Description

Signaling configuration and transmission method, site, terminal, computer storage medium

Technical field

The present invention relates to communications technologies, and in particular, to an unlicensed carrier-based signaling configuration and transmission method, a station, a terminal, and a computer storage medium in a Long Term Evolution (LTE) system.

Background technique

At present, LTE communication networks are deployed in licensed carriers. With the development of LTE, some companies have proposed "recommending research on LTE deployment in unlicensed carriers." For example, Qualcomm of the United States believes that: With the rapid growth of business, in the near future, authorized carriers will not be able to withstand the huge amount of data brought by rapid business growth. Considering that LTE is deployed in an unlicensed carrier to share the data traffic in the authorized carrier, the data volume pressure brought by the service growth can be solved. At the same time, the unlicensed carrier has the following characteristics: on the one hand, since the unlicensed carrier does not need to be purchased, or the carrier resource is zero cost, the unlicensed carrier is free or low-cost; on the other hand, since the individual and the enterprise can participate in the deployment, the device The device's equipment can also be deployed, so the admission requirements of the unlicensed carrier are low. Moreover, the unlicensed carrier is shared. When multiple different systems are operating or when different operators of the same system are operating, some can be considered. Ways to share resources to improve carrier efficiency.

In summary, although LTE deployment has obvious advantages in unlicensed carriers, in the process of deployment, there are still problems: multiple wireless access technologies (cross-communication standards, difficult collaboration, diverse network topologies) and There are many wireless access sites (the number of users is large, the collaboration is difficult, and the centralized management overhead is large). Due to the large number of wireless access technologies, there will be various wireless systems in the unlicensed carrier, which are difficult to coordinate with each other and have serious interference. Therefore, for LTE deployed in unlicensed carriers, there is still a need to support the regulation of unlicensed carriers. Most countries require the system to be unlicensed. When deploying in the wave, you need to support the LBT (Listen Before Talk) mechanism. By listening to the mechanism first, it is possible to avoid interference caused by the simultaneous use of unlicensed carriers between adjacent systems. And the competition back-off mechanism is further introduced, that is, the neighboring system sites (generally the neighboring transmission nodes of the same system) can avoid the interference caused by the neighboring transmission nodes of the same system simultaneously using the unlicensed carriers through the contention back-off mechanism.

After the LTE is executed by the unlicensed carrier, the mechanism of the listening and speaking mechanism brings some problems, such as the occupation time of the station occupation period, the uplink period during the occupation period, the downlink subframe position and the number, and the transmission of various reference signals. How to configure and how to send these signalings to the terminal enables the terminal to quickly receive the subframes, thereby performing data reception and measurement, etc., which is a problem to be solved.

detailed description

The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

FIG. 1 is a schematic flowchart of a signaling configuration method according to an embodiment of the present invention. The signaling configuration method in this example is applied to a site. As shown in FIG. 1 , the signaling configuration method includes the following steps:

Step 101: After the station preempts the unlicensed carrier usage right, the station configures signaling for the subframe, where the configuration signaling includes configuring one or more of the following parameters in a partial subframe or all subframes.

The first parameter is used to indicate the number of consecutive occupied subframes from the current subframe; the second parameter is used to indicate the number of subframes after the last subframe from the downlink; and the third parameter is used to indicate the subframe or The number of CRS symbols in the subframe in the burst transmission, or whether it is an MBSFN subframe; the fourth parameter, the fifth parameter, and the sixth parameter are used to indicate whether the CSI-RS and/or CSI are configured or specifically configured in the subframe. The first parameter is used to indicate the power of the CRS/CSI-RS of the subframe in the subframe or the burst transmission; the eighth parameter is used to indicate the burst number; and the ninth parameter is used to indicate whether the burst transmission is There is an uplink subframe; a tenth parameter, which is used to directly or indirectly indicate the number of OFDM symbols of the last downlink subframe; and an eleventh parameter, which is used to indicate whether a DRS exists in the subframe.

The above parameters in the embodiments of the present invention are all physical layer parameters, and each parameter is described in detail.

The first parameter: the number of bits of the first parameter is based on the maximum number of downlink subframes in the burst transmission Determining, by the first parameter, the number of consecutive subframes (such as the downlink subframe or the uplink subframe or the uplink and downlink) from the current subframe (including the current subframe), by converting the first parameter into a decimal Add 1 to the number. Specifically, if there are at most 13/10 downlink subframes in a burst transmission, 4 bits are used to indicate the first parameter; if other values are used, the corresponding number of bits also needs to be adjusted.

The second parameter: the number of bits of the second parameter is determined according to the maximum number of uplink subframes in the burst transmission; the number of subframes after the last subframe from the downlink indicated by the second parameter is converted into the second parameter by Add 1 to the decimal number. Specifically, if there are at most 13/10 uplink subframes in a burst transmission, 4 bits are used to represent the second parameter; if other values are used, the corresponding number of bits also needs to be adjusted.

