequency band by using a main carrier in the licensed frequency band.

In the above procedure, the carrier used by the network device to send the signaling may be a carrier on an authorized frequency band, or may be a carrier on an unauthorized frequency band. If the carrier used by the network device to send the signaling is a main carrier on the authorized frequency band, the main carrier on the authorized frequency band may adopt a first-type frame structure or a second-type frame structure.

In the above procedure, the first class terminal and the second class terminal may be scheduled to a carrier in an authorized frequency band, and may also be scheduled to a carrier in an unauthorized frequency band.

Further, in the case that the carrier to which the first class terminal and the second class terminal are scheduled is a carrier on an unlicensed frequency band, the network device may send a signaling to the scheduled first class terminal in one or a combination of the following manners to indicate a subframe or a subframe set that the first class terminal does not need to monitor:

mode 1: the network equipment sends the signaling in a first subframe in a first wireless frame, and the signaling is used for indicating a subframe or a subframe set which the first class of terminals do not need to monitor in the first wireless frame on a carrier of an unlicensed frequency band. Preferably, the first subframe is subframe 0, but may be other subframes. In this way, one subframe in one radio frame may 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: and the network equipment sends the signaling in a second subframe of the first radio frame, wherein the signaling is used for indicating a subframe or a subframe set which does not need to be monitored in a second radio frame of the first class of terminals on the unlicensed frequency band carrier, and the second radio frame is the next radio frame of the first radio frame. Preferably, the second word frame is subframe 5, but may also be other subframes, and in this way, one subframe in one radio frame may be used to indicate a subframe or a subframe set that is not required to be monitored by the first type terminal in the next radio frame.

In order to more clearly explain the above mode 1 and mode 2, description will be made below with reference to fig. 3A, fig. 3B, fig. 4A, and fig. 4B.

Fig. 3A and 3B show examples of a network device sending signaling using a carrier on a licensed frequency band to indicate a set of subframes that a first type of terminal does not need to listen to. The carrier on the licensed band may be a primary carrier. The authorized frequency band carrier adopts a first type of frame structure, for example, a subframe in a radio frame is a downlink subframe, the carrier of the unauthorized frequency band can be an auxiliary carrier, the carrier of the unauthorized frequency band adopts a second type of frame structure, and the alignment of the subframe is maintained by the main carrier and the auxiliary carrier. The first type of terminal and the second type of terminal are scheduled to the same unlicensed frequency band carrier, namely the two types of terminals share one unlicensed carrier, and the first type of terminal receives data transmission in a downlink subframe. Fig. 3A and 3B only illustrate examples in which the primary carriers are all downlink subframes, and certainly do not exclude the case where the primary carriers adopt the second type of frame structure.

As shown in fig. 3A, the licensed band primary carrier may indicate, in subframe 0 or other subframes, a subframe set, such as subframe 2, subframe 3, and subframe 4 shown in the figure, to the first class of terminals through a PDCCH or ePDCCH cross carrier, where the unlicensed band secondary carrier does not need to be monitored in the current radio frame, and these subframes are all uplink subframes. The indication of the subframe set may be indicated by means of bitmap, for example, for a radio frame with 10 subframes, 10 bits may 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 subframe 5 or other subframes, the primary carrier in the authorized frequency band indicates, through a PDCCH or ePDCCH cross-carrier, a subframe set to which the secondary carrier in the unlicensed frequency band does not need to monitor in the next radio frame to the first class of terminals, for example, subframe 2, subframe 3, and subframe 4 in the next radio frame shown in the figure, and these subframes are uplink subframes. The indication of the subframe set may be indicated in a bitmap manner.

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

As shown in fig. 4A, the unlicensed band carrier may be in subframe 0 or other subframes, and a set of subframes that the unlicensed band carrier does not need to monitor in the current radio frame, such as subframe 2, subframe 3, and subframe 4 shown in the figure, is indicated to the first type of terminal through a PDCCH or an ePDCCH by using the carrier. The indication of the subframe set may be indicated in a bitmap manner.

As shown in fig. 4B, in subframe 5 or other subframes, the unlicensed band carrier is used to indicate, to the first type of terminal, a subframe set that the unlicensed band carrier does not need to monitor in the next radio frame through a PDCCH or an ePDCCH, for example, subframe 2, subframe 3, and subframe 4 in the next radio frame shown in the figure are uplink subframes. The indication of the subframe set may be indicated in a bitmap manner.

