Description

Method and device used in user equipment and base station for wireless communication

Technical Field

The present application relates to a transmission method and apparatus in a wireless communication system, and in particular, to a method and apparatus for data channel transmission when a 5G and narrowband internet of things system coexist.

Background

The narrowband Internet of Things (NB-IoT-Narrow Band Internet of Things) is an emerging technology in the IoT field, wherein the NB-IoT is constructed in a cellular network, only consumes about 180KHz of bandwidth, and can be directly deployed in a traditional network so as to reduce the deployment cost and realize smooth upgrade; or may be deployed independently. At present, the NB-IoT deployment modes mainly include a stand-alone (stand alone) mode, an LTE guard band (Guardband) mode and an LTE in-band (Inband) mode. The independent mode corresponds to a network sharing frequency band resource which is not the same as that of the traditional LTE (Long Term Evolution) and LTE-Advance (enhanced Long Term Evolution), the transmission of NB-IoT corresponding to the LTE guard band mode occupies the guard band resource of LTE and LTE-A, and the NB-IoT corresponding to the LTE in-band mode shares the same bandwidth with LTE and LTE-A. When an LTE in-band mode is adopted, the center frequency point of the subcarrier corresponding to NB-IoT transmission needs to be aligned with the center frequency points of LTE and LTE-a transmission to avoid Inter-carrier Interference (Inter-carrier Interference); for the standalone mode, the above limitations need not exist. In the existing NB-IoT of Release-13 and Release-14, NB-IoT in independent mode and NB-IoT in-band mode correspond to different subcarrier center frequency points, respectively, and the base station informs UE (User Equipment) of the mode type through system information to help the UE determine the position of the subcarrier center frequency point.

The problem of coexistence of the 5G NR (New Radio Access Technology) system and the NB-IoT system still remains, and the above problem still needs to be researched and solved.

Disclosure of Invention

At present, an NB-IoT system informs NB-IoT UE of the type of the mode adopted by a base station through NB-IoT system broadcast information so as to help the NB-IoT UE to determine the relevant information such as a central frequency point, a rater-offset (cluster offset), resource mapping and the like; currently, 2-bit information is used to indicate one of the standalone mode, the LTE guardband mode, and the LTE inband mode. In the future, if there may be an NR system and an LTE system on one frequency band resource at the same time, and there are many different system designs for the NR and LTE systems, for NB-IoT UEs, five different deployment manners, i.e., an independent mode, an LTE guardband mode, an LTE inband mode, an NR guardband mode, and an NR inband mode, need to be distinguished; a simple solution to the above problem is to extend the existing system broadcast information to meet the added pattern, and then this solution has the problem of increasing the complexity of NB-IoT UE distinguishing patterns and increasing the overhead of NB-IoT system broadcast messages; at the same time, the above approach is not applicable to legacy NB-IoT UEs, which cannot see the newly added patterns, and thus need to upgrade deployed and mass-produced NB-IoT UEs, which is obviously not a way desired by NB-IoT device manufacturers.

Based on the above problems and analysis, the present application discloses a solution. Without conflict, embodiments and features in embodiments in the user equipment of the present application may be applied to the base station and vice versa. The embodiments and features of the embodiments of the present application may be combined with each other arbitrarily without conflict.

The application discloses a method used in a user equipment for wireless communication, characterized by comprising:

receiving a first signaling;

operating the first wireless signal;

wherein the first signaling is used to indicate a first set of subcarriers and a second set of subcarriers, the first set of subcarriers and the second set of subcarriers each comprising a positive integer number of subcarriers; the frequency domain resources occupied by the first wireless signal comprise the first subcarrier set and the second subcarrier set; the difference between the center frequency points of any two subcarriers in the first subcarrier set is positive integral multiple of the interval of the first subcarriers; at least one first subcarrier exists in the first subcarrier set, at least one second subcarrier exists in the second subcarrier set, and the difference between the central frequency point of the first subcarrier and the central frequency point of the second subcarrier cannot be evenly divided by the interval of the first subcarrier; the operation is a reception or the operation is a transmission.