The third parameter: the number of bits of the third parameter is the number of downlink subframes or the number of downlink subframes in the consecutive subframes indicated by the first parameter minus 1 or a fixed number of bits or a fixed number of bits; the third parameter is bitmap The mode indicates the number of CRS symbols in the subframe, or whether it is an MBSFN subframe; where the bit in the third parameter is 1, indicating that the number of CRS symbols is 1 or 2 or an MBSFN subframe; When the bit is 0, it indicates that the number of CRS symbols is 4 or 6 or a non-MBSFN subframe. When the number of bits of the third parameter is 1, the third parameter is used to indicate the number of CRS symbols in the current subframe, or whether it is an MBSFN subframe.

In the case of using the bitmap, the third parameter is used by a maximum of 8 bits (the cost of the following two subframes has been subtracted), and the site is specified at this time (the signaling in the embodiment of the present invention is a device using an unlicensed carrier) The maximum duration of the single occupancy is 10 ms, and when there are subframe 0 and subframe 5 in the subframe within the occupied duration, the station does not configure subframe 0 and subframe 5 as MBSFN subframes. The number of bits of the specific third parameter is still dynamically determined according to the first parameter description, but if the downlink subframe includes subframe 0 or subframe 5, the corresponding bit overhead needs to be subtracted.

Or, in the case of adopting the bitmap, the third parameter is used by a maximum of 11 bits, and the site is specified at this time (the signaling in the embodiment of the present invention is applicable to devices using an unlicensed carrier) The maximum duration of a single occupation is 13 ms, and when there are subframe 0 and subframe 5 in the subframe within the occupied duration, the station does not configure subframe 0 and subframe 5 as MBSFN subframes. The number of bits of the specific third parameter is still dynamically determined according to the first parameter description, but if the downlink subframe includes subframe 0 or subframe 5, the corresponding bit overhead needs to be subtracted.

Or, in the case of adopting the bitmap, the third parameter is used by a maximum of 10 bits. In this case, the maximum time for a single occupation of the site (the signaling in the embodiment of the present invention is used by the device using the unlicensed carrier) is 10 ms, and when there are subframe 0 and subframe 5 in the subframe within the occupied duration, the station may also configure subframe 0 and subframe 5 as MBSFN subframes (in this case, subframes 0 and 5 configured as MBSFN subframes) Still send PSS/SSS/CRS, etc.). The number of bits of the specific third parameter is still determined dynamically according to the first parameter description of the number of downlink subframes.

The third parameter may also be 1-bit information, which is used to indicate whether the current subframe is an MBSFN subframe or whether the corresponding number of CRS symbols is 1 or 2, or 4 or 6.

The fourth parameter: the number of bits of the fourth parameter is the number of downlink subframes or the number of downlink subframes in the consecutive subframes indicated by the first parameter minus 1; wherein, when the last downlink subframe is a partial subframe or When the CSI-RS or CSI-IM cannot be sent, the number of bits of the fourth parameter is the number of corresponding downlink subframes minus 1, otherwise, the fourth parameter is the number of downlink subframes; and the fourth parameter indicates whether to configure by using a bitmap manner. There is CSI-RS or CSI-IM; wherein, when the bit in the fourth parameter is 1, it indicates that CSI-RS or CSI-IM is configured; when the bit in the fourth parameter is 0, it indicates that CSI is not configured. -RS or CSI-IM.

The fifth parameter: the number of bits of the fifth parameter is 1, which is used to indicate whether the current subframe is configured with CSI-RS or CSI-IM; or the number of bits of the fifth parameter is N, N≥2, which is used to indicate the current sub- The number of the CSI-RS or CSI-IM configuration information in the frame. For example, the upper layer configures the available CSI-RS/CSI-IM set, and then selects to configure the CSI-RS/CSI-IM in the fifth parameter indication subframe; for example, the upper layer configures the available CSI-RS/CSI-IM set, and then The fifth parameter indicates the number of CSI-RS/CSI-IM configuration information selected from the set in the current subframe.

The sixth parameter: the number of bits of the sixth parameter is 2, which is used to indicate the following four configurations of the current subframe: CSI-RS is configured, CSI-IM is configured, CSI-RS and CSI-IM are configured, and no Configure CSI-RS and CSI-IM. It can also be understood that one bit is set for the CSI-RS to describe whether the subframe is transmitted, and a bit is set for the CSI-IM to describe whether the subframe is transmitted.

Seventh parameter: The seventh parameter describes the CRS/CSI-RS power. Specifically, it is one or more of the power, PB value or PA value of the CRS. The seventh parameter may be configured only in a subframe within a transmission cycle timing of the DRS, and describes a CRS/CSI-RS power allocation condition in a subframe in which the DRS is configured.

Eighth parameter: The eighth parameter describes the burst number. For example, a burst number corresponding to 7 bits is used to describe the burst number.

The ninth parameter: the number of bits of the ninth parameter is 1; when the ninth parameter indicates that there is no uplink subframe in the burst, the second parameter is not configured.

