Method, device and system for sending and receiving scheduling user data information

[0133]Example one:

[0134] In the 3GPP E-UTRA system, there are usually no more than 8 uplink control signaling units reserved for PUCCH. In most cases, x (the difference between the start resource block addresses allocated to user data and the end The value of the difference between the resource block addresses) will not exceed the range of [-3, 3], that is, there are 7 values, so 3 bits of the PUCCH RB allocation field are sufficient. As a compromise between overhead and performance, it is also possible to limit the value of x not to exceed the range of [-1, 1]. In this case, 2 bits of the PUCCH RB allocation field are sufficient.

[0135] In the example, suppose that the PUCCH RB field is 3 bits, and the corresponding relationship between the value of these 3 bits and the value of x is shown in Table 1 below

[0136] PUCCH RB allocation field value 000 001 010 011 100 101 110 111 x value 0 1 -1 2 -2 3 -3 Reserved

[0137] Table 1

[0138] Assume that PUCCH is reserved such as Figure 4 The four uplink control signaling resource units shown. In a certain uplink subframe, Figure 4 There is no user sending uplink control signaling on the two middle black uplink control signaling resource units. The base station wants to allocate the following uplink time-frequency resources to user equipment UE0 through the physical layer uplink scheduling authorization command: VRBs with addresses 1 and 2 are in the first half RB resources of the subframe, VRB resources with addresses 3 and 4, that is, the starting resource block address of the first half of the subframe RBIndex start first = 1 , End resource block address of the first half of the subframe RBIndex end first = 4 , Starting resource block address of the second half of the subframe RBIndex start sec ond = 3 And the end resource block address of the second half of the subframe RBIndex end sec ond = 4 . Then the base station configures the standard starting resource block address in the RB allocation field RBIndex start = min { RBIndex start first , RBIndex start sec ond } = 1 , Number of standard continuous resource blocks RBLength = max { RBIndex end first , RBIndex end sec ond } - min { RBIndex start first , RBIndex start sec ond } + 1 = 4 (The number of addresses from the standard start resource block address to the standard end resource block address). Standard end resource block address RBIndex end = max { RBIndex end first , RBIndex end sec ond } = 4 . The VRB with address 1 contains RB resources reserved for the upper sideband of PUCCH, and the VRB with address 4 does not contain RB resources reserved for the lower sideband of PUCCH, so the difference is x = RBIndex start first - RBIndex start sec ond = - 2 , According to Table 1, the PUCCH RB allocation field should be configured as 100.

[0139] After the user equipment UE0 receives the physical layer uplink scheduling authorization command issued by the base station, it analyzes the RBIndex through the RB allocation field start = 1 and RBLength = 4, and x = -2 is parsed through the 100 of the PUCCH RB allocation field, then RBIndex end =RBIndex start +RBLength-1=4. Since the VRB with address 1 contains RB resources reserved for the upper sideband of PUCCH, and the VRB with address 4 does not contain reserved RB resources for the lower sideband of PUCCH, and x<0, it will be resolved RBIndex start first = RBIndex start = 1 , RBIndex end first = RBIndex end = 4 , RBIndex start sec ond = RBIndex start - x = 3 with RBIndex end sec ond = RBIndex end = 4 , Therefore, it is learned that the uplink data packets occupy the following time-frequency resources: the RB resources of the VRB with addresses 1 and 2 in the first half subframe, and the VRB resources with addresses 3 and 4. The user equipment UE0 will send uplink data packets on the above-mentioned time-frequency resources, and perform rate matching at the VRBs with addresses 1 and 2 through a specific rate matching module.

[0140] Assume that PUCCH is reserved such as Figure 4 The four uplink control signaling resource units shown. In a certain uplink subframe, Figure 4 There is no user sending uplink control signaling on the two middle black uplink control signaling resource units. The base station wants to allocate the following uplink time-frequency resources to the user equipment UE0 through the physical layer uplink scheduling authorization command: VRB addresses 24 and 25 are behind Half-subframe RB resources, VRB resources with addresses 22 and 23, that is, the start resource block address of the first half of the subframe is 22, the end resource block address of the first half of the subframe is 23, and the start resource of the second half of the subframe The block address 22 and the end resource block address 25 of the second half of the subframe. Then the base station configures the standard starting resource block address as 22 and the standard number of consecutive resource blocks as 4 (the number of addresses from the standard starting resource block address to the standard ending resource block address) in the RB allocation field. The standard end resource block address is the end resource block address 23 of the first half of the subframe and the end resource block address 25 of the second half of the subframe, the end resource block address 25 of the second half of the subframe. The VRB with an address of 25 contains reserved RB resources for the lower side of the PUCCH, and the VRB with an address of 22 does not include RB resources reserved for the upper side of the PUCCH, so the difference is the end resource block address 23 of the first half of the subframe and the end of the second half of the subframe. The difference between the end resource block address 25 is -2, and the PUCCH RB allocation field should be configured as 100 according to Table 1.

