Abstract

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

Description

Subframe structure for communicating in an underlying infrastructure network

Embodiments of the present invention generally relate to the field of networking, and more particularly to apparatus, systems, and methods for communicating in an underlying infrastructure network.

Current short-range wireless personal area network technologies are limited by data rates, and many devices communicating in relatively small areas can 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.

SUMMARY OF THE INVENTION AND EMBODIMENT

In the following detailed description, reference is made to the accompanying drawings It is shown by illustrating an embodiment that can be practiced. It is understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the invention.

The various operations may be described as a plurality of independent acts or operations in a manner that is most helpful in understanding the claimed subject matter. However, the order of description should not be construed as meaning that the operations are necessarily sequential. In particular, these operations may not be performed in the order presented. The described operations may be performed in a different order than the described embodiments. In additional embodiments, operations that various additional operations may be performed or described may be omitted.

For the purposes 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 various embodiments", which may each refer to one or more of the same or different embodiments. Furthermore, the terms "comprising", "including", "having", and the like, are used in connection with the embodiments of the invention.

FIG. 1 shows a communication system 100 for supporting a wearable user device ("wUE") in accordance with some embodiments. While the embodiments are described in relation to wearable devices, these concepts can also be applied to other non-wearable devices that communicate over a personal area network ("PAN").

The entity of system 100 includes a network consumer device ("nUE") 110 having a complete infrastructure network access protocol stack (eg, for full control plane and user plane functionality); wUE 120 (eg, 120a, 120b) And 120c), which lacks a separate network access connection, and Network access is performed by and coordinated by nUE 110; 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 mutually authenticate to form one or more underlying networks, such as PANs. The PAN may not be scheduled by a central scheduling entity, such as eNB 130, and thus may be referred to as an uncoordinated or infrastructure-free network in some embodiments.

The air interface between the entities of system 100 may include an S1 interface 145 between EPC 140 and eNB 130; a Uu-p interface 150 between nUE 110 and eNB 130; (higher power between wUE 120a and eNB 130) Demand) Uu-w interface 160a (a similar Uu-w interface is not shown for wUE 120b and wUE 120c, but may be present 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 the wUE 120b and the wUE 120c (other Xu-b interfaces are not shown, but may be present in some embodiments). In general, the Xu-a interface can provide an air interface within the PAN between the nUE and the associated wUE, and the Xu-b interface can provide an air interface within the PAN between the wUEs, but the design principles described herein may apply to Xu-a or Xu-b interface (commonly referred to as the Xu interface).

2 is a hierarchical depiction of the structure of a radio frame 200 in accordance with 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 described in FIG.

The radio frame 200 can include time-based duplexing The sub-frame structure 210 ("TDD"), the system bandwidth 220 allocated in the sub-channel 230, and the TDD-based channel 240 allocated in the sub-channel 230.

The radio frame 200 displays ten sub-frames, but the number of sub-frames in each frame may be greater 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 a DL subframe, although other assignments are possible. Other subframes can be flexibly configured as DL or UL subframes, which can be represented in Figure 2 by the "DL/UL" symbol.

DL and UL transmissions can be dynamically scheduled in each PAN. In each subframe, some PANs may be sent in the UL direction with their acquired resource allocation, and some PANs may be sent in the DL direction with their acquired resource allocation.

The smallest unit of physical resources available in the radio frame 200 may be referred to as a symbol and a resource element (RE) of one subcarrier. The blocks of adjacent REs (in time and frequency) form a physical resource block (PRB). Two temporally adjacent PRBs may be referred to as a pair of PRBs. In some embodiments, the subchannels have subchannel bandwidths corresponding to pairs of PRBs. The subchannel bandwidth can then be partitioned according to the Physical Resource Allocation (PRA) assigned to the communication between the nUE 110 and the associated 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 the PRA. The degree of aggregation of the PRA of each nUE can be consistent in one subframe. The associated wUE can perform blind detection on one subchannel to try different levels of aggregation. In general, blind detection can be used when multiple UEs in a coverage area share a common resource. Thus, each UE can blindly detect its own control or profile information in the resource, for example by decoding all of the information to obtain information intended for a particular wUE. After detecting the degree of aggregation, the 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 the various PANs. The challenges of such a network (or any uncoordinated underlying network) may include: uplink transmissions (e.g., from wUE 120 to nUE 110) and downlinks within the PAN (or closed access units in the underlying network) Collisions between link transmissions (e.g., from nUE 110 to wUE 120) cause, for example, interference in the wUE; collisions between PANs (or closed access units in the underlying network); fast power control and link adaptation Provisioning; multi-user multiplex in each PAN (or closed access unit); and timely receipt of acknowledgment feedback.