The tenth parameter: when the tenth parameter indicates that the last subframe is a partial subframe, the tenth parameter is the number of downlink symbols in the last downlink subframe, or the configuration number of the DwPTS when the last subframe adopts DwPTS, or a number indicated in the candidate set set by the high layer signaling; wherein the tenth parameter is the number of downlink symbols in the last downlink subframe, and is the number of OFDM symbols directly indicating the last downlink subframe; The parameter is the configuration number of the DwPTS when the DwPTS is used in the last subframe, or the number indicated in the candidate set set by the higher layer signaling, which is an indirect indication of the number of OFDM symbols of the last downlink subframe. Specifically, the tenth parameter describes that the last subframe is a complete subframe (may also be implicitly indicated by indicating 14 symbols) or a partial subframe, and if it is a partial subframe, the number of downlink symbols in the last downlink subframe When the DwPTS is used in the last subframe, the configuration number of the DwPTS is described, or the corresponding number is indicated in the candidate set given by the high layer signaling. For example, if the upper layer gives the set of symbols of the last subframe (counted from the first symbol backwards) as {1, 3, 5, 7}, then the tenth parameter can use 2 bits to describe the four symbol numbers.

Eleventh parameter: The eleventh parameter describes whether a DRS signal exists in the subframe. Eleventh parameter It is configured only in the subframes within the transmission cycle timing of the DRS. For example, the station configures an eleventh parameter in the subframe in which the DRS is transmitted according to the DRS transmission period configured by the high layer signaling, indicating that the DRS signal exists in the subframe. The configuration pattern of the specific DRS signal is obtained by high layer signaling. The terminal attempts to receive the eleventh parameter of the physical layer in the subframe of the DRS transmission period. If the terminal receives the PDSCH in the subframe, the terminal needs to circumvent the resource sent by the DRS pattern in the subframe. Otherwise, there is no DRS transmission in the subframe. At the non-DRS cycle timing, the station may not configure the eleventh parameter, and the terminal may not receive the eleventh parameter.

Step 102: Send the signaling.

2 is a schematic flowchart of a signaling transmission method according to an embodiment of the present invention, and signaling in this example The transmission method is applied to the terminal. As shown in FIG. 2, the signaling transmission method includes the following steps:

Step 201: Receive signaling that the station configures for a subframe in a burst transmission.

The signaling of the configuration is to configure one or more of the following parameters in a partial subframe or all subframes: a first parameter, used to indicate the number of consecutive occupied subframes starting from the current subframe; The parameter is used to indicate the number of subframes after the last subframe from the downlink; the third parameter is used to indicate the number of CRS symbols in the subframe or the subframe in the burst transmission, or whether it is an MBSFN subframe; the fourth parameter The fifth parameter and the sixth parameter are used to indicate whether the CSI-RS and/or the CSI-IM are configured or specifically configured in the subframe, and the seventh parameter is used to indicate the CRS of the subframe in the subframe or in the burst transmission. /CSI-RS power; the eighth parameter is used to indicate the burst number; the ninth parameter is used to indicate whether there is an uplink subframe in the burst transmission; and the tenth parameter is used to directly or indirectly indicate the OFDM of the last downlink subframe. The number of symbols; the eleventh parameter is used to indicate whether there is a DRS in the subframe.

The specific meanings of the various parameters in this embodiment can be understood by referring to the description in the foregoing embodiments, and details are not described herein again.

Step 202: Parse the parameters configured in the partial subframe or all the subframes to obtain subframe occupation data.

In the embodiment of the present invention, when the tenth parameter is parsed in the last downlink subframe sent by the station, determining, according to the instruction of the tenth parameter, the starting position of the LBT after the first listening, and The uplink LBT is performed for uplink UL transmission.

In the embodiment of the present invention, when the sixth parameter is parsed in the downlink subframe sent by the station, determining, according to the indication of the sixth parameter, whether the current subframe is configured with CSI-RS and/or CSI- IM; obtaining configuration information of the mapping pattern of the configured CSI-RS and/or CSI-IM in the current subframe by higher layer signaling.

In the embodiment of the present invention, when the eleventh parameter is parsed in the downlink subframe sent by the station, determining whether the DRS exists in the current subframe according to the indication of the eleventh parameter; When there is a DRS and a physical downlink shared channel PDSCH is transmitted, it is determined that there is no PDSCH transmission in the resource unit RE of the DRS.

The configuration of each parameter of the embodiment of the present invention is described in detail below with reference to specific scenarios.

For Example 1, only the examples of parameter A and parameter B are used.

In the current subframe, the configuration parameter A is 0100 and the configuration parameter B is 0011. The actual occupied subframe of the station is: 4+1 subframes are downlink after the current subframe (including), and there are 3+ afterwards. 1 uplink subframe or other destination subframe. The station may also modify (to increase the number of) the number of subsequent subframes that are expected to be occupied each time the value of the parameter A is sent in the downlink subframe. This facilitates the use of fewer bits to describe more consecutive occupied subframes. For example, when the parameter A is used to describe the parameter A, when the occupation wants to claim 10 subframes, the first subframe in the station is set to a parameter A of 111, and the parameter A in the second occupied subframe is still set. As for 111, the parameter A is set to 111 in the third occupied subframe, and the parameter A is set to 110 in the fourth occupied subframe, and then sequentially decremented. Obviously, the station uses the 3bit to describe the requirement of continuously occupying 10 subframes by modifying the value of the parameter A of a part of the subframe. A similar method can be extended. For example, when the value of parameter A is only 2 bits, it can also be used.