[0141] After user equipment UE0 receives the physical layer uplink scheduling authorization command issued by the base station, it parses through the RB allocation field to find that the standard starting resource block address is 22 and the number of standard continuous resource blocks is 4, and it is resolved by 100 in the PUCCH RB allocation field If the travel value is -2, the standard end resource block address is 4 addresses up to 22, which is 25. Since the VRB with an address of 25 contains reserved RB resources on the upper side of the PUCCH, and the VRB with an address of 22 contains no reserved RB resources on the lower side of the PUCCH, and the difference is less than zero, the starting resource block address of the first half of the subframe will be parsed It is 22. The end resource block address of the first half of the subframe 23, the start resource block address of the second half of the subframe 22, and the end resource block address of the second half of the subframe 25, so as to know that its uplink data packet will occupy the following time-frequency resources : VRB resources with addresses 24 and 25 in the second half of the subframe, and VRB resources with addresses 22 and 23. The user equipment UE0 will send uplink data packets on the above-mentioned time-frequency resources, and perform rate matching through a specific rate matching module at the VRB addresses 24 and 25.

[0142] In the above example, the state where the value of the PUCCH RB allocation field is 111 is not used. When an odd number of uplink control signaling resource units are reserved for PUCCH, if the last uplink control signaling resource unit occupies the first half and the second half of the subframe at the upper and lower sidebands, the state 111 can also be used to indicate x =-4; if the last uplink control signaling resource unit occupies the second half and the first half of the subframe at the upper and lower sidebands, the state 111 can also be used to indicate x=4. Since both the user equipment and the base station know which pair of RB resources of the upper and lower sidebands are occupied by the last uplink control signaling resource unit at this time, the state 111 can clearly indicate that x=-4 or x=4, which will not be confused. .

[0143] Through the technical solution of the first embodiment, the present invention first selects a group of the left resource block group and the right resource block group allocated for user data, and uses its channel resource start address and the number of continuously occupied resource blocks as the reference standard, and then The position mark is used to indicate the position difference of another resource block group with respect to the reference standard, thereby determining the allocation of the entire user data, and clarifying which part of the RB resources reserved for PUCCH can be used by the user data, so that it is clear that the user data can be used Which part of the RB resources are reserved for the purpose of PUCCH, and it occupies fewer bits, only three.

[0144] The second physical layer uplink control channel resource block allocation field value method:

[0145] The physical layer uplink control channel resource block allocation field indicates the user resource allocation mode.

[0146] The user resource allocation mode is one of the following allocation modes,

[0147] Mode 1: When a certain virtual resource block allocated to user data includes the resource block reserved for the physical layer uplink control channel in the upper sideband, the resource allocated to the user equipment is specifically the certain virtual resource block. The resource block in the first half of the subframe.

[0148] When a certain virtual resource block allocated to user data includes the resource block reserved for the physical layer uplink control channel in the lower sideband, the resource allocated to the user equipment is specifically the certain virtual resource block after the subframe Half of the resource block.

[0149] When a certain virtual resource block allocated to user data does not include the resource block reserved for the physical layer uplink control channel, the resource allocated to the user equipment is specifically the certain virtual resource block in the first half of the subframe And the second half of the resource block.

[0150] Mode 2: When a certain virtual resource block allocated to user data includes the resource block reserved for the physical layer uplink control channel in the upper sideband, the resource allocated to the user equipment is specifically that the certain virtual resource block is Resource block in the second half of the subframe.

[0151] When a certain virtual resource block allocated to user data includes the resource block reserved for the physical layer uplink control channel in the lower sideband, the resource allocated to the user equipment is specifically the certain virtual resource block after the subframe Half of the resource block.

[0152] When a certain virtual resource block allocated to user data does not include the resource block reserved for the physical layer uplink control channel, the resource allocated to the user equipment is specifically the certain virtual resource block in the first half of the subframe And the second half of the resource block.

[0153] Mode 3: For a certain virtual resource block allocated to user data, the resources allocated to the user equipment are specifically the resource blocks of the certain virtual resource block in the first half and the second half of the subframe.

[0154] Corresponding to the second physical layer uplink control channel resource block allocation field value method, the physical layer uplink control channel resource block allocation field judgment method two is specifically as follows:

[0155] The physical layer uplink control channel resource block allocation field indicates the user resource allocation mode.

