Further, the network equipment can send wave beam to terminal and indicate information by high-level signaling, such as radio resource control information in above-mentioned steps.In order to reduce the expense of signaling, the wave beam of the terminal side of the pairing, which can be, to be semi-statically configured.

As it can be seen that implement the embodiment of the present application, so that the wave beam pairing that the multi-antenna transmission mode that data transmission uses is exported based on wave beam management process, the array gain and data for improving antenna pass through the pairing multi-beam transmission that wave beam management process determines, Improve the reliability of data transmission.In addition, the transmission of Physical layer control information and physical layer data information shares the wave beam pairing of the same wave beam management process output, Physical layer control information and physical layer data information is avoided respectively to use the wave beam pairing of a wave beam management process output, data transmission delay is reduced, and ensure that the reliability of Physical layer control information transmission is greater than the reliability of physical layer data information transmission.

Embodiment two:

Identical wave beam based on the output of same wave beam management process described in embodiment one matches set, step S201 can be with are as follows: terminal each OFDM modulation (Orthogonal Frequency Division Multiplexing in the first region, OFDM) on symbol, circulation sends Physical layer control information using the wave beam for the terminal side matched in wave beam pairing set.Step S202 can be with are as follows: wave beam of the terminal based on the terminal side in wave beam pairing set in second area, the wave beam for the terminal side that the transmission number of plies is M is generated to send physical layer data information, M is the positive integer of the number of the wave beam of the terminal side greater than zero and less than or equal to pairing.

Wherein, which can be the region for occupying the uplink time/frequency source block transmission Physical layer control information for being scheduled to terminal, which can take up the region for being scheduled to the uplink time/frequency source block transmission physical layer data information of terminal.Optionally, the uplink time/frequency source block for being scheduled to terminal that the first area and the second area occupy can be same and the continuous time/frequency source block in time domain and frequency domain, the first area and the second area are in the uplink time/frequency source block, time domain is identical, frequency domain is different, and adjacent on frequency domain in the first area and the second area.

Specifically, the network equipment can pass through high-level signaling when terminal is in connected state, for example radio resource control information notifies the configuration of the terminal waveform, alternatively, the network equipment can notify the configuration of the terminal waveform by the message2 in random access procedure when terminal is in Idle state.If the network equipment notifies that the waveform of terminal is cyclic prefix orthogonal frequency division multiplexing (cyclic prefixed orthogonal frequency divided multiplexing, CP-OFDM) waveform, the network equipment can send the first configuration information to terminal, first configuration information can indicate that first area occupies the subband width for being scheduled to the uplink time/frequency source block of terminal, and terminal receives first configuration information.First area can be the uplink time/frequency source block edge, and subband width is the region of the subband width of first configuration information instruction, which can be the region in addition to the first area in the uplink time/frequency source block；Alternatively, first area can be the uplink time/frequency source block center position, subband width is the region of the subband width of first configuration information instruction, and second area can be the region etc. in addition to the first area in the uplink time/frequency source block.At this point, the first area and the second area are in the uplink time/frequency source block, time domain is identical, frequency domain is different, and adjacent on frequency domain in the first area and the second area.

Such as, a kind of schematic diagram of first area and second area shown in Fig. 3 A, whole region shown in Fig. 3 A is the uplink time/frequency source block that the network equipment is terminal scheduling, if it is delta_1 that first configuration information instruction first area that terminal receives, which occupies the subband width of the time/frequency source block, the unit of delta_1 is Physical Resource Block (physical resource block, PRB), as shown in Fig. 3 A left hand view, the first area can be the region that the uplink time/frequency source block edge subband width is delta_1, second area is the region in addition to first area of the uplink time/frequency source block；Alternatively, first area can be the region that the center position subband width of the uplink time/frequency source block is delta_1 as shown in Fig. 3 A right part of flg, second area is the region in addition to the first area of the uplink time/frequency source block.

Further, the network equipment can be by high-level signaling, for example radio resource control information sends first configuration information to terminal, and the first area and second area can be semi-statically configured by high-level signaling, reduce Physical layer control information and The propagation delay time of physical layer data information.