The terminal receives the above-mentioned duration signaling in the subframe and parses it. According to the signaling convention, after the terminal parses the parameters of the parameter A and the parameter B, it is learned that there are still 5 downlink subframes after the current subframe, and then there are 4 uplinks or other The sub-frame of the destination. The terminal can use the downlink subframe to perform related measurements, such as RRM measurement, CSI measurement, etc., and can use the uplink subframe for random access.

Example 2 uses examples of parameters A, B, and C.

In the current subframe, the configuration parameter A is 0100, the configuration parameter B is 0011, and the configuration parameter C is 10101 (the number of bits in the parameter C is the number of downlink subframes described by parameter A), then the actual occupied subframe of the station is: 4+1 subframes after the start of the current subframe (including) are downlink, and there are 3+1 uplink subframes or other destination subframes, and the station occupies 4+1 downlinks. The position order of the MBSFN subframe and the non-MBSFN subframe is: an MBSFN subframe, a non-MBSFN subframe, an MBSFN subframe, a non-MBSFN subframe, and an MBSFN subframe.

The terminal receives the above-mentioned duration signaling in the subframe and parses it. According to the signaling convention, after the terminal parses the parameters of the parameter A and the parameter B, it is learned that there are still 5 downlink subframes after the current subframe, and then there are 4 uplinks or other Obtaining the number of bits and the position of the parameter C, and knowing from the parameter C that the position order of the MBSFN subframe and the non-MBSFN subframe in the five downlink subframes is: MBSFN subframe, non-MBSFN subframe, MBSFN sub-frame Frame, non-MBSFN subframe, MBSFN subframe. The terminal can use the downlink subframe to perform related measurements, such as RRM measurement, CSI measurement, etc., and can use the uplink subframe for random access.

Example 3 uses examples of parameters A, B, and D.

The station is configured to forward the MBSFN subframe configuration information in the LAA carrier of the UE through the Pcell, and may be forwarded by a point-to-point UE RRC dedicated message or by a point-to-multipoint broadcast message. For a LAA unlicensed carrier, when the site is occupied, it is determined that the subframes in the occupied period are MBSFN subframes according to the subframe timing of the corresponding Pcell. The signal/signaling is then sent in the corresponding MBSFN subframe according to the configuration requirements of the MBSFN subframe.

In the current subframe, the configuration parameter A is 0100 and the configuration parameter B is 0011. The actual occupied subframe of the station is: 4+1 subframes are downlink after the current subframe (including), and there are 3+ afterwards. 1 uplink subframe or other destination subframe, and the position order of the site occupying 4+1 downlink MBSFN subframes and non-MBSFN subframes needs to be obtained according to the parsing of the parameter D.

The terminal receives the MBSFN subframe configuration information of the LAA carrier forwarded by the Pcell, and learns the MBSFN subframe configuration pattern. Receiving the above-mentioned duration signaling in the subframe and parsing, according to the signaling convention, after the terminal parses the parameters of the parameter A and the parameter B, it is learned that there are still 5 downlink subframes after the current subframe, and then there are 4 uplink or other purposes. Sub-frame; the terminal can use the downlink subframe to perform related measurement, such as RRM measurement, CSI measurement, etc., and can use the uplink subframe for random access and the like.

Example 4 uses examples of parameters A, B, and E.

The parameter E describes that the CSI-RS or CSI-IM is configured in the subframes in the occupied downlink subframe, and the parameter E uses the bitmap mode. The configuration of the specific CSI-RS or CSI-IM is sent through the RRC message configuration of the upper layer. It is assumed that the upper layer configures parameters sent by CSI-RS or CSI-IM.

In the current subframe, the configuration parameter A is 0100 and the configuration parameter B is 0011. The actual occupied subframe of the station is: 4+1 subframes are downlink after the current subframe (including), and there are 3+ afterwards. 1 uplink subframe or other destination subframe. The configuration parameter E is 5 bits (assuming that CSI-RS or CSI-IM is also configured in the last downlink subframe), each downlink subframe corresponds to one bit, and is configured as 10101, that is, CSI in these downlink subframes. The sequence of subframes in which -RS or CSI-IM appear is: yes, no, yes, no, yes.

The terminal receives the above-mentioned duration signaling in the subframe and parses it. According to the signaling convention, after the terminal parses the parameters of the parameter A and the parameter B, it is learned that there are still 5 downlink subframes after the current subframe, and then there are 4 uplinks or other The sub-frame of the destination. The terminal further parses the parameter E, and knows that there are CSI-RS or CSI-IM in those subframes, and the terminal can use the downlink subframe to perform related measurement, such as RRM measurement, CSI measurement, etc., and can use the uplink subframe for random access, etc. .

Example 5 uses an example of parameter A, parameter B, and parameter F.

The parameter F indicates whether CSI-RS or CSI-IM is configured in the occupied downlink subframe, and the parameter F uses 1 bit. If 1 is set, it indicates that there is CSI-RS or CSI-IM, and 0 indicates that there is no CSI-RS or CSI-IM. . The configuration pattern of the specific CSI-RS or CSI-IM is sent through the RRC message configuration of the upper layer. It is assumed that the upper layer configures parameters sent by CSI-RS or CSI-IM.

