Embodiments of the present disclosure describe methods and apparatuses for communicating in underlay infrastructure-less networks.

Description

Sub-frame structure for communication in the underlying infrastructureless network

The embodiments of the present invention generally relate to the field of networking, and more specifically, to devices, systems, and methods for communicating in an underlying infrastructureless network.

The current short-range wireless personal area network technology is limited by the data rate, and many devices communicating in a relatively small area result in poor performance in ultra-dense deployments. Other wireless local area network technologies consume relatively large amounts of power and may not be suitable for small portable devices.

In the following detailed description, reference is made to the drawings forming a part thereof, in which similar reference signs always indicate similar parts, and which It is shown by illustrating practical examples. It should be understood that other embodiments may be used and structural or logical changes may be made without departing from the scope of the present invention.

Various operations can be described in sequence as multiple independent actions or operations in a manner that is most helpful for the understanding of the claimed subject matter. However, the order of description should not be interpreted as implying that these operations are necessarily order-dependent. In particular, these operations may not be performed in the order of presentation. The described operations can be performed in a different order from the described embodiments. In additional embodiments, various additional operations may be performed or the described operations may be omitted.

For the purpose of the present invention, the terms "A or B", "A and/or B" and "A/B" mean (A), (B) or (A and B).

The description may use the terms "in an embodiment" or "in multiple embodiments," which may each refer to one or more of the same or different embodiments. In addition, the terms "including", "including", "having" and the like used in the embodiments of the present invention are synonymous.

FIG. 1 shows a communication system 100 for supporting wearable user equipment ("wUE") according to some embodiments. Although the embodiments are described with respect to wearable devices, these concepts can also be applied to other non-wearable devices that communicate via a personal area network ("PAN").

The entity of the system 100 includes a network user equipment ("nUE") 110 with a complete infrastructure network access protocol stack (e.g., for complete control plane and user plane functions); wUE 120 (e.g., 120a, 120b) And 120c), which lack an independent network access connection, and The nUE 110 is used for network access and coordination; evolved node B ("eNB") (or more generally, base station) 130; and evolved packet core ("EPC") 140. The nUE 110 and one or more wUEs 120 may authenticate each other to form one or more underlying networks, such as PAN. The PAN may not be scheduled by a central scheduling entity (such as eNB 130), and therefore may be referred to as an uncoordinated or infrastructureless network in some embodiments.

The air interface between the entities of the system 100 may include the S1 interface 145 between the EPC 140 and the eNB 130; the Uu-p interface 150 between the nUE 110 and the eNB 130; the (higher power) interface between the wUE 120a and the eNB 130 Requirements) Uu-w interface 160a (similar Uu-w interfaces are not shown for wUE 120b and wUE 120c, but may exist in some embodiments); nUE 110 and Xu-a interface 170 between wUE 120a and wUE 120b ( For example, the Xu-a interfaces 170a and 170b); and the Xu-b interface 180 between wUE 120b and wUE 120c (other Xu-b interfaces are not shown, but may exist in some embodiments). Generally speaking, the Xu-a interface can provide the air interface in the PAN between the nUE and the related wUE, and the Xu-b interface can provide the air interface in the PAN between the wUE, but the design principles described here may be applicable Xu-a or Xu-b interface (usually called Xu interface).

FIG. 2 is a hierarchical description of the structure of the radio frame 200 according to some embodiments. The structure of the radio frame 200 and the sub-frames contained therein can organize and facilitate communication between components of the underlying infrastructureless network such as the PAN introduced in FIG. 1.

The radio frame 200 may include time-sharing duplex ("TDD") the subframe structure 210, the system bandwidth 220 allocated in the subchannel 230, and the TDD-based channel 240 allocated in the subchannel 230.

The radio frame 200 displays ten sub-frames, but the number of sub-frames in each frame can be greater than or less than ten. Among the sub-frames in each frame, at least one sub-frame can be pre-configured as a DL sub-frame. For example, Figure 2 shows subframe #0 as the DL subframe, although other assignments are possible. Other sub-frames can be flexibly configured as DL or UL sub-frames, which can be represented by the "DL/UL" symbol in FIG. 2.

DL and UL transmissions can be dynamically scheduled in each PAN. In each sub-frame, some PANs can be sent in the UL direction with the resource allocation they have acquired, and some PANs can be sent in the DL direction with the resource allocation they have acquired.