The various embodiments described herein provide a subframe structure that at least partially addresses the above problems. The subframe structure of an embodiment may facilitate PAN scheduling and management of a primary node (e.g., nUE) and may include: a physical channel or communication instance/element to coordinate the transmission direction within the PAN (e.g., uplink or Downlink transmission direction); physical channel or communication instance/component to coordinate resource allocation between PANs; physical channel or communication instance/component for radio resource management ("RRM") measurements; entity for receiving acknowledgments A channel or communication instance/component; or a physical channel or communication instance/component for a slave node (eg, wUE) to request scheduling for transmission.

FIG. 3 shows the structure of a subframe according to some embodiments. Specifically, in accordance with some embodiments, FIG. 3(a) shows a downlink subframe 310, and FIG. 3(b) shows an uplink subframe 350.

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 acknowledge ("ACK") channel 335. Each physical channel may be separated by a guard period ("GP") 340, such as GP 1-5 as shown in Figure 3(a). A guard period can be provided to accommodate the time of DL/UL handover, demodulation and decoding, and round-trip propagation time.

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

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

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

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

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

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

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

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

Table 2 shows the contents of a physical channel in accordance with some embodiments.

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

The RA control signal of the DL subframe may contain a new data indicator ("NDI"), which may be a bit indicating to the wUE 120 that the nUE 110 is to transmit new material. The one-bit can be repeated nine times to provide 10 bit payloads. The CRC may be embedded in the RA control signal, which may then be mixed by 10 bits of the temporary identification code of the wUE corresponding to the indicated new material.

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

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

The RAR control signal of the DL subframe may be transmitted by the wUE 120 and may indicate which modulation and coding scheme ("MCS") the nUE 110 should use in the downlink transmission. The RAR control signal can also provide a downlink power headspace report ("PHR") to indicate the RA transmission. The difference between the power delivered and the power required to support the selected MCS. This can be used by nUE 110 to adjust the power of the downlink transmission. Based on the reference signal transmitted in the RA control signal, the MCS and DL PHR may be determined by the wUE 120. In some embodiments, the RAR control signal of the DL subframe may also include a 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 the MCS, two bits are used for the DL PHR, and four bits are used for the CRC. The 10 bits of the RAR control signal of the DL subframe can be mixed by 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 material to transmit. If the wUE 120 has material to transmit, the RA control signal may contain 10 bits set to "1", which may be mixed by 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 those described above with respect to the RA control signal of the DL subframe.

The RAR control signal of the UL subframe may be sent by the nUE 110 to confirm successful reception of the RA control signal. In some embodiments, the RAR control signal may additionally/alternatively carry transmission schedule information for the transmission power and rate of the scheduled subframe. For example, in some embodiments, the RAR control signal may indicate which MCS the wUE should use in the 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 confirmed by the nUE 110 Set MCS and PHR. In some embodiments, the RAR control signal of the UL subframe may also include a CRC. As shown in Table 2, the RAR control signal of the UL subframe can be 10 bits, wherein four bits are used for the MCS, the two-element UL PHR, and four bits for the CRC. The ten bits of the RAR control signal of the UL subframe may be mixed by the temporary identification code of the wUE 120.

The ACK control signal of the DL subframe may be sent by the wUE 120 to positively or negatively acknowledge receipt 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 acknowledgment ("ACK"), and "0" to indicate a negative acknowledgment ("NACK"). This bit can be repeated five times and the resulting six-bit sequence contains the embedded CRC. In some embodiments, the ACK control signal of the DL subframe may also include a buffer status report ("BSR") that provides an indication of the extent of the size of the transmit buffer of the wUE 120, eg, TX/RX in FIG. Buffer 736.

The BSR that may be transmitted only in the control PRA (e.g., the PRA carrying the control plane packet) may be an opportunistic BSR transmitted with the ACK control signal for DL transmission if the wUE 120 has UL data to transmit.

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

The tensor ACK control signal of the DL subframe may be mixed by the temporary identification code of the wUE 120.