In the current subframe, the configuration parameter A is 0100 and the configuration parameter B is 0011. The actual occupied subframe of the station is: 4+1 subframes are downlink after the current subframe (including), and there are 3+ afterwards. 1 uplink subframe or other destination subframe. The bit of the site configuration parameter F is 1 in the corresponding subframe with CSI-RS or CSI-IM, and the configuration bit is 0 in the corresponding CSI-RS-free. Or in the subframe of CSI-IM.

The terminal receives the above-mentioned duration signaling in the subframe and parses it. According to the signaling convention, after the terminal parses the parameters of the parameter A and the parameter B, it is learned that there are still 5 downlink subframes after the current subframe, and then there are 4 uplinks or other The sub-frame of the destination. The terminal further parses the parameter F, determines whether there is a CSI-RS or a CSI-IM in the subframe, and then uses the downlink subframe to perform related measurement according to the CSI-RS or CSI-IM configuration information according to the RRC message of the upper layer. For example, RRM measurement, CSI measurement, etc., can be performed by using an uplink subframe for random access or the like.

Embodiment 6 uses an example of parameter A, parameter B, and parameter F.

The parameter F describes the configuration pattern in which the CSI-RS or the CSI-IM is configured in the subframes in the occupied downlink subframes, and the specific CSI-RS or CSI-IM is indicated. Specifically, a CSI-RS or CSI-IM configuration pattern set is configured for the LAA carrier by using a high-layer RRC message, or the default set is optional all possible configurations (such as described in 36.211), and corresponding settings are set for each configuration. The number is described using the physical layer parameter F.

In the current subframe, the configuration parameter A is 0100 and the configuration parameter B is 0011. The actual occupied subframe of the station is: 4+1 subframes are downlink after the current subframe (including), and there are 3+ afterwards. 1 uplink subframe or other destination subframe.

The bits of the site configuration parameter F are used to describe the number of the CSI-RS or CSI-IM configuration specifically used in this subframe.

The terminal receives the above-mentioned duration signaling in the subframe and parses it. According to the signaling convention, after the terminal parses the parameters of the parameter A and the parameter B, it is learned that there are still 5 downlink subframes after the current subframe, and then there are 4 uplinks or other The sub-frame of the destination. The terminal further parses the parameter F, determines whether there is a CSI-RS or a CSI-IM in the subframe, and further determines the configuration information of the CSI-RS or the CSI-IM, and the terminal can use the downlink subframe to perform related measurement, for example, RRM measurement. For CSI measurement, etc., uplink subframes can be used for random access.

Embodiment 7 uses an example of parameter A, parameter B, and parameter G.

The parameter G indicates that there is only CSI-RS or CSI-IM in the subframe; or both CSI-RS and CSI-IM, or different CSI-RS or CSI-IM. The two states are described by using 2 bits, for example, only CSI-RS exists in the corresponding subframe of "00"; only CSI-IM exists in the corresponding subframe of "01"; CSI-RS and CSI-IM exist in the corresponding subframe of "10" ; "11" corresponds to the absence of CSI-RS or CSI-IM in the subframe. The CSI-RS and the CSI-IM adopt the existing configuration mode (periodic transmission mode), for example, the information such as the transmission period and resources of the CSI-RS and the CSI-IM are configured by the upper layer. The parameter G is used to notify whether the site triggers the configuration of the aperiodic CSI-RS or CSI-IM during the period when the LAA station occupies the unlicensed carrier, and when configured, indicates the subframe position of the aperiodic CSI-RS or CSI-IM. The configuration pattern of the aperiodic CSI-RS or CSI-IM is still executed according to the CSI-RS or CSI-IM of the high-level configuration, and only the transmission timing is randomly triggered. For example, after the site is occupied, the CSI-RS or CSI-IM is used to transmit the subframe according to the demand indication period. When the CSI-RS or CSI-IM transmission pattern is not involved in other examples, the high-level configuration pattern in this example may be combined.

In the current subframe, the configuration parameter A is 0100 and the configuration parameter B is 0011. The actual occupied subframe of the station is: 4+1 subframes are downlink after the current subframe (including), and there are 3+ afterwards. 1 uplink subframe or other destination subframe. The station configures the transmission parameter G in a subframe in which CSI-RS and/or CSI-IM need to be transmitted according to requirements.

The terminal receives the above parameters in the signaling in the subframe and parses it. According to the signaling convention, after the terminal parses the parameters of the parameter A and the parameter B, it is learned that there are still 5 downlink subframes after the current subframe, and then there are 4 uplinks. Or a sub-frame for other purposes. The terminal further parses the parameter G, determines whether there is a CSI-RS and/or a CSI-IM in the subframe, and then the terminal can use the downlink according to the pattern information of the CSI-RS and/or the CSI-IM configured by the RRC message of the upper layer. Sub-frames perform related measurements, such as RRM measurement, CSI measurement, etc., and may use uplink subframes for random access and the like.