The smallest unit of physical resources available in the radio frame 200 may be referred to as a resource element (RE) of one symbol and one subcarrier. (In time and frequency) The blocks of adjacent REs form physical resource blocks (PRBs). Two PRBs that are adjacent in time may be referred to as a pair of PRBs. In some embodiments, the sub-channel has a sub-channel bandwidth corresponding to multiple pairs of PRBs. The subchannel bandwidth can then be divided according to the physical resource allocation (PRA) allocated for communication between the nUE 110 and the related wUE 120. An example of the resources available in the radio frame 200 is set forth in Table 1.

Each nUE can determine the degree of aggregation of PRA. The aggregation degree of the PRA of each nUE can be consistent in one subframe. Related wUEs can perform blind detection on a sub-channel to try different aggregation levels. Generally, when multiple UEs in a coverage area share common resources, blind detection can be used. Therefore, each UE can blindly detect its own control or data information in the resource, for example, by decoding all the information to obtain information that is targeted to a specific wUE. After detecting the degree of aggregation, wUE can use the same degree of PRA aggregation for detecting other channels.

Referring again to Figure 1, the Xu-a and Xu-b interfaces represent the interfaces of various PANs. The challenges of this network (or any uncoordinated underlying network) can include: uplink transmission (for example, from wUE 120 to nUE 110) and downlink within PAN (or closed access unit in the underlying network) Conflicts between link transmissions (for example, from nUE 110 to wUE 120) cause, for example, interference in wUE; conflicts between PANs (or closed access units in the underlying network); fast power control and link adaptation Configuration; multiple users and multiple tasks within each PAN (or closed access unit); and timely receipt of confirmation feedback.

The various embodiments described herein provide sub-frame structures that at least partially solve the above-mentioned problems. The sub-frame structure of the embodiment can facilitate the PAN scheduling and management of the master node (for example, nUE), and may include: physical channels or communication instances/components to coordinate the internal transmission direction of the PAN (for example, uplink or Downlink transmission direction); physical channels or communication instances/components used to coordinate resource allocation between PANs; physical channels or communication instances/components used for radio resource management ("RRM") measurements; entities used to receive confirmation Channels or communication instances/components; or physical channels or communication instances/components used for slave nodes (for example, wUE) to request scheduling for transmission.

Figure 3 shows the structure of a sub-frame according to some embodiments. Specifically, according to some embodiments, FIG. 3(a) shows the downlink sub-frame 310, and FIG. 3(b) shows the uplink sub-frame 350.

The downlink subframe 310 may include multiple physical channels, including but not limited to: DL/UL control channel ("CC") 315; resource acquisition ("RA") channel 320; resource acquisition response ("RAR") channel 325 ; Data channel 330; and Acknowledgment ("ACK") channel 335. Each physical channel can be separated by a protection period ("GP") 340, such as GP 1-5 shown in Figure 3(a). The guard period can be provided to adapt to the time of DL/UL switching, demodulation and decoding, and round-trip propagation time.

The uplink sub-frame structure 350 may include physical channels similar to those described above with respect to the downlink sub-frame 310. For example, the physical channel of the uplink subframe structure 350 may include but is not limited to: DL/UL control channel 355; RA channel 360; RAR channel 365; data Channel 370; and ACK channel 375. Each physical channel can be separated by GP 380, for example, GP 1-5 shown in Figure 3(b).

The DL/UL control channel, for example, the DL/UL control channel 315 or the DL/UL control channel 355 may be used to transmit the DL/UL control signal from the nUE 110 to the wUE 120 indicating the transmission direction of the subframe. For example, the DL/UL control channel 315 may include a DL/UL control signal to indicate that the downlink subframe 310 has a downlink transmission direction, for example, the transmission direction from the nUE 110 to the wUE 120. For another example, the DL/UL control channel 355 may include a DL/UL control signal to indicate that the uplink subframe 350 has an uplink transmission direction, for example, the transmission direction from wUE 120 to nUE 110.

In some embodiments, the wUE having an interface with the nUE 110 can be regarded as a proxy for the nUE 110 for inter-wUE communication through the Xu-b interface for the purpose of determining the uplink and downlink transmission directions. For example, the downlink transmission may be from wUE 120b to wUE 120c, and the uplink transmission may be from wUE 120c to wUE 120b.

The RA channel, for example, the RA channel 320 or the RA channel 360 can be used to transmit the RA control signal by the transmitter of the subframe. As used here, if the subframe is a DL subframe, such as DL subframe 310, the sender of the subframe may refer to nUE 110 (or its proxy), and if the subframe is a UL subframe, For example, the UL subframe 350 may refer to wUE. The RA control signal can be used by the transmitter to obtain PRB in, for example, time, frequency, or space.