As an example, the above method has the benefits of: the method does not change the existing NB-IoT UE, namely for the existing NB-IoT UE, the existing NB-IoT UE is indicated as an independent mode in an NR system without LTE service, and the NB-IoT UE works according to the existing system design corresponding to the independent mode; the key of this method is that for the normal NR UE, when the normal UE finds that the base station provides NB-IoT service through the standalone mode, the central frequency point of the subcarriers in the scheduled part of rb (resource block) needs to be adjusted to avoid interference to NB-IoT.

As an example, another benefit of the above method is: the first set of subcarriers corresponding to those RBs that overlap with the narrowband reserved for NB-IoT transmission and the second set of subcarriers corresponding to those RBs that do not overlap with the narrowband reserved for NB-oT transmission; and the normal UE adjusts the center frequency points of the subcarriers corresponding to the overlapped RBs according to an independent mode so as to avoid interference on the transmission of the NB-IoT.

According to one aspect of the application, the above method is characterized by comprising:

receiving first information;

wherein the first set of subbands includes S1 subbands of the first type, and the first information is used to indicate the S1 subbands of the first type; the first signaling is used for indicating K resource blocks, wherein L resource blocks in the K resource blocks are overlapped with frequency domain resources occupied by the first subband set; any subcarrier in the first subcarrier set belongs to the frequency domain resources occupied by the L resource blocks, and the first subcarrier set is orthogonal to the S1 first-class subbands in the frequency domain; the second set of subcarriers is orthogonal to the S1 first-type subbands in the frequency domain; said S1 is a positive integer; the K is a positive integer; the L is a positive integer not greater than the K.

As an example, the above method has the benefits of: the base station tells normal UE to reserve resources for NB-IoT through first information, namely the S1 first-class subbands; and the normal UE implicitly obtains the NB-IoT mode, namely the independent mode or the LTE in-band mode, through the bandwidth of each of the S1 first-class subbands, and further determines whether to reconfigure the RB colliding with the NB-IoT reserved resources to the center frequency point of the subcarrier according to the center frequency point of the NB-IoT subcarrier.

As an example, another benefit of the above method is: the normal UE only adjusts the central frequency points of the subcarriers corresponding to the L resource blocks overlapped with the frequency domain resources occupied by the first-class sub-band, and does not need to adjust all the scheduled K resource blocks; the method has the advantages of reducing the influence of NB-IoT on normal UE scheduling and improving the coexistence of NB-IoT and NR.

According to an aspect of the application, the above method is characterized in that the first set of subcarriers consists of K1 first-type subcarrier subsets, a given first-type subcarrier subset is one of the K1 first-type subcarrier subsets, and the subcarriers occupied by the given first-type subcarrier subset are discontinuous in the frequency domain; the second set of subcarriers consists of K2 subsets of subcarriers of a second type, a given subset of subcarriers of a second type is any one subset of subcarriers of the K2 subsets of subcarriers of a second type, the given subset of subcarriers of a second type occupies one resource block; the K1 is a positive integer and the K2 is a positive integer.

As an example, the above method has the benefits of: in order to avoid interference on NB-IoT, the part of originally scheduled frequency domain resources, which is overlapped with NB-IoT, does not send wireless signals, namely, subcarriers occupied by the given first type subcarrier subset are discontinuous in the frequency domain; meanwhile, the frequency domain resources coincident with the NB-IoT are coordinated only according to the granularity of the subcarriers, but not according to the granularity of the RB; that is, if some subcarriers in one RB coincide with NB-IoT, the remaining part of the RB that does not coincide with NB-IoT can still be used by normal UEs, thereby improving the spectrum efficiency.

According to an aspect of the application, the above method is characterized in that a first resource block and a second resource block both belong to the K resource blocks, the first resource block and the second resource block being contiguous in the frequency domain; the target first-class sub-band is one of the S1 first-class sub-bands, and the first resource block and the second resource block both overlap with the target first-class sub-band in the frequency domain; the frequency domain resources occupied by the first resource block comprise M1 subcarriers orthogonal to the frequency domain resources occupied by the target first-class subband, the frequency domain resources occupied by the second resource block comprise M2 subcarriers orthogonal to the frequency domain resources occupied by the target first-class subband, and the M1 subcarriers and the M2 subcarriers jointly form a first-class subcarrier subset in the K1 first-class subcarrier subsets; the M1 is a positive integer and the M2 is a positive integer.