If the wUE 120 does not correctly receive the data transmission and no BSR is to transmit, it may not send an ACK control signal in the DL subframe. In these cases, nUE 110 may interpret the unacknowledgment of the acknowledgment control signal as a NACK. In some embodiments, if the probability of a false alarm or missed detection becomes too high, other mechanisms may be used, such as an explicit transmission requiring a negative acknowledgement.

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

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

In some embodiments, the BSR may be transmitted in the UL subframe by piggybacking the BSR with control plane or user plane data in a MAC protocol data unit transmitted 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 contain 10 bits to represent the temporary identification code of the wUE 120, four bits for the BSR, and four bits for the CRC. The 18-bit element of the SR control signal can be mixed by the temporary identification code of the wUE 120.

FIG. 4 shows a downlink signaling subframe 400 for a PAN in accordance with some embodiments. In this embodiment, similar to that 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 transmit for each wUE of the PAN is labeled PAN #1 in FIG.

The downlink signaling subframe 400 specifically includes a PRB 410, PRB 420, PRB 430, and PRB 440. In this embodiment, nUE 110 may have determined that two PRBs are needed to communicate downlink data to wUE #1 (hence, the PRA for wUE #1 is equal to two PRBs); and a PRB is needed to downlink The road data is conveyed to each of wUE #2 and wUE #3. Therefore, the nUE 110 can provide the DL/UL control signal of the temporary identification code of the wUE #1 in the DL/UL control channel of both the PRB 410 and the PRB 420; by the wUE in the DL/UL control channel of the PRB 430 DL/UL control signal of the temporary identification code of #2; and DL/UL control signal of the temporary identification code of wUE #3 in the DL/UL control channel of the PRB 440.

Each wUE may attempt to decode the DL/UL channel in each PRB of PAN #1 using their respective temporary identification codes. wUE #1 may successfully decode DL/UL channels in both PRBs 410 and 420 and may not successfully decode DL/UL channels in PRBs 430 and 440; wUE #2 may successfully decode DL/UL channels and PRBs 430, and may not successfully decode DL/UL channels in PRBs 410, 420, and 440; and wUE #3 may successfully decode DL/UL channels and PRBs 440, and may not successfully decode PRBs 410, 420, and 430 DL/UL channel. In this way, each wUE can be able to determine which PRAs have their information.

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

For example, all wUEs of PAN #1 may 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 point, 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 may successfully decode the RA channels in both PRBs 510 and 520 and may not successfully decode the RA channels in PRBs 430 and 440; wUE #2 may successfully decode the RA channel and PRB 430, and The RA channels in PRBs 410, 420, and 440 may not be successfully decoded; and wUE #3 may successfully decode the RA channels in PRB 440 and may not successfully decode the RA channels in PRBs 410, 420, and 430. At this point, each wUE may be able to determine which PRBs have their 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 the DL/UL control signal in one or more PRBs that the wUE wishes to utilize. The nUE 110 may use the temporary identification code of the nUE 110 to decode the DL/UL control signal. At this moment, the nUE 110 may not know the PAN. Which wUE is to send uplink data. However, nUE 110 may attempt to decode the RA control signals in the RA channel using different temporary identification codes. When the RA control signal is successfully decoded, the nUE 110 can determine which wUE is to transmit uplink information.

FIG. 6 shows a downlink signaling subframe 600 for two PANs in accordance with some embodiments. In this embodiment, the nUE 110 may transmit the PAN-specific DL/UL control signal only in the first PRB of the consecutively allocated resource blocks it intends to acquire for the PAN. For example, nUE #1 may transmit a DL/UL control signal in the DL/UL control channel of the PRB 610, and nUE#2 may transmit a DL/UL control signal in the DL/UL control channel PRB 650. Each DL/UL control signal can be mixed with a temporary identification code of the respective nUE.

When the wUE detects a PRB carrying DL/UL control information transmitted from a desired nUE, the wUE may then detect the subsequent PRB to the point at which the collision is detected (eg, when the wUE cannot detect the DL/UL control channel) Determine the size of consecutive resource blocks. For example, the wUE of PAN #1 may use the temporary identification code of nUE #1 to decode the DL/UL control signal in the DL/UL control channel of the PRB 610, and may succeed in using the temporary identification code of nUE #1. A point in the DL/UL control signal in the DL/UL control channel of the PRB 650 is decoded to detect a collision in the PRB 650.

Next, the wUE can begin decoding the DL/UL channel until a decoding failure occurs. In this way, the wUE does not need to detect the entire bandwidth.