[0156] Its analysis mode is one of the following analysis modes,

[0157] Mode 1: When a certain virtual resource block allocated to user data includes the resource block reserved for the physical layer uplink control channel in the upper sideband, the resource allocated to the user equipment is specifically the certain virtual resource block. The resource block in the first half of the subframe.

[0158] When a certain virtual resource block allocated to user data includes the resource block reserved for the physical layer uplink control channel in the lower sideband, the resource allocated to the user equipment is specifically the certain virtual resource block after the subframe Half of the resource block.

[0159] When a certain virtual resource block allocated to user data does not include the resource block reserved for the physical layer uplink control channel, the resource allocated to the user equipment is specifically the certain virtual resource block in the first half of the subframe And the second half of the resource block.

[0160] Mode 2: When a certain virtual resource block allocated to user data includes the resource block reserved for the physical layer uplink control channel in the upper sideband, the resource allocated to the user equipment is specifically the certain virtual resource block. Resource block in the second half of the subframe.

[0161] When a certain virtual resource block allocated to user data includes the resource block reserved for the physical layer uplink control channel in the lower sideband, the resource allocated to the user equipment is specifically the certain virtual resource block after the subframe Half of the resource block.

[0162] When a certain virtual resource block allocated to user data does not include the resource block reserved for the physical layer uplink control channel, the resource allocated to the user equipment is specifically the certain virtual resource block in the first half of the subframe And the second half of the resource block.

[0163] Mode 3: For a certain virtual resource block allocated to user data, the resources allocated to the user equipment are specifically the resource blocks of the certain virtual resource block in the first half and the second half of the subframe.

[0165] Embodiment two:

[0166] It is assumed that user data can only occupy the RB resources reserved for PUCCH in the following three modes. Mode 1: For all VRBs that contain PUCCH upper sideband reserved RB resources allocated to user data, user equipment can only use the RB resources corresponding to the VRB in the first half subframe; for all PUCCH lower sidebands allocated to user data, reserve RB resources Resource VRB, the user equipment can only use the RB resources corresponding to the VRB in the second half subframe. Mode 2: For all VRBs that contain PUCCH upper sideband reserved RB resources allocated to user data, user equipment can only use the RB resources corresponding to the VRB in the second half subframe; for all PUCCH lower sidebands allocated to user data, reserved For the VRB of the RB resource, the user equipment can only use the RB resource corresponding to the VRB in the first half subframe. Mode 3: For all VRBs containing PUCCH upper sideband or lower sideband reserved RB resources allocated to user data, the user equipment can use the RB resources of the corresponding VRB in the entire subframe. Then the PUCCH RB can use 2 bits to represent the above three modes, as shown in Table 2 below. After receiving the physical layer uplink scheduling authorization command issued by the base station, the user equipment first analyzes the VRB resources allocated to user data through the RB allocation field, and then parses out the VRB resources that contain PUCCH reserved RB resources through the PUCCH RB allocation field For the specific occupied RB resources, the specific time-frequency resource information allocated to the user data is obtained.

[0167] PUCCH RB allocation field value 00 01 10 11 Corresponding mode Mode one Mode two Mode Three Reserved

[0168] Table 2

[0169] Through the technical solution of the second embodiment, the present invention presets several modes for allocating uplink control channels for user data, and translates these modes into binary codes during application, and sends them to the user equipment through the position mark to clarify the user data Which part of the RB resources of the uplink control channel can be used is clearly defined, the coding on the base station side and the user equipment side is relatively simple, and it takes up fewer bits.

[0170] As mentioned above, in order to support the allocation of user data when no user sends uplink control signaling on the uplink control signaling resource unit reserved for PUCCH, the PUCCH RB allocation field should be added to the physical layer uplink scheduling authorization command to further clarify Which part of the RB resources reserved for PUCCH is occupied by user data. However, directly increasing the PUCCH RB allocation field will increase the total number of bits of the physical layer uplink scheduling authorization command and reduce the coverage radius of the physical layer uplink scheduling authorization command. Considering that the probability of occurrence of RB resources reserved for PUCCH for user data allocation is low, some restrictions can be placed on the scenarios that can occur, so that the PUCCH RB allocation field and other signaling fields share bits in the physical layer uplink scheduling authorization command Field to avoid increasing the total number of bits of the physical layer uplink scheduling authorization command. Since the user equipment can learn whether there are VRB and PUCCH reserved RB resources among the allocated data resources through the RB allocation field in the physical layer uplink scheduling authorization command, it knows how to parse the shared bit field without causing confusion.