As an example, the above method has the benefits of: and the subcarriers in the first resource block and the second resource block, which are collided by the NB-IoT, are vacant for the NB-IoT, and the rest subcarriers form a first type subcarrier subset, namely the rest subcarriers form a traditional RB to be used as the minimum frequency domain resource occupied by one-time scheduling, so that the scheduling of a base station is facilitated.

According to an aspect of the application, the above method is characterized in that a first resource block and a second resource block both belong to the K resource blocks, the first resource block and the second resource block being contiguous in the frequency domain; the target first-class sub-band is one of the S1 first-class sub-bands, and the first resource block and the second resource block both overlap with the target first-class sub-band in the frequency domain; the frequency domain resources occupied by the first resource block comprise M1 subcarriers orthogonal to the frequency domain resources occupied by the target first-class subband, the frequency domain resources occupied by the second resource block comprise M2 subcarriers orthogonal to the frequency domain resources occupied by the target first-class subband, the first subcarrier set consists of K1 first-class subcarrier subsets, and the M1 subcarriers and the M2 subcarriers belong to two first-class subcarrier subsets of the K1 first-class subcarrier subsets respectively; the M1 is a positive integer and the M2 is a positive integer.

As an example, the above method has the benefits of: and the subcarriers in the first resource block and the second resource block, which are collided by the NB-IoT, are used by the NB-IoT through puncturing (punture), and the rest subcarriers are respectively formed into two first-class subcarrier subsets, so that the realization is simplified, and the additional operation of normal UE and a base station during scheduling is avoided.

receiving second information;

wherein, the time domain resource occupied by the first wireless signal belongs to a first time unit; the second information is used to determine a target set of time units, the target set of time units including T1 target time units, the first time unit being one of the T1 target time units; the T1 is a positive integer; the second information is transmitted over an air interface.

As an example, the above method has the benefits of: the operation of adjusting the subcarrier center frequency point of the normal UE caused by the NB-IoT is limited in a part of time units, the interference of the NB-IoT on the scheduling of the normal UE is reduced, the base station can adjust the number of the time units occupied by the NB-IoT according to the traffic of the NB-IoT, the flexibility of system configuration is improved, and the spectrum efficiency is further improved.

Fig. 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane and the control plane, fig. 3 showing the radio protocol architecture for the User Equipment (UE) and the base station equipment (gNB or eNB) in three layers: layer 1, layer 2 and layer 3. Layer 1(L1 layer) is the lowest layer and implements various PHY (physical layer) signal processing functions. The L1 layer will be referred to herein as PHY 301. Layer 2(L2 layer) 305 is above PHY301 and is responsible for the link between the UE and the gNB through PHY 301. In the user plane, the L2 layer 305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the gNB on the network side. Although not shown, the UE may have several upper layers above the L2 layer 305, including a network layer (e.g., IP layer) that terminates at the P-GW on the network side and an application layer that terminates at the other end of the connection (e.g., far end UE, server, etc.). The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides header compression for upper layer data packets to reduce radio transmission overhead, security by ciphering the data packets, and handover support for UEs between gnbs. The RLC sublayer 303 provides segmentation and reassembly of upper layer packets, retransmission of lost packets, and reordering of packets to compensate for out-of-order reception due to HARQ (Hybrid Automatic Repeat reQuest). The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) in one cell among the UEs. The MAC sublayer 302 is also responsible for HARQ operations. In the control plane, the radio protocol architecture for the UE and the gNB is substantially the same for the physical layer 301 and the L2 layer 305, but without the header compression function for the control plane. The Control plane also includes an RRC (Radio Resource Control) sublayer 306 in layer 3 (layer L3). The RRC sublayer 306 is responsible for obtaining radio resources (i.e., radio bearers) and configures the lower layers using RRC signaling between the gNB and the UE.