In each OFDM symbol in the first area, it can be according to successively sequence or other sequences, such as it is random etc., loop configuration has the wave beam of the terminal side of a pairing in above-mentioned wave beam pairing set, and terminal can send Physical layer control information using the wave beam in configuration in the first region each OFDM symbol.

Further, Physical layer control information can be sent with fixed rate.

Such as, the schematic diagram of another first area and second area shown in Fig. 3 B, the OFDM symbol of the first area from left to right: symbol 1 to symbol 14, the wave beam configured with the terminal side matched in above-mentioned wave beam pairing set: wave beam 1 can be circuited sequentially, wave beam 3 and wave beam 8, i.e. symbol 1 is configured with wave beam 1, symbol 2 configures wave beam 3, symbol 3 is configured with wave beam 8, symbol 4 is configured with wave beam 1, symbol 5 is configured with wave beam 3, symbol 6 is configured with wave beam 8, symbol 7 is configured with wave beam 1, symbol 8 configures wave beam 3, symbol 9 is configured with wave beam 8, symbol 10 is configured with wave beam 1, symbol 11 configures wave beam 3, symbol 12 is configured with wave beam 8, symbol 13 is configured with wave beam 1, symbol 14 configures wave beam 3.

Or, in each OFDM symbol in the first area, there can be the wave beam for the terminal side matched in above-mentioned wave beam pairing set according to circulation pattern loop configuration, terminal can send Physical layer control information using the wave beam in configuration in the first region each OFDM symbol, wherein, the circulation pattern can be such as following formula, x is radio frame number, and y is that the identity recognition number ID, z of terminal are symbol serial number, k is the number of wave beam, and BeamID is the serial number of wave beam.Analysis based on embodiment one is it is found that the serial number of the wave beam is in fact the serial number of downstream measurement reference signal.

F (x, y, z) ∈ { BeamID }

One specific embodiment of above-mentioned f (x, y, z) is:

F (x, y, z)=mod (Ax+By+Cz+D, k)+1

The integer that wherein { A, B, C, D } is and x, y, z are unrelated.Such as, assuming that A=3, B=2, C=1, D=0, radio frame number x=3 then on the first area shown in Fig. 3 B, if identity recognition number part identifier y=1 of terminal, on the first area, then in the first area in OFDM symbol 1 (z=1), according to above-mentioned circulation pattern formula, the wave beam that can be configured with is wave beam 2, it may be assumed that

F (x, y, z)=mod (3x+2y+z, k)+1=1

In the OFDM symbol 2 (z=2) in the first area, the wave beam of configuration is wave beam 2, it may be assumed that

F (x, y, z)=mod (3x+2y+z, k)+1=2

In the OFDM symbol 3 (z=3) in the first area, the wave beam of configuration is wave beam 2, it may be assumed that

F (x, y, z)=mod (3x+2y+z, k)+1=3

Etc..

As it can be seen that first area uses transmission diversity technology, the quality of Physical layer control information transmission is improved.

In the second area, the first modulation and coding parameter (Modulation and Coding Scheme that transmission number of plies M can be provided based on the network equipment, MCS), the first order instruction (Rank Indication, RI) and one or more confirms (Acknowledgement, ACK) or non-determined (Non-Acknowledgement, NACK) information determine.

Wherein, the process that the transmission number of plies M is determined can be with are as follows: the network equipment sends the first modulating-coding to terminal and indicates information, terminal receives first modulating-coding instruction information, and the first modulating-coding indicates to include the first MCS or the first RI in information, and terminal receives the first MCS and the first RI.First RI is the value range of the 2nd RI, and the first MCS is in the value range of the first RI restriction, for the initial value of the 2nd MCS of each transport layer under each optional RI.Terminal is by first The lower limit of value range is determined as the initial value of the 2nd RI in RI, and the MCS of each transport layer under the 2nd RI in the first MCS is determined as to the initial value of the 2nd MCS.When the number for the ACK information that terminal receives is greater than the first preset threshold value, terminal can increase the 2nd MCS, and the 2nd RI is constant；Alternatively, when the number for the ACK information that terminal receives is greater than the first preset threshold value, terminal can increase the 2nd RI, and determine that the MCS of each transport layer corresponded under the 2nd new RI in the first MCS is the 2nd MCS, the 2nd RI is transmission number of plies M.