The RAR channel can be used for transmission by the receiver of the subframe RAR control signal. As used herein, if the sub-frame is a DL sub-frame, such as DL sub-frame 310, the receiver of the sub-frame may refer to wUE, and if the sub-frame is a UL sub-frame, such as UL sub-frame 350 , Can refer to nUE 110 (or its agent). The RAR control signal can be used by the receiver to confirm the reception of the RA control signal in the RA channel.

The data channel, such as the data channel 330 or the data channel 370, can be used to transmit user plane or control plane data from the sender of the subframe. For example, the data channel 330 can be used to transmit user plane or control plane data from the nUE 110 (or its proxy) to the wUE; and the data channel 370 can be used to transmit user plane or control plane data from the wUE 120 to the nUE 110. Or an agent.

The acknowledgment channel, for example, the ACK channel 335 or the ACK channel 375 can be used to transmit the ACK control signal by the receiver of the subframe. The ACK control signal may include a positive acknowledgment ("ACK") for indicating the successful reception of the subframe or a negative acknowledgment ("NACK") for indicating the unsuccessful reception of the subframe.

In some embodiments, a scheduling request ("SR") channel may be used to transmit SR control signals from wUE 120 to the nUE (or its proxy) to request resource allocation for uplink transmission. The SR channel can be multiplexed with one of the above-mentioned physical channels. For example, in some embodiments, the SR channel may be multiplexed with the RA channel, RAR channel, or ACK channel.

Table 2 shows the content of the physical channel according to some embodiments.

As shown in Table 2, the DL/UL control signal can include a bit that provides DL/UL indication. This bit can be repeated nine times to provide a 10-bit payload. Cyclic Redundancy Check ("CRC") can be embedded in In the DL/UL control signal, it can then be mixed with 10 bits corresponding to the temporary identification code ("wUE temporary ID") of the wUE that communicates with the nUE through the subframe. In some embodiments, the wUE temporary ID may be an identifier generated from the media access control address of the wUE. During PAN internal communication, wUE temporary ID can be used to identify wUE.

The RA control signal of the DL subframe may include a new data indicator ("NDI"), which may be a bit that indicates to the wUE 120 that the nUE 110 wants to send new data. This bit can be repeated nine times to provide a 10-bit payload. The CRC can be embedded in the RA control signal, which can then be mixed with 10 bits of the temporary identification code of the wUE corresponding to the indicated new data.

In some embodiments, the RA control signal may also include a hybrid automatic repeat request ("HARQ") program index, redundancy version, and so on.

In some embodiments, the RA control signal may also carry reference signals that can be used for RRM operations such as scheduling, link adaptation, data demodulation, power control, handover, and the like. For example, the RA control signal may include a demodulation reference signal, which can be used by the receiver to assist in the demodulation of the data sent in the data channel. For another example, the RA control signal can include a channel status information reference signal, which can be used by the receiver to measure the channel status that can be used as a basis for link adaptation.

The RAR control signal of the DL subframe can be sent by the wUE 120 and can indicate which modulation and coding scheme ("MCS") should be used by the nUE 110 in the downlink transmission. The RAR control signal can also provide a downlink power headspace report ("PHR") to indicate the transmission of RA The difference between the transmission power and the power required to support the selected MCS. This can be used by the nUE 110 to adjust the power of the downlink transmission. Based on the reference signal sent in the RA control signal, the MCS and DL PHR can be determined by the wUE 120. In some embodiments, the RAR control signal of the DL subframe may also include CRC. As shown in Table 2, the RAR control signal of the DL subframe can be 10 bits, of which four bits are used for MCS, two bits are used for DL PHR, and four bits are used for CRC. The 10 bits of the RAR control signal of the DL subframe can be mixed with the temporary identification code of the wUE 120.

The RA control signal of the UL subframe may be sent by the wUE 120 to provide the nUE 110 with an indication that the wUE 120 has data to be sent. If the wUE 120 has data to be sent, the RA control signal may include 10 bits set to "1", which can be mixed with the temporary identification code of the wUE 120. In some embodiments, the RA control signal may also include one or more reference signals, such as the signals described above regarding the RA control signal of the DL subframe.

