  • the design is wUE centric and includes a wUE-specific physical control and data channel to minimize wUE blind detection.
  • blind detection is used because each base station provides a common control channel, and multiple UEs in the coverage region share that common resource. Accordingly, each UE blindly detects in that channel its own control resource, e.g., decoding all of the control channel.

  • FIG. 2 illustrates an L1 procedure 200 for establishing an Xu-a interface.
  • a wUE 210 turns on or otherwise becomes active for transmitting or receiving communications, it synchronizes with a synchronization source (SS) nUE 220 or with a donor nUE 230 of the wUE 210 (i.e., when the donor nUE 230 is itself acting as a synchronization source) and reads system information.
  • SS synchronization source
  • the wUE 210 sends an RA message in a selected block of resources in an RA channel.
  • the donor nUE 230 responds with an RAR in a resource block (i.e., a group of resource elements defined by subcarriers and symbols) having a physical location in an RAR channel corresponding to that of the RA. Examples of the corresponding locations are shown in FIG. 5. Accordingly, the transmission of RAR is free from collisions.
  • the wUE To receive the RAR, the wUE monitors the location of the resource block it had used to send the RA. Therefore, blind detection at the wUE is avoided. In the RAR, a bitmap indicating the resource assignment for the data transmission of the wUE will be transmitted along with other information. The wUE can then proceed with DL/UL traffic in the scheduled resource(s).
  • FIG. 3 shows a timing diagram 300 of logical multiplexing of physical channels.
  • Component physical channels in the Xu-a interface include: a physical synchronization channel 310; a physical broadcast channel 320; a physical RA channel 330; a physical RAR channel (optionally including paging and initial scheduling assignment (SA)) 340; a dedicated physical control channel 350; and a physical data channel 360.
  • SA initial scheduling assignment
  • the logical multiplexing shows that there are synchronization intervals 380 provided every radio frame. Within some synchronization intervals, there is a partly overlapping RA and paging interval 390.
  • Synchronization may be achieved by a single-frequency-network (SFN) type of synchronization, in which the nUEs and wUEs within one cluster (also called a synchronization cluster) are synchronized based on propagation of a single SS.
  • a synchronization cluster may have multiple PANs. For example, a wUE may be in range of a first nUE but out of range of a second nUE, but the nUEs are still synchronized because they can hear each other's broadcast channel. Accordingly, all the nUEs and wUEs within a cluster are synchronized through a common synchronization channel.
  • the base station optionally maintains synchronization by providing, for example, primary/secondary synchronization signals (PSS/SSS). Because there is a common synchronization, the design may maintain a radio frame boundary aligned among the PANs for reduced collision avoidance.

  • Two of the nUEs 410 are also acting as an SS 440, broadcasting a common synchronization signal at the same time so as to extend the coverage of the cluster 400.
  • An nUE becomes an SS by determining whether it satisfies certain criteria.
  • the criteria can be based on: whether the nUE has residual power (e.g., battery power) available above a certain threshold and suitable for higher power SS transmissions; the received power of the synchronization signal at the nUE is below a certain threshold; or other criteria.

  • the bitmap for RA resource allocation may be a string of bits having binary values indicating whether a resource block corresponding to the bit location may be used for RA. Based on this information, the wUE will know the resource it can use for sending RA.
  • Each of the wUEs seeking to perform RA randomly selects at least one resource block in the RA region and transmits an RA message for a particular donor nUE.
  • the donor nUE identifies that the RA message is addressed to it, and responds to the wUE (and any other wUEs using different resource blocks) using the same location of the resource block that the wUE had used for transmitting the RA.
  • the RAR from the nUE will be free from collisions.
  • FIG. 5 illustrates a pair of RA and RAR resource partition grids 500.
  • Each block in a grid represents one resource block in the RA and RAR regions.
  • each wUE randomly picks one or more resource blocks from the RA partition grid.
  • a total number of resource blocks each wUE may randomly select from the grid is predefined. Because each wUE randomly selects its resource blocks, there is some chance of collision between wUEs selecting the same block. But wUEs may take multiple blocks for transmitting redundant RA messages, which improve the likelihood that one of the blocks will not collide and that the nUE will receive at least one of the RA messages. In the example shown by blocks sharing a same type of shading in FIG.
  • each wUE takes two randomly selected resource blocks (e.g., block numbers 3 and 21 , which share a type of Crosshatch shading pattern). Also, when transmitting RA, power boosting can be applied when needed to ensure high access probability (e.g., initial access, high priority access).

  • the information contained in the RA may include (the number of bits are listed as examples): wearable RA radio network temporary identifier (w-RA-RNTI, 16 bits); wUE MAC address or other network identifier (48 bits, for first time access) or wearable cell radio network temporary identifier (w-C-RNTI, 16 bits, for idle wUE); or buffer status report (8 bits).

  • wearable cell radio network temporary identifier w-C-RNTI, 16 bits, for idle wUE
  • buffer status report 8 bits.
  • the RA preamble configuration could be common to all PANs in the cluster. This allows open-accessible nUEs to admit wUEs.
  • each of the corresponding donor nUEs responds to each of the wUEs by using resource blocks in the RAR grid having the same relative location as those used in the RA grid. For example, the nUE might receive one of the non- colliding messages from RA block number 3, and therefore the nUE provides the RAR in RAR block number 3.
  • the information contained in the RAR may include (the number of bits are listed as examples): w-RA-RNTI (16 bits); w-C-RNTI (16 bits); nUE id (10 bits);