Terminal can match the wave beam for the terminal side matched in set based on above-mentioned wave beam, and the wave beam or transmission rate for generating the terminal side that the transmission number of plies is the 2nd RI are the corresponding rate of the 2nd MCS to send physical layer data information.In addition, the 2nd RI and the 2nd MCS are sent to the network equipment by ascending physical signal control channel by terminal.In this way, the network equipment can receive ascending physical signal control channel, RI and MCS used in transmitting uplink data are determined, and then realize the decoding to upstream data packet.

Such as, first MCS is 5, first RI is 1 to 2, the initial value of 2nd RI can be the lower limit 1 of value range in the first RI, the initial value of 2nd MCS can be the first MCS, when the number for the ACK information that terminal receives is greater than the first preset threshold value, terminal can increase the 2nd MCS, for example increasing the 2nd MCS is 6, 2nd RI can be still constant for initial value, if the wave beam for the terminal side matched in above-mentioned wave beam pairing set is wave beam 1, 3 and 8, then terminal can pass through wave beam 1, one of wave beam in 3 and 8, physical layer data information is sent with the 2nd MCS=6 corresponding rate；Alternatively, terminal can also increase the 2nd RI, for example be increased to 2 when the number for the ACK information that terminal receives is greater than the first preset threshold value, the MCS of each transport layer under the 2nd RI can be constant for the initial value 5 of the second MCS, can also reduce.Such as, if the wave beam for the terminal side matched in above-mentioned wave beam pairing set is wave beam 1,3 and 8, then terminal all can send physical layer data information by any two wave beams, any two wave beams in wave beam 1,3 and 8 with the corresponding rate of the 2nd MCS initial value 5, or the one of wave beam of any two wave beams is that 4 corresponding rates send physical layer data information with the 2nd MCS, another wave beam is that 3 corresponding rates send physical layer data information with the 2nd MCS.

It is understood that the 2nd RI, i.e. terminal side send the transmission number of plies M of physical layer data information, the wave beam for the terminal side matched in set can be matched greater than zero and less than or equal to wave beam described in embodiment one.

Optionally, multiple subbands can also be divided into order to meet requirement of the different sub-band to service quality (Quality of Service, QoS), second area in second area.In multiple subbands that the second area divides, each subband can have different the transmission number of plies and the corresponding MCS of each transmission number of plies, terminal can match the wave beam of terminal side matched in set based on wave beam, generate the wave beam of the terminal side of the transmission number of plies of each subband and send physical layer data information with the corresponding MCS of each transmission number of plies；Or, in multiple subbands that the second area divides, each subband in a part of subband can have different the transmission number of plies and the corresponding MCS of each transmission number of plies, terminal can match the wave beam for the terminal side matched in set based on wave beam, generate the wave beam of the terminal side of the transmission number of plies of each subband, and physical layer data information is sent with each transmission number of plies corresponding MCS, wave of each OFDM symbol configured with a terminal side in above-mentioned wave beam pairing set in another part subband, terminal can send physical layer data information using the wave beam in configuration in the first region each OFDM symbol；Or, in multiple subbands that the second area divides, wave of each OFDM symbol configured with a terminal side in above-mentioned wave beam pairing set in each subband, terminal can send physical layer data information etc. using the wave beam in configuration in the first region each OFDM symbol.It should be noted that the configuration of the 2nd MCS and the 2nd RI and each subband on each subband, is sent to the network equipment by Physical Uplink Control Channel.In this way, the network equipment can receive ascending physical signal control channel, the subband that RI and MCS used in transmitting uplink data and uplink are divided is determined, and then realize the decoding to upstream data packet.

Wherein, the network equipment can pass through high-level signaling, such as the region division of radio resource control information transmission second area Information, in order to reduce the expense of signaling, in the second area, the division of subband, which be can be, is semi-statically configured.

For example, the second area shown in Fig. 3 C has divided two subbands, subband 1 and subband 2, and subband 1 is identical with 2 time domain of subband, frequency domain is different on the basis of Fig. 3 B.

As it can be seen that the first area of the embodiment of the present application, using diversity technique, diversity technique improves the quality of Physical layer control information transmission, second area improves the quantity of physical layer data information transmission using space multiplexing technique.