The RAR control signal of the UL subframe can be sent by the nUE 110 to confirm the successful reception of the RA control signal. In some embodiments, the RAR control signal may additionally/alternatively carry transmission scheduling information for scheduling the transmission power and rate of the subframe. For example, in some embodiments, the RAR control signal may indicate which MCS the wUE should use in uplink transmission, and may also indicate the UL PHR to indicate the difference between the transmission power of the RA and the power required to support the selected MCS . The reference signal of the RA control signal based on the UL subframe can be determined by the nUE 110 Set MCS and PHR. In some embodiments, the RAR control signal of the UL subframe may also include CRC. As shown in Table 2, the RAR control signal of the UL sub-frame can be 10 bits, of which four bits are used for MCS, two bits are used for UL PHR, and four bits are used for CRC. The ten bits of the RAR control signal of the UL subframe can be mixed with the temporary identification code of the wUE 120.

The ACK control signal of the DL subframe can be sent by the wUE 120 to positively or negatively confirm the reception of the data transmission from the wUE 120. In some embodiments, the ACK control signal of the DL subframe may include one bit, for example, set to "1" to indicate a positive acknowledgement ("ACK"), and "0" to indicate a negative acknowledgement ("NACK"). This bit can be repeated five times, and the resulting six-bit sequence contains an embedded CRC. In some embodiments, the ACK control signal of the DL subframe may also include a buffer status report ("BSR"), which provides an indication of the size of the transmit buffer of the wUE 120, for example, the TX/RX in FIG. 7 Buffer 736.

The BSR that may be sent only in the control PRA (for example, the PRA carrying the control plane packet) may be an opportunistic BSR that is sent together with the ACK control signal for DL transmission when the wUE 120 has UL data to send.

In some embodiments, the BSR index, which can be represented by four bits, can correspond to the buffer size value shown in Table 3.

The ten-bit ACK control signal of the DL subframe can be mixed with the temporary identification code of the wUE 120.

If the wUE 120 does not receive the data transmission correctly and there is no BSR to send, it may not send the ACK control signal in the DL subframe. In these cases, the nUE 110 may interpret the non-reception of the acknowledgement control signal as a NACK. In some embodiments, if the probability of false alarms or missed detections becomes too high, other mechanisms may be used, such as an explicit transmission that requires a negative confirmation.

The ACK control signal of the UL subframe can be sent by the nUE 110 to positively or negatively confirm the connection of the data transmission from the wUE 120. receive. In some embodiments, the ACK control signal of the UL subframe may include one bit, for example, set to "1" to indicate a positive confirmation. This bit can be repeated nine times to provide a 10-bit sequence. The 10-bit sequence can be mixed with the temporary identification code of wUE 120. In some embodiments, the ACK control signal of the UL subframe may not be sent for negative confirmation. In these cases, wUE 120 may interpret the non-reception of the acknowledgement control signal as NACK.

In some embodiments, the ACK control signal can use repetition or CRC for robustness.

In some embodiments, the BSR can be sent in the UL subframe by carrying the BSR with control plane or user plane data in the MAC protocol data unit sent in the control PRA.

The SR control signal may be sent by wUE 120 to request resource allocation for uplink transmission. In some embodiments, the SR control signal may include 10 bits to represent the temporary identification code of wUE 120, four bits are used for BSR, and four bits are used for CRC. The 18 bits of the SR control signal can be mixed with the temporary identification code of wUE 120.

Figure 4 shows a downlink signaling subframe 400 for PAN according to some embodiments. In this embodiment, similar to what is described above with respect to Table 2, the DL/UL control channel may be wUE specific. For example, through the resources intended for wUE, the DL/UL control channel that nUE 110 can send for each wUE of the PAN is marked as PAN #1 in FIG. 4.

Downlink signaling subframe 400 specifically includes PRB 410, PRB 420, PRB 430 and PRB 440. In this embodiment, nUE 110 may have determined that two PRBs are required to convey downlink data to wUE # 1 (therefore, the PRA used for wUE # 1 is equal to two PRBs); and one PRB is required to transmit the downlink data. Road information is conveyed to each of wUE # 2 and wUE # 3. Therefore, the nUE 110 can provide DL/UL control signals mixed with the temporary identification code of wUE # 1 in the DL/UL control channels of both PRB 410 and PRB 420; in the DL/UL control channel of PRB 430, wUE DL/UL control signal mixed with temporary identification code #2; and DL/UL control signal mixed with temporary identification code #3 in the DL/UL control channel of PRB 440.