In this manner, 2 bits or 3 bits can be used to describe the pattern of CSI-RS or CSI-IM in the subframe. For example, by using higher layer signaling, a candidate pattern is configured for the available unlicensed CSI-RS/CSI-IM. The one of the candidate patterns used in the subframe is then described by the above signaling of the physical layer. The upper layer can semi-statically update the candidate configuration pattern.

Example 8, use of physical parameter H. The parameter H describes the transmit power and/or PB value of the CRS in the subframe during occupancy (see the 36.211 protocol). After the site occupies the unlicensed carrier, the parameter H is sent in the occupied subframe, and the parameter H of each downlink burst remains unchanged during the occupation period.

Alternatively, the parameter H describes the relative increase or decrease of the CRS/CSI-RS power in the current subframe or the current burst relative to the CRS/CSI-RS power in the previous subframe or burst. This helps to reduce the overhead of the bits.

The station can use the bits in a certain DCI to describe the meaning of this parameter H. The physical meaning of the original bit in the DCI will be invalid.

Another possible transmission mode is: the station configures the power of the CRS and the value of the PB through the RRC message of the upper layer, and then dynamically changes the value of the parameter PB through the parameter H of the physical layer. Only 2 bits are needed to be sent at the physical layer. Or the upper layer configures the power of the CRS through the RRC message, and dynamically notifies the value of the PB through the physical layer parameter H.

The terminal receives the parameter H, and determines the transmission power of the CRS and the CSI-RS in the subframe according to the physical meaning of the parameter. If the terminal receives the parameter H in a certain subframe in a burst and correctly parses it, the terminal can determine the transmission power of the CRS and the CSI-RS in the burst. That is, in a DL burst, the terminal receives the parameter H at least once.

Embodiment 9, physical layer parameter I, describes the number of the burst. A corresponding number is specified for each burst, and the number is sent cyclically. For example, the burst number is 0 to 127; the 7-bit description is used and cyclically transmitted. The station sends the burst number information in each subframe occupied.

Embodiment 10, the physical layer parameter J, describes whether an uplink subframe exists in a subframe (or a burst) occupied by the station. Obviously, the definition of burst in this example includes uplink or downlink subframes. when When the parameter indicates that there is no uplink in the burst, the station can adjust the physical layer parameters to be sent. For example, the parameter B cannot be configured at this time, thereby saving bit overhead. The terminal may parse the parameter first, and then determine the remaining parameters and corresponding bits according to the indication of the parameter.

Embodiment 11, physical layer parameter K

The physical layer parameter K describes the number of downlink symbols in the last downlink subframe in the burst (or the first downlink subframe before the uplink subframe); or the configuration number of the DwPTS when the last subframe uses the DwPTS. In addition, the following method can also be used for the use of this parameter. When the length of time that the site claims to occupy (including the last downlink subframe duration) does not exceed the single maximum duration specified by the regulation or protocol, the default last downlink subframe is the complete subframe, and the site does not send the parameter K; The parameter K is sent by default when the duration of the occupation exceeds the maximum time specified by the regulation or agreement. The terminal determines the number of downlink subframes occupied by the station according to the occupied duration information sent by the station, and determines that if the occupation duration is less than or equal to the maximum occupation duration specified by the regulation or protocol, the terminal considers that the last behavior is a complete subframe, and The parameter K is not included in the received signaling.

Considering the signaling overhead and the characteristics of the channel in the last subframe, for example, the control channel occupies the first 3 symbols. The number of possible symbols for the last downlink subframe is recommended. One case is {3,6,8,9,10,11,12,14} or {3,6,7,9,10,11,12,14} Or {6,9,10,11,12,13,14}, using 3bit for description. One case is {1~14}, using a 4-bit description.

The data transmission in the last downlink subframe of the station is sent in the manner of a complete subframe, and redundant data is transmitted for some idle resources.

Example 12, use of parameter L.

The physical layer parameter L describes whether a DRS signal exists in the subframe. This parameter is only configured to be sent in a subframe within the timing of the DRS period configured by the station. For example, the station configures the parameter L in the subframe in which the DRS is sent according to the DRS transmission period configured by the high layer signaling, indicating that the subframe exists. DRS signal. The configuration pattern of the specific DRS signal is obtained by high layer signaling. The terminal attempts to receive the physical layer parameter L in a subframe of the DRS transmission cycle timing. If the terminal receives the PDSCH in the subframe, the terminal needs to circumvent the resource transmitted by the DRS pattern in the subframe. Otherwise, there is no DRS transmission in the subframe. At the non-DRS cycle timing, the sender may not send this parameter configuration. The terminal may also not receive the parameter.

The UE attempts to receive the parameter of the DRS in the subframe in the subframe of the LAA downlink burst. If the parameter is received, then according to the indication of the parameter, it is determined whether the DRS is configured and sent in the subframe, if the subframe is configured. When the DRS is transmitted and the PDSCH is transmitted, the UE considers that there is no PDSCH transmission in the RE of the DRS.

Embodiment 13 describes a parameter transmission for the above signaling, DCI mode.

The DCI format is the existing downlink control information, and the number of bits carried is generally about 20 bits. The independent parameters or combined parameters for the above signaling may be sent by DCI. For the case where the number of bits of signaling is less than or equal to the number of existing DCI bits, the existing DCI format is used to redefine the meaning of the bits therein to the corresponding parameters in the above signaling, and the invalid padding bits are used for the insufficient number of bits. Occupied. It can be transmitted in one PDCCH by using existing DCI coding and data mapping.