[0171] In the 3GPP E-UTRA system, the physical layer uplink scheduling authorization command contains a demodulation pilot cyclic shift field with a size of 3 bits, which is used to indicate the solution of the MIMO user in the case of uplink MIMO (multiple input multiple output system). The cyclic shift of the orthogonal sequence used to adjust the pilot. The demodulation pilot cyclic shift field is useless and unnecessary for non-MIMO users. Therefore, it can be restricted that only uplink non-MIMO user equipment can be allocated RB resources reserved for PUCCH, so that 3 The 1-bit PUCCH RB allocation field and the above-mentioned demodulation pilot cyclic shift field share the 3-bit signaling field in the physical layer uplink scheduling grant command. After receiving the physical layer uplink scheduling authorization command issued by the base station, the user equipment first analyzes the VRB resources allocated to user data through the RB allocation field. If the allocated VRB resources contain PUCCH reserved RB resources, the signaling will be shared The field is parsed according to the PUCCH RB allocation field, otherwise the shared signaling field is interpreted according to the demodulation pilot cyclic shift field.

[0172] In the 3GPP E-UTRA system, the physical layer uplink scheduling authorization command contains a retransmission sequence number field with a size of 2-3 bits, which is used to indicate to the user equipment whether this data packet transmission is a new data packet transmission and HARQ redundancy version. Considering that the current baseline of 3GPP E-UTRA system uplink data transmission is a synchronous non-adaptive HARQ process, the physical layer uplink scheduling authorization command is not required during retransmission. If the user equipment allocated with PUCCH reserved RB resources can only transmit new data, and use a predefined HARQ redundancy version, then the 2-3 bit PUCCH RB allocation field can be combined with the above re- The transmission sequence number field shares the 2-3 bit signaling field in the physical layer uplink scheduling authorization command. After receiving the physical layer uplink scheduling authorization command issued by the base station, the user equipment first analyzes the VRB resources allocated to user data through the RB allocation field. If the allocated VRB resources contain PUCCH reserved RB resources, the signaling will be shared The field is parsed according to the PUCCH RB allocation field, otherwise the shared signaling field is interpreted according to the retransmission sequence number field.

[0173] Of course, in addition to the PUCCH RB allocation field in the above two examples that completely share the bit field with other signaling fields, the bit field can also be partially shared with other signaling fields. For example, in the 3GPPE-UTRA system, the physical layer uplink scheduling authorization command contains a transmission format indication field with a size of about 6 bits, which is used to indicate to the user equipment the transmission format used for data packet transmission, such as modulation and coding methods, Or modulation method and transport block size. If the user equipment allocated with PUCCH reserved RB resources can only use 8 transmission formats for data transmission, then the above transmission format indication field can be compressed from 6 bits to 3 bits at this time. At the same time, the remaining 3 bits are used as the PUCCH RB allocation field. After receiving the physical layer uplink scheduling authorization command issued by the base station, the user equipment first analyzes the VRB resources allocated to the user data through the RB allocation field. If the allocated VRB resources contain PUCCH reserved RB resources, 6 bits are shared The signaling field is parsed according to the 3-bit transmission format indication field and the 3-bit PUCCH RB allocation field, otherwise the shared signaling field is interpreted according to the 6-bit transmission format indication field.

[0174] In addition, such as Figure 7 As shown, the embodiment of the present invention also provides a device for sending information for scheduling user data, including:

[0190] As another preferred solution, the resource block analysis module is:

[0191] User resource allocation mode analysis module: used to parse the physical layer uplink control channel resource block allocation field into a user resource allocation mode.

[0192] Such as Picture 9 As shown, the embodiment of the present invention also provides a system for sending and receiving information for scheduling user data, including:

[0193] Base station: used to issue broadcast information and physical layer uplink scheduling authorization commands.

[0194] The broadcast information carries resource block address information reserved for the physical layer uplink control channel in the uplink system bandwidth.

The number of consecutive resource blocks is indicated.

[0196] The physical layer uplink scheduling grant command includes a physical layer uplink control channel resource block allocation field, when at least a part of the virtual resource block allocated to the user equipment in the uplink system bandwidth is the physical layer uplink control channel preset When reserved resource blocks, the physical layer uplink control channel resource block allocation field carries the resource block location information of the user data allocated to the user equipment in the uplink system bandwidth.

[0197] User equipment: used to receive broadcast information and physical layer uplink scheduling authorization commands.

[0198] The address information of the resource block reserved for the physical layer uplink control channel in the uplink system bandwidth is parsed from the broadcast information.

[0199]From the resource block resource allocation field included in the physical layer uplink scheduling authorization command, the virtual resource block address allocated to the user equipment in the uplink system bandwidth is parsed through the standard starting resource block address and the standard continuous resource block number.

To clarify which part of the time domain and frequency domain resources in the resources reserved for PUCCH can be used by user data, which affects the normal transmission of user data, and improves the security of system operation.