Each wUE can try to decode the DL/UL channel in each PRB of PAN #1 using their respective temporary identification code. wUE # 1 can successfully decode DL/UL channels in both PRBs 410 and 420, and may unsuccessfully decode DL/UL channels in PRBs 430 and 440; wUE # 2 can successfully decode DL/UL channels and PRBs 430, and may unsuccessfully decode DL/UL channels in PRBs 410, 420, and 440; and wUE #3 may successfully decode DL/UL channels and PRB 440, and may unsuccessfully decode PRBs 410, 420, and 430 DL/UL channel. In this way, each wUE may be able to determine which PRAs have their information.

Figure 5 shows a downlink signaling subframe 500 for PAN according to some embodiments. In this embodiment, the DL/UL control channel may be PAN specific. For example, the nUE 110 may use the temporary identification code of the nUE 110 to mix DL/UL control signals. Therefore, DL/UL control The channel may be common to all wUEs of PAN #1. The nUE 110 may broadcast DL/UL control signals in the DL/UL control channel of all resources it intends to acquire for PAN #1. For example, the same DL/UL control signal can be sent in the DL/UL control channels of PRBs 510, 520, 530, and 540. Then, the RA and RAR channels that may be wUE-specific can be used to complete the resource acquisition of each wUE in PAN #1.

For example, all wUEs of PAN #1 can determine that PRBs 510, 520, 530, and 540 will be used as downlink subframes by receiving and successfully decoding UL/DL control signals in different UL/DL control channels. However, at this moment, the wUE may still not know which (if any) PRBs will contain information for different wUEs. This determination may occur when decoding is performed on the RA channel of the respective PRA. For example, wUE # 1 can successfully decode the RA channels in both PRBs 510 and 520, and may unsuccessfully decode the RA channels in PRBs 430 and 440; wUE # 2 can successfully decode the RA channels and PRB 430, and The RA channels in PRBs 410, 420, and 440 may be unsuccessfully decoded; and wUE #3 may successfully decode the RA channels in PRB 440, and may unsuccessfully decode the RA channels in PRB 410, 420, and 430. At this moment, each wUE may be able to determine which PRB has its information.

In some embodiments, the DL/UL control channel may also be PAN specific in the uplink. In this embodiment, the nUE 110 may receive DL/UL control signals in one or more PRBs that the wUE wishes to utilize. The nUE 110 can use the temporary identification code of the nUE 110 to decode the DL/UL control signal. At this moment, nUE 110 may not know the PAN Which wUE should send uplink data. However, the nUE 110 may try to use a different temporary identification code to decode the RA control signal in the RA channel. When the RA control signal is successfully decoded, the nUE 110 can determine which wUE is to send uplink information.

Figure 6 shows a downlink signaling subframe 600 for two PANs according to some embodiments. In this embodiment, the nUE 110 may only send the PAN-specific DL/UL control signal in the first PRB of the continuously allocated resource block that it intends to acquire for the PAN. For example, nUE #1 can send DL/UL control signals in the DL/UL control channel of PRB 610, and nUE #2 can send DL/UL control signals in the DL/UL control channel PRB 650. Each DL/UL control signal can be mixed with its own temporary identification code of nUE.

When wUE detects a PRB carrying DL/UL control information sent from the desired nUE, wUE can then detect the subsequent PRB to the point where the conflict is detected (for example, when wUE cannot detect the DL/UL control channel) Determine the size of contiguous resource blocks. For example, the wUE of PAN # 1 can use the temporary identification code of nUE # 1 to decode the DL/UL control signal in the DL/UL control channel of PRB 610, and can successfully use the temporary identification code of nUE # 1 A point of the DL/UL control signal in the DL/UL control channel of the PRB 650 is decoded to detect the collision in the PRB 650.

The resource acquisition of each wUE in PAN #1 can then be completed by RA and RAR channels in consecutive resource blocks indicated by the DL/UL control channel. This can be done similarly as described above with respect to Figure 5. Row.

In some embodiments, various mechanisms may be used to reduce the search space size and detection effort of wUE. In the first example, the nUE can obtain continuous blocks of PRBs from the eNB. Then, the nUE can map the index of the first PRB obtained by the nUE to the wUE temporary ID (in the case of the wUE specific DL/UL control channel) or the nUE temporary ID (in the case of the PAN specific DL/UL control channel) . Knowing the nUE temporary ID or its own temporary ID will allow the wUE to locate the first PRB of the resource allocation that can start detection. Then, wUE can start decoding the DL/UL channel until a decoding failure occurs. In this way, wUE does not need to detect the entire bandwidth.