Or design a new DCI format, use the bits in it to describe the parameters in the above signaling, and then transmit in one PDCCH by using the existing DCI coding and mapping manner.

At present, the resource location of the DCI is also obtained by blind detection, which is not conducive to the reception of the signaling. In particular, the signaling will be frequently sent in most of the subframes (or each subframe) in the burst transmitted by the base station, if still used. The above-mentioned existing blind detection resource location and blind decoding DCI mode are very wasteful for the power consumption of the UE. To overcome the above problem, the following method is given for the resource location determination of the DCI.

The fixed CCE location (or the RE corresponding to the fixed CCE) is used to send the above signaling. Preferably, the fixed (the sender and the receiver agree in advance) are CCE numbers 0 to 3 or 0 to 7. (The CCE number to the corresponding RE resource mapping is known to the UE, so only the CCE number is required, and the UE can obtain the corresponding RE resource). The site reserves the above fixed CCE. The station transmits in the PDCCH each time in these fixed CCEs using a predetermined coded modulation and mapping scheme. The terminal receives only in the above fixed CCE number in the subframe and decodes according to the inverse process of the agreed code modulation mode. This method is equivalent to defining a new physical channel, which is always located in the first 1 or 2 or 3 or 4 symbols in the subframe, and the first 4 or the first 8 CCEs correspond to the RE. The physical channel is used to send the above signaling. Obviously, the coding and modulation methods used in signaling can follow the debugging code of the existing DCI mode. The channel carrying the fixed physical resource carries the foregoing signaling, which can prevent the UE from blindly checking physical resources and blindly checking the corresponding DCI in the resource, thereby greatly simplifying the complexity of UE reception.

The specific terminal decoding process for signaling refers to other embodiments described above.

Embodiment 14, using PHICH resources or resources similar to those obtained by PHICH resource definition

The station uses the fixed RE location to send the above signaling, and the specific RE location is defined as (which can be flexibly matched according to the number of bits of signaling): the RE resource defined for the PHICH is used. For example, suppose that the standard fixed fixed signaling uses four CCEs of coded modulation to transmit, then the corresponding needs 36 (36 REs per CCE) * 4 RE resources. In the prior art, the HARQ acknowledgment information (1 bit) transmitted in one PHICH channel is repeated 3 times, and then spread using BPSK modulation and using an orthogonal sequence with a length of 4 (extended CP, length 2). After scrambling using the cell-specific scrambling sequence, 12 scrambled symbols (modulation) are obtained. The base station needs to confirm 12 RE resources according to the agreed rules (see 36.211 protocol), and map the 12 scrambled modulation symbols to the corresponding 12 REs according to the agreed mapping rules (see 36.211 protocol). Thereby completing the transmission.

In this embodiment, in order to transmit the parameters in the signaling formed by the DCI mode in Embodiment 14, the base station determines the corresponding RE resource in the following manner. The base station and the terminal agree to use several (for example) For example, 12, which may be other values, which may determine the number of data to be transmitted according to the above signaling code) PHICH channel group, each group of PHICH resources contains 12 REs (corresponding to the existing 12 modulation symbols) RE), thus obtaining 12*12 REs for parameter bit transmission in the above signaling.

It is assumed that the parameter bits in the above signaling are composed according to the foregoing manner of the present application, and 22 bits are assumed, and the 22-bit DCI code modulation mode is processed to obtain the final transmission data, and then the transmission data is mapped to the obtained 12*12 REs. Sent in.

For the definition of the PHICH channel, the existing method is adopted, but the specific definition parameters are required to be agreed in advance by the base station and the terminal, so that the resource location of the PHICH defined by the sender and the terminal is understood to be the same.

Embodiment 15 describes a manner of fixing resources for parameter transmission of the above signaling.

The base station sets a new physical channel to carry in the first 1 or 2/3 symbols of the subframe. The new physical channel satisfies: the introduction of a new fixed location RE is used for the transmission of the above signaling, or the transmitting end/terminal can push to a specific fixed RE resource location according to the agreed known information. The above signaling is transmitted in a new physical channel. The new physical channel is determined as follows:

For example, CCEs numbered 0 to 3 are fixed in the control domain of the subframe for the above-mentioned signaling parameter transmission.

For example, in the first symbol of the subframe, the RE of the PCFICH resource is removed, and/or the RE of the PDCCH common search area is removed, and/or the RE of the CRS is removed, and the RE is determined in the remaining REs to transmit the above signaling. The determined number of REs is determined according to the coding modulation scheme of the above signaling convention. The REs (subcarriers) that can be used are calculated in the following manner according to a given frequency domain period (in units of subcarriers) and the starting subcarrier number.

N (subcarrier number) mod frequency domain period = starting subcarrier number. After a given period value and a starting subcarrier number, the subcarrier corresponding to the N satisfying the equation is the new physical channel.