In step 101 of the above process, the network device may further determine transmission resources used by the scheduled first class terminal and the scheduled second class terminal, that is, allocate transmission resources for the scheduled terminals. The transmission resources allocated to the first class of terminals and the second class of terminals may be transmission resources located in the same frequency band, for example, the same carrier may be allocated to the first class of terminals and the second class of terminals, that is, the first class of terminals and the second class of terminals 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 class terminal and the second class terminal are scheduled to the same carrier, the scheduled first class terminal and the scheduled second class terminal can use the carrier to perform data transmission by adopting a time division multiplexing mode, a frequency division multiplexing mode, a space division multiplexing mode or a code division multiplexing mode.

For example, if the first type of terminal and the second type of terminal are scheduled to downlink subframes in the same radio frame of the same carrier for data transmission, both types of terminals may receive signals transmitted by the network device in the downlink subframes. At this time, the first class terminal and the second class terminal may respectively occupy different frequency bands of the carrier to distinguish different types of terminals, that is, different frequency resources are allocated to the two classes of terminals, so that the first class terminal and the second class terminal share the carrier in a frequency division multiplexing manner.

Alternatively, a space division multiplexing manner, such as a DL-MIMO (Downlink Multi-Input Multi-Output, Downlink-multiple Input multiple Output) manner, may also be adopted, so that the first class of terminals and the second class of terminals share the same frequency domain resource and Downlink subframe.

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

Optionally, the network device may sequentially and respectively configure the radio frame with the first type of frame structure and the radio frame with the second type of frame structure on the same carrier according to actual service requirements. The radio frame with the first type frame structure can be only allocated to the first type terminal for data transmission, and the radio frame with the second type frame structure can be only allocated to the second type terminal for data transmission, so that the first type terminal and the second type terminal share the same carrier wave in a time division multiplexing mode. Fig. 5 shows a schematic diagram of implementing time division multiplexing by sequentially configuring a radio frame with a first type frame structure and a radio frame with a second type frame structure.

As can be seen from the above description, the network device may schedule different types of first class terminals and second class terminals, where the first class terminals support partial subframes, and notify, through signaling, a subframe or a subframe set in which the first class terminals need or do not need to monitor on the scheduled transmission resources, so as to implement scheduling and transmission configuration for the two types of terminals of different types.

For example, if the above embodiment is applied to an LTE system, since the LTE system supports two duplex modes, namely FDD and TDD, and supports different frame structures, for a terminal supporting an FDD frame structure, the terminal may be notified that it is not required to monitor an uplink subframe on a scheduled transmission resource, and for a terminal supporting a TDD frame structure, subframe configuration information may be notified to the terminal, so that the terminal supporting an FDD frame structure performs data transmission using a downlink subframe, and the terminal supporting a TDD frame structure performs data transmission using an uplink subframe and a downlink subframe. Particularly, in the configuration of the uplink and downlink subframes with more uplink subframes, the terminal supporting the FDD frame structure does not monitor the uplink subframes, which is beneficial to better saving electricity for the terminal.

Example two

Referring to fig. 6A, a schematic diagram of a transmission configuration flow implemented on a network side according to a second embodiment of the present invention is shown, where the flow may include the following steps:

step 601: the method comprises the steps that network equipment determines scheduled terminals, wherein the scheduled terminals comprise first-class terminals and second-class terminals, and the first-class terminals only support partial subframes;

step 602: the network equipment sends signaling to the scheduled first-class terminal, and the signaling is used for indicating the subframe or the subframe set which the first-class terminal needs to monitor.

In the above procedure, the network device may be a base station, such as an eNB in an LTE system, or may be another network device with a radio access function.

Based on the flow shown in fig. 6A, fig. 6B shows a schematic diagram of a transmission configuration flow implemented on a terminal side according to a second embodiment of the present invention, as shown in the figure, the flow may include the following steps:

step 610: a first type terminal receives a signaling sent by network equipment; the first class of terminals are terminals scheduled by network equipment, the terminals scheduled by the network equipment comprise first class terminals and second class terminals, and the first class terminals only support partial subframes. The method for the network device to send the signaling is the same as the flow shown in fig. 6A.

Step 611: and the terminal determines the subframe or the subframe set which needs to be monitored according to the signaling.

As can be seen from the above flow, the difference between the second embodiment and the first embodiment is: the network equipment indicates the subframe or the subframe set of the first type terminal to be the subframe or the subframe set which the first type terminal needs to monitor through signaling. Accordingly, the first type terminal may determine the subframe or the subframe set to be monitored according to the signaling.