For example, there are 1200 subcarriers in the bandwidth of 20 MHz. In this case, the period can be defined as 6, and the starting subcarrier number is 0. Then there are 200 subcarriers corresponding to the N value satisfying the equation, taking the M RE (M is the total number of bits according to the parameters of the above signaling, the number of REs corresponding to the data to be transmitted obtained after the modulation and coding process, and once the number of bits, modulation, and coding are determined, the M value is uniquely determined) is used for the above-mentioned letter. Let the transmission (such as the first M REs selected or the M Ms in the middle). When the RE overlaps with the existing PCFICH, CRS, or RE of the PDCCH common search area, the RE is rejected from the RE that transmits the above signaling.

The above manner may also be changed to the following usage mode, and the subcarrier corresponding to the above N is defined as the starting subcarrier for transmitting the signaling. Then, in the description of the continuous V subcarriers for transmitting the above signaling, the subcarriers numbered N, N+1, N+2....N+V-1 are subcarriers transmitting the above signaling (in one OFDM symbol) The neutron carrier corresponds to the RE one by one).

Example 16

When the station transmits the uplink data by using the unlicensed carrier, the station transmits the uplink grant information through the DCI information in the PDCCH in the authorized carrier (ie, the Pcell carrier), and the UE uses the unlicensed carrier. The above signaling configuration is carried in the above DCI in the authorized carrier.

Or the above signaling is sent in other predetermined REs of the licensed carrier.

That is to say, the above signaling can be sent by using the bearer mode in the foregoing bearer mode.

Example 17

For parameters A and B, the following methods can also be used for a unified description.

For example, it is stipulated that the maximum duration of the station is 10 (10 is only one example) subframes. The site and the receiving end agree to use a 10-bit bitmap description. For example, when the corresponding bit is set to 1, the subframe is downlink, and 0 is set. This subframe is uplink.

Example 18

In the case of using the bitmap, the third parameter is used by a maximum of 8 bits (the cost of the following two subframes has been subtracted), and the site is specified at this time (the signaling in the embodiment of the present invention is unauthorized use). The device of the carrier can be used. The maximum duration of a single occupation is 10 ms, and when there are subframe 0 and subframe 5 in the subframe within the occupied duration, the station does not configure subframe 0 and subframe 5 as MBSFN subframes. The number of bits of the specific third parameter is still dynamically determined according to the first parameter description, but if the downlink subframe includes subframe 0 or subframe 5, the corresponding bit overhead needs to be subtracted. For example, the subframes occupied by the station are subframes 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9, respectively, assuming no uplink subframes; at this time, 8 bits of the bitmap correspond to subframes 1 2, 3, 4, 6, 7, 8, and 9; the receiving end needs to determine and eliminate the subframe 0 and the subframe 5 in the occupied subframe, and then determine the correspondence between the bitmap signaling and the remaining subframes.

Or, in the case of adopting the bitmap, the third parameter is used by a maximum of 11 bits. In this case, the maximum time for a single time occupied by the specified site (the signaling in the embodiment of the present invention is used by the device using the unlicensed carrier) is 13 ms, and when there are subframe 0 and subframe 5 in the subframe within the occupied duration, the station does not configure subframe 0 and subframe 5 as MBSFN subframes. The number of bits of the specific third parameter is still dynamically determined according to the first parameter description, but if the downlink subframe includes subframe 0 or subframe 5, the corresponding bit overhead needs to be subtracted. For example, the subframes occupied by the station are subframes 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 1, 2, and 3, respectively, assuming no uplink subframes; The bit corresponds to the subframes 1, 2, 3, 4, 6, 7, 8, 9, 1, 2, and 3; the receiving end needs to determine and eliminate the subframe 0 and the subframe 5 in the occupied subframe, and then determine the bitmap. Correspondence between signaling and remaining subframes.

Or, in the case of adopting the bitmap, the third parameter is used by a maximum of 10 bits, and the specified site (the signaling in all the embodiments of the present invention is used by the device using the unlicensed carrier) is the largest single occupancy. The duration is 10 ms, and when there are subframe 0 and subframe 5 in the subframe within the occupied duration, the station may also configure subframe 0 and subframe 5 as MBSFN subframes (in this case, subframe 0 configured as an MBSFN subframe) 5 still sends PSS/SSS/CRS, etc.). The number of bits of the specific third parameter is still determined dynamically according to the first parameter description of the number of downlink subframes. For example, the subframes occupied by the station are subframes 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9, respectively, assuming no uplink subframes; At this time, the 10 bits of the bitmap correspond to the subframes 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. In this case, two potential processing methods can be adopted for the subframe 0 and the subframe 5: 1. PSS/SSS/CRS is not sent in subframes 0 and 5. Mode 2, subframe 0 and subframe 5 are MBSFN subframes, but the MBSFN subframes can transmit PRS/SSS in Rel-12; The receiving end agrees in advance which specific processing method is adopted. The receiving end needs to determine whether to eliminate the subframe 0 and the subframe 5 in the occupied subframe according to the agreed processing manner, and then determine the correspondence between the bitmap signaling and the remaining subframes.

The foregoing embodiments may be used in combination, for example, using different embodiments to transmit some of the above parameters, such as a PHICH way to send partial parameters, a DCI mode to send partial parameters, and the like.
